[0021] The utility model will be further described through examples in combination with the drawings.
[0022] Referring to the drawings Figures 1-4 An assembly tool for roller built-in bearing, containing rotating disc 1, lead screw 2, assembly frame 3 and pushing disc 4, the assembly frame 3 contains front baffle 31, rear baffle 32 and support 33, and the front baffle 31 and the rear baffle 32 are connected together through the support 33, the lead screw 2 is screw-connected on the front baffle 31, one end of the lead screw 2 is fixedly connected together with the rotating disc 1, the other end of the lead screw 2 is rotatably connected together with the pushing disc 4, and the pushing disc 4 is located between the front baffle 31 and the rear baffle 32.
[0023] In the embodiment, referring to the drawings Figure 1 , 2The tool comprises a rotating disc 1, a screw rod 2, an assembling frame 3, and a pushing disc 4. The rotating disc 1 is installed at one end of the screw rod 2, and the screw rod 2 is fixed with the rotating disc 1 at the center. The screw rod 2 is perpendicular to the plane of the rotating disc 1, and rotates with the rotating disc 1. The other end of the screw rod 2 is processed with a disc-shaped boss. In use, the boss contacts with the pushing disc 4 to provide enough pushing force for the pushing disc 4. The end of the screw rod 2 passes through the hole in the center of the pushing disc 4 to connect the pushing disc 4. The end of the screw rod 2 connected with the pushing disc 4 is a small-diameter cylinder without screw thread. The cylinder is used to install the pushing disc 4. The diameter of the cylinder is smaller than the hole in the center of the pushing disc 4, and the pushing disc 4 can rotate freely around the cylinder. The pushing disc 4 is circular, and has four perspective holes 7. The outer surface of the pushing disc 4 is provided with a rubber layer. The pushing disc 4 and the rotating disc 1 are arranged on both sides of the front baffle 31 respectively, and are parallel to the plane of the front baffle 31.
[0024] Referring to the drawings Figure 1 The assembling frame 3 is composed of a front baffle 31, a rear baffle 32, and a support 33. The front baffle 31 and the rear baffle 32 are arranged in parallel, and are connected and fixed together by the support 33. The front baffle 31 is provided with a threaded hole in the center, and the screw rod 2 passes through the hole in the center of the front baffle 31 and is screwed with the hole. The front baffle 31 is circular, and also has four perspective holes 7. The rear baffle 32 is circular ring-shaped, and the plane is supported by three pieces. The support 33 is three long strip steel plates with arc in the width direction, and are evenly distributed to form a semi-cylindrical shape.
[0025] Referring to the drawings Figure 3 、 4 In use, the tool is placed on the horizontally placed roller 6, and the support 33 in the assembling frame 3 is placed on the upper surface of the roller body to wrap the upper half of the roller body. Then the assembling frame 3 is translated to make the rear baffle 32 close to the end surface of the roller 6, and the rotating disc 1 is counterclockwise rotated to make the screw rod 2 retract to drive the pushing disc 4 to retract, so that there is enough space between the pushing disc 4 and the roller 6 to put the bearing 5 into the hole of the roller 6. Then the bearing 5 is put into the hole of the roller 6, and then the rotating disc 1 is clockwise rotated to make the pushing disc 4 close to the end surface of the bearing 5. At this time, the position of the bearing 5 is checked through the perspective holes 7 on the pushing disc 4. After confirming that the position is correct, the rotating disc 1 is continuously clockwise rotated, the screw rod 2 gradually extends to drive the pushing disc 4 to move towards the roller 6, and the bearing 5 is slowly pushed into the roller 6. In this process, the assembling frame 3 bears a large force, the front baffle 31 is subjected to the force of the screw rod 2 pushing outwards, and the force is reacted to the pushing disc 4 to push the bearing 5 to move, the bearing 5 pushes the roller 6 to move in the other direction, the rear baffle 32 is clamped at the other end of the roller 6 to provide a counterforce to the roller 6. Under the interaction of various parts, the bearing 5 is slowly pushed into the roller 6 to be assembled in place. After the bearing 5 is in place, the rotating disc 1 is counterclockwise rotated to retract the screw rod 2 and the pushing disc 4 from the roller 6, and the position of the bearing 5 is checked. After confirming that the position is correct, the tool is removed, and the bearing 5 is assembled. In the whole assembling process, the bearing 5 is not subjected to any external force impact and part wear, and is perfectly protected.
