Description

Technical Field

[0001] The utility model relates to the technical field of fixture equipment, in particular to a fixing fixture for machining needle roller bearings. Background Art

[0002] Needle roller bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. This type of roller is called a needle roller. Despite its small cross-section, the bearing still has a high load-bearing capacity. Needle roller bearings are equipped with thin and long rollers, so the radial structure is compact. When its inner diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest, which is particularly suitable for support structures with restricted radial installation dimensions. In the process of needle roller bearing production and processing, it is usually necessary to add cylindrical rollers and other components inside, but needle roller bearings are prone to slipping during the installation process, causing them to shift in position, making it difficult to install cylindrical rollers and other steps, thereby affecting their processing efficiency. Therefore, it is necessary to design a fixing fixture for needle roller bearing processing to solve this problem.

[0003] The application number is CN202221132598.6, which discloses a fixing fixture for processing needle roller bearings, including a housing, observation windows are fixedly installed on both sides of the housing, and a first rotating motor is fixedly installed at one end of the housing, the output shaft of the first rotating motor is connected to a first screw through the housing, and one end of the first screw is rotatably connected to the housing, the outer side of the first screw is connected to a moving block through a thread, and a flip rod is rotatably connected inside the moving block, one end of the flip rod is rotatably connected to a fixed frame, a second screw is rotatably connected inside the housing, the outer side of the second screw is connected to a second rotating motor through a thread, and the output shaft of the second rotating motor is connected to a positioning column. The utility model can not only play a good fixing effect, but also facilitate the processing of the inner and outer sides of the bearing, and is practical.

[0004] The fixing fixture for processing needle roller bearings disclosed in the above document has the following defects: after the fixture clamps the bearing, the bearing needs to be processed by a processing component. When the bearing fixed by the fixture needs to be flipped in cooperation with the processing component, this structure cannot be realized.

[0005] It can be seen from this that the existing fixing fixture does not have the function of flipping and adjusting the bearing matching processing assembly, and it is necessary to improve the existing deficiencies and provide a function that can flip and adjust the bearing matching processing assembly.
