Description

Technical Field

[0001] The present application relates to the technical field of probe arms, and in particular to a multi-axis probe arm. Background Art

[0002] With the rapid development of modern manufacturing, especially in high-precision manufacturing fields such as electronics, automobiles, aerospace, etc., more and more stringent requirements are placed on the measurement accuracy and efficiency of products. As a key measuring equipment, probe arms play an important role in the quality measurement, performance testing and fault diagnosis of various components.

[0003] Traditional probe arms have many limitations in their design. Among them, most traditional probe arms are only equipped with a four-axis fine-tuning mechanism, which means that they lack effective adjustment capabilities in the horizontal direction. In the actual measurement process, when faced with measurement points distributed in different horizontal positions, it is often necessary to prepare multiple probe arms with different angles to complete the measurement task because the probe cannot be accurately adjusted in the horizontal direction. This not only increases the equipment procurement cost and storage space, but also makes the measurement process cumbersome and complicated, seriously affecting the measurement efficiency and production progress.

[0004] Although some probe arms have tried to introduce the fifth-axis adjustment function, they have failed to achieve effective fine-tuning positioning. These fifth-axis adjustment mechanisms can only perform rough angle adjustments in actual applications, and cannot meet the needs of precise control of the probe posture in high-precision measurement scenarios. As a result, the adjustment function of this axis has no practical effect in actual operations, and cannot provide strong guarantees for the accuracy and reliability of measurements. It is difficult to adapt to the urgent needs of modern manufacturing for all-round and high-precision measurement of complex components. Summary of the invention

The adjusting rod 32 is threaded through the connecting block 9. The adjusting knob 10 is fixedly mounted on the adjusting rod 32. The three connecting blocks 9 are respectively fixedly mounted on the first fixed plate 26, the second fixed plate 28 and the third fixed plate 8.

The limit plate 71 is provided with a limit slot 72, and the limit block 73 is movably arranged in the limit slot 72.

[0042] In the specific setting, the limit plate 71 and the limit block 73 are respectively installed on the fixed plate and the movable plate of the first axis adjustment mechanism, the second axis adjustment mechanism and the third axis adjustment mechanism, and are used to limit the corresponding fixed plate and the movable plate to improve the adjustment accuracy of the fixed plate and the movable plate.

[0043] The fifth axis adjustment mechanism includes a fixed block 5, which is fixedly installed on the L-shaped connecting piece 1. A second fine-tuning knob 20 and a knurled high nut 18 are respectively provided at both ends of the fixed block 5. A supporting ring 24 is provided on the knurled high nut 18. An adapter block 3 is provided between the second fine-tuning knob 20 and the supporting ring 24. The adapter block 3 is rotatably installed on the second rotating shaft 23 through a thrust ball bearing 22. A deep groove ball bearing 21 is sleeved on the bottom of the second rotating shaft 23.

[0045] Through the above technical solution, the five-axis probe arm can be adjusted to meet the usage requirements of different scenarios.

[0046] Specifically, the multi-axis probe arm realizes precise position control of the probe through the coordinated operation of multiple axis adjustment mechanisms. In the horizontal direction, the first movable plate 27 of the first axis adjustment mechanism can slide relative to the first fixed plate 26. By turning the adjustment knob 10, the adjustment rod 32 is driven to push the first movable plate 27 to move, so as to realize the position adjustment of the probe in a horizontal direction. The second axis adjustment mechanism is perpendicular to the first axis adjustment mechanism, and its second movable plate 29 slides on the second fixed plate 28. Through the same adjustment method, the displacement of the probe in another horizontal direction is realized. The cooperation of the two can accurately determine the position of the probe in the horizontal plane of the lower surface of the connecting plate 31, so as to meet the access requirements of measurement points at different horizontal positions.

[0047] In the vertical direction, the third movable plate 25 of the third axis adjustment mechanism can slide along the third fixed plate 8. The operation of the adjustment knob 10 and the adjustment rod 32 causes the third movable plate 25 to move up and down, thereby changing the height of the probe to adapt to measurement objects of different heights.

[0048] The fifth-axis adjustment mechanism on the L-shaped connector 1 can perform coarse and fine adjustments to the angles of the mounting block 2 and the probe connector 12. The fourth-axis adjustment mechanism at one end of the mounting block 2 can further accurately adjust the angle of the probe connector 12, so that the probe can contact the measuring point in the best posture to ensure the accuracy and reliability of the measurement. Through the precise coordination of the axis adjustment mechanisms, precise control of the probe position and posture can be achieved to complete various complex measurement tasks.

