Embodiment 1

[0045] This embodiment provides a tooling for processing the middle mouth of the valve body. Figure 1 to Figure 4 As shown, it includes a base 200, a positioning part 300, a driving part 400 and a clamping part 420; wherein, the positioning part 300 is arranged on the base 200, a gap is provided between the positioning part 300 and the base 200, and the positioning part 300 is provided with a first positioning part on the side away from the base 200; the driving part 400 is arranged between the base 200 and the positioning part 300, and the driving part 400 is provided with two connecting blocks 410, and the two connecting blocks 410 respectively pass through Over the positioning part 300, and the driving part 400 has a degree of freedom of movement close to or away from the positioning part 300; there are two clamping parts 420, and the two clamping parts 420 are hinged with the two connecting blocks 410 in one-to-one correspondence; the two clamping parts The clamping parts...

Embodiment 2

[0058] This embodiment relates to a tooling for processing the middle mouth of a valve body, which has roughly the same structure as the tooling provided in Embodiment 1, the difference is that, refer to Figure 5 As shown, the tooling of this embodiment also includes a screw 610 and a guide shaft 620; wherein, the screw 610 is rotatably arranged on the positioning member 300, and the screw 610 includes a left-handed section and a right-handed section connected in series; two first positioning One of the blocks 310 is provided with a left-handed threaded hole, and the other is provided with a right-handed threaded hole; the left-handed threaded hole is screwed with the left-handed section, and the right-handed threaded hole is screwed with the right-handed section; the guide shaft 620 is fixed on the positioning member 300 and parallel to the screw rod 610 ; two first positioning blocks 310 are respectively provided with guide holes 350 , and each guide hole 350 is slidably sle...

Embodiment 3

[0065] This embodiment relates to a tooling for processing the middle mouth of a valve body, which has roughly the same structure as the tooling described in Embodiment 1, the difference lies in: refer to Image 6 As shown, in this embodiment, a backing plate 700 is provided in the first arc-shaped groove 311, and the backing plate 700 is supported on the wall surface inside the first arc-shaped groove 311 via an elastic member; the backing plate 700 is used to connect with the corresponding port The inner side of the flange 110 fits together; towards the direction close to the bottom of the first arc-shaped groove 311 , the side of the backing plate 700 for fitting with the port flange 110 includes an inclined guide section 710 and a fitting section 720 in sequence.

[0066] That is to say, in the tooling of this embodiment, after the port flange 110 of the valve body 100 is inserted into the first arc-shaped groove 311, specifically, the backing plate 700 abuts against the si...

Abstract

The invention provides a tool and equipment for machining a middle opening of a valve body, relates to the technical field of valve body machining equipment, and aims at solving the technical problem that the clamping efficiency is low during existing valve body machining. The tool for machining the middle opening of the valve body comprises a base, a positioning piece, a driving piece and a clamping piece. The positioning piece is arranged on the base, a gap is formed between the positioning piece and the base, and a first positioning part is arranged on the side, away from the base, of the positioning piece. The driving part is arranged between the base and the positioning part, two connecting blocks are arranged on the driving part, the two connecting blocks penetrate through the positioning part respectively, and the driving part has the moving freedom degree of getting close to or getting away from the positioning part; the number of the clamping pieces is two, and the two clamping pieces are hinged to the two connecting blocks in a one-to-one correspondence mode. The two clamping pieces are respectively provided with a second positioning part; and when the driving piece is far away from the positioning piece, the second positioning parts on the two clamping pieces are driven to correspondingly clamp two port flanges of the valve body with the first positioning parts. The tool for machining the middle opening of the valve body has high clamping efficiency.

Description

technical field [0001] The invention relates to the technical field of valve body processing equipment, in particular to a tooling and equipment for valve body center opening processing. Background technique [0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. It is a device that makes or stops the medium in piping and equipment and controls its flow. [0003] The valve generally includes a valve body and a control member, and the valve body includes an inflow port, an outflow port, and a middle port. Among them, the operating end of the control member is located outside the valve body, and the execution end of the opening and closing member is located inside the valve body. The corresponding action constitutes the connection, shutoff or partial closure between the inlet and the outlet, etc. The processing of the middle port of the valve body is related to the sealing performance of the valve and is an important part o...
