The trimming part includes a translation part 20, a lifting part 30 and a trimming part 40. The translation part 20 includes a first motor 21, a first support platform 22, a first lead screw 23 and a first slider 24. The first support platform 22 is arranged on the top of the base 10, and a first chute 25 is opened on the top. One end of the first motor 21 is arranged in the first chute 25. One end of the first lead screw 23 is connected to the first motor 21, and the other end is rotatably connected to the inner wall of the first chute 25. The first slider 24 is slidably arranged in the first chute 25, and a ball nut matching the first lead screw 23 is arranged in the middle. The lifting part 30 is arranged on the translation part 20. The translation part 20 includes a second motor 31, a second support platform 32, a second lead screw 33 and a second slider 34. The second support platform 32 is arranged on the top of the first slider 24. A second chute 35 is arranged on one side of the second support platform 32 close to the fixing part. One end of the second motor 31 is arranged at the top end in the second chute 35. One end of the second lead screw 33 is connected to the second motor 31, and the other end is rotatably connected to the inner wall of the bottom end of the second chute 35. The second slider 34 is slidably arranged in the second chute 35, and a ball nut matching the second lead screw 33 is arranged in the middle. The first motor 21 and the second motor 31 are both servo motors. The trimming part 40 is arranged on the second slider 34 and is used for trimming the step drill 90. The fixing part includes a fixing frame 51 and a fixing claw 52 arranged on one side of the top of the fixing frame 51 close to the trimming part. The fixing frame 51 is arranged on the top of the base 10, and a rotating motor 53 connecting the fixing claw 52 is arranged on the top of the fixing frame 51. The cleaning part is arranged on the base 10 and includes a collection tank 60, a liquid tank 70 and a water pump 80. The collection tank 60 is arranged at the bottom of the fixing claw 52. A liquid discharge port 61 with a valve is arranged at the bottom of the collection tank 60. A delivery pipe 81 is arranged between the input end of the water pump 80 and the liquid tank 70. A flushing pipe 82 is arranged at the output end of the water pump 80. A liquid injection port 71 is arranged at the top of the liquid tank 70, and the coolant can be injected from the liquid injection port 71 of the liquid tank 70.
[0030] The working principle of the above technical solution is as follows:
[0031] The fixing claw 52 of the fixing part can fix the tail end of the step drill 90. When adjusting the position of the trimming part 40, start the first motor 21 to rotate the first lead screw 23, translate the first slider 24, move the lifting part 30 and the horizontal position of the trimming part 40. Start the second motor 31 to rotate the second lead screw 33, lift the second slider 34, and lift the height of the trimming part 40 until the trimming part 40 approaches the step drill 90. During this process, the rotating motor 53 rotates the fixing claw 52 to realize the rotation of the step drill 90, and the trimming part 40 can trim the chamfer of the step drill 90. The metal chips generated during the trimming process can fall into the collection tank 60. Before and after trimming, the water pump 80 can be started to extract the coolant in the liquid tank 70 through the delivery pipe 81 and conduct flushing through the flushing pipe 82, which has the effects of cooling and cleaning at the same time, facilitating the metal chips to fall into the collection tank 60. For subsequent treatment, the drain port 61 can be opened to drain to the designated position.
[0032] In another embodiment, as Figure 2 shown, a funnel opening 62 is provided at the top of the collection tank 60. The funnel opening 62 provided at the top of the collection tank 60 facilitates the entry of metal chips and coolant into the collection tank 60, preventing them from splashing onto the base 10.
[0033] In another embodiment, as Figure 2 shown, a detachable filter screen 63 is provided between the collection tank 60 and the funnel opening 62. The filter screen 63 can separate the metal chips from the coolant. The separated metal chips remain on the filter screen 63, facilitating separate recycling.
[0034] In another embodiment, the flushing pipe 82 is selected as a gooseneck pipe. The gooseneck pipe facilitates the adjustment of the flushing angle and position.
[0035] In another embodiment, as Figure 4 shown, the trimming part 40 includes a connecting seat 41 connecting the second slider 34, a fastening member, and a trimming tool 42. A first connecting hole is provided on the top side of the connecting seat 41, and a second connecting hole is provided at the bottom of the trimming tool 42. The fastening member includes a bolt 43 and a wing nut 44. The bolt 43 passes through the first connecting hole and the second connecting hole to connect the wing nut 44. The wing nut 44 is convenient to loosen. After rotating the angle of the trimming tool 42, it can be tightened again to fix the trimming tool 42, facilitating the adjustment of the trimming angle of the trimming tool 42.
