Description
Technical field
The present invention relates to mechanical component pick-up unit technical field, particularly relate to right alignment universal measurement device.
Background technology
At present along with the development of mechanical field, axial workpiece and cover parts more and more diversified, accuracy requirement is also more and more higher; Current this kind of part all having with cylindrical is the right alignment requirement of benchmark; But due to the variation of axle class, cover parts kind, cause the generation of various measurement mechanism; The axle class of often kind of shape, cover parts all need a kind of coaxality measuring mechanism of specialized designs, which increase production cost, and are unfavorable for the measurement of part in enormous quantities.
Summary of the invention
The object of this invention is to provide a kind of measuring process easy, production cost is low, and is applicable to the right alignment universal measurement device of parts measurement in enormous quantities.
Technical scheme of the present invention is as follows:
Right alignment universal measurement device, comprises mainboard, and mainboard side is provided with groove; There is the depression bar of " L " shape by pinned connection in described groove; One end that described depression bar stretches out groove is provided with wheel shaft, and this wheel shaft is arranged with rubber roller; Described mainboard is provided with a pair installation shaft, and this installation shaft is all arranged with rolling bearing, and two rolling bearings are positioned at below rubber roller; Described depression bar is provided with the first mount pin, and the mainboard immediately below described first mount pin is provided with the second mount pin, is arranged with spring between this second mount pin and first mount pin.
Described wheel shaft is arranged with stop collar.By stop collar, rubber roller is locked on wheel shaft, avoid it to move forward and backward.
Described wheel shaft is arranged with spacing back-up ring.The position of stop collar is fixed by arranging spacing back-up ring.
Described right alignment universal measurement device also comprises lever indicator.By lever indicator and right alignment universal measurement device with the use of.
Described rolling bearing outside surface coating one deck titanium nitride layer.Improve the wearing quality of rolling bearing, extend its serviceable life.
The invention has the beneficial effects as follows: support depression bar and a pair rolling bearing by mainboard; Measured workpiece is compressed between with coordinating of a pair rolling bearing by rubber roller; By first, second mount pin mounting spring, with the upper-lower position making spring can finely tune depression bar, indirectly make measured workpiece firmly be compressed, be convenient to measure; Measured the right alignment of measured workpiece by lever indicator, make right alignment universal measurement measurement device precision of the present invention higher.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.

Embodiment
Shown in Fig. 1-Fig. 2, right alignment universal measurement device, comprises mainboard 1, and mainboard side is provided with groove 2; Be connected with the depression bar 4 of " L " shape by bearing pin 3 in described groove; One end that described depression bar stretches out groove is provided with wheel shaft 5, this wheel shaft is arranged with rubber roller 6; Described mainboard is provided with a pair installation shaft 7, and this installation shaft is all arranged with rolling bearing 8, and two rolling bearings are positioned at below rubber roller; Described depression bar is provided with the first mount pin 9, and the mainboard immediately below described first mount pin is provided with the second mount pin 10, is arranged with spring 11 between this second mount pin and first mount pin; Described right alignment universal measurement device also comprises lever indicator 14; Depression bar and a pair rolling bearing is supported by mainboard; Measured workpiece is compressed between with coordinating of a pair rolling bearing by rubber roller; By first, second mount pin mounting spring, with the upper-lower position making spring can finely tune depression bar, measured workpiece is indirectly made firmly to be compressed; The right alignment of measured workpiece is measured by lever indicator.
During measurement, allow the gauge head of lever indicator touch tested position, rotate rubber roller, then the drive of measured workpiece by rubber roller on a pair miniature bearing rotates, after rotating one week, on lever indicator, the difference of reading maximal and minmal value is exactly tested coaxiality error.
Preferably, described wheel shaft is arranged with stop collar 12.By stop collar, rubber roller is locked on wheel shaft, avoid it to move forward and backward.
Preferably, described wheel shaft is arranged with spacing back-up ring 13.The position of stop collar is fixed by arranging spacing back-up ring.
Preferably, described rolling bearing outside surface coating one deck titanium nitride layer, thus improve the wearing quality of rolling bearing, extend its serviceable life.
Preferably, described titanium nitride layer thickness is 5mm.Titanium nitride layer thickness is 5mm, and abrasion resistant effect is good.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
