Problems solved by technology

[0002] At present, in the manufacturing process of rotary joints and other parts, the end face hole processing of disc parts is usually completed by drilling equipment. The fixture on the existing drilling equipment cannot self-lock after clamping, and the workpiece is easy to loose when the force is large. Moreover, most of them are single-piece clamping. In batch processing, the number of loading and unloading is too many and the operation is troublesome, which cannot meet the needs of multiple clamping, resulting in low processing efficiency, and the cumulative error caused by multiple clampings affects the processing quality of workpieces.

Abstract

The invention belongs to the technical field of machining equipment and discloses a self-locking drilling fixture comprising a bottom plate, a positioning block, a clamping block and a driving device. The positioning block and the clamping block are disposed on the bottom plate face to face; the driving device drives the clamping block to slide to the positioning block; the positioning block is fixed; opposing faces of the positioning block and the clamping block are provided with at least two V-grooves facing each other; the driving device comprises a cylinder and a wedge connected to a piston rod of the cylinder; a sliding direction of the wedge is perpendicular to that of the clamping block; the surface, corresponding to one V-groove, of the wedge is a slope fitly attaching to a slope of the wedge. The self-locking drilling fixture has the advantages that manual frequent changing of workpieces is avoided, machining efficiency is improved, self-locking after clamping is available, and a drilling process is more reliable and accurate.

Description

technical field [0001] The invention relates to the technical field of machining equipment, in particular to a self-locking drilling jig. Background technique [0002] At present, in the manufacturing process of rotary joints and other parts, the end face hole processing of disc parts is usually completed by drilling equipment. The fixture on the existing drilling equipment cannot self-lock after clamping, and the workpiece is easy to loose when the force is large. Moreover, most of them are single-piece clamping. In batch processing, the number of loading and unloading is too many and the operation is troublesome, which cannot meet the needs of multiple clamping, resulting in low processing efficiency, and the cumulative error caused by multiple clampings affects the processing quality of workpieces. Contents of the invention [0003] The object of the present invention is to provide an efficient multi-workpiece self-locking drilling jig to solve the above problems. [0...
