Description

Technical Field

[0001] This invention belongs to the field of furnace roll processing technology, specifically relating to a furnace roll roughing turning equipment. Background Technology

[0002] A furnace roller is an auxiliary device used in industrial furnaces to support and transport materials or products. It is typically used in heat treatment, smelting, baking, and other processes under extreme conditions such as high temperature and high pressure. It is mainly composed of rollers, roller shafts, and reinforcing plates. The rollers, roller shafts, and reinforcing plates are often connected by welding. After welding, weld beads remain at the joints on the furnace roller. Therefore, during the rough machining of the furnace roller, the weld beads need to be machined to ensure the appearance of the furnace roller and to prevent the weld beads from affecting the normal use of the furnace roller.

[0003] In the process of turning furnace rolls, the rolls must first be clamped on a lathe, and then the joints of the rolls are turned using a cutting tool. The following problems exist in the current rough turning process of furnace rolls:

[0004] 1. Existing furnace roll roughing turning equipment has extremely limited operating space during furnace roll installation and removal. Due to the compact structure of the equipment, the operator's physical movement is greatly restricted when placing and fixing the furnace roll, which not only makes operation inconvenient but also increases the risk of operational errors. For example, when placing the furnace roll on the equipment, the limited space makes it difficult for the operator to accurately judge the position and angle of the furnace roll, which can easily lead to installation deviations and affect the subsequent processing accuracy. At the same time, during the installation and removal of the furnace roll, the furnace roll is very likely to interfere with and collide with other parts of the equipment, such as the turning mechanism. Such collisions may not only damage the equipment, leading to increased equipment maintenance costs and production interruptions, but may also damage the furnace roll itself, affecting the quality and service life of the furnace roll, thereby increasing production costs.

[0005] 2. The dimensions and specifications of furnace rolls vary significantly depending on production needs, including diameter and length. However, the support devices of existing furnace roll roughing turning equipment typically lack flexibility and are difficult to adapt to the support requirements of various furnace roll specifications. For example, when furnace rolls of different sizes need to be processed, the height of their central axes is inconsistent when placed on the same support device, causing interference when assembling with a three-jaw chuck. This often necessitates frequent replacement of the support device, which is not only cumbersome and time-consuming, reducing production efficiency, but also increases equipment and operating costs.

[0006] Therefore, there is an urgent need to design a furnace roll roughing turning device to improve the above problems. Summary of the Invention

[0026] (3) Beneficial effects

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. The present invention, through the setting of a support platform, Y-axis guide rail and X-axis guide rail, allows the movable base to be smoothly moved from the mounting cavity of the frame to the support platform via the Y-axis guide rail before the furnace roller is installed. At this time, the movable base is away from the frame, providing a spacious and interference-free space for the installation of the furnace roller. Operators can perform the placement and fixing of the furnace roller more conveniently and safely, improving the convenience and safety of operation and reducing operational errors caused by limited space.

[0029] 2. This invention, through the receiving component and angle adjustment structure within the furnace roller support mechanism, allows for the synchronous adjustment of the angles of the two supporting rotating plates when installing furnace rollers of different sizes. This adjustment, in turn, adjusts the position of the bearing roller, ensuring that the central axis of furnace rollers of different sizes is located in the same position. This provides a good foundation for the accurate docking of the furnace roller with the three-jaw chuck on the spindle box and for subsequent turning operations. It also helps improve the accuracy and quality of the rough machining of the furnace roller. The angle adjustment structure can adjust the positions of the supporting rotating plates and the bearing roller according to different sizes of furnace rollers, enabling the furnace roller support mechanism to adapt to the support requirements of various specifications of furnace rollers. This eliminates the need for frequent replacement of support devices, improves the versatility and applicability of the equipment, and reduces equipment and operating costs.

