Description

Technical Field

[0001] This utility model relates to the field of watch accessory testing technology, specifically an automated device for testing the airtightness of a watch bar. Background Technology

[0002] The adjustment mechanism on a watch is mainly used to adjust functions such as time and date. It is the core control component of the watch, and its functions, including time, date, and day of the week, can be adjusted by rotating or pushing / pulling. An airtightness test must be performed on the watch before assembly.

[0003] Currently, the airtightness testing of watch bars is primarily done manually. The watch bar is manually placed into a testing tank and rolled along the inner wall of the tank, with air bubbles observed during rolling to determine its airtightness. However, factories typically process large quantities of watch bars, making the airtightness testing process cumbersome, time-consuming, and labor-intensive, unsuitable for large-scale testing. Furthermore, manual testing cannot adjust the pressure of the watch bar in the water, limiting its applicability. Therefore, the inventor has improved the structure of the airtightness testing device. Utility Model Content

[0004] The purpose of this utility model is to provide an automated device for testing the airtightness of watch bars. This automated device has the advantages of simple structure, reasonable design, adaptability to automated testing of airtightness of watch bars of various specifications, convenient operation, simple steps, time-saving and labor-saving testing process, adaptability to large-scale airtightness testing of watch bars, and the ability to adjust the pressure of the watch bar in water. It also has a wide range of applications, which makes it easy to test the airtightness of watch bars under different pressures. This solves the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated device for testing the airtightness of a watch bar. This automated device includes a testing platform, on which a testing mechanism and a motion mechanism are arranged, located at opposite ends of the testing platform. The testing mechanism includes a testing pool, which is a hollow cavity structure with an opening at the top. A support mechanism is fixed to the motion mechanism, which includes a cylinder and a slide rail disposed on one side of the cylinder. Both the cylinder and the slide rail are fixed to the upper surface of the testing platform. The output end of the cylinder is connected to a slider, which is set on a slide rail, allowing the slider to move along the length of the slide rail. The support mechanism includes a support rod that moves with the slider. The support rod is fixed to the slider, and a crossbeam plate that can move vertically is set on the support rod. The crossbeam plate is in contact with the support rod, and a sinking rod is detachably installed at the end of the crossbeam plate away from the support rod. A fixing block and a sleeve fixed to the fixing block are set below the sinking rod. Both the fixing block and the sleeve are set in the cavity of the detection pool, and the fixing block is fixed to the lower end face of the sinking rod.

[0006] Preferably, the end of the test cell away from the slide rail is provided with a screw and a fixed seat. The screw is horizontally positioned, passes through the fixed seat and enters the interior of the test cell. The test cell is placed directly on the upper surface of the test platform, and the fixed seat is fixed to the upper surface of the test platform. The tester can rotate the screw to move the test cell horizontally, allowing it to slide on the upper surface of the test platform. This facilitates adjustment of the relative position between the watch bar and the inner wall of the test cell cavity, thus adapting to the airtightness testing of watch bars of different specifications.

[0007] Preferably, a straight groove is provided through the support rod, and an insertion hole is provided through the end of the crossbeam plate near the support rod. A first fixing plate and a second fixing plate are respectively provided at both ends of the crossbeam plate. An operating handle is fixed on the first fixing plate. The first fixing plate passes through the insertion hole in the horizontal direction and is inserted into the interior of the second fixing plate, so that the first fixing plate can contact and connect with the crossbeam plate. An opening is provided at the end of the second fixing plate near the first fixing plate to facilitate the insertion of the first fixing plate.

[0008] Preferably, a hand-tightening screw is provided at the end of the second fixed plate away from the first fixed plate. The hand-tightening screw is horizontally positioned, and its threaded end passes through the second fixed plate from the outside to the inside and contacts the support rod. When the hand-tightening screw contacts the support rod, the second fixed plate, the first fixed plate, and the crossbeam plate can be fixed at a specified height on the support rod. Therefore, by adjusting the position of the first and second fixed plates in the groove, the height of the crossbeam plate can be adjusted to more accurately immerse the watch bar in the water inside the detection mechanism cavity, and the different pressures of the watch bar in the water can be adjusted to detect the airtightness of the watch bar under different pressures.

[0023] Please see Figure 1 The present invention provides an embodiment of an automated device for testing the airtightness of a watch bar. The automated device includes a testing platform 1, on which a testing mechanism 2 and a motion mechanism 3 are provided. The testing mechanism 2 and the motion mechanism 3 are distributed at both ends of the testing platform 1. A support mechanism 4 is fixed on the motion mechanism 3. Multiple weights 5 are provided on the upper surface of the testing platform 1. The weights 5 have different weights and are evenly distributed on the testing platform 1.

[0024] Please see Figure 2The testing mechanism 2 includes a testing pool 21, which is a hollow cavity structure with an opening at the top. In actual use, sufficient water needs to be injected into the cavity of the testing pool 21. A screw 22 and a fixing seat 23 are provided at the end of the testing pool 21 away from the slide rail 32.

