Example Embodiment

[0030] As the second embodiment of the present invention, the screw 7 can be pressed down in a rotating manner first, and after pressing down, the adapter wheel 8 and the control frame 6 are connected as a whole. When the input handle 8c is rotated again, at this time The entire adapter wheel 8 and the control frame 6 rotate around the center of the control frame 6 synchronously, and can also achieve the function of clamping or loosening the valve body. Among them, the horizontal sliding distance of the two pressing plates 3 is twice the distance from the hinge point of the left end of the long link 5 and the adapter wheel 8 to the center of the control frame 6.

[0031] It can be concluded from the above two embodiments that the present invention can effectively control the horizontal sliding distance of the two pressing plates 3, and can be adapted to clamp valve bodies of different sizes and models, and has a wide range of applications.

Abstract

The invention relates to a universal valve body machining fixture. The universal valve body machining fixture comprises a workbench and locating pins, sliding grooves are distributed all around the workbench, and pressing plates and hinged seats are installed in the sliding grooves in a sliding mode; a plane four-bar mechanism is connected between the pressing plates and the hinged seats, a long connecting bar is hinged to the lower end of the left-most pressing plate, the left portion of the long connecting bar is provided with a control rack, the front end of the control rack is provided with a circular groove, a screw is installed in the circular groove in a threaded mode, and an adapting wheel is rotatably installed in the circular groove and hinged to the long connecting rod at any peripheral edge end; an annular groove is formed in the center position of the adapting wheel, the circular arc end of the adapting wheel is provided with a clamping groove, an annular insertion block is fixedly installed on the screw, the front end of the circular groove is communicated with a square groove, an insertion pin is installed in the square groove in a sliding mode, and the center position of the control rack is connected with a supporting rack. According to the universal valve body machining fixture, by means of the connecting mode of the adapting wheel and the control rack, horizontal sliding distance of two pressing plates can be controlled, the effect of clamping valve bodies with different sizes and types can be achieved, and the application range is wide.

Description

technical field [0001] The invention relates to a clamp, in particular to a universal processing clamp for a valve body. Background technique [0002] Fixture refers to the device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to accept construction or inspection. Generally speaking, when most fixtures are clamped, the size and type of workpieces that can be clamped by their own clamping devices are often limited, so that the range of applicable workpieces that can be clamped by a single fixture is often very rare. This kind of situation is particularly prominent in the processing of valve bodies and valves. This often brings huge cost consumption to valve manufacturing. Contents of the invention [0003] Aiming at the defects of narrow and single types of valve bodies clamped by clamping equipment for valve body processing fixtures, the present invention proposes a universal processing fixture for va...
