Description

Technical Field

[0001] The present invention relates to the technical field of conveying systems, and particularly relates to an intelligent conveying system for continuous processing of vehicle frames. Background Art

[0002] During the processing of vehicle frames, the conveying of vehicle frames is a key link. There are many problems in traditional vehicle frame conveying systems.

[0003] On the one hand, a conventional suspension system only relies on a single suspension rope or suspension hook for suspension. For a vehicle frame with a large mass, its torque is small, making it difficult to drive the vehicle frame to rotate freely and unable to meet the requirement of flexibly adjusting the posture of the vehicle frame during conveying.

[0004] On the other hand, the designs of the tracks and moving parts of some conveying systems are not reasonable enough. When the moving parts move on the tracks, the stability is poor, and it is easy to shake or deviate, resulting in the vehicle frame not being accurately conveyed to the designated position, affecting the processing accuracy and efficiency.

[0005] Moreover, traditional conveying systems often lack a reasonable plan for the path of the suspension rope, and problems such as winding are likely to occur during the telescopic process of the suspension rope. Therefore, the present invention provides an intelligent conveying system for continuous processing of vehicle frames to solve the above problems. Summary of the Invention

[0006] Aiming at the above existing technical deficiencies, the purpose of the present invention is to provide an intelligent conveying system for continuous processing of vehicle frames to improve the stability of vehicle frame suspension and facilitate the rotation of the vehicle frame.

[0007] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides an intelligent conveying system for continuous processing of vehicle frames, including: Tracks, on which a plurality of moving parts are arranged along the conveying direction; A turntable, which is rotatably installed on the moving part; Wherein, two centrally symmetric support arms are fixed on the turntable, a first suspension rope for suspending the vehicle frame is connected to the middle of the turntable, and second suspension ropes for suspending the vehicle frame are connected to the ends of the two support arms. Both the first suspension rope and the second suspension rope can be scaled.

[0008] Preferably, the moving part further includes a fixed disk, the bottom of the fixed disk is connected with a hanging disk, a first winch is rotatably installed inside the hanging disk, the first suspension rope is wound around the first winch, a first rope outlet is provided below the hanging disk, and the end of the first suspension rope extends to the outside from the rope outlet.

[0009] Preferably, connection heads are fixed to the ends of both support arms far away from the turntable. A second winch is rotatably installed inside the connection head. The second suspension rope is wound around the second winch. A second rope outlet is formed at one end of the support arm close to the support head. The two second suspension ropes extend to the outside from the two second rope outlets respectively.

[0010] Preferably, the turntable and the two support arms are of an integrally formed structure. Through holes are provided inside the turntable and the two support arms. One end of the through hole extends to the inside of the corresponding connection head, and the other end passes through the corresponding side support arm and the turntable and communicates with the second rope outlet on the other support arm. The second suspension rope passes through the corresponding through hole and extends outwards from the second rope outlet on the side far away from the connection head.

[0011] Preferably, a slideway arranged along the conveying direction is provided inside the track. The moving member includes a slider slidably installed inside the slideway. A movable hinge is connected inside the slideway. The slider is connected to the hinge.

[0012] Preferably, teeth are provided at the outer circumference of the fixed disk. A gear is rotatably installed inside the turntable. The gear meshes with the teeth on the fixed disk.

[0013] Preferably, rollers are rotatably installed on both sides of the slider. The rollers are rotatably installed inside the slideway.

[0014] Preferably, positioning grooves are provided on both sides of the track. Arc plates are fixed to both sides of the fixed disk. A telescopic frame is fixed to the arc plate. A pressing wheel is rotatably installed at the end of the telescopic frame. The pressing wheel presses inside the positioning groove.

[0015] Preferably, hooks for hanging the vehicle frame are installed at the ends of the first suspension rope and the second suspension rope.

[0016] Preferably, a first motor for driving the first winch inside to rotate is fixed to the suspension disk. A second motor for driving the second winch inside to rotate is fixed to the connection head. A third motor for driving the gear to rotate is fixed to the turntable.

