[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Example

[0026] To address the issue of existing technologies relying on manual intervention, such as... Figure 1 The product shown is subjected to aperture detection, which is slow and prone to false positives and false negatives. (For reference...) Figures 2-4 As shown, this application discloses an inner diameter detection device, including a detection platform 10, a transport mechanism 20, and a detection mechanism 30. The transport mechanism 20 includes a telescopic platform 21 disposed on the detection platform 10 along a first direction and a transport fixture 22 disposed on the telescopic platform 21. The telescopic platform 21 is preferably designed as a servo-electric slide disposed above the detection platform 10 along the first direction. The transport fixture 22 specifically includes a base 221 fixed on the servo-electric slide, a product contouring groove 222 formed on the upper surface of the base 221, and several clearance holes 223 formed on the bottom wall of the product contouring groove 222 and corresponding to the product hole positions. Before performing the detection work, the operator will... Figure 1 The product shown is placed in the product contouring groove 222, and the base 221 is moved to the detection position by a servo electric slide.

[0027] The testing mechanism 30 includes a frame 31 erected above the testing platform 10 at the end of the telescopic platform 21, a circular groove 311 formed on the surface of the frame 31, a support 32 set above the surface of the frame 31 and facing the circular groove 311, a first inner diameter testing unit 33 set on the support 32 and passing through the circular groove 311, an automatic rotating platform 34 located at the bottom of the surface of the frame 31 and surrounding the circular groove 311, and a second inner diameter testing unit 35 and a third inner diameter testing unit 36 ​​respectively set at the bottom of the automatic rotating platform 34.

[0028] When the telescopic platform 21 drives the transport fixture 22 to the detection position, the detection part of the first inner diameter detection unit 33 is inserted into the center hole of the product and presses the entire product. During this process, the detection part of the first inner diameter detection unit 33 will automatically detect the inner diameter of the center hole of the product. After that, the automatic rotating platform 34 will drive the second inner diameter detection unit 35 and the third inner diameter detection unit 36 ​​to rotate. The second inner diameter detection unit 35 will detect the upper part of the hole diameter of the stepped hole of the product, and the third inner diameter detection unit 36 ​​will detect the lower part of the hole diameter of the stepped hole of the product.

[0029] Note that the product of this application has four stepped holes, which means that the automatic rotating platform 34 needs to drive the second inner diameter detection unit 35 and the third inner diameter detection unit 36 ​​to rotate and detect each stepped hole separately.

[0030] The following is a detailed structural description of the 30 components of the testing mechanism:

[0031] The first inner diameter detection unit 33 includes a first pneumatic slide 331 mounted on the bracket 32 ​​and a first inner diameter detection probe 332 mounted on the first pneumatic slide 331. When the telescopic platform 21 drives the transport fixture 22 to the detection position, the first pneumatic slide 331 drives the first inner diameter detection probe 332 to descend and insert the first inner diameter detection probe into the center hole of the product and press down on the entire product.

[0032] The automatic rotating platform 34 includes an annular guide rail 341 located on the periphery of the circular groove 311 and set at the bottom of the platform 31; a hollow disk 342 slidably connected to the annular guide rail 341; an annular rack 343 set on the outer periphery of the hollow disk 342; a mounting groove 312 opened on one side of the bottom of the detection platform 10; and a servo motor 344 set in the mounting groove 312 and mounted on its output shaft with a gear 345 meshing with the annular rack 343. When driving the second inner diameter detection unit 35 and the third inner diameter detection unit 36 ​​to rotate, the servo motor 344 drives the gear 345 to rotate, causing the annular rack 343 and the hollow disk 342 to rotate. Since the second inner diameter detection unit 35 and the third inner diameter detection unit 36 ​​are both set on the hollow disk 342, the above-mentioned purpose is achieved.

[0033] The second inner diameter detection unit 35 includes a second pneumatic slide 351 disposed on a hollow disk 342 and a second inner diameter detection probe 352 disposed on the second pneumatic slide 351. When detecting the inner diameter of the upper part of the product step hole, the second pneumatic slide 351 drives the second inner diameter detection probe to insert into the upper part of the product step hole.

[0034] The third inner diameter detection unit 36 ​​includes a third pneumatic slide 361 mounted on a hollow disk 342 and a third inner diameter detection probe 362 mounted on the third pneumatic slide 361. When detecting the inner diameter of the lower part of the product step hole, the third pneumatic slide 361 drives the third inner diameter detection probe 362 to insert into the lower part of the product step hole.

[0035] To facilitate operators in knowing whether the product inspection is qualified, this application also requires the design of a PLC controller (not shown in this application) to control the entire equipment, and the setting of an alarm (not shown in this application) connected to the PLC controller. If the data detected by the first inner diameter detection probe 332, the second inner diameter detection probe 352 and the third inner diameter detection probe 362 are unqualified, the PLC controller will control the alarm to sound an alarm.

[0036] Of course, any electrical components mentioned above are known technologies and can be readily obtained by those skilled in the art, so they will not be elaborated upon here.

[0037] In the description of this specification, the references to terms such as "an embodiment," "example," "specific example," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
