Description

Technical Field

[0001] This invention relates to the field of shaft inspection technology, and in particular to a composite rotary shaft ultra-precision outer diameter measuring instrument. Background Technology

[0002] Rotary shafts have wide and important applications in many fields. Not only are they crucial for the design and analysis of mechanical structures in engineering, but in aerospace, the design and control of aircraft rely heavily on the accurate manipulation of rotary shafts. For satellites in space, attitude control is essential for their normal operation and mission completion. Due to their unique properties and wide range of applications, rotary shafts occupy an important position in engineering, physics, materials science, and many other fields.

[0003] Missing measurements of the rotation axis can lead to a series of problems and challenges. Accurate measurement of the rotation axis is crucial for equipment stability, performance optimization, control precision, and safety. In complex mechanical systems such as aerospace vehicles, centrifuges, and crankshafts, if the rotation axis is not accurately measured or determined, the actual attitude information of the object cannot be accurately obtained. This can result in problems such as heading deviation and control correction lag. The rotating components of the system may experience significant vibration and imbalance, leading to increased equipment wear and vibration. In many industrial applications (such as large blowers and generators), missing or inaccurate measurements can cause imbalance of rotating components and overload of equipment structures.

[0004] In modern manufacturing, the precision requirements for products are increasingly stringent. Especially in fields such as aerospace, precision instruments, and electronics, even minute errors can lead to serious consequences. Composite rotary shaft ultra-precision measuring instruments offer extremely high measurement accuracy, accurately detecting various parameters of the rotary shaft and providing reliable data support for high-precision manufacturing. For example, in the manufacturing of aero-engines, the precision of the rotary shaft directly affects the engine's performance and reliability. Through technological breakthroughs and improvements in the accuracy of the measuring instrument, high-quality engine production can be ensured.

Detailed Implementation

[0030] refer to Figures 1 to 12The composite ultra-precision outer diameter measuring instrument for rotary shafts includes a rotating assembly 1 for clamping a shaft 104. The rotating assembly 1 detects the outer diameter of the shaft 104 and the rotary shaft, simultaneously restoring the true working state of the shaft 104. The rotating assembly 1 improves the stability of the shaft 104 when it deflects. A set of detection components 2 is provided on both sides of the rotating assembly 1. The detection components 2 are equipped with multi-angle adjustable reading heads 213. The circular grating 110 in the rotating assembly 1 needs to cooperate with the reading heads 213 to take readings during operation. The circular grating 110 is deflected by the rotating assembly 1. During operation, the detection component 2 adjusts the position of the reading head 213 to enable the detection of the shaft 104 even under deflection conditions, thereby improving the detection accuracy and efficiency of the shaft 104. The rotating component 1 is provided with a feeding component 3 on its side, on which multiple sets of shafts 104 are placed. The feeding component 3 automatically places the shafts 104 on the rotating component 1 and performs wiping and vertical detection on the shafts 104 to avoid the presence of shafts 104 with processing problems among the shafts 104 to be inspected. This invention automatically detects parameters such as the outer diameter and rotation axis of the shaft 104, thereby improving the detection efficiency and accuracy of the shaft 104.

