Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing processing technology, and in particular to a feeding device for a bearing end face grinding machine. Background Technology
[0002] Bearing grinding equipment mainly refers to bearing grinding machines, which are specialized devices for grinding bearings. They typically include various types such as external cylindrical grinding machines, internal cylindrical grinding machines, and surface grinding machines. These grinding machines are selected and used according to different bearing types and grinding requirements. The bearing grinding process refers to the process of machining the bearing surface using grinding tools. Its purpose is to remove excess material from the bearing surface, improve surface quality, and achieve specified dimensional and precision requirements. The bearing grinding process usually includes three stages: rough grinding, semi-finish grinding, and finish grinding. Each stage requires different grinding tools and grinding parameters to achieve the best grinding effect. Commonly used grinding tools in bearing grinding include grinding wheels, abrasive belts, and grinding pads, with grinding wheels being the most commonly used. During grinding, the grinding wheel rotates at high speed to grind the bearing surface. By continuously adjusting the grinding parameters and selecting the grinding wheel, efficient and precise machining of the bearing surface can be achieved.
[0003] In the process of machining bearings, bearings need to be positioned accurately on the grinding machine. Some existing bearing grinding machines rely on manual operation or simple mechanized conveying during the feeding process, which has the problems of low feeding efficiency and insufficient positioning accuracy, and it is difficult to meet the needs of mass production. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing bearing grinding machines, which rely heavily on manual operation or simple mechanized conveying during the feeding process, resulting in low feeding efficiency and insufficient positioning accuracy, and making it difficult to meet the needs of mass production. This invention provides a feeding device for bearing end face grinding machines.
[0005] The purpose of this utility model is achieved through the following technical solution: a feeding device for a bearing end face grinding machine, including an outer shell, a grinding machine processing platform installed inside the outer shell, an infrared signal transmitter installed in the middle of the grinding machine processing platform, a feeding conveyor belt installed at the feeding end of the outer shell, a first electric slide installed at the inner top of the outer shell, the first electric slide being located above the grinding machine processing platform and the feeding conveyor belt, an electric push rod installed at the moving end of the first electric slide, a clamping assembly installed at the lifting end of the electric push rod, and an infrared signal receiver corresponding to the infrared signal transmitter installed in the middle of the clamping assembly;
[0006] A photoelectric sensor is installed at the unloading end of the feeding conveyor belt, and an industrial control computer is installed on the outer casing. The industrial control computer is connected to the feeding conveyor belt, the first electric slide, the electric push rod, the clamping assembly, and the photoelectric sensor.
[0007] By combining an infrared receiver located on the clamping assembly with an infrared transmitter on the grinding machine platform, the clamping assembly can accurately place the bearing workpiece in the processing area of the grinding machine platform when clamping the bearing workpiece. This not only saves labor but also provides high positioning accuracy for the bearing workpiece, effectively improving processing efficiency and meeting the needs of mass production of bearing workpieces. Simultaneously, a photoelectric sensor can position the bearing workpiece at the discharge end of the feed conveyor belt. When the photoelectric sensor detects that the bearing workpiece has moved to the discharge end of the feed conveyor belt, it sends a signal to the industrial control computer. The industrial control computer then controls the feed conveyor belt to temporarily move, keeping the bearing workpiece at the discharge end of the feed conveyor belt in a designated position awaiting clamping by the clamping assembly, ensuring the stability of equipment operation.
[0008] A further technical solution is that the clamping assembly includes a clamping disk, on which three sets of second electric slides arranged in a circular array are mounted. An infrared signal receiver is located at the center of the three sets of second electric slides. All three sets of second electric slides are connected to an industrial control computer. Each of the three sets of second electric slides has a chuck installed on its moving end. By setting the three sets of second electric slides to drive the chucks to move synchronously on the clamping disk, the clamping assembly can clamp bearing workpieces of different sizes, meeting the equipment's requirements for processing bearing workpieces of different sizes and improving the applicability of the clamping assembly.
[0009] A further technical solution is that anti-slip rubber strips are installed on the inner side of all three sets of jaws. By setting anti-slip rubber strips, the stability of the bearing workpiece can be improved when the jaws clamp the bearing workpiece, while avoiding scratches on the outer surface of the bearing workpiece.
[0010] A further technical solution is that each of the three sets of second electric slides is equipped with a displacement sensor corresponding to the chuck, and the displacement sensor is connected to the industrial control computer;
[0011] The inner bottom wall of the outer casing has a discharge port, which is located between the grinding machine processing platform and the feeding conveyor belt. An inclined plate is installed at the lower part of the discharge port, and a collection box is installed at the discharge end of the inclined plate.
