Description

Technical Field

[0001] The present invention relates to the technical field of roller installation, in particular to a workbench roller installation device. Background Art

[0002] During the production and assembly of workbenches, roller installation is a critical and routine process. Its quality and efficiency directly impact the overall performance and production progress of the workbench. However, the current workbench roller installation process has long faced numerous challenges. Traditional installation methods require extremely high working conditions and personnel coordination, and cannot guarantee stable installation results.

[0003] Specifically, the problem of lifting is particularly prominent. Because there is usually a pad above the workbench roller, conventional lifting tools cannot be used directly. A single roller often needs to be transported and installed by manpower. For the installation of rollers on a multi-station workbench, a crane is required. This reliance on manpower or a crane is not only physically demanding, but also poses serious safety hazards. During the handling or lifting process, the rollers are very easy to fall off. Moreover, the workbench's long-term lifting rings also have the risk of slipping, which also greatly reduces installation efficiency.

[0004] Furthermore, it is even more difficult to control the installation positioning accuracy. In the absence of special tooling assistance, ensuring the coaxiality of the roller and the rotating shaft, as well as the embedding of the positioning key, depends entirely on the operator's experience, and usually requires adjustment by evenly tapping with a copper hammer. This process not only requires a high degree of coordination between the crane and the fitter, which increases the complexity of the operation, but also poses a safety risk due to the uncertainty of manual adjustment, resulting in low installation efficiency. In addition, the cleaning and oiling processes cannot be completed in one go. The weight of a single roller can reach 48Kg, and it requires the joint efforts of multiple people to flip it over for comprehensive cleaning and oiling. This not only poses the risk of squeezing and injuring people, but also easily causes anti-rust oil pollution, further restricting the improvement of installation efficiency. In summary, the existing workbench roller installation method has obvious defects in safety, accuracy and efficiency, and a reliable solution is urgently needed. Summary of the Invention

[0005] In view of the current problems of poor coaxiality between the roller and the rotating shaft, and the reliance on the operator's experience when embedding the positioning key, which leads to low installation efficiency, the present invention provides a workbench roller installation device.

[0006] In order to solve the above problems, the technical solution adopted by the present invention is:

[0007] A workbench roller mounting device includes a fixing frame for placing a roller, the fixing frame being mounted on a lifting mechanism; the workbench roller mounting device also includes a guide pin that can be mounted on the end of the roller's rotating shaft. By providing a fixing frame for placing the roller, the workbench roller mounting device can stably fix the roller, avoiding the risk of squeezing during manual handling and flipping, and facilitates comprehensive cleaning and oiling in a fixed state, eliminating anti-rust oil contamination. The fixing frame is mounted on the lifting mechanism, facilitating coaxiality adjustment. The lifting function can easily adjust the roller height so that it is quickly aligned with the mounting shaft, reducing labor consumption and the risk of falling off, and improving the safety of handling and installation. The guide pin mounted on the end of the roller's rotating shaft can guide the roller into position, ensuring coaxiality, and facilitates the insertion of a positioning key, reducing tapping adjustments, significantly shortening installation time, and effectively solving the problems of poor safety, low accuracy, and low efficiency in existing installation methods.

[0008] Preferably, a tapered surface is provided at the outer edge of one end of the guide pin; a stepped hole is coaxially provided on the guide pin; the large-diameter end of the stepped hole is provided at one end of the tapered surface on the guide pin; and a plurality of key slots are evenly provided along the circumferential direction on the outer wall of the guide pin. The tapered surface at the outer edge of one end of the guide pin can guide the roller to dock with the installation shaft more smoothly, reducing the difficulty of initial alignment; the coaxial stepped hole not only reduces the weight of the guide pin itself for easy operation, but also provides space for bolt connection. The guide pin can be firmly connected to the rotating shaft through the bolts in the stepped hole, making assembly and disassembly convenient and the connection reliable; the plurality of key slots evenly provided along the circumferential direction on the outer wall can quickly match positioning keys of different angles, greatly reducing the adjustment time when the positioning key is embedded, further improving positioning accuracy. The overall structural design effectively enhances the practicality and stability of the guide pin, helping to improve installation efficiency and quality.

