Specific embodiments

[0031] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0032] Embodiment 1, refer to Figures 1 - 5, A turning device for metal pipe fittings, comprising a lathe body 1. A placement bin 3 is provided on the back of the lathe body 1, and lifting mechanisms are provided on both sides of the placement bin 3. An outlet is provided at the bottom of the placement bin 3, and a length limiting mechanism and a diameter adjustment mechanism are provided inside the placement bin 3. A plurality of electric push rods four 25 are fixedly connected to the outer wall below the placement bin 3, and the telescopic ends of the plurality of electric push rods four 25 are fixedly connected to the same L-shaped baffle 6. The L-shaped baffle 6 is slidably connected to the bottom end of the outlet of the placement bin 3, and a slope 26 is provided at one end of the L-shaped baffle 6. A conveying mechanism is provided below the L-shaped baffle 6. When batch processing metal pipe fittings is required, first, the placement bin 3 is moved downward through the lifting mechanism to adjust its height. Then, the length limiting mechanism and the diameter adjustment mechanism in the placement bin 3 are adjusted to match the length and diameter of the metal pipe fittings to be processed. Then, a plurality of metal pipe fittings to be processed are placed in the placement bin 3. There is a slope in the placement bin 3, so that some metal pipe fittings will roll into the outlet, and then are blocked by the L-shaped baffle 6. And under the action of the diameter adjustment mechanism, the metal pipe fittings entering the outlet are arranged in a single column and discharged downward. Then, the placement bin 3 is raised to a suitable height again through the lifting mechanism. Finally, through the cooperation of the electric push rods four 25 and the conveying mechanism, the metal pipe fittings to be processed can be conveyed in sequence, without manual feeding, and is suitable for batch turning processing of metal pipe fittings of various lengths and diameters, greatly improving work efficiency.

[0033] As a further scheme in the present invention, the lifting mechanism includes an L-shaped bracket 2. The L-shaped bracket 2 is fixedly connected to the outer wall of the lathe body 1, and a hydraulic rod 4 is provided at the top of the L-shaped bracket 2. The telescopic end of the hydraulic rod 4 is fixedly connected to a fixed block 5, and the fixed block 5 is fixedly connected to the outer wall of the placement bin 3. The height of the placement bin 3 can be adjusted through the hydraulic rod 4.

[0034] As a further scheme in the present invention, the length limiting mechanism includes a length limiting plate 21. The shape of the length limiting plate 21 is adapted to the placement bin 3 and is slidably connected inside the placement bin 3, and the bottom end of the length limiting plate 21 extends into the outlet of the placement bin 3. Slide grooves two 24 are opened on the outer walls at both ends of the placement bin 3, and threaded rods 13 are provided outside the slide grooves two 24.

[0035] As a further scheme in the present invention, servo motors 15 are provided at one ends of the threaded rods 13, and threaded sliders 14 are threadedly slidably connected to the outer walls of the threaded rods 13. Both ends of the length limiting plate 21 pass through the slide grooves two 24 and are fixedly connected to the corresponding threaded sliders 14. By driving the threaded rods 13 connected thereto to rotate through the servo motors 15, the threaded sliders 14 can be made to drive the length limiting plate 21 to slide in the placement bin 3, so as to adjust the internal space in the placement bin 3, and the metal pipe fittings can be arranged in a column from top to bottom in the outlet of the placement bin 3, suitable for batch processing of metal pipe fittings of different diameters.

[0036] As a further solution in the present invention, the diameter adjustment mechanism includes a guide rod 18. Both ends of the guide rod 18 are fixedly connected with a first slider 17, and the two first sliders 17 are respectively slidably connected with the outer walls on both sides of the top of the placement bin 3. A second slider 19 is slidably connected to the outer wall of the guide rod 18, and the bottom end of the second slider 19 is slidably connected with the outer wall of the top of the length limiting plate 21. An electric push rod three 16 is fixedly connected to the outer wall of the top of the length limiting plate 21, and the telescopic end of the electric push rod three 16 is fixedly connected with the second slider 19. The position of the guide rod 18 can be adjusted by the electric push rod three 16.

[0037] As a further solution in the present invention, three third sliders 22 are arranged between the second slider 19 and one of the first sliders 17, and the three third sliders 22 are slidably connected to the outer wall of the guide rod 18. A first connecting spring 20 is fixedly connected between adjacent two third sliders 22, and the first connecting spring 20 is sleeved on the outer wall of the guide rod 18. A baffle 23 is fixedly connected to the outer walls of the three third sliders 22, and the bottom end of the baffle 23 extends into the discharge port of the placement bin 3. When the length limiting plate 21 moves, the second slider 19 on the length limiting plate 21 will contact the adjacent third slider 22 and apply a force to it, so as to adjust the distance between the third sliders 22. At the same time, because the bottom end of the baffle 23 on the third slider 22 extends into the discharge port of the placement bin 3, when the electric push rod three 16 adjusts the position of the guide rod 18, each baffle 23 will move synchronously in the discharge port, so as to separate the space in the discharge port, facilitating metal pipe fittings with different diameters to be arranged in a column from top to bottom in the discharge port.

