Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Referring to fig. 1-7, in an embodiment of the present invention, a tooling for machining a sleeve of a control valve includes: a base 1 and a sleeve 13; the three pressing blocks 2 are all arranged above the base 1, and the three pressing blocks 2 are distributed in an annular array; the three arc-shaped blocks 3 are respectively and fixedly arranged on the corresponding pressing blocks 2, and the three arc-shaped blocks 3 are all contacted with the inner ring of the sleeve 13; the three sliding chutes 4 are respectively arranged on the corresponding pressing blocks 2; the three mounting grooves 5 are all formed in the top of the base 1; the three fixing rods 6 are respectively and fixedly arranged in the corresponding mounting grooves 5; the three sliding blocks 7 are respectively sleeved on the corresponding fixing rods 6 in a sliding manner; the tensioning structure is arranged on the base 1 and used for controlling the tensioning degrees of the three arc-shaped blocks 3 and the inner ring of the sleeve 13.

The top of base 1 is seted up funnel shape groove 9, the bottom in funnel shape groove 9 is seted up thread groove 8.

The tensioning structure comprises a screw rod 10, a funnel-shaped block 11 and a hexagonal head 12, wherein the screw rod 10 is fixedly installed at one end of the funnel-shaped block 11 with a small section, the hexagonal head 12 is fixedly installed at the other end of the funnel-shaped block 11, the screw rod 10 is matched with the thread groove 8, and the funnel-shaped block 12 is matched with the funnel-shaped groove 9.

The chute 4 is a structure in which the section of one end is gradually reduced to the section of the other end.

The sliding block 7 is provided with a sliding hole, and the fixing rod 6 penetrates through the sliding hole and is in sliding connection with the sliding hole.

The utility model provides a working principle of regulating valve sleeve processing frock as follows:

when needs carry out the fluting to the sleeve inner circle, with the muffjoint on three arc piece 3, use extension hexagonal muffjoint on hexagonal head 12, install lead screw 10 screw thread in thread groove 8, it makes hexagonal head 12 rotate to rotate extension hexagonal muffjoint, thereby make lead screw 10 rotate, lead screw 10 rotates the bottom that can lower thread groove 8 and removes, thereby drive spout 4 contact and oppression briquetting 2 on funnel-shaped piece 11 and the three briquetting 2, make briquetting 2 remove, briquetting 2 removes and drives slider 7 and slide on dead lever 6, can drive arc piece 3 when briquetting 2 removes and remove, it is inseparabler to make arc piece 3 can contact with sheathed tube inner circle, thereby fix the sleeve pipe.

this device makes three arc piece can be tightly through the tight structure that rises and sleeve inner wall contact, makes the sleeve fixed, because the radian looks adaptation of arc piece and sleeve inner wall for telescopic atress is more even, can not cause the damage to the sleeve.
