Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile rotor technology, and in particular to an automobile rotor coaxiality detection device. BACKGROUND

[0002] The automobile rotor (such as a driving motor rotor, a generator rotor, etc.) is a core rotating component of the automobile power system, and the manufacturing and assembly precision thereof directly affects the vibration, noise, efficiency and reliability of the whole vehicle. Among them, the coaxiality is one of the key geometric tolerances for measuring the quality of the rotor, which refers to the deviation degree of the axis of each key shaft section (such as the bearing section, the core section, etc.) of the rotor relative to the reference axis. If the coaxiality is out of tolerance, it will cause unbalanced force of the rotor during high-speed rotation, aggravate bearing wear, cause abnormal vibration and noise, and even cause safety accidents in severe cases.

[0003] At present, the detection of the automobile rotor coaxiality in the industry mainly relies on the following methods. The traditional contact type measurement method, such as the three-coordinate measuring machine (CMM), has high precision, but the detection speed is slow, and it needs to be operated in a constant temperature environment, mainly used for laboratory sampling inspection, and cannot meet the timeliness requirements of full inspection or high-frequency sampling inspection on the production line. For example, manual dial gauge measurement using a dial gauge, a percentage table, etc. relies heavily on the experience of the operator, has poor consistency, and is also inefficient. In addition, the detection dimension is single, and the information is not comprehensive. Such methods can only make qualitative judgments of "pass / fail" or obtain simple deviation values of limited sections, and it is difficult to comprehensively and accurately quantify the coaxiality error values and change trends in the full stroke range, which is not conducive to accurate process analysis and quality tracing. In view of the above problems, no effective solution has been proposed so far. SUMMARY

This solves the problems of traditional contact measurement methods, such as coordinate measuring machines (CMMs), which, while highly accurate, are slow and require constant temperature operation, making them mainly suitable for laboratory sampling and unable to meet the timeliness requirements of full inspection or high-frequency sampling on production lines; manual measurement using dial indicators or micrometers, which heavily relies on operator experience, has poor consistency, and is also inefficient; and the methods are limited in scope and information, often only providing qualitative "pass / fail" judgments or obtaining simple deviation values ​​for limited sections, making it difficult to comprehensively and accurately quantify the coaxiality error values ​​and trends across the entire travel range, which is not conducive to accurate process analysis and quality traceability.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0019] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0020] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-10 As shown, this application relates to a device for testing the coaxiality of an automobile rotor. Figures 1-2 As shown, the automotive rotor coaxiality testing equipment includes a housing 10. The housing 10 serves as the basic load-bearing structure for the entire coaxiality testing equipment, used for mounting, positioning, and supporting key functional modules including, but not limited to, a first support assembly 20, a first sliding assembly 30, a testing assembly, a rotating support assembly 60, and a floating assembly 70. This design enables good assembly results and ensures good fit between components.

[0023] Two sets of first support components 20 are disposed opposite to each other on both sides of the upper surface of the housing 10; the two sets of first support components 20 are symmetrically arranged on the left and right sides of the upper surface of the housing 10 to support and limit the movement direction of the first sliding component 30. This can form a stable linear support structure to ensure the straightness of the sliding component during movement; at the same time, the symmetrical arrangement can effectively counteract lateral forces and reduce the risk of sliding sway.

[0024] Of course, its structure can adopt a column type, frame type or guide rail support structure, and the parallelism of the two support components and the consistency of the coaxial reference are ensured through precision machining.

[0025] The first sliding component 30 is connected at both ends to two sets of the first support components 20. The first sliding component 30 typically includes a linear guide rail, a slider, and a drive unit, which can be a servo motor or a cylinder, used to drive the gripping component 40 to move along a preset linear trajectory above the housing 10. Its direction of movement forms a clear process logic relationship with the arrangement direction of the first detection component 50 and the rotating support component 60. This enables high-precision linear movement of the gripping component 40, ensuring the repeatability of detection points; simultaneously, it facilitates multi-station collaborative detection, improving the overall detection cycle time.

[0026] The gripping component 40 is connected to the first sliding component 30, and its output end faces the housing 10. The gripping component 40 is used to clamp, transport, and release the automobile rotor to be tested. Its output end faces the housing 10 to complete the precise transfer from material picking to the testing position. This avoids manual contact, reducing human error and safety risks. At the same time, it ensures the consistency of the rotor's posture during the transfer process, preventing testing errors caused by skewness. Furthermore, it improves testing efficiency and is suitable for online testing or sampling inspection scenarios on production lines.

