[0002] A needle roller bearing is a roller bearing with cylindrical rollers. The rollers are thin and long relative to their diameter. Such rollers are called needle rollers. Despite having a small cross-section, the bearing still has a high load-bearing capacity. The needle roller bearing is equipped with thin and long rollers, so it has a compact radial structure. When its inner diameter size and load capacity are the same as those of other types of bearings, its outer diameter is the smallest, and it is particularly suitable for support structures where the radial installation size is restricted.

[0003] When the existing assembly workshop performs the assembly operation of needle roller gaskets and needle rollers, the operator needs to manually press the needle rollers into the gaskets one by one. Each person can install at most 1000 pieces per day. Moreover, after a large number of manual assemblies, it will cause finger pain, and the installation staff needs to rotate. This not only has a large labor intensity but also has low production efficiency. Therefore, it is necessary to design a device or apparatus for the assembly workshop to complete the automatic feeding and assembly of needle rollers and solve the problems existing in the prior art.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 、For this kind of automatic assembling machine for needle roller gaskets, by setting a vibrating feeding tray with a three-channel structure, the needle rollers can be conveyed to the three feeding bottom boxes of the assembling mechanism through three feeding guide pipes. By setting a positioning template and a movable bottom plate, the needle roller gaskets can be limited by the gasket limiting grooves on the surface of the positioning template, and then the three feeding push blocks on the surface of the movable bottom plate driven by the telescopic cylinder are used to push three needle rollers upwards into the needle roller gaskets in the gasket limiting grooves, realizing the automatic assembly between the needle rollers and the needle roller gaskets, reducing the working intensity of the operators, and being beneficial to improving the working efficiency of the needle roller assembly.

[0020] , In this kind of automatic assembling machine for needle roller gaskets, a lubrication component is arranged at the bottom of the positioning template. During the upward movement of the movable bottom plate, the piston push rod on its surface is driven to move upward inside the piston air cylinder, and the air in the piston air cylinder can be input into the oil liquid box. Then, the lubricating oil liquid in the oil liquid box is input into the atomizing nozzle in the feeding bottom box through the oil liquid conduit by using air pressure. Thus, the atomizing nozzle sprays the lubricating liquid on the needle rollers, making the needle rollers move more smoothly when entering the needle roller assembly holes and making it easier for the needle rollers to enter the installation slots on the surface of the needle roller gasket, achieving the role of auxiliary assembly.
