Description

Technical Field

[0001] The utility model relates to the technical field of needle roller bearings, in particular to an annular cutting device for processing needle roller bearings. Background Art

[0002] Needle roller bearings are roller bearings with high aspect ratio rollers. The rollers are thin and long, and are called needle rollers. Despite their small cross-section, needle roller bearings still have a high load bearing capacity. Needle roller bearings are equipped with thin and long rollers, so the radial structure is compact. When the inner diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest. They are particularly suitable for support structures with limited radial mounting dimensions. Needle roller bearings can be selected without inner rings or needle roller and cage assemblies according to different applications. The journal surface and the housing hole surface that matches the bearing are directly used as the inner and outer rolling surfaces of the bearing. In order to ensure that the load capacity and running performance are the same as those of bearings with rings, the hardness, machining accuracy and surface quality of the shaft or seat raceway surface should be combined with the bearing rings and the purpose.

[0003] In the process of processing needle roller bearings, circular cutting is required. Since the efficiency of the circular cutting needs to be ensured, we consider that when performing the circular cutting of the needle roller bearing material, only the circular cutting tool rotates, thereby failing to ensure the processing efficiency of the material. At the same time, there may be a situation where the processing is not in place, which is extremely inconvenient. Therefore, an circular cutting device for needle roller bearing processing is urgently needed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide an annular cutting device for processing needle roller bearings, which solves the problem that in the prior art, when performing annular cutting of needle roller bearing materials, only the annular cutting tool rotates, thereby failing to ensure the processing efficiency of the material and there is also the problem that the processing is not in place.

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

[0006] A circular cutting device for needle roller bearing processing comprises a frame, a bearing plate is slidably connected to the inner side of the frame, and the bottom of the bearing plate is fixedly connected to a first motor by bolts, and a circular cutting knife is provided at the bottom of the bearing plate, wherein the top of the circular cutting knife is drivingly connected to the output shaft of the first motor, the bottom of the frame is fixedly connected to a second motor by bolts, and the inner lower part of the frame is rotatably connected to a rotating rod, the top end of the rotating rod is fixedly connected to an electromagnetic suction plate, and the bottom end of the rotating rod passes through the bottom of the frame and is drivingly connected to the output shaft of the second motor.

[0007] Preferably, the top of the frame is fixedly connected to a top plate, and the top of the top plate is fixedly connected to a cylinder via bolts, and an output shaft of the cylinder passes through the top plate and is fixedly connected to the top of the bearing plate.

[0008] Preferably, a protective plate is provided on one side of the frame, and both sides of the protective plate are fixedly connected to one side of the frame through threaded rods.

[0009] Preferably, a sliding block is fixedly connected to one side of the supporting plate, and the sliding block is slidably connected to the inner wall of the frame through a sliding rail.

[0010] Preferably, the bottom end of the rotating rod passes through the bottom of the frame through the bearing sleeve.

[0011] Preferably, the connection between the cylinder and the top plate is a sliding connection.

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

[0013] When the utility model is used for a circular cutting device for processing needle bearings, first, a bearing material plate that needs to be circularly cut is placed on an electromagnetic suction plate, fixed by electromagnetic suction, and the supporting plate is moved downward at the same time. At the same time, the first motor is started to drive the circular cutter to rotate, and the material is circularly cut during the downward movement. At the same time, the second motor is started to drive the material plate on the electromagnetic suction plate to rotate, and the rotation direction is opposite to that of the circular cutter, which can greatly enhance the circular cutting efficiency of the material plate. Compared with the prior art, when performing circular cutting of needle bearing materials, only the circular cutting tool rotates, thereby failing to ensure the processing efficiency of the material, and there is also the problem of in-place processing. The method proposed in the utility model fixes the material by the electromagnetic suction plate, and at the same time, the material plate on the electromagnetic suction plate rotates in the opposite direction to the circular cutter, which can greatly improve the cutting efficiency of the circular cutter and has high practicality.