[0027] It should be noted that the gripping component 40 may employ, but is not limited to, pneumatic grippers, electric grippers, or vacuum adsorption structures, and can be quickly replaced according to the rotor specifications.

[0028] Two first detection components 50 are disposed opposite to each other on the upper surface of the housing 10, and are located at least on the moving trajectory of the gripping component 40. The two first detection components 50 are symmetrically arranged on the upper surface of the housing 10 and on the moving path of the gripping component 40, for synchronous or sequential detection of the first detection points on both sides of the product to be inspected. This allows for the rapid acquisition of initial position data of the reference surfaces on both sides of the rotor, thereby providing a reference benchmark for subsequent multi-point coaxiality detection and improving overall detection accuracy. Simultaneously, the dual-sided detection structure can automatically determine whether the rotor has significant eccentricity or abnormal end-face runout.

[0029] Two rotating support assemblies 60 are disposed opposite to each other on the upper surface of the housing 10 and are parallel to the first detection assembly 50. The rotating support assemblies 60 are used to carry and support the rotor to be tested, enabling it to rotate freely or in a controlled manner around its own axis. Their structure may include, but is not limited to, V-shaped rollers, roller supports, or bearing-type rotating seats 602, and the axes of the two rotating support assemblies 60 are kept strictly parallel. This provides stable, low-resistance rotation conditions for the rotor, thereby ensuring that the rotor's rotation axis is consistent with the detection reference and avoiding false deviations.

[0030] A floating component 70 is disposed on the upper surface of the housing 10 and located on one side of the rotating support component 60. The floating component 70 is used to apply flexible driving or limiting action to the rotor after it is placed on the rotating support component 60, thereby guiding the rotor's directional rotation. This allows the rotor to make minute adaptive adjustments during rotation, eliminating clamping stress; it also avoids damage to the rotor surface or distortion of detection data caused by rigid driving, thus improving the stability and reliability of multi-point detection processes.

[0031] Of course, this component can be, but is not limited to, elastic pressure rollers, elastic support arms, or drive wheels with elastic compensation structures. The second detection component 80 is disposed adjacent to the rotating support component 60 on the upper surface of the housing 10, and located away from the first detection component 50. The second detection component 80 is used to perform multi-point dynamic detection on the specified circumferential outer surface of the rotor. It can move along a preset trajectory and collect radial data at multiple angles during rotor rotation. It can realize multi-point coaxiality detection, rather than single-point or single-section detection, thereby constructing a full circumferential coaxiality distribution curve of the rotor, improving the comprehensiveness of the detection data, and thus helping to discover local processing defects or assembly deviations.

[0032] The gripping component 40 grips and moves the product to be tested between the two first detection components 50, and the two first detection components 50 respectively detect the first detection points on both sides of the product to be tested; The gripping component 40 places the product to be tested on the two rotatable rotating support components 60. The floating component 70 drives the product to be tested to rotate in an orientation. The second detection component 80 performs multi-point detection of coaxiality on the designated circumferential outer surface of the product to be tested according to a preset movement trajectory, so as to detect the multi-point coaxiality of the automobile rotor.

[0033] Specifically, firstly, the gripping component 40 moves the rotor between the two first detection components 50 to complete the initial benchmark detection; secondly, the gripping component 40 places the rotor on the two rotating support components 60; then, the floating component 70 guides the rotor to rotate stably; next, the second detection component 80 performs coaxiality detection on multiple circumferential points of the rotor according to a preset trajectory; finally, by combining the multi-point detection data, the overall coaxiality evaluation result of the rotor is obtained.

[0034] As can be seen from the above description, this application achieves the following technical effects: In this embodiment, an automatic multi-point coaxiality detection method is adopted. The gripping component 40 grips and moves the product to be tested between the two first detection components 50. The two first detection components 50 respectively detect the first detection points on both sides of the product to be tested. The gripping component 40 places the product to be tested on the two rotatable rotating support components 60. The floating component 70 drives the product to be tested to rotate in an orientation. The second detection component 80 performs multi-point coaxiality detection on the designated circumferential outer surface of the product to be tested according to a preset movement trajectory, thereby detecting the multi-point coaxiality of the automobile rotor. This achieves the purpose of automatically detecting the multi-point coaxiality of the automobile rotor, thereby improving the detection accuracy and efficiency. This technology improves upon traditional contact measurement methods, such as coordinate measuring machines (CMMs), which, while highly accurate, are slow and require constant temperature operation, primarily used for laboratory sampling and unable to meet the timeliness requirements of full inspection or high-frequency sampling on production lines. Another example is manual measurement using dial indicators, which heavily relies on operator experience, suffers from poor consistency, and is also inefficient. Furthermore, these methods often only provide a single dimension of measurement and incomplete information, typically only allowing for qualitative "pass / fail" judgments or obtaining simple deviation values ​​for limited cross-sections. They struggle to comprehensively and accurately quantify the coaxiality error values ​​and trends across the entire travel range, hindering precise process analysis and quality traceability.

