Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to an automatic track assembly system. Background Technology

[0002] Tracked vehicles are one of the most common drive systems in the construction machinery industry, offering numerous advantages such as high stability, strong load-bearing capacity, high adaptability, and strong impact resistance. Tracked equipment can be used in various fields including industry, agriculture, and forestry, and is particularly effective in moist and soft soil conditions. In recent years, with the advancement of industrial intelligence, the demand for tracked equipment has continued to grow.

[0003] Currently, there is no automated assembly of track components in the industry. Traditional track assembly methods involve manually lifting and placing the tracks. This poses a safety hazard as the tracks, which are heavy, need to be lifted during the laying process. Furthermore, there is usually no positioning for the tracks and the excavator underframe assembly. Multiple adjustments are required during the assembly process, resulting in a long cycle time and low production efficiency. In addition, manual assembly methods require a large number of personnel, are labor-intensive, have low production efficiency, and pose significant safety hazards. Summary of the Invention

[0004] The main objective of this invention is to provide an automated track assembly system, which aims to solve existing technical problems.

[0005] To achieve the above objectives, the present invention provides an automated track assembly system, comprising: The conveyor line is equipped with AGV trolleys for transporting track beam assemblies; Track placement slot, used to hold tracks; A stretching and wrapping mechanism is provided on a guide mechanism, which is parallel to the side of the conveyor line. The stretching and wrapping mechanism grabs the first end of the track and moves along the first direction on the guide mechanism to stretch the track to a fully unfolded state. A push-fit mechanism, connected to the guide mechanism and arranged along the second direction, is used to push the deployed track to the track beam assembly while maintaining partial overlap; The wrapping mechanism is used to wrap the second end of the track around the track beam assembly. The stretching and wrapping mechanism pulls the first end of the track to move in the opposite direction of the first direction and lifts and rotates it to dock with the second end of the track. A pin-pressing mechanism, located above the conveyor line, is used to insert an expansion pin into the pin hole at the junction of the first and second ends of the track.

[0006] Furthermore, the stretching and wrapping mechanism includes a crossbeam with two adjustable grippers on it. The crossbeam is rotatably mounted on a support. The support is adjustable on a movable seat in a second and third direction. The movable seat is adjustable on a slide in a first direction. The slide is slidably engaged with the guide mechanism.

[0007] Furthermore, the rounding mechanism includes a main support plate, which is rotatably mounted on a bracket, and the bracket is provided with a first hydraulic cylinder connected to the main support plate; The end of the main support plate is axially connected to the multi-stage support plate. The multi-stage support plate includes a main plate and at least two auxiliary plates. The main plate and the auxiliary plates, as well as adjacent auxiliary plates, are connected by a linkage structure. The bottom of the main support plate is provided with a second hydraulic cylinder connected to the multi-stage support plate. Furthermore, the auxiliary plate includes a first plate and a second plate that slide together, and the linkage structure includes a telescopic rod and a connecting rod that are connected to each other. The end of the telescopic rod is axially connected to the first plate, and the end of the connecting rod is axially connected to the second plate adjacent to the auxiliary plate.

[0008] Furthermore, the pin pressing mechanism includes a mounting base on which a pin pressing cylinder is provided, and a pin shaft lead-out pipe is provided in the direction directly opposite to the pin pressing cylinder; An auxiliary positioning gripper is provided on the inner side wall of the mounting base. The distance between the auxiliary positioning gripper and the expansion pin is controlled by a servo-driven electric cylinder, and the expansion pin is moved by a pneumatic cylinder controlled by the auxiliary positioning gripper.

[0009] Furthermore, the pressing pin mechanism is connected to the truss via a motion mechanism, the motion mechanism including a position adjustment mechanism for driving the pressing pin mechanism to move next to the initial forming track and a synchronous buffer mechanism for reducing vibration transmission when the pressing pin mechanism moves.

[0010] Furthermore, the synchronous buffer mechanism includes an upper support connected to the position adjustment mechanism, the upper support being slidably connected to the lower support via an upper damping structure, the lower support being provided with a lower damping structure connected to the upper damping structure, and the lower support being connected to a pressing pin mechanism.

[0011] Furthermore, the pushing and closing mechanism includes push and closing plates spaced apart, the push and closing plates being slidably disposed on a guide rail arranged along the second direction, and adjacent push and closing plates being connected by a connecting plate, the connecting plate having an L-shaped structure.

