[0017] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] refer to Figures 1 to 12 The milling equipment for processing the end cover of the power distribution cabinet shown in the figure includes a milling tool, which is composed of a tool handle 1 and a threaded tool head 2 (such as Figure 3 As shown in the figure, the tool handle 1 is columnar and vertically arranged, the threaded cutter head 2 rotates at the lower end of the tool handle 1, and also includes a flaring and chip suction mechanism, a chip storage mechanism, a vent valve and a sealing valve. The flaring and chip suction mechanism includes a fixed seat 3, a lifting pipe 4, a No. 1 spring 5 and a flaring cover 6. The fixed seat 3 is connected to the lower end of the tool handle 1, and the lifting pipe 4 (as shown in the figure) is connected to the lower end of the tool handle 1. Figure 6 As shown in the figure, the expansion housing 6 is vertically connected to the fixed seat 3 for sliding, the expansion housing 6 is sleeved on the outside of the threaded cutter head 2, the first spring 5 is vertically arranged between the expansion housing 6 and the fixed seat 3, the chip storage mechanism includes a T-shaped tube 7 and a storage tank 8, the T-shaped tube 7 is fixedly connected to the tool handle 1, and the T-shaped tube 7 is provided with a discharge port 9, a first port 10 and a second port 11, the discharge port 9 (as shown in the figure) is vertically connected to the fixed seat 3 for sliding, the expansion housing 6 is sleeved on the outside of the threaded cutter head 2, the first spring 5 is vertically arranged between the expansion housing 6 and the fixed seat 3, the chip storage mechanism includes a T-shaped tube 7 and a storage tank 8, the T-shaped tube 7 is fixedly connected to the tool handle 1, and the T-shaped tube 7 is provided with a discharge port 9, a first port 10 and a second port 11. Figure 8 As shown) is arranged at the lower end of the T-shaped tube 7, the first port 10 and the second port 11 are arranged opposite to each other (combined with Figure 7 and Fig. 9 ), a material separation mesh plate 12 is provided in the No. 2 port 11, the storage tank 8 is connected to the discharge port 9, a vent valve is provided on the No. 1 port 10, the vent valve comprises a valve pipe 13, a valve pin 14 and a slide pipe 15, the valve pipe 13 is vertically connected to the No. 1 port 10, the upper end of the slide pipe 15 is upwardly inserted into the valve pipe 13, and a vent notch 16 is provided on the top of the slide pipe 15 (such as Fig.11 As shown in FIG. 1 ), the valve pin 14 slides in the upper end of the slide tube 15, and a connecting elbow 17 (as shown in FIG. 1 ) is provided between the lower end of the slide tube 15 and the expansion housing 6. Figure 5As shown in the figure, the sealing valve is arranged in the storage tank 8, and the sealing valve includes a sliding rod 18 and a plug 19. The sliding rod 18 slides in the storage tank 8 along the vertical direction, the plug 19 is arranged at the upper end of the sliding rod 18, and the sliding rod 18 is connected to the sliding tube 15.

