Abstract
The utility model discloses a kind of support wheel structure for cold grinding, comprise two support wheels (1) and two supporting seats (2), each support wheel (1) is installed on a supporting seat (2), each support wheel (1) is equipped with the guide roller that prevents workpiece (3) and support wheel (1) direct friction, the inner side of each supporting seat (2) is equipped with a groove (4), and each guide roller is all a tight fit in a groove (4).This support wheel structure can be avoided workpiece and support wheel direct friction and wear and tear.
Description
Technical field
The utility model relates to a kind of cold grinding for bearing ring processing, is specifically a kind of support wheel structure for cold grinding.
Background technology
Cold grinding is a kind of equipment of machining bearing lasso.Add man-hour, drive muller to rotate by mair motor, drive the support wheel parts be arranged on master slider to be moved to the left simultaneously, promote core rod and press to workpiece to carry out spreading, such that workpiece is thinning, diameter swell.The die draft that muller and core rod form determines the cross sectional shape of workpiece.The cold grinding of said structure has the following disadvantages in the process of reality: workpiece is meeting and support wheel direct friction in process, thus cause the wearing and tearing of workpiece and support wheel, so not only can reduce the service life of support wheel, increase processing cost, and workpiece damage can be caused, make the yield rate of workpiece lower.Therefore, for these reasons, urgently need a kind of support wheel structure for cold grinding, this support wheel structure can be avoided workpiece and support wheel direct friction and wear and tear, to solve the problem.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of support wheel structure for cold grinding, and this support wheel structure can be avoided workpiece and support wheel direct friction and wear and tear.
The technical solution of the utility model is, a kind of support wheel structure for cold grinding is provided, comprise two support wheels and two supporting seats, each support wheel is installed on a supporting seat, each support wheel is equipped with the guide roller that prevents workpiece and support wheel direct friction, the inner side of each supporting seat is equipped with a groove, and each guide roller is all a tight fit in a groove.
Described guide roller comprises a rotating shaft, multiple bearing and multiple needle bearing; The left and right sides of each needle bearing is equipped with a bearing; Described multiple bearings, multiple needle bearing are all socketed in rotating shaft.
After adopting above structure, the utility model compared with prior art, has the following advantages:
The utility model support wheel structure is equipped with the guide roller that prevents workpiece and support wheel direct friction on the medial surface of two support wheels, what first touch when workpiece produces deflection distortion like this is guide roller, workpiece drives guide roller original place to rotate, and is in pure rolling friction state.Workpiece is limited in the scope folded by two guide rollers all the time, can not produce contact with support wheel, thus ensures that the asymmetric part of rolling is smooth.So not only can improve the service life of support wheel, reduce processing cost, and workpiece damage can not be caused, make the yield rate of workpiece higher.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of support wheel structure for cold grinding of the utility model, comprise two support wheels 1 and two supporting seats 2, each support wheel 1 is installed on a supporting seat 2, each support wheel 1 is equipped with the guide roller that prevents workpiece 3 and support wheel 1 direct friction, the inner side of each supporting seat 2 is equipped with a groove 4, and each guide roller is all a tight fit in a groove 4.
Described guide roller comprises a rotating shaft 5, multiple bearing 6 and multiple needle bearing 7; The left and right sides of each needle bearing 7 is equipped with a bearing 6; Described multiple bearings 6, multiple needle bearing 7 are all socketed in rotating shaft 5.In the present embodiment, four needle bearings 7 and five bearings 6 are had.
Add man-hour, drive muller 9 to rotate by mair motor 8, drive the support wheel structure be arranged on master slider 10 to be moved to the left simultaneously, promote core rod 11 and press to workpiece 3 to carry out spreading, make workpiece 3 wall thickness reduction, diameter swell.
Below only just most preferred embodiment of the present utility model is described, but can not be interpreted as it is limitations on claims.The utility model is not limited only to above embodiment, and its concrete structure allows to change.In every case the various change done in the protection domain of the utility model independent claims is all in protection domain of the present utility model.
