Description

Technical Field

[0001] The utility model relates to the technical field of watch middle frame detection, and more specifically, to a jig for watch middle frame detection. Background Technique

[0002] A watch itself is a precision and complex mechanical device. Coupled with various watches launched on the market nowadays, which have multiple functions such as waterproofing and explosion protection. Therefore, for the manufacturing and processing of watches, especially the manufacturing of sports watches, in order to ensure the waterproof performance of the button positions on the watch frame, a series of airtightness detections need to be carried out after manufacturing and assembly to ensure the qualified manufacturing and assembly of the watch frame and buttons.

[0003] The watch middle frame is usually initially formed by casting, and then the watch middle frame is finely trimmed through processes such as grinding. However, during the casting process, if the cooling is improper, cracks will appear inside the watch middle frame, resulting in defective products of the watch middle frame and affecting the product qualification rate. Therefore, after the watch middle frame is produced, it will be subjected to crack detection. Usually, the watch middle frame is detected by oscillation. However, the existing detection instruments can only oscillate the same position of the watch middle frame. When changing the oscillation position, it is necessary to re-dismantle and fix the watch middle frame, resulting in a reduction in the detection efficiency of the watch middle frame.

[0004] In view of this, we propose a jig for watch middle frame detection. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a jig for watch middle frame detection to solve the technical problem that it is necessary to re-dismantle and install when detecting different positions of the watch middle frame currently.

[0006] To solve the above technical problem, the utility model provides the following technical solution: A jig for watch middle frame detection, including a bottom plate and a detection mechanism installed on the bottom plate. The detection mechanism includes a vibration mechanism facing the center position of the bottom plate. An adjustment mechanism is installed at the center position of the bottom plate. The adjustment mechanism includes a workbench. A clamping mechanism with a changeable position is installed at the center position of the upper end surface of the workbench. An I-shaped clamp block is installed at the bottom end of the clamping mechanism;

The two sliding blocks are jointly rotatably connected to a first threaded rod. A positioning block is spirally connected to the middle of the first threaded rod. A connecting rod connecting the clamp block is installed at the top end of the positioning block.

A through groove is provided in the workbench, the diameter of the through groove is larger than the diameter of the cylinder formed by the clamping blocks, and the diameter of the through groove is smaller than the diameter of the circular plates formed by the clamping blocks.

[0009] Preferably, a plurality of rollable spheres are fitted and installed at both the upper and lower ends of the workbench. The spheres installed at the upper and lower ends of the workbench respectively abut against the adjacent sides of the circular plates of the clamping blocks to reduce friction.

The detection mechanism 2 includes a vibration mechanism 201 facing the center position of the base plate 1. An adjustment mechanism 3 is installed at the center position of the base plate 1. The adjustment mechanism 3 includes a workbench 301. A clamping mechanism 4 with a changeable position is installed at the center position of the upper end surface of the workbench 301. A work-shaped clamping block 401 is installed at the bottom end of the clamping mechanism 4;

[0023] Two slide bars 5 are symmetrically installed at the bottom end of the workbench 301. Slide blocks 501 are slidably installed on the two slide bars 5. The two slide blocks 5 are jointly rotatably connected to a first threaded rod 6. A positioning block 601 is screwed in the middle of the first threaded rod 6. A connecting rod 602 connecting the clamping block 401 is installed at the top end of the positioning block 601.

[0024] In the embodiment of the present utility model, the clamping block 401 has a structure in which a circular plate is connected to the upper and lower ends of a cylinder. A through groove 303 is opened in the workbench 301. The diameter of the through groove 303 is larger than the diameter of the cylinder formed by the clamping block 401, and the diameter of the through groove 303 is smaller than the diameter of the circular plate formed by the clamping block 401. A plurality of rollable spheres 304 are embedded and installed at both the upper and lower ends of the workbench 301. The spheres 304 installed at both the upper and lower ends of the workbench 301 respectively abut against the adjacent sides of the circular plate of the clamping block 401 to reduce friction. The clamping block 401 is installed through the through groove 303 opened in the workbench 301. A plurality of spheres 304 embedded and installed around the through groove 303 abut against the adjacent sides of the circular plate of the clamping block 401, which can reduce the friction between the workbench 301 and the clamping block 401 when moving the clamping block 401 and reduce wear;

[0025] In an embodiment of the present utility model, a second threaded rod 7 is spirally installed at the bottom end of the positioning block 601. Long plates 701 are installed at both ends of the second threaded rod 7. The two long plates 701 are respectively fixedly connected to both ends of the two sliding rods 5. Four connecting plates 302 fixedly connected to both ends of the two long plates 701 are installed at the bottom end of the workbench 301. The first threaded rod 6 is placed in the upper section inside the positioning block 601, and the second threaded rod 7 is placed in the lower section inside the positioning block 601. A limiting block 702 rotatably connected to the second threaded rod 7 is installed inside the long plate 701. The limiting block 702 is slidably connected to the long plate 701. A frame for the limiting block 702 to slide is provided in the middle of the long plate 701. The limiting block 702 moves synchronously with the first threaded rod 6. By rotating the first threaded rod 6, the positioning block 601 and the second threaded rod 7 are driven to move horizontally. By rotating the second threaded rod 7, the first threaded rod 6 and the positioning block 601 are driven to move vertically. Thus, the position of the clamping mechanism 4 can be adjusted, and different positions can be detected without disassembling and reinstalling the watch middle frame, improving the detection efficiency of the watch middle frame.

[0026] Working principle: This embodiment provides a fixture for detecting a watch middle frame. When in use, the watch middle frame is fixed by the clamping mechanism 4, and then the vibration mechanism 201 on the detection mechanism 2 is used to perform oscillating detection on a position on the watch middle frame to detect whether there are cracks inside. After detecting one point, by rotating the first threaded rod 6 and the second threaded rod 7, the positioning block 601 is driven to move in the through groove 303 and can stay at any position in the through groove 303. Thus, any position of the watch middle frame can be detected, which is more convenient and does not require disassembling the watch middle frame, changing its position, and re-fixing it for detection.
