It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. In my country, more than 90% of the main lines leading to the floors of power distribution rooms in buildings with more than 12 floors use bus ducts.

[0003] Currently, the bus duct is cut on site according to the actual situation. The bus duct is not polished when it is cut on site for ease of use. However, in order to make the product quality better and meet the product standards during mass production in the factory, the cut edges often need to be polished after the bus duct is cut. Currently, cutting and edging require two processes. After cutting, the product is conveyed to the next process via a conveyor belt, and manual angle adjustment and edging of the cut surface are required. The process is cumbersome, the equipment occupies a large area, and labor is consumed, resulting in high labor costs. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The following describes an embodiment of the present invention based on its overall structure. Example 1:

A U-shaped gantry 10 is installed on the device body 1. An electric cylinder 11 is installed at the middle top position of the gantry 10. The output end of the electric cylinder 11 is installed with a second motor 13 through a bracket. The output end of the second motor 13 is installed with a grinding sheet 12. The electric cylinder 11, the second motor 13 and the grinding sheet 12 constitute a grinding assembly. The grinding assembly can grind the cut edges and process some edge burrs, thereby combining the two processes into one, reducing one conveyor belt, and reducing production costs and labor costs.

[0034] See also Figure 1 Two sets of oppositely arranged tracks 2 are installed on one side of the top of the device body 1. The two sets of tracks 2 are parallel to each other. Linear motors 3 are installed on the tracks 2. Mounting seats 4 are connected between the linear motors 3. The two sets of tracks 2 can maintain the smooth sliding of the mounting seats 4, improve the flexibility of the mounting seats 4, and facilitate workers to operate.

[0035] See also Figure 1 A tool holder 5 is fixed in the middle of the top of the mounting seat 4, and a cutting knife 6 is installed on the tool holder 5. The height of the cutting knife 6 is greater than the height of the bus duct seat 7. A motor is installed on the tool holder 5, and the output end of the motor is connected to the cutting knife 6. Since the cutting knife 6 cuts the bus duct at the front end, the cutting burrs tend to protrude to the side away from the cutting knife 6. The direction of the grinding sheet 12 is consistent with the direction of the gantry 10. Therefore, the grinding sheet 12 can grind the burr surface of the bus duct. The tool holder 5 can install the cutting knife 6 and the driving source to improve the cutting stability. The tool holder 5 is made of stainless steel with high strength and long service life.

[0036] Example 2:

A fixed plate 72 is fixed to one side of the top of the busbar trough seat 7. Start the first motor 9, and the first motor 9 drives the screw rod 91 to rotate. Under the action of the wire hole at the bottom of the movable plate 71, the movable plate 71 approaches the fixed plate 72, gradually clamping the busbar trough, with good supporting effect, thereby improving the stability of the busbar trough.

[0038] See also Figure 1 、 Figure 2 A lifting seat 8 is fixed to one side of the busbar slot seat 7, and a first motor 9 is installed on the lifting seat 8. There are two busbar slot seats 7, and the two busbar slot seats 7 are mirrored along the width center line of the device body 1. A screw rod 91 is installed at the output end of the first motor 9, and a wire hole is opened on the movable plate 71 located in the limiting groove 73. The wire hole is threadedly connected to the screw rod 91. The lifting seat 8 can raise the height of the first motor 9, so that the height of the first motor 9 is adapted to the height of the wire hole at the bottom of the movable plate 71, so that the screw rod 91 can pass through the wire hole for easy installation.

[0039] See also Figure 1 The two surfaces where the device body 1 is connected to the gantry 10 are provided with movable rails. The movable rails are used to adjust the position of the gantry 10. The gantry 10 is made of stainless steel. The gantry 10 can adjust its position on the device body 1 through the movable rails to adapt to bus ducts of different thicknesses. At the same time, the gantry 10 has a stable structure, which reduces the vibration of the power parts during movement.

[0040] The implementation principle of the present utility model is as follows: first, the device body 1 is installed and the power is turned on. The worker places the bus duct on the bus duct seat 7 and places the cutting position in the middle position of the two bus duct seats. Then, the first motor 9 is started. The first motor 9 drives the screw rod 91 to rotate. Under the action of the wire hole at the bottom of the movable plate 71, the movable plate 71 approaches the fixed plate 72, and the bus duct is gradually clamped. Then, the linear motor 3 is started. The linear motor 3 drives the mounting seat 4 to move, thereby driving the tool holder 5 and the cutting knife 6 to cut the bus duct. After the cutting is completed, the position of the gantry 10 is adjusted, and the electric cylinder 11 is started to lower the grinding plate 12. The second motor 13 is started, and the second motor 13 drives the grinding plate 12 to grind the cutting edge.
