Description

Technical Field

[0001] This invention relates to the technical field of intelligent manufacturing equipment, and in particular to an automatic drilling and deburring machine tool for bearing outer rings. Background Technology

[0002] In the field of intelligent manufacturing, a highly efficient and precise production solution has been built based on automatic drilling and deburring machines for bearing outer rings and intelligent manufacturing equipment. The automatic drilling and deburring machine for bearing outer rings, with its automated operation process, can complete the drilling operation of bearing outer rings and effectively remove burrs generated during processing, thereby improving the stability of product quality.

[0003] According to the search, CN114473503B discloses an automatic drilling and deburring device and process for bearing outer rings, which includes: after the bearing ring enters the interior of the automatic drilling and deburring machine, four drill bits are driven by a cylinder to drill holes in the bearing ring. After drilling, the bearing ring is picked up by a robot and placed on the deburring device to grind and remove the burrs caused by drilling. The deburred bearing ring is then placed on the unloading track.

[0004] However, the inventors discovered during practical application that, because current bearing outer ring drilling and deburring devices are performed in two separate processes, after drilling, a robotic arm is needed to pick up the bearing outer ring and send it to the grinding process. This process places relatively strict requirements on the precision of the robotic arm's gripping and placement. In actual operation, positioning misalignment can easily occur due to factors such as movement of the bearing outer ring during transport. Once positioning misalignment occurs, the subsequent grinding process cannot perform normal grinding work, thus affecting the smooth progress of the entire production process and the stability of product quality. Summary of the Invention

[0005] This invention proposes an automatic drilling and deburring machine for bearing outer rings, which has the advantage of drilling and grinding the fixed bearing outer ring sequentially, thereby solving the problem mentioned in the background art that the bearing outer ring needs to be positioned multiple times due to different processes in grinding and drilling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic drilling and deburring machine for bearing outer rings, comprising: a machine base, on which a transverse reciprocating assembly for driving a transverse slide to reciprocate is mounted; a positioning base, fixed in the middle of the machine base, for placing the bearing outer ring; a polishing assembly and a drilling assembly, symmetrically arranged on the surface of the transverse slide, with the center lines of the polishing assembly and the drilling assembly aligned; when the transverse reciprocating assembly drives the transverse slide to move forward, the drilling assembly first drills holes in the bearing outer ring; when the transverse reciprocating assembly subsequently drives the transverse slide to move in the reverse direction, the polishing assembly polishes the drilled holes.

[0007] Furthermore, a vertical reciprocating assembly that drives the vertical slide to move up and down is installed on the back of the base. A limiting dynamic pressure tube is fastened to the side of the vertical slide, and a positioning pressure plate is movably installed at the bottom end of the limiting dynamic pressure tube. The positioning pressure plate presses the outer ring of the bearing to achieve center alignment and limit positioning.

[0008] Furthermore, the positioning pressure table is shaped like a frustum.

[0009] Furthermore, the top of the limiting dynamic pressure tube is connected to the coolant pump, a positioning fluid hole communicating with the inner cavity of the limiting dynamic pressure tube is opened at the bottom of the outer side of the limiting dynamic pressure tube, a detection fluid hole is opened at the bottom of the limiting dynamic pressure tube, a fluid delivery hole is opened at the bottom of the positioning pressure platform, and a spring is fixedly connected between the limiting dynamic pressure tube and the positioning pressure platform.

[0010] Furthermore, there are multiple positioning fluid holes, and these multiple positioning fluid holes are arranged in a ring at equal angles.

[0011] Furthermore, the diameter of the detection liquid hole is smaller than the diameter of the positioning liquid hole.

[0012] Furthermore, a directional cylinder is threadedly connected to one side of the positioning pressure table, and a telescopic liquid storage component is fixedly connected to the bottom of the inner side of the directional cylinder. A liquid storage hole communicating with the telescopic liquid storage component is opened inside the positioning pressure table. A detection piston is fixedly connected to the top of the telescopic liquid storage component, and a spring is fixedly connected between the top of the detection piston and the top of the inner side of the directional cylinder.

[0013] Furthermore, an overflow pipe is provided on the top of the outer side of the directional cylinder, which is arranged towards the outer ring of the bearing. An overflow groove is provided inside the detection piston. The overflow groove is connected to the overflow pipe to allow the coolant inside the telescopic liquid storage assembly to be discharged outward.

