[0023] Example 1

[0024] A multi-directional automatic steel plate grinding machine, such as Figures 1 to 3 As shown, it includes at least three grinding mechanisms. Each grinding mechanism includes a frame 1, a drive component 2, a grinding assembly, and a mounting plate 4.

[0025] The frame 1 is fixedly installed on the ground or workbench. The mounting plate 4 is slidably mounted on the frame 1 or hinged to the frame 1, and the grinding assembly is mounted on the mounting plate 4. The drive unit 2 is mounted on the frame 1, and the drive unit 2 is connected to and drives the mounting plate 4 to move linearly back and forth or to rotate the mounting plate 4 until the grinding wheel 32 of the grinding assembly contacts or disengages from the steel plate 40.

[0026] The grinding assembly includes a motor 31, a grinding wheel 32, a drive shaft 33, and a transmission component 34. Both the motor 31 and the grinding wheel 32 are mounted on the mounting plate 4. The motor 31 is fixedly mounted on the mounting plate 4, while the grinding wheel 32 is rotatably mounted on the mounting plate 4 via the drive shaft 33. Specifically, the drive shaft 33 is rotatably mounted on the mounting plate 4 via a bearing and a bearing housing. One end of the drive shaft 33 is connected to the motor 31 via the transmission component 34, and the other end is connected to the grinding wheel 32. The grinding wheel 32 is fitted onto the drive shaft 33.

[0027] In this embodiment, the transmission component 34 is a synchronous belt. A synchronous pulley is fixedly connected to one end of the drive shaft 33, and a synchronous pulley is also connected to the motor shaft of the motor 31. The transmission component 34 is tensioned and fitted onto the two synchronous pulleys. When the motor 31 starts and drives the motor shaft to rotate, the drive is transmitted to the drive shaft 33 through the transmission component 34, causing the drive shaft 33 to rotate, which in turn drives the grinding mold 32 to rotate. Clearly, the drive shaft 33 is the central axis of the grinding mold 32.

[0028] When the mounting plate 4 is slidably mounted on the frame 1, the grinding mechanism also includes at least two guide rods 5. The guide rods 5 are fixedly or rotatably mounted on the frame 1. Specifically, the guide rods 5 do not directly contact the surface of the frame 1, but are positioned at a certain distance from it. The guide rods 5 are mounted on the frame 1 via two bases at both ends, with the two bases fixed to the frame 1 at intervals. The two ends of the guide rods 5 are respectively mounted on the two bases. The guide rods 5 pass through the mounting plate 4, allowing the mounting plate 4 to slide along the guide rods 5. Similarly, at least two brackets can be fixedly connected to the mounting plate 4, through which the guide rods 5 pass. This allows the mounting plate 4 to move along the length of the guide rods 5. The driving component 2 connects to and drives the mounting plate 4 to reciprocate linearly, thereby causing the entire grinding assembly to move synchronously in a linear fashion.

[0029] Preferably, two guide rods 5 are provided, which are arranged in parallel and spaced apart. Each guide rod 5 passes through at least one bracket on the mounting plate 4, so that the mounting plate 4 can only move along the length of the guide rod 5.

[0030] When the mounting plate 4 is hinged to the frame 1, the grinding mechanism also includes a rotating shaft 6, with the mounting plate 4 and the frame 1 hinged to the rotating shaft 6. The cylinder of the drive component 2 is mounted on the frame 1, and the drive shaft of the drive component 2 is connected to the mounting plate 4. The drive component 2 drives the mounting plate 4, causing the mounting plate 4 to rotate relative to the frame 1 around the rotating shaft 6. Specifically, the rotating shaft 6 can rotate on its own or be fixedly mounted on the frame 1. When the rotating shaft 6 is rotatably mounted on the frame 1 via bearings, the mounting plate 4 is fixedly connected to the rotating shaft 6 via connectors. When the rotating shaft 6 is fixedly mounted on the frame 1, the mounting plate 4 is rotatably sleeved on the rotating shaft 6 via bearings.

[0031] In this embodiment, the driving component 2 is a lifting cylinder.

[0032] Of the grinding mechanisms, at least one is a left grinding mechanism 10, at least one is a right grinding mechanism 20, and at least one is an upper grinding mechanism 30. The left grinding mechanism 10 is used to grind the left side of the steel plate 40, the right grinding mechanism 20 is used to grind the right side of the steel plate 40, and the upper grinding mechanism 30 is used to grind the upper surface of the steel plate 40. The left and right sides of the steel plate 40 are two opposite sides of the steel plate 40. The upper surface of the steel plate 40 is adjacent to both the left and right sides of the steel plate 40.

