[0031] like Figure 1When in use, the end cover 54 on the tray 4 is placed on a lathe 3 through a transfer piece to process the end face + external thread of the end cover 54. After processing, the end cover 54 is placed on another lathe 3 through a transfer piece to process the rear end face + end hole. After the drilling is completed, the processed rear end cover 54 is placed on a cleaning piece through a transfer piece, and the residual coolant and waste on the processed rear end cover 54 can be cleaned through the cleaning piece. After the cleaning is completed, the cleaned end cover 54 is placed on the collection tray 5 through the transfer piece for collection. There is no need to manually clean the residual coolant on the end cover 54 and the waste adhered to the end cover 54 by the coolant, which saves time and effort.

[0032] like Figure 1 and Figure 2 The transfer member includes a slide groove 6 horizontally arranged at the top of the fixed frame 1, and a slider 7 is horizontally slidably connected in the slide groove 6, a first screw rod 8 is rotated between the left and right groove walls of the slide groove 6, and one end of the first screw rod 8 passes through the slider 7 and is threadedly connected to the slider 7, a first motor 9 for driving the first screw rod 8 to rotate is provided on the fixed frame 1, the first screw rod 8 is arranged along the length direction of the slide groove 6, a support plate 10 is horizontally provided at the top of the slider 7, and a rectangular frame 12 is provided at the end of the support plate 10 away from the slider 7, a slide rod 13 is vertically slidably connected in the rectangular frame 12, and a pneumatic clamp 14 for grabbing the end cover 54 is provided at the bottom end of the slide rod 13, a rack 15 is provided on one side of the slide rod 13 along the length direction of the slide rod 13, a first servo motor 16 is provided at the top of the rectangular frame 12, and a driving gear 17 meshing with the rack 15 is provided at one end of the rotating shaft of the first servo motor 16.

[0033] like Figure 1 and Figure 2 , by turning on the first motor 9, the rotating shaft of the first motor 9 drives the first screw rod 8 to rotate. At this time, because one end of the first screw rod 8 passes through the slider 7 and is threadedly connected to the slider 7, when the first screw rod 8 rotates, it can drive the slider 7 to move horizontally in the slide groove 6. At this time, the support plate 10, the rectangular frame 12, the slide rod 13, the pneumatic clamping jaws 14, the rack 15, the first servo motor 16 and the driving gear 17 will move with the slider 7. At this time, the pneumatic clamping jaws 14 can move back and forth above the tray 4, the collection tray 5, the cleaning piece and the two lathes 3. When the pneumatic clamping jaws 14 move horizontally to a suitable position, the first servo motor 16 is turned on, and the rotating shaft of the first servo motor 16 drives the driving gear 17 to rotate. At this time, the driving gear 17 drives the slide rod 13 to move vertically on the rectangular frame 12 through the rack 15 meshing therewith;

[0034] At this time, the end cover 54 on the tray 4 can be clamped and placed on the lathe 3 for processing through the pneumatic clamping jaws 14 that move horizontally and vertically. After processing, the end cover 54 is clamped and placed on the cleaning piece for cleaning. After cleaning, it is placed on the collection tray 5 for collection. It is simple and convenient to use.

[0035] like Figure 1 and Figure 2 and Figure 3 A sliding groove 18 is horizontally provided at the top of the placement table 2, and a sliding plate 19 is horizontally slidably connected in the sliding groove 18, a second screw rod 20 is rotatably connected between the front and rear side groove walls of the sliding groove 18, and one end of the second screw rod 20 passes through the sliding plate 19 and is threadedly connected to the sliding plate 19, the second screw rod 20 is arranged along the length direction of the sliding groove 18, a second motor 21 for driving the second screw rod 20 to rotate is provided on the placement table 2, a moving plate 22 is horizontally provided at the top of the sliding plate 19, the tray 4 and the collecting tray 5 are both placed on the top of the moving plate 22, and the cleaning piece is located on one side of the moving plate 22, The purpose of this arrangement is that by turning on the second motor 21, the rotating shaft of the second motor 21 drives the second screw rod 20 to rotate. At this time, because one end of the second screw rod 20 passes through the sliding plate 19 and is threadedly connected to the sliding plate 19, when the second screw rod 20 rotates, it can drive the sliding plate 19 to move back and forth in the sliding groove 18. At this time, the movable plate 22, the tray 4 and the collecting tray 5 will move with the sliding plate 19. At this time, the position of the tray 4 and the collecting tray 5 can be adjusted, so that the pneumatic clamp 14 can clamp the end cover 54 on the tray 4 or place the processed and cleaned end cover 54 on the collecting tray 5.

