When working, when processing the distribution cabinet, when processing the cabinet door, it is necessary to open the cabinet door so that an indicator light or a switch, etc. can be installed on the cabinet door. In order to meet the opening operations of various apertures, the adjusting screw rod 103 is adjusted and rotated by a cross screwdriver. When the adjusting screw rod 103 rotates, the two tool slides 102 are driven to expand or contract synchronously. After the two tool slides 102 slide along the limit rod 105, the distance between the cutting knives 106 on the two tool slides 102 is the opening diameter.

When adjusting the rear opening diameter, the moving cylinder 6 works to push the movable plate 4 to slide downward. The punching motor 7 can slide downward, and when the punching motor 7 rotates, it can drive the punching structure 10 to rotate. During the rotation, the cutting knife 106 is used to rotate and cut, so as to cut the distribution cabinet door.

A first spring 18 is fixedly connected between the middle side wall of the movable push plate 21 and the inner wall of the rotating cylinder 17.

[0046] After the hole is opened, there will still be burrs on the edge of the opening. In order to achieve better installation standards, after the opening is completed, the ring is generally polished with sandpaper to clean the burrs. In order to improve the processing effect, after the hole is opened, the telescopic cylinder 13 pushes the triangular push plate 12 downward to operate. The downward operation of the triangular push plate 12 is divided into two processes:

[0047] 1) After the triangular push plate 12 contacts the top of the movable push plate 21, the two movable push plates 21 are tightly attached to each other under the expansion force of the first spring 18. When the triangular push plate 12 pushes the movable push plate 21 downward in the initial stage, the entire rotating cylinder 17 is driven to move downward, and the grinding block 19 that was originally parallel to the bottom side of the mounting plate 101 is pushed out to a position lower than the bottom side of the mounting plate 101. During the pushing process, the spring 15 is compressed. After the spring 15 is compressed.

[0048] 2) After the spring 15 is compressed, the position of the rotating cylinder 17 will no longer change. At this time, the triangular push plate 12 continues to push down, which can push the movable push plate 21 to both sides, thereby compressing the first spring 18. When the movable push plate 21 moves to both sides, the grinding block 19 is pushed to contact the inner wall of the cutting aperture through the cooperation of the telescopic rod 20, and the aperture is polished under the rotation cooperation.

[0049] Through the above two operation processes, the extension and expansion of the grinding structure can be realized, the rotary grinding can be realized through the cooperation of the grinding block 19, the integrated hole opening operation can be realized, and when grinding, the same hole diameter can be ground to reduce the amount of wear, the hole opening is more standardized, and the cabinet door processing quality can be improved.

[0050] A trigger structure 11 is fixed on the top side of the mounting plate 101, a connecting plate 14 is fixed on the trigger structure 11, a telescopic cylinder 13 is mounted in the middle position of the top side of the connecting plate 14, an inverted triangular push plate 12 is arranged at the bottom end of the action rod of the telescopic cylinder 13, and the middle low point of the triangular push plate 12 is arranged between the two movable push plates 21.

[0051] See also Figure 7As shown, a trigger structure 2 is provided on the side of the mounting plate 101, and the trigger structure 2 includes a fixed plate 111, a socket is provided in the fixed plate 111, and a movable rod 115 is slidably inserted in the socket, a support plate 113 is installed on the top of the movable rod 115, and the support plate 113 is located above the fixed plate 111, and a second spring 112 is fixedly connected between the support plate 113 and the fixed plate 111, and a trigger plate 116 is fixed to the bottom end of the movable rod 115, and a first electrode plate 117 is fixed to the middle of the movable rod 115, and the first electrode plate 117 is located below the fixed plate 111, and a second electrode plate 118 is fixed to the bottom port position of the socket, and the first electrode plate 117, the second electrode plate 118 and the warning light 114 are connected in series, in order to be able to realize after the hole is opened , accurately cooperate to grind the aperture burrs. When drilling a hole, since the bottom of the cutting knife 106 contacts the board surface, it moves downward with the rotation of the cutting knife 106 to realize the drilling operation. Before and after drilling a hole, the bottom side of the mounting plate 101 is at different distances from the cabinet door board surface. Before drilling a hole, the trigger plate 116 contacts the board surface, and the first electrode plate 117 and the second electrode plate 118 are in a separated state. After the drilling is completed, the mounting plate 101 contacts the board surface to push up and squeeze the trigger plate 116, so that the first electrode plate 117 and the second electrode plate 118 are in contact, and the warning light 114 can be powered on. The power-on signal of the warning light 114 is sent to the control box 5 with the cooperation of the signal generator 120. The control box 5 issues an operation instruction to the telescopic cylinder 13, which can realize the grinding operation after drilling and ensure the continuity of the operation.

