[0002] In modern industrial production, straightness measurement of shaft parts is crucial to ensuring product quality and performance. Traditional measuring equipment usually uses fixed fixtures to fix shaft parts, and then uses laser displacement sensors or other optical measuring tools to perform straightness detection. However, this traditional method has many shortcomings. First, when manually placing shaft parts in a fixed fixture, it is difficult to ensure that the center of the part is precisely aligned with the center of the fixture. This clamping offset will cause measurement errors and reduce measurement accuracy. Secondly, the size of traditional fixtures is fixed and cannot adapt to shaft parts of different diameters. Therefore, when measuring parts of different sizes, the fixture needs to be replaced frequently, which not only increases the complexity of the operation, but also significantly reduces measurement efficiency. In addition, traditional measuring equipment lacks intelligent data processing and fault diagnosis functions, and cannot monitor abnormal conditions during the measurement process in real time.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Please see the attached Figure 1 - Attachment Figure 9 An embodiment of the present invention provides an online straightness measurement device for shaft parts with an adaptive clamping function, including a mounting frame 1, a fixed box 801 is installed on the front side of the top of the mounting frame 1, an electric telescopic rod 802 is installed on the outside of the fixed box 801, the output end of the electric telescopic rod 802 is fixedly connected to a moving block 2 803, the top of the moving block 2 803 is fixedly connected to a connecting plate 804, and the left and right through-holes on the top of the fixed box 801 are slidably connected to moving rods 805, a plurality of mounting grooves are provided on the upper side of the inner part of the moving rod 805, the interior of the mounting groove is elastically connected to an arc plate 808 by a spring 2 807, and the outer side of the arc plate 808 is fixedly connected to an abutment plate 806, the top rear side of the mounting frame 1 is fixedly connected to a mounting plate 4, and an adaptive clamping component is installed on the outer side of the mounting plate 4, and the adaptive clamping component is used to clamp the part 7 to be measured.

[0034] Specifically, the mounting frame 1 serves as the supporting framework for the entire device, supporting all components and ensuring structural stability and operational precision. The fixed box 801 secures the electric telescopic rod 802 and other related components, providing a mounting base for the centering assembly. The electric telescopic rod 802 is mounted on the outside of the fixed box 801. Its telescopic motion drives the second movable block 803, enabling horizontal movement of the centering assembly and providing power for the centering operation. The movable rod 805 is slidably connected to the left and right through-holes on the top of the fixed box 801. Its upper interior features multiple mounting slots for mounting the curved plate 808 and the abutment plate 806, enabling up and down movement to achieve centering. The mounting slots, located on the upper interior of the movable rod 805, accommodate the curved plate 808 and the second spring 807, providing mounting and movement space for the abutment plate 806. The second spring 807 is resiliently connected within the mounting slots, providing elastic support for the curved plate 808 and ensuring close contact between the abutment plate 806 and the inner wall of the mounting hole of the part 7 to be measured, achieving precise centering. The adaptive clamping assembly is mounted on the outside of the mounting plate 4 and is used to clamp the part to be measured 7. Through its internal mechanical structure, it can automatically adjust the clamping force and position to adapt to shaft parts of different sizes and ensure the stability of the part during the measurement process.

[0035] The part 7 to be measured is placed above the mounting frame 1, the electric telescopic rod 802 is in a retracted state, and the moving block 2 803 and the connecting plate 804 are in their initial positions. The electric telescopic rod 802 is started, and its output end drives the moving block 2 803 to move horizontally along the outside of the fixed box 801. The movement of the moving block 2 803 drives the connecting plate 804 to move synchronously. Since the upper surface of the connecting plate 804 is designed as an inclined surface, its movement will push the moving rod 805 to move upward. When the moving rod 805 moves upward, the curved plate 808 and the abutment plate 806 inside it also rise. When the abutment plate 806 contacts the mounting hole at the bottom of the part 7 to be measured, due to the curved surface design of its outer surface, the abutment plate 806 will retract into the mounting groove, causing the spring 2 807 to be compressed. When the abutment plate 806 completely enters the mounting hole, under the elastic force of spring 2 807, the abutment plate 806 tightly contacts the inner wall of the mounting hole, achieving precise alignment and ensuring that the center of the part 7 to be measured is completely aligned with the center of the clamping device.

[0036] A driving motor 501 is installed on the outside of the mounting plate 4, and the output end of the driving motor 501 is fixedly connected to a driving screw 502. The outer surface of the driving screw 502 is threadedly connected to two threaded sleeves, and the outer surface of the threaded sleeve is fixedly connected to a moving plate 503. The outer surface of the moving plate 503 is provided with multiple arc surfaces.

