Abstract
The invention discloses a method for detecting a radius of a swing type blade, which is characterized in that a vertical V-shaped groove (3) is manufactured on one side of a measuring block (1), a head of a dial indicator (5) is inserted into a hole (6) at the middle of the measuring block (1), a core rod (4) with the radius of standard R is adopted for being closely attached to the V-shaped groove (3) so as to get standard value of the dial indicator (5), the circular arc surface of the blade (7) is used for being closely attached to the V-shaped groove (3), the radius value of the circular arc surface of the blade (7), which is obtained by the dial indicator (5), is compared with the standard value, and the blade (7) with the radius value in the standard value range is determined to be qualified. A device has simple structure, is convenient to use, and can directly read the size of the radius R of the circular arc surface of the blade through the dial indicator, the working efficiency is high, the precision is high, the cost is low, and the using value is higher.
Description
Technical field
The present invention relates to a kind of detection method and device of swing blade radius, particularly measure the measurement mechanism of rotor compressor blade radius.
Background technology
Rotor compressor is the core of air-conditioning, blade is the core part on the compressor of air conditioner, the swing blade of my company's production and processing (figure one), wherein the arc surface of radius R accounts for 1/3 of entire working surface, and in processing and testing process, the R size can't directly be used miking, usually adopt projector or universal tool-measuring microscope to measure (need calculate when measuring) at every turn, the method cost height, efficient is low, can't guarantee to produce normal operation.
Summary of the invention
The objective of the invention is to: provide a kind of cost low, simple in structure, the detection method of the swing blade radius that efficiency of measurement is high and device are to overcome the deficiencies in the prior art.
The present invention constitutes like this: the detection method of swing blade radius, measuring the vertical V-type groove of piece one side making, insert the gauge outfit of clock gauge in the hole in the middle of measuring piece, the plug that to adopt 1 radius be standard R is adjacent to the V-type groove, obtain the standard value of clock gauge, arc surface with blade is adjacent to the V-type groove, and blade arc surface radius distance value that clock gauge obtains and standard value compare, and the blade of radius distance value in standard value range is qualified.
The detection method of above-mentioned swing blade radius, the two ends up and down of described standard plug are respectively the upper and lower bound size of blade arc surface radius R.
The pick-up unit of swing blade radius comprises base, is provided with the measurement piece on base, is provided with vertical V-type groove measuring piece one side, measuring on the piece fixedly clock gauge, is provided with the hole in the middle of measuring piece, and the gauge outfit of clock gauge is passed the hole and inserted the V-type groove.
The pick-up unit of above-mentioned swing blade radius, the angle of V-type groove are 90 °.
Of the present invention simple in structure, easy to use, can be by showing directly to read the size of blade arc surface radius R, high efficiency, the precision height, cost is low, has higher use value.
Description of drawings
Accompanying drawing 1 is the structural representation of blade;
Accompanying drawing 2 is a structural representation of the present invention;
Accompanying drawing 3 is determined the synoptic diagram of qualified data for the present invention adopts the standard plug.
Embodiment
Embodiments of the invention: as shown in Figure 2, make base 2, on base 2, install and measure piece 1, produce vertical V-type groove 3 in measurement piece 1 one sides, at the opposite side of measuring piece 1 clock gauge 5 is installed, is being measured piece 1 middle drilling bore hole 6, the gauge outfit of clock gauge 5 is passed hole 6 and is inserted in the V-type grooves 3.The angle of V-type groove 3 is 90 ° of right angles.
During use, as shown in Figure 3, the plug 4 that it is standard R that elder generation adopts 1 radius is adjacent to V-type groove 3, and the gauge outfit of contact clock gauge 5 is adjusted clock gauge 5 and guaranteed that gauge outfit has 30～40um decrement, reads the numerical value of this moment, obtains the standard value of clock gauge 5.During measurement, be adjacent to V-type groove 3, slide up and down with the arc surface of blade 7, blade 7 arc surface radius distance value that clock gauge 5 obtains and standard value relatively, the blade 7 of radius distance value in standard value range is qualified.
Standard value for R, available 1 standard plug 4, the two ends up and down of plug 4 are respectively the upper and lower bound size of blade 7 arc surface radius Rs, plug 4 is adjacent to V-type groove 3, slide up and down, obtain the upper dimension bound and the lower limit of qualified blade 7 respectively, the clock gauge reading value of specification product should drop between the plug 4 upper and lower bound readings.The plug 4 that also can to make 1 radius respectively be the R upper dimension bound and the plug 4 of R lower size limit come the standard value of clock gauge 5 is tested and adjusted.
During measurement, blade 7 is adjacent to V-type groove 3, slides up and down, obtain clock gauge 5 readings of blade 7, to this reading compare judge whether qualified.
