AI Technical Summary
Existing inspection tooling cannot effectively identify whether the holes are completed inside the parts, resulting in leaking holes being often ignored, which in turn causes the customer to bump the knife during processing.
A leak-punching inspection tool set is designed, including tooling body, hole inspection and appearance inspection. The hole detection is arranged in the middle of the workpiece body and cooperates with the inner hole of the part; the shape detection surrounds the hole detection and cooperates with the shape of the part. Through this tooling, the inner hole of the part is in harmony with the hole detection, and the outer surface is in harmony with the shape detection, so that the tooling can be put into the tooling smoothly. Otherwise, the inner hole and the hole detection will interfere with each other, which will achieve effective detection of whether the part has been drilled.
The leak-punching inspection tooling can effectively monitor whether the parts have completed the punching operation, avoiding the parts that have not completed the punching out of the production line, and ensuring the improvement of product quality.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of tooling, in particular to a tooling for detecting a missing hole. Background Art
[0002] After some parts are cast, workers are required to drill a hole in the center. However, since the hole is located in the center of the casting, it is not easy for workers to tell whether a hole has been drilled. Therefore, missed holes often occur in the actual production process.
[0003] The existing inspection tooling currently uses the outer diameter of the part to determine whether the part's outer diameter is qualified. Therefore, it can only identify the external shape of the part, but cannot identify whether the part has been punched. As a result, unpunched parts often flow out and are delivered to customers, which ultimately causes customers to hit the tool when processing parts that have missed holes. Utility Model Content
[0004] The utility model aims to provide a missing hole inspection tool, by which the missing hole inspection tool can effectively detect whether the punching operation inside a part is completed.
[0005] In order to achieve the above-mentioned purpose, the utility model provides a missing hole inspection tool, which includes a tool body, a hole detection and an appearance detection located on the tool body, wherein the hole detection is arranged in the middle of the tool body and matches with the inner hole of the part, and the appearance detection surrounds the hole detection and matches with the appearance of the part;
[0006] The inner hole of the part is sleeved on the hole detection, and the outer surface of the part is in contact with the shape detection.
[0007] Preferably, a limiting mechanism for limiting the position of the parts is also provided on the tool body.
[0008] Preferably, the limiting mechanism is configured as a limiting block, and the limiting block cooperates with a notch on the outer surface of the part to limit the position of the part.
[0009] Preferably, the limiting mechanism is configured as a limiting hole, and the limiting hole cooperates with the protrusion of the part to limit the position of the part.
[0010] Preferably, the limiting mechanism is provided with a chamfer.
[0011] Preferably, the upper end surface of the hole detection is provided with a chamfer.
[0012] Preferably, the upper end of the shape detection is provided with a chamfer.
[0013] Preferably, the surface of the shape detection device that fits the part is set to a surface with a curvature consistent with the outer surface of the part.
[0014] Preferably, the connection surface between the hole detection and the shape detection is configured to match the bottom surface of the part.
[0015] According to the above technical solution, the utility model detects whether a part has been punched by placing the part into a missing hole inspection tool. If the part has completed the drilling process, then its inner hole can just match the hole detection, and its outer surface fits the shape detection, and the part can be smoothly placed in the missing hole inspection tool; but if the part is missing a hole, then when the part is placed on the missing hole inspection tool, its bottom surface will interfere with the hole detection, so that the part cannot be placed in the missing hole inspection tool. Therefore, the missing hole inspection tool can effectively monitor whether the part has completed the punching operation.
[0016] Preferably, the missing hole inspection tool is set in the next process of the punching process, so that the operator can effectively monitor whether the parts have inner holes through the tool. If it is found that the parts cannot be placed in the missing hole inspection tool due to interference with the hole detection, the operator can pick out these parts and send them back to the punching process for re-punching, thereby effectively preventing parts with unfinished punching operation from flowing out of the production line.
[0017] Other features and advantages of the present invention will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0030] In the present utility model, unless otherwise stated, directional words contained in terms such as "middle part, surrounding, outer surface, upper end face" merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.
[0031] See also Figure 1-5 The missing hole inspection tool comprises a tool body 1, a hole detection 2 and an appearance detection 3 located on the tool body 1, wherein the hole detection 2 is arranged in the middle of the tool body 1 and matches with the inner hole 102 of the part 10, and the appearance detection 3 surrounds the hole detection 2 and matches with the appearance of the part 10;
[0032] The inner hole 102 of the part 10 is sleeved on the hole detection 2 , and the outer surface of the part 10 is in contact with the shape detection 3 .
