Abstract

The utility model relates to a runout detector of an electric motor extension shaft radial which belongs to the electric motor detecting fixture technical field, comprising a soleplate which is provided with a locating block, wherein, the upper part of the locating block is provided with a V-shaped groove, one side of the V-shaped groove is provided with a hold-down mechanism which is provided with at least one compressing block on the upper part of the V-shaped groove, the lateral surface on one end of the V-shaped groove is provided with a clock gauge, a gauge head of the clock gauge is pointed at the V-shaped groove. The utility model with simple structure can conveniently detect the radial runout of the electric motor extension shaft and solve the problems of the prior art that a device specially for detecting the radial runout of the electric motor extension shaft lacks and the detection is inconvenient.

Description

Motor Shaft diameter run-out detector

Technical field

The utility model relates to a kind of Motor Shaft diameter run-out detector, belongs to the technical field that motor detects frock.

Technical background

The big young pathbreaker of the diameter run-out of Motor Shaft directly has influence on the noise in the motor operation course, and cooperating between Motor Shaft and load or the reducer casing.Do not seen in the prior art to be specifically designed to the pick-up unit that detects the Motor Shaft diameter run-out, so detect existence inconvenience for the diameter run-out of Motor Shaft.

Summary of the invention

It is a kind of simple in structure that the utility model purpose is to provide, the Motor Shaft diameter run-out detector that can be easily the diameter run-out of Motor Shaft be detected, the problems such as the device that detects the Motor Shaft diameter run-out, detection inconvenience that are not specifically designed to that prior art exists have been solved.

Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises base plate, locating piece on the described base plate, locating piece top is provided with the V-arrangement fluting, the V-arrangement side of slotting is provided with hold-down mechanism, described compressing structure is provided with at least one compact heap that is positioned at V-arrangement fluting top, the slot side of an end of described V-arrangement is provided with clock gauge, and the gauge outfit of described clock gauge is pointed to the V-arrangement fluting.During detection, to treat that measured motor is arranged in the V-arrangement fluting of locating piece, and make the shaft for the treatment of measured motor that one end of clock gauge is set corresponding to the V-arrangement fluting, thereby acting on, the compact heap then by hold-down mechanism treats that the measured motor upper surface will treat that measured motor is fixed, gauge outfit with clock gauge contacts with the circumferential surface of Motor Shaft to be measured again, restart motor, can read the diameter run-out for the treatment of measured motor easily by clock gauge, whether satisfy error requirements with the diameter run-out of judging Motor Shaft to be measured, comparatively convenient.

As preferably, described hold-down mechanism comprises a support of fixing with base plate, described compact heap is arranged at fork one end, the other end of fork is affixed with the acute angle of the connecting plate of a rectangular triangular structure and overlap with the right-angle side of connecting plate, another acute angle of connecting plate and the upper end hinged inside of support, one end of the right angle of described connecting plate and control lever is hinged, and an end of the middle part of described control lever and support bar is hinged, and the other end of described support bar and the outside, the upper end of support are hinged.Free end by the operating operation bar can be operated moving up and down of compact heap easily, to realize treating compressing or unclamping of measured motor.Wherein, the structure that hold-down mechanism also can adopt cylinder to compress can also adopt feed screw nut's structure.

As preferably, described compact heap is that elastomeric material is made.Wherein, compact heap adopts elastomeric material to make can to increase compact heap on the one hand and treats friction force between the measured motor surface, also can avoid compact heap to treat the damage on measured motor surface on the other hand.

As preferably, be connected by screw retention between described locating piece and the base plate.

Therefore, the utlity model has simple in structurely, can be easily the diameter run-out of Motor Shaft such as be detected at characteristics.
