Description

Technical Field

[0001] This utility model relates to the field of bearing processing equipment, and in particular to an automatic chamfering and polishing machine for deep groove ball bearings. Background Technology

[0002] Deep groove ball bearings, as the most widely used type of rolling bearing, are characterized by low friction coefficient, high limiting speed, simple structure, and convenient maintenance. They are widely used in machinery manufacturing, automotive industry, aerospace, and other fields. Their machining accuracy directly affects the operational stability and service life of equipment, and chamfering is one of the key processes in bearing machining. Chamfering effectively removes burrs and sharp edges from the inner and outer rings of the bearing, preventing crack propagation caused by stress concentration during assembly, and improving the compatibility of the bearing with its mating parts.

[0003] Among existing bearing chamfering equipment, there is a deep groove ball bearing chamfering device with announcement number CN220825538U. This device uses symmetrically arranged clamping blocks on both sides to radially position the bearing, and uses an axial clamping mechanism to fix the bearing. Then, a rotating cutter is used to chamfer the edge of the bearing end face. Its structural feature is that mechanical clamping replaces manual handling, which improves processing efficiency and operational safety to a certain extent. However, its function is limited to a single chamfering process, and the clamping position needs to be adjusted multiple times during processing to accommodate different bearing specifications.

[0004] However, the aforementioned equipment has a low degree of automation, and the loading and unloading process relies on manual operation, which not only limits production efficiency but also poses positioning errors and safety hazards due to manual intervention. The chamfering and polishing processes are separated, requiring the transfer of workpieces between different devices, which adds extra handling time and costs. Utility Model Content

[0005] To overcome the shortcomings of process separation and insufficient automation, this utility model provides an integrated automatic chamfering and polishing machine for deep groove ball bearings, aiming to solve the above-mentioned shortcomings.

[0006] An automatic chamfering and polishing integrated machine for deep groove ball bearings includes a base, a chamfering machine, and a polishing machine. The chamfering machine and the polishing machine are mounted on the base. The base is equipped with a controller, which is wired to the chamfering machine and the polishing machine. It also includes a waste bin. A motor is mounted at the bottom of the base, and a turntable is rotatably connected to the top surface of the base. The output shaft of the motor is coaxially connected to the turntable. The top surface of the turntable is provided with several placement seats. The base has a chip discharge port located below the chamfering machine. The waste bin is placed below the chip discharge port. Clamping components for holding the bearings are provided in the placement seats.

[0007] As a preferred embodiment of this utility model, the clamping assembly includes a clamping plate and a pressure plate. Fixed frames are connected to the front and rear sides of the top of the placement seat. One end of the clamping plate is slidably connected to the fixed frame, and the other end passes through the placement seat and is slidably connected to it. A return spring is sleeved on one end of the clamping plate connected to the fixed frame. One end of the return spring is connected to the clamping plate, and the other end passes through the side wall of the placement seat. A guide rod is connected to the bottom of the pressure plate. The guide rod passes through the placement seat and is slidably connected to the turntable. The pressure plate passes through the placement seat and is slidably connected to the turntable. The pressure plate and the clamping plate are in a pressing fit.

[0008] As a preferred embodiment of this utility model, a top plate is connected to the top surface of the base, the top plate is slidably connected to the pressure plate, an electric push rod is installed at the bottom of the base, a contact plate is connected to the top of the piston rod of the electric push rod, and the contact plate passes through the base and the turntable and contacts the bottom of the bearing.

[0009] As a preferred embodiment of this utility model, the top surface of the base is connected to a mounting bracket, the top of the mounting bracket is equipped with an electric slide rail, the two ends of the movable plate are slidably connected to the electric slide rail, the bottom of the movable plate is equipped with a suction cup, the suction cup is connected to an external air pump, the side of the base is connected to a feeding rack, and the collection box is placed directly below the lower outlet of the feeding rack.

[0010] As a preferred embodiment of this utility model, a protective pad is laid on the inner side of the unloading rack.

[0011] As a preferred embodiment of this utility model, the end of the clamp located inside the placement seat is connected to a rubber pad.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By cooperating with the turntable and the stepper motor, the four placement seats rotate counterclockwise at a step angle of 90 degrees. Combined with the sequential control program of the controller, the bearing passes through the loading, chamfering, polishing and unloading stations in sequence, thereby realizing multi-process continuous operation, realizing automated processing, and achieving the purpose of improving processing efficiency.

