Drill positioning guider

Abstract

The invention discloses a drill positioning guider, and belongs to the technical field of aerospace manufacturing. The drill positioning guider comprises a positioning block, a mounting seat and a guide block, wherein the positioning block takes the shape of an inverted frustum with a hole in the center; a small head end of the positioning block can be put into a prefabricated nail hole; the bottom surface of the small head end is a positioning surface; the positioning surface is perpendicular to the normal direction of the bottom surface of the prefabricated nail hole of a to-be-machined part; the shape of the positioning block is matched with the contour of the prefabricated nail hole; the hole is drilled in the center of the guide block; the central hole of the guide block is matched with a drill bit used for machining the drill hole; one end of the guide block is connected with a big head end of the positioning block, and the central hole is concentric; the component which is formed by connecting the guide block with the positioning block is named as a positioning guide body; the positioning guide body is fixedly arranged on a mounting seat; the axis of the positioning guide body is in the same direction as the normal direction of the positioning surface of the positioning block. According to the drill positioning guider, the machining precision and the working efficiency of the hole can be greatly improved, and the production cost is reduced; the drill positioning guider has a simple structure, is convenient to operate and can be widely popularized in production.

Description

technical field [0001] The invention belongs to the technical field of aviation manufacturing, and in particular relates to a drilling positioning guide used in the drilling process. Background technique [0002] The currently used drilling guide (also known as drilling guide sleeve) is mainly through the tight fit between the bottom surface of the locator and the surface of the part to be processed to ensure that the drilling direction is in the same direction as the normal direction of the surface of the part to be processed. . When drilling, it is necessary to ensure that the bottom surface of the locator is in full contact with the surface of the part to be processed, and it is also required that the part to be processed has a guide hole that has been determined in the correct position. [0003] In actual work, sometimes it is necessary to drill the initial hole on the part to be processed through the corresponding positioning drilling device and then process the hole r...

Problems solved by technology

[0004] In order to solve the technical problem that the drilling guide in the prior art only has a guiding function and has no positioning function, and the drilled hole is difficult to be coaxial with the prefabricated nail socket, so it cannot well meet the assembly accuracy requirements of the aircraft. In the way of reverse thinking, starting from the nail socket already made, first cooperate with the prefabricated nail socket through the drilling positioning guide disclosed in the present invention to determine the position of the drilling positioning guide relative to the part to be processed, that is, to determine The position of the hole of the part to be processed is ensured by ensuring that the small end of the positioning block of the drilling positioning guide fits with the prefabricated nail socket, and the bottom surface of the small end is perpendicular to the normal direction of the bottom surface of the prefabricated nail socket of the part to be processed to ensure that the drilled hole is in line with the prefabricated nail socket. The concentricity of the prefabricated nail socket, this design is a portable auxiliary device integrating guidance and positioning, which greatly improves the processing quality and processing efficiency
