Description
Technical field
The utility model is related to a kind of pin toolings, especially turbocharging shell pin press-in device.
Background technology
Turbocharger is actually a kind of air compressor, increases air inflow by compressed air.It is to utilize hair
The exhaust gas inertia impulsive force of motivation discharge pushes the indoor turbine of turbine, turbine to drive coaxial impeller again, and impeller force feed is by sky
The air that air cleaner pipeline is sent is allowed to supercharging and enters cylinder.When engine speed is speeded, the exhaust gas velocity of discharge turns with turbine
Speed, which also synchronizes, to be speeded, and impeller just compresses more air and enters cylinder, and pressure and the density increase of air can burn more
Fuel, the corresponding rotating speed for increasing fuel quantity and adjusting engine, so that it may to increase the output power of engine.It enters the lists
Sport car is generally equipped with turbocharger on the engine, so that automobile bursts out the power of bigger.Engine is by fuel in gas
In-cylinder combustion generates power, and the fuel quantity of input is limited by sucking cylinder air amount, generated power also can
It is restricted, if the runnability of engine has been in optimum state, being further added by output power can only be more by compressing
Air enters cylinder to increase fuel quantity, improves work by combustion ability.Turbocharger is that engine can uniquely imitated in work
Increase the mechanical device of output power in the case that rate is constant.
Installation pin is needed to be positioned on turbocharging shell, the pin hole of pin and turbocharging shell is interference fit,
Therefore frock clamp is needed to be pressed into pin in the pin hole of turbocharging shell.And existing fixture is inconvenient to use,
Or the pin installation of not applicable turbocharging shell, such as the pin press-in device that Chinese patent CN106736421A is announced, the pin
Follow closely press-in device, can not only fast and easy be pressed into pin, and rejection rate is low, and process velocity is fast, and production efficiency is high；It includes hanging
The end face of the pedestal set, the pedestal is equipped with sliding rail, and bottom plate is slidably connected on the sliding rail, and the bottom plate passes through fixation
In being fixed by the bracket decompressor on the driving cylinder slide on the pedestal, the bottom plate, the decompressor and punching
Air cylinder connects, and the decompressor connects vibrating disk by delivery pipe.But the equipment is not suitable for the pin of turbocharging shell
Installation.

Portion.
By using above-mentioned technical proposal, since lifting slider size is smaller, if directly connect with elevating lever, can cause
The diameter of elevating lever is smaller, and intensity is deteriorated, and the connection of lifting slider and elevating lever is realized by sliding block connecting seat.
Preferably, the bottom of the lifting groove is equipped with lift span, and lift span is communicated with the spring eye of lifting seat bottom；It is described
Elevating lever includes the upper elevating lever that diameter is sequentially increased and lower elevating lever, and the end of upper elevating lever is connect with sliding block connecting seat, and
Activity is inserted in lift span, and lower elevating lever activity is inserted in spring eye；One end of the spring is pressed in spring eye, another side pressure
On lower elevating lever, and spring pocket is on upper elevating lever.
By using above-mentioned technical proposal, keep the connection of elevating lever and lifting seat simple.
Preferably, the lifting seat is equipped with location hole, and location hole is vertical with spring eye, and passes through spring eye, location hole
Upper that gag lever post is housed, the gag lever post activity is inserted in the limit hole of lower elevating lever, and limit hole is waist through hole.
By using above-mentioned technical proposal, the shift position of elevating lever is limited, prevents movement is excessive from causing turbocharging shell
Damage.
The utility model has the advantages that compared with prior art：
Turbocharging shell pin press-in device provided by the utility model is simple in structure, accurate positioning, shop bolt indentation
Quickly.
