Description

Technical Field

[0001] This utility model relates to the field of automated production, and in particular to a flipping device that can achieve sliding adjustment. Background Technology

[0002] In industrial production, it is often necessary to drive large workpieces to rotate in space, changing their posture to facilitate operation at the execution end, such as in automated welding and assembly. In the welding station for the battery casing of new energy vehicles, the battery casing is generally welded from multiple horizontal and vertical beams. This requires welding at multiple angles and positions on the top, bottom, left, right, inside, and outside of the battery casing. Due to the limitations of robots and fixtures in traditional structures, performing such multi-angle, multi-position welding at a single station is very cumbersome. Sometimes, it is even necessary to have the robot lower the workpiece after partially welding it and then clamp it from another angle to complete the entire welding operation. This not only increases the workload but also seriously affects welding efficiency.

[0003] Meanwhile, battery casings come in various specifications, and the width, length, and other parameters of the casings differ for different battery specifications. If a separate device is set up for each type of battery casing to change its spatial orientation, it will greatly increase the company's operating costs.

[0004] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention

[0005] This invention addresses the aforementioned shortcomings of existing technologies by proposing a simple, ingeniously designed, and rationally laid-out flipping device capable of rotating large and heavy parts in space and adapting to workpieces of various lengths and specifications.

A pressure roller 13 is rotatably supported on the top of the support plate 12, and a lateral guide roller 14 is rotatably supported in the middle of the support plate 12.

The C-shaped flipping body 6 is also equipped with a workpiece clamping mechanism. The structure of the sliding flipping mechanism 2 is the same as that of the fixed flipping mechanism 1. The difference is that the base 3 of the sliding flipping mechanism 2 is slidably connected to the bottom support plate 16 through the sliding rail 15. A rack 17 is also fixedly installed on the bottom support plate 16. A sliding motor housing 18 is also installed on the base 3 of the sliding flipping mechanism 2. A sliding motor is installed inside the sliding motor housing 18. The working end of the sliding motor is provided with a second active tooth that meshes with the rack 17.

[0018] The workpiece clamping mechanism includes a clamping mechanism mounting frame 19 disposed within a C-shaped flipping body 6. A clamping slide rail 20 is disposed within the clamping mechanism mounting frame 19. Two slide blocks 21 are slidably connected to the clamping slide rail 20. Each slide block 21 is provided with a gripper 22, and the two grippers 22 are symmetrically distributed. A clamping motor 23 is disposed on the bottom surface of the clamping mechanism mounting frame 19.

The two slide blocks 21 are respectively threadedly connected to the lead screw portions at both ends of the bidirectional lead screw 24 with opposite rotation directions.

[0019] The inner side of the gripper 22 is provided with a plurality of equally spaced rubber clamping blocks 25.

[0020] The clamping mechanism mounting frame 19 is provided with a guide square steel 26, and the gripper 22 is provided with a guide square hole that matches the guide square steel 26.

[0021] Both ends of the bottom support plate 16 are provided with limit blocks 27, which can contact the collision block provided on the bottom surface of the base 3 in the sliding and flipping mechanism 2.

[0022] The working process of the flipping device that can achieve sliding adjustment in this embodiment of the utility model is as follows: When welding operations are required on certain large workpieces or structures, the workpieces are lifted by a lifting tool and placed on the flipping device. The device drives the workpieces to flip in space. Through the coordinated action with the welding robot, all welding operations are achieved in one clamping. The following describes the working process of this device using the automated welding operation of the battery casing of a new energy vehicle as an example. First, according to the overall length of the battery casing, the relative distance between the base 3 and the fixed flipping mechanism 1 in the sliding flipping mechanism 2 is changed. After the sliding flipping mechanism 2 is adjusted to a suitable state, the battery casing is lifted to the top of this device using a lifting device. The two ends of the battery casing are supported by the fixed flipping mechanism 1 and the sliding flipping mechanism 2 respectively. Then, the workpiece clamping mechanism in the two flipping mechanisms is activated to clamp it. Then, by controlling the two sets of flipping mechanisms to rotate synchronously, the battery casing can be flipped in space to change its posture in order to cooperate with the welding robot to perform welding operations. The operation process of the above-mentioned workpiece clamping mechanism is as follows: The control system sends a signal to the clamping motor 23. The output end of the clamping motor 23 drives the bidirectional lead screw 24 to rotate at a constant speed through the gear transmission pair. Since both ends of the bidirectional lead screw 24 are threadedly connected to the slides 21, and the threads of the two slides 21 are in opposite directions, when the bidirectional lead screw 24 rotates, the slides 21 move towards each other (or away from each other), realizing the opening and closing action of the two grippers 22. When the two grippers 22 move towards each other, they clamp onto the two side walls of the battery casing respectively. Multiple rubber clamping blocks 25 contact the side walls of the battery casing, providing sufficient friction while also preventing the side walls of the battery casing from being scratched. During the reciprocating motion of the grippers 22 driven by the slides 21, since the grippers 22 are provided with guide square holes that match the guide square steel 26, the guide square steel 26 can ensure the stability of the grippers 22 during movement. When the workpiece being clamped needs to be rotated in space to change its posture, the control system sends a signal to the servo motors in the fixed rotating mechanism 1 and the sliding rotating mechanism 2. The servo motors work and drive the C-shaped gear ring 7 to move through the active gear, thereby driving the C-shaped rotating body 6 to rotate relative to the base 3. The C-shaped rotating bodies 6 in the two sets of rotating mechanisms 1 swing synchronously at the same time to achieve the purpose of driving the workpiece to rotate. During the movement of the C-shaped overturning body 6, the pressure rollers 13 in the six anti-overturning mechanisms press against the C-shaped edges 9 on both sides of the C-shaped overturning body 6 to prevent it from overturning; while the guide rollers 14 in the six anti-overturning mechanisms can limit the horizontal position of the C-shaped overturning body 6. When it is necessary to drive the base 3 in the sliding and flipping mechanism 2 to move, the control system sends a signal to the sliding motor. The sliding motor drives the base 3 to move relative to the bottom support plate 16 through gear and rack transmission (the base 3 slides on the sliding rail 15). The limit blocks 27 set at both ends of the bottom support plate 16 restrict the extreme movement position of the base 3 and can prevent the base 3 from falling off the sliding rail 15.
