Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing seat processing, in particular to a polishing machine for bearing seat processing. Background Art
[0002] The bearing seat is a component used to install and support bearings in mechanical equipment. It enables the bearings to be correctly positioned and withstand axial and radial loads.
[0003] Bearing seats are usually made of cast iron, steel or other alloy materials, and have certain strength and rigidity to ensure the normal operation of mechanical equipment and the service life of bearings. After the bearing seat is produced, the surface of the bearing seat needs to be polished. The polishing of the bearing seat is mainly to improve its appearance quality, reduce surface roughness, remove burrs and oxide layers, and sometimes to prepare for subsequent painting or special surface treatment. Generally, after the bearing seat is cleaned with water and blown dry, a polishing machine is used to polish the surface of the bearing seat.
[0004] However, when polishing some bearing seats with higher precision, the area where the inner diameter of the bearing seat contacts the bearing surface also needs to be polished. In order to ensure a smooth and delicate surface, polishing paste needs to be applied to the inner diameter of the bearing seat before polishing. Generally, the operator manually squeezes the polishing paste and evenly applies the polishing paste to the inner diameter of the bearing seat. However, the polishing paste is manually extruded, and it is easy for too much or too little polishing paste to be squeezed out. If too much polishing paste is squeezed out, the polishing paste will be wasted. If too little polishing paste is squeezed out, the polishing of the inner diameter may not achieve the expected goal. In addition, in order to reduce the workload, the operator may directly squeeze the polishing paste onto the inner wall of the bearing seat without applying it. This may cause surface damage to the inner diameter of the bearing seat. At the same time, due to the lack of polishing paste, the heat cannot be effectively dissipated, and the bearing seat will suffer thermal damage. In view of this, a polishing machine for bearing seat processing is provided to overcome the above-mentioned defects. Utility Model Content

[0028] As above, the dual-axis motor 4 used in the present application is a 50mm standard dual-axis motor of PK258-02B that has been mass-produced on the market.
[0029] Working principle:
[0030] When using the utility model, the polishing paste is injected into the storage tank 6 from the top. After the injection is completed, the right output end of the dual-axis motor 4 is opened. The right output end of the 50mm standard dual-axis motor 4 of PK258-02B is connected to the vacuum pump 5. The vacuum pump 5 is started, the polishing paste in the storage tank 6 is extracted, and injected into the hollow ring 19 through the connecting hose 7. The hole opened on the inner wall of the hollow ring 19 is flush with the hole opened inside the hollow tube 11. The polishing paste enters the hollow tube 11 through the two holes, and then enters the inside of the rotating drum 8 through the hollow tube 11. After filling, the outer side of the bearing seat can be polished. The polishing machine body 2 at the top and rear of the operating table 1 is opened, and the surface of the bearing seat is attached to the polishing wheel of the polishing machine body 2 for surface polishing. When the inner diameter part of the bearing seat needs to be polished, the operator only needs to push the receiving plate 9 downward. The receiving plate 9 drives the slider 16 to slide downward along the outer side of the limit rod 15 through the connecting rod 18, and the tension spring 17 is deformed. The operator places the bearing seat horizontally on the receiving plate The top of the material plate 9 cooperates with the resilience of the tension spring 17 to sleeve the inner diameter of the bearing seat on the outside of the rotating drum 8. At this time, the output end of the bottom of the dual-axis motor 4 is opened, and the motor shaft 10 at the bottom output end of the dual-axis motor 4 drives the hollow tube 11 and the rotating drum 8 to rotate. At this time, the polishing paste inside the rotating drum 8 moves outward due to the centrifugal force generated by the rotation, and after passing through the metal mesh 13 fixed with the frame 12, it directly contacts the inner diameter part of the bearing seat. At this time, the polishing paste cooperates with the rotating surface of the rotating drum 8 to be evenly applied to the inner diameter part of the bearing seat. After the rotating drum 8 rotates for two weeks, the bottom output end of the dual-axis motor 4 can be closed, and the right output end can be opened to refill the polishing paste inside the rotating drum 8. The polishing paste overflowing from between the rotating drum 8 and the inner diameter of the bearing seat is received by the receiving plate 9. At this time, the operator can press downward to allow the receiving plate 9 to move downward until the bearing seat is taken out from the outside of the rotating drum 8. After the bearing seat is removed from the receiving plate 9, the inner diameter part of the bearing seat can be sleeved on the outer side of the polishing wheel at the output end of the polishing machine body 2 for polishing.
