Its core structure and working principle play an important role in the needle punching reinforcement process. The components of the spindle box type needle punching machine include a spindle, a needle plate beam, etc. These components usually have complex shapes and structures. Through a numerical control milling machine, these components can be milled to form specific shapes and structures to meet different requirements.

[0005] When milling the spindle in the spindle box type needle punching machine components, usually, the spindle is a cylindrical blank before milling. And before milling, it is necessary to fix the cylindrical blank first. Then, the worker needs to manually place the cylindrical blank in the fixed area of the milling machine.

[0044] A combined material transfer assembly for sequentially placing a plurality of cylindrical blanks onto the electric chuck 11 is further provided on the workbench 1;

[0045] The combined material transfer assembly includes a support column 7 fixedly connected to one side of the upper end surface of the workbench 1. The upper end of the support column 7 is fixedly connected with a support ring 14. A plurality of first sliding rods 15 are radially distributed and slidably connected on the support ring 14. One end of the first sliding rod 15 is fixedly connected with a combined plate 23. An elastic cloth 22 is fixedly connected between adjacent two combined plates 23. One side of the support column 7 is fixedly connected with a second cylinder 17. The piston end of the second cylinder 17 is fixedly connected with a stop disk 18. The upper end surface of the stop disk 18 is flush with the lower end surface of the combined plate 23.

[0046] In this embodiment, as Figures 1 - 3 、 Figure 7 、 Figures 9 - 11 shown, one side of the lower end of the displacement frame 6 is threadedly connected with a first threaded rod 5. Both ends of the first threaded rod 5 are rotatably arranged on the workbench 1. A first motor 4 is fixedly connected to one side of the upper end surface of the workbench 1. The output end of the first motor 4 is fixedly connected with one end of the first threaded rod 5.

[0047] One side of the upper end surface of the lifting plate 9 is fixedly connected with a second motor 12. The output end of the second motor 12 is fixedly connected with one end of a rotating plate 10. One side of the upper end of the rotating plate 10 is fixedly connected with a third motor 13. The output end of the third motor 13 is fixedly connected with one side of the electric chuck 11.

[0048] One end of the first sliding rod 15 is rotatably provided with a first connecting rod 19. One end of the first connecting rod 19 is rotatably provided with a lifting ring 16. One side of the lifting ring 16 is threadedly connected with a fourth threaded rod 42. The lower end of the fourth threaded rod 42 is rotatably arranged on the support ring 14. A motor eight 24 is fixedly connected to one side of the support ring 14. The output end of the motor eight 24 is fixedly connected with one end of the fourth threaded rod 42.

[0049] Specifically, in the prior art, when milling the main shaft in the main shaft box type needle punching machine assembly, usually, the main shaft before milling is a cylindrical blank. And before milling, it is necessary to fix the cylindrical blank first. Then, workers need to manually place the cylindrical blank in the fixed area of the milling machine. When the number of cylindrical blanks to be milled is large, the number of times for workers to place the cylindrical blanks will increase accordingly, so the labor intensity is relatively high. Moreover, when using an automatic clamping structure to load the cylindrical blanks, if a plurality of cylindrical blanks are randomly stacked, it will cause the clamping structure to be difficult to identify and accurately clamp the cylindrical blanks, affecting the loading efficiency.

[0050] Therefore, to solve the above problems, in use, this embodiment is applied to a batch of cylindrical blanks with the same specifications; since multiple combined plates 23 and elastic cloth 22 form a funnel-shaped structure, the funnel-shaped structure is wider at the top and narrower at the bottom. The wider upper area serves as the feeding area, and the narrower lower area serves as the feeding channel, and the feeding channel is cylindrical; according to the diameter of the cylindrical blank, the motor eight 24 drives the threaded rod four 42 to rotate, so that the lifting ring 16 rises and falls. When the lifting ring 16 rises and falls, it will drive the sliding rod one 15 to slide on the support ring 14 through the connecting rod one 19, adjusting the distance between the multiple combined plates 23 and the axis of the support ring 14. At the same time, since the elastic cloth 22 is made of elastic material, the elastic cloth 22 will also deform and always be in a taut state until the diameter of the feeding channel is larger than the diameter of one cylindrical blank and smaller than the diameter of two cylindrical blanks.

