Description

Technical Field

[0001] The utility model relates to the technical field of milling machine processing fixtures, in particular to a fast positioning milling machine processing fixture. Background Art

[0002] Milling machine is a widely used machine tool. It can process planes (horizontal plane, vertical plane), grooves (keyways, T-slots, dovetail grooves, etc.), toothed parts (gears, spline shafts, sprockets), spiral surfaces (threads, spiral grooves) and various curved surfaces.

[0003] However, when processing metal plates, the existing milling machines are unable to fix and clamp metal plates of different shapes, and after the metal plates are placed, the positions of the metal plates need to be manually corrected, which is very inconvenient to use.

[0004] For example, a fast positioning milling machine processing fixture disclosed in Chinese patent CN217453030U can make the limit plate drive the auxiliary rod fixedly connected to its side to slide and adjust inside the adjustment hole by pulling the limit plate, so that the auxiliary rod drives the clamping plate fixedly connected to its other end to adjust the position inside the processing groove. The top protective plate and the connecting rod of the foldable rubber plate can make the top protective plate move synchronously with the clamping plate, and at the same time, the compression spring fixedly connected to its side can be driven to contract as the clamping plate moves and adjusts, thereby realizing the movement of the clamping plate. With the assistance of the hardware, the metal plate is then placed on the lower surface of the inner cavity of the processing groove, and then the pulling force on the limit plate is reduced at a uniform speed. When the pulling force on the limit plate is less than the force of the compression spring itself, the compression spring is reset by its own force, and then the clamp is reset, so that the clamp and the outer side of the metal plate are installed in coordination, thereby realizing the rapid positioning and fixed clamping of the metal plate, and then the dust removal fan is operated through the single-chip microcomputer, so that the dust removal fan removes the dust inside the processing groove through the dust removal hole, thereby completing the auxiliary work of the rapid positioning milling machine processing fixture.
