[0050] like Figure 1 , Fig. 9 As shown, the measuring module A8 includes a ruler, the upper surface and side surfaces of which are marked with specific dimensions. When the slide slides with the vehicle body, the ruler can read the movement of the slide and the vehicle body and measure the length of the vehicle body after movement.
[0051] like Fig.10 As shown, the design of the positioning pin seat A9 corresponds to the positioning hole of the vehicle body. The positioning pin seat A9 is distributed according to the positions of the positioning holes of the vehicle body, so that the vehicle body can be accurately inserted on the positioning pin seat A9.
[0052] The height control unit A10 controls the up and down sliding direction and sliding amount of the top of the positioning pin seat A9 relative to the plane of the base A2. The height control unit A10 is used to adjust the height of the vehicle body relative to the base A2. Fig.11 As shown, it can be designed as a column, the length of which is adjustable, and a column with a suitable height can be selected according to the height of vehicle components. The column is fixed to the slide through a threaded hole of the slide.
[0053] Before using the measurement module A8, Figure 1 As shown, first lock the slide at the position where the scale shows 0, and then place the vehicle body to be cut or processed on the positioning pin seat A9 on the slide, as shown in FIG. Figure 2 As shown, ensure that the front and rear body locating pin seats A9 are accurately and correctly inserted into the body locating holes and clamped, then adjust the height of the vehicle body relative to the slide by adjusting the height control unit A10, and then cut the body. During the modification process, move the slide as needed to increase the spacing between the body parts.
[0054] After cutting is completed, the slide table is moved by rotating the slide control unit, such as Figure 3 As shown, the front and rear of the vehicle body are separated to a designed distance according to the scale of the measuring module 8 .
[0055] Subsequently, the remaining vehicle lengthening and splicing were completed according to the prototype vehicle lengthening plan.
[0056] In one embodiment, the multiple slide units include a first slide A3 and a second slide A4, and the first slide A3 and the second slide A4 are independently distributed on both sides of the base A2. The first slide A3 supports the front part of the vehicle and slides with the front part, and the second slide A4 supports the rear part of the vehicle and slides with the rear part.
[0057] Specifically, when the length needs to be cut and spliced, two slides can be set as an example, with the front half of the vehicle placed on the first slide A3 and the back half of the vehicle placed on the second slide A4. The cut parts can also be placed on different slides according to the parts that need to be cut, so as to achieve multi-angle cutting and splicing of the vehicle.
[0058] In one embodiment, the sliding control unit includes a turntable and a ball screw feeding mechanism;
[0059] The turntable and ball screw feeding mechanism includes a first turntable A12, a first ball screw feeding unit, a second turntable A7 and a second ball screw feeding unit.
[0060] Specifically, the turntable is used to realize the rotational motion of the object, and the ball screw feed mechanism is a high-precision transmission component used to convert the rotational motion into linear motion, or convert the linear motion into rotational motion, thereby realizing the multi-angle motion of the slide.
[0061] In one embodiment, the first turntable A12 and the first ball screw feeding unit are disposed between the base A2 and the first slide A3 to control the movement of the first slide A3 on the base A2;
[0062] The second turntable A7 and the second ball screw feeding unit are arranged between the base A2 and the second slide A4 to control the movement of the second slide A4 on the base A2.
[0063] In one embodiment, the first slide platform A3 and the second slide platform A4 are provided with an adjustment unit, and the adjustment unit includes a plurality of threaded holes to adjust and fix various parts of the vehicle.
[0064] Specifically, Figure 1 , Figure 5 , Figure 6 As shown, the slide and the base A2 are both provided with evenly distributed threaded holes, and the positioning pin seat A9 can be installed on the threaded holes as required. When facing different models, only the layout of the positioning pin seat A9 needs to be changed, and there is no need to change the clamp device. The positioning pin seat A9 and the column are fixed to the slide by screws, bolts, etc.
[0065] In one embodiment, the vehicle body clamp device is further provided with a limit block, and the limit block limits the movement of the slide.
[0066] Specifically, when the slide moves to the desired position, Figure 7 As shown, the slide table is restricted by a limit block to prevent the slide table from moving during the cutting or splicing of the car body.
[0067] In one embodiment, the limit block includes a first limit block A11 and a second limit block A6;
[0068] The first limit block A11 is connected to the first slider and the base A2 to limit the movement of the first slide A3 on the base A2;
[0069] The second limit block A6 is connected to the second sliding block and the base A2 to limit the movement of the second slide table A4 on the base A2.
[0070] Specifically, when two slides are provided, two groups of limit blocks may be provided, and the two groups of limit blocks respectively limit the two slides so that the slides can move within a required range.
[0071] In one embodiment, the base A2 is provided with movable casters A5, and the movable casters A5 are placed under the base A2 and are used to move the vehicle body clamp device.
[0072] Specifically, the base A2 is provided with movable casters A5, which can move independently without occupying additional standard space.
[0073] In one embodiment, the vehicle body clamp device further comprises an adjustable foot A1 , which is disposed at the bottom of the base A2 and connected to a ground fixing point to adjustably raise the vehicle body clamp device.
[0074] Specifically, in order to further facilitate the construction workers to cut, assemble or perform other operations on the car body, such as Figure 1 , Figure 2 , Figure 3 As shown, an adjustable foot is provided at the bottom of the base A2 to raise or lower the entire device according to specific construction requirements. The structural diagram of the foot is shown in Figure 4 shown.
[0075] When the adjustable foot A1 is not in contact with the ground, the movable caster A5 can slide on the ground, which is convenient for moving the body clamp device. When the adjustable foot A1 is in contact with the ground, the movable caster A5 is away from the ground, which can prevent the body clamp device from moving, making it convenient for technicians to operate the body.
[0076] In one embodiment, the positioning pin seat A9 further includes a quick lock module, which fixes and locks the body parts.
[0077] Specifically, when the vehicle body is fixed to the positioning pin seat A9, the vehicle body can be further fixed by the quick lock module.