[0019] In actual use, the tool handle 1 of the device is connected to a three-axis displacement mechanism (not shown in the figure), and the tool handle 1 is driven to translate along the X, Y and Z axes through the three-axis displacement mechanism. The No. 2 port 11 of the T-tube 7 is connected to a negative pressure generator (not shown in the figure), and the expansion cover 6 can be lifted and lowered outside the threaded cutter head 2 in the vertical direction through the lifting tube 4. When the No. 1 spring 5 releases its elastic force to drive the expansion cover 6 to descend, the expansion cover 6 will drive the slide tube 15 to descend through the connecting bend 17. After the slide tube 15 descends, the valve pin 14 provided at the upper end of the slide tube 15 will block the No. 1 port 10. At the same time, the slide rod 18 connected to the slide tube 15 will drive the plug 19 to descend relative to the storage tank 8. At this time, the discharge port 9 is in an open state. When the threaded cutter head 2 follows the tool handle 1 to descend to mill the workpiece, the expansion cover 6 will conflict with the top of the workpiece (at this time, the expansion cover 6 is stationary relative to the ground, and the tool handle 1 continues to descend). Then, as the tool handle 1 descends , the expansion housing 6 will compress the No. 1 spring 5, so that the No. 1 spring 5 generates elastic force, and at the same time the slide tube 15 will slide upward relative to the valve tube 13. During this process, the slide tube 15 will contact the valve pin 14, so that the valve pin 14 will be away from the No. 1 port 10, and the venting notch 16 will correspond to the No. 1 port 10. When the slide tube 15 slides upward, the slide rod 18 connected to the slide tube 15 will drive the plug 19 upward to block the discharge port 9. Finally, in the process of the threaded cutter head 2 milling the workpiece, the No. 1 port 10 is in an open state and the discharge port 9 is in a blocked state. Thereafter, the negative pressure generator ( The second port 11 generates negative pressure when the milling tool 10 is started (not shown in the figure), and the flying chips blocked by the expansion cover 6 will enter the T-tube 7 through the connecting elbow 17, the slide pipe 15 and the first port 10 in sequence due to the suction force of the negative pressure. The chips entering the T-tube 7 will be sucked toward the second port 11. At this time, the chips are blocked by the material separation mesh plate 12 to prevent the chips from being discharged from the second port 11. When the milling tool completes the current milling work, the tool handle 1 will move horizontally to the next milling position on the workpiece after rising. Then, during the rising process of the tool handle 1, the slide pipe 15 will slide downward relative to the valve pipe 13, and the slide rod 1 8 will drive the plug 19 to descend relative to the storage tank 8. At this time, the No. 1 port 10 is blocked, the discharge port 9 is opened, and the negative pressure generator (not shown in the figure) is closed. Then, the debris located in the T-tube 7 will fall into the storage tank 8 from the discharge port 9 by gravity. In summary, whenever the threaded cutter head 2 follows the tool handle 1 to descend to mill the workpiece, the flying chips generated will be sucked into the T-tube 7 from the expansion cover 6. Whenever the tool handle 1 rises, the debris that falls into the T-tube 7 will fall downward from the T-tube 7 into the storage tank 8. When the storage tank 8 is full of debris, the storage tank 8 is removed to clean the debris.

[0020] In order to show how the lifting tube 4 is slidably connected to the fixing base 3, the following features are provided: The fixing seat 3 includes a No. 1 ring 20 and a No. 2 ring 21. The No. 1 ring 20 is coaxially sleeved on the lower end of the handle 1, and the No. 2 ring 21 is arranged directly below the No. 1 ring 20. A plurality of connecting rods 22 equidistantly distributed along the circumferential direction of the No. 1 ring 20 are arranged between the No. 1 ring 20 and the No. 2 ring 21. A connecting sleeve 23 is rotated inwardly of the No. 2 ring 21. The upper end of the lifting tube 4 passes through the connecting sleeve 23 upward, and the lifting tube 4 is sleeved on the outside of the threaded cutter head 2. A No. 1 convex ring 24 is formed on the top of the lifting tube 4, and a No. 2 convex ring 25 is formed on the inner wall of the connecting sleeve 23, and the No. 1 convex ring 24 is downwardly in conflict with the No. 2 convex ring 25.

[0021] The No. 2 circular ring 21 is connected to the No. 1 circular ring 20 through a plurality of connecting rods 22, so that the No. 1 circular ring 20 and the No. 2 circular ring 21 form an integrated structure. When installing the lifting tube 4, the No. 1 circular ring 20 is first fixed on the outer wall of the tool handle 1. At this time, the No. 2 circular ring 21 will be sleeved on the outside of the threaded cutter head 2. When the No. 1 circular ring 20 is fixed, the lifting tube 4 is inserted into the connecting sleeve 23. During this process, the No. 1 convex ring 24 is downwardly mounted on the No. 2 convex ring 25. After the lifting tube 4 is inserted into the connecting sleeve 23, the connecting sleeve 23 is upwardly screwed into the No. 2 circular ring 21. When the connecting sleeve 23 is connected to the No. 2 circular ring 21, the installation of the lifting tube 4 is completed. At this time, the lifting tube 4 is limited by the cooperation of the No. 1 convex ring 24 and the No. 2 convex ring 25 to limit the descending stroke, so as to prevent the lifting tube 4 from slipping out of the connecting sleeve 23.

