Description
Technical field
The invention belongs to bearing machining detection technique fields, are related to a kind of contact angle measurement, specifically a kind of micro-
Type angular contact ball bearing contact angle measurement mainly applies to the detection of miniature angular contact ball bearing contact angle.
Background technique
The instrument sold currently on the market is mostly the measurement for being applicable in conventional angular contact bearing contact angle, and expensive, for
Suitable for the instrument of the miniature angular contact ball bearing assembling process Contact-angle measurement of factory, there is presently no angular contact ball bearing is general
Production process be all to be assembled with the trap size calculated, i.e., guarantee assembly contact angle indirectly, but for miniature corner connection
Touch ball bearing, the standards such as ditch diameter size are difficult to measure, contact angle depend merely on theoretical value can not strict guarantee, the measurement of contact angle
It is just particularly important with being mutually authenticated for cooperation.Therefore the characteristics of being directed to production plant's polytypic, scene is facilitated to use, it needs to set
Count a kind of novel convenient and fast contact angle measurement.
Summary of the invention
It is an object of the invention to solve the problems, such as that miniature angular contact ball bearing contact angle production scene measures, and reduce life
Cost is produced, a kind of apparatus for measuring contact angle of angular contact bearing is provided, it is easy to use, it is low in cost, it is factory's development and production
Polytypic angular contact ball bearing provides precision guarantee.
According to the technical solution that apparatus of the present invention provide, the contact angle measurement, including mounting bracket, bearing block, core
Axis, load briquetting and scale, the mounting bracket include the pedestal and upper plate being connected by pillar, and the bearing block is mounted on
The middle part of plate, the mandrel are mounted in bearing block, and the upper end of mandrel stretches out bearing block and is equipped with load briquetting, the load pressure
Block is equipped with scale, and the lower end of scale is equipped with the pointer portion for being parallel to upper plate.
Further, the upper plate is equipped with angle scale.
Further, upper plate is stretched out in the upper end of the bearing block, and the angle scale is set on bearing block.
Further, the lower end of the mandrel is equipped with clump weight.
Further, the scale is connected by connecting rod with load briquetting, and connecting rod is matched with load briquetting by screw thread
It closes.
The beneficial effects of the present invention are: structure is simple, occupies little space；It is convenient to replace model, adjustment is quick；Component knot
Structure is simple, and processing cost is low；The detection of contact angle in miniature angular contact ball bearing production process can be achieved.
Detailed description of the invention

Specific embodiment
The invention will be further described with attached drawing combined with specific embodiments below.
It is as shown in the figure: contact angle measurement, including mounting bracket, bearing block 9, mandrel 8, load briquetting 7 and scale 5.Its
In, mounting bracket includes pedestal 1 and upper plate 3, is connected between pedestal 1 and the quadrangle of upper plate 3 by pillar 2.Bearing block 9 passes through
Screw is mounted on the middle part of upper plate 3, and mandrel 8 is mounted in bearing block 9, and the upper end of mandrel 8 stretches out bearing block 9 and is equipped with load pressure
Block 7, load briquetting 7 are equipped with scale 5, and the lower end of scale 5 is equipped with the pointer portion for being parallel to upper plate 3.
It covers in use, part 4 to be measured is put on bearing block 9 in the upper end of mandrel 8, the lower end of load briquetting 7 is pressed in be measured
On the inner ring of part 4, determines initial position and mark that (inner ring position can pass through note by 5 position mark of scale, retainer
Number pen label), temperature of inner ring during rotation retainer plate number stops, and the differential seat angle for obtaining inner ring and retainer is contact angle, and principle is benefit
Measurement is realized in the speed difference of rotary course with bearing internal external circle, retainer.
Specifically, upper plate 3 is equipped with angle scale, convenient for rotating the reading of angle.Upper plate 3, angle are stretched out in the upper end of bearing block 9
Scale is set in bearing block 9 and stretches out on the part of upper plate 3, easy for assemble or unload, without fixing.Scale 5 is by connecting rod 6 and bears
Lotus briquetting 7 is connected, and connecting rod 6 passes through with load briquetting 7 to be threadedly engaged, easy to disassemble.
The lower end of mandrel 8 stretches out bearing block 9 and is equipped with clump weight, acts on 4 inner ring of part to be measured for great load briquetting 7
On pressing force, clump weight is replaceable, different workpieces situation is simulated by the clump weight of different weight, as stability, bearing make
Pretightning force size measures more accurate.
The present invention utilizes the principle of angular contact bearing Internal and external cycle, the speed difference of retainer during operation, and inner ring is motionless
(or outer ring is motionless), rolling bearing outer ring (inner ring) obtain the angle of outer ring (inner ring) and retainer after rotating a fixing turn
Difference is the actual contact angle, and structure is simple, easy to use, and bearing block 9, mandrel 8, load briquetting 7 and 5 members of scale can be more
Cost can be greatlyd save for production enterprise for realizing polytypic product Contact-angle measurement by changing (size etc.).
