Description

Technical Field

[0001] The utility model relates to the technical field of metal part polishing, in particular to a polishing device for disc-shaped metal parts. Background Technique

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical actions to reduce the surface or side roughness of disc-shaped metal parts to obtain a bright and flat surface. Currently, the polishing machines in use usually use polishing wheels as polishing parts. The polishing wheel is generally made of multiple layers of canvas, felt or leather stacked together and clamped by metal round plates on both sides. The polishing agent evenly mixed with fine abrasive and grease is coated on its rim. During polishing, the high-speed rotating polishing wheel presses against the workpiece, so that the abrasive produces rolling and micro-cutting on the workpiece surface, thereby obtaining a bright processed surface.

[0003] Currently, when workers perform polishing treatment, they generally use a hand-held polishing machine to polish disc-shaped metal parts one by one. Since the number of disc-shaped metal parts to be polished is generally large, when using a hand-held polishing machine to polish disc-shaped metal parts, the polishing labor intensity is large. In addition, when polishing the side of the metal part, the worker needs to adjust the running direction of the polishing wheel or the direction of the metal part many times, resulting in a large labor intensity of the worker and low work efficiency. Content of the Utility Model

[0004] To achieve the above object, the utility model provides the following technical solution: A polishing device for disc-shaped metal parts, including an operating table and a turntable installed on the operating table, as well as a feeding component, a grinding component and an auxiliary rotation component installed around the turntable.

[0005] The placing component includes a plurality of fixing plates fixed on the turntable. Two rotating parts are installed on the fixing plates, and suction cups are installed on the tops of the rotating parts;

[0006] The auxiliary rotation component includes an L-shaped plate fixed on the operating table. A forward push cylinder is installed on the L-shaped plate, and a belt driving device slidably connected and fixed to the ejecting end of the forward push cylinder. A driving wheel that can be attached to the two rotating parts is installed at the rotating end of one end of the belt driving device.

A belt transmission group is installed between the two rotating cylinders, and a rotating wheel that can be attached to the driving wheel is fixed at the bottom of the rotating cylinder.

[0008] Further, the pressing-down assembly includes vertical frames fixed on the turntable and distributed oppositely with the same number as the fixed plates, and an upward-pushing cylinder located below the vertical frames. The ejecting end of the upward-pushing cylinder passes through the vertical frames and is fixed with a U-shaped plate. Follow-up blocks are rotatably connected to both ends of the U-shaped plate. Two guiding rods fixed to the U-shaped plate are inserted through the vertical frames.

[0009] Further, the feeding assembly includes two feeding plates and two upward-pushing cylinders fixed on the operating table. A lead screw device is installed on the feeding plate. The lifting end of the lead screw device is fixed with a tray that slides on the feeding plate. A servo motor is installed at the top end of the upward-pushing cylinder. A rotating plate is fixed to the rotating end of the servo motor. A lifting plate is arranged on the rotating plate. A suction block is installed at the bottom of the lifting plate.

[0010] Further, a buffer baffle that can be attached to the lifting plate is fixed between the two upward-pushing cylinders.

[0011] Further, a U-shaped column plate is fixed to the top of the rotating plate. The lifting plate is slidably connected to the two columns of the U-shaped column plate. Springs located above the lifting plate are sleeved on the outer sides of the two columns.

[0012] Further, the grinding assembly includes a top frame fixed on the operating table and located above the L-shaped plate. Two fixed columns are fixed to the top of the top frame.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0015] For this disc-shaped metal part polishing device, the feeding assembly can automatically adsorb and place the disc-shaped metal part onto the placing and supporting assembly for positioning. Then, the turntable drives the disc-shaped metal part to move below the grinding assembly. The metal is pressed down by the pressing-down assembly. At the same time, the auxiliary rotating assembly moves and closely adheres to the rotating part of the supporting assembly.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 , a disc-shaped metal part polishing device in this embodiment includes an operating table 1, a turntable 2 is installed on the tabletop of the operating table 1, and a feeding component 5, an auxiliary rotation component 7 surrounding the turntable 2 and a grinding component 6 located above the auxiliary rotation component 7 are fixed. A plurality of placing components 3 that can move to the lower sides of the grinding component 6 and the feeding component 5 are fixed on the turntable 2, and a lower pressing component 4 with the same number as the placing component 3 is installed, and the lower pressing component 4 is opposite to the placing component 3, and the lower pressing end is located above the placing component 3.