[0017] The beneficial effects of the present invention are as follows: The turntable and the moving member are connected by a bearing and can rotate freely, capable of flexibly adjusting the hanging direction of the vehicle frame. Cooperating with the movement of the moving member on the track, the vehicle frame can change its posture during the conveying process according to the processing requirements, meeting the requirements of different processing procedures for the position and angle of the vehicle frame. The frame is suspended at three points by the first suspension rope and two second suspension ropes, which increases the torque. Compared with the conventional single suspension rope or suspension hook, it can easily drive the heavier frame to rotate freely. Moreover, both the first suspension rope and the second suspension rope have the function of scaling. The operator can conveniently stretch the suspension rope to connect with the frame and then contract the suspension rope to achieve stable lifting and transportation. Through holes are provided inside the turntable and the support arm, and the second suspension rope passes through the through holes and extends out from the second rope outlet. During the telescopic process of the second suspension rope, the through holes guide its direction, making it smoother and avoiding problems such as entanglement, ensuring the stability of the system operation. At the same time, the second suspension rope passes through the entire turntable and support arm, and the acting force is more evenly distributed during suspension, reducing the force on the end of the support arm and lowering the risk of the support arm being bent, making the suspension more balanced.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following uses specific embodiments to illustrate the present invention, but it is not a limitation to the invention.

[0026] Embodiment 1 As Figures 1 - 7 shown, in this embodiment, an intelligent conveying system for continuous processing of a frame is provided, including a track 1 and a turntable 2.

[0027] A plurality of movable parts arranged along the conveying direction are installed on the track 1, and the track 1 is suspended in mid-air by means of a bracket. The movable parts are installed on the track 1 by means of a hinge connection, and can move along the track 1. The installation method of the track 1 belongs to common technology, so it is not described in detail in the present invention. Specifically, it is only necessary to install a movable hinge inside the track 1, and then connect a plurality of movable parts to different positions of the hinge respectively, so that as the hinge moves, the movable parts will also move accordingly, providing a basic platform for the movement of subsequent components, so that the entire conveying process can be carried out along the preset track 1, and the accuracy and stability of the conveying path are ensured.

[0028] The turntable 2 is rotatably mounted on the moving part. The turntable 2 and the moving part are connected by bearings and can rotate freely to achieve flexible adjustment of the frame suspension direction. In conjunction with the movement of the moving part on the track 1, the frame can change its posture according to processing requirements during transportation.

[0029] Among them, two centrally symmetrical support arms 3 are fixed on the turntable 2, and the middle part of the turntable 2 is connected with a first suspension rope 4 for hanging the frame, and the ends of the two support arms 3 are connected with a second suspension rope 5 for hanging the frame. The first suspension rope 4 and the second suspension rope 5 can both be scaled. Since the frame itself has a large mass, and the conventional suspension system only relies on a single suspension rope or a suspension hook for suspension, its torque is small, and it is difficult to drive the heavy frame to rotate freely. Different from this, the present system uses the first suspension rope 4 and two second suspension ropes 5 to suspend the frame at three points. This suspension method can effectively increase the torque and easily drive the frame to rotate. In addition, the first suspension rope 4 and the second suspension rope 5 both have a scaling function. The operator can first lengthen the suspension rope and connect it to the frame, and then shrink the suspension rope to achieve a stable suspension of the frame.

[0030] Embodiment 2 like Figures 1 - 7 As shown, based on the first embodiment, this embodiment provides a driving method of the suspension rope, which is as follows: The movable part also includes a fixed plate 9, the bottom of which is connected to a hanging plate 10, a first winch 14 is rotatably installed inside the hanging plate 10, a first lifting rope 4 is wound around the first winch 14, a first rope outlet is provided below the hanging plate 10, an end of the first lifting rope 4 extends from the rope outlet to the outside, when the first winch 14 rotates, the first lifting rope 4 will be wound or loosened accordingly, and the first lifting rope 4 can be extended and retracted through the first rope outlet below the hanging plate 10, and the rotation of the first winch 14 can be controlled to accurately realize the scaling function of the first lifting rope 4, thereby providing a stable structural support for the lifting and lowering operations of the frame, ensuring that the first lifting rope 4 can be flexibly extended and retracted as required.