[0030] 3. This invention, through the axial limiting mechanism of the furnace roller, provides a clear end position reference for the furnace roller. Operators can quickly and accurately place the furnace roller in the appropriate position based on the position of the furnace roller end limiting plate, aligning the axial center of the furnace roller with the preset center line of the equipment. This ensures the initial position accuracy of the furnace roller installation, reducing the workload and time of subsequent adjustments. The spacing adjustment component is used to simultaneously adjust the positions of the two moving plates, thereby simultaneously adjusting the positions of the two furnace roller end limiting plates, adapting to the use of furnace rollers of different lengths. Through the folding and unfolding component, when the mounting plate is moved into the mounting cavity of the frame, it drives the furnace roller end limiting plate to rotate around the second connecting seat, adjusting the furnace roller end limiting plate to a vertically folded position, thus offsetting the furnace roller end limiting plate from the furnace roller and avoiding affecting the fixation of the furnace roller with the three-jaw chuck on the main shaft box and tailstock.

[0050] This specific embodiment is a furnace roll roughing turning device, the structural schematic diagram of which is shown below. Figures 1-10As shown, the furnace roll roughing turning equipment includes a frame 1. A spindle box 2 is located at one end of the top of the frame 1 and is fixedly mounted on the frame 1. A tailstock 3 is located at the other end of the top of the frame 1 and is mounted on the frame 1 via an X-axis moving module. Three-jaw chucks for fixing the furnace roll are located on opposite sides of the spindle box 2 and the tailstock 3. A turning mechanism 4 is also located at the top of the frame 1 between the spindle box 2 and the tailstock 3 and is also mounted on the frame 1 via an X-axis moving module. During operation, one end of the furnace roll to be roughed is placed in the three-jaw chuck on the spindle box 2, and the clamping action of the three-jaw chuck fixes one end of the furnace roll. Then, the tailstock 3 is moved. Bring the three-jaw chuck on the tailstock 3 close to the other end of the furnace roller and clamp it to achieve stable installation of the furnace roller on the equipment. Adjust the position of the turning mechanism 4 so that its tool is aligned with the part of the furnace roller that needs to be processed. Set the turning parameters according to the processing requirements, such as the depth of cut and feed rate. Start the equipment. The spindle box 2 drives the furnace roller to rotate. At the same time, the turning mechanism 4 performs feed motion according to the set parameters to cut the surface of the rotating furnace roller, remove excess material, and gradually process the furnace roller to the required size and shape. It should be noted that the spindle box 2, tailstock 3, three-jaw chuck, turning mechanism 4 and X-axis moving module are all existing technologies and will not be described in detail here.

[0051] In this embodiment, as Figure 2 and Figure 3 As shown, the furnace roll roughing turning equipment also includes a movable base 5, a mounting plate 6, and a furnace roll support mechanism 7. The mounting plate 6 is located above the movable base 5. A position adjustment structure is provided between the mounting plate 6 and the movable base 5, and between the movable base 5 and the frame 1. A mounting cavity 101 is opened at the rear end of the top of the frame 1 to accommodate the movable base 5. A bearing platform 102 corresponding to the mounting cavity 101 is provided on the back of the frame 1. The top surface of the bearing platform 102 and the bottom surface inside the mounting cavity 101 are on the same horizontal plane. The position adjustment structure includes a Y-axis guide rail 501 set between the movable base 5, the mounting cavity 101, and the bearing platform 102. The position adjustment structure also includes an X-axis guide rail 502 set between the mounting plate 6 and the movable base 5. The Y-axis guide rail 501 and the X-axis guide rail 502 can be high-precision electric linear guide rails.

