Description

Technical Field

[0001] This utility model relates to the field of metal products, and in particular to a groove depth detection fixture. Background Technology

[0002] In the processing of a metal product, which consists of several matrix-distributed slots, the detection of slot depth is a challenge, including the following issues: 1. The groove depth is relatively small, for example, 0.5mm-3mm; 2. The groove is quite long, making inspection difficult; 3. Visual inspection is computationally difficult and involves a large number of operations. Furthermore, since metal materials generally have reflective surfaces, the depth of the groove is also difficult to detect. Utility Model Content

[0003] The main purpose of this utility model is to provide a groove depth detection fixture, which aims to detect the groove depth of a product through a predetermined fixture, and then, in conjunction with the operator's inspection tools or visual inspection device, to detect the groove depth of the product, effectively improving the convenience of inspection.

[0004] To achieve the above objectives, this utility model proposes a groove depth detection fixture, comprising: The product has multiple spaced elongated protrusions, and an elongated groove is provided between adjacent elongated protrusions; The testing fixture includes a main body and a contour groove located in the middle of the main body. The contour groove is adapted to the shape formed by the outer periphery of the elongated protrusion. The contour groove is provided with a detection strip that extends into the elongated groove. The detection strip has a predetermined thickness and a plurality of spaced detection holes.

[0005] In actual testing, the testing fixture is placed inside the product, and the testing strip extends into the long groove. Using the predetermined thickness of the testing strip and the testing holes, multiple testing holes serve as positioning reference points, enabling precise testing at more locations. Simultaneously, the relative height between the side of the testing hole and the protruding part of the long strip can be used to determine whether the requirements are met. For example, a polarizing microscope is used manually to achieve detection. In automation, a refracting light source can be used to detect the relative gap between the side and the elongated protrusion, thereby enabling the detection of precision dimensions.

[0006] For example, when detecting height, multiple points can be used for detection. Attached Figure Description

Detailed Implementation

[0009] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0010] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0011] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0012] like Figures 1 to 3 As shown, a groove depth measuring fixture includes: Product 1, wherein the product 1 is provided with a plurality of spaced elongated protrusions 11, and an elongated groove 12 is provided between adjacent elongated protrusions 11; The testing fixture includes a main body and a contour groove located in the middle of the main body. The contour groove is adapted to the shape formed by the outer periphery of the elongated protrusion 11. The contour groove is provided with a detection strip extending into the elongated groove 12. The detection strip has a predetermined thickness and a plurality of spaced detection holes.

[0013] In actual testing, the testing fixture is placed inside product 1, and the testing strip extends into the elongated groove 12. Using the predetermined thickness of the testing strip and the testing holes, multiple testing holes serve as positioning reference points, enabling precise testing at more locations. Simultaneously, the relative height between the side of the testing hole and the elongated protrusion 11 can be used to determine whether the requirements are met. For example, a polarizing microscope is used manually to achieve detection. In automation, a refracting light source can be used to detect the relative gap between the side and the elongated protrusion 11, thereby enabling the detection of precision dimensions.

[0014] For example, when detecting height, multiple points can be used for detection.

[0015] In this embodiment of the invention, the outer peripheral wall of the detection hole is provided with a side edge, wherein the advantage of the side edge is that detection can be achieved through relative spacing.

[0016] Specifically, a predetermined width is provided between adjacent detection strips. The predetermined width is used to detect the wall thickness of the elongated protrusion 11. Therefore, this structure can achieve comprehensive detection. If the detection strip cannot be accurately inserted into the groove, its size will also fail to meet the standard.

[0017] In this embodiment of the utility model, a limiting groove is provided on the outer periphery of the elongated protrusion 11, and the main body is stuck in the limiting groove, thereby achieving a fit.

[0018] Specifically, the product 1 and the testing fixture are made of aluminum alloy.

[0019] In this embodiment of the invention, the depth of the elongated groove is 0.2-0.5mm ± 0.05mm.

[0020] Specifically, the width of the elongated protrusion 11 is 0.1-0.2mm ± 0.05mm.

[0021] The depth tolerance of the elongated groove is ±0.05.

[0022] The width tolerance of the elongated protrusion is ±0.05.

[0023] Therefore, the dimensional precision is high and the size is small. In this embodiment of the invention, the detection hole is a circular hole. The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
