Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile assembly, and in particular relates to an assembly welding positioning system device for an automobile electric door column. Background Art
[0002] With the continuous development of the automobile industry, the types of automobiles have become rich and diverse, and the demand for modification has increased significantly, gradually forming a market response model for small-batch, multi-variety and customized automobiles.
[0003] The electric automation control of the car front door is one of the forms of car modification. The positioning of the column is very important, which directly affects the functional requirements of smooth opening and closing of the electric door and the aesthetic requirements of uniform surrounding gaps. This requires effective and stable control of the column assembly and welding.
[0004] The original tooling for the assembly and welding positioning of the electric front door pillar of the automobile uses the mounting holes of the upper and lower flip brackets of the electric door on the inner plate of the B-pillar as the positioning holes and the mounting surfaces of the sealing strips of the A and B-pillars as the reference surfaces, resulting in a large size and heavy weight of the tooling. During assembly and welding, two operators lift the tooling onto the front door frame, position and fix it, and then install the electric front door pillar onto the tooling for CO2 welding. After welding, the two operators pull out the positioning pins, remove the tooling from the inside of the car body, and lift the tooling out of the car body. The steps are relatively cumbersome. At the same time, due to the long dimensional chain links of the entire positioning system, the dimensional accuracy of the parts manufacturing cannot be effectively controlled, and manual measurement and verification of key dimensions are required, and precise correction and rework are required.
[0005] In actual production, the jigs and fixtures manufactured using the above traditional model have problems such as high cost and poor versatility, and are increasingly difficult to adapt to the flexible and changeable small-batch, multi-variety, and customized modification production needs. In addition, in order to ensure the positioning accuracy of the product, the traditional positioning jigs and fixtures have high structural rigidity requirements, resulting in heavy jigs and fixtures. When used in the modified production method, it is inconvenient for workers to use and the ergonomics is poor.
[0006] The modification and production of automobile electric front doors not only requires smooth door opening and closing and uniform gaps, but also requires low investment and fast response to the market. Traditional tooling and fixtures can no longer meet the requirements of low cost, high efficiency and high quality. A new type of tooling with low cost, simple manufacturing and easy use is urgently needed to meet the modification production and better adapt to market demand. Therefore, a new automobile electric door column assembly welding positioning system device is proposed to meet the design and assembly requirements. Utility Model Content
[0007] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a vehicle electric door column assembly welding positioning system device, which is used for modification production in the body-in-white assembly state, to ensure that the vehicle electric front door column assembly welding positioning is reliable, and the dimensional accuracy and consistency meet the design specifications and process control requirements, without the need for manual re-measurement, verification, correction and rework.
[0008] The utility model provides an automobile electric door column assembly welding positioning system device, comprising a tool body, a positioning pin and a limiting block, wherein the positioning pin comprises a main positioning pin and an auxiliary positioning pin for positioning the tool body and a door frame in the X and Z directions, the main positioning pin is installed on a main positioning hole of a front door frame assembly, the auxiliary positioning pin is installed on a fender mounting hole on the front door frame, the main positioning pin on the tool for positioning the electric front door column assembly in the Z direction is installed on the positioning hole for positioning on the electric front door column, the forming surface of the electric front door column assembly is attached to the positioning surface in the X and Y directions of the tool, the limiting block in the Y direction of the tool is attached to the sealing strip mounting surface of the front door frame, and the clamp on the tool body is connected to the electric front door column assembly and the sealing strip mounting surface of the front door frame in the Y direction in a sequential order.
[0009] For the directions of the X, Y, and Z axes in this application, please refer to Figure 1 .
[0010] As a further technical solution of the utility model, the main locating pins in the Z direction, the locating blocks in the X direction and the locating blocks in the Y direction of the electric front door column assembly are arranged on the tooling, and the locating holes for positioning are installed on the parts of the electric front door column assembly. The clamps on the tooling body are connected to the forming surfaces of the electric front door column assembly in the X and Y directions.
[0011] Furthermore, the tooling body is an integral spatial truss structure, the main reference hole on the front door frame and the fender mounting hole are the X and Z direction references, the main locating pin is installed on the main locating hole of the front door frame, the auxiliary locating pin is installed on the fender mounting hole on the front door frame, and the clamp on the tooling body is connected to the Y direction of the front door frame sealing strip mounting surface.
[0012] Furthermore, a plurality of weight-reducing through holes are evenly arranged on the tool body.
[0013] The advantage of the utility model is that it adopts a spatial truss structure with sheet metal bending parts as the main body to meet the requirements of lightweight and low cost. At the same time, since the positioning of the tooling itself and the vehicle body assembly and the positioning of the workpiece on the tooling are all designed and arranged on one body, the dimensional chain links of product parts and tooling manufacturing accuracy are reduced. Compared with traditional tooling, the overall tooling volume is significantly reduced, and the weight is reduced from the original 25Kg to 6Kg, making it more flexible and convenient for workers to operate.
