Description

Technical Field

[0001] The utility model belongs to the technical field of laser tube cutting machines, and in particular relates to a front chuck for clamping special-shaped tubes used in laser tube cutting machines. Background Art

[0002] Laser cutting machine is to focus the laser emitted from the laser into a high power density laser beam through the optical path system.

[0003] The chuck cylinder on the market currently has a long stroke and swings, which occupies a large space inside the chuck, resulting in a large outer diameter of the front chuck and a large inertia. The energy consumption is large, the speed is slow, and the cutting efficiency is low. The cylinder swings with a large load and has a short working life.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

When the transmission component 5 rotates, it can drive the clamping component 6 meshed with the surface to move, so that it can clamp and fix the special-shaped pipe during the movement. The driving component 4 is fixedly installed, and a double driving source is used between its output end and the transmission component 5, thereby ensuring the stability of the driving component 4 during the working process, and can effectively reduce the internal occupied space of the installation component 3, thereby achieving the purpose of small diameter of the installation component 3, so that it has small inertia, fast rotation speed, high cutting efficiency, and low energy consumption. The cylinder has a long service life.

[0042] In one embodiment, for the above-mentioned rotating component 2, the rotating component 2 includes a fixed frame 201, one side of the fixed frame 201 is fixedly installed with one side of the mounting frame 1, a motor 202 is fixedly installed on one side of the fixed frame 201, a driving gear 203 is fixedly installed on the output end of the motor 202, a driven gear ring 204 is meshedly provided on the surface of the driving gear 203, a mounting sleeve 205 is fixedly installed inside the driven gear ring 204, and one side of the mounting sleeve 205 is fixedly installed with one side of the mounting component 3.

When the driving gear 203 rotates, it can drive the driven gear ring 204 meshing on its surface to rotate. When the driven gear ring 204 rotates, it can drive the mounting sleeve 205 fixedly installed inside it to rotate. Since the outer surface of the mounting sleeve 205 is rotated with the internal rotation of the mounting frame 1, it can rotate with the mounting frame 1 as the center of the circle, and at the same time, it can drive the mounting component 3 fixedly installed on one side to rotate, thereby providing rotational power for the mounting component 3.

When the connecting plate 403 moves, it can drive the two groups of first racks 404 fixedly installed on one side thereof to move. Since the surfaces of the two groups of first racks 404 are meshed with the surface of the transmission component 5, when the first racks 404 move, they can drive the transmission component 5 meshed with the surface thereof to operate, thereby providing stable power for the transmission component 5.

[0052] A clamping block 604 is fixedly mounted on the top of the moving block 602 , and a clamping roller 605 is rotatably arranged inside the clamping block 604 .

[0053] When the driven gear 503 rotates with the rotation of the rotating shaft 501, it can drive the second rack 603 meshing on its surface to move. When the second rack 603 moves, it can drive the moving block 602 fixedly installed on one side to move. Since the outer surface of the moving block 602 is slidably arranged with the inner side of the fixed block 601, when the moving block 602 moves, it can move along the direction of the fixed block 601.

[0055] The arrangement of two sets of bearings 8 can limit one side of the two sets of first racks 404, thereby ensuring stable meshing between the surface of the first rack 404 and the surface of the transmission gear 502, thereby improving the stability of the front chuck for clamping special-shaped tubes for the laser tube cutting machine.

[0056] Through the above technical solution, 1. By starting the driving component 4, the transmission component 5 meshing with the output end can be driven to rotate. When the transmission component 5 rotates, the clamping component 6 meshing with the surface can be driven to move, so that the special-shaped pipe can be clamped and fixed during the movement.
