Specific embodiment
Below in conjunction with the drawings and specific embodiments to the utility model proposes thin-walled circular cone threeway accessory turning clamping dress
It sets and is described in further detail.It should be noted that attached drawing is all made of very simplified form and using non-accurate ratio, only
Purpose to convenient, apparent aid illustration the utility model embodiment.
Thin-walled circular cone threeway accessory turning clamping device described in the utility model tooling ontology as shown in Figure 2, Fig. 3 institute
The composition such as positioning thread insert, adjustment swivel nut shown in Fig. 4 and tie down screw, studdle and nut for showing.Thin-walled shown in FIG. 1
Circular cone threeway part has the flange 11 being arranged symmetrically at two.Tooling ontology shown in Fig. 2 is by upper plectane 21, middle annulus 22 and bottom circle
Plate 23 is formed by welding, circumferential to be evenly distributed with two location holes 24 and four supported holes 25 on middle annulus 22, is respectively intended to cooperate with installation
Two positioning thread inserts and four studdles are equipped with clamping end 26 on the plectane of bottom,.Positioning thread insert shown in Fig. 3 can be with tooling
The location hole 24 of ontology realizes small―gap suture cooperation positioning, and one end is equipped with internal screw thread 31.The abutting end of adjustment swivel nut shown in Fig. 4
