Description

Technical Field

[0001] This utility model relates to the field of watch case clamping equipment, specifically a clamping device for watch case processing. Background Technology

[0002] During the processing of watch cases, the watch cases need to be clamped and fixed. Traditional watch case clamping only has two forms: internal support and external clamping. Both are clamped on the watch case body. All the tension and clamping forces are applied to the watch case body. The pressure generated by the clamping tool can easily cause the watch case to deform.

[0003] According to the watch case clamp disclosed in patent document CN222627459U, it includes a first support member and a second support member. The first support member is mounted on the second support member and forms a clamping position between them. The clamping position is used to accommodate the watch case. The watch case is sleeved on the first support member. In a first direction, the first support member is used to abut against a first end of the watch case, and the second support member is used to abut against a second end of the watch case. In use, this technical solution increases the contact area between the watch case and the first support member by supporting the watch case with the first support member and sleeved on the first support member. This avoids the use of internal support and external clamping to fix the watch case, reducing the tensile force and clamping force on the watch case and reducing the local stress on the outer surface of the watch case. However, although this technical solution reduces the stress on the surface of the case, it cannot quickly clamp and fix the watch case according to its diameter, which is inconvenient in use. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a jig for watch case processing, thereby solving the problems mentioned in the background art. This utility model has a novel structure. In use, the watch case is placed between fixed columns. As the movable seat moves, the movable seat applies pressure to the watch case. Under pressure, the fixed columns move around the watch case. When the fixed columns move to the lugs, they are limited and fixed. Then, the movable seat squeezes the fixed columns to complete the clamping and fixing of the watch case.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a jig for processing watch cases, comprising a base, a fixed seat welded onto the base, a movable seat movably mounted on one side of the fixed seat, openings on both the movable seat and the fixed seat, an arc-shaped groove on the inner wall of the opening, an arc-shaped block movably mounted inside the arc-shaped groove, the arc-shaped block being mounted inside the arc-shaped groove by a support mechanism, a ring seat fixed to one end of the arc-shaped block, a fixed column rotatably mounted inside the ring seat, and a housing movably mounted between the fixed columns.

[0006] Furthermore, a lug is fixed to the housing, a fixing post is movably installed on one side of the lug, and a threaded rod is fixed to the fixing post.

[0007] Furthermore, a compression seat is rotatably mounted on the threaded rod, the compression seat is movably mounted on the top of the housing, and a buffer pad is fixed to the bottom of the compression seat.

[0008] Furthermore, an adjusting screw is rotatably mounted on the base, and a support plate is rotatably mounted on the top of the adjusting screw, with the support plate movably mounted on the bottom of the housing.

[0009] Furthermore, the base has a groove, and a slider is movably installed inside the groove, with one end of the slider fixed to the bottom of the movable seat.

[0010] Furthermore, a support block is fixed to the bottom of the base, and the adjusting screw is movably installed between the support blocks.

[0011] Furthermore, a bearing seat is fixed to one side of the movable seat, a threaded post is installed on the bearing seat, and a threaded seat is installed on the threaded post.

[0012] Furthermore, the threaded seat is fixed on the base, and the threaded seat has a threaded hole, with the threaded post rotatably installed inside the threaded hole.

[0013] The beneficial effects of this utility model are:

[0014] 1. A jig for processing watch cases, wherein the watch case is placed between fixed columns during use. As the movable seat moves, the movable seat applies pressure to the watch case. Under pressure, the fixed columns move around the watch case. When the fixed columns move to the lugs, they are limited and fixed. Then, the movable seat squeezes the fixed columns to complete the clamping and fixing of the watch case.

[0015] 2. This type of fixture for processing watch cases involves a pressing seat rotating on a threaded rod. The pressing seat contacts the top of the watch case during rotation, thereby limiting the upper and lower positions of the watch case. In addition, before the watch case is installed, a support plate moves upward to support and fix the bottom of the watch case, thus achieving multi-point fixation and avoiding the impact of watch case movement during processing.

[0016] 3. In this type of fixture for processing watch cases, after the threaded column drives the movable seat to move, the support plate provides support for the case. After the case is no longer compressed, the fixed column returns to its original position under the tension of the support mechanism, and the case can be easily and quickly removed from the support plate.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a jig for processing watch cases, including a base 1, a fixed seat 3 welded on the base 1, a movable seat 4 movably installed on one side of the fixed seat 3, an opening 8 on both the movable seat 4 and the fixed seat 3, an arc-shaped groove 9 on the inner wall of the opening 8, an arc-shaped block 18 movably installed inside the arc-shaped groove 9, the arc-shaped block 18 being installed inside the arc-shaped groove 9 by a support mechanism 19, a ring seat 10 fixed to one end of the arc-shaped block 18, a fixed column 11 rotatably installed inside the ring seat 10, a housing 20 movably installed between the fixed columns 11, a watch lug 21 fixed on the housing 20, the fixed column 11 movably installed on one side of the watch lug 21, a threaded rod 12 fixed on the fixed column 11, and a support spring 19, which pushes the arc-shaped block 18 to move, thereby facilitating the later return of the fixed column 11 to its original position.

[0024] In this embodiment, a pressing seat 13 is rotatably mounted on the threaded rod 12. The pressing seat 13 is movably mounted on the top of the housing 20. A buffer pad is fixed at the bottom of the pressing seat 13. An adjusting screw 17 is rotatably mounted on the base 1. A support plate 16 is rotatably mounted on the top of the adjusting screw 17. The support plate 16 is movably mounted on the bottom of the housing 20. A sliding groove 14 is opened on the base 1. A slider 15 is movably mounted inside the sliding groove 14. One end of the slider 15 is fixed to the bottom of the movable seat 4. The support plate 16 is adjusted in height under the support of the adjusting screw 17 to support housings 20 of different thicknesses.

[0025] In this embodiment, a support block 2 is fixed to the bottom of the base 1, and an adjusting screw 17 is movably installed between the support blocks 2. A bearing seat 5 is fixed to one side of the movable seat 4, and a threaded post 7 is installed on the bearing seat 5. A threaded seat 6 is installed on the threaded post 7, and the threaded seat 6 is fixed to the base 1. A threaded hole is opened on the threaded seat 6, and the threaded post 7 is rotatably installed inside the threaded hole. The threaded post 7 rotates and moves inside the threaded hole, and the movement of the threaded post 7 pushes the movable seat 4. The movable seat 4 is pushed and squeezes the housing 20.

[0026] When using this device, first rotate the adjusting screw 17. The adjusting screw 17 pushes the support plate 16 up and down. The support plate 16 adjusts its position according to the thickness of the housing 20. After the position of the support plate 16 is adjusted, it supports the housing 20, so that the lugs 21 of the housing 20 protrude from the fixed seat 3 and the movable seat 4. Press the housing 20 onto the support plate 16. Rotate the threaded column 7 to push the movable seat 4 to move. When the movable seat 4 moves, the fixed column 11 contacts both sides of the housing 20. As the pressing force increases, the fixed column 11 passes through the ring seat 10 on the housing 20. The side of the 0 rotates and moves, and the fixed column 11 moves around the housing 20. When the fixed column 11 moves to the lug 21 and stops moving, the movable seat 4 moves again. The fixed column 11 clamps and fixes the lug 21 under the limit, thereby realizing the limit fixation of the housing 20. After the housing 20 is limited, the extrusion seat 13 is rotated and moves on the threaded rod 12. By rotating and descending, it contacts the top of the housing 20. The extrusion seat 13 realizes the upper and lower limit of the housing 20, thereby completing the multi-point clamping and fixing of the housing 20.
