Face is four planes compositions, and the adjacent two plane included angles outer corner angle angle corresponding with workpiece is identical.
This fixture makes workpiece be stablized by arranging the clamping of four planes in the face of four faces of square cross simultaneously clamp on
Be fixed on fixture the processing being easy to follow-up lathe to workpiece, but in the program, the two of workpiece corner angle are clamped by fixture
Fixing, the corner angle being locked are in stress, may result in the rib making the held position of square cross in the course of processing
Corner wear or damage, thus cause the generation of defective workpiece.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of square workpiece fixture, this fixture
Abrasion or the damage of square cross corner angle it is avoided that in the piece-holder course of processing.
Above-mentioned technical purpose of the present utility model has the technical scheme that
A kind of square workpiece fixture, including columned clamping fixture seat and fastening bolt, described clamping fixture seat is provided with along end face
Cavity and fixing workpiece with square groove, the adjacent groove face of groove two along vertical groove face be provided through clamping fixture seat and with fastening spiral shell
The internal thread hole that on bolt, screw thread coincide, fastening bolt is arranged on internal thread hole and in fastening bolt, the length of screw thread is more than interior spiral shell
The degree of depth of pit, another two adjacent groove faces are connected with the cavity face of cavity and the intersection point of two adjacent groove face extended lines is in cavity.
Use said structure, only square cross to be processed need to be put into fixture groove, and make square cross one corner angle fall
Enter in cavity, then screw two fastening bolts respectively, make fastening bolt end face be connected to respectively on adjacent two faces of square cross, make
Two groove faces of two other adjacent surface of square cross and groove compress, and finally make square cross be in clamped condition in fixture,
Be then carried out the processing to workpiece, four corner angle of such square cross the most not with holder contacts, it is to avoid rib in the course of processing
The stress at angle, the situation appearance being worn from the corner angle that can avoid workpiece or damaging.
It is further arranged to: the groove face of described groove is inlaid with one layer of hard alloy.
Use said structure, it is ensured that fixture carries out, in high-volume workpiece process, reducing the mill of fixture groove groove face
Damage, extend the service life of fixture.
It is further arranged to: on the adjacent groove face of groove two that the described cavity face with cavity is connected, be provided with anti-slip veins.
Use said structure, when, after locking square cross, anti-slip veins can increase the friction of square cross and holder contacts face
Power, it is to avoid occur micro-displacement to affect machining accuracy in the square cross course of processing in fixture groove.
It is further arranged to: described groove its excess-three angle in addition to a jiao be connected with cavity is disposed as chamfering.
Using said structure, the setting of chamfering is effectively reduced subjected to stress during fixture uses, and strengthens fixture
Intensity, thus strengthen its machining accuracy and service life.
It is further arranged to: bottom described clamping fixture seat, be provided with the screwed hole of stationary fixture.
Use said structure, conveniently this fixture is fixed on machining tool.
It is further arranged to: described clamping fixture seat and fastening bolt are made by No. 45 Steel materials.
Using said structure, No. 45 steel have preferable mechanical performance, have higher cost performance simultaneously, use this material
Guarantee in the case of can ensureing cost that fixture has preferable gripping performance machining accuracy.
It is further arranged to: described cavity cross section is circular or rectangle or regular hexagon.
In sum, this utility model has the advantages that
1. on the premise of can ensureing to clamp square cross, effectively protect four corner angle of workpiece in the course of processing the most frayed
And damage.
2. the setting of anti-slip veins can ensure that the minute movement of workpiece process, improves Workpiece Machining Accuracy.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment 1: a kind of square workpiece fixture, as depicted in figs. 1 and 2: include the cylinder made by No. 45 Steel materials
The clamping fixture seat 1 of shape and fastening bolt 2, clamping fixture seat 1 is provided with square groove 4 along end face, and groove 4 groove face surface inserting has one layer
Boride based cemented carbide, groove 4 has three adjacent chamferings 7, and two groove faces between three adjacent chamferings 7 are each vertically
Groove face is provided with an internal thread hole 5 mated with fastening bolt 2, fastening bolt 2 moving rotary in internal thread hole 5, female thread
Clamping fixture seat 1 side is run through in hole 5, and in fastening bolt 2, reach is more than the degree of depth of internal thread hole 5.
Two other adjacent groove face surface configuration of groove 4 has anti-slip veins 6, and the point of intersection of this two adjacent groove face extended line is arranged
The cavity 3 and the intersection point that have cross section to be circle are in cavity 3.
The screwed hole 8 of stationary fixture it is provided with bottom clamping fixture seat 1.
Operation principle: square cross to be processed is put into fixture groove 4, and makes square cross one corner angle be in cavity 3
In, screw two fastening bolts 2, make fastening bolt 2 one end respectively abut with square cross one side, such fastening bolt 2 side of being connected to
On adjacent two faces of shape workpiece, the anti-slip veins 6 of 4 two groove faces of two other adjacent surface of square cross and groove is made to compress,
Make square cross be in clamped state in fixture eventually, then secure fixtures on lathe and then the other side by screwed hole 8
Shape workpiece is processed.Thus by while two faces of clamping square workpiece, strengthen the stability to piece-holder, lead to simultaneously
The setting in hole 3 avoids the groove face of the corner angle between two faces that square cross contacts simultaneously and the groove 4 of fixture with anti-slip veins 6
Contact, and in the course of processing, the other three corner angle of square cross also with holder contacts, thus will not avoid in the course of processing
The stress of corner angle, the situation appearance being worn from the corner angle that can avoid workpiece or damaging.
