AI Technical Summary
In existing grinding wheel rotary testing equipment, the positioning shaft is prone to loosening during the testing process, especially the splicing stability at the top and bottom ends is poor, which affects the testing stability.
It adopts a plug-in connector and a pressing mechanism. The combination of the positioning strip of the plug-in connector, the bearing tray, and the pressure plate clamps the grinding wheel synchronously by driving the rotating shaft with a motor. The threaded rod and the pressure cover clamping mechanism ensure stable clamping.
This achieves stable and synchronous rotation of the grinding wheel, improving the stability and convenience of testing and avoiding the potential risks of frequent adjustments to the positioning axis.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grinding wheel testing technology, specifically relating to a grinding wheel rotation testing mechanism. Background Technology
[0002] Grinding wheels are commonly used grinding tools, widely applied in the surface treatment of metals and other materials in the machining industry. Grinding wheels are made by mixing abrasive particles with a binder, pressing them into shape, and then sintering or curing them at high temperatures. Their quality directly affects grinding efficiency, machining accuracy, and safety. Therefore, after the grinding wheel is produced, testing its rotational strength based on differences in diameter, mass, and maximum operating speed is an essential step in the quality inspection of grinding wheels.
[0003] Patent CN221302957U discloses a vertical rotary strength testing machine for grinding wheels. It uses a docking seat and a docking block for splicing, and then locks the docking seat and the docking block by the elastic compression of a spring via a positioning shaft. Multiple grinding wheels can be tested simultaneously. However, in this solution, the splicing of the docking seat and the docking block is first limited by the positioning shaft to the hole, and then locked by the spring. The main force relies on the spring's compression. During the rotary testing process, the spring is compressed due to centrifugal force, causing the positioning shaft to loosen, posing a potential hazard; especially the splicing stability at the top and bottom is poor. Utility Model Content
[0004] In view of the problems mentioned in the background art above, this utility model provides a grinding wheel rotation detection mechanism.
[0005] The technical solution adopted by this utility model is as follows: A grinding wheel rotation detection mechanism includes a base and connectors. A rotating shaft is provided on the base, and the rotating shaft is driven by a motor. The connectors include a plug-in post and a connecting post. A positioning strip is integrally formed on the outer circumference of the plug-in post. A connecting cavity matching the plug-in post is opened at the top of the connecting post. A support plate is provided in the middle of the outer circumference of the connecting post. The plug-in post is located at the bottom end of the connecting post. A pressure plate is provided at the connection between the plug-in post and the connecting post. A mounting seat is provided on the rotating shaft. A mounting cavity matching the plug-in post is provided on the mounting seat. Several connectors are sequentially inserted along the axis of the mounting seat. A pressing mechanism is provided on the base for pressing down and tightening several connectors.
[0006] Furthermore, the pressing mechanism includes a pressure cap and a mounting bracket mounted on the base. A threaded rod is threadedly connected to the mounting bracket, and a plug-in block matching the connecting post is provided at the bottom of the pressure cap. The pressure cap is pressed tightly by the threaded rod.
[0007] Furthermore, the top of the pressure cap is provided with a center hole, and the bottom of the threaded rod is rotatably provided with a center corresponding to the center hole.
[0008] Furthermore, a handwheel is provided on the top of the threaded rod passing through the mounting bracket.
[0009] Furthermore, the pressure plate is made of rubber.
[0010] The beneficial effects of this utility model are:
[0011] The grinding wheel is clamped by two connectors, with the wheel fitted around the outer circumference of the connecting column. The bottom of the wheel is supported by a support tray, and the top is pressed by a pressure plate. Because positioning strips are provided on the outer circumference of the connectors, after several connectors are mated together, the rotating shaft can rotate synchronously via a motor. Multiple grinding wheels are then firmly clamped between the support tray and the pressure plate by the overall pressing mechanism, achieving synchronous rotation and completing the rotation test. The overall structure is simple and easy to install; it eliminates the need for frequent adjustments to the positioning shaft and offers high stability. Attached Figure Description

Detailed Implementation
[0018] like Figures 1-3As shown, a grinding wheel rotation detection mechanism includes a base 1 and a connector 3. A rotating shaft 2 is provided on the base 1, and the rotating shaft 2 is driven by a motor. The connector 3 includes a connector post 31 and a connecting post 32. The outer circumference of the connector post 31 is integrally formed with a positioning strip 311. The top of the connecting post 32 has a connecting cavity 321 that matches the connector post 31. A support plate 33 is provided in the middle of the outer circumference of the connecting post 32. The connector post 31 is located at the bottom of the connecting post 32. A pressure plate 34 is provided at the connection between the connector post 31 and the connecting post 32. A mounting seat 21 is provided on the rotating shaft 2. The mounting seat 21 has a mounting cavity 22 that matches the connector post 31. Several connectors 3 are sequentially inserted along the axis of the mounting seat 21. A pressing mechanism is provided on the base 1 for pressing down and tightening several connectors 3.
[0019] By adopting the above technical solution, such as Figure 3 As shown, the grinding wheel 6 is clamped by two connectors 3. The grinding wheel 6 is sleeved on the outer periphery of the connecting column 32. The bottom of the grinding wheel 6 is supported by the support tray 33, and the top is pressed by the pressure plate 34. Since the outer periphery of the connector 31 is provided with positioning strips 311, after several connectors 3 are connected, the rotating shaft 2 driven by the motor installed on the base 1 (not shown in the figure) can rotate synchronously. After multiple grinding wheels 6 are pressed together by the pressing mechanism, they are stably clamped between the support tray 33 and the pressure plate 34, achieving synchronous rotation and completing the rotation test. The overall structure is simple and easy to install; it does not require frequent adjustment of the positioning shaft and has high stability.

The pressure cover 4 is pressed tightly by the threaded rod 5. The top of the pressure cover 4 is provided with a center hole 42. The bottom of the threaded rod 5 is rotatably provided with a center 51 corresponding to the center hole 42. Through the threaded connection between the threaded rod 5 and the mounting bracket 11, the center 51 is driven to move downward and extend into the center hole 42 of the pressure cover 4. At this time, the plug-in block 41 of the pressure plate 34 matches the connecting post 32, and the whole is pressed tightly, realizing the function of fixing the axis.
[0021] As a preferred embodiment, the threaded rod 5 is provided with a handwheel 52 passing through the top of the mounting bracket 11. The handwheel 52 is designed for easy rotation.
