[0028] like Figure 1-Figure 5As shown, a cutting fluid injection device for mechanical processing and manufacturing includes a box body 1, the four corners of the bottom of the box body 1 are fixedly connected to support legs 11, the front of the box body 1 is rotatably connected to a box door 12, the bottom of the inner cavity of the box body 1 is overlapped with a cutting fluid box 13, the left side of the cutting fluid box 13 is fixedly connected to a liquid inlet pipe 14, the outer wall of the liquid inlet pipe 14 is fixedly connected to the inner wall of the left side of the box body 1, the upper and lower sides of the right end of the box body 1 are fixedly connected to a connecting block 15, the top of the box body 1 is fixedly connected to a shell 17, the bottom of the inner cavity of the shell 17 is fixedly connected to a processing plate 18, the left and right sides of the inner wall of the top of the box body 1 are fixedly connected to a reflux port 16, and the outer walls of the two reflux ports 16 are respectively connected to the shell 17 The inner walls on the left and right sides of the bottom are fixedly connected, the outer walls on the left and right sides of the cutting fluid box 13 are fixedly connected with a vibration mechanism 3, the top of the inner cavity of the shell 17 is fixedly connected with a left and right moving mechanism 5, and the outer wall of the left and right moving mechanism 5 is rotatably connected with an adjustment mechanism 4; the vibration mechanism 3 includes two motors 31, the bottoms of the two motors 31 are respectively fixedly connected to the left and right sides of the cutting fluid box 13, the left and right moving mechanism 5 includes a fixed box 51 and a fixed column 57, the top of the fixed box 51 is fixedly connected to the top of the inner cavity of the shell 17, the adjustment mechanism 4 includes a fixed block 41, the inner wall of the fixed block 41 is rotatably connected to the outer wall of the fixed column 57, and the bottom of the fixed block 41 is fixedly connected with a nozzle 44.

[0029] The nozzle 44 is driven to move by the left-right moving mechanism 5. When the position is suitable, the left-right moving mechanism 5 is closed, and then the angle of the nozzle 44 is changed by the adjusting mechanism 4 so that the direction of the nozzle 44 is more convenient for spraying cutting fluid on the cutting tool. Then the sprayed cutting fluid flows into the cutting fluid tank 13 again through the reflux port 16, and the screen 36 is vibrated by the vibration mechanism 3 to prevent the screen 36 from being blocked.

[0030] like Figure 2 As shown, a water pump 2 is fixedly connected to the right side of the bottom of the inner cavity of the box body 1, and the output end and input end of the water pump 2 are fixedly connected to the pipe 21, the outer wall of the left pipe 21 passes through the outer wall on the right side of the cutting fluid box 13 and extends to the inner cavity of the cutting fluid box 13, the outer wall of the right pipe 21 is fixedly connected to the inner walls of the two connecting blocks 15, the outer wall at the top of the right pipe 21 is fixedly connected to the inner wall on the right side of the outer shell 17 near the upper end, the left side of the right pipe 21 is fixedly connected with a hose 22, the left side of the hose 22 is fixedly connected to the right side of the fixed block 41, and the hose 22, the fixed block 41 and the nozzle 44 are connected to each other.

[0031] The water pump 2 is started to draw the cutting fluid in the cutting fluid box 13 through the pipeline 21 and transport it to the hose 22 . The hose 22 then transports the cutting fluid to the nozzle 44 at the bottom of the fixed block 41 and the cutting fluid is sprayed out by the nozzle 44 .

[0032] like Figure 2-Figure 4As shown, the output ends of the two motors 31 are fixedly connected with incomplete gears 32, the outer walls of the opposite surfaces of the two incomplete gears 32 are meshed with toothed plates 33, the outer walls of the opposite surfaces of the two toothed plates 33 are slidably connected to the outer walls on the left and right sides of the cutting fluid box 13, and the inner walls on the front and rear sides of the two toothed plates 33 are slidably connected with guide blocks 34, and the opposite surfaces of the four guide blocks 34 are fixedly connected to the outer walls on the left and right sides of the cutting fluid box 13.

[0033] By starting the motor 1 31, the incomplete gear 32 is driven to rotate, so that the incomplete gear 32 is engaged with the tooth plate 33, and the tooth plate 33 is driven to move downward, so that the tooth plate 33 slides on the inner wall of the cutting fluid box 13, and at the same time, the guide block 34 slides on the inner wall of the tooth plate 33 to guide the tooth plate 33.

[0034] like Figure 3 , Figure 4 As shown, the tops of the two tooth plates 33 are fixedly connected with connecting blocks 2 35, the outer walls of the two connecting blocks 2 35 are respectively slidably connected to the inner walls of the left and right sides of the cutting fluid box 13 near the upper end, the tops of the two connecting blocks 2 35 near the opposite surfaces are fixedly connected with screens 36, the outer walls of the screens 36 are slidably connected to the inner cavity of the cutting fluid box 13, the front and rear sides of the two connecting blocks 2 35 are fixedly connected with sliders 1 351, the outer walls of four sliders 1 351 are respectively slidably connected to the middle of the left and right sides of the cutting fluid box 13 near the upper end, the inner walls of the front and rear sides of the left and right ends of the screen 36 are slidably connected with sliding rods 37, the upper and lower ends of the four sliding rods 37 are respectively fixedly connected to the inner wall of the cutting fluid box 13, and the outer walls of the four sliding rods 37 are slidably connected with sliders 2 38.

