Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a turning device for machining annealing furnace rolls. Background Technology

[0002] As a core transmission component of industrial annealing furnaces, the surface accuracy and coaxiality of annealing furnace rollers directly affect the conveying stability and processing quality of annealed workpieces. Especially under high-temperature and heavy-load conditions, even slight bending deformation of the annealing furnace rollers can lead to defects such as workpiece misalignment and surface scratches. However, traditional turning equipment lacks a real-time online coaxiality detection mechanism, typically employing a manual inspection method after machining: that is, after turning, the roller's perpendicularity is checked offline using tools such as dial indicators and laser interferometers. If deformation exceeds the tolerance, re-clamping and rework are required. This method is not only inefficient but also fails to capture the dynamic deformation of the roller caused by cutting forces and thermal deformation during processing, resulting in high rework rates and extended processing cycles. Furthermore, the detection components are mostly fixed installations, unable to move along the entire roller axis for inspection, easily overlooking potential deformation hazards in critical central areas.

[0003] Annealing furnace rollers come in various diameters (commonly ranging from 50-300mm). Traditional turning equipment often uses fixed-size tailstock supports and central support structures. When changing rollers of different diameters, the entire support components must be disassembled and replaced, which is cumbersome and time-consuming. In addition, the tailstock support often uses a single clamping structure, which only clamps the roller shaft end through the center, lacking lateral restraint. During high-speed rotation, the shaft is prone to movement and offset, leading to machining eccentricity.

[0004] In summary, precision machining of annealing furnace rollers is one of the core applications of high-end industrial machine tools. The accuracy of coaxiality measurement during the machining process directly determines the finished product qualification rate. However, traditional machine tools lack integrated industrial sensor detection units, making it impossible to achieve integrated machining and detection operations. This has become a key bottleneck restricting the improvement of machining accuracy of core components of high-end metallurgical equipment. Summary of the Invention

[0011] Preferably, the height displacement detection component includes an axial guide and a detection component; the detection component includes a ranging reflector plate disposed on the bottom surface of the foot seat, and a laser emitter disposed on the side support plate, the laser emitter being disposed opposite to the ranging reflector plate.

[0012] Preferably, the axial guide includes a guide rod disposed on the foot seat and a bottom cylinder disposed on the side support plate. A guide cylinder is disposed inside the bottom cylinder, the guide rod is inserted into the guide cylinder, and the end of the guide rod inserted into the guide cylinder is connected to the bottom of the guide cylinder through an elastic element.

[0013] Preferably, the linear adjustment mechanism includes a lower base plate fixed to the bed, a side wall plate provided on the top surface of the lower base plate along its length, positioning seats provided at both the front and rear ends of the lower base plate, a front roller and a rear roller respectively provided on the front side of the two positioning seats, a motor provided on one side of the rear roller, the front roller and the rear roller respectively provided at both ends of the side wall plate, a belt rollingly connecting the front roller and the rear roller, a first slider fixed on the top surface of the belt, and the first slider slidably connected to the side wall plate.

[0014] Preferably, a base plate is fixed to the front end of the tailstock, and tail plates are provided on both sides of the top of the base plate. A first strip-shaped slot is opened on both sides of the base plate, and the tail plates are bolted through and connected to the first strip-shaped slot.

[0016] The beneficial effects of the present invention: By using the turning device for annealing furnace roller processing provided by the present invention, the following technical effects are achieved: 1. The coaxial detector is driven to move at a constant speed along the track by a linear adjustment mechanism. Combined with the rotation of the annealing furnace roller, it achieves full-range detection along the roller axis without blind spots, completely solving the problems of offline detection and partial missed detection in traditional devices. The height displacement detection component uses a laser emitter and a ranging reflector, which is far superior to traditional mechanical contact detection and can accurately capture the slight bending deformation of the roller. At the same time, the axial guide ensures that the fastener moves smoothly up and down without swaying, avoiding the distortion of detection data. It provides real-time and accurate deformation data support for turning, greatly reducing the rework rate caused by coaxiality deviation, shortening the processing cycle, and realizing the synchronous operation of turning and coaxiality measurement. It fills the technical gap of traditional turning machining centers without integrated industrial sensor detection units and greatly improves the precision machining capability of industrial machine tools.

