Description

TENONER MACHINE WITH SETTING FUNCTION

FIELD OF THE INVENTION

The present invention is related to woodworking machinery, and more particularly to a tenoner machine which can accurately adjust the protruded height of the cutter for lathing a groove with predetermined depth, can adjust the relative position between guiding board and object, and can set the moving stroke of the cutter.

BACKGROUND OF THE INVENTION

The conventional woodworking tenoner machine, as shown in Figs. 1 and 2, includes a machine base I with a driving motor 2 mounted at the bottom thereof, wherein the mandrel at the top of the driving motor 2 is assembled with a cutter 2a for moving with a mechanical board 2b, and through a guiding pillar 2c on the mechanical board 2b moving along the undulated edge of a guiding board 3, the cutter 2a can be guided to lathe the groove on the bottom of the object a, which is erected on the guiding board 3.

Moreover, a guiding shaft 4 with undulated edge is mounted in front of the machine base 1 for rejecting to a guiding wheel at the rear end of a moving shaft 5, which moves laterally. The middle portion of the moving shaft 5 penetrates through a vertical front wall of a moving cover 5a. Two parallel bolts 6 penetrate through the front and the rear walls of the moving cover Sa and a sliding block 7, and the rear ends of the bolts 6 are further locked with the mechanical board 2b. The bottom portion of the sliding block 7 is also penetrated by two sliding shafts 8, which are located in front of the machine base 1 in a lateral direction. The rear end of the moving cover 5a is locked with the mechanical board 2b.

Therefore, when moving forward and backward the moving cover 5a, the mechanical board 2b can be pushed forward and backward, and the driving motor 2 can move with the mechanical board 2b and also the cutter 2a on the top of the driving motor 2 can be synchronously moved. Furthermore, when pulling forward the moving cover 5a and the moving shaft 5, the guiding wheel at the rear end of the moving shaft 5 can come off the undulated edge of the guiding shaft 4, so that the moving cover 5a can have a lateral movement for repositioning, thereby the cutter 2a can move back for lathing next object.

When operation, since the object a might lath the grooves with different depths, the protruded height of the cutter 2a from the guiding board 3 should be varied. Further, because the cutter 2a is directly fixed on the driving motor 2, the difference should be achieved by adjusting the position of the driving motor 2.

However, since the conventional tenoner machine does not have any indication for the user to recognize the adjusting distance of the cutter 2a, it is difficult to ensure that the adjusted distance is identical to the predetermined groove depth.

Furthermore, the object a is installed on the machine base 1 and the guiding board 3 has to move to approach the bottom portion of the object a for forming the groove, but the conventional woodworking tenoner machine does not provide any ruler or indication as movement reference.

Besides, the width of groove of each object a might also be different, so that the forward and backward moving stroke of the cutter 2a might also be varied. However, the conventional woodworking machinery does not provide any installation for controlling the moving forward and backward distance of the cutter 2a.

SUMMARY OF THE INVENTION

Therefore, the object of the present invention is to provide a tenoner machine with setting function to solve the problems mentioned above, wherein through providing a cutter measuring unit mounted at the upper portion of the machine base to measure the protruded height of the cutter from the guiding board, and the upward and downward movements of the motor can be adjusted according thereto, so that the groove, lathed by the cutter, at the bottom of the erected object can have an accurate and desired depth.

Moreover, the present invention also provides a position measuring unit mounted on the left side and the right side mechanical walls of the machine base which can adjust the relative position between the guiding board and the object and further set the moving stroke of the cutter, so that the width of the groove can be precisely controlled.

For achieving the object described above, the present invention provides a tenoner machine with setting function including a machine base having a guiding board mounted at the top thereof, and a motor with a cutter mounted at the top thereof. The cutter moves along indentation on the guiding board so as to lathe the groove on the object, which is located on the guiding board. A cutter measuring unit is mounted at the top of the machine base and includes a through shaft with a pressing board located at the bottom thereof and a flat board mounted at the top thereof, and the flat board is directed toward a scale so as to measure the protruded height of the cutter from the guiding board. Moreover, a position measuring unit is located on a pair of mechanical walls at the left and the right sides of the machine base including a movable block connected to the guiding board, and a screw shaft locked to the movable block and penetrating another block, wherein through adjusting two adjusting nuts on the screw shaft, the screw shaft can be pulled to drive the movable block to move, so as to move the guiding board to approach the object, and the needle on the movable block which directs to the scale on the mechanical wall, can disclose the exact moving numbers. Furthermore, on the machine base, a guiding device is mounted which can have forward and backward movements for driving the motor to move along the guiding board, so that the cutter at the top of the motor can lathe the groove on the object, wherein the guiding device has a cutter feed/retract setting unit including a guiding shaft, which penetrates a vernier seat, and on the top of the vernier seat, a needle is directed to a scale on the guiding device. The front and back ends of the guiding shaft are respectively sleeved by a sliding sleeve, and through adjusting the two sliding sleeves, the moving forward and backward distance of the motor can be controlled, and also, the needle points out the moving scale.

Thereby, through the cutter measuring unit measuring the position of the cutter, the operator can realize the position of the power source, the motor, so as to set the protruded height of the cutter from the guiding board for lathing the groove with accurate depth. Moreover, through the position measuring unit at the outsides of two mechanical walls, the relative position between the guiding board and the object can be adjusted. Furthermore, through the stroke setting unit, the moving forward and backward stroke of the motor can be set and also indicated by the needle on the scale, so that the width of the groove can be precisely controlled.

