[0027] A bolt tightening machine with intermittent feeding includes: a feeding device 1, a bearing block 2, a power member 3, a tightening device 4 and a moving device. The feeding device 1 uses an existing vibrating plate to continuously feed nuts to a discharge port 5. The discharge port 5 is docked with the side of the bearing block 2, and a groove 6 for accommodating nuts is formed at the upper end of the bearing block 2, and one side of the groove 6 is connected with the side of the bearing block 2 facing the discharge port 5. The power member 3 uses a second cylinder, and the output end of the second cylinder is fixed to the bearing block 2 by bolts, and the power member 3 pulls the bearing block 2 laterally to reciprocate between a first position and a second position. When the bearing block 2 is located at the first position, the groove 6 is docked with the discharge port 5. At this time, the nut located at the discharge port 5 enters the groove 6 under the push of the subsequent nut, and the nut entering the groove 6 provides a reaction force to the subsequent nut to prevent the subsequent nut from continuing to enter the groove 6. The power member 3 then pulls the bearing block 2 to the second position. During the movement and when the bearing block 2 reaches the second position, the side facing the discharge port 5 is docked and closes the discharge port 5 to prevent the nut in the feeding device 1 from falling from the discharge port 5. The moving device is used to move the nut in the second position to the tightening device 4 located on one side of the second position. The tightening device 4 uses an existing screw tightening machine to tighten the nut and the screw.

[0028] Specifically, the moving device includes: a picking assembly and a rotating disk 7. The picking assembly is placed on one side of the second position, and the rotating disk 7 is placed between the picking assembly and the tightening device 4. The picking assembly moves the nut at the second position to the rotating disk 7, and the worker then places other parts on the nut. The rotating disk 7 rotates intermittently to move the nut and other parts together to the tightening device 4 for tightening.

[0029] Specifically, the pickup assembly includes: a suction member 8, a transverse driving member 9 and a longitudinal driving member 10. The suction member 8 uses an existing vacuum pump, and the vacuum pump has a port for forming negative pressure. The port of the suction member 8 is installed at the output end of the longitudinal driving member 10. The longitudinal driving member 10 enables the suction member 8 to move longitudinally to suck the nut from the bearing block 2 at the height of the second position and place the nut on the rotating disk 7 at the height of the rotating disk 7. The longitudinal driving member 10 is installed at the output end of the transverse driving member 9. The transverse driving member 9 enables the longitudinal driving member 10 to move from above the second position to above the rotating disk 7 to move the nut from the bearing block 2 to the rotating disk 7 in the horizontal direction.

[0030] Specifically, the height of the second position is the same as the height of the rotating disk 7, so that the length of the port of the suction member 8 for lifting and lowering the longitudinal drive member 10 remains consistent, which is convenient for adjusting the movement of the output end of the longitudinal drive member 10 when installing the longitudinal drive member 10, thereby preventing the nut from being released from the rotating disk 7 at a height that is too high, causing the nut to bounce up and be misplaced, and preventing the output end of the longitudinal drive member 10 from interfering with the rotating disk 7 at a height that is too low, thereby causing damage to the longitudinal drive member 10 and the rotating disk 7.

[0031] Specifically, it also includes: a guide groove 11, the bearing block 2 is placed in the guide groove 11, the lower end and two opposite sides of the bearing block 2 are in contact with the guide groove 11, and the bearing block 2 slides along the guide groove 11 between the first position and the second position under the drive of the power member 3, and the guide groove 11 supports and guides the bearing block 2.

[0032] Specifically, the transverse moving part is a magnetic rail, the longitudinal driving part 10 is a first cylinder, the magnetic rail is placed on the ground, the sliding frame of the magnetic rail is connected to the shell of the first cylinder by bolts, and the output end of the first cylinder is connected to the port of the suction member 8 by bolts.

[0033] Specifically, it also includes: a flipping mechanical arm 12 and a conveyor belt 13. The flipping mechanical arm uses an existing product, which includes a clamp for grabbing the workpiece. The rotating disk 7 moves the nut from the tightening device 4 to one side of the flipping mechanical arm 12, and the clamp of the flipping mechanical arm 12 grabs the nut from the rotating disk 7 and flips it onto the conveyor belt 13, which transports it to other places for collection.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
