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....
