By contracting the telescopic end of the hydraulic cylinder, a pulling force can be applied to the sliding sleeve at the bottom of the power source, so that the power source drives the tapping cylinder and the bent pushing rod to move toward the direction of the bolt blank. The bent end of the bent pushing rod is embedded in the interior of the wedge-shaped groove, so that the bent end of the bent pushing rod applies a downward pressing force to the dovetail-shaped pressing block, and under the sliding guidance of the guide square column, the dovetail-shaped pressing block moves downward, the reset spring is compressed, and the bolt clamping groove is clamped on the top of the bolt blank, so that the bolt blank can be fixed, and it is not easy to deviate or skew.

[0012] As the bolt blanks fall under their own gravity, the opening of the storage trough gradually decreases from top to bottom, so that the bolt blanks can be arranged one by one at the discharge port at the bottom of the storage trough, and the two symmetrical planes of the hexagonal nut head of the bolt blank fit with the inner wall of the guide sleeve, so that the bolt blanks can be guided and move downward in an orderly manner.

[0015] As the feeding disc rotates counterclockwise, the bolt limiting groove is driven to rotate counterclockwise, and rotates through the bolt limiting groove to just below the discharge port at the bottom of the storage trough, so that the bolt blank falls into the bolt limiting groove. Combined with the discharge port at the bottom of the storage trough and the notch on the side close to the camera, the bolt blank embedded in the bolt limiting groove is smoothly brought out, so that loading can be carried out, and the remaining bolt blanks are still arranged in order at the position of the discharge port of the storage trough, which is convenient for subsequent continuous loading.

The bolt blanks are arranged one by one at the discharge port at the bottom of the storage trough, and the two symmetrical planes of the hexagonal nut heads of the bolt blanks fit into the inner wall of the guide sleeve to guide the bolt blanks; Step 3: Turn on the feeding disc and rotate it counterclockwise to drive the anti-skid ring to rotate. The friction force of the anti-skid ring on the round wheel drives the tapping wheel to rotate clockwise, and the tapping wheel taps the bolt blank. Step 4: The feeding disc drives the bolt limiting groove to rotate to the bottom of the storage trough just below the discharge port, and the bolt blank falls into the bolt limiting groove, so that the bolt blank embedded in the bolt limiting groove is smoothly brought out for loading; Step 5: The position of the bolt blank is photographed and collected by the camera, and the collected information is transmitted to the controller. The controller receives and processes the information, and the manipulator adjusts the position of the bolt blank inside the bolt limit slot that is in disorder; Step 6: When the bolt blank moves to the bottom of the dovetail-shaped pressing block, the feeding disc is stopped and the hydraulic cylinder is turned on. The telescopic end of the hydraulic cylinder is contracted, so that the power source drives the tapping cylinder and the bent pushing rod to move toward the bolt blank. The bent pushing rod is used to apply downward pressure to the dovetail-shaped pressing block, so that the dovetail-shaped pressing block moves downward, and the bolt clamping groove is clamped on the top of the bolt blank to fix the bolt blank. Step 7: Turn on the power source to work, use the output end of the power source to drive the tapping cylinder to rotate, and as the power source drives the tapping cylinder to continuously move toward the bolt blank, tap the end of the bolt blank; Step 8: When the bolt is tapped, the tapping barrel is driven to rotate in the opposite direction through the output end of the power source, and the telescopic end of the hydraulic cylinder is extended, so that the thread can be withdrawn, and the pressing force of the bent push rod on the dovetail pressing block disappears, causing the dovetail pressing block to move upward, and the pressing force on the bolt disappears. The feeding disc is turned on again to rotate, the bolt is moved out, and the bolt is removed by the manipulator.

[0018] The beneficial effects of the embodiments of the present invention are: 1. The tapping machine and method for bolt processing utilize the rotation of the output end of the power source to drive the tapping cylinder to rotate. As the power source drives the tapping cylinder to continuously move toward the bolt blank, the end of the bolt blank can be tapped. The waste chips generated during tapping come into contact with the inner wall of the semicircular notch, instantly changing the extrusion direction of the waste chips, thereby breaking the chips. It is not easy for the waste chips to be entangled, and the waste chips can be effectively prevented from scratching the bolt.

