[0022] Obviously, many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] See also Figure 1-5 The utility model provides a device for grinding corners of a steel liner for mining, comprising a processing bottom plate 1, both sides of the processing bottom plate 1 are fixedly connected with second side plates 19, the tops of the two second side plates 19 are fixedly connected with first servo electric cylinders 4, the tops of the two first servo electric cylinders 4 are fixedly connected with first side plates 3, a top plate 2 is fixedly connected between the two first side plates 3, the bottom of the top plate 2 is slidably provided with two equipment boxes 5, the bottoms of the two equipment boxes 5 are slidably provided with two grinding tools 6 that can be used for grinding corners of the liner, and the top of the processing bottom plate 1 is equipped with a rotatable clamping steel liner The clamping mechanism is used. When the steel lining is placed on the top of the processing base plate 1, the steel lining is clamped by the clamping mechanism. After that, through the extension and retraction of the two first servo electric cylinders 4 and the two adjustable position equipment boxes 5, the positions of the two grinders 6 respectively arranged at the bottom of the two equipment boxes 5 are aligned with the corners of the steel lining. Then, the corners of the steel lining are grinded by the rotation of the grinder 6, and the corresponding corners on the steel lining are grinded by the rotation of the clamping mechanism. If the size is appropriate, the four corners can be grinded at the same time, thereby improving the grinding efficiency of the steel lining when grinding the corners.

[0024] In order to facilitate the two device boxes 5 to slide at the bottom of the top plate 2 and thus adjust the positions of the four grinders 6, the extension and retraction of the second servo electric cylinder 8 on both sides of the fixed support plate 9 fixedly connected to the bottom of the top plate 2 is used to control the position adjustment of the two device boxes 5. By opening the first motor 7 on the two device boxes 5 and rotating the two first bidirectional threaded rods 11, the position adjustment of the two threaded sleeves 20 inside the two device boxes 5 is driven respectively. At this time, the second motor 10 fixedly connected to the top of the threaded sleeve 20 and the output shaft fixedly connected to the bottom of the second motor 10, as well as the grinder 6 fixedly connected to the bottom of the output shaft, can adjust the positions respectively inside the two device boxes 5, thereby completing the position adjustment of the two grinders 6 at the bottom of the two device boxes 5.

Although both of them pass through the interior of the threaded sleeve 20, the first bidirectional threaded rod 11 is arranged on one side of the first bidirectional threaded rod 11, thereby avoiding mutual influence between the two.

[0027] Furthermore, in order to ensure stable sliding of the two threaded sleeves 20 inside the two device boxes 5, the two sides of the threaded sleeves 20 fit with the two sides of the inner wall of the device box 5, and the two threaded sleeves 20 on the same side are respectively threadedly sleeved on the two ends of the first bidirectional threaded rod 11.
