Description
Technical field
What the present invention relates to is the machining crankshafts lathe, and what be specifically related to is a kind of mechanism that adjusts the front and back spindle synchronous rotation of Crankshaft Machining lathe.
Combination by structural members such as worm and gears realizes the synchronous adjustment of rotating of headstock spindle before and after the Crankshaft Machining lathe, thereby before and after making the Crankshaft Machining lathe, headstock spindle obtains higher synchronous rotation precision, satisfies the requirement of Crankshaft Machining precision.
Background technology
Before and after the processing of small crank is adopted usually, the installation way of main spindle box and fixture is processed bent axle; The synchronous rotation of headstock spindle before and after driving simultaneously with an alternating current generator adopts the splined shaft transmission to rotate between the output shaft of forward spindle case and the power shaft of rear main spindle box; Due to the existence in the gap between the driving members such as travelling gear and splined shaft, before and after can making, the output of headstock spindle is rotated and is produced the asynchronous of trace, thereby has influence on the Crankshaft Machining precision, can make the crankshaft distortion distortion when serious.With being connected between forward spindle case and splined shaft of the structural members such as worm and gear, the drive gap of main spindle box before and after being used for adjusting and eliminating, thereby before and after making the Crankshaft Machining lathe, headstock spindle obtains higher synchronous rotation precision, satisfies the requirement of Crankshaft Machining precision.
Summary of the invention
The objective of the invention is the defective that exists for overcoming above-mentioned prior art, and a kind of mechanism that spindle synchronous rotates before and after the Crankshaft Machining lathe that adjusts is provided.This mechanism realizes the synchronous adjustment of rotating of headstock spindle before and after the Crankshaft Machining lathe by the combination of the structural members such as worm and gear, thereby before and after making the Crankshaft Machining lathe, headstock spindle obtains higher synchronous rotation precision, satisfies the requirement of Crankshaft Machining precision.
The technical scheme that adopts is:
A kind of mechanism that adjusts the front and back spindle synchronous rotation of Crankshaft Machining lathe comprises forward and backward main spindle box body, forward and backward main shaft, forward and backward mainshaft gear, forward and backward power transmission shaft, forward and backward shaft gear, front output shaft, front output shaft gear, rear power shaft, rear input shaft gear, reaches the spindle synchronous rotating mechanism.before, rear main shaft, before, inter-axle shaft, front output shaft is before correspondence is assemblied in respectively, on rear main spindle box body, front output shaft, rear power shaft is before correspondence is assemblied in respectively, on rear main spindle box body, before, rear mainshaft gear is before correspondence is assemblied in respectively, on rear main shaft, before, the inter-axle shaft gear is before correspondence is assemblied in respectively, on inter-axle shaft, front output shaft gear is assemblied on front output shaft, rear input shaft gear is assemblied on rear power shaft, it is characterized in that described spindle synchronous rotating mechanism, comprise worm gear case,-worm gear, worm screw, end cap, lock-screw, locking nut, worm gear case is assemblied on front output shaft, assembling the first flat key between front output shaft and worm gear case, screw is adjusted in assembling first on worm gear case, first adjusts screw withstands on described the first flat key.Worm gear is assemblied between worm gear case and splined shaft, worm screw is assemblied between worm gear case and worm gear, lock-screw and locking nut are assemblied between worm gear case and worm gear, assembling the second flat key between worm gear and splined shaft, screw is adjusted in assembling second on worm gear, second adjusts screw withstands on the second flat key, assembling one splined shaft on worm gear and rear power shaft, and end cap is assemblied on worm gear case.
The present invention has simple in structure, the machining accuracy advantages of higher
Operation principle:
The front and back spindle box part of Crankshaft Machining lathe is assemblied on lathe bed and confirms that front and back main shaft axiality meets the requirements, before and after worm and gear being adjusted the Crankshaft Machining lathe, the main spindle box synchronous drive mechanism is assemblied between forward spindle case output shaft and rear main spindle box power shaft again, with lock-screw and locking nut, worm gear is fastened on worm gear case, synchronous rotation detecting device is installed on the main shaft of front and back main spindle box, rotate forward spindle case output shaft with hand, the synchronous rotation situation of headstock spindle before and after being detected by synchronous rotation detecting device; When headstock spindle rotation in front and back is asynchronous, unclamp the locking nut on worm gear, drive the worm gear rotation with the allen wrench rotary worm, then with the locking of the locking nut on worm gear, the more synchronous rotation situation of headstock spindle before and after being detected by synchronous rotation detecting device; Said process so repeatedly, until the front and back headstock spindle reaches precise synchronization rotate till.
