Abstract

The utility model provides a replaceable reverse pulling countersunk knife. The replaceable reverse pulling countersunk knife mainly comprises an eccentric sleeve, a tungsten steel knife handle and a plurality of countersunk screws, wherein, an inserting hole is formed on the eccentric part of the eccentric sleeve in a penetrating manner; the tungsten steel knife handle is inserted in the inserting hole; a plurality of screw holes are formed on the eccentric sleeve on the surface farther from the inserting hole; the countersunk screws are arranged in the screw holes; an inserting section is arranged at one end of the tungsten steel knife handle, inserted in the inserting hole of the eccentric sleeve, and fixedly locked on the tungsten steel knife handle through the countersunk screws, so as to fix the tungsten steel knife handle; and a cutting edge is arranged at the end part of the tungsten steel knife handle in a position facing outside. When the tungsten steel knife handle is damaged, all that is needed to replace a new or tungsten steel knife handles with different uses is to unscrew the countersunk screws.

Description

The replaceable countersunk head cutter that draws

Technical field

The utility model relates to the replaceable countersunk head cutter that draws, mainly be applied to replace the wolfram steel handle of a knife, the cost-effective countersunk head cutter that draws is technical.

Background technology

Tradition is when the counter sink of processing concentric but different pore sizes, and the employed countersunk head cutter that draws please be consulted existing schematic perspective view shown in Figure 1.Mainly be: it is one thin and be the wolfram steel handle of a knife 41 of eccentric state that this draws countersunk head cutter 40 directly to process on end face, and wolfram steel handle of a knife 41 outer ends also process and are provided with cutting edge 42.

Yet, because traditional draw countersunk head cutter 40 and wolfram steel handle of a knife 41, cutting edge 42 all are formed in one, whole is drawn countersunk head cutter 40 all is that the wolfram steel material is made, when in case the situation of fracture or serious wear takes place with cutting edge 42 in wolfram steel handle of a knife 41, whole is drawn countersunk head cutter 40 just must abandon can't to continue again and uses, cause the waste of material that draws countersunk head cutter 40 virtually, simultaneously also cause buying and draw the countersunk head cutter 40 and the cost of rose reamer to increase, form a kind of added burden of processer, for it had both deposited problem and the defective that waits to overcome solution.

Summary of the invention

The utility model people is engaged in manufacturing, the design of Related product at present, accumulation practical experience and gains in depth of comprehension for many years, commonly use the problem and the defective of drawing the countersunk head cutter both to be deposited at tradition, drop into innovation and the spirit that improves, the replaceable countersunk head cutter of being finished that draws energetically.Its goal of the invention is to provide a kind of replaceable countersunk head cutter that draws, with the problem of the waste of material that draws the countersunk head cutter that solves prior art.

The utility model provides a kind of replaceable countersunk head cutter that draws, and it is characterized in that: this replaceable countersunk head cutter that draws mainly comprises eccentric adjusting sleeve, wolfram steel handle of a knife and countersink head screw; This eccentric adjusting sleeve runs through at eccentric part and is provided with one and plugs the hole, and this plugs and plugs this wolfram steel handle of a knife in the hole, and this eccentric adjusting sleeve plugs hole one side far away in distance and is being provided with a plurality of screws, and described a plurality of screw internal locks are established many described countersink head screws; One end of this wolfram steel handle of a knife is provided with the section of plugging, and this section of plugging is inserted in plugging in the hole of this eccentric adjusting sleeve, and is established by described countersink head screw lock and to be fixed on this wolfram steel handle of a knife, to fix this wolfram steel handle of a knife; The end of this wolfram steel handle of a knife is provided with a cutting edge toward the outer side.

In one embodiment, this wolfram steel handle of a knife is provided with a plane in this section of plugging inboard, and the face that is provided with a plurality of screws of this eccentric adjusting sleeve is the plane, and this plane of this plane on this eccentric adjusting sleeve and this wolfram steel handle of a knife of insertion is parallel to each other.

In one embodiment, this cutting edge is to be used to the chamfering cutting edge processing the cutting edge of counter sink or be used to process the chamfering of counter sink.

The useful technique effect of this novel solution is: the replaceable eccentric adjusting sleeve that draws the countersunk head cutter and wolfram steel handle of a knife are for separating replaceable pattern, when the wolfram steel handle of a knife damages, or change when drawing countersunk head cutter and rose reamer, only need unscrew countersink head screw, promptly can replace wolfram steel handle of a knifes new or different purposes, avoid the waste of material of eccentric adjusting sleeve, can effectively reduce cost and price.

The specific embodiment

The technique effect of understanding structure content of the present utility model in depth and can reach for those skilled in the art are easy to is enumerated a specific embodiment now, and detailed introduction of conjunction with figs. is described as follows.

A kind of replaceable countersunk head cutter that draws, please consult solid combination and the perspective exploded view of the utility model embodiment one shown in Fig. 2,3, with the section combination of the utility model embodiment one shown in Fig. 4,5 and the B-B line generalized section of Fig. 4, and the utility model embodiment one shown in Figure 6 is assemblied in the section combination schematic diagram of milling cutter shank.The replaceable countersunk head cutter that draws is mainly formed with 30 common combinations of countersink head screw by eccentric adjusting sleeve 10, wolfram steel handle of a knife 20; Wherein: eccentric adjusting sleeve 10 runs through at eccentric part and is provided with one and plugs hole 11, can be for plugging a wolfram steel handle of a knife 20, eccentric adjusting sleeve 10 plugs hole 11 another sides far away in distance and is provided with a plane 12, is provided with two screws 13 corresponding to plugging 11 places, hole on the plane 12, can establish two countersink head screws 30 for lock;