[0014] 2. By cooperating with the clamping assembly and the top plate, the pressure plate presses down during loading, triggering the clamping plate to elastically hold the bearing. During unloading, the inclined surface of the top plate squeezes the pressure plate to release the clamping force. Combined with the electric push rod pushing the contact plate to lift the bearing, the suction cup adsorbs and moves along the electric slide rail to the unloading rack for automatic material handling. This achieves unmanned operation of the entire loading and unloading process, solving the problems of low efficiency, large positioning error and safety hazards caused by manual loading and unloading.

Detailed Implementation

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0023] Example: An automatic chamfering and polishing machine for deep groove ball bearings, such as... Figures 1-6As shown, the system includes a base 1, a chamfering machine 101, a polishing machine 102, and a controller 2. The chamfering machine 101 and polishing machine 102 are mounted on the base 1. The controller 2 is mounted on the base 1 and communicates with the chamfering machine 101 and polishing machine 102 via a wired connection. The controller 2 integrates a PLC control module, which can receive sensor signals in real time and adjust the equipment operating parameters to ensure the accuracy of multi-process collaborative operation. The system also includes a motor 3, a turntable 4, a placement seat 5, a waste bin 7, and a clamping assembly 8. The motor 3 is mounted at the bottom of the base 1. The machine is designed for stepping, with a single rotation angle error of less than 0.1 degrees, ensuring the accuracy of workstation switching. The top surface of the base 1 is rotatably connected to the turntable 4. The output shaft of the motor 3 is coaxially connected to the turntable 4. The top surface of the turntable 4 is provided with four placement seats 5. The inner wall of the placement seat 5 is provided with annular grooves to accommodate bearing outer rings of different outer diameters. The base 1 has one chip discharge port 6, and the turntable 4 has four chip discharge ports 6. The chip discharge ports 6 are located below the chamfering machine 101. The waste bin 7 is placed below the chip discharge ports 6. The placement seat 5 is provided with a clamping component 8 for clamping the bearing.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, the clamping assembly 8 includes a fixed frame 801, a clamping plate 802, a return spring 803, a pressure plate 804, and a guide rod 805. The fixed frame 801 is connected to the front and rear sides of the top of the placement seat 5. One end of the clamping plate 802 is slidably connected to the fixed frame 801, and the other end passes through the side wall of the placement seat 5 and is slidably connected to the placement seat 5. The end of the clamping plate 802 connected to the fixed frame 801 is fitted with the return spring 803. One end of the return spring 803 is connected to the clamping plate 802, and the other end is connected to the fixed frame 801. The bottom of the pressure plate 804 is connected to the guide rod 805. The guide rod 805 passes through the placement seat 5 and is slidably connected to the turntable 4. The pressure plate 804 passes through the placement seat 5 and is slidably connected to the turntable 4. The pressure plate 804 and the clamping plate 802 are pressed together. The bottom slope angle of the pressure plate 804 is 30 degrees, which cooperates with the slope of the clamping plate 802 to achieve efficient force transmission.

[0025] like Figure 1 , Figure 2 and Figure 5 As shown, it also includes a top plate 9, an electric push rod 10, and a contact plate 11. The top plate 9 is connected to the top surface of the base 1. The top plate 9 is slidably connected to the pressure plate 804. The top plate 9 is an arc-shaped plate, and its curvature matches the sliding path of the pressure plate 804 to avoid motion interference. An electric push rod 10 is installed at the bottom of the base 1. The top of the piston rod of the electric push rod 10 is connected to the contact plate 11. The contact plate 11 passes through the base 1 and the turntable 4 and contacts the bottom of the bearing. A polyurethane buffer layer is pasted on the surface of the contact plate 11 to avoid direct metal-to-metal collision when lifting the bearing.

[0026] like Figure 1 and Figure 6As shown, it also includes a mounting bracket 12, an electric slide rail 13, a moving plate 14, a suction cup 15, a feeding rack 16, and a collection box 17. The mounting bracket 12 is connected to the top surface of the base 1. The electric slide rail 13 is installed on the top of the mounting bracket 12. The two ends of the moving plate 14 are slidably connected to the electric slide rail 13. The suction cup 15 is installed at the bottom of the moving plate 14. The suction cup 15 is made of silicone, which is heat-resistant and has adjustable suction force. The suction cup 15 is connected to an external air pump. The feeding rack 16 is connected to the side of the base 1. The collection box 17 is placed directly below the lower outlet of the feeding rack 16. The collection box 17 is equipped with rollers for easy replacement when the box is full.

[0027] like Figure 1 and Figure 6 As shown, it also includes a protective pad 18. The inner side of the unloading rack 16 is covered with a protective pad 18, which is made of EPDM rubber and effectively buffers the impact of the bearing falling.

