Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, and in particular to a multi-position bearing horizontal drilling device that facilitates material replenishment. Background Technology

[0002] The outer ring of a bearing needs to be drilled during manufacturing. This is done to create oil holes for lubrication, which helps extend the bearing's service life. In addition, it can also remove dirt and corrosion products from the inside of the bearing, ensuring its normal operation. It also helps to reduce the overall weight of the bearing.

[0003] In existing bearing drilling equipment, bearings need to be fixed with tooling before drilling. Existing drilling equipment can only clamp and drill a single bearing. Processing different workpieces requires separate positioning, clamping, loading, and unloading, which is cumbersome and results in low efficiency in drilling bearing outer rings, which is not conducive to batch processing of bearing outer rings. Summary of the Invention

[0004] This invention provides a multi-position bearing horizontal drilling device that facilitates material replenishment, in order to solve the problems of existing bearing drilling equipment, which requires tooling fixation before drilling, can only clamp and drill a single bearing, and requires separate positioning, clamping, loading and unloading for different workpieces, which is cumbersome, has low drilling efficiency for bearing outer rings, and is not conducive to batch drilling of bearing outer rings.

[0005] This invention provides a multi-level bearing horizontal drilling device for convenient material replenishment, specifically comprising: a drill base; a bearing support fixedly connected above the drill base; a positioning push cylinder fixedly connected to the left and right edges of the upper surface of the drill base by screws; the push rod of the positioning push cylinder being perpendicular to the upper surface of the drill base; and a bearing drilling machine mounted on the front edge of the upper surface of the drill base, located in front of the bearing support, with the drill bit of the bearing drilling machine perpendicular to the front surface of the drill base. A bearing pressure plate is located above the bearing support. The lower surface of the bearing pressure plate is fixedly connected to the push rod of the positioning push cylinder. The right surface of the bearing support is fixedly connected to a feeding push cylinder via a bracket. The end of the push rod of the feeding push cylinder is fixedly connected to a feeding slider. A rear support is fixedly connected to the rear of the drill base. A reset pull table is movably connected above the rear support. A compensation push table is movably connected in front of the reset pull table. A feeding slider is movably connected to the right side of the compensation push table. The compensation push table is movably connected to the upper surface of the bearing support.

[0006] Furthermore, four vertical guide rods are welded to the upper surface of the drill base. The vertical guide rods are perpendicular to the upper surface of the drill base, and the four vertical guide rods are located at the four apex positions of the upper surface of the drill base.

[0007] Furthermore, a pressure plate guide hole is longitudinally opened at each of the four apex positions of the bearing pressure plate, and four vertical guide rods are slidably connected to the four pressure plate guide holes. The bearing pressure plate is parallel to the upper surface of the bearing support, and a synchronous pressure block is fixedly connected to the lower surface of the bearing pressure plate.

[0008] Furthermore, a pressure plate pusher is fixedly connected to the rear edge of the lower surface of the bearing pressure plate, and the bottom of the pressure plate pusher is provided with an inclined structure facing forward and downward.

[0009] Furthermore, the upper surface of the bearing support has a front edge protruding with a support limiting stop, and the upper surface of the bearing support has a bearing unloading port on the right side.

[0010] Furthermore, the bottom surface of the bearing discharge port is a forward-sloping surface, and a discharge ramp is provided in front of the opening of the bearing discharge port. The discharge ramp is installed on the front surface of the bearing support by screws.

[0011] Furthermore, two guide rods are fixedly connected to the upper surface of the rear support, and a slider is fixedly connected to the lower surface of the reset pull platform. The reset pull platform and the rear support are slidably connected through the guide rods and the slider.

[0012] Furthermore, a reset slider is fixedly connected to the front of the reset pull platform, a reset tension spring is fixedly connected to the reset pull platform, and a rear support is fixedly connected to the rear end of the tension spring.

[0013] Furthermore, the front edge of the compensation pusher is provided with six arc-shaped bearing positioning holes, and the rear edge of the compensation pusher is connected to a reset guide rod by screws, and the reset guide rod is slidably connected to the reset slider.

