The movable mold base is slidably installed in cooperation with the installation base plate. Two groups of clamping molds are symmetrically arranged, and the two groups of clamping molds are respectively detachably installed on the opposite surfaces of the fixed mold base and the movable mold base. Two groups of slider structures are symmetrically constructed on both sides of the bottom end of the movable mold base. Two groups of guiding sliding grooves for the sliders to be embedded and slide are symmetrically opened on the upper end surface of the installation base plate. A driving mechanism for driving the movable mold base is installed on one side of the movable mold base away from the fixed mold base. Among them, the driving mechanism drives the movable mold base to move along the extension direction of the guiding sliding groove.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , a steel roller outer circle anti-slip processing tooling in this embodiment, includes a mounting plate 1 and a positioning mechanism 2. The positioning mechanism 2 includes a motor 201. The motor 201 is fixedly installed on the right side of the mounting plate 1, and a fixed disk 203 is fixedly installed on the left side of the upper mounting plate 1. A rotating rod 202 extending to the inner center of the fixed disk 203 is fixedly installed at the output shaft of the motor 201. A cross 204 is fixedly installed inside the fixed disk 203. Four sliding cavities 205 are opened inside the cross 204. A guiding rod 206 is slidably connected inside each of the four sliding cavities 205. Four fixed rods 207 are fixedly installed on the outer surface of the rotating rod 202. A connecting rod 208 is hinged between each of the four fixed rods 207 and the guiding rod 206. A positioning wheel 209 is fixedly installed at one end of each of the four connecting rods 208 away from the guiding rod 206.

[0020] The output shaft of the motor 201 is fixedly connected to the rotating rod 202, the fixed disk 203 is fixedly connected to the mounting plate 1, and the rotating rod 202 is rotatably connected to the fixed disk 203. Therefore, when the motor 201 drives the rotating rod 202 to rotate, the fixed disk 203 will not rotate. By rotating the rotating rod 202, the four fixed rods 207 are driven to rotate, so as to adjust the distance between the four positioning wheels 209.

[0021] The inside of the fixed disk 203 is divided into four accommodation cavities with equal areas by the cross 204. The four accommodation cavities provide an activity space for the four connecting rods 208. One end of each of the four connecting rods 208 is hinged to the fixed rod 207, and the other end is hinged to the connecting rod 208. Therefore, by rotating the four fixed rods 207, the four guiding rods 206 can be driven to move horizontally inside the four sliding cavities 205, so as to adjust the distance between the four positioning wheels 209.

[0022] After changing the distance between the four positioning wheels 209, steel rollers with different inner diameters can be fixed. The outer surfaces of the four positioning wheels 209 are in contact with the inner wall of the steel roller, achieving the fixation of the inner diameter of the steel roller, thereby preventing slipping during the processing, meeting the processing requirements for the outer circle of the steel roller, and solving the problem that the fixture in the above-mentioned utility model patent clamps and fixes the outer side of the steel roller, and when processing the outer surface of the steel roller, the outer surface of the steel roller is blocked, unable to meet the processing requirements for the outer circle.

[0023] Mounting holes are provided at the four corners of the mounting plate 1, and the device is fixed at the using position through the mounting holes. The grinding wheel on the grinding device is in contact with the outer surface of the steel roller for grinding operations.

[0024] During implementation, the following steps are carried out for operation:

[0025] 1) First, fix the device at the using position through the four positioning holes on the mounting plate 1;

[0026] 2) Then, drive the rotating rod 202 to rotate through the motor 201. The rotating rod 202 drives the four fixing rods 207 to rotate. The four fixing rods 207 drive the four connecting rods 208 to rotate, causing the four guide rods 206 to slide horizontally in the corresponding sliding cavities 205, thereby changing the distance between the four positioning wheels 209;

[0027] 3) Then, according to the size of the inner diameter of the steel roller, adjust the four positioning wheels 209 to appropriate positions so that the four positioning wheels 209 are in contact with the inner wall of the steel roller to position the steel roller;

[0028] 4) Finally, the grinding wheel is in contact with the outer surface of the steel roller for grinding. During the grinding process, the rotation of the grinding wheel drives the steel roller to rotate on the four positioning wheels 209, performing all-round grinding on the outer circle of the steel roller.

[0029] In summary, for this anti-slip processing tooling for the outer circle of the steel roller, by setting the positioning mechanism 2, the distance between the four positioning wheels 209 can be adjusted. According to the size of the inner diameter of the steel roller, the inner walls of steel rollers of different sizes are fixed between the four positioning wheels 209, achieving precise positioning and fixation of the steel roller, ensuring the stability and precision of the processing process, thus facilitating the grinding processing of the outer circle of the steel roller. Moreover, during the grinding process, the four positioning wheels 209 can assist the steel roller to rotate, facilitating all-round grinding of the outer circle of the steel roller.
