Description

Technical Field

[0001] The utility model belongs to the technical field of automobile manufacturing, and more specifically, particularly relates to a front crossbeam inspection tool for an automobile. Background Art

[0002] The automobile frame is composed of longitudinal beams and cross beams. The cross beams are divided into front cross beams and rear cross beams. The cross beams are made separately. When the front cross beam of the automobile is made, a front cross beam inspection fixture is needed to inspect the production quality of the front cross beam. The staff installs the front cross beam on the inspection fixture, and the inspection component inspects the front cross beam.

[0003] According to the utility model disclosed in the application number 201921457000.9, a kind of inspection tool for automobile front cross beam includes a support, a detection plate, a fastening device and an adjusting device, wherein the fastening device is installed at the upper end of the detection plate, the adjusting device is installed at the bottom end of the support, the support and the detection plate are fixedly connected, and the fastening device includes a threaded rod, the outer surface of the threaded rod is sleeved with a threaded sleeve, one end of the threaded rod is fixedly installed with a fixed seat, both sides of the fixed seat are fixedly installed with a reinforcing rod, and the end of the reinforcing rod away from the fixed seat is fixedly installed with a chuck. The utility model improves the detection accuracy by providing a fastening device, avoids the situation that the position of the front cross beam is offset during the detection process, resulting in the detection result being affected, and by providing an adjusting device, it is convenient to adjust the angle of the detection plate according to the usage habits of different people, so that people can operate more comfortably when detecting the front cross beam, and improve the detection efficiency to a certain extent.

[0004] Based on the above, the existing front beam inspection fixture generally clamps the beam through the clamping block sliding structure, and then presses the beam through the pressure block to ensure the stability of the beam on the inspection fixture. Therefore, when installing the beam on the inspection fixture, the staff needs to first operate the pressure block to press the beam, and then operate the clamping block to slide and clamp the beam. When disassembling, it is necessary to first operate the pressure block and then the clamping block, and the operation steps are cumbersome. Utility Model Content

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model adopts an extrusion rotation mechanism, which enables a worker to twist the clamping screw to rotate and drive the clamping block to slide, and the clamping block slides to clamp the front cross beam.
