Multi-workpiece drilling equipment with movable fixture

Abstract

The invention discloses multi-workpiece drilling equipment with a movable fixture, and belongs to the technical field of machining equipment. The multi-workpiece drilling equipment comprises a framework and the fixture. The fixture is positioned on the framework; a drill bit is arranged on the upper side of the framework and corresponds to the fixture; a slide table is further arranged on the framework, and slide rails are arranged on the surface of the slide table; the fixture comprises a fixture bottom plate, a positioning block, a clamping block and a clamping block driving device, the positioning block and the clamping block are positioned on the fixture bottom plate and are opposite to each other, and the clamping block driving device can drive the clamping block to slide towards the positioning block; a return spring is arranged between the positioning block and the clamping block in a connected manner; V-shaped grooves which correspond to one another are formed in opposite surfaces of the positioning block and the clamping block; the clamping block driving device comprises a cylinder and a wedge block, the wedge block is connected with a piston rod of the cylinder, and an oblique plane is arranged on the surface, which is opposite to the corresponding V-shaped grooves, of the clamping block and is matched with an oblique plane of the wedge block; rollers are arranged and supported on the oblique plane of the clamping block, and the oblique plane of the wedge block is tangential to the surfaces of the rollers. The multi-workpiece drilling equipment has the advantages that the machining efficiency can be improved, self-locking effects can be realized after workpieces are clamped, the multi-workpiece drilling equipment can be automatically reset after the workpieces are completely machined, and drilling procedures can be reliably and accurately carried out.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a clamp-shifting multi-workpiece drilling equipment. 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 fixture shifting multi-w...
