Detailed description of the invention
The utility model embodiment discloses a kind of compound handle of a knife, with problems such as the low and mismachining tolerance of the working (machining) efficiency of the centre bore and end face that solve axial workpiece are large.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-Fig. 3, in a kind of specific embodiment, present embodiments provide a kind of compound handle of a knife, compound handle of a knife can the simultaneously centre drill of installing drill centre bore and the lathe tool of face work.Concrete, one end of compound handle of a knife is the connecting portion other end be fixedly connected with the main shaft of lathe is tool mounting portion.
Wherein connecting portion has centration axis 1 and the flange 2 coaxial with centration axis 1, and wherein the main shaft of centration axis 1 matches with axis hole, makes the axis of centration axis 1 and the axis of main shaft on same straight line.Flange 2 is in flange-type, mainly play a part compound handle of a knife to be connected with main shaft, flange 2 is arranged in one end of the close tool mounting portion of centration axis 1 namely away from one end of main shaft, and flange 2 has the bolt hole of the axis being parallel to centration axis 1, make flange 2 can carry out bolt with main shaft by above-mentioned bolt hole and be connected.Because flange 2 is in template, so intensity is lower, easy flexural deformation, general method thickeies for flange 2, but in order to alleviate the weight of compound handle of a knife entirety, so can arrange gusset 7, gusset 7 is positioned at the side away from main shaft of flange 2, the main body of gusset 7 flange connector 2 and compound handle of a knife, strengthens the intensity of flange 2.In order to be that the connecting portion of the flange-type that flange 2 can be corresponding with on main shaft fits together, so will ensure that centration axis 1 is inserted in the axis hole of main shaft completely, therefore centration axis 1 adds the side place that will be worked into flange 2 man-hour, so for the ease of processing, arrange escape 11 in the end of centration axis 1, this escape 11 is positioned at the outer rim of one end of the close flange 2 of centration axis 1.
Tool mounting portion has the installing hole 3 of centre drill and the erecting bed 4 of lathe tool, wherein lathe tool refers to the lathe tool of axletree class part end face, installing hole 3 is coaxial with centration axis 1, makes installing hole 3 can be coaxial with main shaft, and then ensures that the centre bore that centre drill bores is coaxial with main shaft.There being the first screw hole 5 penetrating into installing hole 3 from the lateral surface of tool mounting portion along the radial arrangement of installing hole 3, after centre drill is installed into installing hole 3, screw namely can be used to clamp centre drill.Wherein erecting bed 4 is arranged on the outer rim of tool mounting portion, and the axis of the table top of erecting bed 4 and installing hole 3 is positioned at same plane, to facilitate installation lathe tool, there is on erecting bed 4 second screw hole 6 of at right angle setting platform 4 simultaneously, when mounting cutter, adopt the second screw hole 6 to carry out lathe tool and fix.It should be emphasized that the concrete shape size of erecting bed 4 herein, should design according to the shape and size of concrete lathe tool the erecting bed 4 matched.In order to lathe tool moving playing surface along erecting bed 4 better can be limited, and alleviate the pressure of the second screw hole 6, a leg-of-mutton stopper slot 8 arranged by erecting bed 4, this stopper slot 8 extends to the end face of compound handle of a knife, namely show that leg-of-mutton stopper slot 8 lacks a trough rim, make more eurypalynous lathe tool can be installed.
During installation, first the centration axis 1 of compound handle of a knife is inserted in the axis hole of machine tool chief axis, then compound handle of a knife is fixedly connected with the main shaft of lathe by connecting portion, finally with screw, centre drill is fixed in installing hole 3 and with another screw, lathe tool is fixed on erecting bed 4.
In order to better install compound handle of a knife fast, at the lateral surface of centration axis 1, the bevel being parallel to the axis of centration axis 1 is set, namely the cross section of centration axis 1 is the imperfect circle with straightway, the cross section of the axis hole of corresponding main shaft matches with the cross section of centration axis 1 also for having the imperfect circle of straightway, namely makes centration axis 1 all match with the axis hole size shape of main shaft all the time.
Some lathe connectors may be threaded connectors, so the screwed hole 9 coaxial with centration axis 1 can be provided with in one end of the close main shaft of compound handle of a knife, compound handle of a knife can be threaded with lathe, but preferably tightening direction is consistent relative to turning to of lathe tool with part to be processed, loosen to prevent the connection between compound tool and lathe.
Based on the compound handle of a knife provided in above-described embodiment, the utility model additionally provides a kind of lathe, and this lathe comprises any one compound handle of a knife in above-described embodiment.The centration axis 1 of compound handle of a knife is inserted in the axis hole of the main shaft of lathe, and the flange 2 of compound handle of a knife is connected with the principal axis bolt of lathe.The compound handle of a knife in above-described embodiment is have employed, so the beneficial effect of this lathe please refer to above-described embodiment due to this lathe.
In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
