Technical Field
The invention belongs to the field of tool manufacturing, and relates to a laser measurement adjusting method of a curved surface appearance positioning piece and a positioning installation measuring method of a cross lug and an intersection point hole of a hole with the diameter smaller than 8 mm.
Background
An aircraft assembly fixture is an assembly fixture specific to the aviation industry, and the manufacturing accuracy of aircraft components is affected by the part manufacturing accuracy, but depends mainly on the assembly stage. Such as positioning methods, connection methods, and processes during assembly, all affect the final accuracy of the assembly. The development of the jig mounting and measuring technology has very practical significance for shortening the airplane mounting period, ensuring coordination and interchange and improving the labor productivity, so that how to select a reasonable, quick and accurate jig mounting method is a problem which is paid more attention to by people at present.
Through using the laser tracker to assemble and detect the frock, to reducing the assembly fixture, shorten production preparation cycle, improve assembly efficiency, improve the assembly production line to the assembly object, the quick response ability of assembly process flow and the certain degree change of assembly production beat, respond to user's demand fast, to the different requirements of model number improvement, modification, assembly work ability rapid recombination production to improve aviation enterprise competitiveness.
The application of present laser tracker is more and more extensive, and the drawing dimensional requirement can be fast accurate assurance with the frock of laser tracker installation, and the structure of product can not set up special specification along with the specification of laser target seat, and the target seat specification of purchase is limited, and the manufacturing cycle is longer, for the product quality of guaranteeing production cycle and installation frock, improves the installation accuracy simultaneously, and the adapter that has now designed below is used for adjusting the installation location of installing fork ear hole part.
Disclosure of Invention
The invention overcomes the defects in the prior art, and the laser tracker is characterized in that light cannot be shielded, and measurement cannot be carried out if the light is shielded, while the use surface in a certain spherical frame clamp is an OTP point on the lower bottom surface, the use surface is wider without shielding the sight line during initial installation and is not influenced during adjustment, while the sight line is shielded due to the working ladder arranged around the use surface during fixed inspection, and the OTP point on the lower bottom surface cannot be measured.
The laser measuring adapter can also be used for adjusting, installing and measuring fork ear parts with larger notches and the aperture less than or equal to 8 mm.
The method provides a quick and simple installation method for adjusting and installing the fixture, and the method can ensure that the fixture is more convenient to install, the installation process is simple and efficient, and the installation precision is greatly improved.
Adopt and measure the adapter, convert the location of lateral surface to inboard use face through locating washer, through measuring adapter and nut with the use face of location fork ear and the close laminating of locating washer, need not artificial going to hold up and measure the adapter, reduced the measuring error that the human factor brought to operating personnel has been reduced.
