[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. Figure 1-10 As shown, a fastening tool for a laser cutting machine used in the construction of a steel structure valve hall includes a bracket 1 for installing the laser cutting machine. There are two types of laser cutting machines: one is capable of moving relative to the bracket 1, and the position of the workpiece remains unchanged, thereby adjusting the cutting position; the other is when the laser cutting machine is fixed to the bracket 1, and the cutting position is adjusted by moving the workpiece.

[0032] The middle part of the bracket 1 is provided with a plurality of equidistant and parallel fixing mechanisms 2, the fixing mechanism 2 includes a base 201, and a sliding seat 202 is symmetrically slidably connected above the base 201. The two fixing mechanisms 2 can be moved closer to or away from each other through the sliding seat 202. A vertical telescopic member 203 is fixedly installed above the sliding seat 202. The vertical telescopic member 203 can adjust the height of the workpiece by vertical movement so that the workpiece can be located within the cutting range of the laser cutting mechanism. The free end of the vertical telescopic member 203 is fixedly installed with a transverse guide rail 204. Since the two fixing mechanisms 2 are in contact with each other, the vertical telescopic member 203 can be fixedly installed with a transverse guide rail 204. When approaching each other, they need to be dislocated, so a transverse guide rail 204 is set for transverse dislocation. A sliding table 205 that slides along the transverse guide rail 204 is fixedly installed above the transverse guide rail 204. An extension rod 206 that actively rotates is hinged above the sliding table 205. A transverse telescopic member 207 extending to both ends is fixedly installed at one end of the extension rod 206 away from the sliding table 205. A touch head 208 is fixedly installed at the free end of the transverse telescopic member 207. Through the extension and contraction of the transverse telescopic member 207, the touch head 208 is used to contact the clamped workpiece to fix the workpiece.

[0033] The bracket 1 includes a sliding pair for supporting the sliding of the laser cutting machine. A limiting groove 209 is provided at the bottom end of the base 201. A limiting beam 210 slidably connected to the inside of the limiting groove 209 is fixedly installed on the inner bottom wall of the bracket 1. A group of spring positioning heads 211 are inlaid on the inner bottom wall of the bracket 1. A card slot 212 adapted to the spring positioning head 211 is provided at the bottom end of the base 201. Through such an arrangement, the base 201 can be fixed to a specified position of the bracket 1. The two adjacent bases 201 are connected by a plug-in rod 213. The plug-in rod 213 is plugged into the inside of the slide groove for sliding connection of the sliding seat 202. The inner bottom wall of the bracket 1 The bottom wall is provided with a power mechanism 3 that drives all the bases 201 to slide as a whole. The power mechanism 3 includes a fixed plate 301, which is fixedly installed on one end of the inner bottom wall of the bracket 1. A telescopic sleeve 302 is fixedly installed on the end of the fixed plate 301 close to the base 201. The telescopic sleeve 302 is fixedly connected to the base 201 through a bracket 303. The bracket 303 is divided into a horizontal end and a plug-in end slidably connected to both sides of the horizontal end. The plug-in end is plugged into the inside of the slide groove. Through such an arrangement, the laser cutting mechanism can slide and the workpiece can also slide as a whole, thereby reducing the space required for movement.

[0034] The end face of the extension rod 206 is inlaid with a ball 214. This arrangement can utilize the ball 214 to support the sliding workpiece, which can facilitate the sliding of the workpiece. The end face of the touch head 208 is provided with a bearing hole 215, and the interior of the bearing hole 215 is slidably connected to a spring sleeve 216. The ball 214 is inlaid in the free end of the spring sleeve 216. When the workpiece contacts the touch head 208, the ball 214 can be squeezed into the interior of the bearing hole 215.

[0035] A moving mechanism 4 is provided between the base 201 and the sliding base 202. The moving mechanism 4 is also provided between the transverse guide rail 204 and the sliding platform 205. The base 201 and the transverse guide rail 204 are collectively referred to as the fixed portion, and the sliding base 202 and the sliding platform 205 are collectively referred to as the sliding portion.

