[0002] Inclined CNC machine tools are a type of CNC machine tools. Its characteristic is that the machine tool structure design adopts an inclined method. Usually, the worktable is inclined in the horizontal direction. This design prolongs the tool life and can provide better cutting stability and higher processing accuracy. In order to further reduce thermal deformation and tool wear, it is necessary to use a tool lubrication structure with cutting fluid to lubricate the tool to improve processing quality and tool life.

[0003] Vientiane bamboo tube is often used as a tool lubrication structure on inclined CNC machine tools to transport cutting fluid.

In addition, the Wanxiang bamboo tube will be damaged on the surface of the pipe after long-term use, wear and aging, making the Wanxiang bamboo tube loose and unable to be adjusted accordingly according to the length of the workpiece. For this reason, we provide a tool lubrication structure for inclined CNC machine tools. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Example 1

[0035] like Figure 1~Figure 5 As shown, this embodiment proposes a tool lubrication structure for an inclined CNC machine tool, including a mounting shell 1 , wherein the mounting shell 1 includes a housing 101 , and a slide groove 102 is provided on the bottom surface of the housing 101 .

[0036] Please refer to Figure 3 and Figure 4 A moving mechanism 2 for lateral adjustment of the liquid spraying assembly 3 is arranged inside the mounting shell 1. The moving mechanism 2 includes a screw rod 201 rotatably connected to the inner wall of the shell 101 through a bearing. A slider 202 whose top surface is in sliding contact with the inner top wall of the shell 101 is threadedly connected to the surface of the screw rod 201. A connecting plate 203 is fixed to the bottom surface of the slider 202. A knob 204 is fixed to the right end of the screw rod 201. The outer contour of the knob 204 is cylindrical.

[0037] The knob 204 provides a reasonable force point for rotating the screw rod 201, which is convenient to use. The rotation of the screw rod 201 will drive the slider 202 limited by the guide rod 501 and the linear bearing 502 to move horizontally, and the movement of the slider 202 will drive the connecting plate 203 to move.

[0038] Please refer to Figure 3 and Figure 5 A liquid spraying assembly 3 for spraying cutting fluid is arranged inside the shell 101. The liquid spraying assembly 3 includes a bellows 301 connected to the cutting fluid supply system of the CNC machine tool. A fixing ring 302 is fixed to the other end of the bellows 301. A connecting seat 303 hinged to the connecting plate 203 is fixed to the top surface of the fixing ring 302. The output end of the bellows 301 is connected to a nozzle 304.

[0039] The input end of the bellows 301 is connected to the cutting fluid supply system of the CNC machine tool. Through the cooperation of the bellows 301 and the nozzle 304, the cutting fluid can be sprayed on the tool to achieve cooling and lubrication of the tool and increase the service life of the tool. The connecting seat 303 and the connecting plate 203 are hinged, and the connecting plate 203 cannot rotate on the connecting seat 303 along the axial direction of the screw rod 201 to ensure that the connecting plate 203 can drive the connecting seat 303 and the fixing ring 302 fixed on the bottom surface of the connecting seat 303 to move along the axial direction of the screw rod 201.

[0040] Please refer to Figure 3 and Figure 4 A rotating mechanism 4 for adjusting the angle of the spray assembly 3 is arranged inside the mounting shell 1, and the rotating mechanism 4 includes a square telescopic tube 401 fixed to one side of the connecting seat 303, and a rotating shaft 402 is fixed at one end of the square telescopic tube 401 away from the connecting seat 303, which is rotatably connected to the right side wall of the shell 101 through a bearing, and the rotating shaft 402 extends to one end of the right side of the shell 101 and is slidably sleeved with a limit plate 403 fixed to the right side surface of the shell 101, and a plurality of evenly distributed limit holes 404 are opened on the right side surface of the limit plate 403, and a rotating plate 405 is fixed to the right end of the rotating shaft 402, and limit rods 406 extending to the inside of the limit holes 404 are slidably connected at both ends of the rotating plate 405.

[0041] By inserting the limiting rod 406 into the limiting hole 404, the rotating shaft 402 can be limited in cooperation with the rotating plate 405, and then the square telescopic tube 401, the connecting seat 303, the fixing ring 302, the bellows 301 and the nozzle 304 are limited to prevent the spraying direction of the nozzle 304 from shaking. The limiting rod 406 is pulled out of the limiting hole 404, and the rotating shaft 402 is rotated to adjust the spraying direction of the nozzle 304.

[0042] A fixing plate 408 is fixed to the right ends of the two limiting rods 406 , and a grip groove 409 is provided on the fixing plate 408 . Two tension springs 407 , which are respectively sleeved on the sides of the limiting rods 406 , are fixed between the fixing plate 408 and the rotating plate 405 . The diameter of the limiting hole 404 is greater than the diameter of the limiting rod 406 .

[0043] The square telescopic tube 401 is preferably square and is composed of a plurality of square rods. The plurality of square rods can be telescoped but cannot be rotated. The limit rod 406 and the fixed plate 408 can be positioned by the tension spring 407 so that the limit rod 406 is inserted into the limit hole 404 to limit the rotating plate 405. When the fixed plate 408 is pulled, the tension spring 407 and the limit rod 406 will also be pulled. When the left end of the limit rod 406 moves into the rotating plate 405, the fixed plate 408 is rotated, and the rotating plate 405 is rotated in cooperation with the fixed plate 408 and the limit rod 406, thereby causing the rotating shaft 402 and the square telescopic tube 401 to rotate.

[0044] In this embodiment, the cutting fluid can be sprayed on the tool by the bellows 301 connected to the cutting fluid supply system of the CNC machine tool in cooperation with the nozzle 304 to achieve cooling and lubrication of the tool. Then, the screw rod 201 is rotated by the knob 204. The rotation of the screw rod 201 can drive the slider 202, the connecting plate 203, the connecting seat 303, the fixing ring 302, the bellows 301 and the nozzle 304 to move, and then the corresponding adjustment is made according to the length of the workpiece to be processed, and the limit rod 406 is pulled to the rotating plate 4 05, rotate the fixed plate 408, and the fixed plate 408 and the limit rod 406 cooperate to rotate the rotating plate 405, so that the rotating shaft 402 and the square telescopic tube 401 are rotated, and the square telescopic tube 401 will drive the connecting seat 303, the fixed ring 302, the bellows 301 and the nozzle 304 to rotate, so as to adjust the angle of the nozzle 304 spraying the cutting fluid. The device has high structural strength and strong stability, and can stably make corresponding adjustments according to the length of the workpiece to be processed.

When the slider 202 moves, it will also drive the linear bearing 502 to slide on the guide rod 501. Through the coordinated setting of the guide rod 501 and the linear bearing 502, the movement of the slider 202 can be made more stable.

[0047] Please refer to Figure 2 and Figure 3A plurality of mounting plates 103 are fixed to the left side of the shell 101, and circular holes are opened on the plurality of mounting plates 103. The width of the slide groove 102 is greater than the diameter of the outer contour of the nozzle 304. The output end of the nozzle 304 is downward.
