BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0013] like Figure 1 As shown, an automatic centering clamping device for special-shaped parts includes two mutually matching positioning blocks 2, two guide shafts 3, two clamping slides 4, a base 5, a clamping screw 6, a fixing pin 7 and a plurality of fixing screws 8. The base 5 is provided with two mounting holes for mounting the automatic centering clamping device on the processing equipment. Two clamping slides 4 are mounted on the base, and the clamping screw 6 matches with the two clamping slides 4; the two positioning blocks 2 are respectively fixed above the two clamping slides 4, the front of the two guide shafts are respectively matched with the two positioning blocks, and one end of each is fixed to one of the positioning blocks through the fixing pin 7; the plurality of fixing screws 8 are used for connecting related parts according to the figure. Adjust the clamping screw 6 to clamp the two clamping slides.

[0014] A stepped groove is provided on the top of the base 5 , and stepped slide grooves are provided at both ends of the clamping slider 4 , and the stepped slide grooves at both ends are correspondingly installed at the two stepped side wall positions of the stepped groove.

[0015] The clamping screw 6 is a screw clamping mechanism.

[0016] The working process is as follows: first, the base 5 of the automatic centering clamping device for special-shaped parts is provided with two holes for installing the automatic centering clamping device on the processing equipment. Then, the workpiece 1 to be processed is placed between the two positioning blocks, and the positioning blocks are driven to clamp the workpiece 1 to be processed by rotating the clamping screw 6 and moving the two clamping slide blocks 4, thereby realizing the automatic centering function of the special-shaped parts.