[0052] Before installing the furnace roller, the movable base 5 is smoothly moved from the mounting cavity 101 of the frame 1 to the support platform 102 via the Y-axis guide rail 501. Since the top surface of the support platform 102 and the bottom surface inside the mounting cavity 101 are on the same horizontal plane, the movable base 5 can maintain a stable state during the movement. At this time, the movable base 5 is away from the frame 1, providing a spacious and uninterrupted space for the installation of the furnace roller. The operator places the furnace roller on the furnace roller support mechanism 7 of the movable base 5 on the support platform 102 and fixes it. The furnace roller support mechanism 7 can stably support the furnace roller, ensuring that the furnace roller will not shift or shake during subsequent movement. After the furnace roller is fixed on the furnace roller support mechanism 7, the Y-axis guide rail 501 is started again to smoothly move the movable base 5, together with the furnace roller support mechanism 7 and the furnace roller, back to the mounting cavity of the frame 1. Inside cavity 101, the mounting plate 6 is precisely adjusted in the X-axis direction using the X-axis guide rail 502, ensuring that one end of the furnace roller accurately aligns with the three-jaw chuck on the spindle box 2. The fine-tuning function of the X-axis guide rail 502 guarantees the accuracy of the alignment and ensures the accuracy of the furnace roller installation. During the installation and removal of the furnace roller, the movable base 5 is moved onto the support platform 102, keeping the furnace roller away from the frame 1. This effectively avoids interference and collisions with other components on the frame 1, such as the turning mechanism 4, during the installation and removal of the furnace roller, protecting the safety of the equipment and the furnace roller, and reducing the risk of equipment damage and furnace roller injury. The support platform 102 provides a relatively spacious operating space for the installation of the furnace roller, allowing operators to place and fix the furnace roller more conveniently and safely, improving the convenience and safety of operation, and reducing operational errors caused by limited space.

[0053] In this embodiment, as Figure 4 and Figure 10As shown, the furnace roller support mechanism 7 is installed on the top of the mounting plate 6 to support and fix the furnace roller. The furnace roller support mechanism 7 includes two sets of receiving components. The receiving components include a first connecting seat 701 fixedly connected to the top of the mounting plate 6 and two supporting rotating plates 702 rotatably connected inside the first connecting seat 701. The two supporting rotating plates 702 are V-shaped. The top of each supporting rotating plate 702 is rotatably connected to a bearing roller 703. The receiving components also include an angle adjustment structure, which is used to adjust the angle of the supporting rotating plates 702 so that when the receiving components support and fix furnace rollers of different sizes, the central axis of the furnace rollers is located in the same position. When installing the furnace roller, the furnace roller is moved and placed inside the two supporting rotating plates 702 of the two sets of receiving components by a hoisting device, so that the furnace roller contacts the bearing roller 703 for support. In addition, during the rough machining of the furnace roller, the bearing roller 703 is used to support the furnace roller. The coordination facilitates the rotational processing of the furnace rollers. When installing furnace rollers of different sizes, the angle adjustment structure synchronously adjusts the angles of the two supporting rotating plates 702, thereby adjusting the position of the bearing roller 703. This ensures that the central axis of the furnace rollers of different sizes is located in the same position, providing a good foundation for the accurate docking of the furnace rollers with the three-jaw chuck on the spindle box 2 and for turning processing. It is beneficial to improve the accuracy and quality of the rough machining of the furnace rollers. The angle adjustment structure can adjust the position of the supporting rotating plate 702 and the bearing roller 703 according to the furnace rollers of different sizes, so that the furnace roller support mechanism 7 can adapt to the support requirements of various specifications of furnace rollers without frequent replacement of support devices. This improves the versatility and applicability of the equipment and reduces equipment and operating costs.