[0036] like Figure 1 and Figure 2 and Figure 4 and Figure 5 The cleaning part includes a fixed plate 23 arranged on the upper left side of the placement table 2, and a vertical plate 24 is vertically arranged on the top of the fixed plate 23, a barrel 25 is horizontally arranged on the side of the vertical plate 24 close to the placement table 2, and the barrel mouth of the barrel 25 faces the vertical plate 24, and a coaxial retaining ring 26 is arranged on the outer wall of the barrel 25, and a first cleaning area 27 and a second cleaning area 28 located on the right side of the retaining ring 26 are arranged on the outer wall of the barrel 25, and the second cleaning area 28 is close to the retaining ring 26, and a plurality of groups of first air ducts connected to the outer wall of the barrel 25 are obliquely arranged on the inner wall of the barrel 25, and each group of first air ducts is connected to the first cleaning area 27 and distributed along the length direction of the barrel 25, and each group of first air ducts includes a plurality of first connecting pipes 29, and each first connecting pipe 29 is provided. The through pipes 29 are evenly distributed along the circumference of the barrel 25, and one end of each first connecting pipe 29 located in the barrel 25 is inclined toward the direction close to the retaining ring 26. A plurality of groups of second air ducts connected to the outer wall of the barrel 25 are inclined on the inner wall of the barrel 25, and each group of second air ducts is connected to the second cleaning area 28 and distributed along the length direction of the barrel 25. Each group of second air ducts includes a plurality of second connecting pipes 30, and each second connecting pipe 30 is evenly distributed along the circumference of the barrel 25. One end of each second connecting pipe 30 located in the barrel 25 is inclined toward the direction away from the retaining ring 26. An air intake pipe 31 connected to the barrel 25 is provided on the side of the vertical plate 24 facing away from the barrel 25, and an electromagnetic valve 32 is provided on the air intake pipe 31.

[0037] like Figure 1 and Figure 2 and Figure 4 and Figure 5 , connect the air inlet pipe 31 with the external high-pressure air pipe. After the end cover 54 is processed, the rear end cover 54 is clamped by the pneumatic clamp 14 to the side of the plug barrel 25 away from the vertical plate 24, and the hole on the end cover 54 is aligned with the plug barrel 25. Then, the solenoid valve 32 is opened. At this time, the airflow will enter the plug barrel 25 from the air inlet pipe 31 and blow out obliquely from the first connecting pipes 29 and the second connecting pipes 30 on the plug barrel 25. Then, the pneumatic clamp 14 is moved horizontally, so that the bottom of the plug barrel 25 passes through the processed holes on the end cover 54 until one side of the end cover 54 contacts the retaining ring 26. At this time, the end cover 54 passes through the first cleaning area 27. When one side of the end cover 54 contacts the retaining ring 26, the end cover 54 will be located in the second cleaning area 28. Then, the pneumatic clamp 14 is released and the pneumatic clamp 14 is moved in the direction away from the retaining ring 26.

[0038] When the bottom of the insert barrel 25 passes through the hole on the end cover 54 and the end cover 54 approaches the first cleaning area 27, the wind blown out from each first connecting pipe 29 can blow the side of the end cover 54 facing the baffle ring 26, so that the coolant and waste materials on the side of the end cover 54 facing the baffle ring 26 are blown off from the end cover 54, and at the same time, the waste materials or coolant splashed to the side of the baffle ring 26 away from the vertical plate 24 can be blown off from the baffle ring 26 by the wind blown out from the second connecting pipe 30;

[0039] When the end cover 54 passes through the first cleaning area 27, the coolant and waste materials on the inner wall of the hole on the end cover 54 can be blown away from the inner wall of the hole on the end cover 54 by the wind blown out from each first connecting pipe 29. When the end cover 54 is located in the second cleaning area 28 and contacts the retaining ring 26, the wind blown out from each second connecting pipe 30 can blow the side of the end cover 54 away from the retaining ring 26, so that the coolant and waste materials on the side of the end cover 54 away from the retaining ring 26 can be blown away from the end cover 54.

