Abstract
The utility model relates to the field of internal thread processing, in particular to a tapping device for a common boring lathe, which is characterized in that the tapping device comprises an outer sleeve, an inner sleeve, a spring, a gripping head and a screw tap, wherein an axial sliding chute is formed on the outer surface of the inner sleeve; a slide key is arranged between the outer sleeve and the axial sliding chute; the outer sleeve and the slide key are connected through a bolt; the spring is embedded between the inner end of the inner sleeve and the outer sleeve; the gripping head is embedded at the outer end of the inner sleeve; a feather key is arranged between the gripping head and the inner sleeve; a positioning screw is arranged at the inner end of the axial sliding chute; the front end of the gripping head is connected with the screw tap; and a tail handle is arranged at the tail part of the outer sleeve. The conicity of the tail handle is matched with a boring bar of the boring lathe. Compared with the prior art, the tapping device has the benefits as follows: firstly, the tail handle is connected with the boring bar of the boring lathe, so that the tapping device solves the problem of heavy manual tapping in the production by utilizing the resultant force of rotation of a common boring lathe and the spring compression stress in the device to manufacture inner hole screw threads under the circumstance of not changing the structure of a machine tool; and secondly, the tapping device can also be suitable for other types of machine tools by changing the form of the tail handle.
Description
Technical field
The utility model relates to the internal thread machining field, relates in particular to a kind of common boring machine and uses chasing bar.
Background technology
Screw thread so that change, interchangeability well and can transmit advantage such as moment of torsion, be applied on the connector widely.Screw thread divides external screw thread and internal thread, and externally threaded processing is relatively easy, can on lathe, realize little also fine with screw die mantle fiber effect of size.But the processing of internal thread relatively just has inconvenience, because internal thread operation in the hole of workpiece, corresponding cutter receives the restriction in work piece space.Though internal thread also can obtain shaped article through the screw tap tapping; But must pay great amount of manpower realizes; The above internal thread of 50mm diameter is not only required great effort simultaneously the also time of labor through artificial moulding; Last size and positional precision also have no idea to control, so internal thread leans on the way of artificial tapping to realize having certain difficulty.
Present large-sized internal thread machining generally adopts special-purpose tapping machine, and the tapping machine equipment price is very expensive; Also have part digital-control boring-milling machine band to choose in addition and buckle function, can realize the processing request of internal thread, also need special the outfit, do not having under the said equipment situation, the internal thread machining difficult problem in the production is anxious to be solved.
Summary of the invention
The purpose of the utility model provides a kind of common boring machine and uses chasing bar, overcomes the deficiency of prior art, is not changing under the machine tool structure situation, utilizes the rotation of common boring machine and the inner hole thread of making a concerted effort to process of device inner spring compression stress.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of common boring machine is used chasing bar, comprises overcoat, interior cover, spring, chuck and screw tap, and lining the outer surface of is provided with axial slide; Be provided with slide key between overcoat and the axial slide, overcoat is connected through screw with slide key, is embedded with spring between interior cover inner end and the overcoat; Interior cover outer end is embedded with chuck, is provided with false key between chuck and the interior cover, and the axial slide inner end is provided with dog screw; The chuck front end is connected with screw tap, and the overcoat afterbody is provided with caudal peduncle.
Said caudal peduncle tapering and boring machine boring bar coupling.
Compared with prior art, the beneficial effect of the utility model is:
1) this chasing bar is connected with the boring machine boring bar through caudal peduncle, is not changing under the machine tool structure situation, utilizes the rotation of common boring machine and the inner hole thread of making a concerted effort to process of device inner spring compression stress, has solved heavy artificial mantle fiber problem in the production.
2) through changing the form of caudal peduncle, can also be applicable to the lathe of other kinds.

The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
See Fig. 1, be a kind of common boring machine of the utility model with chasing bar example structure sketch map, comprise screw tap 1, chuck 2, interior cover 3, overcoat 6, spring 8; Interior cover 3 outer surfaces are provided with axial slide 11, are provided with slide key 5 between overcoat 6 and axial slide 11 front ends, and overcoat 6 is connected through screw 4 with slide key 5; Be embedded with spring 8 between interior cover 3 inner ends and the overcoat 6; Interior cover 3 outer ends are embedded with chuck 2, are provided with false key 7 between chuck 2 and the interior cover 3, and axial slide 11 inner ends are provided with dog screw 9; Chuck 2 front ends are connected with screw tap 1, and overcoat 6 afterbodys are provided with caudal peduncle 10.Cover 3 moved along overcoat 6 straight lines in axial slide 11 made, and cover 3 can not deviate from from overcoat 6 in dog screw 9 can make,
Caudal peduncle 10 taperings and boring machine boring bar coupling.Caudal peduncle 10 structures can also be the forms that is connected with other lathe.
The use step of the utility model is following:
1) chooses suitable lathe according to the structure of overcoat caudal peduncle;
2) chasing bar is connected on the lathe rotary main shaft positioning and locking;
3) the machine tool chief axis rotation drives the chasing bar rotation, utilize the tension force of spring that interior cover is moved along overcoat, thereby screw tap is done rectilinear motion, accomplishes the tapping operation.
Claims (2)
1. a common boring machine is used chasing bar, it is characterized in that, comprises overcoat, interior cover, spring, chuck and screw tap; Lining the outer surface of is provided with axial slide, is provided with slide key between overcoat and the axial slide, and overcoat is connected through screw with slide key; Be embedded with spring between interior cover inner end and the overcoat, interior cover outer end is embedded with chuck, is provided with false key between chuck and the interior cover; The axial slide inner end is provided with dog screw, and the chuck front end is connected with screw tap, and the overcoat afterbody is provided with caudal peduncle.
