Description

Technical Field

[0001] The utility model relates to the technical field of needle roller bearings, in particular to a positioning device for processing needle roller bearing rings. Background Technique

[0002] The needle roller bearing ring is an important part of the needle roller bearing. The needle roller bearing ring usually includes an inner ring and an outer ring, which are the main parts of the bearing. According to different bearing types and application requirements, the design of the ring will also be different. For example, the self-aligning outer ring has a spherical outer surface to adapt to the permanent angular displacement between the axis of the shaft and the axis of the bearing housing; the intermediate ring is a bearing ring with double raceways, such as the intermediate integral rib of the double raceway tapered inner ring. The working principle of the needle roller bearing is to use the rolling elements (needle rollers) to roll between the inner and outer rings, thereby reducing friction and resistance. When the bearing is subjected to axial or radial loads, the needle rollers will roll between the inner and outer rings, enabling the bearing to withstand larger loads and speeds.

[0003] When processing the needle roller bearing ring, it is necessary to ensure the stability during processing. However, considering that it is not convenient to integrally fix multiple rings in the traditional method, which greatly reduces the processing convenience and efficiency, and is extremely inconvenient. Therefore, a positioning device for processing needle roller bearing rings is urgently needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a positioning device for processing needle roller bearing rings, which solves the problem that it is not convenient to integrally fix multiple rings in the prior art, thus greatly reducing the processing convenience and processing efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A positioning device for processing needle roller bearing rings includes a frame body. A top plate is fixedly connected to the top of the frame body, and a cylinder is fixedly connected to the top of the top plate through bolts. The upper part inside the frame body is provided with a bearing plate, and the output shaft end of the cylinder penetrates through the top plate and is fixedly connected between the top of the bearing plate. The bottom of the bearing plate is slidably connected with a support plate, and a bottom plate is fixedly connected to the bottom of the frame body. Moreover, a plurality of bottom grooves are opened on the top of the bottom plate, and a plurality of bearing grooves are opened on the support plate.

[0007] Preferably, cross-shaped sliders are fixedly connected to both sides of the top of the support plate, and both cross-shaped sliders are slidably connected with the bottom of the bearing plate through cross-shaped chutes.

[0008] Preferably, there is a clearance fit between both cross-shaped sliders and both cross-shaped chutes respectively.

[0009] Preferably, insertion rods are provided on both sides of the frame body, and slots for cooperating with the insertion rods are provided on both sides of the frame body and both sides of the support plate.

[0010] Preferably, the connection between the output shaft of the air cylinder and the top plate is a sliding connection.

[0011] Preferably, all the bearing grooves and all the bottom grooves are distributed in one-to-one correspondence.

[0012] The utility model at least has the following beneficial effects:

[0013] When the positioning device for processing the needle roller bearing race is used in the utility model, first, the needle roller bearing races to be processed are placed in the bottom grooves one by one, and then the corresponding support plates slide into the bottom of the bearing plate. The bottom grooves and the bearing grooves need to correspond. Then, the air cylinder is started to drive the bearing plate and the support plate to move downward to fix the needle roller bearing race. At this time, the upper part of the needle roller bearing race is located inside the bearing groove, and the needle roller bearing race is limited by the bottom groove and the bearing groove. Compared with the prior art in which it is not convenient to fix multiple races as a whole, which greatly reduces the processing convenience and the processing efficiency, the method proposed in the utility model fixes the needle roller bearing race by the downward movement of the support plate and limits the needle roller bearing race by the bottom groove and the bearing groove, thereby strengthening the stability during the processing of the needle roller bearing race.
