Abstract
The invention discloses a surface roll-finishing device for an inner bore of an oil cylinder for a hydraulic press piston. The surface roll-finishing device comprises a bracket and is characterized in that one or a plurality of tumblers are arranged at the front end of the bracket, a roller is rotatably arranged at the front end of the tumbler, a bolt penetrates an hole at the rear end of the tumbler to be bolted with the bracket, a spring is externally sleeved on the bolt and positioned between the rear end of the tumbler and the side wall of the bracket, and a nut pressure spring is screwed at the outer end of the bolt. The surface roll-finishing device can be arranged on the main shafts of power machines such as the ordinary turning lathes or boring lathes, can adjust accurately the rolling size, improve the rigidity, wear resistance and fatigue resistance of the surface of the inner bore, and effectively roll out and polish wave crests of the knife lines of the inner bore surface, thus reducing the surface roughness of the inner bore; besides, the surface roll-finishing device is convenient and simple for use.
Description
Technical field
The invention belongs to machinery processing apparatus, specifically is a kind of hydraulic press piston oil-cylinder hole surface rolling processing device.
Background technology
Processing mainly contains honing (grinding) and rolling and processing dual mode to the hydraulic press manufacturing to piston oil-cylinder hole surface polishing at present.The former must be with special-purpose honing machine or deep hole grinding machine, and can only satisfy the roughness requirement.Latter's processing method is simple, generally loads onto rolling tools and can process on engine lathe or boring spindle, requires can also to improve hole surface hardness, wearability and fatigue resistance etc. simultaneously satisfying roughness.But existing rolling tools, roller are can not mode, and its rolling device volume is bigger, and complex structure uses inconveniently, and supporting power equipment unicity is strong, and versatility is poor, and stress is big, damages workpiece to be machined easily.Existing adjustable have promote by the centre bearing ball that ball regulates, what use is the planetary structure principle, flexibility between ball and the ball is big, degree of regulation is poor, influences the roll extrusion effect, also has a kind of flexible jointing formula regulative mode, the structure more complicated, and every joint fixed size can not be carried out trickle adjusting, and applicability is not strong.
Summary of the invention
The purpose of this invention is to provide hydraulic press piston oil-cylinder hole surface rolling processing device, can accurately regulate the roll extrusion size, can improve bore area hardness, wearability and fatigue resistance, reduce inner bore surface roughness, use simple and convenient.
Technical scheme of the present invention is as follows:
Hydraulic press piston oil-cylinder hole surface rolling processing device, comprise support, it is characterized in that described support front end is rotatablely equipped with one or more pivoted arms, described pivoted arm front end is rotatablely equipped with roller, the perforate and the support that have bolt to pass the pivoted arm rear end screw togather, bolt is with spring outward, and between pivoted arm rear end and rack side wall, the bolt outer end is rotary with the nut holddown spring.
Described hydraulic press piston oil-cylinder hole surface rolling processing device is characterized in that described pivoted arm front end has rotating shaft, and described roller is installed in the rotating shaft by bearing, and described roller wheel rim is the arcuation projection.
Described hydraulic press piston oil-cylinder hole surface rolling processing device is characterized in that described pivoted arm is two, is symmetrical arranged on support.
Described hydraulic press piston oil-cylinder hole surface rolling processing device is characterized in that described roller housing is loaded in the rotating shaft, and the roller both sides are equipped with dust cap.
The roller that the present invention makes with the instrument steel carries out roll extrusion, rolles over light at mechanical bore area, makes surface layer material produce plasticity and flows, and effectively hole surface knife mark crest is planished polishing, reduces inner bore surface roughness.Can on power equipment main shafts such as general engine lathe or boring machine, install and use, can accurately regulate the roll extrusion size, can improve bore area hardness, wearability and fatigue resistance, use simple and convenient.Inner bore surface roughness through rolling and processing reaches Ra＞0.08-0.63 μ m, and surperficial hardening depth reaches 0.2-1.5mm, hardenability: 10%-40%.
