[0036] A cylindrical shaft is a component typically made of hard materials such as metal. It is a crucial part connecting the power source and the load; wheels and other rotating parts rotate around the shaft to transmit power and motion. As an important mechanical part, the straightness of the cylindrical shaft has a vital impact on subsequent assembly and the overall performance of the equipment. However, during processing, transportation, or storage, cylindrical shafts may be subjected to various external forces, causing deformations such as bending and twisting, thus affecting their straightness. Traditional methods for straightening cylindrical shafts usually rely on manual operation, which is not only inefficient but also makes it difficult to guarantee the accuracy and comprehensiveness of the correction.

[0037] Furthermore, some existing mechanical straightening equipment is complex in structure, cumbersome to operate, and has poor collimation and straightening effects. To overcome these shortcomings, a structure capable of efficiently and accurately straightening the collimation of round shafts is needed.

[0038] The following is for reference only. Figure 1 To be continued Figure 4 This invention describes a collimation and correction structure and device for a round shaft component according to an embodiment of the present invention, which can achieve comprehensive and accurate collimation and correction of the round shaft component with high correction efficiency.

[0039] Reference Figures 1 to 3 A collimation and correction structure for a round shaft according to a first aspect embodiment of the present invention includes:

[0040] The upper adjustment assembly 100 includes a first lifting drive mechanism 110, a lifting bracket 120, a rotary drive mechanism 130, a rotary shaft 140, drive wheels 150, and a pressure block 160. The lifting bracket 120 is connected to the first lifting drive mechanism 110, which drives the lifting bracket 120 to achieve lifting. The rotary drive mechanism 130 and the pressure block 160 are both connected to the lifting bracket 120. The rotary shaft 140 is rotatably connected to the lifting bracket 120. Two drive wheels 150 are provided, both connected to the rotary shaft 140. The two drive wheels 150 are located opposite each other on the pressure block 160. On the side, the rotating shaft 140 is also connected to the rotating drive mechanism 130. The rotating drive mechanism 130 is used to drive two drive wheels 150 to rotate through the rotating shaft 140. The bottom of the pressure block 160 is provided with an arc positioning groove 161 with the central axis parallel to the rotating shaft 140. The bottom surfaces of the two drive wheels 150 are located on opposite sides of the arc positioning groove 161. After the pressure block 160 presses the round shaft through the arc positioning groove 161, the drive wheel 150 contacts the circumferential surface of the round shaft. The rotation of the drive wheel 150 can drive the round shaft to rotate, thereby cooperating with the lower adjustment component 200 to perform alignment correction on the round shaft.

[0041] The lower adjustment assembly 200 includes a second lifting drive mechanism 210, an elastic module 220, and a correction block 230. The two ends of the elastic module 220 are respectively connected to the second lifting drive mechanism 210 and the correction block 230, so that the correction block 230 forms a movement tendency away from the second lifting drive mechanism 210. That is, the correction block 230 is connected to the second lifting drive mechanism 210 through the elastic module 220. The correction block 230 is located directly below the pressure block 160. The second lifting drive mechanism 210 is used to drive the correction module to lift and lower. The correction module is used to cooperate with the pressure block 160 and the drive wheel 150 to perform alignment correction on the round shaft.

[0042] The mounting assembly 300 includes a first translation drive mechanism 310, a first translation seat 320, and a material support plate 330. The first translation seat 320 is connected to the first translation drive mechanism 310, and the driving direction of the first translation drive mechanism 310 is parallel to the rotation axis 140. The first translation seat 320 is provided with a clearance groove 321, and a second lifting drive mechanism 210 is located in the clearance groove 321. The clearance groove 321 is used to make way for the second lifting drive mechanism 210. There are two material support plates 330, both of which are connected to the first translation seat 320. When the first translation drive mechanism 310 drives the first translation seat 320 to translate in a direction parallel to the rotation axis 140, the two material support plates 330 follow suit and achieve translational movement. During the translation of the first translation seat 320, the second lifting drive mechanism 210 makes way for the material support plate 330. The shaft moves within the groove 321. Two support plates 330 are located on opposite sides of the relief groove 321. The two support plates 330 support the two ends of the round shaft, effectively improving the stability of the support effect. Each support plate 330 has a support groove 331 on its top for supporting the round shaft. The opposite ends of the round shaft are respectively located in the two support grooves 331. Each support groove 331 has a limiting member 340 on the side away from the correction block 230. The two limiting members 340 are distributed along the extension direction of the rotation axis 140. The opposite two groove walls of the support groove 331 are distributed in a direction perpendicular to the rotation axis 140. The two limiting members 340, together with the two support grooves 331, can position the round shaft in two dimensions in the horizontal direction, effectively improving the translation effect.

