Description

Technical Field

[0001] The utility model relates to the field of bearing ball production, in particular to a polishing device for bearing ball production. Background Art

[0002] The bearing is a component that fixes and reduces the load friction coefficient during mechanical transmission. The ball is placed between the inner circle and the outer circle. In order to make the surface of the ball smoother, the ball is polished by a vibration polisher or a drum polisher. A Chinese utility model patent with the announcement number CN 213795925U discloses a ball polishing device for bearing processing, which mainly includes a vibration limiter component, a base and a storage bin. Through the mutual cooperation between the vibration limiter component, the base and the storage bin, the polishing of the bearing ball can be made more efficient and convenient, and the separation of the ball and the polishing agent can be made more convenient, thereby effectively improving the polishing efficiency of the ball.

[0003] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the above-mentioned device is a vibration polishing machine, which usually fills a certain amount of polishing sand in the polishing chamber, and then places the workpiece inside for polishing. After polishing the ball, the ball needs to be separated from the polishing sand. In the above structure, the ball can be taken out after polishing, but there is no corresponding structure for taking out the polishing sand, which requires a separate tool to take out the polishing sand during the next polishing. For this reason, we designed a polishing device for bearing ball production. Utility Model Content

[0004] In order to solve the technical problem that it is difficult to remove the internal polishing sand, the utility model provides a polishing device for bearing ball production.

[0005] The utility model is implemented by the following technical scheme: a polishing device for bearing ball production, including a polishing chamber, six spring seats distributed in an annular shape are arranged on the bottom surface of the polishing chamber, the bottom ends of the spring seats are installed on a base, and three vibration motors arranged in a circumferential array are installed on the bottom surface of the polishing chamber, a discharge pipe is welded at the middle of the bottom end of the polishing chamber, and the discharge pipe is connected to the inside of the polishing chamber, the lower end of the discharge pipe is connected to a guide pipe, the other end of the guide pipe is placed outside the base, and a separation component is suspended inside the polishing chamber.

[0006] As a further improvement of the above solution, the separation assembly includes an annular frame and a screen, the screen is arranged on the annular frame, and a small hole is opened in the middle of the annular frame, and a sealing rod is inserted into the small hole;

[0007] The bottom end of the sealing rod extends downward to form a widened portion, and the widened portion is placed inside the discharge pipe, and the inner diameter of the discharge pipe and the outer diameter of the widened portion are larger than the inner diameter of the small hole. The widened portion is plugged into the discharge pipe to seal it, so that the polishing sand in the polishing bin will not flow out, and a cross bar can be fixed at the bottom end of the outer ring surface of the polishing bin as needed. The cross bar passes through the sealing rod and fixes it to prevent it from moving up due to vibration.

[0008] As a further improvement of the above scheme, the length of the widened portion is smaller than the height between the middle bottom end of the polishing chamber and the bottom end of the annular frame, and the bottom end of the outer ring surface of the widened portion is recessed upward to form a plurality of notches distributed in a ring shape, and the notches do not penetrate the top of the widened portion. When the widened portion is pulled upward for a certain distance, the notches are placed above the discharge pipe, so that the polishing sand can enter the discharge pipe through the notches and be discharged.

[0009] As a further improvement of the above scheme, the material guide pipe is arranged obliquely on the base, and a hose is provided at one end of the material guide pipe close to the discharge pipe. The material guide pipe is connected to the discharge pipe through the hose. The hose is a water hose or other soft pipe, and is relatively long and in a fluffy state. When the upper material guide pipe is shaken, it will not cause pulling on the lower material guide pipe.

[0010] As a further improvement of the above scheme, a discharge port is provided on the front side of the outer ring surface of the polishing chamber, and a discharge frame is welded on the outward side of the discharge port, and the bottom end of the discharge frame and the bottom end of the discharge port are both flush with the upper surface of the screen, so that the balls inside can be discharged through the discharge port;

[0011] Limiting blocks are arranged on the left and right sides of the discharging frame, and the sealing door is fixed in the discharging frame through the limiting blocks and bolts. The sealing door is opened to facilitate the discharge of the balls inside.

[0012] As a further improvement of the above scheme, the bottom end of the interior of the polishing bin is thickened and inclined to form a material discharge slope. The height of the material discharge slope gradually decreases from the outside to the inside, and the material discharge slope has a conical structure, which is convenient for discharging and collecting the polishing sand inside the polishing bin.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model provides a separation component for separating polishing sand and balls inside the polishing chamber, and a discharge pipe and a guide pipe are provided at the bottom of the polishing chamber, so that the separated polishing sand can be quickly discharged and collected;

[0026] The bottom end of the sealing rod 8 extends downward to form a widened portion, and the widened portion is placed inside the discharge pipe 11, and the inner diameter of the discharge pipe 11 and the outer diameter of the widened portion are larger than the inner diameter of the small hole. The widened portion is plugged into the discharge pipe 11 to seal it, so that the polishing sand in the polishing chamber 1 will not flow out, and a cross bar can be fixed at the bottom end of the outer ring surface of the polishing chamber 1 as needed, the cross bar passes through the sealing rod 8 and fixes it so that it will not move up due to vibration. The sealing rod 8 can also be removed according to actual conditions, and a valve is installed below the discharge pipe 11 to control the discharge.

[0027] The length of the widened portion is smaller than the height between the middle bottom end of the polishing chamber 1 and the bottom end of the annular frame 21, and the bottom end of the outer ring surface of the widened portion is recessed upward to form a plurality of notches distributed in an annular shape, and the notches do not penetrate the top end of the widened portion. When the widened portion is pulled upward for a certain distance, the notches are placed above the discharge pipe 11, so that the polishing sand can enter the discharge pipe 11 through the notches and be discharged.

[0028] The material guide pipe 5 is tiltedly arranged on the base 3, and a hose 51 is provided at one end of the material guide pipe 5 close to the discharge pipe 11. The material guide pipe 5 is connected to the discharge pipe 11 through the hose 51. The hose 51 is a water hose or other soft pipe, and its length is relatively long and in a fluffy state. When the upper material guide pipe 5 is shaken, it will not cause pulling on the lower material guide pipe 5.
