Description

Technical Field

[0001] The utility model belongs to the field of automatic equipment and relates to a detection machine, in particular to an axial play clearance detection machine for a worm gear assembly. Background Art

[0002] Worm gear reducers are mainly used in motion control applications to reduce speed and increase torque for motors. The axial play clearance of worm gear reducers is also a key control parameter. Too large or too small a clearance will affect the normal operation of the bearing and reducer. In the existing detection method, the axial clearance of worm gear reducers is mainly detected by manually operated dial indicators. This method is cumbersome, takes a long time to clamp, is not very versatile, and human factors lead to large measurement errors, making it difficult to ensure the axial clearance requirements of the reducer.

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 As shown, the worm gear assembly axial play clearance detection machine includes a control system and a frame 1, the frame 1 has a detection station 2, the detection station 2 is provided with a fixture for installing the worm gear assembly, the frame 1 is provided with a detection mechanism 5 for axial play clearance detection, a lifting mechanism 3 for lifting and positioning the fixture is provided below the detection station 2, and a lifting mechanism 4 for resetting the worm gear assembly bearing is also provided below the detection, and the lifting mechanism 4 is located in the center of the lifting mechanism 3. The detection mechanism 5 includes a displacement sensor for axial play clearance detection, a moving device that can drive the displacement sensor to move, and a clamping slide 6 device for clamping a workpiece. The clamping slide 6 device is arranged in a corresponding structure to the lifting mechanism 3, and cooperates with each other to clamp the worm gear assembly. The clamping slide 6 device and the displacement sensor are synchronously moved through the moving device. The frame 1 is also provided with a human-machine display screen 8 that is electrically connected to the control system and is used for data monitoring, display and operation.

[0019] The above structure is reasonably designed, simple and convenient to operate, and the test is accurate and fast. It can overcome the shortcomings of traditional manual detection, such as large test errors, low versatility, cumbersome and time-consuming clamping, and inability to perform online batch detection. It greatly improves the detection efficiency and detection accuracy and reduces labor costs. This detection machine only needs to replace the tooling pressure head and the tooling fixture to be applied to other types of reducers, and even to the detection of axial clearances of motors, gearboxes, etc. It has a wide range of applications and has good application prospects.

[0020] How it works

[0021] 1. The fixture enters the inspection station 2, the pneumatic blocker 7 blocks the limit position, the photoelectric switch confirms the presence of the workpiece (if there is no fixture, the accompanying fixture tray is automatically released), and the lifting mechanism 3 positions and lifts the fixture;

[0022] 2. The pressing slide 6 device and the displacement sensor are lowered to the corresponding position through the moving mechanism. The pressing slide 6 device presses the workpiece. The lifting mechanism 4 first lifts up with a force of 800KG to reset the bearing in the worm gear assembly. The upper displacement sensor moves downward (with a force of 200KG) to make the displacement sensor stick to the plane of the worm gear shaft. The lifting mechanism 4 then lifts up with a force of 400KG to detect the bearing clearance.

[0023] 3. The test result value is displayed on the human-machine display screen 8, and it is automatically determined whether it is qualified (if it is unqualified, the equipment will automatically alarm). After the test is completed, each mechanism returns to its original position.

[0024] To elaborate further, a plurality of pneumatic blockers 7 for blocking and limiting are arranged in the frame 1 , and the pneumatic blockers 7 can be used to block and limit the position of the tooling fixture in the detection station 2 .

[0025] Preferably, the lifting mechanism 3 , the detection mechanism 5 and the lifting mechanism 4 are configured to automatically detect the axial play clearance of the worm gear assembly under the control of the control system, and display the detection data on the human-machine display screen 8 .

[0026] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0027] Although the terms such as frame 1, testing station 2, lifting mechanism 3, lifting mechanism 4, testing mechanism 5, pressing slide 6, pneumatic stopper 7, and human-machine display screen 8 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
