Description

Technical Field

[0001] The present invention relates to the technical field of bearing processing, and particularly to a bearing cage punching device with a self-cleaning function. Background Art

[0002] A bearing is a mechanical element that restricts relative motion within the required range of motion and reduces friction between moving parts. The design of a bearing can provide free linear motion of moving parts or free rotation around a fixed axis, or prevent motion by controlling the vector of the normal force acting on the moving parts. Most bearings facilitate the required motion by minimizing friction. A bearing cage refers to a bearing part that partially wraps all or part of the rolling elements and moves with them, used to isolate the rolling elements, and usually also guides and holds the rolling elements within the bearing. Due to characteristics such as high strength, good toughness, and easy processing, steel cage materials are commonly used in rolling bearings.

[0003] During the punching process of a bearing cage, certain processing waste will be generated. Some existing bearing cage punching devices usually need to regularly clean the waste generated by the device to avoid scratches or other damages to subsequent processed parts, consuming a certain amount of manpower. And after punching, there will inevitably be more or less burrs in the window holes of the bearing cage, which requires subsequent reprocessing to clean the burrs, resulting in a reduction in the production efficiency of the device. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings that some existing bearing cage punching devices usually need to regularly clean the waste generated by the device to avoid scratches or other damages to subsequent processed parts, consuming a certain amount of manpower, and there will inevitably be more or less burrs in the window holes of the bearing cage after punching, which requires subsequent reprocessing to clean the burrs, resulting in a reduction in the production efficiency of the device, and to provide a bearing cage punching device with a self-cleaning function.

[0005] The purpose of the present invention is achieved through the following technical solutions: A bearing cage punching device with a self-cleaning function includes a platform. A bracket is installed on the platform. A clamping disc is installed on one side of the bracket. A plurality of groups of clamping claws arranged in a circumferential array are installed on the clamping disc. The clamping claws are slidably connected to the clamping disc. The plurality of groups of clamping claws are used to clamp the bearing cage workpiece. A rotatable turntable is installed on the platform. The turntable is coaxially arranged with the clamping disc; A punching machine is installed on the platform. A first motor is installed at the telescopic end of the punching machine. A punching component is installed at the power output end of the first motor. The punching component is arranged on one side of the turntable. A punching head is installed at the end of the punching component close to the turntable. A grinding wheel is installed in the middle of the punching component; A second motor is installed on one side of the bracket. A fixing column is installed at the power output end of the second motor. The clamping disc is installed at the end of the fixing column away from the second motor. Both the first motor and the second motor are servo motors.

[0006] By setting the punching machine, the punching head can be driven to punch holes in the bearing cage workpiece. When the punching machine drives the punching head to punch through the outer wall of the bearing cage workpiece, the punching machine does not drive the punching head to contract and reset first. At this time, the grinding wheel on the punching assembly is in contact with the inner wall of the window hole formed by punching the bearing cage workpiece. The first motor drives the grinding wheel to rotate to polish the inner wall of the window hole, making the inner wall of the window hole smooth and improving the processing quality. At the same time, the burrs generated on the inner wall of the window hole due to punching are effectively removed, thus effectively avoiding the subsequent re-grinding of the window hole of the bearing cage workpiece and effectively improving the production efficiency of the equipment. Setting the second motor can drive the clamping disc to rotate through the fixing column, so as to drive the bearing cage workpiece clamped on the clamping disc to rotate. Cooperating with the punching machine, the first motor and the punching assembly can realize multiple equal-angle punching and grinding of the bearing cage workpiece, thereby further improving the processing efficiency.

[0007] A further technical solution is that an electric sliding table is installed on the fixing column. The moving end of the electric sliding table is installed with a lifting block that can lift along the fixing column. Multiple groups of sliding grooves are opened on the clamping disc. Sliding blocks are slidably installed in the sliding grooves. The clamping claws are installed on the bottom surface of the sliding blocks. A connecting rod is installed between the lifting block and the sliding block. The two ends of the connecting rod are respectively rotatably connected to the lifting block and the sliding block. By setting the electric sliding table, the lifting block can be driven to lift, so as to drive the clamping claws on the sliding block to move on the clamping disc through the connecting rod, realizing the positioning and clamping of the bearing cage workpiece. The multiple groups of clamping claws are arranged in a circumferential array with respect to the clamping disc, which can realize the precise positioning of the bearing cage workpiece, making the center of the bearing cage workpiece correspond to the clamping disc, thus avoiding the angle deviation when the bearing cage workpiece rotates and punches holes, improving the processing accuracy. Setting multiple groups of clamping claws can move on the clamping disc and can meet the clamping of bearing cage workpieces with different diameters at the same time, meeting the processing requirements of the equipment for bearing cage workpieces with different sizes and improving the applicability of the equipment.

