Detection device for positioning components and mobile phone casings

Abstract

The invention provides a positioning assembly and a detection device for a mobile phone shell. The positioning assembly comprises a first transmission shaft, a second transmission shaft, a positioningblock and a jackscrew, wherein one end of the second transmission shaft is connected with the first transmission shaft; the positioning block is connected with the other end of the second transmission shaft through the jackscrew; and when the first transmission shaft moves in the axial direction of the first transmission shaft or rotates around the axis of the first transmission shaft, the secondtransmission shaft moves in the radial direction of the first transmission shaft along with movement of the first transmission shaft, then the positioning block is used for positioning the mobile phone shell, and the positioning reliability and the detection accuracy of the mobile phone shell are improved.

Description

technical field [0001] The invention relates to the technical field of mobile phone housing positioning detection, in particular to a positioning component and a mobile phone housing detection device. Background technique [0002] At present, the process of mobile phone parts is complicated and there are many features. The 2D drawings are generally set according to the principle of four-sided centering. This requires us to measure the benchmark with reference to the benchmark center for detection. [0003] In the related technology, the general detection method is: when detecting the inner length and width, because the length is long, it is necessary to take multiple points, and then determine the center line according to the value, and then detect whether there is any deviation in each position according to the center line, which takes a long time , the error is large. At the same time, as to whether there is a deviation of the outer contour relative to the center line (wh...

At the same time, for the deviation of the outer contour relative to the center line (whether the outer contour is milled in place), it is necessary to convert the datum many times, and it is even impossible to detect
