Detailed Description of the Preferred Embodiment

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0022] Refer to Figures 1 to 3 As shown, a fixing device for processing wear-resistant balls includes a table 1, a driving mechanism arranged in the middle of the top surface of the table 1 for bearing and driving the grinding ball to rotate, a synchronous polishing and wiping mechanism arranged outside the driving mechanism, and a positioning mechanism arranged above the polishing and wiping mechanism for preventing the grinding ball from running off during polishing;

[0023] The polishing and wiping mechanism includes two fixing plates 4 vertically fixed at the front and rear ends of the top surface of the table 1. Two pushing blocks 5 are symmetrically slidably arranged between the two fixing plates 4. An abrasive paper 6 is glued to the inner wall of one of the pushing blocks 5, and a sponge sheet 7 is glued to the inner wall of the other pushing block 5. A transmission component is arranged between the two pushing blocks 5;

[0024] By setting the grinding and wiping mechanism, when the grinding ball needs to be polished, the grinding ball can be placed on the driving mechanism, and then the two pushing blocks 5 on both sides of the grinding ball are pushed to move toward each other by the transmission component. At this time, the sandpaper 6 and the sponge sheet 7 are closed and close to the surface of the grinding ball. The grinding ball is driven by the driving mechanism to rotate at high speed, and the sandpaper 6 is used to grind the surface of the grinding ball, and the sponge sheet 7 is used to wipe the residual dust on the surface of the grinding ball after grinding. In this way, the sandpaper 6 and the sponge sheet 7 can be used to grind and wipe the grinding ball at the same time, thereby solving the problem that the grinding ball cannot be polished and wiped at the same time in the prior art, and reducing the problem of reducing the processing efficiency of the steel ball.

[0025] Further, refer to Figures 1 to 3 As shown, it is worth noting that the driving mechanism includes a load-bearing gear 2 arranged on the top surface of the table 1, the top surface of the load-bearing gear 2 is provided with a spherical concave surface, a rotating shaft is fixed to the bottom surface of the load-bearing gear 2, and the rotating shaft is rotatably connected to the table 1, and an arch-shaped support frame 14 is arranged on one side of the load-bearing gear 2, the support frame 14 is fixed to the top surface of the table 1, and a motor 13 is fixed to the top surface of the support frame 14, and the output shaft of the motor 13 rotates and penetrates into the inner side of the support frame 14 and is fixed with a transmission gear 3, and the transmission gear 3 is meshed with the load-bearing gear 2;

[0026] By setting the driving mechanism, the grinding ball is placed on the spherical concave surface of the top surface of the load-bearing gear 2, and the positioning mechanism is started to position the grinding ball, and the motor 13 is started, and the motor 13 is used to drive the transmission gear 3 to rotate, and then the load-bearing gear 2 is rotated, driving the grinding ball on the load-bearing gear 2 to rotate synchronously.

[0027] Further, refer to Figures 1 to 3 It is worth noting that the transmission component includes two double-sided lead screws 12 symmetrically arranged between the two push blocks 5, and the two ends of the double-sided lead screws 12 are respectively threaded through the two push blocks 5 and are connected to the two fixed plates 4 for corresponding rotation;

[0028] One end of the double-sided lead screw 12 passes through one of the fixed plates 4 and is tightly sleeved with a pulley 8. The two pulleys 8 are connected by a transmission belt, and a rotating handle is fixed on one of the pulleys 8.

[0029] Through the setting of the transmission components, when the sandpaper 6 and the sponge sheet 7 need to be closed, the handle of the pulley 8 can be rotated, and the two pulleys 8 can be driven to rotate synchronously through the transmission belt, and then the two double-sided screws 12 can be driven to rotate synchronously, causing the two pushing blocks 5 to move relative to each other.

[0030] Further, refer to Figures 1 to 3As shown in the figure, the positioning mechanism includes a hydraulic cylinder 11 disposed on the other side of the bearing gear 2, a connecting block 16 disposed above the bearing gear 2, and a plurality of curved panels 17 fixedly arranged around one end of the rod body of the connecting block 16. The outer peripheral surface of the curved panel 17 is in threaded rotational fit with a threaded rod 19. Anti-slip pads 18 are provided on the inner peripheral surfaces of the curved panels 17. The threaded rod 19 threadedly penetrates through the curved panel 17 and is in threaded connection with the threaded rod 19. The bottom surface of the hydraulic cylinder 11 is fixed to the top surface of the table 1. A cross bar 10 is horizontally arranged above the hydraulic cylinder 11. The push rod of the hydraulic cylinder 11 is fixed to one end of the cross bar 10. The other end of the cross bar 10 is fixedly connected with a pressure rod 9. The end of the pressure rod 9 is rotatably sleeved with the connecting block 16;

[0031] Through the setting of the positioning mechanism, the grinding ball is placed in the spherical groove on the top surface of the bearing gear 2. The hydraulic cylinder 11 is started, and the connecting block 16 at the end of the pressure rod 9 is driven to descend by driving the cross bar 10, and then the curved panel 17 is made to abut against the top of the wear-resistant ball to prevent the wear-resistant ball from slipping and moving. Subsequently, the threaded rod 19 is tightened, causing the anti-slip pad 18 to tightly press against the surface of the wear-resistant ball.

[0032] However, in practice, after using for a period of time, it is found that when the sandpaper 6 rubs the surface of the grinding ball, although some of the generated dust and debris are wiped by the sponge sheet 7, a part of the debris falls into the meshing part of the teeth of the bearing gear 2 and the transmission gear 3, resulting in gear jamming and damage.

[0033] In view of this, in order to solve the above problems, it is worth noting that shielding covers 15 are provided on both sides of the bearing gear 2. The side of the shielding cover 15 facing the bearing gear 2 is open. The two shielding covers 15 are fixed to the bottom surfaces of the two pushing blocks 5. The shielding covers 15 are each provided with a large semi-circular notch adapted to the grinding ball, and the shielding covers 15 are also provided with small semi-circular notches adapted to the output shaft of the motor 13.

[0034] Through the setting of the shielding covers 15, during the process of the sandpaper 6 and the sponge sheet 7 relatively closing to polish and wipe the surface of the grinding ball, the two shielding covers 15 move relatively until the two shielding covers 15 are combined, and then the bearing gear 2 and the transmission gear 3 are covered. In this way, when the sandpaper 6 polishes, the debris and dust generated by the grinding ball fall on the shielding covers 15, thus preventing the gear jamming of the bearing gear 2 and the transmission gear 3 caused by the debris.
