Description
Technical field
This utility model is related to frock clamp manufacturing technology field, and especially one kind is used for part general assembly centering or jackshaft
Hold the aid of adjustment etc..
Background technology
Jackscrew frock needs good stability and is easy to as the aid of part general assembly centering or intermediate bearing adjustment etc.
Adjust and use.There is a kind of jackscrew frock, this jackscrew frock includes the pedestal made with angle bar and the regulation spiral shell being located on this pedestal
Bolt.There is holding of support during the centering debugging for ship unit general assembly or intermediate bearing adjustment etc. in this jackscrew frock
Stress and the problem of stability difference.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of jackscrew frock, to solve to be made with existing jackscrew frock
Carry out holding capacity in the debugging process of part and the problem of stability difference for aid.
The technical scheme that this utility model solution technical problem is adopted is: this jackscrew frock includes pedestal and is located at this
Regulating bolt on pedestal, described pedestal has revolution body and the screwed hole being located on described revolution body axial line, in institute
State screw thread in the hole and be coated with described regulating bolt, the bolt head of described regulating bolt stretches out the top surface of described revolution body, described
The top of bolt head is ball-crown body.
In above-mentioned jackscrew frock technical scheme, more specifically technical scheme it may also is that described revolution body be upper little under
Big cone, a diameter of 46 millimeters -54 millimeters of described facies basialis pyramidis.
Further: at least 8.8 grades of the performance rate of described regulating bolt.
Due to employing technique scheme, this utility model compared with prior art has the advantages that 1, by
In pedestal have revolution body it is ensured that pedestal steady, and bolt head adopt ball-crown body design, make support feature contacts face
Good stability；2nd, jackscrew tool structure is simple, makes simple, has not only saved material, accurate using the regulation of jackscrew frock
Property, centering good, data is difficult to change, and greatly reduces the workload of check centering.
Brief description
Fig. 1 is the structural representation of this utility model embodiment.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