[0054] In this embodiment, as Figure 4 and Figure 5As shown, the angle adjustment structure includes a support plate 706 rotatably connected to the bottom of the support rotating plate 702. A movable hinge seat 705 is rotatably connected to the bottom of the support plate 706. A slide rail 704 is fixedly connected to the top of the mounting plate 6 along the Y-axis. The movable hinge seat 705 is slidably connected to the slide rail 704. A rack 707 is fixedly connected to one side of each of the two movable hinge seats 705, and the rack 707 is slidably connected to the slide rail 704. A rotating shaft 708 is rotatably connected to the top of the mounting plate 6, located between the two racks 707. The top of the rotating shaft 708... A gear 709 is fixedly connected, meshing with two racks 707. The angle adjustment structure also includes a first drive component 711 mounted on the top of the mounting plate 6. The output end of the first drive component 711 is fixedly connected to a connecting plate 710. Both ends of the connecting plate 710 are respectively fixedly connected to one of the movable hinge seats 705 of the two sets of receiving components. It should be noted that the first drive component 711 can be a hydraulic cylinder, electric push rod, etc., as long as it can realize the movement of the connecting plate 710 along the Y-axis direction. When adjustment according to the size of the furnace roller is required... When the angle of the supporting rotating plate 702 is adjusted, the first driving member 711 is activated. The first driving member 711 drives the connecting plate 710 to move along the Y-axis. The connecting plate 710 pushes the movable hinge seat 705 connected to it to move along the slide rail 704. As one of the movable hinge seats 705 moves, the rack 707 fixed on it moves accordingly. Through the gear 709, it meshes with the two racks 707. The movement of the rack 707 will drive the gear 709 to rotate, and the rotation of the gear 709 will cause the other rack 707 to move in the opposite direction. This, in turn, drives another movable hinge seat 705 to move synchronously in the opposite direction. When the movable hinge seat 705 moves on the slide rail 704, it pushes or pulls the support plate 706, thereby causing the support rotating plate 702 to rotate around the connection point on the first connecting seat 701, realizing the adjustment of the angle of the support rotating plate 702. The support plate 706 and the support rotating plate 702 form a triangular structure, which improves the structural stability, thereby adjusting the position of the bearing roller 703 to meet the support requirements of different specifications of furnace rollers, and improving the adaptability and processing accuracy of the equipment.

[0055] As a preferred embodiment of this example, an angle indicator can be provided on the first connecting seat 701. The angle indicator can be an existing device with mature technology such as an electronic tilt sensor or a laser angle measuring instrument. When adjusting the angle of the support rotating plate 702, the angle indicator can display the angle value of the support rotating plate 702 in real time and accurately. During the angle adjustment process of the support rotating plate 702, the operator can accurately grasp the rotation angle of the support rotating plate 702 by observing the angle indicator, so as to more accurately adjust the support rotating plate 702 to the required angle to meet the support requirements of furnace rollers of different sizes and ensure the stable and accurate support of the furnace roller support mechanism 7 for the furnace roller.

[0056] In this embodiment, as Figure 4 As shown, the furnace roller support mechanism 7 also includes a clamping assembly located between the two sets of receiving components. The clamping assembly includes a support frame 712 fixedly connected to the top of the mounting plate 6. A first guide rod 713 is vertically fixedly connected inside the support frame 712. A lifting plate 715 is slidably sleeved on the first guide rod 713. A second driving member 714 is installed on the top of the support frame 712. The output end of the second driving member 714 extends into the support frame 712 and is fixedly connected to the lifting plate 715. The second driving member 714 can be a hydraulic cylinder, electric cylinder, or other similar device. The actuator, such as the push rod, only needs to enable the lifting plate 715 to move along the Z-axis. A third drive component 716 is mounted on the top of the lifting plate 715, and a pressure roller plate 717 is fixedly connected to the output end of the third drive component 716. The third drive component 716 can be a rotary cylinder, servo motor, etc., and only needs to enable the pressure roller plate 717 to rotate horizontally by 90°. The pressure roller plate 717 has an inverted V-shaped structure, and pressure rollers 718 are rotatably connected to both sides of the bottom of the pressure roller plate 717. The furnace roller is then installed onto the furnace roller support mechanism 7. Before the furnace rollers are placed on the receiving assembly, the pressure roller plate 717 is in its initial position, which is the highest position, and the pressure roller plate 717 is offset from the receiving assembly. At this time, the pressure roller plate 717 is perpendicular to the supporting rotating plate 702, thus leaving enough space for the placement of the furnace rollers. After the furnace rollers are placed on the receiving assembly, the third driving member 716 drives the pressure roller plate 717 to rotate horizontally by 90°, making the pressure roller plate 717 parallel to the supporting rotating plate 702. Then, the second driving member 714 drives the lifting plate to move. 715 moves vertically downward along the first guide rod 713, thereby driving the pressure roller plate 717 to descend synchronously. The pressure roller 718 presses tightly against the surface of the furnace roller, generating sufficient pressure to firmly fix the furnace roller on the receiving assembly, ensuring that the furnace roller will not shift or wobble during subsequent turning processes. Through the inverted V-shaped structure of the pressure roller plate 717, the pressing assembly can adapt to furnace rollers of different diameters. No matter how the size of the furnace roller changes, the pressure roller 718 can be adjusted to accurately press the furnace roller, improving the versatility of the equipment.