[0017] 2. This device is adaptable to the processing needs of various industrial machine tools. At the tailstock, the first slot adjusts the tail plate spacing, and the second slot adjusts the slider height and the opening angle of the buckle plate, achieving multi-dimensional adjustment of the tail end receiving roller and side guard roller. It can accurately adapt to annealing furnace roller shafts of different diameters, forming a three-point flexible constraint, effectively preventing the roller from shifting and deviating during high-speed rotation. The front and rear receiving rollers of the middle support roller assembly work together to support the roller. With the height adjustable design of the pressure roller (fine-tuned by rotating the threaded column), it can adapt to rollers of different diameters within the range of 50-300mm. The pressure roller lightly touches the roller surface without applying excessive pressure, avoiding roller surface indentation. The design of the locking nut and positioning rod further ensures the stability of the pressure roller height and lateral limit, improving the reliability of support and detection. It can complete the processing of multiple specifications of rollers without replacing special parts, and has strong versatility.

[0018] 3. The fastener adopts a separate design of fastener cover and foot seat, and with the radial limit of positioning rod and positioning groove, it effectively prevents lateral displacement during operation; the guide rod of the axial guide component cooperates with the guide cylinder to ensure accurate vertical displacement of the fastener and avoid misalignment of the detection component due to vibration; the elastic component not only plays a buffering role, but also keeps the pressure roller in contact with the roller surface, improving detection sensitivity; the linear adjustment mechanism drives the slider to move horizontally through belt drive, and the operation is smooth and shock-free, reducing the impact of vibration on detection and processing, and ensuring that the device maintains stable and reliable performance during long-term operation.

[0019] 4. The cover and foot are detachably connected by fasteners. When components such as the pressure roller and laser emitter are worn or damaged, they can be disassembled and replaced individually without disassembling the entire testing assembly. This makes maintenance and operation convenient and reduces maintenance costs. All adjustment mechanisms of the device use detachable connections such as bolts and tightening screws. The structure is highly modular and does not require additional special adapter parts to meet the processing of multiple roller specifications, reducing the company's equipment investment costs and improving equipment utilization.

Detailed Implementation

[0022] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. The present invention discloses a turning device for machining annealing furnace rollers, comprising a machine bed, a track on the machine bed, a coaxial detector mounted on the track, and a base plate slidably connected to the track. A support roller assembly for supporting the workpiece is mounted on the base plate, the support roller assembly including a front support roller and a rear support roller, which support the bottom of the annealing furnace roller to assist in its rotation. A fastener is mounted on the top of a side support plate, the fastener including a fastener cover and feet located on both sides of the fastener cover. An adjustable pressure roller is mounted below the top of the fastener, and a height displacement detection assembly is mounted between the two ends of the fastener and the side support plate. When the annealing furnace roller undergoes a slight deformation and moves upward... When the pressure roller is lifted, the guide rod slides along the axial direction of the guide cylinder to ensure that the fastener moves smoothly and without swaying. This ensures that the laser emitter and the ranging reflector are always precisely aligned, and the ranging data accurately reflects the actual deformation of the roller surface, preventing measurement distortion caused by mechanical shaking or installation errors. The linear adjustment mechanism drives the coaxial detector to move at a constant speed along the track. Combined with the rotational movement of the annealing furnace roller, it achieves full-range detection without blind spots along the roller axis, completely solving the problems of offline detection and partial missed detection in traditional devices. The height displacement detection component uses a laser emitter and a ranging reflector to accurately capture the tiny bending deformation of the roller, providing real-time and accurate deformation data support for turning.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments; various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.

[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0025] like Figures 1-7 As shown in the figure, this embodiment discloses a turning device for processing annealing furnace rolls, including a bed 1, a track 3 provided on the bed 1, a chuck 2 provided at the end of the track 3, and a tailstock 4 provided at the top end of the track 3 away from the chuck 2; in addition, in this embodiment, a coaxial detector 5 is also provided on the track 3 for detecting the verticality of the middle part of the annealing furnace roll.

[0026] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the coaxial detector 5 in this embodiment includes a base plate 52 slidably connected to the track 3. A linear adjustment mechanism 51 is provided at the bottom of the bed 1 to drive the base plate 52 to move on the track 3. A support roller assembly for supporting the workpiece is provided on the base plate 52. A side support plate 57 is provided on the side of the support roller assembly. A fastener is provided on the top of the side support plate 57. An adjustable pressure roller 512 is provided below the top of the fastener. A height displacement detection component is provided between the two ends of the fastener and the side support plate 57. In actual operation, the first section of the annealing furnace roller is clamped by the chuck 2, the tail end is pressed by the tailstock 4, and the middle section is supported by the support roller assembly. The pressure roller 512 abuts against the top surface of the middle section. At this time, the base plate 52 is moved at a constant speed along the track 3 by the linear adjustment mechanism 51. When the annealing furnace roller bends, its bent part abuts against the pressure roller 512, causing the fastener to undergo a slight displacement. The height displacement detection component captures this displacement in real time and converts it into an electrical signal.

