The right end of the output shaft of the motor 7 is fixedly connected to the left end of the rotating shaft 8. The input end of the motor 7 is electrically connected to the output end of the control switch 2;

[0027] Inner support clamping mechanism 5: It is arranged at the right end of the rotating shaft 8. The inner support clamping mechanism 5 includes a support plate 51, a sliding bracket 52 and an inner support frame 53. The support plate 51 is fixedly connected to the right end of the rotating shaft 8. The right side surface of the support plate 51 is slidably connected with evenly distributed sliding brackets 52. The right side surfaces of the sliding brackets 52 are fixedly connected with inner support frames 53 respectively. The inner support clamping mechanism 5 further includes a threaded connection cylinder 54, a sliding connection frame 55 and a connecting rod 59. The threaded connection cylinder 54 is fixedly connected to the middle of the right side surface of the support plate 51. The outer surface of the threaded connection cylinder 54 is slidably connected with a sliding connection frame 55. The outer surface of the sliding connection frame 55 is fixedly connected with evenly distributed support plates. The front and rear side surfaces of the support plates are rotatably connected with left and right symmetric connecting rods 59 respectively. The upper ends of the connecting rods 59 are rotatably connected with the adjacent ends of the adjacent inner support frames 53 respectively. The inner support clamping mechanism 5 further includes a screw rod 56 and a rotating support plate 57. The right end of the sliding connection frame 55 is fixedly connected with a rotating support plate 57. The screw rod 56 is rotatably connected inside the rotating support plate 57. The left end of the screw rod 56 is threadedly connected with the inside of the threaded connection cylinder 54. The inner support clamping mechanism 5 further includes a knob 58. The right end of the screw rod 56 penetrates through the right side surface of the rotating support plate 57. The right end of the screw rod 56 is fixedly connected with a knob 58. Rubber friction pads 15 are fixedly connected to the opposite side surfaces of the inner support frames 53. During the use process, the staff places the crossed rollers to be corrected on the outer surface of the whole formed by the inner support frames 53. Then the staff rotates the knob 58. The rotation of the knob 58 drives the screw rod 56. The screw rod 56 rotates and is threadedly connected with the inside of the threaded connection cylinder 54. The leftward movement of the screw rod 56 drives the sliding connection frame 55 to move leftward. The leftward movement of the sliding connection frame 55 makes the connecting rod 59 apply a thrust to the inner support frame 53 along its own direction. As a result, the inner support frames 53 move away from each other. The mutual separation of the inner support frames 53 drives the sliding brackets 52 to be slidably connected inside the support plate 51. Thus, the inner walls of the crossed rollers are internally supported by the mutual separation of the inner support frames 53, so as to clamp and lock the crossed rollers. Crossed rollers of various sizes can be locked, and they can be installed quickly;

[0028] Guide rail 9: It is arranged at the right end of the upper surface of the workbench 1. A sliding support seat 11 is slidably connected inside the guide rail 9. A lead screw 10 is rotatably connected between the front and rear walls of the guide rail 9. The outer surface of the lead screw 10 is threadedly connected with the inside of the sliding support seat 11. The front end of the lead screw 10 penetrates through the front side surface of the guide rail 9. The front end of the lead screw 10 is fixedly connected with a turntable 14;

[0029] Wherein: It further includes a support frame 12. The support frame 12 is fixedly connected to the upper surface of the sliding support seat 11. A grinding wheel 13 is fixedly connected to the upper right side surface of the support frame 12.

[0030] The working principle of a cross-roller trimmer provided by the present utility model is as follows: During use, the staff places the cross-roller to be corrected on the outer surface of the overall structure formed by the inner support frame 53. Then, the staff rotates the knob 58. The rotation of the knob 58 drives the screw rod 56. The screw rod 56 rotates and is threadedly connected to the internal thread of the threaded connection cylinder 54. The leftward movement of the screw rod 56 drives the sliding connection frame 55 to move leftward. The leftward movement of the sliding connection frame 55 causes the connecting rod 59 to exert a thrust on the inner support frame 53 along its own direction, so that the inner support frames 53 move away from each other. The mutual separation of the inner support frames 53 drives the sliding support 52 to slide inside the support plate 51. Thus, the inner walls of the cross-roller are internally supported by the mutual separation of the inner support frames 53, and the cross-roller is clamped and locked. Cross-rollers of various sizes can be locked, and they can be quickly installed. Then, the staff starts the motor 7 by adjusting the control switch 2. The operation of the motor 7 drives the rotation of the rotating shaft 8. The rotation of the rotating shaft 8 drives the rotation of the support plate 51. The rotation of the support plate 51 drives the rotation of the cross-roller. Then, the staff rotates the turntable 14. The rotation of the turntable 14 drives the rotation of the lead screw 10. The rotation of the lead screw 10 drives the sliding support base 11 to move back and forth under the limiting action. The back-and-forth movement of the sliding support base 11 drives the support frame 12 to move back and forth. The back-and-forth movement of the support frame 12 drives the grinding wheel 13 to move back and forth. The grinding wheel 13 moves backward, so that the grinding wheel 13 contacts the cross-roller. The feed amount of trimming the cross-roller is adjusted by the moving amplitude of the grinding wheel 13.

[0031] It should be noted that the motor 7 disclosed in the above embodiments can be selected as YS6334, and the control switch 2 is provided with a control button corresponding to the motor 7 and used to control its switch.

[0032] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
