Description

Technical Field

[0001] This invention relates to the field of bearing manufacturing technology, and more specifically, to an intelligent machining platform suitable for bearing production. Background Technology

[0002] Bearings are important components in mechanical equipment. Their main function is to support rotating parts of the machine, reduce the coefficient of friction during movement, and ensure rotational accuracy. Bearings can be divided into two main categories: rolling bearings and sliding bearings.

[0003] In the prior art, Chinese patent application number 202322065161.6 discloses a grinding device for bearing production and processing, relating to the field of bearing processing equipment. The grinding device for bearing production and processing includes a grinding table and a grinding assembly. The grinding assembly is installed on the grinding table, and the device also includes a mounting plate, a first clamping device, and a second clamping device. The bottom of the mounting plate is fixedly connected to the top of the grinding table, and a movable shell is movably connected to the mounting plate. The first clamping device is connected to the movable shell, and multiple evenly distributed movable plates for pressing the inner wall of the bearing ring are movably connected to the first clamping device. The movable plates are movably inserted into through holes of appropriate size opened in the bottom wall of the inner cavity of the movable shell. The second clamping device is installed at one end of the movable plate. The grinding device for bearing production and processing provided by this utility model can clamp the inner wall and side wall of the bearing ring respectively through the first clamping device and the second clamping device, thereby improving the clamping effect.

[0004] However, the above-mentioned technical solutions can only clamp the inner ring of the bearing, thus only the outer ring of the bearing can be ground. During the processing of the bearing ring, both the inner and outer rings need to be ground, but the inner ring of the bearing ring cannot be ground. Grinding the inner ring requires special inner ring grinding equipment, which increases processing costs and is inefficient. Secondly, metal dust is generated during the grinding of the bearing ring, and there is no structure to collect and treat the grinding dust, which will pollute the working environment and has poor environmental protection. Therefore, this application proposes an intelligent processing platform suitable for bearing production to solve the above problems. Summary of the Invention

[0005] The purpose of this application is to provide an intelligent processing platform suitable for bearing production, in order to solve the problems mentioned in the background art, which can only clamp the inner ring of the bearing and therefore can only grind the outer ring of the bearing. When processing the bearing ring, both the inner and outer rings need to be ground, but it cannot grind the inner ring of the bearing ring. Grinding the inner ring requires special inner ring grinding equipment, which increases processing costs and is inefficient. Secondly, when grinding the bearing ring, metal dust is generated, and there is no structure for collecting and treating the grinding dust, which pollutes the working environment and has poor environmental protection.

[0006] To achieve the above objectives, this application provides the following technical solution: an intelligent machining platform suitable for bearing production, including a machining table, the machining platform further comprising: An external clamping mechanism includes: a first turntable, four second electric push rods and four first clamping plates. The first turntable is located above the processing table. The four second electric push rods are all fixedly installed on the left side of the first turntable. One side of the first clamping plate is fixedly installed on the output shaft of the corresponding second electric push rod. An internal clamping mechanism includes: a second turntable, four sixth electric push rods and four second clamping plates. The second turntable is located on the top of the processing table. The four sixth electric push rods are all fixedly installed on the right side of the second turntable. The second clamping plates are fixedly installed on the output shafts of the corresponding sixth electric push rods. A drive mechanism is provided on the top of the processing table, and the drive mechanism cooperates with the first turntable and the second turntable respectively; A bracket, which is fixedly installed on the top of the processing table; A grinding mechanism is provided at the bottom of the support frame, and the grinding mechanism cooperates with both an external clamping mechanism and an internal clamping mechanism. A dust removal mechanism is installed on the front side of the support and is used to collect and process grinding dust. With the above structure, by setting an external clamping mechanism, four second electric push rods are activated to push four first clamping plates to clamp from the outside of the bearing outer ring. By setting an internal clamping mechanism, four sixth electric push rods are activated to push the second clamping plates to clamp from the inside of the bearing inner ring. The two clamping methods are integrated on the same platform. The drive mechanism drives the first turntable and the second turntable to rotate so that the bearing outer ring or inner ring faces the grinding mechanism. The grinding mechanism processes the surface of the outer ring or inner ring as needed. One device has both outer ring clamping and inner ring clamping functions. There is no need to transfer the bearing ring to a dedicated inner ring grinding device, which reduces equipment investment costs and transfer time. It also solves the problems of existing platforms that can only clamp the outer ring and cannot grind the inner ring and lack a dust removal structure.

