Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically a positioning device for processing tenon grooves in wooden boards. Background Technology

[0002] In wood processing, it is generally necessary to mortise and tenon the wood. Mortise and tenon machines are usually used for this purpose. A mortise and tenon machine is a woodworking machine tool that processes the tenon (yang) of wood products. There are two types of mortise and tenon machines: straight tenon machines and dovetail tenon machines. The former is further divided into single-head and double-head types, while the latter is divided into vertical and horizontal types. Before being processed into boards, wood is usually cylindrical. Therefore, when processing boards, it is necessary to position and fix the cylindrical wood before processing it into boards.

[0003] A search revealed a tenoning device for processing round wood with Chinese announcement number CN221475529U. By setting up a lifting mechanism, the device can effectively clamp and fix the round wood placed in the V-shaped groove in the arc-shaped positioning groove at the bottom of the top processing platform when processing round wood. This effectively solves the defect in the prior art that it is impossible to accurately and stably position round wood.

[0004] However, the internal range of the V-groove set by this device cannot be adjusted. When processing small pieces of wood, it cannot be effectively fixed, and the wood will wobble inside the V-groove, making it impractical. Therefore, a positioning device for processing mortise and tenon joints of wooden boards is proposed to solve the above problems. Utility Model Content

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for processing tenon grooves in wooden boards, comprising a bottom processing platform, a top processing platform provided on the top of the bottom processing platform, rectangular grooves provided on both the left and right sides of the bottom processing platform, a first hydraulic rod installed inside the rectangular groove, a groove provided on the top wall of the bottom processing platform, an adjustment mechanism provided in the groove, and a positioning block fixedly installed on the bottom of the top processing platform;

[0009] The adjustment mechanism includes a cavity. The bottom processing platform has a cavity inside. A motor is fixedly installed on the inner bottom wall of the cavity. A rotating rod is fixedly installed at the output shaft of the motor. A bidirectional lead screw is rotatably connected inside the cavity. Two threaded sleeves are threadedly connected to the external thread of the bidirectional lead screw. A driving gear is fixedly installed on the external thread of the rotating rod. A driven gear is fixedly installed in the middle of the bidirectional lead screw. A connecting rod is fixedly installed on the top of the threaded sleeve. An adjustment plate is fixedly installed on the end of the connecting rod away from the threaded sleeve.

[0010] Furthermore, the groove is inverted trapezoidal, the adjusting plate is inclined, and an arc-shaped positioning groove is fixedly installed at the bottom of the positioning block.

[0011] Furthermore, two symmetrical mounting slots are formed on the upper surface of the top processing platform. A second hydraulic rod is fixedly installed inside the mounting slot, and a connecting plate is fixedly installed at the free end of the second hydraulic rod.

[0012] Furthermore, a mounting plate is fixedly installed on the side end of the connecting plate, an electric telescopic rod is fixedly installed on the side end of the mounting plate, a processing motor is fixedly installed on the free end of the electric telescopic rod, and a processing drill bit is fixedly installed on the output shaft end of the processing motor.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] This positioning device for mortise and tenon joint processing of wooden boards, by setting an adjustment mechanism, changes the V-shaped placement groove to a larger trapezoidal groove, which can accommodate wood of various sizes. At the same time, by controlling the motor to drive the bidirectional lead screw to rotate, it causes the two adjustment plates to move towards each other or away from each other, thereby changing the distance between the two adjustment plates so that the two adjustment plates can be adapted to the size of the wood, fixing the two sides of the wood and preventing the wood from shaking inside and affecting processing. It is highly practical. Moreover, the two adjustment plates are set at an angle, so that the wood can be stuck between the two adjustment plates, which has strong stability.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A positioning device for processing mortise and tenon joints in this embodiment includes a bottom processing platform 1, a top processing platform 2 on the top of the bottom processing platform 1, rectangular grooves 3 on both the left and right sides of the bottom processing platform 1, a first hydraulic rod 4 installed inside the rectangular grooves 3, a groove 5 on the top wall of the bottom processing platform 1, an adjustment mechanism 6 installed inside the groove 5, and a positioning block 9 fixedly installed at the bottom of the top processing platform 2.