[0014] Furthermore, a positioning detection switch is fixedly installed on the top of the directional cylinder. After the positioning detection switch is activated, a drilling start signal is input to the control system.

[0015] Furthermore, an adjusting rod extending from the side of the directional cylinder is fixedly installed on the side of the detection piston, and a limiting rod is movably installed on the back of the transverse slide, with a torsion spring provided between the limiting rod and the transverse slide.

[0016] The present invention has the following beneficial effects:

[0017] This invention provides an automatic drilling and deburring machine for bearing outer rings. The machine base surface features polishing and drilling components positioned symmetrically on both sides of the bearing outer ring. These two components not only move synchronously but also have their central axes aligned. During actual processing, after the bearing outer ring is clamped onto the surface of the positioning base, the transverse slide moves to the left, bringing the drilling component closer to the bearing outer ring. At this point, the drilling component first performs the drilling operation on the bearing outer ring. After successfully completing the drilling task, the transverse slide moves to the right. This movement causes the polishing component to move to the drilling position and begin polishing the newly drilled hole. The polishing component effectively removes burrs around the drilled hole, making the drilled surface smooth and flat, thus improving the processing quality and overall performance of the bearing outer ring.

[0018] Throughout the entire machining process, the bearing outer ring is firmly clamped onto the locating base, remaining in the same position. This design ensures that the machining areas of the polishing and drilling components can precisely target the same location on the bearing outer ring, avoiding machining errors caused by positional deviations.

Detailed Implementation

[0027] 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 embodiments of the present invention, and not all embodiments. Based on the 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.

[0028] Example 1, please refer to Figure 1 As can be seen, a transverse slide 301 is movably mounted on the surface of the base 1, and the transverse slide 301, constrained by the T-slot, can only perform horizontal reciprocating motion along the surface of the base 1. A transverse reciprocating assembly 3 for driving the transverse slide 301 is fixedly mounted on the side of the base 1. The transverse reciprocating assembly 3 is preferably a combination of a servo motor and a lead screw, but other methods that can achieve this action are not excluded. Specifically, the servo motor is fixedly mounted on the side of the base 1, and a lead screw is fixedly mounted on the output end of the servo motor. The lead screw is threadedly connected to the side of the transverse slide 301. In this way, when the servo motor drives the lead screw to rotate forward and backward, it can drive the transverse slide 301 to perform horizontal reciprocating motion along the surface of the base 1.

[0029] A positioning base 6, bolted to the center of the base 1, is used to place the outer ring of the bearing. A polishing assembly 4 and a drilling assembly 5 are symmetrically arranged on the surface of the transverse slide 301, located on both sides of the outer ring of the bearing. Since both the polishing assembly 4 and the drilling assembly 5 are fixedly mounted on the transverse slide 301, when the transverse slide 301 moves left and right, it can synchronously drive the polishing assembly 4 and the drilling assembly 5 to move left and right. Specifically, the polishing assembly 4 consists of a polishing rod and a motor, while the drilling assembly 5 consists of a drill rod and a motor. The motor can drive either the polishing assembly 4 or the drilling assembly 5 to rotate at a constant speed.

[0030] The polishing rod on polishing assembly 4 and the drilling center axis on drilling assembly 5 are aligned, with the center line passing radially through the center of the bearing outer ring. In this way, once the bearing outer ring is placed on the surface of positioning base 6 and positioned, as shown... Figure 1 and Figure 3As shown, the transverse reciprocating assembly 3 controls the transverse slide 301 to move to the left first. At this time, the drilling assembly 5 approaches the outer ring of the bearing to realize the drilling work of the outer ring of the bearing. As the transverse reciprocating assembly 3 drives the transverse slide 301 to move to the left continuously, the drilling assembly 5 eventually drills a hole along the radial direction of the outer ring of the bearing until it is penetrated.

[0031] After the drilling assembly 5 completes the drilling operation, the transverse reciprocating assembly 3 drives the transverse slide 301 to move to the right. The transverse slide 301 drives the drilling assembly 5 to move away from the outer ring of the bearing. At the same time, the polishing assembly 4 approaches the outer ring of the bearing and eventually enters the drilling area. The polishing assembly 4 is used to grind and polish the drilling area to ensure that the drilled surface becomes smooth and flat. After the polishing assembly 4 has completely passed through the drill hole, the transverse slide 301 drives the polishing assembly 4 to move to the left and withdraw from the outer ring of the bearing, thus completing the drilling and polishing of the outer ring of the bearing.

