Abstract
The utility model is related to follow-rest field, disclose the follow-rest that a kind of claw carries spring, including follow-rest body, base, the first claw, second claw, 3rd claw, it is characterized in that, spring is housed in the inside of the first claw and the second claw, first claw and the second claw front end are provided with claw head, and claw head material is spheroidal graphite cast-iron.When cutting elongated conical rod shaft, according to the diameter change trend of taper rod shaft, adjustment claw to suitable position；Cut after starting with the even variation of taper rod shaft diameter, claw head can be due to taper rod shaft to its pressure change, the position of claw head is automatically adjusted by internal spring, change support diameter to adapt to the diameter change of taper rod shaft, more preferable supporting role is played, the cutting component of radial direction is offset, it is ensured that elongated conical rod shaft is indeformable, technique is simple, easy to operate.
Description
Technical field
The utility model is related to follow-rest field, more particularly to a kind of claw carries the follow-rest of spring.
Background technology
Follow-rest removes accessory for the general of lathe, especially in the turning process of slender axles, and it is used in Tool in Cutting point
Nearby support workpiece and acted as with knife rest slide carriage one and vertically moved；As follow-rest and workpiece contact position with wear-resisting spheroidal graphite cast-iron or
Bronze is made, the circular arc of bearing claw, in order to avoid abrading workpiece, processing should can be offset using follow-rest in rough turn rear and cylindrical bedding-in
When radial cutting component and workpiece deadweight influence so that reduce cutting vibration and workpiece deformation；But run into actual production
During elongated conical rod shaft, the diameter of axle can uniformly change, and the support diameter after now common follow-rest jaw adjustment is fixed
, it is impossible to meet the effect of support elongated conical rod shaft, it is impossible to cut.
The content of the invention
In order to solve the problem of common follow-rest in the prior art can not complete cutting reducing slender axles, the utility model is carried
A kind of claw has been supplied to carry the follow-rest of spring.
The utility model is realized by following technical proposals：
A kind of claw is carried to be set on the inside of the follow-rest of spring, including base, the c-type body being fixed on base, c-type body
There is the first claw of support workpiece to be processed, the second claw and the 3rd claw, the rear side of the first claw and the second claw is to that should have
Screw-drive mechanism, claw is fixedly connected with screw-drive mechanism, and the first described claw and the second claw top are cylindrical hollow
The front end of structure, the first claw and the second claw is equipped with behind claw head, claw head, claw inside is equipped with spring, the spring
Front end withstand on claw head, the other end withstands on the inner side of c-type body.
It is preferred that, described claw head material is spheroidal graphite cast-iron.
The beneficial effects of the utility model are：The utility model is met behind the follow-rest claw plus by the way of spring
The production of elongated conical rod shaft, can change the fixed diameter of claw automatically, and be close to it with the diameter change of taper rod shaft
In on axle, the cutting component of radial direction is offset, reduces cutting vibrations and deforms；Technique is simple, easy to operate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation after claw partition of the utility model with spring.
In figure：1st, base, 2, c-type body, the 3, first claw, the 4, second claw, the 5, the 3rd claw, 6, claw head, 7, bullet
Spring, 8, screw-drive mechanism.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
A kind of claw is carried in the follow-rest of spring, including base 1, the c-type body 2 being fixed on base 1, c-type body 2
After the first claw 3 of the side provided with support workpiece to be processed, the second claw 4 and the 3rd claw 5, the first claw 3 and the second claw 4
Side is to that should have screw-drive mechanism 8, and claw is fixedly connected with screw-drive mechanism 8, it is characterized in that, the described He of the first claw 3
Second claw 4 top is cylindrical hollow structure, and the front end of the first claw 3 and the second claw 4 is equipped with claw first 6, and first 6 material of claw is
Spheroidal graphite cast-iron is more wear-resisting；Behind claw first 6, spring 7 is housed inside claw, the front end of the spring 7 is withstood on claw first 6,
The other end withstands on the inner side of c-type body 2.
When cutting elongated conical rod shaft, according to the diameter change trend of taper rod shaft, screw-drive mechanism 8 is adjusted so that card
Pawl is to suitable position；Cut after starting with the even variation of taper rod shaft diameter, claw first 6 can be because taper rod shaft be to its pressure
Change, the position of claw first 6 is automatically adjusted by internal spring 7, changes support diameter to adapt to the diameter change of taper rod shaft,
More preferable supporting role is played, the cutting component of radial direction is offset, it is ensured that elongated conical rod shaft is indeformable；When claw head serious wear
When, claw can be taken apart, claw first 6 is individually replaced.
In a word, preferred embodiment of the present utility model is the foregoing is only, it is all according to present utility model application the scope of the claims institute
The equivalent changes and modifications of work, should all belong to the covering scope of the utility model patent.