[0051] Multiple cylindrical blanks are uniformly placed in the feeding area of the funnel-shaped structure. Under the action of gravity, the cylindrical blanks move downward. Since only one cylindrical blank can pass through the feeding channel at a time, multiple cylindrical blanks will be vertically arranged in the feeding channel, with the ends of adjacent cylindrical blanks in contact, and the lowermost cylindrical blank is blocked by the blocking plate 18.

[0052] At this time, the axis of the electric chuck 11 coincides with the axis of the support ring 14. The second cylinder 17 drives the stop disk 18 to move horizontally, so that the stop disk 18 no longer blocks the lowermost cylindrical blank. Then the cylindrical blank will fall onto the electric chuck 11, and the end of the cylindrical blank is clamped by the electric chuck 11. The electric chuck 11 is an existing clamping technology and will not be elaborated here. Then, under the action of the first cylinder 8, the electric chuck 11 is driven to descend, so that the clamped cylindrical blank gradually disengages from the blanking channel. And when the upper end of the clamped cylindrical blank is about to disengage from the blanking channel, the stop disk 18 is driven to reset to continue blocking the remaining cylindrical blanks in the blanking channel. At this time, the second motor 12 drives the rotating plate 10 to rotate by 90 degrees, so that the clamped cylindrical blank is in a horizontal state. The first motor 4 drives the first threaded rod 5 to rotate, so that the displacement frame 6 and the cylindrical blank move horizontally. The milling cutter 2 is aligned with the surface of the cylindrical blank. The milling cutter driver 20 is used to drive the milling cutter 2 to rotate. At the same time, the third motor 13 drives the electric chuck 11 to rotate, then the cylindrical blank rotates to adjust the angle of the cylindrical blank, and the milling cutter 2 is used to mill the surface of the cylindrical blank. And a collection container can be placed on the workbench 1. When a cylindrical blank is milled, the electric chuck 11 releases it, and then the milled cylindrical blank falls into the collection container. Then the above operations are repeated, so that multiple subsequent cylindrical blanks can fall onto the electric chuck 11 in sequence and be milled, thus realizing the automatic feeding of multiple cylindrical blanks, eliminating the process of manual feeding by workers, reducing the labor intensity of workers, and arranging the multiple randomly placed cylindrical blanks in an orderly manner, avoiding the situation that it is not easy to clamp the multiple randomly stacked cylindrical blanks, which in turn affects the feeding efficiency.

[0053] In this embodiment, as Figure 5 , Figure 6 , Figure 8 shown, anti-pressure components are also provided on the left and right combined plates 23;

[0054] The anti-pressure components include a groove plate 21 fixedly connected to one side of the combined plate 23. A threaded block 31 is slidably connected to the chute of the groove plate 21. One side of the threaded block 31 is fixedly connected to a third cylinder 33. The piston end of the third cylinder 33 is fixedly connected to a slide rail plate 26. A plurality of clamping blocks 28 are sleeved on the slide rail plate 26 and longitudinally arranged at equal intervals. The lowermost clamping block 28 is fixedly connected to the slide rail plate 26, and the remaining clamping blocks 28 are slidably connected to the slide rail plate 26. Bar-shaped through holes are provided on one side of the left and right combined plates 23, and the clamping blocks 28 can pass through the bar-shaped through holes.

[0055] One side of the threaded block 31 is threadedly connected to a third threaded rod 32. Both ends of the third threaded rod 32 are rotatably arranged on the groove plate 21. The lower end of the groove plate 21 is fixedly connected to a fifth motor 34. The output end of the fifth motor 34 is fixedly connected to one end of the third threaded rod 32.

[0056] Two connecting rods two 29 are rotatably arranged on one side of the lowermost and uppermost clamping blocks 28, and two connecting rods three 30 are rotatably arranged on one side of the remaining clamping blocks 28. One end of the connecting rod two 29 is rotatably connected to one end of the connecting rod three 30, and the ends of adjacent two connecting rods three 30 are rotatably connected. One side of the upper end of the slide rail plate 26 is fixedly connected with an electric push rod 27, and the piston end of the electric push rod 27 is fixedly connected with one side of the uppermost clamping block 28.

