Problems solved by technology

However, due to factors such as the cumulative tolerance of the previous process and the clamping of the operator, in addition, the position of the probe is still unstable due to the influence of the previous station, making it difficult to fully guarantee the accuracy of the 0.48mm depth of the reference plane as the detection point, which leads to The card holder and other parts of existing mobile phones and other products have obvious unevenness after being inserted into the card slot hole

Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0028] In this example, refer to figure 1 , figure 2 with image 3 , the method for processing side holes on arc-shaped...

Abstract

The invention discloses a method for machining a side hole in an arc-shaped face. The method comprises the following steps of determining the position of the to-be-machined side hole; firstly, conducting machining according to complete dimensions of the side hole, the length dimension and the width dimension of a carrying chute and one part of the depth dimension of the carrying chute, and reserving the remaining part of the depth dimension of the carrying chute; then determining the machining dimension of the reserved part of the carrying chute; and then machining the reserved part. According to the method for machining the side hole in the arc-shaped face, when the side hole is machined in the arc-shaped side face of an outer shell, one part of the carrying chute is machined in the first place, and the other part is reserved; in addition, the surface of the reserved part is of a plane structure; then, the remaining machining depth is searched for in the deep position through a probe with the plane as the datum; and then machining is conducted according to the depth value of the remaining part, thus the depth dimension, such as 0.48 mm, of the carrying chute is completely guaranteed, and after a clamping support or another part is inserted therein, the clamping support or another part can be matched with the outer shell perfectly.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for processing a side hole on a product with an arc-shaped side, such as processing a SIM card slot hole of a mobile phone shell with an arc-shaped edge. Background technique [0002] Many products have curved sides, such as mobile phones, cameras, etc., and holes on the sides of these products need to be processed, such as SIM card slot holes, expansion memory card slot holes, and so on. In addition to the accommodating hole of the main part of this type of card slot hole, in order to make the outer surface of the relevant card holder inserted into the slot hole flush with the product surface, brackets are usually provided on at least one side of the card slot hole, through the bracket Support the card holder so that the card holder neither protrudes from the product shell nor sinks into the card slot hole to form a depression, that is, it should not be to...
