[0032] The following will further illustrate an automatic ball processing device and ball processing method of the present invention in conjunction with the drawings in the embodiments of the present invention.

[0033] like Figures 2 to 6The device shown is a device for automatically processing balls 2, characterized in that it includes a conveyor belt 1 for transmitting the blank 3 for processing the balls 2, two moving mechanisms, two rotating shaft motors 43, two bead nesting devices 44 and a water spraying device for spraying water to the operating station; the two moving mechanisms are erected on both sides of the width direction of the conveyor belt 1, the two moving mechanisms include two base plates 41 and guide rails 42 respectively arranged on the two base plates 41 and electric sliders relatively slidably arranged on the two guide rails 42, and the two guide rails 42 are located on the same line; the two rotating shaft motors 43 are relatively connected to the two electric sliders; the centers of the two bead nesting devices 44 are relatively arranged, the two bead nesting devices 44 are hemispherical and have equal diameters, and the ends of the bead nesting devices 44 are coaxially connected to the rotating shaft 45 of the rotating shaft motor 43; the water spraying device is erected above the conveyor belt 1 through the first support frame 6.

[0034] The shaft motor 43 drives the two shafts 45 to rotate, thereby driving the beading device 44 to rotate. The beading device is attached to the inside and grinds the blank 3. The two shaft motors 43 slide relative to each other along the guide rail 42, and the two beading devices 44 further grind the blank 3. The open ends of the two beading devices 44 gradually abut against each other, grinding the blank 3 into a spherical blank. The two shaft motors 43 move in the opposite direction, forming a gap between the two beading devices 44; the water spray device sprays high-pressure water jets into the gap, and the spherical blank rotates freely between the two beading devices 44 and continues to be polished until the spherical blank forms a regular ball 2; the two shaft motors 43 move in the opposite direction, and the ball 2 falls onto the conveyor belt 1; the conveyor belt 1 moves to process the next blank 3, and the ball 2 moves out of the operating station as the conveyor belt 1 moves.

[0035] The sliding distance and sliding speed of the shaft motor 43 and the transmission speed of the conveyor belt 1 can be set according to the actual grinding requirements. The size of the blank 3 is larger than the size of the ball 2 to be processed, and the size of the bead nest 44 is adapted to the size of the ball 2 to be processed.

[0036] The rotating shaft 45 is connected to a clamp 46 , and the clamp 46 is clamped on the bead holder 44 .

[0037] The bead holder 44 is further tightened by two clamps 46 to prevent displacement of the bead holder 44 during high-speed rotation.

[0038] The first support frame 6 includes a first support plate 62 and a first column 63 connected to the bottom of the first support plate 62; Figure 2As shown, the water spraying device includes a water pump 81, a water gun 82 for spraying water columns toward the operating station, and a water pipe 83 connected between the water outlet of the water pump 81 and the water inlet of the water gun 82. The water pump 81 is arranged above the first support plate 62, and a first through hole is opened on the first support plate 62. The water pipe 83 is passed through the first through hole, and a connecting rod 84 is connected between the water gun 82 and the lower surface of the first support plate 62.

[0039] The water gun 82 can spray low-pressure water columns and high-pressure water columns. A large amount of frictional heat is generated during the grinding ball processing process, and the frictional heat can be reduced by spraying low-pressure water columns through the water gun 82.

[0040] The second support frame 5 is further included and supported on the bottom of the two bottom plates 41 . The second support frame 5 includes a second support plate 52 for supporting the bottom plate 41 and a second column 51 connected to the bottom of the second support plate 52 .

[0041] Second through holes 11 are provided at intervals on the conveyor belt 1. The diameter of the second through holes 11 is smaller than the diameter of the ball 2. The second through holes 11 have outer edges protruding toward the upper side of the conveyor belt 1 along the circumferential direction.

[0042] After the ball 2 is processed, the two shaft motors 43 move in opposite directions, and the processed ball 2 falls into the second through hole 11 and is fixed in the second through hole 11. The ball 2 moves out of the operating station along with the movement of the conveyor belt 1. The flange serves to make the ball 2 more firmly fixed.

[0043] It also includes a first hydraulic telescopic rod 71 that presses against the upper side of the blank 3 to be processed, and a second hydraulic telescopic rod 72 that passes through the second through hole 11 and presses against the lower side of the blank 3 to be processed. The first hydraulic telescopic rod 71 is connected to the bottom of the second support plate 52, and the second hydraulic telescopic rod 72 is connected to the top of the second support plate 52.

[0044] The first hydraulic telescopic rod 71 and the second hydraulic telescopic rod 72 respectively press against the upper and lower sides of the blank 3 to be processed to prevent the blank 3 from shifting. During the processing, when the first hydraulic telescopic rod 71 and the second hydraulic telescopic rod 72 are about to contact the two bead nests 44, the hydraulic telescopic rods retract.

[0045] The present invention also provides a method for automatically processing a ball 2 using the above-mentioned device for automatically processing a ball 2, such as Figures 7 and 8 , including the following steps:

[0046] Install the ball nest 44 that matches the diameter of the ball 2 on the rotating shaft 45 of the rotating shaft motor 43;

[0047] Place the blank 3 on the conveyor belt 1, start the conveyor belt 1, and move the blank 3 between the two bead nests 44;

[0048] The shaft motor 43 and the electric slider are started to move the two shaft motors 43 toward each other. The two bead holders 44 grind the blank 3 as the shaft 45 rotates. The blank 3 is gradually ground into two hemispherical surfaces. The two shaft motors 43 continue to move toward each other until the two bead holders 44 contact each other. The blank 3 is ground into a spherical blank.

[0049] The second shaft motor 43 moves in the opposite direction, so that a gap is formed between the second bead nesting devices 44;

[0050] The water spraying device sprays high-pressure water jets into the gap, and the spherical blank rotates between the two bead nests 44 and continues to be polished until the spherical blank forms a regular ball 2;

[0051] The two rotating shaft motors 43 move in opposite directions, and the ball 2 falls onto the conveyor belt 1;

[0052] The conveyor belt 1 moves to process the next blank 3, and the ball 2 moves out of the operating station as the conveyor belt 1 moves.

[0053] The device can be used to automatically and continuously process the ball 2.

[0054] Second through holes 11 are arranged at intervals on the conveyor belt 1. The diameter of the second through holes 11 is smaller than the diameter of the ball 2. The processed ball 2 falls into the second through hole 11 and is fixed in the second through hole 11. The ball 2 moves out of the operating station as the conveyor belt 1 moves.

[0055] In order to prevent the ball 2 from rolling off the conveyor belt 1 after processing, it is preferred to open a second through hole 11 at corresponding intervals on the conveyor belt 1. After the ball 2 is processed, the two shaft motors 43 move in opposite directions, and the processed ball 2 falls into the second through hole 11 and is fixed in the second through hole 11. The ball 2 moves out of the operating station as the conveyor belt 1 moves.

[0057] 1. The present invention has a simple structure, convenient operation, low cost, and can process standardized spherical parts;

[0058] 2. The present invention effectively solves the technical problem that when turning spherical parts on a common lathe is almost finished, the parts fall off before the processing is completed, and additional clamping is difficult and inefficient when additional processing is required.
