A plurality of positioning pins 11 are protruded from the upper end surface of the working table plate 1 and used for assembling connecting holes of the horizontal angle pieces 2a of the air inlet pipe 1 a; the slide rail 2 is arranged on the working bedplate 1; the slide rail 2 in this embodiment is two sets of, corresponds every group slide rail 2 and all is equipped with slider 5.
The slide block 5 can be arranged on the guide groove 21 of the slide rail 2 in a reciprocating way; the detection block 3 is arranged on the slide block 5 and can move along with the slide block 5; the detection block 3 comprises a connecting part 31 and detection parts 32 positioned on two sides of the connecting part 31, the connecting part 31 is fixedly connected with the slider 5, the detection parts 32 extend upwards to be formed on the connecting part 31, and right-angled L-shaped notches 33 are formed in the detection parts 32.
The middle part of the attaching block 4 is rotatably arranged at the front end of the detecting block 3, specifically, the middle part of the attaching block 4 is provided with a convex rotating shaft part, the detecting part 32 is provided with a shaft hole which is rotatably matched with the rotating shaft part, and the rear end surface of the attaching block 4 and the gap 33 of the detecting block 3 form a detecting seam 10; the front end of the fitting block 4 is provided with a fitting groove 41 which is matched with the pipe wall of the air inlet pipe 1 a. The rear end face of the fitting block 4 is inclined away from the vertical direction. The fitting block 4 is provided with hole position pins 42 capable of positioning the mounting holes of the bevel blades 4 a.
The detection tool is provided with a detection feeler gauge, and the size of the detection angle is determined according to the passing performance of the detection feeler gauge extending into the detection seam. The detection feeler gauge can be divided into a detection feeler gauge for detecting a large opening and a detection feeler gauge for detecting a small opening, and the detection feeler gauge can be set according to specific detection angle requirements.
As shown in fig. 3, the reference plane M and the inclined plane N are the angle α to be measured.
Referring to fig. 7, the angle detection method includes the following steps:
firstly, an air inlet pipe 1a is arranged on a work table board 1, the bottom surface of the air inlet pipe 1a is ensured to be attached to the upper end surface of the work table board 1, and a horizontal corner piece 2a on the air inlet pipe 1a is positioned by a positioning pin 11;
secondly, moving the attaching block 4 to enable the pipe wall of the air inlet pipe 1a to be closely attached to the attaching groove 41, and enabling the front end face of the attaching block 4 to be closely attached to the bevel sheet 4 a;
and thirdly, observing the shape of the gap between the front end surface of the detection block 3 and the rear end surface of the attaching block 4, and determining whether the size of the inclination angle of the angle piece 4a is in a specified tolerance range or not by combining the trafficability of the detection feeler gauge in the gap.
As shown in fig. 8 to 10, when the angle between the rear end surface of the attachment block 4 and the top surface is 87.5 ° (as shown in fig. 6), and the measured angles are 90 °, 87.5 °, and 87 ° after the attachment block 4 is attached to the bevel sheet 4a, respectively, the gap value X of the corresponding port of the detection slit 10 is changed from 0 to X1, and then increased to X2. When the measured angle range is 87 degrees to 87.5 degrees, the range of the gap value is X1 to X2. Then, during detection, only the feelers of X1 and X2 are needed to measure the angle. In order to ensure the reliability and accuracy of detection, the attaching block 4 must be closely attached to the detected inclined plane, and an attaching oblique angle cannot exist.
Taking the detection of one bevel angle sheet 4a as an example for explanation, the air inlet pipe 1a is flatly placed on the detection table top, is positioned by the 3 positioning pins 11, and moves the sliding block 5, so that the detected inclined plane is tightly attached to the attaching block 4, and the detection seam 10 appears between the detection part 32 and the rear end face of the attaching block 4. The detection method comprises the following steps: plugging a 1.24mm feeler gauge into the detection slot 10, and if the feeler gauge can be plugged to the bottom, proving that the angle alpha is less than 87 degrees and is an unqualified product; if the 1.24mm feeler is not plugged to the bottom and is present by visual inspection, the angle α is greater than or equal to 87 °, which is a method for detecting an angle of 87 ° at the lower limit. As can be seen from fig. 10, when the angle α is equal to 87.5 °, the two surfaces of the gap are parallel, the detection method can be visually observed, as long as the detection slit 10 gradually increases from the bottom to the top, which indicates that the angle is smaller than 87.5 °, and the detection method can observe whether the opposite surfaces of the detection block 3 and the attachment block 4 are flush, and if a significant obtuse angle exists and the opening of the obtuse angle is downward, which also indicates that the angle is smaller than 87.5 °. If the plug cannot be determined visually, the plug can be judged whether the plug can be plugged to the bottom or not by a 1.09mm plug gauge. Generally, the method only needs to detect the position of the feeler gauge by 1.24mm once.
It can be seen that the gap gradually increases from small to large, and the height of the bottom surface of the notch 33 can be appropriately modified to adjust the measurement range of the gap in view of the tolerance of 0.5 °. If the bottom surface of the notch 33 is designed to be higher, the range of the gap value will be changed to 1.11-X, where X will be greater than 1.24, and conversely, less than 1.24. Therefore, the actual measurement gap can be properly adjusted according to the tolerance of the measured angle, and if the angle tolerance is smaller, the bottom surface of the notch 33 can be properly moved upwards to increase the gap value; if the angular tolerance is large, the bottom surface of the notch 33 can be moved down properly, and the measured gap value is reduced. Therefore, the measuring method has certain adjustment allowance, and the measuring precision can be ensured
The detection method in the embodiment is convenient to operate, accurate in measurement and suitable for detecting the included angle between two general non-contact surfaces. The design principle is that the joint block 4 is jointed with the detected surface, and the clearance is detected through the feeler gauge. In practical application, the structure of the part can be modified to measure different basic angular dimensions and tolerances, and the universal measuring device has good universality.
