Detailed ways

The preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

Example 1

As shown in Figure 1-3, a fixing device for grinding alloy bushings, including a positioning box 1, a cylinder 2 and a movable clamping piece 3, the lower side of the positioning box 1 is fixed with a fixing frame 4, and the fixing frame 4 The middle part of the screw is fixed with the cylinder 2, the side screw of the positioning box 1 is fixed with the control panel 5, the positioning box 1 is provided with the driving chuck 6, and the upper side of the driving chuck 6 is provided with four wheel grooves 7, and the wheel groove 7 There is a rotating roller 8 inside, and the piston rod of the cylinder 2 passes through the positioning box 1 and is fixedly connected with the driving chuck 6. The upper side of the positioning box 1 is provided with four limit chutes 9, and the limit chute 9 is equipped with Movable clamping part 3, movable clamping part 3 all comprises driving plate 11 and moving clamping plate 10, and one side of moving clamping plate 10 is provided with arc-shaped surface 12, and one side of driving plate 11 is provided with inclined surface 13, and the side of moving clamping plate 10 is provided with A No. 1 slider 14 is fixedly connected to the lower side, a No. 2 slider 16 is fixedly connected to the upper side of the drive plate 11 , and a connecting block 15 is fixedly connected between the No. 1 slider 14 and the No. 2 slider 16 .