[0012] By setting a displacement sensor connected to the chuck, the movement distance of the chuck when clamping the bearing workpiece can be detected. The industrial control computer can then calculate the size of the bearing workpiece based on the movement distance of the chuck. When the size of the bearing workpiece is found to be non-compliant, the industrial control computer controls the first electric slide, electric push rod, and clamping assembly to discharge the bearing workpiece through the discharge port into the collection box for recycling. This prevents other types of bearings from being mixed into the raw materials and causing damage to the grinding machine during subsequent grinding. At the same time, an inclined plate and collection box are set up to recycle non-compliant bearing workpieces.
[0013] A further technical solution involves installing a cylinder connected to an industrial control computer on one side of the grinding machine processing platform. The telescopic end of the cylinder is equipped with a push plate corresponding to the grinding machine processing platform, and the discharge end of the outer casing is equipped with a discharge conveyor belt corresponding to the grinding machine processing platform. The discharge conveyor belt and the push plate are symmetrical about the grinding machine processing platform. By setting up the cylinder and push plate in cooperation, the workpiece processed on the grinding machine processing platform is pushed onto the discharge conveyor belt, thereby improving the material discharge efficiency and thus improving the overall processing efficiency of the equipment.
[0014] This utility model has the following advantages: By setting an infrared signal receiver on the clamping assembly and cooperating with an infrared signal transmitter on the grinding machine processing platform, this utility model enables the clamping assembly to accurately place the bearing workpiece on the processing area of the grinding machine processing platform when clamping and loading the bearing workpiece. This not only saves labor, but also has high positioning accuracy for the bearing workpiece, effectively improving the processing efficiency of the bearing workpiece and meeting the needs of mass production of bearing workpieces.
[0015] By setting a displacement sensor connected to the chuck, the movement distance of the chuck when clamping the bearing workpiece can be detected. The industrial control computer can then calculate the size of the bearing workpiece based on the movement distance of the chuck. When the size of the bearing workpiece is found to be non-compliant, the industrial control computer controls the first electric slide, electric push rod, and clamping assembly to discharge the bearing workpiece through the discharge port into the collection box for recycling. This prevents other types of bearings from being mixed into the raw materials and causing damage to the grinding machine during subsequent grinding. At the same time, an inclined plate and collection box are set up to recycle non-compliant bearing workpieces. Attached Figure Description

[0027] like Figures 1-4 As shown, a feeding device for a bearing end face grinding machine includes a housing 1, a grinding platform 2 installed inside the housing 1, an infrared signal transmitter 8 installed in the middle of the grinding platform 2, a feeding conveyor belt 3 installed at the feeding end of the housing 1, a first electric slide 4 installed at the inner top of the housing 1, the first electric slide 4 being located above the grinding platform 2 and the feeding conveyor belt 3, an electric push rod 5 installed at the moving end of the first electric slide 4, a clamping assembly 6 installed at the lifting end of the electric push rod 5, and an infrared signal receiver 15 corresponding to the infrared signal transmitter 8 installed in the middle of the clamping assembly 6.
[0028] A photoelectric sensor 9 is installed at the unloading end of the feeding conveyor belt 3, and an industrial control computer 7 is installed on the outer casing 1. The industrial control computer 7 is connected to the feeding conveyor belt 3, the first electric slide 4, the electric push rod 5, the clamping assembly 6 and the photoelectric sensor 9 respectively.
[0029] By setting an infrared receiver 15 located on the clamping assembly 6 in conjunction with an infrared signal transmitter 8 on the grinding machine processing platform 2, the clamping assembly 6 can accurately place the bearing workpiece on the processing area of the grinding machine processing platform 2 when clamping the bearing workpiece for feeding. This not only saves labor but also provides high positioning accuracy for the bearing workpiece, effectively improving the processing efficiency of the bearing workpiece and meeting the needs of mass production of bearing workpieces. At the same time, a photoelectric sensor 9 can position the bearing workpiece at the discharge end of the feeding conveyor belt 3. When the photoelectric sensor 9 detects that the bearing workpiece has moved to the discharge end of the feeding conveyor belt 3, it sends a signal to the industrial control computer 7. The industrial control computer 7 controls the feeding conveyor belt 3 to temporarily move, so that the bearing workpiece at the discharge end of the feeding conveyor belt 3 waits in the designated position for clamping by the clamping assembly 6, ensuring the stability of equipment operation.
