Description

Technical Field

[0001] This invention relates to the field of automotive testing technology, specifically to a flexible positioning platform for four doors and two hoods of an automobile. Background Technology

[0002] With the continuous development of the automotive industry, the market demands higher and higher quality from automobiles. During automobile production, doors and hoods generally require various inspections before assembly, including checks on their appearance, dimensions, structure, and color, typically using scanners, vision cameras, and coordinate measuring machines. However, the shapes and specifications of doors and hoods vary across different car models. Due to their weight, manual operation is time-consuming, labor-intensive, inefficient, prone to errors, and lacks measurement accuracy. Traditional measuring fixtures, due to their unique correspondence with each workpiece, often require numerous different types of fixtures for a single car model, necessitating frequent disassembly and reassembly, and consuming significant storage space. Furthermore, the cost of fixtures for each car model is high, leading to high inspection costs, and the lack of versatility results in substantial waste. In the existing technology, a multi-axis robotic arm has been used for positioning and fixing, thereby enabling flexible adjustment according to the shape and size of different car models. Although the robotic arm is highly flexible, due to the low strength of the multi-axis robotic arm and the relatively heavy weight of the car door and hood, it is prone to loosening, shaking and other unstable positioning, which affects the accuracy of the detection.

[0017] Reference Figures 1-6 An embodiment of the present invention provides a flexible positioning platform for four doors and two hoods of an automobile, comprising: a base 1, side supports 2 symmetrically arranged on both sides of the base 1, a flipping platform 3 rotatably connected between the two side supports 2 and driven by a motor, a plurality of positioning support fixtures 4 connected above the flipping platform 3 by a supporting three-axis servo mechanism, and at least two positioning clamping fixtures 5 connected above the base 1 by a clamping three-axis servo mechanism, wherein the positioning clamping fixtures 5 are located in front of the flipping platform 3.

[0018] In the above technical solution, a flipping platform 3 is rotatably connected between the side supports 2 on both sides of the base 1 and driven by a motor. Multiple positioning support fixtures 4 are connected to the flipping platform 3 via a three-axis servo mechanism. The base 1 is located in front of the flipping platform 3 and is connected to at least two positioning clamping fixtures 5 via a clamping three-axis servo mechanism. By switching the state of the flipping platform 3, the present invention can be used for positioning and fixing of car doors or car covers for testing. For example, when it is necessary to position and fix the car cover, the flipping platform 3 is rotated to a horizontal state, and the car cover can be placed on the positioning support fixtures 4 on the flipping platform 3 for positioning and fixing. When it is necessary to position and fix the car door, the flipping platform 3 is rotated to a vertical state, and the bottom of the car door is clamped and fixed to the positioning clamping fixtures 5 on the base 1. At the same time, the positioning support fixtures 4 of the flipping platform 3 are used to further position and fix the side of the car door, thus completing the positioning and fixing of the car door. The flipping platform 3 can also be flexibly rotated and adjusted according to the needs of other positioning angles. Both the positioning support fixture 4 and the positioning clamping fixture 5 adopt an adjustable connection method of three-axis servo mechanism, which can flexibly adjust the position according to the workpiece to be inspected with different sizes and shapes, meet the positioning requirements of doors and hoods of different car models, have high versatility, and the structure of the three-axis servo mechanism is more stable than that of the robot arm, so that the workpiece is positioned stably and the inspection is accurate.

[0019] In some embodiments, the supporting three-axis servo mechanism includes: a first sliding seat 6, a second sliding seat 7, and a third sliding seat 8. The first sliding seat 6 is slidably connected above the tilting platform 3 and driven by a servo motor via a lead screw. The second sliding seat 7 is slidably connected above the first sliding seat 6 and driven by a servo motor via a lead screw. The third sliding seat 8 is slidably connected to the second sliding seat 7 and driven by a servo motor via a lead screw. The positioning support fixture 4 is fixed to the third sliding seat 8. The sliding directions of the first sliding seat 6, the second sliding seat 7, and the third sliding seat 8 are mutually perpendicular, and the sliding direction of the third sliding seat 8 is perpendicular to the tilting platform 3. This structural design allows for flexible adjustment of the position of the positioning support fixture 4, and ensures a stable and secure fixation. The positioning support fixture 4 is less prone to loosening or shaking, thus ensuring accurate detection.

