Description

Technical Field

[0001] This utility model relates to the field of watch strap processing, and in particular to a fixture for watch strap processing. Background Technology

[0002] In the processing of stainless steel watch bands, traditional clamp designs mainly focus on firmly clamping the watch band to ensure the smooth progress of subsequent processing steps such as grinding and polishing; however, this traditional clamp design has obvious limitations, especially when dealing with watch bands that require a specific curvature or arch to meet design requirements.

[0003] Specifically, in order to meet consumers' requirements for the appearance and wearing comfort of watches, stainless steel watch bands often need to be slightly adjusted in shape during the processing according to design requirements; for example, in some designs, the watch band needs to have a specific curvature or arch to better fit the contour of the wrist and improve wearing comfort and aesthetics; however, traditional clamp designs lack the necessary adjustment mechanisms and cannot effectively adapt to such changes in shape.

[0004] In addition, traditional clamps usually use a relatively rigid fixing method when fixing watch straps. While this method can ensure the stability of the watch strap during processing, it may also cause the watch strap to deform or be damaged under uneven stress. Especially when polishing watch straps with specific curvature or arches, traditional clamps often fail to provide sufficient support and adjustment space, making it difficult to achieve the desired processing results.

[0005] Therefore, it is necessary to provide a new fixture for processing watch straps to solve the above-mentioned technical problems. Utility Model Content

The first guide rod 85 is used to fix the placement plate 4, and the second guide rod 99 is used to arch the watch strap. The polishing rollers located at the second guide rod 99 are at different heights.

[0034] The working principle of the jig for processing watch straps provided by this utility model is as follows:

[0035] Clamping and conveying:

[0036] The watch strap is placed on the placement plate 4 and initially secured by the fixing rod 5 and the movable moving rod 6.

[0037] The conveyor belt 1, through its movement, drives the watch straps on the mounting base 3 and the placement plate 4 to move along the grinding rollers that are equidistantly installed inside the processing frame 2, for continuous processing.

[0038] Working principle of fixed structure:

[0039] When the placement plate 4 moves to the vicinity of the first guide rod 85 along with the conveyor belt 1, the L-shaped push rod 83 contacts the inclined surface of the first guide rod 85. Due to the inclined surface design, the L-shaped push rod 83 is pushed and the tension spring 84 is stretched.

[0040] The movement of the L-shaped push rod 83 causes the rack 82 connected to it to move. Since both racks 82 are meshed with the gear 81, the other rack 82 will also move synchronously.

[0041] The moving ends of the two racks 82 are respectively engaged in the slots 86 at the bottom of the placement disk 4, thereby fixing the placement disk 4.

[0042] Working principle of arched structure:

[0043] Once the watch strap is secured, the conveyor belt 1 continues to move, at which point the second guide rod 99 contacts the inclined surface of the trapezoidal top block 92.

[0044] Due to the inclined design of the trapezoidal top block 92, it is pressed to one side by the second guide rod 99, and at the same time, it presses the connecting block 91 connected to it.

[0045] The movement of connecting block 91 causes the spring piece 7 to deform, thereby arching the middle of the watch band.

[0046] The deformation of spring 7 not only helps the watch band form the required arch, but also ensures the stability and even stress distribution of the watch band during the polishing process.

[0047] The return spring 93 connecting the trapezoidal top block 92 and the placement plate 4 deforms when the trapezoidal top block 92 moves. After the second guide rod 99 passes the trapezoidal top block 92, the return spring 93 returns to its original state, pushing the trapezoidal top block 92 and the connecting block 91 back to the initial position, preparing for the processing of the next watch strap.

[0048] Processing and shape adjustment:

[0049] Driven by the conveyor belt 1, the watch strap is polished by grinding rollers installed at equal intervals.

[0050] Thanks to the arch structure 9, the watch strap can maintain the required curvature or arch during polishing, especially at the joints where polishing is more even.

[0051] Meanwhile, by adjusting the positions of the threaded rod 95 and the moving rod 6, the shape of the watch strap can be further fine-tuned to meet different design requirements.

[0052] Disassembly and replacement:

[0053] After processing, the placement tray 4 can be easily removed from the conveyor belt 1 by reversing the operation of the rack 82 and L-shaped push rod 83 in the fixing structure 8.

[0054] A cover plate 10 is rotatably connected to one side of the placement plate 4 and is fixedly connected to the placement plate 4 by bolts, which facilitates the disassembly and replacement of the watch strap.

[0055] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