[0049] The beneficial effects of adjusting each axis are:

[0050] First-axis and second-axis adjustment: Dual-axis adjustment in the horizontal direction can cover a larger area on the lower surface of the connecting plate 31. For tasks that require measurement at multiple positions in a plane, the adjustment of these two axes can quickly and accurately move the probe to the target position, thereby improving measurement efficiency and flexibility.

[0051] Third-axis adjustment: The vertical adjustment allows the probe to adapt to measuring objects of different heights. For the measurement of object surfaces with height differences or parts with different hierarchical structures, the third-axis adjustment mechanism can accurately control the vertical position of the probe to ensure good contact between the probe and the measuring point, avoiding problems such as inaccurate measurement or probe damage due to height differences, greatly expanding the application scenarios of the multi-axis probe arm.

[0052] Fourth axis adjustment: The angle adjustment of the probe connector 12 can ensure that the probe is perpendicular to the measuring surface or contacts at a predetermined angle, thereby improving the accuracy and reliability of the measurement.

[0055] X-axis: 12mm fine adjustment,

[0056] Y axis: 12mm fine adjustment,

[0057] Z axis: 12mm fine adjustment, coarse adjustment greater than 40mm, adjust the forearm installation position,

[0058] Fine-tuning accuracy: 5μm,

[0059] Fourth axis: Angle adjustment: pitch greater than 10°,

[0061] Embodiment 2

[0062] In order to solve the problem that during the installation of the L-shaped connector 1 to the third movable plate 25, it is necessary to manually support all the components connected to the L-shaped connector 1, which makes it difficult to accurately align the adjustment hole 101 with the installation hole 251, causing installation deviation and installation difficulty, a supporting mechanism is provided on the third movable plate 25 to support the L-shaped connector 1, thereby reducing the difficulty and workload of manual installation and adjustment of the position of the L-shaped connector 1.

[0063] The third movable plate 25 and the L-shaped connecting member 1 are respectively provided with a plurality of mounting holes 251 and adjustment holes 101. The L-shaped connecting member 1 is mounted on the third movable plate 25 by means of a fastening screw 6. A movable groove 252 is provided on one side of the third movable plate 25. A supporting mechanism is provided in the movable groove 252. The supporting mechanism includes a mounting rod 332. The mounting rod 332 is fixedly mounted in the movable groove 252. An adjusting screw 333 is rotatably connected in the mounting rod 332. A lifting block 334 is threadedly connected to the adjusting screw 333. The lifting block 334 is slidably connected to the inner wall of the mounting rod 332. The lifting block 334 is slidably connected to the inner wall of the mounting rod 332. A supporting plate 33 is fixedly connected to one side of 34, an insert block 331 is fixedly connected to the upper surface of the supporting plate 33, a slot is opened on the lower surface of the L-shaped connecting piece 1, the insert block 331 is inserted into the slot, a driving mechanism 34 is arranged on the upper end of the supporting mechanism, the driving mechanism 34 comprises a handle 341 and a rotating rod 342, the rotating rod 342 is rotatably installed in the L-shaped connecting piece 1, the handle 341 is fixedly installed on one end of the rotating rod 342, a worm 343 is fixedly installed on the rotating rod 342, a worm gear 344 is meshingly connected to one side of the worm 343, and the worm gear 344 is fixedly sleeved on the upper end of the adjusting screw 333.

[0064] The L-shaped connector 1 is connected to the third movable plate 25 by fastening screws 6, and the relative positions thereof can be adjusted by using a plurality of mounting holes 251 on the third movable plate 25 and adjustment holes 101 on the L-shaped connector 1 to meet different installation and positioning requirements.

[0065] A supporting mechanism is provided in the movable groove 252 on one side of the third movable plate 25, and its working principle is as follows: when it is necessary to adjust the height of the L-shaped connector 1, the operator rotates the handle 341 to drive the rotating rod 342 to rotate, and the worm 343 on the rotating rod 342 rotates accordingly, driving the worm wheel 344 and the adjusting screw 333 to rotate synchronously, so that the rotation of the adjusting screw 333 is converted into the up and down linear motion of the lifting block 334, and then drives the supporting plate 33 and the plug block 331 thereon to move up and down. The plug block 331 is inserted into the slot on the lower surface of the L-shaped connector 1, which plays a role of limiting the L-shaped connector 1 and improves the stability of the lifting and lowering of the L-shaped connector 1. Through the above technical solution, it can play a supporting role when the L-shaped connector 1 is installed on the third movable plate 25, so that the staff can more easily adjust and fix the position of the L-shaped connector 1, and realize the rapid installation of the quick L-shaped connector 1.

