[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The present application embodiment discloses a cutting fluid reflux structure for a machining center. Figure 1-2 A cutting fluid reflux structure for a machining center includes a shell 1, a motor 2 is installed on the left outer wall of the shell 1, a recovery chamber 3 is arranged in the shell 1, a reciprocating screw 6 is rotatably connected between the left and right inner walls of the recovery chamber 3, a slider 14 is threadedly connected to the reciprocating screw 6, a guide rod 15 is fixedly connected between the left and right inner walls of the recovery chamber 3, the guide rod 15 passes through the slider 14 and is slidably connected to the slider 14, a brush layer 16 is fixedly connected to the lower end of the slider 14, and a reflux mechanism for the cutting fluid of the machining center is arranged in the shell 1.
[0020] Reference Figure 1-3 The reflux mechanism includes a first filter screen 10 fixedly connected between the front and rear inner walls of the recovery chamber 3, and a collecting box 11 is arranged on both sides of the first filter screen 10. A second filter screen 9 is slidably connected between the left and right inner walls of the recovery chamber 3, and a rotating rod 4 is rotatably connected between the left and right inner walls of the recovery chamber 3. The output shaft end of the motor 2 extends into the recovery chamber 3 and is fixedly connected to one end of the rotating rod 4. Two cams 5 are fixedly connected to the rotating rod 4, and one end of the two cams 5 is always against the lower end of the second filter screen 9. Fixed blocks 12 are fixedly connected to the left and right inner walls of the recovery chamber 3, and the lower ends of the two fixed blocks 12 are elastically connected to the upper end of the second filter screen 9 through connecting springs 13. One end of the rotating rod 4 and the reciprocating screw rod 6 extend to the right side of the shell 1 and are fixedly connected with a synchronous transmission wheel 7. The two synchronous transmission wheels 7 are connected through a synchronous transmission belt 8. The density of the second filter screen 9 is less than that of the first filter screen 10.
[0021] After the motor 2 is started, it will drive the rotating rod 4 to rotate. When the rotating rod 4 rotates, the reciprocating screw 6 will rotate through the transmission of the synchronous transmission belt 8, and then the slider 14 threadedly connected to it will drive the brush layer 16 to reciprocate left and right, and then the chips on the upper end of the first filter 10 will be scraped into the two collecting boxes 11 through the brush layer 16, effectively separating the chips from the cutting fluid. At the same time, when the rotating rod 4 rotates, it will drive the two cams 5 to rotate, and cooperate with the two connecting springs 13 to make the second filter 9 vibrate to avoid clogging of the second filter 9.

[0023] The implementation principle of the cutting fluid reflux structure of a machining center in the embodiment of the present application is as follows: the used cutting fluid will fall to the inner bottom of the housing 1 through the first filter screen 10 and the second filter screen 9, and the chips and the cutting fluid will be separated by the first filter screen 10 and the second filter screen 9 to ensure the cleanliness and reusability of the cutting fluid;
[0024] In the above process, the motor 2 is started, and the motor 2 drives the rotating rod 4 to rotate. When the rotating rod 4 rotates, the reciprocating screw rod 6 is driven by the synchronous transmission belt 8, and then the slider 14 threadedly connected thereto drives the brush layer 16 to reciprocate left and right, and then the chips on the upper end of the first filter screen 10 are scraped into the two collecting boxes 11 through the brush layer 16, so that the chips and the cutting fluid are effectively separated. At the same time, when the rotating rod 4 rotates, the two cams 5 are driven to rotate, and the two connecting springs 13 are cooperated to make the second filter screen 9 vibrate to avoid the second filter screen 9 from being blocked.
[0025] Subsequent staff can open the sliding door on the front side of the housing 1 and collect and clean the chips on the two collection boxes 11 and the second filter screen 9 .