[0057] Specifically, in the above embodiment, in order to make each cylindrical blank accurately fall on the electric chuck 11, multiple cylindrical blanks are arranged longitudinally, and the ends of adjacent cylindrical blanks are in contact. This makes the mutual force between them more concentrated, and the pressure on the local part of the cylindrical blank will increase due to this concentrated pressure. Moreover, the cylindrical blank cannot disperse the pressure by adjusting its position as it does when stacked. When the milling time of a single cylindrical blank is long, the placement time of the cylindrical blanks in the blanking channel is also long. When the pressure on the cylindrical blank exceeds the yield strength for a long time, the material will undergo plastic deformation, thus affecting the quality of the cylindrical blank.

[0058] Therefore, to solve the above problems, when multiple cylindrical blanks are in the blanking channel, the motor five 34 drives the threaded rod three 32 to rotate to drive the threaded block 31 to slide up and down, so that the lowermost clamping block 28 is aligned with the lower cylindrical blank. Then, according to the length of the cylindrical blank, the electric push rod 27 is started. The electric push rod 27 drives the uppermost clamping block 28 to move. And, under the transmission of the connecting rod two 29 and the connecting rod three 30, multiple clamping blocks 28 slide on the slide rail plate 26 at the same time, and the distance between adjacent clamping blocks 28 changes, and the distance between adjacent two clamping blocks 28 always remains the same until all clamping blocks 28 are respectively aligned with different cylindrical blanks. Then, the two cylinders three 33 on both sides are started at the same time, so that the clamping blocks 28 on both sides pass through the strip-shaped through holes on the combined plate 23 and contact the cylindrical blank, and the cylindrical blank in the blanking channel can be clamped. Since the cylindrical blank in the blanking channel is clamped, the lower cylindrical blank will not be subjected to the pressure of the upper cylindrical blank, thus avoiding the situation that the cylindrical blank deforms due to the pressure exceeding its yield strength during the long-term stay in the blanking channel, which in turn affects its quality.

[0059] During blanking, just drive the clamping block 28 to release the cylindrical blank again. And, after one cylindrical blank falls, the clamping block 28 continues to clamp the remaining cylindrical blanks, so the cylindrical blank will only be under pressure for a short time, and the influence on deformation is small.

[0060] In this embodiment, as Figure 4 、 Figure 9 、 Figure 12 shown, a scraping and pushing assembly is further arranged on the combined plate 23;

[0061] The scraping and pushing assembly includes a surrounding plate 40 slidably connected to the upper end surface of the combined plate 23. One side of the surrounding plate 40 is in contact with the inner surface of the combined plate 23. A gear 44 is rotatably arranged on one side of the upper end of the surrounding plate 40. Tooth blocks are evenly arranged on the outer side of the upper end of the combined plate 23. The gear 44 meshes with the tooth blocks on the combined plate 23. A seventh motor 43 is fixedly connected to one side of the upper end of the surrounding plate 40. The output end of the seventh motor 43 is fixedly connected to the gear 44.

[0062] A middle extrusion assembly is further arranged on the support ring 14;

[0063] The middle extrusion assembly includes multiple synchronizing rods 25 slidably connected to the support ring 14. Two second sliding rods 36 are slidably connected to one side of the lower end of the synchronizing rod 25. A pressing rod 35 is fixedly connected to one end of the second sliding rod 36. A spring 37 is sleeved on one side of the second sliding rod 36. One end of the spring 37 is fixedly connected to the second sliding rod 36, and the other end is fixedly connected to the synchronizing rod 25. The synchronizing rod 25 and the first sliding rod 15 are connected by a telescopic rod 41.

[0064] An eccentric block 38 is rotatably arranged on one side of the bottom of the synchronizing rod 25. The eccentric block 38 is in contact with one side of the pressing rod 35. A sixth motor 39 is fixedly connected to one side of the bottom of the synchronizing rod 25. The output end of the sixth motor 39 is fixedly connected to the eccentric block 38.

