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] A clamping and transposing device for a four-door assembly line provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] Combination Figure 1-Figure 3 As shown, the utility model provides a clamping and shifting device for a four-door assembly line, including a hanging rail 100 for lifting vehicle doors, a load block 101 being slidably connected to the hanging rail 100, an electric telescopic rod 102 being fixedly installed at the bottom of the load block 101, a free end of the electric telescopic rod 102 being fixedly connected to a support platform 103 for carrying the vehicle door, a clamping mechanism 200 and a positioning mechanism 300 for fixing the vehicle door are provided on the hanging rail 100, and the vehicle door is fixed in multiple directions to ensure that the vehicle door remains stable during the shifting process, avoid shaking or tilting, and improve the safety and stability of the operation.

[0026] The clamping mechanism 200 includes a connecting frame 201 fixed on the support platform 103, and an arc-shaped plate 205 slidably connected to both sides of the connecting frame 201. The upper and lower ends of the arc-shaped plate 205 are hinged with a clamping block 206. Two support bars 207 are fixedly connected to the arc-shaped plate 205. A spring 208 is fixedly connected between the support bar 207 and the clamping block 206. The car door is placed on the support platform 103, and then the arc-shaped plates 205 on both sides are moved toward the middle to fix the car door from both sides. The car door is not a regular shape, and the clamping blocks 206 on both sides can assist in positioning the car door to adapt to different shapes of parts on the car door, thereby further improving the firmness of the fixation.

[0032] Specifically, the support platform 103 is L-shaped, and the vehicle door is placed on the support platform 103, which can support the vehicle door from the bottom, avoiding moving the vehicle door to other positions for replacement, and facilitating other processing of the vehicle door.
