[0002] During the processing of metal sheets, their surfaces usually need to be polished to remove defects, burrs, rust, etc., making them smooth and improving quality. In our factory, the polishing of round metal sheets is usually done by using an automatic polishing machine to polish the two circular surfaces of the round metal sheet. For the polishing of the curved edge of the round metal sheet, workers need to hold the round metal sheet and make the curved edge of the metal sheet contact the high-speed rotating grinding wheel on the grinding machine, which increases the labor intensity of the workers. Moreover, because the workers are close to the grinding wheel, the dust and debris generated by the grinding wheel can easily cause harm to the workers' health. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a special fixing device for grinding and processing circular metal plates.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

The positioning plate is movably connected between the two mounting plates. The two mounting plates are respectively provided with a first fixing head and a second fixing head. The first fixing head and the second fixing head cooperate to fix the circular metal sheet. A positioning roller is rotatably connected to the positioning plate and abuts against the arc-shaped edge of the circular metal sheet. The motor is fixed on one mounting plate and its output end is connected to the first fixing head. The cylinder is fixed on the other mounting plate and its output end is rotatably connected to the second fixing head.

[0006] Further configured, the first fixing head includes a first fixing plate and a first connecting rod, one end of the first connecting rod is connected to the output end of the motor, and the other end of the first connecting rod is connected to the first fixing plate. The second fixing head includes a second fixing plate and a second connecting rod, one end of the second connecting rod is rotatably connected to the output end of the cylinder, and the other end of the second connecting rod is connected to the second fixing plate. The first fixing plate and the second fixing plate correspond to the two circular surfaces of the circular metal plate, respectively.

[0007] A further configuration is provided, wherein the positioning plate has a movable groove that cooperates with the positioning roller, the positioning roller is rotatably connected in the movable groove, and the positioning roller extends out of the movable groove.

[0008] A further configuration includes a threaded rod rotatably connected to the positioning plate, a threaded tube threadedly connected to the threaded rod, a back plate connected to the threaded tube connecting the two mounting plates, a limit groove on the mounting plate, and a limit block movably connected to the limit groove on the positioning plate.

Detailed Implementation

[0016] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0017] A special fixing device for grinding and processing circular metal sheets includes two mounting plates 1, a motor 2, a cylinder 3, and a positioning plate 4. The positioning plate 4 is movably connected between the two mounting plates 1. The two mounting plates 1 are respectively provided with a first fixing head 5 and a second fixing head 6. The first fixing head 5 and the second fixing head 6 cooperate to fix the circular metal sheet 200. A positioning roller 7 is rotatably connected to the positioning plate 4. The positioning roller 7 abuts against the arc-shaped edge of the circular metal sheet 200. The motor 2 is fixed on one mounting plate 1, and the output end of the motor 2 is connected to the first fixing head 5. The cylinder 3 is fixed on the other mounting plate 1, and the output end of the cylinder 3 is rotatably connected to the second fixing head 6.

[0018] Working principle: First, a circular metal plate 200 is placed between the first fixing head 5 and the second fixing head 6, so that the first fixing head 5 and the second fixing head 6 correspond to the two circular surfaces of the circular metal plate 200 and are located at the center of the circular metal plate 200. At the same time, the arc-shaped edge of the circular metal plate 200 abuts against the grinding wheel 100. The cylinder 3 drives the second fixing head 6 to move towards the first fixing head 5, so that the first fixing head 5 and the second fixing head 6 abut against the two circular surfaces of the circular metal plate 200, thereby clamping and fixing the circular metal plate 200. In conjunction with adjusting the position of the positioning plate 4, the positioning roller 7 rotatably connected to the positioning plate 4 abuts against the arc-shaped edge of the circular metal plate 200, keeping the arc-shaped edge of the circular metal plate 200 in contact with the grinding wheel 100, thus preventing the arc-shaped edge of the circular metal plate 200 from colliding with the grinding wheel. When grinding with 100 contact, the movement of the circular metal plate affects the grinding of the arc-shaped edge of the circular metal plate 200 by the grinding wheel 100. After the circular metal plate 200 is fixed, the motor 2 drives the first fixed head 5 to rotate. The output end of the cylinder 3 is rotatably connected to the second fixed head 6, and the positioning roller 7 is rotatably connected to the positioning plate 4, thereby realizing the rotation of the circular metal plate 200. This allows the high-speed rotating grinding wheel 100 to perform circumferential grinding on the circular metal plate 200, achieving grinding of the arc-shaped edge of the circular metal plate 200. It eliminates the need for the worker to hold the circular metal plate 200 to make contact between the arc-shaped edge of the circular metal plate 200 and the grinding wheel 100 of the grinding machine, reducing the worker's labor intensity. At the same time, it avoids the harm to the worker's health caused by dust and debris generated by the grinding wheel 100 due to the worker being too close to the grinding wheel 100.

