During use, the supply pipe joint 2 is connected to an external liquid supply pipeline, and the coolant or fluid enters the rotary head body 1 through the supply pipe joint 2, and the rotor joint 3 is connected to the rotating shaft of the external driving source. The coolant or fluid is transported from the rotary head body 1 to the rotor joint 3, and then enters the spindle of the external processing equipment and its cutting tool. This is the prior art of the existing rotary head body 1, and it will not be repeated here. By setting the filter assembly 4, the filter assembly 4 can filter the incoming fluid to prevent impurities from entering the rotary head body 1 and affecting the service life of the rotary head body 1. By setting the disassembly assembly 5, the disassembly assembly 5 can facilitate the operator to disassemble the cover plate 43 and the filter disc 48, thereby facilitating the cleaning of impurities or the replacement of the filter disc 48.

[0025] The filter assembly 4 includes a sleeve 41, one end of which is fixedly connected to a tapered channel tube 42, one end of which is fixedly connected to an end of the supply pipe joint 2 away from the rotating head body 1, and a cover plate 43 is detachably installed on the end of the sleeve 41 away from the tapered channel tube 42, a joint pipe 44 is fixedly connected at the center position of the cover plate 43, an outer wall of the joint pipe 44 is provided with an external thread groove 45, and a filter disc 48 is detachably installed on the inner wall of the sleeve 41. By arranging the sleeve 41, the tapered channel tube 42, the cover plate 43, the joint pipe 44, the external thread groove 45 and the filter disc 48, the external thread groove 45 can facilitate the operation to make the joint pipe 44 threadedly connected to the interface of the external liquid supply pipeline, and the coolant or medium enters the sleeve 41 through the joint pipe 44, and the filter disc 48 in the sleeve 41 can filter the entering coolant or medium to prevent impurities from entering the rotating head body 1.

[0026] A limiting disk 46 is fixedly installed at one end of the joint pipe 44 close to the cover plate 43, and a first sealing ring 47 is fixedly installed on the upper surface of the limiting disk 46. By setting the limiting disk 46 and the first sealing ring 47, the sealing between the joint pipe 44 and the interface of the external liquid supply pipeline can be improved when connected to the interface of the external liquid supply pipeline.

[0027] A support ring 49 is fixedly installed on the inner wall of the sleeve 41, and a second sealing ring 491 is fixedly installed on one side of the support ring 49.

By arranging the support ring 49 and the second sealing ring 491, the support ring 49 can support the filter disc 48 through the second sealing ring 491, and at the same time, the second sealing ring 491 can improve the sealing between the filter disc 48 and the support ring 49 to prevent unfiltered coolant or medium from penetrating downward.

[0028] The disassembly assembly 5 includes two L-shaped limiting rods 51 and two Z-shaped elastic members 58. The two L-shaped limiting rods 51 are arranged on the lower surface of the cover plate 43. The inner wall of the sleeve 41 is provided with two limiting holes 52. One end of one of the L-shaped limiting rods 51 is movably plugged into the inner wall of the limiting hole 52. The inner wall of the sleeve 41 is provided with two grooves 57. One end of one of the Z-shaped elastic members 58 is fixedly installed on the side wall of one of the grooves 57. The other ends of the two Z-shaped elastic members 58 are movably connected to the upper surface of the filter plate 48. By setting an L-shaped limit rod 51 and a limit hole 52, when the L-shaped limit rod 51 moves horizontally to the inside of the limit hole 52, the L-shaped limit rod 51 can limit and fix the cover plate 43 through the limit hole 52, so that the cover plate 43 is fixed to the upper end surface of the sleeve 41, and by setting a Z-shaped elastic member 58, the extended state of the two Z-shaped elastic members 58 can limit the filter plate 48 above the support ring 49, and when the two Z-shaped elastic members 58 are in the contracted state, the filter plate 48 can be taken out from above the support ring 49.

[0029] Two slide grooves 53 are provided on the lower surface of the cover plate 43, and a slider 54 is slidably installed at one end of the two slide grooves 53. One end of an L-shaped limit rod 51 away from the limit hole 52 is fixedly connected to the lower surface of a slider 54. By setting the slide groove 53 and the slider 54, when the slider 54 slides horizontally along the inner wall of the slide groove 53, the slider 54 can move the L-shaped limit rod 51 in the horizontal direction.

[0030] Threaded rods 55 are rotatably mounted on both sides of the cover plate 43 , wherein one of the threaded rods 55 passes through a slide groove 53 and is threadably connected to a slider 54 . By rotating the threaded rod 55 , the threaded rod 55 can drive the slider 54 to slide horizontally along the inner wall of the slide groove 53 .

[0031] A rotating disk 56 is fixedly mounted on one end of the two threaded rods 55 . The rotating disk 56 is provided to facilitate operators to rotate the threaded rods 55 .

[0032] A circular sealing gasket 59 is fixedly installed on the lower surface of the cover plate 43, and a connecting groove 6 is opened at one end of the sleeve 41 away from the conical channel tube 42. The circular sealing gasket 59 and the inner wall of the connecting groove 6 are interference fit. By arranging the circular sealing gasket 59 and the connecting groove 6, when the cover plate 43 is placed on the upper end surface of the sleeve 41, the cover plate 43 is pressed downward, and the downward pressure squeezes the circular sealing gasket 59 into the connecting groove 6, thereby improving the sealing between the cover plate 43 and the sleeve 41.

[0033] Working principle: by arranging a sleeve 41, a tapered channel tube 42, a cover plate 43, a joint tube 44, an external thread groove 45 and a filter disc 48 at the end of the supply pipe joint 2, when the interface of the external liquid supply pipeline is threadedly connected with the external thread groove 45, the interface of the external liquid supply pipeline is connected with the joint tube 44, and the coolant or medium in the external liquid supply pipeline enters the sleeve 41 through the joint tube 44. At this time, the filter disc 48 filters the coolant or medium to prevent impurities in the coolant or medium from flowing into the interior of the rotating head body 1, thereby conveniently realizing the filtering of the coolant or medium, thereby preventing the rotating head body 1 from being damaged due to excessive impurities entering, and at the same time improving the service life of the rotating head body 1;

[0034] When it is necessary to clean the impurities on the filter disc 48, the operator first rotates the two rotating discs 56 respectively, the two rotating discs 56 rotate the two threaded rods 55, the two threaded rods 55 drive the two sliders 54 to slide towards each other, the two sliders 54 make the two L-shaped limit rods 51 approach each other, so that the two L-shaped limit rods 51 are separated from the inner walls of the two limit holes 52, and then remove the cover plate 43 from the upper end of the sleeve 41. At this time, the sleeve 41 is in an open state;

[0035] Subsequently, the operator presses the two Z-shaped elastic parts 58 with their backs to each other at the same time, causing the two Z-shaped elastic parts 58 to shrink into the two grooves 57, thereby releasing the limit of the filter disc 48 and taking out the filter disc 48 from the sleeve 41, thereby facilitating the disassembly of the filter disc 48 and effectively improving the convenience of cleaning or replacing the filter disc 48.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