[0036] The moving mechanism 4 includes a tooth groove 401 formed in the fixed portion. The bottom end of the sliding portion is rotatably connected to a gear 402 that meshes and rotates with the tooth groove 401. Friction plates 403 are provided on both sides of the bottom end of the sliding portion, which can be extended and retracted to rub against the side walls of the tooth groove 401. The friction plates 403 can be hydraulically or electrically controlled, and positioning is achieved by controlling their extension and friction against the side walls of the tooth groove 401. A motor 404 is fixedly mounted on the side wall of the sliding portion to drive the gear 402 to rotate. This technical solution can drive the moving portion to move relative to the sliding portion through the coordination of the gear 402 and the tooth groove 401, while also providing positioning through the friction plates 403.

[0037] The end face of the fixed part is fixedly mounted with a motor 405, the output end of the motor 405 is fixedly mounted with a lead shaft 406, the lead shaft 406 is threadedly connected to the sliding part, and the lead shaft 406 is rotatably connected to the fixed part. This technical solution has high positioning accuracy and does not require a friction plate 403 to fix the adjusted position.

[0038] A rotating groove 5 is provided at the top of the sliding table 205, and a motor 501 for driving the extension rod 206 to rotate is fixedly installed on the side wall of the sliding table 205. A rotating shaft 502 is fixedly installed on the output end of the motor 501, and the rotating shaft 502 is fixedly connected to the extension rod 206. A accommodating hole 503 is provided at the rotating end of the extension rod 206, and an electromagnetically controlled plug rod 504 for moving up and down is slidably connected inside the accommodating hole 503. The plug rod 213 is an electromagnetic sleeve and a magnetic ring provided at the top of the sleeve. The electromagnetic sleeve is energized to push the magnetic ring to move to achieve rising or falling. A plug hole 505 adapted to the plug rod 213 is provided on the inner bottom wall of the rotating groove 5. When the extension rod 206 rotates to be parallel to the sliding table 205, the plug rod 213 is inserted into the accommodating hole 503 under electromagnetic control. At this time, the extension rod 206 will not rotate relative to the sliding table 205 and maintain its posture.

[0039] The transverse telescopic member 207 includes two telescopic parts with free ends away from each other. The two telescopic parts are symmetrically arranged. The length of the touch head 208 is equal to the sum of the lengths of the two telescopic parts. The width of the touch head 208 is the same as the width of the telescopic parts. Through such an arrangement, it can be ensured that the two touch heads 208 can move toward each other, and the movement distance can be controlled separately, so that they can adapt to profiles of different shapes.

[0040] The vertical telescopic member 203 wraps the vertical active lifting rod 601. The fixed end of the lifting rod 601 is fixedly installed above the sliding seat 202, and the free end of the lifting rod 601 is fixedly installed below the transverse guide rail 204. The two ends of the lifting rod 601 are fixedly installed with limited sliding rods 602. The two ends of the limited sliding rod 602 are fixedly connected to the sliding seat 202 and the transverse guide rail 204 respectively. This arrangement can ensure that the lifting rod 601 will not rotate during the up and down movement.

[0041] During use, the sliding seat 202 can be adjusted relative to the base 201 through the moving mechanism 4, so that the two sliding seats 202 are adjusted to the specified position. The vertical telescopic member 203 is raised and lowered so that the workpiece can be adjusted to a height within the working range of the laser cutting machine. The horizontal telescopic member 207 can be rotated to vertical and horizontal by the relative rotation of the extension rod 206 relative to the sliding table 205. According to the shape of the profile, the horizontal telescopic member 207 is extended into the gap of the profile, and the profiles of different shapes and sizes are fixed by expanding the horizontal telescopic member 207 or bringing adjacent horizontal telescopic members 207 close to each other.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