[0065] Specifically, in the above embodiment, when the cylindrical blank is placed into the funnel-shaped structure, since the cylindrical blanks converge into the feeding channel, it is easy to get stuck due to the mutual extrusion of the cylindrical blanks, thus affecting the normal longitudinal arrangement of the cylindrical blanks;

[0066] Therefore, to solve the above problems, after the cylindrical blanks are placed between multiple combined plates 23 and the elastic cloth 22, the seventh motor 43 and the sixth motor 39 are started. The seventh motor 43 drives the gear 44 to rotate regularly back and forth, making the surrounding plate 40 move in a circular motion. When the surrounding plate 40 moves to the edge of the combined plate 23 and then returns to the initial position, the surrounding plate 40 can push the cylindrical blanks. At the same time, under the action of the telescopic rod 41, when the first sliding rod 15 moves, the synchronizing rod 25 will also move. And the pressing rod 35 always aims at the middle position of the elastic cloth 22. When the sixth motor 39 drives the eccentric block 38 to rotate, the eccentric block 38 continuously squeezes the pressing rod 35, and the pressing rod 35 squeezes the elastic cloth 22. Since the middle of the elastic cloth 22 is squeezed, the cylindrical blanks on the elastic cloth 22 will move due to the extrusion of the pressing rod 35, and a bulge is formed on one side of the elastic cloth 22. The cylindrical blanks are also easy to slide along the surface of the elastic cloth 22. Thus, with the cooperation of the surrounding plate 40 and the pressing rod 35, the cylindrical blanks between the combined plate 23 and the elastic cloth 22 continue to move, promoting the falling of the cylindrical blanks, and avoiding the situation that the cylindrical blanks are stuck between the combined plate 23 and the elastic cloth 22 and affecting their normal longitudinal arrangement.

