[0002] Clay model is an important process to display the designer's design works in three dimensions. Clay model is also the final physical model that is closest to the mass-produced car shape. Automobile clay model usually places the initial support structure made of foam plastic and steel plate on the bench, and then applies clay on the surface of the support structure to form the final clay model. After the clay model is made, it needs to be finely cut and 3D scanned on the bench. The existing bench, cutting mechanism and scanning mechanism are separated, which is inconvenient to use.

[0003] A Chinese patent with authorization announcement number CN219757252U discloses a car clay model positioning stand. The device uses a first motor to drive a first screw rod to rotate, so that the slide position moves and the distance between the clay model and the laser emitter is adjusted, which can reduce detection errors and improve reliability. A second motor is used to rotate a second screw rod to increase the distance between the first laser emitter and the second laser emitter. At the same time, the angle of the second laser emitter changes, and the position of the laser emitter can be adjusted according to the size of the model. It has a wide range of applications.

[0004] However, the device still has some shortcomings: the device receives laser through a laser receiving plate, but the surface structure of the car model is complex, the laser cannot be reflected to the laser receiving plate in the recessed parts of the car body, and it is difficult for the device to scan the bottom of the clay model.

The limit assembly includes a movable plate 43, a latch 44 and a hydraulic cylinder B45. A plurality of limit grooves 102 are arranged on the bottom plate 1 along the sliding track of the slider 42. The movable plate 43 is slidably connected to the slider 42, and the movable plate 43 is connected to the latch 44. The hydraulic cylinder B45 is connected to the slider 42 and drives the movable plate 43 to rise and fall, so as to drive the latch 44 to be inserted into or pulled out of the corresponding side limit groove 102. The slide seats 9 on both sides are symmetrical with respect to the support platform 2. A telescopic rod 10 is arranged on the slide seat 9. The telescopic rod 10 includes an outer tube and an inner rod. The inner rod is connected to the mounting seat 12. The inner rod is slidably connected to the outer tube. A driving assembly B11 for driving the inner rod to rise and fall is arranged in the outer tube. The mounting seat 12 is connected to the mechanical arm 13, and the mechanical arm 13 is connected to the quick-change tool connector 14. A telescopic rod 10 is arranged on the slide 9, and the telescopic rod 10 includes an outer tube and an inner rod.

[0025] In this embodiment, before making the clay model, components made of foamed plastic and steel plate are first placed on the support platform 2, and the components are adjusted to be in a central position on the support platform 2, and then the clay model is applied. After the clay model is applied, the laser scanner is connected to the quick-change tool joint 14, and the laser scanner scans and moves under the drive of the linear module 8 and the mechanical arm 13, and the model is scanned as a whole. Since the bottom of the model and the entire wheel need to be scanned, the hydraulic cylinder A4 is started at this time, and the hydraulic cylinder A4 drives the scissor-type bracket 3 to move, and the height of the support platform 2 is adjusted by changing the connecting rod angle of the scissor-type bracket 3, so that the clay model is lifted to a certain height from the ground.

The laser scanner scans the appearance of the model and transmits the three-dimensional information of the entire model back to the controller. After data conversion, the controller compares the scanned model with the original design model to determine the parts of the model that need to be improved, and plugs the cutting head into the quick-change tool connector 14. The engineer starts the linear module 8 and the robot arm 13 according to the set model to adjust the cutting position and angle of the cutting head. The two sets of cutting heads work synchronously to ensure the symmetry of the construction process.

At this time, the hydraulic cylinder C7 can be started, and the hydraulic cylinder C7 pulls down the support plate 6.

At this time, the staff can easily push the clay model, and after adjusting the clay model to the center, the support plate 6 is pushed up to support and limit the chassis of the clay model. This structure facilitates improving the accuracy and symmetry of tool processing.
