1. Technical Field
The present disclosure relates a waxing device, generally to a waxing device of a polishing machine.
2. Description of Related Art
The housings of electronic devices need polishing to achieve a mirror finish. Polishing wheels of polishing machines may need a waxing treatment before using. Manual waxing is one method or procedure for such waxing treatment, but the whole procedure of manual waxing is both time and labor consuming. In addition, the waxing quality depends on the expertise and effort of the operators. In related art, waxing devices are applied to polishing wheels. However, pressures applied to the polishing wheels are non-uniform during the waxing process, which results in undue wear of the polishing wheels. Furthermore, such waxing devices need to adjust cutting tool after changing each new wax, and this consumes more time.
Therefore, there is room for improvement within the art.
The elements in the drawings are not necessarily drawn to scale, the emphasis instead placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

The driving mechanism 50 is positioned on the first sidewall 411. In illustrated embodiment, the driving mechanism 50 is a cylinder. The driving mechanism 50 includes a basing body 51 and a pushing member 53 movably positioned on the basing body 51. The basing body 51 is mounted on the first sidewall 411. The basing body 51 can drive the pushing member 53 into a reciprocating motion vertically with the sliding rail 17. The pushing member 53 includes a first connecting portion 531 and a second connecting portion 533. The first connecting portion 531 is movably positioned on the basing body 51. The second connecting portion 533 is substantially perpendicularly extending from an edge of the first connecting portion 531. The second connecting portion 533 is away from the mounting block 43.
The mounting assembly 60 is assembled with the second connecting portion 533. The mounting assembly 60 includes a mounting member 61 and a clamping element 65. The mounting member 61 is substantially a planar board. The mounting member 61 is installed on the second connecting portion 533. The mounting member 61 includes a first mounting surface 611 and a second mounting surface 613 positioned opposite to the first mounting surface 611. The first mounting surface 611 is adjacent to the driving mechanism 50. A shaft hole 615 and a mounting hole 617 are defined in the mounting member 61. An installing hole 651 is defined through the middle of the clamping element 65.
The motor 70 which includes a rotating shaft 71 is installed on the first mounting surface 611. The wax block 80 is substantially a thick disc with a through hole 83 in the middle thereof, and the periphery thereof is a round surface 81. The first rotating shaft 71 passes through the shaft hole 615 of the mounting member 61, the through hole 83 of the wax block 80, and finally assembles with the installing hole 651 of the clamping element 65. The wax block 80 rotatably sleeves on the first rotating shaft 71. The clamping element 65 sleeves on the first rotating shaft 71 and secures the wax block 80 in place.
The detecting assembly 90 is assembled with the mounting member 61 for detecting the consumption of the wax block 80. The detecting assembly 90 includes a detecting rod 91, a triggering end 93, a second rotating post 94, a detecting roller 95, and a detector 97. The detecting rod 91 includes a mounting end 911 and a detecting end 913. A rotating hole 915 is defined in the mounting end 911 and in the detecting end 913, respectively. The second rotating post 94 passes through the rotating holes 915 of the mounting end 911, the mounting hole 617 and the triggering end 93 for installing the detecting rod 91 on the second mounting surface 613 and the triggering end 93 on the first mounting surface 611. The triggering end 93 is able to rotate a same angle with the detecting rod 91 thereof. The detecting roller 95 is rotatably assembled with the detecting end 913 and rests lightly against the round surface 81. The detector 97 is positioned on the first mounting surface 611 between the motor 70 and the triggering end 93. A receiving groove 971 is formed in the detector 97 to receive the triggering end 93.
In assembly, the sliding rail 17 is fixed on the supporting base 13. The resisting mechanism 20 is positioned on the supporting base 13. The fixing block 15 is fixed on the supporting base 13. The adjusting base 41 and the pulley wheel 45 are assembled onto the sliding rail 17 and the fixing block 15, respectively. The mounting block 43 is mounted on the adjusting base 41. The extendable portion 23 resists the sensor 44. The driving mechanism 50 is connected with the first sidewall 411. The mounting member 61 is positioned on the second connecting portion 533. The motor 70 is positioned on the first mounting surface 611 so that the first rotating shaft 71 passes through the shaft hole 615. The wax block 80 and the clamping element 65 sleeve on the first rotating shaft 71. The wax block 80 is clamped between the clamping element 65 and the second mounting surface 613. The adjusting wire 47 hangs around the pulley wheel 45, and one end of the adjusting wire 47 is connected with the bolt 435. The hanging weight 49 hangs from the other end of the adjusting wire 47.
The wax block 80 is distant from the waxing wheel 200 at the beginning of the wax procedure. When the polishing wheel 200 needs to be waxed, the extendable portion 23 begins to draw or move backward, but doesn't leave the resisting groove 431. The sensor 44 detects action of the extendable portion 23 and begins to measure the waxing time. The adjusting base 41 also begins to move toward the polishing wheel 200 because of the decreasing resistance effect between the extendable portion 23 and the sensor 44. The driving mechanism 50, the mounting assembly 60, the motor 70 and the wax block 80 are also driven to move toward the polishing wheel 200 by the adjusting base 41.
The round surface 81 presses lightly on the surface of the polishing wheel 200 when the adjusting base 41 arrives at a preset position. The pushing member 53 begins to undergo a reciprocating motion when plumbed on the sliding rail 17. The wax block 80 is driven to rotate by the motor 70 and rotates the polishing wheel 200. The wax will be coated uniformly on the polishing wheel 200 by means of the friction between the wax block 80 and the polishing wheel 200. The extendable portion 23 pushes the mounting block 43 back to its initial position after the preset waxing time.
The detecting roller 95 resists against the round surface 81. The detecting rod 91 tilts with the decreasing diameter of the wax block 80. The triggering end 93 tilts accordingly toward the detector 97. The detector 97 issues a warning when the triggering end 93 arrives at within the receiving groove 971, which signifies that the wax block 80 needs to be changed or replaced. A new polishing wheel 200 is also needed when the wax block 80 becomes so worn out to the point that it cannot make contact with the polishing wheel 200 when the adjusting base 41 arrives at the preset position.
The waxing device 100 has a very simple arrangement and configuration. The adjusting base 41 slidably sleeves on the sliding rail 17. The resisting mechanism 20 resists the mounting block 43 for adjusting the pressure of the wax block 80 applied to the polishing wheel 200 during the waxing treatment procedure. The driving mechanism 50, the motor 70 and the wax block 80 are driven to move toward the polishing wheel 200 through the adjusting base 41. This means that the cutting tool adjusting process is not necessary when a new wax block 80 is substituted for a worn wax block 80. In addition, the circular wax block 80 replaces the traditional strip-shaped wax block. The wax block 80 retains a circular shape during this process. The wax block 80 is driven to move in two perpendicular directions, and this has the net result that allows for the wax to be coated uniformly on the polishing wheel 200. Furthermore, efficient consumption of the wax block 80 will be improved upon because the clamping of the wax block 80 requires the smallest possible area.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages.
