Description

Technical field

[0001] The utility model belongs to the technical field of bearing drilling, especially a bearing drilling device. Background technique

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The outer ring of the bearing is an important part of the bearing. The outer ring of the bearing plays a role in supporting and orienting in the bearing. It is responsible for bearing all the loads transmitted to the shaft in the machine device, including radial loads and axial loads.

[0003] During the processing of the outer ring of the bearing, it needs to be drilled. The purpose is to use it as an oil hole for lubrication to extend the service life of the bearing. However, in the existing technology, most drilling methods are that workers use a drilling device to drill the outer ring of the bearing. This drilling method requires workers to be highly concentrated, so as to avoid the situation of incorrect drilling positions. And being highly concentrated for a long time is a test for the physical strength and spirit of workers, thus bringing inconvenience to workers. Content of the utility model

[0004] The purpose of the utility model is to provide a bearing drilling device to solve the problems put forward in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A bearing drilling device includes a drilling device body and a clamping component; wherein, the drilling device body includes a machine body, a drill bit and a placing plate; the drill bit is movably connected to the machine body through a moving mechanism; the placing plate is fixedly arranged on the machine body; the clamping component is arranged on the placing plate; wherein, the clamping component includes a moving groove, a bidirectional screw rod, a moving block and a clamping plate; a moving groove is opened on the placing plate; the bidirectional screw rod is rotatably arranged in the moving groove, and the end of the bidirectional screw rod passes through the moving groove and extends to the outside; the two moving blocks are symmetrically sleeved on the bidirectional screw rod, and the end of the moving block passes through the moving groove and extends to the outside; the clamping plate is fixedly connected to the end of the moving block; wherein, the two clamping plates and the placing plate form a clamping cavity for the outer ring of the bearing.

[0006] As a preferred implementation scheme, the moving block is slidably matched with the moving groove, and the moving block is threadedly connected with the bidirectional screw rod.

[0007] As a preferred implementation scheme, the opposite surfaces of the two clamping plates are arc-shaped surfaces, and the top surface of the clamping plate is higher than the center of the arc of the clamping plate.

[0008] As a preferred implementation scheme, it further includes a positioning component; the positioning component is arranged on the clamping plate.

[0009] As a preferred embodiment, the positioning component includes a receiving groove, a positioning plate and an elastic member; at least two receiving grooves are symmetrically formed on the arc surface of the clamping plate; the positioning plate is connected to the receiving groove through two elastic members, and the end of the positioning plate passes through the receiving groove and extends to the outside.

[0010] As a preferred embodiment, the positioning plate includes an extrusion portion and a positioning portion, the extrusion portion has an arc-shaped structure, and the positioning portion contacts the surface of the outer ring of the bearing.

[0011] As a preferred embodiment, the elastic member has an arc-shaped structure, and the arched ends of the two elastic members are arranged on the opposite sides.

[0012] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0013] For this bearing drilling device, by providing a clamping component, during use, first, place the outer ring of the bearing to be drilled between the two clamping plates and the placing plate. Then, rotate the runner on the bidirectional screw rod to thread the movable block with the bidirectional screw rod, so that the two movable blocks slide relatively in the movable groove, causing the two clamping plates to move relatively until the opposite surfaces of the two clamping plates contact the circumferential surface of the outer ring of the bearing. At this time, by starting the drilling device body, the drill bit rotates and moves downward to drill the outer ring of the bearing. The structure of the present utility model is compact and reasonable, and can clamp and fix the outer rings of bearings with different sizes, with strong adaptability.

[0014] For this bearing drilling device, by providing a receiving groove, a positioning plate and an elastic member, the extrusion portion presses the surface of the outer ring of the bearing, causing the positioning portion to tilt, squeezing the outer elastic member and stretching the inner elastic member. After the positioning portion is lifted, as the outer ring of the bearing enters and under the adjustment of the two elastic members, the tilt angle of the positioning portion gradually becomes smaller until the side surface of the positioning portion contacts the surface of the outer ring of the bearing, and both the inner and outer elastic members are in a squeezed state, enabling the positioning plate to clamp the surface of the outer ring of the bearing slowly and gradually, further improving the stability of the position of the outer ring of the bearing.