[0032] In summary, the bearing outer ring drilling and deburring device proposed in this application utilizes the transverse slide 301 to drive the polishing assembly 4 and the drilling assembly 5 for precise left and right guidance. Subsequently, the bearing outer ring is constrained at the top of the positioning base 6, thus ensuring that the drilling and polishing of the bearing outer ring are completed sequentially under the same positioning reference.

[0033] Example 2 is a further improvement on Example 1. Please refer to Example 1. Figure 1 , Figure 3 and Figure 4 It can be seen that a vertical reciprocating assembly 2 is bolted to the back of the base 1, and a vertical slide 201 is movably mounted on the side of the vertical reciprocating assembly 2. The vertical reciprocating assembly 2 drives the vertical slide 201 to move vertically up and down. Specifically, the vertical reciprocating assembly 2 consists of a bracket and a hydraulic cylinder, but other methods to achieve this action are not excluded. The hydraulic cylinder is fixed to the top of the bracket, and the hydraulic rod is fixedly connected to the vertical slide 201, thereby controlling the vertical up and down movement of the vertical slide 201. A limiting dynamic pressure pipe 7 is fastened to the side of the vertical slide 201, and a positioning pressure plate 8 is movably mounted at the bottom end of the limiting dynamic pressure pipe 7. Combined with... Figures 3-5 It can be seen that the positioning pressure table 8 is shaped like a frustum, with the smaller diameter area located at the bottom.

[0034] In practical application, the outer ring of the bearing is placed on the surface of the positioning base 6. Then, the vertical slide 201 is driven vertically downwards by the vertical reciprocating assembly 2. When the positioning pressure table 8 contacts the inner side of the outer ring of the bearing, the bearing is positioned and aligned using the truncated cone-shaped inclined surface of the positioning pressure table 8 until the central axis of the bearing is aligned with the central axis of the limiting pressure tube 7. Finally, the drilling and polishing of the outer ring of the bearing are completed according to the procedures described in Embodiment 1.

[0035] Example 3 is a further improvement on Example 2. Please refer to Example 2. Figures 3-5 It can be seen that the top of the limiting dynamic pressure pipe 7 is generally connected to the coolant pump, and the coolant pump continuously supplies coolant into the limiting dynamic pressure pipe 7. A positioning fluid hole 701, communicating with the inner cavity of the limiting dynamic pressure pipe 7, is opened at the bottom outer side of the limiting dynamic pressure pipe 7. There are multiple positioning fluid holes 701, and these holes are arranged in a ring at equal angles. A detection fluid hole 702, communicating with the inner cavity of the limiting dynamic pressure pipe 7, is opened at the bottom of the limiting dynamic pressure pipe 7. The diameter of the detection fluid hole 702 is smaller than the diameter of the positioning fluid hole 701. A corresponding delivery hole 801 is opened at the bottom of the positioning pressure platform 8. Combined with... Figure 4 It can be seen that a spring is fixedly connected between the limiting pressure pipe 7 and the positioning pressure plate 8. Under normal conditions, the spring pushes the bottom end of the limiting pressure pipe 7 away from the bottom of the positioning pressure plate 8. At this time, when the coolant pump inputs coolant into the limiting pressure pipe 7, the coolant in the positioning fluid hole 701 and the detection fluid hole 702 can be discharged from the delivery hole 801, which can discharge a large volume of coolant. When the positioning pressure plate 8 presses against the outer ring of the bearing, as... Figure 4 As shown, the limiting pressure tube 7 continues to be pressed downwards, so that the bottom end of the limiting pressure tube 7 is pressed against the bottom of the positioning pressure plate 8. At this time, the coolant in the inner cavity of the limiting pressure tube 7 can only be pumped in a small amount from the detection liquid hole 702 to the liquid delivery hole 801.

