[0034] The comprehensive inspection fixture for shafts provided in this embodiment can automatically adjust the clamping force according to the size and shape of the shaft through the floating device 5, so that the shaft is always in a suitable clamping state during the inspection process, and at the same time, it can reduce damage to the shaft caused by improper clamping; wherein, the two half-chucks 6 are arranged on the connecting plate 7 for relative or opposite reciprocating movement, and can be adaptively adjusted according to the diameter of the shaft to achieve reliable clamping of shafts of different diameters, thereby improving the versatility of the inspection fixture; the base 8 carries the connecting rope 10, the connecting plate 7, the weight block 9 and the two half-chucks 6 to reciprocate along the Y-axis on the workbench 1, and can be adaptively adjusted according to the position of the shaft, so that the half-chuck 6 can better cooperate with the shaft, thereby improving the accuracy and reliability of clamping; the two ends of the connecting rope 10 respectively pull the connecting plate 7 and the weight block 9, and the connecting plate 7 and the weight block 9 respectively move in the direction of the connecting force of the connecting rope 10 until they are balanced, which can provide a uniform and stable clamping force for the half-chuck 6, prevent the shaft from loosening or displacement during the inspection process, and ensure the accuracy of the inspection results.

[0035] Preferably, a driver 22 is fixed to the connecting plate 7. The driver 22 may be composed of a double-piston cylinder. The two working ends of the driver 22, which move toward or away from each other, are respectively connected to the two half-chucks 6. The driver 22 drives the two half-chucks 6 to reciprocate toward or away from each other. By driving the two half-chucks 6 to reciprocate toward or away from each other by the driver 22, the clamping of the shaft head is automated, labor is saved, and work efficiency and effectiveness are improved.

[0036] Preferably, the base 8 and the connecting plate 7 are connected by a sliding assembly 18, which is used to guide the sliding of the connecting plate 7. The sliding assembly 18 guides the sliding of the connecting plate 7, thereby achieving precise control of the movement of the connecting plate 7, ensuring that the half-chuck 6 can adjust the spacing according to the preset path to stably clamp shafts of different diameters, ensuring accurate and reliable testing.

[0037] Specifically, the sliding assembly 18 includes a slide rail 19 and a slider 20. The slide rail 19 is fixed to the side of the base 8 where the connecting plate 7 is mounted. The axial direction of the slide rail 19 is parallel to or coincides with the Z axis, and the slider 20 is arranged between the slide rail 19 and the connecting plate 7. By fixing the slide rail 19 to the side of the base 8 with its axial direction parallel to or coincides with the Z axis, and placing the slider 20 between the slide rail 19 and the connecting plate 7, precise guidance of the connecting plate 7 in the Z axis direction is achieved, thereby improving the adaptability and accuracy of the inspection fixture to the axis in the Z axis.

[0038] Furthermore, limit rods 21 are installed at both ends of the sliding travel of the connecting plate 7. The limit rods 21 at both ends are fixed to the base 8 and are used to limit the travel of the connecting plate 7. By providing the limit rods 21 to limit the travel of the connecting plate 7, it is possible to prevent the connecting plate 7 from colliding with other components or being damaged due to exceeding the normal range during the sliding process, ensuring that the connecting plate 7 slides smoothly within the preset safety travel, and ensuring the stability and accuracy of the movement of the half-chuck 6, thereby effectively maintaining the correct clamping state of the shaft and the normal progress of the detection work.

[0039] Specifically, the base 8 is arranged on the workbench 1 for reciprocating motion along the Y-axis. The two oppositely arranged half-chucks 6, the connecting plate 7, the weight block 9 and the connecting rope 10 are all installed on the base 8. The base 8 can be driven to make adaptive adjustments according to the position of the shaft, so that the half-chuck 6 can better cooperate with the shaft, thereby improving the clamping accuracy and reliability.

