Abstract

The utility model relates to an automatic borer of a lathe tailstock, which is composed of a sleeve and a hexagon bolt. The inner hole of the sleeve is matched with the outer diameter of a tailstock tube through a mall gap, the inner hole of the sleeve is fixed on the outer diameter of the tailstock tube through the hexagon bolt, and then the side wind of the sleeve is fixed on a knife rest of a lathe carriage. Under the precondition that the tailstock and a guide rail mutually slide, a taper shank of a drill bit is installed in a taper hole of the tailstock tube, the automatic driving and reversing of the knife rest and the carriage drives the tailstock for automatic driving and reversing, and therefore the automatic knife driving and reversing of the drill bit is realized. As the automatic borer of the lathe tailstock is used, the drill bit is conveniently clamped and is accurately positioned, the automatic knife driving and reversing of the drill bit is completely realized, the manual feeding of an operator is removed, the labor strength of the operator is reduced, and the working efficiency is increased.

Description

The tail stock automatic hole drilling apparatus

Affiliated technical field

The utility model relates to the manufacture field of machine components, is specially adapted to the mechanical processing process of lathe boring.

Background technology

At ordinary times, when we hole on lathe, usually the taper shank with drill bit is installed in the taper hole of tailstock tube, tailstock is fixed on the lathe guide rail, use the handwheel of hand tailstock rear end then, make the axial advance and retreat of tailstock tube, thereby realize the advance and retreat cutter of drill bit along drill bit, this method is for the operation of producing axis hole, axle sleeve in enormous quantities, and operator's labour intensity is big and efficient is very low.

Summary of the invention

For solving the low difficult problem of manual advance and retreat drilling efficiency, the utility model provides a kind of easy to operate tail stock automatic hole drilling apparatus.

The technical scheme that its technical problem that solves the utility model adopts is: according to the design feature of lathe boring, make a tail stock automatic hole drilling apparatus.Be fixed in earlier on the external diameter of tailstock tube; Be fixed to again on the knife rest of lathe carriage; Under the prerequisite that tailstock and guide rail slide mutually, the taper shank of drill bit is installed in the taper hole of tailstock tube, the automatic advance and retreat of knife rest and supporting plate drive tailstock and advance and retreat automatically, thereby realize the automatic tool advancing and retracting of drill bit.

It is characterized in that: the tail stock automatic hole drilling apparatus is made up of sleeve and hex bolts two parts.The sleeve endoporus of tail stock automatic hole drilling apparatus and the external diameter of tailstock tube adopt little matched in clearance, fix by hex bolts; The flank of sleeve is fixed on the knife rest of lathe carriage.

The beneficial effects of the utility model are:

1) uses the utility model, drill bit convenient mounting and clamping, accurate positioning;

2) knife rest and supporting plate drive tailstock are advanced and retreat automatically, realize the automatic tool advancing and retracting of drill bit fully, removed operator's hand feed, reduced operator's labour intensity, operating efficiency has on average improved about 10 times.

3) making of the present utility model is simple, with low cost, is worthy to be popularized.

Description of drawings

Below in conjunction with accompanying drawing and enforcement the utility model is further specified.

Fig. 1 is an installation diagram of the present utility model.

Fig. 2 is that A of the present utility model is to view.

Sequence number among the figure: 1---hex bolts M10 * 30,2---sleeve, 3---flank.

The specific embodiment

Use the utility model, realize the operating process of automatic drilling:

1) external diameter of the sleeve endoporus of tail stock automatic hole drilling apparatus and tailstock tube adopts little matched in clearance, fixes by hex bolts;

2) again the sleeve flank of tail stock automatic hole drilling apparatus is fixed on the knife rest of lathe carriage;

3) tail stock and guide rail are unclamped;

4) taper shank with drill bit is installed in the taper hole of tailstock tube;

5) the automatic advance and retreat drive tailstock of knife rest and supporting plate is advanced and retreat automatically, thereby realizes the automatic tool advancing and retracting of drill bit.

Claims

1. the tail stock automatic hole drilling apparatus is made up of sleeve and hex bolts two parts, it is characterized in that: the external diameter of sleeve endoporus and tailstock tube adopts matched in clearance, and fastening with hex bolts, and the flank of sleeve is fixed on the knife rest of lathe carriage.