[0057] In this embodiment, as Figure 6As shown, the furnace roller axial limiting mechanism 8 includes two movable plates 801. The mounting plate 6 has receiving grooves 601 at both ends of its bottom along the X-axis. The movable plates 801 are slidably installed inside the receiving grooves 601. The top of the mounting plate 6 has a through groove 602 communicating with the receiving grooves 601. The top portion of the movable plate 801 passes through the through groove 602 and is fixedly connected to a second connecting seat 802. A furnace roller end limiting plate 803 is rotatably connected inside the second connecting seat 802. The furnace roller axial limiting mechanism 8 also includes a spacing adjustment assembly and... The folding and unfolding assembly and the spacing adjustment assembly are used to synchronously adjust the positions of the two furnace roll end limiting plates 803. The folding and unfolding assembly is used to drive the furnace roll end limiting plates 803 to fold / unfold in the horizontal / vertical direction. The two moving plates 801 are located outside the furnace roll support mechanism 7. When the furnace roll is placed on the furnace roll support mechanism 7, the furnace roll end limiting plates 803 provide a clear end position reference for the furnace roll. The operator can quickly and accurately place the furnace roll according to the position of the furnace roll end limiting plates 803. The appropriate position ensures that the axial center of the furnace roller is aligned with the preset center line of the equipment, guaranteeing the initial positional accuracy of the furnace roller installation and reducing the workload and time required for subsequent adjustments. During installation, the furnace roller may experience axial displacement due to operational actions or external factors. The furnace roller end limiting plate 803 can block the furnace roller end, effectively preventing axial sliding or displacement during installation, ensuring the stability and accuracy of the furnace roller installation, and laying a good foundation for subsequent processing operations. The spacing adjustment component is used to synchronously adjust the positions of the two moving plates 801, thereby synchronously adjusting the positions of the two furnace roller end limiting plates 803, adapting to furnace rollers of different lengths for use. Through the folding and unfolding component, when the mounting plate 6 is moved into the mounting cavity 101 of the frame 1, the furnace roller end limiting plate 803 is driven to rotate around the second connecting seat 802, adjusting the furnace roller end limiting plate 803 to a horizontal folded position, and offsetting the furnace roller end limiting plate 803 from the furnace roller, avoiding affecting the fixing of the furnace roller to the three-jaw chuck on the main shaft box 2 and tailstock 3.

