Vehicle evaporator core and ear shape plate press fit device

Technical field

The utility model relates to a kind of equipment that press-fits assembling during to unit construction, relates in particular to a kind of vehicle evaporator core and ear shape plate press fit device.

Background technology

The vehicle evaporator core is as air conditioning for automobiles and core component; Its inner stream has and extraneous working media that carries out heat exchange, and existing vehicle evaporator core is many to be made up of the one group of D shape pipe that laterally arranges, fin and the flat tube etc. that are connected between the D shape pipe, for realizing that the liquid in-out pipe is communicated with the vehicle evaporator core; And take up space in order to save the liquid in-out pipe; Be convenient to the layout of pipeline, usually the liquid in-out pipe be designed to have the ear shape structure of inlet opening and fluid hole, for ease of described; Usually the liquid in-out pipe with this structure is called ear shape plate; Inlet opening and fluid hole periphery in ear shape plate bottom are provided with the boss that is used to assemble, and when assembling, only need the D shape pipe that is fitted in the vehicle evaporator core that boss is corresponding to go up and get final product.

Existing assembling mode needs earlier boss to be inserted D shape pipe, accomplishes both preparatory assemblings; Adopt the mode of artificial hammering then; Boss is inserted in the D shape pipe fully, weld through the NB stove at last, the inwall that the boss that makes ear shape plate and D shape are managed is to the state that is tightly connected.Because between the boss of ear shape plate and the D shape pipe is interference fit; The shape of ear shape plate is more complicated again, and the fit of ear shape plate is knocked in manual work, might damage the faying face between boss and the D shape pipe; Influence follow-up welding quality, also can expend the long operating time simultaneously; And percussion power is excessive, will cause the distortion of ear shape plate, influences flowing of fluid, has reduced the performance of evaporimeter.

The utility model content

For solving the deficiency that exists in the prior art; The utility model provides a kind of vehicle evaporator core and ear shape plate press fit device; It has effectively improved the assembling effect of ear shape plate and vehicle evaporator core, and the generation of having avoided ear shape plate to knock metaboly has improved packaging efficiency.

For realizing above-mentioned purpose; Vehicle evaporator core of the utility model and ear shape plate press fit device; Pre-assembled vehicle evaporator core and ear shape plate are carried out pressing; Comprise substrate, be fixed on support on the substrate, be fixed on a top of the trellis gripper shoe, be fixed on the cylinder that vertical power is provided on the gripper shoe, the clutch end of said cylinder is fixed with the briquetting that is positioned at the gripper shoe below; On substrate, be fixed with positioner, described positioner positions pre-assembled vehicle evaporator core and ear shape plate, and makes ear shape plate be positioned at the vertical below of briquetting.

As the improvement to the utility model, the bottom surface of said briquetting has the shape that matches with ear shape plate upper surface.

As improvement, below gripper shoe, be fixed with the guide post that is slidingly matched with briquetting, vertically be provided with to the qualification of the utility model.

As the qualification to aforesaid way, the both sides of briquetting are fixed with the guide lugs that has pilot hole, and described guide post slides and is inserted in the pilot hole.

As the further qualification to the utility model, when positioner positioned pre-assembled vehicle evaporator core and ear shape plate, described positioner and vehicle expansion core body sidewall were gnawed and are closed.

As the qualification to the utility model, described cylinder is fixedly installed on the top of gripper shoe, and the clutch end of cylinder connects the below that gripper shoe extends to gripper shoe.

Adopt as above technical scheme, its effect is following:

1, through positioner vehicle evaporator core and ear shape plate are positioned after; Clutch end drive briquetting with cylinder carries out pressing to both; Avoided the knocking of ear shape plate, thereby avoided influence, simultaneously follow-up welding quality; Owing to only need the one step press can be qualified, shortened and knocked the time that ear shape plate is lost;

2, the briquetting bottom surface has the shape that matches with ear shape plate upper surface, has reduced the appearance effects that pressing caused of briquetting to ear shape plate to greatest extent, has reduced the stress deformation of pressing process middle ear shape plate;

3, adopt guide post and briquetting to be slidingly matched, can avoid the stressed back of briquetting unstability for it provides reliable supporting, guiding in the process that briquetting presses down;

4, adopt the guide lugs of briquetting both sides to cooperate with guide post, have simple in structure, the characteristics of support reliable and stable;

5, the core body sidewall of positioner and vehicle evaporimeter is gnawed and is closed, and makes a plurality of directions of vehicle expansion core body sidewall be restricted effect simultaneously, helps quick location;

6, cylinder is placed the top of support portion, the clutch end of cylinder connects the below that extends to gripper shoe, can reduce the length of support, reduces this device occupation space.

In sum, adopt the technical scheme of the utility model, can effectively avoid press-fiting the generation of process middle ear shape plate metaboly, effectively raise the performance of evaporator core, improved the packaging efficiency of ear shape plate and evaporator core.
