Also face rotor feeding system 200 is transferred come the rotor for holding of hovering directly over it, is press-fitted the built in pressure sensor of seat 4044, can
The situation of change of press-fitting force during monitoring press-fitting.
Because servo electric cylinders 4041 are contributed very greatly, the present invention is using the first 4042 connection servo electric cylinders 4041 of floating connection with sliding
Block 4043, it can be used for absorbing cross force (sliding block 4043 and line slideway 4045 by the flexible connection of floating connection first 4042
It is slidably connected using dovetail groove, but still small transverse shifting can occur for inevitable sliding block 4043), prevent servo electric cylinders 4041
The direction of power and stress point be not on one wire when stretching out for output end so that its external part deforms or fracture, extends servo
The service life of electric cylinders 4041.
Shown accurate measurement mechanism 405, it may include the displacement for being installed on the top plate 4012 of workpiece positioning compression mechanism 401 passes
Sensor, the measuring staff 4051 of amount of movement (also measurable gap) as measured above are extended downwardly from setting by top 4012, in addition to dress
Assigned in compositions such as the above-mentioned pressure sensor in press-fitting seat 4044, the elastic mechanisms of application pretightning force for measuring pressure.
By upper, by high accuracy press-fitting and clearance control, self-centering structure such as is used, high-precision servo press is pressed
Match somebody with somebody, and after press-fitting terminates, gap can be rechecked immediately, in press-fitting and position fixing process, compressor box is solely subjected to measuring force and (is less than
15N)。
The operation principle of press mounting system 400 is as follows：
Compressor is sent to assembly station with the working plate on branch transmission line 1021, and block piece stops working plate, working plate
Jacked by the working plate lifting body 402 below the position and depart from branch transmission line 1021, rise to position to be assembled；
Workpiece is felt relieved and bent axle axial positioning mechanism 403 carries out workpiece centering compressor inside crankshaft circumference simultaneously to compressor
Positioning, automatic measurement simultaneously carry out rotor press-mounting preparation by gap width at rotor after the rotor press-mounting of setting and crankcase；
Rotor is transported to assembly station, positioned at rotor pressure by transport mechanism 404 before and after rotor in rotor feeding system 200
With the surface of seat 4044 and holding of hovering；
Accurate press-fitting mechanism 404 rapid operation of servo-electric, driving rotor press-fitting seat 4044 are moved up, and carrying is described to be turned
After son, transport mechanism 404 discharges rotor and reset of retracting before and after the rotor in rotor feeding system 200；Carry the rotor
Rotor press-fitting seat 4044 continued to move up by driving, through working plate on corresponding hole, prop up top workpiece positioning compression
The pressure heads mechanism 4011 of mechanism 401, to be pressed rotor；
During rotor is pressed, pressure assembling force, press fitting direction (i.e. vertical direction) are measured by above-mentioned accurate measurement mechanism 405
Displacement, the upward gap of rotor in press fitting.Specifically, when workpiece touches the measuring staff 4051 of accurate measurement mechanism 405,
Displacement and gap are determined in the change of sensor moment monitoring measuring staff 4051, are coordinated the pressure of pressure sensor to implement control and are surveyed
Amount, carries out accurate press-fitting.
Stop press fitting, measurement gap, rotor press-fitting seat when being pressed into the gap width or displacement that rotor reaches set
4044 are lowered back to by driving, and (reset includes each system reset：Working plate lifting body 402 is descending, the compressor assembled
Come back on branch transmission line 1021), block piece clearance working plate.
In rotor process of press in, if pressure assembling force does not meet the relation of the stroke versus force curve of setting, rotor press-fitting seat 4044
Process of press in can be stopped by driving auto-returned, terminate to be pressed and alarm on screen.
Therefore the equipment can automatically control the press-in size during rotor cold pressing dress, difference is pressed in process of press in
Enter corresponding pressing-in force of size etc. (displacement-force curve can be shown), in addition, can also be according to technological requirement arbitrarily setting press fitting in advance
Crankshaft axial gap value afterwards, according to the different press-fitting strategy of different cultivars workpiece setting, according to different compression distances and pressure
With power, the equipment can complete the overall process of press fitting according to setting value automatically, it is ensured that the parameters requirement of rotor press-mounting, be discontented with
Foot or (such as pressing-in force is too small or excessive) beyond parameter area, equipment meeting automatic alarm prompting, really reliably ensure that
Quality during rotor press-mounting.
Control system, including industrial computer and embedded industrial control system.It is combined by industrial computer and embedded industrial control system,
Good man-machine interface, abundant data processing and reliable control are realized, for above-mentioned overall transfer, assembling process
In co-ordination between above-mentioned each system, mechanism control.
The operation principle of compressor drum cold pressing system of the present invention is further illustrated below, under control of the control system,
Present system works as follows：
First, in working plate Transmission system 100, compressor to be assembled transmits through working plate in main transmission line 1011,
And reach and be blocked after ad-hoc location, jack, push to branch transmission line 1021；
Then, compressor to be assembled transmits through working plate in branch transmission line 1021, and reach and be blocked after ad-hoc location,
Jack to press-fitting station to be assembled；
On the other hand, for rotor feeding system 200, it is by six axis robot charging equipment 200 from its truck 201
Crawl rotor to be assembled in magazine 202, and it is transferred to rotor conveying equipment 300；
For rotor conveying equipment 300, rotor is adjusted to predetermined angle by the detection of its rotor angle and adjustment mechanism 302
Degree, and will by transport mechanism 304 before and after transport mechanism 301, rotor before and after its rotor auxiliary or so transport mechanism 303, rotor
Rotor, which continues to send, is handed to press-fitting station to be assembled, and it is located at the lower section of working plate to be assembled；
Then, for press mounting system 400, felt relieved by its workpiece and bent axle axial positioning mechanism 403 carries out work to compressor
Part is felt relieved and compressor inside crankshaft is circumferentially positioned, and drives its rotor to be press-fitted seat 4044 by the accurate press-fitting mechanism 404 of servo-electric
Move up, contact, carry to continue to move up after rotor to be assembled directly over it and be press-fitted into compressor, its assembling process and by essence
Close measuring mechanism 405 is monitored and controlled in real time.
Afterwards, after having assembled, press mounting system 400 resets, and the compressor assembled declines multiple in working plate lifting body 402
Position, after touching branch transmission line 1021 again, it is cleared, and up to being blocked after ad-hoc location, jack, push to main transmission line
1011。
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
