Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and more specifically, to a high-efficiency polishing device for curved surfaces of metal parts. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical processes to reduce the roughness of a workpiece surface, thereby obtaining a bright and smooth surface. It involves using polishing tools and abrasive particles or other polishing media to refine the surface of a workpiece. Polishing does not improve the dimensional or geometric accuracy of a workpiece; rather, its purpose is to achieve a smooth surface or a mirror-like finish.

[0003] Existing polishing methods mostly involve manually holding the metal product and moving it back and forth while the polishing wheel rotates. This method is more suitable for polishing straight surfaces. However, for tubular metal workpieces, since the surface is curved, hand-holding will cause inconsistent polishing in different areas. When the hand shakes, it will affect the quality of the polishing by the craftsman, making it difficult to ensure the consistency of polishing effect in different areas of the curved surface. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a high-efficiency polishing equipment for curved surfaces of metal parts, which has the advantage of improving the polishing effect of cylindrical curved surfaces.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency polishing device for curved surfaces of metal parts, comprising a worktable, a movable component mounted on the top of the worktable, the movable component including a support plate fixedly connected to the top of the worktable, a movable motor fixedly connected to the front of the support plate, a lead screw fixedly connected to the output shaft of the movable motor, a movable block threaded onto the outer side of the lead screw, a drive component mounted on the front of the top of the movable block, a mounting plate fixedly connected to the back of the top of the movable block, a retainer fixedly connected to the right side of the mounting plate, a rotating ring mounted on the front of the retainer, an adjustment component mounted on the right side of the inner side of the rotating ring, and a polishing mechanism mounted on the side of the adjustment component away from the inner wall of the rotating ring.

[0006] As a preferred embodiment of this utility model, the driving assembly includes a rotary motor fixedly connected to the top of the moving block, a drive gear fixedly connected to the output shaft of the rotary motor, and annular teeth arranged around the outer side of the rotating ring, the annular teeth meshing with the drive gear.

[0009] As a preferred embodiment of this utility model, a support plate is fixedly connected to the bottom right side of the fixing plate, a worm gear is installed on the top of the support plate, and a handle block is fixedly connected to the front of the worm gear.

[0010] As a preferred embodiment of this utility model, positioning tubes are fixedly connected to the top and bottom of the right side of the fixing plate, and positioning rods are movably sleeved on the inner side of the positioning tubes. The right side of the positioning rods is fixedly connected to the left side of the polishing mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model comprises a moving component, a driving component, a rotating ring, and a polishing mechanism.

Under the threaded thrust of the lead screw, the moving block moves back and forth along the outer side of the lead screw, allowing the polishing mechanism to comprehensively polish the curved surface of the workpiece. This achieves automated polishing, improves the smoothness of the polish, eliminates the need for manual handling of the workpiece, making polishing safer and avoiding the problem of hand tremors affecting the polishing effect during manual polishing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a high-efficiency polishing device for curved surfaces of metal parts, including a worktable 1. A moving component 2 is installed on the top of the worktable 1. The moving component 2 includes a support plate 201 fixedly connected to the top of the worktable 1. A moving motor 202 is fixedly connected to the front of the support plate 201. A lead screw 203 is fixedly connected to the output shaft of the moving motor 202. A moving block 204 is threaded onto the outer side of the lead screw 203. A drive component 3 is installed on the front of the top of the moving block 204. A mounting plate 4 is fixedly connected to the back of the top of the moving block 204. A retainer 5 is fixedly connected to the right side of the mounting plate 4. A rotating ring 6 is installed on the front of the retainer 5. An adjustment component 7 is installed on the right side of the inner side of the rotating ring 6. A polishing mechanism 8 is installed on the side of the adjustment component 7 away from the inner wall of the rotating ring 6.

[0023] In this embodiment, the clamping mechanism for fixing cylindrical metal parts is a common prior art, and will not be described in detail in this application and in the accompanying drawings. After the workpiece is fixed, rotating the handle block 707 drives the worm gear 706 to rotate. Through the meshing of the worm gear 706 and the cylindrical gear 704, the threaded column 702 is driven to rotate. Under the thread thrust of the threaded column 702, the threaded tube 703 drives the polishing mechanism 8 to move to the right, so that the polishing belt of the polishing mechanism 8 is in contact with the surface of the workpiece with appropriate pressure. Then, the polishing mechanism 8 is started to polish, and at the same time, the rotary motor 301 is started to drive the drive. The rotating gear 302 rotates, and through its meshing with the ring gear 601, it drives the rotating ring 6 to rotate, thereby causing the polishing belt of the polishing mechanism 8 to polish the workpiece around its perimeter. The moving motor 202 is turned on, driving the lead screw 203 to rotate. Under the thread thrust of the lead screw 203, the moving block 204 moves back and forth along the outer side of the lead screw 203, thereby enabling the polishing mechanism 8 to perform comprehensive polishing on the curved surface of the workpiece, achieving automated polishing, improving the smoothness of the polishing, eliminating the need for manual handling of the workpiece, making polishing safer, and avoiding the problem of hand tremors affecting the polishing effect during manual polishing.

