Abstract
The invention discloses a grinding wheel grinding roller for grinding a grinding wheel which is used for grinding stop edges of inner-ring roller path and outer-ring roller path of a short cylindrical bearing. Front projection of the grinding roller is H-shaped, a central hole (4) is reserved at the center of a gyration, an annular groove (2) is arranged on the middle portion of an outer ring, a grinding wheel grinding position (6) is arranged in the groove (2), and the width B of the groove (2) is identical to the width B of a dressed grinding wheel (5) and the width B of the roller paths with grinded stop edges of the grinding wheel (5). Via the grinding wheel dressed by the grinding roller, two stop edges on the inner-ring, outer-ring roller paths can be grinded after one-step positioning, the quality problem that width error of an inner ring and the outer ring is duplicated on the grinded width of the stop edges is solved, and full automatic production can be realized.
Description
Technical field
The present invention relates to a kind of profiling mechanism basic part, be specifically related to a kind of contact roller for dressing that the emery wheel of the inside and outside circle raceway of grinding cylindrical bearing rib is repaired.
Background technology
The inner ring of cylindrical bearing or outer ring raceway are designed to two ribs, need rib is carried out grinding to control the raceway width.Traditional lip grinding method is: two end faces with inside and outside circle are respectively positioning datum, the corresponding rib of grinding; An inside and outside circle raceway rib needs twice location, twice grinding, and inside and outside circle width dimensions error is duplicated at the lip grinding width qualitatively, and grinding accuracy is poor, efficient is low, is difficult to realize full-automatic production.
Summary of the invention
In order to solve the background technology problem, the invention discloses a kind of contact roller for dressing that the emery wheel of the inside and outside circle raceway of grinding cylindrical bearing rib is repaired, by the emery wheel after this contact roller for dressing finishing, one-time positioning gets final product two ribs on inside and outside circle raceway of grinding, overcome the quality problems of inside and outside circle width dimensions error duplicating on the lip grinding width, can realize again full-automatic production.
In order to realize the foregoing invention purpose, the present invention by the following technical solutions:
A kind of contact roller for dressing of trimming wheel, its front projection is the H type, the centre of gyration is provided with centre bore, the middle part, outer ring is provided with annular groove, the trim locations of emery wheel external diameter is disposed in groove, the width B of described groove is equal to the width dimensions B of emery wheel after finishing, is equal to equally the raceway width B after the wheel grinding rib.
Further, described contact roller for dressing both ends of the surface outer ring circumferencial direction is provided with chamfering.
After adopting technique scheme, the invention has the beneficial effects as follows:
1, once be installed the finishing after the wheel grinding workpiece on two ribs, overcome width of the workpiece scale error, improved the machining accuracy of rib;
2, the width dimensions B of contact roller for dressing has controlled the polishing width of emery wheel, has namely reached the raceway width and has strictly been controlled;
3, the width dimensions B of contact roller for dressing can design according to raceway width difference, to satisfy the needs of different model bearing edge-fending grinding;
Therefore 4, design because this scheme is based on full-automatic inside and outside circle groove grinder, can realize that workpiece is installed, trimming wheel, grinding work piece, the replacing workpiece is full-automatic produces, thereby realize that lip grinding is full-automatic.

The specific embodiment
In conjunction with Fig. 1 and Fig. 2, the contact roller for dressing 1 of the present embodiment is revolving body, and front projection is the H type, and the centre of gyration is provided with centre bore 4, and outer ring middle part is provided with annular groove 2, and dispose in groove 2 the crushing position 6 of emery wheel external diameter; Contact roller for dressing both ends of the surface outer ring circumferencial direction is provided with chamfering 3.Wherein, the width B of the groove of design suitable width makes the raceway width B after the width dimensions B that repairs rear emery wheel is equal to the wheel grinding rib.
In conjunction with Fig. 3 and Fig. 4, on 3MZK1310 or 3MZK1410 lathe, contact roller for dressing coordinates dresser, and trimming wheel is to control the width dimensions of emery wheel.The width dimensions B of contact roller for dressing can design according to raceway size difference.The emery wheel of utilization after the contact roller for dressing finishing adjusted its grinding position and made it to adapt to 7 places, raceway lip grinding district, and carry out grinding, thereby reach two ribs on workpiece of a grinding, and accurate controlling dimension.
Claims (2)
1. the contact roller for dressing of a trimming wheel, it is characterized in that: the contact roller for dressing front projection is the H type, the centre of gyration is provided with centre bore (4), the middle part, outer ring is provided with annular groove (2), dispose in groove (2) crushing position (6), the width B of described groove (2) is equal to the width dimensions B of emery wheel (5) after finishing, is equal to equally the raceway width B after emery wheel (5) grinding rib.
2. the contact roller for dressing of trimming wheel according to claim 1 is characterized in that: described contact roller for dressing (1) both ends of the surface outer ring circumferencial direction is provided with chamfering (3).
