Description
Technical field
The present invention is used for mechanical assembly frock field, particularly relates to a kind of valve nozzle and positions auxiliary positive press-fitting tool and the method applying this frock to press-fit valve nozzle.
Background technology
The annual production of China's automobile in recent years hits new peak continuously, and the safety and stability of automobile is the most increasingly paid close attention to by people.Anti-lock braking system ABS is increasingly becoming the standard configuration of automobile, regulation according to country's relevant laws and regulations, Some vehicles needs solar obligation ABS system, the most not issue licence plate, this makes China have and the chance of external intratype competition in this field, and is successively applied in terms of passenger vehicle, truck, lorry, trailer, car.
But apply the time short at home due to ABS system, the packaging technology of each assembly and assembly tool imperfection.Gas brake-pressure controller is as the main executor in ABS, and pressure regulator valve nozzle is assembly important in actuator, and its depth dimensions precision assembled and air-tightness can directly influence the combination property of product.Because the overall dimensions of casting workpiece exists error, thus cause processing dimension, the center etc. of relevant pilot hole to there is also certain error, and old valve nozzle crimping pressure head is directly with vapour hydraulic booster press ram links together, valve nozzle is placed directly in above valve nozzle mating holes and does not has positioning sleeve auxiliary fixed vertical, when valve nozzle crimping pressure head center and following center, valve nozzle press-fit hole be not at a vertical line, valve nozzle press-fits and is easy for pressing askew, and pressure is partially and valve nozzle depth dimensions is unstable, change is big.Exactly because valve nozzle press-fited in kind, easily pressure was askew, pressure is inclined, poor sealing, and qualification rate is low, so just needing plus being coated with this operation of fixing seal glue.And being coated with this operation of fixing seal glue is a loaded down with trivial details operation, will valve nozzle uniform external diameter coat a circle fixing seal glue, press-fited after want to wipe clean extrude unnecessary fixing seal glue during press-fiting at once, such packaging technology efficiency is low, complex operation, Staff activity is the highest.
Summary of the invention
For solving the problems referred to above, the present invention provides a kind of assembly operation simple, and production efficiency is high, sealing and depth dimensions are stable, global design is safe and reliable, frock low cost, and the follow-up valve nozzle that can realize automatic production line assembling positions auxiliary positive press-fitting tool and the method applying this frock to press-fit valve nozzle.
The technical solution adopted for the present invention to solve the technical problems is: a kind of valve nozzle positions auxiliary positive press-fitting tool, including workpiece positioning seat, location guide pin bushing and pressure head, described location guide pin bushing includes embedding connecting location division and being positioned at outside described connection location division to guide the guide part of pressure head in workpiece, it is provided with shoulder hole inside the guide pin bushing of described location, described shoulder hole includes being positioned at the valve nozzle opening section connecting location division and the pressure head hole section being positioned at guide part, the top sidewall of described pressure head hole section is provided with locating surface, described locating surface is parallel with the bottom end face of location guide pin bushing, described pressure head includes the press-fit portion that can penetrate described valve nozzle opening section and the guide portion that can coordinate with described pressure head hole section, the top sidewall of described guide portion is provided with the confined planes can fitted with described locating surface, described confined planes is parallel with the bottom end face of described pressure head.
It is further used as the improvement of technical solution of the present invention, in the middle part of the bottom end face of described pressure head, is provided with escape groove.
Being further used as the improvement of technical solution of the present invention, the valve nozzle opening section of periphery and shoulder hole that described location guide pin bushing connects location division is coaxially disposed.
The present invention also provides for a kind of method applying the auxiliary positive press-fitting tool in above-mentioned valve nozzle location to press-fit valve nozzle, comprises the following steps: workpiece is put into workpiece positioning seat and clamps；Again the connection location division of location guide pin bushing is embedded in workpiece, make valve nozzle opening section dock completely with the valve nozzle press-fit hole on workpiece；Valve nozzle is put into location guide pin bushing, then pressure head is put in the guide pin bushing of location, and make the lower surface of pressure head prop up the end face of valve nozzle；Finally the top of pressure head apply external force with valve nozzle press-fit hole that valve nozzle is completely forced on workpiece in.
Beneficial effects of the present invention: compared with prior art, the present invention has the effect that
1. production efficiency improves, and originally press-fiting a valve nozzle needs about 24 seconds, and press-fiting now a valve nozzle only needs i.e. can complete for 12 seconds；
2. will not press partially, press askew valve nozzle, also will not damage workpiece by pressure, the valve nozzle depth dimensions after press-fiting is stable；
3. decreasing painting, the cumbersome process of wiping fixing seal glue, qualification rate and production efficiency improve, and the enthusiasm of employee also improves, and operation mood is the most joyful；
4. valve nozzle press-fits depth dimensions tolerance and is become ± 0.05mm from ± 0.1mm, performance more stability.
It is simple that this valve nozzle positions auxiliary positive press-fitting tool assembly operation, and production efficiency is high, and sealing and depth dimensions are stable.Global design is safe and reliable, frock low cost, and the follow-up automatic production line that can realize assembles；Positioning, with valve nozzle, the gas brake-pressure controller of valve nozzle that auxiliary positive press-fitting tool press-fits and be applied to the constant product quality of passenger vehicle, truck, lorry, trailer, reliability is high, has sold Ge great automobile main frame maker, and market reaction is good.
