Description

Technical Field

[0001] This utility model relates to the field of jewelry processing technology, and in particular to a jewelry processing clamping fixture. Background Technology

[0002] Christmas is a major holiday, and to create a festive atmosphere, every household buys a Christmas tree and places various decorations on it.

[0003] In the current technology, the decorations on Christmas trees need to be positioned during processing. However, due to the wide variety and different shapes of Christmas decorations, some clamping fixtures can only position decorations of a single shape, which has certain limitations and needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the existing technology: when processing Christmas tree decorations, a positioning device is needed, but because Christmas decorations are of various types and shapes, some clamping fixtures can only position decorations of a single shape, which has certain limitations.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a jewelry processing clamping fixture, comprising: a worktable; a slot formed on the surface of the center of the worktable; and further comprising:

[0006] Two mounting brackets are provided on the inner wall at the symmetrical location of the slot, and a guide rod is fixedly installed on the inner wall of one of the mounting brackets;

[0007] A movable plate is movably fitted onto the surface of the mounting frame, and a threaded rod is threaded into one end of the movable plate;

[0008] A load-bearing base is disposed on the surface at the center of the workbench.

[0009] Preferably, a limiting groove is formed on the surface of the movable plate, and a U-shaped frame is provided on one side surface of the movable plate.

[0010] The technical effect of adopting the above-mentioned further solution is that the limiting groove opened on the surface of the movable plate facilitates the limiting of internal parts, while providing a fixing function for the U-shaped frame.

[0011] Preferably, a drive motor is provided on one inner wall of the U-shaped frame, and a bidirectional lead screw is provided at the output end of the drive motor.

[0012] The technical effect of adopting the above-mentioned further solution is that the drive motor on the surface of the U-shaped frame provides a fixed working function for the bidirectional lead screw.

[0013] Preferably, the surface of the bidirectional lead screw at the symmetrical position is threaded with a limiting block, and the two limiting blocks are slidably embedded in the limiting groove.

[0014] The technical effect of adopting the above-mentioned further solution is that when the bidirectional lead screw rotates, it drives the limiting block on the symmetrical surface to move along the inside of the limiting groove for centering.

[0015] Preferably, the surfaces of the two limiting blocks opposite each other are provided with connecting shafts, and one end of the two connecting shafts is provided with a mounting base.

[0016] The technical effect of adopting the above-mentioned further solution is that when the limit block moves, the mounting base is driven to perform centering movement by means of the connecting shaft on the surface, thereby completing the clamping and positioning work.

[0017] Preferably, the inner walls of the two mounting bases are provided with limiting holes, and springs are fixedly installed on the inner walls of the plurality of limiting holes.

[0018] The technical effect of adopting the above-mentioned further solution is that the spring is fixed by the limiting hole opened inside the mounting base.

[0019] Preferably, one end of each of the multiple springs is provided with a limiting disc, and the multiple limiting discs are slidably embedded inside the limiting hole.

[0020] The technical effect of adopting the above-mentioned further solution is that the spring provides displacement and reset capability to the limiting disc, while the limiting hole limits the limiting disc to prevent it from slipping.

[0021] Preferably, a positioning shaft is provided on one side surface of the plurality of limiting discs, and a protective pad is provided at one end of the plurality of positioning shafts.

[0022] The technical effect of adopting the above-mentioned further solution is that when the limiting disc moves, it causes the protective pad on the surface of the positioning shaft to come into contact with the ornament, thereby performing the positioning work.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] 1. In this utility model, before operation, by rotating the threaded rod inside the mounting bracket, the moving plate on the outer surface is driven to adjust its position along the guide rod, thereby fixing the protective pad on the positioning shaft surface and the ornament in the center position, enhancing stability and preventing displacement during processing.

[0025] 2. In this utility model, by placing Christmas ornaments on the surface of the support base and starting the drive motor, the bidirectional lead screw on the output end surface drives the limiting block to move in a centered position. At the same time, the limiting groove provides a limiting function for the limiting block. When the two limiting blocks move in a centered position, they work together with the connecting shaft to drive the mounting base to move closer to each other. When the protective pad on the surface of the positioning shaft contacts the ornament, the two ends of the spring are respectively connected to the surface of the limiting hole and the limiting disc, which facilitates the movement of the limiting disc on the surface of the positioning shaft inside the limiting hole. This completes the positioning work for ornaments of different shapes and improves the applicability of the device. Attached Figure Description

[0037] In this embodiment, by placing Christmas ornaments on the surface of the support base 102, the drive motor 2021 is started, and the bidirectional lead screw 2022 on the output end surface drives the limiting block 2023 to move in a centered position. At the same time, the limiting groove 201 provides a limiting function for the limiting block 2023. When the two limiting blocks 2023 move in a centered position, the connecting shaft 2024 drives the mounting base 2025 to move closer to each other. When the protective pad 203 on the surface of the positioning shaft 2029 contacts the ornament, the two ends of the spring 2027 are respectively connected to the surface of the limiting hole 2026 and the limiting disc 2028, which facilitates the movement of the limiting disc 2028 on the surface of the positioning shaft 2029 inside the limiting hole 2026, thereby completing the positioning work for ornaments of different shapes and improving the applicability of the device.

[0038] Working principle: In use, the Christmas ornament is placed on the surface of the support base 102, and the drive motor 2021 is started. The bidirectional lead screw 2022 on the output end surface drives the limiting block 2023 to move in a centered position. At the same time, the limiting groove 201 provides a limiting function for the limiting block 2023. When the two limiting blocks 2023 move in a centered position, they cooperate with the connecting shaft 2024 to drive the mounting base 2025 to move closer to each other. When the protective pad 203 on the surface of the positioning shaft 2029 contacts the ornament, the two ends of the spring 2027 are respectively connected to the limiting hole 2026 and the... The limiting disc 2028 on the surface of the positioning shaft 2029 facilitates the movement of the limiting disc 2028 within the limiting hole 2026, thereby completing the positioning work for ornaments of different shapes and improving the applicability of the device. In addition, before operation, by rotating the threaded rod 1013 inside the mounting bracket 1011, the moving plate 2 on the outer surface is driven to adjust its position along the guide rod 1012, thereby fixing the protective pad 203 on the surface of the positioning shaft 2029 in the center position with the ornament, enhancing stability and preventing displacement during processing.
