Description

Technical Field

[0001] This utility model relates to the field of grinding wheels, specifically to a grinding wheel that is easy to position and install. Background Technology

[0002] Grinding wheels belong to the field of machining and are widely used in the grinding and processing of workpieces in industries such as machinery manufacturing and mold processing.

[0003] In existing technologies, traditional grinding wheels lack efficient positioning structures during installation, making the process cumbersome and time-consuming, significantly reducing processing efficiency. Their simple positioning structures make it difficult to ensure coaxiality between the grinding wheel and the equipment spindle, easily leading to large vibration amplitudes and poor grinding accuracy, thus affecting the stability of workpiece processing quality. Furthermore, the grinding wheel connection structure has poor adaptability; different equipment often requires different types of grinding wheels, necessitating companies to maintain a stock of various grinding wheel models, increasing their cost burden. Utility Model Content

[0004] The purpose of this utility model is to solve the above defects and provide a grinding wheel that is easy to position and install. It has advantages in achieving rapid positioning and installation, ensuring coaxiality and grinding accuracy, and enhancing equipment adaptability. It solves the technical problems of existing technologies, such as cumbersome and time-consuming installation and positioning, poor grinding accuracy due to insufficient coaxiality, and high cost due to poor equipment adaptability.

[0005] The objective of this utility model is achieved through the following means:

[0006] A grinding wheel for easy positioning and installation includes a base, a positioning component, and a connecting component. The base has a positioning hole at its center, and an annular positioning groove is formed on the inner wall of the positioning hole. The positioning component includes an elastic positioning ring adapted to the annular positioning groove, and a plurality of balls are provided on the elastic positioning ring, with the balls protruding from the annular surface of the elastic positioning ring. The connecting component includes a connecting shaft, one end of which has a flange adapted to the main shaft of the equipment, and the other end of which passes through the positioning hole. The outer wall of the connecting shaft has a limiting platform corresponding to the elastic positioning ring, and the end of the connecting shaft passing through the positioning hole has an end cap. The outer surface of the end cap has an anti-slip rib along its circumference, and the anti-slip rib is fixedly connected to the end cap.

[0007] Through the coordinated operation of the above structures, rapid preliminary positioning and precise installation of the grinding wheel can be achieved, greatly improving installation efficiency. At the same time, it effectively ensures the coaxiality of the grinding wheel and the equipment spindle, thereby improving the stability of grinding accuracy and workpiece processing quality, enhancing adaptability to different equipment to reduce enterprise costs, and preventing the grinding wheel from loosening during use, improving safety and extending the service life of the equipment.

[0008] Furthermore, a screw is provided at one end of the end cap near the connecting shaft, and the screw is fixedly connected to the end cap. The screw is connected to the connecting shaft by a threaded connection.

[0009] Furthermore, the anti-slip ridges improve the anti-slip properties when the hand grips the rotating end cap. The cross-section of the anti-slip ridges is serrated or arc-shaped protrusions, and the distance between two adjacent anti-slip ridges is 1-3mm. The anti-slip ridges are evenly distributed along the outer circumference of the end cap. The addition of anti-slip ridges avoids the problem of uneven slipping force and improves the stability of friction when gripping or engaging tools.

[0010] Furthermore, a hexagonal prism is provided at the center of the end cap opposite to the connecting shaft, and the hexagonal prism is fixedly connected to the end cap. The hexagonal prism facilitates the use of a sleeve tool to control the rotation of the end cap.

[0011] Furthermore, an anti-slip washer is provided on the side of the end cap near the substrate, and the two sides of the anti-slip washer are respectively attached to the end cap and the substrate, thereby improving the anti-slip properties between the substrate and the end cap.

[0012] Furthermore, the limiting platform is fixedly connected to the connecting shaft, the ball bearing is rotatably connected to the elastic positioning ring, and the positioning hole is integrally formed with the base.

[0013] The beneficial effects of this utility model are:

[0014] This utility model achieves rapid initial positioning of the grinding wheel through the cooperation of an elastic positioning ring, annular positioning groove, and ball bearings. This significantly reduces debugging time and improves installation efficiency, solving the problems of cumbersome and time-consuming installation and positioning of traditional grinding wheels. The multi-positioning structure achieves high coaxiality between the grinding wheel and the spindle, reducing vibration amplitude, improving grinding accuracy, and ensuring the stability of workpiece processing quality. This solves the problem of poor grinding accuracy and unstable workpiece quality caused by insufficient coaxiality. The flange connecting the shaft allows for compatibility with different equipment, achieving wide compatibility of the grinding wheel and reducing the need for grinding wheel model inventory, thus lowering enterprise costs.

[0022] like Figure 1 and Figure 4 As shown, the end of the connecting shaft 3 that passes through the positioning hole 2 is provided with an end cap 6. The end of the end cap 6 near the connecting shaft 3 is provided with a screw 13, and the screw 13 is fixedly connected to the end cap 6. The screw 13 is connected to the connecting shaft 3 by a threaded connection.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer side of the end cap 6 is provided with anti-slip ridges 7 along the circumferential direction, and the anti-slip ridges 7 are fixedly connected to the end cap 6. The anti-slip ridges 7 improve the anti-slip performance when the hand rotates the end cap 6 and improve the anti-slip performance when the hand holds and rotates the end cap. The cross-section of the anti-slip ridges 7 is serrated or arc-shaped protrusions, and the distance between two adjacent anti-slip ridges 7 is 1-3mm. The anti-slip ridges 7 are evenly distributed along the outer circumference of the end cap to avoid uneven slipping force and improve the frictional stability when holding or engaging tools.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a hexagonal prism 8 is provided at the center of the end cap 6 away from the connecting shaft 3, and the hexagonal prism 8 is fixedly connected to the end cap 6. The hexagonal prism 8 facilitates the rotation of the end cap 6 using a socket tool.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, an anti-slip washer 9 is provided on the side of the end cap 6 near the base 1, and the two sides of the anti-slip washer 9 are respectively attached to the end cap 6 and the base 1. The anti-slip washer 9 improves the anti-slip performance between the end cap 6 and the base 1.

At this time, the elastic positioning ring 10 in the positioning assembly, which is adapted to the annular positioning groove 12, is engaged in the annular positioning groove 12 on the inner wall of the positioning hole 2. Several balls 11 on the elastic positioning ring 10 protrude from the annular surface and fit against the inner wall of the annular positioning groove 12, completing the initial positioning. Subsequently, the screw 13 of the end cover 6 is aligned with the thread of the end of the connecting shaft 3 and screwed in. Using a socket tool, place it over the hexagonal prism 8 at the end of the end cap 6 facing away from the connecting shaft 3 and rotate it to tighten the end cap 6. During this process, the anti-slip washer 9 on the side of the end cap 6 closest to the base 1 fits against the base 1, and the limiting platform 5 on the outer wall of the connecting shaft 3 abuts against the elastic positioning ring 10 to achieve precise positioning. When the equipment is running, the cooperation of the elastic positioning ring 10 and the ball bearing 11 ensures the coaxiality of the base 1 and the spindle. The anti-slip ridge 7 improves the anti-slip performance when the hand rotates the end cap 6 for assembly and disassembly, the anti-slip washer 9 enhances the anti-slip performance between the end cap 6 and the base 1, and the limiting platform 5 and the elastic positioning ring 10 work together to prevent loosening, ultimately achieving efficient positioning and installation of the grinding wheel and stable grinding operation.
