Description

Technical Field

[0001] This invention relates to the field of measuring the long shaft dimensions of textile machines, specifically a non-contact visual measurement device for the processing dimensions of the long shaft of a textile machine. Background Technology

[0002] The long shaft of a textile machine usually refers to a rigid transmission shaft that runs through most or all of the length of the textile machine. Its main function is to serve as the core component for power distribution and synchronization control, transmitting the power of the main motor to various execution parts of the machine precisely and synchronously through a series of transmission elements. It is an indispensable core transmission component in traditional textile machinery.

[0003] Measuring the dimensions of the long shaft of a textile machine is a crucial step in manufacturing, installation, and maintenance, ensuring that the diameter of the journal is within the designed tolerances. Traditional contact measuring tools such as micrometers, calipers, or dial indicators can leave tiny scratches on the precision-machined shaft surface if operated improperly or if the probe contains hard particles. Non-contact optical measurement is often used. Laser scanning or optical imaging can instantly acquire massive point cloud data of the entire surface or a cross-section of the long shaft, accurately measuring its straightness and curvature. This avoids physical contact with the object being measured, fundamentally eliminating this risk. Existing measuring devices require the long shaft to be placed on a V-block or roller frame before the laser probe can scan it. If the long shaft is long, a portion of it must be scanned and measured first before the shaft is placed back on the V-block or roller frame to scan and measure the remaining portion. Due to the large size and weight of the long shaft, operation is inconvenient and can also cause wear on the shaft. Summary of the Invention

[0016] This invention, through the adjustment mechanism, utilizes the cooperation of opposite screws and two moving plates to adjust the position of the two mounting belts, thereby moving the electric roller seats on both sides of the long shaft further apart.

[0017] This invention, through a fixed support mechanism, enables the mounting tube to move along the outside of the support rod when the electric roller seat moves. The support rod provides guidance and support for the movement of the electric roller seat and enables the mounting tube to drive the support rod to move synchronously, thereby improving the stability of the long axis movement.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-8 The diagram shows a non-contact visual measurement device for the machining dimensions of a long shaft of a textile machine. It includes a base 1 and a gantry 2 fixedly mounted on the top of the base 1. A measuring host 3 is fixedly mounted on the top of the gantry 2, and a laser measuring probe 4 is located on the inner wall of the top of the gantry 2 at the bottom of the measuring host 3. Two symmetrically distributed mounting plates 5 are fixedly mounted on the top of the base 1. Multiple equidistantly distributed electric roller seats 6 are provided on opposite sides of each mounting plate 5. The long shaft is placed between the multiple electric roller seats 6, causing the electric roller seats 6 to drive the long shaft to rotate. The measuring host 3 scans and measures the long shaft through the laser measuring probe 4, collecting the dimensional data of the long shaft.

