Problems solved by technology

Many mechanical parts or complete machine products have cleanliness quality control indicators and need to be cleaned during the production process. However, due to the troublesome and time-consuming testing methods for the cleanliness of mechanical products, it is difficult to achieve online and timely testing at the production site. Therefore, the study of a method and device that can simply, quickly and accurately detect the cleanliness of mechanical products has practical significance for solving the problem of timely detection of mechanical product cleanliness

Embodiment 1

[0035] like Figure 4 The gear 26 of a certain specification is measured directly with a general electronic referred to as a precision of 0.01 g. The gear 26 before cleaning the gear 26 is placed in a normal electronic referred to in the precision of 0.01 g, and the quality before reading it is stabilized, and the quality prior to the cleaning is stabilized, and it is ΔM1; then the above-mentioned gear 26 is cleaned, dried In the original state, the re-placing accuracy is 0.01G, and the quality of the cleaning is read after the number of copies is stabilized, and the weight difference of the gear 26 is ΔX1 = ΔM1- ΔM2, so repeatedly, the average value of the weight difference is the cleaning degree of the cleaning of the gear 26 of the specification. Because the gear is not required to clean the cleanliness, it can be measured directly with ordinary electronics referred to in the range and accuracy, to demonstrate the rapid detection of the rapid detection of the mechanical parts cl...

Embodiment 2

[0037] like Figure 5 , The ordinary triangular horizontal measuring device is constructed by the left lever arm 18, the right lever arm 19, the left weighing disk 17, the right scales 20, and the precision electron is integrated with 0.001 g of the precision electron, and the main seat 22 and the triangular bracket 25 are commonly constructed. The left lever arm 18 and the right lever arm 19 are located on both sides of the triangular bracket 25, and the left lever arm 18 is suspended a left scales 17, and the right lever arm 19 is hoverted to hang a right scale plate 20, precision electron with accuracy is 0.001G. Located below the left scales 17, the bottom seat 22 is located below the right scale plate. The piston 16 before the same specification is cleaned is placed in the middle of the left scales 17, and the same specification is placed in the middle of the right scales 20, and the precision electron is said to be a precision electron number of 0.001 g of the precision of 0....

Embodiment 3

[0039] See figure 1A quick detection method and apparatus for mechanical components, detecting devices include balance, precision electronics, referred to, 20.001G, retrieval-sitting 22, and balance use air floture supporting balance, gas flotive support Tianping includes: gas Floating Handling System I, Sample Test Area II and Standard Part III III.

[0040] See figure 1 , figure 2 , Figure 3A and Figure 3B The gas float support system includes a gas flore bearing and a fixed bracket 24 including a gas float rotor 1, a gas floating stator 2, and a gear ring 14, and the air float stator 2 is fixedly mounted on the fixed bracket 24, air float The rotor 1 is set to the air floating stator 2, both of which are gaps; the air float stator 2 is a hollow structure, and the air float stator 2 is a compressed air interface 3, and the other end is sealed by the end cap 12, thereby forming a cavity 5; The gear ring 14 is set to one end of the air float stator 2 close to the end cover 12 and ...

Abstract

The invention discloses a method and device for quickly detecting the cleanliness of mechanical parts. The device includes an air-floating support system, a sample detection area and a reference area for standard parts; The weight of the mechanical parts, record the measured value, then clean and dry the mechanical parts to the original state, then detect the weight of the mechanical parts after cleaning, record the measured value, and calculate the weight difference between the two before and after; Repeat the above steps several times to calculate the average weight difference. The average weight difference of the mechanical parts before and after cleaning is the cleanliness of the tested mechanical parts. The invention can simply, quickly and accurately detect the cleanliness of mechanical products including on-line detection at the production site, and has practical significance for solving the problem of timely detection of mechanical product cleanliness. The invention has the advantages of simple structure, low cost and easy operation and application.

Description

Technical field [0001] The present invention relates to the field of mechanical manufacturing techniques, and more particularly to a rapid detection method and apparatus for cleaning of mechanical parts. Background technique [0002] The cleaning degree indicates the amount of dirt remaining on its surface after cleaning. In general, the amount of dirt includes a variety, shape, size, quantity, weight, and the like measures, which indicators depend on the extent of different dirt on product quality and cleanliness control accuracy. The weight method is the most commonly used cleanliness measurement method in industrial production and experiments. The determination principle is to clean under certain conditions, and then fully filtered through the filter, and the dirt is collected in the surface of the dried filter film, which is fully dry again, due to the pollution The amount of material is small, and it is generally necessary to use the analysis of the surface of the filter mas...