[0040] Furthermore, a mounting plate 26 is mounted on the workbench 1. The mounting plate 26 is provided with a driving cylinder that drives the base 8 to reciprocate along the Y-axis. The mounting plate 26 is also provided with a sensor 27, a guide rail 28, and a sliding block 29. The base 8 can be mounted on the sliding block 29, and the sensor 27 is mounted at the extreme end of the base 8's travel. By mounting the driving cylinder, sensor 27, and the guide rail 28 and sliding block 29 for guidance on the workbench 1, precise control and effective monitoring of the base 8's movement are achieved. The driving cylinder provides power for the base 8's movement, enabling it to accurately move along the Y-axis according to testing requirements, ensuring that the position of the half-chuck 6 and the shaft are adapted. The sensor 27 provides timely feedback when the base 8 reaches its extreme end, preventing damage to the equipment caused by overtravel of the base 8 and ensuring the safety and stability of the entire system. The coordination of the guide rail 28 and sliding block 29 ensures the smoothness and directionality of the base 8's movement, improving the accuracy of the shaft clamping and testing operations.

[0041] Preferably, at least one guide post 17 is erected on the side of the base 8 where the weight block 9 is mounted, and the upper end of the guide post 17 is in a vacant state, so that the weight block 9 can be added to or removed from the top of the guide post 17. By erecting at least one guide post 17 with a vacant upper end on the side of the base 8 where the weight block 9 is mounted, the weight block 9 can be added to or removed from the top of the guide post 17, thereby realizing convenient adjustment of the quantity or quality of the weight blocks 9, and thus flexibly changing the tension acting on the connecting rope 10, thereby accurately adjusting the clamping force of the half-chuck 6 to adapt to shafts of different types, sizes and different testing requirements, ensuring that the shaft can be stably and appropriately clamped under various testing conditions, and improving the versatility and adaptability of the inspection fixture.

[0042] During installation, the ends of the connecting rope 10 are fixed and locked to the weight block 9 and the connecting plate 7 respectively. The two ends of the connecting rope 10 can be connected by fasteners, such as screws. In this embodiment, a clamping cylindrical block is used to match the weight block 9 and the connecting plate 7. During use, the force is adjusted by adding a new weight block 9 to the original weight block 9. In this way, the tension of the connecting rope 10 can be changed via the pulley 16, thereby accurately adjusting the clamping force of the half-chuck 6 to meet the detection requirements of different axes.

[0043] Preferably, the base 8 and the connecting rope 10 are connected by a pulley 16, and the pulley 16 is movably connected to the base 8. The connecting rope 10 is wrapped around the rolling groove of the pulley 16 to achieve flexible steering and smooth movement of the connecting rope 10 on the base 8, reducing the friction resistance between the connecting rope 10 and the base 8, and ensuring that the connecting plate 7 and the weight block 9 connected at both ends of the connecting rope 10 can move more smoothly and accurately under the traction of the connecting rope 10, so that the half-chuck 6 obtains a stable and continuous clamping force, ensuring the clamping effect on the shaft, and improving the stability and reliability of the detection process.

[0044] Specifically, a positioning block 30 is installed on the top surface of the base 8, and both ends of the positioning block 30 extend along the direction of the connecting plate 7 and the weight block 9 installed on the base 8 respectively. The pulley 16 can be installed at both ends of the positioning block 30. By installing the positioning blocks 30 with both ends extending on the top surface of the base 8 and placing the pulley 16 at both ends, the pulley 16 can be accurately positioned and stably supported, thereby ensuring the accuracy and reliability of the inspection of the inspection fixture.

[0045] Preferably, the base 3 and the workbench 1 can perform reciprocating motion in the X-axis direction through a cylinder, and the two half-clamps 4 can achieve reciprocating motion towards or away from each other in the Y-axis direction through a double-piston cylinder, so as to accurately adjust the position of the axis in the inspection fixture in the X and Y dimensions according to the size and position of different axes, ensure that the half-clamp 4 can accurately clamp the axis, and improve the compatibility of the inspection fixture with axes of various sizes and the accuracy of detection.

[0046] Preferably, a support seat 23 is provided on the base 3, and the working surface of the support seat 23 is set as a matching surface for matching with the surface of the shaft product. Preferably, the two half-clamps 4 are set as a group, and at least two groups are provided on the base 3. Preferably, the support seat 23 is set in the middle of the two groups of two half-clamps 4, and the support seat 23 is provided with at least two matching surfaces for matching with the surface of the shaft product, so as to achieve a more stable clamping and more precise positioning of the shaft product. The matching surface of the support seat 23 fits the surface of the shaft product, and the shaft product is supported and preliminarily positioned from the center position to prevent the shaft product from shaking or deflecting during the inspection process; multiple groups of half-clamps 4 clamp the shaft product from both sides, further strengthening the fixing effect of the shaft, so that the shaft product can maintain a stable state during inspection, thereby effectively improving the inspection accuracy.