[0033] Through the implementation of the above technical solution, the part 10 is placed in the missing hole inspection tool. If the part 10 has completed the drilling process, then its inner hole 102 can just match the hole detection 2, and its outer surface is in line with the shape detection 3, and the part 10 can be smoothly placed in the missing hole inspection tool; but if the part 10 is missing a hole, then when the part 1 is placed on the missing hole inspection tool, its bottom surface will interfere with the hole detection 2, so that the part 10 cannot be placed in the missing hole inspection tool. Therefore, the missing hole inspection tool can effectively monitor whether the part 10 has completed the drilling operation.
[0034] Preferably, the missing hole inspection tool is set in the next process of the punching process, so that the operator can effectively monitor whether the part 10 has the inner hole 102 through the tool. If it is found that the part 10 cannot be placed in the missing hole inspection tool due to interference with the hole detection 2, the operator can pick out these parts 10 and send them back to the punching process for re-punching, thereby effectively preventing the parts 10 that have not completed the punching operation from flowing out of the production line.
[0035] In this embodiment, preferably, a limiting mechanism for limiting the position of the part 10 is also provided on the tool body 1 .
[0036] The part 10 is effectively limited under the action of the hole detection 2 and the shape detection 3, so that the part 10 and the tool body 1 only have the freedom of rotation. After the limit mechanism is set on the tool body 1, the part 10 can be further limited, so that the part 10 cannot rotate on the tool body 1. Therefore, the part 10 can be effectively fixed by the missing hole inspection tool, which is beneficial to the machining operation.
[0037] One limiting mechanism can be provided, and one limiting mechanism can limit the rotation of the part 10, or multiple limiting mechanisms can be provided, and multiple limiting mechanisms can improve the stress conditions of the missed hole inspection tooling and the part 10 at the position of the limiting mechanism during the machining process.
[0038] In this embodiment, preferably, the limiting mechanism is configured as a limiting block 4 , and the limiting block 4 cooperates with the notch 101 on the outer surface of the part 10 to limit the position of the part 10 .
[0039] If there is a notch on the surface of the part 10 and the notch 101 is deep, and the wall thickness on both sides of the notch 101 can meet the strength requirements of processing, the position of the part 10 can be limited by setting a limit block 4 to cooperate with the notch 101.
[0040] In this embodiment, preferably, the limiting mechanism is configured as a limiting hole, and the limiting hole cooperates with the protrusion of the part 10 to achieve position limitation of the part 10 .
[0041] If there is a protrusion on the surface of the part 10, and the protrusion's extended length and thickness can meet the processing requirements, the position of the part 10 can be limited by setting a limiting hole to cooperate with the protrusion.
[0042] In this embodiment, preferably, the limiting mechanism is provided with a chamfer.
[0043] The limit block 4 is provided with a chamfer, which is very suitable for the limit block 4 to cooperate with the notch 101 on the outer surface of the part 10, and is conducive to the limit block 4 extending into the notch 101. The chamfer has a guiding effect.
[0044] The limiting hole is provided with a chamfer, which is beneficial for the protrusion on the outer surface of the part 10 to extend into the limiting hole, and the chamfer has a guiding function.
[0045] In this embodiment, preferably, the upper end surface of the hole detection 2 is provided with a chamfer.
[0046] The upper end surface of the hole detection 2 is provided with a chamfer to facilitate the matching of the hole detection 2 with the inner hole 101.
[0047] In this embodiment, preferably, the upper end of the shape detection 3 is provided with a chamfer.
[0048] The upper end of the shape detection 3 is provided with a chamfer to facilitate the part 10 to be placed in the missing hole inspection tool.
[0049] In this embodiment, preferably, the surface of the shape detection 3 that fits the part 10 is set to be a surface with the same curvature as the outer surface of the part 10.
[0050] The surface of the shape detection 3 that fits the part 10 is set to be a surface with the same curvature as the outer surface of the part 10. By detecting whether the part 10 can be effectively placed, it can be detected whether the shape of the outer surface of the part 10 meets the requirements.
[0051] Preferably, after the part 10 is placed in the missing hole inspection tool, by using a feeler gauge to detect the gap between the part 10 and the shape detection 3, it can also be determined whether the outer surface shape of the part 10 meets the requirements.
[0052] In this embodiment, preferably, the connection surface 5 of the hole detection 2 and the shape detection 3 is configured to match the bottom surface of the part 10 .
[0053] The connection surface 5 cooperates with the bottom surface of the part 10 to support the part 10, so as to ensure the position stability and structural strength of the part 10 during the machining process.
[0054] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.
[0055] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
