[0030] Driven by the second motor 17, the first movable frame 3 can be driven to slide along the first guide rod 12 through the first lead screw 13 and the first lead screw sleeve 14.

[0031] Please refer to Figure 4 , the second movable frame 4 is sleeved on the bottom of the first movable frame 3 and is in contact with the first movable frame 3, the second driving mechanism 11 includes a second lead screw 18, a second lead screw sleeve 19 adapted to the second lead screw 18 is sleeved on the second lead screw 18, the second lead screw sleeve 19 is rotatably connected to the second movable frame 4, a second worm gear 20 is fixedly connected to the outside of the second lead screw sleeve 19, a second worm 21 adapted to and drivingly connected to the second worm gear 20 is arranged above the second worm gear 20, the second worm 21 is rotatably installed on the second movable frame 4, a third motor 22 is fixedly connected to the end of the second movable frame 4 corresponding to the second worm 21, and the output end of the third motor 22 is fixedly connected to the second worm 21.

[0032] Driven by the third motor 22, the second movable frame 4 is driven to slide on the first movable frame 3 under the cooperation of the second lead screw 18 and the second lead screw sleeve 19.

[0033] Please refer to Figure 5 , a first slide rail 23 is fixedly connected to the side wall of the bottom frame 1, a first slider 24 is slidably connected to the first slide rail 23, a first hand-tightening bolt 25 is threadedly connected to the first slider 24, and one end of the first hand-tightening bolt 25 penetrates through the first slider 24 and abuts against the first slide rail 23.

[0034] A fixed platform 26 is further fixedly connected to the first slider 24, an extrusion plate 27 is arranged above the fixed platform 26, a second guide rod 28 is fixedly connected to the bottom surface of the extrusion plate 27, the second guide rod 28 is inserted into the fixed platform 26 and is slidably connected to the fixed platform 26, and a second hand-tightening bolt 29 is further threadedly connected to the extrusion plate 27, and the bottom end of the second hand-tightening bolt 29 is rotatably connected to the fixed platform 26.

[0035] Thus, the medium-thick plate to be surface-treated can be fixed by the fixed table 26 in cooperation with the pressing plate 27, and it slides along the first slide rail 23 in cooperation with the first slider 24, so as to be suitable for fixing medium-thick plates of different sizes.

[0036] Please refer to Figure 6 , the inner side of the chassis 1 is provided with a first auxiliary mechanism 30, a second auxiliary mechanism 31 and a third auxiliary mechanism 41. The first auxiliary mechanism 30 includes cross bars 32 fixedly connected to the top surface of the chassis 1 at equal intervals, and a first guide wheel assembly 33 is fixedly connected to the cross bars 32.

[0037] The second auxiliary mechanism 31 and the third auxiliary mechanism 41 are symmetrically and staggeredly arranged. The second auxiliary mechanism 31 and the third auxiliary mechanism 41 have the same structure. The second auxiliary mechanism 31 includes a triangular frame 34, a second guide wheel assembly 35 is fixedly connected to the top surface of the triangular frame 34, and a connecting rod 39 is fixedly connected to the front side of the triangular frame 34 together.

[0038] The upper and lower parts of the triangular frame 34 are both slidably penetrated by third guide rods 36. Both ends of the third guide rods 36 are fixedly connected to the chassis 1. A second slide rail 37 is provided at the top of the triangular frame 34, and a second slider 38 adapted to it is slidably connected to the second slide rail 37. The second slider 38 is fixedly connected to the top surface of the chassis 1.

[0039] A third hand-tightening bolt 40 is threadedly connected to the triangular frame 34 corresponding to the third guide rod 36. The third hand-tightening bolt 40 penetrates the triangular frame 34 and abuts against the third guide rod 36.

[0040] Thus, the chassis 1 can be extended by the second auxiliary mechanism 31 and the third auxiliary mechanism 41 to form loading and unloading platforms on both sides of the chassis 1, which is convenient for loading and unloading. At the same time, the medium-thick plate placed above the chassis 1 can be supported by hand and pushed in cooperation with the first guide wheel assembly 33 and the second guide wheel assembly 35 to move the position of the medium-thick plate, so as to adapt to the processing of medium-thick plates with a larger area.

[0041] The working principle of the present invention is: When in use, the second auxiliary mechanism 31 and the third auxiliary mechanism 41 can be pulled by the connecting rod 39, so as to pull the tripod 34. The tripod 34 slides through the third guide rod 36, and the second slide rail 37 slides synchronously within the second slider 38, so that the tripod 34 is pulled out. Then, the third hand-tightening bolt 40 is rotated so that the third hand-tightening bolt 40 abuts against the third guide rod 36 to form a fixing effect. At this time, the medium-thick plate to be surface-treated can be placed on the second auxiliary mechanism 31, and is pushed to the first guide wheel assembly 33 on the base frame 1 and close to the fixing table 26 through the cooperation of the second guide wheel assembly 35. At this time, the position of the fixing table 26 is adjusted by adjusting the position of the first slider 24 on the first slide rail 23, so that the fixing table 26 is aligned with the edge of the medium-thick plate. Then, the first hand-tightening bolt 25 is rotated so that the first slider 24 is locked. Then, the second hand-tightening bolt 29 is further rotated, and under the action of the second guide rod 28, the pressing plate 27 descends, so that the medium-thick plate is squeezed and fixed by the cooperation of the pressing plate 27 and the fixing table 26. At this time, the electric push rod 6 is started, and the movable plate 5 descends until the grinding head 9 is attached to the medium-thick plate. At this time, the first motor 7 is further started, and the grinding head 9 is driven to rotate by the rotating shaft 8. Then, the second motor 17 and the third motor 22 are started. At this time, the second motor 17 drives the first worm 16 to rotate, and the first worm 16 drives the first lead screw sleeve 14 to rotate through the first worm gear 15. Thus, under the cooperation of the first lead screw 13, the first movable frame 3 slides along the first guide rod 12. The third motor 22 drives the second worm 21 to rotate, and the second worm 21 drives the second lead screw sleeve 19 to rotate through the second worm gear 20. The second lead screw sleeve 19 drives the second movable frame 4 to move on the first movable frame 3 in the cooperation of the second lead screw 18, so as to move the position of the grinding head 9, thereby forming a surface grinding and polishing effect. Then, the squeezing and fixing effect of the fixing table 26 and the pressing plate 27 on the medium-thick plate can be released. At this time, the medium-thick plate can be pushed towards the third auxiliary mechanism 41, so as to facilitate the removal of the medium-thick plate. During the processing, for a relatively large medium-thick plate, the medium-thick plate is directly placed on the unfolded first auxiliary mechanism 30 and the second auxiliary mechanism 31, and then the medium-thick plate is moved through the cooperation of the first guide wheel assembly 33 and the second guide wheel assembly 35. The part of the medium-thick plate exceeding the top frame 2 is pushed below the top frame 2, so that the processing of a relatively large area of the plate can be carried out.

[0042] The above are only embodiments of the present invention, and common knowledge such as specific structures and characteristics known in the solutions is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
