DETAILED DESCRIPTION

[0031] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The embodiment of the utility model provides a continuous processing mechanism for connecting pipes, such as Figures 1 to 9 As shown, the continuous processing mechanism is connected to an external lathe, including a frame 1, a material supply channel 2 installed on the frame 1, and a positioning component arranged at one side of the material supply channel 2 and slidably connected to the frame 1. The connecting pipe 4 is transferred to the positioning component through the material supply channel 2. The positioning component slides to the side of the frame 1 facing the lathe so that the tool on the lathe can perform inner hole processing and / or external thread processing on the connecting pipe 4. The frame 1 is also provided with a transfer mechanical claw 3 slidably connected to the frame 1. The transfer mechanical claw 3 clamps the connecting pipe 4 located at one end of the material supply channel 2 close to the positioning component and transfers it to the positioning component;

[0033] A material shifting block 5 is arranged at one end of the material supply channel 2 away from the positioning assembly, and a first electric guide rail 6 for sliding connection of the material shifting block 5 is arranged at the front side of the material supply channel 2 , and one side of the material shifting block 5 abuts against the connecting pipe 4 on the material supply channel 2 .

[0034] Specifically, in this embodiment, the material shifting block 5 has an initial position, in which the material shifting block 5 is located on the side of the material supply channel 2 away from the positioning assembly. The material shifting block 5 is used to assist in material loading. When a connecting tube 4 at one end of the material supply channel 2 close to the positioning assembly is grabbed by the transfer mechanical claw 3, the first electric guide rail 6 drives the material shifting block 5 to slide a preset distance from the initial position toward the other end of the material supply channel 2, so that each connecting tube 4 on the material supply channel 2 moves synchronously, and the next connecting tube 4 to be processed moves to the end of the material supply channel 2 close to the storage seat 7, so as to achieve the purpose of continuous material loading.

[0035] The transport mechanical claw 3 uses a two-arm mechanical clamp, and the two mechanical arms are driven by a motor to move closer to or away from each other to clamp the connecting tube 4.

[0036] In a preferred embodiment of the utility model, the positioning assembly includes a storage seat 7 and a pressure block 8. A second electric guide rail 9 for sliding connection to the storage seat 7 is provided on the frame 1. One end of the second electric guide rail 9 is connected to the feed channel 2. A third electric guide rail 10 parallel to the second electric guide rail 9 is provided above the storage seat 7 on the frame 1. The pressure block 8 is slidingly connected to the third electric guide rail 10 via a first driving assembly. The first driving assembly controls the pressure block 8 to approach or move away from the storage seat 7.

[0037] Specifically, in this embodiment, the second electric guide rail 9 is used to drive the storage seat 7 to reciprocate between the material supply channel 2 and the external lathe, and the pressing block 8 is driven by the third electric guide rail 10 to reciprocate between the material supply channel 2 and the external lathe.

[0038] The storage seat 7 and the pressing block 8 cooperate to press the connecting pipe 4 to achieve the positioning of the connecting pipe 4 and prevent the connecting pipe 4 from being offset during lathe processing.

[0039] In a preferred embodiment of the utility model, the first drive assembly includes a third guide block 11 slidably connected to the third electric guide rail 10, a first drive motor 12 installed on the third guide block 11, and a first lead screw 13 connected to the output end of the first drive motor 12. The first drive motor 12 is installed on the side of the third guide block 11 facing the storage seat 7, the first lead screw 13 is screwed to the pressure block 8, and a limit rod 14 is also provided between the second electric guide rail 9 and the third electric guide rail 10. The limit rod 14 is slidably connected to the frame 1 along the vertical direction, and the pressure block 8 is slidably connected to the limit rod 14 along the extension direction of the third electric guide rail 10.

[0040] Specifically, in this embodiment, when the first drive motor 12 drives the first screw 13 to rotate circumferentially, since the limit rod 14 is slidably connected to the frame 1 in the vertical direction, and the pressure block 8 is slidably connected to the limit rod 14, the pressure block 8 moves upward or downward along the first screw 13, thereby realizing the fixing operation and releasing operation of the connecting pipe 4.

[0041] In a preferred embodiment of the present invention, a groove 15 for horizontally placing the connecting pipe 4 is formed on one side of the storage seat 7 facing the pressing block 8 , and the groove wall of the groove 15 is in contact with the outer wall surface of the horizontally placed connecting pipe 4 .

