Description

Technical Field

[0001] The utility model belongs to the technical field of drilling devices, in particular to a drilling device for bearing processing. Background Art

[0002] As precision mechanical parts, bearings usually need to go through multiple processing steps during the production process, including turning, drilling, grinding, etc. Traditional processing methods may require placing the bearing on a lathe to complete preliminary cutting, and then transferring it to other equipment for special drilling operations.

[0003] In the bearing drilling process, it is often necessary to evenly distribute the circular hole array on the edges of both sides of the bearing. When drilling, the position of the drill bit or the bearing needs to be constantly changed. When changing the position of the drill bit, the drill bit needs to move simultaneously in the XY directions and make a circular motion around the bearing, resulting in a complex structure.

[0004] Therefore, when drilling holes uniformly in a circular array on the edges of both sides of the bearing, in order to easily change the position of the bearing, make the edge of the bearing directly under the drill bit, optimize the structural components, and facilitate operation, a drilling device for bearing processing is urgently needed to solve the existing problems.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a drilling device for bearing processing, comprising a bottom plate, a bracket is fixedly installed on the bottom plate, an upper and lower driving assembly is arranged on the bracket, a drill bit is fixedly installed on the upper and lower driving assembly, that is, the upper and lower driving assembly drives the drill bit to move up and down, that is, the drill bit works on the edge of the bearing, an auxiliary sliding assembly is arranged on the top of the bottom plate, a front and rear driving assembly is arranged above the auxiliary sliding assembly, that is, the auxiliary sliding assembly assists the plate at the bottom of the front and rear driving assembly to slide, that is, the front and rear driving assembly drives the clamping member to move forward and backward, a workbench is fixedly installed on the top of the front and rear driving assembly, and a A first motor, an output shaft of the first motor is connected with a limiting groove, that is, the limiting groove limits the bottom of the bearing, the first motor drives the limiting groove to rotate indirectly, a fixed clamping plate is arranged on one side of the limiting groove, and a vertical plate is installed on the other side of the limiting groove, and a second motor is also arranged on the workbench, a screw rod is connected to the output shaft of the second motor, and a sliding clamping plate is penetrated on the screw rod, that is, the second motor drives the screw rod to rotate, so that the sliding clamping plate moves horizontally and gradually approaches the fixed clamping plate to clamp the middle part of the bearing, and a limiting rod is also penetrated on the upper part of the sliding clamping plate, and one end of the limiting rod is fixedly connected to the vertical plate, that is, the limiting rod limits the sliding clamping plate.

[0007] Both the fixed clamping plate and the sliding clamping plate are equipped with arc-shaped clamping grooves, that is, the arc-shaped clamping grooves clamp the middle part of the bearing. Friction pads are installed on the inner wall of the arc-shaped clamping grooves, that is, the friction pads can increase the friction with the side wall of the bearing. The arc-shaped clamping grooves are arranged to be disassembled and installed for easy replacement.

[0008] The upper and lower drive components and the front and rear drive components are composed of a drive motor, a screw rod, a bearing base, a limit shaft and a connecting plate. The drive motor drives the screw rod to rotate, and the limit shaft prevents the plate passing through the screw rod from deviating.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] Firstly, the bearing is placed inside the limit groove, and the edge of the bearing is located directly below the drill bit. In the process of the clamping member and the first motor driving the limit groove to rotate indirectly, different edges of the bearing are located at the corresponding drill bits respectively. The drill bit only needs to be driven by the upper and lower drive components to complete the uniform array drilling at the edge of one side wall of the bearing. Compared with controlling the drill bit to move in the XY direction to complete the drilling work, the structure of the device is simpler, and the code steps input when the drill bit moves in the XY direction are reduced, which is convenient for the staff to operate.
