Description

Technical Field

[0001] The utility model relates to the technical field of vacuum equipment, in particular to a sealing detection device for vacuum equipment production. Background Art

[0002] After searching the patent document with the announcement number CN216524583U, the patent document shows that the product to be tested is placed in the clamping plate, and the product is fixed by adjusting the sliding rod and the slider, and then clean water is added to the machine body, the machine cover is closed, and the push rod is pushed to drive the pressure plate downward to increase the internal pressure. If the sealing effect of the product is poor, water will enter the product through the observation window;

[0003] When this patent is in use, the clamp may cause damage to the product. It is also inconvenient to fix products with special structures. The operator needs to push the push rod while observing, and the test results are prone to errors. If the outer side of the product to be tested is opaque, the sealing cannot be determined. After the test, water droplets remain on the surface of the product, which is not convenient for subsequent storage or use. Utility Model Content

[0014] Preferably, the detection barrel and the water tank are connected via a pipe passing through the workbench.

[0015] The beneficial effects compared with the prior art are as follows:

[0016] 1. The pressure inside the test barrel is increased by the pressurized hydraulic cylinder, which can stably adjust the pressure. At the same time, the water in the water tank can be reused to save water resources;

[0027] The utility model is further described below in conjunction with the accompanying drawings:

[0028] like Figure 1-Figure 4 As shown, a sealing detection device for vacuum equipment production includes a support mechanism 1, a sealing mechanism 3 is arranged on the support mechanism 1, and also includes a fixing mechanism 2 for limiting the position of the product to be detected and a pressurizing mechanism 4 for controlling the pressure of the device;

[0029] In this embodiment: the fixing mechanism 2 includes a motor 21, the output shaft of the motor 21 is connected to the transmission shaft 22 through a coupling, the transmission shaft 22 extends into one end of the supporting mechanism 1 and is fixed with a rotating table 23, and a placement box 24 is welded on the rotating table 23. After the inspection, the motor 21 drives the transmission shaft 22 to rotate, and the rotating table 23 at the upper end of the transmission shaft 22 rotates accordingly, and the placement box 24 also rotates to shake off the water droplets on the surface of the product.

[0030] In this embodiment: the pressurizing mechanism 4 includes a water tank 41, and a water pressure plate 42 is provided on the side of the water tank 41 away from the motor 21. The water pressure plate 42 is fixedly connected to the telescopic part of the pressurizing hydraulic cylinder 43. When the detection starts, the pressurizing hydraulic cylinder 43 is started, and the telescopic part of the pressurizing hydraulic cylinder 43 pushes the water pressure plate 42 to slide in the water tank 41, thereby increasing the pressure inside the device.

[0031] In this embodiment: the support mechanism 1 includes a workbench 11, a bracket 12 is welded above the workbench 11, a detection barrel 13 is arranged in the middle of the bracket 12, the detection barrel 13 and the water tank 41 are connected by a pipeline passing through the workbench 11, a pressure gauge 14 is installed on the detection barrel 13, and a fixing platform 15 for fixing the pressurized hydraulic cylinder 43 is arranged on the lower side of the workbench 11. The bracket 12 is used to fix the sealing hydraulic cylinder 31, the pressure gauge 14 is used to observe the pressure inside the detection barrel 13, and the fixing platform 15 is used to fix the pressurized hydraulic cylinder 43.

[0032] In this embodiment: the sealing mechanism 3 includes a sealing hydraulic cylinder 31, which is connected to the bracket 12 by bolts. The telescopic part of the sealing hydraulic cylinder 31 is fixedly connected to a sealing cover 32. A rubber ring 33 for improving the sealing performance of the device is installed on the outer side of the sealing cover 32. A support frame 34 is welded to the lower side of the sealing cover 32, and a mesh cover 35 is arranged on the lower side of the support frame 34. The inside of the mesh cover 35 is a nylon woven mesh cover. An annular protrusion is arranged on the upper side of the placement box 24, and an annular groove is opened on the lower side of the support frame 34. When the placement box 24 and the support frame 34 are in contact, they are slidably connected. After the product to be tested is placed, the sealing hydraulic cylinder 31 is started, and the telescopic part of the sealing hydraulic cylinder 31 drives the sealing cover 32 to move downward. The annular groove on the lower side of the support frame 34 is plugged into the annular protrusion on the upper side of the placement box 24, so that the position of the product to be tested is limited within the placement box 24 and the mesh cover 35.

[0033] Working principle: When in use, first pour a certain amount of clean water into the water tank 41 and the detection barrel 13, put the product to be detected into the placement box 24, start the sealing hydraulic cylinder 31, and the telescopic part of the sealing hydraulic cylinder 31 drives the sealing cover 32 to move into the detection barrel 13. The rubber ring 33 on the sealing cover 32 fits with the detection barrel 13 to improve the sealing inside the detection barrel 13. The sealing cover 32 continues to move down until the annular groove on the lower side of the support frame 34 is plugged into the annular protrusion on the upper side of the placement box 24, limiting the position of the product to be detected in the placement box 24 and the mesh cover 35. At this time, the pressurized hydraulic cylinder 43 is started, and the telescopic part of the pressurized hydraulic cylinder 43 pushes the water pressure plate 42 to move toward the detection barrel 13, and the water pressure plate 42 slides in the water tank 41. The water in the water tank 41 is pushed into the detection barrel 13 to cover the product to be detected, and the pressure inside the detection barrel 13 is increased. By observing the pressure gauge 14, the pressurizing hydraulic cylinder 43 is stopped when the pressure is sufficient; after maintaining for a period of time, the pressurizing hydraulic cylinder 43 is started to withdraw the water pressure plate 42, and the clean water falls back into the water tank 41, and the motor 21 is started again. The motor 21 controls the transmission shaft 22 to rotate, thereby driving the rotating table 23 at the upper end of the transmission shaft 22 to rotate, and the placement box 24 also rotates. The annular protrusion on the upper side of the placement box 24 slides in the annular groove on the lower side of the support frame 34. Under the condition of ensuring that the product is not thrown out, the water droplets on the surface of the product inside the placement box 24 are thrown off, so as to facilitate the subsequent judgment of whether the sealing is qualified.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
