Description

Technical Field

[0001] This application relates to the field of workpiece transportation and processing technology, and in particular to an automatic transportation and bending device. Background Technology

[0002] Automobile production involves the assembly of numerous components, among which brake lines are extremely important in the braking system. Furthermore, specialized connectors are required to connect the brake lines.

[0003] Reference Figure 1 As shown, a connector for connecting automotive brake lines includes a first end 11, a first ring block 12, and a first straight bar 13 disposed on the side of the first ring block 12. A thin tube 14 is disposed within the first end 11, and the thin tube 14 is directly connected to the first ring block 12 and has a first outlet on the first ring block 12; the thin tube 14 is used for supplying brake fluid, and the first straight bar 13 is bent into a small hook. The workpiece referred to below is... Figure 1 The connector in the middle.

[0004] In existing technology, a bending machine is used to bend the first straight section 13 of the workpiece. However, after bending the workpiece, the thin tube 14 inside the first end 11 needs to be inspected to check for blockages. Since a workpiece with a blocked thin tube 14 is considered defective and will affect its normal use in the automobile, it is necessary to inspect the bent workpiece to check if the thin tube 14 is unobstructed. The inspection of the thin tube 14 is done manually. A worker inserts a testing guide that fits the thin tube 14. If a clear foreign object is felt during insertion and the end of the guide cannot pass through the first outlet, it indicates a blockage inside the thin tube 14, and the worker removes the defective workpiece. The entire inspection process is done manually, which is time-consuming and labor-intensive, and prone to worker misjudgment.

[0005] Therefore, the applicant provides a production equipment that automatically performs continuity testing on workpieces and then bends qualified workpieces. Summary of the Invention

Detailed Implementation

[0054] The following is in conjunction with the appendix Figure 1-11This application will be described in further detail.

[0055] This application discloses an automatic transport and bending device. Example 1:

[0056] Reference Figure 2 As shown, an automatic transport and bending device includes a base 2, a conveying device 3, a guiding device 4, a bending device 5, a first clamping and transferring assembly 6, and a second clamping and transferring assembly 7. The conveying device 3 is arranged on the base 2 for transporting workpiece 1. The guiding device 4 is arranged on one side of the output end of the conveying device 3, and the bending device 5 is arranged on one side of the guiding device 4. The first clamping and transferring assembly 6, arranged on the base 2, clamps and transfers the workpiece 1 from the output end of the conveying device 3 to the guiding device 4. The second clamping and transferring assembly 7, arranged on the base 2, clamps the workpiece 1 from the guiding device 4 to the bending device 5. This achieves the automatic transport, guiding, and bending processing of workpiece 1. The various devices and components cooperate to form a continuous processing production line. The workpieces on the production line are first guided, and then the inspected workpieces are bent, reducing manual intervention and operational errors, and improving the final workpiece qualification rate and production efficiency.

[0057] Reference Figure 3As shown, the conveying device 3 includes a conveying body 31, a conveying track 32, a first placement seat 33, and a first drive motor 34. The conveying body 31 is arranged on the base 2, providing a support structure for the entire conveying process. The conveying body 31 is made of metal material to ensure its strength and stability. The conveying track 32 is arranged inside the conveying body 31, and the conveying track 32 is also provided with a first placement seat 33 for placing the workpiece 1. The first placement seat 33 includes a fixed base plate 331 fixedly arranged on the conveying track 32, a first positioning column head 332 arranged on the fixed base plate 331 for positioning the workpiece 1, and a placement plate 333 arranged on the fixed base plate 331 for placing the workpiece 1. The fixed base plate 331 can be fixed to the conveying track 32 by welding or bolting to ensure that it will not loosen during the conveying process. The first positioning column head 332 can be a cylindrical column, and its top end is also provided with a first positioning head 334 that engages with the first ring block 12, which can accurately position the workpiece 1. The placement plate 333 has first limiting plates 335 arranged at an angle on both sides to limit the position of the first end 11, restricting the position of the workpiece 1 on the placement plate 333 and preventing the workpiece 1 from shaking and falling during transportation. The first drive motor 34 drives the conveyor belt 32 to move. The motor is connected to the conveyor belt 32 through a transmission method such as a belt or chain, thereby driving the conveyor belt 32 to rotate cyclically and realize the conveying of the workpiece 1. The first drive motor 34 provides power to drive the conveyor belt 32 to move within the conveying body 31. The workpiece 1 placed on the first placement seat 33 moves forward together with the conveyor belt 32; and each workpiece 1 is placed individually in each first placement seat 33, avoiding contact and interference between the workpieces 1. This combination method enables the workpiece 1 to be transported to the designated position in an orderly and stable manner, improving the conveying efficiency and accuracy.