[0038] As a further solution in the present invention, the conveying mechanism includes a U-shaped frame 7. On both outer walls of the top of the U-shaped frame 7, there are second electric push rods 11, and the second electric push rods 11 are fixedly connected to the bottom outer walls of the corresponding fixed blocks 5. A first sliding groove 9 is formed in the outer wall of the U-shaped frame 7, and two first electric push rods 10 are arranged inside the first sliding groove 9. One of the first electric push rods 10 is slidably connected to the inside of the first sliding groove 9, and the other first electric push rod 10 is fixedly connected to the inside of the first sliding groove 9. Arc-shaped carrier plates 12 are fixedly connected to the telescopic ends of the two first electric push rods 10, and a connecting plate 8 is fixedly connected between the first electric push rod 10 slidably connected to the inside of the first sliding groove 9 and the threaded slider 14 above it. When the above-mentioned threaded slider 14 moves, the first electric push rod 10 connected thereto can slide in the first sliding groove 9 through the connecting plate 8, and the arc-shaped carrier plate 12 on this first electric push rod 10 can be made to approach the other arc-shaped carrier plate 12, so as to adjust the distance between the two arc-shaped carrier plates 12, and metal pipe fittings of different lengths can be made to fall on the two arc-shaped carrier plates 12; and when it is necessary to convey the metal pipe fittings to the lathe body 1, the position height of the U-shaped frame 7 is adjusted by the second electric push rods 11, so that the distance from the top of the arc-shaped carrier plate 12 to the bottom of the L-shaped baffle 6 is between 1.1 times and 1.3 times the diameter of the metal pipe fitting. Thus, when the L-shaped baffle 6 is moved by the fourth electric push rod 25 to open the discharge port, the two ends of the metal pipe fitting at the bottommost position in the discharge port will respectively fall on the corresponding arc-shaped carrier plates 12, and a part of the metal pipe fitting in the discharge port will be exposed. Then, the fourth electric push rod 25 makes the L-shaped baffle 6 close the discharge port again. In this process, due to the action of the L-shaped baffle 6, the exposed part of the metal pipe fitting will return to the discharge port again, and then the metal pipe fitting on the arc-shaped carrier plate 12 can be conveyed to the lathe body 1 through the first electric push rod 10.

[0039] Working principle: When batch processing metal pipe fittings is required, first, the hydraulic rod 4 is used to move the placement bin 3 downward to adjust its height. Then, the servo motor 15 can drive the connected threaded rod 13 to rotate, enabling the threaded slider 14 to drive the length-limiting plate 21 to slide in the placement bin 3, thereby adjusting the internal space in the placement bin 3. This allows the metal pipe fittings to be turned and processed to be arranged in a column from top to bottom in the discharge port of the placement bin 3. Then, the electric push rod three 16 can adjust the position of the guide rod 18. When the length-limiting plate 21 moves, the slider two 19 on the length-limiting plate 21 will contact the adjacent slider three 22 and apply force to it, thereby adjusting the distance between the sliders three 22. At the same time, since the bottom end of the baffle 23 on the slider three 22 extends into the discharge port of the placement bin 3, when the electric push rod three 16 adjusts the position of the guide rod 18, the baffles 23 will move synchronously in the discharge port, thus separating the space in the discharge port. This facilitates the metal pipe fittings to be turned and processed to be arranged in a column from top to bottom in the discharge port. Then, multiple metal pipe fittings to be processed are placed in the placement bin 3. There is a slope in the placement bin 3, so some metal pipe fittings will roll into the discharge port and be blocked by the L-shaped baffle 6. And under the action of the baffle 23, the metal pipe fittings entering the discharge port are arranged in a single column and move downward. Then, the hydraulic rod 4 is used again to raise the placement bin 3 to an appropriate height. When the two threaded sliders 14 move synchronously, one of the threaded sliders 14 can make the connected electric push rod one 10 slide in the sliding groove one 9 through the connecting plate 8, enabling the arc-shaped carrier plate 12 on the electric push rod one 10 to approach the other arc-shaped carrier plate 12, thereby adjusting the distance between the two arc-shaped carrier plates 12 and allowing metal pipe fittings of different lengths to fall on the two arc-shaped carrier plates 12. When it is necessary to transport the metal pipe fittings to the lathe body 1, the position and height of the U-shaped frame 7 are adjusted by the electric push rod two 11 so that the distance from the top of the arc-shaped carrier plate 12 to the bottom of the L-shaped baffle 6 is between 1.1 times and 1.3 times the diameter of the metal pipe fitting. Thus, when the electric push rod four 25 moves the L-shaped baffle 6 to open the discharge port, the two ends of the metal pipe fitting at the bottom of the discharge port will respectively fall on the corresponding arc-shaped carrier plates 12, and part of the metal pipe fittings in the discharge port will be exposed. Then, the electric push rod four 25 makes the L-shaped baffle 6 close the discharge port again. During this process, due to the action of the L-shaped baffle 6, the exposed metal pipe fittings will return to the discharge port again. Then, the electric push rod one 10 can transport the metal pipe fittings on the arc-shaped carrier plate 12 to the lathe body 1, and the metal pipe fittings to be processed can be transported in sequence, eliminating the need for manual feeding. It is suitable for batch turning processing of metal pipe fittings of various lengths and diameters, greatly improving work efficiency.