[0025] Please refer to it again. Figure 2 The motion mechanism 3 includes a cylinder 31 and a slide rail 32 disposed on one side of the cylinder 31. Both the cylinder 31 and the slide rail 32 are fixed to the upper end face of the detection table 1. The output end of the cylinder 31 is connected to a slider 33, which is disposed on the slide rail 32 so that the slider 33 can move in the length direction of the slide rail 32.

[0026] Please see Figure 3 The support mechanism 4 includes a support rod 41 that moves with the slider 33. A straight groove 411 is provided through the support rod 41, and the support rod 41 is fixed to the slider 33. A horizontal beam plate 42 that can move vertically is provided on the support rod 41. An insertion hole 422 is provided through the end of the horizontal beam plate 42 near the support rod 41. The horizontal beam plate 42 is in contact with the support rod 41. A sinking rod 47 is detachably installed at the end of the horizontal beam plate 42 away from the support rod 41. A fixing block 48 and a fixing rod are provided below the sinking rod 47. The sleeve 49 is fixed on the fixing block 48. Both the fixing block 48 and the sleeve 49 are set in the cavity of the detection pool 21 and immersed in water. The fixing block 48 is fixed to the lower end face of the sinking rod 47. The watch bar can be installed on the sleeve 49 by plugging it in, so that the watch bar is immersed in the water in the cavity of the detection pool 21. The operation of the cylinder 31 drives the watch bar to move horizontally, so that the watch bar rubs against the inner wall of the cavity of the detection pool 21. During the friction process, the airtightness is determined by checking whether air bubbles are generated in the water in the cavity of the detection pool 21.

[0027] Please refer to it again. Figure 3 Multiple weight holes 421 are vertically arranged at the end of the crossbeam plate 42 away from the support rod 41. The multiple weight holes 421 are arranged in a straight line, and the inner diameter of each multiple weight hole 421 is different, which is used to place weights 5 of different weights. The sinking rod 47 is fixed on the crossbeam plate 42 and suspended below the crossbeam plate 42.

[0028] Please see Figures 3 to 4The crossbeam plate 42 has a first fixing plate 43 and a second fixing plate 45 at both ends. An operating handle 44 is fixed to the first fixing plate 43. The first fixing plate 43 passes through the insertion hole 422 horizontally and is inserted into the interior of the second fixing plate 45, allowing the first fixing plate 43 to contact and connect with the crossbeam plate 42. The second fixing plate 45 has an opening at its end near the first fixing plate 43 to allow the first fixing plate 43 to be inserted. A hand-tightening screw 46 is provided at the end of the second fixing plate 45 away from the first fixing plate 43. The hand-tightening screw 46 is horizontally positioned and... The threaded end passes through the second fixed plate 45 from the outside to the inside and contacts the support rod 41. When the hand-tightened screw 46 contacts the support rod 41, the second fixed plate 45, the first fixed plate 43 and the crossbeam plate 42 can be fixed at a certain height on the support rod 41. Therefore, by adjusting the position of the first fixed plate 43 and the second fixed plate 45 in the slide groove 411, the height of the crossbeam plate 42 can be adjusted so that the watch bar can be more accurately immersed in the water in the cavity of the detection mechanism 2, and the different pressures of the watch bar in the water can be adjusted so as to detect the airtightness of the watch bar under different pressures.

[0029] Please see Figure 5 During testing, the body 6 of the bar needs to be inserted into the sleeve 49 in a horizontal direction, with the two ends of the body 6 of the bar placed on both sides of the sleeve 49.

[0030] Please see Figure 6 The weights 5 can be placed into the weight holes 421 at different positions as needed. In actual use, the number of weights 5 inserted into the weight holes 421 is determined according to the actual needs to increase the weight of the crossbeam plate 42, so that the crossbeam plate 42 can better drive the watch bar to rub against the inner wall of the cavity of the detection pool 21, and avoid the crossbeam plate 42 from shaking too much when moving, which would affect the detection work.

[0031] Working principle: Please refer to the following again. Figures 1 to 5 In this invention, after the bar body 6 is installed on the sleeve 49 and immersed in the detection pool 21, the end of the bar body 6 to be tested is positioned facing the inner wall of the cavity of the detection pool 21. The position of the detection pool 21 is adjusted by rotating the screw 22 so that the end of the bar body 6 to be tested can just contact the inner wall of the cavity of the detection pool 21. Then, the drive cylinder 31 is driven to move the slider 33, which in turn moves the entire support mechanism 4 and the bar body 6 on the support mechanism 4, causing friction between the bar body 6 and the cavity of the detection pool 21. During friction, if the bar body 6 has an airtightness problem, obvious bubbles will be observed in the cavity of the detection pool 21. The airtightness of the bar body 6 can be quickly tested through the above operation. The operation is convenient, the steps are simple, and the testing process is time-saving and labor-saving, enabling large-scale airtightness testing of watch bars.
