DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

Please refer to Figures 1-3. The utility model relates to a pipe clamping chuck for laser cutting. The pipes mentioned in this application include round pipes and square pipes. The preferred embodiments of the utility model will be described in detail below in conjunction with the drawings in the specification. The clamping chuck includes a fixed seat 01, on which a mounting plate 02 is vertically fixedly mounted, and a notch 03 for the pipe to pass through is arranged in the middle of the mounting plate 02. A chuck seat 04 is fixedly mounted on the mounting plate 02, and a through hole connected to the notch 03 is arranged in the center of the chuck seat 04. A claw device for clamping the pipe is arranged on the chuck seat 04. A driving device for driving the claw device to move in the radial direction of the chuck seat 04 is arranged in the chuck seat 04. A mounting hole 05 coaxially arranged with the through hole is arranged in the chuck seat 04, and the driving device is installed in the mounting hole 05. The driving device comprises a fixing ring 06 fixedly mounted on the mounting plate 02, a gear ring 07 is rotatably mounted on the fixing ring 06, a driving motor 08 is fixedly mounted in the fixing seat 01, a driving gear 09 is fixedly mounted on the output end of the driving motor 08, and the driving gear 09 is meshed and connected with the gear ring 07. A spiral disk 10 is fixedly mounted on the gear ring 07. A spiral groove 11 is provided on the spiral disk 10. Two groups of mutually perpendicular horizontal card groups and vertical card groups with the same structure are arranged on the spiral groove 11, and the horizontal card group includes two claws 12 with the same structure, and the two claws 12 are arranged relative and symmetrically. A slide groove 13 for the claws 12 to move toward the center of the chuck seat 04 is provided on the chuck seat 04. When in use, the driving motor 08 is started, and the driving motor 08 drives the gear ring 07 to rotate on the fixing ring 06. When the gear ring 07 rotates, the spiral disk 10 rotates with it, so that the four claws 12 on the spiral groove 11 move synchronously along the slide groove 13 toward the center direction of the chuck seat 04 or move away from the center direction. Thereby achieving the effect of synchronously driving the four claws 12.

To ensure that the claw 12 moves smoothly and linearly in the slide groove 13, guide grooves 14 are set on both sides of the slide groove 13, and guide plates 15 adapted to the guide grooves 14 are set on both sides of the claw 12. A cross roller guide rail is fixedly installed between the guide plate 15 and the bottom of the guide groove 14.

The clamping device includes a transverse clamping part and a longitudinal clamping part arranged perpendicularly to the transverse clamping part, and the transverse clamping part is located directly below the longitudinal clamping part. The transverse clamping part includes two transverse rollers 16 symmetrically arranged on the chuck seat 04, and a connecting seat 17 is fixedly installed on the transverse roller 16, and the connecting seat 17 is fixedly connected to the clamping claw 12 of the transverse clamping group. The transverse roller 16 is slidably connected to the chuck seat 04 through a linear guide rail. When the two clamping claws 12 on the transverse clamping group move, the two transverse rollers 16 are driven to move respectively. The longitudinal clamping part includes two support seats 20 symmetrically installed on the chuck seat 04, and the transverse roller 16 is located directly below the support seat 20. Two longitudinal rollers 18 with the same structure as the transverse roller 16 are symmetrically arranged on the support seat 20, and the longitudinal roller 18 is slidably connected to the support seat 20 by a sliding guide rail. A fixing rod 19 is fixedly installed on the longitudinal roller 18, and the fixing rod 19 is fixedly installed on the clamping claw 12 of the vertical clamping group. Similarly, when the two claws 12 of the two vertical clamping groups move, they respectively drive the two longitudinal rollers 18 to move. Since the four claws 12 are synchronous in the process of moving, they are synchronous in the process of driving the transverse roller 16 and the longitudinal roller 18.

The longitudinal roller 18 includes a roller seat 21 slidably connected to a support seat 20, and two rollers 22 are arranged in parallel in the roller seat 21. Both ends of the rollers 22 are rotatably mounted in the roller seat 21 through bearings. The arrangement of the rollers 22 can ensure that the pipe can move forward and backward and can also clamp the pipe.