[0030] The clamping assembly 6 includes a clamping disk 601, on which three sets of second electric slides 602 arranged in a circular array are mounted. An infrared signal receiver 15 is located at the center of the three sets of second electric slides 602. All three sets of second electric slides 602 are connected to an industrial control computer 7. Each of the three sets of second electric slides 602 has a chuck 603 mounted on its moving end. By setting the three sets of second electric slides 602 to drive the chuck 603 to move synchronously on the clamping disk 601, the clamping assembly 6 can clamp bearing workpieces of different sizes, meet the equipment's requirements for processing bearing workpieces of different sizes, and improve the applicability of the clamping assembly 6.
[0031] Anti-slip rubber strips 604 are installed on the inner side of each of the three sets of jaws 603. By setting the anti-slip rubber strips 604, the stability of the bearing workpiece can be improved when the jaws 603 clamp the bearing workpiece, while avoiding scratches on the outer surface of the bearing workpiece.
[0032] Each of the three sets of second electric slides 602 is equipped with a displacement sensor corresponding to the chuck 603, and the displacement sensor is connected to the industrial control computer 7.
[0033] The inner bottom wall of the outer shell 1 is provided with a discharge port 10, which is located between the grinding machine processing platform 2 and the feeding conveyor belt 3. An inclined plate 11 is installed at the lower part of the discharge port 10, and a collection box 12 is installed at the discharge end of the inclined plate 11.
[0034] By setting a displacement sensor connected to the chuck 603, the movement distance of the chuck 603 when clamping the bearing workpiece can be detected. The industrial control computer 7 can then calculate the size of the bearing workpiece based on the movement distance of the chuck 603. When the size of the bearing workpiece is detected to be non-compliant with the standard, the industrial control computer 7 controls the first electric slide 4, the electric push rod 5, and the clamping assembly 6 to discharge the bearing workpiece through the discharge port 10 into the collection box 12 for recycling. This prevents other types of bearings from being mixed into the raw materials and causing damage to the grinding machine during subsequent grinding. At the same time, the inclined plate 11 and the collection box 12 are set to recycle non-compliant bearing workpieces.
[0035] A cylinder 13 connected to an industrial control computer 7 is installed on one side of the grinding machine processing platform 2. A push plate 14 corresponding to the grinding machine processing platform 2 is installed at the telescopic end of the cylinder 13. A discharge conveyor belt 16 corresponding to the grinding machine processing platform 2 is installed at the discharge end of the outer shell 1. The discharge conveyor belt 16 and the push plate 14 are symmetrical about the grinding machine processing platform 2. By setting the cylinder 13 and the push plate 14 to cooperate, the workpiece processed on the grinding machine processing platform 2 is pushed onto the discharge conveyor belt 16, thereby improving the material discharge efficiency and thus improving the overall processing efficiency of the equipment.
[0036] The working process of this utility model is as follows: When using the feeding device, the feeding conveyor belt 3 first carries the bearing workpiece to be processed into the outer shell 1. When the photoelectric sensor 9 at the discharge end of the feeding conveyor belt 3 detects that the workpiece on the feeding conveyor belt 3 has reached the feeding position, the photoelectric sensor 9 sends a signal to the industrial control computer 7. The industrial control computer 7 controls the first electric slide 4 to move the electric push rod 5 to the designated position. The electric push rod 5 controls the clamping assembly 6 to descend to the designated position. The second electric slide 602 on the clamping assembly 6 controls the jaw 603 to move and clamp the bearing workpiece. At the same time, the displacement sensor connected to the jaw 603 can detect the moving distance of the jaw 603 when clamping the bearing workpiece. Thus, the industrial control computer 7 can calculate the size of the bearing workpiece based on the moving distance of the jaw 603. When the size of the bearing workpiece is detected to meet the standard, the first electric slide 4, the electric push rod 5, and the clamping assembly... The components 6 work together to move the bearing workpiece to a designated position above the grinding machine processing platform 2. When the infrared receiver 15 on the clamping plate 601 receives the signal from the infrared transmitter 8, it indicates that the designated position has been reached. At this time, the electric push rod 5 drives the clamping assembly 6 to descend and place the workpiece on the processing area of the grinding machine processing platform 2. The first electric slide 4 drives the electric push rod 5 and the clamping assembly 6 to reset. Then the grinding machine begins to process the bearing workpiece. After processing, the cylinder 13 and the push plate 14 work together to push the processed workpiece on the grinding machine processing platform 2 onto the discharge conveyor belt 16 to complete the discharge. In addition, when the industrial control computer 7 detects that the size of the bearing workpiece does not meet the standard through the displacement sensor connected to the chuck 603, the industrial control computer 7 controls the first electric slide 4, the electric push rod 5 and the clamping assembly 6 to discharge the bearing workpiece through the discharge port 10 into the collection box 12 for recycling.
[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
