Description
Technical field
The invention relates to and measure the pick-up unit that profile has compound angle length.
Background technology
A large amount of high-pressure work blades in the aeromotor are a kind of very high to length dimension L requirement, and profile has the part of compound angle tenon shape, and the detection of this part is a difficult point always.Traditional measuring method is directly to detect with outside micrometer, because the profile of tenon has the quadrilateral of two angles at length direction, this method by manual detection is difficult to the tram of centering tenon length dimension L.Need break during detection and adjust the position of detecting, the result of detection is inaccurate usually, and efficient is very low.Another kind method is that clock gauge is fixed on the microheight gauge, checks length dimension L with standard block gauge, reads indicating value in the clock gauge table again on microheight gauge, shows tested length dimension tolerance.Because the tenon numbers of poles greatly, existing detection method not only efficient is low, and test result is not accurate, and operation is very loaded down with trivial details, and the quality progress is difficult to be held.
Summary of the invention
The present invention seeks to the problem that exists at prior art, provide a kind of simple in structure, easy to operate, detection efficiency is high, can be widely used in the pick-up unit of similar tenon part.
The technical solution adopted for the present invention to solve the technical problems is: a kind ofly measure the pick-up unit that profile has compound angle length, comprise, the fixedly base plate 1 of clock gauge and gauge outfit support 5, it is characterized in that, described gauge outfit support 5 is provided with the horizontal location hole of horizontal placement clock gauge gauge outfit, transverse plane is shaped on the trip bolt hole that connects described horizontal location hole on it, the clock gauge gauge outfit stretches into the perpendicular end surface of stretching out gauge outfit support 5 one sides in the described horizontal location hole, fixing by trip bolt 6, be positioned at inclined-plane location-plate 3 and the long limit of tenon location-plate 3 that described gauge outfit support perpendicular end surface base plate 1 is provided with positioned parallel tenon part.
The present invention has following beneficial effect than prior art.
Pick-up unit of the present invention is simple in structure, and is easy to operate, but utilizes the contact contact tenon fast detecting tenon length dimension tolerance of clock gauge measurement mechanism.Can detect the tenon part of compound angle length rapidly and accurately, under the condition that satisfies the product accuracy requirement, greatly improve work efficiency and detected quality.This testing tool can be widely used in the detection of similar part.
Description of drawings
Fig. 1 is that the present invention measures the principle of work synoptic diagram that profile has the pick-up unit of compound angle length.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1 base plate, 2 side location-plates, 3 inclined-plane location-plates, the long limit of 4 tenons location-plate, 5 gauge outfit supports, 6 holding screws, clock gauge, 8 screws, 9 straight pins, 10 tested part tenons.
Embodiment
Consult Fig. 1, Fig. 2.Have among the pick-up unit embodiment of compound angle length in described measurement profile, fixedly the base plate 1 of clock gauge is the vertical each other bodies that connect firmly with gauge outfit support 5.Be shaped on the horizontal location hole of horizontal placement clock gauge 7 gauge outfits on the gauge outfit support 5.Transverse plane is shaped on the trip bolt hole that connects this horizontal location hole on the horizontal location hole.The clock gauge gauge outfit stretches in the above-mentioned horizontal location hole, stretches out the perpendicular end surface of gauge outfit support one side, and the clock gauge gauge outfit that will be stretched in the above-mentioned horizontal location hole by trip bolt 6 during use is fixed.Be positioned on the above-mentioned gauge outfit support 5 perpendicular end surface base plates 1, be provided with the inclined-plane location-plate 3 and the long limit of the tenon location-plate 3 of positioned parallel tenon part.Inclined-plane location-plate 3 is connected into one by screw 8 straight pins 9 with base plate 1.Exceed the side location-plate 2 on inclined-plane location-plate 3 inclined-planes, be vertically fixed on the perpendicular end surface in left side of inclined-plane location-plate 3, long limit location-plate 4 is locating pieces of location tenon part length direction, it can link into an integrated entity by screw, straight pin and inclined-plane location-plate 3, form incline bench, the step vertical plane of this incline bench parallels with tenon part length direction.
Before the detection, the calibrating device 10 of tested part tenon is put into the tram of Fig. 2, the horizontal location hole of one end push table support 5 of clock gauge 7, clock gauge 7 is the level of state, clock gauge is returned to zero, be fixed by trip bolt 6 then, avoid clock gauge location axle pin horizontal location hole in gauge outfit support 5 to rotate.Adjust mechanical type lever clock gauge 7 this moment, and the contact of clock gauge measurement mechanism is contacted with the tested part outer rim, the length of check tenon.Utilize the tested part tenon to contact with the contact of clock gauge measurement mechanism, the indicating value left and right sides difference of writing down clock gauge is exactly the tested part error in length.This direct measurement is directly to measure measured parameter, and its value is directly read by instrument, is called direct measuring method.