[0042] Specifically, in this embodiment, when the connecting tube 4 is horizontally placed in the groove 15 of the storage seat 7, the surface of the connecting tube 4 is in contact with the groove wall. Since the surface of the connecting tube 4 is curved and has a recessed portion, the corresponding shape of the groove 15 is also irregular, so that the connecting tube 4 can be stably placed on the storage seat 7, and it is not easy for the connecting tube 4 to slide and deviate.

[0043] In a preferred embodiment of the utility model, a horizontal offset component and a vertical offset component are provided on the front side of the positioning component of the frame 1. The horizontal offset component drives the transfer mechanical claw 3 to move back and forth horizontally between the feed channel 2 and the storage seat 7. The vertical offset component drives the transfer mechanical claw 3 to slide in the vertical direction so that the connecting pipe 4 clamped by the transfer mechanical claw 3 moves from the top of the storage seat 7 into the storage seat 7.

[0044] Specifically, in this embodiment, since the groove 15 of the storage seat 7 needs to match the outer wall of the connecting tube 4, the height of the two ends of the storage seat 7 along the extension direction of the supply channel 2 is higher than the middle part of the storage seat 7. Therefore, when the transfer robot claw 3 transfers the connecting tube 4 from the supply channel 2 to the storage seat 7, the transfer robot claw 3 needs to be offset upward to prevent the connecting tube 4 from hitting the storage seat 7 and causing material falling or damage to the connecting tube 4.

[0045] In a preferred embodiment of the present invention, the horizontal offset assembly includes a fourth electric guide rail 16 parallel to the extension direction of the feed channel 2 and connected to the frame 1, and a fourth guide block 17 is slidably connected to the fourth electric guide rail 16, and the fourth guide block 17 is slidably connected to the transfer mechanical claw 3 in the vertical direction;

[0046] The vertical offset assembly includes an offset plate 18 fixed on the frame 1 and located below the fourth electric guide rail 16. The offset plate 18 has a raised portion on the side away from the ground to form a guide surface 19. The transfer mechanical claw 3 is provided with a follower rod 20, and one end of the follower rod 20 is against the guide surface 19. When the transfer mechanical claw 3 translates along the fourth electric guide rail 16, the follower rod 20 moves to the raised portion of the offset plate 18 to cause the transfer mechanical claw 3 to be vertically offset upward to make way for the edge of the storage seat 7.

[0047] Specifically, in this embodiment, the fourth electric guide rail 16 drives the fourth guide block 17 to slide in the horizontal direction. When the transfer robot claw 3 is offset in the vertical direction under the drive of the offset plate 18, the fourth guide block 17 remains stationary in the vertical direction, and the transfer robot claw 3 is offset in the vertical direction compared to the fourth guide block 17 to achieve compensation.

[0048] When the follower rod 20 moves from the low point to the high point of the guide surface 19 , the deflection plate 18 remains stationary, the follower rod 20 deflects upward, and the transfer robot claw 3 deflects upward together with the follower rod 20 .

[0049] The offset plate 18 is provided with a horizontal anti-slip groove 21, in which an anti-slip rod 22 is inserted, and a main slide bar 23 is fixed at one end of the anti-slip rod 22. The main slide bar 23 is vertically arranged on the side of the transport mechanical claw 3 away from the storage seat 7, and a secondary slide bar 24 is slidably inserted at one end of the main slide bar 23 away from the offset plate 18, and the other end of the secondary slide bar 24 is fixed to the side of the fourth guide block 17 facing the ground. During the movement of the transport mechanical claw 3, the anti-slip rod 22 slides in the anti-slip groove 21 in the horizontal direction, and the secondary slide bar 24 performs height compensation according to the offset amount of the transport mechanical claw 3 in the vertical direction, so as to avoid the situation where the follower rod 20 accidentally detaches from the offset plate 18 after the continuous processing mechanism has been running for a period of time, thereby improving the durability and reliability of the continuous processing mechanism.

[0050] In a preferred embodiment of the utility model, the horizontal offset assembly also includes a positioning plate 25 and a mounting plate 26. The frame 1 is provided with a slide groove 27 extending along the width direction on both sides of the positioning plate 25. The positioning plate 25 is slidably connected in the slide groove 27 along the width direction of the frame 1. The two ends of the fourth electric guide rail 16 are fixed to the positioning plate 25. The mounting plate 26 is fixed on the frame 1 and is located on the side of the positioning plate 25 away from the storage seat 7. A second drive motor 28 is arranged on the mounting plate 26. A second lead screw 29 is fixed to the output end of the second drive motor 28. The second lead screw 29 is screwed to the positioning plate 25. The second drive motor 28 controls the positioning plate 25 to slide along the slide groove 27 to approach or move away from the storage seat 7.

