Description

Technical Field

[0001] The invention relates to the technical field of sliding bearing assembly, in particular to an assembly device that can be used for sliding bearings. Background Art

[0002] Sliding bearing is a bearing that works under sliding friction. Sliding bearings work smoothly, reliably and without noise. Under liquid lubrication conditions, the sliding surfaces are separated by lubricating oil without direct contact, which can also greatly reduce friction loss and surface wear. The oil film also has a certain vibration absorption ability, but the starting friction resistance is large. The part of the shaft supported by the bearing is called the journal, and the part that matches the journal is called the bearing shell. The friction-reducing material layer cast on the inner surface of the bearing shell to improve the friction properties of the bearing shell surface is called the bearing liner. The materials of the bearing shell and the bearing liner are collectively referred to as sliding bearing materials. Sliding bearings are generally used under high-speed and light-load conditions. When assembling sliding bearings, it is necessary to prevent dirt from entering between the bearings. The general lifting fixture may wear off the paint on the surface of the bearing cover when lifting the bearing cover due to the hard chuck, causing it to fall into the bearing. Therefore, a device is needed to avoid severe friction on the bearing cover when lifting it. Summary of the invention

[0012] The present invention provides an assembly device that can be used for sliding bearings. It has the following beneficial effects: (1) When the assembly equipment for sliding bearings is used, the motor is started to drive the threaded rod to move the guide rod, so that the clamping plate is opened and closed, and the clamping mechanism can clamp the bearing cover. As the clamping plate contacts the surface of the bearing cover, the push rod is retracted toward the inside of the fixed frame, so that the push plate squeezes the air inside the air cavity and the air is ejected through the connecting pipe, and the lower side of the clamping part of the surface of the bearing cover is blown to prevent dirt adhering to the surface of the bearing cover from falling into the inside of the bearing during assembly.

[0013] (2) The assembly equipment for sliding bearings can be used to suck air from the right side of the air cavity through the air inlet pipe when the push plate moves, so that the moving block slides into the cavity and the clamping plate sucks air, thereby achieving the purpose of sucking dirt at the clamping position into the interior of the connecting leather and preventing dirt at the clamping position from falling into the interior of the bearing when the dirt is clamped to the upper side of the bearing and released.

[0014] (3) The assembly equipment for sliding bearings can make the dispersion block extend out of the connecting pipe when the connecting pipe is spraying air, and the airflow can make the dispersion block rotate. The airflow is dispersed through the guide groove on the dispersion block, so as to increase the blowing area of ​​the airflow and the cleaning area.

[0015] (4) When the assembly equipment for sliding bearings is hoisted to the target position and the bearing cover is lowered, the pressure of the clamping plate disappears and the first spring rebounds. However, since the air intake pipe extends out of the air cavity, the exhaust speed of the air intake pipe is slowed down, and the recovery speed of the moving block is also slowed down, causing the sealing plate to open later. After leaving the hoisting position, the sealing plate can be slowly opened to discharge dirt to avoid contaminating the bearing. BRIEF DESCRIPTION OF THE DRAWINGS

It passes through the fixed frame 701 and extends to the interior of the cavity. The right outer wall of the air inlet pipe 708 is connected to the upper side of the inner wall of the cavity through the spring piece 709. Air holes are opened on the left and middle of the air inlet pipe 708. The left side of the movable block 710 is inserted into the fixed frame 701 and passes through the fixed frame 701 to extend to the interior of the cavity. The sewage discharge mechanism 712 is arranged inside the connecting leather 702 at a position on the left side of the clamping plate 703. A sewage discharge port is opened on the lower side of the connecting leather 702, and the sewage discharge mechanism 712 is arranged inside the sewage discharge port.

[0022] The dispersion mechanism 711 includes a bracket 101, a moving rod 102, a second spring 103, and a dispersion block 104.

[0024] When in use, the machine body is fixed on an external mobile device, and when it moves to the position of the bearing cover, the motor 3 is started to rotate the output rod of the motor 3. Since the threaded rod 4 is restricted by the guide rod 5, the threaded rod 4 will rotate on the output rod of the motor 3, so that the threaded rod 4 drives the guide rod 5 to descend, and the guide rod 5 slides and descends inside the slide rail 6, and the traction clamping plate 2 is closed, so that the clamping plate 703 contacts the surface of the bearing cover.

When the exhausted gas passes through the dispersion mechanism 711, the pressure of the airflow causes the dispersion block 104 to extend out of the connecting pipe 707. At the same time, the second spring 103 is deformed, and the airflow blows the dispersion block 104 to rotate. Due to the existence of the guide groove, the gas is dispersed to the surroundings. At the same time, due to the upward movement of the push plate 705, the lower side of the push plate 705 is inhaled through the air intake pipe 708, which causes the air intake pipe 708 to extend into the interior of the air cavity, and at the same time, the shrapnel 709 is deformed. The subsequent inhalation of air in the air cavity reduces the air pressure inside the cavity, causing the moving block 710 to move toward the interior of the cavity. 703, and the first spring 706 rebounds to reset the push plate 705. The upper side of 705 is refilled with gas, and since the air inlet pipe 708 is reset due to the elastic force of the shrapnel 709, the exhaust on the lower side of the push plate 705 can only be exhausted through the small hole on the left side of the air inlet pipe 708, making the exhaust speed slower, then the recovery speed of the push rod 704 is slowed down, and the reset speed of the moving block 710 is slowed down, so that the clamping plate 703 is directly separated from the bearing cover, and it will not be rubbed to cause debris to fall, and the sealing plate 202 will also be delayed due to the slow reset speed of the moving block 710. Although the clamping plate 703 is not blocked, it is delayed to open due to the lack of airflow impact to prevent dirt from falling on the bearing.