[0020] In some embodiments, the clamping three-axis servo mechanism includes: a fourth sliding seat 9, a fifth sliding seat 10, and a sixth sliding seat 11. The fourth sliding seat 9 is slidably connected above the base 1 and driven by a servo motor via a lead screw. The fifth sliding seat 10 is slidably connected above the fourth sliding seat 9 and driven by a servo motor via a lead screw. The sixth sliding seat 11 is slidably connected above the fifth sliding seat 10 and driven by a servo motor via a lead screw. The positioning clamping fixture 5 is fixed above the sixth sliding seat 11. The sliding directions of the fourth sliding seat 9, the fifth sliding seat 10, and the sixth sliding seat 11 are mutually perpendicular, and the sliding direction of the sixth sliding seat 11 is perpendicular to the base 1. This structural design allows for flexible adjustment of the position of the positioning clamping fixture 5, and ensures a stable fixation. The positioning clamping fixture 5 is less prone to loosening or shaking, guaranteeing accurate detection.

[0021] In some embodiments, the positioning support fixture 4 includes a positioning support base 401 and a positioning support ball head 402. The positioning support base 401 is fixed above the third sliding seat 8, and at least one positioning support ball head 402 is fixed on the positioning support base 401. In practical applications, each positioning support base 401 can be equipped with a different number of positioning support ball heads 402 as needed.

[0022] Furthermore, the positioning support ball head 402 is a magnetic ball head. Specifically, a permanent magnet can be used to conduct magnets onto the ball head, which can effectively improve the positioning stability of the workpiece. In other embodiments, the positioning support ball head 402 can adopt an electromagnet structure. Using an electromagnet in the positioning support ball head 402 not only improves the positioning stability of the workpiece but also facilitates the installation and disassembly of the workpiece during positioning. Only the on / off state of the electromagnet needs to be controlled, eliminating the need for manual positioning and fixing.

[0023] Furthermore, the positioning support base 401 is equipped with a suction cup 403 at each of the positioning support ball heads 402, and the suction cup 403 is flush with the positioning support ball head 402. Specifically, the suction cup 403 is connected to a vacuum device via a pipe. The suction cup 403 not only further improves the positioning stability of the workpiece, but also facilitates the installation and removal of the workpiece during positioning, as only the power to the vacuum device needs to be controlled, eliminating the need for manual positioning and fixing.

[0024] In some embodiments, the positioning and clamping fixture 5 includes: a clamping support 501, a positioning and clamping ball head 502, and an elbow clamp 503. The clamping support 501 is fixed above the sixth sliding seat 11. The positioning and clamping ball head 502 is horizontally fixed on one upper side of the clamping support 501, and the elbow clamp 503 is fixed on the other upper side of the clamping support 501. The positioning and clamping ball head 502 and the elbow clamp 503 are opposite each other and used to clamp the workpiece. The elbow clamp 503 can be a commercially available elbow clamp. The mating structure of the positioning and clamping ball head 502 and the elbow clamp 503 can quickly and securely clamp and fix the workpiece.

[0025] In some other embodiments, the positioning clamping ball head 502 can be fixed to the upper side of the clamping support 501 by a threaded rod. This structural design allows the threaded rod to adjust the distance between the positioning clamping ball head 502 and the elbow clamp 503, thus making it suitable for workpieces of different thicknesses and highly versatile.

[0026] In some embodiments, a groove 5011 is provided above the clamping support 501. The structural design of the groove 5011 allows the workpiece to be supported more quickly and stably above the clamping support 501.

[0027] In some embodiments, the base 1 is provided with a slide rail or groove 12 located below the flipping platform 3. The slide rail or groove 12 can be used to mount the robotic arm of the scanning ball head, thereby enabling more flexible scanning and detection.
