Abstract
The utility model discloses a transitional jacket for boring cutters. The transitional jacket is a cylindrical sleeve with the outer side having a step structure. An opened through groove is axially arranged on the sleeve, the joint end face of the large outer-diameter end and the small outer-diameter of the sleeve is an axial locating face, and pairs of scribed lines are arranged on a calibration face. An elongated through hole is arranged at the small outer-diameter end of the sleeve, and the central line along the length direction of the elongated through hole is identical with the central line along the length direction of the opened through groove. A flat surface parallel to the axial line of the sleeve is cut on the outer lateral face of the small diameter end of the sleeve. The transitional jacket for the boring cutters can be used without being limited by the position of a pressure thread hole on a boring cutter seat or by the shape of a boring cutter, the clamping strength of the boring cutter is increased, and simultaneously the previous preparation time is greatly shortened. Simultaneously, the transitional jacket for the boring cutters is not only suitable for installation of various boring cutters, but also suitable for installation of tools including various drills, milling cutters, reamers and the like, and meets various requirements for manufacturing of a numerical control machine.
Description
Technical field
The utility model relates to boring cutter transition chuck, relates in particular to a kind of boring cutter transition chuck that is used on the Digit Control Machine Tool.
Background technology
In machine-building; The cut of Digit Control Machine Tool runs into and will carry out boring processing to the hole of part through regular meeting; This type of part be processed in that the difference according to processed hole has different selections when selecting process tool; Common irony boring cutter, whole hard alloy boring cutter or shockproof boring cutter are generally arranged, and various boring cutters need use different transition chucks when mounted.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of versatility good boring cutter transition chuck, can satisfy the requirement when mounted of various boring cutters.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of boring cutter transition chuck; This transition chuck is the cylindrical sleeve that the outside is provided with the single order ledge structure; The diameter of the endoporus of said sleeve and boring cutter handle of a knife size are complementary, and are axially arranged with the opening groove along sleeve, and the end face that big external diameter end of said sleeve and the little external diameter end of sleeve join is an axial locating surface; The big external diameter end of sleeve is the rectifying plane that the position of boring cutter is proofreaied and correct with the end face that the little external diameter end of sleeve deviates from mutually; On rectifying plane, be provided with paired groove, said two paired grooves point-blank, and this straight line passes the positive center of circle; Be provided with long waist type open-work at the little external diameter end of sleeve, and the center line of this long waist type open-work length direction is consistent with the center line of opening groove length direction; On the lateral surface of the little external diameter end of sleeve, cut a flat horizontal surface that is parallel to sleeve axis, this flat horizontal surface becomes plumbness with groove on the rectifying plane.
The opening groove can increase the elasticity of transition chuck, realizes with arc surface mode clamping boring cutter; Axial locating surface can realize that transition clamp is enclosed within the axial location on the bore hole tool rest; The design that transition clamp puts groove centering carbide alloy boring cutter or shockproof boring cutter nose center easily and fast is high.
When being used for the installation of whole hard alloy boring cutter or shockproof boring cutter; At first in the endoporus with boring cutter injection transition chuck; And the groove on the boring cutter handle of a knife is alignd with the groove that transition clamp puts; The push type broach screwed hole that runs through on the bore hole tool rest through the push type broach screw is pressed on the flat horizontal surface of transition chuck, and boring cutter is fixed in the tool rest on the lathe.When being used for the installation of common irony boring cutter; At first in the endoporus with boring cutter injection transition chuck; And the flat horizontal surface on the boring cutter is aimed at the long waist type open-work that transition clamp puts; Run through the long waist type open-work that push type broach screwed hole and transition clamp on the bore hole tool rest put through the push type broach screw and be pressed on the flat horizontal surface of boring cutter, boring cutter is fixed in the tool rest on the lathe.
Be provided with one along its circumferential undercut groove in little external diameter end of sleeve and big external diameter end joint, the side and the axial locating surface of said undercut groove are positioned on same; The design of undercut groove can make things convenient for the grinding of the cylindrical and the locating surface of whole transition chuck.
Beneficial effect: the boring cutter transition chuck that the utility model provides; It uses and does not receive the restriction of the push type broach screwed hole position on the bore hole tool rest; Nor receive the restriction of boring cutter form, in the grip strength that has increased boring cutter, also shortened the machined early-stage preparations time greatly; Simultaneously, it is not only applicable to the installation of various boring cutters, can also be applicable to the installation of cutters such as various drill bits, milling cutter, reamer, has satisfied the various process requirements of Digit Control Machine Tool, and versatility is good.
Description of drawings
Fig. 1 is the structural representation of facing of the utility model;
Fig. 2 is the right TV structure sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
As Fig. 1, shown in Figure 2 be a kind of boring cutter transition chuck; This transition chuck is the cylindrical sleeve that the outside is provided with the single order ledge structure; The diameter of the endoporus 5 of said sleeve and boring cutter handle of a knife size are complementary, and are axially arranged with opening groove 4 along sleeve, and the end face that big external diameter end of said sleeve and the little external diameter end of sleeve join is an axial locating surface 1; The big external diameter end of sleeve is the rectifying plane that the position of boring cutter is proofreaied and correct with the end face that the little external diameter end of sleeve deviates from mutually; On rectifying plane, be provided with paired groove 6, said two paired grooves 6 point-blank, and this straight line passes the positive center of circle; Be provided with long waist type open-work 3 at the little external diameter end of sleeve, and the center line of these long waist type open-work 3 length directions is consistent with the center line of opening groove 4 length directions; On the lateral surface of the little external diameter end of sleeve, cut a flat horizontal surface 7 that is parallel to sleeve axis.
Be provided with one along its circumferential undercut groove 2 in little external diameter end of sleeve and big external diameter end joint, the side and the axial locating surface 1 of said undercut groove 2 are positioned on same.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
