Description

Technical Field

[0001] The utility model relates to the technical field of bearing seat processing, in particular to a hole-making device for bearing seat processing. Background Art

[0002] In the production and processing of bearing seats, drilling is a crucial step. The bearing seat is used to support the bearing and fix the outer ring of the bearing, allowing only the inner ring to rotate while the outer ring remains stationary. It is always consistent with the direction of transmission (such as the direction of motor operation) and maintains balance. During the drilling process, the drill bit and the inner wall of the bearing seat produce friction, which will generate a lot of heat. Generally, coolant is sprayed onto the contact surface between the drill bit and the inner wall of the bearing seat to cool it down. However, during the cooling process, when the drill bit rotates at high speed and drills deep, the coolant may be difficult to fully cover all contact surfaces, failing to achieve the ideal cooling effect.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example

[0020] See also Figure 1-Figure 4The figure shows a hole-punching device for processing a bearing seat, including a base 1, which is fixedly connected to a positioning fixture 2. A drill bit 3 is provided above the positioning fixture 2. The drill bit 3 is threadedly connected to the inside of an output shaft 4. The output shaft 4 is meshed with one end of a rotating shaft 5, and the other end of the rotating shaft 5 is meshed with an input shaft 6. A water tank 7 is provided on one side of the rotating shaft 5. The water tank 7 is fixedly connected to a water inlet 8. The water tank 7 is threadedly connected to a shell 9. The shell 9 is fixedly connected to a connecting block 10. A motor 11 is provided above the shell 9. The connecting block 10 is fixedly connected to a moving body 12. The moving body 12 is fixedly connected to the base 1 The utility model provides a drill bit above the positioning fixture, and the drill bit is threadedly connected to the inside of the output shaft. One end of the output shaft is meshed with the rotating shaft, and the other end of the rotating shaft is meshed with the input shaft. A water tank is provided on one side of the rotating shaft, and the water inlet of the water tank is fixedly connected to the water tank. The water tank is threadedly connected to the shell, and the shell is fixedly connected to the connecting block, and the connecting block is fixedly connected to the mobile body. During use, the coolant in the water tank can enter the drill bit through the output shaft and contact the workpiece, so that the coolant can more fully cover all contact surfaces, thereby achieving an ideal cooling effect.

[0021] Furthermore, the interior of the output shaft 4 is hollow, and a locking rod 13 is provided inside the output shaft 4. The locking rod 13 tightly presses the outer wall of the drill bit 3. The interior of the output shaft is hollow, which provides a convenient channel for the circulation of coolant. During the drilling process, the coolant can be directly transported to the contact part between the drill bit and the workpiece through this hollow channel, thereby achieving effective cooling and lubrication of the drill bit. A locking rod is also provided inside the output shaft, and the locking rod tightly presses the outer wall of the drill bit, ensuring the stability of the drill bit during rotation and preventing it from loosening or falling off.

[0022] Furthermore, the interior of the drill bit 3 is hollow and connected to the interior of the output shaft 4. A water outlet is provided at one end of the drill bit 3. The interior of the drill bit is hollow and connected to the interior of the output shaft, which greatly facilitates the circulation of the coolant, so that the coolant can be directly delivered to the interior of the drill bit through the output shaft. A water outlet is also provided at one end of the drill bit. During the drilling process, the coolant can be directly sprayed through the water outlet to the contact part between the drill bit and the workpiece, achieving instant cooling and lubrication of the drill bit, ensuring that the drill bit can always maintain a low temperature during high-speed rotation and deep drilling, thereby effectively reducing friction and wear and extending the service life of the drill bit.

[0023] Furthermore, one end of the input shaft 6 is plugged into the motor 11, and the other end of the input shaft 6 is rotatably connected to the inside of the housing 9. By plugging one end of the input shaft into the motor, a stable connection between the input shaft and the motor is ensured, so that the rotational power of the motor can be efficiently transmitted to the input shaft. When the motor starts, the rotational power it generates is transmitted to the entire transmission system through the input shaft, and finally drives the drill bit to perform drilling operations.

[0024] Furthermore, motor 11 is fixedly connected to connecting block 10, which is in turn fixedly connected to the moving block of mobile body 12. This fixed connection between the motor and the connecting block ensures the stability of the motor during drilling operations, preventing it from shaking or shifting during operation, thereby ensuring the accuracy and stability of drilling. Furthermore, the fixed connection of the motor allows the rotational power it generates to be more stably and efficiently transmitted to the transmission system, ultimately driving the drill bit to perform the drilling operation.

[0025] Furthermore, the rotating shaft 5 is provided inside the shell 9, and the rotating shaft 5 is rotatably connected to the inside of the shell 9. The rotating shaft is cleverly arranged inside the shell and is connected to the inside of the shell through a rotating connection, so that the rotating shaft can rotate freely inside the shell during the power transmission process without being subjected to excessive friction or resistance, thereby ensuring the smooth operation of the transmission system.

[0026] In this solution, the working process is as follows: first, the bearing seat to be processed is fixed on the positioning fixture 2; then, the motor 11 is started to drive the drill bit 3 to rotate through the transmission system of the input shaft 6, the intermediate shaft 5 and the output shaft 4; at the same time, the coolant is sprayed through the channel and the water outlet inside the drill bit 3 to the contact part between the drill bit and the workpiece; finally, the drill bit 3 performs the drilling operation stably under the cooling and lubricating effect of the coolant until the processing process is completed.
