A grinding wheel trimming machine for polishing oval channels of an inner ring and an outer ring of a ball bearing comprises a base and a rotating part, wherein the rotating part comprises a rotary seat and a diamond pen holder equipped with a diamond pen for trimming a grinding wheel; a rotary connecting end of the rotary seat is rotationally arranged on the base; the diamond pen holder is rotationally arranged at a work end of the rotary seat through a diamond pen rotating shaft; and the diamond pen rotating shaft and the central line of a to-be-processed grinding wheel form an included angle ranging from 45 degrees to 90 degrees. The grinding wheel trimming machine is simple in structure, high in processing efficiency and simple and convenient to operate; meanwhile, a processed grinding wheel can be used for directly polishing the oval channels of the inner ring and the outer ring of the ball bearing and can be contacted with the bearing at three or four points to be stressed, and the grinding wheel is formed through one-time trimming, so that displacement H of the diamond pen or the grinding wheel doesn't exist, the process from no load to load or from load to no load of the diamond pen doesn't exist, and the shape and the accuracy are more easily guaranteed.
Description
Technical field
The utility model relates to a kind of wheel dresser, especially relates to the emery wheel finishing machine of the oval raceway groove of the inside and outside circle of a kind of ball bearing of polishing.
Background technology
In the grinding of ball bearing ring channel, be generally that requirement is circular the grinding of raceway groove circular arc, to coordinate with steel ball.But in actual use, the probability that steel ball and ring raceways fit like a glove is very little, generally, when steel ball size is less than raceway diameter, steel ball just contacts with the bottom A point of outer collar raceway groove, contact with the bottom B point of inside race raceway groove, when steel ball size is greater than raceway diameter, steel ball just contacts with the C of both sides of edges portion, D, E, the F point of inner and outer ring raceway groove.So the ratio problem of inquiring into steel ball size and raceway diameter is also a focal issue of current bearing industry.In order to make steel ball better with coordinating of raceway groove, on market, occurred that ring raceways grinding be " peach-shaped ditch " shape, then 3 points that coordinate with steel ball, four spot contact bearings.Ring raceways grinding, being " peach-shaped ditch " shape, generally, is axial displacement and the diamond pen rotation combination that utilizes emery wheel, crushing is become to " peach-shaped ditch " shape, then uses the emery wheel crush grinding ring raceways of moulding.
1, for guarantee to repair out the unification of grinding wheel shape at every turn, each shift length H of diamond pen or emery wheel is had to certain requirement.
2, diamond pen at every turn to the process of crushing in, all exist and be less than time of 1/2 at trimming wheel, be greater than time of 1/2 in dry run, diamond pen all exist one by zero load to load, or by loading to unloaded process, add finishing at twice, so the shape of trimming wheel and precision are all not easy to guarantee, and technique is comparatively complicated.
3, " peach-shaped ditch " top is wedge angle transition, easily produces stress and concentrates cracking, and axle bearing load is had to considerable influence.
4, emery wheel is twice finishing, and non-cutting time is long, and the output in the lathe unit interval is had to considerable influence.The particularly lasso higher to required precision, affects larger.
Utility model content
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, the emery wheel finishing machine of the oval raceway groove of the inside and outside circle of a kind of ball bearing of polishing is provided, not only solve existing finishing machine complex structure and do not allowed easy-operating problem, adopted this lathe can make 3 of the oval raceway grooves of the inside and outside circle of ball bearing or four spot contact bearings of finishing gear polishing out stressed simultaneously.
The utility model is the deficiency solving the problems of the technologies described above, and the technical scheme adopting is:
The emery wheel finishing machine of the oval raceway groove of the inside and outside circle of a kind of ball bearing of polishing, comprise a base and a rotary part, described rotary part comprises that rotating seat and one are provided with the Buddha's warrior attendant penholder of trimming wheel diamond pen, the end that is rotatably connected of rotating seat rotates and is arranged on base, Buddha's warrior attendant penholder is rotated and is arranged on the working end of rotating seat by diamond pen rotating shaft, and described Buddha's warrior attendant penholder rotating shaft and the center line of emery wheel to be processed are 45-90 ° of angle.
Described base inside is also provided with one for preventing the slip away gland of base of rotating seat.
Described Buddha's warrior attendant penholder rotating shaft and the center line of emery wheel to be processed are 80-90 ° of angle.
The beneficial effects of the utility model are: the utility model is simple in structure, working (machining) efficiency is high, simple to operation, the emery wheel simultaneously processing can for the direct polishing oval raceway groove of the inside and outside circle of ball bearing and make its 3 or four spot contact bearings stressed, and emery wheel is once to repair moulding, does not have the displacement H of diamond pen or emery wheel, do not exist diamond pen by zero load to load, or by loading to unloaded process, shape and precision more easily guarantee.

Fig. 1 is front view of the present utility model.
Fig. 2 is the left view in Fig. 1.
Graphical indicia: 1, diamond pen; 2, emery wheel to be processed; 3, Buddha's warrior attendant penholder; 4, rotating seat; 5, diamond pen rotating shaft; 6, gland; 7, base; 8, diamond pen rotary track; 9, emery wheel outer rim; 10, diamond pen centre of gyration line.
The specific embodiment
Shown in figure, the specific embodiment is as follows:
In a kind of polishing ball bearing, the emery wheel finishing machine of the oval raceway groove in outer ring, comprise a base 7 and a rotary part, described rotary part comprises that rotating seat 4 and one are provided with the Buddha's warrior attendant penholder 3 of trimming wheel diamond pen 1, the end 402 that is rotatably connected of rotating seat 4 rotates and is arranged on base 7, Buddha's warrior attendant penholder 3 is rotated and is arranged on the working end 401 of rotating seat 4 by diamond pen rotating shaft 5, described Buddha's warrior attendant penholder rotating shaft 5 is 45-90 ° of angle with the center line of emery wheel 2 to be processed, so just guaranteed the diamond pen of trimming wheel, its rotational trajectory becomes 0-45 ° of angle with the centre of gyration line of emery wheel.
Described base 7 inside are also provided with one for preventing the slip away gland 6 of base 7 of rotating seat 4, and gland 6 is bolted on the end that is rotatably connected on rotating seat 4, and two edges of gland 6 are fastened on the inwall of base 7.
Described Buddha's warrior attendant penholder rotating shaft 5 is 80-90 ° of angle with the center line of emery wheel 2 to be processed, has so just guaranteed the diamond pen of trimming wheel, and its rotational trajectory becomes 0-10 ° of angle with the centre of gyration line of emery wheel.
Adopting this finishing machine to make emery wheel is once to repair moulding, does not have the displacement H of diamond pen or emery wheel, do not exist diamond pen by zero load to load, or by loading to unloaded process, shape and precision more easily guarantee.Configuration top is arc transition, and stress is not easy to concentrate, not easy to crack, less on the impact of axle bearing load.Simple in structure, easy to adjust.Non-cutting time is short, and efficiency is higher.Thereby all adverse consequences that lasso brings have been avoided cutting in subsequent process.
The technical scheme that the utility model is cited and embodiment are not restrictions, in the cited technical scheme of the utility model and embodiment is equal to or effect same approach is all protected at the utility model scope.
