Abstract
The invention discloses a remanufacturing repairing technology for an automobile steering pump core. The automobile steering pump core is composed of stators, rotors and blades. The repairing process of the stators mainly includes the steps that in an environment at 35 DEG C-45 DEG C, cleaning and deoiling are performed on the stators of a steering pump through deoiling agents, and then air drying is performed; the stators, which can be repaired, of the steering pump are selected through visual inspection; through measuring, the stators, of which the abrasion degree is within 0.2 mm, of the steering pump are selected; through a high-precision numerical control paralleled surface grinding machine, the two end faces of each stator of the steering pump are ground to be flat; through a high-precision numerical control inner hole curve grinding machine, enlarging repairing is performed on the stators of the steering pump; whether the repaired stators of the steering pump meet requirements or not is measured and detected. According to the technology, the repairing rate of the old steering pump core can be increased substantially, and the quality of remanufactured products is further improved.

Manufacturing is an emerging industry again, then manufactures a product and have the capability and performance that is not less than new product, the same quality guarantee period, but its selling price only has the 40-60% of new product price.Compared with new product, then manufacture a product and can save energy 60%, material-saving 70%, Air Pollutants Emissions reduces more than 80%, is of great immediate significance to realizing energy-saving and emission-reduction.
The present invention just relates to manufacturing again of boosting pump for car steering pump core.Manufacturing again of boosting pump for car steering pump core is the core that power assistance pump for steering is manufactured again, the compositions such as the main stator of pump core, rotor and the blade of boosting pump for car steering.Stator negative camber is to contact with blade, can produce certain wearing and tearing after of long duration, the notch of rotor be also can and stator produce certain wearing and tearing, and the end face of stator and rotor also can produce wearing and tearing.The end face reparation of our domestic stator, rotor and stator to this boost pump and rotor is at present manufactured and also be there is no good method, once there is the common reparation of wearing and tearing and can not meet quality requirement, quality is had to certain influence in the pump core of boosting pump for car steering.Can only be to change, or exactly the pump core entirety of this boosting pump for car steering be scrapped to processing, change with new product, so greatly waste resource.
Summary of the invention:
The object of the invention is to overcome the deficiency of prior art, what a kind of boosting pump for car steering pump core that can repair the end face of stator, rotor and stator and rotor was provided manufactures renovation technique again, to improve product quality, improves resource utilization.
Object of the present invention is achieved through the following technical solutions:
Boosting pump for car steering pump core manufacture again a renovation technique, boosting pump for car steering pump core is made up of stator, rotor and blade, the reparation of described stator comprises the steps:
(a) under the environment of 35-45 DEG C by degreaser by power steering pump stator clean deoil, air-dry;
(b) the power steering pump stator that can repair is picked out in range estimation;
(c) pick out the power steering pump stator of the degree of wear in 0.2 millimeter by measurement;
(d) pass through high precision numerical control double-ended grinding machine by the grinding two end surfaces of power steering pump stator;
(e) by high precision numerical control inner hole curve grinding machine, power steering pump stator is expanded to reparation;
(f) whether the power steering pump stator of measuring after inspection is repaired meets the requirements.
The reparation of described rotor comprises the steps:
(a) under the environment of 35-45 DEG C by degreaser by power steering pump rotor clean deoil, air-dry;
(b) the power steering pump rotor that can repair is picked out in range estimation;
(c) adopt repairing sizes method to repair power steering pump rotor, specifically by high precision numerical control rotor notch grinding machine, the notch of power steering pump rotor is expanded to reparation;
(d) whether the power steering pump rotor of measuring after inspection is repaired meets the requirements;
(e) blade of new correspondingly-sized is coordinated with the notch of power steering pump rotor.
The reparation of the end face of described stator and rotor comprises the steps:
(a) under the environment of 35-45 DEG C, by degreaser, the end face of power steering pump stator and rotor is cleaned deoil, air-dry;
(b) power steering pump stator and the rotor that can repair are picked out in range estimation;
(c) by high precision numerical control double-ended grinding machine, stator is ground together with rotor height simultaneously to low 0.005mm;
(d) whether the power steering pump stator after measurement inspection reparation and the engagement height of rotor meet the requirements.
Beneficial effect of the present invention is:
The present invention manufactures by the reparation of the end face to stator, rotor and stator and rotor respectively again, can produce the pump core the same with new product, realization is turned waste into wealth, energy-saving and emission-reduction, the utilization rate of manufacturing again of pump core is brought up to more than 90% from 20%, increase substantially the repair rate of old boost pump pump core, and further promoted the quality manufacturing a product again.The manufacturing again of boosting pump for car steering pump core has been played to very crucial impetus.
