Abstract
Description
Technical Field
[0001] The utility model relates to the field of machine tools, in particular to a waterproof structure of a machine tool. Background Art
[0002] When a machine tool processes a workpiece, it continuously sprays cutting fluid onto the tool and the workpiece surface to lower the processing temperature and reduce the processing friction. Due to the high-speed rotation of the cutter head during processing, the cutting fluid and chips will splash everywhere. Therefore, the cutting fluid can easily flow out through the gaps in the protective cover or seep onto the ground, which can easily cause pollution to the working environment and even bring certain safety hazards.

[0023] See also Figures 1 to 2 The utility model discloses a machine tool waterproof structure comprising a main body 10 , a core shaft 20 , a sealing ring 30 , a first sealing ring 50 , a skeleton oil seal 60 , a waterproof cover 70 , a second sealing ring 80 and a third sealing ring 90 .
[0024] The core shaft 20 is mounted on the main body 10. The driving structure in the main body 10 drives the core shaft 20 to rotate, and the end of the core shaft 20 extends from the main body 10. A drainage groove 21 is provided on the core shaft 20. The drainage groove 21 is located on the outer wall of the core shaft 20 and is annular.
[0025] The sealing ring 30 is provided with a first drain port 31, a second drain port 32, and a mounting groove 33. The first drain port 31 extends from the outer diameter to the inner diameter of the sealing ring 30. The first drain port 31 is linear. The second drain port 32 and the mounting groove 33 are located on the same straight line. The mounting groove 33 is located on the inner diameter of the sealing ring 30 and is annular in shape. The second drain port 32 is connected to the mounting groove 33 and is linear. A step is formed at the location of the first drain port 31 on the sealing ring 30.
[0026] The cross section of the first sealing ring 50 is V-shaped and the two edges of the first sealing ring 50 are of different lengths. The long side of the first sealing ring 50 contacts the mounting groove 33 to achieve sealing.
[0027] The skeleton oil seal 60 is installed on the waterproof cover 70 to seal between the waterproof cover 70 and the core shaft 20 .
[0028] The sealing ring 30 is used to install the sheet metal part, which protects the entire rear end of the machine tool outside the turntable processing area.
[0029] The second sealing ring 80 is an O-shaped sealing ring. The second sealing ring 80 is installed on the sealing ring 30 and is located between the sealing ring 30 and the waterproof cover 70 to achieve sealing between the sealing ring 30 and the waterproof cover 70.
[0030] The third sealing ring 90 is an O-shaped sealing ring. The third sealing ring 90 is installed on the waterproof cover 70 and is located between the waterproof cover 70 and the main body 10 to achieve sealing between the main body 10 and the waterproof cover 70.
[0031] When assembling the machine tool's waterproof structure, the core shaft 20 is mounted on the main body 10, and the waterproof cover 70 is mounted on the core shaft 20 and located on one side of the main body 10. A skeleton oil seal 60 is mounted on the waterproof cover 70 to seal between the waterproof cover 70 and the core shaft 20. A third sealing ring 90 is mounted on the waterproof cover 70 and located between the waterproof cover 70 and the main body 10, thereby sealing the main body 10 and the waterproof cover 70. A sealing ring 30 is mounted on the core shaft 20, forming a gap 40 between the sealing ring 30 and the core shaft 20, through which cutting fluid enters the machine tool. A first sealing ring 50 is mounted in the mounting groove 33, with the opening of the first sealing ring 50 facing the second drain port 32, forming a water reservoir between the first sealing ring 50 and the second drain port 32. The water reservoir is connected to the second drain port 32 and is located on the same straight line. The two edges of the first sealing ring 50 are of different lengths, and the long side of the first sealing ring 50 contacts the mounting groove 33, achieving a seal. The first drain port 31 and the drainage groove 21 are respectively located on two sides of the gap 40 . The first drain port 31 and the drainage groove 21 correspond to each other in position and are located on the same straight line.
[0032] When the machine tool waterproof structure is in use, chip liquid enters gap 40 through the end face of sealing ring 30. Due to the presence of first sealing ring 50, chip liquid flows through drainage groove 21 into first drain port 31 for discharge. A small amount of industrial water will enter the water storage tank and be discharged through second drain port 32. When chip liquid penetrates the protective sheet metal and enters through waterproof cover 70, it will be blocked by the end face seal. After long-term use, a small amount of industrial water may pass through the end face seal and enter the water storage tank. The rear end of the water storage tank is protected by the waterproof cover mechanical maze and the skeleton oil seal 60, and will eventually be discharged through the drain port. The entire structure combines dredging and blocking, and is protected layer by layer through the mechanical structure and sealing ring structure. The structure is compact and has good protective performance.
[0033] The above embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art will be able to make various modifications and improvements without departing from the spirit of the present invention. These modifications and improvements are equivalent to those made to the above embodiments based on the essential technology of the present invention and fall within the scope of protection of the present invention.