[0037] Specifically, the drive motor 501 is activated, and its output drives the drive screw 502 to rotate. The rotation of the drive screw 502, through threaded engagement, causes the threaded sleeve to move axially along the drive screw 502. The direction of movement of the threaded sleeve is determined by the rotation direction of the drive motor 501. This movement of the threaded sleeve synchronously drives the movable plate 503 fixed to its outer surface.

[0038] The adaptive clamping assembly includes a mounting base 601 fixedly connected to the outside of the mounting plate 4. A guide rod 606 is fixedly connected to the inside of the mounting base 601. A spring 1 608 is sleeved on the outside of the guide rod 606. A guide block 607 is slidably connected to the outside of the guide rod 606. A moving block 1 603 is fixedly connected to the top of the guide block 607. Multiple support plates 609 are fixedly connected to the top of the mounting frame 1. A swing rod 602 is rotatably mounted on the inside of the support plates 609. Clamping wheels 1 604 are mounted on both ends of the swing rod 602. Clamping wheels 2 605 are mounted on the outside of the moving block 1 603. One end of the spring 1 608 is fixedly connected to the outside of the guide block 607, and the other end of the spring 1 608 is fixedly connected to the inside of the mounting base 601. The outer surface of the abutment plate 806 is configured as a curved surface, and the outer side of the curved plate 808 is slidably connected to the inner wall of the mounting groove.

[0039] Specifically, the guide rod 606 is used to guide the sliding movement of the guide block 607 to ensure the linearity and stability of the movement. Spring 1 608 is sleeved on the outside of the guide rod 606, with one end fixedly connected to the outside of the guide block 607 and the other end fixedly connected to the inside of the mounting seat 601. Spring 1 608 provides elastic force to ensure that the guide block 607 and the moving block 1 603 can move and reset flexibly. The guide block 607 moves in a straight line under the guidance of the guide rod 606 to ensure the accuracy of the clamping action. The support plate 609 is used to support the swing rod 602 to ensure the stable rotation of the swing rod 602. The swing of the swing rod 602 drives the clamping wheel 1 604 to approach or move away from the part 7 to be measured, thereby realizing the clamping or release operation.

[0040] The part 7 to be measured has been centered by the centering assembly, with its center aligned with the center of the clamping device. The adaptive clamping assembly is in its initial position, spring 1 608 is in its neutral state, and clamping wheel 1 604 and clamping wheel 2 605 are in their released states.

[0041] The movement of the movable plate 503 drives the movable block 1 603 to move along its curved surface. The movement of the movable block 1 603 is carried out under the guidance of the guide rod 606 through the guide block 607, ensuring the linearity and stability of the movement. During the movement of the movable block 1 603, the spring 1 608 provides elastic force to ensure that the guide block 607 can move flexibly and reset. The elastic force of the spring 1 608 can also absorb part of the impact force, ensuring the smoothness of the clamping process. The movement of the movable block 1 603 drives the clamping wheel 2 605 to approach the part 7 to be measured. At the same time, the swing rod 602 swings under the push of the movable block 1 603, so that the clamping wheel 1 604 also approaches the part 7 to be measured. Finally, the clamping wheel 1 604 and the clamping wheel 2 605 are tightly pressed against the outer surface of the part 7 to be measured, achieving a stable clamping effect. When the clamping operation is completed, the drive motor 501 stops rotating, and the threaded sleeve and the movable plate 503 remain in the current position to ensure the stability of the clamping state. At this point, the part 7 to be measured is securely clamped, providing stable support for subsequent straightness measurements. When the measurement is complete, the drive motor 501 rotates in the reverse direction, driving the drive screw 502 in the reverse direction. The threaded sleeve moves in the reverse direction along the axial direction of the drive screw 502, which in turn drives the movable plate 503 in the reverse direction. The reverse movement of the movable plate 503 drives the movable block 1 603 in the reverse direction, moving the clamping wheel 2 605 away from the part 7 to be measured. Simultaneously, the swing arm 602 swings in the reverse direction, moving the clamping wheel 1 604 away from the part 7 to be measured, completing the release operation.

[0042] The outer side of the moving block 1 603 is provided with two inclined surfaces, and one of the clamping wheels 1 604 is slidably connected to the outer surface of the inclined surfaces.

[0043] The top rear side of the mounting frame 1 is fixedly connected to a support frame 2. A laser displacement measuring device 3 is mounted on the bottom of the support frame 2. A mounting rail 10 is mounted on the top front side of the mounting frame 1. A manipulator 9 is mounted on the top of the mounting rail 10. The laser displacement measuring device 3 is controlled by a measurement system. A roller is provided at the bottom end of the movable rod 805. The top surface of the connecting plate 804 is configured as an inclined surface, and the roller contacts the outer surface of the inclined surface.

