Abstract
The utility model discloses a high-precise thin-walled sleeve lathe processing soft claw clamping structure, which comprises a disc body and at least three claws which are arranged on the disc body, wherein, each claw is connected with a soft claw, and one side, which faces towards the work piece, of each soft claw is provided with an arc surface with two clamping corner points, so that three soft claws have six points to be clamped. The welding soft claw structure not only can ensure adequate clamping force, but also can reduce the deformation of the work piece.
Description
Technical field
The utility model relates to a kind of machine tool element, especially a kind of scroll chuck.
Background technology
Produce in the actual production of revolving body at lathe, adopting radius-thickness ratio is the blank of 0.0857 seamless steel pipe, then rigidity is very poor, with general scroll chuck chucking, all between 0.15-0.2, clamping force is big more for the triangular deformation deviation that produces in the turning process, out-of-roundness deviation, and then deviation is also big more, and clamping force can not be too little, otherwise just can't carry out turning processing.
The utility model content
The purpose of this utility model provides and a kind ofly can increase clamping force, can reduce the novel scroll chuck of workpiece deformation again.
For achieving the above object, the utility model adopts following technical scheme: the soft pawl chucking of a kind of high accuracy thin-walled cover Vehicle Processing structure, comprise at least 3 claws that are provided with on disk body and the disk body, all be connected with soft pawl on each claw, described each soft pawl is the arcwall face of two chucking angle points towards a side of workpiece.
Described claw is 3, is with soft pawl to be welded to connect, and the arc length of described soft pawl is not less than 1/8 of workpiece circumference.
During use, between each soft pawl, turning diameter is less than diameter of work 0.5-1mm with workpiece clamp, can not be greater than reference surface diameter, then but each chucking angle point of soft pawl is with regard to multiple spot chucking workpiece, and the radian of described soft pawl is not less than 1/8 of workpiece circumference, can make the workpiece multiple spot stressed evenly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Comprise 3 claws 2 that are provided with on disk body 1 and the disk body 1 by the soft pawl chucking of high accuracy thin-walled cover Vehicle Processing structure shown in Figure 1, each claw 2 inboard all is welded with soft pawl 3, described each soft pawl 3 is the arc that comprises two chucking angle points 4 towards a side of workpiece 5, and the arc length of described soft pawl 3 is not less than 1/8 of workpiece 5 circumference.
During use, workpiece 5 is clipped between each soft pawl 3, turning diameter is less than workpiece 5 diameter 0.5-1mm, can not be greater than reference surface diameter, but each chucking angle point 4 of then soft pawl 3 multiple spot chucking workpiece 5 just.
Claims (2)
1. the soft pawl of high accuracy thin-walled cover Vehicle Processing tightens structure, comprise at least 3 claws that are provided with on disk body and the disk body, all be connected with soft pawl on each claw, it is characterized in that: described each soft pawl is the arcwall face of two chucking angle points towards a side of workpiece.
2. the soft pawl chucking of high accuracy thin-walled cover as claimed in claim 1 Vehicle Processing structure, it is characterized in that: described claw is 3, is with soft pawl to be welded to connect, the arc length of described soft pawl is not less than 1/8 of workpiece circumference.
