Abstract

The invention discloses heat treatment quenching equipment for small and medium-sized bearing rings. A driving chain wheel and a driven chain wheel are arranged in an oil groove; the driving chain wheel is fixed with a rotating shaft of a motor; the motor is positioned at the lower part of the oil groove; a chain is tensioned on the driving chain wheel and the driven chain wheel; a guide rail is fixed in the oil groove; each of heat treatment devices is composed of a connecting plate, two roll shafts, two rollers and two high temperature-resistant bearings; the connecting plates are welded and fixed on the chain; outer rings of the high temperature-resistant bearings are welded and fixed on the connecting plates; the roll shafts are welded and fixed on inner rings of the high temperature-resistant bearings; the rollers are fixed at the other ends of the roll shafts, and are positioned on the guide rail; stop edges are formed on each of the roll shafts; the stop edges of the adjacent two roll shafts are leant to each other; workpieces are positioned on the adjacent two roll shafts; and the plurality of heat treatment devices are connected to the chain. The heat treatment quenching equipment prevents the problems of high manual workload and workpiece damage proneness in a traditional quenching method, improves the production efficiency, and enhances the quality of the bearing rings after the bearing rings are quenched.

Description

Middle-size and small-size bearing ring heat treatment quenching equipment

Technical field:

The present invention relates to bearing ring production technical field, heat-treat equipment used while quenching more specifically to a kind of middle-size and small-size bearing.

Background technology:

CN201183812Y discloses a kind of middle-size and small-size bearing ring heat-treatment quenching machine, and the heat-treatment quenching method that it is relatively traditional, has reduced hand labor intensity, has improved production efficiency, and the rear qualification rate of bearing ring quenching is obviously improved.Its weak point is: the bearing ring limited amount of 1, processing in the unit time, production efficiency needs further to be improved.2,, while quenching in oil groove, the shake of bearing ring workpiece not, is unfavorable for improving the quality after bearing ring quenches.

Summary of the invention:

Object of the present invention is exactly the deficiency for prior art, and a kind of middle-size and small-size bearing ring heat treatment quenching equipment is provided, it has avoided in traditional quenching method hand labor intensity large, the problem of workpiece easy damaged, improve production efficiency simultaneously, improved the quality after bearing ring quenches.

Technology solution of the present invention is as follows:

Middle-size and small-size bearing ring heat treatment quenching equipment, comprises oil groove, is provided with drive sprocket and driven sprocket in oil groove, the rotating shaft of drive sprocket and motor is fixed together, motor is placed in the bottom of oil groove, and chain tension, on drive sprocket and driven sprocket, is fixed with guide rail in oil groove;

Each thermal treatment unit is made up of web plate, two roll shafts, two rollers and two high temperature resistant bearings, web plate is weldingly fixed on chain, on web plate, be welded with the outer ring of high temperature resistant bearing, on the inner ring of high temperature resistant bearing, be welded with roll shaft, the other end of roll shaft is fixed with roller, two rollers are placed on guide rail, and each roll shaft all forms rib, and the rib of adjacent two roll shafts is close together; Workpiece is placed on two adjacent roll shafts, and several thermal treatment units are connected on chain.

Described roller is steel cylindrical entity, and roller is weldingly fixed on roll shaft, and guide rail is kidney-shaped ring-shaped guide rail, is adhesively fixed with one deck rubber spacer above guide rail.

Beneficial effect of the present invention is:

1,, compared with the middle-size and small-size bearing heat-treatment quenching method of tradition, the present invention need not people holds by hand bearing ring and shakes in oil groove, so it has avoided in traditional quenching method hand labor intensity large, and the problem of workpiece easy damaged.

2, compared with prior art, the present invention can the more bearing ring of primary treatment, so improved production efficiency.

3, in prior art in the oil of 30～80 DEG C when heat-treatment quenching, bearing ring only has rotation action, not shake action, and roll shaft of the present invention is in rotating, due to the walking of chain, the action of shake up and down that roll shaft is certain along with chain has, so more meets the requirement that bearing ring quenches, and contributes to like this to improve the quality after bearing ring quenches.

4, on roll shaft, be provided with rib, can prevent that workpiece from dropping from roll shaft when thermal treatment is walked about in oil groove.