[0019] The first fixing head 5 includes a first fixing plate 51 and a first connecting rod 52. One end of the first connecting rod 52 is fixedly connected to the output end of the motor 2, and the other end of the first connecting rod 52 is fixedly connected to the first fixing plate 51. The second fixing head 6 includes a second fixing plate 61 and a second connecting rod 62. One end of the second connecting rod 62 is rotatably connected to the output end of the cylinder 3 through a bearing, and the other end of the second connecting rod 62 is fixedly connected to the second fixing plate 61. The first fixing plate 51 and the second fixing plate 61 correspond to the two circular surfaces of the circular metal plate 200, respectively.

[0020] The cylinder 3 drives the second fixing plate 61 to move closer to the first fixing plate 51 via the second connecting rod 62, so that the first fixing plate 51 and the second fixing plate 61 respectively abut against the two circular surfaces of the circular metal plate 200 to fix the circular metal plate 200. This achieves the purpose of the first fixing head 5 and the second fixing head 6 working together to fix the circular metal plate 200. With the motor 2 driving the first fixing plate 51 to rotate via the first connecting rod 52 and the rotational connection between the output end of the cylinder 3 and the second connecting rod 62, the circular metal plate 200 fixed between the first fixing plate 51 and the second fixing plate 61 rotates under the action of the motor 2.

[0021] The positioning plate 4 has a movable groove 8 that cooperates with the positioning roller 7. The positioning roller 7 is rotatably connected in the movable groove 8 through a bearing, so that the positioning roller 7 can rotate on the positioning plate 4. The positioning roller 7 extends out of the movable groove 8, which makes it easy for the positioning roller 7 to contact and fix the circular metal plate 200 with the arc edge, without affecting the rotation of the circular metal plate 200.

[0022] A threaded rod 9 is rotatably connected to the positioning plate 4, and a threaded tube 10 is threadedly connected to the threaded rod 9. A back plate 11 corresponding to the threaded tube 10 is fixedly connected between the two mounting plates 1. The threaded tube 10 is fixed on the back plate 11. A limit groove 12 is opened on the mounting plate 1, and a limit block 13 that is movably connected to the limit groove 12 is fixedly connected to the positioning plate 4.

[0023] The positioning plate 4 is moved by rotating the threaded rod 9, which is threaded into the threaded tube 10, thereby adjusting its position. This allows the positioning roller 7, which is rotatably connected to the positioning plate 4, to contact the arc-shaped edge of the circular metal plate 200. Simultaneously, the positioning plate 4 is moved to facilitate contact with the arc-shaped edges of circular metal plates 200 of different diameters, enabling the grinding of the arc-shaped edges of the circular metal plates 200 of different diameters and improving practicality. The limiting groove 12 and the limiting block 13 prevent the positioning plate 4 from rotating when the threaded rod 9 rotates, thus avoiding misalignment between the positioning roller 7 and the arc-shaped edge of the circular metal plate 200, which would affect the fixation of the circular metal plate 200, while not affecting the movement of the positioning plate 4.

[0024] Both the first fixing plate 51 and the second fixing plate 61 are connected to elastic pads 14 to prevent wear on the two circles of the circular metal plate 200 when the first fixing plate 51 and the second fixing plate 61 fix the circular metal plate 200, thus affecting the surface smoothness of the circular metal plate 200.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
