Description
Technical field
The utility model relates to positioning support, relates in particular to the positioning support that a kind of bearing grinding is used.
Background technology
At precision bearing inner surface (internal diameter, outer fissure, outer raceway) and outer surface (septal fossula, interior raceway, external diameter) grinding in, conventionally adopt and be not in the mood for supporting fixture, its chief component element, one is to be with magnetic axial location supporting, another is two radial location supportings, axial location is propped up the part rotation of starting building of breasting and workpiece planarization contact zones, in grinding, there is relative sliding with workpiece, radial location supporting contacts with cylindrical or the interior raceway face of rotational workpieces, it has very strong friction in bearing grinding force, so as positioning support axially and radially, select the crudy of which kind of material to part, comprise circularity, size, ditch shape, percent ripple and surface roughness all have a certain impact.In bearing industry, most widely used is carbide alloy, because of its cost low, easily manufactured, but the wearability of carbide alloy and service life are all not fully up to expectations, in application, the time waste axially and on radial support is very surprising in frequent replacing for flower, due to abrasion, to cause that lasso is processed bad frequency also very high, this is to bore because exist metallic addition in carbide alloy, its coefficient of friction is higher than 0.15, thereby strengthen a frictional resistance of honouring lasso, easily cause the damage of bearing contact surface, thereby impact and destruction machining accuracy, mill processing is used ceramic supporting wearing and tearing very fast, use polycrystalline diamond easily to occur the defects such as shade.
Utility model content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of anti-wear performance good, perfect heat-dissipating, and coupling is reasonable, the positioning support that raising grinding accuracy and the bearing grinding that can increase the service life are used.
The utility model solves the problems of the technologies described above adopted technical scheme: the positioning support that a kind of bearing grinding is used, comprise locating ring, the middle, bottom of described locating ring has through hole, this through hole has inner edge breadth around, in this inner edge breadth, be provided with trip bolt hole, the radially breadth place of described locating ring is embedded with back-up block, and this back-up block is pure polycrystalline diamond back-up block.
Further, described pure polycrystalline diamond back-up block has 8, and this pure polycrystalline diamond back-up block is equidistantly arranged, and the radially breadth of this pure polycrystalline diamond back-up block and locating ring is wide.
Further, described trip bolt hole is 4.
Compared with prior art, the utility model has the advantage of: the utility model is simple in structure, adopt pure polycrystalline diamond back-up block, this pure polycrystalline diamond hardness is high, and coefficient of friction is little, anti-wear performance is good, can effectively improve the service life of supporting, improve the grinding accuracy of product, good reliability, the utility model is reasonable in design, is applicable to large-scale promotion.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model;
Fig. 2 is work schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1-2, the positioning support that a kind of bearing grinding is used, comprise locating ring 1, the middle, bottom of described locating ring 1 has through hole 4, this through hole 4 has inner edge breadth 5 around, on this inner edge breadth 5, there are 4 trip bolt holes, the radially breadth place of described locating ring 1 is embedded with back-up block, this back-up block is pure polycrystalline diamond back-up block 2, this pure polycrystalline diamond back-up block 2 has 8, this pure polycrystalline diamond back-up block 2 is equidistantly arranged, and this pure polycrystalline diamond back-up block 2 is wide with the radially breadth of locating ring 1.
When work, the bottom of locating ring 1 and the laminating of main shaft end face, locating ring 1 is fixedly connected with by trip bolt 3 with main shaft, and the locating ring 1 radially pure polycrystalline diamond back-up block 2 of breadth contacts with workpiece planarization tight fit, and locating ring 1 rotates and drives workpiece rotation simultaneously.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, it will be understood by those of skill in the art that its technical scheme that still can record aforementioned each embodiment modifies, or part technical characterictic is wherein replaced on an equal basis; And these amendments or replacement do not make the essence of appropriate technical solution depart from spirit and the scope of the each embodiment technical scheme of the utility model.