[0014] Furthermore, a feeding guide rod is fixedly connected to the right edge of the compensation pusher, and the feeding guide rod is slidably connected to the feeding slider. Two pusher rollers are rotatably connected to the upper rear edge of the compensation pusher, and the two pusher rollers are respectively rotatably connected to the inclined surfaces of the two pressure plate pushers.

[0015] This invention provides a multi-level bearing horizontal drilling device that facilitates material replenishment, and has the following beneficial effects: In the bearing horizontal drilling equipment of this invention, the bearing support and the compensation pusher can simultaneously center and lock the outer rings of six bearings. During the bearing drilling process, the bearing drilling machine drills the bearings located at the drilling positions. After drilling is completed, the compensation pusher is moved by the feeding cylinder, causing the bearings located on the left side of the drilling positions to move to the drilling positions for compensation. Multiple bearings can be placed at a time, allowing the bearings located on the left side of the drilling positions to enter the drilling positions sequentially for compensation, achieving completely continuous drilling of multiple bearings. Compared with the traditional method of feeding single workpieces separately, the batch feeding and automatic feeding function effectively reduces the tediousness of manual operation and improves the efficiency of batch drilling of bearings.

[0016] In addition, an automatic unloading structure with bearing outer ring is provided. The bearing outer ring, which is drilled by the bearing drilling machine, slides down into the bearing unloading port under the pull of the feeding cylinder on the compensation push table. It then slides forward through the bearing unloading port and the inclined surface of the unloading inclined plate, realizing the automatic unloading of the finished workpiece.

[0017] In addition, the compensating pusher has the function of moving forward, backward, left, and right. After the bearing is drilled, the positioning pusher cylinder pushes the bearing pressure plate upward by 1-2mm, separating the synchronous pressure block from the bearing. At this time, the feeding pusher cylinder is controlled to retract, pulling the compensating pusher to the right. This causes the bearing located inside the adjacent bearing positioning port to move a certain distance to the right and enter the front of the bearing drilling machine. The bearings inside the remaining bearing positioning ports follow suit and move to the right to compensate. Then, the positioning pusher cylinder continues to push the bearing pressure plate upward, causing the pressure plate pusher frame to move upward. As the pressure plate pusher frame moves upward, the pusher roller rolls on the inclined surface of the pressure plate pusher frame. Under the tension of the return spring, the compensating pusher moves backward, separating the bearing positioning port from the bearing. In this state, the compensation pusher is pushed to the left again to its original left and right position by the material replenishment pusher cylinder, and the positioning pusher cylinder is controlled to retract. As the bearing pressure plate moves down, the compensation pusher pushes forward under the rolling action of the pressure plate pusher inclined surface and the pusher roller, so that the outer surface of the bearing is in contact with the bearing positioning port again. The bearing is locked by the support limit front stop and the bearing positioning port. With the synchronous pressure block pressing on the upper end face of the bearing, the axial direction of the bearing is locked, so that the bearing is firmly fixed above the bearing support. It can be seen that the bearing replenishment function of this application has a multi-directional movement function. The multi-directional movement function allows the bearing to return to its original position after a single replenishment, thereby realizing the continuous replenishment of multiple bearings.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figures 1 to 12 : This invention proposes a multi-level bearing horizontal drilling device for convenient material replenishment, comprising: a drill base 1, a bearing support 2 fixedly connected above the drill base 1, a support limiting front stop 201 protruding from the front edge of the upper surface of the bearing support 2, a positioning push cylinder 3 fixedly connected to the left and right edges of the upper surface of the drill base 1 by screws, the push rod of the positioning push cylinder 3 being perpendicular to the upper surface of the drill base 1, and a bearing drilling machine 4 installed on the front edge of the upper surface of the drill base 1, the bearing drilling machine 4 being located on the bearing support 2. At the front, the drill bit of the bearing drilling machine 4 is perpendicular to the front surface of the drill base 1. A bearing pressure plate 5 is located above the bearing support 2. The lower surface of the bearing pressure plate 5 is fixedly connected to the push rod of the positioning push cylinder 3. The right surface of the bearing support 2 is fixedly connected to the feeding push cylinder 6 via a bracket. The end of the push rod of the feeding push cylinder 6 is fixedly connected to the feeding slider 601. A rear support 102 is fixedly connected to the rear of the drill base 1. A reset pull table 7 is movably connected above the rear support 102. A compensation push table 8 is movably connected in front of the reset pull table 7. The compensation pusher 8 is movably connected to the feeding slider 601 on its right side, and the compensation pusher 8 is movably connected to the upper surface of the bearing support 2. During the bearing drilling process, the bearing is located inside the bearing positioning port 801. The bearing positioning port 801 and the support limiting front stop 201 are tightly fitted with the bearing to lock the radial direction of the bearing, preventing radial runout or vibration of the bearing during drilling. The positioning pusher 3 pulls the bearing pressure plate 5 downward, so that the synchronous pressure block 503 is tightly fitted with the upper end face of the bearing, thus axially positioning the bearing. Tightening prevents axial runout or vibration of the bearing during drilling. The feeding pusher 6 allows the compensation pusher 8 to move left and right, moving the outer ring of the completed bearing out of the drilling position and pushing the adjacent left bearing to the right to the drilling position to complete the automatic feeding process of the bearing outer ring. The bearing located on the left side of the drilling position moves to the drilling position for compensation. Multiple bearings can be put in at one time, so that the bearings located on the left side of the drilling position enter the drilling position in sequence for compensation, realizing complete continuous drilling of multiple bearings.

