Description

Technical Field

[0001] This utility model belongs to the field of inspection tool technology, and specifically provides a diffuser housing inspection tool. Background Technology

[0002] A diffuser is a device that splits, diffuses, and discharges fluids, and it has wide applications in various sub-branches of the industrial field.

[0003] Considering the differences in the number and spacing of holes on the surface of diffuser housings for different needs or different batches, the current fixture structure is relatively fixed. Fixtures usually need to be customized one by one according to the workpiece to be inspected. Long-term production and operation will accumulate a large number of fixtures, occupying workpiece storage space. Moreover, errors may occur in the process of storage, archiving and repeated use, leading to mis-inspection or the need to re-customize fixtures. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a diffuser housing inspection fixture, including a base, a pad, a first detection unit, a hole inspection unit and a second detection unit, wherein the hole inspection unit is assembled at the center of the upper surface of the base, and the pad and the second detection unit are evenly distributed around the hole inspection unit.

[0005] The hole inspection unit consists of a base block, an annular airbag, an assembly base, and a detection column. The surface of the base block has multiple assembly slots. Each assembly slot has an inner ring groove and an outer ring groove on its inner sidewall. An annular airbag is embedded in both the inner and outer ring grooves. Both annular airbags protrude into the assembly slots, and there is a gap between the two annular airbags. Multiple assembly bases are engaged between the two annular airbags, and the detection column is assembled on the corresponding assembly base.

[0006] Furthermore, the hole inspection unit also includes an air bladder and an adjusting bolt. The annular air bladder includes an active annular air bladder and a passive annular air bladder. The active annular air bladder and the passive annular air bladder are used in pairs and are respectively embedded in the inner ring groove and the outer ring groove. A compression chamber is opened on the side wall of the base block. The adjusting bolt is screwed into the compression chamber. The air bladder is arranged in the compression chamber and is connected to the active annular air bladder through a pipeline.

[0007] Furthermore, the longitudinal section of the mounting base is "τ" shaped, that is, the inner and outer rings of the side wall of the mounting base are full grooves or half grooves respectively, and the bottom of the half groove side wall is rounded.

[0008] Furthermore, the surface of the mounting base is integrally formed with a tapered connecting post, and the connecting post has an internal thread inside;

[0009] Correspondingly, a cavity is provided on the end face of the detection column, and a screw is installed in the cavity. The detection column is connected to the mounting base by screwing.

[0010] The beneficial effects of using this utility model are:

[0011] The hole inspection unit of this utility model consists of a modular base block, an assembly base, and an inspection column. For diffuser shells under inspection in the same batch where the hole distribution radius does not differ significantly, only one customized base block needs to be retained. The assembly base and inspection column can be configured according to requirements, reducing the number of inspection units accumulated during long-term production activities in the workshop. At the same time, the assembly base and inspection column can be removed when the hole inspection unit is not in use, and the space occupied by storing only the base block is also less than that of similar inspection units.

[0012] In summary, production costs can be reduced by both decreasing the number of custom-made inspection tools and reducing the storage costs of inspection tools.

[0013] Meanwhile, each time the inspection tool is used, the staff needs to reconfigure the assembly base and inspection column according to the drawings. The configuration results usually do not have serious errors, avoiding situations where the inspection tool is called incorrectly. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] Reference Figures 1-4A diffuser housing inspection fixture includes a base 1, a pad 2, a first detection unit 3, a hole inspection unit 4, and a second detection unit 5. The hole inspection unit 4 is assembled at the center of the upper surface of the base 1, and the pad 2 and the second detection unit 5 are evenly distributed around the hole inspection unit 4.

[0025] Specifically, the hole inspection unit 4 consists of a base block 401, an annular airbag, an assembly seat 406, and a detection column 407. The surface of the base block 401 is provided with multiple assembly grooves 402. Each assembly groove 402 has an inner ring groove and an outer ring groove on its inner sidewall. An annular airbag is embedded in both the inner ring groove and the outer ring groove. Both annular airbags protrude into the assembly groove 402, and there is a gap between the two annular airbags. Multiple assembly seats 406 are engaged between the two annular airbags, and the detection column 407 is assembled on the corresponding assembly seat 406.

[0026] Preferably, the shape of the base block 401 matches the shape of the diffuser shell 6.

[0027] Reference Figure 5 During the inspection process, the diffuser shell 6 is fastened onto the hole inspection unit 4;

[0028] Before the initial inspection begins, select and deploy the mounting base 406 and the inspection column 407 according to the standard hole positions and diameters of the diffuser shell 6.

[0029] Assembly slot 402 can be left empty;

[0030] As shown in the example, there are three assembly slots 402. However, if the holes in the diffuser housing to be inspected are distributed in two rings, then one assembly slot 402 will be empty.

[0031] Preferably, the hole inspection unit 4 further includes an air bladder 405 and an adjusting bolt 409. The annular air bladder includes an active annular air bladder 403 and a passive annular air bladder 404. The active annular air bladder 403 and the passive annular air bladder 404 are used in pairs and are respectively embedded in the inner ring groove and the outer ring groove. A compression chamber 408 is provided on the side wall of the base block 401. The adjusting bolt 409 is screwed into the compression chamber 408. The air bladder 405 is arranged in the compression chamber 408. The air bladder 405 is connected to the active annular air bladder 403 through a pipeline.

[0032] Tightening the adjusting bolt 409 compresses the air bladder 405. The gas inside the air bladder 405 is conducted through the pipeline to the active annular air bladder 403, which drives the active annular air bladder 403 to expand and output thrust outward.

[0033] The clamping strength of the annular airbag to the mounting base 406 is adjustable, and continuous squeezing of the airbag 405 can provide greater pressure and achieve a better clamping and fixing effect.

[0034] Meanwhile, the distribution radius of the detection column 407 can be finely adjusted according to the degree of compression of the passive annular airbag 404.

[0035] The longitudinal section of the mounting base 406 is "τ" shaped, that is, the inner and outer rings of the side wall of the mounting base 406 are full groove 4061 or half groove 4062 respectively, and the bottom of the side wall of the half groove 4062 is rounded.

[0036] During the installation of the mounting base 406, first push one side of the full groove 4061 obliquely into the mounting groove 402, and at the same time forcefully compress the annular airbag with the full groove 4061, press the half groove 4062 into the mounting groove 402.

[0037] The surface of the mounting base 406 is integrally formed with a tapered connecting post 4063, and the interior of the connecting post 4063 is provided with internal threads.

[0038] Correspondingly, a cavity is provided on the end face of the detection column 407, and a screw is installed in the cavity. The detection column 407 is connected to the mounting base 406 by screwing.

[0039] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the concept of this utility model. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this utility model.
