Description
Technical field
This utility model belongs to Machining Technology field, relates in particular to a kind of V-type positioning fixture.
Background technology
Calibration series products occupies sizable share in electro-optical equipment product, and body therein supports part and is axle system
Class part, the performance of product is played considerable influence by the precision of such part, and it is high that this kind of part has precision, the process-cycle
Long, the features such as operation difficulty is bigger, are the supporting emphasis of product.This kind of part location difficulty, each part all process steps needs
Table centering to be beaten, easily causes the inconsistent of part.Simultaneously clamp on difficulty, use conventional clamping means part yielding and not
Reliably.
The positioning precision of axle system class part and the reliability of clamping, be more scabrous problem in mechanical processing process.Axle
To movement and the rotational positioning at center there is no preferable way so far, drive method is: axial workpiece is installed on v block, V-type
Ferrum clamping parts can only limit four degree of freedom, and two degree of freedom of the rotation at axial movement and center have no idea to control.When
So can limit with block localization method and move axially, but this often positioning datum and design basis is misaligned causes under precision
Fall；The method that center rotating many employings latch plays table or line, the method inefficiency, and cause positional precision inconsistent, from
And affect the machining accuracy of part.Clamping means many employings vice of routine, the method for pressing plate class, cause part deformation, clamping
The problem of unreliable and elapsed time length, these problems had both affected the machining accuracy of part, also affect simultaneously part supporting enter
Degree, these problems can not get efficiently solving, and calibration series products axle system body just cannot ensure the most supporting.This fixture is simultaneously
Solve positioning precision, the reliability of clamping and all problems such as convenient and swift, make the precision of this part and progress all obtain
Effectively ensure.
Utility model content
The purpose of this utility model is the defect for above-mentioned prior art, it is provided that a kind of V-type positioning fixture, it is ensured that zero
Part move axially the positioning precision with center rotating, reduce block location bad and beat time of table centering；Overcome simultaneously
Clamping the part deformation and the problem of inefficiency caused, make clamping fast reliable, the course of processing is stable, and part is easy to loading and unloading,
Thus improve machining accuracy and the working (machining) efficiency of part.
To achieve these goals, the technical solution of the utility model is:
A kind of V-type positioning fixture, including the v block for the round piece to be processed that is installed, the top of described v block is arranged side by side
It is provided with movable positioning plate, abnormity pressing plate；Described v block abnormity pressing plate correspondence position be arranged with two screws, institute
Stating screw and be equipped with housing screw, described abnormity pressing plate is pressed against the top of round piece to be processed by housing screw；Described V
Sections movable positioning plate correspondence position be arranged with guide pin hole, described guide pin hole is embedded with guide finger, described work
Dynamic location-plate is pressed against the top of round piece to be processed by guide finger activity, and described round piece to be processed has alignment pin
Hole, described movable positioning plate is correspondingly arranged on fastening screw.
As the improvement to technique scheme, described abnormity pressing plate includes pressing plate body, the two ends of described pressing plate body
Offering draw-in groove, the most corresponding with the two of v block screws, the centrage of two described draw-in grooves is spatially mutually perpendicular to.As
This, it is possible to achieve easily block dress.
Compared with prior art, there is improvement acquired by this utility model and provide the benefit that:
V-type positioning fixture of the present utility model, does matrix with V shape iron, shaping-orientation pin-and-hole on V shape iron, and installation is led
To pin, movable positioning plate makes the pilot hole with guide pin hole position consistency, it is simple to slide, according to design basis in activity
Making dowel hole on location-plate and install fastening screw, round piece to be processed is placed on V shape iron, moves down activity orientation
Plate makes fastening screw insert in positioning reference holes, two degree of freedom of the rotation at the movement axial with limit and center, positioning accurate
Degree height.In clamping link, have employed abnormity pressing plate and the hold-down mechanism of housing screw cooperation, in the premise ensureing part rigidity
Under, efficiently solve the reliability of compression and the problem of agility.
This clamp structure is simple, easily manufactured, with low cost.Solve positioning precision, the reliability of clamping and side simultaneously
The most fast wait all problems, make the precision of this product and progress all obtain effectively ensureing.
