Description

Inlet manifold subpackage frock

Technical field

The utility model relates to automobile assembling technical fields, and in particular to a kind of inlet manifold subpackage frock.

Background technique

Inlet manifold is between air throttle and engine air admittance door, and why referred to as manifold, is because air enters solar term Behind the door, after manifold buffering system, just in this disagreement, the quantity of corresponding engine cylinder has air flow channel if four cylinder engines Air is directed respectively into each cylinder by four, five cylinder engine Ze You five.For NA Naturally Aspirated Engine, due to inlet manifold After air throttle, so can not be drawn onto enough air when engine throttle aperture is small in cylinder, it is true to will result in manifold Reciprocal of duty cycle is high；And when engine throttle aperture is big, the vacuum degree in inlet manifold will become smaller.Therefore, injection fuel feeding engine all can A pressure gauge is installed in inlet manifold, supply ECU determines engine load, and gives suitable oil spout.

The design of inlet manifold is also to take a lot of learning, in order to which the combustion position of each cylinder of engine is identical, each cylinder Manifold length and curvature will be identical as far as possible.Since engine is to complete running program by four strokes, so engine Each cylinder can air inlet in a pulsed fashion, empirically, longer manifold be suitble to the slow-speed of revolution operating, and shorter manifold then be suitble to height Rotation speed operation.So some vehicles can use variable-length intake manifold or continuous variable-length inlet manifold, make engine each Revolving speed domain can play preferable performance.

In automobile assembling, the components of the air throttle and some small volumes in inlet manifold can be assembled in advance, Formation packing assembly, which is re-fed on engine general assembly line, completes overall assembling, is by the way of during existing packing It is artificial using clamp be voluntarily fixed inlet manifold and carry out the screw-driving of air throttle again fix, do not have during the packing The positioning of packing components is fixed, be easy to cause packing relative position not in place simultaneously as needing artificially to be fixed very It is time-consuming and laborious, operating procedure and time are increased, assembly beat is reduced, production efficiency is low.

Therefore, in order to solve the above problem, a kind of inlet manifold subpackage frock is needed, air inlet discrimination voluntarily can be positioned and fix Pipe, it is only necessary to which the connection bolt between air throttle and inlet manifold is tightened by pneumatic impact spanner and be can be completed by air throttle in placement The assembly for dispensing assembly takes out packing assembly along Z-direction, greatly improves assembling quality and saved installation step And the time, improve productive temp.

Utility model content

In view of this, inlet manifold subpackage frock is provided the purpose of the utility model is to overcome defect in the prior art, Voluntarily can position and fix inlet manifold, it is only necessary in placement air throttle by pneumatic impact spanner by air throttle and inlet manifold it Between connection bolt tighten can be completed packing assembly assembly, along Z-direction take out packing assembly, greatly improve It assembling quality and has saved installation step and time, has improved productive temp.

The inlet manifold subpackage frock of the utility model, including bottom plate are detachably provided with cushion block and one on the bottom plate To scotch, when positioning inlet manifold, two pieces of scotch are inserted into the gap between the different adjacent manifolds of inlet manifold respectively In, plant fixation is carried out to four Dao Huo, five inlet manifold, without stepping up, when assembling air throttle, prevents inlet manifold about the z axis Rotation, facilitates air throttle to assemble；The cushion block passes through positioning pin and is connected to the bottom plate, which can be with the peace of spacer pad Holding position assembles needs to adapt to the inlet manifold of different model, and the relative position of the cushion block and scotch is adjustable, raising The versatility of inlet manifold subpackage frock is adapted to the packing of different automobile types inlet manifold, saves frock cost, improves production effect Rate；

The cushion block and scotch carry out positioning and fixing to inlet manifold, instead of manually operation is gripped, save Operating procedure and time improve working efficiency and quality.

Further, the scotch is L shape vulcanie block, is connected to the bottom plate, L-type vulcanie block by bolt It can guarantee inlet manifold surface of not damaging when assembling inlet manifold, while be supplied to the enough Z-directions of inlet manifold Fastening force prevents inlet manifold from turning about the Z axis, and the scotch of L-type ensure that the installation contact area bigger with the bottom plate, Guarantee the mounting stability of scotch.

Further, the bolt includes the high-low side that cremorne bolt and short latch correspond to the scotch, single bolt pair The fastening force of scotch is effective, may cause inlet manifold subpackage frock and generates scotch generation spinning feelings in use Condition is fixed scotch so adding more bolts, and the length of bolt is also the shape with scotch and is arranged, L The scotch of type both can satisfy positioning intensity requirement or more save rubber material, and more convenient for the assembly of inlet manifold.

Further, the cushion block is removably connected to the bottom plate by bolt, and intensity is high, easy to connect and reliability Height is used widely in mechanical frock, can be replaced two with the model of inlet manifold to be assembled and be adjusted installation site, meet The assembly demand of more products, reduces production cost.

Further, evacuation through-hole is offered on the installation vacancy of the bottom plate, saves tooling material, it is light to meet integrated tooling Quantization requires, while saving material, reduces cost.

Further, it is provided with installation screw and handle on the bottom plate, which is set to the apex angle of the bottom plate Place, convenient for the installation of inlet manifold subpackage frock, the setting of handle can be convenient guiding and supporting and moving for inlet manifold subpackage frock.

The beneficial effects of the utility model are: a kind of inlet manifold subpackage frock disclosed by the utility model, passes through stop Block and cushion block voluntarily position and fixed inlet manifold, it is only necessary to which air throttle passes through pneumatic impact spanner for air throttle and air inlet discrimination in placement Connection bolt between pipe tightens the assembly that packing assembly can be completed, and takes out packing assembly along Z-direction, greatly mentions High assembling quality and installation step and time to be saved, has improved productive temp, inlet manifold subpackage frock overall structure is simple, The fixed operation to inlet manifold is omitted, improves assembly rhythm, improves work efficiency.