[0009] Preferably, the fixing frame includes a channel steel; mounting plates are fixedly provided on both sides of the bottom surface of the channel steel; the mounting plates are installed on the lifting mechanism; two angle steels are provided opposite to each other at both ends of the channel steel; and the angle steels are fixed to the mounting plates.

[0010] Preferably, the bottom surface of each mounting plate is fixedly provided with a connecting block; the connecting block is fixedly mounted on the lifting mechanism. The connecting block fixed to the bottom surface of the mounting plate can form a stable transition connection between the mounting plate and the lifting mechanism, further enhancing the reliability of the connection between the fixing frame and the lifting mechanism and avoiding the looseness that may occur due to a direct connection. Furthermore, the connecting block can be flexibly adjusted according to the installation dimensions of the lifting mechanism, improving the compatibility of the fixing frame with different types of lifting mechanisms, making the fixing frame installation more flexible and convenient, and providing more reliable structural support for the stable placement and precise adjustment of the rollers.

[0011] Preferably, the mounting plate is slidingly arranged on the lifting mechanism; the workbench roller mounting device also includes a translation drive mechanism; the translation drive mechanism is arranged on the lifting mechanism, and the translation drive mechanism is used to push the fixed frame on which the roller is placed to translate along the axis of the rotating shaft. The mounting plate is slidingly arranged on the lifting mechanism, and cooperates with the translation drive mechanism arranged on the lifting mechanism to push the fixed frame on which the roller is placed to translate smoothly along the axis of the rotating shaft, and can adjust the axial distance between the roller and the rotating shaft. There is no need to manually push the fixed frame to fine-tune the position, which reduces manpower consumption; this design enables the roller to further control the axial position after the height is adjusted, ensuring more precise docking between the roller and the rotating shaft, reducing bumps and jams during the installation process, effectively improving the smoothness and accuracy of the installation, and further improving the overall installation efficiency.

[0012] Preferably, the lifting mechanism is provided with a guide rail; a slider is slidably provided on the guide rail; and the slider is mounted on the bottom surface of the mounting plate. The guide rail provided on the lifting mechanism cooperates with the slider on the bottom surface of the mounting plate to provide guidance for the translation of the fixed frame, effectively constraining the translation trajectory of the fixed frame, avoiding offset or shaking during translation, and ensuring that the fixed frame slides smoothly along the axis of the rotating shaft. This sliding cooperation method has low friction resistance, making the translation of the fixed frame smoother and more labor-saving, reducing the load on the translation drive mechanism, and at the same time improving the accuracy of position adjustment, further ensuring the accuracy of the docking of the roller and the rotating shaft, and laying a solid foundation for efficient and precise installation of the roller.

[0013] Preferably, the translation drive mechanism includes a base plate; a telescopic assembly is fixedly mounted on the base plate; a push plate is connected to the output end of the telescopic assembly; and one side of the push plate can abut against two angle steels and a channel steel. In the translation drive mechanism, the base plate provides solid support for the entire mechanism, ensuring the stability of the telescopic assembly during operation; the push plate connected to the output end of the telescopic assembly, by abutting against the two angle steels and the channel steel, can evenly apply thrust to the fixed frame, so that the force on the fixed frame is balanced, avoiding deformation or offset of the fixed frame due to excessive local force, and ensuring smooth and precise translation of the fixed frame along the guide rail; this structural design can achieve effective drive and control of the translation of the fixed frame, further improve the accuracy and efficiency of the docking between the roller and the rotating shaft, reduce the need for manual intervention, and enhance the practicality and reliability of the device.

The telescopic assembly uses an electric push rod, oil cylinder, or pneumatic cylinder, and the power source can be flexibly selected according to the actual working conditions, thereby improving the adaptability and practicality of the device; the cylinder fixed on one side of the push plate can form a wrapping limit for the output end of the telescopic assembly, ensuring the accurate direction of thrust transmission and preventing the output end of the telescopic assembly from deviating and affecting the force on the push plate; the number of reinforcing ribs between the side wall of the cylinder and the push plate enhances the structural strength of the connection between the cylinder and the push plate, preventing deformation or breakage when subjected to force, ensuring the stable transmission of thrust to the fixed frame, further improving the reliability and stability of the translation drive mechanism, and facilitating the efficient and smooth installation of the power roller.