[0019] Second, the tapping machine and method for processing bolts utilizes the surface of the tapping barrel to evenly open V-shaped openings to facilitate the discharge of waste chips generated by tapping, making chip removal convenient and less likely to cause chip accumulation.

[0021] Fourth, the tapping machine and method for processing bolts, as the bolt blanks fall under their own gravity and the opening of the storage trough gradually decreases from top to bottom, the bolt blanks can be arranged one by one at the discharge port at the bottom of the storage trough, and the two symmetrical planes of the hexagonal nut heads of the bolt blanks are fitted with the inner wall of the guide sleeve, so that the bolt blanks can be guided and moved downward in an orderly manner.

[0022] 5. The tapping machine and method for processing bolts utilizes the counterclockwise rotation of the feeding disc to drive the anti-skid ring to rotate, and utilizes the outer cylindrical surface of the circular wheel to contact the top of the anti-skid ring to increase the friction between the circular wheel and the anti-skid ring, so that the circular wheel can be driven to roll clockwise, and connected to the rotating shaft at the center of the tapping wheel, so that the tapping wheel is driven to rotate clockwise, and the rolling direction of the tapping wheel can be opposite to the falling direction of the bolt blank in the storage trough. The tapping wheel taps the bolt blank, so that the bolt blank in the storage trough is always in motion, further promoting the orderly dropping of the bolt blank, and less likely to cause material accumulation and jamming.

[0023] 6. The tapping machine and method for bolt processing rotates through the bolt limiting groove to the bottom of the storage trough just below the discharge port, so that the bolt blank falls into the interior of the bolt limiting groove, and is combined with the discharge port at the bottom of the storage trough and the side close to the camera is a notch, so that the bolt blank embedded in the bolt limiting groove is smoothly brought out, thereby loading, and the remaining bolt blanks are still arranged in order at the position of the storage trough discharge port, which is convenient for subsequent continuous loading.

[0024] 7. The tapping machine and method for bolt processing uses a camera to capture information about the position of the bolt blank and transmit the information collected by the camera to a controller. The controller receives and processes the information and can adjust the position of the bolt blank inside the bolt limit groove with a disordered position through an external manipulator, and fine-tune the position of the bolt blank to make the position of the bolt blank more accurate, which is helpful for subsequent tapping.

[0025] 8. The tapping machine and method for processing bolts utilizes the bent end of the bent pushing rod to be embedded in the interior of the wedge-shaped groove, so that the bent end of the bent pushing rod applies downward pressing force to the dovetail-shaped pressing block, and under the sliding guidance of the guide square column, the dovetail-shaped pressing block moves downward, the reset spring is compressed, and the bolt clamping groove is clamped on the top of the bolt blank, so that the bolt blank can be fixed and is not prone to deviation and skew.

As the power source 42 drives the tapping cylinder 44 to continue to move toward the bolt blank, the end of the bolt blank can be tapped, and the waste chips generated during tapping come into contact with the inner wall of the semicircular notch 46, instantly changing the extrusion direction of the waste chips, so that the chips can be broken, and the waste chips are not easily entangled, effectively preventing the waste chips from scratching the bolts, and the surface of the tapping cylinder 44 is evenly provided with V-shaped openings 45 to facilitate the discharge of waste chips generated by tapping.

The controller 2 receives and processes the information, and the manipulator adjusts the position of the bolt blank inside the bolt limiting groove 33 that is in disorder; Step 6: When the bolt blank moves to the bottom of the dovetail-shaped pressing block 326, the feeding disc 31 is stopped and the hydraulic cylinder 43 is turned on. The telescopic end of the hydraulic cylinder 43 contracts, so that the power source 42 drives the tapping cylinder 44 and the bent pushing rod 47 to move toward the bolt blank.

[0044] The storage trough 52 and the bent clamping plate 53 are tapered as a whole, and the opening of the storage trough 52 gradually decreases from top to bottom. There are two brackets 51, and the two brackets 51 are symmetrically installed along the storage trough 52. The staff starts the feeding disc 31 to work, and uses the feeding disc 31 to rotate counterclockwise, which can drive the anti-skid ring 34 to rotate, and uses the outer cylindrical surface of the circular wheel 57 to contact the top of the anti-skid ring 34, so that the friction between the circular wheel 57 and the anti-skid ring 34 is increased, and the circular wheel 57 can be driven to roll clockwise, and connected to the rotating shaft at the center of the tapping wheel 56, so that the tapping wheel 56 is driven to rotate clockwise, and the rolling direction of the tapping wheel 56 can be opposite to the falling direction of the bolt blanks in the storage trough 52. The tapping wheel 56 taps the bolt blanks, and the bolt blanks in the storage trough 52 are always in motion.