[0027] For example, such as Figure 5As shown, the linear adjustment mechanism 51 in this embodiment includes a lower base plate 5101 fixed to the bed 1. A side wall plate 5105 is provided on the top surface of the lower base plate 5101 along its length. Positioning seats 5106 are provided at both the front and rear ends of the lower base plate 5101. A front roller 5102 and a rear roller 5103 are respectively provided on the front side of the two positioning seats 5106. A motor 5104 is provided on one side of the rear roller 5103. The front roller 5102 and the rear roller 5103 are respectively located at both ends of the side wall plate 5105. A belt 5107 is rolled between wheel 5102 and rear roller 5103. A first slider 5108 is fixed on the top surface of belt 5107 and is slidably connected to side wall plate 5105. During operation, motor 5104 drives rear roller 5103 to rotate, which drives belt 5107 to move at a constant speed, thereby pushing first slider 5108 to move linearly along side wall plate 5105, so that base plate 52 moves forward synchronously and smoothly, and the height displacement detection component can continuously collect deformation data along the entire axis of annealing furnace roller.

[0028] In this embodiment, the aforementioned support roller assembly includes a front upright plate 53 located on the front side of the base plate 52 and a rear upright plate 55 located on the rear side of the base plate 52. Front support rollers 54 are rotatably connected to the left and right sides of the front upright plate 53, and rear support rollers 56 are rotatably connected to the left and right sides of the rear upright plate 55. The front support rollers 54 and the rear support rollers 56 support the bottom of the annealing furnace roller and assist the rotation of the annealing furnace roller. The aforementioned side support plate 57 is connected to the side of the front upright plate 53 and the rear upright plate 55.

[0029] In addition, the fastener in this embodiment includes a fastener cover 510 and feet 59 located on both sides of the fastener cover 510. The fastener cover 510 and feet 59 are designed separately. Specifically, the feet 59 and the fastener cover 510 are detachably connected by a fastener 516. The aforementioned height displacement detection component is located between the feet 59 and the side support plate 57.

[0030] A threaded post 511 is vertically threaded below the top of the cover 510, and a pressure roller 512 is rotatably connected to the bottom of the threaded post 511. The working height of the pressure roller 512 is adjusted by rotating the threaded post 511 to accurately fit annealing furnace rollers of different diameters, ensuring that the pressure roller 512 always lightly touches the surface without applying excessive pressure. A locking nut is also provided on the threaded post 511 to fix the height after adjustment and prevent displacement due to vibration during operation.

[0031] In addition, positioning rods 517 are provided on both sides of the bottom of the cover 510, and positioning grooves 518 are embedded in the top surface of the foot 59. The positioning rods 517 are inserted into the positioning grooves 518. After the cover 510 and the foot 59 are assembled, the positioning rods 517 and the positioning grooves 518 form a radial limit to ensure that the cover 510 does not shift laterally during operation.

[0032] The height displacement detection component in this embodiment includes an axial guide and a detection component. The axial guide is used to guide the vertical displacement of the fastener, and the detection component is used to detect the height of the fastener's upward movement. Specifically, the detection component includes a ranging reflector 519 disposed on the bottom surface of the foot 59, and a laser emitter 520 disposed on the side support plate 57. The laser emitter 520 is disposed opposite to the ranging reflector 519. The laser emitter 520 continuously emits pulse beams to the ranging reflector 519, collects the data on the change in the distance between the two in real time, and converts it into micron-level deformation values ​​on the surface of the annealing furnace roller through a built-in algorithm.

[0033] Specifically, the axial guide in this embodiment includes a guide rod 513 on the foot 59 and a bottom cylinder 58 on the side support plate 57. A guide cylinder 515 is provided inside the bottom cylinder 58. The guide rod 513 is inserted into the guide cylinder 515, and the end of the guide rod 513 inserted into the guide cylinder 515 is connected to the bottom of the guide cylinder 515 through an elastic member 514. During implementation, when the annealing furnace roller undergoes a slight deformation and pushes the pressure roller upward, the guide rod 513 slides axially along the guide cylinder 515 to ensure that the fastener moves upward smoothly without swaying, so that the laser emitter 520 and the ranging reflector 519 always maintain precise alignment, and the ranging data truly reflects the actual deformation of the roller surface, preventing measurement distortion caused by mechanical shaking or installation errors.

