Abstract

The invention discloses a slender axle drilling clamp. The invention overcomes the defects of larger pitch change between adjacent holes and scrap iron splashing and hurting people of the present slender axle adopting a baffle for positioning. The slender axle drilling clamp comprises a base and a pressing block, wherein two first thread blind holes and a second thread blind hole are arranged in the upper part of the base; a V-shaped slot is arranged on the upper part of the base; a positioning block is arranged on the side wall of the base; a thread through hole is arranged in the positioning block; a positioning bolt is arranged in the thread through hole; a reverse V-shaped slot corresponding to the V-shaped slot is arranged at the bottom of the pressing block; friction plates are arranged on two side walls of the reverse V-shaped slot; two counter bores are arranged in the pressing block; hexagon socket screws are arranged in the counter bores; the hexagon socket screws are in threaded connection with the base; a guiding hole is arranged in the pressing block; a guiding pillar is arranged in the guiding hole; the guiding pillar is in threaded connection with the second thread blind hole; a magnet and a supporting plate are arranged on the side wall of the pressing block; a guiding sleeve is arranged on the supporting plate; the magnet is located under the guiding sleeve.

Description

technical field [0001] The invention belongs to the field of drilling jigs for shafts, in particular to a drilling jig for slender shafts. Background technique [0002] Shafts whose length-to-diameter ratio is greater than 25 (ie L / D>25) are called slender shafts. Such as a diesel engine tie rod, its length is about 2m ~ 3m, and the outer diameter is about φ20mm ~ φ30mm. Due to the poor rigidity of the slender shaft, it is easily deformed by the cutting force and vibration during turning, and processing errors such as straightness and cylindricity occur, and it is difficult to meet the technical requirements of shape and position accuracy and surface quality on the pattern. Machining is difficult. The larger the L / d value, the more difficult the turning process. [0003] Usually, the slender shaft is positioned by a pressing plate when drilling, and the pressing plate compresses the slender shaft, and the pressing plate is connected with the drilling machine workbench ...
