Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically to a tooling for laser marking on automotive rear control arms. Background Technology

[0002] Laser marking technology is mainly used for permanent identification in rear swing arm processing. It enables precise marking of information such as QR codes, serial numbers, and production dates, meeting traceability and anti-counterfeiting requirements. This technology is applicable to fields such as automotive parts and machinery manufacturing. Its non-contact processing characteristics are particularly suitable for surface treatment of metal or alloy materials, avoiding deformation or wear caused by traditional mechanical marking.

[0003] The core structure of laser marking fixtures includes a laser generator, a galvanometer system, and fixtures. Among these, the fixtures are a crucial component of the marking process. Existing solutions typically consider the shape and size of a single workpiece, designing separate fixtures for the left and right sides to achieve customized positioning and clamping, effectively fixing the workpiece, preventing displacement, ensuring precise and repeatable positioning, and improving marking accuracy. Traditional fixture designs often require line changes for different models / left / right rear swing arms, necessitating fixture replacements and increased debugging time (exceeding 30 minutes), thus reducing overall equipment efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a tooling for laser marking on the rear swing arm of an automobile.

[0006] The upper end face of the fixture base plate is provided with six initial limiting devices at the left and right ends respectively, and two rows of initial limiting devices are provided at the left and right ends respectively, with the two rows of initial limiting devices being symmetrical to each other.

[0007] Two longitudinally arranged component positioning sensors are respectively set in the center of the two rows of initial limiting devices at the left and right ends of the upper surface of the fixture base plate. A B-type positioning support and an A-type positioning support are respectively set at the left and right ends of the component positioning sensor at the front left side. A second B-type positioning support is set on the right side of the component positioning sensor at the front right side. Two B-type positioning supports are respectively set at the left and right ends of the component positioning sensors at the rear left and right sides.

[0008] A left-right judgment laser sensor is provided on the left side of the front end of the fixture base plate, and another left-right judgment laser sensor is provided in the middle section of the front end of the fixture base plate.

[0009] Handles are provided on the upper left side and lower right side of the upper surface of the fixture base plate, and lifting rings are provided on the upper right side and lower left side of the upper surface of the fixture base plate.

[0010] The advantages of this utility model are that this tooling has the functions of fixing the workpiece, preventing displacement, ensuring accurate positioning and repeatability of the workpiece, and improving marking accuracy, while also being able to adapt to the left / right rear swing arm. It can automatically identify the left and right workpieces without switching the tooling hardware, ensuring that it can produce two sets of left, two sets of right, or one left and one right workpiece, which greatly improves the convenience of production and greatly improves the overall utilization rate of the equipment when the left and right materials are not completely matched.
