Description

Technical Field

[0001] This utility model relates to the technical field of bearing processing, and in particular to an outer ring lifting and feeding device for processing the inner wall of the outer ring of a bearing. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Bearing manufacturing involves many complex steps, requiring forging of raw materials followed by grinding. The outer ring of the bearing is often processed individually, undergoing multiple processes such as wire shaving and grinding. Typically, manual handling is used for processing, which is inefficient, cannot meet processing demands, and is unsuitable for mass production. Existing technology publication number CN217122573U proposes a lifting and feeding device for processing bearing outer rings, including a base. A housing is fixedly connected to the top of the base. A U-shaped groove is formed on the left side of the top of the housing, and a square groove is formed on the right side of the inner cavity of the U-shaped groove. A motor is installed on the rear side of the inner cavity of the square groove. The front end of the output shaft of the motor is rotatably connected to the front side of the inner cavity of the square groove. An arc-shaped rotating block is fixedly connected to the surface of the output shaft of the motor. A rectangular surrounding plate is fixedly connected to the inner wall of the square groove. However, using a spring to lift the outer ring of the bearing makes it difficult to control the lifting height, resulting in poor operability. Furthermore, the feeding tray needs to be removed when replenishing materials, which affects usage and is not conducive to improving feeding efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an outer ring lifting and feeding device for machining the inner wall of the outer ring of a bearing, which is easy to control the lifting height, highly operable, and conducive to improving the feeding efficiency.

[0004] This utility model discloses an outer ring lifting and feeding device for machining the inner wall of a bearing outer ring. It includes a top plate, a feeding cylinder, a clamping assembly, a moving assembly, a lifting assembly, and a feeding assembly. The feeding cylinder is connected to the bottom of the top plate via the moving assembly. Two feeding chambers are opened at the front and rear ends of the feeding cylinder. A feeding port is opened at the top of the top plate. The moving assembly is installed on the top of the top plate. The lifting assembly is installed inside the feeding chamber of the feeding cylinder, and the feeding assembly is installed on the upper left side wall of the feeding cylinder. Multiple bearing outer rings can be placed in the feeding chambers. The moving assembly moves the feeding cylinder at the bottom of the top plate, aligning the two feeding chambers with the feeding port in sequence. The lifting assembly moves the bearing outer rings upward within the feeding chambers, allowing them to move through the feeding port to above the top plate. The lifting distance is controllable. The clamping assembly fixes the bearing outer rings, and the feeding assembly allows direct addition of bearing outer rings into the feeding chambers. This facilitates operation and improves work efficiency.

[0005] Preferably, the moving assembly includes two mounting slides, an electric slide rail, and an electric slider. The bottom of the top plate has symmetrically arranged mounting grooves on the left and right sides. The two mounting slides are slidably installed in the mounting grooves, with the bottom of each slide connected to the top of the feeding cylinder. An installation groove is provided at the right end of the bottom of each mounting slide, and the electric slide rail is fixed in the installation groove. The electric slider is slidably installed on the electric slide rail and connected to the right-side mounting slide. Through the cooperation of the electric slider and the electric slide rail, the mounting slides move within the mounting grooves, thereby moving the feeding cylinder at the bottom of the top plate, causing the two feeding chambers to align sequentially with the feeding ports, thus cyclically feeding the outer ring of the bearing.

[0006] Preferably, the lifting assembly includes two lifting blocks, two lifting studs, two servo motors, and two lifting studs. A lifting groove is provided in the middle of the feeding cylinder. The two lifting studs are rotatably installed on the front and rear sides of the lifting groove. The bottom input end of the lifting studs passes through the bottom of the feeding cylinder and connects to the output end of the servo motors. Both servo motors are installed at the bottom of the feeding cylinder. The two lifting blocks are screwed onto the outer wall of the lifting studs. Sliding grooves are provided at both ends of the lifting groove, communicating with the inside of the feeding chamber. The lifting blocks are slidably installed in the sliding grooves. The two lifting studs are slidably installed in the two feeding chambers, and the lifting studs are connected to the lifting blocks. Starting the servo motors drives the lifting studs to rotate, which in turn drives the lifting blocks to move upwards, causing the lifting blocks to move upwards. This allows the outer ring of the uppermost bearing to pass through the feeding port and move above the top plate. The rotation of the servo motors facilitates control of the lifting block's movement distance, making the lifting distance controllable and improving feeding accuracy.

[0007] Preferably, it also includes two guide blocks. The front and rear ends of the feeding cylinder are connected to the feeding chamber and have guide grooves. The two guide blocks are slidably installed in the guide grooves. The guide blocks are connected to the lifting block. The top of the lifting block is set to an arc shape that matches the outer ring of the bearing. When the lifting block moves, it drives the guide block to move in the guide groove, which guides and limits the lifting block to ensure stability during movement. The arc shape at the top of the lifting block can limit the outer ring of the bearing to prevent the axial outer ring at the bottom from rolling.

