The main positioning moving component and the auxiliary positioning moving component are relatively installed on both sides of the width direction of the base 1. The main positioning moving component and the auxiliary positioning moving component are respectively connected to the power component for transmission. The power component drives the main positioning moving component and the auxiliary positioning moving component to move closer to or away from each other relative to the base 1 to meet the conveying and clamping positioning requirements of cable trays of different specifications. Punching components are connected to both the main positioning moving component and the auxiliary positioning moving component. The punching component moves with the main positioning moving component or the auxiliary positioning moving component in the direction close to the cable tray, thereby completing the punching operation of the cable tray.

[0028] like Figure 1 and Figure 2 As shown, the conveying assembly includes a conveying bracket 2 and several conveying rollers 3. There are two conveying brackets 2. The two conveying brackets 2 are symmetrically installed on both sides of the base 1. Several conveying rollers 3 are installed on the two conveying brackets 2 at intervals. The conveying rollers 3 can rotate relative to the conveying bracket 2 to realize the conveyance of the cable tray and reduce the friction when the cable tray moves.

[0029] like Figure 1 As shown, the power assembly includes a dual-axis motor 4, two sets of ball screw pairs 5 and two sets of linear guide pairs 6. The dual-axis motor 4 is installed on the base 1. The two sets of ball screw pairs 5 are symmetrically installed on the base 1 and are located on both sides of the dual-axis motor 4. The two sets of ball screw pairs 5 are respectively connected to the output shafts on both sides of the dual-axis motor 4. The dual-axis motor 4 drives the two sets of ball screw pairs 5 to rotate. The two sets of linear guide pairs 6 are symmetrically installed at both ends of the length direction of the base 1.

[0030] like Figure 1 and Figure 3As shown, the main positioning moving assembly includes a main positioning seat 7, a drive motor 8, a transmission shaft 9 and an active roller 10. The main positioning seat 7 is connected to two sets of linear guide pairs 6 and can move relative to the base 1 along the linear guide pairs 6. The main positioning seat 7 is connected to one set of ball screw pairs 5 for transmission, and is driven by the dual-axis motor 4 through the set of ball screw pairs 5 to achieve movement. The drive motor 8 is installed at one end of the main positioning seat 7, and the transmission shaft 9 is installed on the main positioning seat 7. The drive motor 8 is connected to the transmission shaft 9 for transmission, and the transmission shaft 9 is driven by the drive motor 8 to rotate relative to the main positioning seat 7. A first bevel gear 11 is fixedly connected to the transmission shaft 9. In this embodiment There are two active rollers 10, and the two active rollers 10 are installed on the main positioning seat 7 at an interval and can be rotated. A second bevel gear 12 is fixedly connected to the lower end of the active roller 10, and the number of first bevel gears 11 is correspondingly set to two. The two first bevel gears 11 are respectively engaged with the two second bevel gears 12 one by one. The engagement of the first bevel gear 11 and the second bevel gear 12 drives the active roller 10 to rotate. When in use, the active roller 10 is located between two adjacent conveying rollers 3, and the active roller 10 extends upward to the top of the conveying roller 3, thereby clamping and conveying the cable tray conveyed on the conveying roller 3.

[0031] like Figure 1 As shown, the auxiliary positioning moving assembly includes an auxiliary positioning seat 13 and an auxiliary roller 14. The auxiliary positioning seat 13 is connected to two groups of linear guide pairs 6 and can move relative to the base 1 along the linear guide pairs 6. The auxiliary positioning seat 13 is connected to another group of ball screw pairs 5 for transmission, and is driven by the dual-axis motor 4 through the group of ball screw pairs 5 to achieve movement. In this embodiment, the number of auxiliary rollers 14 is two, and the two auxiliary rollers 14 correspond one-to-one to the two active rollers 10.

The friction between the cable tray, the active roller 10 and the auxiliary roller 14 drives the cable tray to move, so that the position where the cable tray is to be punched is moved to the bottom of the gantry 15, the driving motor 8 stops, and the lifting cylinder 16 extends to make the air claw 18 drop to the inside of the cable tray, and the air claw 18 extends to both sides. The support plates 19 at both ends of the air claw 18 support the inner walls of the two sides of the cable tray, and the support protrusions 20 support the two sides of the punching position. The power motor 23 is started, driving the drill 27 to approach the cable tray, and the drill 27 is started to punch the side walls of the cable tray;

[0038] After the drilling is completed, the air claw 18 retracts, the power motor 23 drives the drill 27 to reset, the drive motor 8 starts, and after the cable tray moves to a certain position, the air claw 18 extends again to support the inner wall of the cable tray, and the power motor 23 drives the drill 27 to approach the cable tray again, and the drill 27 performs another drilling operation;

[0039] Repeat the above steps to complete the punching operation of the cable tray in sequence.
