Description

Technical Field

[0001] This utility model relates to the field of multi-angle, multi-station drilling of bearing rings, and more specifically, to a multi-angle, multi-station drilling device for bearing rings. Background Technology

[0002] Bearing rings are annular components of radial rolling bearings with one or more raceways, and are an important part of the bearing. Bearing rings consist of an inner ring and an outer ring, with the outer ring typically being drilled. However, during the drilling process, it is necessary to ensure accurate drilling of the bearing ring's height or depth angle; therefore, a multi-angle, multi-station drilling device needs to be designed.

[0003] For example, Chinese patent CN221890918U discloses a bearing ring drilling device, including a processing table and a placement table. Two support legs are symmetrically installed at the bottom of the processing table, and an adjustment mechanism is provided inside the processing table. A limiting mechanism is provided on the placement table. Although this device can clamp and fix the bearing ring and drill holes, it can only perform a single drilling operation at a fixed angle, limiting its drilling functionality. Furthermore, it cannot adjust the drilling depth, resulting in poor product manufacturing quality.

[0004] Most existing drilling mechanisms have a limited range of drilling depths for bearing races, making it difficult to flexibly adjust the drilling height (referring to the position of the drill bit) and depth. Furthermore, they have a low level of automation, and most can only process one bearing race at a time, leading to increased labor intensity for operators and reduced production efficiency.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In response to the problems in related technologies, this utility model proposes a multi-angle, multi-station drilling device for bearing rings to overcome the aforementioned technical problems existing in the prior art.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A multi-angle, multi-station drilling device for bearing rings includes a worktable. A support frame is installed at the top of one end of the worktable. A vertical moving component is inserted through the middle of the support frame. A slider is installed through the vertical moving component. A mounting groove is opened at one end of the slider. A lateral moving drilling mechanism is installed inside the mounting groove. A rotating component is installed at the top of the end of the worktable away from the support frame. A circumferentially symmetrical clamping mechanism is installed at the top of the rotating component. A protective component that cooperates with the clamping mechanism is installed at the bottom of the rotating component.

[0009] Furthermore, in order to adjust the height of the lateral moving drilling mechanism, the vertical moving component includes a first threaded rod inserted through the middle of the support frame, and first limiting rods on both sides of the first threaded rod; the top of the first threaded rod passes through the support frame and is connected to a first adjusting motor; the first threaded rod and the first limiting rod cooperate with the slider.

[0010] Furthermore, in order to enable the drilling position to be quickly and accurately located, reducing positioning time and errors, the lateral moving drilling mechanism includes a second threaded rod disposed on both sides inside the mounting groove, with a second limiting rod disposed on both sides of the second threaded rod; a convex slider is disposed through the second threaded rod and the second limiting rod, and a drilling motor is disposed on one side of the top of the convex slider; the output shaft of the drilling motor passes through the convex slider and is connected to a spiral clamping post; a spiral clamping post is engaged inside the spiral clamping post, and a drilling head is disposed at one end of the spiral clamping post near the clamping mechanism; a second adjusting motor is connected to one side of the second threaded rod passing through the mounting groove.

[0011] Furthermore, in order to adjust the angle of the clamping mechanism, the rotating assembly includes a variable speed motor mounted on the top of the worktable, a variable speed shaft connected to the top of the variable speed motor, a bearing sleeved on the top of the variable speed shaft, and a first fixing post mounted on the outside of the bearing; a circular mounting plate is mounted on the bottom of the variable speed shaft.

[0012] Furthermore, to prevent displacement or deformation during drilling and to achieve stable clamping across multiple positions, ensuring drilling accuracy and consistency, the clamping mechanism includes several circumferentially arranged drive shafts mounted on the top of a circular mounting plate. A circular plate is positioned on top of the drive shafts, and a circular chuck is positioned at the bottom of the circular plate. Several second fixing posts are positioned on the outer circumference of the circular chuck, and clamping blocks are mounted on the second fixing posts. Each clamping block has several anti-slip protrusions. The circular plate has movable grooves that mate with the clamping blocks. A motor is connected to the bottom of the drive shafts, and a positive and negative ring are respectively positioned at the bottom of the motor. Positive and negative power receiving hooks are respectively fixedly connected to the positive and negative power receiving hooks. A power receiving rod is positioned at the bottom of each positive and negative power receiving hook, and a tension spring is positioned at the bottom of the power receiving rod. A circular chuck is positioned at the bottom of the tension spring. A clamping post is positioned in the center of the top of the circular chuck. A clamping block is positioned at one end of each of the second fixing posts, and the clamping block mates with the clamping block. The workbench is equipped with negative and positive electrode contact rails that mate with the positive and negative electrode contact hooks, and both rails have grooves inside that mate with a circular chuck. Anti-slip protrusions are arranged linearly from top to bottom, with adjacent protrusions having different lengths. The movement trajectory of the clamping block matches the curvature of the movable groove; several second fixing posts form a cross-shaped symmetrical structure on the outer circumference of the circular housing.

