Self-resetting drilling fixture

Abstract

The invention belongs to the technical field of machining equipment and discloses a self-resetting 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; a reset spring is connected between the positioning block and the clamping block; 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 certain V-grooves, of the wedge is a slope matching with a slope of the wedge; rollers are arranged and supported on the slope of the clamping block; the slope of the wedge is tangent to the surfaces of the rollers. The self-resetting drilling fixture has the advantages that machining efficiency is improved, self-locking after clamping is available, self-resetting after completion 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-resetting 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-resetting drilling jig to solve the above problems. ...