[0015] Preferably, the workbench roller mounting device further includes a centering mechanism; the centering mechanism includes a cross slot provided on the push plate; the cross slot is provided on the side of the push plate away from the cylinder; the centering mechanism further includes a fixing block; the fixing block can be placed on the large diameter end in the stepped hole; the fixing block is coaxially provided with a through hole; a flashlight is placed in the through hole. In the centering mechanism, the cross slot on the side of the push plate away from the cylinder can be used as a visual alignment reference to help the operator quickly determine the alignment status of the roller and the rotating shaft; the fixing block can be stably placed in the stepped hole, and its coaxially provided through hole provides an installation space for the flashlight, and the light emitted by the flashlight can be emitted along the axial direction, and by cooperating with the cross slot, a clear optical alignment reference is formed, which facilitates the operator to intuitively observe the coaxiality of the roller and the rotating shaft, greatly reducing the centering adjustment time, and further ensuring the installation quality and efficiency.

[0016] Preferably, a disc is provided on one side of the fixed block via a connecting rod; a cross-hole is fixedly provided in the middle of the disc. The disc provided on one side of the fixed block via the connecting rod, in conjunction with the cross-hole in the middle of the disc, can form a multi-level optical alignment reference with the cross slot on the push plate. After the flashlight light passes through the through-hole of the fixed block, it forms a precise beam through the cross-hole of the disc, which corresponds to the cross slot of the push plate, further reducing the alignment error and allowing the operator to more clearly judge the coaxiality of the roller and the rotating shaft. At the same time, when the fixed block is placed in the stepped hole, the cross-hole is used to correspond to the keyway of the roller, facilitating the subsequent insertion of the key bar in the keyway.

[0017] It can be seen from the above technical solutions that the advantages of the present invention include: the workbench roller installation device can stably fix the roller by setting a fixed frame for placing the roller, avoiding the hidden danger of extrusion during manual handling and flipping, and is convenient for completing comprehensive cleaning and oiling in a fixed state, eliminating anti-rust oil pollution; the fixed frame is installed on the lifting mechanism, which is convenient for adjusting the coaxiality.

DETAILED DESCRIPTION

[0032] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0033] Example 1

[0034] like Figure 1 and Figure 2 As shown, a workbench roller mounting device includes a fixing frame 2 for placing a roller 1, and is characterized in that the fixing frame 2 is mounted on a lifting mechanism 10; the workbench roller mounting device also includes a guide pin 4 that can be mounted on the end of the rotating shaft 3 of the roller 1.

[0035] The workbench roller installation device can stably fix the roller 1 by providing a fixing frame 2 for placing the roller 1, avoiding the risk of squeezing during manual handling and flipping, and facilitating comprehensive cleaning and oiling in a fixed state to prevent anti-rust oil pollution; the fixing frame 2 is installed on the lifting mechanism 10, which is convenient for adjusting the coaxiality. The lifting function can be used to easily adjust the height of the roller 1 so that it can be quickly aligned with the installation axis, reducing manpower consumption and the risk of falling off, and improving the safety of transportation and installation; the guide pin 4 installed at the end of the roller 1 shaft 3 can guide the roller 1 into position, ensure coaxiality, and facilitate the embedding of the positioning key, reducing knocking adjustments, greatly shortening the installation time, and effectively solving the problems of poor safety, low accuracy and low efficiency in existing installation methods.

[0036] The lifting mechanism 10 is a manual hydraulic lifting trolley or a scissor-type lifting platform. In this embodiment, it is a manual hydraulic lifting trolley.

