[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 2 As shown, the present invention provides a fixing device for processing the shell sheet of an electric tricycle, comprising a bracket 1, a rotating support mechanism, and a fixing mechanism.

[0034] In this embodiment, a counterweight 2 is provided on the bottom crossbeam of the support 1 to stabilize the support 1.

[0035] The rotating support mechanism includes a support frame 3, a turntable 4, and a limiting mechanism 5; the support frame 3 has a square structure; the two ends of the support frame 3 are fixed with support shafts 6, and the support frame 3 can rotate horizontally and vertically on the bracket 1 through the support shafts 6 at both ends.

[0036] The support frame 3 has a contour area 7, which facilitates the accurate placement of the electric tricycle shell sheet and subsequent processing.

[0037] The turntable 4 is sleeved and fixed to the outer end of any support shaft 6. A disc 8 is fixed to the inner side of the turntable 4. The disc 8 and the turntable 4 share the same axis. The disc 8 is sleeved on the support shaft 6.

[0038] like Figure 4 As shown, the side surface of the disk 8 is provided with a plurality of slots 9 at equal intervals; as Figure 3As shown, the limiting mechanism includes a vertical rod 10, a connecting rod 11, and a spring 12. The vertical rod 10 is vertically slidably mounted on the support 1 on the side near the turntable 4, and the top of the vertical rod 10 is located directly below the disc 8. The lower part of the vertical rod 10 has a first long through hole 13 along its length direction, and the lower part of the support 1 has a second long through hole 14. One end of the connecting rod 11 is hinged to the bottom of the support 1, and the connecting rod 11 passes through the first long through hole 13 and the second long through hole 14 in sequence. One end of the spring 12 is connected to the connecting rod 11, and the other end is connected to the support 1. The spring 12 is located between the first long through hole 13 and the second long through hole 14.

[0039] The fixing mechanism includes several fixing clamps 15, which are distributed on the support frame 3 and located around the contour area 7, for fixing the electric tricycle shell plate to be processed.

[0040] In this embodiment, an elastic rubber layer (not shown in the figure) is provided on the working surface of the pressure plate on the fixing clamp 15 to serve as a buffer and prevent the electric tricycle shell sheet from being crushed.

[0041] In this embodiment, a foot pedal 16 is fixed to the end of the connecting rod 11, which is convenient for the operator to step on the foot pedal 16 to drive the vertical rod 10 to move downward and disengage from the slot 9 on the disc 8, so that the operator can rotate the support frame 3.

[0042] In this embodiment, as Figure 2 As shown, adjustment modules are provided at the bottom corners of the bracket 1. Each adjustment module includes a bolt 17, a nut 18, and a washer 19. The bolt 17 is vertical and its thread passes through the bottom of the bracket 1. The washer 19 is fixed to the bottom of the bolt 19. The nut 18 is sleeved on the bolt. With this configuration, by rotating the bolt 17 on the adjustment module, the bracket 1 is brought to a horizontal position, and then the nut 18 is tightened to ensure the accuracy of subsequent processing of the electric tricycle shell sheet.

[0043] like Figure 5 As shown, when fixing the electric tricycle shell plate 20, it is first placed in the contour area 7 on the support frame 3 and fixed by the fixing clamp 15; then the turntable 4 is rotated to a suitable angle, the worker releases the foot pedal 16, and the connecting rod 11 rotates upward around the hinge point with the bracket 1 under the elastic force of the spring 12, driving the vertical rod 10 to slide upward and insert into the corresponding slot 9 of the disc 8, thereby locking the disc 9 and fixing the support frame 3, which facilitates the processing of the electric tricycle shell plate by external equipment.

[0044] The inventors need to explain that the support frame cannot be fixed after rotating at any angle. The number of slots on the disc can be increased to allow the support frame to be fixed after rotating to a suitable angle. In addition, since the shape of the electric tricycle shell is fixed, it only needs to be rotated to a few fixed angles.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
