[0034] Working principle:

[0035] Place the upper part of the support plate on the top of the first seat block 3 and make the two bumps located on the lower side of the support plate respectively embed into the two right-angled notches 301. At the same time, make the arc surface of the support plate fit on the arc-shaped positioning surface 302. Then embed the lower part of the support plate into the first U-shaped bracket 23 and the second U-shaped bracket 13 and make the lower end of the support plate press against the bottom bracket 24. At this time, the upper end of the support plate is located between the third seat block 7 and the pressing block 12, and the end of the fourth positioning post 25 is inserted obliquely into the through hole located at the lower end of the support plate.

[0036] Then drive the telescopic end of the third positioning cylinder 6 in the clamping assembly to extend outwards to drive the third positioning post 8 to move obliquely forward and upwards until the front end of the third positioning post 8 is inserted into the hole located at the front end of the support plate. At the same time, drive the telescopic end of the clamping cylinder 10 to contract inwards to drive the pressing block 12 to move backward and downwards by means of the pressing strip 11 until both pressing teeth 121 are tightly pressed on the support plate to complete the fixation of the upper end of the support plate, and the front end of the third positioning post 8 is inserted between the two pressing teeth 121.

[0037] Then drive the telescopic end of the first positioning cylinder 26 in the first positioning assembly to extend outwards to drive the first positioning post 27 to move obliquely forward and upwards, so that the upper end of the first positioning post 27 is inserted into the reference hole located on the lower side of the upper part of the support plate.

[0038] At the same time, drive the telescopic end of the second positioning cylinder 15 in the third positioning assembly to extend outwards to drive the second positioning post 17 to move obliquely forward and upwards, so that the upper end of the second positioning post 17 is inserted into the reference hole located on the lower side of the middle part of the support plate.

[0039] Finally, drilling can be carried out on the bent part at the upper end of the support plate.

[0040] When the hole positions in the upper part of the support plate change, the first knob bolt 32 can be screwed to drive the first seat block 3 to move left or right according to the principle of screw connection, thereby driving the first positioning cylinder 26 and the first positioning column 27 to move synchronously for adaptation.

[0041] When the hole positions in the middle part of the support plate change, the second knob bolt 33 can be screwed to drive the second seat block 16 to move left or right according to the principle of screw connection, thereby driving the second positioning cylinder 15 and the second positioning column 17 to move synchronously for adaptation.

[0042] When the structural dimensions in the lower part of the support plate change, the telescopic end of the first adjustment cylinder 19 in the second positioning assembly can be driven to extend outwards or contract inwards to drive the support bar 18 to tilt and move forward and upwards or backward and downwards, thereby driving the first U-shaped support 23, the second U-shaped support 13 and the baffle 31 to move synchronously through the second adjustment cylinder 28 and the connecting bar 20 to adapt to the longitudinal bending angle of the lower part of the support plate.

[0043] Driving the telescopic end of the second adjustment cylinder 28 to extend outwards or contract inwards can also drive the first U-shaped support 23, the second U-shaped support 13 and the baffle 31 to move left or right through the connecting bar 20 to adapt to the transverse bending angle of the lower part of the support plate.

[0044] After processing is completed, the telescopic end of the clamping cylinder 10 is driven to extend outwards to drive the pressing block 12 to move forward and upwards through the pressing strip 11, thereby driving the two pressing teeth 121 away from the support plate. At the same time, the telescopic ends of the first positioning cylinder 26, the second positioning cylinder 15 and the third positioning cylinder 6 are driven to contract inwards to drive the front ends of the first positioning column 27, the second positioning column 17 and the third positioning column 8 away from the support plate respectively, and then the support plate can be taken away upwards.

[0045] The utility model greatly improves the degree of automation. In addition to automatically completing the positioning and fixing of the support plate, it can also automatically adjust the angle and position of the positioning points to adapt to the support plate without manual operation, thereby simplifying the operation and improving the work efficiency.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
