The present invention relates to a tenoner and particularly to a tenon fabrication machine that moves cutters smoothly and steadily, and allows a driving motor to be installed and removed quickly.
A conventional tenoner as shown in
In the event that malfunction occurs to the driving motor 2, and removal of the driving motor 3 for repairs is necessary, the entire moving dock 3 has to be removed from the two sliding rods 4. Removing and reinstallation have to be done by skillful professionals. Due to the moving dock 3 is coupled and involved, removing and reinstallation are tedious and troublesome.
In view of the aforesaid disadvantages occurred to the conventional tenoner, the primary object of the present invention is to provide a tenoner that has a chassis with a moving dock on the top. The moving dock has a sliding member on the bottom that is coupled on a sliding rod located transversely at the front side of the chassis. The moving dock is movable left and right on the sliding rod. The sliding member has a directing wheel at the front side. The directing wheel leans on a positioning rod from below. The positioning rod has notches on the front side. A directing rod is provided movable at the front of the positioning rod. The directing rod has a front end coupled with the moving dock. The moving dock has a rear side fastened to a connection board. The connection board has an opening in the center which is surrounded by a plurality of apertures. A driving motor is provided on the bottom of the connection board. The driving motor has an anchor ring on the top. The anchor ring has screw holes corresponding the apertures to be fastened by fastening elements after running through the connection board. Hence the driving motor can be moved left and right with the moving dock. The driving motor has a spindle on the top to hold a cutter. The cutter is exposed above the connection board to cut a work piece to form tenon ditches or tenon lugs. Through the moving dock which is slidable left and right the cutter can be moved flexibly forwards and rearwards. When there is a need to remove the driving motor, it can be accomplished by unfastening the fastening elements on the connection board. Operation is simple and fast.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
Please refer to
The tenoner of the invention also includes a connection board 14 located on a rear side of the moving dock 12. The screw bars 123 have respectively a distal end fastened to the bottom of the connection board 14 as shown in
The tenoner of the invention further includes a driving motor 15 which has a rotating spindle 151 in the center of the top thereof and a circular anchor ring 152 located on an upper side thereof. The spindle 151 runs through the anchor ring 152 on an upper side to be fastened to a cutter 153. The anchor ring 152 further has screw holes 154 corresponding to the apertures 142 to be fastened by fastening elements 155 (such as bolts) to the apertures 142 so that the driving motor 15 is fastened to the connection board 14.
A transverse positioning rod 16 also is provided above the chassis 11 that has a plurality of notches 161 on the front side formed in an equally spaced manner. The notches 161 are to be leaned by the guiding portion 127 of the directing rod 125 so that the directing rod 125 can be moved on the jagged surface of the positioned rod 16 to drive the moving dock 12 synchronously, meanwhile the cutter 153 is moved forwards and rearwards at the same time according to the jagged surface of the positioning rod 16 to cut the work piece simultaneously to form tenon ditches (or tenon lugs) at a constant interval.
By means of the construction set forth above, during cutting the tenon ditches on the work piece, the moving dock 12 is moved rightwards, and the directing wheel 125 at the bottom of the moving dock 12 leans on the lower side of the position rod 16. The sliding member 122 is held and drives the moving dock 12 forwards and rearwards through the directing rod 125 so that the cutter 153 is moved forwards and rearwards firmly and smoothly.
In the event that malfunction occurs to the driving motor 15 and removing is needed to do repairs, it can be accomplished by unfastening the fastening elements 155 on the top of the connection board 14 without removing the moving dock 12. Compared with the conventional technique of installing and removing the driving motor 2 shown in
Prototypes of the invention have been made and tested with desired results. The object and functions previously discussed have been achieved satisfactorily. It offers a significant improvement over the conventional techniques.
While the preferred embodiment of the invention has been set forth for the purpose of disclosure, modifications of the disclosed embodiment 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.
