Carrier mechanism is made up of preceding lifting mechanism, back lifting mechanism, the unidirectional translation mechanism of reciprocal translation mechanism in upper strata and lower floor, finishes the automatic revolution and the index(ing) feed of workpiece.
The reciprocal translation mechanism in upper strata is made up of rack-and-pinion transmission pair, pawl ratchet transmission pair, chain sprocket transmission pair, upper strata truss, and gear one rack gear, ratchet one ratchet mechanism, chain sprocket transmission pair are separately fixed on the truss of upper strata.
The rack-and-pinion transmission pair is finished the to-and-fro movement of upper strata truss.
The pawl ratchet transmission pair realizes that the single direction of workpiece moves horizontally, and when the upper strata truss travelled forward under the driving of rack-and-pinion transmission pair, click did not influence motion, makes chain not transmit frock with the motion of upper strata truss; When the upper strata truss moved backward, ratchet blocked ratchet, made sprocket wheel to move, gear frame moves backward, chain is moved around sprocket wheel, and chain moves relative to gear frame again in the gear frame motion fast backward, thereby promotes the distance that frock moves a frock backward.
Horizontal door is installed in reciprocal translation mechanism front end below, upper strata.
Frock is finished by preceding lifting mechanism, back lifting mechanism respectively in the VTOL (vertical take off and landing) at two ends.
Lifting mechanism, back lifting mechanism such as Fig. 4 before preceding lifting mechanism, the back lifting mechanism, be made up of motor-step-down gear, chain sprocket transmission pair, line slideway, slide block and hanger plate etc., preceding lifting mechanism, back lifting mechanism are installed in the inboard of casing rear and front end respectively.Motor-step-down gear drives drive sprocket, drives the hanger plate that is fixed on the line slideway slide block along the line slideway vertical movement by chain, and hanger plate is hung up lifting and the decline that the frock hanger is realized frock.
Before lifting mechanism be open at vertical gate, after the reciprocal translation mechanism in upper strata gone out body of heater, frock is loaded in upper water flates pass on the actuation mechanism, at this moment, horizontal door is opened, preceding lifting mechanism moves downward below lower floor's unidirectional translation mechanism frock hanger again, be pushed and mention frock after putting in place etc. frock, finish full cycle.
Back lifting mechanism is that the frock that upper water is flated pass in the actuation mechanism is dropped on the slide rail of the unidirectional translation mechanism of lower floor, its need earlier frock from the upper strata reciprocal translation mechanism slide rail mention, after the reciprocal translation mechanism in upper strata advances to certain position, back lifting mechanism is being put forward frock and is being descended, on the slide rail of falling the unidirectional translation mechanism of lower floor, release by the unidirectional translation mechanism of lower floor again.
The unidirectional translation mechanism of lower floor adopts the chain sprocket transmission pair, promotes frock and do unidirectional moving horizontally on lower floor's guide rail.When after after lifting mechanism transmits frock, the unidirectional translation mechanism of lower floor just pushes away frock forward the distance of a frock, makes frock to be mentioned by preceding lifting mechanism.
The drive-motor of the utility model carrier mechanism adopts step-down gear and the integrated speed control by frequency variation motor special of motor.
Control device comprises as Fig. 4, light current control device and heavy-current control device shown in Figure 5.Adopt programmable logic controller as central controller, whole inputs and output signal are handled and controlled by sequence of control.
The major control original paper is inserted in the light current controlling box, the forceful electric power power element is inserted in the heavy-current control case, the device that temperature control adopts the temperature PID controller driving solid state relay that has dual PID function to carry out temperature is accurately controlled, and error is no more than 2% (± 2 ℃).Scram button and safe grating are installed to ensure safety at stevedoring face, operating mechanism adopts automated cycle control and manually control is reliable to ensure flexible operation.
The utility model working process is as follows:
As shown in Figure 1, after the startup, horizontal door and vertical gate are all closed, workpiece is at the stove internal heating, load workpiece this moment in the frock that rests on the stove gate place, press acknowledgement key after finishing, lifting mechanism is mentioned upper limit position with frock before this moment, vertical gate is opened then, the reciprocal translation mechanism in upper strata moves forward to anteposition, and preceding lifting mechanism begins to descend, and frock is placed on the reciprocal translation mechanism in upper strata stops, back lifting mechanism also begins to descend, and the frock in the reciprocal translation mechanism in the upper strata of mentioning in advance is put in the unidirectional translation mechanism of lower floor.The reciprocal translation mechanism in upper strata begins to retreat to the position, back, the effect of the pawl ratchet transmission pair by wherein, make the frock on it move to the position, back, vertical gate is closed then, horizontal door is opened, preceding lifting mechanism begins to continue to drop to the lower position, the unidirectional translation mechanism pushing mechanism of lower floor begins to push away forward frock and returns to anteposition, lifting mechanism rises before this moment, continue to rise to meta (promptly picking and placeing the door place of workpiece) after mentioning the frock in the unidirectional translation mechanism of lower floor, simultaneously the back lifting mechanism rises, and mentions frock in the reciprocal translation mechanism in upper strata to upper limit position.Horizontal door is closed then, and the frock that workpiece is housed so just is enclosed in stove internal heating for some time, just can repeat next working cycle then.
Owing to all disposed high precision line slideway director element for each moving parts, carrier mechanism operates steadily reliably, kinematic accuracy is high thereby make, and noise is little.
Because the drive-motor of carrier mechanism adopts step-down gear and the integrated speed control by frequency variation motor special of motor, so has compact construction, operate steadily speed-regulating range width, characteristics such as the fuselage thermal value is little, and is durable in use.
Owing to adopt programmable logic controller as central controller, by sequence of control whole inputs and output signal are handled and controlled, it is complete to have controlled function, and adaptive faculty is strong, revises easily characteristics easy to maintenance.