[0013] Furthermore, in order to protect the power connection of the clamping mechanism, the protective component includes an outer baffle symmetrically arranged at the bottom of the circular mounting plate, an inner baffle that cooperates with the motor is arranged inside the outer baffle, and the circular mounting plate and the outer baffle are fixedly connected by bolts.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. After multiple bearing rings are placed on multiple workstations and tightened, the drilling position and depth are adjusted, and drilling devices are used to drill holes in the bearing rings. Equipped with a vertical moving component, a horizontal moving drilling mechanism, a rotating component, a clamping mechanism, and protective measures, the multiple clamping mechanisms firmly hold the bearing rings, preventing displacement or deformation during drilling. This achieves stable clamping across multiple workstations, ensuring drilling accuracy and consistency. Through the rotation function of the rotating component, the horizontal moving drilling mechanism can perform drilling operations at different angles, meeting the multi-angle drilling requirements of the bearing rings. After the rotating component and clamping mechanism are adjusted to the correct angles and clamped in place, the vertical moving component is adjusted to the correct height, and the horizontal moving drilling mechanism can precisely control and achieve the drilling depth of the bearing race at different workstations. Simultaneously, depending on the type of drilling, the corresponding drilling head can be replaced, which greatly improves production efficiency and allows the equipment to adapt to various drilling needs. The precise coordination between the vertical moving component and the horizontal moving drilling mechanism enables the drilling position to be quickly and accurately located, effectively reducing positioning time and errors. Furthermore, the protective components ensure the electrical output and protect the motor of the clamping mechanism during operation.

[0016] 2. Through the vertical moving component and the horizontal moving drilling mechanism, when the first adjusting motor is started, its output shaft drives the first threaded rod to rotate. The first threaded rod, through threaded engagement with the slider and support frame, converts the rotation of the first threaded rod into linear motion, thereby adjusting the height of the horizontal moving drilling mechanism. Simultaneously, the first limiting rod limits the movement range of the vertical moving component, ensuring it does not exceed the predetermined working area and providing accurate positioning for the drilling operation. Furthermore, the second adjusting motor of the horizontal moving drilling mechanism drives the second threaded rod to rotate, and the convex slider engages with the second threaded rod through threaded engagement. The rotation of the second threaded rod is converted into the linear motion of the convex slider, enabling the lateral moving drilling mechanism to move horizontally to adjust the drilling position. The second limit rod is used to limit the range of motion of the convex slider, ensuring that the lateral moving drilling mechanism does not exceed the predetermined working area during drilling. During the drilling process, the output shaft of the drilling motor drives the drilling head to rotate and drill. The design of the spiral groove post and the spiral clamping post makes it easy to replace the type of drilling head. With the cooperation of the vertical moving component and the lateral moving drilling mechanism, the shaking and deviation during the drilling process can be reduced.

[0017] 3. Equipped with a rotating component and a clamping mechanism, when the variable speed motor starts, it drives the circular mounting plate at the top of the variable speed shaft to rotate, while the bearing inside the first fixed column at the top of the circular mounting plate remains relatively stationary. The circular mounting plate drives multiple clamping mechanisms to rotate, thereby adjusting the angle of the bearing ring workpiece. Before drilling or rotating operations, the bearing ring needs to be clamped. When the negative and positive electrical rails of the worktable are energized, the negative and positive electrical rails are connected via the positive ring at the bottom of the motor. The negative electrode ring transmits power to the receiving pole, which then supplies power to the positive and negative electrode hooks. A tension spring on the outside of the receiving pole provides shock absorption and length adjustment. A circular chuck at the bottom of the tension spring engages with the slots on the negative and positive electrode contact rails, limiting rotation and preventing detachment and loss of power. Power is supplied to the motor, causing the drive shaft to rotate and clamp the holding block on the second fixed column towards the center. The movement trajectory is within the movable slot. During movement, the clamping block prevents the holding block from falling off, improving clamping efficiency and overall work efficiency. Attached Figure Description