[0040] Example 2, referring to Figures 6 - 8, a metal pipe fitting turning device. Compared with Embodiment 1, on the basis of Embodiment 1, mounting grooves 27 are formed on the outer walls of each baffle 23 facing away from the third electric push rod 16, and a plurality of rotating columns 33 are rotatably connected at equal distances inside the mounting grooves 27. Two slider fours 31 are symmetrically and slidably connected inside the mounting grooves 27, and a rack 32 is fixedly connected between the two slider fours 31. A gear 29 is fixedly connected to the outer wall of one side of each rotating column 33, and the gears 29 are all meshed with the rack 32. The inner wall of the top of the mounting groove 27 is fixedly connected with an electric push rod five 30, and the telescopic end of the electric push rod five 30 is fixedly connected with the slider four 31. After the position of the baffle 23 in the placement bin 3 is adjusted, the electric push rod five 30 in the mounting groove 27 is started. The electric push rod five 30 will push the connected slider four 31 to move downward, so that the rack 32 between the two slider fours 31 moves downward. Because the rack 32 is meshed with the gears 29 on each rotating column 33, when the rack 32 moves downward, each rotating column 33 can be rotated synchronously.

[0041] As a further scheme in the present invention, a swing plate 28 is fixedly connected to the outer wall of the other side of each rotating column 33, and a sliding cavity is formed inside the swing plate 28. An electromagnet 34 is arranged on one side inside the sliding cavity, and a magnetic plate 36 is slidably connected inside the sliding cavity. The magnetic force generated after the electromagnet 34 is energized is mutually exclusive with the magnetic plate 36, and a second connecting spring 35 is fixedly connected between the electromagnet 34 and the magnetic plate 36. A holding plate 37 is slidably connected to the other side of the sliding cavity. Once the holding plate 37 is fixedly connected to the magnetic plate 36, an anti-slip pattern is arranged at the other end of the holding plate 37, so that each swing plate 28 rotates, and each swing plate 28 is exposed from the mounting groove 27. Then, the electromagnet 34 in the sliding cavity of each swing plate 28 is energized. Because the magnetic force generated after the electromagnet 34 is energized is mutually exclusive with the magnetic plate 36, the magnetic plate 36 can stretch the second connecting spring 35 and move away from the electromagnet 34, so that the holding plate 37 extends out of the sliding cavity until the end of the holding plate 37 with the anti-slip pattern contacts the inner wall of the placement bin 3, thereby supporting the baffle 23. When a large number of metal pipe fittings are placed in the placement bin 3, the load borne by the baffle 23 can be shared through the swing plate 28 and the holding plate 37, the stability of the baffle 23 is improved, and the baffle 23 is prevented from deforming.

[0042] Working principle: After the position of the baffle 23 in the placement bin 3 is adjusted, the electric push rod five 30 in the installation groove 27 is activated. The electric push rod five 30 will push the slider four 31 connected to it downward, so that the rack 32 between the two sliders four 31 moves downward. Since the rack 32 meshes with the gears 29 on each rotating column 33, when the rack 32 moves downward, it can make each rotating column 33 rotate synchronously, so that each swing plate 28 rotates, and each swing plate 28 is exposed from the installation groove 27. Then, the electromagnet 34 in the sliding cavity of each swing plate 28 is energized. Since the magnetic force generated after the electromagnet 34 is energized repels the magnetic plate 36, it can make the magnetic plate 36 stretch the connecting spring two 35 and move away from the electromagnet 34, so that the top plate 37 extends out of the sliding cavity until the end of the top plate 37 with anti-slip lines contacts the inner wall of the placement bin 3, thereby supporting the baffle 23. When a large number of metal pipe fittings are placed in the placement bin 3, the load borne by the baffle 23 can be shared through the swing plate 28 and the top plate 37, improving the stability of the baffle 23 and preventing the baffle 23 from deforming.

[0043] Embodiment 3. Refer to Figure 9 , a metal pipe fitting turning device. Compared with Embodiment 2, on the basis of Embodiment 2, the outer walls of one side of the arc-shaped carrier plate 12 are fixedly connected with corner cylinders 41, and the telescopic ends of the corner cylinders 41 are fixedly connected with mounting plates 40. An arc-shaped pressing block 38 is arranged below the mounting plate 40, and a plurality of connecting springs three 39 are fixedly connected between the mounting plate 40 and the arc-shaped pressing block 38. When transporting the metal pipe fittings on the arc-shaped carrier plate 12, the corner cylinders 41 are activated, and the mounting plates 40 parallel to the metal pipe fittings can be rotated above the metal pipe fittings and moved downward, so that the arc-shaped pressing block 38 contacts the surface of the metal pipe fittings. Thus, under the action of a plurality of connecting springs three 39, the metal pipe fittings on the arc-shaped carrier plate 12 are fixed, which is convenient for fixing them on the lathe body subsequently.
