Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a conveying equipment for an automotive body-in-white welding production line. Background Technology

[0002] The main function of the conveying equipment in the automotive body-in-white welding production line is to transfer workpieces, components, and body-in-white from different workstations to various welding and assembly processes through an efficient and stable conveying system. The conveying equipment in the automotive body-in-white welding production line also needs to continuously adapt to new vehicle models and material requirements to promote green manufacturing and efficient production.

[0003] Existing automotive body-in-white welding production line conveying equipment, such as the one disclosed in announcement number CN220073651U, uses a conveying mechanism. This mechanism includes a movable frame located inside the connecting frame and multiple sets of movable wheels distributed on the movable frame. The movable wheels roll on the guide rod. However, this device cannot meet the requirements for conveying different parts of the automotive body-in-white and different models of automotive body-in-white. Most importantly, welding is carried out during the conveying of the automotive body-in-white, which requires a high degree of precision. However, the existing conveying method is difficult to convey the automotive body-in-white in an orderly manner, especially in terms of linear movement of the automotive body-in-white during the conveying process, making it impossible to ensure that the automotive body-in-white can move accurately to the welding processing position. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a conveying equipment for an automotive body-in-white welding production line.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A conveying device for an automotive body-in-white welding production line includes a body with a conveying plate movably mounted on it for supporting the automotive body-in-white. A guide rail for the conveying plate is integrally connected to the upper end of the body, and rectangular holes symmetrically distributed on both sides of the guide rail are provided on the upper end of the body. A support plate is integrally connected to the outer wall of the body, and a drive motor is fixedly mounted on the support plate. A stepping feeding assembly for conveying the automotive body-in-white is provided on the body via the drive motor and the conveying plate. Mounting supports are symmetrically welded to the front and rear sides of the upper end of the body, and limiting components for guiding and supporting the automotive body-in-white from the front and rear sides are provided on the body via the mounting supports.

[0007] To better achieve the above objectives, the present invention adopts a further technical solution: the feeding assembly includes a rotating shaft rotatably installed in the machine body and fixedly connected to the output end of the active motor; an eccentrically mounted cam is fixedly installed on the rotating shaft; a driving component for intermittently contacting the top of the conveying long plate, which has an arc-shaped rack at the top; a limiting groove is provided at the lower end of the driving component; a fixed shaft is fixedly installed in the machine body and slidably mounted in the limiting groove; a straight rack is provided at the lower end of the conveying long plate; and an arc-shaped rack that movably engages with the straight rack is provided at the upper end of the driving component.

[0008] To better achieve the above objectives, the present invention adopts a further technical solution: the limiting component includes a guide rod fixedly connected between the machine body and the mounting support, and a strong spring is welded on the mounting support. The strong spring is fitted onto the guide rod, and a limiting plate is fixedly connected to the strong spring and slidably fitted onto the guide rod. A fixing block that moves to abut against the conveying plate is fixedly connected to the limiting plate.

[0009] The advantages of this utility model are:

[0010] The drive component is driven by an active motor to perform a periodic reciprocating deflection motion, and matching arc-shaped racks and straight racks are set on the drive component and the conveyor plate, so that the conveyor plate can perform step-by-step feeding of the car body in the intermittent movement process.

[0011] The limiting plate will limit the position of the conveyor plate. If there is a slight deviation in the position of the conveyor plate when it is moved onto the machine body, the limiting plate will gradually adjust the position and state of the conveyor plate under the action of the strong spring and the mounting bracket.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Reference Figures 1-4 A conveying device for an automotive body-in-white welding production line includes a body 1. A conveying plate 6 for supporting the automotive body-in-white is movably mounted on the body 1. The automotive body-in-white is fixed on the conveying plate 6. A support plate 4 is integrally connected to the outer wall of the body 1. A drive motor 5 is fixedly mounted on the support plate 4. A guide rail for the conveying plate 6 is integrally connected to the upper end of the body 1, and rectangular holes 2 symmetrically distributed on both sides of the guide rail are opened at the upper end of the body 1. A stepping feeding assembly for conveying the automotive body-in-white is provided between the body 1 and the conveying plate 6 via the drive motor 5. The feeding assembly includes a rotating shaft 9 rotatably mounted in the body 1 and fixedly connected to the output end of the drive motor 5. An eccentrically mounted cam 10 is fixedly mounted on the rotating shaft 9. An arc-shaped cam is movably fitted on the cam 10 for intermittently contacting the top of the conveying plate 6. The drive component 8 of the rack has a limiting groove 11 at its lower end. A fixed shaft 12, which is slidably fitted into the limiting groove 11, is fixedly installed inside the body 1. A straight rack is provided at the lower end of the conveying plate 6, and an arc-shaped rack that engages with the straight rack is provided at the upper end of the drive component 8. When the arc-shaped rack moves upward at an angle, it contacts the conveying plate 6 through the straight rack and applies a thrust to the conveying plate 6, causing the conveying plate 6 to move linearly along the guide rail. The active motor 5 is started and runs. The output end of the active motor 5 drives the rotating shaft 9 to rotate, thereby pulling the cam 10, which is fixedly connected to the rotating shaft 9, to rotate. The rotation of the cam 10 pulls the drive component 8 to move. During the movement of the drive component 8, the arc-shaped rack at the upper end engages with the straight rack at the lower end of the conveying plate 6, pushing the conveying plate 6 to move horizontally.

[0019] The upper end of the machine body 1 is symmetrically welded with mounting supports 3 on the front and rear sides. The machine body 1 is equipped with a limiting component for guiding and supporting the car body from the front and rear sides through the mounting supports 3. The limiting component includes a guide rod 13 fixedly connected between the machine body 1 and the mounting supports 3. A strong spring 14 is welded on the mounting supports 3. The strong spring 14 is fitted on the guide rod 13. A limiting plate 7 is fixedly connected to the strong spring 14 and slidably fitted on the guide rod 13. A fixing block 15 that moves to abut against the conveying long plate 6 is fixedly connected to the limiting plate 7. Because the position of the car body in white on the conveyor plate 6 is offset, and the conveyor plate 6 will shake and vibrate due to the force during the meshing of the arc rack and the straight rack, the limiting plate 7 is used to dynamically limit the conveyor plate 6. The limiting plate 7 will press the conveyor plate 6, and the strong spring 14 allows the limiting plate 7 to have room for movement in the vertical direction. The guide rod 13 restricts the movement direction of the limiting plate 7 to the vertical direction. Under the vertical downward pressure of the vertically movable limiting plate 7, the conveyor plate 6 will smoothly adjust its movement posture.

[0020] In this utility model, the specific model and specifications of the active motor 5 need to be selected and determined according to the actual specifications, etc. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0021] In use, the car body is fixed on the conveyor plate 6. The car body to be welded and the conveyor plate 6 are smoothly conveyed to the machine body 1. The limiting plates 7 on both sides of the upper part of the machine body 1 will contact the two sides of the conveyor plate 6. The position of the conveyor plate 6 when it is first conveyed to the machine body 1 is slightly deviated, and it will be gradually adjusted under the action of the limiting plates 7. The active motor 5 is started. The output end of the active motor 5 drives the cam 10 to rotate through the rotating shaft 9. Because of the limiting effect of the fixed shaft 12 on the drive component 8, the drive component 8 performs a deflection lifting motion. When the arc rack and the straight rack are engaged, the horizontally moving conveyor plate 6 carries the car body and moves smoothly.