[0012] Furthermore, it also includes a holding mechanism provided on the rounding machine. The holding mechanism includes two support arms rotatably connected to the rounding mechanism. A slidable guide rod is provided between the two support arms. A movable holding claw is provided on the guide rod. The holding claw holds and fixes the docking end after docking with each other at both ends of the track.

[0013] The beneficial effects of this invention are reflected in: This invention can automatically complete the entire process from track stretching, wrapping, and automatic pinning, replacing manual assembly and greatly improving assembly efficiency.

[0014] This invention reduces the difficulty of manual alignment and pinning by using a pin-pressing mechanism to complete the pin-pressing operation, resulting in high assembly efficiency and reduced safety hazards.

[0015] This invention uses a wrapping mechanism to wrap one end of the track onto the track beam assembly, so that the track is in a semi-formed state waiting for the other end to be joined. Both ends can be operated simultaneously, further improving the assembly efficiency of the track.

[0016] This invention, through multiple implementations of the encircling mechanism, adapts to track assembly operations with different shapes and encircling sizes, thereby improving the applicability of the assembly system. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 , 2 9 and 10, the present invention provides an automated track assembly system, including a conveyor line 100 on which an AGV trolley 101 is provided for conveying track beam assembly A; Track placement slot 200 is used to place track B; specifically, two track placement slots 200 are symmetrically arranged on both sides of the conveyor line 100, and each has a built-in roller. The stretching and wrapping mechanism 300 is mounted on the guide mechanism 301, which is parallel to the side of the conveyor line 100. The stretching and wrapping mechanism 300 grabs the first end of the track B and moves it along the first direction (i.e., the F1 direction shown in the figure) on the guide mechanism 301 to stretch the track B to a fully unfolded state. The push-and-close mechanism 400 is connected to the guide mechanism 301 and arranged along the second direction (i.e., the F2 direction shown in the figure), and is used to push the unfolded track B to the track beam assembly A and keep it partially overlapping. The wrapping mechanism 500 is used to wrap the second end of track B to track beam assembly A, and the stretching and wrapping mechanism 300 pulls the first end of track B to move in the opposite direction of the first direction and lifts and rotates it to dock with the second end of track B. The pin-pressing mechanism 600 is located above the conveyor line 100 and is used to insert the expansion pin C into the pin hole at the junction of the first and second ends of the track B.

[0021] The specific assembly process of this invention is as follows: The track roll is placed in the track placement groove 200. The stretching and wrapping mechanism 300 moves along the guide mechanism 301 to the front end of the track placement groove 200 and grabs one end of the track roll. The track B is fully stretched out along the first direction. The pushing mechanism 400 pushes the stretched track B to the bottom of the track beam assembly A. Then, the wrapping mechanism 500 and the stretching and wrapping mechanism 300 work synchronously to form the track B onto the track beam assembly A and make the two ends of the track B dock together. Finally, the pressing mechanism 600 inserts the expansion pin C into the docking end of the track B to complete the entire assembly operation. This invention automatically completes the entire process of track stretching, wrapping, and automatic pressing, replacing manual assembly and greatly improving assembly efficiency.

[0022] In one embodiment, please refer to Figure 3 The stretching and wrapping mechanism 300 includes a crossbeam 302, on which two adjustable grippers 303 are provided; specifically, the grippers 303 have slots for contacting the track B; a linear motor is provided on the crossbeam 302 to control the movement of the grippers 303 and adjust the distance between the two grippers 303 according to the width of the track B.

[0023] The crossbeam 302 is rotatably mounted on the bracket 304. Specifically, the crossbeam 302 is rotated by a rotary cylinder or servo motor to adjust the posture of the contact end with the gripper 303 after the track B is unfolded, so that the two ends of the track B can be properly mated.

[0024] The bracket 304 is adjustable on the movable seat 305 in the second and third directions (i.e., direction F3 in the figure). The movable seat 305 is adjustable on the slide table 306 in the first direction. The slide table 306 is slidably engaged with the guide mechanism 301. Specifically, the bracket 304 is adjustable in the second direction to adjust the distance between itself and the track B according to the width of the track B. The slide table 306 is provided with a linear guide rail arranged along the second direction. The bracket 304 is also adjustable in the third direction to adjust the movable height of the gripper 303 according to the inner diameter of the track B. Specifically, the slide table 306 is provided with a lifting mechanism.

[0025] In this embodiment, the slide 306 moves along the first direction to the track B on the guide mechanism 301. According to the width of the track B, the position of the gripper 303 in the second direction is adjusted to control the gripper 303 to hold one end of the track B. Then the track B is unfolded. When the track B is then attached to the track beam assembly A, the height that the gripper 303 can move is adjusted according to the inner diameter of the track B to ensure that the track B can be completely attached to the track beam assembly A.

