Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a blower shaft swing arm. Background Technology

[0002] In existing machining processes, automated or semi-automated CNC machine tools are used, where materials are manually clamped onto the machine tool for processing. After processing, the machined parts or machine tool are manually cleaned using an air gun to remove metal filings or waste. In automated equipment processing, the air gun still needs to be held manually, which is time-consuming and labor-intensive, resulting in low automation. Furthermore, existing air guns are limited in function, only capable of spraying air, and their poor sealing leads to leaks over time, resulting in ineffective cleaning of the machine tool. To address this, the inventor designed a blowing shaft swing arm. This swing arm can automatically spray air or apply cutting fluid, while the blowing shaft can rotate and swing under external force, facilitating automated processing with automated equipment. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a blower shaft swing arm.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a blowing shaft swing arm, comprising a base and a blowing shaft, wherein a sleeve is formed at the top of the base, the sleeve being a hollow cavity structure with openings at both ends, a first bearing and a second bearing being respectively installed at the openings at both ends of the sleeve, an air pipe connector seat is provided on the base below the sleeve, an air pipe connector is installed on the air pipe connector seat, the output end of the air pipe connector passes through the blowing shaft sleeve from the outside to the inside and is sealed to the blowing shaft sleeve, a third bearing and a fourth bearing are installed at both ends of the blowing shaft sleeve, one end of the blowing shaft is fixedly connected to the blowing shaft connecting block, and the other end passes through the second bearing, the first bearing, the fourth bearing and the third bearing from right to left and extends to the outside of the blowing shaft sleeve, and a buffer spring is sleeved on the connecting end.
