Technical field

It is specifically to be related to a kind of thin-wall steel tube clamping the utility model relates to a kind of valve body assembly tooling of pilot valve Device.

Background technique

Pilot valve is the auxiliary valve used to manipulate the control mechanism in other valves or element.The valve of conventional pilot valve Body is mainly made of thin-wall steel tube, and pilot valve again welds capillary and valve body after needing to be fixed valve body with fixture in assembly It is fixed, thus fixture is as a kind of important tool for being applied to pilot valve assembly, assembly efficiency of the degree of optimization to pilot valve Play the role of key.But the assembly of existing pilot valve is predominantly artificial, corresponding fixture operation and the mode of action also compared with It is single.The unicity of fixture is mainly reflected in following two points: qualified often firstly, for certain function of valve body Only a kind of assembling jig of model, i.e., a kind of model valve body can only use a kind of fixture；Secondly, it is impossible to be used in automatic assembling.

Utility model content

The purpose of this utility model is: providing a kind of thin-wall steel tube clamping device, which can be to the dress of some complexity It optimizes with mode with the working method of power is needed, so as to improve the Automated assembly degree of pilot valve, is mentioned to reach The effect of high assembly work efficiency.

The technical solution of the utility model is: a kind of thin-wall steel tube clamping device, including pedestal, fixed installation are on the base The clamp system and relieving mechanism that the mandrel and installation that Fang Qianhou extends are matched with mandrel on the base；The clamp system Including two mounting bases set up separately along mandrel axis bilateral symmetry, two linking arms being rotatably installed in corresponding mounting base and fixed peace Mounted in two pressing plates being correspondingly connected on arm, the pivot center of the linking arm and the plate face of pressing plate are parallel with the axis of mandrel, The torsional spring that mandrel surface is pressed on dynamic pressure plate is separately installed between two linking arms and corresponding mounting base；The relieving mechanism Including the mandril being installed vertically on immediately below mandrel, the mandril guiding be slidably mounted in pedestal, the top of mandril be fixed with The jacking block of the synchronous press cooperation of two linking arm, front and back guiding is slidably fitted with through inclined-plane cooperation and the top in pedestal The push rod of bar transmission connection.

Rubber sheet gasket is fixed on the surface of the pressing plate.

The push rod guiding is slidably mounted in the corresponding guide chute opened up in pedestal rear portion, front end and base in push rod The spring for driving putting back-end to stretch out pedestal is top-loaded between seat.

The utility model is designed using symmetrical structure, is matched by push rod with torsional spring and mandril is driven to move up and down, real The synchronous of existing two pressing plates compresses or release, have compact-sized, operation rationally, assembly technology is simple, clamping is reliable, design is skilful Wonderful, the characteristics of assembly efficiency is high, the operation is stable, it can satisfy the requirement of automatic assembly line.
