Abstract
The utility model discloses a rapid-replacing extension-rod for a screw tap. The rapid switching rod is capable of overcoming the disadvantages of existing screw taps that the taper shank is short, the outer diameter of the drill chuck which is used to clamp the screw tap is big, and inner hole tapping near the large-diameter fringe can not be conducted; an extension rod is concentrically arranged at the other end of the rod body of the Morse taper shank on the tapping machine; the chuck which is used to clamp the screw tap is mounted on the extension-rod. As an extension-rod is arranged on the rod body, the length of the screw tap handle can be extended. When an inner tap hole is machined near the edge of the large-diameter flange, the mutual blocking and interference between the flange and the drill chuck is avoided; extension-rods with different lengths can be used to realize tapping of internal thread holes at different locations on a workpiece. If screw tap does not need extension, the member bar with an extension-rod can be removed and replaced by a drill chuck, and the operation is very easy. The tool has the advantages of simple structure, less investment, easy operation and replacement, strong interchangeability, and is capable of settling the problems which can not be overcome by the prior art, and thereby, the production efficiency is high.
Description
Technical field
The utility model belongs to outfit, the screw tap extension bar that specifically a kind of tapping is used.
Background technology
On workpiece, carry out the tapping machining internal thread,, be mostly screw tap is installed on the drill chuck of tapping machine and carry out particularly to large-scale workpiece with screw tap.Because the taper shank length of regular tap is short and small, and its length is again uncontrollable, tapping processing can also be carried out smoothly on the general big plane that does not stop on every side, if press close to large diameter during in the position as flange periphery machining internal thread hole, because the external diameter of the existing acorde bur chuck of clamping screw tap is bigger, tapping processing is often because stop interference between flange and the drill chuck external diameter, be directly installed on the drill chuck with common screw tap, only just can't directly finish herein processing with regular tap.If make the screw tap of extension bar separately, if taper shank is oversize, the influence factor that will consider at manufacture view is many, the manufacturing expense height, and all corresponding screw tap of each degree of depth of while, and can only be to a kind of screw tap of model, interchangeability is poor.
The utility model content
Technical problem to be solved in the utility model is, the taper shank length that overcomes existing screw tap is short and small, and the drill chuck external diameter of clamping screw tap is big, can't finish the shortcoming of the endoporus tapping processing at major diameter edge, and a kind of quick change extension bar of screw tap is provided.
In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: having the body of rod other end that can be installed on Morse taper shank bar on the tapping machine, be provided with lengthening with one heart and use extension bar, the chuck of clamping screw tap is installed on the extension bar.
The utility model also has following technical characterictic:
The described chuck that is installed on the extension bar is two-way chuck, form by collet body and locking nut, collet body is a hollow body, the two ends of collet body are connected with bullet respectively with one heart, the big end of bullet is relative, and along the uniform harmomegathus groove that has of chuck centerline direction, endoporus one end has two locking nuts of the conical surface on bullet, the bullet male cone (strobilus masculinus) of subtend and its adaptation is screwed on the external screw thread of collet body epicone body inboard respectively.
Advantage of the present utility model and good effect are that owing on the body of rod that can be installed on the tapping machine, be provided with to grow to add and use extension bar, the chuck that the clamping screw tap is used is installed on the extension bar, has played the effect of lengthening tap holder minister degree.When Working position is pressed close to large diameter flange periphery internal thread hole, because the extension bar screw tap that extended is arranged, avoided prior art flange and drill chuck to stop the phenomenon of interference, change the extension bar of different length, just can adapt on the workpiece on the diverse location the requirement of internal thread hole tapping processing, be applicable to that the tapping on the internal thread hole position that the various edges of workpiece interfere with drill chuck is easily processed.If screw tap does not need lengthening, unload the body of rod of band extension bar, it is very convenient to recover the original drill chuck that uses.Above-mentioned tool construction is simple, and small investment uses replacing convenient, and interchangeability is strong, has solved the insurmountable problem of prior art, the production efficiency height.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the shape assumption diagram that connects chuck among Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Among Fig. 1, at the left end of the body of rod 1, be provided with the Morse taper shank 1.2 that can be installed on the tapping machine, the right-hand member of the body of rod 1 is provided with lengthening with one heart with extension bar 1.1, and the chuck that can be connected with extension bar 1.1 with clamping screw tap 5 is installed on the extension bar 1.1.
The described chuck that is installed on the extension bar 1.1 is two-way chuck, left end is an extension bar chuck 3.1, right-hand member is a tap chuck 3.2, chuck is made up of collet body 3 and locking nut, collet body 3 is a hollow body, the two ends of collet body 3 are respectively equipped with the relative bullet of big end, on two bullets, along the uniform respectively harmomegathus groove 3.11 and 3.21 (referring to Fig. 2) that has of chuck centerline direction, one end endoporus has and bullet adapt the extension bar binding nut 2 and the screw tap binding nut 4 of the conical surface, the male cone (strobilus masculinus) 3.12 and 3.22 of subtend two bullets is screwed on the external screw thread 3.13 and external screw thread 3.23 of bullet inboard respectively.
Owing on the bullet at hollow collet body 3 two ends harmomegathus groove 3.11 and 3.21 are arranged, when tightening extension bar binding nut 2 and screw tap binding nut 4, because hollow collet body 3 two ends have the bullet of harmomegathus groove 3.11 and 3.21, make slightly elasticity of collet body 3 two ends, extension bar binding nut 2 and screw tap binding nut 4 inwardly draw male cone (strobilus masculinus) 3.12 and 3.22 in, the screw tap 5 of extension bar 1.1 and different-diameter can be clamped, the clamping scope is big, and interchangeability is strong; Unscrew screw tap binding nut 4, can change screw tap 5 at any time, quick and easy to use, clamping is reliable.
