Description

Automatic tapping device of lathe

Technical Field

The utility model relates to a chasing bar especially relates to an automatic chasing bar of lathe.

Background

The civil air defense door is civil air defense equipment used for protecting personnel or material equipment in civil air defense engineering from being safe when a nuclear weapon, a conventional weapon or a biochemical weapon explodes in wartime, mainly plays a role in preventing shock waves, fragments and toxic gases, and has performance indexes mainly including resistance grade and sealing performance.

In the production process of the civil air defense door, the machining of the locking part needs to be carried out with thread machining, namely tapping. At present, two methods are used for machining threads: when threads are machined on a lathe, a threading tool is selected, change gears and feeding parameters are adjusted, and finally the main shaft is adjusted to rotate forwards and backwards to machine the threads by using transmission mechanisms such as a lead screw, a split nut and the like; tapping is performed manually using dies and a die wringing bar. The two types of threads are complex in machining operation, not beneficial to quality control and not easy to master, operators are easy to fatigue during batch machining, accidents of collision are easy to happen, manual operation efficiency is low, time and labor are wasted, and the threads are not suitable for batch machining.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an complex operation when aiming at present processing screw thread, it is inefficient, waste time and energy, and there is the problem of potential safety hazard during the threading, provided an automatic tapping device of lathe, utilize this device to improve work efficiency with quick processing screw thread, be applicable to the processing of screw thread in batches.

In order to realize the above object, the utility model provides an automatic tapping device of lathe, automatic tapping device of lathe includes taper shank, sleeve, guide bolt and round die, the taper shank sets up respectively with the round die telescopic both ends, the sleeve is including nested urceolus and inner tube each other, it has rectangular hole groove to open on the urceolus, guide bolt runs through rectangular hole groove sets up on the inner tube, guide bolt is at rectangular hole inslot relative motion, the taper shank includes the cone of round platform form and sets up the flat mouthful of cone one end, be equipped with the jackscrew on the round die, the length in rectangular hole groove is tapping length.

Preferably, the cone is made of high strength round steel with a diameter of 40 mm.

Preferably, the outer cylinder is a seamless steel pipe with the diameter of 40 mm.

Preferably, the guide bolt is a high-strength bolt of M10 × 30 mm.

Based on the technical scheme, the utility model has the advantages that:

the utility model discloses an automatic tapping device of lathe has very good practicality, when automatic tapping, the potential safety hazard of output when not only can eliminating former processing screw thread, easy operation easily masters moreover, labour saving and time saving, great improvement work efficiency, applicable in the thread machining of multiple specification, be applicable to the processing of screw thread in batches very much.

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the invention without undue limitation to the invention. In the drawings:

FIG. 1 is a schematic side view of an automatic tapping apparatus for a lathe;

FIG. 2 is a schematic side plan view of the automatic tapping apparatus of the lathe;

fig. 3 is a left side view schematically illustrating the automatic tapping apparatus of the lathe.

Detailed Description

The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

The utility model provides an automatic tapping device of lathe mainly cooperates and uses the automatic tapping of lathe, can choose for use the higher steel of mechanical properties and high strength bolt etc. to make. As shown in fig. 1 to 3, a preferred embodiment of the present invention is shown therein.

As shown in fig. 1 and 2, the automatic tapping device for the lathe comprises a taper shank 5, a sleeve 4, a guide bolt 3 and a round die 1, wherein the taper shank 5 and the round die 1 are respectively arranged at two ends of the sleeve 4, the sleeve 4 comprises an outer cylinder and an inner cylinder which are nested with each other, a long-strip hole groove is formed in the outer cylinder, the guide bolt 3 penetrates through the long-strip hole groove and is arranged on the inner cylinder, and the guide bolt 3 moves relatively in the long-strip hole groove to match the lathe to realize automatic tapping. Since the guide bolt 3 is restricted to perform a reciprocating motion in the elongated hole groove, the length of the elongated hole groove is a tapping length.

The taper shank 5 comprises a cone in a circular truncated cone shape and a flat opening arranged at one end of the cone and is used for being fixed on a lathe. As shown in fig. 3, a top thread 2 is arranged on the round die 1 to fix the round die 1, so that an automatic tapping effect is realized.

Preferably, the cone is made of high strength round steel with a diameter of 40mm, and can be machined by a lathe. Preferably, the outer cylinder is a seamless steel pipe with the diameter of 40 mm. Preferably, the guide bolt 3 is a high-strength bolt of M10 × 30 mm.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