Therefore, the present invention is advantageous that: 1. The machine base has cutter measuring unit mounted thereon for directly measuring the protruded height of the cutter from the guiding board, so that an accurate data reference can be provided for adjusting the position of the motor, and thus, the cutter can lathe the groove with precise depth.

2. Through adjusting two adjusting nuts on the screw shaft in the position measuring unit, the screw shaft can be pulled to drive the movable block to move, so as to move the guiding board to approach the cutter and thus adjusting the relative position between the guiding board and the object, and through the needle on the movable block directing to the scale on the mechanical wall, the exact moving distance can be realized.

3. The cutter feed/retract setting unit mounted at one side of the guiding device can set the forward and backward moving stroke of the cutter, so that the width of the lathed groove can be controlled.

When pulling up the pull stick 35, the mechanical board 12 will be driven to move backward so as to feed the cutter 135. And, through the elastic rejection of the elastic element 39, the moving shaft 36 can be pulled forward, so that the guiding wheel 361 comes off the undulated track 115. Besides, the pull stick 35 can be pulled down and moved toward the left, so that the cutter 135 can come off the indentations 111 of the guiding board 11 and reposition again for cutting next object a.

A position measuring unit 40, wherein the position measuring unit 40 is located on a pair of mechanical walls 116 at the left and the right sides of the machine base 10. A movable block 44 is mounted at the outside of each mechanical wall 116, and the inner side of the block 44 penetrates the mechanical wall 116 for connecting to the guiding board 11 so that the block 44 can move with the guiding board 11. A lug 117 is mounted at the front end of the mechanical wall"116. A screw shaft 41 is fixed to the block 44 through the rear end thereof, and the front end is penetrates through the lug 117. An adjusting nut 42 is respectively screwed at the front and the rear sides of the lug 117. A needle 43 is located at the top of the block 44 for indicating a lateral scale 11 3b on the mechanical wall 116.

A cutter feed/retract setting unit 50, wherein the setting unit 50 is assembled at the outside of the moving cover 33 and includes a leftward and rightward movable guiding shaft 51. Two ends of the guiding shaft 51 are respectively locked on the moving cover 33 through a ring. The guiding shaft 51 is sleeved by two sliding sleeves 52, and a vernier seat 53 is sleeved on the guiding shaft 52 between two sliding sleeves 52. The vernier seat 53 is a block whose lower end is locked on the sliding block 31. Besides, another scale 331 is mounted at the outside of the moving cover 33, and a needle 54 at the top of the vernier seat 53 is directed to the scale 331.

Through the structure* described above, when operation the object a is fixed on the machine base 10, the pressing board 24 under the cutter measuring unit 20 can contact with the cutter 135 for measuring the protruded height of the cutter 135 from the guiding board 11, and the flat board 23 on the through shaft 22 can indicate the scale 1 13a on the wall board 112, so that the operator can directly see the data on the scale.

Furthermore, through adjusting the position of the two sliding sleeves 52 sleeved on the screw shaft 41 in the cutter feed/retract setting unit 50, the forward and backward moving distance of the moving cover 33 on the guiding device 30 can be controlled.

Since the movement stroke of the guiding shaft 51 on the mechanical board 12 is restricted by two sliding sleeves 52, the mechanical board 12 is connected with the moving cover 33 and the motor seat 13 is fixed at the bottom of the mechanical board 12, when pulling down the pull stick 35, the mechanical board 12 can move synchronously, wherein the guiding pillar 121 at the top of the mechanical board 12 can move along the indentations of the guiding board 11 so as to guide the cutter 135 on the motor 132 to move, and the two sliding sleeves 52 can accurately restrict the stroke of the cutter 135. Besides, through the needle 54 at the top of the vernier seat 53 indicating the scale 331, the operator can actually see the moving distance. After releasing the pull stick35, the mechanical board 12 can return to the original position through the elastic element 39 on the through shaft 38.

In the aforesaid, as compared with conventional woodworking tenoner machine, the present invention is advantageous that: 1 The wall board 112 of the machine base 10 has, mounted thereon, the cutter measuring unit 20 with the pressing board 24 at the bottom thereof contacting with the cutter 135 and the flat board 23 at the top thereof indicating the scale 11 3a, so that the protruded height of the cutter can be accurately measured, and thus, the position of the motor 132 beneath the cutter 135 can be adjusted so as to accurately lathe the groove depth of the object a.

2. The pair of mechanical walls 116 at the left and the right sides of the machine base 10 has, mounted thereon, the position measuring unit 40 with two adjusting nuts 42 on the screw shaft 41, and through manually adjusting the nuts, the screw shaft 41 can be pulled to drive the movable block 44 to move, so that the relative position of the guiding board 11 and the object a can be adjusted for facilitating the lathing. Besides, through the needle 43 on the block 44 indicating the scale 1 13b on the mechanical wall 116, the exact moving distance can be realized, so that it is easy to adjust the level of the guiding board 11 through adjusting the blocks 44 at two sides.

3. The cutter feedlretract setting unit 50 mounted at one side of the guiding device 30 can set and control the forward and backward moving stroke of the motor 132 under the cutter 135, so that the cutter 135 can lathe a precise width of the groove needed by the object a. Further, the needle 54 can indicate the scale 331 for the operator.

It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the, invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
