The utility model provides an encoder mounting structure for electricity main shaft, the encoder reads data accurately, and the feedback is sensitive, and the location is accurate, and stability is good, and installation accuracy and machining precision are high, installs and removes the convenience.
Description
Technical Field
The utility model relates to a machinery processing technology field specifically is an encoder mounting structure for electricity main shaft.
Background
In the process of machining the main shaft, a main shaft cutter needs to be positioned, indexed and tapped, and the main shaft needs to be provided with an encoder. The encoder is a sensor for detecting angle, position, speed and acceleration, and is a device for compiling and converting angular displacement or linear displacement of mechanical rotation into an electric signal form for communication, transmission and storage, and is a precision measurement device closely combined mechanically and electronically. In the process of machining the main shaft, a main shaft cutter needs to be positioned, indexed and tapped, and the main shaft is particularly required to be provided with an encoder.
The encoder consists of an encoder gear disc and a magnetic induction reading head matched with the encoder gear disc. The encoder toothed disc is installed on the rotating main shaft, and the magnetic induction reading head is installed in the outside top of encoder toothed disc, and the clearance between magnetic induction reading head and the encoder toothed disc is 0.1 to 0.3 mm.
The existing encoder gear disc is generally tightly pressed and fastened by nuts, and the perpendicularity of thread lines and end faces of fastening nuts is difficult to guarantee, so that the encoder gear disc is inclined, the encoder reads inaccurate data, the feedback is not correct, the positioning is inaccurate, the high speed is unstable, and the processing precision is poor.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned weak point to a encoder mounting structure for electricity main shaft is provided, the encoder reads data accurate, and the feedback is sensitive, and the location is accurate, and stability is good, and installation accuracy and machining precision are high, installs and removes the convenience.
The technical scheme of the utility model is that: the utility model provides an encoder mounting structure for electricity main shaft, includes the step shaft, characterized by: the step shaft is equipped with big diameter section, little diameter section, step, and bearing lock nut is installed to the big diameter section tip of step shaft, and the encoder toothed disc is installed to the little diameter section of step shaft, and the encoder toothed disc is pressed on the step of step shaft, through the screw fastening between encoder toothed disc and the bearing lock nut.
The utility model has the advantages that: the utility model provides an encoder mounting structure for electricity main shaft, the encoder reads data accurately, and the feedback is sensitive, and the location is accurate, and stability is good, and installation accuracy and machining precision are high, installs and removes the convenience.
Drawings
