Locking device for rotary radial drilling fixture for disc parts

Abstract

The invention relates to a locking device for a rotary radial drilling fixture for disc parts. The locking device comprises an index plate and four tighteners, each tightener is located on the index plate, the four tighteners are arranged radially along a central axis of the index plate, the index plate is composed of an end cap and a housing, the end cap is of a disc-shaped structure, four sector grooves are uniformly formed in the end cap and arranged circularly along the central axis of the index plate, a through hole is arranged between every two adjacent sector grooves, an internal thread is arranged on the inner wall of each through hole, thirty six alignment holes are arranged in the front end of the housing uniformly, each alignment hole is of a semicircular structure, the thirty six alignment holes are arranged circularly along the central axis of the housing, scale marks are arranged on the outer wall of the housing uniformly, and a scale value between every two adjacent scale marks is two degrees. The locking device can lock, fix and accurately position the disc parts during radial drilling, and accuracy and quality of radial drilling of the disc parts are improved.

Description

technical field [0001] The invention relates to the field of drilling jigs, in particular to a locking device for radial drilling jigs of rotary disk parts. Background technique [0002] A fixture is a device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to accept construction or testing. In a broad sense, it is used for quick, convenient and safe installation in any process in the process. Workpiece devices can be called fixtures; such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common. The technical requirements such as shape and mutual position accuracy with other surfaces, the workpiece must be installed and clamped firmly before processing; the fixture is usually composed of positioning elements (determining the correct position of the workpiece in the fixture), clamping devices, and tool setting guide elemen...

AI Technical Summary

Problems solved by technology

[0003] The drilling jig belongs to one of the jigs. The drilling jig is mainly used to provide convenience for drilling the workpiece and facilitate the drilling work. According to the different shapes of the drilling workpiece, the design of the drilling jig is also different. However, at present Most of the drilling jigs are flat drilling jigs, and there are very few curved surface drilling jigs. Because the curved surface has problems such as poor fixation and easy slippage, it brings great difficulty to the curved surface drilling; in view of this, the present invention provides a Locking device for radial drilling jig of rotary disc parts