[0043] The working process is as follows: the round shaft is placed on two material support grooves 331, the first lifting drive mechanism 110 drives the lifting bracket 120 to descend, the arc positioning groove 161 is engaged with the round shaft, the second lifting drive mechanism 210 drives the correction block 230 to rise and abut against the bottom of the round shaft, the rotation drive mechanism 130 drives the rotation shaft 140 to rotate, the two drive wheels 150 rotate synchronously and drive the round shaft to rotate, the correction block 230 cooperates with the pressure block 160 to align and correct the round shaft; the first translation drive mechanism 310 drives the first translation seat 320 to translate, thereby driving the round shaft to move relative to the correction block 230 and the pressure block 160, which can correct and adjust the different positions of the round shaft, and can effectively improve the correction and adjustment effect.

[0044] The first lifting drive mechanism 110 drives the pressure block 160 and the drive wheel 150 to press the round shaft from the top, stably pressing the round shaft onto the material support groove 331 for reliable positioning. The rotation drive mechanism 130 drives the drive wheel 150 to rotate, and the second lifting drive mechanism 210 drives the correction block 230 to push from the bottom of the round shaft, reliably aligning and correcting the rotating round shaft with high efficiency. Furthermore, the correction block 230 is connected to the second lifting drive mechanism 210 via the elastic module 220, effectively preventing... To prevent unnecessary deformation of the round shaft due to excessive force, the alignment and correction action is accurate and reliable. By adjusting the relevant parameters of the upper adjustment component 100 and the lower adjustment component 200, it can adapt to round shafts of different sizes and shapes, effectively improving the versatility and flexibility of the equipment. The first translation drive mechanism 310, in conjunction with the material support plate 330, can drive the round shaft to translate along the extension direction of the rotation axis 140. The correction block 230, in conjunction with the pressure block 160, can achieve alignment and correction at different positions of the round shaft, providing comprehensive correction and adjustment effects and effectively improving the correction and adjustment results. By setting two material support plates 330, a material support groove 331, and a limiting component 340, it can be ensured that the round shaft is stably supported in the designated position during the correction process, avoiding correction errors caused by the shaking or slippage of the round shaft, further improving the correction accuracy and stability. Through modular design, it is possible to achieve simple connection between various components, making it easy to disassemble and assemble, which can greatly simplify the maintenance and upkeep of the equipment.

[0045] It is understood that the top two sides of the correction block 230 are provided with a first rounded chamfer 231, and the material support groove 331 is provided with a second rounded chamfer 332 near the edge of the correction block 230. The two first rounded chamfers 231 and the two second rounded chamfers 332 are arranged opposite to each other, and the first rounded chamfers 231 and the second rounded chamfers 332 are both arranged facing the extension direction of the round shaft.

[0046] By setting the first chamfer 231 and the second chamfer 332, the reliability of the adjustment action can be effectively improved, and damage to the round shaft component can be avoided by the edges and corners. During the calibration, the round shaft component rotates under the drive of the drive wheel 150. The second chamfer 332 can prevent the edge of the material support plate 330 from scratching the round shaft component, and the second chamfer 332 can prevent the calibration block 230 from scratching the round shaft component. When the first translation drive mechanism 310 drives the two material support plates 330 to translate, the round shaft component translates relative to the calibration block 230. The first chamfer 231 can prevent the edges and corners of the calibration block 230 from scratching the round shaft component. The overall alignment and calibration operation of the round shaft component is stable and reliable.

[0047] Understandably, the pressure block 160 is made of copper. Copper has good corrosion resistance, as well as good ductility and toughness. It can maintain a stable shape and size during the calibration process, thereby ensuring the accuracy of the calibration.

[0048] It is understood that the elastic module 220 includes a sleeve 221, a limiting piece 222, a spring 223, and a vertical shaft 224. The sleeve 221 is connected to the second lifting drive mechanism 210. The limiting piece 222 is slidably connected in the sleeve 221. The top opening of the sleeve 221 is smaller than the area of ​​the limiting piece 222 to ensure that the limiting piece 222 is confined inside the sleeve 221. The opposite ends of the spring 223 are respectively connected to the limiting piece 222 and the sleeve 221 to make the limiting piece 222 form an upward movement tendency inside the sleeve 221. The opposite ends of the vertical shaft 224 are respectively connected to the correction block 230 and the limiting piece 222. The vertical shaft 224 extends outside the sleeve 221.

