Abstract
The utility model provides a dabber device convenient to accommodate motor encoder installation error, belongs to motor technical field for solve the not high problem of encoder dabber installation accuracy of motor shaft tip, its technical scheme is, it includes dabber body, fastening bolt and adjusting bolt, the dabber body is equipped with the ring flange with the one end of motor shaft butt joint, the ring flange passes through fastening bolt and is connected with the terminal surface of motor shaft, adjusting bolt sets up threely, and the top is on the terminal surface of motor shaft for the threaded hole on the ring flange of their screw in dabber bodies, and three adjusting bolt follows the circumference evenly distributed coaxial with the dabber body. The utility model discloses the angle of utilizing three adjusting bolt to adjust the dabber body, it has higher axiality with the motor shaft to make it, recycles fastening bolt and fixes dabber body and motor shaft together to improve the installation accuracy of dabber body, guaranteed the normal operating of encoder and motor.
Description
Technical field
The utility model relates to a kind of mandrel device for mounted motor encoder, belongs to technical field of motors.
Background technology
Motor encoder is mounted in the transducer that motor shaft end is used for measuring position of magnetic pole and motor corner and rotating speed.At present, code segment device no longer adopts traditional shaft coupling mounting means, but by encoder endoporus, encoder is directly sleeved on the mandrel of motor shaft end, this just proposes very high requirement (radial installation accuracy reach 0.05mm within) to the manufacture of mandrel and installation accuracy.And in fact, the radial installation accuracy of encoder mandrel often cannot meet instructions for use during Motor Production Test, cause motor in use often to occur false alarm phenomenon, have a strong impact on normally carrying out of production.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of mandrel device being convenient to regulate motor encoder alignment error, to prevent motor from occurring false alarm phenomenon because encoder mandrel installation accuracy is low, ensures that motor normally runs.
Problem described in the utility model realizes with following technical proposals:
A kind of mandrel device being convenient to adjustment motor encoder alignment error, formation comprises mandrel body, fastening bolt and adjustment bolt, one end that described mandrel body docks with motor shaft is provided with ring flange, and described ring flange is connected with the end face of motor shaft by fastening bolt; Described adjustment bolt arranges three, and their to screw in the screwed hole on the ring flange of mandrel body and withstand on the end face of motor shaft, and three adjustment bolts distribute along the even circumferentials coaxial with mandrel body.
Above-mentionedly be convenient to the mandrel device regulating motor encoder alignment error, the quantity of described fastening bolt is three, three adjustment bolts and three fastening bolts equidistantly spaced apart along the same circumference coaxial with mandrel body.
The utility model utilizes three angles adjusting bolt adjustment mandrel body, make it there is higher axiality with motor shaft, mandrel body and motor shaft are fixed together by recycling fastening bolt, thus improve the installation accuracy of mandrel body, ensure that the normal operation of encoder and motor.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
In figure, mark is as follows: 1, mandrel body, and 2, adjust bolt, 3, fastening bolt.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises mandrel body 1, adjustment bolt 2 and fastening bolt 3.In fig. 2, six bolts are circumferentially being uniformly distributed, comprising three adjustment bolts 2 and three fastening bolts 3 with coaxial same of mandrel body 1.Three adjustment bolts 2 are circumferentially being uniformly distributed, and three fastening bolts 3 are also circumferentially uniformly distributed at this, and two kinds of bolt spacings are arranged.
The ring flange of mandrel body 1 end is fixed on motor shaft tail end by three fastening bolts 3, and three adjustment bolts 2 screw in the screwed hole of mandrel body 1 end flange dish, and the end of adjustment bolt 2 withstands on the end face of motor shaft.Obviously, after unclamping fastening bolt 3, each adjustment bolt 2 is regulated to stretch out the length of ring flange end face, the angle between the axis of mandrel body 1 and motor shaft axis can be changed, adjusted coordinating of bolt 2 with adjustment by fastening bolt 3, just can effectively reduce the circular runout of mandrel body 1, by the installation accuracy control of adjustment mandrel 1 in allowed limits (radial installation accuracy reach 0.05mm within), keep its stability in use.
