It is necessary to re-release the positioning and flip the guide rail, and then re-position it before the bottom of the guide rail can be welded, which makes the device inconvenient to use and poor in practicality.

[0023] See also Figure 1-Figure 5 A guide rail tooling for facilitating welding positioning includes a mounting shell 1, two positioning mechanisms 2 are provided above the mounting shell 1, and an adjustment mechanism 3 is provided inside the mounting shell 1;

[0024] The positioning mechanism 2 enables the guide rail to flip over without re-clamping, and the adjustment mechanism 3 is used to drive the guide rails on both sides to move closer to each other.

[0025] The positioning mechanism 2 includes two connecting seats 201, and a first support plate 202, a side plate 206 and a connecting plate 208 are fixed to the top of the connecting seat 201. A slide rail 203 is fixed to the surface of the first support plate 202, and a slider 204 is slidably connected to the surface of the slide rail 203. A positioning cylinder 205 is fixedly connected to the surface of the slider 204. Two positioning screw rods 221 are threaded through the surface of the positioning cylinder 205, and one end of the positioning screw rod 221 is rotatably connected to the first clamping plate 209. Two second support plates 210 are fixed to the inner wall of the positioning cylinder 205. A fastening screw rod 211 is threaded through the surface of the upper second support plate 210, and a second clamping plate 212 is fixed to the bottom end of the fastening screw rod 211. The surface of the side plate 206 is rotatably connected to the rotating shaft 207, and the rotating shaft 207 passes through the connecting plate 208. A driving motor 216 is fixed to the surface of one side plate 206. The output shaft of the driving motor 216 passes through the side plate 206 and is fixedly connected to the rotating shaft 207. A driving structure is installed on the surface of the connecting plate 208.

[0026] The guide rail can be placed on the surface of the second support plate 210 on the lower side. Rotating the positioning screw rods 221 on both sides can make the first clamping plates 209 on both sides move toward each other, so that the guide rail can be positioned in the middle position of the positioning cylinder 205. Rotating the fastening screw rod 211 again allows the second clamping plate 212 to position the top of the guide rail downward. Then, the adjusting mechanism 3 is used to make the connecting seats 201 on both sides drive the guide rails to approach each other. After the surfaces of the guide rails on both sides contact, the welding process of the guide rail surfaces can be started. When the bottom of the guide rail needs to be welded, the driving motors 216 on both sides are started at the same time, driving the rotating shaft 207 to rotate, so that the rotating shaft 207 can drive the positioning cylinder 205 to rotate by cooperating with the driving structure. At this time, the slider 204 will slide together on the surface of the slide rail 203, thereby supporting the positioning cylinder 205, so that the guide rails on both sides can be directly flipped over without repositioning, thereby improving the efficiency of the guide rail welding process.

[0027] Furthermore, the driving structure on the surface of the connecting plate 208 includes a driven shaft 213, one end of which is rotatably connected to the surface of the connecting plate 208. A transmission wheel 217 is fixed to the surface of the rotating shaft 207 and the driven shaft 213. There are two transmission wheels 217 on the surface of the rotating shaft 207, and the upper and lower transmission wheels 217 are connected by a belt drive. A gear 215 is fixed to the surface of the driven shaft 213, and a gear ring 214 is fixed to the surface of the positioning cylinder 205. The gear 215 meshes with the gear ring 214.

[0028] When the driving motor 216 drives the rotating shaft 207 to rotate, the rotating shaft 207 can drive the two transmission wheels 217 on its surface to rotate at the same time, so that the lower transmission wheel 217 can be driven by the belt and the upper transmission wheel 217 to drive the driven shafts 213 on the surfaces of the two connecting plates 208 to rotate at the same time, and then the gear 215 can drive the gear ring 214 to rotate, thereby achieving the effect of the positioning cylinder 205 driving the guide rail to rotate.

[0029] Furthermore, two third support plates 219 are fixed on the top of the connecting seat 201. The top of the third support plate 219 is rotatably connected to a support roller 220. The surface of the support roller 220 is slidably connected to the surface of the positioning cylinder 205.

[0030] The bottom of the positioning cylinder 205 can contact the surface of the supporting roller 220, so that the positioning cylinder 205 can obtain a supporting effect, making the positioning cylinder 205 more stable.

[0031] Furthermore, the adjustment mechanism 3 includes an adjustment motor 301, which is fixed to the surface of the mounting shell 1. The output shaft of the adjustment motor 301 extends into the interior of the mounting shell 1 and is fixed with a bidirectional screw rod 302. One end of the bidirectional screw rod 302 is rotatably connected to the inner wall of the mounting shell 1. Four first slides 303 are threadedly connected to the surface of the bidirectional screw rod 302. A plurality of slide grooves 304 are opened on the surface of the mounting shell 1. The first slides 303 are slidably connected to the surfaces of the slide grooves 304. The top of the first slide 303 is fixedly connected to the bottom of the connecting seat 201.

[0032] When the regulating motor 301 is started, it can drive the bidirectional screw rod 302 to rotate, so that the first slides 303 on both sides can be affected by the threads and start to move in opposite directions, so that the connecting seats 201 on both sides can approach each other.

[0033] Furthermore, two second guide rods 305 are fixed to the inner wall of the mounting shell 1, and four second slides 306 are slidably connected to the surface of the second guide rods 305, and the top of the second slide 306 is fixedly connected to the bottom of the connecting seat 201;

[0034] The connecting seat 201 can drive the second slide 306 to slide on the surface of the second guide rod 305, thereby improving the stability of the connecting seat 201 when moving.

[0035] Furthermore, a controller 4 is fixed on the surface of the mounting shell 1. The controller 4 is electrically connected to the drive motor 216 and the regulating motor 301. The drive motor 216 is a servo motor and a brake device is installed at its tail.

[0036] The controller 4 can operate multiple devices, and the use of a servo motor as the drive motor 216 can enable it to accurately control the number of rotations of the output shaft, and also enable the output shaft to achieve a self-locking effect when it stops running, so that the rotating shafts 207 on both sides can rotate synchronously.

[0037] Furthermore, a first guide rod 218 is passed through the surface of the positioning cylinder 205, and one end of the first guide rod 218 is fixedly connected to the surface of the first clamping plate 209;

[0038] When the first clamping plate 209 moves, the first guide rod 218 slides on the surface of the positioning tube 205, so that the first clamping plate 209 will not rotate when moving.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
