The present invention relates to an adjustable positioning structure for a feeding support plate of a circular sawing machine which is capable of moving the feeding support plate to a predetermined position stably and accurately.
A conventional circular sawing machine is applied to cut a workpiece and contains a feeding support plate fixed on a side of a table of the circular sawing machine so as to feed and cut the workpiece stably and exactly according to using requirements.
Referring to
When desiring to moving the feeding support plate, the fixing lever is released, the hand wheel is rotated to drive the slider to move on the guide column, and the slider drives the feeding support plate to move toward the predetermined position. Thereafter, the fixing lever is fixed so as to position the slider with respect to the guide column, thus fixing the feeding plate troublesomely. Moreover, it is difficult to distinguish letters on the marking ruler, thus causing distinguishing error.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary aspect of the present invention is to provide an adjustable positioning structure for a feeding support plate of a circular sawing machine which contains a magnetic slider fitted on a guide column and configured to movably move and fix the feeding support plate, a micro pneumatic cylinder mounted on a bottom of the magnetic slider and configured to fix the magnetic slider, and a control button arranged on the feeding support plate and configured to control the micro pneumatic cylinder to actuate the magnetic slider to release or fix with respect to the guide column, such that a change of a magnet value of the magnetic slider is calculated and is displayed by a display on a side of the magnetic slider so that a user learns a displacement value of the feeding support plate based on the displacement value of the magnetic slider to determine whether the feeding support plate is moved toward the predetermined position.
Another aspect of the present invention is to provide an adjustable positioning structure for a feeding support plate of a circular sawing machine by which the control button is pressed to release the magnetic slider to move, and a change of a displacement value of the magnetic slider is calculated and is displayed by the display so as to move the feeding support plate to the predetermined position, thus adjusting the feeding support plate toward the predetermined position easily and exactly.
With reference to
The adjustable positioning structure for the feeding support plate 30 of a circular sawing machine 30 comprises: a magnetic element 41 accommodated therein and configured to produce a change of a magnet value of the magnetic slider 40 when the magnetic slider 40 moves along the guide column 22 reciprocately, such that a displacement value of the magnetic slider 40 is calculated and is displayed by a display 42 on a side of the magnetic slider 40; an calibration seat 23 fitted on the guide column 22 and located beside the other side of the magnetic slider 40 so as to reset the magnetic slider 40 to a zero; a marking sheet 24 fixed on the material feeding side of the table 21 of the circular sawing machine 20 so that a user distinguishes a movement of the magnetic slider 40; a micro pneumatic cylinder 43 mounted on a bottom of the magnetic slider 40 and configured to fix or release the magnetic slider 40 with respect to the guide column 22; and a control button 31 arranged on a top of the feeding support plate 30 and configured to control the micro pneumatic cylinder 43 to operate.
As desiring to adjust the feeding support plate 30 toward the predetermined position based on using requirements, the control button 31 is pressed to drive the micro pneumatic cylinder 43 to release the magnetic slider 40, and the feeding support plate 30 is manually moved to actuate the magnetic slider 40 to adjustably move on the guide column 22, such that the change of the magnet value of the magnetic slider 40 is calculated and is displayed by the display 42 so that the user learns a displacement value of the feeding support plate 30 based on the displacement value of the magnetic slider 40 to determine whether the feeding support plate 30 is moved toward the predetermined position. After fixing the feeding support plate 30, the control button 31 is released to actuate the micro pneumatic cylinder 43 to move the magnetic slider 40 to an original position with respect to the guide column 22. Preferably, the magnetic slider 40 is manually moved to abut against the calibration seat 23, thus resetting the magnetic slider 40 to the zero and adjusting the feeding support plate 30 easily and accurately.
Accordingly, the control button is pressed to drive the micro pneumatic cylinder to move the magnetic slider, and the feeding support plate is manually moved to actuate the magnetic slider to adjustably move on the guide column, such that the change of the magnet value of the magnetic slider is calculated and is displayed by the display, thus adjusting the feeding support plate toward the predetermined position easily and exactly.
In other words, it is easy to adjust the feeding support plate toward the predetermined position based on the using requirement by pressing the control button on the top of the feeding support plate, thus enhancing sawing operation.
While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
