[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] like Figure 1-2As shown, this utility model is a watch strap cutting fixture for watch production, including a positioning frame. The positioning frame includes a side plate 1, a bottom plate 11, and a top plate 12. A movable groove 13 is formed in the middle of the side plate 1. A lifting mechanism is provided on the side of the side plate 1. The lifting mechanism includes a first lead screw 14 and a first guide rod 15 arranged in parallel. A lifting seat 16 is connected to the first lead screw 14 and the first guide rod 15. A first motor 17 is connected to the top of the first lead screw 14. A second lead screw is connected to the side of the lifting seat 16. 18 and 19 are connected to a second guide rod and a moving seat 2. One end of the second lead rod 18 is connected to a second motor 21. The lower side of the moving seat 2 is connected to a cutting mechanism 23 via a pull rod 22. A positioning seat 24 is provided below the cutting mechanism 23. A groove 25 is provided on the top of the positioning seat 24. Limiting seats 26 are symmetrically distributed on the outer side of the positioning seat 24. A locking screw 27 is screwed onto the limiting seat 26. One end of the locking screw 27 is connected to a clamping block 28.

[0018] The lifting seat 16 can be moved up and down by the cooperation of the first guide rod 15, the first lead screw 14 and the first motor 17. The lateral position of the moving seat 2 can be adjusted by the cooperation of the second guide rod 19, the second lead screw 18 and the second motor 21, thereby achieving the purpose of spatial adjustment of the cutting mechanism 23. This can meet different processing effects, and the operation is simple and convenient with a high degree of automation. The limiting mechanism (composed of limiting seat 26, locking screw 27 and clamping block 28) distributed on both sides of the positioning seat 24 can clamp and fix the workpiece by manually adjusting the clamping block 28, ensuring the stability during processing.

[0019] In the above solution, the side plate 1, bottom plate 11, and top plate 12 are integrally formed, and the lower surface of the bottom plate 11 is provided with anti-slip texture. The integrally formed structure enhances the overall strength and stability of the positioning frame, while the anti-slip texture on the lower surface of the bottom plate 11 increases the friction between it and the placement table, preventing the fixture from shifting during the cutting process and further ensuring the stability of the cutting.

[0020] In the above scheme, both the lifting seat 16 and the moving seat 2 are provided with threaded holes and guide holes. The threaded holes on the lifting seat 16 and the moving seat 2 respectively cooperate with the first lead screw 14 and the second lead screw 18 to realize the function of the lead screw rotating to drive the seat body to move; the guide holes cooperate with the first guide rod 15 and the second guide rod 19 to play a guiding role, ensuring the stability of the seat body during the movement process, avoiding shaking or deviation, so that the cutting mechanism 23 can be positioned more accurately and the cutting accuracy can be improved.

[0021] In the above scheme, the end of the first lead screw 14 is rotatably connected to the base plate 11 and the top plate 12 via a bearing seat. The bearing seat connection reduces the frictional force when the first lead screw 14 rotates, making the rotation of the first lead screw 14 driven by the first motor 17 smoother, reducing the motor load, improving transmission efficiency, and ensuring the stability of the rotation of the first lead screw 14, thereby ensuring the smooth and reliable lifting movement of the lifting seat 16.

[0022] In the above scheme, the second motor 21 is mounted on a motor base, which passes through the movable slot 13 and is fixedly connected to the lifting seat 16. This mounting method allows the second motor 21 to move up and down together with the lifting seat 16, and at the same time, the position of the second lead screw 18 can be adjusted by moving the motor base within the movable slot 13, thereby better cooperating with the lateral adjustment of the moving seat 2 and ensuring the flexibility and accuracy of the spatial adjustment of the entire cutting mechanism 23.

[0023] In the above scheme, a collection cover 29 is provided inside the groove 25, and a locking block 3 is provided at the bottom of the positioning seat 24, which is movably engaged in the slot on the base plate 11. The collection cover 29 is used to collect the debris generated during the cutting process, preventing debris from flying everywhere, keeping the working environment clean, and also preventing debris from affecting the cutting accuracy or causing injury to the operator. The positioning seat 24 is movably engaged with the slot on the base plate 11 by the bottom locking block 3, which facilitates the installation and removal of the positioning seat 24, makes it easy to clean or replace the collection cover 29, and allows for flexible replacement of positioning seats 24 of different specifications according to different cutting needs.

[0024] In the above scheme, both the first motor 17 and the second motor 21 are connected to a power source and a switch via wires. The power source and switch control the start, stop, and speed of the first motor 17 and the second motor 21, making operation simple and convenient. This allows operators to control the operation according to the actual cutting situation, enabling precise adjustment of the position of the cutting mechanism 23 and meeting diverse processing needs.

[0025] Working principle:

[0026] This watch strap cutting fixture for watch production first places the watch strap to be cut in the groove 25 at the top of the positioning seat 24. By rotating the locking screw 27 on the limiting seat 26, the clamping block 28 moves towards the watch strap, thereby tightly clamping and fixing the watch strap on the positioning seat 24, ensuring the stability of the watch strap during the cutting process and preventing it from shifting or shaking.

[0027] The first motor 17 is started, which drives the first lead screw 14 to rotate. Since the first lead screw 14 engages with the threaded hole on the lifting seat 16, and the first guide rod 15 acts as a guide, the lifting seat 16 moves up and down along the first lead screw 14 and the first guide rod 15. Based on the thickness of the watch strap and the required cutting depth, the lifting seat 16 is adjusted to a suitable height position by controlling the forward and reverse rotation and the number of rotations of the first motor 17.

[0028] Next, the second motor 21 is started, which drives the second lead screw 18 to rotate. The second lead screw 18 engages with the threaded hole on the moving seat 2, and the second guide rod 19 acts as a guide, causing the moving seat 2 to move laterally along the second lead screw 18 and the second guide rod 19. By controlling the forward and reverse rotation and the number of rotations of the second motor 21, the position of the moving seat 2 is adjusted, thereby driving the cutting mechanism 23 to move above the position to be cut on the watch strap.

[0029] Once the cutting mechanism 23 has moved to the appropriate position, it is activated (the cutting mechanism 23 can be a common electric cutting blade or laser cutting device; its specific structure and operation are existing technologies and will not be described in detail here) to cut the watch strap. During the cutting process, the limiting mechanism on the positioning seat 24 continuously clamps and fixes the watch strap to ensure the accuracy of the cut.

[0030] After cutting, reverse the operation of the first motor 17 and the second motor 21 to return the cutting mechanism 23 to its initial position. Loosen the locking screw 27, remove the cut watch strap, and complete one cutting operation. To continue cutting other watch straps, repeat the above steps. Meanwhile, during the entire cutting process, the collection cover 29 in the groove 25 collects the cutting debris. When there is a large amount of debris in the collection cover 29, the positioning base 24 can be removed from the slot in the base plate 11 by removing the locking block 3 at the bottom of the positioning base 24, and the collection cover 29 can be cleaned.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