[0028] According to an embodiment of the present invention, a multi-angle, multi-station drilling device for bearing rings is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the bearing ring multi-angle multi-station drilling device according to an embodiment of the present invention includes a worktable 1, a support frame 2 is provided at the top of one end of the worktable 1, a vertical moving component 3 is inserted through the middle of the support frame 2, a slider 4 is provided through the vertical moving component 3, an installation groove 5 is provided at one end of the slider 4, and a transverse moving drilling mechanism 6 is provided inside the installation groove 5; a rotating component 7 is provided at the top of the end of the worktable 1 away from the support frame 2, a circumferentially symmetrical clamping mechanism 8 is provided at the top of the rotating component 7; and a protective component 9 is provided at the bottom of the rotating component 7 to cooperate with the clamping mechanism 8.

[0030] Furthermore, in practical applications, a control panel is provided on the outside of the worktable 1, and the control panel is electrically connected in sequence to the vertical moving component 3, the horizontal moving drilling mechanism 6, the rotating component 7, and the clamping mechanism 8. The aforementioned control panel is prior art and is not shown in the figure; therefore, it will not be described in detail here.

[0031] With the help of the above-mentioned technical solution of this utility model, after multiple bearing rings are placed on multiple workstations and tightened, the position and depth of the drilling are adjusted, and the drilling device is used to drill holes in the bearing rings. By providing a vertical moving component 3, a horizontal moving drilling mechanism 6, a rotating component 7, and a clamping mechanism 8, the multiple clamping mechanisms 8 firmly clamp the bearing rings, preventing displacement or deformation during drilling, achieving stable clamping at multiple workstations, and ensuring the accuracy and consistency of drilling. Through the rotation function of the rotating component 7, the horizontal moving drilling mechanism 6 can perform drilling operations at different angles, meeting the requirements of the bearing rings for drilling at multiple angles. The drilling requirements are met; after the rotating component 7 and the clamping mechanism 8 are adjusted to the correct angle and clamped in place, the vertical moving component 3 is adjusted to the correct height, and the horizontal moving drilling mechanism 6 can precisely control and achieve the drilling depth of the bearing ring at different work positions; at the same time, the corresponding drilling head can be changed according to the different drilling types, which greatly improves production efficiency and enables the equipment to adapt to various drilling requirements; the precise cooperation between the vertical moving component 3 and the horizontal moving drilling mechanism 6 enables the drilling position to be quickly and accurately positioned, effectively reducing positioning time and errors, and the protective component 9 can ensure the power output and protect the motor of the clamping mechanism during operation.

[0032] In one embodiment, the vertical moving component 3 includes a first threaded rod 301 inserted through the middle of the support frame 2, and first limiting rods 302 on both sides of the first threaded rod 301; the top of the first threaded rod 301 passes through the support frame 2 and is connected to a first adjusting motor 303; the first threaded rod 301 and the first limiting rods 302 cooperate with the slider 4 to adjust the height of the horizontal moving drilling mechanism 6.

[0033] In one embodiment, the lateral moving drilling mechanism 6 includes a second threaded rod 601 disposed on both sides inside the mounting groove 5, and a second limiting rod 602 disposed on both sides of the second threaded rod 601; a convex slider 603 is disposed through the second threaded rod 601 and the second limiting rod 602, and a drilling motor 604 is disposed on one side of the top of the convex slider 603. The output shaft of the drilling motor 604 passes through the convex slider 603 and is connected to a spiral retaining post 605. A spiral retaining post 606 is engaged inside the spiral retaining post 605, and a drilling head 607 is disposed at one end of the spiral retaining post 606 near the clamping mechanism 8; a second adjusting motor 608 is connected to one side of the second threaded rod 601 that passes through the mounting groove 5, thereby enabling the drilling position to be quickly and accurately positioned, reducing positioning time and error.