[0035] When the tooth plate 33 slides, it also drives the connecting block 2 35 to move downward, and the connecting block 2 35 drives the screen 36 to move downward synchronously. When the connecting block 2 35 slides, it drives the slider 1 351 to slide on the inner wall of the cutting fluid box 13, thereby guiding the slider 1 351, so that the slider 1 351 slides more smoothly, thereby making the screen 36 slide downward on the outer wall of the slide rod 37, and making the slider 2 38 shrink. When the incomplete gear 32 rotates to a toothless place, the incomplete gear 32 no longer meshes with the tooth plate 33. At this time, under the action of the elastic force of the slide rod 37, the screen 36 moves upward, thereby making the screen 36 vibrate up and down, avoiding the blockage of the screen 36, thereby preventing the blockage.

[0036] like Figure 5 , Figure 6 As shown, the inner wall of the fixed block 41 is fixedly connected with springs 42 in a circular array, the bottom ends of the springs 42 are fixedly connected with limit blocks 43, the outer wall of the limit blocks 43 is slidably connected to the inner wall of the fixed block 41, and the outer wall of the limit blocks 43 is clamped with the inner wall of the fixed column 57.

[0037] By adjusting the nozzle 44 according to the required angle and rotating the fixed block 41, the nozzle 44 is driven to rotate synchronously. During rotation, the outer wall of the limit block 43 rubs against the inner wall of the fixed column 57, so that the limit block 43 slides toward the inner wall of the fixed block 41, driving the spring 42 to contract. When it is turned to a suitable position, the fixed block 41 stops rotating. At this time, under the action of the elastic force of the spring 42, the outer wall of the limit block 43 is again engaged with the outer wall of the fixed column 57, thereby positioning the fixed block 41 so that the fixed block 41 cannot continue to rotate without external force, thereby achieving the effect of adjusting the angle.

[0038] like Figure 2 As shown, the left side of the fixed box 51 is fixedly connected with a motor 2 52, the output of the motor 2 52 passes through the outer wall of the left side of the fixed box 51 and is fixedly connected with a threaded rod 53, the right side of the threaded rod 53 is rotatably connected to the right side of the inner cavity of the fixed box 51, the outer wall of the threaded rod 53 is threadedly connected with a slider 3 54, the bottom of the slider 3 54 is fixedly connected with a telescopic cylinder 55, the bottom of the telescopic cylinder 55 is fixedly connected with a cutting knife, the right side of the telescopic cylinder 55 is fixedly connected with a support plate 56, and the front of the support plate 56 is fixedly connected with a fixed column 57.

[0039] By starting the second motor 52, the threaded rod 53 is driven to rotate, so that the slider three 54 slides on the outer wall of the threaded rod 53, driving the support plate 56 at the bottom of the telescopic cylinder 55 to move synchronously, the support plate 56 drives the fixed block 41 to move synchronously, and the fixed block 41 drives the nozzle 44 to move synchronously. When the movement drives the appropriate position, the second motor 52 is turned off, which has the effect of adjusting the left and right position of the nozzle 44.

[0040] The working principle of the utility model is as follows: when in use, the second motor 52 is started to drive the threaded rod 53 to rotate, so that the slider 3 54 slides on the outer wall of the threaded rod 53, and drives the support plate 56 at the bottom of the telescopic cylinder 55 to move synchronously. When the movement drives the appropriate position, the second motor 52 is turned off, and then the cutting work can be started. At the same time, the nozzle 44 is adjusted according to the required angle, and the fixed block 41 is rotated to drive the nozzle 44 to rotate synchronously. When rotating, the outer wall of the limit block 43 rubs against the inner wall of the fixed column 57, so that the limit block 43 moves toward the fixed block 41. The inner wall of the fixing block 41 slides, driving the spring 42 to contract. When it turns to a suitable position, the fixing block 41 stops rotating. At this time, under the action of the elastic force of the spring 42, the outer wall of the limit block 43 is again engaged with the outer wall of the fixing column 57, thereby positioning the fixing block 41 so that the fixing block 41 cannot continue to rotate without external force, thereby achieving the effect of adjusting the angle. Subsequently, the water pump 2 can be started, and the cutting fluid in the cutting fluid box 13 is extracted by the pipeline 21 and transported to the hose 22, and then transported to the nozzle 44 at the bottom of the fixing block 41 by the hose 22. , sprayed by the nozzle 44, the sprayed liquid falls into the inner cavity of the shell 17, enters the cutting fluid box 13 again through the reflux port 16, and falls on the screen 36. The cutting fluid is filtered by the screen 36, and the iron filings in the cutting fluid are filtered out, which has a filtering effect. At the same time, the motor 31 is started to drive the incomplete gear 32 to rotate, so that the incomplete gear 32 is meshed with the tooth plate 33, and the tooth plate 33 is driven to move downward, so that the tooth plate 33 slides on the inner wall of the cutting fluid box 13, and the guide block 34 slides on the inner wall of the tooth plate 33, 33 is used for guiding, and the tooth plate 33 simultaneously drives the connecting block 2 35 to move downward, and the connecting block 2 35 drives the screen 36 to move downward synchronously, so that the screen 36 slides downward on the outer wall of the slide bar 37, and the slide block 2 38 shrinks. When the incomplete gear 32 rotates to a toothless place, the incomplete gear 32 no longer meshes with the tooth plate 33. At this time, under the action of the elastic force of the slide bar 37, the screen 36 moves upward, thereby making the screen 36 in a state of up and down vibration, avoiding the screen 36 from being blocked, and having the effect of preventing blockage, thereby greatly improving the user experience.