[0022] The pushing mechanism includes a mounting belt 7 disposed on the outside of the mounting support plate 5, and multiple electric roller seats 6 evenly distributed on the outside of the mounting belt 7. The mounting belt 7 enables the multiple electric roller seats 6 to rotate and move synchronously. The pushing mechanism also includes a mounting tube 10 fixedly installed on the bottom of the electric roller seats 6. The mounting tube 10 is fixedly installed on the outside of the mounting belt 7. A toothed belt 11 is fixedly installed on the inside of the mounting belt 7. Two symmetrically distributed inner support plates 12 are provided on the inside of the mounting belt 7. Multiple positioning rods 13 are fixedly installed between the two mounting support plates 5, and the inner support plates 12 are sleeved on the multiple positioning rods 13. On the outer side, a fixed plate 14 is fixedly installed between two adjacent inner support plates 12. Two symmetrically distributed drive rods 15 are rotatably installed between two mounting support plates 5. Both ends of the fixed plate 14 are provided with transmission wheels 16 that cooperate with the toothed belt 11, and the transmission wheels 16 are installed on the outer side of the adjacent transmission wheels 16, so that when the two drive rods 15 rotate, they can drive the toothed belt 11 to rotate and move through the transmission wheels 16. The toothed belt 11 drives the mounting belt 7 to rotate and move synchronously along the inner side of the inner support plate 12, so that the mounting belt 7 drives the electric roller seat 6 to move through the mounting tube 10. The electric roller seat 6 can then drive the long shaft to push onto the gantry. Below 2, the laser measuring probe 4 continuously measures the long axis. A first motor 17 is mounted on the top of the device base 1. The first motor 17 is fixedly installed on the outer side of the adjacent mounting plate 5, and its output end is fixedly connected to one end of the adjacent drive rod 15, enabling the first motor 17 to drive the corresponding drive rod 15 to rotate. The transmission wheel 16 on the outer side of the drive rod 15, in conjunction with the transmission wheel 16 on another drive rod 15, drives the toothed belt 11 to rotate. The pulley of the electric roller seat 6 has multiple centrally symmetrically distributed anti-slip grooves, allowing the electric roller seat 6 to drive the long axis to rotate through the anti-slip grooves, maintaining the surface... The smooth long shaft rotates continuously. Positioning rings 29 are fixedly installed on both sides of the transmission wheel 16, and a limiting ring 30 is fixedly installed on the outer side of the inner support plate 12. The outer side of the positioning ring 29 contacts the inner side of the positioning ring 29, so that the inner support plate 12 provides positioning for the positioning ring 29 through the limiting ring 30, thereby positioning the transmission wheel 16. Multiple triangular support plates 31 are fixedly installed on one side of the two mounting support plates 5 at equal intervals. The triangular support plates 31 are fixedly installed on the top of the device base 1, so that the triangular support plates 31 provide auxiliary support for the mounting support plates 5, ensuring that the positioning rod 13 provides stable support for the moving plate 8.

[0023] Example 2: Please refer to Figures 2-8This embodiment further illustrates Example 1. The adjusting mechanism shown in the figure includes a movable plate 8 disposed between two mounting support plates 5. The movable plate 8 adjusts the distance between the two mounting belts 7. The adjusting mechanism also includes a counter-rotating screw 18 rotatably mounted between the two mounting support plates 5. The two movable plates 8 are respectively fixedly mounted on the inner sides of the two fixed plates 14. The movable plates 8 are slidably mounted on the outer side of the positioning rod 13, and the two movable plates 8 are respectively threaded onto both ends of the counter-rotating screw 18. When the counter-rotating screw 18 rotates, the two movable plates 8 can move closer or further away from each other along the outer side of the positioning rod 13. A second motor 19 is provided on the top of the device base 1. The second motor 19 is fixedly mounted on the outer side of the adjacent mounting support plates 5, and the output end of the second motor 19 is fixedly connected to one end of the counter-rotating screw 18, enabling the second motor 19 to drive... The rotation of the counter-rotating screw 18 facilitates the adjustment of the distance between the two moving plates 8. A prismatic sleeve 20 is fixedly installed on the outer side of the drive rod 15, and a prismatic collar 21 is fixedly installed on the inner side of the transmission wheel 16. The prismatic collar 21 is slidably installed on the outer side of the prismatic sleeve 20, so that when the moving plate 8 moves, it can drive the two inner support plates 12 to move through the fixed plate 14, and the inner support plates 12 can drive the mounting belt 7 and the transmission wheel 16 to move. The mounting belt 7 can adjust the position of the electric roller seat 6 through the mounting tube 10, and can also drive the transmission wheel 16 to drive the prismatic collar 21 to move along the outer side of the prismatic sleeve 20, which facilitates the adjustment of the position of the transmission wheel 16. The laser measuring probe 4 is connected to the measuring host 3 through the electric telescopic rod 32, so that the electric telescopic rod 32 can adjust the height of the laser measuring probe 4, which is convenient for aligning with the long shaft with a larger outer diameter.

