Description
Technical Field
The utility model relates to a field of universal joint, concretely relates to a device for maintaining type universal joint leakproofness detects.
Background
When the universal joint normally works, lubricating grease in the bearing plays a lubricating role, and the service life of a product is guaranteed. In order to prevent grease from leaking in the operation process of the universal joint, the universal joint comprises an oil seal rubber part which plays a sealing role, reasonable oil seal size and structure are required to be set in the design process to improve the sealing performance of the universal joint, and meanwhile in the actual manufacturing process, due to the existence of machining errors, the small change of the size of a sealing part often influences or even destroys the sealing performance, so that the sealing performance detection is also very necessary in the development and production processes of the high-end universal joint.
At present, the research on the sealing performance detection test technology of the universal joint in China is less, and the used detection method is to perform a grease leakage test: after the universal joint is assembled with the upper transmission shaft, the actual working condition is simulated on a special test bed, and whether the grease leaks or not is observed. Although the method is relatively consistent with the actual use working condition, the cost is high, and enterprises producing the universal joints often do not have corresponding transmission shafts, cannot perform self-detection and need to give clients of transmission shaft companies to perform tests.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a device for maintaining type universal joint leakproofness detects.
The purpose of the utility model is accomplished through following technical scheme: the utility model provides a device for maintaining type universal joint leakproofness detects, it is main including the water tank, the universal joint, a placement platform, the air gun, it is used for guaranteeing that universal energy-conserving submergence completely to fill with transparent liquid in the water tank, the universal joint includes the glib talker, the cross, the oil blanket, the kingpin, the axle sleeve, a placement platform is located the water tank, a placement platform is last to be equipped with the clamping jaw that is used for pressing from both sides tight fixed universal joint, be equipped with four around a placement platform and be 90 and arrange and install the motor on the guide rail, all be connected with rotatory clamping jaw on every motor and be used for pressing from both sides tight axle sleeve, the air gun is arranged in slowly pouring into the air into to the glib, the air gun is gone up.
Preferably, the transparent liquid is a liquid which has no influence on the surface quality of the universal joint, such as transparent kerosene, antirust liquid and the like.
Preferably, the guide rails of the rotary clamping jaw and the motor have enough stroke, so that the universal joint inspection device can adapt to universal joints with different specifications for inspection.
Preferably, the air flow rate of the air gun injected into the universal joint is as small as possible, so that the air pressure in the universal joint changes slowly, and the reading of the air pressure meter changes slowly, so that the universal joint is convenient to observe.
Preferably, the depth of the placing platform and the clamping jaw from the liquid level is not too large, the depth of the universal joint which is immersed into the liquid level is shallow, and the liquid has small pressure on the oil seal and small interference on the measuring result.
The utility model has the advantages that: the universal joint sealing device has the advantages of being convenient to operate and low in cost, and meanwhile, related detection equipment is designed, so that designers can be helped to know the sealing performance of a universal joint product designed by the universal joint sealing device and the influence of the manufacturing process on the sealing performance.
