Description

Automobile headlamp assembling and positioning tool

Technical Field

The utility model belongs to the technical field of the automobile production equipment, specifically speaking, the utility model relates to an automobile headlamp positioning tool.

Background

The automobile headlamp is usually matched with 3 assemblies of a front protection upper decorative plate, a front bumper and a fender, clearance surface difference between the automobile headlamp and peripheral parts needs to be considered in the assembling process, the matching key point of each host factory is also a difficult point, and the main matching key point is also one of the areas of primary attention of customers to appearance.

One of the very common positioning designs of automotive headlamps is that the a datum controls the Z direction (2 at the headlamp beam, 1 at the fender, 1 at the headlamp lower bracket on the water tank vertical plate), the B datum controls the Y direction (the positioning hole on the fender and the headlamp lower mounting point at the reinforcing beam outer plate on the front wheel cover), and the C datum controls the X direction and other auxiliary positioning references (close to the fender). The assembly positioning mode is close to the rear end, the matching of the headlamp and the fender can be well controlled, however, the effect is very poor and the consistency is also poor when the headlamp is matched with the front protection Y-direction gap.

At present, a host factory mostly adopts a headlamp Z-direction mounting point to be designed into a through hole, and the matching effect of the headlamp and a front protective Y-direction gap is improved by adjusting the rotation of the headlamp at a final assembly adjusting station. At the same time, the following disadvantages are brought:

1. the final assembly stations are adjusted on line, full-time stations are added to the production line, and the labor cost is increased;

2. the manual adjustment efficiency is low, and the requirements of quick and efficient production rhythm cannot be met;

3. the consistency is poor, basically 100% of the consistency needs to be adjusted, and production staff have great complaints;

5. the requirements of users on the appearance of the appearance with higher and higher beauty and quality cannot be met.

Detailed Description

The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to understand more completely, accurately and deeply the conception and technical solution of the present invention, and to facilitate its implementation.

It should be noted that, in the following embodiments, the "first" and "second" do not represent an absolute distinction relationship in structure and/or function, nor represent a sequential execution order, but merely for convenience of description.

As shown in fig. 1 to 5, the utility model provides an automobile headlamp positioning tool, including frock main part 2 and set up first locating pin, second locating pin and analog block 4 on frock main part 2, automobile body front end frame has and lets first locating pin and second locating pin two locating holes 1 that insert respectively, and analog block 4 sets up two and two analog block 4 and is connected with the relative both ends of frock main part 2 respectively.

Specifically, as shown in fig. 1 to 5, the tool main body 2 has a certain length, the first positioning pin and the second positioning pin are respectively and fixedly disposed at two opposite ends of the tool main body 2 in the length direction, the axis of the first positioning pin is parallel to the axis of the second positioning pin, and the axes of the first positioning pin and the second positioning pin are perpendicular to the length direction of the tool main body 2.