[0008] Preferably, the clamping assembly includes a vertical plate, a dual-output motor, two threaded rods, two moving blocks, and two clamping blocks. The vertical plate is installed on the top left end of the top plate, and extension plates are provided at both the front and rear ends of the vertical plate. The dual-output motor is installed on the left side wall of the vertical plate, and the output ends of the dual-output motor are connected to threaded rods. The threaded rods are rotatably installed on the front and rear sides of the left side wall of the vertical plate. The moving blocks are screwed onto the outer wall of the threaded rods. Clamping grooves are provided at both the front and rear ends of the vertical plate. The right end of the moving block slides through the clamping grooves and is fitted with a clamping block. The two clamping blocks are located on the front and rear sides of the feed port. After the outer ring of the bearing passes through the feed port and moves above the top plate, the dual-output motor is started to drive the threaded rods to rotate. The rotation of the threaded rods drives the moving blocks to move, so that the two clamping blocks move closer to each other and clamp the outer ring of the bearing for subsequent processing.

[0009] Preferably, the feeding assembly includes two feeding cylinders, two electric telescopic rods, and two feeding push plates. The upper left side wall of the feeding cylinder has feeding ports at both ends that are connected to the feeding chamber and match the outer ring of the bearing. The two feeding cylinders are respectively installed at the feeding ports on the left side wall of the feeding cylinder. The feeding port is located at the upper left end of the feeding cylinder. The electric telescopic rod is installed on the left side wall of the feeding cylinder, and the telescopic end of the electric telescopic rod passes through the left side wall of the feeding cylinder and is equipped with a feeding push plate. The bearing ring to be processed is added into the feeding cylinder through the feeding port. The electric telescopic rod is started to drive the feeding push plate to move, pushing the outer ring of the bearing to be processed into the feeding cylinder. The bearing ring to be processed enters the feeding chamber of the feeding cylinder through the feeding port. As feeding starts, the servo motor causes the lifting block to drive the top block to move downward, so that the bearing ring to be processed enters the feeding chamber. This helps to improve feeding efficiency and improve practicality.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: multiple bearing outer rings can be placed in the feeding chamber. The upper cylinder is moved at the bottom of the top plate by the moving component, so that the two feeding chambers are aligned with the feeding port in sequence. The bearing outer ring is moved upward in the feeding chamber by the lifting component, so that the bearing outer ring is moved to the top plate through the feeding port. The lifting distance is controllable. The bearing outer ring is fixed by the clamping component. The bearing outer ring can be directly added to the feeding chamber by the feeding component, which is convenient to operate and helps to improve work efficiency. Attached Figure Description

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] Example 1

[0020] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, symmetrical hanging grooves are provided on the left and right sides of the bottom of the top plate 1. Two hanging slides 7 are slidably installed in the hanging grooves. The bottom of the hanging slide 7 is connected to the top of the feeding cylinder 8. An installation groove is provided at the right end of the bottom of the hanging slide 7. The electric slide rail 9 is fixed in the installation groove. The electric slider 10 is slidably installed on the electric slide rail 9 and is connected to the right hanging slide 7. Two feeding chambers are provided at the front and rear ends of the feeding cylinder 8. A lifting groove is provided in the middle of the feeding cylinder 8. Two lifting studs 18 are rotatably installed on the front and rear sides of the lifting groove. The bottom input end of the lifting stud 18 passes through the bottom end of the feeding cylinder 8 and is connected to the output end of the servo motor 17. Both servo motors 17 are installed in the feeding cylinder 8. At the bottom, two lifting blocks 11 are screwed onto the outer wall of the lifting stud 18. The front and rear ends of the lifting groove are connected to the inside of the feeding chamber and have sliding grooves. The lifting blocks 11 are slidably installed in the sliding grooves. The two lifting blocks 12 are slidably installed in the two feeding chambers respectively. The lifting blocks 12 are connected to the lifting blocks 11. The front and rear ends of the upper left side wall of the feeding cylinder 8 are connected to the feeding chamber and have feeding ports that match the outer ring of the bearing. The two feeding cylinders 14 are installed at the feeding ports on the left side wall of the feeding cylinder 8 respectively. The feeding port is opened at the upper left end of the feeding cylinder 14. The electric telescopic rod 15 is installed on the left side wall of the feeding cylinder 14. The telescopic end of the electric telescopic rod 15 passes through the left side wall of the feeding cylinder 14 and is equipped with a feeding push plate 16.

