Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1-5 The utility model provides a technical solution: a plate bending and positioning mechanism for a distribution cabinet, comprising a base frame 1, a base 2 is installed on the base frame 1, an electric cylinder 3 is installed in the middle position of the base 2, one end of the electric cylinder 3 is connected to a rotating seat 4, the electric cylinder 3 comprises a push rod, the push rod is fixed to the rotating seat 4, one end of the rotating seat 4 is connected to a positioning platform 5, the rotating seat 4 has a rotating motor built in, the output shaft of the rotating motor is fixed to the positioning platform 5, four groups of electric roller assemblies 6 are arranged on the positioning platform 5, and the electric roller assemblies 6 are symmetrically arranged in pairs, a connecting frame 7 is installed on one side of the upper end of the base 2, a fixing platform 8 is installed on the top of the connecting frame 7, a negative pressure driving seat 9 is arranged on the lower end surface of the fixing platform 8, and a plurality of groups of adsorption holes 10 are provided on the upper end surface of the fixing platform 8.

[0024] When the electric cylinder 3 is working, it drives the positioning platform 5 on its upper part to move axially. When the rotating motor inside the rotating seat 4 is working, it drives the positioning platform 5 to rotate relative to the fixed platform 8. When the distribution cabinet plate is placed on the fixed platform 8, the electric cylinder 3 can work to axially drive the positioning platform 5 to lift the plate, and the rotating motor can work to drive the positioning platform 5 to drive the plate to rotate.

[0025] When the vacuum pump assembly built into the negative pressure driving seat 9 is working, the multiple groups of adsorption holes 10 of the fixing platform 8 generate negative pressure adsorption force.

[0026] A through slot is provided in the middle of the fixing platform 8, and the positioning platform 5 is located in the through slot. When the positioning platform 5 moves axially, the fixing platform 8 avoids it through the through slot.

[0027] The four groups of electric roller assemblies 6 are evenly spaced along the circumferential direction of the positioning platform 5 .

[0028] Among them, the four groups of electric roller assemblies 6 all include a U-shaped frame 12, and a stepper motor 14 is installed on the outside of the U-shaped frame 12. One end of the stepper motor 14 is connected to the roller 13, and the roller 13 is connected to the U-shaped frame 12 through a bearing. When the stepper motor 14 works, it drives the roller 13 at one end thereof to rotate.

[0029] An anti-skid layer 15 is disposed on the outer side of the roller 13 to prevent the roller 13 from slipping.

[0030] Among them, two sets of parallel electric roller assemblies 6 are a set of driving components, and four sets of electric roller assemblies 6 form two sets of driving components. When the rollers 13 of one set of driving components rotate in the same direction, the rotational force is converted into a linear driving force to drive the sheet metal above it to move horizontally. When the rollers 13 of the other set of driving components rotate in the same direction, the rotational force is converted into a linear driving force to drive the sheet metal above it to move horizontally. The positions of the sheet metal in the X-axis direction and the Y-axis direction are adjusted by the four sets of electric roller assemblies 6.

[0031] Among them, a vacuum pump assembly is built in the negative pressure driving seat 9, and the vacuum pump assembly is connected to the fixed table 8 through an air pipe 11. A chamber is arranged inside the fixed table 8, and the chamber is communicated with a plurality of adsorption holes 10 and the air pipe 11. When the vacuum pump assembly works, a negative pressure adsorption force can be generated in the plurality of adsorption holes 10, and the presence or absence of the adsorption force of the plurality of adsorption holes 10 is controlled by the vacuum pump assembly.

[0032] Among them, when bending, the negative pressure driving seat 9 works to generate a negative pressure adsorption force in the plurality of adsorption holes 10, and the sheet metal is adsorbed and fixed by relying on this negative pressure adsorption force, so that the sheet metal remains stable during the bending process, preventing the sheet metal from slipping and displacing, and improving the bending stability.

[0033] Among them, after the bending of one side edge of the sheet metal is completed, the negative pressure adsorption force is released, the electric cylinder 3 works to axially drive the positioning table 5 to lift the sheet metal, the rotating motor works to drive the positioning table 5 to drive the sheet metal to rotate, and the electric roller assembly 6 works to adjust the horizontal position of the sheet metal. Through the lifting, turning and horizontal displacement of the sheet metal, the next set of edges to be bent of the sheet metal is moved to the bending position. Then the electric cylinder 3 works to drive the positioning table 5 to move down, and the sheet metal is placed on the fixed table 8 again, and the adsorption holes 10 generate a negative pressure adsorption force to fix the sheet metal again, realizing automatic bending positioning of the sheet metal without manual operation, saving time and effort.

[0034] Among them, first notches 16 are formed on both side surfaces of the chassis 1, second notches 17 are formed on both side surfaces of the base 2, the chassis 1 and the base 2 are fixed by bolts, and the chassis 1 and the base 2 are of a detachable structure. The height position of the base 2 relative to the chassis 1 is adjustable. By adjusting the installation position of the base 2, the height position of the overall bending positioning mechanism is adjusted to make the bending positioning mechanism match the bending machine.

[0035] Among them, a power supply chassis 18 is arranged on the chassis 1 to provide power support for the overall bending positioning mechanism.

[0036] Among them, feet 19 are arranged on both sides at the lower end of the chassis 1 to fix the overall bending positioning mechanism through the feet 19.

[0037] Working principle: During use, the height position of the overall bending positioning mechanism is adjusted by adjusting the installation position of the base 2 to make the bending positioning mechanism adapt to the bending machine. When bending, the sheet is placed on the fixed table 8, and one side of the sheet is located at the bending processing position. The vacuum pump assembly inside the negative pressure driving seat 9 works to make multiple adsorption holes 10 generate negative pressure adsorption force. The fixed table 8 adsorbs and fixes the sheet by relying on this negative pressure adsorption force to keep the sheet stable during bending processing. After one side of the sheet is bent and processed, the negative pressure adsorption force is released, the electric cylinder 3 works to axially drive the positioning table 5 to lift the sheet, and the rotating motor works to drive the positioning table 5 to drive the sheet to rotate, rotating the sheet. The electric roller assembly 6 works to adjust the horizontal position of the sheet. Through the lifting, turning and horizontal displacement of the sheet, the next group of edges of the sheet to be bent is moved to the bending processing position. Then the electric cylinder 3 works to drive the positioning table 5 to move down, place the sheet on the fixed table 8 again, the adsorption holes 10 generate negative pressure adsorption force, and fix the sheet again, realizing automatic bending positioning of the sheet.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
