A motor 102 is provided on the support plate 101 on the left side, and cantilever arms 2 are provided on both support plates 101. The cantilever arm 2 on the left side is connected to the motor 102 through a grooved wheel mechanism. Driven by the motor 102, it can rotate 90 degrees each time. After rotation, the positioning of the fender is completed by the limiting of the grooved wheel mechanism itself. A bottom support arm 3 is provided on the cantilever arm 2. Two contact parts 4 are symmetrically provided at the end of the bottom support arm 3 for contact support of the bottom surface of the fender. A clamping member 5 is provided above the bottom support arm 3, which works with the contact parts 4 to complete the clamping operation of the fender.

[0028] Preferred embodiments, in combination Figure 4 As shown, the cantilever 2 has a sliding groove 201, and multiple positioning holes 202 are evenly provided along the length of the sliding groove 201; the bottom support arm 3 is slidably connected to the sliding groove 201, and the left end of the bottom support arm 3 has a fixing hole 301 that mates with the positioning hole 202. By aligning the fixing hole 301 with the positioning holes 202 at different positions, the support position can be adjusted to meet the fixing requirements of different specifications of fenders; internal threads can be machined in the positioning hole 202 and the fixing hole 301, and the adjusted positioning can be achieved by screws, or a pin can be used for fixing.

[0029] Preferred embodiments, in combination Figure 1-4As shown, a rotating disk 203 is provided on the left side of the cantilever 2, and a bracket 103 connected to the rotating disk 203 is provided on the support plate 101. A circular channel is provided above the bracket 103, which cooperates with the rotating disk 203 to form a secondary support for the cantilever 2, thereby improving the stability and strength of the cantilever 2. In order to reduce friction, a bearing can be installed in the circular channel, and the bearing contacts the rotating disk 203.

[0030] Preferred embodiments, in combination Figure 2 and Figure 3 As shown, the contact part 4 includes a fixing rod 401 and a support head 402; the fixing rod 401 is inserted into the hole at the end of the bottom support arm 3 and connected to the bottom end of the fixing rod 401 with a nut to achieve the overall connection; the top of the fixing rod is fixedly connected to the support head 402, such as by welding or integral processing.

[0031] Preferred embodiments, in combination Figure 5 As shown, in order to achieve fine adjustment of the height of the support head 402, a threaded hole 403 can be machined in the center of the fixed rod 401. A threaded rod 404 connected to the threaded hole 403 is provided below the support head 402. The height can be adjusted by rotating the threaded rod 404. The top of the support head 402 is spherical, which facilitates the support of the fender.

[0032] In a preferred embodiment, the support head 402 is made of rubber to prevent damage to the fender during the support process.

[0033] Preferred embodiments, in combination Figure 1-3 As shown, the clamping component 5 includes an electric push rod 501, a connecting rod 502, and a swing arm 503.

A support spring 506 is sleeved on the slide rod 505. During the clamping process, when the preset force is reached, the pressing head 504 is slidably displaced by overcoming the elastic force of the support spring 506, thus avoiding excessive clamping force and reducing the requirements for the displacement accuracy of the electric push rod 501.

[0035] Preferred embodiments, in combination Figure 1As shown, a notch 104 is provided in front of the platform frame 1 to increase the operator's activity space and facilitate operation.

[0036] Working principle: Place both sides of the fender on the support heads 402 on the bottom support arms 3 on both sides. Then, start the electric push rod 501 to drive the pressing head 504 to contact the upper surface of the fender and complete the clamping and fixing. Then, the fender can be drilled. After drilling, the hole positions on the current surface are deburred. Then, start the motor 102 to drive the groove wheel mechanism to rotate twice continuously, which can complete the 180-degree flip of the fender. There is no need to disassemble and re-fix it, saving processing steps and greatly improving work efficiency. The reset of the cantilever 2 is achieved by the reverse rotation of the motor 102 to avoid affecting the wiring on the electric push rod 501.
