[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media.

[0003] However, in practical applications, most existing tube and shell parts are usually polished by workers using handheld polishing machines. However, during the manual polishing process, the workers have different polishing pressures, which will lead to certain differences in the degree of polishing. Moreover, the manual polishing operation is relatively inefficient, which will lead to a waste of some time and is not conducive to promotion and use.

[0004] Therefore, those skilled in the art provide a tube shell parts polishing device to solve the problems raised in the above background technology. Utility Model Content

At this time, the two limit rods 4 cooperate with each other to squeeze and limit the tube shell part, and at the same time, the tube shell part can be in a centered position. The output shaft of the motor 2 cooperates with the sprocket 8 and the chain 9 to drive the reciprocating screw 6 to rotate. The rotation of the reciprocating screw 6 can drive the grinding ring 7 to reciprocate up and down. At the same time, the output shaft of the motor 2 drives the tray 3 to rotate, and the tray 3 cooperates with the limit rod 4 to drive the tube shell part to rotate. The grinding ring 7 performs up and down contact grinding on the tube shell part in the rotating state. Compared with the manual grinding method, it can not only ensure the uniformity of grinding, but also improve the grinding efficiency, save time, and is conducive to popularization and use.

[0020] In the present application, a plurality of balls 10 are movably mounted on the top side of the base plate 1, and the plurality of balls 10 are in contact with the bottom side of the tray 3; by setting the balls 10, the plurality of balls 10 cooperate with each other to support the tray 3 in a rotating state, thereby improving the stability of the tray 3 during rotation.

[0021] In the present application, two square rods 11 are fixedly connected to the top side of the base plate 1, and the grinding ring 7 is slidably sleeved with the two square rods 11; by setting the square rods 11, when the grinding ring 7 moves up or down, the two square rods 11 cooperate with each other to enable the grinding ring 7 to maintain vertical movement and avoid deviation.

[0022] In the present application, four limiting rollers 12 are rotatably connected to the bottom side of the base plate 1, and the four limiting rollers 12 are in contact with the chain 9; by setting the limiting rollers 12, the four limiting rollers 12 cooperate with each other to limit the chain 9, thereby ensuring that the chain 9 can have a sufficient wrap angle with the three sprockets 8 for transmission at the same time.

[0023] In the present application, rubber blocks 13 are fixedly connected to the outer sides of the two limit rods 4. By providing the rubber blocks 13, when the limit rods 4 contact the inner wall of the placed tube shell part, the rubber blocks 13 can increase the friction between the two, and at the same time, prevent the limit rods 4 from causing scratches on the inner wall of the tube shell part.

[0024] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0025] The implementation principle of a tube shell part polishing device in the embodiment of the present application is as follows: when in use, the tube shell part is placed on the tray 3, and the bidirectional screw rod 5 is twisted. When the bidirectional screw rod 5 rotates, it drives the two limit rods 4 to move relative to each other until the two limit rods 4 are in contact with the inner wall of the tube shell part. At this time, the two limit rods 4 cooperate with each other to squeeze and limit the tube shell part, and at the same time, the tube shell part can be in a centered position. The output shaft of the motor 2 cooperates with the sprocket 8 and the chain 9 to drive the reciprocating screw rod 6 to rotate. The rotation of the reciprocating screw rod 6 can drive the grinding ring 7 to reciprocate up and down. At the same time, the output shaft of the motor 2 drives the tray 3 to rotate, and the tray 3 cooperates with the limit rod 4 to drive the tube shell part to rotate. The grinding ring 7 performs up and down contact grinding on the tube shell part in the rotating state, which is more convenient than manual. The dynamic grinding method can not only ensure the uniformity of grinding, but also improve the grinding efficiency, save time, and is conducive to promotion and use. Multiple balls 10 cooperate with each other to support the tray 3 in a rotating state, thereby improving the stability of the tray 3 when rotating. When the grinding ring 7 moves up or down, the two square rods 11 cooperate with each other to keep the grinding ring 7 moving in the vertical direction to avoid deviation. The four limit rollers 12 cooperate with each other to limit the chain 9, thereby ensuring that the chain 9 can simultaneously have a sufficient wrap angle with the three sprockets 8 for transmission. When the limit rod 4 contacts the inner wall of the placed tube shell part, the rubber block 13 can increase the friction between the two, and at the same time, avoid the limit rod 4 from scratching the inner wall of the tube shell part.