[0066] The beneficial effects of the above technical solution are:

[0067] Flexible installation and positioning: Through the cooperation of the mounting hole 251 on the third movable plate 25 and the adjustment hole 101 on the L-shaped connector 1, as well as the fastening screws 6, the L-shaped connector 1 has a certain flexibility in position adjustment when connected to the third movable plate 25. The initial installation position of the L-shaped connector 1 can be conveniently adjusted according to specific measurement tasks and equipment layout to adapt to different working scenarios and measurement requirements, thereby improving the versatility and adaptability of the entire multi-axis probe arm.

[0068] Installation is more labor-saving and convenient: the design of the supporting mechanism and its driving mechanism 34 realizes precise height adjustment of the L-shaped connector 1. Compared with the traditional method of directly taking the L-shaped connector 1 and fitting it with the third movable plate 25 for installation, it can reduce the workload of the staff and improve the stability of the L-shaped connector 1 and the accuracy of the alignment of the adjustment hole 101 and the installation hole 251.

[0069] Convenience of operation: The driving mechanism 34 composed of a handle 341, a worm 343 and a worm wheel 344 is adopted. The operator only needs to turn the handle 341 to adjust the height of the support plate 33. The operation is simple and intuitive, and does not require complicated tools or professional skills. The worm wheel 344 and worm 343 transmission have a certain self-locking characteristic. After adjusting to the required height, the position of the support plate 33 can be kept stable to prevent height changes caused by vibration or other external factors, and it can be more convenient for the staff to fix the L-shaped connector 1 by tightening the screws 6.

[0070] In summary, the working principle of a multi-axis probe arm in an embodiment of the present invention is:

[0071] The precise position control of the probe is achieved through the coordinated operation of multiple axis adjustment mechanisms. In the horizontal direction, by rotating the adjustment knob 10 of the first axis adjustment mechanism, the adjustment rod 32 drives the first movable plate 27 to move, so as to adjust the position of the probe in a horizontal direction. The second axis adjustment mechanism is perpendicular to the first axis adjustment mechanism, and the same adjustment method is used to achieve the displacement of the probe in another horizontal direction. The cooperation of the two can accurately determine the position of the probe in the horizontal plane of the lower surface of the connecting plate 31, so as to meet the access requirements of measurement points at different horizontal positions.

[0072] In the vertical direction, the operation of the adjusting knob 10 and the adjusting rod 32 causes the third movable plate 25 to move up and down, thereby changing the height of the probe to adapt to measurement objects of different heights.

[0073] The relative positions of the mounting holes 251 on the third movable plate 25 and the adjustment holes 101 on the L-shaped connector 1 are adjusted to meet different installation and positioning requirements. Specifically, the rotating handle 341 drives the rotating rod 342 to rotate, and the worm 343 on the rotating rod 342 rotates accordingly, driving the worm gear 344 and the adjusting screw 333 to rotate synchronously, so that the rotation of the adjusting screw 333 is converted into the up and down linear motion of the lifting block 334, thereby driving the supporting plate 33 and the plug block 331 thereon to move up and down, thereby driving the L-shaped connector 1 to rise and fall, and can play a supporting role when the L-shaped connector 1 is installed on the third movable plate 25, so that the staff can more easily adjust and fix the position of the L-shaped connector 1, and realize the rapid installation of the quick L-shaped connector 1.

[0074] By adjusting the second fine-tuning knob 20 of the fifth-axis adjustment mechanism to rotate the adapter block 3 and the mounting block 2, the angle of the probe connector 12 can be roughly adjusted. The fourth-axis adjustment mechanism at one end of the mounting block 2 further accurately adjusts the angle of the probe connector 12 so that the probe can contact the measuring point in the best posture to ensure the accuracy and reliability of the measurement. Through the precise coordination of the adjustment mechanisms of each axis, precise control of the probe position and posture is achieved to complete various complex measurement tasks.

[0075] The electronic components and models used in the present invention can be determined according to actual needs.
