Description

Technical Field

[0001] The utility model relates to the technical field of motor housing testing, and more specifically, the utility model relates to a sealing performance testing device for a speed reduction motor housing. Background Art

[0002] A speed reduction motor refers to an integrated body of a speed reducer and a motor (motor), and this integrated body is usually also called a gear motor or a gear motor. The advantages of using a speed reduction motor are simplified design, space saving, and it is commonly used as a speed reduction transmission device between a prime mover and a working machine. It plays a role in matching the rotational speed and transmitting torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery.

[0003] The prior art publication number (CN214426911U) discloses a sealing performance testing device for a speed reduction motor housing. When in use, a slider can be driven by a rodless cylinder to move to the safety door. During the movement, the safety door is pushed open through a transmission rod rotating on a first connecting piece and a second connecting piece, which is convenient for the user to place. The user places the housing body in a positioning groove for clamping. After the clamping is completed, the first pneumatic push rod is opened to reinforce the housing body to prevent it from moving. The slider resets to drive the safety door to close and the detector is opened to control the inflation detection mechanism, the pneumatic plugging mechanism, and the second pneumatic push rod to perform the detection work.

[0004] When the above device is in use, the slider is driven by a rodless cylinder to move to the safety door. During the movement, the safety door is pushed open through the transmission rod, which is convenient for the user to place. After the placement is completed, the slider resets and the safety door closes, which can prevent the user's hand from reaching under the second pneumatic push rod and causing an accident. At the same time, it is convenient for the user to place the housing body in the positioning groove for clamping. After the clamping is completed, the first pneumatic push rod is opened to reinforce the housing body to prevent it from moving. It is convenient to fix and position the installation of the housing body, which speeds up the detection time. However, its internal structure is relatively complex, and at the same time, when detecting the speed reduction motor housing with different installation apertures, it is impossible to effectively ensure the sealing performance of the installation of the speed reduction motor housing main body, and the applicability is poor.