[0031] The rotating assembly 1 includes a base 101, on which a placement plate 102 is mounted. A deflector 103 is rotatably mounted within the placement plate 102. Two sets of positioning plates 106 are slidably mounted on the deflector 103, mirror-imagely mounted on the deflector 103. A detection frame 115 is slidably mounted on the positioning plate 106, and multiple sets of detection wheels 116 are rotatably mounted on the detection frame 115. Each detection wheel 116 is equipped with a rotation meter. The detection wheels 116 are in contact with the shaft 104. When the shaft 104 rotates, it drives the detection wheels 116 to rotate. The outer diameter of the shaft 104 is measured by reading the rotation meter values ​​of the detection wheels 116. A positioning post 105 is slidably mounted on the positioning plate 106. A spring 107 is installed between the positioning plate 105 and the positioning plate 106. Two sets of positioning pins 105 press down on both ends of the shaft 104 to stabilize it. A support frame 108 is rotatably mounted on the positioning plate 106. Two sets of clamping rings 109 are slidably mounted inside the support frame 108. The clamping rings 109 clamp the rotating shaft of the shaft 104. When it is necessary to clamp the shaft 104, the rotating shaft of the shaft 104 is aligned with the two sets of clamping rings 109, driving the two sets of positioning plates 106 to slide on the deflection seat 103. The positioning plates 106 drive the support frame 108, clamping rings 109, and positioning pins 105 to move closer to the shaft 104, and the positioning pins 105 are in contact with the shaft 104. The drive clamping rings 109 move closer together, clamping the shaft 104 and fixing it in place. When the drive support frame 108 rotates on the positioning plate 106, it drives the shaft 104 to rotate. A circular grating 110 is installed on the positioning plate 106 to detect the shaft 104. A fastening electric cylinder 113 is installed in the middle of the deflection seat 103. An adjusting plate 114 is installed at the movable end of the fastening electric cylinder 113. A set of stabilizing plates 111 are rotatably installed on both sides of the adjusting plate 114. Multiple sets of clamping rings 112 are slidably installed on the stabilizing plate 111. The stabilizing plate 111 has slots, and multiple sets of rotating wheels are rotatably installed on the clamping rings 112. 117. The first rotating wheel 117 is in contact with the shaft 104. When it is necessary to restore the working state of the shaft 104, the fastening electric cylinder 113 is driven to work. The fastening electric cylinder 113 drives the adjusting plate 114 to move. The adjusting plate 114 gradually approaches the shaft 104, driving the stabilizing plate 111 to rotate on the adjusting plate 114. The stabilizing plate 111 drives the clamping ring 112 to align with the shaft 104, driving multiple sets of clamping rings 112 to move closer to each other. The clamping rings 112 drive the first rotating wheel 117 to be in contact with the shaft 104, increasing the stability of the shaft 104. Then, the deflection seat 103 is driven to rotate on the placement plate 102 to achieve the deflection of the shaft 104. The slot on the stabilizing plate 111 facilitates the reading of the adjusting frame 208.

[0032] The detection component 2 includes two sets of bases 201, which are respectively disposed on both sides of base 101. An adjustment plate 202 is slidably mounted on base 201, and an adjustment plate 203 is slidably mounted on adjustment plate 202. A wiping frame 205 and a detection plate 204 are slidably mounted on adjustment plate 203. An adjustment block 206 is slidably mounted on wiping frame 205, and a wiping plate 207 is rotatably mounted on adjustment block 206. The wiping plate 207 wipes the reading head 213, and the detection plate 204 slides... An adjusting frame 208 is provided, with a limit groove 209 on it. An adjusting shaft 210 is rotatably mounted on a detection plate 204, and an adjusting shaft 211 is rotatably mounted on the adjusting shaft 210. A limit ball 212 is provided at one end of the adjusting shaft 211, and a reading head 213 is provided at the other end. The limit ball 212 slides within the limit groove 209. When the adjusting frame 208 slides on the wiping frame 205, the adjusting frame 208 drives the limit groove 209 to move, and the limit groove 209 drives... When the limit ball 212 rotates, it drives the second adjustment shaft 211 to rotate on the first adjustment shaft 210. As the first adjustment shaft 210 rotates on the first detection plate 204, the first adjustment shaft 210 drives the second adjustment shaft 211 to rotate along its axis. The second adjustment shaft 211 then drives the reading head 213 to rotate with the limit ball 212, thus adjusting the position of the reading head 213. This causes the wiping frame 205 to slide on the third adjustment plate 203, and the first adjustment block 206 to slide on the wiping frame 205, thereby driving the wiping plate 204 to rotate. 7. After the wiping plate 207 is aligned with the adjusting shaft 210, the wiping plate 207 wipes the adjusting shaft 210 to ensure the cleanliness of the reading head 213 and improve the reading accuracy of the reading head 213. The adjusting plate 202 drives the adjusting plate 202 to slide on the base 201. The adjusting plate 202 drives the adjusting plate 3 203 and the detection plate 1 204 to move, changing the measurement position of the reading head 213 on the shaft 104. The detection plate 1 204 drives the adjusting plate 3 203 to slide on the adjusting plate 3 203, changing the distance between the reading head 213 and the shaft 104.

