Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. Wherein the same components are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "bottom" and "top "Face", "inner" and "outer" refer to directions toward or away from, respectively, the geometric center of a particular component.

[0018] refer to Figure 1-6 As shown, a four-jaw chuck includes a chuck body 1 and jaws 2 that are slidably connected to the chuck body 1. There are four jaws 2 that are evenly distributed on the chuck body 1 in a ring shape. Above, the four claws 2 are set opposite to each other, and the sliding tracks of the four claws 2 on the chuck body 1 are arranged in a cross-shaped structure, and the intersection point of the cross-shaped sliding track and the...

Abstract

The invention discloses a four-jaw chuck with a wide application range. The technical scheme of the four-jaw chuck is characterized by comprising a chuck body and four jaws, wherein four cylinders arehinged to the chuck body and correspond to the jaws respectively, a connecting rod is connected between a piston rod of each cylinder and the corresponding jaw, the middle of each connecting rod is hinged with the chuck body, and the jaw hinged to the other end of each connecting rod can be driven to radially slide along the chuck body when each cylinder pushes the corresponding connecting rod; two kinematic pairs used for limiting a group of two jaws to slide synchronously are arranged on the chuck body; each kinematic pair comprises a turning ring rotationally connected to the chuck body, the turning ring and the chuck body are coaxially arranged, a joint lever is connected between the turning ring and the corresponding connecting rod, two ends of the joint lever are hinged with the turning ring and the corresponding connecting rod, and the same group of two cylinders can drive two jaws to synchronously slide under the guidance of the joint lever and the turning ring when pushing the connecting rods.

Description

technical field [0001] The invention relates to the field of laser cutting equipment, more specifically, it relates to a four-jaw chuck. Background technique [0002] At present, the laser pipe cutting machine is an important equipment for batch cutting and processing pipes, and the clamping chuck is an indispensable part of the laser cutting machine. The traditional clamping chuck generally adopts the principle of three-point fixed circle to clamp the shaft-shaped workpiece, so the traditional clamping chuck is more suitable for supporting round pipes, and the clamping of special-shaped pipes is currently being developed and developed , but so far there is no ideal product available. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a four-jaw chuck with a wide range of applications. [0004] In order to achieve the above object, the present invention provides the following technical solut...