[0035] Furthermore, the first support assembly 20 includes two sets of upright, oppositely arranged support columns 201. A first fixing plate 202 is horizontally arranged on the top of each support column 201, and the first sliding assembly 30 is disposed on the first fixing plate 202. It is understood that the first support assembly 20 includes two sets of upright, oppositely arranged support columns 201, with the tops of the two sets of support columns 201 laterally connected by an integral or connecting fixing plate to form a stable portal or frame structure. The first sliding assembly 30 is mounted on this fixing plate, ensuring its motion reference is located within a uniform height plane at the top of the support columns 201. This forms a highly rigid spatial support frame, reducing vibration and swaying during sliding; simultaneously, it ensures the straightness of the first sliding assembly 30's motion trajectory, improving gripping and positioning accuracy.

[0036] like Figure 4As shown, the gripping component 40 includes: a first movable plate 401 disposed on the two first sliding components 30; a first driving component 402 horizontally disposed on the first movable plate 401; a second driving component 403 disposed at one end of the first movable plate 401 and connected to the top of the first support component 20; a third driving component 404 vertically disposed on the first driving component 402; a movable plate 405 disposed on the third driving component 404; an eighth driving component 406 disposed at the bottom of the movable plate 405; and arc-shaped grippers 407 disposed opposite to each other on the eighth driving component 406.

[0037] Specifically, the gripping component 40 includes a first movable plate 401 disposed on the first sliding component 30, a first driving component 402 horizontally disposed on the first movable plate 401 for lateral displacement; a second driving component 403 disposed at one end of the first movable plate 401 and connected to the top of the first support component 20 for forward and backward movement; a third driving component 404 vertically disposed on the first driving component 402 for vertical movement; the output end of the third driving component 404 is connected to a movable plate 405, an eighth driving component 406 disposed at the bottom of the movable plate 405, and arc-shaped grippers 407 disposed opposite to each other on the eighth driving component 406. This multi-degree-of-freedom gripping structure adapts to the automatic picking and placing of rotors of different sizes; simultaneously, the arc-shaped grippers disperse contact stress, preventing scratches on the rotor surface.

[0038] like Figure 3 As shown, the first detection component 50 includes: a guide shaft support 501 disposed on the upper surface of the housing 10, a guide rod 502 vertically disposed on the guide shaft support 501, and a linear displacement sensor 503 disposed on the guide rod 502. It can be understood that the first detection component 50 includes a guide shaft support 501 fixed to the upper surface of the housing 10, a guide rod 502 vertically disposed on the guide shaft support 501, and a linear displacement sensor 503 mounted on the guide rod 502. The linear displacement sensor 503 can perform minute displacement detection along the direction of the guide rod 502. The guide rod 502 defines the detection direction of the sensor to prevent lateral swaying; the linear displacement sensor 503 performs non-contact detection with the rotor surface to acquire radial or end-face displacement data; symmetrically arranged on both sides, it is used to simultaneously detect the reference points on both sides of the rotor.

[0039] like Figures 5-8As shown, the rotating support assembly 60 includes two opposing support seats 601. Two adjacent bearings 602 are respectively disposed on the inner side of each support seat 601 near its top. An arc-shaped groove 603 is formed on the top of each support seat 601 between the two bearings 602. This design ensures smooth and concentric rotation of the rotor; effectively avoids localized wear or vibration caused by point contact; and improves the rotational repeatability and data stability of the rotor during testing.

[0040] like Figures 5-8 As shown, the floating assembly 70 includes: two second sliding assemblies 701 connected to and parallel to the upper surface of the housing 10; a second moving plate 702 disposed above the two second sliding assemblies 701; two third sliding assemblies 703 disposed parallel to the upper surface of the second moving plate 702; movable seats 704 disposed on the two third sliding assemblies 703; a fourth drive assembly 705 disposed on the movable seat 704 with its output end facing the rotating support assembly 60; and a position elastic adjustment assembly 90 disposed at the output end of the fourth drive assembly 705. It can be understood that the fourth drive assembly 705 applies rotational or limiting driving force to the rotor; the floating structure allows the rotor to adaptively adjust its posture within a preset range. This avoids rotor axis misalignment caused by rigid clamping, thereby improving the self-alignment capability of the rotor during rotation, which is beneficial for obtaining accurate coaxiality data and avoiding clamping error interference.