[0058] Reference Figure 4 and Figure 5As shown, the connecting device 4 includes a connecting frame 41, a connecting platform 42, a first connecting assembly 43, and a first hydraulic cylinder. The connecting frame 41 includes a first upright plate 411 arranged on the base 2 and a first sliding rod 412 arranged on the first upright plate 411 for sliding of the first connecting assembly 43. The first upright plate 411 is a metal plate, fixed to the base 2 by bolts, providing support for the entire connecting device 4. The first sliding rod 412 is a cylindrical metal rod, horizontally arranged on the first upright plate 411, providing a track for the movement of the first connecting assembly 43. The connecting platform 42 has a first fixed base 421 arranged in the connecting frame 41, a first base block 422 arranged on the first fixed base 421, a first positioning block 423 arranged on the first base block 422 for engaging with the first ring block 12, and a first placement block 424 arranged on the first sliding rod 412 for placing the first end 11. The first fixed base 421 is fixed inside the conduction frame 41 by welding, providing stable support for the conduction platform 42. The first base block 422 is a metal block fixedly installed on the first fixed base 421. A first protrusion 4231 is provided on the end of the first positioning block 423, and a first arc-shaped block 4232 is provided on the first protrusion 4231. Several first positioning blocks 423 are provided and are arranged in a ring. The arc-shaped surface of the first arc-shaped block 4232 fits against the inner side of the first ring block 12, so that the workpiece 1 can be positioned more accurately. In this embodiment, there is a gap between the first arc-shaped blocks 4232. The diameter of the first protrusion 4231 is larger than the diameter of the first arc-shaped block 4232. The diameter of the first arc-shaped block 4232 is the same as the diameter of the inner hole of the first ring block 12 of the workpiece 1. This allows the first ring block 12 to be snapped onto the first arc-shaped block 4232. At the same time, the first protrusion 4231 provides support and limitation for the plane of the first ring block 12. This creates a gap between the workpiece 1 and the first positioning block 423, facilitating subsequent clamping by the first clamping and transfer assembly 6. The first placement block 424 has a groove-shaped structure to facilitate the placement of the first end 11.

[0059] Reference Figure 6As shown, the first conductive assembly 43 has a first engaging member 431 slidably arranged on the first sliding rod 412 and used to engage the first end 11, and a first punch 432 slidably arranged on the first sliding rod 412 and inserted into the thin tube 14. The first engaging member 431 has a first movable block 4311 arranged on the first sliding rod 412. The first movable block 4311 can be a square slider, which can slide freely on the first sliding rod 412 through the cooperation of the slider with the first sliding rod 412. The first movable block 4311 is equipped with a first engaging post 4312, and a first hole 4313 is arranged in the first engaging post 4312. The first engaging post 4312 is adapted to engage with the first end 11. The first movable block 4311 is also equipped with a first limiting post 4314, which is vertically arranged on the bottom side of the first engaging post 4312. The first punch 432 has a second movable block 4321 arranged on the first sliding rod 412. A third movable block 4322 is arranged on the side of the second movable block 4321 away from the first movable block 4311. A first crossbar 4323 is arranged on the second movable block 4321 and is connected to the third movable block 4322. A punch 4324 is mounted on the first crossbar 4323 and is parallel to the plane of the base 2. The third movable block 4322 is also provided with a first guide rod 43221, and a second limiting post 43222 is arranged at the end of the first guide rod 43221. The first vertical plate 411 is equipped with a first limiting plug-in post 4111, and a second limiting plug-in post 4112 is vertically arranged below the first limiting plug-in post 4111. The first limiting plug-in post 4111 is plugged into and limited by the first limiting post 4314, and the second limiting plug-in post 4112 is plugged into and limited by the second limiting post 43222. A waste collection box is arranged on the side of the conduction device 4 to collect waste workpieces 1 generated during the conduction process. The first hydraulic cylinder drives the first conductive assembly 43 to slide. An oil pipe extends from the first hydraulic cylinder and connects to the first movable block 4311 and the second movable block 4321. The movement stroke and speed of the two movable blocks are synchronously controlled through the hydraulic circuit to ensure that the punch 4324 maintains coaxiality stability and positioning accuracy during the conductive operation. The first hydraulic cylinder drives the mutual movement of the first movable block 4311 and the second movable block 4321 through the control of the two hydraulic circuits, locking and limiting the first end 11 of the workpiece 1 to maintain the overall stability of the workpiece 1. The movement of the second movable block 4321 allows the punch 4324 to pass through the first locking post 4312 of the first movable block 4311. The punch 4324 enters the thin tube 14 of the workpiece 1 and conducts electricity through the thin tube 14. The first hydraulic cylinder is not shown in the figure.

