A building-block structure checking tool specially used for testing vehicle bottom side longitudinal beam assembly

Abstract

The invention belongs to the technical field of detection devices for automobile research and development, in particular to a building-block detecting tool special for detecting a longitudinal beam assembly on the bottom side of a vehicle. According to the building-block detecting tool special for detecting the longitudinal beam assembly on the bottom side of the vehicle, a plurality of supporting mechanisms, a plurality of positioning mechanisms, a plurality of hole site detecting mechanisms, a plurality of go-no go fixed gauges and a plurality of leveling gauges are arranged on a base, and the go-no go fixed gauges and the leveling gauges are installed on the base through corresponding turnover plate mechanisms or corresponding sliding rail mechanisms respectively. According to the structure of each sliding rail mechanism, a sliding rail base plate is fixed to the upper portion of an I-shaped support assembly, two parallel sliding rails are installed on the sliding rail base plate, one positioning plate is installed on the sliding rails through a sliding block below the positioning plate, and two or more leveling gauges are fixed to the positioning plate. By the adoption of the sliding rail mechanisms, the defects that due to the fact that multiple turnover mechanisms are arranged on a large detecting tool, operation is complex, the precision is poor after long-term use, the part detecting efficiency is low are overcome. The building-block detecting tool special for detecting the longitudinal beam assembly on the bottom side of the vehicle has the advantages that the number of parts is small, the overall machining is easy and convenient, and the safety and reliability are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of testing equipment for automobile research and development, in particular to a building block structure testing tool specially used for testing vehicle bottom side longitudinal beam assemblies. Background technique [0002] After the welding of each assembly that constitutes the automobile body is completed, it needs to be measured on the corresponding inspection tool to judge whether the deviation between the welded parts and the design requirements is within the tolerance value, and whether the welded parts are qualified. It is said that the inspection tool is a special inspection equipment for measuring and evaluating the dimensional quality of parts, and plays a non-negligible role in the quality control of part sample approval and mass production. [0003] In the prior art, the inspection tool for detecting the side rail assembly of the vehicle bottom usually includes a base plate, on which various ty...

Problems solved by technology

[0004] In the manufacture of existing large-scale inspection fixtures, the brackets are generally used in the welding process. This process has a long manufacturing cycle, the manufactured brackets are heavy, and the stress is large, resulting in poor stability and low precision, which greatly reduces the service life of the inspection fixtures; In the structure of the inspection fixture, the turning mechanism is very useful, but the existing turning mechanism is not efficient in use, and there are many steps to operate, so it is not suitable for large-scale inspection fixtures with many inspection requirements, complex structure and heavy weight. The mechanism is mostly composed of a base, a backing plate, a sealing plate, a positioning plate, and a positioning pin. When the weight of the detection block to be connected is heavy, it is found that the stability of the mechanism carrying heavy objects is poor, which affects the detection accuracy; in addition, zero The hole position detection of components requires a special hole position detection mechanism. The detection pin and the marking pin are indispensable in the use of the hole position detection mechanism. The existing hole position detection mechanism needs to use two pins for the same hole. It not only increases the cost, but also greatly increases the degree of difficulty of the operator
