The invention provides a punching method of an aluminum alloy bridge frame punching device for a half-space operation, which comprises the following steps:

(1) Placing an aluminum alloy bridge 12 to be punched on the mounting frame 1, connecting the aluminum alloy bridge 12 with the boss 11, starting the air cylinder 43, pushing the punching motor and the drill bit 44 to be close to the aluminum alloy bridge 12 through the extending end of the air cylinder 43, and enabling the punching motor to drive the drill bit 44 to rotate so that the drill bit 44 punches the aluminum alloy bridge 12;

(2) After the drill bit 44 completes punching a position on the aluminum alloy bridge 12, starting a first power source, enabling the first power source to drive the rotating rod 3 to rotate so that the rotating rod 3 pushes the first pull rod 4, driving the moving plate 7 and the cylindrical deflector rod 8 to lift through a sliding block III connected with the first pull rod 4, and finally pushing the boss 11 through the cylindrical deflector rod 8 to complete transposition of the aluminum alloy bridge 12;

(3) When the aluminum alloy bridge 12 is transposed, the driving part is driven to move by the second power source, so that the driving part drives the sliding rod 24 to move, and at the moment, the clamping plate 25 on the sliding rod 24 drives the adsorption wheel 26 to move, so that the adsorption wheel 26 can adsorb scraps on the aluminum alloy bridge 12.

The working principle is that an aluminum alloy bridge 12 to be perforated is placed on a mounting frame 1, and then a boss 11 and the aluminum alloy bridge 12 are connected together through a sucker, so that the aluminum alloy bridge 12 and the boss 11 can move on the mounting frame 1 simultaneously when the boss 11 slides on the mounting frame 1.

After the aluminum alloy bridge 12 and the boss 11 are connected, an air cylinder 43 fixedly installed on the installation table 42 is started, and the punching motor and the drill bit 44 are pushed to move on the installation table 42 through the extending end of the air cylinder 43, so that the drill bit 44 is close to the aluminum alloy bridge 12, after the drill bit 44 contacts the aluminum alloy bridge 12, the punching motor is started, and the punching motor drives the drill bit 44 to rotate, so that punching of the aluminum alloy bridge 12 is completed. After punching of one location is completed, the aluminum alloy bridge 12 needs to be advanced one station to continue punching of the next location.

Specifically, the first motor 2 fixedly installed on the U-shaped frame 13 is started, the output shaft of the first motor 2 rotates, the rotating rod 3 fixedly connected to the output shaft of the first motor 2 rotates at this time, the rotating rod 3 drives the first pull rod 4 to move, so that one third slide block connected with the first pull rod 4 can slide on the guide rail 5 in a reciprocating manner, and the other third slide block can slide on the other guide rail 5 in a reciprocating manner under the action of the cross rod 6. In the initial state, when the motor I2 drives the rotating rod 3 to rotate, the rotating rod 3 pushes the pull rod I4, so that the pull rod I4 drives the sliding blocks III to move upwards right (based on the view angle of fig. 2), and the transverse rod 6 plays a role in transmitting power to connect the two sliding blocks III together. The slider III moving rightward and upward pushes the connecting frame 45, thereby driving the moving plate 7 and the cylindrical shift lever 8 to move. It should be noted that, since the movement of the third slider is upward and rightward, the movement directions of the connecting frame 45 and the moving plate 7 both include upward directions and rightward directions, so that the cylindrical shift lever 8 fixedly mounted on the moving plate 7 pushes the boss 11 rightward, so that the boss 11 drives the aluminum alloy bridge 12 to slide rightward along the mounting frame 1, and intermittent adjustment of the processing station on the aluminum alloy bridge 12 is completed. Of course, in order to make the cylindrical shift lever 8 push the boss 11 more smoothly, an inclined plane may be provided below the boss 11, so that the cylindrical shift lever 8 is more convenient to push the boss 11, but this does not mean that the cylindrical shift lever 8 in the present embodiment cannot push the boss 11 smoothly, because the cylindrical shift lever 8 includes both the upward and rightward states, and when the cylindrical shift lever 8 is located above the lower end surface of the boss 11, the cylindrical shift lever 8 can still push the boss 11. In addition, in order to protect the contact surface of the aluminum alloy bridge 12 and the mounting frame 1, a flexible pad can be paved on the mounting frame 1 to prevent the surface of the aluminum alloy bridge 12 from being scratched.

