Description

A kind of complete cross-section thin-wall bearing inner ring pulsation measurement device
Technical field
The utility model is related in a kind of measuring device of complete bearing more particularly to a kind of complete cross-section thin-wall bearing Enclose pulsation measurement device.
Background technology
Cross-section thin-wall bearing is widely used in intelligent robot and automobile industry because its is light, thin, small, axial to jump Dynamic and circular runout seriously affects the stationarity of the precision and automobile of robot motion completion.It was measured in plain bearing finished product Cheng Zhong usually supports the outer ring of bearing with the platform with guider or measuring instrument, then applies certain load to inner ring, Inner ring rotation is driven, to measure axial runout and the circular runout of inner ring.And cross-section thin-wall bearing since its lasso is light and It is thin, and end face only has several millimeters, with the method for the platform with guider, measurement difficulty is big, and a people can not complete independently Operation, if carried out with measuring instrument, the load of application easily makes bearing deform again, and the result not only measured is inaccurate, It is also easy to that bearing is caused to damage, to influence the production efficiency of entire enterprise, therefore is badly in need of a kind of new measuring device to solve Certainly existing problem.
Utility model content
The purpose of this utility model is to propose a kind of complete cross-section thin-wall bearing inner ring pulsation measurement device, for eliminating Bearing deforms in measurement process, improves the accuracy of measurement.
Following technical scheme can be used to realize in the purpose of this utility model:A kind of complete cross-section thin-wall bearing inner ring jump Dynamic measuring device, including:Platform, locating shaft, bearing support block, fastening bolt, tommyhead bolt, pressing plate and measuring mechanism, it is described Side was equipped with the T-slot at center above platform, and the other side is symmetrical with T-slot and sets that there are two threaded holes;The locating shaft is total Two, one end is equipped with fixing axle, and fixing axle is equipped with external screw thread, is separately mounted in two threaded holes above platform, two The other end of locating shaft is equipped with tapped blind hole;The bearing support block is the consistent ladder-like annular round platform of outer diameter, outside Diameter is identical as the outer diameter of measured bearing, and outer wall is close to two locating shafts, is positioned over above platform, and measured bearing is placed on bearing branch It supports on seat;The fastening bolt is mounted in the tapped blind hole of locating shaft, is coordinated with pressing plate, by measured bearing and bearing support Seat is fixed on platform jointly;The tommyhead bolt is placed in the T-slot of platform, is coordinated with pressing plate, by measured bearing and bearing The another side of support base is fixed on platform;The measuring mechanism is axial amesdial and radial amesdial, difference respective shaft The axial runout and circular runout for holding inner ring measure.
For the locating shaft external cylindrical surface perpendicular to platform, external cylindrical surface height is higher than bearing support block, and is no more than Measured bearing upper surface.
Bearing support block upper part cross-sectional width is equal to the outer ring wall thickness of measured bearing.
The utility model has the beneficial effects that:Locating shaft and T-slot are used, it is simple in structure, it is easily installed, is not only convenient for The correction of the location of workpiece in measurement process, applies also for the bearing measuring of different-diameter;It is fastened using pressing plate, strength is easy the palm Control, can effectively avoid cross-section thin-wall bearing and deform, measurement result is more acurrate, a people can complete independently measure operation, Greatly improve the production efficiency of enterprise.