[0037] like Figure 3 As shown, the fixing frame 2 includes a channel steel 201; mounting plates 202 are fixedly provided on both sides of the bottom surface of the channel steel 201; the mounting plates 202 are mounted on the lifting mechanism 10; two angle steels 203 are provided opposite each other at both ends of the channel steel 201; the angle steels 203 are fixedly provided on the mounting plates 202. Connecting blocks 204 are fixedly provided on the bottom surface of the mounting plates 202; the connecting blocks 204 are fixedly provided on the lifting mechanism 10. The connecting blocks 204 fixed on the bottom surface of the mounting plates 202 can form a stable transition connection between the mounting plates 202 and the lifting mechanism 10, further enhancing the reliability of the connection between the fixing frame 2 and the lifting mechanism 10 and avoiding looseness problems that may occur due to direct connection; at the same time, the specifications of the connecting blocks 204 can be flexibly adjusted according to the installation dimensions of the lifting mechanism 10, thereby improving the adaptability of the fixing frame 2 to different types of lifting mechanisms 10, making the installation of the fixing frame 2 more flexible and convenient, and providing more reliable structural support for the stable placement and precise adjustment of the roller 1. The fixing frame 2 adopts the channel steel 201 as the main body, which can stably bear the weight of the roller 1, limit the position of the roller 1 on both sides of the axis, and provide a reliable placement foundation for the roller 1; the mounting plates 202 on both sides of the bottom surface of the channel steel 201 can firmly install the fixing frame 2 on the lifting mechanism 10, ensure the firmness of the connection, and facilitate the disassembly and assembly of the fixing frame 2 and the lifting mechanism 10; the two angle steels 203 arranged opposite to each other at the two ends of the channel steel 201 are fixed on the mounting plate 202, which can limit the roller 1 from both sides to prevent the roller 1 from rolling or offset during the placement, movement and installation process, further improving the stability of the placement of the roller 1. The overall structural design is simple and practical, providing a strong guarantee for the safe placement, stable movement and efficient installation of the roller 1.

[0038] like Figure 4 and Figure 5As shown, a tapered surface 401 is provided on the outer edge of one end of the guide pin 4; a stepped hole 402 is coaxially provided on the guide pin 4; the large-diameter end of the stepped hole 402 is located at the end of the tapered surface 401 on the guide pin 4; and a plurality of key slots 403 are uniformly provided along the circumference of the outer wall of the guide pin 4. The tapered surface 401 on the outer edge of one end of the guide pin 4 guides the roller 1 to dock with the mounting shaft more smoothly, reducing the difficulty of initial alignment. The coaxial stepped hole 402 not only reduces the weight of the guide pin 4 for easier operation, but also provides space for bolt connection. The bolts in the stepped hole 402 can securely connect the guide pin 4 to the rotating shaft 3, making assembly and disassembly convenient and the connection reliable. The plurality of key slots 403 uniformly provided along the circumference of the outer wall can quickly match positioning keys at different angles, significantly reducing the adjustment time when inserting the positioning key, further improving positioning accuracy. The overall structural design effectively enhances the practicality and stability of the guide pin 4, helping to improve installation efficiency and quality.

[0039] When in use, adjust the lifting mechanism 10 to the initial low position to ensure that the fixing frame 2 is placed stably. Carefully place the roller 1 to be installed in the channel steel 201 of the fixing frame 2, and use the angle steels 203 at both ends of the channel steel 201 to limit the roller 1 to prevent it from rolling and deviating during placement.

[0040] Install the guide pin: Use bolts to firmly connect the guide pin 4 to the end of the rotating shaft 3 of the roller 1 through the stepped hole 402 of the guide pin 4, ensuring that the guide pin 4 is firmly installed and its tapered surface 401 faces the side of the roller 1, and one of the key slots 403 is positioned to match the key slot of the roller 1.

[0041] Cleaning and oiling: When the roller 1 is in a fixed state, it should be thoroughly cleaned to remove surface impurities, and then anti-rust oil should be applied to the required parts to avoid anti-rust oil contamination during manual handling and flipping.

[0042] Height adjustment: Operate the lifting mechanism 10 and use its lifting function to slowly adjust the height of the fixed frame 2. At the same time, adjust the position of the lifting mechanism 10 in the horizontal plane so that the roller 1 and the rotating shaft 3 gradually approach the same horizontal height. By observing the rough alignment, reduce the deviation in the height direction.

