Description

Technical Field

[0001] This utility model relates to the field of measuring fixture technology, and in particular to a measuring fixture for a turbine engine compressor adapter. Background Technology

[0002] Throughout the entire lifecycle of a turbine engine, from precision manufacturing to regular maintenance, the dimensional and positional accuracy of the compressor adapter plays a crucial role. In the field of automated measurement, coordinate measuring machines (CMMs) are commonly used equipment. A CMM mainly includes a marble platform, a crossbeam, and a measuring probe. When measuring parts, it is necessary to establish a reference on the part and align its position. The coordinate data of the object's surface is obtained by moving the measuring probe in three coordinate directions in space, thus achieving high-precision measurement.

[0003] When encountering irregular structures or complex reference point areas, a significant amount of time is spent establishing the reference. Furthermore, when encountering structural obstacles, additional probe angle rotation is required, which consumes even more time. This drawback becomes even more pronounced during mass production, severely limiting the company's production capacity. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: when the structure of the reference point area is complex, a lot of time is spent in the reference establishment stage. At the same time, when there is a structural obstacle, additional probe angle rotation is required, which consumes even more time. This shortcoming is more obvious when mass production is involved, which seriously limits the production capacity of enterprises. Therefore, the proposed turbine engine compressor adapter measuring fixture is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A measuring fixture for a turbine engine compressor adapter includes a base, on which a first positioning seat and a second positioning seat are fixedly mounted. A horizontal quick clamp is fixedly mounted on the first positioning seat, and the part to be measured is placed on the first positioning seat.

[0007] The base is provided with a first limiting part, a second limiting part and a third limiting part. The first limiting part is composed of a first top head, a second top head and a third top head, and the second limiting part is composed of a first contact and a second contact.

[0008] Preferably, a rectangular groove is formed at one corner of the first positioning seat, the first top head is fixedly installed on the horizontal inner wall of the rectangular groove, and the third top head and the second top head are respectively fixedly installed at the other corner of the first positioning seat.

[0009] Preferably, the first contact is fixedly installed on the side of the second positioning seat, a support block is fixedly installed on the first positioning seat, and the second contact is fixedly installed on the side of the support block.

[0010] Preferably, the third limiting part is installed on the vertical inner wall of the rectangular groove, and the third limiting part is perpendicular to the first top head.

[0011] Preferably, the horizontal quick clamp is fixedly mounted on the top of the support block, with one end of the horizontal quick clamp positioned directly above the part to be measured.

[0012] Preferably, a handle is fixedly installed on the side of the base, and an anti-slip sleeve is fixedly installed on the handle. The anti-slip sleeve is made of rubber.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. When using, place the part to be measured on the first positioning seat, adjust the position of the part to be measured so that it contacts the first limit part, the second limit part and the third limit part, and fix it with the horizontal quick clamp. Use the three coordinate measuring machine program to measure the part. Only the coordinate alignment position needs to be established once. This operation is not required for subsequent part measurements, which effectively saves time and costs.

[0015] 2. The measuring fixture takes into account the clamping and assembly of the parts during subsequent processing, which can better meet the processing and usage requirements.

[0016] 3. It reduces the programming difficulty of coordinate measuring machines, increases operational stability, and reduces personnel training costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-2 A measuring fixture for a turbine engine compressor adapter includes a base 1, on which a first positioning seat 2 and a second positioning seat 3 are fixedly mounted. A horizontal quick clamp 4 is fixedly mounted on the first positioning seat 2. A part to be measured 5 is placed on the first positioning seat 2. The base 1 is provided with a first limiting part 21, a second limiting part 31 and a third limiting part 22. The first limiting part 21 is composed of a first top head 211, a second top head 212 and a third top head 213. The second limiting part 31 is composed of a first contact 311 and a second contact 312.

[0022] Place the turbine engine compressor adapter measuring fixture onto the coordinate measuring machine table and fix it in place. Use a coordinate measuring machine (which is existing technology and is not shown in the figure) to establish a reference coordinate system on the measuring fixture.

[0023] A rectangular groove is provided at one corner of the first positioning seat 2, and the first top head 211 is fixedly installed on the horizontal inner wall of the rectangular groove. The third top head 213 and the second top head 212 are respectively fixedly installed at the other corners of the first positioning seat 2.

[0024] The first contact 311 is fixedly installed on the side of the second positioning seat 3. A support block is fixedly installed on the first positioning seat 2, and the second contact 312 is fixedly installed on the side of the support block.

[0025] The third limiting part 22 is installed on the vertical inner wall of the rectangular groove, and the third limiting part 22 is set perpendicular to the first top head 211.

[0026] The horizontal quick clamp 4 is fixedly installed on the top of the support block, with one end of the horizontal quick clamp 4 located directly above the part 5 to be measured.

[0027] A handle 6 is fixedly installed on the side of the base 1. An anti-slip sleeve is fixedly installed on the handle 6. The anti-slip sleeve is made of rubber, which makes it easy for workers to lift the fixture through the handle 6 and move it.

[0028] In this invention, when measuring the compressor adapter of a turbine engine, the part to be measured 5 is placed on the first positioning seat 2, and then the position of the part to be measured 5 is adjusted so that it contacts the first top head 211, the second top head 212, the third top head 213, the first contact 311, the second contact 312 and the third limiting part 22.