[0040] When one side of the end cover 54 contacts the retaining ring 26, the pneumatic clamp 14 is released, and then the pneumatic clamp 14 moves away from the retaining ring 26 until the pneumatic clamp 14 moves to the first cleaning area 27, and then the clamping end of the pneumatic clamp 14 is brought close to the insert barrel 25. At this time, the coolant and waste on the clamping end of the pneumatic clamp 14 can be blown off from the clamping end of the pneumatic clamp 14 by the wind blown out from the first connecting pipe 29. After the coolant and waste on the clamping end of the pneumatic clamp 14 are blown off, the pneumatic clamp 14 continues to move away from the retaining ring 26 until the pneumatic clamp 14 is located on the side of the insert barrel 25 away from the vertical plate 24, and then the end cover 54 is waited for cleaning;

[0041] When the end cover 54 is cleaned, the pneumatic clamp 14 approaches the retaining ring 26 until the pneumatic clamp 14 is moved to the end cover 54 on the barrel 25, and then the pneumatic clamp 14 clamps the cleaned end cover 54 on the barrel 25, and then the pneumatic clamp 14 drives the end cover 54 away from the retaining ring 26 until the cleaned end cover 54 is removed from the barrel 25, and then the end cover 54 is placed on the collection tray 5. In each group of the first air duct and the second air duct, the number of the first connecting tube 29 and the second connecting tube 30 can be four, which is simple and convenient to use.

[0042] One end of the air intake pipe 31 away from the vertical plate 24 is connected to an air pump (not shown in the figure) through a hose (not shown in the figure), and the air pump is arranged at the bottom end of the vertical plate 24. At this time, the air flow can be blown into the air intake pipe 31 through the air pump and the hose, and there is no need to connect the air intake pipe 31 to the external high-pressure air pipe.

[0043] like Figure 5 The insert barrel 25 is rotatably connected to the vertical plate 24, and a first gear 33 is coaxially provided on the outer wall of the insert barrel 25. A rotating motor 34 is provided at one end of the vertical plate 24 close to the insert barrel 25, and a second gear 35 meshing with the first gear 33 is provided on the rotating shaft of the rotating motor 34. The first gear 33, the second gear 35 and the rotating motor 34 are all located between the retaining ring 26 and the vertical plate 24. The purpose of this arrangement is that when the bottom of the insert barrel 25 passes through the hole on the end cover 54 until the end cover 54 contacts the retaining ring 26, the second gear 35 is driven to rotate by the rotating motor 34, and the second gear 35 drives the insert barrel 25 to rotate on the vertical plate 24 through the first gear 33 meshing therewith. At this time, the rotating insert barrel 25 can improve the effect of the first connecting pipe 29 and the second connecting pipe 30 on blowing and cleaning the end cover 54 when the end cover 54 passes through the first cleaning area 27 on the insert barrel 25 and is located in the second cleaning area 28.