[0024] Example 3: Please refer to Figures 2-8This embodiment further illustrates other embodiments. The fixed support mechanism shown in the figure includes multiple support rods 9 equidistantly arranged between two mounting plates 5. The support rods 9 can provide guidance for the movement of the electric roller seat 6. The fixed support mechanism also includes a mounting plate 22 fixedly installed on the bottom of the electric roller seat 6. A mounting block 23 is fixedly installed on the side of the mounting plate 22 away from the electric roller seat 6, and a mounting tube 10 is fixedly installed on the outside of the mounting block 23. The mounting tube 10 is sleeved on the outside of the support rods 9, so that the support rods 9 provide support for the electric roller seat 6 through the mounting tube 10. Both ends of the mounting plate 9 are rotatably mounted with first pulleys 24. Guide rails 25 are fixedly mounted on corresponding sides of the two mounting plates 5. The first pulleys 24 are slidably mounted on the outer sides of adjacent guide rails 25, so that when the electric roller seat 6 rotates, it can drive the support rod 9 to move synchronously through the mounting tube 10. The support rod 9 drives the two first pulleys 24 to move synchronously along the outer sides of the two guide rails 25, keeping the support rod 9 supporting the electric roller seat 6. Two symmetrically distributed spring supports 26 are fixedly mounted on the side of the mounting plate 22 near the mounting block 23. A movable wheel 27 is rotatably mounted at the end away from the mounting plate 22. A first guide plate 28 is fixedly mounted on each corresponding side of the two movable plates 8, so that when the movable plates 8 move, they can drive the first guide plates 28 to move synchronously. The outer side of the first guide plate 28 contacts the outer side of the movable wheel 27. The elasticity of the spring support 26 causes the movable wheel 27 to abut against the outer side of the first guide plate 28, so that the two movable wheels 27 provide support for the electric roller seat 6 through the spring support 26 and the mounting plate 22, keeping the electric roller seat 6 in a horizontal state. A support rod 9 is rotatably mounted on the outer side. The second pulley 33 is fixedly installed with a second guide plate 34 between multiple positioning rods 13, and the outer side of the second pulley 33 is in contact with the outer side of the second guide plate 34, so that the second pulley 33 can move along the outer side of the second guide plate 34 to provide support for the middle position of the support rod 9. The guide rail 25 has an L-shaped cross-section, and the two ends of the first pulley 24 are in contact with the inner side of the guide rail 25 and the outer side of the mounting plate 5, respectively, so that the first pulley 24 can move between the inner side of the guide rail 25 and the outer side of the mounting plate 5 to prevent the support rod 9 from tilting.

[0025] Working principle: First, the operator places one end of the long shaft on the electric roller seat 6 located above the two mounting belts 7. The electric roller seat 6 drives the long shaft to rotate, making the long shaft rotate. At this time, the first motor 17 drives the corresponding drive rod 15 to rotate, which in turn drives the two corresponding transmission wheels 16 to rotate. The two transmission wheels 16 on the drive rod 15, together with the two transmission wheels 16 on the other drive rod 15, drive the two toothed belts 11 to rotate and move synchronously. The toothed belts 11 drive the mounting belt 7 to rotate and move synchronously along the inner side of the inner support plate 12, so that the mounting belt 7 drives the electric roller seat 6 to move through the mounting tube 10. Multiple electric roller seats 6 can push the long shaft to the bottom of the gantry 2, so that the laser measuring probe 4 can continuously measure the long shaft and transmit the measured data to the measuring host 3 to obtain the size data of the long shaft. With the continuous rotation and movement of multiple electric roller seats 6, it is convenient to measure the long shaft, thereby reducing the overall size of the device and reducing the measurement cost. When the outer diameter of the long shaft is large, the operator starts the second motor 19. The second motor 19 drives the counter-rotating screw 18 to rotate, causing the counter-rotating screw 18 to move the two moving plates 8 away from each other. The moving plates 8 drive the two inner support plates 12 to move synchronously through the fixed plate 14, causing the two inner support plates 12 to drive the mounting belt 7 to move closer to the adjacent mounting support plate 5, and drive the prismatic collar 21 on the transmission wheel 16 to move along the prismatic sleeve 20 on the outside of the drive rod 15. The electric roller seats 6 on the outside of the two mounting belts 7 can then move away from each other, making it easier to push long shafts with larger outer diameters. In addition, the mounting tube 10 on the electric roller seat 6 can move along the outside of the support rod 9. During the movement of the electric roller seat 6, it can also drive the first pulley 24 on the support rod 9 to move along the inside of the guide rail 25 through the mounting tube 10, maintaining the support rod 9's support for the electric roller seat 6, making it easier for the electric roller seat 6 to provide stable support for the long shaft, thereby facilitating the measurement of long shafts with larger outer diameters and improving the convenience of long shaft measurement.