[0021] The servo motor 17 is started, driving the lifting stud 18 to rotate. The lifting stud 18 drives the lifting block 11 to move upward, causing the lifting block 12 to move upward. This allows the outer ring of the uppermost bearing to pass through the feeding port and move above the top plate 1. The rotation of the servo motor 17 facilitates control over the movement distance of the lifting block 12, making the lifting distance controllable and improving feeding accuracy. Through the cooperation of the electric slider 10 and the electric slide rail 9, the hanging slide 7 is driven to move within the hanging slide groove, thereby driving the feeding cylinder 8 to move at the bottom of the top plate 1, so that the two... The feeding chamber is aligned with the feeding port in sequence to circulate the outer ring of the bearing. The bearing ring to be processed is added into the feeding cylinder 14 through the feeding port. The electric telescopic rod 15 is started to drive the feeding push plate 16 to move, pushing the outer ring of the bearing to be processed into the feeding cylinder 14. The bearing ring to be processed enters the feeding chamber of the feeding cylinder 8 through the feeding port. As the feeding is started, the servo motor 17 causes the lifting block 11 to drive the top lifting block 12 to move downward, so that the bearing ring to be processed enters the feeding chamber. This helps to improve the feeding efficiency and improves practicality.

[0022] Example 2

[0023] like Figure 2 , Figure 4 and Figure 6 As shown, based on Embodiment 1, the upper feed cylinder 8 has guide grooves at both ends connected to the feeding chamber, and two guide blocks 13 are slidably installed in the guide grooves. The guide blocks 13 are connected to the lifting block 12, and the top of the lifting block 12 is set to an arc shape that matches the outer ring of the bearing. The vertical plate 2 is installed on the top left end of the top plate 1, and extension plates are provided at both ends of the vertical plate 2. The dual-output motor 3 is installed on the left side wall of the vertical plate 2, and the output ends of the dual-output motor 3 are connected to threaded rods 4. The threaded rods 4 are rotatably installed on the front and rear sides of the left side wall of the vertical plate 2. The moving block 5 is screwed onto... On the outer wall of the threaded rod 4, clamping grooves are provided at both ends of the vertical plate 2. The right end of the moving block 5 slides through the clamping groove and is equipped with a clamping block 6. The two clamping blocks 6 are located on the front and rear sides of the feeding port. The upper left side wall of the feeding cylinder 8 is connected to the feeding chamber at both ends and is provided with a feeding port that matches the outer ring of the bearing. The two feeding cylinders 14 are respectively installed at the feeding port on the left side wall of the feeding cylinder 8. The feeding port is provided at the upper left end of the feeding cylinder 14. The electric telescopic rod 15 is installed on the left side wall of the feeding cylinder 14. The telescopic end of the electric telescopic rod 15 passes through the left side wall of the feeding cylinder 14 and is equipped with a feeding push plate 16.

[0024] When the lifting block 12 moves, it drives the guide block 13 to move within the guide groove, guiding and limiting the lifting block 12 to ensure stability during movement. The arc shape at the top of the lifting block 12 can limit the outer ring of the bearing, preventing the axial outer ring at the bottom from rolling. After the outer ring of the bearing passes through the feeding port and moves above the top plate 1, the dual-output motor 3 is started to drive the threaded rod 4 to rotate. The rotation of the threaded rod 4 drives the moving block 5 to move, so that the two clamping blocks 6 at the front and rear move closer to each other to clamp the outer ring of the bearing for subsequent processing. The bearing ring to be processed is added to the feeding cylinder 14 through the feeding port. The electric telescopic rod 15 is started to drive the feeding push plate 16 to move, pushing the outer ring of the bearing to be processed into the feeding cylinder 14. When the bearing ring to be processed enters the feeding chamber of the feeding cylinder 8 through the feeding port, the servo motor 17 is started to drive the lifting block 11 to move the lifting block 12 upward, so that the bearing ring to be processed can be moved directly through the feeding port to the top plate 1.

[0025] like Figures 1 to 6 As shown, the bearing outer ring lifting and feeding device of this utility model, when in operation, starts the servo motor 17 to drive the lifting stud 18 to rotate. The lifting stud 18 drives the lifting block 11 to move upward, causing the lifting block 12 to move upward. This allows the uppermost bearing outer ring to pass through the feeding port and move above the top plate 1. Through the cooperation of the electric slider 10 and the electric slide rail 9, the hanging slide 7 moves within the hanging slide groove, thereby driving the upper material cylinder 8 to move at the bottom of the top plate 1. This causes the two feeding chambers to align with the feeding port in sequence, cyclically feeding the bearing outer ring. The bearing outer ring passes through the feeding port and moves to the top. After the plate 1 is above, the dual-output motor 3 is started to drive the threaded rod 4 to rotate. The rotation of the threaded rod 4 drives the moving block 5 to move, so that the two clamping blocks 6 at the front and rear come closer to each other and clamp the outer ring of the bearing for subsequent processing. The bearing ring to be processed is added into the feeding cylinder 14 through the feeding port. The electric telescopic rod 15 is started to drive the feeding push plate 16 to move, pushing the outer ring of the bearing to be processed into the feeding cylinder 14. The bearing ring to be processed enters the feeding chamber of the feeding cylinder 8 through the feeding port. As the feeding is started, the servo motor 17 causes the lifting block 11 to drive the top lifting block 12 to move downward, so that the bearing ring to be processed enters the feeding chamber.

[0026] The dual-output motor 3, electric slide rail 9, electric slider 10, and servo motor 17 of the bearing outer ring inner wall machining outer ring of this utility model are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