[0026] In one embodiment, please refer to Figure 4 and Figure 5 The push-fit mechanism 400 includes push-fit plates 401 spaced apart. The push-fit plates 401 are slidably mounted on guide rails 402 arranged along the second direction. A linear motor is mounted on the guide rails 402. Adjacent push-fit plates 401 are connected by connecting plates 403, which have an L-shaped structure.

[0027] In this embodiment, after the track B is fully extended by the stretching and wrapping mechanism 300, the track B is pushed towards the track beam assembly A by the push plate 401 until they partially overlap. During the pushing process, the track B can be straightened, avoiding the problem of local bending due to the excessive length of the track B affecting the assembly accuracy. At the same time, the connecting plate 403 always abuts against one side of the track B during the subsequent assembly process, so that the track B will not be bent, thus improving the accuracy of the subsequent wrapping.

[0028] In one embodiment, please refer to Figure 6 The rounding mechanism 500 includes a main support plate 501, which is rotatably mounted on a bracket 502. The bracket 502 is provided with a first hydraulic cylinder 503 connected to the main support plate 501. The end of the main support plate 501 is axially connected to the multi-stage support plate 504. The multi-stage support plate 504 includes at least two support plates 5041. Adjacent support plates 5041 are connected by a connecting rod structure 505. The bottom of the main support plate 501 is provided with a second hydraulic cylinder 506 connected to the multi-stage support plate 504.

[0029] In this embodiment, after the unfolded track B is pushed under the track beam assembly A, the first hydraulic cylinder 503 and the second hydraulic cylinder 506 operate in sequence. The first hydraulic cylinder 503 retracts, and the second hydraulic cylinder 506 extends, causing the main support plate 501 and the multi-stage support plate 504 to flip into a curved shape, covering one end of the track B onto the track beam assembly A, waiting for the other end to connect.

[0030] In one embodiment, please refer to Figure 7 The rounding mechanism 500 also includes an extension plate 507 with its two ends axially connected to the main support plate 501 and the bracket 502, respectively. The extension plate 507 is controlled to swing by a third hydraulic cylinder 508.

[0031] In this embodiment, the extension plate 507 is configured such that the rounding mechanism 500 can handle situations such as... Figure 17 In the assembly operation of another track B structure shown, when the above-mentioned track B assembly operation is performed, the extension plate 507 is in a straight state and does not participate in the assembly. When the track B structure in this embodiment is assembled, the extension plate 507 is first driven to rotate to a specified angle by the third hydraulic cylinder 508, and then the main support plate 501 and the multi-stage support plate 504 are used to perform the rounding operation.

[0032] Preferably, the extension plate 507 can also be configured with an adjustable length structure to accommodate assembly operations of different sizes of the track B.

[0033] In one embodiment, please refer to Figure 8 The support plate 5041 includes a first plate 50411 and a second plate 50412 that are slidably fitted together. The connecting rod structure 505 includes a telescopic rod 5051 and a connecting rod 5052 that are connected to each other. Specifically, the telescopic rod 5051 can be a cylinder rod. The end of the telescopic rod 5051 is axially connected to the first plate 50411, and the end of the connecting rod 5052 is axially connected to the second plate 50412 of the adjacent auxiliary plate 5042.

[0034] This embodiment is configured in such a way that the diameter of the support plate 5041 can be adjusted according to the rounding size of the track B, accommodating the assembly of more track Bs of different sizes. Specifically, the extension of the telescopic rod 5051 causes the first plate 50411 to extend, thereby adjusting the overall length of the support plate 5041. Since the track B and the track beam assembly A are toothed, once the assembly position is aligned, only an external force in the assembly direction is needed to make the track B fit and connect with the track beam assembly A. That is, the support plate 5041 does not need to present a perfect arc shape when it is rounded to allow the track B to connect with the track beam assembly A.

[0035] In one embodiment, please refer to Figure 11-13The pin pressing mechanism 600 includes a mounting base 601, on which a pin pressing cylinder 602 is provided, and a pin shaft lead-out pipe 603 is provided in the direction directly opposite to the pin pressing cylinder 602. An auxiliary positioning gripper 604 is provided on the inner wall of the mounting base 601. The distance between the auxiliary positioning gripper 604 and the expansion pin C is controlled by a servo-driven electric cylinder 605, and the auxiliary positioning gripper 604 is controlled by a cylinder 606 to move the expansion pin C.