[0043] Alignment: The tapered surface 401 of the guide pin 4 guides the roller 1 and the shaft 3 to align, reducing the difficulty of initial alignment. During the alignment process, the positioning key is inserted into the keyway 403 of the guide pin 4 as needed to reduce adjustment time.

[0044] Complete the installation: After the roller 1 is precisely docked with the shaft 3 and the positioning key is installed in place, remove the bolts used to fix the guide pin 4, remove the guide pin 4, complete the installation of the roller 1, and finally reset the lifting mechanism 10 to the initial low position.

[0045] The fixing frame 2, formed by the channel steel 201 and angle steel 203, forms a stable bearing space that securely holds the roller 1, preventing safety hazards such as crushing and bruising caused by an unstable center of gravity during manual handling or turning. The tapered surface 401 of the guide pin 4 guides the roller 1 smoothly into contact with the mounting shaft, reducing the difficulty of initial alignment. The circumferentially distributed keyways 403 quickly match positioning keys at different angles, reducing the number of keystroke adjustments, ensuring the coaxiality of the roller 1 with the mounting shaft, and improving installation accuracy. The roller 1 is stable on the fixing frame 2, making it easy to clean and oil it directly, eliminating the risk of rust-proof oil contamination during manual turning and reducing subsequent cleaning steps. The guide pin 4 is quickly attached and detached from the rotating shaft 3 via bolts in the stepped hole 402, providing convenient operation and a reliable connection, further improving operational efficiency. The fixing frame 2 is assembled from conventional profiles such as the channel steel 201, mounting plate 202, and angle steel 203, resulting in a simple structure, low cost, and ease of fabrication and maintenance. The connecting block 204 can be flexibly adjusted according to the installation size of the lifting mechanism 10, so that the fixing frame 2 is adapted to different types of lifting equipment such as manual hydraulic lifting trolleys and scissor-type lifting platforms, and has a wide range of applications.

[0046] Example 2

[0047] like Figure 6 and Figure 7 As shown, the difference from Example 1 is that the fixed frame 2 is slidably set on the lifting mechanism 10. The workbench roller installation device also includes a translation drive mechanism; the translation drive mechanism is set on the lifting mechanism 10, and the translation drive mechanism is used to push the fixed frame 2 with the roller 1 placed thereon to translate along the axial direction of the rotating shaft 3. The mounting plate 202 is slidably set on the lifting mechanism 10, and cooperates with the translation drive mechanism set on the lifting mechanism 10 to push the fixed frame 2 with the roller 1 placed thereon to translate smoothly along the axial direction of the rotating shaft 3, and can adjust the axial distance between the roller 1 and the rotating shaft 3. There is no need to manually push the fixed frame 2 to fine-tune the position, which reduces manpower consumption; this design enables the roller 1 to further control the axial position after the height is adjusted, ensuring that the docking of the roller 1 and the rotating shaft 3 is more precise, reducing bumps and jams during the installation process, effectively improving the smoothness and accuracy of the installation, and further improving the overall installation efficiency.

[0048] like Figure 6 and Figure 8As shown, the lifting mechanism 10 is provided with a guide rail 8; a slider 9 is slidably provided on the guide rail 8; and the slider 9 is mounted on the bottom surface of the mounting plate 202. The guide rail 8 provided on the lifting mechanism 10 cooperates with the slider 9 on the bottom surface of the mounting plate 202 to provide guidance for the translation of the fixed frame 2, effectively constraining the translation trajectory of the fixed frame 2, preventing deviation or shaking during translation, and ensuring that the fixed frame 2 slides smoothly along the axis of the rotating shaft 3. This sliding cooperation method has low friction resistance, making the translation of the fixed frame 2 smoother and more labor-saving, reducing the load on the translation drive mechanism, and at the same time improving the accuracy of position adjustment, further ensuring the accuracy of the docking of the roller 1 and the rotating shaft 3, and laying a solid foundation for the efficient and precise installation of the roller 1.

