[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a hand-cranked grinder clamping device, comprising an electromagnet workbench 1, a mounting plate 2 is placed on the lower surface of the electromagnet workbench 1, and both ends of the electromagnet workbench 1 and the mounting plate 2 are threadedly connected with a No. 1 bolt 3, with the help of the No. 1 bolt 3, the connection and fixation between the electromagnet workbench 1 and the mounting plate 2 are facilitated, and at the same time, the No. 1 bolt 3 is threadedly connected to the movable table on the hand-cranked grinder, which facilitates the installation of the electromagnet workbench 1 and the mounting plate 2 on the hand-cranked grinder, a movable groove is provided on the mounting plate 2, and a screw rod 4 is rotatably connected in the movable groove, one end of the screw rod 4 is fixedly connected with a connecting rod, and the connecting rod is connected to the mounting plate 2 through and fixedly connected with a torsion disk 5 at one end, the rotation of the screw rod 4 is conveniently controlled with the help of the torsion disk 5, a movable plate 6 is threadedly connected to the screw rod 4, and the movable plate 6 is slidably connected in the movable groove, and hollow sleeve plates 7 are provided at both ends of the movable plate 6, and the hollow sleeve plates 7 are slidably connected with movable The movable plate 8 changes the clamping and fixing point of the clamping and fixing plate 9 by moving the movable plate 8 up and down, so that the clamping and fixing plate 9 can be moved accordingly according to workpieces of different heights, thereby improving the stability of their clamping and fixing. One end of the movable plate 8 is fixedly connected with a clamping and fixing plate 9. The movable plate 6, the hollow sleeve plate 7 and the clamping and fixing plate 9 are linked by the rotation of the screw rod 4 to make the two clamping and fixing plates 9 move toward the center of the electromagnet worktable 1, so that the metal workpiece is stably clamped and the stability of the metal workpiece during processing is improved. A clamping block 11 is penetrated on one side of the hollow sleeve plate 7, and the clamping block 11 is engaged with the movable plate 8. With the help of the clamping block 11, it is convenient to fix the movable plate 8 after moving in the hollow sleeve plate 7. A square groove is provided on the clamping and fixing plate 9, and a push plate 12 is movably connected in the square groove. A receiving plate is fixedly connected between the push plate 12 and the clamping block 11. The setting of the push plate 12 facilitates the effect of controlling the movement of the clamping block 11.

[0021] Example 2

[0022] like Figure 1-4As shown, a rubber pad 10 is fixedly connected at the middle position of the clamping plate 9. The setting of the rubber pad 10 increases the friction between the clamping plate 9 and the workpiece, thereby improving the stability of the workpiece when being clamped. The surface of the push plate 12 and the surface of the square groove are both fixedly connected with a spring 13. The setting of the spring 13 allows the push plate 12 to automatically return to its original position after moving, thereby reducing the manual operation steps and simplifying the operation process. A track column 14 is fixedly connected to the surface of the square groove, and the track column 14 is inserted in the spring 13 and connected to the push plate 12. The track column 14 limits the activity of the spring 13, thereby avoiding irregular contraction or extension of the spring 13 and improving its use. Life, both ends of the movable plate 6 are fixedly connected with a fixed shaft 15, and the hollow sleeve plate 7 is rotatably connected with the fixed shaft 15. When the clamping plate 9 is not needed, the hollow sleeve plate 7, the movable plate 8 and the clamping plate 9 can be rotated and moved to the two sides of the mounting plate 2 through the setting of the fixed shaft 15, so as to avoid the clamping plate 9 blocking the grinding disc on the hand-cranked grinder when processing smaller workpieces, thereby affecting the processing. One end of the fixed shaft 15 is fixedly connected with a docking block 16, and the docking block 16 and the hollow sleeve plate 7 are threadedly connected with a No. 2 bolt 17. With the help of the docking block 16 and the No. 2 bolt 17, the hollow sleeve plate 7 can be fixed after the activity.

[0023] Working principle:

[0024] like Figure 1-4 As shown, when the utility model needs to clamp the fixing plate 9 to assist in clamping and fixing the workpiece, first remove the No. 2 bolt 17 on the docking block 16, and let the hollow sleeve plate 7 rotate upward ninety degrees on the fixed shaft 15, and then reinstall the No. 2 bolt 17 to fix the movable hollow sleeve plate 7, and then place the workpiece to be processed on the electromagnet workbench 1, and then manually rotate the torsion disk 5 to rotate the screw rod 4, drive the movable plate 6 and the hollow sleeve plate 7 to move in a straight line, so that the two clamping fixing plates 9 move toward the center of the electromagnet workbench 1, and finally the rubber pad 10 contacts the workpiece, so that the workpiece is stably clamped and fixed, which is convenient for subsequent processing.

[0025] When a higher workpiece needs to be clamped, the height of the clamping plate 9 can be changed to improve the clamping stability. When adjusting the height of the clamping plate 9, you can first hook the push plate 12 with your fingers and squeeze it to move it along the track column 14. During this period, the spring 13 is stretched, and the movement of the push plate 12 controls the movement of the card block 11, releasing the connection between the card block 11 and the hollow sleeve plate 7 and the movable plate 8. Then, the push plate 12 is pulled to drive the movable plate 8 and the clamping plate 9 to move upward. When the clamping plate 9 moves to the appropriate position, the squeezing force on the push plate 12 is slowly removed. With the help of the rebound of the spring 13, the auxiliary push plate 12 automatically returns to its position, so that the card block 11 is re-engaged with the movable plate 8 to fix the movable plate 8, and the position adjustment of the clamping plate 9 is completed.
