[0037] Embodiment

[0038] As Figure 1 and Figure 2 shown, a clamping device for an automotive sunroof guide rail includes a support component 10 and a fixing component 20. The support component 10 includes an installation part 11, a flipping part 12 and a limiting part 13. The flipping part 12 and the limiting part 13 are both installed on the installation part 11. The installation part 11 is used to drive the flipping part 12 to flip, and the limiting part 13 is used to limit the flipping of the flipping part 12; the fixing component 20 includes a driving part 21 and a clamping part 22. The driving part 21 is installed on the flipping part 12 and is used to drive the clamping part 22 to rotate around the center of the flipping part 12. The clamping part 22 is installed on the driving part 21 and is used to fix the automotive sunroof guide rail.

[0039] Specifically, the flipping part 12 is used to install the driving part 21 and the clamping part 22, and can drive the driving part 21 and the clamping part 22 to flip on the installation part 11. The limiting part 13 is used to limit the rotation of the flipping part 12. The driving part 21 can adjust the distance between the two clamping parts 22, so as to be able to fix and move the two automotive sunroof guide rails in the direction of moving away from or approaching each other, which is convenient for processing them.

[0040] As Figure 2 and Figure 3 shown, the installation part 11 includes a support frame 111. Four guide grooves 112 are opened on one side of the support frame 111, and a motor base 1 113 is connected to the other side by bolts. A motor 1 114 is fixedly connected to the top of the motor base 1 113.

[0041] Specifically, the support frame 111 is in a "U" shape.

[0042] As Figure 2 , Figure 3 and Figure 4 shown, the flipping part 12 includes a fixing plate 121. On one side of the fixing plate 121, two annular sliding rails 122 are welded. On the other side, a rotating shaft is fixedly connected. The two rotating shafts are respectively rotatably sleeved in the inner circles on both sides of the support frame 111. One of the rotating shafts is fixedly connected to the output end of the first motor 114, and the other rotating shaft is fixedly connected to a circular positioning plate 123. A plurality of positioning holes are formed in the outer circle of the circular positioning plate 123. On one side of an annular sliding rail 122, a first spur gear 125 is fixedly connected through a connecting plate 124.

[0043] Specifically, the fixing plate 121 and the annular sliding rail 122 rotate around the rotating shaft as the axis. The centers of the annular sliding rail 122 and the first spur gear 125 coincide. At the same time, the four guiding grooves 112 are arranged in an annular array with the centers of the rotating shaft and the circular positioning plate 123 as the origin.

[0044] As Figure 2 , Figure 3 and Figure 5 shown, the limiting part 13 includes a second spur gear 131 and a first hydraulic cylinder 134. The second spur gear 131 is movably sleeved on the outer circle of the rotating shaft connected to the circular positioning plate 123. Four positioning members 132 are installed on the second spur gear 131. The positioning members 132 are adapted to the circular positioning plate 123. The first hydraulic cylinder 134 is fixed on the outside of the support frame 111, and the output end of the first hydraulic cylinder 134 is fixedly connected to a rack 135. The rack 135 meshes with the second spur gear 131.

[0045] Specifically, the four sliding openings formed in the second spur gear 131 are arranged in an annular array with the center of the circular positioning plate 123 as the origin. At the same time, the radius of the second spur gear 131 is larger than the diameter of the guiding groove 112. When the first hydraulic cylinder 134 drives the rack 135 to move, the rack 135 will drive the second spur gear 131 to rotate on the support frame 111.

[0046] As Figure 6 shown, the positioning member 132 includes a guiding sliding sleeve 1321. A guiding sliding rod 1322 is fixedly sleeved in the inner circle of the guiding sliding sleeve 1321. A positioning insertion rod 1323 is fixedly sleeved on the outer circle of the guiding sliding rod 1322. One end of the positioning insertion rod 1323 is adapted to the positioning hole. Four sliding openings are formed in the second spur gear 131, and the guiding sliding sleeve 1321 is slidably sleeved in the sliding openings.

