Slender axle multi-station different drilling fixture

Abstract

The invention relates to a slender axle multi-station different drilling fixture which comprises a base plate, a pivoting support and a numerical control dividing plate, wherein the pivoting support and the numerical control dividing plate are installed on both sides of the base plate and have the same central axis; a positioning column and a connecting piece are arranged on the base plate; a first connecting disc with a pivoting shaft is installed on the pivoting support through a bearing, a second connecting disc is installed on the inner side surface of the numerical control dividing plate, and the lower parts of the first connecting disc and the second connecting disc are connected through a connecting plate; at least two V-shaped positioning and clamping assemblies which are used for radially positioning and clamping a slender axle workpiece are installed on the connecting plate and can be moved on the connecting plate in the horizontal direction; and a positioning assembly which is used for axially positioning a clamping ring groove of the slender axle workpiece is installed on the connecting plate, or a positioning assembly which is used for axially positioning the end surface of the slender axle workpiece is installed on the second connecting disc. The slender axle multi-station different drilling fixture has the advantage of compact and reasonable structure and can be used for processing multiple kinds of slender axle workpieces, the fixture replacement is reduced, and the processing precision and the processing efficiency of the slender axle workpieces can be increased.

Description

technical field [0001] The invention relates to a slender shaft multi-station different-direction drilling jig, which belongs to the technical field of shaft processing. Background technique [0002] For drilling and reaming and step surface processing of slender shaft workpieces with an aspect ratio greater than 10, V-shaped positioning blocks are usually used to clamp and position the slender shaft workpieces, especially when the holes to be processed on the shaft are in different directions. At the same time, it is also necessary to use the indexing plate to control the angle of the workpiece, so when rotating the slender shaft workpiece, it is necessary to loosen the clamping positioning mechanism first, and then re-clamp the slender shaft workpiece after the slender shaft workpiece is rotated in place position. Therefore, in the multi-station different-direction machining of the slender shaft workpiece, it is necessary to adopt multiple clamping and positioning, which ...

Problems solved by technology

Furthermore, the diameters and lengths of the slender shaft workpieces of each structure are different, the distance between the different-direction holes and the different-direction angles are all different, so a set of Fixtures not only increase the production cost of tooling, but also need to replace the corresponding drilling fixtures on the workbench when processing slender shaft workpieces with different structures, which is complicated to operate and increases the labor intensity of operators, which is time-consuming and laborious
