[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0016] See also Figures 1 to 3 The utility model provides a technical solution: an automatic bearing protection tooling for the camshaft grinding process, comprising a mounting seat 1, on which are provided: a support member 2, a connecting frame 3, a driving mechanism and an oil supply mechanism, a plurality of support members 2 are respectively arranged on the mounting seat 1; a plurality of connecting frames 3 are respectively installed on one side of a plurality of support members 2 by screws; the driving mechanism is installed on a plurality of connecting frames 3 and the support members 2; the oil supply mechanism is installed on a plurality of connecting frames 3 and a plurality of support members 2.
[0017] During the specific implementation process, it should be noted that the workpiece is placed on the drive mechanism, and then the drive mechanism is started. The bearing is clamped and fixed through the automatic closing of the drive mechanism. After the bearing is correctly placed, the oil supply mechanism starts to work, and clean grinding oil is automatically delivered to the drive mechanism through the oil supply mechanism. The drive mechanism is controlled by a cylinder 4 to control the opening and closing of the fastener 5 and the support 2. An electromagnetic sensor is provided on the cylinder 4 to check whether the cylinder 4 is in place and ensure that the upper cover 7 and the lower cover 6 are completely opened and closed. The oil supply mechanism forms a positive pressure in the upper cover 7 and the lower cover 6 by continuously supplying liquid, which helps to prevent grinding mud from entering the inside of the bearing during the grinding process, thereby maintaining the cleanliness of the bearing. The cutting fluid is continuously discharged outward from the gap between the upper cover 7 and the lower cover 6 and the camshaft, further blocking the invasion of grinding mud. Since each camshaft has five bearings, five support members 2 are provided with five protection units. Each unit automatically determines whether the protective cover is in place through the coordinated work of the cylinder 4 and the electromagnetic sensor, thereby ensuring the protection effect and ease of operation. The device realizes fully automatic protection without the need for manual intervention in the installation and removal of the protective cover, effectively improving production efficiency and reducing labor costs. The automatic closing and opening of the protective device and the continuous supply of cutting fluid are ensured through the coordination of the cylinder 4 and the sensor, thereby solving the cleanliness problem at the source and ensuring the quality of the grinding process and the protection effect of the bearings.
[0018] In some examples, further, the driving mechanism includes: a cylinder 4, a fastener 5, a lower cover 6 and an upper cover 7, the ends of several cylinders 4 are mounted on the end of the connecting frame 3 through a hinge; several fasteners 5 are respectively mounted on the telescopic ends of several cylinders 4, and are rotatably connected to several support members 2; several lower covers 6 are respectively arranged on the top ends of several support members 2; several upper covers 7 are mounted on the inner sides of several fasteners 5, and match several lower covers 6.
[0019] During the specific implementation process, it should be noted that when the bearing needs to be clamped, the cylinder 4 begins to extend, and the fastener 5 connected to its end begins to work together; the fastener 5 is connected to the telescopic end of the cylinder 4 and moves with the movement of the cylinder 4; the main function of the fastener 5 is to convert the linear motion of the cylinder 4 into the rotational motion of the upper cover 7; with the movement of the fastener 5, the upper cover 7 begins to rotate; the upper cover 7 requires precise control by the cylinder 4 to ensure that its end can accurately fit with the lower cover 6; the lower cover 6 matches the upper cover 7 so that the two can form a closed space; when the end of the upper cover 7 fits with the lower cover 6, the closed space wraps the bearing therein, thereby protecting the bearing; effectively preventing external contaminants from entering the bearing and maintaining the cleanliness of the bearing inside during the grinding process; this device is triggered by the telescopic action of the cylinder 4, and transmits power to the upper cover 7 through the fastener 5, and finally realizes the cooperation between the upper cover 7 and the lower cover 6, completing the clamping and protection of the bearing.
[0020] In some examples, further, the inner sides of several upper covers 7 and several lower covers 6 are semicircular; the lower cover 6 is fixed to the top of the support 2, and its semicircular inner side cooperates with the semicircular inner side of the upper cover 7 to form a complete circular space; the bearing is wrapped and protected; a continuous, dead-angle-free protection area is formed, which effectively isolates external pollutants and keeps the bearings clean during the grinding process; the protection effect is improved while maintaining the simplicity and automation of operation, which helps to improve the efficiency of the camshaft grinding process and the protection quality of the bearings.
[0021] In some examples, further, the oil supply mechanism includes: a clean oil pipe 8 and a passage 9, the ends of several clean oil pipes 8 pass through several connecting frames 3 and are connected to the sides of several support members 2; several passages 9 are respectively opened on several support members 2, and the top ends pass through several lower covers 6.
[0022] During the specific implementation process, it should be noted that the oil supply mechanism is composed of a plurality of clean oil pipes 8, the ends of the clean oil pipes 8 are directly connected to the side of the support 2; the passage 9 extends to the top and passes through the lower cover 6; when the oil supply mechanism starts working, the clean grinding oil is transported to the passage 9 through the clean oil pipe 8 and flows upward until it reaches the top of the passage 9 and passes through the lower cover 6; the grinding oil is evenly transported to the inner side of the lower cover 6, and contacts the closed space formed by the upper cover 7 and the lower cover 6, providing continuous lubrication and cleaning for the bearing; the passage 9 ensures that the grinding oil can form a stable oil film on the bearing surface, which not only helps to reduce friction and wear during the grinding process, but also effectively takes away the heat energy generated by grinding to prevent the bearing from overheating; the oil supply mechanism realizes continuous oil supply and protection of the bearing through the coordinated work of the clean oil pipe 8 and the passage 9, ensures the smooth progress of the camshaft grinding process, and at the same time improves the service life and grinding quality of the bearing; the oil supply effect is automatic and does not require manual intervention, which significantly improves production efficiency and operation safety.

[0024] During the specific implementation process, it should be noted that the limit groove 10 provides a guide rail and limit for the longitudinal movement of the slider 12 in the adjustment assembly. The slider 12 matches the limit groove 10 and is mounted on the fixed base 11 via an adjustment screw. The slider 12 can slide longitudinally within the limit groove 10 to achieve fine adjustment of the position of the support member 2. Rotating the adjustment screw can push the slider 12 to move within the limit groove 10, thereby adjusting the distance between the fixed bases 11. By rotating the adjustment screw, the slider 12 is driven to move to the appropriate position within the limit groove 10, and finally the slider 12 is fixed to complete the adjustment of the support member 2. It can flexibly adapt to camshaft bearings of different specifications, ensuring the accuracy and efficiency of the grinding process.
[0025] In some examples, further, electromagnetic sensors are installed on several cylinders 4. The electromagnetic sensor can accurately capture the movement state of the cylinder 4. When the cylinder 4 extends or contracts, the electromagnetic sensor monitors the position changes of the cylinder 4 in real time and converts these changes into electrical signals. The signals collected by the electromagnetic sensor are transmitted to the control system, which analyzes and processes the signals to ensure that the movement of the cylinder 4 meets the predetermined working requirements. Among them, the control system is a common control device in the control of the cylinder 4. It is not described in detail here. It can accurately monitor the stroke position of the cylinder 4 to ensure that the cylinder 4 can reach the required precise position in the process of extending to the upper cover 7 and fitting with the lower cover 6. Through the installation of electromagnetic sensors, the automatic bearing protection tooling during the camshaft grinding process can realize automatic control, improve the accuracy and safety of the operation, and ensure the smooth progress of the grinding process.
