Embodiment Construction

[0008] The embodiment is shown in the figure: a clamping device, the clamping device includes a tension screw 1 and a shaft sleeve 2, the end of the shaft sleeve 2 is also provided with a plurality of clips 3, and the shaft sleeve 2 sets On the outside of the tension screw 1 , the end of the tension screw 1 is in an inverted cone shape, and the plurality of clips 3 wrap the end of the tension screw 1 . When the tightening screw 1 is tightened, the plurality of clips 3 can expand outward, and then press the inner diameter of the working clip 5 to fix the working clip 5 . One end of the tightening screw 1 without an inverted conical head is fixed on the rotating disk 6 of the lathe.

[0009] The part where the shaft sleeve 2 and the clip 3 are connected is also provided with an annular boss, and the outer radius of the boss is larger than the inner radius of the working clip 5 . The positioning of the working clip 5 is facilitated.

[0010] The clamping device further includes...

Abstract

The invention relates to the field of prestressing device manufacture, in particular to a clamping device. The clamping device comprises a tensioning screw and a shaft sleeve (2), wherein multiple clamp pieces (3) are further arranged at the end of the shaft sleeve (2), the shaft sleeve (2) is arranged on the outer side of the tensioning screw (1) in a sleeved mode, the end of the tensioning screw (1) is in a shape of an inverted cone, and the multiple clamp pieces (3) wrap the end of the tensioning screw (1). The clamping device is fixed through an inner hole formed in an external expansion type extrusion working clamp piece (5), is firmly fixed, does not easily loosen and is simple, efficient and accurate in positioning.

Description

technical field [0001] The invention relates to the field of prestressing equipment manufacture, in particular to a clamping device. Background technique [0002] It is more difficult to make the working clip in the prestressing equipment, because the shape of the working clip is tapered, it is difficult to fix; the labor cost is high, and the fixing is not accurate. Contents of the invention [0003] In order to solve the above technical problems, the present invention proposes a clamping device, the clamping device includes a tightening screw and a bushing, the end of the bushing is also provided with a plurality of clips, and the bushing is set on On the outer side of the tension screw, the end of the tension screw is in an inverted tapered shape, and the plurality of clips wrap the end of the tension screw. [0004] A further technical solution of the present invention is: the connection between the shaft sleeve and the clip is further provided with an annular boss, a...