[0033] In this embodiment, the central axis of the grinding wheel 32 of the left grinding mechanism 10 and the central axis of the grinding wheel 32 of the right grinding mechanism 20 are both perpendicular to the plane on the upper surface of the steel plate 40, and the central axis of the grinding wheel 32 of the upper grinding mechanism 30 is perpendicular to the plane on the left side and the plane on the right side of the steel plate 40.

[0034] The grinding wheel 32 of the left grinding mechanism 10 can be moved to contact the left side of the steel plate 40 or to disengage from the left side of the steel plate 40. The grinding wheel 32 of the right grinding mechanism 20 can be moved to contact the right side of the steel plate 40 or to disengage from the right side of the steel plate 40. The grinding wheel 32 of the upper grinding mechanism 30 can be raised or lowered to contact the upper surface of the steel plate 40 or to disengage from the upper surface of the steel plate 40.

[0035] As shown above, the left grinding mechanism 10 and the right grinding mechanism 20 are located on the left and right sides of the steel plate 40, respectively. Preferably, the grinding wheels 32 of the left grinding mechanism 10 and the right grinding mechanism 20 are arranged symmetrically. The grinding wheel 32 of the upper grinding mechanism 30 is located above the steel plate 40.

[0036] When there are two or more left grinding mechanisms 10, each left grinding mechanism 10 is arranged at intervals along the conveying direction of the steel plate 40. Similarly, when there are two or more right grinding mechanisms 20, each right grinding mechanism 20 is arranged at intervals along the conveying direction of the steel plate 40.

[0037] In this embodiment, each upper grinding mechanism 30 is mounted on the frame 1 of a left grinding mechanism 10 or the frame 1 of a right grinding mechanism 20.

[0038] In this embodiment, there are two left grinding mechanisms 10, two right grinding mechanisms 20, and one upper grinding mechanism 30.

[0039] In this embodiment, the mounting plates 4 of the left grinding mechanism 10 and the right grinding mechanism 20 reciprocate linearly, while the mounting plate 4 of the upper grinding mechanism 30 is rotatable. That is, the grinding components of the left grinding mechanism 10 and the right grinding mechanism 20 can reciprocate linearly, and the grinding component of the upper grinding mechanism 30 can rotate around the rotation axis 6. The guide rods 5 of the left grinding mechanism 10 and the right grinding mechanism 20 are both perpendicular to the plane containing the left and right sides of the steel plate 40.

[0040] In this embodiment, both the left grinding mechanism 10 and the right grinding mechanism 20 are equipped with counterweights (not shown in the figure) for counterbalancing the grinding components. Specifically, the counterweights are installed on the mounting plate 4 by means of hoisting or other methods, thus ensuring that the force between the grinding wheel 32 and the steel plate 40 remains constant when the grinding wheel 32 is grinding the steel plate 40. This is equivalent to the counterweights applying a uniform force to the grinding wheel 32, ensuring that the grinding wheel 32 is in close contact with the steel plate 40.

[0041] Based on the above structure, the working principle and process of this utility model are as follows: The steel plate 40 to be ground is driven by the conveying mechanism to be conveyed in a straight line in the horizontal plane. The driving component 2 of the left grinding mechanism 10 drives the grinding assembly to move linearly until the grinding wheel 32 of the left grinding mechanism 10 contacts the left side of the steel plate 40. The grinding wheel 32 of the left grinding mechanism 10 rotates to grind the left side of the steel plate 40. The driving component 2 of the right grinding mechanism 20 drives the grinding assembly to move linearly until the grinding wheel 32 of the right grinding mechanism 20 contacts the right side of the steel plate 40. The grinding wheel 32 of the right grinding mechanism 20 rotates to grind the right side of the steel plate 40. The driving component 2 of the upper grinding mechanism 30 drives the grinding assembly to rotate until the grinding wheel 32 of the upper grinding mechanism 30 descends to contact the upper surface of the steel plate 40. The grinding wheel 32 of the upper grinding mechanism 30 rotates to grind the upper surface of the steel plate 40. After grinding is completed, each drive component 2 drives the grinding assembly to move in the opposite direction to disengage from the steel plate 40.

[0042] Finally, it is necessary to state that the above embodiments are only used to further illustrate the technical solution of this utility model in detail, and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made by those skilled in the art based on the above content of this utility model shall fall within the scope of protection of this utility model.