[0047] Specifically, since the sliding opening is inclined and the guiding groove 112 is horizontally and vertically arranged, the rotation of the second spur gear 131 will drive the guiding slide bar 1322 to slide in the guiding groove 112 through the guiding sliding sleeve 1321, causing the positioning insertion rod 1323 to move away from or insert into the positioning hole of the circular positioning plate 123.

[0048] As Figure 2 and Figure 7 shown, the driving part 21 includes a placement rack 211. A slider 212 is welded to the outer wall of the placement rack 211. The slider 212 is slidably connected to the inner wall of the annular slide rail 122. A second motor 213 is fixedly connected to one side of the placement rack 211. The output end of the second motor 213 is fixedly connected to a third spur gear 214. The third spur gear 214 meshes with the first spur gear 125. A second motor base 215 is installed on one side of the placement rack 211 by bolts. The second motor base 215 is fixedly connected to a third motor 216. The output end of the third motor 216 is fixedly connected to a bidirectional threaded rod 217. One end of the bidirectional threaded rod 217 penetrates through one side of the placement rack 211 and is rotatably connected to the other side of the placement rack 211; the clamping part 22 includes L-shaped plates 221. Both L-shaped plates 221 are rotatably sleeved on the outer circle of the bidirectional threaded rod 217 through thread sleeves. One side of the L-shaped plate 221 is slidably connected to the placement rack 211. Hydraulic cylinder seats 223 are welded to the sides of the two L-shaped plates 221 close to each other. A second hydraulic cylinder 224 is installed on one side of the hydraulic cylinder seat 223 by bolts. The output end of the second hydraulic cylinder 224 is fixedly connected to a push plate 225. The L-shaped plate 221 is provided with a through opening 222. The push plate 225 penetrates through the through opening 222 and is fixedly connected to a clamping plate 226.

[0049] Specifically, through the sliding fit between the slider 212 and the annular slide rail 122, and the meshing between the third spur gear 214 and the first spur gear 125, when the second motor 213 drives the third spur gear 214 to rotate, the placement rack 211 will rotate within the inner circle of the annular slide rail 122. When the third motor 216 drives the bidirectional threaded rod 217 to rotate, through the sliding fit between the L-shaped plate 221 and the placement rack 211, the two L-shaped plates 221 will move towards or away from each other.

[0050] Working principle: First, start the second hydraulic cylinder 224 to push the push plate 225 and the clamping plate 226 to move. The automotive sunroof guide rail can be clamped between the L-shaped plate 221 and the clamping plate 226. Then start the third motor 216 to drive the bidirectional threaded rod 217 to rotate. When the bidirectional threaded rod 217 rotates, through the sliding fit between the L-shaped plate 221 and the placement rack 211, the two L-shaped plates 221 will move towards or away from each other, so as to combine or separate the two automotive sunroof guide rails, facilitating their processing;

[0051] When the direction needs to be adjusted, start the second motor 213 to drive the third spur gear 214 to rotate. Through the sliding fit between the slider 212 and the annular slide rail 122, when the third spur gear 214 rotates, the placement rack 211 will rotate within the inner ring of the annular slide rail 122, enabling the automobile sunroof guide rail to flip with the X-axis as the axis. When the automobile sunroof guide rail needs to flip with the Y-axis as the axis, start the first hydraulic cylinder 134 to drive the rack 135 to move. Since the rack 135 meshes with the second spur gear 131, the movement of the rack 135 will drive the second spur gear 131 to rotate. Because the sliding port is inclined and the guide groove 112 is horizontally and vertically arranged, the rotation of the second spur gear 131 will drive the guide slide rod 1322 to slide within the guide groove 112 through the guide sleeve 1321, causing the positioning plug 1323 to move away from or insert into the positioning hole of the circular positioning plate 123. After the positioning plug 1323 is disengaged from the positioning hole, the first motor 114 can be started to drive the fixed plate 121 and the annular slide rail 122 to flip through the rotating shaft. After flipping, start the first hydraulic cylinder 134 again to drive the positioning plug 1323 to re-insert into the positioning hole through the second spur gear 131 to restrict the circular positioning plate 123.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