[0058] In this embodiment, as Figure 6As shown, the spacing adjustment assembly includes a lead screw 804 and a second guide rod 805 disposed at both ends of the top of the mounting plate 6 along the X-axis. Both ends of the lead screw 804 are mounted on the mounting plate 6 via bearing seats, and both ends of the second guide rod 805 are mounted on the mounting plate 6 via fixing plates. The two ends of the lead screw 804 are provided with threads of opposite directions, and adjusting plates 806 are threadedly connected to the threads of the lead screw 804 of opposite directions. One end of the adjusting plate 806 is slidably connected to the second guide rod 805. The two adjusting plates 806 are respectively fixedly connected to two moving plates 801. The spacing adjustment assembly also includes a power component for driving the lead screw 804 to rotate. The power component can be a servo motor with a gear set, which only needs to rotate the lead screw 804. When limiting furnace rollers of different lengths, the power component drives the lead screw 804 to rotate, thereby adjusting the position of the two adjusting plates 806 along the axial direction of the lead screw 804. The two adjusting plates 806 can move closer or further away from each other synchronously. When adjusting, the adjusting plates 806 slide on the second guide rod 805, which plays a limiting and guiding role and improves the stability of movement. Thus, the adjusting plates 806 drive the moving plate 801 and the furnace roller end limiting plate 803 to adjust their positions to adapt to furnace rollers of different lengths for limiting use during installation.

[0059] In this embodiment, as Figure 7 , Figure 8 and Figure 9As shown, the folding and unfolding assembly includes two guide holes along the length of the moving plate 801. A third guide rod 807 is slidably installed within the guide holes. A fixing plate 810 is fixedly connected to one end of the two third guide rods 807 near the frame 1. A third connecting seat 808 is fixedly connected to the other end of the two third guide rods 807. A driving plate 809 is movably hinged between the third connecting seat 808 and the furnace roller end limiting plate 803. A groove 800 communicating with the two guide holes is provided at the bottom of the moving plate 801. 011, a connecting plate 811 is fixedly connected between the two third guide rods 807 at the groove 8011. A reset member 812 is fixedly connected between the side of the connecting plate 811 away from the fixed plate 810 and the inner wall of the groove 8011. The reset member 812 can be a damping spring, etc., as long as it can realize the reset function of the connecting plate 811. When the mounting plate 6 moves into the mounting cavity 101 of the frame 1, the fixed plate 810 will first contact the inner wall of the mounting cavity 101 of the frame 1, applying a force to the fixed plate 810. A force is applied along the length of the moving plate 801 in a direction away from the frame 1. The two third guide rods 807 move along the guide holes on the moving plate 801. The third guide rods 807 drive the third connecting seat 808 away from the mounting plate 6, thereby pulling the furnace roller end limiting plate 803 from vertical to horizontal via the driving plate 809. This folds the furnace roller end limiting plate 803, misaligning it with the furnace roller to avoid affecting the fixing of the furnace roller to the three-jaw chuck on the main shaft box 2 and tailstock 3. When the mounting plate 6 moves... When the roller moves onto the bearing platform 102, the resetting component 812 pushes the connecting plate 811 to reset the third guide rod 807, thereby resetting the third connecting seat 808. The driving plate 809 pushes the furnace roller end limiting plate 803 from horizontal to vertical, realizing the unfolding of the furnace roller end limiting plate 803. This continues to limit the furnace rollers to be processed later, allowing the furnace roller end limiting plate 803 to unfold or fold automatically without the need for manual operation by the operator, saving time and manpower and improving overall work efficiency.

[0060] In this embodiment, telescopic protective covers are provided on both sides of the movable plate 801 placed inside the through groove 602 and between the inner wall of the through groove 602 to prevent the entry of processing debris.

[0061] Working principle: When using the furnace roll roughing turning equipment of this technical solution, the movable base 5 is smoothly moved from the mounting cavity 101 of the frame 1 to the bearing platform 102 through the Y-axis guide rail 501, providing a spacious and interference-free space for the installation of the furnace roll;

