Description

Technical Field

[0001] The invention belongs to the technical field of workpiece polishing, and in particular relates to a workpiece polishing device for synchronous internal and external polishing. Background Art

[0002] Polishing refers to the use of mechanical, chemical or electrochemical methods to reduce the roughness of the workpiece surface to obtain a bright and smooth surface. It mainly uses polishing tools and abrasive particles or other polishing media to modify the workpiece surface. The internal and external polishing of cylindrical workpieces is mainly completed manually.

[0003] In the prior art, the gearbox cover is positioned and polished, which has the following disadvantages:

[0004] 1. At present, for the internal and external polishing of cylindrical workpieces, when the external tooling clamps the workpiece, the clamped position will be incompletely polished. At the same time, the existing cylindrical workpiece has low polishing efficiency, which is not convenient for internal and external synchronous polishing;

[0005] 2. Currently, a large amount of dust is generated during the polishing of metal workpieces. This dust will be inhaled into the lungs, and long-term accumulation will lead to respiratory diseases such as pneumoconiosis. Summary of the invention

[0006] The purpose of the present invention is to provide a workpiece polishing device for synchronous internal and external polishing, which has the advantages of improving polishing efficiency, increasing polishing completeness, and reducing the impact of dust on workers.

[0007] The above-mentioned technical purpose of the present invention is achieved through the following technical solutions: a workpiece polishing equipment with synchronous internal and external polishing, including a clamping mechanism, the clamping mechanism includes a base, a clamping assembly and a moving assembly, the clamping assembly includes a moving shell one and a moving shell two, the moving assembly includes a rotating motor one, the rotating motor one is fixedly connected to the inside of the base, the top of the base is provided with a polishing mechanism, the polishing mechanism includes a polishing shell and a polishing assembly, the polishing assembly includes a polishing wheel one and a polishing wheel two, the top of the polishing shell is provided with a dust removal mechanism, the dust removal mechanism includes a dust removal shell, a rotating assembly, a reciprocating assembly and a dust collecting assembly, the dust removal shell includes an outer shell, the rotating assembly includes a hollow rod, the hollow rod is fixedly connected to the top of the polishing shell and is rotatably connected to the outer shell.

[0008] By adopting the above technical scheme, when polishing a cylindrical workpiece, the operation of the clamping assembly is preferably driven by the operation of the rotating motor 1, and the outer clamping member and the inner clamping member are adjusted to the center position of the entire stroke, and then the cylinder is placed outside the top of the base. At this time, the inner clamping member will be located inside the cylinder, and the outer clamping member will be located outside the cylinder. In the initial polishing, the height of the moving shell 2 is preferably adjusted by the moving assembly, so that the inner clamping member moves to the inside of the base. At this time, the outer clamping member provides a clamping force for the cylinder, and the polishing wheel 1 contacts the inner wall of the cylinder in the initial state. In the initial state, the polishing wheel 2 will be away from the outer wall of the cylinder to cooperate with the cylinder to achieve clamping and fixing. The operation of the electric telescopic rod 2 will preferentially adjust the polishing wheel 2 to contact the outer wall of the cylinder. Subsequently, the operation of the rotating motor 2 will realize the self-rotation of the polishing wheel 1 and the polishing wheel 2, and the rotating assembly realizes the rotation of the polishing shell. While the polishing wheel 1 and the polishing wheel 2 are in contact with the inner and outer walls of the cylinder respectively, they realize the movement trend of moving around the center of the cylinder to achieve the effect of uniform polishing of the inside of the cylinder. The operation of the longitudinal moving mechanism will change the height of the polishing wheel 1 and the polishing wheel 2. When the polishing wheel 1 and the polishing wheel 2 come to the bottom of the cylinder, the state of the outer clamping part and the inner clamping part will be switched through the setting of the clamping assembly and the moving assembly, so that the outer clamping part returns to the inside of the base without contacting the outer wall of the cylinder, and the inner clamping part moves to the top of the base without contacting the inner wall of the cylinder. After the longitudinal stroke is completed, the screw is rotated again so that the inner clamping part can achieve an outward clamping force on the inner wall of the cylinder. The polishing wheel 1 and the polishing wheel 2 can be cloth wheels or wool wheels. When the polishing wheel 2 contacts the outer clamping part and the polishing wheel 1 contacts the inner clamping part, there will be no friction damage to the polishing wheel 1 or the polishing wheel 2 due to the contact. This setting will facilitate the completeness of the polishing of the cylinder workpiece, distinguish the inconvenience of polishing the existing clamping contact points, and at the same time, through the setting of the polishing wheel 1 and the polishing wheel 2, the high efficiency of polishing the inside and outside of the cylinder can be achieved, which brings efficiency to the production of the workshop. During the polishing process of the workpiece, the dust polished by the polishing wheel 1 and the polishing wheel 2 will be collected by the dust collecting component through the use of the reciprocating component. The dust inlet opening of the dust removal mechanism changes with the position of the polishing wheel 1 and the polishing wheel 2, ensuring that the dust can be quickly collected after initially leaving the surface of the workpiece, reducing the probability and range of dust drifting in the air. At the same time, the power source relies on the rotating motor 3, and the polishing wheel 1 and the polishing wheel 2 are rotated and polished at the same time to perform synchronous dust removal, increase synchronization, reduce the tedious maintenance of multiple drive devices, and bring cleanliness to the workshop environment, reducing the hidden dangers of respiratory diseases caused by long-term inhalation of dust by workers.