[0025] In the above structure, the loading component can automatically transfer the disc-shaped metal part to the supporting component for placement, and the supporting component is driven by the turntable to move and adjust the direction. Then, the pressing component cooperates with the supporting component to press down and position the metal part until the metal part moves to the bottom of the grinding component. At this time, the auxiliary rotating component is pushed forward and tightly attached to the supporting component. Therefore, with the cooperation of the pressing component and the auxiliary rotating component, the supporting component can be limited to prevent the grinding component from rotating when grinding the metal part. At the same time, through the cooperation of the auxiliary rotating component and the pressing component, the supporting component can drive the metal part to rotate and adjust the direction, so as to automatically complete the side grinding of the metal part. Therefore, it is suitable for mass production through automation, and it can also reduce the workload of workers and improve production efficiency.

[0026] like Figure 2 In the direction shown, the holding assembly 3 includes six rectangular fixed plates 301 fixed on the turntable 2, two bearings 302 are installed on the fixed plates 301, a rotating drum 303 passing through the turntable 2 is fixed on the inner side of the bearing 302, a belt transmission group 304 is connected between the outer sides of the two rotating drums 303, a rotating wheel 305 that can be attached to the rotating end of the auxiliary rotating assembly 7 is fixed at the bottom of the rotating drum 303, and a suction cup 306 located below the lower pressing end of the lower pressing assembly 4 is fixed at the top of the rotating drum 303. The product to be polished can be transferred to the suction cup through the feeding assembly, and the metal part is adsorbed and positioned by the suction cup. After positioning is completed, the lower pressing assembly can also press the metal part on the suction cup to prevent the metal part from shifting during grinding, and the auxiliary rotating assembly can be tightly limited with the rotating wheel to prevent the suction cup from rotating during grinding, and then the two rotating drums can be driven to rotate under the transmission of the auxiliary rotating assembly, so as to drive the metal part to rotate and complete the side grinding process.

[0027] like Figure 4 In the direction shown, the loading assembly 5 includes two loading plates 501 fixed on the operating table 1 and distributed relatively front to back, and two lifting cylinders 504 installed on the operating table 1 and located between the two loading plates 501, a screw device 502 is installed on the loading plate 501, and a tray 503 sliding with the loading plate 501 is fixed at the lifting end of the screw device 502, a servo motor 505 is installed on the top of the lifting cylinder 504, a rotating plate 506 is fixed at the rotating end of the servo motor 505, a lifting plate 509 is installed on the rotating plate 506, the lifting plate 509 is L-shaped, and a suction block 510 is installed at the bottom end of the lifting plate 509, and the suction block 510 can be vertically symmetrical with the tray 503. The tray holds the stacked disc-shaped metal parts, and the servo motor drives the turn plate to rotate, so that the suction block is opposite to the metal parts. At the same time, the upper cylinder moves through the turn plate to contact the metal parts, so that the suction block absorbs the metal parts and transfers them to the suction cup, thereby completing the automatic loading operation.

[0028] Wherein, a buffer baffle that can be attached to the lifting plate 509 is fixed between the two upper top cylinders 504. When the servo motor drives the suction block to move upward to the suction cup through the rotating plate and the lifting plate, the lifting plate will be attached to the buffer baffle, thereby playing a limiting role to prevent the rotation from exceeding the limit.

[0029] In addition, a U-shaped column plate 507 is fixed to the top of the rotating plate 506, and the lifting plate 509 is sleeved between the two columns of the U-shaped column plate 507. Springs 508 are sleeved on the outer sides of the two columns and are located above the lifting plate 509. When the upper top cylinder drives the rotating plate to move downward and the metal part is placed on the suction cup through the suction block, when the downward pressure is too large, the lifting plate can be driven by the suction block to move upward to squeeze the spring, thereby playing a buffering role.

[0030] As Figure 3 Shown in the direction, the downward pressing assembly 4 includes vertical frames 401 that are fixed on the turntable 2 and have the same number as the fixing plates 301 and are distributed oppositely, and upper pushing cylinders 402 installed below the vertical frames 401. The ejecting ends of the upper pushing cylinders 402 pass through the vertical frames 401 and are fixed with U-shaped plates 403. Follow-up blocks 405 are rotatably connected to both ends of the U-shaped plates 403. The follow-up blocks 405 are vertically symmetrically distributed with the suction cups 306. Guide rods 404 are arranged on the vertical frames 401 on both sides of the upper pushing cylinders 402, and the tops of the two guide rods 404 are fixed to the U-shaped plates 403. When the metal part is adsorbed on the suction cup, at the same time, the upper pushing cylinder drives the U-shaped plate to move up and down, and the guide rods can be cooperated to improve the stability of the up and down movement of the U-shaped plate. Therefore, the follow-up block can be driven to be closely attached to the metal part to complete the pressing operation. At the same time, when the suction cup rotates, the follow-up block can also rotate accordingly.

