Abstract
The utility model discloses a cam rubbing head, its constitution includes: rubbing head base member, deflector, the front end of rubbing head base member the polyurethane layer has, the bottom of rubbing head base member the rubbing head base has, the rubbing head base in the middle of the department open and have the locating hole, the both ends of rubbing head base on open and have the bolt hole, the deflector on in the middle of the department to have a location protruding, the rubbing head base pass through the bolt and be connected with the deflector, the location protruding identical with the locating hole. The front end of this cam rubbing head base member has the working face design of polyurethane layer for circular, and its surface was a little tangent with cam surface all the time when the cam was rotatory, realizes the full week polishing of cam from this, the rubbing head is through cylinder top when tight, and the polyurethane working face produces certain elastic deformation, compresses tightly the abrasive band at cam surface all the time at the rotatory in -process of cam, makes the full weekly form bread of cam draw together the cam waist and all can realize effective polishing.
Description
Technical field
This utility model relates to abrasive band polishing technical field, is specially a kind of cam rubbing head.
Background technology
For improving workpiece surface roughness, reduce friction, loss, reduce noise, high-efficient production technology flow process would generally arrange independent polishing process.Usual machine tool chief axis drives part by setting the positive and negative rotation of the number of turns, and tightens abrasive band by tightening device, makes abrasive band play the cutting to workpiece, polishing function.For making abrasive band efficiently, stably play a role, generally except tightening abrasive band, polishing watt also can be installed, watt compress an abrasive band by polishing, be adjacent to workpiece, make abrasive band efficiently, stably play polishing action.
Being circular axial workpiece to radial section, a polishing watt work surface is designed as circle can realize polishing watt effect.It is non-circular cam parts for radial section, owing to shape is asymmetric, it is impossible to polishing watt is set, only by tightening abrasive band realization polishing.
But when cam rotates all the time by boss, namely basic circle and cam top, hold out against abrasive band, and waist cannot effectively hold out against abrasive band, and waist cannot effectively polish, and effect is excessively poor；Simultaneously because abrasive band length changed in the moment when cam rotates, there is slip on abrasive band and polished part surface, and abrasive band polishing is inefficient, and abrasive band cost is high；When cam rotates, abrasive band moment under tensioned state needs elongation and shortens, and in change procedure, this change causes that abrasive band is easily broken off.Therefore a kind of cam rubbing head of design solves the problems referred to above.
Utility model content
The purpose of this utility model is in that to provide a kind of cam rubbing head, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of cam rubbing head, its composition includes: rubbing head matrix, guide plate, the front end of described rubbing head matrix has layer of polyurethane, the bottom of described rubbing head matrix has rubbing head pedestal, the middle of described rubbing head pedestal has hole, location, the two ends of described rubbing head pedestal have bolt hole, the described middle on guide plate has positioning convex, described rubbing head pedestal is connected with guide plate by bolt, and described positioning convex matches with hole, location.
Preferably, described cam rubbing head, described guide plate two ends have pilot hole, in described pilot hole, there is fairlead, in in described fairlead, there is lead, have cylinder mounting groove below described guide plate middle positioning convex correspondence, in described cylinder mounting groove, cylinder rams is installed.
Preferably, described cam rubbing head, described layer of polyurethane adopts 95 degree of polyurethane of shore, and the work surface that the layer of polyurethane of the front end of described rubbing head matrix is formed is circular.
Compared with prior art, the beneficial effects of the utility model are: the front end of this cam rubbing head matrix has layer of polyurethane work surface and is designed as circle, and when cam rotates, its surface has a bit tangent with cam face all the time, is achieved in the all-round polishing of cam；For the cam of difformity, size, by changing work surface diameter of a circle, it is possible to more effective be polished；Rubbing head is when holding out against by cylinder, and polyurethane work surface produces certain elastic deformation, all the time abrasive band is pressed on cam face, makes the all-round surface of cam include cam waist and all can realize effective polishing in cam rotary course;Abrasive band maintains static in polishing, does not have relative sliding with cam face, and polishing efficiency is higher;Abrasive band at work without elongating or shortening, not easy fracture, improve work efficiency.
