Description

Technical Field

[0001] This invention belongs to the technical field of tooling and auxiliary equipment, specifically a top cover beam precision positioning device and method. Background Technology

[0002] With the continuous development of automotive intelligent technology, more and more automakers are accelerating their intelligent transformation, launching intelligent models to provide consumers with a more intelligent and user-friendly driving experience. The installation of many intelligent modular devices requires the design of mounting brackets, holes, nuts, studs, etc., on the roof crossbeams. These installation requirements place high precision demands on the relative positions of the roof crossbeams. High-end models typically have 5 to 7 roof crossbeams. During the assembly of these crossbeams, it is crucial not only to ensure the precision of each crossbeam relative to the vehicle body but also to guarantee the relative positional precision of multiple crossbeams requiring installation.

[0003] CN211937646U discloses an adhesive application system for automotive roof crossbeams, including an adhesive application platform. A three-dimensional moving mechanism is installed on the platform, and a pneumatic glue gun and a height sensor are mounted on the mechanism for synchronous movement. The signal output of the height sensor is electrically connected to the signal input of a microcontroller, and the control output of the microcontroller is electrically connected to the control input of the pneumatic glue gun. This technical solution lacks the function of assembling and positioning the roof crossbeams to the vehicle body, and cannot guarantee the relative positional accuracy of multiple crossbeams on the body-in-white.

[0004] CN211707290U discloses a gluing table for a side panel top cover crossbeam overlap reinforcement, which includes a left side wall folded edge support column of the side panel top cover crossbeam overlap reinforcement disposed on a workbench; a right side wall folded edge support column of the side panel top cover crossbeam overlap reinforcement disposed on a workbench; a positioning post assembly for the side panel top cover crossbeam overlap reinforcement with positioning hole II disposed at the rear of the workbench; a positioning post assembly for the side panel top cover crossbeam overlap reinforcement with positioning hole I disposed at the front of the workbench; a side wall folded edge pressing part of the side panel top cover crossbeam overlap reinforcement disposed at the rear of the workbench via a folding mechanism; a front folded edge pressing part support table disposed at the front edge of the workbench, which detachably mounts the front folded edge pressing part of the side panel top cover crossbeam overlap reinforcement; and a bottom rear inclined plate support column of the side panel top cover crossbeam overlap reinforcement disposed at the rear of the tooling table and located on both sides of the positioning post for the side panel top cover crossbeam overlap reinforcement with positioning hole II. This technical solution provides a gluing station for the overlapping reinforcement of the side roof beams, which has a simple structure and facilitates the fixing of the workpiece to be glued. However, this technical solution lacks the functions of loading, assembly, and positioning, and cannot guarantee the relative positional accuracy of multiple beams in the body-in-white.

[0005] In a welding workshop production line, the assembly process for the roof crossbeams is as follows: After completing the assembly and connection of the lower body and side panels, before installing the roof, seven roof crossbeams need to be assembled onto the side panels. These crossbeams are then positioned and clamped using tooling before spot welding. The two middle crossbeams provide mounting holes for the vehicle's intelligent connectivity module. The accuracy between these two middle crossbeams and the vehicle body must meet ±0.5mm, and the relative positional accuracy of the two crossbeams must meet ±0.1mm. The middle roof crossbeams are installed manually, requiring manual application of adhesive before assembly. Summary of the Invention

[0006] To address the above problems, this invention provides a top cover crossbeam precision positioning device and method, including a BASE component and multiple part positioning and clamping components. The BASE component includes a BASE welded frame, a valve island, a gun changing disc, and tooling positioning and clamping components. The BASE welded frame includes an H-shaped frame body, a first pin sleeve, and positioning support blocks. The tooling positioning and clamping components are fixed at the four corners of the H-shaped frame body. The gun changing disc is located at the center of the H-shaped frame body. The valve island is located on the H-shaped frame body. The H-shaped frame body is provided with multiple pin sleeves and multiple positioning support blocks. The tooling positioning and clamping components include a first pin sleeve, a first pin sleeve, and multiple positioning support blocks. The tooling positioning and clamping component and the second tooling positioning and clamping component are fixed to the H-shaped frame body. This invention enables the gluing function of the middle crossbeam of the top cover to be completed on the loading table; it ensures the relative positional accuracy of the middle crossbeam of the top cover; it ensures the stability and fixation of the worktable position for manual loading and gluing; it ensures the positional accuracy of the device of this invention with the main welding and main assembly side frame, thereby ensuring the assembly positional accuracy of the middle crossbeam of the top cover with the car body; it ensures the accurate positioning of the device of this invention on the bracket, thereby ensuring the repeatability of the positional accuracy when the robot carries the gun changing plate to grasp. The positioning device and method of this invention are described in terms of realizing the loading, gluing, assembly and positioning functions of two middle crossbeams of the top cover.

[0040] The gun-changing plate 13 is used to connect the robot to the positioning device of the present invention.

[0041] The first pin sleeve 112 is used to fix the positioning device of the present invention on the docking station, and the second pin sleeve 121 is used to position the main welding column with the tooling.

[0047] Two types of tooling positioning and clamping components are arranged diagonally to realize the positioning and connection of the device of the present invention with the main welding and main assembly side frame fixture, forming part of the main welding and main assembly fixture, and ensuring the positional accuracy of the middle crossbeam of the roof and the vehicle body.

[0049] A method for precisely positioning a top cover beam includes the following steps:

[0050] The two intermediate crossbeams of the roof are manually placed onto the part positioning and clamping component 2 of the device according to the positioning pin positions, and glue is applied manually.

The BASE component 1 of the device is positioned and connected to the side frame gripper. After the detection switch recognizes the device in place, the positioning work of the intermediate crossbeams between the body and the roof begins.

[0051] Multiple part positioning and clamping components 2 enable the loading and gluing of the top cover middle crossbeam on the loading platform; the part positioning and clamping components 2 and BASE component 1 are precisely positioned and connected by BASE welding frame 11, ensuring the relative positional accuracy of the top cover middle crossbeam; the part positioning and clamping components 2 have positioning pins 25 for positioning support, which can ensure the stability and fixation of the worktable position during manual loading and gluing; the BASE welding frame 11 in BASE component 1 can ensure the positional accuracy of the device of the present invention and the main welding and main assembly side frame, thereby ensuring the assembly positional accuracy of the top cover middle crossbeam and the vehicle body; the BASE welding frame 11 has precision-machined positioning surface positioning support block 113 and first pin sleeve 112, which can ensure the accurate positioning of the device of the present invention on the bracket, thereby ensuring the repeatability of the positional accuracy when the robot carries the gun changing plate to grasp.
