Description

Technical Field

[0001] This utility model relates to the field of dial testing technology, and in particular to a testing platform for dial production. Background Technology

[0002] The impact testing of watch dials is primarily to ensure their reliability, durability, and safety in daily use or extreme environments. This is typically achieved by using a test ball in free fall. Since the weight and height of the test ball are known, the impact force upon collision can be controlled. For example, in patent publication number CN222762392U, published on April 15, 2025, entitled "A Testing Platform for Watch Dial Production," workers drop the test ball into through-holes at different heights to change the testing intensity. However, due to the varying thicknesses of different watch dial sizes and the fixed position of the measuring scale lines, the surface may show positions above or below the zero mark. This results in a significant error between the actual distance between the test ball and the dial and the measured value, affecting the accuracy of the test results. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that affect the accuracy of test results, and to propose a testing platform for dial production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a testing platform for dial production, including a protective box. The protective box is rotatably connected to a threaded rod via a bearing. A fixing lug is threaded onto the threaded rod. A scale is fixedly connected to the fixing lug. The fixing lug is limited by a limiting mechanism. A connecting lug is connected to the scale via an adjusting mechanism. A through hole is formed in the connecting lug. A sleeve is installed in the through hole. The lower end of the sleeve abuts against a support block. A rotating shaft is fixedly connected to the support block. The rotating shaft is rotatably connected to the connecting lug via a bearing. A testing ball is disposed inside the sleeve.

[0006] Preferably, a support platform is fixedly connected to the lower end of the protective box.

[0007] Preferably, the limiting mechanism includes a limiting post, which is fixedly connected to the protective box, and a limiting hole is provided on the fixing ear, with the limiting post located in the limiting hole.

[0008] Preferably, the threaded rod is provided with a rotating block.

[0009] Preferably, the adjustment mechanism includes a connecting sleeve, which is fitted onto the scale, and a bolt is threaded through the connecting sleeve, the bolt abutting against the scale.

[0010] Preferably, a telescopic rod is fixedly connected to the protective box, and a fixed plate is rotatably connected to the telescopic rod via a bearing.

[0011] Preferably, the bearing is a slewing bearing.

[0012] Preferably, the telescopic rod is an electric telescopic rod with a self-locking function.

[0013] The present invention proposes a testing platform for dial production, which has the following advantages: by rotating the threaded rod, the height of the scale can be adjusted so that the lower end of the scale abuts against the dial, so that during testing, the distance between the testing ball and the dial is equal to the distance measured by the scale line, thus ensuring the accuracy of the test results when testing dials of different thicknesses.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1: Refer to Figure 1-3 A testing platform for dial production includes a protective box 2, which serves to protect the test ball and debris from flying out.

[0020] The protective box 2 is rotatably connected to a threaded rod 10 via a bearing. A rotating block is provided on the threaded rod 10, and a fixed ear 12 is threadedly connected to the threaded rod 10. A scale 3 is fixedly connected to the fixed ear 12 and is limited by a limiting mechanism. A connecting ear 9 is connected to the scale 3 via an adjusting mechanism. A through hole is opened on the connecting ear 9, and a sleeve 5 is installed in the through hole. When testing dials of different thicknesses, the height of the scale 3 is adjusted by rotating the threaded rod 10 so that the lower end of the scale 3 abuts against the dial. This ensures that the distance between the testing ball and the dial is equal to the distance measured by the scale line during testing, thus guaranteeing the accuracy of the test results when testing dials of different thicknesses.

[0021] The lower end of the sleeve 5 abuts against a support block 8, and a rotating shaft 7 is fixedly connected to the support block 8. The rotating shaft 7 is rotatably connected to the connecting lug 9 through a bearing. A detection ball is installed inside the sleeve 5. By rotating the rotating shaft 7, the support block 8 is driven to rotate, thereby opening the lower end of the sleeve 5 and causing the detection ball to make free fall motion.

[0022] The lower end of the protective box 2 is fixedly connected to the support platform 1, which increases the height of the device so that it can be used for testing while standing.

[0023] The limiting mechanism includes a limiting post 11, which is fixedly connected to the protective box 2. A limiting hole is opened on the fixed ear 12, and the limiting post 11 is located in the limiting hole. By using the limiting post 11 to limit the fixed ear 12, the fixed ear 12 is prevented from rotating.

[0024] Example 2: Refer to Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 1, the adjustment mechanism includes a connecting sleeve 4, which is sleeved on the scale 3. A bolt 6 is threaded through the connecting sleeve 4 and abuts against the scale 3. By adjusting the position of the connecting sleeve 4 on the scale 3 and fixing the connecting sleeve 4 by tightening the bolt 6, the height of the detection ball can be adjusted.

[0025] Example 3: Reference Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 2, a telescopic rod 14 is fixedly connected to the protective box 2. A fixed plate 13 is rotatably connected to the telescopic rod 14 via a bearing, which is a slewing bearing. The telescopic rod 14 is an electric telescopic rod with a self-locking function. The telescopic rod 14 extends and retracts to abut the fixed plate 13 against the dial, fixing the dial and preventing it from moving during testing. At the same time, since the fixed plate 13 can rotate, different positions of the dial can be placed under the detection ball. By rotating the fixed plate 13, different positions of the dial are abutted and fixed.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
