Description

Technical Field

[0001] The utility model relates to the field of machining, in particular to a pen tube end face milling machine. Background Art

[0002] A touch pen is an auxiliary tool that facilitates users to use electronic devices. Generally, it includes a pen tube, a contact head and internal electronic components, wherein the contact head is installed at the tip of the pen tube. The pen tube is generally an injection molded part. During production, a sprue will be left at the end opposite to the tip. Therefore, the circumferential surface of one end of the pen tube opposite to the tip needs to be milled to remove the sprue and process corresponding structures to install or adapt other accessories (as Figure 8 shown, the pen tube 200 is the product before processing, and the pen tube 200' is the product after processing. The end to be processed is 201, the sprue is 202, and the end to be processed 201 becomes the finished end 201' after processing). However, the wall thickness of the circumferential surface of the pen tube is small and it is easy to deform. Therefore, when using a traditional numerical control lathe to mill the circumferential surface, when the milling feed rate is small during milling, although a high yield rate can be guaranteed, the production efficiency is low; when the milling feed rate is large during milling, the pen tube often becomes scrapped and the yield rate is low.

[0003] Therefore, it is necessary to design a pen tube end face milling machine to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pen tube end face milling machine, which can ensure both a high yield rate and a high production efficiency when machining the end face of the pen tube.

A support member for inserting into the pen tube to support the circumferential wall of the end to be processed of the pen tube is also arranged, which enhances the stiffness of the end to be processed of the pen tube, so that the circumferential wall of the end to be processed of the pen tube is not easily deformed during milling processing and can withstand a larger milling feed amount. Therefore, both a high qualified rate can be ensured and the production efficiency can be maintained at a high level.
