[0025] This utility model provides a chuck structure and a three-chuck laser tube cutting device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0026] Please see Figure 1 and Figure 2This utility model provides a chuck structure, including a side bracket 21, a drive mechanism 22 disposed on the side bracket 21 and used to drive the side bracket 21 to reciprocate along the length direction of the bed 1, and a clamping chuck 23 disposed on the side bracket 21; both the clamping chuck 23 and the side bracket 21 are provided with mounting holes 231 extending front and rear, and mounting screws (not shown in the figure) are disposed in the mounting holes 231; first auxiliary mounting blocks 2131 are respectively disposed above and below the clamping chuck 23, and the first auxiliary mounting blocks 2131 are provided with through-holes. The first threaded hole 2132 on each of the lower two side walls is threaded with a first push rod (not shown in the figure), which is used to press against the upper or lower surface of the clamping chuck 23; the left and right sides of the clamping chuck 23 are respectively provided with a second auxiliary mounting block 2133, which is provided with a second threaded hole 2134 penetrating its left and right side walls, and a second push rod (not shown in the figure) is threaded into the second threaded hole 2134, which is used to press against the left or right side wall of the clamping chuck 23.

[0027] When the above-mentioned chuck structure 2 needs to be installed, a crane / crane is used to lift the clamping chuck 23 to the outside of the side bracket 21, and the clamping chuck 23 is brought close to the side bracket 21. The first push rod is gradually screwed into the corresponding first threaded hole 2132 on the side bracket 21, and the second push rod is gradually screwed into the corresponding second threaded hole 2134 on the side bracket 21, so that the ends of the first push rod and the second push rod body abut against the corresponding side wall of the clamping chuck 23. By turning the first push rod and the second push rod one by one, the position of the mounting hole 231 on the clamping chuck 23 corresponding to the mounting hole 231 on the side bracket 21 is finely adjusted by changing the screwing degree of the first push rod and the second push rod body, until the mounting hole 231 of the clamping chuck 23 is coaxial with the mounting hole 231 on the side bracket 21. Then the mounting screws can be screwed into the mounting holes 231 of the clamping chuck 23 and the side bracket 21 one by one.

[0028] The chuck structure 2 described above, by setting a first auxiliary mounting block 2131 and a second auxiliary mounting block 2133 on the outside of the side bracket 21, and opening threaded holes on the corresponding auxiliary mounting blocks, utilizes the change in the screwing degree of the push rod body set in the threaded holes to finely adjust the position of the mounting hole 231 on the clamping chuck 23 relative to the mounting hole 231 of the side bracket 21, so as to facilitate the installation of the clamping chuck 23 onto the side bracket 21 and improve the installation accuracy of the clamping chuck 23.

[0029] In some embodiments, the second auxiliary mounting blocks 2133 are arranged in multiple sets vertically, and the second push rods on the multiple sets of second auxiliary mounting blocks 2133 are all used to press against the left or right side wall of the clamping chuck 23. Since the clamping chuck 23 is relatively high, the multiple sets of vertically arranged second auxiliary mounting blocks 2133 are used to adjust the levelness of each position in the height direction of the clamping chuck 23 one by one, reducing the difficulty of aligning the mounting holes 231 on the clamping chuck 23 with the mounting holes 231 on the side bracket 21.

[0030] Please see Figure 1 In some embodiments, the side bracket 21 includes a first mounting frame 211, a second hanging plate 212 fixedly connected to the rear side wall of the first mounting frame 211, and a third hanging bracket 213 fixedly connected to the second hanging plate 212. The clamping chuck 23 is disposed on the third hanging bracket 213. Specifically, the first mounting frame 211 is horizontally arranged, and the drive mechanism 22 is disposed on the first mounting frame 211. The second hanging plate 212 is vertically arranged with respect to the first mounting frame 211, and the third hanging bracket 213 is vertically arranged with respect to the second hanging plate 212, so that the entire side bracket 21 is Z-shaped to adapt to the shape of the bed 1.

[0031] Please see Figure 1 and Figure 2 In some embodiments, first adjusting blocks 2121 are respectively provided above and below the third bracket 213. The first adjusting blocks 2121 have first screw holes 2122 penetrating their upper and lower side walls, and first adjusting rods are threaded into the first screw holes 2122. The first adjusting rods are used to press against the upper or lower surface of the third bracket 213. Second adjusting blocks 2123 are respectively provided on the left and right sides of the third bracket 213. The second adjusting blocks 2123 have second screw holes 2124 penetrating their left and right side walls, and second adjusting rods are threaded into the second screw holes 2124. The second adjusting rods are used to press against the left or right side wall of the third bracket 213. When the third bracket 213 needs to be assembled onto the outer surface of the second mounting plate 212, the position of the third bracket 213 is finely adjusted by changing the screw-in degree of each adjusting rod body, so that the positions of the multiple mounting holes 231 on the third bracket 213 are aligned one by one with the corresponding mounting holes 231 on the second mounting plate 212.

