The grinding machine includes a grinding head located outside the operating table, used to grind the outer edges of several steel plates. However, the grinding head in this device has a fixed mounting position, making it difficult to better fit steel plates of different widths for grinding. Furthermore, the angle between the grinding head and the side edge of the steel plate is not adjustable, thus preventing the processing of chamfers at specific angles according to customer requirements, resulting in poor applicability of the grinding device.

[0026] See Figures 1 to 3 A steel plate grinding device includes: a frame 100, a first mounting frame 110 movably mounted on the frame 100, a drive mechanism connected to the first mounting frame 110, a second mounting frame 120 rotatably mounted on the first mounting frame 110, a grinding roller 130 for grinding the steel plate being provided on the second mounting frame 120, the grinding roller 130 being connected to a driver for rotating the roller, the second mounting frame 120 including a rotating shaft 121, one end of the rotating shaft 121 being connected to a gear 122, the gear 122 meshing with a rack 123, the rack 123 being movably mounted on the first mounting frame 110, the first mounting frame 110 being provided with a limiting mechanism for restricting the movement of the rack 123, when the rack 123 moves relative to the frame 100, the gear 122 rotates to adjust the grinding angle of the grinding roller 130 relative to the steel plate.

[0027] In the steel plate grinding device with the above structure, during use, the rack 123 is moved according to the required shape of the side of the steel plate to be ground, driving the gear 122 to rotate the rotating shaft 121, causing the second mounting bracket 120 to rotate and adjust the angle between the grinding roller 130 and the side of the steel plate. Then, a limiting mechanism is used to lock the position of the rack 123 after movement, thereby fixing the mounting angle of the second mounting bracket 120 relative to the first mounting bracket 110. Finally, a drive mechanism is used to drive the first mounting bracket 110 to move, so that the grinding roller 130 can move and fit against the side of the steel plate to be processed, thereby facilitating the driver to drive the grinding roller 130 to rotate and grind the steel plate. Through the above structure, the grinding position of the grinding roller 130 is adjusted by the first mounting bracket 110, and the grinding angle of the grinding roller 130 is changed by the second mounting bracket 120, thereby better matching steel plates of different widths or involving chamfering grinding, and improving the applicability of steel plate grinding.

[0028] See Figures 1 to 3 Furthermore, the first mounting bracket 110 includes two mounting plates 111 arranged opposite to each other, and the second mounting bracket 120 includes a rectangular frame 124. The two opposite side walls of the rectangular frame 124 are respectively provided with rotating shafts 121. Each mounting plate 111 is provided with a through hole that rotatably engages with the rotating shaft 121. A gear 122 is provided on one of the rotating shafts 121, thereby facilitating the rotational installation of the second mounting bracket 120 relative to the first mounting bracket 110.

[0029] See Figures 1 to 3 Furthermore, the limiting mechanism includes a first mounting hole in the rack 123, and a plurality of second mounting holes 112 are provided at horizontal intervals on a mounting plate 111. The first mounting hole and one of the second mounting holes 112 are connected by a pin 113. Specifically, when it is necessary to adjust the grinding angle of the grinding roller 130, the pin 113 is removed, and then the rack 123 is moved to a suitable position to adjust the mounting angle of the mounting frame relative to the first mounting bracket 110. Finally, a suitable second mounting hole 112 is selected to align with the first mounting hole, and the pin 113 is reinstalled to restrict the rack 123 from moving again, which facilitates quick fixation of the rack 123 after movement. It is understood that the first mounting hole can be replaced with a threaded hole, and the pin 113 can be replaced with a bolt that mates with the threaded hole, thereby improving the stability of locking the rack 123.

[0030] See Figures 1 to 3 Furthermore, one of the mounting plates 111 is provided with a side extension plate 114, which has a horizontally oriented groove 115. The lower part of the rack 123 slides in the groove 115, thereby facilitating the movement of the rack 123 relative to the mounting plate 111. In some embodiments, the mounting plate 111 is provided with a bolt rod, and the rack 123 is provided with a waist-shaped hole through which the bolt rod can pass. The waist-shaped hole extends horizontally, and one end of the bolt rod is connected to a nut, thereby using the nut to restrict the rack 123 from disengaging from the mounting plate 111, which is beneficial for the engagement of the rack 123 with the gear 122.

[0031] See Figures 1 to 3 Furthermore, the driver is a first motor 131 set in the rectangular frame 124. The output end of the first motor 131 is connected to the grinding roller 130. The axis of the rotating shaft 121 intersects with the axis of the grinding roller 130, so that the first motor 131 drives the grinding roller 130 to rotate, which is beneficial to better grind the side of the steel plate.

[0032] See Figures 1 to 3 Furthermore, the driving mechanism includes a second motor 140 mounted on the frame 100. The output end of the second motor 140 is connected to a screw 141, which is arranged horizontally. A slider 116 is mounted on the first mounting bracket 110. The slider 116 is threadedly engaged with the screw 141. A guide mechanism is provided between the slider 116 and the frame 100 to restrict the rotation of the slider 116. Specifically, in use, the second motor 140 drives the screw 141 to rotate, causing the slider 116 to move along the length of the screw 141 under the action of the thread, thereby facilitating the movement of the grinding roller 130 to the side of the steel plate.

[0033] See Figures 1 to 3Furthermore, the frame 100 includes two opposing side plates 101, each side plate 101 having a support plate 102 connected to its lower end, and a cross plate 103 connecting the upper ends of the two side plates 101. A second motor 140 is mounted on one of the side plates 101. The guiding mechanism includes guide rods 142 mounted on the two side plates 101, with the guide rods 142 parallel to the screw 141. A slider 116 is slidably engaged with the guide rods 142. Specifically, in use, the engagement of the guide rods 142 and the slider 116 helps to restrict the rotation of the slider 116, thereby facilitating translation of the slider 116 relative to the screw 141, which in turn allows the subsequent grinding roller 130 to better grind the steel plate. The guiding mechanism can also be replaced by a combination of a slide rail and a convex strip; the specific structure is not detailed here.

[0034] See Figures 1 to 3 Furthermore, the screw 141 includes two threaded sections with opposite threads, each threaded section corresponding to a slider 116. Each slider 116 is connected to a first mounting bracket 110, and each first mounting bracket 110 is rotatably mounted with a second mounting bracket 120. Each second mounting bracket 120 is correspondingly mounted with a grinding roller 130. Specifically, in use, the second motor 140 drives the two threaded sections to rotate, thereby causing the two sliders 116 to move closer or further apart, thus synchronously adjusting the displacement of the two grinding rollers 130, which is beneficial for synchronously grinding the two sides of the steel plate.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
