Description
Technical field
The utility model relates to hole neck bush drawing extracting tool, specifically a kind of bushing dismounting instrument of stretching drawing type on a kind of automobile.
Background technology
At present, in the use procedure of automobile, after the lining in control arm lining, bridge and vehicle frame connection bracket damages, need to dismantle lining, to change.But the interference fit between lining and lining cylinder makes lining be not easy very much dismounting.
With tool ejector linings such as traditional hand hammer, chisels, waste time and energy, dismounting difficulty, and greatly easily damage auto parts and components due to hammer force.
Summary of the invention
The utility model provides that a kind of structure is simple, the stretching formula bushing dismounting instrument of economical, easy to operate energy lining for convenience detach, overcomes the above-mentioned deficiency of tradition dismounting lining method.
Technical solutions of the utility model accompanying drawings is as follows: this extracting tool comprises stopping means, augmentor, top cartridge and pull rod device four parts from front to back successively; Wherein said stopping means is screwed by two acorn nuts 1 and isometric studs 2 and forms; Described augmentor is screwed by two handles 3 and forms on handle nut 4; Described top cartridge is formed by pushing up cover 5, the top cylinder 7 be threaded with top cover 5 and thrust ball bearing 6 therebetween; Described pull rod device is made up of screw rod 11, three pulling claws 10, two small size springs 8 and a large size spring 9, three described pulling claws 10 are evenly arranged on screw rod 11 around, and described two small size springs 8 and large size spring 9 are arranged in the annular groove of three pulling claws 10 and head and the tail are hooked together; Described screw rod 11 is threaded connection through top cartridge and coordinates with augmentor; Described screw rod 11 is fixed by isometric studs 2 and acorn nut 1; Described augmentor is threaded connection the axial force promotion top cylinder 7 of transmission and the relative motion of pulling claw 10.
In described augmentor, handle 3 and handle nut 4 are replaced by a square nut 12.
The beneficial effects of the utility model are: the utility model can dismantle plurality of specifications lining, structure is simple, technique is simple, cost is low, easy to operate, time saving and energy saving.

Detailed description of the invention
Consult Fig. 1, Fig. 2, Fig. 3, Fig. 4, this extracting tool comprises stopping means, augmentor, top cartridge and pull rod device four parts from front to back successively.Wherein said stopping means is screwed by two acorn nuts 1 and isometric studs 2 and forms; Described augmentor is screwed by two handles 3 and forms on handle nut 4; Described top cartridge is formed by pushing up cover 5, the top cylinder 7 be threaded with top cover 5 and thrust ball bearing 6 therebetween; Described pull rod device is made up of screw rod 11, three pulling claws 10, two small size springs 8 and a large size spring 9, during assembling, first three pulling claws 10 are evenly placed in around screw rod 11 assigned address, then successively described two small size springs 8 and large size spring 9 are arranged in the annular groove of three pulling claws 10 and head and the tail are hooked together; Described screw rod 11 is threaded connection through top cartridge and coordinates with augmentor; Described screw rod 11 is fixed by isometric studs 2 and acorn nut 1; Described augmentor is threaded connection the axial force promotion top cylinder 7 of transmission and the relative motion of pulling claw 10.
Consult Fig. 1, Fig. 3, Fig. 4, augmentor is two handles 3 and the handle nut 4 be threaded with handle 3 or square nut 12, realizes twisting during user's nut 12 by instruments such as monkey wrenches.
Consult Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, during use, by the screw rod 11 of pull rod device successively through top cartridge, augmentor, and screw out from augmentor, then isometric studs 2 is inserted in the hole of screw rod 11, then be screwed to the two ends of isometric studs 2 with two acorn nuts 1.Manually pulling claw 10 is shunk, be placed in the lining that will dismantle, pulling claw 10 is pushed to bottom to bush inside, pulling claw 10 will automatically open under the convergent force effect of small size spring 8, and is hooked in jacket wall, the instrument twisting square nuts 12 such as up time rotary handle 3 or use spanner, top cylinder 7 is made to withstand on lining cylinder, continue to rotate augmentor, the axial force being threaded connection transmission promotes the relative motion of top cylinder 7 and pulling claw 10, thus is pulled out by lining.