[0031] At one end of the two support arms 3 away from the turntable 2, connecting heads 7 are fixedly installed. Inside the connecting heads 7, second winches 17 are rotatably installed. The second suspension ropes 5 are wound around the second winches 17. At one end of the support arm 3 close to the support head, a second rope outlet is provided. The two second suspension ropes 5 extend to the outside from the two second rope outlets respectively. When the second winch 17 rotates, the second suspension rope 5 will wind or unwind on the second winch 17, and telescopic movement is achieved through the second rope outlet at one end of the support arm 3 close to the support head. The telescopic movement of the second suspension rope 5 can be precisely controlled. Cooperating with the first suspension rope 4, the three-point suspension and lifting operations of the vehicle frame are jointly completed, enhancing the control ability of the system for the suspension and lifting of the vehicle frame.

[0032] The turntable 2 and the two support arms 3 are of an integrally formed structure. Through holes are provided inside both the turntable 2 and the two support arms 3. One end of the through hole extends to the inside of the corresponding connecting head 7, and the other end passes through the corresponding side support arm 3 and the turntable 2 and communicates with the second rope outlet on the other support arm 3. The second suspension rope 5 passes through the corresponding through hole and extends outwards from the second rope outlet on the side away from the connecting head 7. During the telescopic movement of the second suspension rope 5, its path can be guided through the through hole, reasonably planning the path of the second suspension rope 5, making the telescopic movement of the second suspension rope 5 smoother, avoiding problems such as winding, ensuring the stability of the system operation. At the same time, the second suspension rope 5 passes through the entire turntable 2 and the support arm 3, enabling the acting force to act on the turntable 2 and the support arm 3 during suspension, rather than acting solely on the end of the support arm 3, reducing the force received by the support arm 3 and the risk of the support arm 3 being bent, and making it easier to make the suspension more balanced.

[0033] At the ends of both the first suspension rope 4 and the second suspension rope 5, hooks for suspending the vehicle frame are installed. Through the hanging action of the hooks, the vehicle frame is connected to the suspension ropes, conveniently and quickly realizing the connection between the vehicle frame and the suspension ropes, making the suspension and disassembly operations of the vehicle frame more convenient and improving the use efficiency of the system.

[0034] A first motor 11 for driving the internal first winch 14 to rotate is fixedly installed on the suspension disc 10, a second motor 15 for driving the internal second winch 17 to rotate is fixedly installed on the connecting head 7, and a third motor 6 for driving the gear 16 to rotate is fixedly installed on the turntable 2, providing power for the telescopic movement of the first suspension rope 4 and the second suspension rope 5 and the rotation of the fixed disc 9, enabling the entire system to achieve automated operation and improving the efficiency and accuracy of vehicle frame transportation and processing.

[0035] Embodiment Three As Figures 1 - 7 shown, on the basis of Embodiment One and Embodiment Two, this embodiment provides a driving method for the moving part, specifically as follows: The inside of the track 1 is provided with a slideway arranged along the conveying direction. The moving part includes a slider 13 slidably installed inside the slideway. A movable hinge is connected inside the slideway, and the slider 13 is connected to the hinge. When the hinge moves, it drives the slider 13 to slide inside the slideway, thereby realizing the movement of the moving part along the track 1. It provides a stable sliding track 1 for the moving part, ensuring that the moving part can accurately move along the preset direction of the track 1. It is the basic structure for the entire conveying system to realize the continuous conveying of the vehicle frame.

