Description
Technical field
The present invention relates to a kind of grinding attachment, especially relate to a kind of high-precision bearing lasso plane grinding apparatus.
Background technology
Known, the plane of bearing ring is its most important datum level, it is the basis of subsequent handling processing, the flatness of high-precision bearing lasso, flexibility, parallel error require very high, and the bearing ring flatness of size within φ 400mm, flexibility, parallel error often require within 1 ~ 2 μm; Size often requires within 2 ~ 3 μm at the bearing ring flatness of φ 1000mm, flexibility, parallel error.
Bearing ring belongs to disk-like accessory, multiplex double-ended grinding machine, surface lapping machine machining high-precision bearing ring plane in current industry, but the bearing ring of oversize φ 200mm, and double-ended grinding machine cannot realize high accuracy processing; Within surface lapping machine only can realize φ 280mm, bearing ring high accuracy is processed, but in this size range, for the angular contact bearing having bulge quantity requirement, pairing uses, require one side grinding, lapping machine cannot realize.
Size is more than the bearing ring multiplex surface grinding machine with horizontal spindle grinding plane of more than φ 200mm, often flexural deformation is larger after heat treatment or corase grind stable tempering for bearing ring, lasso flat surface grinding adds man-hour, by the magnetic clamping part of workbench, when magnetizing, absorption of workpieces on the table, produce elastic deformation, demagnetize after having ground one side, product recovers original state, and bending being difficult to is eliminated; The heat moment that grinding produces in addition can reach more than 1000 ~ 1500 DEG C, and part thermal change is uneven, also produces dilatancy thereupon; During grinding part, because part is uneven, usually adopt the methods such as pad pad, paraffine, packing paper to solve, these methods need repeatedly turn-over, and grinding accuracy affects by mat material, is difficult to reach requirement.
Summary of the invention
In order to overcome the deficiency in background technology, the invention discloses a kind of high-precision bearing lasso plane grinding apparatus, solve the problem of high-precision bearing lasso flat surface grinding processing within φ 1000mm, realize the processing of high accuracy, large-size axis parts bearing ring plane machining and the single end face of high-precision bearing lasso.
In order to realize described goal of the invention, the present invention adopts following technical scheme:
A kind of high-precision bearing lasso plane grinding apparatus, comprise supporting seat, support bar, bearing bracket stand and bracing frame, supporting seat is equipped with in the both sides of workbench, supporting seat is provided with several fixing holes, each supporting seat is equipped with bearing bracket stand, each bearing bracket stand is provided with bracing frame, and bracing frame is connected with bearing bracket stand by support bar.
Described supporting seat is at least two.
Described bearing bracket stand is vertically set in the fixing hole of supporting seat.
Support frame as described above is V-structure, and symmetrically vibrational power flow is in bearing ring both sides for bracing frame, and the V-type bottom of bracing frame is connected with support bar, and the V-type opening of bracing frame and the periphery of bearing ring fit.
Owing to have employed technique scheme, the present invention has following beneficial effect:
A kind of high-precision bearing lasso plane grinding apparatus of the present invention, comprise supporting seat, support bar, bearing bracket stand and bracing frame, supporting seat is equipped with by the both sides at workbench, supporting seat is provided with several fixing holes, each supporting seat is equipped with bearing bracket stand, each bearing bracket stand is provided with bracing frame, bracing frame is connected with bearing bracket stand by support bar, solve the problem of high-precision bearing lasso flat surface grinding processing within φ 1000mm, realize the processing of high accuracy, large-size axis parts bearing ring plane machining and the single end face of high-precision bearing lasso; The present invention is practical, and installation and maintenance is all more convenient, operates more convenient, ensure that bearing ring under the turntable that do not magnetize, safe and reliable carry out grinding.

Detailed description of the invention
By explanation the present invention that the following examples can be detailed, disclose object of the present invention and be intended to protect all technological improvements in the scope of the invention.
A kind of high-precision bearing lasso plane grinding apparatus by reference to the accompanying drawings described in 1, comprise supporting seat 7, support bar 1, bearing bracket stand 2 and bracing frame 6, supporting seat 7 is equipped with in the both sides of workbench 4, supporting seat 7 is provided with several fixing holes 8, each supporting seat 7 is equipped with bearing bracket stand 2, each bearing bracket stand 2 is provided with bracing frame 6, and bracing frame 6 is connected with bearing bracket stand 2 by support bar 1; Described supporting seat 7 is at least two; Described bearing bracket stand 2 is vertically set in the fixing hole 8 of supporting seat 7; Support frame as described above 6 is V-structure, and symmetrically vibrational power flow is in bearing ring 5 both sides for bracing frame 6, and the V-type bottom of bracing frame 6 is connected with support bar 1, and the V-type opening of bracing frame 6 and the periphery of bearing ring 5 fit.
Implement a kind of high-precision bearing lasso plane grinding apparatus of the present invention, the novel described a kind of high-precision bearing lasso plane grinding apparatus of first this implementation is arranged on high accuracy surface grinding machine with horizontal spindle in use, when machining high-precision bearing ring, magnetic suction disc does not magnetize, but also rotate with the rotating speed of setting, bearing ring 5 is subject to the constraint of the bracing frame 6 of its both sides, such bearing ring 5 would not have large play, owing to having slight clearance between bracing frame 6 and bearing ring 5, therefore bearing ring 5 is in free state, emery wheel 3 on such high accuracy surface grinding machine with horizontal spindle presses to the end face of bearing ring 5, the rotation of adding workbench 4 can complete the grinding to bearing ring 5.
Part not in the detailed description of the invention is prior art.
