Detailed ways

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 described embodiments 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 creative work are within the scope of protection of the present invention.

Please refer to Figures 1-7. In order to solve the problem of forming a grinding dead point at the clamping point or the supporting point, the distance between the two clamping discs is adjusted to achieve clamping of spheres of different sizes, so that there is no need to replace the clamping disc. The spherical workpiece is driven to rotate by the roller to adjust the polishing and grinding position. The spherical workpiece is moved in different directions by changing the rolling angle of the roller, so that the workpiece does not rely on the machine tool to drive the workpiece to rotate. At the same time, no grinding dead angle is generated, and the workpiece is fully polished without removing and reinstalling the workpiece during the polishing process. The present invention provides a technical solution: a spherical polishing device, including a base plate 1, a spherical workpiece 2, a clamping disc 4, and a roller 5. The base plate 1 is symmetrically provided with clamping discs 4, and the two clamping discs 4 clamp the spherical workpiece 2 together. The spherical workpiece 2 is polished by the grinding head 3. The clamping disc 4 is provided with a roller 5, and the roller 5 can drive the spherical workpiece 2 to rotate to adjust the polishing position. The clamping disc 4 is installed on a support rod 6, and the support rod 6 is slidably arranged on the base plate 1 to clamp spherical workpieces 2 of different sizes. In this application, electrical components such as motors, cylinders, push rods, and grinding heads all use existing models. When in use, the spherical workpiece 2 is placed between the two clamping plates 4, the distance between the two clamping plates 4 is adjusted so that the two clamping plates 4 clamp the spherical workpiece 2, and the grinding head 3 is used for grinding. During the grinding process, the roller 5 is used to drive the spherical workpiece 2 to roll. According to needs, only one side of the roller 5 can be used or the rollers 5 on both sides can be used at the same time. When the rollers 5 on both sides are used at the same time, it is necessary to adjust the rotation directions of the rollers 5 on both sides to be consistent, so as to avoid the spherical workpiece 2 from rotating and being damaged by the rollers 5 due to the inconsistent rotation directions of the two rollers 5. In the process of using the rollers 5, the extension position of the rollers 5 is adjusted according to the size of the spherical workpiece 2 so that the rollers 5 can fit the spherical workpiece 2. When it is necessary to adjust the grinding position of the spherical workpiece 2, the motor is started to roll the rollers 5, or the rollers 5 are withdrawn and adjusted to fit after the angle is adjusted so that the spherical workpiece 2 can rotate in different directions to achieve comprehensive grinding, or the angle of the rollers 5 is adjusted to perform fixed-point grinding on a specific position or area under a specific rotation condition, so as to avoid grinding dead angles and achieve comprehensive grinding.

To further facilitate the rotation of the spherical workpiece 2 , the clamping plate 4 is provided with an inclined surface at the opening to match the spherical workpiece 2 , and a plurality of balls 401 are embedded on the inclined surface. The balls 401 are rollingly connected to the spherical workpiece 2 to match the rotation of the spherical workpiece 2 .

In order to clamp spherical workpieces of different sizes, the clamping disc 4 is fixedly connected to one end of the bracket 402, and the other end of the bracket 402 is fixed to the upper end of the support rod 6. The lower end of the support rod 6 cooperates with the support rod screw 601 ball screw pair, and the support rod screw 601 is rotatably connected to the bottom plate 1 and driven by the motor. When in use, the spherical workpiece 2 is placed between the two clamping discs 4, and the motor is started. The motor drives the support rod screw 601 to rotate, thereby moving the support rod 6, and the support rod 6 drives the bracket 402 to move, and the bracket 402 drives the two clamping discs 4 to approach each other, so that the spherical workpiece 2 is clamped; when the grinding is completed, the two support rod screws 601 are rotated in the opposite direction, so that the two clamping discs 4 release the spherical workpiece 2, and the spherical workpiece 2 can be removed at this time.

In order to realize the rotation of spherical workpieces 2 of different sizes, the roller 5 is rotatably connected to the wheel frame 501 and driven by a motor, the motor is fixed to the wheel frame 501, and the roller 5 can be extended and rotated in the clamping plate 4. The roller 5 can be made of a flexible material with a large friction coefficient, such as rubber, as needed. The extension amount of the roller 5 is determined according to the size of the spherical workpiece 2, the angle of the roller 5 is adjusted according to the required rotation direction, and the roller 5 is driven to rotate by the motor.

To adapt to spherical workpieces 2 of different sizes, the wheel frame 501 is fixedly connected to one end of the long gear 502, and the other end of the long gear 502 is rotatably connected to the square slider 503. The square slider 503 cooperates with the roller screw 504 ball screw pair, and the roller screw 504 is fixedly connected to the worm gear 505. The worm gear 505 meshes with the worm 506. One end of the worm 506 extends out of the bracket 402. The long gear 502, the roller screw 504, the worm gear 505, and the worm 506 are rotatably connected in the bracket 402, and the square slider 503 is slidably connected in the bracket 402. A sliding groove adapted to the shape of the square slider 503 is provided in the bracket 402 to prevent the square slider 503 from rotating with the roller screw 504. A hole that can accommodate the roller screw 504 is provided in the long gear 502 to avoid affecting the retraction of the roller 5. When in use, the worm 506 is rotated, the worm 506 drives the worm wheel 505 to rotate, the worm wheel 505 drives the roller screw 504 to rotate, the roller screw 504 rotates to move the square slider 503, the square slider 503 drives the long gear 502 to move, the long gear 502 drives the wheel frame 501 to move, the wheel frame 501 drives the roller 5 to move and adjust the extension position to match the spherical workpieces 2 of different sizes. The setting of the long gear 502 ensures that the long gear 502 is always engaged with the adjusting gear 507 during the process of adjusting the extension distance of the roller 5.

In order to facilitate the adjustment of the angle of the roller 5 so as to drive the spherical workpiece 2 to perform different rotations, the long gear 502 is meshed with the adjusting gear 507, and the adjusting gear 507 is rotatably connected to the bracket 402. A positioning assembly is provided on the adjusting gear 507. The positioning assembly includes a claw 508, a claw spring 509, and a tooth 510. The adjusting gear 507 is provided with a tooth 510. The arc length occupied by the tooth 510 is not less than π/2 and not greater than 2π, so as to avoid the problem of motor wiring being entangled due to excessive rotation. The tooth 510 is engaged with the head of the claw 508, and the tail of the claw 508 is fixedly connected to one end of the claw spring 509. The other end of the claw spring 509 is fixed in the bracket 402. The claw 508 is slidably connected in the bracket 402. The two ends of the tooth 510 are provided with a limiting groove 511, so that the adjusting gear 507 can only be adjusted within the range of the tooth 510 to prevent the claw 508 from sliding out of the range of the tooth 510. When adjustment is needed, the roller 5 is first withdrawn a certain distance to prevent the roller 5 from rotating against the spherical workpiece 2 and causing wear on the spherical workpiece 2 and the roller 5. Then the adjusting gear 507 is rotated, and the adjusting gear 507 drives the long gear 502 to rotate, and the long gear 502 drives the wheel frame 501 to rotate, and the wheel frame 501 drives the roller 5 to rotate to adjust the angle. During this process, the claw 508 cooperates with the tooth 510 to position the adjusting gear 507 to prevent the adjusting gear 507 from rotating at will and affecting the angle of the roller 5. When the claw 508 enters the limit groove 511, it is locked, so that the adjusting gear 507 can no longer continue to rotate to the side of the claw 508 away from the tooth 510, thereby avoiding the problem of motor wiring entanglement caused by rotating more than one circle.