[0024] In this embodiment, four vertical guide rods 101 are welded to the upper surface of the drill base 1. The vertical guide rods 101 are perpendicular to the upper surface of the drill base 1. The four vertical guide rods 101 are located at the four apex positions of the upper surface of the drill base 1. A pressure plate guide hole 501 is longitudinally opened at each of the four apex positions of the bearing pressure plate 5. The four pressure plate guide holes 501 are slidably connected to the four vertical guide rods 101 to play a guiding role. The bearing pressure plate 5 is parallel to the upper surface of the bearing support 2. A synchronous pressure block 503 is fixedly connected to the lower surface of the bearing pressure plate 5. The axial clamping and locking of the outer ring of the bearing is achieved by the tight fit between the synchronous pressure block 503 and the bearing end face.

[0025] In this embodiment, two guide rods are fixedly connected to the upper surface of the rear support 102, and a slider is fixedly connected to the lower surface of the reset pull platform 7. The reset pull platform 7 and the rear support 102 are slidably connected through the guide rods and the slider. A reset slider 701 is fixedly connected to the front of the reset pull platform 7, and a reset tension spring 702 is fixedly connected to the reset pull platform 7. The rear end of the tension spring 702 is fixedly connected to the rear support 102.

[0026] In this embodiment, the front edge of the compensation pusher 8 is provided with six arc-shaped bearing positioning ports 801, and the rear edge of the compensation pusher 8 is connected to a reset guide rod 802 by screws. The reset guide rod 802 is slidably connected to the reset slider 701. Through the slidable connection between the reset guide rod 802 and the reset slider 701, the compensation pusher 8 has a guiding function under the left and right pushing action of the feeding cylinder 6, so that the compensation pusher 8 moves smoothly left and right under the push of the feeding cylinder 6.

[0027] Furthermore, a pressure plate pusher 502 is fixedly connected to the rear edge of the lower surface of the bearing pressure plate 5. The bottom of the pressure plate pusher 502 has an inclined structure facing forward and downward. A feeding guide rod 803 is fixedly connected to the right edge of the compensation pusher 8. The feeding guide rod 803 is slidably connected to the feeding slider 601. Through the sliding connection between the feeding slider 601 and the feeding guide rod 803, the compensation pusher 8 has a guiding function when moving back and forth, so that the compensation pusher 8 moves back and forth smoothly and avoids deflection during the movement of the compensation pusher 8. Two pusher rollers 804 are rotatably connected to the upper rear edge of the compensation pusher 8. The two pusher rollers 804 are respectively rolledly connected to the inclined surfaces of the two pressure plate pushers 502. Under normal conditions... The pusher roller 804 is connected to the inclined surface of the pressure plate pusher 502 in a rolling connection. As the bearing pressure plate 5 moves down, the pressure plate pusher 502 moves down. Under the action of the inclined surface of the pressure plate pusher 502, the compensating pusher 8 is pushed forward. The bearing is locked through the bearing positioning port 801. After the bearing pressure plate 5 moves up and resets, the compensating pusher 8 is pulled backward by the tension of the reset spring 702, realizing the automatic removal of the compensating pusher 8 and separating the bearing positioning port 801 from the bearing. Through the cooperation of the secondary transmission structure, the forward push and backward pull of the compensating pusher 8 do not require an additional drive mechanism, reducing the control difficulty and the manufacturing cost of the equipment, and realizing the high-synchronization of the bearing pressure plate 5 and the compensating pusher 8.

