Description

Technical Field

[0001] This utility model relates to the field of rotor testing, and in particular to a rotor inner and outer diameter testing system. Background Technology

[0002] The final stage of rotor production requires the inspection of the rotor's inner and outer diameters; only those that pass the inspection are supplied. The current inspection method involves using separate gauges for the inner and outer diameters, with no interaction between the two results. If the outer diameter inspection passes first, the subsequent inner diameter inspection is relatively smooth. However, if either the outer or inner diameter fails, the failure often requires manual recording or labeling to facilitate correction and re-inspection, resulting in low efficiency.

[0003] In addition, the use of existing internal and external diameter gauges is likely to lead to detection errors due to operational mistakes. When re-inspection is required, the rotor still needs to be manually removed from the gauge and the inspection repeated, which is inconvenient and requires manual recording of the number of inspections, which also affects the inspection efficiency.

[0004] Chinese utility model patent with announcement number CN208818126U discloses a rotor inner and outer diameter gauge. Although it can detect the inner and outer diameters of the rotor at the same time, it still requires manual recording of the detection process. Furthermore, after the rotor detection is completed, a reset spring is set up to remove the rotor from the outer diameter detection column, which makes the structure complex and increases the detection cost.

Detailed Implementation

[0022] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, the rotor inner and outer diameter detection system proposed in this utility model transmits the detection results of the inner and outer diameters to the central control unit through the sensing unit. The central control unit determines whether the detection is passed according to the preset judgment strategy and transmits the result of the detection to the display unit. The display unit can show the test status to the tester through the corresponding indicator lights, so that the detection results of the inner and outer diameters can be recorded intuitively and continuously. When the detection result of the inner or outer diameter is unqualified, the tester can know it through the display unit. When retesting after correction, the corresponding item test can be performed according to the instructions of the display unit.

[0024] The pre-set judgment strategy can be that if the sensing unit fails to detect the rotor below the outer diameter detection component and the inner diameter detection component within a set time, it is judged as unqualified. At this time, the display unit will alarm the tester by means of indicator lights and / or audible and visual alarms. The tester can correct the corresponding inner and outer diameters and retest. The main control unit can record the number of tests. If it is still unqualified after the set number of tests, it may be marked as a defective product and will not be tested in the next item.

[0025] In this embodiment, the main control unit can be a single-chip microcomputer (PLC) or a PC; the sensing unit is located between the inner diameter detection component and the outer diameter detection component, and can detect whether there is a rotor below the outer diameter detection component and below the inner diameter detection component; the sensing component can be a diffuse reflection sensor; the display unit includes several indicator lights of the same or different colors and / or an audible and visual alarm. For example, a green indicator light is used for items that pass the test, while a red indicator light is used for items that fail the test. An audible and visual alarm can also be used in conjunction with the display unit.

[0026] Please refer to Figures 1 to 3The system includes a testing platform and an inner diameter testing component, an outer diameter testing component, and a control component disposed on the testing platform. The control component includes a main control unit, a sensing unit, and a display unit. The sensing unit and the display unit are connected to the main control unit. The sensing unit is disposed between the inner diameter testing component and the outer diameter testing component and is used to detect whether there is a rotor below the outer diameter testing component and below the inner diameter testing component. The display unit is used to indicate the testing results of the inner and outer diameters.

[0027] Please see Figure 2 and Figure 3 The outer diameter detection component 2 and inner diameter detection component 3 of this utility model have relatively simple structures and can also use existing structures. In this embodiment, the outer diameter detection component 2 and inner diameter detection component 3 are set on the detection platform 1. The outer diameter detection component 2 includes an outer diameter detection bracket 20 and an outer diameter detection platform 21 set above the outer diameter detection bracket 20. An outer diameter gauge 22 is set on the outer diameter detection platform 21. The detection range of the sensing unit 4 is located below the outer diameter detection platform 21. When performing outer diameter detection, the rotor is picked up and placed above the outer diameter gauge 22, allowing it to fall freely. If it passes through the outer diameter gauge 22 and falls below the outer diameter detection platform 21 within a set time, the sensing component 4 can detect the rotor, and the main control unit can display that the detection has passed through the display unit. Otherwise, it will display that the test has failed and issue an alarm to the tester.

[0028] like Figure 3 As shown, the inner diameter detection component 3 includes an inner diameter gauge 30 and a balance block 31 detachably mounted on the detection platform 1. The balance block 31 surrounds the inner diameter gauge, and its thickness is the same as the thickness of the protective ring on the bottom surface of the rotor 5 to be tested. That is, when the inner diameter of the rotor is to be tested, the central shaft hole of the rotor is aligned with the inner diameter gauge 30 and allowed to fall freely. If it falls and contacts the balance block 31, the rotor 5 to be tested will be in a horizontal state. At this time, the test is considered passed.

[0029] Furthermore, in order to facilitate the disengagement of the rotor 5 from the inner diameter detection assembly, the inner diameter detection assembly 3 also includes a lifting unit, which includes a lifting cylinder 32 and a lifting plate 33. The lifting plate 33 has a through hole for the inner diameter gauge 30 to pass through. At this time, the balance block 31 is set on the lifting plate 33. The lifting cylinder 32 is used to drive the rotor to be tested to move upward through the lifting plate to disengage from the inner diameter gauge.

[0030] Specifically, the inner diameter detection component 3 includes an inner diameter detection bracket 34, and a lifting cylinder 32 is mounted on the inner diameter detection bracket 34. The lifting cylinder 32 is a rodless cylinder. The lifting plate 33 is connected to the slide of the lifting cylinder 32. After the test is completed, the lifting cylinder drives the lifting plate to rise so that the rotor to be tested can be removed. The structure is simple and the operation is convenient.

[0031] In addition, the inner diameter detection component 3 also includes a protective enclosure 35, which is disposed on the detection table 1 and surrounds the inner diameter gauge 30 on the side away from the sensing unit 4. The protective enclosure prevents the rotor 5 under test from rolling off and does not affect the sensing capability of the sensing unit.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