[0045] The guide sleeve 54 is installed directly below the bent clamping plate 53, and the circular wheel 57 and the tapping wheel 56 are installed at the same height. The surface of the tapping wheel 56 is embedded in the interior of the storage trough 52. As the feeding disc 31 rotates counterclockwise, the bolt limiting groove 33 is driven to rotate counterclockwise, and rotates to the bottom of the storage trough 52 through the bolt limiting groove 33. It rotates to the bottom of the storage trough 52 and the side close to the camera 55 is a notch, so that the bolt blank embedded in the bolt limiting groove 33 is smoothly brought out, so that loading can be carried out, and the remaining bolt blanks are still arranged in order at the position of the storage trough 52 outlet.

[0046] During use, the bolt blanks to be tapped are first placed inside the storage trough 52, the bolt blanks are stored, and the hexagonal nut heads of the bolt blanks are embedded between the edge of the storage trough 52 and the inner side of the bent clamping plate 53, the bolt blanks are clamped, and the bolt blanks fall under their own gravity, and the opening of the storage trough 52 gradually decreases from top to bottom. The bolt blanks are arranged one by one at the discharge port at the bottom of the storage trough 52, and the two symmetrical planes of the hexagonal nut heads of the bolt blanks are in contact with the inner wall of the guide sleeve 54 to guide the bolt blanks; At this time, the feeding disc 31 is turned on and rotated counterclockwise, driving the anti-skid ring 34 to rotate, and the circular wheel 57 is subjected to the friction force of the anti-skid ring 34, so that the circular wheel 57 drives the paddle wheel 56 to rotate clockwise, and the paddle wheel 56 pokes the bolt blank. The feeding disc 31 is turned on and rotated counterclockwise, driving the anti-skid ring 34 to rotate, and the circular wheel 57 is subjected to the friction force of the anti-skid ring 34, so that the circular wheel 57 drives the paddle wheel 56 to rotate clockwise, and the paddle wheel 56 pokes the bolt blank. The feeding disc 31 drives the bolt limiting groove 33 to rotate to the bottom of the material storage trough 52, and the bolt blank falls into the bolt limiting groove 33, so that the bolt blank embedded in the bolt limiting groove 33 is smoothly taken out for loading. The position of the bolt blank is photographed and collected by the camera 55, and the collected information is transmitted to the controller 2. The controller 2 receives and processes the information, and the manipulator adjusts the position of the bolt blank inside the bolt limiting groove 33 that is in a disordered position; When the bolt blank moves to the bottom of the dovetail pressing block 326, the feeding disc 31 is stopped and the hydraulic cylinder 43 is turned on. The contraction of the telescopic end of the hydraulic cylinder 43 is used to make the power source 42 drive the tapping cylinder 44 and the bent pushing rod 47 to move toward the bolt blank. The bent pushing rod 47 applies a downward pressing force to the dovetail pressing block 326, so that the dovetail pressing block 326 moves downward. The bolt clamping groove 328 is clamped on the top of the bolt blank to fix the bolt blank. The power source 42 is turned on to work, and the output end of the power source 42 is used to drive the tapping cylinder 44 to rotate. As the power source 42 drives the tapping cylinder 44 to continue to move toward the bolt blank, the end of the bolt blank is tapped. Moreover, when the tapping of the bolt is completed, the tapping cylinder 44 is driven to rotate in the opposite direction through the output end of the power source 42, and the telescopic end of the hydraulic cylinder 43 is extended, so that the thread can be withdrawn, and the pressing force of the bent pushing rod 47 on the dovetail pressing block 326 disappears, causing the dovetail pressing block 326 to move upward, and the pressing force on the bolt disappears, and the feeding disc 31 is opened again to rotate, the bolt is moved out, and the bolt is removed by the robot.
