[0041] Embodiment 3

[0042] Refer to Figure 2 and Figure 5 This embodiment is different from the above embodiments in that: a lubrication assembly 300 that can automatically supply lubricating oil is provided. The lubrication assembly 300 realizes or cancels the lubrication effect between various components inside the machine tool body 1 under the action of an oil pump 302, pipe joints, pipelines, and nozzles 303, increasing the service life and transmission efficiency.

[0043] Specifically, the oil outlet pipe 301a at the bottom of the rear end face of the fuel tank 301, the other end of the oil outlet pipe 301a is connected to the oil inlet end of the oil pump 302 through a pipe joint. The oil outlet end of the oil pump 302 is respectively connected to the middle oil delivery pipe 302a and the outer oil delivery pipes 302b on both sides through a four-way joint. The other ends of the middle oil delivery pipe 302a and the outer oil delivery pipes 302b are both connected to the nozzle 303 through pipe joints. The nozzle 303 is located inside the machine tool body 1. An oil inlet pipe 301b is provided at the center position of the top of the fuel tank 301. The other end of the oil inlet pipe 301b is respectively connected to the middle oil return pipe 304 and the circulation pipes 305 on both sides through a four-way joint. The other end of the circulation pipe 305 is connected to the outer oil return pipe 306 through a pipe joint. The other ends of the middle oil return pipe 304 and the outer oil return pipe 306 are both arranged at the bottom of the machine tool body 1.

[0044] Furthermore, the pipe joints and the four-way joints both play a role in connecting pipelines. When the oil pump 302 operates, the lubricating oil in the fuel tank 301 can be pumped out through the oil outlet pipe 301a, and then transported through multiple oil delivery pipes, and finally sprayed out from the nozzle 303 onto the transmission mechanism to lubricate it. The excess dripping lubricating oil can return to the fuel tank 301 through multiple oil return pipes, playing a role in recycling.

[0045] Operation process: When the transmission components inside the machine tool body 1 are running, start the oil pump 302. The oil pump 302 operates to draw out the lubricating oil inside the oil tank 301 through the outlet oil pipe 301a, and then transports the lubricating oil through the middle oil pipe 302a and the outer oil pipes 302b on both sides. Then, the lubricating oil can be sprayed out through the corresponding nozzles 303 to the tooth disc meshing part, thereby playing a lubricating role in the tooth disc meshing part, increasing the service life of the transmission components, reducing wear. The lubricating oil dripping from the transmission components will be recovered through the middle return oil pipe 304 and the outer return oil pipes 306 on both sides, and then under the action of the circulation pipe 305, it will return to the inside of the oil tank 301 again from the inlet oil pipe 301b, achieving the effect of recycling the lubricating oil, reducing the waste of lubricating oil, and improving the resource utilization efficiency.
