Embodiment
The object of the invention is, in order to solve the assembling of existing main spindle box 4 and the deficiency in characterization processes, to realize main spindle box 4 and just can complete whole action request before loading onto lathe, and carry out main shaft speed change detection and walkaway.
As Figure 1-5, the present invention is control desk 1, hydraulic power unit 2 accesses main spindle box 4 respectively by terminal box 3; Control desk 1 is provided with control panel 5, and the control knob of control panel 5 exports each actuating of relay in test instruction control main spindle box 4 respectively by Programmable Logic Controller 6, thus tests each function of main spindle box 4.Control panel 5 is provided with load meter 7, in test process, carry out overcurrent-overvoltage detection to each circuit.
Lead-out terminal Q10 or Q7 of Programmable Logic Controller 6 is by auxiliary reclay KA1, KA2 adhesive, and the contactor KM1 of drive shaft motor 8 or KM2 adhesive, control spindle drive motor 8 rotating; The output point Q3 of Programmable Logic Controller 6 controls brake coupling 9 by relay K A6 adhesive and works; Output point Q5 or Q4 of Programmable Logic Controller 6 controls feeding clutch 10 by relay K A4, KA5 adhesive and works; Contactor KM3, KM4 that output point Q1, Q2 of Programmable Logic Controller 6 connect quick travel motor 11 control its forward and reverse rotation; The output point Q6 of Programmable Logic Controller 6 operates speed change oil cylinder 13 by relay K A3 adhesive Controlling solenoid valve group 12 and works.
Control panel 5 is provided with selector button, spindle drive motor 8 one direction pulsation rotation continuously in short speed-change process on time; When length reaches more than 3 seconds by selector button, then spindle drive motor 8 forwards are once reversed pulsation and rotate.The test duration of speed change oil cylinder 13 is 180 seconds.
Concrete test philosophy of the present invention is as follows:
Main shaft crawl and the forward and reverse rotation of continuous print: the crawl on control panel 5 or Continuous Selection knob are chosen crawl position, press lower main axis forward or reverse button, auxiliary reclay KA1 or KA2 adhesive is made by output Q10 or Q7 of Programmable Logic Controller 6, drive contactor KM1 or KM2 adhesive, at this moment spindle drive motor 8 obtains electric rotation, and release button motor stops.As by crawl or continuously knob select when continuous position, repeat above-mentioned same operation, then spindle drive motor 8 continuous rotation, now only have by lower main axis stop button, motor stops.Wherein the quick stopping of main shaft is realized by principal shaft braking clutch coupling 9.Because main spindle box 4 internal gear driving-chain is long, so the moment of inertia of main shaft is larger.Under a flowing mode, when unclamping the forward and reverse button of main shaft, the output point Q3 of Programmable Logic Controller 6 makes relay K A6 adhesive, at this moment brake coupling 9 electric, main shaft is stopped rapidly.Under continuation mode, need by after lower main axis stop button, the output point Q3 of same Programmable Logic Controller 6 makes relay K A6 adhesive, brake coupling 9 obtains electric, and main shaft stops rapidly.
Main shaft is feeding forward or backwards: first need the main shaft crawl on control panel 5 or continuous knob to be placed in continuous position, press lower main axis forward or reverse button, spindle drive motor 8 drives main shaft to start to rotate, now press forward feeding or feed reversing button, Programmable Logic Controller 6 makes relay K A4 or KA5 adhesive by output point Q5 or Q4, at this moment feeding clutch 10 obtains electric, drives main shaft to carry out axial feed motion forward or backwards.
The quick movement of main shaft axis: the quick movement of main shaft is realized by the transmission of screw mandrel and nut through reducing gear by a 3KW AC motor again.Press the forward top button on control panel 5, the output point Q2 of Programmable Logic Controller 6 makes contactor KM3 adhesive, and quick travel motor 11 rotates forward, and main shaft is interior to outer quick movement from main spindle box 4; Press reverse top button, Programmable Logic Controller 6 output point Q1 makes contactor KM4 adhesive, the reverse rotation of quick travel motor 11, and main shaft is mobile fast to main spindle box 4 li.
The shift speed change of main shaft: the change of main shaft rotational speed realizes main shaft from 3.5r/mim---700r/min totally 23 grades of rotating speeds by changing the ratio of gear coordinated between different gear in main spindle box.Press main shaft speed change button on control panel 5, Programmable Logic Controller 6 output point Q6 makes relay K A3 adhesive, speed change solenoid valve group 12 obtains electric, at this moment in main spindle box, five speed change oil cylinders 13 drive fork to change the position of power shift gear according to the oil circuit that the rotary valve under speed disk distributes, thus realize different ratio of gear, to reach the rotating speed of speed disk indication, spindle drive motor is under the control of Programmable Logic Controller 6 program simultaneously, realize pulsation to rotate, so that each shifting gear engages very well.Speed-change process T.T. controlled at 180 seconds, because this time is enough to ensure completing of all gear shifting operation.Selector button is a button dual-purpose, namely short by with long by having any different.This is programme controlled by Programmable Logic Controller 6.In short speed-change process on time, the continuous one direction pulsation of spindle drive motor rotates, and rotates the situation of a whole circle when now can observe gears meshing; When length reaches more than 3 seconds by selector button, can then spindle drive motor 8 forwards be once reversed pulsation and rotate, now can observe gear and put rapidly and determine that whether speed-change process is normal in place under the driving of fork.
The present invention allows the main spindle box 4 assembled before loading onto lathe, can to the device that action each on casing is tested on a station, can complete main shaft each shelves speed change, main shaft crawl or the forward and reverse rotation of continuous print, axis feeding, boring bar quick movement, casing clamping or loosen main shaft and casing lubrication and last main spindle box cleaning etc., and load condition when rotating to main shaft by the instrumental observation on operator's console, use as long as the main spindle box crossed by this test bed testing just directly can load onto lathe.This testing table solves main spindle box for a long time and has loaded onto the backward technique needing being dismounted for multiple times, repeatedly adjust after lathe is pinpointed the problems again, substantially increase work efficiency, reduce labour intensity, solve the contamination problem because leakage of oil during being dismounted for multiple times causes.Cleaning oil uses, so also reduce the manufacturing cost of main spindle box 4 owing to can repeat to reclaim.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that technical solution of the present invention is carried out, or directly apply to other occasion, all within protection scope of the present invention without improving.
