Description
Technical field
The utility model belongs to bearing ring secondary process technical field of tools, and what relate generally to is the mill processing device of a kind of thin-walled line face roller bearing.
Background technology
In recent years, along with the continuous growth of thin-wall bearing demand, very large business opportunity is brought to the manufacturing of thin-wall bearing.Because this serial thin-walled conical surface thrust roller bearing lasso part radial dimension section is less than normal, diameter range is ∮ less than 200 millimeters.And bearing ring wall is thin, radial direction is less than 1.2 than coefficient, and lasso both ends of the surface are non-horizontal surface, and inside and outside circular surfaces is again the band angle conical surface, and therefore, technical requirement is tight, required precision is high, brings very large challenge to actual production manufacturing industry.
Utility model content
Therefore the purpose of this utility model produces, and proposes the mill processing device of a kind of thin-walled line face roller bearing.By adopting this device to carry out the inside and outside circular surfaces grinding of thin-walled lasso, not only ensure that the dimensional accuracy that bearing ring grinding is processed and geometric accuracy, and reduce loss due to spoiled work, improve production efficiency.
The utility model realizes the technical scheme that above-mentioned purpose takes: the mill tool for processing of a kind of thin-walled line face roller bearing, comprise mold, pressing plate and bolt, described mold is step conical structure, its frustoconical bevel angle is 45 °, conical surface length is the long 2mm ~ 3mm of bearing ring width comparatively, described pressing plate is the cylinder of band through hole step, and the large outer diameter of step of pressing plate is less than mold cone end diameter 4mm ~ 6mm, and mold and pressing plate are bolted.
Step lower surface on mold excircle described in the utility model is rectangular, upper surface is inclined-plane.
Step lower surface on mold excircle described in the utility model is inclined-plane, upper surface is right angle.
The upper end of pressing plate described in the utility model is ledge structure.
The lower end of pressing plate described in the utility model is ledge structure.
Bolting face >=2mm the gap of mold described in the utility model and pressing plate.
The utility model is by arranging mill processing device, and the cone angle in mold clamping face can be determined according to lasso workpiece binding face cone angle, can use as long as conform to.Therefore, when grinding machining bearing lasso, can accurate controlled working size, realize the processing to thin-wall bearing.The bearing processed not only ensure that the dimensional accuracy that bearing ring grinding is processed and geometric accuracy, and reduces loss due to spoiled work, improves production efficiency, reduces production cost and labour intensity.Have and extend autgmentability, versatility, the features such as applicability is strong, value is large.

Detailed description of the invention
By reference to the accompanying drawings, embodiment of the present utility model is provided as follows:
As shown in Figure 1-2: the present embodiment as described in the mill processing device of thin-walled line face roller bearing comprise mold 1, pressing plate 2 and bolt 4, the described mold 1 for spring bearing lasso is step conical structure, and frustoconical bevel angle is identical with bearing ring inside and outside circle angle, in 45 °, conical surface length is the long 2mm ~ 3mm of bearing ring width comparatively.Wherein: Figure 1 shows that step lower surface on mold 1 excircle at right angles, upper surface is inclined-plane; The step lower surface that Figure 2 shows that on mold 1 excircle is inclined-plane, upper surface is right angle.Described pressing plate 2 shape is the cylinder of band through hole step, and the large outer diameter of step of pressing plate is less than mold cone end diameter 4mm ~ 6mm.Wherein: Figure 1 shows that the upper end of pressing plate 2 is ledge structure; Figure 2 shows that the lower end of pressing plate 2 is ledge structure.Mold 1 and pressing plate 2 are bolted.
When processing ferrule outer surface, thin-walled lasso workpiece 3 being placed on fixture clamping fixture 1 outer surface, lasso inner surface being overlapped with the outer poppet surface of mold 1 and contacts.Be close to ring face with pressing plate 2 again and use bolt 3 fastening.Single unit system is placed on cylindrical grinder workpiece spindle disk, and mold 1 end face and lathe disk face are fitted, and mold 1 outer cylinder surface is supporting surface, fits with the v-shaped bearing face adjustment be fixed on lathe support saddle frame.Drive single unit system to rotate by disk, emery wheel carries out the processing of outer cone surfacing to lasso after revising.
Described in detail for installation diagram 1 below: thin-wall bearing ferrule grinding utility unit is made up of mold 1, pressing plate 2 and bolt 4.The large end face of mold 1 is locating surface, and outer cylinder surface is bearing-surface, and little round platform is the conical surface, and its cone angle 45 ° conforms to thin-wall bearing ferrule aperture cone angle and forms clamping face.Pressing plate 2 shape is the cylinder of band through hole step, with mold 1 with the use of.After lasso workpiece 3 taper hole puts into mold 1 clamping face, pressing plate 2 outer end cylinder fillet surface withstands on thin-wall bearing ring face, finally uses bolt 4 fastening.In order to firm fixing lasso workpiece 3, mold 1 and the bolting face >=2mm gap of pressing plate 2, leave suitable pre-compact space for clipping lasso workpiece 3.The quantity of bolt can according to bearing ring pore size reasonable selection, and to meet jail, the uniform force of workpiece clamp, deflection is little is good.
If during processing thin-walled bearing ring inner surface, can refer to Fig. 2 schematic diagram, clamping form is similar to Fig. 1, and difference is to select suitable internal grinder equipment to carry out grinding internal surface processing.
After mold 1 and each part of pressing plate 2 are the processing of car system, integral quenching.Quenching hardness 58 ~ 62HRC, will carry out 150 DEG C of stable process after preliminary grinding, constant temperature 5 hours, allows internal stress fully discharge, then carries out fine grinding processing to mold 1 critical surfaces.Ensure that locating surface that utility unit is correlated with reaches the technical requirement of regulation.Clip simultaneously workpiece make mold and pressing plate be heated or stressed after not yielding so that the grinding of the outer poppet surface of bearing ring (or interior poppet surface).
