Description

TECHNICAL FIELD

[0001] The utility model relates to foundry technology field especially relates to a combination grinding abrasive. BACKGROUND

[0002] The cost of enterprises in production activities gradually increases, and the profit space is reduced, so the enterprise must continuously optimize the production process, improve the production efficiency and reduce the cost.

[0003] The abrasive used in the traditional casting grinding of the riser and the burr is extremely complicated in the type and the material, and this complexity brings many inconveniences in the grinding operation process, because the characteristics of different parts of the casting are different, and different types and materials of abrasives need to be used for processing, which means that the operator needs to frequently change different abrasives during the operation process, however, this abrasive changing operation has many disadvantages, each time the abrasive is changed, the operator needs to stop the grinding work being carried out, find the appropriate abrasive, and then install the new abrasive on the grinding equipment, this process involves many steps such as equipment adjustment and abrasive positioning, and the operation is relatively complicated, so that the abrasive changing time is relatively long, and moreover, this frequent interruption and restart of the grinding operation seriously affects the smoothness of the whole operation process. SUMMARY

[0004] In order to solve the above technical problems, the utility model provides a combination grinding abrasive.

[0005] The utility model adopts the following technical scheme: a combination grinding abrasive, including first abrasive head, the bottom of first abrasive head is connected with second abrasive head in screw thread, the surface of second abrasive head is provided with stop washer, the inner wall of stop washer is fixedly connected with sealing washer.

[0006] By the technical scheme, the combined grinding abrasive is formed by the threaded connection of the first abrasive head and the second abrasive head, cooperates with the stop washer and the sealing washer, and realizes grinding of different positions through programming, thereby greatly reducing the abrasive replacement time. In mass production, frequent replacement of abrasives is a time-consuming process, and the combined abrasive can automatically switch the appropriate abrasive according to different positions of the casting, so that the operation process is smoother, the production interruption caused by replacement of abrasives is avoided, the production efficiency is significantly improved, and in the grinding process, the vibration of the equipment or the reaction force generated during grinding may have a tendency to loosen the threaded connection, the stop washer can effectively prevent such loosening, which increases the friction force through the contact with the surface of the second abrasive head and the structural characteristics of the stop washer, prevents the rotation of the first abrasive head relative to the second abrasive head, and thus ensures the stability of the entire grinding abrasive structure, ensures that the grinding work can be continuously and stably carried out, and the sealing washer is fixed to the inner wall of the stop washer, which can effectively seal the connection part of the first abrasive head and the second abrasive head and prevent abrasive particles from entering from the connection part.

[0007] As a further improvement of the above scheme, the shape of the first abrasive head is a column.

[0008] Through the above technical scheme, the column shape makes the abrasive head have good stability when processing parts with large grinding amount, which can provide a larger contact area and uniformly distribute the grinding pressure when grinding the surface of the casting with a large area, thereby avoiding the uneven grinding phenomenon caused by excessive local pressure.

[0009] As a further improvement of the above scheme, the shape of the second abrasive head is a cone.

[0010] Through the above technical scheme, the sharp end of the cone can penetrate into narrow spaces for precise grinding, and can effectively grind small parts or corners of complex-shaped castings. When processing small grinding amount parts, the conical abrasive head can better control the range and depth of grinding, reduce the influence on the surrounding areas that do not need to be ground, thereby improving the grinding accuracy and making the overall grinding effect of the casting more perfect.

[0011] As a further improvement of the above scheme, the inner wall of the first abrasive head is provided with internal threads.

[0012] Through the above technical scheme, the existence of internal threads makes the connection between the abrasive heads tight and stable. This connection mode not only ensures that the first abrasive head and the second abrasive head will not accidentally separate during grinding, ensuring the continuity of the grinding work, but also facilitates the disassembly operation when adjusting or replacing the abrasive head, making the maintenance work more convenient and reducing the equipment downtime.

[0013] As a further improvement of the above-mentioned scheme, the outer surface of the second abrasive head is provided with external threads.

[0014] As a further improvement of the above-mentioned scheme, the external threads are adapted to the internal threads.

[0015] As a further improvement of the above-mentioned scheme, the upper surface of the first abrasive head is fixedly connected with a mounting screw.

[0016] By the above technical scheme, the mounting screw can accurately position and fix the combined abrasive on the grinding equipment, and the high-speed operation or large grinding force of the grinding equipment may cause displacement of the abrasive during grinding, but the mounting screw can effectively prevent this situation, which ensures that the grinding operation is always carried out at the predetermined position and direction, improves the accuracy of grinding, and also helps to prolong the service life of the grinding equipment and the abrasive.

[0017] Compared with the prior art, the utility model has the advantages that:

[0018] The combined abrasive composed of the first abrasive head and the second abrasive head greatly reduces the abrasive replacement time, avoids production interruption caused by frequent replacement of abrasives in large-scale production, makes the operation process more smooth, significantly improves the production efficiency, the stop washer is in surface contact with the second abrasive head and increases the friction force by using its structural characteristics, prevents the first abrasive head from rotating relative to the second abrasive head, guarantees the stability of the grinding abrasive structure, prevents the threaded connection from loosening due to equipment vibration or grinding reaction force, and the sealing gasket is fixed on the inner wall of the stop washer, can effectively seal the connection part of the first abrasive head and the second abrasive head, and prevents abrasive particles from entering from the connection.