[0007] Preferably, the left side of the first turntable has four first sliding grooves, which are arranged in a ring at equal intervals. The right end of the first clamping plate is slidably connected to the inside of the corresponding first sliding groove. The right side of the second turntable has four second sliding grooves, which are arranged in a ring at equal intervals. The left end of the second clamping plate is slidably connected to the inside of the corresponding second sliding groove. By having four first sliding grooves on the left side of the first turntable and evenly distributed in a ring, and the right end of the first clamping plate slidably connected to the corresponding first sliding groove, and four second sliding grooves on the right side of the second turntable and evenly distributed in a ring, and the left end of the second clamping plate slidably connected to the corresponding second sliding groove, the sliding grooves provide precise radial guidance for the clamping plates, ensuring that the four first clamping plates or four second clamping plates move synchronously radially under the drive of the electric push rod. This makes the clamping force evenly distributed on the circumference of the bearing ring, avoiding deformation of the bearing ring or unstable clamping due to the skew of the clamping plates. The limiting effect of the sliding grooves also prevents the clamping plates from deflecting during the clamping process, improving the centering accuracy and repeatability of the clamping, and ensuring that the bearing ring maintains a stable position during rotational grinding.

[0008] Preferably, a first baffle is fixedly installed on one side of the first clamping plate, a fourth electric push rod is fixedly installed on one side of the first clamping plate, and a first limiting plate is fixedly installed on the output shaft of the fourth electric push rod. The first limiting plate cooperates with the first baffle. A second baffle is fixedly installed on one side of the second clamping plate, and a seventh electric push rod is fixedly installed on one side of the second clamping plate. A second limiting plate is fixedly installed on the output shaft of the seventh electric push rod. The second limiting plate cooperates with the second baffle. By fixing the first baffle and the fourth electric push rod on one side of the first clamping plate, the fourth electric push rod pushes the first... The limiting plate moves towards the first baffle to clamp the end face of the bearing ring. The second baffle and the seventh electric push rod are fixed on one side of the second clamping plate. The seventh electric push rod pushes the second limiting plate towards the second baffle to clamp the end face of the bearing ring. The cooperation between the baffle and the limiting plate provides positioning and clamping force in the axial direction of the bearing ring, preventing the bearing ring from moving axially or falling off during the rotary grinding process. The travel of the limiting plate is adjustable to accommodate bearing rings of different thicknesses. The combination of axial clamping and radial clamping ensures that the bearing ring is constrained in multiple directions during grinding, making the fixation more secure and reliable.

[0009] Preferably, a first anti-slip pad is fixedly installed on one side of each of the four first clamping plates, and a second anti-slip pad is fixedly installed on one side of each of the four second clamping plates. By fixing the first anti-slip pad to one side of each of the four first clamping plates and the second anti-slip pad to one side of each of the four second clamping plates, the anti-slip pads are made of elastic material with a high coefficient of friction. When clamped, they directly contact the surface of the bearing ring, increasing the friction between the clamping plates and the bearing ring and preventing circumferential slippage of the bearing ring during rotation and grinding. The elastic material avoids the hard clamping plates from directly pressing on the surface of the bearing ring, causing indentations or damage. It is especially suitable for the surface protection of bearing rings that have been processed or heat-treated. The deformation of the anti-slip pads can also compensate for the processing deviation of the outer or inner diameter of the bearing ring, so that the clamping force is evenly distributed. After disassembly, there are no clamping marks on the surface of the bearing ring, ensuring the appearance quality of the finished product and the subsequent assembly accuracy.