[0025] Specifically, the adjustment mechanism 6 includes a cavity 601. The bottom processing platform 1 has a cavity 601 inside. A motor 602 is fixedly installed on the inner bottom wall of the cavity 601. A rotating rod 603 is fixedly installed at the output shaft of the motor 602. A double-acting lead screw 604 is rotatably connected inside the cavity 601. Two threaded sleeves 605 are threadedly connected to the outside of the double-acting lead screw 604. A driving gear 606 is fixedly installed on the outside of the rotating rod 603. A driven gear 607 is fixedly installed in the middle of the double-acting lead screw 604. A connecting rod 608 is fixedly installed on the top of the threaded sleeves 605. The connecting rod 608 is further... An adjusting plate 609 is fixedly installed at one end of the threaded sleeve 605. By controlling the motor 602, the rotating rod 603 and the driving gear 606 are rotated, which in turn drives the driven gear 607 and the double-acting screw 604 to rotate. The two threaded sleeves 605 move simultaneously to change the distance between the two adjusting plates 609, so that the distance between the two adjusting plates 609 is adapted to the size of the wood. This solves the problem that the internal range of the V-groove set by the proportional device cannot be adjusted, and when processing small pieces of wood, it cannot be effectively fixed, and the wood will shake inside the V-groove, resulting in poor practicality.

[0026] Specifically, the groove 5 is set in an inverted trapezoidal shape, the adjusting plate 609 is set at an angle, the bottom of the positioning block 9 is fixedly installed with an arc-shaped positioning groove, and the two adjusting plates 609 are set at an angle, so that the wood can be stuck between the two adjusting plates 609, which has strong stability. The arc-shaped positioning groove is more in line with the shape of cylindrical wood.

[0027] Specifically, a mounting plate 10 is fixedly installed on the side of the connecting plate 8, an electric telescopic rod 11 is fixedly installed on the side of the mounting plate 10, a processing motor 12 is fixedly installed on the free end of the electric telescopic rod 11, and a processing drill bit 13 is fixedly installed on the output shaft end of the processing motor 12. The processing motor 12 is controlled to drive the processing drill bit 13 to process the wood, and the electric telescopic rod 11 is controlled to drive the processing drill bit 13 to move. The second hydraulic rod 7 can adjust the processing height of the processing drill bit 12.

[0028] When implementing this procedure, please follow these steps:

[0029] 1) First, according to the size of the wood, control the motor 602 to drive the rotating rod 603 and the active gear 606 to rotate, and drive the passive gear 607 and the double-acting screw 604 to rotate. The two threaded sleeves 605 move at the same time, so that the distance between the two adjusting plates 609 is adapted to the size of the wood.

[0030] 2) Then place the wood between the two adjusting plates 609 so that the wood can be stuck between the two adjusting plates 609. Then control the first hydraulic rod 4 to drive the top processing platform 2 to move downward, so that the positioning block 9 moves downward to fix the top of the wood.

[0031] 3) Finally, control the processing motor 12 to drive the processing drill bit 13 to process the wood, and control the electric telescopic rod 11 to drive the processing drill bit 13 to move. The second hydraulic rod 7 can adjust the processing height of the processing drill bit 12.

[0032] In summary, this positioning device for processing mortise and tenon joints in wooden boards, by setting an adjustment mechanism 6, replaces the V-shaped placement groove with a larger trapezoidal groove 5, which can accommodate wood of various sizes. Simultaneously, by controlling the motor 602 to drive the bidirectional lead screw 604 to rotate, it causes the two adjustment plates 609 to move towards or away from each other, changing the distance between the two adjustment plates 609. This allows the two adjustment plates 609 to adapt to the size of the wood, fixing the sides of the wood and preventing it from shaking inside, thus affecting processing. It is highly practical. Furthermore, the two adjustment plates 609 are inclined, allowing the wood to be held between them, providing strong stability. This solves the problem of the proportional device's inability to adjust the internal range of the V-shaped groove, which makes it difficult to effectively fix smaller pieces of wood, causing the wood to shake inside the V-shaped groove and resulting in poor practicality.