[0049] The translation drive mechanism includes a base plate 5; a telescopic assembly 7 is fixedly provided on the base plate 5; a push plate 6 is connected to the output end of the telescopic assembly 7; one side of the push plate 6 can contact the two angle steels 203 and the channel steel 201. The telescopic assembly 7 is an electric push rod or an oil cylinder or an air cylinder; Figure 9 and Figure 10 As shown, a cylinder 601 is fixedly provided on one side of the push plate 6; the output end of the telescopic assembly 7 is disposed within the cylinder 601; and a number of reinforcing ribs 602 are provided between the side wall of the cylinder 601 and the push plate 6. In the translation drive mechanism, the base plate 5 provides a stable support for the entire mechanism, ensuring the stability of the telescopic assembly 7 during operation; the push plate 6 connected to the output end of the telescopic assembly 7, by contacting the two angle steels 203 and the channel steel 201, can evenly apply thrust to the fixed frame 2, so that the force on the fixed frame 2 is balanced, avoiding deformation or displacement of the fixed frame 2 due to excessive local force, and ensuring that the fixed frame 2 translates smoothly and accurately along the guide rail 8; this structural design can achieve effective drive and control of the translation of the fixed frame 2, further improve the accuracy and efficiency of the docking of the roller 1 and the rotating shaft 3, reduce the need for manual intervention, and enhance the practicality and reliability of the device. The telescopic component 7 uses an electric push rod, an oil cylinder or an air cylinder, and can flexibly select the power source according to the actual working conditions, thereby improving the adaptability and practicality of the device; the cylinder 601 fixed on one side of the push plate 6 can form a wrapping limit for the output end of the telescopic component 7, ensuring the accurate direction of thrust transmission, and avoiding the deviation of the output end of the telescopic component 7 affecting the force on the push plate 6; a number of reinforcing ribs 602 between the side wall of the cylinder 601 and the push plate 6 enhance the structural strength of the connection between the cylinder 601 and the push plate 6, preventing deformation or breakage when subjected to force, ensuring that the thrust is stably transmitted to the fixed frame 2, further improving the reliability and stability of the translation drive mechanism, and assisting the installation process of the roller 1 to proceed efficiently and smoothly.

[0050] like Figure 9 、 Figure 11 and Figure 12As shown, the workbench roller mounting device also includes a centering mechanism; the centering mechanism includes a cross slot 11 provided on the push plate 6; the cross slot 11 is provided on the side of the push plate 6 away from the cylinder 601; the centering mechanism also includes a fixing block 12; the fixing block 12 can be placed at the large diameter end within the stepped hole 402; the fixing block 12 is coaxially provided with a through hole 1201; a flashlight 13 is placed within the through hole 1201. A disk 15 is provided on one side of the fixing block 12 via a connecting rod 14; a cross hole 1501 is fixedly provided in the center of the disk 15.

[0051] In the centering mechanism, the cross groove 11 on the push plate 6 away from the side of the cylinder 601 can be used as a visual alignment reference to help the operator quickly judge the alignment status of the roller 1 and the rotating shaft 3; the fixed block 12 can be stably placed on the large diameter end in the stepped hole 402, and its coaxial through hole 1201 provides an installation space for the flashlight 13. The light emitted by the flashlight 13 can be emitted along the axial direction, and by cooperating with the cross groove 11, a clear optical alignment reference is formed, which is convenient for the operator to intuitively observe the coaxiality of the roller 1 and the rotating shaft 3, greatly reducing the centering adjustment time, and further ensuring the installation quality and efficiency. The disc 15 set on one side of the fixed block 12 through the connecting rod 14, together with the cross hole 1501 in the middle of the disc 15, can form a multi-level optical alignment reference with the cross groove 11 on the push plate 6; after the flashlight 13 light passes through the through hole 1201 of the fixed block 12, it forms a precise light beam through the cross hole 1501 of the disc 15, which corresponds to the cross groove 11 of the push plate 6, which can further reduce the alignment error and allow the operator to more clearly judge the coaxiality of the roller 1 and the rotating shaft 3; at the same time, when the fixed block 12 is placed on the large diameter end in the stepped hole 402, the cross hole 1501 is used to place it corresponding to the key groove 403 of the roller 1, which facilitates the subsequent embedding of the key bar in the key groove 403.

[0052] In this embodiment, the lifting mechanism 10 is a manual hydraulic lifting trolley.

