Description

Technical Field

[0001] The utility model relates to the technical field of cable bridge processing, in particular to a cable bridge processing positioning fixture. Background Art

[0002] In the process of cable tray processing, accurate size cutting is the key link to ensure the quality and installation accuracy of cable tray. However, there are some problems with the existing cable tray processing positioning fixture:

[0003] 1. Traditional positioning fixtures can only simply fix the plates and cannot achieve precise horizontal and vertical positioning. This makes it easy for the plates to shift during the cutting process, resulting in inaccurate cutting dimensions and affecting the assembly and use of the cable tray.

[0004] 2. Some fixtures rely on manual measurement and adjustment when positioning the plate, which is not only inefficient but also prone to human errors. For example, when using a ruler for measurement, inaccurate readings or improper measurement positions may cause large deviations in the cutting size of the plate.

[0005] 3. After some clamps clamp the plate, it is not convenient to observe the cutting position and progress, which makes it difficult for operators to accurately grasp the cutting situation during the cutting process, which may lead to over-cutting or under-cutting problems.

[0006] Therefore, those skilled in the art provide a cable tray processing and positioning fixture to solve the problems raised in the above background technology. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] Accurate horizontal positioning: The motor drives the gear transmission system to move rack 1 and rack 2, thereby driving the positioning plate to push the plate. The positioning plate is in contact with the plate during the pushing process, which can achieve accurate horizontal positioning. This positioning method is not limited by the size and shape of the plate, and can ensure that plates of different specifications can be accurately positioned on the workbench, providing a reliable foundation for subsequent cutting operations;

[0018] Stable vertical positioning: Cylinder 1 and Cylinder 2 drive Platen 1 and Platen 2 to press down and fix the plate on the workbench. This vertical positioning method can effectively prevent the plate from shifting up and down during the cutting process, ensuring the flatness and verticality of the cutting surface, and can adapt to plates of different thicknesses and sizes by adjusting the stroke of the cylinder;

[0019] Automatic positioning: The gear transmission system driven by the motor realizes the automatic horizontal positioning of the plate. The operator only needs to put the plate on the workbench and start the motor to complete the positioning operation, which greatly reduces the time of manual measurement and adjustment and improves the processing efficiency.
