Description

Technical Field

[0001] This utility model belongs to the technical field of rotor core inner diameter counterbore testing mechanism, specifically relating to a rotor core inner diameter counterbore testing mechanism. Background Technology

[0002] The rotor core inner diameter countersunk hole inspection mechanism is a specialized device for inspecting the countersunk holes machined on the inner diameter surface of rotor cores. It typically consists of a positioning and fixing assembly, a detection sensing system, a transmission and adjustment mechanism, and a data processing unit. Its working principle is to securely clamp the rotor core through the positioning assembly, and drive the detection sensor to move along the inner diameter through the transmission mechanism to accurately collect key parameters such as the size, depth, and positional tolerance of the countersunk hole. The data processing unit then analyzes and judges whether these parameters meet the design standards, ultimately achieving rapid and accurate inspection of the countersunk hole machining quality to ensure the assembly accuracy and subsequent performance of the rotor core.

[0003] Because visual inspection alone is insufficient for fully verifying the countersunk hole diameter of the rotor core, the accuracy is too low and the efficiency is too slow. Therefore, it was decided to design a rotor core countersunk hole inspection mechanism to more accurately and quickly identify defective products, thus solving the current problems. Utility Model Content

[0004] The purpose of this invention is to provide a rotor core inner diameter countersunk hole inspection mechanism to address the problem mentioned in the background art, where relying solely on visual inspection to confirm the countersunk hole diameter of the rotor core results in low accuracy and slow efficiency. Therefore, it was decided to design a rotor core inner diameter countersunk hole inspection mechanism that can more accurately and quickly identify defective products, thus solving the current problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotor core inner diameter counterbore detection mechanism, comprising a base plate, a manual reversing valve installed at the upper left position of the base plate, a positioning fixture installed at the middle position of the upper end of the base plate, a rotor body installed at the upper end of the positioning fixture, a detection fixture installed at the upper end of the rotor body, a pen-shaped cylinder installed at the upper end of the detection fixture, a mounting plate installed at the rear position of the upper end of the base plate, an alarm light support column installed at the right position of the upper end of the base plate, an alarm light body installed at the upper end of the alarm light support column, a contact sensor installed at the inner side of the lower end of the base plate, a connecting rod fixed at the lower end of the base plate, a snap-fit ​​plate fixed at the lower end of the connecting rod, and a connecting plate installed at the lower end of the base plate via the snap-fit ​​plate and the connecting rod.

[0006] Preferably, the rotor body is placed on the inner side of the positioning fixture.

[0007] Preferably, the manual reversing valve is vented manually.

[0008] Preferably, the pen-shaped cylinder is used to drive the detection fixture at the lower end position to move, and the downward movement of the detection fixture detects the inner diameter hole of the rotor body.

[0009] Preferably, the detection fixture will touch the contact sensor when it enters the inner diameter hole of the rotor body.

[0010] Preferably, the alarm light support column is installed at the upper end of the base plate to support the alarm light body.

[0011] Preferably, the upper end of the connecting plate is provided with a through hole and a sliding groove, and the snap-fit ​​plate is sleeved inside the sliding groove.

[0012] Preferably, the connecting plate can rotate around the snap-fit ​​plate as its central axis, and the connecting plate can move outward through the sliding groove.

[0013] Compared with the prior art, this utility model provides a rotor core inner diameter countersunk hole detection mechanism, which has the following beneficial effects:

[0014] In use, place the base plate on any workbench, then place the rotor into the positioning fixture. Operate the manual reversing valve to allow air flow, and the pen-shaped cylinder will move the detection fixture downwards to inspect the inner diameter countersunk hole of the rotor. If the detection fixture passes the rotor's inner diameter, it will touch the contact sensor, which will send a signal to the alarm light to trigger an alarm indicating that the product is defective. Otherwise, the product is qualified. Then, operate the manual reversing valve to stop the air flow, and the pen-shaped cylinder will return to its original position. This adds a defective product alarm function to the overall structure, reducing the risk of misjudgment due to operator fatigue. Furthermore, this device can more quickly and accurately detect the inner diameter countersunk hole of the rotor core, effectively improving production efficiency and preventing the outflow of defective products.

[0015] The base plate of this device is mounted on the upper part of the table via a connecting plate at the lower end. The connecting plate can rotate around a circular snap-fit ​​plate as its central axis. The connecting plate can also move via a sliding groove. This multi-angle adjustment method facilitates alignment with external mounting holes through the circular holes, thus adapting to different installation environments. Attached Figure Description

A rotor body 10 is installed on the upper end of the positioning fixture 7. A detection fixture 5 is installed on the upper end of the rotor body 10. A pen-shaped cylinder 2 is installed on the upper end of the detection fixture 5. A mounting plate 4 is installed on the upper rear side of the base plate 1. An alarm light support column 9 is installed on the upper right side of the base plate 1. An alarm light body 8 is installed on the upper end of the alarm light support column 9. A contact sensor 3 is installed on the lower inner side of the base plate 1. A connecting rod 15 is fixed on the lower end of the base plate 1. A snap-fit ​​plate 14 is fixed on the lower end of the connecting rod 15. A connecting plate 11 is installed on the lower end of the base plate 1 through the snap-fit ​​plate 14 and the connecting rod 15.

[0025] Place the base plate 1 on any workbench as a basic support; then, place the rotor into the positioning fixture 7, ensuring the rotor is in the correct testing position; next, operate the manual reversing valve 6 to allow air flow, at which point the pen-shaped cylinder will drive the testing fixture 5 downwards to test the countersunk hole in the rotor's inner diameter; during the testing process, if the testing fixture 5 can pass through the rotor's inner diameter and touch the contact sensor 3, the contact sensor 3 will immediately send a signal to the alarm light, triggering an alarm to indicate that the product is defective; conversely, if the testing fixture 5 cannot pass through the rotor's inner diameter, it indicates that the product is qualified, and the alarm light will not be triggered; after the test is completed, operate the manual reversing valve 6 again to stop the air flow, and the pen-shaped cylinder will drive the testing fixture 5 back to its original position, preparing for the next test.

[0026] like Figure 1 and Figure 2 As shown, the rotor body 10 is placed inside the positioning fixture 7. The manual reversing valve 6 is manually controlled for ventilation. The pen-shaped cylinder 2 is used to drive the detection fixture 5 at the lower end to move. The downward movement of the detection fixture 5 detects the inner diameter hole of the rotor body 10. When the detection fixture 5 enters the inner diameter hole of the rotor body 10, it will touch the contact sensor 3. The alarm light support column 9 is installed at the upper end of the base plate 1 to support the alarm light body 8. The upper end of the connecting plate 11 is provided with a through hole 12 and a slide groove 13. The snap-fit ​​plate 14 is sleeved inside the slide groove 13.

The regular design of the positioning fixture 7 ensures the consistency of the rotor position during each test. The stable driving force of the pen-shaped cylinder makes the downward movement of the detection fixture 5 uniform and controllable. The sensitive triggering mechanism of the contact sensor 3 and the instant response of the alarm light form a rapid judgment link. The convenient operation of the manual reversing valve 6 makes the start and stop of the entire pneumatic process more flexible.