[0024] The drive assembly 3 includes a rotary motor 301 fixedly connected to the top of the moving block 204. The output shaft of the rotary motor 301 is fixedly connected to a drive gear 302. Annular teeth 601 are provided around the outer periphery of the rotating ring 6, and the annular teeth 601 mesh with the drive gear 302.

[0025] The rotary motor 301 is started, which drives the drive gear 302 to rotate. Through the meshing action with the ring gear 601, the rotating ring 6 is driven to rotate, which in turn causes the polishing belt of the polishing mechanism 8 to polish the periphery of the cylindrical curved surface.

[0026] The retainer 5 includes a fixing ring 501 fixedly connected to the right side of the mounting plate 4. Positioning rollers 502 are installed around the front of the fixing ring 501. Annular roller grooves are opened around the back of the rotating ring 6. The positioning rollers 502 are located inside the annular roller grooves.

[0027] The positioning roller 502 plays a positioning role for the rotating ring 6. When the rotating ring 6 rotates, the positioning roller 502 rolls against the inner wall of the annular roller groove. The friction is small, which makes the rotation process of the rotating ring 6 smooth.

[0028] The adjusting component 7 includes a fixed plate 701 fixedly connected to the inner wall of the rotating ring 6. A threaded post 702 is movably sleeved on the side of the fixed plate 701. A threaded tube 703 is threadedly sleeved on the right side of the threaded post 702. The right side of the threaded tube 703 is fixedly connected to the left side of the polishing mechanism 8. A support plate 705 is fixedly connected to the bottom right side of the fixed plate 701. A worm gear 706 is installed on the top of the support plate 705. A handle block 707 is fixedly connected to the front of the worm gear 706. A cylindrical gear 704 is fixedly sleeved on the left side of the threaded post 702. The worm gear 706 and the cylindrical gear 704 mesh with each other.

[0029] Rotating the handle block 707 drives the worm gear 706 to rotate. Through the meshing of the worm gear 706 and the cylindrical gear 704, the threaded column 702 is driven to rotate. Under the thread thrust of the threaded column 702, the threaded tube 703 drives the polishing mechanism 8 to move to the right or left, thereby enabling the polishing mechanism 8 to polish the curved surfaces of cylindrical workpieces of different diameters.

[0030] The top and bottom of the right side of the fixing plate 701 are fixedly connected to the positioning tube 708. The positioning tube 708 is movably sleeved with the positioning rod 709. The right side of the positioning rod 709 is fixedly connected to the left side of the polishing mechanism 8. The cooperation between the positioning tube 708 and the positioning rod 709 plays a role in fixing the polishing mechanism 8.

[0031] Working principle and usage process of this utility model:

[0032] After the workpiece is fixed, the handle block 707 is rotated to drive the worm gear 706 to rotate. Through the meshing of the worm gear 706 and the cylindrical gear 704, the threaded column 702 is driven to rotate. Under the threaded thrust of the threaded column 702, the threaded tube 703 drives the polishing mechanism 8 to move to the right, so that the polishing belt of the polishing mechanism 8 is in contact with the surface of the workpiece with appropriate pressure. Then the polishing mechanism 8 is started to polish. At the same time, the rotary motor 301 is started to drive the drive gear 302 to rotate. Through the meshing of the ring gear 601, the rotating ring 6 is driven to rotate, and then the polishing belt of the polishing mechanism 8 polishes the workpiece around its perimeter. The moving motor 202 is turned on to drive the lead screw 203 to rotate. Under the threaded thrust of the lead screw 203, the moving block 204 moves back and forth along the outer side of the lead screw 203, so that the polishing mechanism 8 can polish the curved surface of the workpiece comprehensively, realizing automated polishing, improving the smoothness of polishing, eliminating the need for manual handling of the workpiece, making polishing safer, and avoiding the problem of hand tremors affecting the polishing effect during manual polishing.