[0067] Working principle: Since multiple combined plates 23 and elastic cloth 22 form a funnel-shaped structure, the funnel-shaped structure is wider at the top and narrower at the bottom. The wider area on the upper side serves as the feeding area, and the narrower area on the lower side serves as the discharging channel, and the discharging channel is cylindrical. According to the diameter of the cylindrical blank, the motor eight 24 drives the threaded rod four 42 to rotate, causing the lifting ring 16 to lift and lower. When the lifting ring 16 lifts and lowers, it will drive the sliding rod one 15 to slide on the support ring 14 through the connecting rod one 19, adjusting the distance between the multiple combined plates 23 and the axis of the support ring 14. At the same time, since the elastic cloth 22 is made of elastic material, the elastic cloth 22 will also deform and always be in a taut state until the diameter of the discharging channel is larger than the diameter of one cylindrical blank and smaller than the diameter of two cylindrical blanks. Multiple cylindrical blanks are uniformly placed in the feeding area of the funnel-shaped structure. Under the action of gravity, the cylindrical blanks move downward. Since only one cylindrical blank can pass through the discharging channel at a time, multiple cylindrical blanks will be vertically arranged in the discharging channel, with the ends of adjacent cylindrical blanks in contact, and the lowermost cylindrical blank is blocked by the blocking plate 18. At this time, the axis of the electric chuck 11 coincides with the axis of the support ring 14. The cylinder two 17 drives the blocking plate 18 to move horizontally, so that the blocking plate 18 no longer blocks the lowermost cylindrical blank, and then the cylindrical blank will fall onto the electric chuck 11. The electric chuck 11 clamps the end of the cylindrical blank. The electric chuck 11 is an existing clamping technology and will not be elaborated here. Then, under the action of the cylinder one 8, the electric chuck 11 is driven to descend, so that the clamped cylindrical blank gradually disengages from the discharging channel. And when the upper end of the clamped cylindrical blank is about to disengage from the discharging channel, the blocking plate 18 is driven to reset to continue blocking the remaining cylindrical blanks in the discharging channel. At this time, the motor two 12 drives the rotating plate 10 to rotate by 90 degrees, making the clamped cylindrical blank in a horizontal state. The motor one 4 drives the threaded rod one 5 to rotate, causing the displacement frame 6 and the cylindrical blank to move horizontally. The milling cutter 2 is aligned with the surface of the cylindrical blank. The milling cutter driver 20 is used to drive the milling cutter 2 to rotate. At the same time, the motor three 13 drives the electric chuck 11 to rotate, and then the cylindrical blank rotates to adjust the angle of the cylindrical blank. The surface of the cylindrical blank is milled by the milling cutter 2. And a collection container can be placed on the workbench 1. When the milling of one cylindrical blank is completed, the electric chuck 11 releases it, and then the milled cylindrical blank falls into the collection container. Then, the above operations are repeated, and subsequent multiple cylindrical blanks can be successively dropped onto the electric chuck 11 and milled, thus realizing the automatic feeding of multiple cylindrical blanks, eliminating the process of manual feeding by workers, reducing the labor intensity of workers, and turning the multiple randomly placed cylindrical blanks into a neatly arranged state, avoiding the situation that it is not easy to clamp the multiple randomly stacked cylindrical blanks, which in turn affects the feeding efficiency.When multiple cylindrical blanks are in the blanking channel, the motor five 34 drives the rotation of the threaded rod three 32 to drive the threaded block 31 to slide up and down, so that the lowermost clamping block 28 aligns with the lowermost cylindrical blank. Then, according to the length of the cylindrical blank, the electric push rod 27 is started. The electric push rod 27 drives the uppermost clamping block 28 to move. And, under the transmission of the connecting rod two 29 and the connecting rod three 30, multiple clamping blocks 28 slide on the slide rail plate 26 at the same time, and the distance between adjacent clamping blocks 28 changes, and the distance between adjacent two clamping blocks 28 always remains the same until all the clamping blocks 28 are respectively aligned with different cylindrical blanks. Then, the cylinders three 33 on both sides are started at the same time, so that the clamping blocks 28 on both sides pass through the strip-shaped through holes on the combined plate 23 and contact the cylindrical blanks, and the cylindrical blanks in the blanking channel can be clamped. Since the cylindrical blanks in the blanking channel are clamped, the lowermost cylindrical blank will not be pressed by the upper cylindrical blanks, thus avoiding the situation that the cylindrical blanks are deformed due to the pressure exceeding their yield strength after being in the blanking channel for a long time, which in turn affects their quality. During blanking, the clamping block 28 is driven to release the cylindrical blank again. And, after one cylindrical blank falls, the clamping block 28 continues to clamp the remaining cylindrical blanks, so the cylindrical blank will only be under pressure for a short time, and the influence on deformation is small. After the cylindrical blanks are placed between the multiple combined plates 23 and the elastic cloth 22, the motor seven 43 and the motor six 39 are started. The motor seven 43 drives the gear 44 to rotate regularly back and forth, so that the surrounding plate 40 makes a circular movement, and when the surrounding plate 40 moves to the edge of the combined plate 23 and returns to the initial position, the surrounding plate 40 can push the cylindrical blank. At the same time, under the action of the telescopic rod 41, when the sliding rod one 15 moves, the synchronous rod 25 will also be pushed to move, and the pressing rod 35 always aligns with the middle position of the elastic cloth 22. When the motor six 39 drives the eccentric block 38 to rotate, the eccentric block 38 continuously squeezes the pressing rod 35, and the pressing rod 35 squeezes the elastic cloth 22. Since the middle of the elastic cloth 22 is squeezed, the cylindrical blank on the elastic cloth 22 will move due to the squeezing of the pressing rod 35, and a bulge is formed on one side of the elastic cloth 22, and the cylindrical blank is also easy to slide along the surface of the elastic cloth 22. Thus, with the cooperation of the surrounding plate 40 and the pressing rod 35, the cylindrical blanks between the combined plate 23 and the elastic cloth 22 continue to move, promoting the falling of the cylindrical blanks, and avoiding the situation that the cylindrical blanks are stuck between the combined plate 23 and the elastic cloth 22 and affecting their normal longitudinal arrangement.