[0033] The feeding assembly 3 includes a base 301, on which a placement rack 306 is slidably mounted. Multiple sets of fixing blocks 310 are slidably mounted on the placement rack 306. An adjusting disc 313 is rotatably mounted on each fixing block 310. Two sets of clamping rings 314 are slidably mounted on the adjusting disc 313. When the clamping rings 314 approach each other, they clamp the shaft 104, driving the adjusting disc 313 to rotate on the fixing blocks 310. The adjusting disc 313 drives the clamping rings 314 and the shaft 104 to rotate. A support frame 302 is provided on the side of the base 301, and two sets of detection plates 30 are slidably mounted on the support frame 302. 3. Multiple sets of detection heads 311 are installed on the second detection plate 303. Each detection head 311 is equipped with a pressure sensor. The detection heads 311 are in contact with the shaft 104. When the two sets of second detection plates 303 approach each other, the second detection plate 303 drives the detection heads 311 to contact the shaft 104. As the two sets of second detection plates 303 gradually approach each other, the data from the pressure sensors on the detection heads 311 gradually changes, and the data from multiple sets of detection heads 311 are the same. If there are unevenness or other machining defects on the surface of the positioning post 105, the parameters of the detection heads 311 will change, thus detecting machining defects on the surface of the shaft 104. (The last sentence appears to be incomplete and possibly refers to a different topic.) A support frame 304 is slidably mounted on the side, and a cleaning column 305 is rotatably mounted on the support frame 304. The cleaning column 305 wipes the shaft 104, driving the support frame 304 to slide on the base 301. The support frame 304 drives the cleaning column 305 to approach the shaft 104 and wipe the shaft 104. The feeding assembly 3 also includes a base 4 307, on which an adjusting frame 2 308 is rotatably mounted. A feeding frame 309 is slidably mounted on the adjusting frame 2 308. A set of clamping rings 312 is slidably mounted on both sides of the feeding frame 309. The clamping rings 312 hold the shaft 104 that needs to be removed. The clamping mechanism is activated, and the loading rack 309 is driven to slide within the adjusting rack 2 308. The loading rack 309 drives the clamping ring 312 to align with the shaft 104. The two sets of clamping rings 312 are driven to move closer together, and the clamping rings 312 clamp the shaft 104. The fixing block 310 and the clamping ring 4 314 are driven to reset. The fixing block 310 is driven to move away from each other. The clamping ring 4 314 releases its fixation on the shaft 104. The loading rack 309 is driven to reset and the adjusting rack 2 308 is driven to rotate on the base 4 307. The adjusting rack 2 308 drives the shaft 104 toward the rotating assembly 1 and places the shaft 104 on the rotating assembly 1.

[0034] Working principle: During operation, the shaft 104 to be inspected is placed on the placement frame 306. Multiple sets of fixing blocks 310 are driven to move closer together. The fixing blocks 310 drive the adjusting plate 313 and the clamping ring 314 to align with the shaft 104. The clamping rings 314 then move closer together, clamping the shaft 104, thus completing the placement of multiple sets of shafts 104. When inspecting for machining defects in the shaft 104, the support frame 302 is driven to slide on the base 301. The support frame 302 drives multiple sets of inspection plates 303 to move, thus inspecting... After the second test plate 303 reaches both sides of the shaft 104, it drives the two sets of test plates 303 to approach each other. The test plates 303 drive the test head 311 to fit against the shaft 104. Based on the pressure sensor reading of the test head 311, it analyzes whether there are any processing defects in the shaft 104. When wiping the shaft 104, it drives the support frame 304 to slide on the base 301. The support frame 304 drives the cleaning column 305 to approach the shaft 104 and drives the cleaning column 305 to rotate. The cleaning column 305 wipes the shaft 104 to ensure the cleanliness of the shaft 104.

[0035] When the shaft 104 on the feeding assembly 3 needs to be placed on the rotating assembly 1, the second adjustment frame 308 is driven to rotate on the fourth base 307. The second adjustment frame 308 drives the feeding frame 309 and the clamping ring 312 to rotate, and drives the feeding frame 309 to slide on the second adjustment frame 308. The feeding frame 309 drives the clamping ring 312 to align with the shaft 104, and drives the two sets of clamping rings 312 to move closer to each other. The clamping rings 312 clamp the shaft 104. After the shaft 104 is clamped, the fixing block 310 and the fourth clamping ring 314 are driven to reset, and the fixing block 310 and the fourth clamping ring 314 are driven to move away from each other. The fourth clamping ring 314 releases the fixation of the shaft 104, drives the feeding frame 309 to reset, and drives the second adjustment frame 308 to rotate on the fourth base 307. The second adjustment frame 308 drives the shaft 104 to face the rotating assembly 1 and places the shaft 104 on the rotating assembly 1.

