Description

Technical Field

[0002] Aluminum veneer refers to a building decoration material that is first processed by chroming and other treatments and then processed by fluorocarbon spraying technology. During the processing of the aluminum veneer, when punching the aluminum veneer, the aluminum veneer must be clamped and positioned. Therefore, a positioning fixture for punching aluminum veneers is required.

[0003] For this purpose, the Chinese patent with publication number CN218487785U discloses a positioning fixture for punching aluminum veneer, including a workbench, a longitudinal mounting frame, a transverse mounting frame and a clamping plate, the top surface of the workbench is symmetrically provided with a first guide slot on both sides, and a first threaded rod shaft is installed in the first guide slot, and one end of the first threaded rod shaft is connected to the output end of the first servo motor, the bottom surface of the longitudinal mounting frame is symmetrically welded with a first guide slider at both ends, and a first nut is fixedly installed in the first guide slider, and the first nut and the first threaded rod shaft are meshed with each other. Beneficial effect: The utility model is provided with a longitudinal mounting frame and a transverse mounting frame, and through the coordinated use of the longitudinal mounting frame and the transverse mounting frame, multiple punching positions on the aluminum veneer can be punched without loosening the clamping plate and the clamping plate, thereby greatly reducing the operation steps and workload of workers, which is conducive to improving the punching efficiency of the aluminum veneer.

[0004] However, in this patent, since the two side surfaces of the aluminum veneer are clamped and fixed by two clamping plates 7, and it is tightly abutted against the top of the aluminum veneer by two abutting plates 24, the other two side surfaces and the bottom of the aluminum veneer are still not clamped, which makes it not firmly clamped and fixed, which reduces its positioning effect. In addition, in this patent, since the thickness of the aluminum veneer is relatively thin and its bottom does not support the aluminum veneer, when the clamped aluminum veneer is punched, the aluminum veneer will be pressed downward and bent at the moment of punching, which will cause the punched area to break, easily causing damage to the aluminum veneer.