[0041] like Figure 9As shown, the position elastic adjustment component 90 includes: a first connecting plate 901 connected to the output end of the fourth driving component 705; a fourth sliding component 902 disposed on the side of the first connecting plate 901 away from the fourth driving component 705; a second connecting plate 903 vertically disposed on the fourth sliding component 902; the two sides of the second connecting plate 903 connected to the first connecting plate 901 via first connecting members 904; a first elastic member 905 disposed on the first connecting member 904; a fifth sliding component 906 vertically disposed on the side of the second connecting plate 903 away from the fourth sliding component 902; a mounting plate 907 disposed on the fifth sliding component 906; the two sides of the mounting plate 907 connected to the second connecting plate 903 via second connecting members 908; a second elastic member 909 disposed on the second connecting member 908; and a snap-fit ​​connector 910 disposed on the side of the mounting plate 907 away from the fifth sliding component 906. It is understood that the position elastic adjustment assembly 90 is composed of a first connecting plate 901, a fourth sliding assembly 902, a second connecting plate 903, a first elastic element 905, a fifth sliding assembly 906, a mounting plate 907, a second elastic element 909, and a locking connector 910, forming a dual elastic compensation structure in both the longitudinal and transverse directions, thereby achieving the effect of position adjustment; the locking connector 910 contacts the rotor surface or drive components to achieve flexible force transmission. This improves the smoothness of the rotary drive.

[0042] Furthermore, a fifth drive assembly 911 is also provided on the upper surface of the second movable plate 702. The output end of the fifth drive assembly 911 is connected to the movable seat 704, and a hydraulic damper 912 facing the movable seat 704 is provided below the fifth drive assembly 911. It can be understood that the fifth drive assembly 911 is used to adjust the overall position of the movable seat 704; the hydraulic damper 912 provides damping buffer when the movable seat 704 moves quickly or stops; and can improve the smoothness and reliability of the overall machine operation.

[0043] like Figure 8As shown, the second detection component 80 includes: a second fixed plate 801 connected to the upper surface of the housing 10; a sixth drive component 802 disposed on the top of the fixed plate; a horizontally arranged moving rod 803 disposed at the output end of the sixth drive component 802; a U-shaped support frame 804 disposed at the end of the moving rod 803; and seventh drive components 805 horizontally disposed on both sides of the U-shaped support frame 804 away from the fourth drive component 705, with the output ends of the two seventh drive components 805 facing each other and each disposed with a displacement sensor 806 for detecting the arc portion of the outer surface of the rotor. It can be understood that the second detection component 80 includes a fixed plate, a sixth drive component 802, a moving rod 803, a U-shaped support frame 804, and two seventh drive components 805. The two seventh drive components 805 respectively drive the displacement sensors 806 for detecting the arc portion of the outer surface of the rotor; it can achieve multi-point, multi-circumferential coaxiality detection; and at the same time, it can improve the spatial coverage of the detection data.

[0044] Furthermore, a through hole 101 is provided on the top of the housing 10, and a positioning tray mechanism 102 adjacent to the first detection component 50 is provided in the through hole 101.

[0045] Specifically, the positioning tray mechanism 102 includes: a frame at least partially disposed within the housing 10, a horizontal plate disposed on the top of the frame, a lifting cylinder vertically disposed within the frame, a tray disposed at the output end of the lifting cylinder opposite to the horizontal plate, and a plurality of limiting posts and positioning posts disposed on the tray. The positioning tray mechanism 102 is used for initial placement and positioning of the rotor, which can reduce the adjustment time of the gripping component 40 and improve the detection cycle time.

[0046] This application also has the following beneficial effects: 1. This application enables high-efficiency production, automated loading and unloading, and parallel multi-station testing.

[0047] 2. The application achieves high precision and high repeatability. The combination of full closed-loop motion control, precision mechanical structure and high-precision sensor eliminates human interference, and the measurement results are objective and reliable.

[0048] 3. The application enables comprehensive testing, combining rapid testing of key points with full testing of the entire functional surface, resulting in more complete testing information and stricter quality control.

[0049] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