[0044] like Figure 4 and Figure 5The vertical plate 24 is provided with a blowing member for blowing and cleaning the arc surface on the outer wall of the end cover 54, and the blowing member includes a barrel 36 arranged on the side of the vertical plate 24 away from the plug barrel 25, and the barrel 36 is coaxial with the plug barrel 25, and the vertical plate 24 is provided with a circular connecting groove 37 for connecting the plug barrel 25 with the barrel 36, and the air inlet pipe 31 is arranged on the side of the barrel 36 away from the vertical plate 24 and communicates with the barrel 36, and the top of the fixed plate 23 is provided with two opposite side plates 38, and the two side plates 38 are rotatably connected with a rotating shaft 39, and the vertical plate 24 is vertically arranged On the rotating shaft 39, a second servo motor 40 for driving the rotating shaft 39 to rotate is provided on one of the side plates 38, a horizontal tube 41 is horizontally provided at one end of the vertical plate 24 close to the insertion barrel 25, and the horizontal tube 41 is located above the insertion barrel 25, an L-shaped connecting tube 42 connected to the barrel 36 is provided at the top of the outer wall of the barrel 36, and the end of the connecting tube 42 away from the barrel 36 is connected to the horizontal tube 41, the end of the horizontal tube 41 away from the vertical plate 24 is sealed by a cover plate 43, and a plurality of exhaust ports 44 facing the insertion barrel 25 are opened at the bottom end of the horizontal tube 41.

[0045] like Figure 4 and Figure 5 , the airflow enters the barrel 36 from the air inlet pipe 31, and the airflow in the barrel 36 enters the plug barrel 25 and the connecting pipe 42 respectively. At this time, the airflow in the connecting pipe 42 will enter the horizontal pipe 41, and then blow out from the exhaust port 44 on the horizontal pipe 41. When the end cover 54 is located on the plug barrel 25 and contacts one side of the retaining ring 26, the airflow blown out from the exhaust port 44 on the horizontal pipe 41 will contact the arc surface on the outer wall of the end cover 54;

[0046] After the end cover 54 on the insert barrel 25 contacts the baffle ring 26, and the end cover 54 is respectively close to and away from the baffle ring 26 and the inner wall of the hole on the end cover 54 is cleaned, the second servo motor 40 is turned on, and the rotating shaft of the second servo motor 40 drives the rotating shaft 39 to rotate 90 degrees counterclockwise. At this time, the vertical plate 24 rotates with the rotating shaft 39. When the rotating shaft 39 rotates 90 degrees counterclockwise, as shown in FIG. Figure 6 and Figure 7, the vertical plate 24 will be in a horizontal state, and the plug barrel 25 and the horizontal tube 41 will be vertical. At this time, the cooperation between the rotating motor 34, the second gear 35 and the first gear 33 will make the plug barrel 25 rotate on the vertical plate 24. At this time, the retaining ring 26 will rotate with the plug barrel 25. At this time, due to the influence of gravity, the end cover 54 on the plug barrel 25 will be pressed on the top of the retaining ring 26. When the retaining ring 26 and the plug barrel 25 rotate, the retaining ring 26 will drive the end cover 54 to rotate. At this time, the water The wind blown out of the exhaust port 44 on the flat pipe 41 can blow away the coolant and waste on the arc surface of the outer wall of the end cover 54. The retaining ring 26 is provided with an anti-skid pad 53 in contact with the end cover 54. The anti-skid pad 53 can increase the friction resistance between the retaining ring 26 and the end cover 54, so that the retaining ring 26 can drive the end cover 54 to rotate. After the coolant and waste on the arc surface of the outer wall of the end cover 54 are blown away, the rotating shaft 39 rotates 90 degrees clockwise, so that the vertical plate 24 rotates back to its original position. Figure 4 At this time, the vertical plate 24 is vertical, the insert barrel 25 is horizontal, and then the end cap 54 is clamped by the pneumatic clamp 14, and then the pneumatic clamp 14 moves upward to separate the inner wall of the hole on the end cap 54 from the outer wall of the insert barrel 25, and then the end cap 54 is removed from the insert barrel 25;

[0047] When the end cover 54 is removed from the insert barrel 25, the pneumatic clamp 14 is first moved upward to separate the inner wall of the hole on the end cover 54 from the outer wall of the insert barrel 25, thereby reducing the wear between the outer wall of the insert barrel 25 and the inner wall of the hole on the end cover 54 when the end cover 54 is removed, and the use is simple and convenient.