[0032] Please see Figure 1In some embodiments, the first adjusting blocks 2121 are arranged in multiple sets on the left and right sides, and the first adjusting rods on the multiple sets of first adjusting blocks 2121 are all used to press against the upper or lower surface of the third bracket 213; the second adjusting blocks 2123 are arranged in multiple sets on the top and bottom, and the second adjusting rods on the multiple sets of second adjusting blocks 2123 are all used to press against the left or right side wall of the third bracket 213. The third bracket 213 is relatively large, and by using multiple sets of left and right first adjusting blocks 2121 and multiple sets of top and bottom second adjusting blocks 2123, the various positions of the third bracket 213 can be finely adjusted.

[0033] Please see Figure 1 In some embodiments, a distance measuring mechanism 24 is provided on the side bracket 21, which is used to contact the end of the pipe. In this solution, the distance measuring mechanism 24 is used to contact the right end of the pipe. Specifically, the drive mechanism 22 moves the distance measuring mechanism 24 towards the right end of the pipe. According to the program settings, after the chuck structure 2 moves to the set position, the distance measuring mechanism 24 operates and contacts the right end of the pipe to measure the distance from the chuck structure 2 to the right end of the pipe. This ensures that the chuck structure 2 can accurately clamp the right end of the pipe, avoiding the occurrence of empty clamping of the pipe.

[0034] Please see Figure 3 In some embodiments, the ranging mechanism 24 includes a cylinder 241 with its cylinder body mounted on the side bracket 21 and its output end aligned with the extension direction of the pipe; a moving plate 242 mounted on the output end of the cylinder 241; a stroke sensor 243 mounted on the moving plate 242; and a touch plate 244 mounted on the stroke sensor 243. The stroke sensor 243 is located on the side wall of the moving plate 242 facing the pipe. Specifically, when the output end of the cylinder 241 operates, it drives the moving plate 242 and the stroke sensor 243 to move towards the right end of the pipe. When the touch plate 244 on the stroke sensor 243 contacts the right end of the pipe, the touch plate 244 acts on the stroke sensor 243. The stroke sensor 243 transmits the movement stroke to the control mechanism via an electrical signal. After calculation, the distance from the right end of the pipe to the clamping chuck 23 is determined. Then, the driving mechanism 22 moves the clamping chuck 23 to ensure that the clamping chuck 23 accurately clamps the right end of the pipe.

[0035] Please see Figure 3In some embodiments, guide sleeves 245 are respectively provided on both sides of the cylinder 241. A guide rod 246 parallel to the extension / retraction direction of the cylinder 241's output end is provided within each guide sleeve 245. The end of the guide rod 246 is fixedly connected to the side wall of the moving plate 242. The guide sleeves 245 and guide rods 246 ensure the smooth movement of the stroke sensor 243 and the touch plate 244 at the cylinder 241's output end, thereby avoiding the impact of vibration on the accuracy of the movement distance measurement.

[0036] Please see Figure 1 In some embodiments, the side bracket 21 is provided with a collision protection seat 25 on the side wall facing the adjacent chuck structure, and the collision protection seat 25 is provided with a collision protection rubber 251 on the side wall facing the adjacent chuck structure. Specifically, each chuck structure on the pipe cutting equipment is provided with a collision protection seat 25 on its side wall, and the collision protection seat 25 is provided with a collision protection rubber 251. Therefore, even if the movement trajectory of the chuck structure overlaps due to sensor malfunction or program error, only the collision protection seat 25 collides with the adjacent collision protection rubber 251, which can protect each chuck structure.

[0037] Please see Figure 4 This utility model also provides a three-chuck laser tube cutting device, including a bed 1, a chuck structure 2, a second chuck structure 3, and a third chuck structure 4 that can reciprocate along the length of the bed 1, a gantry frame 11 mounted on the bed 1, and a laser cutting assembly 5 mounted on the gantry frame 11. After the tube is loaded, it is clamped by the chuck structure 2 and the second chuck structure 3 and pushed towards the laser cutting assembly 5. After processing and cutting by the laser cutting assembly 5, the tube is cut into tubes of the corresponding length, and then clamped and unloaded by the third chuck structure 4.
