Embodiment 1

[0028] Such as figure 1 Shown is the valve body 1 to be processed, the valve body 1 has a cylindrical end 1a at the front end, an outlet flange 1b at the rear end, an interface square platform 1c on the top, and an inlet flange 1d on the right, as shown in Figures 2 to 4 As shown, this embodiment provides a turning fixture for a valve body 1, including a disc 2, a rear support 3, a mandrel 4, an opening pad 5, a spring pad 6, a shoulder nut 7, a support cylinder 8, a round nut 9, Left support 10, right support 11, left trapezoidal nut 12, right trapezoidal nut 13, large screw plug 14, left arc block 15, left top block 16, small screw plug 17, right arc block 18, right top block 19;

[0029] Disc 2 is a stepped hollow columnar structure. The end surface of the small cylinder is provided with a concave stop and 3 groups of 6 connection holes according to the interface of the lathe faceplate. The end surface of the large cylinder is provided with a support mounting hole. The hol...

Embodiment 2

[0035]After the inlet flange 1d of the valve body 1 is processed, the processing of the interface platform 1c is continued. In this embodiment, the end of the large screw plug 14 abuts against the right inlet flange 1d of the valve body 1 through the left top block 16. The end of the small screw plug 17 is pressed against the outside of the left end of the valve body 1 through the right arc block 18; at the same time, an open backing plate 21 and a counterweight 20 are added, and the open backing plate 21 is arranged on the rear support 3 and the valve body 1. Between the outlet flanges 1b, an open backing plate 21 opens radially outwards from the center hole, and a circular counterbore groove is set in the middle, and the open backing plate 21 is set on the outside of the support cylinder 8 through the counterbore groove ; The counterweight 20 is arranged outside the left trapezoidal nut 12; ; After the processing of embodiment 1 is completed, unscrew the shoulder nut 7 on the...

Abstract

The invention provides a valve body turning clamp. A cylindrical end is arranged at the front end of a valve body to be machined, an outlet flange is arranged at the rear end of the valve body, an interface square table is arranged at the top of the valve body, and an inlet flange is arranged on the right portion of the valve body. The valve body turning clamp comprises a disc, a rear support, a mandrel, an elastic pad, a shouldered nut, a left support, a right support, a left trapezoidal nut, a right trapezoidal nut, a large screw plug, a left ejector block, a left arc block, a small screw plug, a right ejector block and a right arc block. The valve body turning clamp is easy and convenient to operate, stable and reliable in function and capable of meeting the requirement for batch production of products.

Description

technical field [0001] The invention belongs to the technical field of clamping devices, and in particular relates to a turning clamp for a valve body. Background technique [0002] Due to the functional requirements of special valves, the valve body usually has an asymmetric structure and a relatively complicated shape. It is generally formed by casting and then processed by numerical control equipment. The valve body of a newly developed valve has an asymmetrical four-way structure, which is mainly composed of an outlet flange, a cylindrical end, an inlet flange, an interface square platform, a partial cylindrical surface on the side, and an inner cavity. The design requires forging processing, and The roughness requirements of the sealing grooves at each outlet are very high. According to the process analysis of the structural characteristics and processing requirements of the valve body, it is determined that the basic shape and inner cavity structure of the parts are p...