[0008] A further technical solution is that the punching assembly includes a main shaft installed at the power output end of the first motor. A threaded groove is opened at the end of the main shaft away from the first motor. An installation rod is installed at the end of the punching head close to the first motor. A threaded rod adapted to the threaded groove is installed at the end of the installation rod close to the first motor. A detachable grinding wheel is installed on the installation rod. The diameter of the grinding wheel is equal to that of the punching head. By setting the cooperation of the main shaft, the installation rod, the threaded rod and the threaded groove, the rapid disassembly and installation of the punching head and the grinding wheel can be realized, improving the efficiency of replacing the punching head and the grinding wheel.

[0009] A further technical solution is that a hydraulic cylinder is installed on one side of the bracket, and the second motor is installed at the telescopic end of the hydraulic cylinder. By setting the hydraulic cylinder, it can drive the second motor, the fixed column and the clamping plate to rise and fall for convenient material taking and placing. At the same time, it can provide a certain downward force to the bearing cage workpiece, improve the friction between the bearing cage workpiece and the turntable, ensure the stability of the bearing cage workpiece during punching, and reduce the deformation of the bearing cage workpiece.

[0010] A further technical solution is that a waste collection box corresponding to the turntable is installed at the bottom of the platform. A discharge hole corresponding to the waste collection box is opened in the middle of the turntable. A negative pressure fan is installed on one side of the waste collection box. An inclined sieve plate is installed inside the waste collection box. Multiple groups of through holes are arranged at equal distances on the sieve plate. A first discharge port corresponding to the sieve plate is opened on the side of the waste collection box. A discharge door that can be opened and closed is installed on the first discharge port. By setting the negative pressure fan, it can cooperate with the discharge hole to absorb the punching chips and debris generated by processing and polishing into the waste collection box for collection, realizing the self-cleaning function, reducing subsequent manual cleaning, effectively saving manpower. At the same time, setting the inclined sieve plate can screen the punching chips and debris generated by punching and polishing, facilitating the recycling of the punching chips.

[0011] A further technical solution is that the bottom surface of the waste collection box is arranged in an inverted conical shape. A second discharge port is installed on the bottom surface of the waste collection box. A discharge valve is installed on the second discharge port. A filter screen is installed at the air inlet end of the negative pressure fan. By setting the bottom surface of the waste collection box in an inverted conical shape and cooperating with the discharge valve on the second discharge port, it is convenient to clean the collected debris. At the same time, setting the filter screen can prevent debris from entering the negative pressure fan and damaging the negative pressure fan.

[0012] A further technical solution is that a blower is installed on the fixed column. A ventilation port corresponding to the air outlet end of the blower is opened in the middle of the clamping plate. By setting the blower and the ventilation port to cooperate to blow air into the interior of the bearing cage workpiece, and cooperating with the negative pressure fan, it can further make the punching chips and debris generated by processing pass through the discharge hole and be collected into the waste collection box, improving the self-cleaning ability of the equipment.

[0013] A further technical solution is that the turntable is installed on the platform through a slewing bearing. By setting the slewing bearing, it can ensure the stable rotation of the turntable on the platform, meeting the requirements of the turntable to bear large axial, radial loads and overturning moments.

[0014] A further technical solution is that multiple groups of clamping claws are all arc-shaped. The outer sides of multiple groups of clamping claws are all in contact with the inner ring of the bearing cage workpiece. By setting multiple groups of clamping claws to be arc-shaped, the contact area between the clamping claws and the bearing cage workpiece is increased, thereby further improving the clamping stability of the bearing cage workpiece. By setting the outer side of the clamping claw to be in contact with the inner ring of the bearing cage workpiece, a certain supporting force can be provided to the inner side of the bearing cage workpiece when the punching component punches holes, so that the stability of the bearing cage workpiece during punching is better, and the deformation generated during punching of the bearing cage workpiece is reduced.

[0015] The present invention has the following advantages: When the punching machine, the first motor and the punching component cooperate to drive the punching head to punch through the outer wall of the bearing cage workpiece, the punching machine does not drive the punching head to retract and reset first. Instead, the grinding wheel on the punching component is in contact with the inner wall of the window hole formed by punching on the bearing cage workpiece. The first motor drives the grinding wheel to rotate to polish the inner wall of the window hole, making the inner wall of the window hole smooth and improving the processing quality. At the same time, the burrs generated on the inner wall of the window hole due to punching are effectively removed, thereby effectively avoiding the subsequent re-grinding process for the window hole of the bearing cage workpiece, and effectively improving the production efficiency of the equipment.

[0023] By setting the punching machine 5, the punching head 702 can be driven to punch the bearing cage workpiece 23. When the punching machine 5 drives the punching head 702 to punch through the outer wall of the bearing cage workpiece 23, the punching machine 5 does not drive the punching head 702 to contract and reset first. At this time, the grinding wheel 703 on the punching component 7 is in contact with the inner wall of the window hole formed by punching on the bearing cage workpiece 23. The first motor 6 drives the grinding wheel 703 to rotate to polish the inner wall of the window hole, making the inner wall of the window hole smooth and improving the processing quality. At the same time, the burrs generated on the inner wall of the window hole due to punching are effectively removed, thus effectively avoiding the subsequent re-grinding of the window hole of the bearing cage workpiece 23, and effectively improving the production efficiency of the equipment; By setting the second motor 18, the clamping disc 3 can be driven to rotate through the fixed column 16, so that the bearing cage workpiece 23 clamped on the clamping disc 3 can be driven to rotate. Cooperating with the punching machine 5, the first motor 6 and the punching component 7 can realize multiple equal-angle punching and grinding of the bearing cage workpiece 23, thereby further improving the processing efficiency.

