Problems solved by technology

If a certain piece is worn or the height is inconsistent, it is necessary to add pads such as copper and 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 The same plane, it is usually difficult to meet the requirements for the assembly of workpieces with high precision requirements

Embodiment Construction

[0020] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following will be described in conjunction with the embodiments and accompanying drawings.

[0021] Such as figure 1 with figure 2 As shown, the present invention provides a slope-type adjustment positioning block mechanism, including an upper wedge block 1 and a lower wedge block 2 that cooperate with each other. The lower wedge block 2 is used to be fixedly connected with the positioning base 3 of the workpiece, and at least two mutual The matching upper wedge block 1 and lower wedge block 2 realize the support and positioning of the workpiece;

[0022] The bottom surface of the upper wedge block 1 is provided with a slope I101, and a part of the top surface of the lower wedge block 2 is provided with a slope II201 matching the slope of the slope I101. The horizontal angle of the slope I101 and the slope II201 is consistent, so that the upper wedge block 1 ...

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...