[0060] Workpiece 1 is placed on the guide platform 42 by the first clamping and transferring assembly 6, and positioned by the first positioning block 423 and the first placement block 424. The first hydraulic cylinder drives the first movable block 4311 to move on the first sliding rod 412. The first snap-fit ​​post 4312 on the first movable block 4311 snaps into the first end 11 of the workpiece 1 to limit the workpiece 1; and the first limiting post 4314 on the first movable block 4311 and the first limiting insertion post 4111 on the first upright plate 411 are mutually inserted to limit the workpiece. The second movable block 4321 moves towards the first movable block 4311 on the first sliding rod 412. The punch 4324 on the second movable block 4321 moves towards the first locking post 4312 of the first movable block 4311. The first locking post 4312, the punch 4324, and the thin tube 14 of the workpiece 1 are arranged coaxially. Because the punch 4324 can pass through the first locking post 4312 and enter the thin tube 14 of the workpiece 1, the punch 4324 moves and penetrates the thin tube 14. The third movable block 4322 and the second movable block 4321 are provided with the first crossbar 4323. Therefore, the third movable block 4322 moves synchronously with the second movable block 4321. The second limiting post 43222 on the third movable block 4322 is inserted and limited by the second limiting insertion post 4112 on the first upright plate 411, thereby limiting the range of motion of the second movable block 4321. When the second movable block 4321 moves to the second limit insertion post 4112, it means that the punch 4324 has moved to the designated position. At this time, the punch 4324 extends from the first outlet of the first ring block 12 and is located in the gap between the first arc blocks 4232. To detect the continuity of the workpiece 1, an infrared sensor is arranged on the first clamping and transfer assembly 6. The infrared light is directed towards the first arc block 4232. When the punch 4324 is located in the gap between the first arc blocks 4232, it sends a signal to the control center. After processing, the control center determines that the workpiece 1 is qualified and feeds back the signal. The second movable block 4321 and the first movable block 4311 are retracted through the oil circuit control of the first hydraulic cylinder. The second clamping and transfer assembly 7 clamps and transports the qualified workpiece 1 to the bending device 5. When there is a blockage inside the thin tube 14, the punch 4324 cannot penetrate completely. The punch 4324 cannot pass through the first outlet of the workpiece 1 into the gap between the first arc-shaped blocks 4232. The infrared sensor cannot detect the signal from the punch 4324 inside the first arc-shaped blocks 4232. The control center receives a signal indicating that there is a blockage inside the workpiece 1, making it a defective workpiece 1. The second clamping and transferring assembly 7 clamps the defective workpiece 1 on the guiding platform 42 and places it into the waste collection box, instead of transferring it to the bending device 5, facilitating subsequent recycling. This combination method enables precise connection of the through hole in the workpiece 1, improving the efficiency and quality of the connection.

[0061] Reference Figure 7 and Figure 8As shown, the bending device 5 includes a bending frame 51, a bending platform 52, a pressing and abutting mechanism 53, and a bending assembly 54. The bending frame 51 is arranged on the base 2, providing a support structure for the entire bending device 5. The bending platform 52 includes a first fixed seat 521 arranged on the bending frame 51 and engaged with the first straight bar 13, and a first push rod assembly 522 arranged on the first fixed seat 521 and moving up and down to engage and limit the first ring block 12. The first fixed seat 521 is provided with a first fixed slot to engage and limit the first straight bar 13, and the first fixed seat 521 is provided with a first opening 523 for the first push rod assembly 522 to move. The first push rod assembly 522 has a first lifting rod 5221 vertically arranged in the first fixed seat 521 and a lifting rod driving component 5222 for driving the first lifting rod 5221 to move. The top end of the first lifting rod 5221 is a tapered tip to facilitate engagement with the first ring block 12.