[0028] In Example 2, based on Example 1, a bearing unloading port 202 is provided on the right side of the upper surface of the bearing support 2. The bottom surface of the bearing unloading port 202 is a forward-sloping surface. A discharge ramp 203 is provided in front of the opening of the bearing unloading port 202. The discharge ramp 203 is installed on the front surface of the bearing support 2 by screws. The outer ring of the bearing, which has been drilled by the bearing drilling machine 4, slides down into the bearing unloading port 202 under the pull of the feeding push cylinder 6 on the compensation push table 8, and slides forward through the bearing unloading port 202 and the slope of the discharge ramp 203, thereby realizing the automatic discharge of the finished workpiece.

[0029] The working principle of this embodiment is as follows: First, the positioning push cylinder 3 is controlled to push the bearing pressure plate 5 upward, increasing the gap between the bearing pressure plate 5 and the bearing support 2. Six bearings requiring drilling are then arranged laterally above the bearing support 2 and aligned with the front opening of the corresponding bearing positioning port 801. During drilling, the positioning push cylinder 3 is controlled to retract. As the bearing pressure plate 5 moves downward, the rolling action of the inclined surface of the pressure plate push frame 502 and the push table roller 804 causes the push table 8 to move forward, compensating for the downward movement of the push table. This causes the outer surface of the bearing to fit against the bearing positioning port 801, and the support limits the movement. The front guard 201 and the bearing positioning port 801 lock the bearing, and as the synchronous pressure block 503 presses against the upper end face of the bearing, the axial direction of the bearing is locked, so that the bearing is firmly fixed above the bearing support 2. The bearing drilling machine 4 is controlled to drill a hole in the outer ring of the bearing located behind it. After the drilling is completed, the positioning push cylinder 3 pushes the bearing pressure plate 5 upward by 1-2mm, so that the synchronous pressure block 503 is separated from the bearing. At this time, the feeding push cylinder 6 is controlled to retract, and the compensation push table 8 is pulled to the right, so that the bearing located inside the adjacent bearing positioning port 801... The bearing positioning port 8 moves a certain distance to the right and enters the front of the bearing drilling machine 4. The bearings inside the remaining bearing positioning ports 801 follow suit and move to the right to compensate. Then, the positioning push cylinder 3 continuously pushes the bearing pressure plate 5 upward, causing the pressure plate pusher 502 to move upward. As the pressure plate pusher 502 moves upward, the pusher roller 804 rolls on the inclined surface of the pressure plate pusher 502. Under the tension of the return spring 702, the compensation pusher 8 moves backward, separating the bearing positioning port 801 from the bearing. In this state, the compensation pusher 8 is pushed to the left again by the feeding pusher 6 to its original left and right positions. The control positioning push cylinder 3 retracts, and as the bearing pressure plate 5 moves down, the rolling action of the pressure plate push frame 502 inclined surface and the push table roller 804 pushes the lowering compensation push table 8 forward, so that the outer surface of the bearing is in contact with the bearing positioning port 801 again. The bearing is locked by the support limit front stop 201 and the bearing positioning port 801. As the synchronous pressure block 503 squeezes the upper end face of the bearing, the axial direction of the bearing is locked, so that the bearing is firmly fixed above the bearing support 2. The bearing drilling machine 4 continues to drill holes in the bearing outer ring at the corresponding position.
