Embodiment Construction

[0040] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0041] The disclosure provides a positioning jig, which can be used to position the host of electronic devices such as mobile phones and tablets during processing. The X-axis of the positioning jig" and the "Y-axis of the positioning jig" are perpendicular to each other and form a plane perpendicular to the Z-axis. The left and right directions are taken as an example for description....

Abstract

The invention relates to a positioning jig. The positioning jig comprises a pressing assembly, wherein the pressing assembly is used for pressing a workpiece to be processed in the Z-axis direction ofthe positioning jig, the pressing assembly comprises a plurality of pressing claws and a plurality of elastic parts, the plurality of elastic parts are arranged corresponding to the plurality of pressing claws and apply elastic force in the Z-axis direction to the plurality of pressing claws, and the plurality of pressing claws are used for elastically pressing the workpiece to be processed. Wheneach pressing claw is in press fit with the corresponding part of the workpiece to be processed, the elastic parts have the elastic force and displacement in the Z-axis direction, the pressing clawscorresponding to the elastic parts have different displacement relative to a cross beam, the pressing claws make contact with the parts of the workpiece to be processed, and it is guaranteed that allthe parts of the workpiece to be processed are pressed in place, so that deformation caused by large press fit state difference among the different parts of the workpiece to be processed is avoided.

Description

technical field [0001] The present disclosure relates to the technical field of mechanical processing, in particular to a positioning jig. Background technique [0002] Such as figure 1 As shown, in the process of processing the mainframe of electronic equipment such as mobile phones and tablets, the middle plate structure 100 is first formed through the die-casting process, and then the middle plate structure 100 is welded to the frame 200, and then the positioning jig of the processing machine tool is used to form the middle plate structure. The integral part formed by 100 and frame 200 is positioned along the Z-axis direction of the machine tool. [0003] Such as figure 2 As shown, the existing positioning jig has a jig body 600 , a moving beam 300 , pressing jaws 400 and supporting columns 500 , wherein there is one pressing jaw 400 and four supporting columns 500 . The beam 300 is installed on the jig body 600 and can move along the Z-axis direction. The support co...