[0052] A storage battery 119 and a signal generator 120 are installed on the top side of the mounting plate 101 . The storage battery 119 provides a power source for the warning light 114 and the telescopic cylinder 13 . The signal generator 120 is used to receive a control signal from the control box 5 . At the same time, the signal generator 120 receives a flashing signal from the warning light 114 .

[0053] A method for processing a power distribution cabinet comprises the following steps:

[0054] S1: Determine the punching position: calibrate the position of the mounting holes on the plate and detect the flatness of the plate.

[0055] S2: Setting the punching position and punching depth of the tool: According to the thickness of the plate, the cutting depth of the cutting knife 106 is adjusted, and at the same time, the distance between the cutting knife 106 and the axis of the punching motor 7 is adjusted to set the hole diameter.

[0056] S3: Mark the punching position: Place the punching plate on the surface of the punching bracket 1, determine the flatness of the plate, and use a flatness detector to detect the flatness of the plate. The thickness difference of the flatness is 0-3mm. Align the punching position set in S1 with the operating position of the punching structure 10.

[0057] S4: Punching operation: After the plate is placed, the punching structure 10 moves downward to perform punching and cutting operations on the plate.

[0058] S5: Grinding operation: After the drilling is completed, after the grinding block 19 is expanded, the inner wall and edge of the hole can be ground and trimmed by rotation.

[0059] S6: Material separation: After completing the drilling and grinding, the next drilling operation is carried out, and the waste material is discharged through the material guide trough 2.

[0060] Working principle: In order to meet the opening operations of various apertures, the rotating adjustment screw 103 is adjusted by a cross screwdriver. When the adjustment screw 103 rotates, the two tool slides 102 are driven to expand or contract synchronously. After the two tool slides 102 slide along the limit rod 105, the distance between the cutting knives 106 on the two tool slides 102 is the opening diameter.

[0061] When adjusting the rear opening diameter, the moving cylinder 6 operates to push the movable plate 4 to slide downward, so that the punching motor 7 can slide downward. When the punching motor 7 rotates, it can drive the punching structure 10 to rotate. During the rotation, the cutting knife 106 is used to rotate and cut, so as to achieve the cutting of the distribution cabinet door. The adjustment of the cabinet door with different apertures can be achieved by adjusting the distance between the two cutting knives 106, which reduces the steps of replacing the blade head. The aperture adjustment of the cabinet door mounting hole can be achieved through simple adjustment, and there is no need for reciprocating calibration after the blade head is replaced. At the same time, the force on the opening is reduced, which can ensure that the cabinet door will not bend excessively during the opening process, and the opening effect can be better guaranteed.

[0062] After the hole is opened, the telescopic cylinder 13 pushes the triangular push plate 12 downward to operate. The downward operation of the triangular push plate 12 is divided into two processes:

[0063] 1) After the triangular push plate 12 contacts the top of the movable push plate 21, the two movable push plates 21 are tightly attached to each other under the expansion force of the first spring 18. When the triangular push plate 12 pushes the movable push plate 21 downward in the initial stage, the entire rotating cylinder 17 is driven to move downward, and the grinding block 19 that was originally parallel to the bottom side of the mounting plate 101 is pushed out to a position lower than the bottom side of the mounting plate 101. During the pushing process, the spring 15 is compressed. After the spring 15 is compressed.

[0064] 2) After the spring 15 is compressed, the position of the rotating cylinder 17 will no longer change. At this time, the triangular push plate 12 continues to push down, which can push the movable push plate 21 to both sides, thereby compressing the first spring 18. When the movable push plate 21 moves to both sides, the grinding block 19 is pushed to contact the inner wall of the cutting aperture through the cooperation of the telescopic rod 20, and the aperture is polished under the rotation cooperation.

[0065] Before and after drilling, the bottom side of the mounting plate 101 has a different distance from the cabinet door panel surface. Before drilling the hole, the trigger plate 116 contacts the panel surface, and the first electrode plate 117 and the second electrode plate 118 are in a separated state. After the hole is drilled, the mounting plate 101 contacts the panel surface to push up and squeeze the trigger plate 116, so that the first electrode plate 117 and the second electrode plate 118 are in contact, and the warning light 114 can be powered on. The power-on signal of the warning light 114 is sent to the control box 5 with the cooperation of the signal generator 120. The control box 5 sends an operation instruction to the telescopic cylinder 13, which can realize the grinding operation after drilling and ensure the continuity of the operation.

[0066] Through the above two operation processes, the extension and expansion of the grinding structure can be realized, the rotary grinding can be realized through the cooperation of the grinding block 19, the integrated hole opening operation can be realized, and when grinding, the same hole diameter can be ground to reduce the amount of wear, the hole opening is more standardized, and the cabinet door processing quality can be improved.
