Summary of the invention
Deficiency to the prior art existence; The present invention aims to provide stroke, power value control method and the equipment in a kind of automobile engine liquid pump assembly assembling process; Guarantee that defective workpiece is in time found in press-fiting process, guarantee the high accuracy of assembling, avoid workpiece to receive excessive forces and be damaged.
The technical scheme that the present invention adopts is:
A kind of automobile engine liquid pump assembly press-mounting stroke, power value control method; This method is provided with pressure sensor on forcing press; And on the press-loading head of forcing press, be provided with relative position adjustable and with the sender shell fragment of press-loading head insulation; The main pressure valve of forcing press is parallel with the dwell pressure valve, is provided with magnetic valve before the dwell pressure valve, and the pressure that the pressure ratio main pressure valve that the dwell pressure valve is set up is set up is low; Forcing press, pressure sensor, sender shell fragment and magnetic valve all are connected to the PLC controller, and it is following that it press-fits process:
1) maximum, minimum force are imported the PLC controller through man-machine interface before press-fiting; In press-fiting process, detect real-time force and send the PLC controller through pressure sensor; When two assembly parts pressure assembling forces surpassed maximum set value, the PLC controller provides the tension alarm and the controlled pressure machine stops to press-fit; When two assembly parts pressure assembling forces during less than minimum setting value, PLC controls to appearing loose alarm and the controlled pressure machine stops to press-fit;
2) when press-fiting when reaching design height, the sender shell fragment contacts with workpiece end face, and the sender shell fragment sends workpiece and is press-fit into place signal to the PLC controller, gets into the less packing stage of pressure by PLC controller controlled pressure machine;
3) at packing stage, system pressure switches to the pressure that the dwell pressure valve is set up, thereby avoids bearing excessive pressure at the packing stage workpiece under the effect of magnetic valve, and the pressure handoff procedure is realized by the PLC controller automatically.
Said sender shell fragment and press-loading head end face are at grade.
A kind of automobile engine liquid pump assembly press-mounting stroke, power value control appliance; The main body of this equipment is a forcing press; Which is provided with pressure sensor, and on the press-loading head of forcing press, be provided with relative position adjustable and with the sender shell fragment of press-loading head insulation, the main pressure valve of forcing press is parallel with the dwell pressure valve that set pressure is lower than main pressure valve; Be provided with magnetic valve before the dwell pressure valve, forcing press, pressure sensor, sender shell fragment and magnetic valve all are connected to the PLC controller.
Said sender shell fragment and press-loading head end face are at grade.
The present invention can control the assembly parts positional precision; Do not receive the influence of the precision of workpiece own, the pressure assembling force that press-fits process is shown and monitors, pressure assembling force is excessive or too smallly all can judge; At packing stage; The power that control is pressed on the workpiece can be not excessive, can improve through above-mentioned control to press-fit precision and yield rate, the variety of issue of avoiding existing pressing method and equipment to exist.
