Problems solved by technology

Although the comprehensive measurement of mechanical parts can be realized by using a three-coordinate measuring machine, the existing three-coordinate measurement technology cannot realize various runout errors such as the rotation of the measured axis. In addition, when measuring shape and position errors, such as Roundness error, in order to obtain accurate measurement results, a large amount of measurement data is required. For this requirement, three coordinate measuring machines are difficult to meet the requirements
[0003] In the prior art, the size and shape errors of parts are generally measured by special equipment, but shaft parts have various size and shape errors, which are difficult to detect with existing equipment, costly, and even impossible to measure
[0004] Although the combination of the above-mentioned instruments can realize the measurement of some parameters of shaft parts, the test cycle is long and consumes a lot of manpower and material resources, which is not conducive to improving work efficiency, and the data of each instrument are independent of each other and cannot be combined.
At present, there is no ability to measure the axial length, radial dimension, taper, axis straightness, axis coaxiality, roundness, cylindricity, perpendicularity of the end to the axis, end runout, etc. of the shaft parts at home and abroad.

Embodiment Construction

[0019] A comprehensive inspection instrument for shaft parts, using granite materials to process the base 1, and processing two parallel air-floating guide rails on the base 1, which are respectively used as measuring guide rails 12 and load-bearing guide rails. The load-bearing guide rails are equipped with load-bearing slides 11, Measuring slides 6 and 9 are equipped on the measuring guide rail, and air flotation air circuit and vacuum adsorption air circuit are respectively installed on the load-bearing slide 11, slide 6, and slide 9. When the air flotation air circuit is ventilated, the gas can be Let the sliding table float a few microns to tens of microns for easy movement, and when the vacuum adsorption chamber is evacuated, the sliding table can be firmly fixed due to the pressure difference. A headstock 2 and a tailstock 10 are installed respectively on the left end of the base and the load-bearing guide rail 11, and the top alignment straight line of the headstock 2 a...

Description

technical field [0001] The invention relates to special equipment for detecting the geometric parameters of shafts and shaft parts, in particular to a special device capable of comprehensively detecting the geometric parameters of shaft parts. Background technique [0002] Shaft parts are key parts commonly used in the machinery industry. Shaft parts contain many geometric parameters, including axial length dimensions, radial dimensions, taper, axis straightness, and axis coaxiality of shaft parts. Degree, roundness, cylindricity, perpendicularity of end to axis, end runout, etc. Shaft parts are also important parts that affect the performance of equipment. The requirements for machining or assembly accuracy are the highest. Some of the geometric parameters require accuracy of tens of microns or several microns, which is higher in high-precision instruments and equipment. . There are many parameters of shaft parts, and different testing instruments are generally used for t...