[0031] As Figure 6 Shown in the direction, the auxiliary rotation assembly 7 includes an L-shaped plate 701 fixed on the operation table 1. A front pushing cylinder 702 is installed at the protruding end of the L-shaped plate 701. A belt driving device 703 fixed to the ejecting end of the front pushing cylinder 702 is also slidably connected to the L-shaped plate 701. A driving wheel 704 that is located between the two rotating wheels 305 and can be attached to each other is installed at the bottom of the left rotating end of the belt driving device 703. When the turntable moves the metal part below the grinding assembly, the front pushing cylinder drives the belt driving device to push forward, so that the driving wheel is closely attached between the two rotating wheels, playing a limiting role on the two rotating wheels. At the same time, the belt driving device can drive the driving wheel to rotate. Because the driving wheel is closely attached to the rotating wheel, the rotating wheel can be driven to rotate together. Therefore, the suction cup can be driven to rotate to adjust the direction of the metal part.

[0032] As Figure 5For the shown direction, the grinding assembly 6 includes a top frame 601 fixed on the operation table 1. The top frame 601 is located above the L-shaped plate 701. Two fixing columns 602 are installed on the top of the top frame 601. A linear module 603 and a slider 604 located below the linear module 603 are fixed on the outer side of the fixing column 602. A moving plate 605 that slides with the currently lower slider 604 is fixed on the moving end of the linear module 603. A downward push cylinder 606 is installed on the top of the moving plate 605. The ejecting end of the downward push cylinder 606 is fixed to a downward push plate 610 that slides with the moving plate 605. A driving motor 607 is installed on the top of the downward push plate 610. The rotating end of the driving motor 607 is fixed to a rotating column 608 that penetrates through the downward push plate 610. A grinding wheel 609 is installed at the bottom of the rotating column 608. The linear module can drive the moving plate to move in opposite or away directions, so that the distance between the grinding wheel and both sides of the metal part can be adjusted according to requirements. Therefore, the downward push cylinder can drive the downward push plate to move downward, so that the metal part is located between the two grinding wheels. By adjusting the movement of the moving plate through the linear module, the grinding wheel can be made to adhere to both sides of the metal part. Then the driving motor drives the rotating column to rotate, and the edge side of the metal part is polished by the grinding wheel.

[0033] The working principle of the above embodiment is as follows:

[0034] The servo motor drives the rotating plate to rotate, so that the suction block is located above the metal part. Then the upward push cylinder operates to drive the suction block to adhere to and adsorb the metal part. Then it resets and transfers the metal part to be placed above the suction cup. At the same time, the lead screw device drives the tray to move upward progressively, so that the uppermost metal part reaches the best adsorption position. Then the suction cup adsorbs and positions the metal part. Therefore, the feeding operation of two groups of metal parts can be completed simultaneously. At this time, the upward push cylinder operates, and the follower block is driven by the U-shaped plate to press the metal part tightly. The turntable rotates, driving the metal part to be located below the grinding wheel. At this time, the forward push cylinder drives the belt driving device to move, so that the driving wheel is located between the rotating wheels and is closely attached to the limit. Then the downward push cylinder drives the downward push plate to move downward, so that the metal part is located between the two grinding wheels. Then the linear module drives the moving plate to move, so that both grinding wheels are attached to the edge sides of the two metal parts. Then the driving motor drives the rotating column to rotate, so that the grinding wheel polishes the metal part. During the processing, the belt driving device drives, driving the driving wheel to rotate. The driving wheel is attached to the rotating wheel, so that the two rotating wheels can be driven to rotate simultaneously. The rotating wheel drives the turntable to rotate through the rotating cylinder. At the same time, the follower block will also follow, completing the direction adjustment of the metal part, so that the edge side of the metal part is polished evenly.

[0035] In summary, it can realize the automatic polishing process of the disc-shaped metal parts, reduce the labor intensity of workers, be applicable to mass production, and improve the production efficiency.

[0036] The entire workflow is completed, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
