[0007] Specifically in the utility model, the adjustment structure includes a slot, which extends inward from one end of the main adjustment wall close to the auxiliary adjustment wall. The auxiliary adjustment wall is slidably matched with the slot. After the auxiliary adjustment wall is inserted into the slot, it is locked by a locking piece.

[0008] In order to lock the main adjustment wall and the auxiliary adjustment wall, the locking part includes two locking columns symmetrically fixed on the waist of the auxiliary adjustment wall front and back, and long grooves are opened on the front and rear sides of the main adjustment wall. The long grooves pass through the slot inward, and the locking column extends out through the long grooves and is locked by a lock nut. The locking column is a threaded column, and the lock nut is a nut threadedly installed on the locking column, and the nut is pressed against the side of the main adjustment wall.

[0009] Compared with the prior art, the utility model has the following beneficial effects: two grinding wheels grind the two sides of the steel plate at the same time, thereby improving the grinding efficiency; the main adjusting wall and the auxiliary adjusting wall can adjust the distance between the two grinding wheels to cope with steel plates of different widths; the inclination angle between the two grinding wheels can also be adjusted to cope with the sides of different steel plates, thereby making the grinding wheels more applicable.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] like Figure 1-2 As shown, the utility model provides a grinder for removing oxide scale from the surface of a steel plate, including an adjusting connecting frame, a mounting plate 1 is vertically fixed at both ends of the adjusting connecting frame, a horizontally placed motor 2 is fixed on the opposite surfaces of the two mounting plates 1, a grinding wheel 3 is fixed at the free end of the output shaft of the motor 2, the adjusting connecting frame includes a main adjusting wall 4 and a secondary adjusting wall 5, the ends of the main adjusting wall 4 and the secondary adjusting wall 5 that are close to each other are connected by an adjusting structure, the two mounting plates 1 are respectively fixed on the ends of the main adjusting wall 4 and the secondary adjusting wall 5 that are away from each other, here, the motor 2 and the grinding wheel 3 can be replaced as a whole into a small angle grinder.

[0017] like Figure 3 As shown, in the utility model, the adjustment structure specifically includes a slot 4-1, which extends inward from one end of the main adjustment wall 4 close to the auxiliary adjustment wall 5, and the auxiliary adjustment wall 5 is slidably matched with the slot 4-1. After the auxiliary adjustment wall 5 is inserted into the slot 4-1, it is locked by a locking piece.

[0018] like Figure 2-3 As shown, in order to achieve the locking of the main adjustment wall 4 and the auxiliary adjustment wall 5, the locking member includes two locking columns 5-1 symmetrically fixed to the waist of the auxiliary adjustment wall 5 front and back, and long grooves 4-2 are opened on the front and rear sides of the main adjustment wall 4. The long grooves 4-2 penetrate the slot 4-1 inwardly, and the locking column 5-1 extends out through the long grooves 4-2 and is locked by the lock nut 5-2. The locking column 5-1 is a threaded column, and the lock nut 5-2 is a nut threadedly installed on the locking column 5-1, and the nut is pressed against the side of the main adjustment wall 4.

[0019] like Figure 4 As shown, the working principle of the utility model is described in detail below: after the steel plate M is flame cut, it is placed on the ground, and the nut is unscrewed from the threaded column. At this time, the auxiliary adjustment wall 5 can slide in the slot 4-1 and the long groove 4-2, driving the threaded column to slide. If the side of the steel plate M is inclined, it is necessary to rotate the auxiliary adjustment wall 5, and the threaded column rotates in the long groove 4-2. The relative movement of the auxiliary adjustment wall 5 and the main adjustment wall 4 changes the distance between the two grinding wheels 3, and the auxiliary adjustment wall 5 and the main adjustment wall 4 can change the inclination angle of the two grinding wheels 3, so as to cope with different steel plates M. After the adjustment is completed, the nut is screwed on the threaded column until the nut is pressed against the side of the main adjustment wall 4 to achieve locking between the main adjustment wall 4 and the auxiliary adjustment wall 5. The two grinding wheels 3 are clamped on the two side edges of the steel plate M. Moving the entire adjustment connecting frame can drive the grinding wheels 3 to move along the side edges of the steel plate M. The motor 2 is connected to an external power supply to drive the grinding wheels 3 to rotate, thereby grinding the oxide scale on the side edges of the steel plate M.

[0020] Compared with the prior art, the utility model has the following beneficial effects: the two grinding wheels 3 grind the two side edges of the steel plate M at the same time, thereby improving the grinding efficiency; the main adjustment wall 4 and the auxiliary adjustment wall can adjust the distance between the two grinding wheels 3 to cope with steel plates M of different widths; and the inclination angle between the two grinding wheels 3 can be adjusted to cope with the side edges of different steel plates M, thereby making the grinding wheels 3 more applicable.

[0021] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