[0022] To show how spring 5 is installed, the following features are set: The small-diameter end of the expansion cover 6 faces upward, and a vertically upward columnar sleeve 26 is coaxially formed on the small-diameter end of the expansion cover 6. The lower end of the lifting tube 4 is downwardly inserted into the columnar sleeve 26, and the lifting tube 4 is fixedly connected to the columnar sleeve 26. The No. 1 spring 5 is vertically sleeved outside the lifting tube 4, and the two ends of the No. 1 spring 5 are respectively in conflict with the bottom of the connecting sleeve 23 and the top of the columnar sleeve 26, and a dynamic sealing ring 27 is embedded in the connecting sleeve 23.

[0023] In the initial state, the No. 1 spring 5 releases its elastic force, and the cylindrical sleeve 26 will be displaced downward by the No. 1 spring 5, so that the expansion cover 6 will drive the lifting tube 4 to descend until the No. 1 convex ring 24 on the lifting tube 4 collides downward with the No. 2 convex ring 25. When the tool handle 1 descends for milling, the expansion cover 6 will first collide with the workpiece, so that the expansion cover 6 will compress the No. 1 spring 5 upward, and the No. 1 spring 5 will generate elastic force. Then when the tool handle 1 rises, the elastic force of the No. 1 spring 5 will drive the expansion cover 6 to descend again.

[0024] In order to show how the valve pin 14 and the slide tube 15 are installed, the following features are set: The outer wall of the valve tube 13 is formed with a horizontal rotation interface 28 (such as Fig.11 As shown in the figure, the rotary interface 28 is rotatably connected to the No. 1 port 10, both ends of the valve tube 13 are open structures, the upper end of the slide tube 15 is an open structure, and the lower end of the slide tube 15 is a closed structure. There are two connecting elbows 17, and the two ends of each connecting elbow 17 are respectively connected to the outer wall of the expansion cover 6 and the lower end of the slide tube 15. A sealing plug 29 is fixedly provided on the top of the valve tube 13, and a vertical No. 2 spring 30 is provided in the upper end of the valve tube 13. The two ends of the No. 2 spring 30 are respectively in conflict with the sealing plug 29 and the top of the valve pin 14, and the bottom of the valve pin 14 is in conflict with the top of the slide tube 15.

[0025] When the tool handle 1 rises, the expansion housing 6 will descend relative to the tool handle 1. During this process, the No. 2 spring 30 will push the valve pin 14 downward through its elastic force. Finally, when the expansion housing 6 is separated from the workpiece, the valve pin 14 will hover at the rotary interface 28. At this time, the No. 1 port 10 is blocked by the valve pin 14. When the tool handle 1 descends, the expansion housing 6 drives the slide tube 15 to rise relative to the valve tube 13 through the connecting bend 17. At this time, the slide tube 15 will resist the valve pin 14 upward, so that the valve pin 14 rises and compresses the No. 2 spring 30. When the tool handle 1 stops descending, the ventilation notch 16 on the slide tube 15 will correspond to the rotary interface 28. At this time, the valve tube 13 and the T-tube 7 are in a connected state. Then, when the No. 2 port 11 generates negative pressure, the debris located in the expansion housing 6 will enter the T-tube 7 through the connecting bend 17, the slide tube 15 and the valve tube 13 in turn.

