Description

Technical Field

[0001] The invention relates to the technical field of metal cutting machine tools, and in particular to a metal cutting machine tool for processing automobile parts. Background Art

[0002] Metal cutting machine tools are machines that use cutting, grinding or special processing methods to process various metal workpieces to obtain the required geometric shape, dimensional accuracy and surface quality. At present, a kind of shaft parts in automobile parts generally need to be placed in cutting machine tools for processing and forming, and in the metal cutting process, cutting fluid is usually sprayed for cooling. The cutting fluid can take away heat through convection and vaporization, effectively reduce the cutting temperature, reduce the thermal deformation of the tool and the workpiece, maintain the hardness of the tool and the sharpness of the cutting edge, and improve the processing accuracy and durability of the tool.

[0003] However, in the prior art, the cutting fluid spraying structure is simple, and the cutting fluid is often sprayed unevenly, resulting in poor cooling effect. In addition, the cutting fluid after spraying is mixed with metal debris, which is not easy to separate well, and thus not easy to separate, recycle and reuse, resulting in a waste of resources. Summary of the invention

The output end of the delivery pump is fixedly communicated with a delivery pipe. A slideway for slidingly connecting with the outer wall of the delivery pipe is formed at the upper part of the back surface of the machine tool main body. The rotating part of the rotating joint is hermetically and fixedly connected to the top end of the rotating pipe, and the fixed part of the rotating joint is hermetically and fixedly connected to one end of the delivery pipe.

[0012] As a preferred technical solution of the present invention, a limit slider is fixedly connected to the outer wall of the back surface of the fixed box. A transverse slide rail is fixedly connected to the inner wall of the upper part of the back surface of the machine tool main body, and the limit slider is slidably connected to the transverse slide rail.

[0013] As a preferred technical solution of the present invention, the rotary lifting clamping mechanism includes an electric push rod fixedly mounted on the inner wall of one side of the machine tool main body, a seat body fixedly connected to the telescopic end of the electric push rod, a rotating shaft rotatably mounted on the seat body, a rotary drive, and a three-jaw chuck fixedly connected to the outer wall of one end of the rotating shaft.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. When the present invention sprays cutting fluid, on the one hand, the atomizing nozzle and the coaxial fan blade rotate together. The rotating fan blade can spread the atomized cutting fluid around, increasing the coverage area of the cutting fluid, enabling the cutting fluid to more comprehensively and evenly cover the processing area, reducing heat accumulation and tool wear during cutting. On the other hand, through the effect that the shaft-type automotive parts are clamped on the rotating three-jaw chuck and rotated at high speed, and the feeding motion effect of the feeding-type cutting mechanism driving the rotating spraying cutting assembly, the uniform spraying and coverage of the cutting fluid during cutting are further improved. In this way, the problem of poor cooling effect caused by uneven spraying of traditional cutting fluid is effectively solved;

[0021] 2. When the present invention cuts, on the one hand, the rotatable three-jaw chuck facilitates clamping and rotating of shaft-type automotive parts of different specifications.

In this way, it is convenient to better adapt to the automatic cutting requirements of shaft-type automotive parts of different specifications, and the cutting efficiency and cutting quality of the cutting machine tool can be effectively improved;

[0022] 3. When dealing with cutting fluid and metal chips, on the one hand, due to the air flow effect of the high-speed rotating fan blade and the rotating throwing-off effect of the rotatable three-jaw chuck, it is difficult for the metal chips on the surface of the shaft-type automotive parts to adhere, facilitating separation and falling. On the other hand, the fallen metal chips and the sprayed cutting fluid will converge in the lower area of the machine tool main body. At this time, due to the filtering effect of the filter screen, the converged metal chips and cutting fluid are effectively separated. The separated metal chips will be swept out by the cleaning assembly for recycling, and the separated cutting fluid will be discharged through the drain pipe on one side of the waste liquid collection pool for recycling, thus reducing the situation of resource waste.
