The support seat 101 is provided with a platform 103 on both sides, and the transverse plate 3011 is overlapped on the platform 103. The protective cover 3012 mainly protects the shift roller 306 as a whole, and the platform 103 plays a role in providing preliminary support for the transverse plate 3011.

[0049] Embodiment 2, based on the above embodiment and the difference between this embodiment and the present embodiment is: Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a clamping seat 2023 is installed on the slide 202, and the clamping seat 2023 is L-shaped. A transmission shaft 2021 is installed inside the clamping seat 2023. A torsion spring 2022 is installed on the transmission shaft 2021 between the clamping seat 2023 and the slide 202. One end of the torsion spring 2022 is clamped on the clamping seat 2023, and the other end of the torsion spring 2022 is clamped on the transmission shaft 2021. After the transmission shaft 2021 rotates, the torsion spring 2022 on the transmission shaft 2021 is twisted synchronously, and the torsion spring 2022 is used to facilitate the reset operation later.

[0050] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a specific embodiment, a limit plate 402 is installed on the support seat 101, and an inner cavity 4021 is opened at the bottom of the limit plate 402, the screw shaft 4011 is rotatably installed on the inner wall of the inner cavity 4021, and the drive motor 401 is installed on the outer side of the limit plate 402, and the sliding sleeve 4022 is slidably arranged in the inner cavity 4021. The operator starts the drive motor 401, and the drive motor 401 drives the screw shaft 4011 to rotate in the inner cavity 4021, and the screw shaft 4011 is meshed with the sliding sleeve 4022, and the sliding sleeve 4022 slides in the inner cavity 4021 at this time, and the sliding sleeve 4022 is in a limited state, and then the rotation of the screw shaft 4011 drives the sliding sleeve 4022 to slide horizontally.

[0051] like Figure 3 and Figure 7As shown, further, the support seat 101 is provided with friction stripes 3021, and the friction stripes 3021 are adapted to the friction wheel 302, the rotation center positions of the friction wheel 302 and the rotating disk 303 are on the same axis, and the protrusion 3031 is installed at the eccentric position of the rotating disk 303. During the process of the support arm 301 and the horizontal plate 3011 rotating in a vertical state, the friction wheel 302 on the support arm 301 rotates synchronously, and finally the friction wheel 302 of the support arm 301 can be meshed with the friction stripes 3021, and during the process of the support arm 301 and the horizontal plate 3011 moving horizontally, the friction wheel 302 on the support arm 301 can slide on the friction stripes 3021, thereby driving the entire friction wheel 302 to rotate, and after the friction wheel 302 rotates, the rotating disk 303 on the friction wheel 302 rotates synchronously, and the position of the protrusion 3031 on the rotating disk 303 changes synchronously.

[0052] Embodiment 3, based on the above embodiment and the difference between this embodiment and the present embodiment is: Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, a strip groove 3041 is provided on the rocking plate 304, and the strip groove 3041 is slidably connected with the protrusion 3031, and a positioning shaft 3042 is installed at the rotation center of the rocking plate 304, and the positioning shaft 3042 movably penetrates the support arm 301, and a fixing plate 3043 is installed on the positioning shaft 3042, and the fixing plate 3043 is installed in the interlayer opened inside the support arm 301. A guide shaft 3052 is installed at the rotation center of the driving gear 305, and the end of the guide shaft 3052 and the rotation center of the shift roller 306 are connected to each other, the outer edge of the driving gear 305 penetrates the horizontal plate 3011, and a positioning slide groove 3064 is installed on the side wall of the horizontal plate 3011, and the positioning slide groove 3064 is a through groove, and the positioning slider 3062 is slidably set on the positioning slide groove 3064. When the protrusion 3031 rotates, the protrusion 3031 can slide on the strip groove 3041 of the rocking plate 304, thereby driving the rocking plate 304 to drive the positioning shaft 3042 to swing back and forth. The positioning shaft 3042 is installed with a fixed plate 3043. At this time, the position of the teeth 3051 on the fixed plate 3043 changes, and the teeth 3051 mesh with the driving gear 305. Finally, the driving gear 305 starts to rotate, and the driving gear 305 drives the shift roller 306 to rotate through the guide shaft 3052. The position of the spiral groove 3061 on the shift roller 306 changes, thereby driving the positioning slide block 3062 limited by the positioning slide groove 3064 to slide back and forth, and finally driving the first scanner 3063 on the positioning slide block 3062 to move, so that different positions of the workpiece can be scanned to increase the scanning area.

[0053] like Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, further, a flat plate 307 is installed on the positioning shaft 3042, and a guide slider 3072 is installed on the outer shell of the second scanner 3073. The guide slider 3072 is slidably set on the inclined groove 3071. The guide slider 3072 is movably penetrated and installed with a limit rod 3074. One end of the limit rod 3074 is connected to the inner wall of the horizontal plate 3011, and the other end of the limit rod 3074 is installed with an anti-slip plate 3076. The diameter of the anti-slip plate 3076 is larger than the diameter of the limit rod 3074. An extrusion spring 3075 is sleeved on the limit rod 3074. One end of the extrusion spring 3075 is clamped on the inner wall of the horizontal plate 3011, and the other end of the extrusion spring 3075 is clamped on the guide slider 3072. During the rotation of the positioning shaft 3042, the position of the plate 307 on the positioning shaft 3042 changes synchronously, and the position of the inclined groove 3071 on the plate 307 changes. The inclined groove 3071 can make the limited guide slider 3072 slide, and the position of the second scanner 3073 on the guide slider 3072 changes synchronously, thereby increasing the scanning range. The guide slider 3072 as a whole slides along the limiting rod 3074, and the extrusion spring 3075 on the limiting rod 3074 is squeezed synchronously. The extrusion spring 3075 facilitates the subsequent resetting operation, wherein the anti-slip plate 3076 holds the guide slider 3072 and will not detach from the limiting rod 3074.