[0051] Specifically, in this embodiment, the second driving motor 28 is slidably connected to the mounting plate 26 along the extending direction of the fourth electric guide rail 16 .

[0052] The fourth guide block 17 is clamped to the transfer robot claw 3 in the width direction of the frame 1 , that is, when the fourth guide block 17 approaches or moves away from the storage seat 7 , the transfer robot claw 3 moves following the fourth guide block 17 .

[0053] When the transfer robot claw 3 places the connecting tube 4 on the storage seat 7, and the pressure block 8 cooperates with the storage seat 7 to complete the fixation of the connecting tube 4, the second drive motor 28 controls the second lead screw 29 to rotate circumferentially, so that the positioning plate 25 moves from the end of the second lead screw 29 close to the storage seat 7 to the end of the second lead screw 29 away from the storage seat 7, and the fourth electric guide rail 16 on the positioning plate 25 follows the movement, and the fourth guide block 17 drives the transfer robot claw 3 to move away from the storage seat 7 to leave space for the connecting tube 4 to continue to move. At this time, the follower rod 20 briefly leaves the guide surface 19 of the offset plate 18, and the anti-slip rod 22 slides along the width direction of the offset plate 18 to compensate.

[0054] After the positioning assembly moves the connecting pipe 4 to the external lathe, the transfer mechanical claw 3 moves to the end of the feed channel 2 close to the storage seat 7 under the action of the horizontal offset assembly, and the second drive motor 28 controls the transfer mechanical claw 3 to approach the storage seat 7 through the second lead screw 29, so that the end of the follower rod 20 away from the transfer mechanical claw 3 returns to the guide surface 19 of the offset plate 18.

[0055] In a preferred embodiment of the present invention, the material supply channel 2 has a loading surface 30 which is tilted to form an inclined slot. When the connecting pipe 4 is placed in the inclined slot, one end of the connecting pipe 4 away from the loading surface 30 is offset in a direction away from the ground.

[0056] Specifically, in this embodiment, the connecting pipe 4 has a coaxial first pipe opening and a second pipe opening, and the connecting pipe 4 also has a third pipe opening that is perpendicular to the pipeline formed by the two pipe openings. When the connecting pipe 4 is placed in the inclined groove, the center of gravity follows the inclination of the inclined groove, so that the third pipe opening is tilted upward, reducing the probability of the connecting pipe 4 falling from the supply channel 2, and making the posture of the connecting pipe 4 more stable when the supply channel 2 slides.

[0057] In a preferred embodiment of the present invention, a side of the material shifting block 5 facing the positioning assembly is provided with a clearance surface 31 .

[0058] Specifically, in this embodiment, when the material shifting block 5 shifts the connecting tube 4, the positioning surface 31 is in contact with the outer wall of the connecting tube 4, so that the connecting tube 4 is evenly stressed when the material shifting block 5 shifts the material, and the movement is more stable.

[0059] In summary, the connecting tubes 4 are arranged one by one on the feeding channel 2, the horizontal offset assembly drives the transfer manipulator to move to the end of the feeding channel 2 close to the storage seat 7 to grab a connecting tube 4, the material shifting block 5 slides along the end of the first electric guide rail 6 away from the storage seat 7 toward the direction close to the storage seat 7, and shifts each connecting tube 4 on the feeding channel 2 toward the direction close to the storage seat 7, so that the next connecting tube 4 to be processed moves to the end of the feeding channel 2 close to the storage seat 7;

[0060] Then, the horizontal offset component drives the transfer robot to move toward the storage seat 7. Under the action of the vertical offset component, the transfer robot shifts upward, so that the connecting tube 4 gives way to the edge of the storage seat 7 close to the material supply channel 2. Then, the transfer robot moves to the front side of the storage seat 7. Under the action of the vertical offset component, the transfer robot descends to place the connecting tube 4 horizontally on the storage seat 7. The first drive component controls the pressing block 8 to press down to the upper surface of the connecting tube 4 to fix the connecting tube 4. Then, the storage seat 7 and the pressing block 8 are synchronously translated to move the connecting tube 4 to the processing position of the external lathe. After the processing of the connecting tube 4 is completed, the first drive component drives the pressing block 8 to move upward, and the connecting tube 4 can be removed from the storage seat 7.

[0061] The storage seat 7 and the pressing block 8 are reset under the action of the first driving assembly, and the transfer robot grabs the next connecting tube 4 to achieve the effect of continuous processing of the connecting tube 4. There is no need to manually clamp the connecting tube 4 one by one, thereby improving the feeding efficiency and processing efficiency of the connecting tube 4.