[0036] When the rotation axis of the shaft 104 is aligned with the two sets of clamping rings 109, the two sets of positioning plates 106 are driven to slide on the deflection seat 103. The positioning plates 106 drive the support frame 108, clamping rings 109, and positioning pins 105 to approach the shaft 104. The positioning pins 105 are in contact with the shaft 104, driving the clamping rings 109 to approach each other. The clamping rings 109 clamp the shaft 104, completing the fixation of the shaft 104. The moving detection frame 115 slides on the positioning plate 106. The detection frame 115 drives the detection wheel 116 to fit against the shaft 104, driving the support frame 108 to rotate on the positioning plate 106. The support frame 108 drives the clamping ring 109 to rotate, and the clamping ring 109 drives the shaft 104 to rotate. When the shaft 104 rotates, it drives the detection wheel 116 to rotate. The outer diameter of the shaft 104 is detected by reading the rotation meter value of the detection wheel 116.

[0037] Drive adjustment plate 202 slides on base 201, drive adjustment plate 3 203 slides on adjustment plate 202, and drive detection plate 1 204 slides on adjustment plate 3 203 to adjust the position of detection plate 1 204. Detection plate 1 204 drives reading head 213 to approach shaft 104. Reading head 213 cooperates with circular grating 110 to detect the deflection angle of shaft 104. When shaft 104 is deflected, fastening electric cylinder 113 is activated. The adjustment plate 114 is moved closer to the shaft 104, and the stabilizing plate 111 is driven to rotate on the adjustment plate 114. The stabilizing plate 111 drives multiple sets of clamping rings 112 to move, and the clamping rings 112 slide on the stabilizing plate 111. The clamping rings 112 drive the rotating wheel 117 to move so that the rotating wheel 117 fits against the shaft 104, thus completing the stable clamping of the shaft 104. The deflection seat 103 is driven to rotate on the placement plate 102 to achieve the deflection of the shaft 104.

[0038] After the deflection shaft 104 is deflected by a certain angle, the drive deflection seat 103 is stopped. At this time, the angle of the shaft 104 is adjusted, restoring the working state of the shaft 104 at different angles. The position of the reading head 213 is adjusted to ensure that the reading head 213 can cooperate with the circular grating 110 to detect the shaft 104. The driving adjustment plate 202, the adjustment plate 3 203 and the detection plate 204 are driven to complete the adjustment of the detection position of the reading head 213. When the driving adjustment frame 208 slides on the wiping frame 205, the adjustment frame 208 drives the limiting groove. When 209 moves, the limiting groove 209 drives the limiting ball 212 to rotate. The limiting ball 212 drives the second adjusting shaft 211 to rotate on the first adjusting shaft 210. When the first adjusting shaft 210 rotates on the first detection plate 204, the first adjusting shaft 210 drives the second adjusting shaft 211 to rotate along the axis of the first adjusting shaft 210. The second adjusting shaft 211 drives the reading head 213 to rotate with the limiting ball 212, thus completing the adjustment of the position of the reading head 213. The precise adjustment of the reading head 213 ensures that it cooperates with the circular grating 110, guaranteeing the accuracy of the reading.

[0039] After the shaft 104 is inspected, the first inspection plate 204 is driven to slide on the third adjustment plate 203. The first inspection plate 204 drives the third adjustment plate 203 to reset, drives the wiping frame 205 to slide on the third adjustment plate 203, drives the first adjustment block 206 to slide on the wiping frame 205, and drives the first adjustment block 206 to align the wiping plate 207 with the reading head 213. The wiping plate 207 is driven to rotate and come into contact with the reading head 213 to wipe the reading head 213, ensuring the cleanliness of the reading head 213 and improving the inspection accuracy of the shaft 104.
