Tool clamp and clamping method thereof

Abstract

The invention discloses a tool clamp and a clamping method thereof. The tool clamp comprises a fixing disc, a first columnar cavity with an upward opening is formed in the fixing disc, four hydraulic grooves are formed in the annular face of the first cavity at equal angles with the axis of the first cavity as the center, and hydraulic rods are slidably connected into the hydraulic grooves. A columnar workpiece and a rectangular workpiece can be clamped, the center of each workpiece can be fixed, and the operation step of setting the zero point of the X axis and the zero point of the Y axis before machining is omitted. In addition, the clamping force of clamping can be set, workpiece deformation or abrasion possibly caused by too large clamping force is prevented, and the situation that the machining precision becomes poor possibly caused by too small clamping force is also prevented. After machining is completed, the machining face of each workpiece can be cleaned, workers are prevented from making contact with cutting fluid during measurement, and cleaning water can be discharged and prevented from diluting the cutting fluid.

Description

technical field [0001] The invention relates to the technical field of tooling fixtures, in particular to a tooling fixture and a clamping method thereof. Background technique [0002] Fixture refers to the device used to clamp the workpiece, which can fix the workpiece to be processed on the machine tool and make it easy to process. [0003] For the cylindrical workpiece, if it is to be processed in the machining center, the fixing method is generally to use an electromagnetic suction plate or a splint. If this kind of fixing method is used, the X and Y of the workpiece must be set after each workpiece is replaced. The zero point of the axis, which increases the workload of the staff, and the machining center generally processes high-precision parts. After the roughing of the workpiece, the staff usually needs to measure the size, which makes the staff often contact with the cutting fluid, which will give Staff pose certain health risks.
