Planeness detection device

Abstract

The invention discloses a planeness detection device, which comprises a detection frame and two support seats of the same height, wherein the detection frame comprises a cross beam and at least one detection arm; the detection arm is vertically mounted on the cross beam; support planes are arranged at the upper parts of the support seats; the two ends of the cross beam of the detection frame are overlapped on the support planes of the support seats; the planeness detection device further comprises a detection platform; the detection platform is provided with a bearing surface for a flat plate work piece; and the lower ends of the support seats are fixed on the bearing surface of the detection platform. The planeness detection device provided by the invention has the advantages that through measuring the value of a clearance between the lower end surface of the detection arm and a mounting plane of the flat plate work piece, the planeness of the mounting plane of the flat plate work piece can be detected simply, conveniently and rapidly; and meanwhile, the assembly quality of other work pieces mounted on the mounting plane can be detected, and assembly adjustment can be made at any time according to detection situations, thereby improving the quality and the efficiency of assembly production of the equipment.

Description

technical field [0001] The invention relates to workpiece detection technology, in particular to a flatness detection device. Background technique [0002] In the equipment assembly process, especially when it comes to the assembly of larger flat workpieces, the flatness of the installation plane of the flat workpieces directly affects the quality and efficiency of the assembly production of the entire equipment. When the flatness exceeds the tolerance range of the design, it may even cause the equipment to be unable to be assembled normally, seriously reducing the quality and efficiency of equipment production. [0003] For example, in the assembly of the locomotive underframe, the underframe of the locomotive is equipped with a corbel, which is usually a plate beam structure with a large external dimension. One plane of the corbel is the second series installation plane, and the shock absorber of the locomotive is installed on the second series installation plane. system....

AI Technical Summary

Problems solved by technology

When using the reverse assembly process to assemble the locomotive underframe, the second-series installation plane on the corbel faces upward, and the flatness of the second-series installation plane of the corbel can only be positioned through the other side of the corbel, because the corbel cannot be observed during the assembly process Therefore, the installation quality of the secondary springs of the shock absorption system cannot be guaranteed, and in the case of poor flatness of the secondary installation plane, the secondary springs cannot be assembled at all.

[0004] In the actual assembly process, the precision level can be used to detect the flatness of the installation plane of the second series. However, since the precision level requires more detection points, it needs to be repeatedly adjusted and measured. The detection is complicated and the detection time is long, which will also reduce the cost of equipment assembly and production. quality and efficiency