[0062] The lifting rod drive component 5222 has a movable base 52221 arranged within the bending frame 51. A rotating seat 52222 is arranged within the movable base 52221, and a rotating sleeve 52223 is mounted on the rotating seat 52222. The rotating sleeve 52223 is threadedly connected to the rotating seat 52222. The end of the first lifting rod 5221 is snapped into the rotating sleeve 52223. A driven gear 52224 is arranged on the movable base 52221 and is connected to the rotating sleeve 52223, driving the rotating sleeve 52223 to rotate. A driving gear 52225 is meshed with the driven gear 52224 on its side. A gear motor 52226 is arranged within the movable base 52221 to drive the driving gear 52225 to rotate, which in turn drives the driven gear 52224 to rotate. The gear motor 52226 drives the drive gear 52225 to rotate, which in turn drives the driven gear 52224 to rotate. The driven gear 52224 then drives the rotating sleeve 52223 to rotate. Since the rotating sleeve 52223 is threadedly connected to the rotating seat 52222, the rotation of the rotating sleeve 52223 will cause the first lifting rod 5221 to move up and down, thereby locking and limiting the first ring block 12.

[0063] Reference Figure 7 and Figure 8 As shown, the pressing and abutting mechanism 53 has a first pressing housing 531 arranged on the bending frame 51. A first pressing head 532 is arranged at the output end of the first pressing housing 531. The first pressing head 532 is arranged perpendicular to the first lifting rod 5221. A first lifting motor 533 is provided on the top of the first pressing housing 531 to drive the first pressing head 532 to rise and fall. A second lifting rod is arranged on the output end of the first lifting motor 533 and fixedly connected to the first pressing head 532. The first lifting motor 533 drives the first pressing head 532 to rise and fall through the second lifting rod, pressing the workpiece 1 against the bending platform 52.

[0064] The bending assembly 54 has a first guide rail 541 arranged on the bending frame 51. A first sliding plate 542 is slidably arranged on the first guide rail 541. A first fixing block 543 is arranged on the first sliding plate 542. A bending head 544 is arranged at the end of the first fixing block 543. The bending head 544 is vertically arranged on the first fixing seat 521. The contact surface between the bending head 544 and the first straight bar 13 is an arc-shaped surface. A second lifting motor 545 is arranged on the bending frame 51 to drive the first sliding plate 542 to slide. The second lifting motor 545 drives the first sliding plate 542 to slide on the first guide rail 541, and the bending head 544 moves accordingly to perform a bending operation on the workpiece 1 that is pressed down. Alternatively, a screw and nut drive can be used instead of the second lifting motor 545 to drive the first sliding plate 542 to slide.

[0065] Workpiece 1 is clamped by the second clamping and transferring assembly 7 from the guiding device 4 and transported to the bending platform 52 of the bending device 5 after passing the guiding test. Workpiece 1 is placed at the first opening 523 of the first fixed seat 521, and at this time the first lifting rod 5221 is in the retracted state, that is, the tapered tip at the top has not been pushed out of the first opening 523. When the first ring block 12 is placed on the first opening 523, the gear motor 52226 arranged in the bending frame 51 drives the driving gear 52225 to rotate and drives the driven gear 52224 to rotate. The rotation of the driven gear 52224 drives the rotating sleeve 52223 connected to it to rotate. The rotating sleeve 52223 rotates in the internal thread of the rotating seat 52222 in the movable base 52221 to realize the lifting and lowering of the rotating sleeve 52223, and finally realizes that the first lifting rod 5221 on the rotating sleeve 52223 extends out at the first opening 523. Meanwhile, a vision inspection device is installed on the bending frame 51 to detect the placement of workpiece 1 at the first opening 523 and transmit the signal to the control center. The control center provides feedback and sends an output signal to the pressing and abutting mechanism 53. The first lifting motor 533 drives the first pressing head 532 to move vertically downward. The outer ring of the first pressing head 532 abuts against the first ring block 12. The first ring block 12, the first fixed seat 521, and the first pressing head 532 abut against each other to maintain stability, and the first straight strip 13 of workpiece 1 extends out of the first fixed seat 521. The second lifting motor 545 on the bending frame 51 drives the first sliding plate 542 to move towards the first straight strip 13. The bending head 544 contacts and squeezes the first straight strip 13, bending it. After bending, the bending assembly 54 retracts, and the pressing and abutting mechanism 53 rises and no longer abuts against workpiece 1. The gear motor 52226 drives the drive gear 52225 to reverse, thereby lowering the first lifting rod 5221. The second clamping and transfer assembly 7 clamps the bent workpiece 1 and moves it onto the discharge rack 22.