[0034] In this embodiment, as Figure 1 , Figure 6 and Figure 7 As shown, the front end of the tailstock 4 is fixed to the base plate 6 by bolts. Tail plates 8 are provided on both sides of the top of the base plate 6. The base plate 6 has a first strip slot 10 on both sides. The tail plates 8 are bolted through and connected to the first strip slot 10. The relative position of the tail plates 8 is adjusted according to the diameter of the shaft part at the end of the annealing furnace roller. During adjustment, the bolts move into the first strip slot 10. After adjustment, the nuts at the bottom of the bolts are tightened. The front end of the tail plate 8 is provided with a lug 7. The tail end receiving roller 9 is rotatably connected to the lug 7. The tail end receiving roller 9 is used to receive the shaft part at the end of the annealing furnace roller. The spacing of the tail end receiving roller 9 is adjusted by adjusting the relative distance of the tail plates 8 to adapt to the ends of annealing furnace rollers of different diameters and ensure that the shaft is centered and stably supported.

[0035] Furthermore, a tail plate 11 is provided on the top of the tail plate 8. The tail plate 11 is set vertically. A second strip-shaped slot 13 is opened horizontally on the tail plate 11. A second slider 12 is slidably connected to the second strip-shaped slot 13. A tightening screw is provided on the second slider 12. The second slider 12 can move within the second strip-shaped slot 13. After adjustment, the second slider 12 is locked by the tightening screw.

[0036] In addition, a connecting seat 14 is rotatably connected to the second slider 12. The connecting seat 14 is connected to the second slider 12 by screws. A buckle plate 15 is provided on the connecting seat 14, and a side guard roller 16 is provided on the inner side wall of the buckle plate 15. The opening and closing angle of the buckle plate 15 is adjusted according to the shaft part at the end of the annealing furnace roller of different diameters. The buckle plate 15 rotates and opens and closes with the connecting seat 14 as the axis. The side guard roller 16 deflects synchronously with it and always fits against the shaft surface to form a three-point flexible constraint. After the top screw is tightened, the second slider 12 is rigidly connected to the tail plate 11 to ensure that the opening and closing angle of the buckle plate 15 is accurately locked.

[0037] The working principle of this device is as follows: First, according to the diameter specifications of the annealing furnace roller to be processed, the device is adapted and adjusted: at the tailstock 4, the bolts in the first strip groove 10 are loosened, and the relative distance between the two tail plates 8 is adjusted so that the tail end receiving roller 9 is precisely attached to the bottom of the shaft at the end of the annealing furnace roller, and the bolts are tightened to fix the position of the tail plate 8; then, the top screws on the tail upright plate 11 are loosened, the second slider 12 is slid to adjust the height of the buckle plate 15, and then the buckle plate 15 is rotated around the connecting seat 14 as the axis, so that the side The guard roller 16 fits against the side of the shaft, forming a three-point flexible constraint of the tail end receiving roller and the two side guard rollers. Finally, the locking screw is tightened to fix the second slider 12, completing the central and stable support of the shaft end. Then, the first section of the annealing furnace roller is clamped in the chuck 2, the tail end is tightened by the tail seat 4, and the middle is placed on the top surface of the front receiving roller 54 and the rear receiving roller 56 of the support roller assembly. The front receiving roller 54 and the rear receiving roller 56 rotate to assist the subsequent synchronous rotation of the annealing furnace roller, avoiding bottom friction from affecting the processing accuracy. After the device is started, the chuck 2 drives the annealing furnace roller to rotate, and simultaneously activates the linear adjustment mechanism 51: the motor 5104 drives the rear roller 5103 to rotate, which in turn drives the first slider 5108 to move linearly at a constant speed along the side wall plate 5105 via the belt 5107. This, in turn, drives the base plate 52 and the supporting roller assembly and coaxial detector 5 to move along the track 3 in a direction away from the chuck 2, realizing full-process detection along the axis of the annealing furnace roller. During the translation process, if the annealing furnace roller has bending deformation, its protruding part will move upward. The push roller 512 drives the cover 510 and the foot 59 to move upward synchronously; at this time, the guide rod 513 slides smoothly along the axial direction of the guide cylinder 515, and the elastic element 514 is compressed to ensure accurate displacement direction; the laser emitter 520 captures the change in distance between itself and the ranging reflector 519 in real time, converts the change in distance into a micron-level roller surface deformation value through a built-in algorithm, and outputs it in the form of an electrical signal to realize real-time monitoring of the verticality of the middle part of the annealing furnace roller, providing data support for the precision adjustment of turning process; During processing, the front receiving roller 54 and the rear receiving roller 56 rotate synchronously with the annealing furnace roller, reducing the frictional resistance of the support part; the tail receiving roller 9 and the side guard roller 16 at the tail end always fit against the surface of the shaft, forming a stable constraint to prevent the annealing furnace roller from shifting or deviating when rotating at high speed; if it is necessary to replace the annealing furnace roller with one of different diameters, the fastener 516 can be disassembled to separate the cover 510 and the foot 59, and a suitable cover assembly can be replaced.
