Abstract

The utility model relates to a dynamic balance finishing machine capable of automatically positioning the rotor angle of a direct current motor, which is composed of a bracket assembly, a clamping division component, a feeding milling component, a base, a carrying cabinet and an operation button. The finishing machine is characterized in that the inner side of the bracket assembly is provided with an infrared diaphragm sensor, and the center line of the probe of the infrared diaphragm sensor and a zero line on the clamping division component are coaxial and pass through the shaft center of a rotor. The utility model has the advantages of speediness, accuracy and high work efficiency.

Description

The DC motor rotor angle is the dynamic balancing straightener of location automatically

Technical field:

The utility model relates to a kind of DC motor rotor angle dynamic balancing straightener of location automatically, can be used for DC motor rotor dynamic balancing finishing processing, belongs to DC motor rotor correction processing technique field.

Background technology:

DC motor rotor in the course of processing since coiling after, the quality of rotor is unbalanced, produce vibration when making the rotor high-speed running, must detect amount of unbalance through dynamic balancer, further mill away amount of unbalance again, run up thereby satisfy the machine operation timeliness through the dynamic balancing straightener.Common way is: amount of unbalance is converted the left side of rotor core after the computer programs process of dynamic balancer, right two ends, mark the quality of angle and this milling, its angle is to rise with the zero degree that marks out on the rotor phase changer to begin to calculate, by manually being trimmed on the carriage assembly that rotor is put into the dynamic balancing straightener, make the zero degree start line on the rotor phase changer aim at the zero line that clamps on the indexing part, the angle calculated to computer of rotor begins milling then, because people's the collimation error, make the zero degree start line on the rotor phase changer can not definitely aim at the zero line that clamps on the indexing part, thereby the relative error of causing, the existence of this error descends the balance quality of rotor that was corrected, the vibration of rotor can't be eradicated, the speed of manual-alignment zero line is slow simultaneously, and work efficiency is not high yet.

Summary of the invention:

The purpose of this utility model is exactly the dynamic balancing straightener of the automatic location of DC motor rotor angle that invention is a kind of fast, accurate, work efficiency is high.

For realizing above purpose, the technical solution of the utility model provides a kind of DC motor rotor angle dynamic balancing straightener of location automatically, it is made up of carriage assembly, clamping indexing part, feeding milling parts, base, carrying cabinet, operation button, it is characterized in that, be equipped with an infrared light coil sensor in the inboard of carriage assembly, the center line of infrared light coil sensor probe and the coaxial and mistake rotor axis of zero line that clamps on the indexing part.

Be equipped with on the dynamic balancing straightener of photoelectric sensor, to be corrected on the carriage assembly that rotor is put into the dynamic balancing straightener at random, start the operation button, clamp the indexing part clamping and be trimmed rotor, be trimmed the rotor entry into service, after photoelectric sensor detects zero degree start line on the rotor phase changer, running stops, and suspends 0.2 second, has promptly located automatically, rotate to the angle that computer calculates then and begin milling, go the quality of this unnecessary milling of the left and right two ends of rotor up to milling.

The utility model has the advantages that fast, accurately, work efficiency is high.

Description of drawings:

Fig. 1 is the DC motor rotor angle dynamic balancing straightener front view of location automatically;

Fig. 2 is the DC motor rotor angle dynamic balancing straightener left view of location automatically;

Fig. 3 is the DC motor rotor angle dynamic balancing straightener vertical view of location automatically;

Embodiment:

As shown in Figure 1 and Figure 2, be the dynamic balancing finishing machine that the DC motor rotor angle is located automatically, it is made up of carriage assembly 1, photoelectric sensor 2, clamping indexing part 3, feeding milling parts 4, base 5, carrying cabinet 6, operation button 7.

Screw means is used with photoelectric sensor 2 in inboard at carriage assembly 1, makes the center line of transducer 2 probes perpendicular with the zero line that clamps on the indexing part 3.

Be trimmed on the carriage assembly 1 that rotor 8 can be put into the dynamic balancing finishing machine at random, to wait to repair its amount of unbalance.
