Description
Technical field
It the utility model is related to a kind of fixture, and in particular to a kind of folder for avoiding shape clamping deformation inside and outside valve body smart car
Tool.
Background technology
It is ZL101A that aluminum casting, which turns to valve body material, and tensile strength is more than 295MPa, lighter weight, but material is softer has
Certain elasticity.Profile fashionable dress folder blank is cylindrical in smart car, easily produces clamping deformation.Due to the main Working position of valve body
Such as cylindrical, end face, endoporus, internal thread, interior outer channel, the size being related to is more, and it is complicated, valve body wall thickness is relatively thin, add
Man-hour easily produces clamping deformation, such as the change of endoporus circularity greatly, makes bearing hole dimension overproof, causes product rejection, both wasted processing
Time, also increase cost.
The content of the invention
The purpose of this utility model is：There is provided a kind of simple in construction, novel in design；In the course of work, pass through scattered folder
Clamp force, can effectively solve aluminum casting and turn to valve body because material is softer, cause what clamping was also easy to produce problem on deformation to avoid valve body smart
The fixture of in-car profile clamping deformation.
The technical solution of the utility model is：
A kind of fixture for avoiding shape clamping deformation inside and outside valve body smart car, it is by rebound, roller ball fixed seat, rolling
Ball, ball-joint master jaw, clamp body, spherical joint seat, claw and locating piece are formed；It is characterized in that：Dress is evenly equipped with clamp body
Distribution, roller ball, the clamp body of roller ball fixed seat front end are provided with by roller ball fixed seat on the clamp body in pilot hole
Interior to be provided with ball-joint master jaw by spherical joint seat, ball-joint master jaw is connected with roller ball, is passed through on ball-joint master jaw
Fixing bolt is installed with claw, and claw extends to clamp body outer end through pilot hole, is provided with the clamp body between claw
Locating piece, roller ball are fixed on the clamp body of base rear end and are provided with rebound by bolt, set in described roller ball fixed seat
Connecting bolt is equipped with, one end of connecting bolt is extended to the over cab apron outer end, and the connecting bolt for being extended to the over cab apron outer end is provided with
Locking nut.
The advantages of the utility model, is as follows：
This can be avoided the clamp structure of shape clamping deformation inside and outside valve body smart car compact, convenient mounting and clamping, can effectively be reduced the number of rejects and seconds
Rate, reduce cost；It need not be remodeled during the Product processing of adjoining dimensions to foreign round, it is convenient and swift.During work, lathe oil cylinder, which drives, to be connected
Connecting bolt is axially moved, and so as to drive roller ball fixed seat to move, claw is closed by ball-joint master jaw in roller ball and ball
Claw can be achieved in ball-type cooperation at section seat has certain beat function in circumferential and axial direction, fixture is unclamped or is pressed from both sides
Tightly.When claw and valve body（Workpiece）During periphery contact start stress, claw can carry out circumference automatically and be adjusted axially with more preferable
Fitted with valve body periphery, to increase holding area, so as to reach the effect of scattered clamping force；And then solves existing casting
Aluminum component turns to valve body because material is softer, the problem of causing clamping to be also easy to produce deformation, valve body smart car is turned to especially suitable for aluminum casting
Clamping uses.

Embodiment
This can avoid the fixture of shape clamping deformation inside and outside valve body smart car by rebound 1, roller ball fixed seat 2, roller ball 3,
Ball-joint master jaw 4, clamp body 5, spherical joint seat 6, claw 7 and locating piece 8 are formed；Triangular shape is provided with dress on clamp body 5
Distribution 9, roller ball 3 is provided with by roller ball fixed seat 2 on the clamp body 5 in pilot hole 9, the front end of roller ball fixed seat 2
Ball-joint master jaw 4 is provided with by spherical joint seat 6 in clamp body 5, is provided between ball-joint master jaw 4 and spherical joint seat 6
Sealing ring.Ball-joint master jaw 4 is connected with roller ball 3, and claw 7 is installed with by fixing bolt on ball-joint master jaw 4,
Claw 7 extends to the outer end of clamp body 5 through pilot hole 9, is provided with locating piece 8 on the clamp body 5 between claw 7, roller ball is fixed
Rebound 1 is provided with by bolt on the clamp body 5 of 2 rear ends of seat.
Connecting bolt 10 is provided with roller ball fixed seat 2, one end of connecting bolt 10 is extended to the over the outer end of cab apron 1, prolonged
Extend and be provided with locking nut 11 on the connecting bolt 10 of the outer end of rebound 1.
When this can be avoided the fixture of shape clamping deformation inside and outside valve body smart car from working, it is packed in by bolt on lathe, and will
Connecting bolt 10 is connected with lathe pull bar, then by workpiece 12 to be processed（Aluminum casting turns to valve body）Reach 3 claws 7 it
Between, until the tail plane of workpiece 12 is close on locating piece 8, start lathe, when lathe oil cylinder drive pull bar axially moves, band
Dynamic connecting bolt 10 axially moves, so as to drive roller ball fixed seat 2 to move, because claw 7 is existed by ball-joint master jaw 4
Ball-type at roller ball 3 and spherical joint seat 6 coordinates achievable claw 7 having certain beat function in circumferential and axial direction, thus
Claw 7 is set to unclamp or clamp.When claw 7 and during 12 periphery contact start stress of workpiece, claw 7 can carry out automatically it is circumferential and
It is adjusted axially preferably to be fitted with the periphery of workpiece 12, thus increases holding area, so as to reaches the effect of scattered clamping force
Fruit；And then solve existing aluminum casting and turn to valve body because material is softer, the problem of causing clamping to be also easy to produce deformation, and artificial behaviour
The uneven and caused problem on deformation of clamping force caused by work；Valve body smart car clamping is turned to especially suitable for aluminum casting to use.
The clamping position of the fixture is that the blank of workpiece 12 is cylindrical, and claw 7 is when unclamping and workpiece 12 is cylindrical has between 1-2mm
Gap, can without consider because casting die cavity it is more caused by blank uniformity difference the problem of.
Claw 7 is coordinated by ball-type of the ball-joint master jaw 4 at roller ball 3 and spherical joint seat 6 realizes claw 7 in circumference
And axially it can eliminate workpiece 12 with during beat and divide pattern draft problem caused by mould.Solve existing aluminum casting to turn
To valve body because material is softer, the problem of causing clamping to be also easy to produce deformation, the fixture can be adjusted according to the excircle dimension of different parts
The stroke of claw 7 is the processing that can be applied to various parts.
