Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile manufacturing, and specifically relates to a hole position detection device of a commercial vehicle rear suspension support assembly. BACKGROUND

[0002] As shown in Figure 4 , Figure 5 , Figure 6 , Figure 7 The commercial vehicle rear suspension support assembly mainly comprises left rear suspension support assembly A, right rear suspension support assembly B and rear suspension support assembly piece C symmetrically arranged at the bottom of the cab, and the structure of the commercial vehicle rear suspension support assembly comprises U-shaped body D, the web of the U-shaped body D is formed into first flat plate E with a higher position and second flat plate F with a lower position through Z-shaped bending plate, and the first flat plate E and the second flat plate F are integrally formed through inclined transition. The side surface of the U-shaped body D is welded and connected with oil pump mounting L-shaped bracket one J of the left rear suspension support assembly A and oil pump mounting L-shaped bracket two J1 of the right rear suspension support assembly B, four vertical mounting holes G are arranged on the first flat plate E, and six transition connecting holes K are further arranged on the first flat plate E. The four vertical mounting holes G of the first flat plate E and the two side surface mounting holes H of the second flat plate F have higher position degree requirements.

[0003] According to the technical requirements of the product, firstly, the four vertical mounting holes G need to meet the installation requirements to ensure that the plane of the first flat plate E of the U-shaped body D is installed in place; meanwhile, the upper planes of the oil pump mounting L-shaped bracket one J and the oil pump mounting L-shaped bracket two J1 need to be kept parallel with the bottom surfaces of the four vertical mounting holes G and the six transition connecting holes K, and the upper plane mounting holes of the oil pump mounting L-shaped bracket one J and the oil pump mounting L-shaped bracket two J1 need to ensure the position degree with the four vertical mounting holes G and the six transition connecting holes K of the first flat plate E to ensure that the oil pump mounting L-shaped bracket one J and the oil pump mounting L-shaped bracket two J1 are installed in place; secondly, the two side surface mounting holes H at the second flat plate F need to ensure the position degree with the four vertical mounting holes G and the six transition connecting holes K of the first flat plate E; otherwise, the product is unqualified.

[0004] In the production process, the oil pump mounting L-shaped bracket one J and the oil pump mounting L-shaped bracket two J1 are fixed with the U-shaped body D through welding, and the welding position is just at the variable cross-section of the U-shaped body D, so that deformation and other conditions are more likely to occur; the distance between the two side surface mounting holes H at the second flat plate F and the four vertical mounting holes G and the six transition connecting holes K of the first flat plate E is far, and the sheet metal is prone to rebound when the rear suspension support assembly is formed, so that the position degree of the two side surface mounting holes H at the second flat plate F is poor, which leads to the difficulty in smooth installation of the product with the frame after the product is shipped, and the product qualification rate is low.

[0005] Therefore, for multiple holes of multiple parts of the commercial vehicle rear suspension support assembly, multiple measurements need to be performed, which is time-consuming, and since the commercial vehicle rear suspension support assembly is irregular, large in size and heavy in weight, it is inconvenient to directly measure by using a caliper, but detection instruments such as height measuring instruments are used to detect each hole position, which requires relatively high skills of the inspectors and is limited by inconvenient detection, and cannot meet the needs of large-scale production.
