Description

Technical Field

[0001] This utility model relates to the technical field of chuck mechanisms, and in particular to a centering and pulling chuck mechanism. Background Technology

[0002] A chuck mechanism is a common mechanical clamping device, mainly used for clamping, fixing and releasing workpieces. A chuck mechanism is a part in a mechanical structure used to clamp and hold workpieces, or a machine tool accessory used to clamp and position workpieces.

[0003] Existing chuck mechanisms, such as the prior art with application number CN201910364314.2, include a positioning detection component, a chuck guide rail, a drive component, a drive motor, a ball screw module, a first slider, a second slider, a drive cylinder, a piston rod, a first chuck, a first chuck tooth, and a first connecting arm. By setting a sliding chuck guide rail, the position of the chuck guide rail can be adjusted to adjust the position of the component formed by the first chuck and the second chuck. Furthermore, the relative position between the first chuck and the second chuck can be adjusted independently, allowing the chuck to clamp workpieces of different shapes and sizes at different positions.

[0004] When laser cutting steel pipes, after fixing one end of the steel pipe, the existing technology makes it difficult to correct and center the steel pipe using clamps, which in turn affects the accuracy of laser cutting of steel pipes. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a centering and pulling chuck mechanism that facilitates the centering and correction of steel pipes, improves practicality and the quality of steel pipe processing.

[0006] This utility model discloses a centering and pulling clamping mechanism, including a main mounting plate; it also includes a guiding mechanism, a centering drive mechanism, a counter-centering auxiliary mechanism, a centering mechanism, and a clamping mechanism. The centering drive mechanism is mounted on the guiding mechanism, the counter-centering auxiliary mechanism is mounted on the centering drive mechanism, the centering mechanism is mounted on the centering drive mechanism, and the clamping mechanism is mounted on the centering drive mechanism. The guiding mechanism guides the centering drive mechanism, the counter-centering auxiliary mechanism assists the centering drive mechanism in driving the centering mechanism to center and correct the steel pipe, and the clamping mechanism can clamp and fix the steel pipe. The counter-centering auxiliary mechanism assists the centering drive mechanism in sliding opposite directions on the guiding mechanism, thereby facilitating the centering mechanism to center and correct the steel pipe, improving the accuracy of laser cutting of the steel pipe, and the clamping mechanism can clamp and fix the steel pipe, facilitating the feeding of the steel pipe and improving practicality.

[0007] Preferably, the guiding mechanism includes a slide rail and two sets of sliders. The main mounting plate is mounted on the external moving part, the slide rail is mounted on the bottom end of the main mounting plate, and the two sets of sliders are slidably mounted on the slide rail. By having the two sets of sliders slide on the slide rail, it is convenient for the auxiliary centering mechanism to correct and center steel pipes of different diameters, thereby improving the accuracy of laser cutting of steel pipes.

[0008] Preferably, the centering drive mechanism includes a first moving arm, a second moving arm, and a first cylinder. The first and second moving arms are mounted on two sliders, and the first cylinder is mounted on the bottom end of the main mounting plate. The movable end of the first cylinder is connected to the first moving arm. By opening the first cylinder, the slider on the first moving arm slides on the slide rail. With the assistance of the opposing auxiliary mechanism, the first and second moving arms move relative to each other with the help of the sliders, thereby assisting the centering mechanism in correcting and centering steel pipes of different diameters and improving the accuracy of laser cutting of steel pipes.

[0009] Preferably, the opposing auxiliary mechanism includes a first rack, a second rack, and a gear shaft. The first rack is mounted on a first moving arm, the second rack is mounted on a second moving arm, and the gear shaft is rotatably mounted on the bottom end of the main mounting plate via a rotating shaft. Both the first and second racks mesh with the gear shaft. By opening the first cylinder, the slider on the first moving arm slides on the slide rail. The meshing relationship between the first and second racks and the gear shaft drives the gear shaft to rotate, thereby causing the first and second moving arms to move relative to each other with the assistance of the slider. This drives the centering mechanism to correct and center steel pipes of different diameters, improving the accuracy of laser cutting of steel pipes.

[0010] Preferably, the centering mechanism includes multiple centering frames and multiple centering rollers. The multiple centering frames are mounted on the first moving arm and the second moving arm, and the centering rollers are rotatably mounted on the centering frames. By opening the first cylinder, the slider on the first moving arm slides on the slide rail. The meshing relationship between the first rack and the second rack and the gear shaft drives the gear shaft to rotate, thereby causing the first moving arm and the second moving arm to move relative to each other with the assistance of the slider. This drives the centering rollers to correct and center steel pipes of different diameters, improving the accuracy of steel pipe laser cutting. The rotation of the centering rollers makes it easier to keep the laser cutting head in the center position of the steel pipe when the steel pipe is moved axially, thus improving the quality of steel pipe cutting.

[0011] Preferably, the gripper mechanism includes two rotating arms, two pins, two second cylinders, and two material-pulling grippers. The middle of the two rotating arms is rotatably mounted on the first and second moving arms, and the two pins are rotatably mounted on both ends of the two rotating arms. The two rotating arms are symmetrically mounted. The two second cylinders are rotatably mounted on the first and second moving arms, and the movable ends of the two second cylinders are rotatably mounted on the pins. The two material-pulling grippers are mounted on the other end of the rotating arms. When it is necessary to grip and fix the steel pipe for feeding, the two second cylinders are opened to push the two pins to rotate, thereby driving the material-pulling grippers to fix and clamp the steel pipe.

[0012] Preferably, the two material pulling claws are equipped with clamping teeth; the clamping teeth on the material pulling claws improve the stability of the gripping.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the opposing auxiliary mechanism assists the centering drive mechanism to slide opposite to each other on the guide mechanism, thereby facilitating the centering mechanism to center and correct the steel pipe, improving the accuracy of laser cutting of steel pipe; the clamping mechanism can clamp and fix the steel pipe, facilitating the feeding of steel pipe and improving practicality.

[0030] like Figures 1 to 5 As shown, the centering and pulling claw mechanism includes a main mounting plate 11, a guide mechanism 01, a centering drive mechanism 02, an opposing auxiliary mechanism 03, a centering mechanism 04, and a gripper mechanism 05.

[0036] The two material pulling claws 54 are equipped with clamping teeth 61;

[0037] The opposing auxiliary mechanism 03 assists the centering drive mechanism 02 to slide opposite to each other on the guide mechanism 01, thereby facilitating the centering mechanism 04 to center and correct the steel pipe, improving the accuracy of laser cutting of the steel pipe. When the steel pipe needs to be gripped and fixed for feeding, the two second cylinders 53 are opened to push the two pins 52 to rotate, thereby driving the pulling claw 54 to fix and clamp the steel pipe. The pulling claw 54 is equipped with clamping teeth 61 to improve the stability of gripping, facilitate the feeding of the steel pipe, and improve practicality.

[0038] like Figures 1 to 5 As shown, the centering and pulling gripper mechanism of this utility model, when in operation, drives the slider 13 on the first moving arm 21 to slide on the slide rail 12 by opening the first cylinder 23.
