Mandril can cause machining accuracy to be deteriorated with power vertical tremor is cut, and shake knife even workpiece is scrapped.
[utility model content]
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of Wedge type Auxiliary support machine
Structure, including spring base, mandril, compressed spring, the compressed spring and mandril are set in the spring base, under the mandril
End is contacted with the compressed spring, and the upper end of the mandril is contacted with workpiece, which further includes inclined wedge, locking screw
Bar, locking bed, wedge groove are set on the side wall of the mandril, and the locking bed is set to the side of the spring base, described
Tie down screw is through the locking bed and extend into the spring base, and the inclined wedge is arranged in spring base, and the inclined wedge is set
It sets between tie down screw and mandril, the inclined wedge is close to wedge groove under the promotion of tie down screw and locks mandril.
Preferably, the lower section of the spring base is equipped with spring stop, the lower end of the compressed spring is against spring stop
On.
Preferably, the locking bed is fixed on the side wall of spring base by multiple bolts.
Preferably, the head annular knurl of the tie down screw.
Preferably, the lower section of the spring stop is equipped with multiple support legs.
The utility model has the beneficial effects that compared with prior art, a kind of Wedge type auxiliary branch provided by the utility model
Support mechanism, easy to assembly quick, laborsaving, the head annular knurl processing of tie down screw is not required to spanner, i.e., available hand locks mandril；
After workpiece is put into clamp body, mandril is pressed downward tightly, adjusts tie down screw, and inclined wedge is pushed to lock mandril, when after processing is completed,
It removes workpiece, unclamps tightening screw rod, under spring force, mandril opens inclined wedge, while mandril affranchises state, this side
Case Wedge type mechanism friction power is big, and self-locking performance, self-alignment are good, high reliablity, can meet the processing of larger cutting force, improves fixture
Stability and rigidity reduce workpiece scrappage to guarantee machining accuracy.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.

[specific embodiment]
To make the objectives, technical solutions and advantages of the present invention clearer, below by accompanying drawings and embodiments,
The present invention will be further described in detail.However, it should be understood that specific embodiment described herein is only used to solve
The utility model is released, the range being not intended to limit the utility model.In addition, in the following description, being omitted to known features
With the description of technology, to avoid the concept for unnecessarily obscuring the utility model.
Refering to Fig. 3 and Fig. 4, the utility model embodiment provides a kind of Wedge type auxiliary support mechanism, including spring base 1,
Mandril 3, compressed spring 6, the compressed spring 6 and mandril 3 are set in the spring base 1, the lower end of the mandril 3 with it is described
Compressed spring 6 contacts, and the upper end of the mandril 3 contacts with workpiece 8, the auxiliary support mechanism further include inclined wedge 2, tie down screw 4,
