[0024] In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.

[0025] like Figure 1-4 As shown, the utility model provides a metal plate grinding device, including a base 10, a workbench 20 and a pressing assembly 30, and also includes an annular guide rail 40, a slider 50, a grinding assembly 60 and a driving assembly 70.

[0026] The annular guide rail 40 is fixedly installed on the top of the workbench 20 in the transverse direction.

[0027] The slider 50 is disposed on the annular guide rail 40 and is slidably connected to the annular guide rail 40 .

[0028] The grinding assembly 60 includes a guide rod 61, a spring 62, a grinding wheel 63 and a first motor 64. The guide rod 61 is arranged in a transverse direction, the first end of the guide rod 61 is slidably connected to the slider 50, the second end of the guide rod 61 extends toward the center of the annular guide rail 40, and a fixing plate 65 is fixedly installed on the second end of the guide rod 61. The spring 62 is sleeved on the guide rod 61, and the two ends of the spring 62 are respectively fixedly connected to the slider 50 and the fixing plate 65, and the spring 62 makes the fixing plate 65 have a tendency to approach the center of the annular guide rail 40. The grinding wheel 63 is arranged in a transverse direction below the fixing plate 65 and is rotatably connected to the fixing plate 65. The first motor 64 is fixedly installed on the fixing plate 65, used to control the rotation of the grinding wheel 63, and the first motor 64 is electrically connected to the external control cabinet.

[0029] The driving assembly 70 is used to control the sliding block 50 to slide on the annular guide rail 40 .

[0030] Before using the device, the staff first places the metal sheet on the workbench 20, and presses the metal sheet tightly against the workbench 20 through the pressing assembly 30. Under the action of the spring 62, the grinding wheel 63 contacts the side of the metal sheet.

[0031] The specific working process of the device is as follows: the staff controls the first motor 64 and the driving assembly 70 to start simultaneously through the external control cabinet. After the first motor 64 is started, it will drive the grinding wheel 63 to rotate, so as to grind the side of the metal plate in contact. After the driving assembly 70 is started, it will drive the slider 50 to move slowly on the annular guide rail 40, so that the grinding assembly 60 can move synchronously and perform all-round grinding on the side of the metal plate.

[0032] Under the action of the spring 62, no matter what shape the metal plate is, the grinding wheel 63 will always be in close contact with the side of the metal plate, so the device can grind the sides of metal plates of different shapes, and the overall versatility is better.

[0033] In one embodiment, the driving assembly 70 includes an annular rack 71, a second motor 72 and a gear 73. The annular rack 71 is disposed outside the annular guide rail 40 and is fixedly connected to the workbench 20, and the axis of the annular rack 71 is colinear with the axis of the annular guide rail 40. The second motor 72 is fixedly mounted on the slider 50 and is electrically connected to the external control cabinet. The gear 73 is fixedly mounted on the output shaft of the second motor 72 and meshes with the annular rack 71.

[0034] When the external control cabinet controls the driving assembly 70 to start, the second motor 72 drives the gear 73 to rotate. Since the gear 73 is meshed with the annular rack 71 , the slider 50 moves slowly on the annular guide rail 40 .

[0035] The driving assembly 70 has a simple structure, can reduce manufacturing costs, and is convenient to use.

[0036] In one embodiment, a locking assembly 80 is further included, and the locking assembly 80 includes a rotating plate 81 and a locking column 82. The first end of the rotating plate 81 is hinged to the fixed plate 65, and a locking hole 83 is formed on the second end of the rotating plate 81. The locking column 82 is fixedly mounted on the slider 50.

[0037] In the initial state, the locking column 82 is inserted into the locking hole 83, and the spring 62 is in a contracted state, so that the staff can place the metal plate on the workbench 20 for easy operation.

[0038] In one embodiment, the diameter of the locking post 82 is smaller than the diameter of the locking hole 83 , so that the locking post 82 can be more easily inserted into the locking hole 83 .

[0039] In one embodiment, a pressing assembly 30 is further included, and the pressing assembly 30 includes a vertical plate 31, a horizontal plate 32, an electric push rod 33 and a pressing plate 34. The vertical plate 31 is arranged on the outer side of the annular rack 71 and is fixedly connected to the workbench 20. The first end of the horizontal plate 32 is fixedly connected to the vertical plate 31, and the second end of the horizontal plate 32 extends toward the center of the annular guide rail 40. The pressing plate 34 is arranged below the horizontal plate 32 in the horizontal direction. The electric push rod 33 is arranged in the longitudinal direction and is electrically connected to the external control cabinet. The first end of the electric push rod 33 is fixedly connected to the horizontal plate 32, and the second end of the electric push rod 33 is fixedly connected to the pressing plate 34.

[0040] In the initial state, the electric push rod 33 is in a retracted state. After the staff places the metal sheet on the workbench 20, the staff controls the electric push rod 33 to extend through the external control cabinet until the pressing plate 34 presses the metal sheet, so that the metal sheet remains stable, which is convenient for subsequent grinding operations and improves the grinding effect.

[0041] In one embodiment, a rubber pad is fixedly installed at the bottom of the pressing plate 34. The design of the rubber pad can increase the friction between the pressing plate 34 and the metal plate, reducing the shaking of the metal plate; on the other hand, it can prevent the pressing plate 34 from directly contacting the metal plate, thereby protecting the metal plate.

[0042] In one embodiment, the number of the pressing assemblies 30 is three, and the three pressing assemblies 30 are arranged at intervals along the circumference of the annular guide rail 40 .

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.

[0044] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