[0062] Adjust the furnace roll support mechanism 7 according to the size of the furnace roll to be rough-machined, and start the first drive member 711. The first drive member 711 drives the connecting plate 710 to move along the Y-axis. The connecting plate 710 pushes the movable hinge seat 705 connected to it to move along the slide rail 704. As one of the movable hinge seats 705 moves, the rack 707 fixed on it moves accordingly. It meshes with the two racks 707 through the gear 709. The movement of the rack 707 will drive the gear 709 to rotate. The rotation of the gear 709 will cause the other rack 707 to move in the opposite direction, thereby driving the other movable hinge seat 705 to move synchronously in the opposite direction. When the movable hinge seat 705 moves on the slide rail 704, it will push or pull. The support plate 706 allows the support rotating plate 702 to rotate around the connection point on the first connecting seat 701, thereby adjusting the angle of the support rotating plate 702. After adjusting the support rotating plate 702 to a suitable position, the furnace roller is moved and placed inside the two support rotating plates 702 of the two sets of supporting components by the hoisting equipment, so that the furnace roller contacts the bearing roller 703 for support. The angle adjustment structure can adjust the position of the support rotating plate 702 and the bearing roller 703 according to the furnace roller of different sizes, so that the furnace roller support mechanism 7 can adapt to the support requirements of various specifications of furnace rollers, without the need for frequent replacement of support devices, improving the versatility and applicability of the equipment, and reducing equipment cost and operating cost.

[0063] When the furnace roller is placed on the furnace roller support mechanism 7, the furnace roller end limiting plate 803 provides a clear end position reference for the furnace roller. The operator can quickly and accurately place the furnace roller in the appropriate position according to the position of the furnace roller end limiting plate 803, so that the axial center of the furnace roller is aligned with the preset center line of the equipment, ensuring the initial position accuracy of the furnace roller installation. The power component drives the lead screw 804 to rotate, thereby adjusting the position of the two adjusting plates 806 along the axial direction of the lead screw 804. The two adjusting plates 806 can move closer to each other or move further away from each other simultaneously. Thus, the adjusting plates 806 drive the moving plate 801 and the furnace roller end limiting plate 803 to adjust their positions to accommodate furnace rollers of different lengths for limiting use during installation.

[0064] After the furnace roller is placed on the receiving assembly, the third driving component 716 drives the pressure roller plate 717 to rotate horizontally by 90°, so that the pressure roller plate 717 is parallel to the supporting rotating plate 702. Then, the second driving component 714 drives the lifting plate 715 to move vertically downward along the first guide rod 713, thereby driving the pressure roller plate 717 to descend synchronously. The pressure roller 718 presses tightly against the surface of the furnace roller, generating sufficient pressure to firmly fix the furnace roller on the receiving assembly, ensuring that the furnace roller will not shift or shake during the subsequent turning process.

[0065] After the furnace roller is fixed on the furnace roller support mechanism 7, the Y-axis guide rail 501 is restarted to smoothly move the movable base 5, along with the furnace roller support mechanism 7 and the furnace roller, back into the mounting cavity 101 of the frame 1. The fixing plate 810 will first contact the inner wall of the mounting cavity 101 of the frame 1, applying a force along the length of the movable plate 801 away from the frame 1. The two third guide rods 807 move along the guide holes on the movable plate 801. The third guide rods 807 drive the third connecting seat 808 away from the mounting plate 6, thereby pulling the furnace roller end limiting plate 803 from the vertical position via the driving plate 809. The furnace roller end limiting plate 803 is folded horizontally to offset it from the furnace roller. Then, the mounting plate 6 is precisely adjusted in the X-axis direction via the X-axis guide rail 502 so that one end of the furnace roller is accurately aligned with the three-jaw chuck on the spindle box 2. The tailstock 3 is moved so that the three-jaw chuck on the tailstock 3 is close to the other end of the furnace roller and clamped, thus achieving stable installation of the furnace roller on the equipment. The position of the turning mechanism 4 is adjusted so that its cutting tool is aligned with the part of the furnace roller that needs to be processed. The spindle box 2 drives the furnace roller to rotate, and at the same time, the turning mechanism 4 performs a feed motion according to the set parameters to cut the surface of the rotating furnace roller.

[0066] The control method of the present invention is controlled by the controller of the furnace roll roughing turning equipment. The control program of the controller can be implemented by those skilled in the art through simple programming. Therefore, the control method and circuit connection will not be explained in detail in the present invention.

[0067] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
