Abstract
The utility model relates to an anti-jamming limit mechanism for a precise tapered roller production line. The anti-jamming limit mechanism is characterized by comprising a pass-stop retaining plate right above a flexible chain plate conveying belt. The pass-stop retaining plate is provided with a limit edge which can move vertically. The initial position of the limit edge is higher than the upper edge of the small end of a tapered roller and lower than the upper edge of the large end of the tapered roller. The anti-jamming limit mechanism has the advantages that an inertia retaining plate is used to limit the tapered roller so as to prevent the tapered roller from flying out of the conveying belt due to excessively-large inertia, and tapered roller scattering and collision are reduced; the limit edge of the pass-stop retaining plate can move vertically, the tapered roller with the small end in front can pass, the tapered roller with the large end in front is stopped, and equipment damage and product scrap caused by the fact that the dislocated tapered roller enters the grinding machine of the next working procedure can be avoided.
Description
Technical field
The utility model relates to a kind of bearing roller production facilities, particularly the anti-jamming stop gear of a kind of precision tapered roller manufacturing line.
Background technology
Bearing is the important foundation parts of all kinds of mechanized equipments, and its precision, performance, life and reliability play conclusive effect to the precision of main frame, performance, life and reliability.In engineering goods, bearing belongs to high-precision product, not only need the comprehensive support of the subjects theories such as mathematics, physics, and need material science, heat treatment technics, detailed manufacture and measurement technique, Numeric Control Technology and actv. numerical method and the powerful subjects such as computer technology to serve for it, so bearing is again a product that represents national science and technology strength.
In the last few years, world-famous enterprise entered one after another Chinese bearing market and set up production base, as the NSK company of Sweden SKF group, German Schaeffler Group, U.S.'s The Timken Company, Japan, NTN company etc.These companies are not only the whole world and manage, and are that manufacture in the whole world, and they rely on brand, equipment, technology, fund and production-scale advantage, have launched keen competition with domestic bearing enterprise.Therefore, domestic enterprise wants and external advanced bearing brand competition, even surmounts, also need to be in the road for development of the aspect experience a very long times such as technology.
Wherein, roller belongs to the most important components that rolling body and steel ball are both bearing, be also that bearing industry is used maximum rolling bodys, and the quality of roller directly affects bearing quality.
In the production procedure of roller, need to pass through the multiple working procedures such as hard grind, ball basal plane mill, super grinding; When roller circulates between the grinding machine of each procedure, domestic traditional method is all to carry out a dead lift transfer by transfer cart, and not only efficiency is low, and easily causes colliding with of roller surface in circular flow, has greatly affected the quality of product.Therefore how to eliminate domestic roller produce in the problem that conforming product rate is low, bump injury phenomenon is serious that causes of intrinsic unit operation production model, what be that we face is also the problem that can improve by technology innovation.
Domestic also have the more well-known roller manufacturing enterprise of part to use roller to manufacture conveyor line, it is by carrying out roller automation on line between the centerless grinder in realization grinding, ball cardinal plane grinding machine, superfinishing grinding machine, utilization has the nonmetal flexible chain plate conveyor belt of V-type groove, and be equipped with corresponding intermittent discharge mechanism and sensor, control system by the orderly grinding machine that is transported to subsequent processing of roller, and then realize automatic continuous production, significantly promote production efficiency, and avoided the bump injury phenomenon of roller surface.
Still there is certain defect in domestic taper roller automation on line at present: intermittent discharge mechanism is distributed in flexible chain sheet conveying belt, form multi-buffer feeding, its structure mainly comprises the releasing bracket being fixed in flexible chain sheet conveying belt frame, be arranged on blowing cylinder and blowing block on releasing bracket, utilize the sensor on relevant position to detect the roller position on flexible chain sheet conveying belt, by control system Control and Schedule blowing cylinder, moved, drive blowing block to leave flexible chain sheet conveying belt, realize stopping or letting pass of roller.
In said structure, for avoiding blowing block when action to cause scraping damage to roller, it all adopts nylon material; The roller at rear is blocked in after blowing block, and in the effect of flexible chain sheet conveying belt, next directes reach nylon blowing block; And in nylon blowing block retraction process, because the effect of friction force can pull roller together to move, and then make roller shift out flexible chain sheet conveying belt to cause roller to collide with, also or cause the roller dislocation of turning around, flow into next procedure and directly make roller scrap.
Therefore, how to avoid roller to misplace in automation on line course of conveying imperative, through retrieval pertinent literature, do not find the anti-jamming stop gear of precision tapered roller manufacturing line identical with technical scheme in the utility model.
