[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0034] Example
[0035] See Figure 2 and Figure 3 This embodiment discloses a detection device for a symmetrical conical hole group of 12, used for detection. Figure 1 A specific part 10 of the part shown, wherein, as Figure 1As shown, the specific part 10 structure includes two spaced support ears 11 and two tapered holes 12 respectively provided on the two support ears 11, and the two tapered holes 12 are arranged opposite to each other. The detection device detects the parameters of the two tapered holes 12 on the specific part 10 of the part, including whether the taper of the two tapered holes 12 meets the design requirements, and whether the coaxiality of the two tapered holes 12 meets the design requirements.
[0036] Specifically, the testing device includes a support member 20 and a testing member 30. The support member 20 and the testing member 30 are detachably connected. During testing, the coaxiality of the two conical holes 12 is tested by using the coaxiality of the testing member 30 after it is connected to the support member 20, and the taper of the conical holes 12 is tested by using the testing surface 32 on the testing member 30.
[0037] The structure of the detection device will be described in detail below.
[0038] A connecting hole 21 is provided in the middle of both sides of the support member 20. The two connecting holes 21 are located on the same straight line. If the two connecting holes 21 are circular holes, the two connecting holes 21 are coaxially arranged. It should be understood that the structure of the connecting hole 21 in this application is not limited to circular holes, but can also be polygonal holes.
[0039] like Figure 6 As shown, the detection device includes two identical detection elements 30, and the two detection elements 30 are detachably connected to two connection holes 21 on both sides of the support member 20. Generally, during connection, the connecting part 31 on the detection element 30 is simply inserted into the connection hole 21 on the support member 20.
[0040] Since it is necessary to test the coaxiality of the two conical holes 12, when manufacturing the connecting part 31 of the testing part 30 and the connecting hole 21 of the support part 20, it is necessary to ensure the size of the connecting part 31 and the size of the connecting hole 21 to avoid large dimensional errors that could cause the connecting part 31 to wobble in the connecting hole 21, thereby affecting the accuracy of testing the two conical holes 12.
[0041] The inspection piece 30 has an inspection surface 32, which is a conical structure, and the taper of the inspection surface 32 is the same as the taper of the conical hole 12 when the part was designed, that is, the same as the taper of the standard conical hole 12.
[0042] After the two connecting holes 21 on the support member 20 and the connecting part 31 on the detection member 30 are all machined correctly, the support member 20 is first placed between the two support ears 11, and then the two detection members 30 are passed through the two tapered holes 12 so that they mate with the support member 20. If the two detection members 30 can mate with the two connecting holes 21, it indicates that the coaxiality of the two tapered holes 12 is within the design error range. If either detection member 30 cannot mate with the connecting hole 21, it indicates that the coaxiality of the two tapered holes 12 exceeds the design error range, indicating that the machining of the two tapered holes 12 does not meet the requirements.
[0043] When the coaxiality of the two tapered holes 12 meets the requirements, the detection surfaces 32 on the two detection pieces 30 can fit against the inner surfaces of the two tapered holes 12, indicating that the taper of the two tapered holes 12 meets the design tolerance. If a large gap appears between the inner surface of any tapered hole 12 and the detection surface 32 of the detection piece 30, it indicates that the machining of that tapered hole 12 does not meet the requirements. Alternatively, if the detection piece 30 cannot be inserted into any tapered hole 12, it also indicates that the machining of that tapered hole 12 does not meet the requirements.
[0044] This technical solution enables rapid detection of the taper of the tapered hole 12 and the coaxiality of two relatively arranged tapered holes 12, greatly improving the machining efficiency of the part. Furthermore, since this specific part 10 is a crucial feature of the part, it can be machined first during the overall part machining process. After machining, the machine tool can be stopped immediately, and the completed tapered hole 12 can be inspected using this detection device. Once it meets design requirements, the machine tool can be restarted to machine other features of the part. This method allows for inspection of the specific part 10 without removing the part, reducing the number of times the part needs to be clamped, thereby improving machining efficiency and avoiding clamping errors caused by multiple clamping operations.
[0045] In one specific embodiment:
[0046] See Figure 4 The testing device also includes multiple light-emitting elements 22, all of which are mounted on the support member 20. During the testing process, the light emitted by the light-emitting elements 22 is used to detect the fit between the testing surface 32 and the inner surface of the conical hole 12. If light leakage is detected, it indicates that the processing accuracy is insufficient.
[0047] Specifically, multiple light-emitting elements 22 are evenly distributed around the two connecting holes 21 on both sides of the support 20. Generally, the light-emitting elements 22 are LED beads, and the color of the light emitted by the LED beads can be a relatively obvious color, such as red.
[0048] In order to prevent the light from the light-emitting element 22 from leaking out and affecting the judgment of the conical hole 12, the thickness of the support member 20 is made the same as the distance between the two support ears 11 during the design process.
[0049] In another specific embodiment:
[0050] See Figure 3 The detection component 30 also includes a detection section and a support section 33. The detection surface 32 is located on the outer surface of the detection section. The support section 33 is cylindrical and has a convex lens 34. By providing the convex lens 34, the mating position between the detection surface 32 and the surface of the conical hole 12 can be magnified to facilitate observation of the mating state. Simultaneously, it works in conjunction with the light-emitting element 22 for detection. Generally, a small amount of light passes through the mating surface between the detection surface 32 and the surface of the conical hole 12, making direct observation difficult. However, with the aid of the convex lens 34, observation can be made more convenient.
[0051] In another specific embodiment:
[0052] The convex lens 34 has a ring structure and is set at an angle, with the angle of inclination being the same as the taper of the detection surface 32. By designing the convex lens 34 as a ring, it is possible to observe the mating surface of the detection surface 32 and the conical hole 12 from all directions. By designing the convex lens 34 at an angle, it is possible to view the mating surface of the detection surface 32 and the conical hole 12 through the middle of the convex lens 34.
[0053] In another specific embodiment:
[0054] In this application, the connecting hole 21 has a polygonal structure, such as the common quadrilateral and hexagon. Correspondingly, the connecting part 31 on the detection component 30 also has a polygonal cylindrical structure.
[0055] Through this embodiment, the support member 20 and the connector can be driven to rotate synchronously within the conical hole 12, thereby detecting the roundness and smoothness of the inner surface of the conical hole 12 and ensuring that the conical hole 12 meets more design requirements.
[0056] In another specific embodiment:
[0057] See Figure 5 The support member 20 is cylindrical, and its circular shape facilitates rotation. The support member 20 has a hollow interior, housing a battery 23 and a switch, both of which are connected to the light-emitting element 22. The battery 23 supplies power to the light-emitting element 22, and the switch controls its operation.
[0058] Preferably, the support member 20 is provided with multiple batteries 23, and all the batteries 23 are evenly distributed around the axis of the support member 20. Through this technical solution, the center of gravity of the support member 20 can be balanced so that its center of gravity is located on its circumference.
[0059] In another preferred embodiment, a ring-shaped cover plate 24 is provided on one side of the support member 20.
[0060] In another preferred embodiment, both the outer peripheral surface of the support member 20 and the outer peripheral surface of the support portion 33 of the detection member 30 have anti-slip structures. There is a gap between the anti-slip structure on the detection member 30 and the detection surface 32. The detection surface 32 is a smooth surface structure. By designing the anti-slip structure, it is convenient to manually drive the support member 20 and the detection member 30 to rotate.
[0061] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