[0026] In order to facilitate the debris in the T-tube 7 to slide toward the discharge port 9 by itself, the following features are provided: The outer wall of the T-shaped tube 7 is formed with two arc-shaped extension portions 31 (such as Figure 1 As shown in the figure, one arc-shaped extension part 31 is located between the No. 1 passage 10 and the discharge port 9, and the other arc-shaped extension part 31 is located between the No. 2 passage 11 and the discharge port 9. Two arc-shaped guide grooves 32 are provided on the inner wall of the T-shaped tube 7, and the two arc-shaped guide grooves 32 correspond to the two arc-shaped extension parts 31 respectively. A No. 3 circular ring 33 is fixedly provided on the outer wall of the handle 1, and an L-shaped rod 34 fixedly connected to the outer wall of the T-shaped tube 7 is formed on the No. 3 circular ring 33.

[0027] The T-tube 7 is connected to the tool handle 1 through an L-shaped rod 34 and a No. 3 ring 33, so that the T-tube 7 can perform three-axis displacement with the tool handle 1. When the No. 2 port 11 generates negative pressure suction, the debris in the expansion cover 6 will be sucked into the T-tube 7. At this time, the separation mesh plate 12 is used to prevent the debris from being discharged from the No. 2 port 11. When the No. 2 port 11 loses the negative pressure suction, the debris will slide downward along the arc-shaped guide groove 32 beside the No. 2 port 11, and finally the debris will fall downward from the discharge port 9 into the storage tank 8.

[0028] In order to facilitate the cleaning of the debris in the storage tank 8, the following features are provided: The storage tank 8 is arranged vertically (such as Fig.12 As shown), both ends of the storage tank 8 are open structures, the upper end of the storage tank 8 is fixedly connected to the discharge port 9, and the lower end of the storage tank 8 is fixedly provided with a circular blocking cover 35, and the top of the blocking cover 35 is formed with a plurality of elastic clips 36 evenly distributed along the circumferential direction of the blocking cover 35, and the inner wall of the lower end of the storage tank 8 is provided with a circle of annular grooves 37 for the elastic clips 36 to be embedded.

[0029] During the process of disassembling and assembling the blocking cover 35, the blocking cover 35 is fixed to the lower end of the storage tank 8 by the cooperation of the elastic clip 36 and the annular groove 37. When the debris falls downward into the storage tank 8 through the discharge port 9, the blocking cover 35 is used to prevent the debris in the storage tank 8 from falling out from the lower end of the storage tank 8. When the storage tank 8 is full of debris, the blocking cover 35 can be pulled out.

[0030] In order to show how the slide bar 18 is slidably connected to the storage tank 8, the following features are provided: A circular hole 38 is formed at the center of the baffle 35, and a rubber ring 39 is embedded in the circular hole 38. A horizontal support rod 40 is fixed on the outer wall of the lower end of the slide tube 15, and a vertical sleeve 41 (such as Figure 8 As shown in the figure, the upper end of the sleeve 41 passes through the rubber ring 39 and extends into the storage tank 8, the lower end of the slide bar 18 is inserted downward into the sleeve 41, and a vertical No. 3 spring 42 is provided in the sleeve 41. The two ends of the No. 3 spring 42 respectively conflict with the bottom of the slide bar 18 and the inner bottom wall of the sleeve 41, the plug 19 is conical, and the small-diameter end of the plug 19 faces upward, and a conical groove 43 matching with the plug 19 is formed on the inner wall of the upper end of the storage tank 8.

[0031] When the tool handle 1 rises, the expansion housing 6 will drop relative to the tool handle 1, so that the valve pin 14 will block the No. 1 port 10. At the same time, the slide tube 15 will drive the sleeve 41 to drop relative to the storage tank 8 through the support rod 40. During this process, the slide rod 18 inserted into the sleeve 41 will drive the plug 19 to drop relative to the storage tank 8, so that the discharge port 9 will be in an open state. When the tool handle 1 drops, the expansion housing 6 drives the slide tube 15 to rise by contacting with the workpiece. At this time, the ventilation notch 16 on the slide tube 15 will contact the rotary interface 28. Correspondingly, at the same time, the sleeve 41 will drive the slide bar 18 upward. During this process, the plug 19 arranged on the top of the slide bar 18 will gradually approach the conical groove 43, and finally the plug 19 will be embedded upward into the conical groove 43 to block the discharge port 9. In the process of the slide bar 18 rising, the plug 19 will be embedded upward into the conical groove 43 before the tool handle 1 stops descending. After the slide bar 18 stops rising, the sleeve 41 provides a resisting force through the No. 3 spring 42, so as to ensure that the discharge port 9 is completely blocked by the plug 19 during milling.

