Description

Technical Field

[0001] The invention relates to the technical field of metal polishing, and in particular to a polishing device for processing parts of numerically controlled machine tools. Background Art

[0002] The bearing ring is a commonly used component for CNC machine tools. The bearing ring is divided into an inner ring and an outer ring, which are assembled to the shaft and the housing respectively. The bearing ring is an important part of the bearing. The main function of the bearing ring is to support and reduce the friction and resistance inside the bearing, and to ensure its rotation accuracy, to ensure that the bearing can work normally, and to maintain its stability and sustainability. The surface of the bearing ring needs to be polished during the production process. The purpose is to remove the tiny bumps, burrs and unevenness on the surface of the bearing ring, so that its surface becomes very smooth, which can not only improve the appearance quality of the bearing ring, but also reduce the friction between the bearing ring and other components, thereby improving the assembly accuracy of the bearing ring and other components and extending the service life of the bearing.

[0003] Chinese patent (CN109676494A) discloses a polishing device for the surface of CNC machine tool parts, including a base, a first fixed plate, a second fixed plate, a motor, a fixed column, a fixed rod, a sliding cavity, a clamping plate, an air pump, a piston, a sliding rod, a connecting plate, a first fixing bolt, a rotating plate, a second fixing bolt, a limit plate, a clamping shell, a connecting rod, a connecting frame, a slide groove, a drain pipe, a first grinding plate, a connecting block, a second grinding plate, a third fixing bolt, an air pipe and a spring, which is convenient for fixing the bearing to be polished as a whole, ensuring that the outer ring of the bearing is stably placed during the polishing process, facilitating the polishing of the bearing surface, increasing the scope of use of the device, and greatly improving the polishing efficiency of the bearing.

[0004] The bearing ring comprises an inner wall and an outer wall, and both the inner and outer walls of the bearing ring need to be polished to ensure the installation accuracy of the bearing ring. The above-mentioned patent fixes the inner wall of the bearing ring and then polishes the outer wall of the bearing ring. Although the outer wall of the bearing ring is polished, the inner wall of the bearing ring also needs to be polished. The above-mentioned patent lacks polishing of the inner wall of the bearing ring and has certain limitations. The inner wall of the bearing ring needs to be polished by additional equipment replacement, which is very troublesome. Moreover, when polishing the bearing ring, only one bearing ring can be clamped and polished at a time, and the bearing rings cannot be polished in batches. The polishing efficiency of the bearing ring is low.

At this time, the positions of the moving block 6 and the baffle 7 in the up and down directions are limited, and the baffle 7 is in a position to block the bearing ring. The position of the bearing ring in the up and down directions is limited, and the screw 18 is rotated clockwise. The screw 18 drives the moving plate 4 to move forward, and the moving plate 4 drives multiple bearing rings to move forward via the fixed shaft 5. When the front end of the bearing ring contacts the polishing wheel 9, the screw 18 is stopped, and the first motor 32 is turned on. The output end of the motor 32 drives the slide 35 to rotate, and the slide 35 drives the rotating shaft 10 to rotate through the first spline, and the rotating shaft 10 drives the polishing wheel 9 to rotate. Since the outer edge of the polishing wheel 9 contacts the outer wall of the bearing ring, the bearing ring rotates with the polishing wheel 9 under the action of friction, and the polishing wheel 9 performs friction polishing on the entire outer wall of the bearing ring. At the same time, the electric telescopic rod 33 is turned on, and the electric telescopic rod 33 drives the protective shell 8 to move up and down, and the protective shell 8 drives the polishing wheel 9 to move up and down. The polishing wheel 9 rotates while moving up and down, and the polishing wheel 9 polishes the outer walls of multiple bearing rings. In this process, due to the action of the support plate 30 and the fifth spring 29, the front side of the inner wall of the bearing ring contacts the fixed shaft 5, so that the front ends of the multiple bearing rings are in the same position. This position can ensure that the polishing wheel 9 contacts the outer wall of the bearing ring. After the polishing of the outer wall of the bearing ring is completed, the first motor 32 and the electric telescopic rod 33 are turned off. The baffle 7 is swung upward by 90° and limited, and the bearing ring is taken out from the fixed shaft 5;

