The invention discloses a chuck, which comprises a base; the upper end of the base is connected with a sliding seat; the sliding seat is respectively connected with a left sliding plate and a right sliding plate in a sliding way; and ends at two sides of the sliding seat are connected with sliding seat end plates; through holes are formed in the middle of the sliding seat end plates and are internally provided with lead screws in a rotating way; left threads and right threads are respectively arranged at two sides of the lead screws; a left nut and a right nut are correspondingly arranged, and the left nut is fixedly connected with the left sliding plate; the right nut is fixedly connected with the right sliding plate; jack catches are arranged on the left sliding plate and the right sliding plate and are of V-shaped structure; jack catch inner base plates are installed at two inner sides of each jack catch; and jack catch outer base plates are installed at two outer sides of each jack catch. According to the invention, the jack catches arranged on the chuck are of the V-shaped structure; when clamping, the two jack catches can lead four points to contact a work piece and realize good fastening effect; the jack catch inner base plates and the jack catch outer plates arranged on the jack catches are all made of copper; and in the way, and the chuck can effectively avoid damage to the work piece when clamping, and is simple in structure and easy to implement.
Description
technical field [0001] The invention relates to a chuck. Background technique [0002] Some chucks need to be used to clamp the workpiece on some welding workbenches, and two-jaw and three-jaw self-centering chucks are commonly used. At present, when the existing two-jaw chuck clamps a larger workpiece, because it only relies on two points to clamp the workpiece, its fastening effect is poor and cannot effectively clamp; while the three-jaw chuck that can clamp a larger workpiece Jaw chucks are often expensive and easy to damage the surface of the workpiece. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a chuck which has the characteristics of simple structure, easy implementation, effective clamping of large-sized workpieces, and less damage to the surface of the workpiece. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] A chuck, comprisi...
