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 multiple groups 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 the utility model clamping, 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 of clamp block and workpiece is bigger, bigger clamping force can be applied, clamping is more firm, is not in the clamping suitable for thin-wall sleeve cylindrical work pieces the problem of workpiece clamp is gone out gravure or folder deformation.
Description
Technical field
The utility model relates to machine plus clamp arts, especially a kind of to prevent the machine of workpiece deformation from adding folder
Tool.
Background technique
The 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 easily-deformable workpiece of clamping thin-walled, firmly
Slightly smaller then clamping workpiece is insecure, is easy to fly out.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a kind of machine that can prevent workpiece deformation
Add fixture, it solves existing scroll chuck in the easily-deformable workpiece of clamping thin-walled, is easy the problem of deforming workpiece clamp.
The technical solution of the utility model is: 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 multiple groups location hole, every group of location hole is respectively provided at flange
On the circular arc line of the concentric circles of the different radii of block, flange number of blocks has three pieces, and three pieces flange block is respectively and fixedly connected to scroll chuck
Three claws on, 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 contacts with excircle of workpiece outer in fan Ring-cylindrical
Cambered surface, fixture number of blocks have three pieces, and three pieces of clamp blocks are bolted respectively on three pieces flange block.
The further technical solution of the utility model is: clamp block one end is equipped with the connected unit extended radially, connected unit
It is equipped with mounting hole, mounting hole matches 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, the bolt according to
The two is fixedly connected by the secondary mounting hole across clamp block with the location hole of flange block.
The further technical solution of the utility model is: every group of location hole of flange block includes at least two bolts hole and one
A pin hole.
The further technical solution of the utility model is: circular arc line radius and adjacent sets where any one group of flange block
The difference between circular arc line radius where location hole is definite value.
The further technical solution of the utility model is: the end face of flange block is in fan annular, the value of central angle α, α
It is 90-120 °, in fan annular, the value of central angle β≤α, β are 90-120 ° for the end face of clamp block.
The utility model has the advantages that compared with prior art
1, when clamping, the intrados or extrados of three pieces of clamp blocks are contacted with workpiece, are directly filled compared to using scroll chuck
The contact area of folder workpiece, clamp block and workpiece is bigger, can apply bigger clamping force, clamping is more firm, is not in by work
Part presss from both sides out the problem of gravure or folder deformation, the clamping suitable for thin-wall sleeve cylindrical work pieces.
2, flange block is equipped with multiple groups location hole, can be adapted to the clamp block of different size, when clamping workpiece, can pass through
Clamp block expands the clamping size limit of scroll chuck, suitable for the clamping of heavy parts, can also pass through selection Different Rule
The clamping of clamp block realization special-shaped workpiece.
The utility model is further described below in conjunction with figure and embodiment.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model；
Fig. 2 is schematic perspective view of the utility model under another visual angle.
