Description

Technical Field

[0001] The utility model relates to the technical field of dynamic ring detection devices, in particular to a dynamic ring detection tooling. Background Art

[0002] The dynamic ring is one of the key parts in the helicopter lift system. It is made of aluminum alloy and has the characteristics of large size, high precision, multiple test sizes, and long test cycle, which requires high test technology. In the past, there was no special test tooling. The test method was to screw four equal-height support rods to the bottom plate, then place the dynamic ring on the four equal-height support rods, and complete the clamping of the parts with two pressure plates. After a period of testing, it was found that the original test method had the following problems:

[0003] 1. The clamping preparation steps of parts before testing are cumbersome and time-consuming, resulting in a waste of testing preparation time.

[0004] 2. The clamping of parts during testing can easily cause the parts to deform, resulting in poor testing stability and easy to cause human errors in measurement.

[0005] 3. Since the shape of the parts to be tested is relatively complex and requires high precision, three sets of probes are needed to complete the part inspection. The position of the parts and the probes must be adjusted for each inspection. The inspection cycle is long, and the inspection time for a single part is about 7 hours, which cannot meet the industrial inspection needs of mass production.

[0006] In response to the above-mentioned problem, the dynamic ring detection tooling disclosed in the Chinese patent announcement with announcement number CN104511856B has the following technical points: it includes a tooling body, the tooling body is "Y"-shaped, and a first blind hole is provided in the middle position of the upper surface of the "Y"-shaped left arm of the tooling body; a second blind hole is provided in the middle position of the upper surface of the "Y"-shaped right arm of the tooling body, and a third blind hole is provided in the middle position of the upper surface of the "Y"-shaped third arm of the tooling body. The first blind hole, the second blind hole and the third blind hole cooperate with the three reference holes of the dynamic ring to penetrate the positioning pins, and vertically upward elastic pressure plate support columns are respectively provided on the outer sides of the upper surfaces of the "Y"-shaped left arm, the right arm and the third arm of the tooling body; a medium-sized elastic pressure plate is provided on the top of the elastic pressure plate support column, and the medium-sized elastic pressure plate is pressed on the upper surface of the dynamic ring corresponding to the support surface; the clamp fastening screw passes through the through hole to screw the tooling body to the workbench below the tooling body.

[0007] In actual operation, it is found that the above scheme still has at least the following defects: each time the dynamic ring is replaced, the three positioning pins and three support columns need to be manually disassembled and assembled, which is time-consuming, labor-intensive and troublesome. Therefore, we propose a dynamic ring detection tooling to solve the above problem. Utility Model Content
