Differential shell detection auxiliary tool

Abstract

A differential shell detection auxiliary tool comprises a base, a U-shaped positioning block assembly, a front V-shaped base assembly, a rear V-shaped base assembly, an angular device assembly, a positioning bolt and a fastening bolt, wherein the base is fixed on a three-coordinate detection table top, the U-shaped positioning block assembly is fixed on the base through positioning bolts, the front V-shaped base assembly and the rear V-shaped base assembly are fixed on the base through fastening bolts and located in the U-shaped positioning block assembly, the angular device assembly is installed on the front V-shaped base assembly, and a differential shell is installed on the front V-shaped base assembly and the rear V-shaped base assembly. According to the tool, N workpieces to be detected of the same variety can be rapidly placed at detected positions, and the positions are constant; effective measurement space is reserved for detection probes as much as possible, and direct starting and running of an automatic measurement program are achieved; the detection efficiency is high, and batch detection can be realized; and by replacing workpiece positioning elements, automatic measurement of various differential shells or various rotary parts of various types can be realized, and the application adaptability is wide.

Description

technical field [0001] The invention belongs to the technical field of auto parts detection, and in particular relates to an auxiliary detection tool for a differential case. Background technique [0002] With the continuous development of the automobile industry, the market has higher and higher requirements for the quality of auto parts, and the competition is becoming increasingly fierce. The testing level and efficiency of auto parts play an important role in the quality of the car. The quality of the differential housing The inspection is an important link to enhance product competitiveness. Existing detection methods are increasingly unsuitable for the increasing detection of vehicle axles and the requirements for quickly and timely providing the basis for optimizing process parameters for the production site. It is necessary to seek a detection tool with high efficiency, reliability, wide applicability, and stable state of the workpiece under test. [0003] Such as ...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 shown, where figure 1 (a) is support mode 1, where figure 1 (b) is the second support method, which is the support and attitude of the existing universal tool when detecting the differential case. This method has the following problems: 1. The original support occupies the measurement space, and the measurement probe cannot reach the effective position 2. The existing various support methods cannot realize all the inspection items at one time; 3. The initial placement positions of the N tested parts are inconsistent, and the automatic measurement program cannot be run, and points can only be collected manually Measurement requires separate operations for each measurement item, the detection data is not systematic, and data collection and statistical analysis is inconvenient; 4. The single-piece detection time period is long, the equipment utilization rate is low, and labor is consumed, so batch and rapid detection cannot be realized. Detrimental to real-time control monitoring of quality
