Description

TECHNICAL FIELD

[0001] The application belongs to the field of bearing processing, and particularly relates to a full-automatic numerical control bearing composite grinding machine. BACKGROUND

[0002] A bearing is an important part in contemporary mechanical equipment, and its main function is to support a mechanical rotating body, reduce the friction coefficient in the movement process of the mechanical rotating body, and ensure the rotation precision. When the inner and outer rings of the bearing are processed, the following process flow is usually included: bar material-forging-turning-heat treatment-grinding processing-superfine processing-part final inspection-rust prevention and warehousing.

[0003] A grinding wheel is a tool with the widest application among abrasive tools, and can be used for rough grinding, semi-precise grinding, precise grinding, slotting and cutting of various profiles such as the outer circle, inner circle and plane of metal or non-metal workpieces. After the grinding wheel works for a period of time, the surface will be worn to a certain extent, and should be corrected to restore the grinding performance and correct geometric shape.

[0004] Firstly, when the bearing is ground, the sleeve ring is usually manually installed on the outside of the chuck, and is clamped and fixed from the inside by adjusting the chuck. Since the clamping force cannot be accurately controlled, the sleeve ring is easily left with clamping marks on the inner circle of the inner ring, and the sleeve ring is easily deviated in the axial direction or the radial direction or even the circumferential direction during the grinding process, which affects the bearing accuracy and performance. Secondly, since the sleeve ring is manually disassembled and assembled, the operation efficiency is low, and human factors also easily affect the clamping accuracy.

[0005] Secondly, for example, a three-servo grinding wheel dressing device and a multifunctional composite grinding machine disclosed in CN208629237U. In the technical solution, when the grinding wheel is dressed, the dresser support needs to be adjusted to the designed position by a first servo motor and a second servo motor, and the angle of the swing lever is adjusted by a third servo motor, so that the diamond pen on the swing lever dresses the grinding wheel. When the working surface of the grinding wheel is a special shape or a complex structure, the first servo motor and the second servo motor need to be adjusted to achieve the dressing. However, the first servo motor and the second servo motor mainly control the rapid movement in the two vertical directions along the horizontal direction to the designed position. When the working surface of the grinding wheel is dressed, the precision requirement cannot be met for precise dressing, so the dressing precision and stability still need to be further improved. At the same time, the three-servo control adaptability and fault tolerance also need to be further improved. SUMMARY

[0048] Intended effect:

[0049] 1. For the grinding process of bearing ring, the traditional inner ring outer channel grinding is to use multiple clamps to expand the inner ring from the inside, and then grind the outer channel with a grinding wheel. When the roller / clamp expands the inner ring, it cannot guarantee the pressing force, which can easily cause permanent damage to the inner diameter of the inner ring. The clamps are evenly distributed in the circumferential direction and cannot completely cover the inner wall of the bearing inner ring, which can easily cause the bearing inner ring to be squeezed and deformed. A set of energized coils generates a magnetic field to drive the drive sleeve towards the side close to the rotary disc. The elastic member first deforms elastically, and during the process, the moving ring squeezes the movable sleeve to the elastic member which does not deform. At the same time, the clamping jaw one is in contact with the inner wall of the workpiece, and the clamping jaw two is also close to the inner wall of the workpiece; another set of energized coils generates a magnetic field to drive the drive sleeve towards the side close to the rotary disc. The spring is squeezed, the drive rod two drives the clamping jaw two to abut on the inner wall of the workpiece and is inserted between the two clamping jaws one, thus completing the overall clamping operation of the inner circumference.

[0050] 2. Two groups of side rollers are arranged on the radial support frame, which can change the position of the central radial frame by adjusting the cylinder, adjust the distance between the two support ends, and then complete the adaptation to different sizes of steel rings. The driving cylinder is used to axially convey the workpiece.

[0051] 3. By using the mounting hole originally arranged on the end face of the bearing ring, a special mechanical hand clamping structure is adopted, which can complete the vertical automatic clamping and automatic release of the steel ring. That is, the compensation block can be adjusted relative to the position of the clamping block when the clamping structure moves vertically, so as to change the size of the coverage of the bottom surface of the compensation block and the clamping side of the clamping block. When clamping, the size is smaller than the size of the mounting hole and the steel ring is squeezed into the mounting hole to realize clamping. When released, the size is larger than the size of the mounting hole, so that it cannot enter the mounting hole again. After clamping the steel ring, it can fall under the middle area of the lifting frame under the action of gravity, so that the clamping and conveying of the steel ring are consistent every time.

[0052] 4. Compared with the three-servo system, the four-servo finishing system has higher control accuracy, stronger dynamic performance, higher flexibility, stronger anti-overload capability, and better stability, adaptability, fault tolerance, etc. These advantages help to improve the machining precision, machining efficiency and machining quality, so as to meet more strict and diversified machining requirements.