[0028] like Figure 4 As shown, it also includes a rubber pad 19. One end of the clamping plate 802 located in the placement seat 5 is connected to the rubber pad 19. The rubber pad 19 is made of nitrile rubber, which ensures clamping force and avoids damaging the bearing.

[0029] The four placement seats 5 are distributed in a cycle according to the process, and complete the loading-chamfering-polishing-unloading process in sequence. The turntable 4 is driven by the stepper motor 3 to rotate counterclockwise at a step angle of 90 degrees. The controller 2 coordinates the action sequence of each electrical component through a preset program to ensure the automatic connection of the whole process.

[0030] During loading, the worker manually and steadily places the bearing in the placement seat 5, and then presses down the pressure plate 804. The pressure plate 804 slides vertically down along the guide rod 805, and its bottom inclined surface contacts and squeezes the end inclined surface of the clamping plate 802, pushing the clamping plate 802 to slide horizontally along the fixed frame 801. The end of the clamping plate 802 gradually approaches the outer ring of the bearing, and the rubber pad 19 contacts the outer edge of the bearing and undergoes elastic compression, forming a flexible clamping force. During this process, the return spring 803 is stretched and stored by the clamping plate 802, and the guide rod 805 slides in the pre-set guide hole of the turntable 4 to ensure that the pressure plate 804 moves vertically. Finally, the plane of the pressure plate 804 fits with the plane of the clamping plate 802, completing the precise positioning and fixing of the bearing and preventing the bearing from rotating with the turntable 4 during processing.

[0031] During chamfering, stepper motor 3 drives turntable 4 to rotate 90 degrees counterclockwise and then stops precisely. The center of the current placement seat 5 is aligned with the drill bit of chamfering machine 101. Chamfering machine 101 drives the drill bit to move vertically downward. After the drill bit end contacts the edge of the bearing, it rotates at high speed and completes the chamfering process through progressive cutting. After reaching the preset depth, the drill bit resets. The metal chips generated during processing fall naturally from the chip discharge port 6, which is aligned with the base 1 on turntable 4, and collect in the waste bin 7.

[0032] During polishing, the stepper motor 3 drives the turntable 4 to rotate 90 degrees counterclockwise again and then stops. The center of the current placement seat 5 is aligned with the grinding wheel of the polishing machine 102. The polishing machine 102 drives the grinding wheel to move vertically downward. The surface of the grinding wheel makes uniform contact with the chamfered area of ​​the bearing. The surface burrs are removed by low-speed rotation polishing. After the preset polishing time is reached, the grinding wheel is reset and the turntable 4 remains stationary and waits for the material to be unloaded.

[0033] During unloading, the stepper motor 3 drives the turntable 4 to continue rotating. The end of the pressure plate 804 is in contact with the bottom inclined surface of the top plate 9. The inclined surface of the top plate 9 presses the pressure plate 804 upward, causing it to slide upward. The pressure plate 804 disengages from the clamping plate 802. The return spring 803 releases its stored energy, pulling the clamping plate 802 horizontally back. The rubber pad 19 separates from the outer edge of the bearing, releasing the clamp. During this process, the electric push rod 10 simultaneously pushes the contact plate 11 vertically upward. After the contact plate 11 passes through the gap between the turntable 4 and the base 1, it lifts the bearing, and the top of the bearing... When the suction cup 15 at the bottom of the moving plate 14 contacts the bearing, the air pump starts to draw air out of the suction cup 15 to form a negative pressure. After the suction cup 15 adsorbs the bearing, the electric slide rail 13 drives the moving plate 14 to move horizontally above the unloading rack 16. The air pump releases the positive pressure to make the bearing detach from the suction cup 15. The bearing falls onto the protective pad 18 of the unloading rack 16 and slides down the slope into the collection box 17. Then the electric push rod 10 pulls the contact plate 11 in the opposite direction to move it vertically downward to reset it, so as not to affect the subsequent rotation of the turntable 4. The turntable 4 continues to rotate to the initial position and enters the next cycle.

[0034] The entire process is monitored in real time by controller 2 to ensure the precise sequence of actions. The elastic buffer of protective pad 18 prevents collision damage when the bearing is unloaded, realizing continuous automated processing of deep groove ball bearing chamfering and polishing. During equipment operation, the accumulation of debris in waste bin 7 needs to be checked regularly and emptied in time; at the same time, the loading status of collection bin 17 should be observed and full collection bin 17 should be replaced in time to ensure continuous production.

[0035] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
