Automobile testing fixture quantitatively-adjustable movable reference mechanism and adjusting method

Abstract

The invention discloses an automobile testing fixture quantitatively-adjustable movable reference mechanism and an adjusting method. The mechanism comprises a reference pin installation base which comprises a fixed pedestal and an installation column which is located on the fixed pedestal and is integrally connected with the fixed pedestal, wherein the side surface of the fixed pedestal is provided with a chuck assembly connecting piece; a reference pin which is mounted at the mounting column; and a chuck assembly which comprises a chuck mounting base, a chuck and a chuck driving mechanism, wherein the chuck mounting base is connected with the chuck assembly connecting piece, the chuck is located above the chuck mounting base and connected with the chuck mounting base through the chuck driving mechanism, and the chuck driving mechanism is mounted at the vertical extending part of the chuck mounting base. The chuck driving mechanism comprises a driving rod and a driving disc; a vertically extending driving rod mounting hole and a driving disc mounting notch communicated with the driving rod mounting hole are formed in the vertically extending part of the chuck mounting base; scalesfor recording circumferential angle values are marked on the circumference of the driving disc; and an indicator pointing to the scales is arranged on the chuck installation base.

Description

technical field [0001] The invention relates to the field of a movable reference mechanism of an automobile inspection tool, and more specifically relates to a quantitatively adjustable movable reference mechanism and an adjustment method of an automobile inspection tool. Background technique [0002] Automobile inspection tool is an indispensable inspection tool in the automobile industry, and the benchmark is the most important part of the inspection tool. In the past, the clamping point on the part was composed of two parts: the traditional long-arm clamp and the fixed reference. Due to the separation of the two, the installation position and angle of the compactor have a great influence on the stability of the part, and there will be interference with the body of the inspection tool or the workpiece of the part, making it unusable. Moreover, the traditional benchmarks are fixed, and the correct value cannot be obtained from the springback measurement of the parts. Theref...

[0002] Automobile inspection tool is an indispensable inspection tool in the automobile industry, and the benchmark is the most important part of the inspection tool. In the past, the clamping point on the part was composed of two parts: the traditional long-arm clamp and the fixed reference. Due to the separation of the two, the installation position and angle of the compactor have a great influence on the stability of the part, and there will be interference with the body of the inspection tool or the workpiece of the part and cannot be used.

Moreover, the traditional benchmarks are fixed, and the correct value cannot be obtained from the springback measurement of the parts. Therefore, it is urgent to design a movable benchmark mechanism that can be quantitatively adjusted.