[0053] When in use, preliminary preparations are as follows: adjust the lifting mechanism 10 to the initial height, ensure that the fixing frame 2 is in a low position, and place the roller 1 to be installed stably on the channel steel 201 of the fixing frame 2, so that the roller 1 is limited on both sides by the angle steel 203 to prevent rolling.

[0054] Install the guide pin: Use the bolt in the stepped hole 402 of the guide pin 4 to firmly connect the guide pin 4 to the end of the rotating shaft 3 of the roller 1, and ensure that one of the key slots 403 of the guide pin 4 corresponds to the key slot position of the rotating shaft 3.

[0055] Centering mechanism deployment: Place the fixed block 12 at the large-diameter end of the stepped hole 402 of the guide pin 4. Install the flashlight 13 in the through-hole 1201 of the fixed block 12. Turn on the flashlight 13 to emit a beam of light through the cross-shaped through-hole 1501 in the center of the disk 15. Adjust the position of the fixed block 12 so that the cross-shaped beam of light emitted through the cross-shaped through-hole 1501 aligns with the keyway of the rotating shaft 3. In other words, one branch of the cross-shaped beam of light aligns with the center of the keyway of the rotating shaft 3.

[0056] Height Adjustment: Operate the lifting mechanism 10 to adjust the height of the fixed frame 2 using its lifting function, so that the roller 1 on the fixed frame 2 and the rotating shaft 3 are approximately at the same level, initially reducing the height difference. Simultaneously, move the lifting mechanism 10 to adjust the position of the roller 1 on the fixed frame 2 within the horizontal plane, initially reducing the distance within the horizontal plane.

[0057] Precise alignment: Use the flashlight 13 to pass through the cross hole 1501 of the disc 15 to form a cross-shaped beam that matches the cross slot 11 on the push plate 6. The operator determines the coaxiality based on the optical alignment reference and fine-tunes the height and horizontal position of the lifting mechanism 10 until the roller 1 and the rotating shaft 3 are aligned.

[0058] Translation alignment: Start the translation drive mechanism, the telescopic component 7 pushes the push plate 6, and the push plate 6 contacts the angle steel 203 and the channel steel 201, so that the fixed frame 2 can be smoothly translated along the guide rail 8 on the lifting mechanism 10 through the slider 9 on the bottom surface of the mounting plate 202, and the distance between the roller 1 and the rotating shaft 3 is adjusted.

[0059] Complete the installation: Under the guidance of the conical surface 401 of the guide pin 4, make the roller 1 and the rotating shaft 3 dock smoothly, insert the positioning key into the key slot 403, and further insert it into the key slots on the roller 1 and the rotating shaft 3 to complete the connection between the roller 1 and the rotating shaft 3. Then close the translation drive mechanism, remove the centering mechanism components, and operate the lifting mechanism 10 to reset.

[0060] The fixed frame 2 stably supports the roller 1 through the channel steel 201 and angle steel 203, avoiding the risk of crushing during manual handling and flipping. The lifting mechanism 10 and the translation drive mechanism replace manual position adjustment, reducing the frequency of human contact with heavy objects and reducing the risk of falling and bumping. The tapered surface 401 and keyway 403 of the guide pin 4 ensure the coaxiality of the roller 1 with the installation axis, reducing the need for tapping adjustments. The centering mechanism forms a multi-level centering reference through the optical coordination of the cross slot 11, flashlight 13, and disk 15, minimizing alignment errors and ensuring smooth installation. The lifting mechanism 10 quickly adjusts the height, and the translation drive mechanism achieves smooth translation through the guide rail 8 and slider 9, eliminating the need for manual fine-tuning and reducing labor consumption. The quick matching of the keyway 403 and the positioning key, as well as the intuitive judgment of optical alignment, significantly shorten the centering adjustment time and improve overall installation efficiency. The cylinder 601 and reinforcing rib 602 of the push plate 6 ensure stable thrust transmission, reducing the load on the telescopic assembly 7 and extending the service life of the device.

[0061] By combining mechanical adjustment with optical alignment, the problems of poor safety, low precision and low efficiency in traditional installation methods are effectively solved, providing a stable, efficient and reliable solution for the installation of the roller 1.
