[0024] The utility model will be further described below in conjunction with the accompanying drawings.

[0025] like Figure 1 As shown, the bolster side frame disassembly and assembly device of one embodiment of the utility model comprises a support mechanism 1 and a clamping mechanism 2 arranged on both sides of the support mechanism 1, wherein the support mechanism 1 is used to support the bolster 100, and the clamping mechanism 2 is used to clamp the side frame 200. Figures 2 to 4As shown, the support mechanism 1 includes a first base 11, a first slide rail 12, a first slider 13, a second slider 14, a support seat 15, a first clamping plate 16, a first screw rod 17 and a first motor 18. The first slide rail 12 is horizontally arranged on the top surface of the first base 11, the first slider 13 and the second slider 14 are both slidably arranged on the first slide rail 12, the second slider 14 is arranged on both sides of the first slider 13, the support seat 15 is arranged on the first slider 13, the first clamping plate 16 is arranged on the second slider 14, the second slider 14 is connected to the first screw rod 17 and the threads at both ends of the first screw rod 17 have opposite rotation directions, and the first motor 18 is connected to the first screw rod 17.

[0026] The support seat 15 arranged on the first slider 13 can move freely along the first slide rail 12. Since the threads at both ends of the first screw rod 17 have opposite rotation directions, when the first motor 18 drives the first screw rod 17 to rotate, the first clamping plate 16 arranged on the second slider 14 can realize relative and opposite movements by relying on the first screw rod 17. When the bolster 100 is placed on the support seat 15 by a robot or other equipment, the first clamping plates 16 arranged on the second slider 14 on both sides of the support seat 15 move toward each other, and the bolster 100 is automatically centered while being clamped, thereby facilitating the disassembly or installation operation of the side frame 200 by the clamping mechanism 2. The disassembly and installation of the side frame 200 are both performed by the clamping mechanism 2, without the need for manual operation, thereby improving the safety and efficiency of the operation.

[0027] like Figure 2 As shown, the support base 15 includes a base 151, a turntable 152 and a bearing 153, the base 151 is fixed on the first slider 13, the bearing 153 is arranged between the base 151 and the turntable 152, and the turntable 152 is used to carry the bolster 100. The turntable 152 can rotate freely. When the bolster 100 is placed on the turntable 152, even if the bolster 100 is not completely straightened, the bolster 100 will be straightened under the clamping action of the first clamping plate 16, so that the clamping mechanism 2 can accurately clamp the side frame 200 on the bolster 100.

[0028] like Figure 1 As shown, the clamping mechanism 2 includes a translation assembly 21, a lifting assembly 22 and a clamping assembly 23. The clamping assembly 23 is arranged on the lifting assembly 22. The clamping assembly 23 includes two second clamping plates 231 arranged opposite to each other. The lifting assembly 22 is arranged on the translation assembly 21. By arranging the translation assembly 21 and the lifting assembly 22, the clamping assembly 23 can be flexibly moved in the horizontal and vertical directions to accurately complete the disassembly and installation operations of the side frame 200.

[0029] Specifically, Figure 5 and Figure 6As shown, the clamping assembly 23 also includes a mounting frame 232 and a second screw rod 233, a second motor 234, a second slide rail 235 and a third slider 236 arranged on the mounting frame 232. The third slider 236 is arranged on the second slide rail 235. The second clamping plate 231 is arranged on the third slider 236. The third slider 236 is connected to the second screw rod 233. The threads at both ends of the second screw rod 233 have opposite rotation directions. The second motor 234 is connected to the second screw rod 233. The second motor 234 is used to drive the second screw rod 233 to rotate. Since the threads at both ends of the second screw rod 233 have opposite rotation directions, the two second clamping plates 231 can move toward or away from each other, thereby clamping the side frame 200.

[0030] Two first clamping plates 16 are disposed on each second sliding block 14 , so that each side of the bolster 100 is clamped by two first clamping plates 16 , thereby ensuring stable clamping of the bolster 100 .

[0031] The lifting assembly 22 includes a third screw rod 221, a third motor 222, a fourth slider 223 and a third slide rail 224. The third motor 222 is connected to the third screw rod 221. The fourth slider 223 is arranged on the third slide rail 224. The fourth slider 223 and the third screw rod 221 are both connected to the mounting bracket 232. When the third motor 222 drives the third screw rod 221 to rotate, the mounting bracket 232 arranged on the third screw rod 221 moves up and down along the third screw rod 221, thereby realizing the lifting and lowering of the clamping assembly 23. Since the mounting bracket 232 is arranged on the fourth slider 223, the stability of the mounting bracket 232 when moving can be improved.

[0032] Furthermore, the fourth sliding block 223 is disposed on both sides of the mounting frame 232 , and the third screw rod 221 is connected to the middle of the mounting frame 232 , so that the movement of the mounting frame 232 is more stable.

[0033] like Figure 1 As shown, the translation assembly 21 includes a second base 211, a fourth slide rail 212, a fifth slider 213, a rack 214, a gear 215 and a fourth motor 216. The fourth slide rail 212 and the rack 214 are both horizontally arranged on the second base 211. The fifth slider 213 is arranged on the fourth slide rail 212 and connected to the lifting assembly 22. The gear 215 is arranged on the fourth motor 216 and meshes with the rack 214. The fourth motor 216 is arranged on the lifting assembly 22. When the fourth motor 216 drives the gear 215 to rotate, the gear 215 will move along the rack 214, so that the lifting assembly 22 as a whole also moves along the rack 214. The fifth slider 213 and the fourth slide rail 212 ensure the stability of the lifting assembly 22 when it moves.

[0034] like Figure 1 , Figure 5 and Figure 6As shown, the clamping mechanism 2 further includes two support columns 24 disposed oppositely on the second base 211, and the support columns 24 are used to place the side frame 200. The support columns 24 serve as a temporary placement position for the side frame 200, and the clamping assembly 23 clamps the side frame 200 from the support columns 24 and installs it on the bolster 100, or removes the side frame 200 on the bolster 100 and places it on the support columns 24 for a manipulator or other equipment to take away, so as to avoid the clamping assembly 23 directly receiving the side frame 200, thereby having higher safety and better operability.

[0035] Furthermore, the support column 24 is disposed on the outer side of the second base 211 , so that the support column 24 will not affect the operation of other components on the clamping mechanism 2 .

[0036] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