[0034] The working principle of the vertical moving component 3 and the horizontal moving drilling mechanism 6 is as follows: When the first adjusting motor 303 starts, its output shaft drives the first threaded rod 301 to rotate. The first threaded rod 301, through threaded engagement with the slider 4 and the support frame 2, converts the rotation of the first threaded rod 301 into linear motion, adjusting the height of the horizontal moving drilling mechanism 6. The first limiting rod 302 is used to limit the movement range of the slider 4, and the second adjusting motor 608 of the horizontal moving drilling mechanism 6 drives the second threaded rod 601 to rotate. The convex slider 603 and the second threaded rod 601 are connected by a threaded engagement. The rotation of the second threaded rod 601 is converted into the linear motion of the convex slider 603, allowing the output end of the drill head 607 to move horizontally. The second limiting rod 602 is used to limit the range of motion of the convex slider 603, ensuring that the output end of the drill head 607 does not exceed the predetermined working area during drilling. During the drilling process, the output shaft of the drilling motor 604 drives the drill head 607 to rotate and drill. The engagement of the spiral groove post 605 and the spiral snap post 606 makes it easy to replace the type of drill head 607 and fix the drill head 607.

[0035] In one embodiment, the rotating assembly 7 includes a variable speed motor 701 disposed on the top of the worktable 1, a variable speed shaft 702 connected to the top of the variable speed motor 701, a bearing 703 sleeved on the top of the variable speed shaft 702, and a first fixing post 704 disposed on the outside of the bearing 703; a circular mounting plate 705 is disposed at the bottom of the variable speed shaft 702, thereby adjusting the angle of the clamping mechanism 8.

[0036] In one embodiment, the clamping mechanism 8 includes several circumferentially arranged drive shafts 801 disposed on the top of the circular mounting plate 705. A circular plate 802 is disposed on the top of the drive shafts 801, and a circular retainer 803 is disposed at the bottom of the circular plate 802. Several second fixing posts 804 are disposed on the outer circumference of the circular retainer 803, and clamping blocks 805 are disposed on the second fixing posts 804. Several anti-slip protrusions 806 are disposed on the clamping blocks 805. The circular plate 802 has openings that cooperate with the clamping blocks 805. The movable groove 807; the bottom end of the drive shaft 801 is connected to a motor 808, and the bottom of the motor 808 is respectively provided with a positive ring 816 and a negative ring 817; the positive ring 816 and the negative ring 817 are respectively fixedly connected to a positive power receiving hook 809 and a negative power receiving hook 810, and the bottom of the positive power receiving hook 809 and the negative power receiving hook 810 is provided with a power receiving rod 811, the bottom of the power receiving rod 811 is provided with a tension spring 812, and the bottom of the tension spring 812 is provided with a circular chuck 813; and the top center of the circular chuck 803 is provided with a locking post 814. One end of the second fixing post 804 is provided with a locking block 815, which cooperates with the clamping block 805. The workbench 1 is provided with a negative electrode contact slide rail 101 and a positive electrode contact slide rail 102 that cooperate with the positive electrode contact hook 809 and the negative electrode contact hook 810. Both the negative electrode contact slide rail 101 and the positive electrode contact slide rail 102 have slots 103 inside that cooperate with the annular chuck 813. Anti-slip protrusions 806 are arranged linearly from top to bottom, and the lengths of adjacent anti-slip protrusions 806 are different. The movement trajectory of the clamping block 805 is the same as the curvature of the movable groove 807; several second fixing posts 804 are arranged in a cross-shaped symmetrical structure on the outer circumference of the circular housing 803. The protective component 9 includes an outer baffle 901 symmetrically disposed at the bottom of the circular mounting plate 705, and an inner baffle 902 that cooperates with the motor 808 is disposed inside the outer baffle 901; the circular mounting plate 705 and the outer baffle 901 are fixedly connected by bolts to prevent displacement or deformation during drilling, realize stable clamping in multiple positions, and ensure the accuracy and consistency of drilling.