[0066] Reference Figure 9As shown, the first clamping and transferring assembly 6 includes a first support rod 61, a first track 62, a first sliding plate 63, a first clamping component 64, and a first cylinder 65. The first support rod 61 is arranged on the machine base 2, providing support for the entire first clamping and transferring assembly 6. The first support rod 61 is a metal rod, fixed to the machine base 2 by bolts. The first track 62 is arranged vertically on the first support rod 61, and the first sliding plate 63 is slidably arranged on the first track 62. The first track 62 is a linear guide rail, ensuring the linear movement of the first sliding plate 63. The first clamping component 64 includes a second guide rail 641 arranged on the first sliding plate 63, a first moving block 642 slidably arranged on the second guide rail 641, a first gripper 643 arranged on the first moving block 642 for clamping the workpiece 1, and a second cylinder 644 for driving the first moving block 642 to rise and fall. The first moving block 642 is also equipped with a first movable motor 645 for driving the first gripper 643. The first cylinder 65 drives the first sliding plate 63 to slide on the first track 62, the second cylinder 644 drives the first moving block 642 to rise and fall on the second guide rail 641, and the first movable motor 645 drives the first gripper 643 to open and close, thereby realizing the clamping and transfer of workpiece 1.

[0067] The first cylinder 65 drives the first sliding plate 63 to move on the first track 62 to the output end of the conveying device 3. The second cylinder 644 drives the first moving block 642 to descend. The first movable motor 645 drives the first gripper 643 to clamp the workpiece 1. Then, the second cylinder 644 drives the first moving block 642 to rise. The first cylinder 65 then drives the first sliding plate 63 to move above the connecting device 4, placing the workpiece 1 on the connecting device 4. At the same time, an infrared sensor for detecting the workpiece 1 in the conveying device 3 is arranged on the first support rod 61 of the first clamping and transferring assembly 6. The infrared sensor positions the first straight bar 13 of the workpiece 1 placed on the first positioning column 332 and sends a signal to the control center to determine whether there is a workpiece 1 on the first positioning column 332, thereby allowing the first gripper 643 to clamp the workpiece 1 more efficiently. It can accurately and quickly transfer the workpiece 1 from the conveying device 3 to the connecting device 4.

[0068] Reference Figure 10 and Figure 11As shown, the second clamping and transferring assembly 7 includes a second track 71, a second sliding component 72, and a second drive motor 73. The second track 71 is arranged on the base 2, and the second sliding component 72 is arranged on the second track 71. The second track 71 is a linear guide rail, providing a track for the movement of the second sliding component 72. The second sliding component 72 includes a second sliding plate 721 arranged on the second track 71, a third guide rail 722 arranged on the second sliding plate 721, a first lifting plate 723 slidably arranged on the third guide rail 722, and a third cylinder 724 for driving the first lifting plate 723 to rise and fall. The first lifting plate 723 has a second gripper component 7231 and a third gripper component 7232 installed on both sides. The second gripper component 7231 has a first lifting plate 72311 arranged on the first lifting plate 723, a second gripper 72312 arranged on the bottom side of the first lifting plate 72311, and a first lifting cylinder 72313 for driving the first lifting plate 72311 to move. The third gripper component 7232 includes a second lifting plate 72321 arranged on the first lifting plate 723, a third gripper 72322 arranged on the bottom side of the second lifting plate 72321, and a second lifting cylinder 72323 that drives the second lifting plate 72321 to move. A second drive motor 73 drives a second sliding component 72 to move on the second track 71, a third cylinder 724 drives the first lifting plate 723 to rise and fall on the third guide rail 722, and a first lifting cylinder 72313 drives the second gripper 72312 and the third gripper 72322 to open and close, thereby achieving the clamping and transfer of the workpiece 1. The distance between the second gripper component 7231 and the third gripper component 7232 is the same as the distance between the guiding platform 42 and the bending platform 52, and the guiding platform 42 and the bending platform 52 are located on the same axis.

