Slope type positioning block adjusting mechanism

Abstract

The invention discloses a slope type positioning block adjusting mechanism. The slope type positioning block adjusting mechanism comprises an upper wedge block and a lower wedge block which are matched with each other, wherein a slope I is arranged on the bottom face of the upper wedge block, and a slope II matched with the slope I in inclination is arranged on one part of the top face of the lower wedge block, so that a positioning horizontal plane is formed on the top face of the upper wedge block; a protruding block is arranged on the other part of the top face of the lower wedge block, a counterbore I is formed in the side face of the protruding block, and the whole counterbore I is a vertical oblong hole; a screw hole opposite to the counterbore I is formed in the side face of the upper wedge block, and a double-end bolt with the two ends being opposite in rotating direction is arranged between the upper wedge block and the protruding block; and one end of the double-end bolt is connected with the screw hole, the other end of the double-end bolt penetrates into the counterbore I and is connected with a nut in a rotating mode, and an inner hexagon is further arranged at the topend of the other end of the double-end bolt. The slope type positioning block adjusting mechanism is simple in structure and convenient to adjust, the adjusting precision can be controlled within 0.003 mm, and in addition, the mechanism has universality, can be used on common or precision equipment and can also be used on a tool clamp.

Description

technical field [0001] The invention relates to the technical field of engine component installation, in particular to an inclined plane type adjustment positioning block mechanism. Background technique [0002] During the assembly or production process of engine workpieces, due to the irregular structure at the bottom of some workpieces, the positioning usually requires multiple positioning blocks to support them. The repeated lamination of the positioning surface is more reliable. If a certain piece is worn or the height is inconsistent, it is necessary to add pads such as copper or steel to level the traditional positioning block. The thickness of the copper or steel is often above 0.01mm, so that the height of multiple positioning blocks cannot be controlled. Myopia On the same plane, it is usually difficult to meet the requirements for the assembly of workpieces with high precision requirements. Contents of the invention [0003] Aiming at the problems existing in t...
