Abstract
It can prevent the machine of workpiece deformation from adding fixture, including scroll chuck, flange block and clamp block；The claw that can be moved radially there are three being set on scroll chuck；Flange block is plate of the end face in fan annular, which is provided with multigroup location hole, and three pieces flange block is respectively and fixedly connected on three claws of scroll chuck, and uniformly distributed in a ring along the center of three claws；Clamp block there is the intrados contacted with inner hole of workpiece and/or the extrados contacted with excircle of workpiece, fixture number of blocks to have three pieces, three pieces of clamp blocks are bolted respectively on three pieces flange block in fan Ring-cylindrical.When clamping of the present invention, the intrados or extrados of three pieces of clamp blocks are contacted with workpiece, compared to using the direct clamping workpiece of scroll chuck, the contact area bigger of clamp block and workpiece, the clamping force of bigger can be applied, clamping is more firm, is not in the problem of workpiece clamp is gone out gravure or folder deformation, to be suitable for the clamping of thin-wall sleeve cylindrical work pieces.
Description
Technical field
The present invention relates to machine plus clamp art, especially a kind of machine preventing workpiece deformation adds fixture.
Background technology
Most common fixture is scroll chuck on lathe, and existing scroll chuck is in clamping workpiece, claw
It is smaller with the contact area of workpiece, it is firmly slightly larger to be easy for deforming workpiece clamp in the yielding workpiece of clamping thin-walled, firmly
Slightly smaller then clamping workpiece is insecure, is easy to fly out.
Invention content
The purpose of the present invention is overcome the deficiencies in the prior art, and providing a kind of prevents the machine of workpiece deformation from adding folder
Tool, it solves existing scroll chuck in the yielding workpiece of clamping thin-walled, the problem of being easy to deform workpiece clamp.
The technical scheme is that：Can prevent the machine of workpiece deformation from adding fixture, including scroll chuck, flange block and
Clamp block；
The claw that can be moved radially there are three being set on scroll chuck；
Flange block is plate of the end face in fan annular, which is provided with multigroup location hole, every group of location hole is respectively provided at flange block
On the circular arc line of the concentric circles of different radii, flange number of blocks has three pieces, three pieces flange block to be respectively and fixedly connected to the three of scroll chuck
On a claw, and it is uniformly distributed in a ring along the center of three claws；
Clamp block has the intrados contacted with inner hole of workpiece and/or the extrados contacted with excircle of workpiece in fan Ring-cylindrical,
Fixture number of blocks has three pieces, and three pieces of clamp blocks are bolted respectively on three pieces flange block.
The further technical solution of the present invention is：Clamp block one end is equipped with the connected unit extended radially, is set in connected unit
There are mounting hole, mounting hole to match with one group of location hole on flange block；
One end of the connected unit of clamp block is contacted with flange block, then is bolted on flange block, and the bolt is worn successively
The two is fixedly connected by the mounting hole for crossing clamp block with the location hole of flange block.
The further technical solution of the present invention is：Every group of location hole of flange block includes at least two bolts hole and a pin
Hole.
The further technical solution of the present invention is：Circular arc line radius where any one group of flange block is positioned with adjacent sets
The difference between circular arc line radius where hole is definite value.
The further technical solution of the present invention is：The end face of flange block is in fan annular, the value of central angle α, α
90-120 °, in fan annular, the value of central angle β≤α, β are 90-120 ° for the end face of clamp block.
The present invention has the following advantages that compared with prior art：
1, when clamping, the intrados or extrados of three pieces of clamp blocks are contacted with workpiece, compared to using the direct clamping work of scroll chuck
The contact area bigger of part, clamp block and workpiece, can apply the clamping force of bigger, and clamping is more firm, be not in by workpiece clamp
The problem of going out gravure or folder deformation, is suitable for the clamping of thin-wall sleeve cylindrical work pieces.
2, flange block is equipped with multigroup location hole, can be adapted to the clamp block of different size, when clamping workpiece, you can passes through
Clamp block expands the clamping size limit of scroll chuck, is suitable for the clamping of heavy parts, also can be by selecting Different Rule
Clamp block realizes the clamping of special-shaped workpiece.
Below in conjunction with figure, the invention will be further described with embodiment.