[0036] Combination Figures 3-5 It can be seen that a guide cylinder 9 is threadedly connected to one side of the surface of the positioning platform 8, and a telescopic liquid storage component 14 is fixedly connected to the bottom of the inner side of the guide cylinder 9. The telescopic liquid storage component 14 is such as a telescopic liquid bladder or a telescopic tube. At the same time, a liquid storage hole 802 is opened inside the positioning platform 8 for communication between the telescopic liquid storage component 14 and the bottom of the positioning platform 8. A detection piston 15 is fixedly connected to the top of the telescopic liquid storage component 14, and a spring is fixedly connected between the top of the detection piston 15 and the top of the inner side of the guide cylinder 9. The detection piston 15 is pushed by the spring, so that it always tends to squeeze the telescopic liquid storage component 14, forcing the medium in the telescopic liquid storage component 14 to always tend to be discharged into the liquid storage hole 802.

[0037] from Figure 5As can be seen, an overflow pipe 13 is provided on the top outer side of the directional cylinder 9, facing the outer ring of the bearing. Correspondingly, an overflow groove 150 is provided in the detection piston 15. Under normal conditions, the detection piston 15, pushed by the spring, moves downward and presses down on the telescopic liquid storage assembly 14, causing the overflow groove 150 to move relatively away from the directional cylinder 9. At this time, the overflow groove 150 is blocked by the inner wall of the directional cylinder 9. When the detection piston 15 moves to the top, the overflow groove 150 connects with the overflow pipe 13, thereby discharging the coolant inside the telescopic liquid storage assembly 14 outward from the overflow groove 150 and the overflow pipe 13. Furthermore, when the detection piston 15 moves to the top, it will touch the position detection switch 12 fixedly installed on the top of the directional cylinder 9. The position detection switch 12 will input a drilling start signal to the control system (such as a programmable control system), thereby instructing the subsequent drilling assembly 5 to perform drilling operations.

[0038] Moreover, combined Figures 2-5 It can be seen that an adjusting rod 10 extending from the side of the directional cylinder 9 is fixedly installed on the side of the detection piston 15. One end of the adjusting rod 10 is movably mounted on the vertical reciprocating assembly 2, and ultimately, the adjusting rod 10 can only move up and down. A limiting rod 11 is movably installed on the back of the transverse slide 301. The length of the limiting rod 11 can be selected independently, and a torsion spring is provided between the limiting rod 11 and the transverse slide 301. Under normal conditions, the limiting rod 11 is in a vertically arranged state due to the action of the torsion spring. Figure 2 As shown in the diagram. When the drilling assembly 5 needs to drill a hole in the outer ring of the bearing, it is necessary to ensure that the adjusting rod 10 passes over the top of the limiting rod 11 to avoid the adjusting rod 10 obstructing the movement of the limiting rod 11.

[0039] In the specific application of this embodiment 3, the vertical reciprocating component 2 lifts the vertical slide 201 and moves it away from the positioning base 6. At this time, the positioning pressure table 8 is pushed down by the spring, so that the coolant sprayed from the positioning liquid hole 701 and the detection liquid hole 702 can be ejected from the liquid inlet 801.

[0040] The outer ring of the bearing to be processed is placed on the surface of the positioning base 6. Then, coolant is pumped out from the pressure limiting pipe 7. The coolant is simultaneously sprayed into the delivery hole 801 through the positioning fluid hole 701 and the detection fluid hole 702. The delivery hole 801 sprays a vertical jet downwards. After the jet passes through the inside of the bearing outer ring and hits the surface of the positioning base 6, the jet will diverge radially (i.e., jet diffusion). If the initial position of the bearing outer ring is off-center, the flow resistance of the jet on both sides of the bearing outer ring will be asymmetrical. The bearing will automatically adjust its position under the action of the fluid and eventually reach a state of force balance. At this time, the center of the bearing coincides with the axis of the jet.

[0041] When the vertical reciprocating assembly 2 drives the limiting pressure tube 7 to move downward continuously through the vertical slide 201, the positioning pressure table 8 will eventually press against the inner side of the outer ring of the bearing. At this time, the outer frustum inclined surface of the positioning pressure table 8 is used for precise positioning.