[0069] The second drive motor 73 moves the second sliding component 72 above the conduction device 4. At this time, the second gripper component 7231 is directly above the conduction platform 42, and the third gripper component 7232 is directly above the bending platform 52. The first lifting cylinder 72313 drives the first lifting plate 72311 to extend the second gripper 72312. Similarly, the second lifting cylinder 72323 drives the second lifting plate 72321 to extend the third gripper 72322. The third cylinder 724 drives the first lifting plate 723 to move downward, allowing the second gripper 72312 and the third gripper 72322 to descend to the position of workpiece 1. The second gripper 72312 and the third gripper 72322 simultaneously clamp the workpiece 1 on the conduction platform 42 and the workpiece 1 on the bending platform 52. The third cylinder 724 drives the first lifting plate 723 to rise, and the second drive motor 73 drives the second sliding component 72 to slide. After sliding, workpiece 1 on the second gripper 72312 is positioned above the bending platform 52, and workpiece 1 on the third gripper 72322 is positioned on the discharge rack 22; the third cylinder 724 drives the first lifting plate 723 to descend. Simultaneously, the second gripper 72312 and the third gripper 72322 are released, with workpiece 1 on the second gripper 72312 placed on the bending platform 52 and workpiece 1 on the third gripper 72322 falling onto the discharge rack 22. Simultaneously, the second gripper component 7231 and the third gripper component 7232 of the second clamping and transfer assembly 7 synchronously realize the functions of clamping for loading and clamping for unloading, improving work efficiency.

[0070] The implementation principle of the automatic transport and bending equipment in this application embodiment is as follows: This automatic transport and bending equipment transports workpiece 1 to a designated position through a conveying device 3. A first clamping and transferring component 6 transfers workpiece 1 from the conveying device 3 to a guiding device 4 for guiding processing. Then, a second clamping and transferring component 7 transfers the guided workpiece 1 to a bending device 5 for bending processing. Simultaneously, the second clamping and transferring component 7 transfers the bent workpiece 1 to a discharge rack 22. The various devices and components cooperate to form a complete automated processing system, reducing manual operation and improving production efficiency and product quality stability. A display screen 21 is also installed on this device to show the working status, thereby allowing for adjustments to the production status of workpiece 1. Compared with traditional processing methods, this equipment better adapts to the needs of large-scale production. Furthermore, this device first performs a guiding operation on workpiece 1 to check its qualification, and then transfers the qualified workpiece 1 through the second clamping and transferring component 7 to the bending device 5 for bending, producing a qualified workpiece 1. At the same time, the unbent workpiece 1 is easier to position when placed on the guiding device 4. Compared with existing technologies, this device inspects before bending, reducing the impact of defective workpieces on overall production. It ensures that workpiece 1 fed into bending device 5 is qualified and can be directly produced as qualified workpiece 1. Furthermore, the automated mechanical device 4 improves the inspection speed compared to manual methods. It can also be adjusted and optimized according to different workpiece 1 specifications and processing requirements. Example 2:

[0071] The difference between this embodiment and the above embodiment is that a correction component can also be arranged on the upper end of the first moving block 642 of the first clamping and transferring assembly 6. The correction component includes a first electric telescopic rod arranged on the end of the first moving block 642 and a first abutment joint arranged on the output end of the first electric telescopic rod. The first abutment joint is vertically arranged within the first placement seat 33 and coaxially arranged with the first positioning column 332. The first abutment joint is structurally corresponding to the first positioning column 332. The correction component can be configured according to actual conditions; it is not shown in the figure.

[0072] The implementation principle of this application embodiment is as follows: When the workpiece 1 is placed on the conveying device 3, the first ring block 12 of the workpiece 1 needs to be aligned with the first positioning column 332 on the first placement seat 33 by manual feeding. However, in this process, the first ring block 12 of the workpiece 1 may not be in complete contact with the end face of the first positioning column 332. That is, the end face of the first ring block 12 on the first positioning column 332 may not be parallel to the first positioning column 332, that is, the first ring block 12 is tilted and offset. This makes it difficult to effectively place workpiece 1 on the subsequent guiding platform 42 and bending platform 52 during the subsequent clamping and rotation process. Since the first arc-shaped block 4232 and the first lifting rod 5221 are both made of metal, placing the tilted workpiece 1 into the machine will damage the inner ring surface of the first ring block 12. Therefore, before transferring workpiece 1, it is necessary to ensure that workpiece 1 is fully in contact with the end face of the first positioning pin 332, guaranteeing that it is parallel to the first positioning pin 332. This ensures that workpiece 1 and the entire machine base 2 are parallel during clamping and transfer, allowing for rapid positioning of workpiece 1 in subsequent operations without damaging its surface.

[0073] When the first moving block 642 moves to directly above the workpiece 1, because the first end 11 of the workpiece 1 is arranged coaxially with the first ring block 12, the first electric telescopic rod moves vertically downward and presses down against the upper end face of the first ring block 12 on the first positioning column 332, making the first ring block 12 completely contact the end face of the first positioning column 332. Then the first electric telescopic rod rises, and at the same time the first moving block 642 slides down and drives the first gripper 643 to clamp the first end 11 of the workpiece 1.

[0074] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
