The frequency converting device of the precision steel ball crusher spindle system comprises a frequency converter, a motor, a speed change mechanism and a spindle, wherein the frequency converter is connected with an input end of the motor, an output end of the motor is connected with an input end of the speed change mechanism, an output end of the speed change mechanism is connected with the spindle, the frequency converter is a 30KW frequency converter, and the motor is a 24KW three-speed main motor. The frequency converting device of the precision steel ball crusher spindle system has the advantages that a modified spindle is stable in rotating speed, total current variation in a power circuit is stable, a voltage of the circuit is almost free of fluctuation, and the circuit is free of heating and burning hot phenomena; due to the adoption of frequency conversion stepless speed regulation, the spindle is stable in speed variation in rotating process, the surface of a steel ball is not affected by a non-uniform external force due to the fact that the steel ball is free of sudden jump phenomenon in machining process inside the spindle, the risk of the damage possibility that the surface of the steel ball is scratched, gnawed and burnt is greatly reduced, the machining quality of the steel ball is favorable for being improved, and the machining quality of the steel ball is guaranteed.
Description
Technical field
The utility model relates to a kind of accurate steel balls ball crusher axis system converter plant, the converter plant of specifically a kind of stepless speed regulation.
Background technology
In the existing apparatus, the original transmission system of main shaft is the 24KW three-speed motor, drives main shaft by gear and rotates.Original three-speed motor rotating speed control is carried out step speed regulation by contactor, the time relay etc., and speed is respectively 60r/min, 80r/min, 120r/min.
Because original speed governing is step speed regulation, in the rate conversion process, occur easily that the speed governing that the phenomenons such as contactor phase shortage, time relay timing be malfunctioning cause is out of control, the faults such as motor power supply phase shortage burns out, electrical network tripping operation.In the step speed regulation process, the instantaneous variation of electric current (increase) easily causes the power supply moment pressure drop of supply network, and grid supply quality is brought impact.Main shaft is in normal processes, owing to cause (technological requirement) main shaft of pressure being arranged in the rate conversion process, belonging to band pressure carries out, load characteristic is heavier, cause that the electric current in the conversion sharply increases, powerful electric current easily causes the fluctuation of electrical network, causes the circuit heating, the destruction of accelerating power source cable insulation.
Because the main control of original rate conversion process is relatively simple; to the various protections of the motor weak tendency that seems; it is higher that motor often burns out the frequency because of the factor such as stuck, the load surge of bearing, humidity, high pressure; both be unfavorable for producing continuously, stable operation; increased simultaneously maintenance cost, can not effectively reduce production costs.
Because step speed regulation, in the process of velocity variations, because the unexpected increase of speed or reduce, so that the speed of mainshaft can not get stable, the reliable variation, cause the steel ball of positive work in-process because of the variation of spindle speed, cause steel ball surface produce scratch, chew, the mass defect such as burn, the quality of product brought have a strong impact on.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of curent change is stable, speed governing changes stably axis system converter plant.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of accurate steel balls ball crusher axis system converter plant, and its innovative point is: comprise frequency converter, motor, gear and main shaft;
Wherein frequency converter links to each other with the input of motor, and the output of motor links to each other with the input of gear, and the output of gear links to each other with main shaft, and described frequency converter is the frequency converter of 30KW, and described motor is the main electricity of 24KW three speed.
The utility model has the advantage of: with the mailing of original contactor==after step speed regulation changes the frequency converter stepless time adjustment of practical 30KW into, the speed of mainshaft is steady, power circuit ancestor curent change is stable, and circuit voltage is not fluctuation almost, and circuit not have to generate heat, hot phenomenon; Because frequency converter inside is a lot of to the protected location of motor, when motor occurs that bearing is stuck, oil starvation, phase shortage, when waiting phenomenon over the ground, frequency converter can in time be diagnosed, and protection is shut down automatically, simultaneously the digital fault attribute that shows, the phenomenon that motor burns out for some reason reduces greatly, continuous, stable, the reliability service that are conducive to produce have on the one hand improved production efficiency, simultaneously, reduce the maintenance and repair cost, thereby effectively reduced production cost; Owing to adopting variable-frequency stepless speed-regulating, main shaft is in rotation process, velocity variations is steady, steel ball is in the inner process of main shaft, owing to there not being saltation electrophoresis, the surface of steel ball can not be subject to the impact of external force inequality, the destruction possible risk that the surface is scratched, chews, burns reduces greatly, help to improve the quality of steel ball processing, guaranteed the quality of steel ball processing, satisfy client's demand; After adopting frequency control, because in some specification section steel ball processing process, require low speed, low pressure, overcome original step speed regulation and had to use the sorry of middling speed or high speed, general frequency converter timing can satisfy process requirements between 30Hz-40Hz, than original mailing speed governing, saves energy 20%-40% effectively reduces the productive power cost.
Description of drawings
Fig. 1 is the speed change schematic flow sheet of converter plant of the present utility model.
The specific embodiment
By schematic diagram shown in Figure 1 as can be known, accurate steel balls ball crusher axis system converter plant of the present utility model is comprised of frequency converter 1, motor 2, gear 3 and main shaft 4.
Wherein frequency converter 1 links to each other with the input of motor 2, and the output of motor 2 links to each other with the input of gear 3, and the output of gear 3 links to each other with main shaft 4.Frequency converter 1 practicality be the frequency converter of 30KW, what motor 2 used is 24KW three fast main motors.
The operation principle of converter plant of the present utility model is: when needs are regulated the rotational frequency of ball crusher main shaft, at first by regulating frequency converter 1, changed again the rotating speed of motor 2 by the working power frequency mode that changes motor 2 by frequency converter 1, and main shaft 4 drives rotation by motor 2 by gear 3, gear 3 is constant simultaneously, then the rotating speed of motor 2 has changed, and the rotational frequency of corresponding main shaft 4 has also changed accordingly.
