Abstract
The invention discloses a kind of bicylindrical positioning fixture, which includes support, fixed block, positioning column, protection block and bolt；Positioning column is two; the radius of positioning column is consistent with the arc radius of concaved circular cambered surface in workpiece leading flank; positioning column is vertically fixedly connected on the upper surface of support; fixed block is fixedly connected on support; bolt hole is machined on fixed block, one end of bolt is fixedly connected after passing through bolt hole with protection block, and the other end of bolt is hexagonal structure; apply horizontal pressure force to protection block by screwing bolts, workpiece is being pressed between protection block and two positioning columns under the left and right of horizontal pressure force.The present invention realizes that arcwall face cooperates using special-shaped workpiece external surface and positioning column, and realizes that the quick-clamping of workpiece is fixed by bolt.
Description
Technical field
The present invention relates to a kind of positioning fixtures, and in particular to a kind of fixture positioned using workpiece own cylindrical face,
Belong to tooling and fixture technical field.
Background technique
The shape of certain workpiece be symmetrical thin wall special-shaped structure, the structure is as shown in Fig. 1, polymorphic structure it is upper
Lower surface is plane, and leading flank centre is the arc surface of protrusion, and rounding off is distinguished into the circle of indent in the two sides of arc surface
Cambered surface, trailing flank are a complete raised arc surface, and there is a centre bore to run through upper and lower surface at the center of workpiece.
Since the surface of workpiece is irregular shape, drilling processing is carried out to it and is difficult clamping and fixation, in addition, such
Workpiece can effectively improve processing quality and production efficiency in high volume to process, therefore designing reasonable fixture.
Summary of the invention
In view of this, special-shaped workpiece external surface and positioning can be utilized the present invention provides a kind of bicylindrical positioning fixture
Column realizes arcwall face cooperation, and realizes that the quick-clamping of workpiece is fixed by bolt.
A kind of bicylindrical positioning fixture, the fixture include support, fixed block, positioning column, protection block and bolt；
The positioning column is two, and the radius of positioning column is consistent with the arc radius of concaved circular cambered surface in workpiece leading flank, fixed
Position column is vertically fixedly connected on the upper surface of support, is fixedly connected with fixed block on the support, is machined with bolt hole on fixed block,
One end of bolt is fixedly connected after passing through bolt hole with protection block, and the other end of bolt is hexagonal structure, by screwing bolts to
Protection block applies horizontal pressure force, and workpiece is pressed between protection block and two positioning columns under the action of horizontal pressure force.
Further, the protection block is arcuate structure, the circle of arc radius and the raised arc surface of workpiece trailing flank
Arc radius is consistent.
Further, in order to facilitate the installation of and disassembly, be not connected between the protection block and bolt, by way of contact
Realize the compression to workpiece.
The utility model has the advantages that
1, the outer mold surface cooperation positioning column that the present invention takes full advantage of workpiece itself realizes the quick positioning to workpiece, due to
The contact surface of workpiece and positioning column is face contact, and the uniform force when being compressed can minimize the clamping change of workpiece
Shape and surface are injury-free.
2, the present invention is tightened by bolt, and clamped one time can be realized Workpiece boring, clamp structure design simply and
It is easy to operate.
Detailed description of the invention
Fig. 1 is integrally-built top view of the invention
Wherein, 1- fixed block, 2- support, 3- positioning column, 4- workpiece, 5- protection block, 6- bolt.
Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
As shown in Fig. 1, the present invention provides a kind of bicylindrical positioning fixture, which includes support 2, fixed block
1, positioning column 3, protection block 5 and bolt 6；
Positioning column 3 is two, and the radius of positioning column 3 is consistent with the arc radius of concaved circular cambered surface in 4 leading flank of workpiece, positioning
Column 3 is vertically fixedly connected on the upper surface of support 2, and fixed block 1 is fixedly connected on support 2, is machined with bolt hole on fixed block 1,
One end of bolt 6 is fixedly connected after passing through bolt hole with protection block 5, and protection block 5 is arcuate structure, arc radius and workpiece 4
The arc radius of the raised arc surface of trailing flank is consistent, and the other end of bolt 6 is hexagonal structure, by screwing bolts 6 to protection
Block 5 applies horizontal pressure force, and workpiece 4 is pressed between protection block 5 and two positioning columns 3 under the action of horizontal pressure force.
In clamping workpiece, support 2 is fixed on work top first, utilizes the interior concaved circular cambered surface of 4 leading flank of workpiece
It is carried out after quickly positioning with the cooperation of positioning column 3, turn bolt 6 moves protection block 5 towards the trailing flank of workpiece, until protection block
5 are adjacent to the trailing flank of workpiece 4, and workpiece 4 is fixed on the support, can be machined at this time to workpiece 4.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
