[0016] Figure 1 It is a structural schematic diagram of the utility model.

[0017] As attached Figure 1 As shown, a fastening type laser centering instrument includes a measuring unit 1, a slider 2 is fixed at the bottom of the measuring unit 1, the slider 2 is inserted in a slide groove of a base 3, and a clamping mechanism 4 for fixing the slider 2 in the slide groove is installed on the left and right sides of the base 3. A frame 5 is fixedly connected to the bottom of the base 3, and a plurality of splints 6 are evenly distributed on the frame 5. The splints 6 are slidably connected to the frame 5. A plurality of splint moving mechanisms 7 are installed on the frame 5, and the splint moving mechanisms 7 are connected to the splints 6.

[0018] Racks 8 are fixed on both the left and right sides of the slider 2, and the slider 2 is provided with a length scale.

[0019] The clamping mechanism 4 includes a rod body 41, an elastic member 42, and a clamping block. The rod body 41 passes through the through hole of the side wall of the base 3. The elastic member 42 is connected between the rod body 41 and the base 3. A clamping block for clamping the rack 8 is provided at the front end of the rod body 41.

[0020] The elastic member 42 is a spring.

[0021] The clamp plate moving mechanism 7 includes a screw rod 71 and a nut 72 . The screw rod 71 passes through a through hole on the frame 5 . The nut 72 is fixed on the frame 5 . The nut 72 is threadedly connected to the screw rod 71 . The front end of the screw rod 71 is movably connected to the back of the clamp plate 6 .

[0022] A guide rod 73 is provided on the back of the clamping plate 6 , and the guide rod 73 passes through a guide hole on the frame 5 .

[0023] The clamping plate 6 is an arc-shaped plate.

[0024] The splint 6 is wrapped with a silica gel layer.

[0025] The working method of the present application is as follows: first, the axis of the device is passed through the frame 5, and the axis is placed between the three clamps 6. Then, the screw rod 71 is turned, and the screw rod 71 moves forward along the nut 72, thereby pushing the three clamps 6 toward the axis until the axis is clamped and fixed. Then, the slider 2 at the bottom of the measuring unit 1 is placed into the slide groove of the base 3, and the racks 8 on the left and right sides are matched in the linear grooves on the inner wall of the slide groove.