[0044] Specifically, after the manipulator 9 places the part 7 to be measured at the measuring position, the laser displacement measuring device 3 is started through the measuring system to start the straightness measurement of the part 7 to be measured.

[0045] Laser displacement measurement device 3 emits a laser beam and receives reflected light, collecting displacement data on the part's surface. The measurement system processes and analyzes this data through a multi-dimensional data acquisition module, an intelligent data processing and analysis module, an intelligent fault diagnosis and self-repair module, and a data security and encryption module, ultimately calculating the straightness error. After measurement is complete, robot arm 9 removes part 7 to be measured, and the device returns to its initial state, ready for the next measurement.

[0046] The measurement system includes the following modules:

[0047] A multi-dimensional data acquisition module is used to collect multi-dimensional data of the laser displacement measurement device 3, including displacement, reflected light intensity, ambient light interference, etc., to improve measurement accuracy and reliability;

[0048] Intelligent data processing and analysis module uses data processing algorithms and machine learning technology to analyze the collected multi-dimensional data, extract features, fit axes, and calculate straightness errors;

[0049] Among them: Data preprocessing is the first step of data processing, which usually includes operations such as noise removal and normalization. Assume that the collected displacement data is ,in Indicates the The displacement value of each measuring point, is the total number of measurement points. Its formula is as follows:

[0050] in: is the normalized data. is the minimum value among all the measured data. is the maximum value among all the measured data.

[0051] Intelligent fault diagnosis and self-repair module monitors the operating status of the measurement system in real time, automatically diagnoses faults and attempts self-repair to reduce downtime;

[0052] The data security and encryption module is used to ensure the security and integrity of measurement data and supports data encryption and remote transmission.

[0053] Specifically, the intelligent fault diagnosis and self-repair module and the data security and encryption module are crucial components of modern measurement systems. The module improves equipment reliability and operational efficiency through real-time monitoring and automatic repair capabilities. The data security and encryption module ensures the security and integrity of measurement data through encryption and integrity verification technologies. Together, these two modules provide a strong guarantee for the efficient and stable operation of online straightness measurement equipment for shaft parts.

[0054] Working principle: When using this device, it includes the following steps:

[0055] Parts grabbing and initial positioning: Through the cooperation of the manipulator 9 and the mounting guide rail 10, the shaft part 7 to be measured is accurately grabbed and placed above the mounting frame 1, preparing for subsequent measurement operations and ensuring that the part is in the appropriate initial position.

[0056] Centering process: Start the electric telescopic rod 802 to drive the moving block 2 803 to move along the outside of the fixed box 801. While the moving block 2 803 moves, the connecting plate 804 fixedly connected to it moves synchronously. Since the upper surface of the connecting plate 804 is designed to be an inclined surface, its movement will drive the moving rod 805 to move upward. At this time, the abutment plate 806 first contacts the mounting hole at the bottom of the part to be measured 7. The outer surface of the abutment plate 806 is designed as an arc surface. When it contacts the mounting hole, it will retract into the mounting groove, causing the spring 2 807 to be in a compressed state. After the abutment plate 806 completely enters the mounting hole, under the elastic force of the spring 2 807, the abutment plate 806 tightly contacts the inner wall of the mounting hole, realizing the centering process, so that the center of the part to be measured 7 is completely aligned with the center of the adaptive clamping assembly, thereby ensuring the stability of the part during the measurement process and the reliability of the measurement data.

[0057] Clamping operation: After the centering is completed, start the drive motor 501 to drive the drive screw 502 to rotate. The rotation of the drive screw 502 causes the threaded sleeve to move along its outer surface, thereby driving the movable plate 503 to move synchronously. The movement of the movable plate 503 prompts the movable block 1 603 to move along its arc surface. While the movable block 1 603 moves, the guide block 607 moves along the outer surface of the guide rod 606 and compresses the spring 1 608. As the movable block 1 603 continues to move, the swing rod 602 is driven to swing. The swinging of the swing rod 602 causes the clamping wheel 1 604 and the clamping wheel 2 605 to press tightly against the outer surface of the part 7 to be measured, achieving a stable clamping effect, ensuring that the part always remains stable during the measurement process, and avoiding measurement errors caused by improper clamping.

[0058] Straightness Measurement: After completing the aforementioned alignment and clamping operations, the measurement system begins operation. Supported by the support frame 2, the laser displacement measuring device 3 performs straightness measurements on the stably clamped part 7 to be measured. The measurement system utilizes its multi-dimensional data acquisition module, intelligent data processing and analysis module, intelligent fault diagnosis and self-repair module, and data security and encryption module to accurately collect measurement data, efficiently process and analyze data, monitor system operation status in real time, and ensure data security, ultimately producing accurate and reliable straightness measurement results.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
