Abstract

The invention discloses an automatic fixture for a numerically controlled milling machine, which comprises a base, a fixed seat, a movable seat and a clamping device. The seat is located on the upper surface of the base, the movable seat is movably connected with the base, the bottom of the movable seat is provided with a dovetail groove, the bottom of the movable seat is provided with a bump, the fixed seat is fixedly connected to the right end of the base, and the movable seat A clamping device is provided between the fixed seat and the clamping device includes a connecting seat and a splint, the connecting seat is fixedly connected with the splint, and a hydraulic cylinder is provided at the left end of the base, and the hydraulic cylinder is fixedly connected with the base. By providing a replaceable clamping block in the jaws, it is convenient to replace clamping blocks of different shapes to improve the versatility of the fixture. By providing a hydraulic push device, it is more convenient and simple to clamp the workpiece, reducing the cost of technical learning, and The strong clamping force makes the workpiece processing more stable and improves the processing efficiency.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to an automatic fixture for a numerically controlled milling machine. Background technique [0002] In modern production, machine tool fixtures are an indispensable process equipment, which directly affects machining accuracy, labor productivity and product manufacturing costs, so machine tool fixtures occupy an extremely important position in enterprise production. However, in the prior art, on the CNC milling machine or machining center, the clamping object of the fixture is single, the clamping block cannot be replaced, and the square part is clamped with the flat pliers, or the rotary part is clamped with the three-jaw chuck. It is long, and it is very inconvenient to replace the clamping block, which leads to low production efficiency and is difficult to meet the needs of modern production. Contents of the invention [0003] The purpose of the present invention is to provide a kind o...
