Description

Technical Field

[0001] The utility model relates to the technical field of capillary pore measurement, in particular to a capillary pore measurement tool. Background Art

[0002] Active clearance control technology is used on both high-pressure and low-pressure turbines of aircraft engines. Its main function is to maintain the optimal clearance between the blades and the casing to improve engine performance, that is, to change the amount of cooling air blown to the outer wall of the turbine casing according to different operating conditions. For the high-pressure turbine, when the speed is 80% to 90% and the altitude exceeds 1500m, air is supplied to reduce the clearance between the blade tip and the casing. For the low-pressure turbine, when cruising, the air supply valve is fully opened to reduce the blade tip clearance; it is partially opened during takeoff, and only a small amount of cooling air is supplied to cool the casing during parking and small operating conditions;

[0003] The low-pressure turbine active clearance assembly is mainly used to supply cooling air to the casing surface. The surface of the impact cooling pipe in the low-pressure turbine active clearance assembly needs to be processed in batches. The holes are capillary holes with a diameter of less than φ1, and the number is more than 120. The capillary hole position and size requirements are high and the processing is difficult. After using electric spark or laser drilling, the detection is difficult. The conventional probe size of the existing three-coordinate measuring instrument is difficult to meet the requirements, and the measurement efficiency is low, which does not meet the production needs of large-scale processing;

[0004] At present, the pin insertion method is used to detect capillaries. After the parts are fixed, the pin is inserted into the hole of the part for detection by sliding. It has the advantage of fast detection speed, but it also exposes some problems in practical applications. The angle and height of the pin are usually fixed, which makes the tooling less adaptable to parts of different sizes and shapes, which is not conducive to practical use.

[0005] Therefore, a capillary pore measurement tool is needed to overcome the occurrence of the above problems. Utility Model Content

[0006] In order to solve the above problems, the embodiment of the utility model provides a capillary pore measurement tool, which achieves the purpose of solving the problems raised in the background technology.

[0007] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a capillary pore measuring tool, including a bracket, a connecting block arranged on the bracket, and a detection pin slidably arranged inside the connecting block, and the bracket is provided with a connecting component for adjusting the height of the connecting block; the connecting component includes a slide groove opened inside the bracket, a support block slidably arranged inside the slide groove, and a fastening nail threadedly connected to the support block for fixing the support block inside the slide groove.

[0008] As a further improvement of the above technical solution:

[0009] The connecting assembly is provided with an adjusting assembly for adjusting the inclination angle of the connecting block.

[0010] The adjustment component comprises a second fastening nail which is threadedly connected to the inside of the support block; and the connection block is rotatably arranged outside the second fastening nail.

[0011] One end of the first fastening nail and one end of the second fastening nail are both fixedly connected with a knob.

[0012] One side of the knob is fixedly connected with an anti-skid pad.

[0013] A bottom plate is arranged at the bottom of the bracket, the connecting block is located above the bottom plate, a side of the bottom plate close to the connecting block is a plane, and a side of the connecting block close to the bottom plate is a plane.

[0014] The beneficial effects of the embodiments of the utility model are:

[0015] In actual use, after loosening the fastening nail 1, the support block can slide inside the slide groove 1, and the height of the connection block can be adjusted. After the height is adjusted to a suitable position, the fastening nail 1 is tightened, and the height adjustment of the detection pin shaft can be completed. The height of the connection block can be adjusted according to the actual size of the part, which is convenient for actual detection and use;

[0016] The connecting component is provided with an adjustment component for adjusting the inclination angle of the connecting block. The inclination angle of the connecting block is adjusted through the connecting component, thereby adjusting the inclination angle of the detection pin shaft, so as to facilitate adjusting the height and inclination angle of the detection pin shaft according to the actual size of the part and the angle of the hole position.