[0010] Preferably, a connecting frame is fixedly installed on the output shaft of the sixth electric push rod. One end of the connecting frame is fixedly installed on both sides of the corresponding second clamping plate. By fixing the connecting frame on the output shaft of the sixth electric push rod and fixing one end of the connecting frame on both sides of the corresponding second clamping plate, the connecting frame facilitates the connection between the sixth electric push rod and the second clamping plate and will not cause installation conflict with the seventh electric push rod.

[0011] Preferably, the driving mechanism includes a first electric push rod, a first movable frame, a first motor, a fifth electric push rod, a second movable frame, and a second motor. The first and fifth electric push rods are both fixedly mounted on the top of the processing table. The output shaft of the first electric push rod is fixedly mounted on one side of the first movable frame, the first motor is fixedly mounted on one side of the first movable frame, and the output shaft of the first motor is fixedly mounted on the right side of the first turntable. The output shaft of the fifth electric push rod is fixedly mounted on one side of the second movable frame, the second motor is fixedly mounted on one side of the second movable frame, and the output shaft of the second motor is fixedly mounted on the left side of the second turntable. Activating the first electric push rod drives the first movable frame, the first motor, and the first turntable to move laterally, facilitating the movement of the external clamping mechanism and the bearing ring towards the grinding mechanism and dust removal mechanism, thus facilitating the grinding of the inner ring of the bearing ring. The first motor drives... The first turntable rotates, causing the bearing ring to rotate, facilitating the grinding of the inner ring. The fifth electric push rod pushes the second moving frame, the second motor, the second turntable, and the internal clamping mechanism to move laterally, facilitating the movement of the internal clamping mechanism and the bearing ring towards the grinding and dust removal mechanisms. The second motor drives the second turntable to rotate, causing the bearing ring to rotate, facilitating the grinding of the outer ring. The two sets of drive units independently control the lateral position and rotational speed of the external and internal clamping mechanisms. After the inner ring of the bearing is ground, the two sets of drive mechanisms drive relative movement, causing the bearing ring to fit onto the internal clamping mechanism, completing the internal clamping of the bearing ring. The external clamping mechanism moves to the right and retracts, facilitating the grinding of the outer ring of the bearing ring. This independent drive ensures that the grinding of the outer and inner rings does not interfere with each other and can be quickly switched on the same platform.

[0012] Preferably, two stabilizing rods are fixedly installed on the top of the processing table. One end of each stabilizing rod passes through the first and second moving frames and is slidably connected to them. By fixing two stabilizing rods on the top of the processing table, with one end of each stabilizing rod passing through the first and second moving frames and being slidably connected to them, when the first and fifth electric push rods push the first and second moving frames to move laterally, the two moving frames slide synchronously along the stabilizing rods. The stabilizing rods provide precise linear guidance for the moving frames, preventing them from swaying or tilting during movement. This ensures that the axes of the first and second turntables are always perpendicular to the feed direction of the grinding roller, stabilizing the grinding contact angle. The stabilizing rods also bear most of the weight of the moving frames and their components, reducing the vertical load on the electric push rods and extending their service life.

[0013] Preferably, the grinding mechanism includes two eighth electric push rods, a lifting plate, a third motor, a worm gear, a worm wheel, a transmission shaft, a fourth motor, and a grinding roller. Both eighth electric push rods are fixedly mounted on the top of the bracket, and their output shafts are fixedly mounted on the top of the lifting plate. The third motor is fixedly mounted on the top of the lifting plate, and its output shaft is rotatably connected to the top of the lifting plate. The worm gear is fixedly sleeved on the output shaft of the third motor, and the worm wheel meshes with the worm gear. The top end of the transmission shaft is fixedly mounted on the bottom of the worm wheel, and the bottom end of the transmission shaft passes through the lifting plate and is fixedly mounted on the fourth motor. One end of the grinding roller is fixedly mounted on the fourth motor. On the output shaft of the motor, two eighth electric push rods in the grinding mechanism push the lifting plate up and down. The third motor drives the worm and worm wheel to rotate. The worm wheel drives the fourth motor and the grinding roller to rotate and swing through the transmission shaft. The worm and worm wheel have a large transmission ratio and self-locking characteristics, so that the grinding roller remains stable after the angle is adjusted and does not sag due to gravity. The swing angle of the grinding roller is adjustable so that it can adapt to the grinding requirements of the outer circle and inner hole of the bearing ring. The fourth motor drives the grinding roller to rotate at high speed to grind the inner and outer ring surfaces of the bearing ring. The eighth electric push rod controls the height of the grinding roller, which makes it easy for the grinding roller to fit the inner and outer rings of the bearing ring, and precise control improves the processing accuracy.

