Abstract
The invention relates to a frequency-variable speed-adjust power head, which uses the motor controlled by frequency-variable speed adjuster, uses 2-step belt transmission speed reducer to transmit different speeds to the main axle of power head; said power head has stepless speed adjustment; the low-speed section has high power output; after 2-step speed reduction, the motor still has high rotation speed, when the main axle is low speed; therefore, the low-speed section has high power output; and the belt transmission can overcome impact, vibration and large noise, to improve the stability.
Description
Affiliated technical field
The present invention relates to the machining equipment in the machine-building, especially unit head.
Background technology
At present the unit head in the machining equipment generally is that motor drives the dynamic head main spindle rotation through the gear graduation structure, and being used in the gear more, the method for gear changing changes the dynamic head main spindle rotating speed.Conversion rate is cumbersome, particularly when unit head is worked, and can not speed change.In the recent period, the technology of carrying out speed governing with the motor of Frequency Converter Control is widely used, and not dull speed is very convenient, and can realize stepless speed regulation.But, the little defective of motor power output when having the slow-speed of revolution.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of variable-frequency control dynamic head is provided, can pass to the multiple rotating speed of dynamic head main spindle, have the stepless speed regulation performance, and low speed segment has bigger power output.
The objective of the invention is to realize as follows: variable-frequency control dynamic head is made up of motor, belt reducing gear and the dynamic head main spindle case of variable-frequency governor control, and the support that bottom face profile is consistent with the dynamic head main spindle box back is fixed on the rear end of main shaft casing with bolt, packing ring.The small pulley of power transmission shaft one end is connected with the main shaft belt with the main shaft belt wheel of unit head rear end, and the electrical machine belt pulley on the vertical machine of the big belt wheel of the power transmission shaft other end and variable-frequency governor control is connected with motor belt.Power transmission shaft is contained in the bearing block by bearing.Bearing block is contained in above the median septum by 4 corresponding grooves on 4 groups of bolts, packing ring, nut and the support median septum, and the position of 4 grooves and length should be able to be passed through the moving shaft holder position on the median septum, satisfies the needs of tensioning main shaft belt.The vertical machine of variable-frequency governor control by contour pad with 4 groups of bolts, packing ring, nuts be fixed on the support upper plate above, the position of the groove that bolt passes on the support upper plate and length should be able to be passed through the mobile motor position, satisfy the needs of tensioning motor belt.Motor shaft, power transmission shaft and dynamic head main spindle axial line are in a plane and be parallel to each other.
The advantage that this variable-frequency control dynamic head has is: owing to adopt frequency control, can set the multiple rotating speed that dynamic head main spindle needs very easily, can also realize stepless speed regulation.After 2 grades of decelerations, motor still has high rotational speed during the main shaft low-speed running, so low speed segment has the output of bigger power, to satisfy the machining needs.Variable-frequency control dynamic head is adapted to have the plant equipment of digital control system especially.Because reducing gear adopts belt transmission, the big defective of impact, vibrations and noise that habitual gear drive produces before having overcome makes spindle operation steady, has improved the level of whole plant equipment.