[0047] Specifically, the support base 23 is positioned below the two half-clamps 4. Its width is smaller than that of the half-clamps 4, and both the mating surface and the clamping surface of the half-clamps 4 are V-shaped. This allows the mating surface and half-clamps 4 to effectively support the shaft product from the center of the bottom. Its shape allows the shaft product to be naturally centered during placement, reducing concentricity errors caused by positional deviations and improving the accuracy of the inspection fixture for shaft products of different sizes.

[0048] Preferably, the base 3 moves with the measuring head 12, so that the measuring head 12 and the shaft product are relatively stationary. When the measuring head 12 reciprocates along the Z axis, it is intuitively observed whether the measuring head 12 is matched with the hole position of the shaft product, that is, whether the hole position of the shaft product is qualified can be measured; the measuring rod 14 moves toward the two half-clamps 4 along the carrier 13, and the measuring rod 14 is resiliently set on the carrier 13 along the X-axis direction, which enables the measuring rod 14 to contact the shaft more flexibly and adapt to the measurement of the shaft at different positions. At the same time, the resilient design can prevent the measuring rod 14 from causing damage to the shaft; the measuring meter 15 is installed at one end away from the two half-clamps 4 and at the relatively moving end set at the half-clamp 6, and can measure the shaft from different angles, thereby improving the comprehensiveness and accuracy of the measurement.

[0049] Specifically, the measuring rod 14 includes a contact rod body 24 and a force measuring rod body 25 whose axes are on the same center line. The contact rod body 24 and the force measuring rod body 25 are installed on the carrier 13 in sequence so as to be resilient toward the two half-clamps 4. The measuring meter 15 is arranged at the end of the force measuring rod body 25 away from the contact rod body 24.

[0050] Furthermore, the front end of the contact rod 24 is a test head 31, and the rear end of the contact rod 24 is provided with two stop plates 32. The diameter of the stop plates 32 is larger than the diameter of the shaft of the contact rod 24. The shaft of the contact rod 24 between the two stop plates 32 is called the movable shaft 33. A fixed plate 34 is mounted on the carrier 13, through which the movable shaft 33 passes. The hole in the fixed plate 34 matches the shaft diameter of the movable shaft 33. The length of the movable shaft 33 is greater than that of the fixed plate 34, and the movable shaft 33 can slide along the fixed plate 34. The two stop plates 32 are respectively clamped on opposite sides of the fixed plate 34. The sliding travel of the movable shaft 33 is determined by the stop plates 32. A spring 35 is mounted on the movable shaft 33. Specifically, the structure of the force measuring rod body 25 is consistent with the structure and installation method of the contact rod body 24, and both have a spring 35, a limit plate 32 and a movable shaft body 33. The difference is that the front end of the force measuring rod body 25 does not have a test head 31, and directly contacts the limit plate 32 at the rear end. Its function is to support the approaching limit plate 32.

[0051] When the test head 31 moves along with the carrier 13 toward the half-clamp 4 that clamps the shaft product, the test head 31 contacts the shaft product, the movable shaft 33 moves along the fixed block, the limit plate 32 at the front end compresses the spring 35, and the limit plate 32 at the rear end presses onto the force measuring rod 25. The force measuring rod 25 continues to compress backward until it presses onto the measuring gauge 15, completing the measurement.

[0052] Through the coordination between the contact rod 24, the force-measuring rod 25, the test head 31, the limit plate 32, the movable shaft 33, the fixed plate 34, and the spring 35, when the test head 31 moves with the carrier 13 toward the half-jig 4 and contacts the shaft product, the sliding of the movable shaft 33 on the fixed plate 34, the compression of the spring 35 by the limit plate 32, and the pushing of the connecting plate 7, further drive the force-measuring rod 25 to compress until it touches the measuring meter 15, thereby achieving accurate measurement of the force applied to the shaft product during testing. This design ensures that during the contact and force transmission process, the various components work together to convert the external force applied to the shaft product into a measurable signal, improving the accuracy and reliability of the measurement and adapting to the testing of shaft products with different force levels.

[0053] Preferably, dustproof covers can be installed on the contact rod 24, the force measuring rod 25 and the measuring meter 15 to improve the cleanliness of the inspection tool and prevent dust from falling on the parts, ensuring that the assembly accuracy and quality of each part are not affected.

[0054] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention.