[0054] The implementation principle of the steel component virtual pre-assembly detection device based on 3D reverse forming in this embodiment is as follows:

[0055] When testing is required, the operator first needs to place the steel component on the testing table 102 .

[0056] Then the operator needs to perform a scan test.

[0057] The operator starts the driving motor 401, and the driving motor 401 drives the screw shaft 4011 to rotate in the inner cavity 4021. The screw shaft 4011 is meshed with a sleeve 4022, and the sleeve 4022 slides in the inner cavity 4021 at this time, and the sleeve 4022 is in a limited state, so that the rotation of the screw shaft 4011 drives the sleeve 4022 to slide horizontally.

[0058] At this time, the slide seat 202, the transmission shaft 2021, the rocker arm 203 and the rocker bar 2031 on the sleeve 4022 slide horizontally, and when the rocker arm 203 moves to the slope 2012, the rocker arm 203 as a whole rotates due to the action of the slope 2012, and finally the rocker arm 203 and the rocker bar 2031 are rotated to a horizontal state. At this time, the transmission shaft 2021 on the rocker arm 203 rotates, and the torsion spring 2022 on the transmission shaft 2021 is twisted synchronously, and the torsion spring 2022 is used to facilitate the subsequent resetting operation.

[0059] After the transmission shaft 2021 rotates, it can drive the support arm 301 and the cross plate 3011 to rotate, so that the support arm 301 and the cross plate 3011 rotate to a vertical state. During the rotation process, the first scanner 3063 and the second scanner 3073 rotate synchronously, thereby scanning one side end face of the workpiece.

[0060] Then, the screw shaft 4011 can continue to drive the rocker arm 203 to slide on the horizontal plane of the shift plate 2011. At this time, the first scanner 3063 and the second scanner 3073 will not be deflected. At this time, the first scanner 3063 and the second scanner 3073 slide horizontally, so that the first scanner 3063 and the second scanner 3073 can scan the front, back and top of the workpiece.

[0061] When the rocker arm 203 and the rocker bar 2031 move to the inclined surface 2014 of the guide block 2013, the roller 2032 on the rocker bar 2031 slides along the inclined surface 2014, thereby driving the rocker arm 203 and the rocker bar 2031 to continue to rotate at a certain angle, thereby driving the first scanner 3063 and the second scanner 3073 to start rotating as a whole. At this time, during the rotation of the first scanner 3063 and the second scanner 3073, the other side end face of the workpiece can be scanned, thereby completing the scanning operation of the workpiece.

[0062] When the support arm 301 and the cross plate 3011 rotate to a vertical state, the friction wheel 302 on the support arm 301 rotates synchronously, and finally the friction wheel 302 of the support arm 301 can mesh with the friction stripe 3021. As the support arm 301 and the cross plate 3011 move horizontally, the friction wheel 302 on the support arm 301 can slide on the friction stripe 3021, thereby driving the entire friction wheel 302 to rotate. After the friction wheel 302 rotates, the turntable 303 on the friction wheel 302 rotates synchronously, and the position of the protrusion 3031 on the turntable 303 changes synchronously. The protrusion 3031 can slide on the strip groove 3041 of the rocking plate 304, thereby driving the rocking plate 304 to drive the positioning shaft 3042 to swing back and forth.

[0063] A fixed plate 3043 is installed on the positioning shaft 3042. At this time, the position of the teeth 3051 on the fixed plate 3043 changes, and the teeth 3051 are meshed with the driving gear 305. Finally, the driving gear 305 starts to rotate, and the driving gear 305 drives the shift roller 306 to rotate through the guide shaft 3052. The position of the spiral groove 3061 on the shift roller 306 changes, and then the positioning slider 3062 limited by the positioning slide groove 3064 is driven to slide back and forth, and finally the first scanner 3063 on the positioning slider 3062 can be driven to move, so that different positions of the workpiece can be scanned and the scanning area can be increased.

[0064] During the rotation of the positioning shaft 3042, the position of the plate 307 on the positioning shaft 3042 changes synchronously, and the position of the inclined groove 3071 on the plate 307 changes. The inclined groove 3071 can make the limited guide slider 3072 slide, and the position of the second scanner 3073 on the guide slider 3072 changes synchronously, thereby increasing the scanning range. The guide slider 3072 as a whole slides along the limiting rod 3074, and the extrusion spring 3075 on the limiting rod 3074 is squeezed synchronously. The extrusion spring 3075 facilitates the subsequent resetting operation, wherein the anti-slip plate 3076 holds the guide slider 3072 and will not detach from the limiting rod 3074.

[0065] Through the above operations, the scanning of the workpiece can be fully completed, and in conjunction with the reverse forming technology, the scanned and formed components can be virtually assembled in professional software, ultimately resulting in possible pre-assembly problems and minimal modification plans, thus guiding factory processing and production.
