A special fixture for drilling

Abstract

The invention discloses a special tool clamp for drilling. The special tool clamp comprises a clamp installing base, a second hydraulic telescopic rod, a stand column and a third hydraulic telescopic rod. A moving groove is formed in the clamp installing base. Installing through holes are formed in the clamp installing base. A first hydraulic telescopic rod is arranged in the moving groove. A moving cross frame is arranged at the left end of the first hydraulic telescopic rod. Compared with the prior art, the special tool clamp has the beneficial effects that the up-down and left-right movements of the clamp are achieved through the first hydraulic telescopic rod and the second hydraulic telescopic rod, and the problem that moving of a traditional fixed clamp is not convenient; a worker only needs to set a work program of the special tool clamp for drilling through a control cabinet, and then automatic drilling operation can be achieved; and manual operation of the worker is not needed, the labor intensity of the worker is relieved, and the danger of accidental injuries of the worker due to mistaken operation of the worker is reduced.

Description

technical field [0001] The invention belongs to the technical field of tooling fixtures, and in particular relates to a special tooling fixture for drilling. Background technique [0002] The device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to accept construction or inspection, also known as fixture. In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. When machining a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as the size, geometric shape, and position accuracy with other surfaces specified in the drawing, the workpiece must be installed and clamped before proce...
