Description

Technical Field

[0001] The utility model relates to the technical field of grinding machine processing, in particular to a magnetic pole for inner ring grinding machines. Background Art

[0002] The existing internal cylindrical grinder uses bearing steel as the pole material, and there is no coating on the surface after quenching. During the grinding process of the bearing ring, in order to ensure the vertical difference of the grinding product, the pole surface will be constantly worn (static friction and friction during loading and unloading), and needs to be continuously ground flat. 200 pieces need to be ground once, which reduces production efficiency and unstable product quality. Summary of the invention

[0003] In order to solve the above problems, the purpose of the utility model is to provide a magnetic pole for an inner ring grinding machine, adding a wear-resistant coating on the surface of the magnetic pole. The coating has a high hardness and is not easy to wear. After the bearing model is changed, the magnetic pole surface does not need to be frequently polished, which increases the stability of product quality and improves production efficiency.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] A magnetic pole for an inner ring grinding machine, one end of the magnetic pole is axially mounted on the grinding machine workbench, the other end of the magnetic pole is axially inwardly constructed with a groove with a circular cross-section, and a circle of magnetic adsorption end face is formed on the outer side of the groove. It is characterized in that: the magnetic adsorption end face is plated with a circle of wear-resistant coating, and the axial end face of the bearing ring is adsorbed and abutted against the outer end face of the wear-resistant coating.

[0006] In the above technical solution, a wear-resistant coating is added to the surface of the contact between the magnetic pole and the bearing ring. The hardness of the coating is high and it is not easy to wear. After the bearing model is changed, the surface of the magnetic pole does not need to be polished frequently, which increases the stability of product quality and improves production efficiency. According to actual verification, the production efficiency is improved by 10%. The original 200 pieces are polished once, but after using this magnetic pole with wear-resistant coating, it only needs to be polished once per shift. The original production of 1680 pieces per shift has increased to 1780 pieces, and the production efficiency has been improved.

[0007] Preferably, the radial width of the wear-resistant coating is the same as that of the magnetic adsorption end face. In this technical solution, the radial width of the wear-resistant coating is the same as that of the magnetic adsorption end face, that is, the magnetic adsorption end face is fully coated, which is convenient for plating, and at the same time increases the abutment adsorption area, thereby improving the adsorption and fixing effect on the bearing ring.

[0008] Preferably, the wear-resistant coating is a ceramic coating. In this technical solution, the ceramic coating has high wear resistance. It should be noted that the ceramic coating is relatively thin and the magnetism can penetrate the ceramic coating to ensure the adsorption effect on the bearing ring.

[0009] Preferably, the magnetic adsorption end surface is provided with a plurality of notches along the axial direction, and the notches are constructed to connect the groove and the outside of the magnetic pole. In this technical solution, the grinding chips generated by the grinding wheel when grinding the inner wall of the bearing ring can be discharged from the notches in time, reducing interference with the grinding process. At the same time, the corresponding adsorption area of ​​the bearing ring and the magnetic pole is increased, and the adsorption and fixing effect of the bearing ring is improved.

[0010] Preferably, the plurality of notches are regularly arranged radially on the magnetic adsorption end surface. In this technical solution, the plurality of notches are regularly arranged radially, so that the wear debris can be easily discharged from the notches in the circumferential direction, and the adsorption effect of the magnetic adsorption end surface on the bearing ring is roughly the same at all locations.

[0011] Preferably, the inner side wall of the groove is constructed as an inclined wall with an inner diameter gradually increasing from the inside to the outside. In this technical solution, the grinding debris generated by the grinding wheel when grinding the inner wall of the bearing ring can be guided from the inclined wall to the notch after passing through the inner inclined wall of the groove.

[0019] like Figure 1~2 A magnetic pole for an inner ring grinding machine is shown, wherein one end of the magnetic pole 1 is axially mounted on the workbench of the grinding machine, and the other end of the magnetic pole 1 is axially inwardly constructed with a groove 2 with a circular cross-section, and a circle of magnetic adsorption end face 3 is formed on the outer side of the groove 2, which is characterized in that: a circle of wear-resistant coating 4 is plated on the magnetic adsorption end face 3, and the axial end face of the bearing ring 100 is adsorbed and abutted against the outer end face of the wear-resistant coating 4.

[0020] In the above technical solution, a wear-resistant coating is added to the surface of the contact between the magnetic pole and the bearing ring. The hardness of the coating is high and it is not easy to wear. After the bearing model is changed, the surface of the magnetic pole does not need to be polished frequently, which increases the stability of product quality and improves production efficiency. According to actual verification, the production efficiency is improved by 10%. The original 200 pieces are polished once, but after using this magnetic pole with wear-resistant coating, it only needs to be polished once per shift. The original production of 1680 pieces per shift has increased to 1780 pieces, and the production efficiency has been improved.

[0021] Furthermore, the radial width of the wear-resistant coating 4 is the same as that of the magnetic adsorption end face 3. In this technical solution, the radial width of the wear-resistant coating is the same as that of the magnetic adsorption end face, that is, the magnetic adsorption end face is fully coated, which is convenient for plating, and at the same time increases the abutment adsorption area, thereby improving the adsorption and fixing effect on the bearing ring.

[0022] Furthermore, the wear-resistant coating 4 is a ceramic coating. In this technical solution, the ceramic coating has high wear resistance. It should be noted that the ceramic coating is relatively thin, and magnetism can penetrate the ceramic coating to ensure the adsorption effect on the bearing ring.

[0023] Furthermore, the magnetic adsorption end surface 3 is cut with a plurality of notches 5 along the axial direction, and the notches 5 are constructed to connect the groove 2 with the outside of the magnetic pole 1. In this technical solution, the grinding chips generated by the grinding wheel when grinding the inner wall of the bearing ring can be discharged from the notches in time, reducing interference with the grinding process. At the same time, the corresponding adsorption area of ​​the bearing ring and the magnetic pole is increased, and the adsorption and fixing effect of the bearing ring is improved.

[0024] Furthermore, the plurality of notches 5 are regularly arranged radially on the magnetic adsorption end surface 3. In this technical solution, the plurality of notches are regularly arranged radially, so that the wear debris can be easily discharged from the notches in the circumferential direction, and the adsorption effect of the magnetic adsorption end surface on the bearing ring is roughly the same at all locations.

[0025] Furthermore, the inner side wall of the groove 2 is constructed as an inclined wall 6 whose inner diameter gradually increases from the inside to the outside. In this technical solution, the grinding debris generated by the grinding wheel when grinding the inner wall of the bearing ring can be guided from the inclined wall to the notch after passing through the inner inclined wall of the groove.

[0026] In this specific embodiment, in order to solve the problem that the existing magnetic pole surface is easy to wear and needs to be frequently polished, resulting in low production efficiency, the above scheme adds a wear-resistant coating on the surface of the contact between the magnetic pole and the bearing ring. The coating has a high hardness and is not easy to wear. After the bearing is changed, the magnetic pole surface does not need to be frequently polished, which increases the stability of product quality and improves production efficiency. According to actual verification, the production efficiency is improved by 10%. The original 200 pieces are polished once, but after using this magnetic pole with wear-resistant coating, it only needs to be polished once per shift. The original production of 1680 pieces per shift is increased to 1780 pieces, and the production efficiency is improved.
