Description

Technical Field

[0001] The utility model relates to the technical field of turning, and specifically relates to a turning fixed tooling fixture. Background Art

[0002] Turning is a machining method that uses a cutting tool on a rotating machine to remove metal materials. In the metal forming process, turning is mainly used to remove excess material to produce parts with complex shapes and precise dimensions. Turning has a wide range of applications, including automobile manufacturing, machinery manufacturing, tool manufacturing, electronic equipment manufacturing and other fields.

[0003] In order to ensure stability during machining, the workpiece needs to be fixed on the worktable of the machine tool during turning. This can prevent the workpiece from moving or tilting under the action of cutting force, thereby maintaining machining accuracy. If the fixing effect is not good, movement or tilting may occur during machining, resulting in reduced machining accuracy, and excess material may be cut off by the cutting tool during cutting, resulting in waste. Therefore, we propose a turning fixed fixture. Utility Model Content

[0010] Preferably, a base is fixedly connected to the lower surface of the bottom plate, and pads are symmetrically arranged on the lower surface of the base.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: when performing turning work, a sliding support table is pre-set, and the workpiece can be conveniently arranged for cutting again through the sliding of the processing. The design of the support table away from the cutting head allows the operator to stay away from the dangerous area, thereby improving the operating safety. At the same time, an electromagnet is arranged at the center of the support table. The use of the electromagnet allows the workpiece to be conveniently adsorbed and released, reducing errors and dangers during operation. Clamping structures are arranged on both sides, and the clamping structure is driven by hydraulics. In addition, the hydraulically driven clamping can provide greater clamping force. Protrusions are arranged on both sides of the convex clamping plate, and the protrusions are semicircular, which can better clamp the workpiece and realize double-station four-point clamping. Through the cooperation of the electromagnet and the clamping structure, the workpiece is prevented from moving or tilting under the action of the cutting force, thereby maintaining the processing accuracy, ensuring that the cutting tool and the workpiece maintain a consistent relative position, improving the cutting efficiency, and preventing the workpiece from splashing or falling off during the processing, thereby reducing the risk of injury to the operator.
