Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production, and particularly relates to an anti-error automatic recognition fixture. Background Technique

[0002] Automobile parts, as the foundation of the automobile industry, are necessary factors to support the sustainable and healthy development of the automobile industry. Especially the current independent development and innovation in full swing in the automobile industry require a strong parts system as support.

[0003] For example, the sheet metal parts of automobile parts are core components of the automobile. However, during the stamping process of the sheet metal parts of automobile parts, holes are punched at the designed positions. Then, an operator places nuts at the hole positions of the sheet metal parts of the automobile parts, and then an intelligent robot clamps and moves the sheet metal parts of the automobile parts to the welding and assembly equipment.

[0004] However, due to the small size of the hole positions and nut positions, it is very difficult for the operator to visually identify whether the nuts are placed. Once the nuts are not installed, it will cause greater cost losses, and the subsequent troubleshooting will become extremely cumbersome, and it will cause a great waste of manpower and material resources. Content of the Utility Model

[0005] The utility model aims to provide an anti-error automatic recognition fixture, which can automatically identify whether nuts are installed at the hole positions of the sheet metal parts of automobile parts.

[0006] To achieve the above object, each aspect of the present application can be implemented in one or more of the following embodiments:

[0007] 1) An anti-error automatic recognition fixture, including a first side clamp and a second side clamp, the first side clamp and the second side clamp are respectively located on both sides of the sheet metal part of the automobile part and clamp it. The first side clamp includes a first clamp seat and a first flap. The upper surface of the first clamp seat is used to place the sheet metal part of the automobile part. The end of the first clamp seat is rotatably connected to the end of the first flap. A first driving mechanism for driving the first flap to rotate is provided on the first flap. The first driving mechanism drives the first flap to rotate towards the first clamp seat direction and clamps the sheet metal part of the automobile part.

[0008] The second side clamp includes a second clamp seat and a second flap. The upper surface of the second clamp seat is used for placing the sheet metal part of the automotive component. The end of the second clamp seat is rotatably connected to the end of the second flap. A distance sensor for detecting the position of the nut of the sheet metal part of the automotive component is provided on the second clamp seat. A second driving mechanism for driving the second flap to rotate is provided on the second flap. The second driving mechanism drives the second flap to rotate towards the second clamp seat and clamp the sheet metal part of the automotive component; a microprocessor is further included, and the microprocessor is electrically connected to the first driving mechanism, the distance sensor and the second driving mechanism respectively.

[0009] During use, after the operator places the nut in the hole position of the sheet metal part of the automotive component, the distance sensor detects whether there is a nut in the hole position, and the distance sensor sends the detected hole position distance value to the microprocessor. The preset value in the microprocessor is the distance value with a nut. When the preset value in the microprocessor is less than the hole position distance value, it is determined that there is a nut in the hole position, and the microprocessor issues an instruction to start the second driving mechanism to drive the second flap to rotate towards the second clamp seat and clamp the side part of the sheet metal part of the automotive component.

[0010] Then, the microprocessor issues an instruction to start the first driving mechanism to drive the first flap to rotate towards the first clamp seat and clamp the other side part of the sheet metal part of the automotive component, so as to stably operate the sheet metal part of the automotive component; on the contrary, the first driving mechanism and the second driving mechanism will not start. When the first driving mechanism and the second driving mechanism do not start, the operator can know that there is no nut in the hole position of the sheet metal part of the automotive component, which can prompt the operator to place the nut in the hole position of the sheet metal part of the automotive component.

[0041] Through three hinged ways, when the first telescopic cylinder 5 receives an instruction from the microprocessor, it drives the first telescopic rod to extend along the height direction. Under the movement of the first telescopic rod, it drives the end of the first flap 4 to rotate around the first clamping seat 2, the first support rod to flip around the first telescopic rod, and the first telescopic cylinder 5 to rotate outward around the first clamping seat 2, so as to realize the movement of the first flap 4 towards the first clamping seat 2, and thus realize the clamping of the side part of the sheet metal part of the automotive component.

[0046] Through three hinged ways, under the instruction of the microprocessor, the second telescopic cylinder 12 drives the second telescopic rod to extend along the height direction. Under the movement of the second telescopic rod, it drives the end of the second flap 11 to rotate around the second clamping seat 3, the second support rod to flip around the second telescopic rod, and the second telescopic cylinder 12 to rotate outward around the second clamping seat 3, so as to realize the movement of the second flap 11 towards the second clamping seat 3, and thus realize the clamping of the other side part of the sheet metal part of the automotive component.

[0049] During use, after the operator places a nut in the hole position of the sheet metal part of the automotive component, the distance sensor 14 detects whether there is a nut in the hole position. The distance sensor 14 sends the detected hole position distance value to the microprocessor. The preset value in the microprocessor is the distance value with a nut. When the preset value in the microprocessor is less than the hole position distance value, it is judged that there is a nut in the hole position. The microprocessor will issue an instruction to start the second driving mechanism to drive the second flap 11 to rotate towards the second clamping seat 3 and clamp the side part of the sheet metal part of the automotive component.

[0050] Then, the microprocessor issues an instruction to start the first driving mechanism to drive the first flap 4 to rotate towards the first clamping seat 2 and clamp the other side part of the sheet metal part of the automotive component, so as to stably operate the sheet metal part of the automotive component; conversely, the first driving mechanism and the second driving mechanism will not start.