[0049] During operation, the second lifting drive mechanism 210 drives the sleeve 221 to rise, causing the alignment block 230 to abut against the bottom surface of the round shaft. This, in conjunction with the pressure block 160, achieves alignment correction of the round shaft. During the correction process, the spring 223 can dynamically adjust the correction pressure exerted by the alignment block 230 on the round shaft, effectively improving the reliability of the alignment correction action and preventing damage to the round shaft due to excessive correction force. Furthermore, by gradually driving the sleeve 221 to rise, the second lifting drive mechanism 210 can gradually adjust the correction effect. Based on the maximum compressible distance of the spring 223, the correction effect can be further ensured.

[0050] Understandably, the lower adjustment assembly 200 also includes an infrared sensor 240. The infrared sensor 240 is located on one side of the material support plate 330, and the probe of the infrared sensor 240 faces the position between the material support grooves 331. The infrared sensor 240 is used to detect the curvature of the round shaft between the two material support grooves 331. Based on the detection result of the curvature, the collimation correction time can be accurately controlled, thereby effectively improving the efficiency of collimation correction.

[0051] It is understandable that the circumferential surface of the drive wheel 150 is provided with an anti-slip buffer layer 151, which can effectively improve the driving positioning effect of the drive wheel 150 on the round shaft.

[0052] Specifically, the anti-slip buffer layer 151 is configured as a double-ring structure, that is, each drive wheel 150 has an anti-slip buffer layer 151 consisting of two sets of spaced-apart annular anti-slip rings on its circumferential surface, which can improve the stability of the rotation drive action.

[0053] It is understood that the rotary drive mechanism 130 includes a motor 131, a drive gear 132, a transmission gear 133, and a driven gear 134. The motor 131 is connected to the lifting bracket 120, the drive gear 132 is connected to the motor 131, and the driven gear 134 is connected to the rotating shaft 140. The two sides of the transmission gear 133 are respectively meshed with the drive gear 132 and the driven gear 134. The drive gear 132, transmission gear 133, and driven gear 134 can drive the rotating shaft 140 to rotate, thereby driving the two drive wheels 150 to rotate, thus realizing the rotary drive of the round shaft. Specifically, the first lifting drive mechanism 110 and the first translation drive mechanism 310 are both cylinders used to output linear driving force.

[0054] Reference Figure 4 A second aspect embodiment of the present invention provides a collimation and correction device for a circular shaft, comprising the collimation and correction structure for the circular shaft according to any of the first aspects embodiments described above.

[0055] Understandably, the alignment and correction device for the round shaft also includes a feeding assembly 400, a conveying assembly 500, and a discharging assembly 600. The conveying assembly 500 is located below the upper adjusting assembly 100. The feeding assembly 400 and the discharging assembly 600 are located on opposite sides of the conveying assembly 500. The feeding assembly 400 is used to supply the round shaft, and the discharging assembly 600 is used to collect or output the completed round shaft. The conveying assembly 500 is used to convey the round shaft in the feeding assembly 400 to the two material support grooves 331. The conveying assembly 500 is also used to convey the round shaft on the two material support grooves 331 to the discharging assembly 600. By feeding through the feeding assembly 400 and discharging through the discharging assembly 600, and in conjunction with the conveying assembly 500, continuous and reliable operation of the round shaft can be achieved, which can effectively improve the efficiency of alignment and correction.

[0056] It should be noted that the feeding assembly 400 can be a conveyor belt, or it can be configured to include a feeding box, a top block, and a lifting drive mechanism. The feeding box has several steps, and the top block is connected to the lifting drive mechanism. The lifting drive mechanism is used to drive the round shaft parts one by one up the steps via the top block, and finally deliver them to the handling assembly 500. The unloading assembly 600 can be configured to include a collection box, a waste box, a sorting plate, and a sorting lifting mechanism. The sorting plate has sorting grooves for supporting the round shaft parts, and the sorting plate is connected to the sorting lifting mechanism. The sorting lifting mechanism is used to drive the sorting plate to rise and fall, thereby cooperating with the handling assembly 500 to sort and store the round shaft parts into the collection box and the waste box. This configuration has a high degree of automation and can effectively reduce labor costs.

[0057] It is understood that the handling assembly 500 includes a second translation drive mechanism 510, a third lifting drive mechanism 520, and a handling rod 530. The handling rod 530 is provided with at least two sets of handling grooves 531 for supporting the round shaft. The two sets of handling grooves 531 can simultaneously transfer two round shafts, which can effectively improve handling efficiency. The third lifting drive mechanism 520 is connected to the second translation drive mechanism 510. The second translation drive mechanism 510 is used to drive the third lifting drive mechanism 520 to move in a horizontal direction perpendicular to the rotation axis 140. The handling rod 530 is connected to the third lifting drive mechanism 520. The third lifting drive mechanism 520 is used to drive the handling rod 530 to lift and lower, thereby cooperating to realize the transfer of the round shaft. Preferably, the handling rod 530 is located between two material support plates 330, which can effectively improve space utilization.
