Description

Technical Field

[0001] The utility model relates to the technical field of aluminum processing, in particular to a positioning and marking mechanism for aluminum profile bending parts. Background Art

[0002] The main function of the positioning and marking mechanism for aluminum profile bending parts is to ensure the accurate positioning and marking of materials before bending during the processing of aluminum profiles. The application of this mechanism can significantly improve the automation level of aluminum profile processing, reduce the need for manual operation, and at the same time ensure the repeatability of the processing process and the quality consistency of products.

[0003] After retrieval, a positioning and marking mechanism for aluminum profile bending parts with the publication number CN214442141U includes a clamping fixture for clamping and fixing the profile to be detected. Drawing tools are respectively and fixedly installed on the clamping fixtures at both ends of the profile along the length direction. The drawing tool includes a mounting seat that is convenient for installation and fixation on the clamping fixture and a rotating bent arm hinged on the mounting seat. A groove is opened at the upper end of the mounting seat, and the rotating bent arm is rotationally connected with the mounting seat through a penetrating rotating shaft. The rotating bent arm is L-shaped, and a fastening piece adapted to the mounting seat is fixedly installed on the rotating bent arm. After the rotating bent arm is flipped, it is fixedly installed in the groove of the mounting seat through the fastening piece. In this positioning and marking mechanism, after the rotating bent arm is flipped, sawing and marking and marking with a marking needle can be directly carried out, avoiding the problems of slow and inaccurate marking with a right-angle ruler and a measuring ruler. The operation is simple and fast, greatly improving the production capacity.

[0004] Based on the above patent, by directly drawing marking lines and sawing lines, it replaces the marking form using fixtures, right-angle rulers, marking needles, black marker pens, and scales. It realizes rapid marking, replaces the marking mode of right-angle rulers and scales, saves working time, avoids repeated positioning and marking, improves marking accuracy, can realize rapid three-sided marking with a marking needle and sawing marking, replaces the complex operations of right-angle rulers and measuring rulers, the marking is accurate and the operation is simple, reduces the production beat, saves production costs, and improves production capacity. However, when the rotating bent arm in this patent bends the aluminum profile, due to the limited bending amplitude of the rotating bent arm for the aluminum profile, the bending effect of the device on the aluminum profile becomes poor. Inaccurate bending will lead to material waste and an increase in the rework rate. Each rework not only consumes additional materials but also requires additional labor and machine time, which directly increases the production cost. Summary of the Utility Model

The connecting frame 2 can stably support the support rod 1 so that the equipment at the processing table 3 can be processed. When the driving motor 4 is started, the rotating plate 5 rotates, causing the rotating plate 5 to drive the fixed column 7, and the first connecting plate 11 to drive the second connecting plate 12 to move along the chute plate 13.

[0026] Specifically, a plurality of fixed columns 7 are fixedly connected to the top end of the rotating plate 5, the outer walls of the fixed columns 7 are rotatably connected to the first connecting plates 11, the rear ends of the first connecting plates 11 are rotatably connected to the second connecting plates 12, the bottom ends of the second connecting plates 12 are slidably connected to the chute plates 13, the bottom ends of the right first transfer shaft 9 and the left second transfer shaft 10 are rotatably connected to the transfer rods 14, the bottom ends of the transfer rods 14 are slidably connected to the sliding rods 15, the bottom ends of the chute plates 13 are fixedly connected to the top end of the processing table 3, and the top sides at the rear ends of the chute plates 13 are rotatably connected to the bottom ends of the bending frames 8. The connecting frame 2 can stably support the support rod 1 so that the equipment at the processing table 3 can be processed. When the driving motor 4 is started, the rotating plate 5 rotates, causing the rotating plate 5 to drive the fixed column 7, and the first connecting plate 11 to drive the second connecting plate 12 to move along the chute plate 13, so that the second connecting plate 12 pulls the bending frame 8 to deflect at an angle along the chute plate 13. The transfer rods 14 and the sliding rods 15 can facilitate the arc adjustment of the bending frame 8, thereby facilitating the arc adjustment between aluminum profiles, making the bending of aluminum profiles more accurate, ensuring that the dimensions and shapes of each component meet strict design standards, reducing the wear of the equipment caused by frequent adjustment and improper use, helping to maintain the good state of the equipment, extending the service life, and reducing the long-term maintenance and replacement costs.

[0028] Working principle: The connecting frame 2 can stably support the support rod 1 so that the equipment at the processing table 3 can be processed. Starting the drive motor 4 rotates the rotating plate 5, and the rotating plate 5 drives the fixed column 7, and the first connecting plate 11 drives the second connecting plate 12 to move along the chute plate 13, so that the second connecting plate 12 pulls the bending frame 8 to perform an angular offset along the chute plate 13. The adapter rod 14 and the sliding rod 15 can facilitate the arc adjustment of the bending frame 8, thereby facilitating the arc adjustment between aluminum profiles, making the bending of the aluminum profile more accurate, thus ensuring that the size and shape of each component meet strict design standards, reducing the wear of the equipment caused by frequent adjustment and improper use, helping to maintain the good state of the equipment, extending the service life, reducing the long-term maintenance and replacement costs. Rotating the one-way screw 16 moves the clamping plate 17 within the bending frame 8. Rotating the one-way screw 16 drives the two-way screw 18 to move the moving block 19, so that the moving block 19 drives the first support plate 20 to support the abutting plate 21 upward, fixing the aluminum profile at the clamping plate 17, improving the effect during the processing of the aluminum profile. A good fixing effect can ensure that the aluminum profile maintains a stable position and posture during the processing, prevent processing errors caused by movement or shaking, help improve the processing accuracy, and ensure that the product meets the design specification requirements.