Gear 1027 and screw 1025 are rotated, so that threaded block 1026 drives outer clamp 1023 and inner clamp 1024 to move respectively, wherein the movement directions of outer clamp 1023 and inner clamp 1024 are opposite, guide rod 10210 cooperates with the movement of outer clamp 1023 and inner clamp 1024 to guide, and both outer clamp 1023 and inner clamp 1024 are adjusted to the center position of the entire stroke, and then the cylinder is placed on the top of base 101, at this time, inner clamp 1024 will be located inside the cylinder, and outer clamp 1023 will be located outside the cylinder. During the initial polishing, the height of the moving shell 1022 is adjusted by the electric telescopic rod 1038 first. When the electric telescopic rod 1038 is retracted, the moving shell 1022 moves longitudinally, wherein the sliding connection between the guide rod 10310 and the guide block 10311 will respectively cooperate with the movement of the moving shell 1021 and the moving shell 1022 for guidance. At the same time, the longitudinal movement of the moving shell 1022 will synchronously drive the screw 1025, the support frame 1034, the bevel gear 1027, the bevel gear 1028 and the moving ring 1035 to move synchronously. At this time, the mutual locking of the clamping strip 1036 and the clamping groove 1037 The connection will enable the moving ring 1035 to move smoothly on the surface of the connecting rod 1029, and the moving ring 1035 and the connecting rod 1029 to rotate synchronously. At this time, the inner clamping member 1024 will move to the inside of the base 101, and the outer clamping member 1023 will approach each other and provide a clamping force for the cylinder through the rotation of the screw 1025. The polishing wheel 1 2021 will contact the inner wall of the cylinder in the initial state, and the polishing wheel 2022 will be away from the outer wall of the cylinder in the initial state to cooperate with the cylinder to achieve clamping and fixation. The operation of the electric telescopic rod 20214 will give priority to adjusting the polishing wheel 2022 to contact the outer wall of the cylinder.During the operation of the electric telescopic rod 20214, the support frame 2029, the bevel gear 5 2027, the shifting ring 20210 and the polishing wheel 2022 will be driven to move laterally.

When the polishing wheel 1 2021 and the polishing wheel 2 2022 come to the bottom of the cylinder, the state of the outer clamping member 1023 and the inner clamping member 1024 is switched through the reverse operation of the electric telescopic rod 1038 and the rotating motor 1031, so that the outer clamping member 1023 returns to the inside of the base 101 without contacting the outer wall of the cylinder, and the inner clamping member 1024 moves to the top of the base 101 without contacting the inner wall of the cylinder. After the longitudinal stroke is completed, the screw 1025 is rotated again so that the inner clamping member 1024 can achieve an outward clamping force on the inner wall of the cylinder. The polishing wheel 1 2021 and the polishing wheel 2 2022 can be cloth wheels or wool wheels. When the polishing wheel 2 2022 contacts the outer clamping member 1023, the polishing wheel 1 2021 contacts the inner clamping member 1024, and the contact does not cause the polishing wheel 1 2021 or the polishing wheel 2 2022 to cause friction and damage.This arrangement will facilitate the complete polishing of the cylindrical workpiece, and eliminate the inconvenience of polishing the existing clamping contact points. At the same time, through the arrangement of polishing wheel 1 2021 and polishing wheel 2 22, high-efficiency polishing of the inside and outside of the cylindrical body can be achieved, bringing efficiency to the production of the workshop.
