Adjustable shaft part drilling jig

Abstract

The invention discloses an adjustable shaft part drilling jig which comprises a base plate (1), a floating V-shaped block (2), a pressing V-shaped block (3) and a drilling jig plate (4), wherein the floating V-shaped block (2) and the drilling jig plate (4) are mounted close to left and right ends on the base plate (1), respectively; the floating V-shaped block (2) is capable of floating up and down and is locked by a fastening bolt (7) arranged on the end part of the base plate (1); a drilling jig hole (9) downward penetrating through a supporting hole (8) is formed in the top of the drilling jig plate (4); a drilling sleeve (14) is arranged at the opening of the drilling jig hole (9). The adjustable shaft part drilling jig is fit for clamping to-be-processed shafts in different diameters by adjusting the height of the floating V-shaped block; the axial lines of the to-be-processed shafts are kept horizontal; the floating V-shaped block and the pressing V-shaped block are used for supporting and pressing the processed shaft parts, so that the processed shaft parts are reliably mounted and pressed; the adjustable shaft part drilling jig has an excellent centering function and can guarantee the central positions of the shafts.

Description

technical field [0001] The invention relates to an adjustable shaft part drilling mold, which belongs to the technical field of mechanical processing auxiliary equipment. Background technique [0002] The holes perpendicular to the center line on both ends of the shaft parts are processed. In addition to the size requirements of the hole, the shape and position tolerance requires that the center of the hole and the center of the shaft have perpendicularity and symmetry requirements. [0003] In the actual processing process, since there is no corresponding drilling jig to fix the shaft parts to be processed well, only a simple pressing plate or pressing block is used for compression, resulting in the processed holes are prone to skew and do not meet the shape. bit tolerance requirements. Existing common jigs, but due to unreasonable structural design, are only used for the processing of single, special parts, and cannot be applied to the holes perpendicular to the center li...

AI Technical Summary

Problems solved by technology

[0003] In the actual processing process, since there is no corresponding drilling jig to fix the shaft parts to be processed well, only a simple pressing plate or pressing block is used for compression, resulting in the processed holes are prone to skew and do not meet the shape. Bit Tolerance Requirements

Some common drilling jigs are available, but due to unreasonable structural design, they are only used for the processing of single and special parts, and cannot be used for processing holes perpendicular to the center line on both ends of shaft parts with different diameters and specifications.
