Specific Embodiments

[0013] The following further describes the utility model with reference to the drawings.

[0014] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further details the utility model in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0015] Refer to Figure 1, a CNC machine tool spindle box, including a box body 1, a mounting hole 2 and a liquid outlet 3 are respectively provided on the same side of the box body 1, and both are strip-shaped holes, an oil collecting assembly 4 is provided on the mounting hole 2 and the liquid outlet 3, the oil collecting assembly 4 includes a first oil guide plate 41, a second oil guide plate 42 and an oil pipeline 43, the first oil guide plate 41 and the second guide plate 42 are fixedly connected by a connecting plate 44 to form a U-shaped structure, the first oil guide plate 42 is horizontally embedded in the box body 1 from the mounting hole 2, and the second oil guide plate 42 is horizontally embedded in the box body 1 from the liquid outlet 3, and is laid flat on the bottom of the box body, the first oil guide plate 41 is shorter than the second oil guide plate 42, and an oil drop port 45 is formed between the two, the first oil guide plate 41 is inclined toward the oil drop port 45, and the second oil guide plate 42 is inclined toward the liquid outlet 3, an oil outlet hole 46 is provided on the outer side of the second oil guide plate 42, and an oil pipeline 43 is provided at the bottom of the oil outlet hole 46. Specifically, most of the lubricating oil first falls on the first oil guide plate 42, falls along the first oil guide plate 42 from the oil drop port 45 to the second oil guide plate 42, then flows along the second oil guide plate 42 from the liquid outlet 3 to the oil outlet hole 46, and finally is discharged from the oil pipeline 43, thereby preventing the lubricating oil from accumulating at the bottom of the box; the first oil guide plate 41 and the second oil guide plate 42 provide double-layer protection for the bottom of the box; the installation method of the oil collecting assembly 4 is relatively simple, and only the first oil guide plate 41 and the second oil guide plate 42 need to be embedded into the box from the mounting socket 2 and the liquid outlet 3 respectively, and the disassembly is also relatively convenient, so it is convenient to clean the oil collecting assembly 4 after removing it.

[0016] In this embodiment, the oil delivery pipe 43 is L-shaped and extends to the other end of the box. A mounting plate 47 is hingedly mounted on its upper surface, securely connected to the side of the box via bolts 48. Because the mounting method of the oil collection assembly 4 is not stable, the mounting plate 47 is used for fixed connection; the hinged connection facilitates installation and removal of the oil collection assembly 4.

[0017] In this embodiment, a filter screen 49 is inserted into the oil delivery pipeline 43. The filter screen 49 filters impurities in the lubricating oil, thereby improving the utilization rate of the lubricating oil. At the same time, the filter screen 49 is easy to disassemble and is convenient for cleaning.

[0018] In this embodiment, the left and right side walls of the first oil guide plate 41 and the second oil guide plate 42 are both close to the inner wall of the box to try to prevent the lubricating oil from flowing out of the gap; at the same time, the left and right sides of the first oil guide plate 41 and the second oil guide plate 42 can also be provided with ribs for blocking.

[0019] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
