Abstract
The invention belongs to the measurement technology and particularly relates to a device for motor brush rack deformation measurement. An electric brush of the motor is installed on the motor brush rack; deformation of the motor brush rack during a motor assembling process directly affects motor performance, so that the deformation of the motor rack needs to be strictly controlled. The invention discloses a device for motor brush rack deformation measurement which is used for measuring a deformation force of the motor brush rack under maximum deformation. The bottom of the deformation measurement device is a holding plate; the inside of the holding plate is a stepped groove structure; a spring is arranged in a groove on the bottom; a measurement plate is arranged on the upper part of the spring; the measurement plate has a radial through hole and an axial through hole; and an annular groove for installing spring sheets is arranged on the radial through hole. The device can accurately measure the automatic measurement of the motor brush rack, and is simple and convenient operation and has a great use value.
Description
Technical field
The invention belongs to measurement technology, be specifically related to the device of the deformation measurement of a kind of motor brush rocker.
Background technology
The brush of motor is arranged on motor brush rocker, and during motor assembling, the deformation of motor brush rocker directly affects motor
Performance, it is therefore desirable to the strict deformation controlling motor brush rocker.The device of a kind of deformation that can accurately measure motor brush rocker can have
Effect ground solves this problem.
Summary of the invention
The technical problem to be solved in the present invention: invent the device of the deformation measurement of a kind of motor brush rocker, completes its deformation force
Measurement.
The device for motor brush rocker deformation measurement of the present invention, for test deformation of motor brush rocker under maximum distortion
Power, this bottom of device is pallet, and this pallet is internal is step groove structure, is spring in bottom groove, and spring top is to measure
Dish, this measurement dish has radial direction through hole and axially extending bore, has the cannelure installing spring leaf on the upside of radial direction through hole；Measure bar
In bar portion, there is relative arcwall face, spring described in lower compression；Force transducer seat is column construction, has and institute in its one end
State the arcwall face of arcwall face coupling, at its other end, force transducer is installed, there is at upper surface the draw-in groove of described spring leaf, should
The other end of spring leaf is fixed on described measurement dish, and described motor brush rocker is arranged in the groove on the upside of described pallet, and
Relative with described force transducer.
It is arranged above cover plate at described measurement dish.It is arranged above hold-down ring at described motor brush rocker.Force transducer with
Force transducer seat is connected together by Wear Characteristics of Epoxy Adhesive in the radial direction through hole being arranged on measurement dish.Described pallet and measurement dish pass through spiral shell
Nail connects.
Manually bar is measured in pressing, described force transducer seat and force transducer along measurement dish radial direction through hole laterally
