All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] The following is combined Figure 1-4 The present invention describes a cylindrical pin installation tool, comprising a base plate 1, an adjustment assembly on the base plate 1, a limiting assembly on the adjustment assembly, and a fixing assembly on the adjustment assembly. The adjustment assembly includes a fixing frame 2, which is mounted on the base plate 1. A movable frame 3 is movably mounted on the fixing frame 2. A fixing seat 7 is provided inside the fixing frame 2. A threaded rod 8 is movably mounted on the fixing seat 7 and is movably connected to the movable frame 3. A driving assembly is provided on the fixing frame 2. When the height of the movable frame 3 needs to be adjusted, the threaded rod 8 rotates on the fixing seat 7, and the movable frame 3 moves on the fixing frame 2 under the action of the threaded rod 8.

[0024] Advantageously, the fixing frame 2 is provided with reinforcing ribs, which increases the stability of the fixing frame 2.

[0025] Advantageously, the drive assembly includes a rotating shaft 4 and a first bevel gear 18. The first bevel gear 18 is mounted on the threaded rod 8. The rotating shaft 4 is movably mounted on the fixed frame 2. A second bevel gear 5 is provided on the rotating shaft 4 and meshes with the first bevel gear 18. A rotating plate 6 is provided at the end of the rotating shaft 4 away from the second bevel gear 5. Rotating the rotating plate 6 can drive the rotating shaft 4 to rotate. The second bevel gear 5 follows the rotation of the rotating shaft 4 and can drive the first bevel gear 18 to rotate.

[0026] Advantageously, the base plate 1 is provided with pads, which can make the base plate 1 more stable.

[0027] Advantageously, the limiting assembly includes a fixed box 12 and a locking hole 17. The fixed box 12 is mounted on the rotating plate 6. A sliding plate 13 is provided inside the fixed box 12. A moving rod 14 is provided on the sliding plate 13, and the end of the moving rod 14 away from the sliding plate 13 passes through the side wall of the fixed box 12. A spring 15 is provided on the sliding plate 13 and the spring 15 is connected to the fixed box 12. A limiting rod 16 is provided on the sliding plate 13, and the end of the limiting rod 16 away from the sliding plate 13 passes through the side wall of the fixed box 12. The locking hole 17 is located on the rotating plate 6. When it is necessary to restrict the position of the movable frame 3 on the fixed frame 2, the movable rod 14 is pulled. The movable rod 14 drives the sliding plate 13 to move away from the rotating plate 6. The limiting rod 16 follows the sliding plate 13 away from the locking hole 17. At this time, the spring 15 is compressed, and the working box rotates with the rotating plate 6. It stops when it reaches the predetermined position. The movable rod 14 is released, the spring 15 returns to its original position, and the sliding plate 13 moves towards the rotating plate 6 under the action of the spring 15. The limiting rod 16 moves with the sliding plate 13 and enters the locking hole 17 on the fixed frame 2, thereby preventing the rotating plate 6 from rotating and thus fixing the rotating plate 6.

[0028] Advantageously, a pull block is provided at the end of the moving rod 14 away from the sliding plate 13, which facilitates the movement of the moving rod 14.

[0029] Advantageously, the fixing component includes a guide block 9, which is movably mounted on the movable frame 3. The guide block 9 is provided with a limiting block 10 and a placement groove 11. The guide block 9 can move up and down on the movable frame 3, and the placement groove 11 facilitates the placement of cylindrical pins.

[0030] Advantageously, the diameter of the limiting block 10 is larger than the diameter of the guide block 9, and the limiting block 10 prevents the guide block 9 from falling off the movable frame 3.

[0031] Working principle of this utility model:

[0032] First, place the workpiece on the base plate 1. Adjust the position of the guide block 9 according to the length of the cylindrical pin. Rotate the rotating plate 6, which drives the rotating shaft 4 to rotate. The second bevel gear 5 follows the rotating shaft 4 and drives the first bevel gear 18 to rotate. The threaded rod 8 follows the first bevel gear 18 and rotates on the fixed seat 7. The moving frame 3 moves on the fixed frame 2 under the action of the threaded rod 8, thereby adjusting the height of the moving frame 3. When it is necessary to restrict the position of the moving frame 3, pull the moving rod 14. The moving rod 14 drives the sliding plate 13 to move away from the rotating plate 6. The limiting rod 16 follows the sliding plate 13 away from the locking hole 17. At this time, the spring 15 is compressed. The work box rotates with the rotating plate 6 and stops at the predetermined position. The moving rod 14 is released, the spring 15 returns to its original position, and the sliding plate 13 moves towards the rotating plate 6 under the action of the spring 15. The limiting rod 16 moves with the sliding plate 13 and enters the locking hole 17 on the fixing frame 2, thereby preventing the rotating plate 6 from rotating and fixing the rotating plate 6. One end of the cylindrical pin is placed into the guide block 9, and the end of the cylindrical pin away from the guide block 9 abuts against the place where the workpiece needs to be installed. At this time, the cylindrical pin makes the limiting block 10 away from the moving frame 3. Then, the limiting block 10 is tapped with a tool, and the limiting block 10 can drive the cylindrical pin on the guide block 9 to move, so that the installation process of the cylindrical pin is stable.
