When in use, the drilling motor 812 is used to drive the connecting shaft 810 to rotate the automatic loading component 811, so as to start the drill bit 623 installed on the automatic loading component 811, that is, when in use, the automatic loading component 811 is used to clamp and fix the drill bit 623, and then the installation push rod 88 is used to control the position of the drill bit 623, so that the drill bit 623 is moved to a suitable position, and the installation push rod 88 is started to control the height of the drill bit 623, so that the drill bit 623 can act on the bearing, and the drilling motor 812 is started to drive the drill bit 623 to rotate at a high speed, so as to realize the drilling of the bearing. In the present application, the installation push rod 88 is a component that can perform linear motion, and a component that controls the height of the drill bit 623 by an electric telescopic rod or a cylinder.

In this process, the drill bit 623 can be quickly replaced, thereby ensuring the processing efficiency of the bearing.

[0038] Furthermore, the centering mechanism 5 in the present application includes a bottom base 51 fixedly mounted on the counterweight base 41. In the present application, the bottom base 51 is provided with three groups for supporting and limiting the inner ring of the bearing. A pushing telescopic rod 52 is fixed on the bottom base 51, wherein the end of the pushing telescopic rod 52 is provided with a clamping assembly for clamping the inner wall of the bearing. When in use, the three groups of pushing telescopic rods 52 are started with the same length, so that the clamping assemblies are respectively clamped on the inner wall of the bearing, and the angle between adjacent clamping assemblies is 120 degrees, thereby achieving stability in the clamping of the bearing and avoiding movement of the bearing during use.

[0039] The clamping assembly includes a clamping base 54, wherein the clamping base 54 is U-shaped, a clamping telescopic rod 55 is fixed to the side of the clamping base 54, and a clamping plate 53 for further limiting the bearing is fixed to the output end of the clamping telescopic rod 55, that is, when in use, the clamping telescopic rod 55 is used to control the distance of the clamping plate 53, so that the clamping plate 53 is fitted on the bearing, thereby further limiting the position of the bearing, avoiding positional deviation of the bearing, and ensuring the accuracy of bearing drilling.

[0041] In the above technical scheme, the centering mechanism 5 is first controlled so that the centering mechanism 5 is at the lowest end, that is, the distance between the counterweight base 41 and the heavy pressure bottom plate 42 is the smallest. At this time, the telescopic rod 52 is gradually controlled to be pushed so that the telescopic rod 52 drives the clamping base 54 to move until the clamping base 54 is located at the lowest end of the bearing outer ring. Subsequently, the adjustment cylinder 43 is started to increase the distance between the counterweight base 41 and the heavy pressure bottom plate 42.

Subsequently, the clamping telescopic rod 55 is started to move the clamping base 54 toward the outer teeth of the bearing until the limiting teeth 532 act on the outer teeth of the bearing, thereby further limiting the position of the bearing to ensure the stability of the bearing position. In this process, the bearing can be installed so that when the bearing is positioned during drilling, the debris generated can fall directly onto the processing platform under the action of gravity, thereby avoiding interference with the bearing drilling process caused by the debris.

[0042] In order to realize the replacement of the drill bit 623, the tool magazine assembly 6 in the present application includes a tool magazine base 61, wherein the tool magazine base 61 is fixedly installed on the movable end of the telescopic rod 52, and a tool storage magazine 62 for storing the drill bit 623 is installed on the tool magazine base 61, which is used to control the tool storage magazine 62 to approach the processing assembly under the action of the telescopic rod 52, so as to facilitate the replacement of the drill bit 623 by the processing assembly.

Then, by starting the clamping telescopic rod 55, the clamping base 54 is moved toward the outer teeth of the bearing until the limiting teeth 532 act on the outer teeth of the bearing, thereby further limiting the position of the bearing to ensure the stability of the bearing position. In this process, the bearing can be installed so that when the bearing is positioned during drilling, the debris generated can fall directly onto the processing platform under the action of gravity, thereby avoiding interference of the debris on the bearing drilling process;

[0045] After the bearing is centered, the present application first uses the position adjustment mechanism 8 to control the position of the processing assembly so that the processing assembly is transferred to the processing hole position of the bearing, that is, the power motor 73 is started to drive the power gear 71, so that under the meshing action of the power gear 71 and the rotating gear 75, the rotating disk 76 is rotated on the movable connecting rod 3, thereby driving the processing assembly, so that the position of the processing assembly can be adjusted, and the processing assembly can be easily acted on a bearing of a larger size, thereby ensuring the accuracy of the action of the processing assembly, so as to ensure the precise positioning of the processing hole position of the bearing. At the same time, the present application can be provided with multiple groups of supporting flat rods 72 on the rotating disk 76, so that multiple groups of processing assemblies can be arranged at the same time, and multiple groups of processing The assembly can ensure the efficiency of bearing drilling and realize rapid bearing drilling processing; then the power motor 73 is started to drive the power gear 71, so that under the meshing action of the power gear 71 and the rotating gear 75, the rotating disk 76 is rotated on the movable connecting rod 3, thereby driving the processing assembly, so that the position of the processing assembly can be adjusted, and the processing assembly can be easily acted on a bearing with a larger size, thereby ensuring the accuracy of the processing assembly, so as to ensure the precise positioning of the processing hole of the bearing. At the same time, the present application can be provided with multiple groups of supporting flat rods 72 on the rotating disk 76, so that multiple groups of processing assemblies can be provided at the same time. The use of multiple groups of processing assemblies can ensure the efficiency of bearing drilling and realize rapid bearing drilling processing;

[0046] When drilling a bearing, the automatic loading assembly 811 is used to clamp and fix the drill bit 623, and then the installation push rod 88 is used to control the position of the drill bit 623, so that the drill bit 623 is moved to a suitable position. The installation push rod 88 is started to control the height of the drill bit 623 so that the drill bit 623 can act on the bearing, and the drilling motor 812 is started to drive the drill bit 623 to rotate at a high speed, thereby achieving the drilling of the bearing;

[0047] When the drill bit 623 is replaced according to the drilling process of the bearing, the present application first uses the position adjustment mechanism 8 to control the position of the automatic loading component 811, so that the automatic loading component 811 is located above the installation limit seat 621, and then uses the installation push rod 88 to control the height of the automatic loading component 811, so that the automatic loading component 811 can place the original drill bit 623 on the installation limit seat 621, and then replace the applicable drill bit 623, and then move the automatic loading component 811 to the corresponding reprocessing position to achieve fine processing of the drilling.
