Description

Technical Field

[0001] This utility model relates to the technical field of polishing, and in particular to a device for polishing the chamfered edges of car bumpers. Background Technology

[0002] The production process of car bumpers begins with cutting sheet metal to the appropriate size. The cut sheet metal then undergoes processes such as punching, bending, and painting to obtain the bumper. Since there are burrs on the edges of the cut sheet metal, a grinding mechanism is needed to grind and chamfer the edges after cutting to remove the burrs.

[0003] In the prior art, the utility model patent with patent application number 201720827524.7 discloses a sheet metal edge grinding device, which mainly consists of a bracket and a grinding head. When in use, the sheet metal is first fixed, and then the edge of the upper surface of the sheet metal is ground by the grinding head.

[0004] However, the above-mentioned prior art devices have the following problems during use. Since the edges of the upper and lower surfaces of the sheet metal have burrs after being cut, after the upper edge of the sheet metal is polished, the staff still need to manually flip the sheet metal up and down so that the other side of the sheet metal is rotated to the side closer to the polishing head for polishing. Relying on manual flipping of the sheet metal is extremely labor-intensive and inconvenient to use. After a long period of work, the staff's work efficiency is easily reduced. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a car bumper edge chamfering grinding device that can assist workers in flipping the board during the grinding process, reducing labor intensity, improving work efficiency, and is easy to use and highly practical.

[0006] This utility model discloses a car bumper edge chamfering and grinding device, including a base plate; it also includes a grinding machine, a moving mechanism, a fixing mechanism, and a flipping mechanism. A conical grinding roller is provided on the right side of the grinding machine. The grinding machine is mounted on the moving mechanism, which is used to move the grinding machine. The fixing mechanism is mounted on the base plate and has a fixing function. The flipping mechanism is mounted on the upper right side of the base plate and has a flipping function. During the production of the car bumper, after the sheet metal is cut, it is placed on the fixing mechanism, so that one edge of the sheet metal to be ground faces the conical grinding roller. Then, the grinding machine is turned on, causing the grinding machine to drive the conical grinding roller to rotate. The moving mechanism then moves the grinding machine, causing the conical grinding roller to rotate. The roller moves, causing the rotating conical grinding roller to contact the edge of the board, where it grinds and chamfers the edge. Then, a fixing mechanism rotates the board, causing the upper edge of the board to rotate sequentially to the side closest to the conical grinding roller for chamfering. Next, a flipping mechanism rotates the board, flipping the lower edge to the upper edge. The board is then fixed by the fixing mechanism. The conical grinding roller then grinds the un-grinded edges of the upper part of the board in the same manner. After grinding, the board is transferred to the bending and stamping process to be processed into a bumper. This method assists workers in flipping the board during grinding, reducing labor intensity, improving work efficiency, and is convenient and highly practical.

[0007] Preferably, the fixing mechanism includes an electric lifting platform, a lifting plate, a servo indexing turntable A, and an electromagnetic chuck. The electric lifting platform is fixedly installed on the upper end of the base plate, the lifting plate is fixedly installed on the upper end of the electric lifting platform, the servo indexing turntable A is fixedly installed on the upper end of the lifting plate, and the electromagnetic chuck is installed on the rotating end of the upper part of the servo indexing turntable A. The material of the plate is iron. When grinding the plate, the plate is placed on the upper end of the electromagnetic chuck, so that one edge of the electromagnetic chuck faces the conical grinding roller. Then, the electromagnetic chuck is opened to attract and fix the plate. Then, the edge of the plate is ground by the conical grinding roller. The servo indexing turntable A can be opened to make the electromagnetic chuck drive the plate to rotate, so that each edge of the plate rotates sequentially to the side facing the conical grinding roller for grinding. The height of the lifting plate can be adjusted by the electric lifting platform, and the height of the electromagnetic chuck and the plate can be adjusted by the servo indexing turntable A to adjust the height of the plate to a suitable grinding height, which facilitates the adjustment of the plate position and improves convenience.

[0008] Preferably, the moving mechanism includes a linear cross slide module, a moving plate, and a support plate. The linear cross slide module is fixedly installed on the base plate, and the moving plate is provided on the linear cross slide module. The linear cross slide module is used to move the moving plate back and forth and left and right. The support plate is fixedly installed on the upper end of the moving plate, and the grinding machine is fixedly installed on the right end of the support plate. When grinding the board material with the conical grinding roller, the linear cross slide module first drives the moving plate to move to the right, and then the moving plate drives the support plate and the grinding machine to move to the right, so that the conical grinding roller on the grinding machine moves to the right until it contacts the edge of the board material. Then, the linear cross slide module moves the moving plate in the back and forth direction, and the moving plate drives the support plate and the grinding machine to move. The grinding machine drives the rotating conical grinding roller to move in the back and forth direction. During the back and forth movement, the conical grinding roller grinds the front and back parts of the edge of the board material.

[0009] Preferably, the flipping mechanism includes a left-right moving mechanism, a servo indexing turntable B, a pneumatic finger cylinder, and two sets of clamping plates.

The right end of the pneumatic finger cylinder is mounted on the rotating end of the left side of the servo indexing turntable B. The power output end of the left side of the pneumatic finger cylinder is provided with two sets of clamping plates. The left-right moving mechanism is used to move the servo indexing turntable B left and right. When it is necessary to flip the sheet metal up and down, the left-right moving mechanism moves the servo indexing turntable B to the left, which in turn drives the pneumatic finger cylinder to move to the left. The sheet material is positioned between two sets of clamping plates. The pneumatic finger cylinders are then activated, clamping the right side of the sheet material between the clamping plates. The electric lifting platform then lowers the lifting plate, servo indexing turntable A, and electromagnetic chuck to prevent interference with the electromagnetic chuck during sheet material rotation. The servo indexing turntable B is then activated, causing the pneumatic finger cylinders to rotate, which in turn causes the two clamping plates to flip the sheet material up and down. The electromagnetic chuck then rises to contact the sheet material, re-attaching and securing it. Finally, the clamping plates are released, facilitating the flipping of the sheet material.

[0010] Preferably, the left and right moving mechanism includes a linear module, a sliding plate, and a mounting plate. The linear module is fixedly mounted on the base plate, and the sliding plate is provided on the linear module. The linear module is used to move the sliding plate left and right. The mounting plate is fixedly mounted on the upper end of the sliding plate, and the servo indexing turntable B is fixedly mounted on the sliding plate. When moving the servo indexing turntable B left and right, the linear module is opened, causing the sliding plate to move in the left and right direction, thereby driving the mounting plate and the servo indexing turntable B to move in the left and right direction, which facilitates the left and right movement of the servo indexing turntable B.

[0011] Preferably, both sets of clamps are provided with rubber pads; this arrangement avoids damage to the sheet material from the two sets of clamps and improves reliability during use.

[0012] Preferably, the grinder is equipped with a leakage current protector; this feature improves the safety of the grinder during use.