By setting the electric slide table 26, the elevating block 27 can be driven to move up and down, so that the clamping claws 4 on the slider 21 are driven by the connecting rod 22 to move on the clamping plate 3, realizing the positioning and clamping of the bearing cage workpiece 23. The plurality of groups of clamping claws 4 are arranged in a circular array with respect to the clamping plate 3, which can realize the precise positioning of the bearing cage workpiece 23, making the center of the bearing cage workpiece 23 correspond to the clamping plate 3, thus avoiding the angle deviation when the bearing cage workpiece 23 rotates and punches, improving the processing accuracy.

[0026] A hydraulic cylinder 19 is installed on one side of the bracket 2. The second motor 18 is installed at the telescopic end of the hydraulic cylinder 19. By setting the hydraulic cylinder 19, the second motor 18, the fixed column 16 and the clamping plate 3 can be driven to rise and fall to facilitate loading and unloading of materials. At the same time, a certain downward force can be provided to the bearing cage workpiece 23, increasing the friction force between the bearing cage workpiece 23 and the turntable 8, ensuring the stability of the bearing cage workpiece 23 during punching, and reducing the deformation of the bearing cage workpiece 23.

[0027] At the bottom of platform 1, a waste collection box 10 corresponding to the turntable 8 is installed.

[0029] A blower 24 is installed on the fixed column 16. A ventilation port 25 corresponding to the air outlet end of the blower 24 is opened in the middle of the clamping disc 3. By setting the blower 24 and the ventilation port 25 to cooperate to blow air into the inside of the bearing cage workpiece 23, and cooperating with the negative pressure fan 12, it further enables the punched pieces and debris generated during processing to be collected into the waste collection box 10 through the discharge hole 9, improving the self-cleaning ability of the equipment.

[0030] Multiple groups of clamping claws 4 are all arranged in an arc shape. The outer sides of multiple groups of clamping claws 4 are all in contact with the inner ring of the bearing cage workpiece 23. By setting multiple groups of clamping claws 4 in an arc shape, the contact area between the clamping claws 4 and the bearing cage workpiece 23 is increased, thereby further improving the clamping stability of the bearing cage workpiece 23. By setting the outer sides of the clamping claws 4 to be in contact with the inner ring of the bearing cage workpiece 23, a certain supporting force can be provided to the inner side of the bearing cage workpiece 23 when the punching assembly 7 punches, so that the stability of the bearing cage workpiece 23 during punching is better, and the deformation generated during punching of the bearing cage workpiece 23 is reduced.

[0031] The working process of the present invention is as follows: When using this device to punch the bearing cage workpiece 23, first place the bearing cage workpiece 23 to be punched on the turntable 8, control the hydraulic cylinder 19 to descend, and at the same time control the electric slide table 26 to drive the lifting block 27 to move, so that the lifting block 27 drives the slider 21 to move in the chute 20 through the connecting rod 22, adjust the distance between multiple groups of clamping claws 4, so that multiple groups of clamping claws 4 clamp and position the bearing cage workpiece 23 in the middle of the clamping disc 3 and the turntable 8. After clamping and positioning, the hydraulic cylinder 19 applies a certain downward pressure to the bearing cage workpiece 23 through the clamping disc 3, and then control the punching machine 5 to drive the punching head 702 on the punching assembly 7 to punch the clamping disc 3. When the punching machine 5 drives the punching head 702 to punch through the outer wall of the bearing cage workpiece 23, the punching machine 5 does not drive the punching head 702 to retract and reset first. At this time, the grinding wheel 703 on the punching assembly 7 contacts the inner wall of the window hole formed by punching on the bearing cage workpiece 23, and the first motor 6 drives the grinding wheel 703 to rotate to polish the inner wall of the window hole, completing the processing of one window hole on the bearing cage workpiece 23. At this time, the punching machine 5 drives the punching assembly 7 to reset. After the reset is completed, control the second motor 18 to drive the fixed column 16, the clamping disc 3 and the bearing cage workpiece 23 to rotate to the next set angle and punch and polish again until the processing is completed. During the punching and polishing of the bearing cage workpiece 23, the blower 24 and the negative pressure fan 12 are both turned on, and the punching chips and debris generated by punching and polishing are collected into the waste collection box 10 and screened through the sieve plate 11. Finally, the discharge door on the first discharge port 14 can be opened to recycle the punching chips in a non-stop state, and the discharge valve on the second discharge port 15 can be opened to clean the debris.
