Abstract
A rigid outer circle rolling tool comprises a rolling wheel, a clamp rack, and a core shaft, and is characterized in that the core shaft is welded with the rolling wheel as a whole at one end; two back-to-back centripetal ball bearings, having a spacer bushing therebetween, are arranged on the joint of the other end of the core shaft and the inner hole of the clamp rack; and the rolling wheel is made of YT5 and YT 15 hard alloy. The utility model is used for rolling process of the outer circle surface of bearing-like parts to improve the surface roughness, wear resistance and fatigue strength, with advantages of simple structure, convenient operation, and adjustable bearing gaps, and can ensure that the rolling accuracy will not decrease after long-time use.
Description
Technical field
The utility model relates to a kind of cylindrical rigidity rolling tools, is used for the outer round surface of axial workpiece is carried out rolling and processing.
Background technology
For improving axial workpiece surface roughness, wearability and fatigue strength, often adopt rolling and processing.The present outer circle rolling tool that generally uses, structure are complicated, and after long-term the use, the mandrel of installation roller and the fit clearance of holding frame are increasing, but can't adjust, and cause the roll extrusion precision to reduce.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, can not reduce the cylindrical rigidity rolling tools of roll extrusion precision after long-term the use.
The technical solution of the utility model is: cylindrical rigidity rolling tools, comprise roller, holding frame, mandrel, improvements are that an end and the roller of mandrel is integrally welded, and the cooperation place of the other end and holding frame endoporus is provided with the angular contact ball bearing of a pair of back-to-back assembling, and spacer is arranged between two bearings.
The above-mentioned rollers material is a kind of in YT5, the YT15 carbide alloy; One end of holding frame endoporus is provided with end cap and adjusts pad.
The utility model is not only simple in structure, compact, easy to operate, and control the length of two angular contact ball bearing spacer sleeves and the thickness of hole end surface pad, just can adjust the bearing clearance, roller is selected the high duty alloy material for use in addition, can guarantee can not reduce the roll extrusion precision after long-term the use.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Consult accompanying drawing, integrally welded by the roller 1 that the YT15 carbide alloy makes with an end of mandrel 2, A place brazing one is enclosed in the drawings, the other end of mandrel 2 is contained in the endoporus of holding frame 8, the cooperation place is provided with the angular contact ball bearing 3 of two back-to-back assemblings, and spacer 4 is arranged between two bearings, and axle head has locking nut 5 that bearing inner race is compressed, one end of holding frame endoporus is provided with end cap 7 and adjusts pad 6, and the outer ring of bearing is compressed.During use, the roll extrusion clamping workpiece on lathe spindle, on knife rest, just can be carried out rolling and processing to workpiece with this instrument clamping.
Claims (3)
1, a kind of cylindrical rigidity rolling tools comprise roller, holding frame, mandrel, it is characterized in that an end and the roller of mandrel is integrally welded, and the cooperation place of the other end and holding frame endoporus is provided with the angular contact ball bearing of a pair of back-to-back assembling, and spacer is arranged between two bearings.
