A magnetic plate is installed at one end of the telescopic rod, and a guide plate is fixedly mounted on the lower half of the fixed column. The device features several through slots, and a movable column is fixedly installed at the bottom of the telescopic rod, allowing the movable column to slide within the through slots of the guide plate. This provides guidance and further improves the accuracy of the telescopic direction. A fastening plate is fixedly installed at the bottom of the fixed column and the guide plate to effectively prevent parts on the outer wall of the fixed column from falling off, significantly improving installation efficiency and automation. This directly reduces manual intervention, and the installation device offers operational flexibility, is suitable for cylindrical roller bearings of different specifications, improves installation accuracy and stability, ensures safety and reliability for components, greatly reduces operational risks, and protects the surface of the cylindrical rollers from damage.

It can install cylindrical roller bearings of different specifications. Several through holes are formed at the bottom of the slots in the toothed plate to position the gears. When the appropriate installation size is achieved, the locating pins can be inserted into the through holes of the toothed plate to achieve the positioning effect. Two rollers are movably connected within the slots in the gears, allowing the rollers to be fixed to the bottom of the fixing block via a fixing rod, achieving both fixation and displacement. A measuring rod is fixedly installed at the bottom of the toothed plate, and its bottom contacts the outer wall of the bearing to determine the installation dimensions. This significantly improves the adaptability to different bearing specifications, effectively ensuring the stability of installation accuracy. Structurally, it ensures the accuracy of installation dimensions and reduces installation quality problems caused by positional deviations. Attached Figure Description

Detailed Implementation
[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0021] like Figure 1-5As shown, this utility model provides a technical solution: an installation device for cylindrical roller bearings, including a base 1, a crossbeam 2 fixedly installed on the top of the base 1, a positioning block 8 fixedly installed on the top of the base 1, a handle 7 rotatably connected in a through hole in the positioning block 8, a threaded rod 10 fixedly connected to the protruding part at the bottom of the handle 7, a connecting rod 11 threadedly connected to the outer wall of the threaded rod 10, the through hole inside the positioning block 8 provides a fulcrum for the handle 7 to rotate stably around the through hole, and the handle 7 rotates together with the threaded rod 10; a movable clamping plate 12 is fixedly installed on the side of the connecting rod 11 away from the threaded rod 10, and a fixed clamping plate 9 is fixedly installed on the top of the base 1, the connecting rod 11 threadedly connected to the threaded rod 10 moves linearly along the direction of the thread, thereby driving the movable clamping plate 12, so that the movable clamping plate 12 cooperates with the fixed clamping plate 9 to position the bearing, and the thread has self-locking properties, which can ensure the stability after clamping the bearing and prevent loosening.
[0022] An electric push rod 3 is fixedly installed at the bottom of the protruding part of the crossbeam 2. A fixing block 4 is fixedly installed at the bottom of the electric push rod 3. An installation mechanism 5 is fixedly installed at the bottom of the fixing block 4. The installation mechanism 5 includes a fixing column 501 and a measuring mechanism 6 inside the installation mechanism 5. The measuring mechanism 6 includes a toothed plate 601. Two rollers 602 are movably connected in a through groove in the toothed plate 601. Fixing rods 603 are fixedly installed on the top of the two rollers 602 respectively. A measuring rod 604 is fixedly installed at the bottom of the toothed plate 601. The toothed structure on the outer wall of the toothed plate 601 can be used to cooperate with the gear 502 to achieve precise transmission. The through groove allows the rollers 602 to be limited. The direction of movement is controlled to ensure that the measuring mechanism 6 moves stably along the preset path. The fixed rod 603 can provide a support point for the roller 602. At the same time, through the cooperation between the roller 602 and the toothed plate 601, the movement range or trajectory of the toothed plate 601 is limited, and the fixing force of the mounting mechanism 5 is transmitted. The measuring rod 604 can realize the measurement function through the synchronous movement of the toothed plate 601. Several through holes are opened at the bottom of the inner wall of the toothed plate 601. A positioning pin 605 is inserted into one of the through holes, and the top end of the positioning pin 605 passes through the fixing block 4. The through hole can be fixed by the positioning pin 605 through the through hole of the fixing block 4, thereby limiting the displacement of the toothed plate 601.
[0023] A gear 502 is rotatably connected to the outer wall of the fixed column 501. Several guide blocks 506 are fixedly installed on the outer wall of the fixed column 501. Telescopic rods 507 are movably connected to the through slots opened in the guide blocks 506. A through slot is opened on the top of the guide blocks 506. Displacement rods 503 are fixedly connected to the top of the telescopic rods 507. Sleeves 504 are fixedly installed on the outer wall of the displacement rods 503. A common movable tube 505 is fixedly installed between the outer walls of two sleeves 504. A magnetic suction plate 508 is fixedly installed at the end of the telescopic rod 507 away from the fixed column 501. The bottom of the magnetic suction plate 508 is provided with a circular roller magnetic suction groove. Several roller magnetic suction grooves are distributed at equal angles. The magnetic suction plate 508 can attract cylindrical rollers and install them into the cage, which is convenient to operate. The design of the magnetic suction groove can serve as a positioning reference to ensure the positioning accuracy of the workpiece in the adsorption state and prevent displacement. The bottom of the telescopic rod 507 is fixedly installed with a moving column 509. The outer wall of the fixed column 501 is fixedly installed with a guide plate 510. Several through grooves are opened inside the guide plate 510. The bottom of the fixed column 501 is fixedly installed with a fastening plate 511.
[0024] The working principle of this utility model is as follows: The bearing to be installed is placed inside the fixed clamping plate 9. Then, the handle 7 is rotated to fix the bearing in place by the movable clamping plate 12. The cylindrical rollers are then individually attracted into the bottom through-hole of the magnetic suction plate 508. The workpiece's installation dimensions are then measured. The measuring rod 604 within the measuring mechanism 6 is displaced, causing the toothed plate 601 to slide. While the toothed plate 601 moves horizontally, the roller 602 rotates within the through-groove of the toothed plate 601. The gear 502 meshing on one side of the toothed plate 601 rotates. The gear 502, through its internal arc-shaped through-groove, allows five displacement rods 503 to move within the arc-shaped groove, causing the bottom telescopic rod 507 to move synchronously. The telescopic rod 507 then slides and extends within the guide block 506. The five displacement rods... 503 is connected to a displacement rod 503 in each group and slides synchronously through the movable tube 505. The movable tube 505 can also extend and retract while moving. The moving column 509 at the bottom of the telescopic rod 507 slides through the through groove opened in the guide plate 510 and rotates synchronously. When the measuring rod 604 moves to the inner wall of the bearing, the positioning pin 605 is inserted from the fixed block 4 into the through hole opened in the toothed plate 601. Then the measuring rod 604 is retracted. At this time, the electric push rod 3 pushes the fixed block 4 and moves downward, so that the installation mechanism 5 installs the cylindrical roller bearing in the cage. At this time, the installation of the cylindrical roller is completed. The electric push rod 3 is raised to the original position, the handle 7 is turned, and the clamping plate 12 is moved backward to install the inner ring of the bearing into the shaft bearing. At this time, the installation is completed.
