[0002] Textile machines, also known as spinning machines, looms, cotton spinning machines, etc., were originally hand-operated looms. The term "textile machine" is a general term for the tools used to process raw materials such as thread, silk, and hemp into fabric. Examples include spinning wheels, spinning spools, and pedal looms, as well as modern mechanical looms and modern CNC automatic looms. The development of textile processes and equipment throughout history has been designed in response to textile raw materials. Therefore, raw materials play an important role in textile technology, and the crankshaft is an important component of a textile machine.

[0003] CNC milling machines are automatic machining equipment developed from general milling machines. The machining processes of the two are basically the same, and their structures are also somewhat similar. CNC milling machines are divided into two main categories: those without tool magazines and those with tool magazines. CNC milling machines with tool magazines are also called machining centers, and machining centers are needed in the turning process of crankshafts.

[0004] However, existing CNC machining centers are not convenient for installing and fixing crankshafts, which results in a lot of time being spent on crankshaft installation and disassembly. Furthermore, it is not convenient to collect waste materials, which leads to a large amount of waste materials being scattered inside or on the surface of the machining center, affecting the turning process.

The other end of the crankshaft is placed between the two first pressure rollers 32. Then, the mounting frame 35 is lowered by the lifting cylinder 34. The crankshaft end is fixed by the cooperation of the second pressure roller 36 and the first pressure roller 32. Then, the second baffle 5 is reset. During turning, the crankshaft is sprayed by the high-pressure nozzle 421, and the waste material is washed off and collected in the fixed seat 1. The first baffle 4 and the second baffle 5 block the waste material, reducing the splashing of waste material. This achieves the effect of making it easy for the CNC machining center to install and fix the crankshaft and to collect and process the waste material generated during processing.