[0042] As the limiting pressure tube 7 continues to press downwards, its bottom end reaches the bottom of the inner side of the positioning pressure plate 8. At this point, the coolant in the inner cavity of the limiting pressure tube 7 can only be input into the inner side of the bearing outer ring through the detection fluid hole 702. Since the amount of coolant output from the detection fluid hole 702 is relatively small, if a positioning deviation occurs between the positioning pressure plate 8 and the bearing, the coolant will leak from the gap between the bearing outer ring and the positioning pressure plate 8. Due to this leakage, after the coolant enters the telescopic accumulator assembly 14, it cannot cause the detection piston 15 to move upwards and compress the spring. Subsequently, the detection piston 15 cannot contact the positioning detection switch 12, and therefore cannot input a drilling start signal to the control system, preventing the drilling assembly 5 from performing drilling operations. As a safety limit, such as... Figure 2 As shown, when the detection piston 15 cannot move upward, the adjusting rod 10 on the outer side of the detection piston 15 will also be unable to pass the limiting rod 11. Even if the transverse slide 301 has a tendency to drive the drilling assembly 5 to move towards the outer ring of the bearing, it will be blocked by the adjusting rod 10 and the limiting rod 11, thereby preventing the drilling assembly 5 from moving towards the outer ring of the bearing and ensuring that the outer ring of the bearing cannot be drilled when it is not properly limited.

[0043] Subsequently, if the positioning pressure plate 8 and the outer ring of the bearing are accurately positioned after adjustment, the coolant input into the outer ring of the bearing through the detection fluid hole 702 will not leak. As the coolant in the outer ring of the bearing increases, it will be input into the telescopic fluid storage assembly 14 through the fluid storage hole 802. The coolant in the telescopic fluid storage assembly 14 will continuously increase, pushing the detection piston 15 to move upward. On the one hand, the detection piston 15 compresses the spring above, and on the other hand, the detection piston 15 drives the adjusting rod 10 to move upward synchronously.

[0044] When the detection piston 15 moves to the top, the overflow groove 150 and the overflow pipe 13 are connected; the adjusting rod 10 will also be higher than the limiting rod 11; the detection piston 15 contacts the position detection switch 12, and the position detection switch 12 inputs a signal to the control system, enabling the drilling assembly 5 to perform drilling operations. The transverse reciprocating assembly 3 moves the drilling assembly 5 closer to the outer ring of the bearing through the transverse slide 301, and uses the drilling assembly 5 to perform drilling operations on the outer ring of the bearing. During this process, the coolant flowing out from the overflow pipe 13 acts on the drilling position to achieve a cooling effect during the drilling process.

[0045] After the drilling assembly 5 drills through one side of the bearing, the coolant inside the bearing flows out from the drilled hole. This reduces the amount of coolant entering the telescopic accumulator assembly 14 through the detection hole 702. The detection piston 15 moves downwards under the action of its elasticity, squeezing the telescopic accumulator assembly 14. The detection piston 15 and the overflow pipe 13 move away from each other, and the overflow pipe 13 stops discharging coolant. Then, when the drilling assembly 5 drills through the other side, the coolant inside the bearing continuously cools the drilling assembly 5. This continues until the drilling assembly 5 has completely drilled through the bearing.

[0046] Subsequently, the transverse reciprocating assembly 3 moves the polishing assembly 4 towards the outer ring of the bearing via the transverse slide 301. The polishing assembly 4 grinds and polishes the drilled hole, and the drilling assembly 5 also retracts from the outer ring of the bearing. During this process, because the detection piston 15 is pressed downward by the spring force, the coolant in the telescopic liquid storage assembly 14 and the coolant discharged from the detection liquid hole 702 flows out of the drilled hole, ensuring that the polishing assembly 4 continuously flushes the drilled hole with coolant during the grinding and polishing process, thereby improving the polishing quality. During this process, combined with Figure 2 As shown, when the transverse slide 301 drives the limiting rod 11 to retract, the limiting rod 11 can be deflected by the torsion spring. After the limiting rod 11 passes the adjusting rod 10, the limiting rod 11 is retracted into the transverse slide 301 by the deflection, ensuring that the adjusting rod 10 will not be obstructed during the process of the transverse slide 301 driving the limiting rod 11 to retract.

[0047] Finally, after the polishing component 4 has finished polishing the bearing, it moves away from the bearing, and the limiting pressure tube 7 causes the positioning pressure table 8 to release its pressure on the bearing. The robotic arm then removes the bearing. This process is repeated sequentially to achieve continuous automatic drilling and polishing of the bearing.