[0032] A method for using a distribution cabinet end cover processing milling device, the method comprising the following steps: S1, driving the tool holder 1 to descend to mill the workpiece; During actual use, the tool handle 1 of the device is connected to a three-axis displacement mechanism (not shown in the figure), which drives the tool handle 1 to translate along the X, Y and Z axes. A negative pressure generator (not shown in the figure) is connected to the No. 2 port 11 of the T-shaped tube 7, and the expansion cover 6 can be lifted and lowered outside the threaded cutter head 2 in the vertical direction through the lifting tube 4. When the No. 1 spring 5 releases its elastic force to drive the expansion mouth 6 to descend, the expansion mouth 6 will drive the slide tube 15 to descend through the connecting elbow 17. After the slide tube 15 descends, the valve pin 14 arranged at the upper end of the slide tube 15 will block the No. 1 opening 10. At the same time, the slide rod 18 connected to the slide tube 15 will drive the plug 19 to descend relative to the storage tank 8. At this time, the discharge port 9 is in an open state. When the threaded cutter head 2 follows the tool handle 1 to descend to mill the workpiece, the expansion mouth 6 will conflict with the top of the workpiece. Then, as the tool handle 1 descends, the expansion mouth 6 will compress the No. 1 spring 5, so that the No. 1 spring 5 generates elastic force. At the same time, the slide tube 15 will slide upward relative to the valve tube 13. During this process, the valve tube 13 will conflict with the valve pin 14, so that the valve pin 14 will move away from No. 1 port 10, and the vent notch 16 will correspond to the No. 1 port 10. When the slide tube 15 slides upward, the slide rod 18 connected to the slide tube 15 will drive the plug 19 upward to block the discharge port 9. Finally, in the process of the threaded cutter head 2 milling the workpiece, the No. 1 port 10 is in an open state and the discharge port 9 is in a blocked state. Thereafter, the negative pressure generator (not shown in the figure) is started, and the No. 2 port 11 generates negative pressure. Then, the flying chips blocked by the expansion cover 6 will enter the T-tube 7 through the connecting elbow 17, the slide tube 15 and the No. 1 port 10 in turn due to the negative pressure suction force. The chips entering the T-tube 7 will be sucked toward the No. 2 port 11. At this time, the chips are blocked by the partition mesh plate 12 to prevent the chips from being discharged from the No. 2 port 11.

[0033] S2, driving the tool handle 1 to rise and move the tool handle 1 horizontally to the next milling position on the workpiece; When the milling tool completes the current milling work, the tool handle 1 will move horizontally to the next milling position of the workpiece after rising. Then, during the rising process of the tool handle 1, the slide tube 15 will slide downward relative to the valve tube 13, and the slide rod 18 will drive the plug 19 to descend relative to the storage tank 8. At this time, the No. 1 port 10 is blocked, the discharge port 9 is opened, and the negative pressure generator (not shown in the figure) is closed. Then the debris in the T-tube will fall into the storage tank 8 from the discharge port 9 by gravity. In summary, whenever the threaded cutter head 2 follows the tool handle 1 to descend to mill the workpiece, the flying chips generated will be sucked into the T-tube 7 from the expansion housing 6. Whenever the tool handle 1 rises, the debris falling into the T-tube 7 will fall downward from the T-tube 7 into the storage tank 8. When the storage tank 8 is full of debris, the storage tank 8 is removed to clean the debris.

[0034] S3, repeat steps S1 and S2 in a loop until the milling of the current workpiece is completed.

[0035] When the debris falls downward into the storage tank 8 through the discharge port 9, the blocking cover 35 is used to prevent the debris in the storage tank 8 from falling out from the lower end of the storage tank 8. When the debris in the storage tank 8 is full, the blocking cover 35 can be pulled out.

[0036] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