[0036] In this embodiment, after both ends of track B are successfully connected to track beam assembly A, the robotic arm 800 grabs the expansion pin C to the mounting base 601. The auxiliary positioning gripper 604 grabs the expansion pin C, and then controls the pressing mechanism 600 to move to the docking point of track B. The pressing cylinder 602 operates to push the expansion pin C through the pin shaft lead-out tube 603 and insert it into the docking point of track B. During the insertion of the expansion pin C, the auxiliary positioning gripper 604 moves synchronously with the expansion pin C to maintain the gripping and positioning of the expansion pin C until the expansion pin C is inserted to half the position of track B. Then, the auxiliary positioning gripper 604 releases, and the pressing cylinder 602 continues to operate until the expansion pin C is completely pressed into track B, completing the entire track B assembly operation.

[0037] In one embodiment, please refer to Figure 12 and Figure 15 The pin-pressing mechanism 600 is connected to the truss 700 via a motion mechanism. The motion mechanism includes a position adjustment mechanism 610 for moving the pin-pressing mechanism 600 to the side of the initial track B and a synchronous buffer mechanism 620 for reducing vibration transmission when the pin-pressing mechanism 600 moves.

[0038] In this embodiment, after both ends of track B are successfully connected to track beam assembly A and the pin pressing mechanism 600 grabs the expansion pin C, the pin pressing mechanism 600 is driven to the assembly position by the position adjustment mechanism 610 to complete the pin pressing operation.

[0039] Specifically, the position adjustment mechanism 610 includes a frame 611 connected to the truss 700, a slide 612 movably connected to the frame 611, a movable column 613 on the slide 612, and a vertical rack on the movable column 613. The vertical rack is driven by a motor and a gear set to drive the pressing pin mechanism 600 to adjust its height. The truss 700 is provided with a horizontal rack, which is also driven by a motor and a gear set to drive the pressing pin mechanism 600 to move horizontally.

[0040] In one embodiment, please refer to Figure 14 The synchronous buffer mechanism 620 includes an upper support 621 connected to the position adjustment mechanism 610. The upper support 621 is slidably connected to the lower support 623 through an upper damping structure 622. The lower support 623 is provided with a lower damping structure 624 connected to the upper damping structure 622, and the lower support 623 is connected to the pressing pin mechanism 600.

[0041] Specifically, the upper damping structure 622 includes a damping rod, and a strong spring is sleeved on the outside of the damping rod; a sliding groove is provided on the lower support 623, and the upper damping structure 622 is connected to the lower damping structure 624 through a slider, wherein the upper damping structure 622 and the lower damping structure 624 have the same structure.

[0042] In this embodiment, the pin-pressing mechanism 600 is configured such that when it is performing the pin-pressing operation, the cooperation between the upper damping structure 622 and the lower damping structure 624 can reduce the lateral and vertical vibration forces generated during the operation, avoid transmitting reaction forces to the truss 700, ensure the structural stability of the truss 700, and thus ensure the stability of the pin-pressing operation.

[0043] In one embodiment, please refer to Figure 16 It also includes a holding mechanism 510 disposed on the rounding mechanism 500. The holding mechanism 510 includes two support arms 511 rotatably connected to the rounding mechanism 500. A slidable guide rod 512 is provided between the two support arms 511. A movable holding claw 513 is provided on the guide rod 512. After the holding claw 513 is connected to each other at both ends of the track B, it holds and fixes the docking end.

[0044] Specifically, the rotation of the support arm 511 can be achieved by a servo motor; the sliding of the guide rod 512 can be achieved by a linear motor; the approach and departure of the gripping claw 513 can be achieved by a cylinder; the above only gives common driving methods, and the above motion requirements can also be achieved by other structures.

[0045] In this embodiment, after the two ends of track B are connected, the support arm 511 is driven to rotate so that the guide rod 512 is on the same plane as the connection point. Then, the guide rod 512 is driven to slide along the support arm 511 to the connection point. Finally, the gripping claw 513 is driven to move along the guide rod 512 until the track B is gripped and fixed from both sides. This avoids the problem that the lateral force generated during the subsequent pressing pin operation will cause positional deviation at both ends of track B, which would make it difficult for the expansion pin C to be properly inserted into the connection end of track B.

[0046] It should be noted that if the embodiments of the present invention involve directional indicators such as up, down, left, right, front, back, etc., the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicators will also change accordingly.

[0047] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied. Furthermore, "multiple" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
