Abstract
The utility model belongs to the technical field of machining, in particular to a three-jaw chuck used for grabbing and fastening paper tubes. The three-jaw chuck comprises a rotating disc, wherein movable arms are arranged on the back face of the rotating disc, grabbing nails are arranged on the movable arms, a spring base is further arranged on the back face of the rotating disc, pressing blocks are arranged on the front face of the rotating disc, the movable arms are fixedly connected with the pressing blocks, sliding blocks are arranged on the two sides of the corresponding pressing block respectively in a tightly-attached mode, ejector rod installation sleeves are further arranged on the front face of the rotating disc, ejector rods are arranged on the ejector rod installation sleeves, and the number of the movable arms, the number of the grabbing nails, the number of the sliding blocks, the number of the ejector rods and the number of the pressing blocks are respectively three. The movable arms are combined and arranged on the rotating disc in the mode that a 120-degree included angle is formed between every two adjacent movable arms. The grabbing nails are combined and arranged on the rotating disc in the mode that a 120-degree included angle is formed between every two adjacent grabbing nails. The sliding blocks are combined and arranged on the rotating disc in the mode that a 120-degree included angle is formed between every two adjacent sliding blocks. The ejector rods are combined and arranged on the rotating disc in the mode that a 120-degree included angle is formed between every two adjacent ejector rods. The pressing blocks are combined and arranged on the rotating disc in the mode that a 120-degree included angle is formed between every two adjacent pressing blocks. Sliding grooves are formed in the movable arms, and the grabbing nails can move along the sliding grooves. The three-jaw chuck is simple in structure, convenient to detach, capable of bearing large torque and convenient to adjust.
Description
Technical field
The utility model belongs to Machining Technology field, and particularly a kind of scroll chuck, for capturing fastening paper tube.
Background technology
It is inadequate that existing claw is firmly grasped dynamics, in the time of paper tube High Rotation Speed, easily causes paper tube and claw to skid, and phase mutual friction, affects product quality, even causes scrapping of paper tube.And different because of the diameter of paper tube, when firmly grasping the paper tube of different model, existing claw need call a plurality of parts, regulates comparatively loaded down with trivial details.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of scroll chuck that captures fastening paper tube.
Technical solutions of the utility model are as follows:
A kind of scroll chuck, comprise rotating disk, the described rotating disk back side is provided with lever arm, described lever arm is provided with bitch, the back side of described rotating disk is also provided with spring base, before described rotating disk, be provided with briquetting, described lever arm is fixedly connected with briquetting, the both sides of being close to briquetting are respectively provided with slide block, before described rotating disk, be also provided with push rod installation sleeve, described push rod installation sleeve is provided with push rod, described lever arm, bitch, slide block, the number of push rod and briquetting is three, and being between any two 120 degree angle combinations is arranged on rotating disk, on described lever arm, have chute, bitch can move along this chute.
The beneficial effects of the utility model are, (1) is used bitch to thrust paper tube, when driven by motor paper tube High Rotation Speed, can bear larger torsion, and stability is good.
(2) according to paper tube size, only need to regulate the position of bitch, easy to use.
