Description

Technical Field

[0001] The utility model relates to the technical field of automobile body testing, in particular to a connecting tooling for body testing. Background Art

[0002] At present, when conducting body stiffness and strength tests (such as bending and torsion stiffness, body dent resistance, local strength), the body needs to be fixed and supported on the test bench, and then the loading test is carried out.

[0003] The current industry - wide general fixing method is that the front connection installation point is the front shock absorber installation hole, and the rear connection installation point is the rear shock absorber installation part; however, there are no rear shock absorber installation holes on the bodies of some vehicles. Without damaging the body, it is necessary to consider the installation, connection and fixation between the body and the test bench support frame; due to the differences in the connection and fixation methods between the body - in - white and the test bench, the current connection methods have low versatility and strength differences.

[0004] For example, a clamping tooling for automobile axle durability test disclosed in Patent CN209085937U includes: a bottom plate and a plurality of mounting panels. The plurality of mounting panels are arranged on the bottom plate and are respectively provided with different types of axle mounting holes, and the axle mounting holes are connected to the axle through bolts; the plurality of mounting panels are sequentially connected on the bottom plate and form a closed - loop structure; it cannot be applied to other size - specification structures and has poor versatility.

[0005] Aiming at the deficiencies of the prior art, the utility model provides a connecting tooling for body testing to achieve the purpose of strong versatility and easy use.

[0006] In order to solve the above - mentioned technical problems, the technical solution adopted by the utility model is as follows:

[0007] The connecting tooling for body testing is a U - shaped connecting piece, which includes a test bench connecting plate, a connecting plate on one side of the body longitudinal beam and a connecting plate on the other side of the body longitudinal beam. The connecting plate on one side of the body longitudinal beam and the connecting plate on the other side of the body longitudinal beam are oppositely arranged on both sides of one side of the test bench connecting plate, and a set of connecting threaded holes are provided on both the connecting plate on one side of the body longitudinal beam and the connecting plate on the other side of the body longitudinal beam.

[0008] Furthermore:

[0009] The test bench connecting plate, the connecting plate on one side of the body longitudinal beam and the connecting plate on the other side of the body longitudinal beam are of an integral structure.

[0010] The connecting plate on one side of the body longitudinal beam and the connecting plate on the other side of the body longitudinal beam are symmetrically arranged.

[0011] A set of test bench support rod connecting holes are provided on the test bench connecting plate.

[0012] On both the connecting plates on one side of the vehicle body longitudinal beam and the connecting plates on the other side of the vehicle body longitudinal beam, corresponding connecting through holes are provided.

[0013] The set of connecting threaded holes are multiple rows of holes arranged in the height direction.

[0014] The connecting through holes and the connecting threaded holes are arranged side by side.

[0015] Compared with the prior art, the present utility model has the following advantages:

[0016] The structure of the vehicle body test connection tooling is reasonably designed. The connection and fixation of the vehicle body tail can be realized by tightening the longitudinal beam with bolts. It has strong practicability, a wide application range, and can realize the fixed connection test of different vehicle models or vehicle frames; and the structure is simple, easy to use, and the cost is relatively low.

[0021] The following further describes in detail the specific embodiments of the present utility model by describing the embodiments with reference to the drawings.

[0022] As Figure 1 shown, the vehicle body test connection tooling is a U-shaped connecting piece, which includes a test bench connecting plate 1, a connecting plate 2 on one side of the vehicle body longitudinal beam, and a connecting plate 3 on the other side of the vehicle body longitudinal beam.

[0023] The connecting plate 2 on one side of the vehicle body longitudinal beam and the connecting plate 3 on the other side of the vehicle body longitudinal beam are oppositely arranged on both sides of one side of the test bench connecting plate. A set of connecting threaded holes 5 are provided on both the connecting plate on one side of the vehicle body longitudinal beam and the connecting plate on the other side of the vehicle body longitudinal beam.