[0048] like Figure 5 and Figure 8A ring body 45 is coaxially arranged in the barrel 25 near the barrel mouth of the barrel 25, the outer wall of the ring body 45 is fixedly connected to the inner wall of the barrel 25, and an L-shaped conduit 46 is arranged on the side of the ring body 45 away from the barrel bottom of the barrel 25, and the conduit 46 is communicated with the barrel 25 through the ring body 45, and a circular ring 47 is arranged on the side of the vertical plate 24 away from the barrel 25, and the circular ring 47 is coaxial with the barrel 25, and the end of the conduit 46 away from the ring body 45 passes through the connecting groove 37 and is located in the circular ring 47, and the pipe opening of the conduit 46 away from the ring body 45 faces downward and contacts with the inner wall of the circular ring 47, and a side groove 48 is arranged at the bottom end of the outer wall of the circular ring 47, and the side groove 48 corresponds to the pipe opening of the conduit 46 away from the ring body 45, and the inner wall of the circular ring 47 is close to the barrel 25. A baffle plate 49 is provided at one end of the side groove 48, and the baffle plate 49 is located at the rear side of the conduit 46 and contacts the outer wall of the conduit 46. The purpose of this arrangement is that when the vertical plate 24 is vertical, the airflow in the barrel 36 enters the conduit 46 from the side groove 48, and then enters the plug barrel 25 from the conduit 46 through the ring body 45. When the plug barrel 25 rotates, the plug barrel 25 drives the conduit 46 to rotate in the ring 47 through the ring body 45. When the vertical plate 24 is vertical, the rotation direction of the plug barrel 25 is clockwise. At this time, the conduit 46 drives the ring 47 to rotate through the baffle plate 49. At this time, when the vertical plate 24 is vertical and the plug barrel 25 rotates clockwise, the conduit 46 and the side groove 48 on the ring 47 always correspond to each other.

[0049] like Figure 6 and Figure 7 When the rotating shaft 39 rotates 90 degrees counterclockwise to make the vertical plate 24 horizontal, and the plug barrel 25 and the horizontal tube 41 vertical, the rotation direction of the plug barrel 25 is clockwise, and the conduit 46 will be separated from the baffle 49 and the side groove 48. At this time, the pipe opening of the conduit 46 away from the ring body 45 can be closed through the inner wall of the ring 47, thereby reducing the air flow of the conduit 46. At this time, the air pressure in the barrel 36, the connecting pipe 42 and the horizontal tube 41 will increase, thereby improving the cleaning effect of the airflow blown out from the exhaust port 44 on the arc surface of the outer wall of the end cover 54. When the conduit 46 rotates clockwise in the ring 47 until the outer wall of the conduit 46 contacts the side of the baffle 49 away from the side groove 48, as the conduit 46 rotates clockwise, the conduit 46 will drive the ring 47 to rotate clockwise through the baffle 49, which is simple and convenient to use.

[0050] like Figure 6 When the vertical board 24 rotates 90 degrees in the direction away from the placement table 2, a vertical rod 50 for supporting the vertical board 24 is vertically provided on the side of the top of the fixed plate 23 away from the vertical board 24. The purpose of this arrangement is to support the vertical board 24 rotated to the horizontal direction by the vertical rod 50, so as to reduce the downward bending of the end of the vertical board 24 away from the rotation axis 39 on the vertical board 24 after the vertical board 24 rotates to the horizontal direction.

[0051] like Figure 5A cover shell 51 is provided at one end of the vertical plate 24 close to the insertion barrel 25, and the first gear 33, the second gear 35 and the rotating motor 34 are all located in the cover shell 51. A round hole for one end of the insertion barrel 25 to pass through is opened on the cover shell 51, and a support ring 52 is sleeved on the outer wall of the insertion barrel 25, and the support ring 52 is fixedly connected to the outer wall of the cover shell 51 and is coaxial with the round hole. The purpose of this arrangement is that the rotating motor 34, the first gear 33 and the second gear 35 can be protected by the cover shell 51, and external impurities can be reduced from splashing between the first gear 33 and the second gear 35, thereby affecting the meshing of the first gear 33 and the second gear 35. By sleeved on the insertion barrel 25 and provided on the cover shell 51, the stability of the insertion barrel 25 during rotation can be improved, and it is simple and convenient to use.