The output shaft of the motor I2 rotates, so the sliding block III is driven to ascend and descend by the reciprocating of the rotating rod 3, namely, the moving plate 7 and the cylindrical deflector rod 8 can ascend and descend in a reciprocating mode. When the moving plate 7 and the cylindrical deflector rod 8 ascend, the photoelectric switch II 10 detects signals and controls the motor II 14 to start through the control center, and when the moving plate 7 and the cylindrical deflector rod 8 descend, the photoelectric switch I9 detects signals and controls the motor II 14 to stop through the control center.

When the motor II 14 fixedly mounted on the motor seat 23 is started, the cylindrical gear I16 fixedly connected to the output shaft of the motor II 14 rotates, at this time, the rack I17 meshed with the cylindrical gear I16 drives the slide block I18 to slide upwards along the vertical frame 15 (according to the view angle of fig. 6), at this time, the cylindrical gear II 19 is not in contact with the rack II 21, but the push-pull rod 22 pushes the slide rod 24 rightwards due to the lifting of the slide block I18, so that the slide rod 24 slides along the horizontal groove 28, at this time, the clamping plate 25 on the slide rod 24 drives the adsorption wheel 26 to roll on the inner groove of the aluminum alloy bridge 12, and therefore scraps in the inner groove of the aluminum alloy bridge 12 adhere to the surface of cotton cloth.

When the second cylindrical gear 19 is lifted to be in contact with the second rack 21, the second cylindrical gear 19 rotates under the guide of the second rack 21 because the second rack 21 is fixed, the second cylindrical gear 19 is meshed with the third cylindrical gear 20, at this time, the third cylindrical gear 20 rotates, so that the push-pull rod 22 fixedly connected with the third cylindrical gear 20 rotates to the side close to the vertical frame 15, at this time, the push-pull rod 22 pulls the sliding rod 24, so that the sliding rod 24 slides from the horizontal groove 28 in the guide plate 27 to the side close to the inclined groove 29 and finally slides to the highest position of the inclined groove 29, and because the inclined groove 29 is in an inclined state, the horizontal groove 28 is in a horizontal state, at this time, the heights of the sliding rod 24, the clamping plate 25 and the adsorption wheel 26 are increased, that is, and the adsorption wheel 26 is separated from the inner groove of the aluminum alloy bridge 12.

In the process of sliding the sliding rod 24 onto the inclined groove 29, the sliding rod 24 drives the rotating rod 33 to rise, the rotating rod 33 pulls the second slider 30 to slide along the optical axis 31, and the second pull rod 38 connected to the second slider 30 pulls the horizontal rack 39 and the storage box 40 to slide to a side close to the vertical rack 15. In addition, since the end of the rotating rod 33 connected to the sliding rod 24 is raised, the driving rod 34 connected to the rotating rod 33 is rotated clockwise (based on the view angle of fig. 10) on the placing frame 37, so that the driving rod 34 presses down the connecting rod 35, the connecting rod 35 drives the cutting knife 36 to slide downward, the cutting knife 36 cuts the cotton cloth on the raised suction wheel 26, the outermost layer of the cotton cloth sucked with the scraps is cut off, and the cotton cloth falls into the sliding storage box 40, and collection is completed. Then, as the motor two 14 is reversed, the suction wheel 26 is lowered again to return, and the storage box 40 is also returned. And after the photoelectric switch 9 detects that the moving plate 7 descends, the motor 14 stops moving, which represents that the punching of one position is finished and the cleaning of waste scraps is finished.
