Key；
The disk peripheral surface that connects is equipped with step structure；
Described pull rod one end penetrates described connect after disk and the head that tenses is fixedly connected, the pull rod and the tension capitiform
Into fixed structure connect disk through described, the pull rod other end is tenses adjustable side.
Preferably, the pull rod and the tension head are set by thread fitting, the pull rod and the tension head connecting pin
There is locking nut.
Preferably, the tension adjustable side of the pull rod is helicitic texture, is cased with adjusting on the tension adjustable side of the pull rod
Nut.
Preferably, also it is cased with backing plate on the tension adjustable side of the pull rod.
Preferably, disk and the crosshead body contact jaw of connecing is equipped with lug boss, the lug boss and the crosshead body z's
Groove part matches.
As described above, a kind of compressor crosshead body special fixture of the utility model, has the advantages that：
First, it can realize the clamping to crosshead body, center lathe is allowed to be processed crosshead body；
2nd, using the cooperation for tensing head and lateral pin, clamping crosshead body and the action for removing crosshead body are simple and fast；
3rd, it connects disk directly with lathe spindle to couple and pull rod is used to pass through machine tool chief axis, ensures the concentricity in rotation,
And degrees of tensions is adjustable, ensure that the precision of processing and the efficiency of clamping workpiece.
4th, by the setting of the lug boss of butt plate, the positioning to crosshead body, multiple stress point cooperations, folder are realized
It is more preferable to hold fixed effect.

Specific embodiment
Illustrate the embodiment of the utility model by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily.
It please refers to Fig.1, it should however be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., only coordinating
The revealed content of specification, so that those skilled in the art understands and reads, being not limited to the utility model can be real
The qualifications applied, therefore do not have technical essential meaning, the tune of the modification of any structure, the change of proportionate relationship or size
It is whole, in the case where not influencing the effect of the utility model can be generated and the purpose that can reach, should all still fall in the utility model institute
The technology contents of announcement are obtained in the range of covering.Meanwhile in this specification it is cited as " on ", " under ", "left", "right",
The term of " centre " and " one " etc. is merely convenient to understanding rather than to limit the enforceable range of the utility model for narration,
Its relativeness is altered or modified, in the case where changing technology contents without essence, when being also considered as the enforceable scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of compressor crosshead body special fixture, including lateral pin 1, tense head 2,
Connect disk 3 and pull rod 4；1 activity of lateral pin passes through the tension head 2, and the lateral pin 1 and the tension head 2 are vertical；The tension
First 2 activity is connect described in penetrating in disk 3, and flat key 21 is equipped at the tension head 2 and the shaft hole matching for connecing disk 3；It is described to connect disk 3
Peripheral surface is equipped with step structure 31, and disk 3 and the crosshead body z contact jaws of connecing is equipped with lug boss 32, the lug boss 32 and institute
State the groove part matching of crosshead body z.Described 4 one end of pull rod penetrate it is described connect after disk 3 and the head 2 that tenses is fixedly connected,
