Description

The structure of screw Mo

Technical field

The utility model relates to the structure of a kind of screw Mo, mainly is the cutting tool that is used in screw thread.

Background technology

The male screw cutting tool of being habitually practised at present, for example Granted publication number is CN2461688Y " the adjustable screw Mo of improvement ", as shown in Figures 1 and 2, mainly formed by screw Mo tool rest 1 and handle of a knife 11, these handle of a knife 11 systems are provided with a deep hole 111, can cooperate for screw Mo tool rest 1 and pack into, and between deep hole 111 wall thickness, be provided with screwed hole 112, cooperate a bolt 113 to lock and screw Mo tool rest 1 is locked in the deep hole 111.

But above-mentioned structure and embodiment; though can obtain the externally threaded purpose of ream; but because of handle of a knife 11 is closed; there is not the design of iron filings evacuation aperture; so when doing external screw thread processing cutting; regular meeting can't discharge the carrying out of the work of influence smoothly because of iron filings, often will interrupt machine run midway and clear up 1 li iron filings that are mingled with of screw Mo tool rest.

Moreover, because of handle of a knife 11 is closed design,, remove the blade 12 of 1 li of sufficient lubrication screw Mo tool rest so in the processing working angles, also cannot inject cutting agent, and the service life of reducing screw Mo tool rest 1 greatly.

In addition, when desiring the pore size of fine adjustment screw Mo tool rest 1, get earlier bolt 113 to be revolved and move back some distances,, just can do the adjustment of transferring screw Mo tool rest 1 pore size, so adjustment process comparatively bothers screw Mo tool rest 1 can be drawn off from handle of a knife 11; And, will influence whole process operation if bolt 113 gets loose (not tightening) in the ream threaded process.

And because screw Mo tool rest 1 is to separate to make with handle of a knife 11, so after the combination, still have off-centre slightly, both concentricitys are not so accurate just, adjust by rule of thumb, could obtain the concentricity and the ream accurate dimension of standard.

Summary of the invention

The purpose of this utility model is to provide the structure of a kind of screw Mo, reaches more easy use operation, and the use that can the overcome existing structure defective of handle of a knife installing of need arranging in pairs or groups is saved the trouble that loading and unloading are proofreaied and correct, and can develop efficiency greatly.

Another purpose of the present utility model is to provide the structure of a kind of screw Mo, make in the process of machining screw, iron filings can be discharged smoothly, avoid interrupting machine run midway and clear up iron filings in the screw Mo tool rest, simultaneously, can inject cutting agent by chip-removal hole, can be in screw Mo processing working angles, each cutting edge in the sufficient lubrication screw Mo tool rest can prolong service life of screw Mo tool rest greatly.

The purpose of this utility model is to realize like this, the structure of a kind of screw Mo, dig at the endoporus of screw Mo tool rest and to be provided with several mesopores, dig again between each mesopore and establish rectangular opening, the screw chasing sword is embedded solid welding and is positioned rectangular opening, this screw Mo tool rest is cut apart groove one at least in circumference, the circumference of screw Mo tool rest is drilled with equidistant and becomes vertical position, a plurality of hole with groove, centre drill is provided with perforation in the interstitial hole position, the groove relative with this perforation side tabular surface in addition is provided with screwed hole, one long screw is worn by perforation and screw lock enters in the screwed hole, the two side holes that is positioned at the interstitial hole position is drilled with the minor thread hole, each enters described minor thread hole and contacts on the tabular surface of other side of groove by a short screw screw lock, and screw Mo tool rest rear end has been made into integration handle of a knife.

Between screw Mo tool rest and handle of a knife, dig and be shaped on relative chip-removal hole.

By said structure as can be known, screw Mo tool rest and handle of a knife are to be made into integration, so concentricity is comparatively accurately good, can obtain the accurate dimension of ream screw thread, and simpler and easy firm in operation; In addition, the design of chip-removal hole, except can be used as the usefulness of getting rid of the cutting iron filings, more can be by chip-removal hole, inject cutting agent making the processing working angles, the cutting edge in can sufficient lubrication screw Mo tool rest prolongs service life of screw Mo tool rest greatly.

The specific embodiment

Consult Fig. 3 and Fig. 4 A, shown in Fig. 4 B, the utility model mainly is that the endoporus 20 at screw Mo tool rest 2 front ends digs and is provided with less mesopore 21, and dig again by 21 of two mesopores and to be shaped on rectangular opening 22, be embedded the solid welding location for refining external thread cutting sword 23, external screw thread as the ream processing object, the usefulness of chip removal during as ream by each mesopore 21, this screw Mo tool rest 2 is cut apart a groove 24 in circumference, be drilled with equidistant and become vertical position, a plurality of hole 25 with groove at the circumference of screw

Mo tool rest

2,25 ', 25 "; be drilled with perforation 26 again again at 25 centers, interstitial hole position; with this bore a hole 26 relative grooves 24 in addition side tabular surfaces 27 be provided with screwed hole 28 again; long screw S1 is worn and screw lock enters in the screwed hole 28 by perforation 26; be positioned at the two side holes 25 ' of interstitial hole position 25; 25 " be drilled with minor thread hole 251 ' again, 251 ", respectively enter and contact on the tabular surface 27 of groove 24 other sides by a short screw S2 screw lock.

See also shown in Figure 5ly, when desire is adjusted the aperture and dwindled, will lack screw S2 earlier and revolve and move back some distances, again with long screw S1 precession to the desired reduced bore, again each short screw S2 is threaded into to conflict and is positioned at groove 24 and gets final product on the tabular surface 27 of sides in addition; Otherwise, if will do the aperture when enlarging, long screw S1 is revolved a little move back earlier, again each short screw S2 forward screw lock push against on the tabular surface 28 of other side, just can enlarge and adjust extremely desired size of aperture, then long screw S1 is revolved forward and is locked to suitable tightness and gets final product.

In addition, be made into integration handle of a knife 29 in screw Mo tool rest 2 rear ends, and dig at preceding terminal screw

Mo tool rest

2 and 29 on handle of a knife and to be shaped on relative chip-removal hole 291, this chip-removal hole 291 is as the usefulness of getting rid of the cutting iron filings, can allow the cutting iron filings directly exclude (shown in Fig. 4 B arrow), and more can in the processing working angles, inject cutting agent by chip-removal hole 291 by chip-removal hole 291, remove the cutting edge 23 of 2 li of sufficient lubrication cooling screw Mo tool rests, can prolong the service life of screw Mo tool rest 2 greatly.

By said structure and operating instruction as can be known, screw Mo tool rest and handle of a knife are to be made into integration, so concentricity is comparatively accurately good, can obtain the accurate dimension of ream screw thread, and simpler and easy firm in operation; In addition, the design of chip-removal hole, except can be used as the usefulness of getting rid of the cutting iron filings, more can be by chip-removal hole, inject cutting agent making the processing working angles, the cutting edge in can sufficient lubrication screw Mo tool rest prolongs service life of screw Mo tool rest greatly.
