In order to overcome defects, the invention provides a kind of interior swollen type spring chuck, this spring chuck is not only simple in structure, but and clamped one time realize the processing of the both ends of the surface of product, thereby guarantee processing dimension and position degree, Improving The Quality of Products.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of interior swollen type spring chuck, described spring chuck comprises chuck body and tensioner, described chuck body one end is formed for seizing on both sides by the arms the holding part in lathe, the other end is formed for inserting the insertion section of processed product endoporus, and the endoporus side view of the lateral surface shape of this insertion section and processed product is complementary; Be formed for processing the empty avoiding section of hole end surface in the processed product between described holding part and the insertion section, and the section radius of this empty avoiding section is respectively less than the section radius of described holding part and insertion section; Be that the center, insertion section forms a cavity along its axis in the other end of described chuck body, this cavity is opened on the end of described insertion section, and an end of described tensioner places in the cavity of this insertion section by screw-threaded engagement; Lateral surface in the insertion section of described chuck body is formed with several tension force grooves along its axis direction, and this tension force trench bottom is communicated with described cavity; The other end of described tensioner can be placed in the endoporus of described processed product.During use, first the threaded end of tensioner is inserted in the cavity of chuck body insertion section, screw a little tensioner, then this clamping body insertion section and the tensioner other end are inserted in the endoporus of processed product together, then the clamping part of stationary fixture body, screw the screw thread between tensioner and the anchor clamps, because the chuck body insertion section is provided with several tension force grooves, this tension force groove outwards opens under the effect of tensioner and pushes simultaneously processed product endoporus medial surface, until chuck body clamps processed product, like this, two end faces and endoporus that just can be towards processed products processed respectively, thereby realize that clamped one time finishes the processing to product both ends of the surface and endoporus, save the clamping time, raising efficiency, and guarantee processing dimension and position degree, Improving The Quality of Products.
As a further improvement on the present invention, on the lateral surface of the insertion section of described chuck body, be circumferentially with some grooves along it, can increase the frictional force between chuck body and the product, be conducive to being fixedly clamped of product.
As a further improvement on the present invention, described tension force groove is six, and is symmetrically distributed on the lateral surface of insertion section of described chuck body.
As a further improvement on the present invention, the holding part of described clamping body and empty avoiding section are all cylindrical.
As a further improvement on the present invention, described tension force groove extends in the empty avoiding section of described chuck body.
As a further improvement on the present invention, described tensioner one end is cylindrical, and be evenly equipped with screw thread on its lateral surface, the end that the other end of this tensioner closes on this cylindrical end forms a vertical contact-making surface, is provided with back-up ring between the vertical contact-making surface of this tensioner and described chuck body.
The invention has the beneficial effects as follows: the endoporus by swollen type spring chuck and processed product in this carries out clamping and positioning, and then this spring chuck is fixed on the lathe, clamped one time can be realized the processing of product two sides, save the clamping time, raising efficiency, and assurance processing dimension and position degree, Improving The Quality of Products.
