Description
Technical field
It the utility model is related to clamp art, and in particular to a kind of barrier part clamp for machining.
Background technology
Tube kind part normally shape precision and position accuracy demand are higher, and the relatively thin sleeve part of hole wall is being processed
It is middle because by clamping force, cutting force, cutting heat etc. act on after be deformed, it is necessary to ensure major surfaces positional precision while
Also to prevent from deforming, when in the prior art clamping barrier part by chuck etc., usually because clamping force produces barrier part surface
Changed shape, and workpiece is removed from fixture after completing processing, and deformation-recovery causes to process unqualified.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of barrier part clamp for machining, clamping deformation
Small, crudy is high.
The purpose of this utility model is achieved through the following technical solutions：
A kind of barrier part clamp for machining, it includes base, and the base center is provided with the mandrel of annular, and base is provided with least
Two cylinders, the piston rod of one end of the close mandrel of the cylinder are provided with vee-block, and the mandrel is along the circumferential direction uniformly opened
Provided with least nine through holes, support nail is provided with the through hole, base center is further opened with screwed hole, is provided with the screwed hole
Adjusting screw, the top of the adjusting screw are located in mandrel, and adjusting screw is provided with circular cone.
The top surface diameter of described circular cone is more than the basal diameter of circular cone, and the internal diameter of the mandrel is more than circular cone
Top surface diameter.
The end thereof contacts circular cone of described support nail, the other end of support nail are provided with pad.
Described circular cone and adjusting screw is integrally formed.
Described circular cone is provided with knob.
The beneficial effects of the utility model are：Part is clamped using vee-block, by mandrel and support nail to barrier part
Internal support and positioning are carried out, the contact area of fixture and workpiece is reduced, reduces deformation, improve crudy；Using
Cylinder drives vee-block, clamps quick.

Embodiment
The technical solution of the utility model, but guarantor of the present utility model are described in further detail with reference to specific embodiment
Shield scope is not limited to as described below.
As shown in Figure 1, 2, a kind of barrier part clamp for machining, it includes base 1, and the center of base 1 is provided with the mandrel 2 of annular, bottom
Seat 1 is provided with least two cylinders 3, and the piston rod of one end of the close mandrel 2 of cylinder 3 is provided with vee-block 4, and mandrel 2 is circumferentially
Direction uniformly offers at least nine through holes, is provided with support nail 5 in through hole, the center of base 1 is further opened with screwed hole 6, screwed hole 6
Interior to be provided with adjusting screw 7, the top of adjusting screw 7 is located in mandrel 2, and adjusting screw 7 is provided with and adjusting screw 7 is integrally formed
Circular cone 8, the end thereof contacts circular cone 8 of support nail 5, the other end of support nail 5 is provided with pad；The top surface diameter of circular cone 8
More than the basal diameter of circular cone 8, the internal diameter of mandrel 2 is more than the top surface diameter of circular cone 8.It also includes knob 9, and knob 9 is set
Above circular cone 8.
During processing, workpiece is sheathed on outside mandrel 2, adjusting knob 9 moves down adjusting screw 7, and circular cone 8 is to moving down
Dynamic, circular cone 8 moves down, gradually increases positioned at the diameter of the circular cone 8 of the place plane of support nail 5, due to the surface of circular cone 8
Contacted with support nail 5, thus support nail 5 by the thrust of circular cone 8 so as to laterally move, the pad on support nail 5
Contacted with workpiece inner wall, complete the centering to workpiece and inner support.
Moved finally by the piston rod of drive cylinder 3, vee-block 4 moves, until clamping workpiece, you can completion pair
The clamping of workpiece.
Described above is only preferred embodiment of the present utility model, it should be understood that the utility model is not limited to herein
Disclosed form, the exclusion to other embodiment is not to be taken as, and can be used for various other combinations, modification and environment, and
It can be modified in contemplated scope described herein by the technology or knowledge of above-mentioned teaching or association area.And this area
The change and change that personnel are carried out do not depart from spirit and scope of the present utility model, then all should be in right appended by the utility model
It is required that protection domain in.
