Description

Automobile outer cover fender checking fixture

Technical Field

The utility model relates to the technical field of automobile manufacturing, in particular to an automobile outer cover fender checking fixture.

Background

With the fact that China becomes the first country of world automobile production and sale, the automobile insurance quantity is expected to be the first world, but the development of high-grade automobiles is not matched with the first country of world production and sale, and the development of high-grade automobiles is in great relation with the development lag of automobile mold industry known as the "automobile industry mother".

The automobile mould is a mould applied to the automobile field, and more than 90% of parts in automobile production need to be formed by the mould. The automobile body mold, especially the large and medium covering part mold, is an important component of automobile body manufacturing technology and a key link for forming the autonomous development capacity of automobiles.

The design and manufacture of the covering part die of the car in the automobile die have the characteristics of high difficulty and high quality and precision requirements, so that the die process, the design, manufacture and debugging levels are improved, and the key effect is played on the development of the future automobile die.

The detection of stamping parts mainly adopts two measurement modes, namely manual measurement of a detection tool and automatic measurement of three coordinates at present. The selection of the positioning reference during the measurement is particularly important. The reasonable and effective benchmark determines the reasonability and effectiveness of the detection scheme. The design and manufacture of the covering part die of the car in the automobile die have the characteristics of high difficulty and high quality and precision requirements, so that the die technology, design, manufacture and debugging levels are improved, and the critical effect is played on the development of the future automobile die. In the prior art, the fender checking fixture usually selects a side flanging face as a C reference and a side flanging outline as a B reference for positioning, and the precision is difficult to guarantee during actual production and manufacturing. In the detection scheme, the reference B is defined as a reference for main positioning and controlling X-axis translation and Z-axis rotation of the part, and the reference C is defined as a reference for auxiliary positioning and controlling Z-axis translation of the part. In the early pilot stage, the B benchmark requires manual trimming. The inaccuracy of the reference results in that the report of the qualified rate of the part detection cannot accurately reflect the real qualified rate of the part. In addition, in the mould manufacturing rectification process, rectification cannot be performed according to the detection data of the detection tool, and the measurement data loses the referential property. Thereby increasing the mold manufacturing cycle and reducing the efficiency.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems in the prior art, the utility model aims to provide an automobile outer cover fender testing fixture.

The utility model discloses an automobile outer cover fender checking fixture, which comprises a base plate, a checking fixture body arranged on the base plate and a detection block matched with the checking fixture body; a first C datum point and a second C datum point are arranged on the side turning side of the gauge body; a first datum point B and a second datum point B are arranged on the side flanging outline of the gauge body; the fixture body is further provided with a CH hole reference.

Wherein the CH holes are two in number.

The CH hole reference is arranged on the plane of the checking fixture body.

The base plate is provided with a plurality of supporting columns, and the checking fixture body is arranged on the supporting columns and fixed through a clamping device.

Wherein, the detection block is a plurality of blocks.

Compared with the prior art, the automobile outer cover fender checking fixture has the following beneficial effects:

(1) the debugging efficiency of the site worker mold is improved;

(2) the mould rectification cycle is shortened, and effective rectification data is provided for each rectification;

(3) the early EP pilot stage, (hand finishing) can provide parts of higher yield.

Detailed Description

The following description of the inventive outer cover fender test device will be provided in conjunction with specific embodiments to help those skilled in the art to more fully, accurately and deeply understand the technical solution of the present invention.

Example 1

As shown in fig. 1, the automobile outer cover fender testing tool of the present embodiment includes a base plate 50, a testing tool body 60 disposed on the base plate 50, and a detection block engaged with the testing tool body 60. A first C datum point 10 and a second C datum point 20 are arranged on the side edge turning surface of the gauge body 60; the side flanging outline of the gauge body 60 is provided with a first reference point B and a second reference point B. The gauge body 60 is further provided with CH hole references 70(CH holes, i.e. english translation of checkhole), preferably, the number of CH hole references 70 is two, and preferably, the CH hole references 70 are provided on a surface with a small curvature of the gauge body 60, for example, may be provided on a plane of the gauge body 60. A plurality of support columns are arranged on the base plate 50, and the inspection device body 60 is arranged on the support columns and fixed through a clamping device 52. The number of the detection blocks is preferably plural, and for example, the detection block 51, the detection block 80, and the detection block 81 are provided in the figure.

In the automobile outer cover fender checking fixture, the CH hole 70 is added to be used as a temporary reference, the 70CH hole is punched through an OP10 process in the die debugging process, and the checking fixture is correspondingly defined as the temporary reference hole according to the position coordinate. The process comprises the following steps of inputting the position of a CH hole 70 of a die design drawing into a design drawing of a checking fixture, and processing the CH hole 70 of a manufacturing drawing to be used as a reference of the checking fixture. After fabrication is complete, three-coordinate measurements are required to determine the accuracy of the hole locations. Adopt the outer covering piece fender of car of this embodiment to examine utensil is favorable to improving the fender precision, shortens the mould and reorganizes the cycle to can provide effectual reorganization data for rectifying at every turn. In the early EP pilot stage, (hand finishing) can provide parts of higher yield.

It is obvious to those skilled in the art that the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the specific implementation of the present invention is not limited by the above-mentioned manner, and various insubstantial modifications made by the method concept and technical scheme of the present invention are within the protection scope of the present invention.