[0053] 5. The inventor has designed for many years and has feedback from customers on the problem that grinding fluid needs to be applied to the grinding wheel and workpiece during grinding, and the grinding fluid can carry grinding dust, which can easily enter the slide and damage the slide, resulting in the inability to complete ultra-high precision machining of the workpiece feeding accuracy. Therefore, the end and side of the slide assembly are improved, the end is blocked by end cover two and end cover one, and the surface of the extension plate is cleaned by the water scraping plate, and the side is adapted by multiple blocking strips and water blocking grooves to form multiple sealing structures arranged up and down to prevent the grinding fluid from entering.

[0054] 6. A high-pressure gas blowing part is further arranged on the inner side of the slide assembly, which can blow high pressure when the upper slide slides relative to the lower fixed table, forming a directional airflow from inside to outside to form a dynamic sealing structure to prevent the grinding fluid from entering; when the upper slide is stationary relative to the lower fixed table, the top of the waterproof rubber strip will be attached to the inner side of the upper wall of the water blocking groove to form a static sealing structure to prevent the grinding fluid from entering. The selective operation of dynamic and static sealing can effectively realize the sealing operation of the feeding work, thereby ensuring that the slide assembly has a long service life under complex working conditions, and also ensures the machining precision of the grinding machine.

[0085] like Figures 3-6 As shown, the steel ring full circumference mounting assembly includes a mounting frame 4011, a rotary shaft 4012, a servo motor 4013 and a rotary disk 4014. The servo motor 4013, the rotary shaft 4012 and the rotary disk 4014 are mounted on the mounting frame 4011. The output end of the servo motor 4013 is mounted on the rotary disk 4014 through the rotary shaft 4012. The rotary disk 4014 is provided with an energized coil 4015. The rotary disk 4014 is equipped with a clamping structure. When the energized coil 4015 is energized to generate a magnetic field, it drives the clamping structure to fix the workpiece on the full circumference.

The moving frame 14 is provided with a scale bar 141, and the swing arm 12 is provided with a scale angle code 121, which is used for aligning the corresponding scale on the scale bar 141.

[0089] In the implementation, the steel ring feeding and discharging assembly 30 feeds the steel ring to the mounting station, and then the radial support frame 40 is driven by the driving cylinder 50 to approach the rotary disc 32, so that the steel ring is attached to the surface of the rotary disc 32. After the magnetic field is generated by energizing the coil 4015 of the clamping structure, the workpiece is clamped and fixed.

[0115] When the steel ring needs to be clamped:

[0116] The X-axis linear module 31 and the Y-axis linear module 32 adjust the lifting frame 341 to be located at the top of the steel ring, the lifting frame 341 is vertically lowered through the Z-axis linear module 33, the bottom of the compensation block 344 of the clamping block 343 on the inclined surface first contacts the outer wall of the steel ring, and as the lifting frame 341 continues to be lowered, it moves upward along the compensation inclined surface through the cooperation of the guide slot 345 and the guide block 347, until the hook head 349 at the end of the hook rod 348 moves from the entrance of the upward long groove 3461 to the entrance of the downward short groove 3462, and as the lifting frame 341 continues to be lowered, the clamping block 343 and the compensation block 344 move outward and upward relative to the lifting frame 341, until the opposite side of the compensation block 344 is separated from the outer periphery of the steel ring and is attached to the end face, and the clamping block 343 moves downward relative to the compensation block 344, that is, the hook head 349 enters the entrance of the upward short groove 3463, and the clamping block 343 also moves downward relative to the lifting frame 341 after the compensation block 344 moves downward, ensuring that the opposite side of the compensation block 344 is always attached to the end face of the steel ring, and the distance between the top of the clamping side of the clamping block 343 and the bottom of the compensation block 344 is less than or equal to the width of the clamping area, and as the lifting frame 341 continues to be lowered, the clamping side of the compensation block 344 and the clamping block 343 enters the clamping area and is automatically hooked with the clamping area.

When the bottom of the steel ring falls on the workstation, as the lifting frame 341 continues to be lowered, the bottom of the compensation block 344 will first abut against the bottom of the clamping area, and as it continues to be lowered, the hook head 349 will enter the entrance of the downward long slot 3464, and then as it continues to be lowered, the compensation block 344 and the clamping block 343 will be relative to the clamping area. Move outward until the compensation block 344 and the clamping block 343 are completely separated from the clamping area. After separating from the clamping area, the compensation block 344 moves downward relative to the clamping block 343, that is, the hook head 349 enters the entrance of the upward long groove 3461. At this time, the distance between the bottom surface of the compensation block 344 and the top surface of the clamping side of the clamping block 343 is greater than the width of the clamping area, and it is ensured that the top surface of the compensation block 344 does not separate from the top end surface of the steel ring.
