Wheel flaw detector auxiliary device based on gear linkage principle

Abstract

The invention relates to the technical field of automobile detection auxiliary equipment, provides a wheel flaw detector auxiliary device based on a gear linkage principle. The auxiliary device comprises a bottom plate; a movable screw group is connected to the front side of the bottom plate; a fixed screw is connected to the movable screw group and penetrates the bottom plate; and the bottom of the fixed screw is fixedly connected with a driven gear. The central axes of the bottom plate, the movable screw group and the fixed screw are arranged at the same straight line. Four limiting seats are fixedly connected to the outer side of the bottom plate. According to the auxiliary device, when the movable screw group moves upward, the distance between clamp blocks is reduced to clamp a tyre; when the movable screw group moves downward, the distance between clamp blocks is increased to take out the tyre after detection completion. On the basis of the structure and process, the tyre can be clamped and fixed by the device; the operation becomes convenient and thus certain working time is saved; the accuracy of the detection result is improved and the work efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of automobile detection auxiliary equipment, in particular to an auxiliary device for a wheel flaw detector based on the principle of gear linkage. Background technique [0002] When using a flaw detector to detect tires, it is necessary to ensure that the position of the tire remains unchanged during the detection process. If the position of the tire changes or shifts during the detection process, the position of the detection point may change, and the operator needs to re-adjust the tire. Positioning and re-calibrating the detection points will seriously affect the progress of the detection work and prolong the detection cycle. At the same time, if the tire deflects, it may affect the accuracy of the detection results, making the authenticity of the detection data difficult big error.

[0002] When using a flaw detector to detect tires, it is necessary to ensure that the position of the tire remains unchanged during the detection process. If the position of the tire changes or shifts during the detection process, the position of the detection point may change, and the operator needs to re-adjust the tire. Positioning and re-calibrating the detection points will seriously affect the progress of the detection work and prolong the detection cycle. At the same time, if the tire deflects, it may affect the accuracy of the detection results, making the authenticity of the detection data difficult big error

[0003] At the same time, the existing jaw-type tire clamping device generally needs to change the rotation direction of the main shaft to tighten or loosen the jaws. During the detection process, it is necessary to frequently change the rotation direction of the main shaft, which may Lead to increased wear of the spindle, reducing the service life of the unit
