Test tool for coating suspender

Abstract

The invention discloses a test tool for a coating suspender. The test tool comprises a bearing frame, a locking device, an elevating frame, a positioning plate and at least one positioning hole, the bearing frame is detachably fixed on a steel beam of a workshop, the elevating frame is connected to the bearing frame in an up-down sliding way, the locking device is detachably fixed to the lower portion of the elevating frame and is in locking connection with the bearing frame in an unlockable way, the positioning plate is detachably fixed on the elevating frame, the positioning holes are distributed in the positioning plate separately, each positioning hole corresponds to the position of a positioning pin of the suspender, and the positioning hole is plugged with the corresponding positioning pin in a releasable way. The test tool for the coating suspender is simple in structure, flexible and convenient to elevate, easy to operate, safe and reliable, the correction precision of the suspender can be guaranteed, the success rate of vehicle body handover is improved, and an operator of the test tool is safer.

Description

technical field [0001] The invention relates to the technical field of detection of an automobile painting spreader, in particular to a detection device of a painting spreader. Background technique [0002] like figure 1 As shown, the existing spreader and inspection tool in the painting workshop adopts a multi-point joint rotating arm structure, the lifting is controlled by a cylinder 15, and the frame uses a guide wheel 16 structure. This structure has the following problems: [0003] 1. The lifting of the frame of the spreader calibration tool is guided by the combination of 16 guide wheels, the support is thin, the overall shaking is large, and the accuracy is >5mm, which cannot guarantee the accuracy of the frame; [0004] 2. The part of the positioning pin inspection tool adopts a multi-point joint rotating arm structure. The joint part adopts the pin shaft to rotate, and the root shakes greatly. , resulting in a high rate of vehicle body handover failures; [0...

AI Technical Summary

Problems solved by technology

[0003] 1. The lifting of the frame of the spreader calibration tool is guided by the combination of 16 guide wheels, the support is thin, the overall shaking is large, and the accuracy is >5mm, which cannot guarantee the accuracy of the frame;

[0004] 2. The part of the positioning pin inspection tool adopts a multi-point joint rotating arm structure. The joint part adopts the pin shaft to rotate, and the root shakes greatly. , resulting in a high rate of vehicle body handover failures;

[0005] 3. The lifting adopts the cylinder 15 control method. It is difficult to control the lifting speed, and the output force of the cylinder is large. There are major safety risks such as extrusion for maintenance operators.
