[0002] Currently, bearings are an important component in modern mechanical equipment. They are widely used and demanding supporting components and foundational parts in the machinery industry. They are the supporting elements for rotating shafts or moving parts of various machines, and they also support the rotation of the main machine by relying on the rolling of the rolling elements.

[0003] A bearing generally consists of four parts: an inner ring, an outer ring, rolling elements, and a cage. The inner ring cooperates with the shaft and rotates with it; the outer ring cooperates with the bearing seat and provides support; the rolling elements are evenly distributed between the inner and outer rings with the help of the cage, and their shape, size, and number directly affect the performance and life of the rolling bearing; the cage can evenly distribute the rolling elements, guide the rotation of the rolling elements, and provide lubrication.

[0004] Generally, in order to increase the service life of the bearing, oil is injected into the bearing. In order to facilitate the injection of oil, holes are drilled in the outer ring of the bearing so that the oil can be easily injected into the bearing through the holes.

The feeding mechanism comprises a feeding cylinder and a push rod, the feeding cylinder being transversely arranged on the workbench with its driving end correspondingly connected to the tail end of the push rod. The bearing seat is arranged on the workbench and located below the push rod. The positioning mechanism comprises a positioning frame, a positioning cylinder, and a positioning block. The positioning cylinder is longitudinally arranged and fixed to the workbench via the positioning frame. The driving end of the positioning cylinder is arranged downward and fixedly provided with a positioning block corresponding to the upper and lower sides of the bearing seat. The positioning block is also arranged flush with the push rod. The drilling mechanism is arranged on one side of the bearing seat and corresponds to the side of the bearing on the bearing seat. This utility model can automate feeding, positioning, and drilling, effectively reducing labor costs.

[0006] When drilling the outer ring of the bearing, a lot of waste will be generated, and the waste will easily accumulate on the bearing seat. When the outer ring of the bearing is transported to the bearing seat, the waste on the bearing seat will cause the outer ring of the bearing to be placed in a non-horizontal position. When the drill bit drills the outer ring of the bearing, it will affect the drilling position accuracy. Summary of the Invention

When the first slider drives the first guide plate close to the top of the first inclined plate, the first spring is squeezed and the first scraper slides into the first guide groove, so that the bottom of the first scraper can contact the side wall of the first inclined plate.

When one end of the rotating rod rotates past the top of the feeding block, the convex arc surface is slidably connected with the concave arc surface of the arc groove.

[0018] By adopting the above technical solution, after the outer ring of the bearing is processed, the driving part transports the outer ring of the bearing to the bottom of the rotating rod.

After the outer ring of the bearing is transported to the feed block, the first cylinder transports the feed block to the processing gap in the horizontal direction, and the lifting member lowers the feed block in the vertical direction. The outer ring of the bearing is supported by the first inclined plate and the second inclined plate on both sides. The outer ring of the bearing is separated from the feed block, and the drill bit drills a hole in the outer ring of the bearing. After the drilling is completed, the lifting member rises in the vertical direction, and the outer ring of the bearing re-enters the arc groove of the feed block, and the first cylinder outputs the feed block from the processing gap in the horizontal direction.

[0021] Preferably, the first cylinder is connected to a motor, the output shaft of the motor is connected to the housing of the first cylinder, and the first cylinder is connected to the lifting member through the motor.

[0022] By adopting the above technical solution, when the drill bit drills a hole in the outer ring of the bearing, the feed block is located below the outer ring of the bearing, and the motor can rotate the feed block so that the concave arc side of the arc groove faces away from the outer ring of the bearing, thereby minimizing the waste generated when drilling the outer ring of the bearing from entering the arc groove. At the same time, the motor rotates the feed block to throw out the waste in the arc groove.

[0023] Preferably, the lifting member includes a second screw rod and a second guide rod, the length directions of the second screw rod and the second guide rod are distributed in the vertical direction, one end of the motor housing is connected to the slider of the second screw rod, and the other end of the motor housing is slidably sleeved on the second guide rod.

The outer ring of the bearing can vibrate the filter screen, which can vibrate the waste on the filter screen and avoid clogging of the filter screen as much as possible. The outer ring of the bearing can slide off the filter screen along the inclination direction of the filter screen. The baffle can block the outer ring of the bearing and avoid the outer ring of the bearing from falling from both sides of the filter screen as much as possible.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The first scraper moves along the side wall of the first inclined plate to scrape off waste material adhering to the side wall of the first inclined plate. The second scraper moves along the side wall of the second inclined plate to scrape off waste material adhering to the side wall of the second inclined plate. The waste material can be discharged from between the first and second inclined plates through the bottom of the processing gap, thereby reducing waste material on the side walls of the first and second inclined plates. The feeding assembly conveys the bearing outer ring into the processing gap. The side walls of the first and second inclined plates support the bearing outer ring. The drill bit drills the bearing outer ring through the through hole, thereby minimizing the impact of waste material on the position of the bearing outer ring, thereby reducing the impact of waste material on the accuracy of the drill bit's drilling position.

[0031] 2. After the outer ring of the bearing is processed, the driving part transports the outer ring of the bearing to the bottom of the rotating rod. When the rotating rod rotates and passes above the feeding block, one end of the rotating rod can push the outer ring of the bearing out of the arc groove, thereby pushing the outer ring of the bearing into the discharge track. At the same time, when pushing the outer ring of the bearing, one end of the rotating rod can also push the waste in the arc groove out of the arc groove, thereby cleaning the waste in the arc groove and avoiding the accumulation of waste in the arc groove as much as possible, thereby avoiding the impact of the waste on the outer ring of the bearing when the feeding block is conveying the outer ring of the bearing;

[0032] 3. The outer ring of the bearing may fall off during processing and fall onto the filter. The second spring can act as a buffer. The outer ring of the bearing can vibrate the filter, causing the waste on the filter to vibrate, thereby avoiding clogging of the filter.
