Problems solved by technology

However, the cost increase of this method is significant due to the difficult disassembly and assembly of many actual parts
[0007] To sum up, due to the absence of a rapid evaluation method, the existing technology has a high cost when solving the assembly problem of the hole system slider and the shaft system guide rail that are difficult to be completely interchanged

Embodiment Construction

[0042] The following are specific embodiments of the present invention, and the solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

[0043] The comprehensive installation error rapid evaluation method of the hole system slider consists of the following steps (unit: mm, radian):

[0044] Step 1. Obtain the geometric design parameters and measuring points of the hole system slider.

[0045] There is a hole system slider on the part; the slider hole system is composed of 4 guide rail shafts; the slider hole system is evenly distributed on a cylinder with a nominal diameter of 25 perpendicular to the section; the nominal size of the slider holes is 4; The nominal depth of the block hole is 20.

[0046] Put one end face of the hole system slider close to the measuring coordinate system xO plane, the center of the slider hole system is close to the measurement coor...

Abstract

The invention relates to the field of computer-aided measurement, in particular to a comprehensive installation error rapid evaluation method for a hole-series sliding block based on mathematical evaluation, the method comprises the following three steps: 1, acquiring geometric design parameters and measuring points of the hole-series sliding block; 2, solving the fitting radius and the fitting azimuth deviation of each sliding block hole; 3, solving the comprehensive installation error of the hole system sliding block according to the fitting radius, the fitting translation error, the fitting angle error, the nominal diameter, the distribution circle diameter, the hole length and the hole number of the sliding block holes.

Description

technical field [0001] The invention relates to the field of computer-aided measurement, in particular to a comprehensive installation error rapid evaluation method of a hole system slider based on mathematical evaluation. Background technique [0002] Hole sliders and shaft guides are widely used in the mechanical field. At present, the minimum clearance (reflecting the assemblability) and the maximum clearance (reflecting the assembly accuracy) of the bore system slider and the shafting guide rail are mainly controlled by controlling the dimensional tolerance and position tolerance of the slider bore system and the guide rail shaft system. [0003] If the dimensional tolerance and geometric tolerance of the design are appropriate, and the dimensional and geometric errors of the parts are in line with the design tolerances, then the assemblability and assembly accuracy of the parts can be guaranteed. At this point, parts are fully interchangeable. [0004] If the dimensio...