[0036] Tooth teeth are provided at the outer circle of the fixed disk 9. A gear is rotatably installed inside the turntable 2, and the gear meshes with the tooth teeth on the fixed disk 9. When the gear rotates, it drives the fixed disk 9 meshed with it to rotate, thereby affecting the position and angle of the hanging disk 10 and the first suspension rope 4 connected to it. Through the transmission of the gear and the tooth teeth, the rotation of the fixed disk 9 is controlled.

[0037] Rollers are rotatably installed on both sides of the slider 13, and the rollers are rollingly installed inside the slideway. When the slider 13 moves inside the slideway, the rollers can reduce the friction between the slider 13 and the slideway, make the movement of the slider 13 smoother, reduce the resistance when the moving part moves on the track 1, improve the moving efficiency of the moving part, reduce energy loss, and at the same time reduce the wear between components and extend the service life of the system.

[0038] Positioning grooves are provided on both sides of the track 1. Arc plates 8 are fixed on both sides of the fixed disk 9. A telescopic frame is fixed on the arc plate 8. A pressing wheel 12 is rotatably installed at the end of the telescopic frame. The pressing wheel 12 presses inside the positioning groove. The telescopic frame can adjust the position of the pressing wheel 12 to make it tightly press inside the positioning groove, maintain stability during the movement of the moving part, enhance the stability and positioning accuracy of the moving part when moving on the track 1, prevent the moving part from shaking or shifting during the movement, and ensure that the vehicle frame can be accurately conveyed to the designated position. Especially when the fixed disk 9 passes through the curved position of the track 1, it can prevent the fixed disk 9 from tilting.

[0039] Working principle: A movable hinge is installed inside the track 1, and the moving part is connected to the track 1 through the hinge. When the hinge moves, it drives the connected slider 13 to slide inside the track 1 along the slideway arranged in the conveying direction, thereby realizing the movement of the moving part along the track 1. The rollers on the moving part roll inside the slideway, reducing the friction during movement and making the movement smoother. At the same time, positioning grooves are provided on both sides of the track 1, and the arc plates 8 on both sides of the fixed disk 9 are pressed inside the positioning grooves by the pressing wheels 12 connected through the telescopic frame, ensuring the stability and positioning accuracy of the moving part during movement. The turntable 2 is rotatably installed on the moving part and connected to the moving part through a bearing, allowing free rotation. The turntable 2 and the two support arms 3 are of an integrally formed structure, and two centrally symmetric support arms 3 are fixed on the turntable 2. A first lifting rope 4 is connected to the middle of the turntable 2, and second lifting ropes 5 are connected to the ends of the two support arms 3. By driving the first winch 14 in the hanging plate 10 to rotate through the first motor 11, the winding or loosening of the first lifting rope 4 is achieved, and the telescoping is realized from the first rope outlet; by driving the second winch 17 in the connector 7 to rotate through the second motor 15, the winding or loosening of the second lifting ropes 5 on the second winch 17 is achieved, and the telescoping is realized from the second rope outlet. The operator first lengthens the lifting ropes to connect with the vehicle frame, and then contracts the lifting ropes to achieve the stable lifting of the vehicle frame. The vehicle frame is three-point suspended by the first lifting rope 4 and two second lifting ropes 5. Since the vehicle frame has a large mass, the three-point suspension method increases the torque and can easily drive the vehicle frame to rotate. During the conveying process, the moving part moves along the track 1, and the turntable 2 rotates freely according to the processing requirements, thereby changing the suspension direction and attitude of the vehicle frame to cooperate with the processing flow. At the same time, the third motor 6 drives the gears in the turntable 2 to rotate, and the gears mesh with the teeth on the outer circle of the fixed disk 9 to drive the fixed disk 9 to rotate, further adjusting the position and angle of the first lifting rope 4 and the vehicle frame.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or equivalently replaced. Any modification or partial replacement without departing from the spirit and scope of the present invention shall be covered by the scope of the claims of the present invention.