[0037] Working principle of rotating component 7 and clamping mechanism 8: The bearing ring needs to be clamped. The bearing ring is placed on the clamping post 814 in the middle of the circular plate 802. When the negative and positive power-connected slide rails 101 and 102 of the worktable 1 are energized, the negative and positive power-connected slide rails 101 and 102 are energized via the bottom of the motor 808 and the power-receiving rod 811 to the positive and negative power-receiving hooks 809 and 810. The tension spring 812 on the outside of the power-receiving rod 811 is adjusted for shock absorption, and the circular chuck 813 at the bottom of the tension spring 812 engages with the slot 103 of the negative and positive power-connected slide rails 101 and 102, limiting rotation and preventing it from falling off and becoming energized. The motor 808 is energized, causing the drive shaft 801 to rotate and drive the second fixed post 804. The clamping block 805 clamps the bearing ring towards the center, and the circular clasp 803 is fixed on the drive shaft 801. The clamping block 805 moves within the movable groove 807. During movement, the clasp 815 prevents the clamping block 805 from falling off and clamps the bearing ring. The anti-slip protrusion 806 on the clamping block 805 can prevent slippage when clamping the bearing ring, and the clasp 815 blocks the clamping block 805 to prevent it from falling off. When the speed change motor 701 starts, it drives the circular mounting plate 705 on the top of the speed change shaft 702 to rotate. The bearing 703 inside the first fixed post 704 on the top of the circular mounting plate 705 remains relatively stationary. The outer ring of the bearing is fixed to the first fixed post 704, and the inner ring rotates together with the speed change shaft 702. The circular mounting plate 705 drives multiple clamping mechanisms 8 to rotate.

[0038] Meanwhile, when the power output is controlled by the control panel, the process is transmitted through electrical connection between the negative terminal connecting slide rail 101, positive terminal connecting slide rail 102, slot 103, motor 808, positive ring 816, negative ring 817, positive terminal receiving hook 809, negative terminal receiving hook 810, receiving rod 811, tension spring 812 and circular chuck 813 on the workbench 1. The working principle of the negative terminal connecting slide rail 101, positive terminal connecting slide rail 102, motor 808, positive terminal receiving hook 809, negative terminal receiving hook 810 and receiving rod 811 is the working principle of pantograph, which is existing technology and will not be described in detail here.

[0039] Furthermore, the contact surfaces of the aforementioned negative electrode contact slide rail 101 and positive electrode contact slide rail 102 with the circular chuck 813 are carbon plate structures made of semi-reinforcing carbon black, -398 flake graphite, 599 flake graphite, charcoal powder, and molten coal tar pitch, which give them unique wear resistance and self-lubricating properties when supplying power; and they have low resistivity, low bonding resistance, strong spark suppression ability, and excellent current carrying capacity.

[0040] In one embodiment, the protective component 9 includes an outer baffle 901 symmetrically disposed at the bottom of the circular mounting plate 705, and an inner baffle 902 that cooperates with the motor 808 is disposed inside the outer baffle 901. The circular mounting plate 705 and the outer baffle 901 are fixedly connected by bolts, thereby protecting the power connection of the clamping mechanism.

[0041] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0042] In practical applications, when multiple bearing rings are placed on the clamping post 814 in the middle of the placement circular plate 802 on the clamping mechanism 8, and when the negative terminal energized slide rail 101 and the positive terminal energized slide rail 102 are energized through the positive terminal ring 816 and negative terminal ring 817 at the bottom of the motor 808 to the power receiving rod 811 to energize the positive terminal power receiving hook 809 and the negative terminal power receiving hook 810, the drive shaft 801 is driven to rotate, causing the clamping block 805 on the second fixed post 804 to clamp towards the middle, thus clamping and fixing multiple bearing rings. Then, the variable speed motor 701 of the rotating assembly 7 drives the circular mounting plate 705 at the top of the variable speed shaft 702 to rotate, and drives the entire clamping mechanism 8 to rotate and adjust its position (the working principle of the rotating assembly 7 and the clamping mechanism 8 is as described above). After clamping, fixing and rotation adjustment are completed, the bearing rings are then... The first adjusting motor 303 of the vertical moving component 3 drives the first threaded rod 301 to drive the slider 4 to move vertically in a straight line. The first limiting rod 302 is used to limit the range of motion of the slider 4. Then, the drilling height is adjusted. Then, the second adjusting motor 608 of the horizontal moving drilling mechanism 6 drives the second threaded rod 601 to move horizontally in a straight line. The second limiting rod 602 is used to limit the range of motion of the convex slider 603. After the type of drilling head 607 is selected, it is installed on the spiral groove post 605 and the spiral clamping post 606 and fixed. Then, the output shaft of the drilling motor 604 drives the drilling head 607 at one end of the spiral clamping post 606 to rotate and drill (the working principle of the vertical moving component 3 and the horizontal moving drilling mechanism 6 is as described above).