[0014] Preferably, a bearing sleeve is fixedly installed on the output shaft of the fourth motor, and a reinforcing rod is fixedly installed on the top of the bearing sleeve. The top end of the reinforcing rod is fixedly installed on the transmission shaft. By fixing the bearing sleeve on the output shaft of the fourth motor, fixing the top of the bearing sleeve to the reinforcing rod, and fixing the top end of the reinforcing rod to the transmission shaft, the bearing sleeve and the reinforcing rod together provide auxiliary support for the output shaft of the fourth motor, preventing the output shaft of the fourth motor from bending and deforming under the action of grinding force due to the long overhang of the grinding roller. The reinforcing rod transmits the supporting force to the transmission shaft to form a stable triangular support structure, which improves the rigidity and vibration resistance of the grinding roller when rotating, keeps the grinding roller stable during high-speed rotation and feeding, reduces vibration ripples during the grinding process, improves the surface finish and dimensional accuracy of the bearing ring, and extends the service life of the fourth motor.

[0015] Preferably, the dust removal mechanism includes a vacuum cleaner, an air inlet pipe, a telescopic pipe, a dust collection hood, two third electric push rods, and a U-shaped rod. The vacuum cleaner is fixedly installed on the front side of the bracket. The rear end of the air inlet pipe is fixedly connected to the front side of the vacuum cleaner. The rear end of the telescopic pipe is fixedly connected to the front end of the air inlet pipe, and the front end of the telescopic pipe is fixedly connected to the bottom of the dust collection hood. The two third electric push rods are respectively fixedly installed on the left and right sides of the vacuum cleaner. The U-shaped rod is fixedly installed at the bottom of the dust collection hood. The output shafts of the two third electric push rods are both fixedly installed on the rear side of the U-shaped rod. The negative pressure generated by the vacuum cleaner in the dust removal mechanism is transmitted to the dust collection hood through the air inlet pipe and the telescopic pipe, thus polishing the surface. The generated metal dust is captured by the dust collection hood and then sucked into the vacuum cleaner through the telescopic tube and air inlet pipe for filtration and collection. Two third electric push rods push the U-shaped rod and the dust collection hood to move back and forth, so that the dust collection hood extends when in use. When the bearing ring is transferred from the external clamping mechanism to the internal clamping mechanism, the dust collection hood is moved back and stored to avoid motion interference. The flexibility of the telescopic tube allows the dust collection hood to move freely in and out of the grinding position without affecting the air passage. The large opening area of ​​the dust collection hood can cover the space around the grinding area to effectively capture scattered dust, prevent dust from spreading into the working environment, and improve the working environment of the operators and the cleanliness of the equipment.

