Description

Technical Field

[0001] This utility model relates to the field of testing fixtures for rotary speed reducers, and in particular to a testing fixture for rotary speed reducers. Background Technology

[0002] Speed ​​reducers play a role in matching speed and transmitting torque between prime movers and working machines or actuators. They are widely used in modern machinery. Speed ​​reducers can be divided into two main categories according to their uses: general-purpose speed reducers and special-purpose speed reducers. The design, manufacturing and usage characteristics of the two are different.

[0003] The existing method achieves a hard connection between the motor and the reducer by adjusting the height of the motor. This is troublesome to adjust each time a different type of reducer is changed, the coaxial precision requirement is too high, and it is impossible to quickly match and test the connection.

[0004] This utility model, as disclosed in the patent (publication number: CN221781852U), relates to the field of speed reducers and specifically discloses a speed reducer testing fixture, including a support base plate. A first base and a second base are symmetrically fixed to the upper surface of the support base plate. Initial installation is completed by placing the speed reducer body in the mounting groove for fixation. Then, a belt is prepared and connected to the shaft to be tested on the speed reducer. The up-and-down adjustment unit is then controlled to move upwards until the distance is less than the belt, facilitating the installation of the belt onto the pulley. After the belt is installed, the up-and-down adjustment unit is controlled to pull downwards to tighten the belt and fix it in place. Then, the test motor is started for testing. After the test is completed, the up-and-down adjustment unit is controlled to move upwards until the distance is less than the belt, facilitating the removal of the belt from the pulley. This achieves the function of quickly and safely changing different speed reducers and installing belts, solving the problem of cumbersome and inefficient connection between the motor and speed reducer in existing testing fixtures.

[0005] To address the aforementioned issues, existing patents offer solutions. Most of these solutions focus on testing the mechanical functions of the speed reducer. However, due to the wide range of applications for speed reducers, a sealing test is required during the manufacturing process. Existing sealing test structures use a gantry frame with chains to adjust the height of the speed reducer. Because the speed reducer itself is quite heavy, adjusting its height via chains can easily cause positional deviations in the speed reducer during testing, thus affecting the accuracy of the sealing test.

[0006] Therefore, a test fixture for rotary reducers is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a testing fixture for rotary speed reducers, which can solve the problem that most existing fixtures test the mechanical functions of speed reducers. Since speed reducers have a wide range of applications, they need to be tested for sealing during the manufacturing process. Existing sealing test structures use a gantry frame and iron chains to adjust the height of the speed reducer. Because the speed reducer itself is heavy, adjusting the height of the speed reducer by iron chains or other means can easily cause positional deviation of the speed reducer body during the test, which affects the accuracy of its sealing test.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a rotary reducer testing fixture, including a support base, an adjustment groove being provided on the top of the support base, an adjustment component being provided on the top of the support base, and a water storage component being fixedly connected to the top of the support base;

[0009] The adjustment assembly includes a first servo motor body. A threaded rod is fixedly connected to the rear side of the first servo motor body. An adjustment block that mates with an adjustment groove is threadedly connected to the surface of the threaded rod. A support frame is fixedly connected to the top of the adjustment block. An electric telescopic rod body is fixedly connected to the top of the support frame. A fixing block is fixedly connected to the bottom of the electric telescopic rod body. A sliding groove is formed on the rear side of the fixing block. A second servo motor body is fixedly connected to the right side of the inner wall of the sliding groove. A bidirectional helical rod is fixedly connected to the left side of the second servo motor body. Two sliding blocks that mate with the sliding groove are threadedly connected to the surface of the bidirectional helical rod. A support plate is fixedly connected to the rear side of each sliding block. An anti-slip pad is fixedly connected to the top of each support plate. An air pump body is fixedly connected to the right side of the support frame. A connecting pipe is connected to the top of the air pump body. A connecting tube is snapped onto the side of the connecting pipe away from the air pump body.

[0010] Preferably, a water tank is fixedly connected to the top of the support base, a groove is provided on the rear side of the inner wall of the water tank, a heating rod is fixedly connected inside the groove, and an electronic valve body is connected to the left side of the water tank.

[0011] Preferably, a baffle is snapped into the inside of the water tank, a filter screen is fixedly connected inside the baffle, and a temperature detector body is fixedly connected to the right side of the water tank.

[0012] Preferably, a pull-out block is fixedly connected to the top of the shielding frame, the pull-out block is made of stainless steel, and a transparent glass is fixedly connected to the right side of the water tank.

[0013] Preferably, the top of the support base is provided with a sliding groove, the bottom of the support frame is fixedly connected to a slider, and the inner wall of the sliding groove is fixedly connected to a circular rod, which is slidably connected inside the slider.

[0014] Preferably, the top of the support base is provided with a placement groove, and an absorbent pad is engaged inside the placement groove.

[0015] Preferably, a housing is fixedly connected to the bottom of the support base, and a storage box is slidably connected inside the housing.

[0016] Preferably, the storage box has a protective pad inside, and the top of the protective pad has several placement slots. The protective pad is made of sponge.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting an adjustment component, can achieve the effect of adjusting the position of the reducer body. According to the shape of the reducer and the testing requirements, the user first uses the second servo motor body, bidirectional screw rod and sliding block to precisely adjust the position of the two support plates to adapt to the bottom shape of the reducer. Then, the height of the fixed block is adjusted by the electric telescopic rod body to further adjust the height of the reducer. Finally, the adjustment block is operated by the first servo motor body and screw rod to precisely adjust the position of the support frame, that is, the overall position of the reducer, to ensure that the reducer is in the right position during the test and improve the accuracy of the test. Since the position and height of the two support plates can be flexibly adjusted, this adjustment component can adapt to reducers of different shapes and sizes. Whether it is a large or small, regular or irregular shape reducer, it can be accurately positioned and placed by the adjustment component, which enhances the versatility of the test fixture.

[0019] 2. This application, by setting up a water storage component, can achieve the effect of testing the sealing performance of the reducer in conjunction with the adjustment component. During the testing process, the reducer can be partially or completely immersed in the water in the tank. Then, by introducing gas into the reducer, the sealing performance of the reducer can be judged by observing whether air bubbles are generated in the water. If air bubbles are generated, it indicates that there is a leak in the reducer. This testing method is intuitive and effective. A heating rod is installed in the groove on the rear side of the inner wall of the water tank. The user can operate the heating rod as needed to heat the water in the tank. The temperature detector can monitor the water temperature in real time to control the water temperature within a suitable range. A suitable water temperature may be necessary for some special test scenarios, such as simulating the working state of the reducer under different temperature environments, thereby more comprehensively testing the performance of the reducer.