[0050] When it is necessary to polish the inner wall of the bearing ring, multiple bearing rings are placed in the circular groove so that the cylinder 11 is located in the bearing ring. The outer wall of the bearing ring is fixed first, and the T-shaped rod 54 is pulled to move upward and the fourth spring 55 is stretched to make the upper end of the T-shaped rod 54 move out of the limiting hole 53, release the limit on the second rotating ring 48, pull the T-shaped rod 54 to rotate, and the T-shaped rod 54 drives the second rotating ring 48 to rotate clockwise. The second rotating ring 48 drives the first rotating ring 47 to rotate synchronously through multiple connecting rods 52, so that the guide column 51 slides in the guide groove 49, and the guide column 51 drives the multiple cross plates 50 to move toward the center of the cylinder 11. The cross plate 50 drives the multiple clamping plates 17 to move relatively. When the multiple clamping plates 17 clamp the multiple bearing rings, release the T-shaped rod 54, and the T-shaped rod 54 is inserted downward into the corresponding limiting hole 53 under the action of the fourth spring 55. At this time, the bearing ring is coaxial with the cylinder 11. The limit shaft 39 is rotated, and the limit shaft 39 belt drives the rotating drum 37 to rotate and stretch the torsion spring 38 through the second spline. The limit shaft 39 drives the swing plate 43 to swing out of the swing groove 42, releases the limit on the limit shaft 39, and pushes the limit shaft 39 to move downward. The limit shaft 39 drives the round table 12 to move downward through the round block 40. Since the round table 12 is a shape of a large top and a small bottom, the round table 12 pushes the multiple push blocks 15 to move in opposite directions when it moves downward. The push blocks 15 drive the multiple slide bars 13 to move in opposite directions and compress the third spring 44. The slide bar 13 drives the multiple grinding plates 14 to move toward the inner wall of the bearing ring. When the grinding plates 14 contact the inner wall of the bearing ring, they stop pushing the limit shaft 39 to move downward. Under the reset action of the torsion spring 38, the rotating drum 37 is driven to rotate. The rotating drum 37 drives the limit shaft 39 to rotate through the second spline. The limit shaft 39 drives the swing plate 43 to swing into the swing groove 42. At this time, the position of the round table 12 is limited;

[0051] The second motor 45 is turned on, and the second motor 45 drives the transmission shaft 46 to rotate. The transmission shaft 46 drives the cylinder 11 to rotate. The cylinder 11 drives the grinding plate 14 to rotate relative to the bearing ring through the sliding rod 13. When the grinding plate 14 rotates, the inner walls of multiple bearing rings are polished. After the polishing of the inner walls of the bearing rings is completed, the motor is turned off, and the T-shaped rod 54 is pulled upward to stretch the fourth spring 55, so that the upper end of the T-shaped rod 54 moves out of the limiting hole 53, and the limiting of the second rotating ring 48 is released. The T-shaped rod 54 is pulled to rotate, and the T-shaped rod 54 The second swivel 48 is driven to rotate counterclockwise, and the second swivel 48 drives the first swivel 47 to rotate synchronously through multiple connecting rods 52, so that the guide column 51 slides in the guide groove 49, and the guide column 51 drives the multiple cross plates 50 to move in the direction away from the center of the cylinder 11, and the cross plates 50 drive the multiple clamping plates 17 to move in opposite directions. When the multiple clamping plates 17 no longer clamp the bearing ring, the T-shaped rod 54 is released, and the T-shaped rod 54 is inserted downward into the corresponding limit hole 53 under the action of the fourth spring 55 to remove the bearing ring from the circular groove.
