The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 3, the valve body 1 includes a body 11, and a first boss 12 and a cylindrical second boss 13 disposed on two opposite sides of the body 11, and a through groove 14 is disposed in the center of the valve body 1 and concentrically penetrates through the first boss 12, the body 11, and the second boss 13. The outer circle end face of the first boss 12 and the inner hole of the through groove 14 need to be lathed on a horizontal lathe.

As shown in fig. 2 to fig. 3, the present embodiment provides a clamp for processing an inner hole and an outer circular end surface of a valve body, including: the device comprises a mounting seat 2, three clamping seats 3, three clamping oil cylinders, two supporting seats 4 and an adjusting seat 5.

Wherein, three press from both sides tight seat 3 and all install on mount pad 2 along the orientation with keeping away from the direction mobilizable in mount pad 2 center, three press from both sides tight hydro-cylinder drive connection three press from both sides tight seat 3 respectively. The three clamping seats 3 are used for clamping the second boss 13, are uniformly distributed on the periphery of the second boss 13, and each clamping seat 3 is provided with a clamping block 31 for abutting against and clamping the second boss 13. Three tight seat 3 of clamp of three tight hydro-cylinder drive moves towards and keeps away from mount pad 2 central authorities, presss from both sides tight second boss 13 back as three tight oil of clamp, leads to groove 14 and mount pad 2 central authorities centering, is convenient for follow-up car processing first boss 12's excircle terminal surface and leads to groove 14 hole.

Moreover, two clamping blocks 31 are arranged on each clamping seat 3, and six clamping blocks 31 of the three clamping seats 3 are uniformly distributed and pressed and clamped on the end surface of the outer circle of the second boss 13; and be equipped with a plurality of toper archs 32 on pressing from both sides tight piece 31, can high-efficient convenient tight second boss 13 of clamp, then reach the effect of clamping valve body 1, safety and stability. Meanwhile, the clamping seat 3 is provided with a limiting block 33 for limiting the placement of the valve body 1, the limiting block 33 is distributed around the body 11, the limiting block 33 is matched with the corresponding periphery of the body 11, the placement position and the angle of the valve body 1 can be further limited and positioned, and the pertinence is achieved. In the actual production demand, can be with pressing from both sides tight piece 31 movable mounting on supporting seat 4, press from both sides tight piece 31 and have certain rotation space and angle, the tight second boss 13 of clamp that can better more adapt.

As shown in fig. 2 to 3, two supporting seats 4 and two adjusting seats 5 are mounted on the mounting seat 2 and spaced from the three clamping seats 3. Two supporting seats 4 are fixed on the mounting seat 2, and supporting blocks 41 used for limiting the abutting body 11 are arranged on the two supporting seats 4. The adjusting seat 5 is rotatably mounted on the mounting seat 2, and two adjusting blocks 51 for limiting and abutting against the body 11 are arranged on the adjusting seat 5. After the valve body 1 is placed on the mounting seat 2, the two supporting blocks 41 are supported on the end surface of the body 11 facing the second boss 13, and at this time, the adjusting seat 5 rotates to a proper angle, so that the two adjusting blocks 51 can be supported and abutted on the end surface of the body 11 facing the second boss 13, and the suspension condition of one of the adjusting blocks 51 cannot occur. The body 11 of the valve body 1 has four corners, and the two supports and the two adjusting blocks 51 support and abut against the four corners of the body 11 respectively, so that the clamping position of the valve body 1 is better and more stably supported and limited. Then drive three and press from both sides tight hydro-cylinder, three press from both sides tight seat 3 and move until pressing from both sides it tightly towards second boss 13, the simple operation, the tight valve body 1 of clamp that can rapid and stable is convenient for car processing.

The clamp is simple in structure, can quickly and safely clamp the valve body 1, is convenient for turning the excircle end face and the inner hole of the through groove 14, is flexible and practical, and is high-efficient and stable.
