Description
Technical field
This utility model relates to a kind of bearing measurement instrument, and especially a kind of bearing outer ring seal groove measures slide calliper rule.
Background technology
Seal bearing sealed ring to be typically mounted in the seal groove of outer ring, its dimensional accuracy affects sealing ring and fixes, the gun-type septal fossula rule that existing seal groove dimensional measurement uses Guilin Measuring & Cutting Tools Factory to produce are measured, the rule use of this septal fossula must use slip gauge to adjust to groove footpath approximate size, then measure, require that user has certain alignment technique, and cost is higher.
Utility model content
In order to solve the deficiency that prior art exists, this utility model provides a kind of bearing outer ring groove measuring apparatus of diameter, improves the measurement foot of common calliper, it is simple to measuring the seal groove diameter of seal shaft bearing outer-ring, it is more accurate to measure.Existing common calliper is suitable for cylindrical hole measuring, it is impossible to measure the seal groove size of cone.
A kind of bearing outer ring seal groove diameter measurement slide calliper rule in this utility model, including body and can opposing body's level slide slide assemblies, slide assemblies includes kind of calliper display module, and slide assemblies is provided with the lock-screw for fixing slide assemblies；Body upper part is provided with upper left gauge head, bottom is provided with lower-left gauge head, slide assemblies top is provided with upper right gauge head, bottom is provided with bottom right gauge head, upper left gauge head opening it is provided with outside the gauge head of upper left, upper right gauge head opening it is provided with outside upper right gauge head, upper left gauge head opening and the triangular structure that upper right gauge head opening is drift angle 45 degree, triangle base level, long 2mm, top angle point is away from top 2mm.By this kind of calliper bearing seal ring recess diameter error less than 0.01mm.
The beneficial effects of the utility model: by this kind of calliper bearing seal ring recess diameter error less than 0.01mm, easy to operate, certainty of measurement is high.

Labelling in figure: 1, bearing, 2, bearing outer ring seal groove diameter measurement slide calliper rule, 11, seal groove, 21, slide assemblies, 22, upper right gauge head, 23, upper left gauge head, 24, bottom right gauge head, 25, lower-left gauge head, 26, upper right gauge head opening, 27, upper left gauge head opening.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, but this should not being interpreted as, the scope of above-mentioned theme of the present utility model is only limitted to above-described embodiment.
As it is shown in figure 1, be through-hole structure in the middle of a kind of bearing 1, being provided with seal groove 11 in the middle part of through hole, seal groove 11 depth and width are less than 1.2mm, and seal groove 11 top is provided with the importing conical surface, and importing the conical surface with plane included angle is 45 degree.Existing slide calliper rule are inconvenient to measure the degree of depth of seal groove 11.As Figure 2-3, a kind of bearing outer ring seal groove diameter measurement slide calliper rule, including body and can opposing body's level slide slide assemblies 21, slide assemblies 21 includes that kind of calliper display module, slide assemblies 21 are provided with the lock-screw for fixing slide assemblies 21；Body upper part is provided with upper left gauge head 23, bottom is provided with lower-left gauge head 25, slide assemblies 21 top is provided with upper right gauge head 22, bottom is provided with bottom right gauge head 24, upper left gauge head opening 27 it is provided with outside upper left gauge head 23, upper right gauge head opening 26 it is provided with outside upper right gauge head 22, upper left gauge head opening 27 and the triangular structure that upper right gauge head opening 26 is drift angle 45 degree, triangle base level, long 2mm, top angle point is away from top 2mm.By this kind of calliper bearing seal ring recess diameter error less than 0.01mm.During test, upper left gauge head opening 27 and upper right gauge head opening 26 avoid seal groove top, measure seal groove diameter, convenient use in upper left gauge head 23 and upper right gauge head 22 are stretched into bearing outer ring seal groove, and measuring accuracy is high.
Claims (1)