[0016] The beneficial effects of this invention are: 1. By setting an external clamping mechanism, four second electric push rods are activated to push four first clamping plates to clamp from the outside of the bearing outer ring. By setting an internal clamping mechanism, four sixth electric push rods are activated to push the second clamping plates to clamp from the inside of the bearing inner ring. The two clamping methods are integrated on the same platform. The grinding mechanism processes the surface of the outer ring or the inner ring as needed. One device has both outer ring clamping and inner ring clamping functions. There is no need to transfer the bearing ring to a dedicated inner ring grinding device, which reduces equipment investment costs and transfer time. It solves the problems of existing platforms that can only clamp the outer ring and cannot grind the inner ring and lack a dust removal structure. 2. A first baffle and a fourth electric push rod are fixed on one side of the first clamping plate. The fourth electric push rod pushes the first limiting plate to move towards the first baffle to clamp the end face of the bearing ring. A second baffle and a seventh electric push rod are fixed on one side of the second clamping plate. The seventh electric push rod pushes the second limiting plate to move towards the second baffle to clamp the end face of the bearing ring. The cooperation between the baffle and the limiting plate provides positioning and clamping force in the axial direction of the bearing ring, preventing the bearing ring from moving or falling off along the axial direction during rotational grinding. The travel of the limiting plate is adjustable to accommodate bearing rings of different thicknesses. The combination of axial clamping and radial clamping makes the bearing ring subject to multi-directional constraints during grinding, making the fixation more secure and reliable. 3. By activating the first electric push rod, the first moving frame, the first motor, and the first turntable move laterally, facilitating the movement of the external clamping mechanism and the bearing ring towards the grinding mechanism and the dust removal mechanism, thus enabling the grinding of the inner ring of the bearing ring. The first motor drives the first turntable to rotate, thereby causing the bearing ring to rotate, facilitating the grinding of the inner ring of the bearing ring. The fifth electric push rod pushes the second moving frame, the second motor, the second turntable, and the internal clamping mechanism to move laterally, facilitating the movement of the internal clamping mechanism and the bearing ring towards the grinding mechanism and the dust removal mechanism. The second motor drives the second turntable to rotate, thereby causing the bearing ring to rotate, facilitating the grinding of the outer ring of the bearing ring. The two sets of drive units independently control the lateral position and rotation speed of the external clamping mechanism and the internal clamping mechanism. After the inner ring of the bearing is ground, the two sets of drive mechanisms drive relative movement, causing the bearing ring to be placed on the internal clamping mechanism, completing the internal clamping of the bearing ring. The external clamping mechanism moves to the right and retracts, thus facilitating the grinding of the outer ring of the bearing ring. The independent drive here ensures that the grinding of the outer ring and the grinding of the inner ring do not interfere with each other and can be quickly switched on the same platform. 4. The lifting plate is raised and lowered by two eighth electric push rods in the grinding mechanism. The third motor drives the worm and worm wheel to rotate. The worm wheel drives the fourth motor and grinding roller to rotate and swing through the transmission shaft. The worm and worm wheel have a large transmission ratio and self-locking characteristics, so that the grinding roller remains stable after the angle is adjusted and does not sag due to gravity. The swing angle of the grinding roller is adjustable so that it can adapt to the grinding requirements of the outer circle and inner hole of the bearing ring. The fourth motor drives the grinding roller to rotate at high speed to grind the inner and outer ring surfaces of the bearing ring. The eighth electric push rod controls the height of the grinding roller, which makes it easy for the grinding roller to fit the inner and outer rings of the bearing ring. Precise control improves the processing accuracy. 5. The negative pressure generated by the vacuum cleaner in the dust removal mechanism is transmitted to the dust collection hood through the air inlet pipe and the telescopic pipe. The metal dust generated during grinding is captured by the dust collection hood and then sucked into the vacuum cleaner for filtration and collection through the telescopic pipe and the air inlet pipe. Two third electric push rods push the U-shaped rod and the dust collection hood to move back and forth, so that the dust collection hood extends when in use. When the bearing ring is transferred from the external clamping mechanism to the internal clamping mechanism, the dust collection hood is moved back and stored to avoid motion interference. The flexibility of the telescopic pipe allows the dust collection hood to move freely in and out of the grinding position without affecting the air passage. The large opening area of ​​the dust collection hood can cover the space around the grinding area and effectively capture the scattered dust, preventing the dust from spreading into the working environment and improving the working environment of the operators and the cleanliness of the equipment. This invention integrates external and internal clamping mechanisms to clamp the outer and inner rings of a bearing on the same platform, eliminating the need for dedicated bearing outer ring clamping and grinding equipment, thus reducing equipment costs and transfer time. The drive mechanism independently controls the rapid switching between the two clamping mechanisms, and the grinding mechanism angle is adjustable to adapt to the processing of the inner and outer rings. The dust removal mechanism collects dust simultaneously during grinding, improving the working environment and enhancing processing efficiency and environmental friendliness.
