Description
Technical field
The utility model relates to the centring means in the cutlery manufacturing procedure, specifically is meant to be convenient to change the top of withstanding part.
Background technology
Cutlery is the instrument that is used for carrying out cut, mainly refers to lathe tool, reamer; Planing tool, drill bits etc. mainly contain two types from the material differentiation: carbide alloy, quenching steel; Common cutlery all is that carbide alloy is whole as cutlery; Advantage is to use the time long, and shortcoming is that cost is too high, and carbide alloy can not utilize fully; Also having a kind of is by the essential part of quenching steel as cutlery, and by the blade of carbide alloy as cutlery, advantage is that cost is low, and shortcoming is to use the life-span short, and anti-wear performance is poor, and processing technology is complicated, and success rate is lower.The manufacturing process of cutlery mainly contains: select materials, blanking, preliminary working, fine finishining, finished product cleaning, detection, packing etc.Wherein preliminary working and fine finishining comprise car, mill, technology such as boring, brill, mill.Because the size of cutlery is less usually, and process belongs to fine finishining, needs its error amount less; That uses is top with after cutlery contacts, and the top hardness of needs adopts extraordinary carbide alloy as top greater than the hardness of cutlery usually usually; But top is running stores, consumable accessory, and also the cost of extraordinary carbide alloy is higher than common iron far away; Therefore, top use cost is high always.
The utility model content
The purpose of the utility model is to provide a kind of the top of withstanding part of being convenient to change, and under the situation that does not influence top use, reduces the waste of extraordinary carbide alloy, reduces top use cost.
The purpose of the utility model realizes through following technical proposals:
Be convenient to change the top of withstanding part; Comprise grip shank, be provided with the feed handle at an end of said grip shank, the feed handle is cylindric; And it is coaxial with grip shank; An end face of grip shank is connected with the feed handle, and the other end of feed handle is connected with the addendum cone of taper type, said addendum cone be provided with addendum cone on disc be connected top.The utility model comprises four parts that connect successively: grip shank, feed handle, addendum cone and top, grip shank are used for being connected with lathe, make himself stable; The feed handle is used for feed, and the cutlery clamping part of lathe can be near the feed handle, so that accomplish the processing to workpiece end; Addendum cone partly plays the effect that reduces to stop, top tip is connected with workpiece, workpiece is played the effect of support, top folder; Grip shank, feed handle, addendum cone and top axis on same straight line, help accurately machined to the heart, under the situation of top damage; Can change top, so, need not the extraordinary carbide alloy making of whole top whole employings; Only need the easily worn part replacing can be kept using, reduced use cost.
Said top disc is provided with a card post, and the last disc of said addendum cone is recessed to form the hole clipping that is complementary with said card post downwards, and the axis of said card post passes top basic circle center and is positioned at same straight line with the axis of addendum cone.Further say; In order to increase top and connectivity robustness addendum cone; The upper surface that is employed in addendum cone is recessed to form hole clipping downwards, and the card cylindricality formula that is complementary with hole clipping is set on the top basic circle, has avoided the relative slip possibility between top and the addendum cone; Make top coaxially again, guaranteed that chucking power is passed to the axis of workpiece with addendum cone.
Described grip shank is frustum, has the end disc of two different-diameters, and the end disc that wherein diameter is big is connected with an end face of feed handle, and grip shank is coaxial with the feed handle.
Described grip shank, feed handle and addendum cone is structure as a whole and processed by the quenching steel, said toply process by carbide alloy, said top fixing through welding with addendum cone.Say that further grip shank, feed handle and addendum cone are structure as a whole, not only be convenient to processing; And its alignment is higher, has overcome eccentric problem, and is processed by the quenching steel; When guaranteeing its intensity, have good toughness again, have only top employing carbide alloy to process; Not only reduce the use amount of carbide alloy, and be convenient to top replacing, reduced top use cost.
The utility model compared with prior art has following advantage and beneficial effect:
1 the utility model is convenient to change the top of withstanding part, and grip shank, feed handle, addendum cone and top axis help accurately machined to the heart on same straight line; Under the situation of top damage; Can change top, so, need not the extraordinary carbide alloy making of whole top whole employings; Only need the easily worn part replacing can be kept using, reduced use cost;
2 the utility model are convenient to change the top of withstanding part; The upper surface that is employed in addendum cone is recessed to form hole clipping downwards; And the card cylindricality formula that is complementary with hole clipping is set on the top basic circle; Avoided the relative slip possibility between top and the addendum cone, made top coaxially again, guaranteed that chucking power is passed to the axis of workpiece with addendum cone;
3 the utility model are convenient to change the top of withstanding part, hold handle, feed handle and addendum cone and are structure as a whole, and not only are convenient to processing; And its alignment is higher, has overcome eccentric problem, and is processed by the quenching steel; When guaranteeing its intensity, have good toughness again, have only top employing carbide alloy to process; Not only reduce the use amount of carbide alloy, and be convenient to top replacing, reduced top use cost;
4 the utility model are convenient to change the top of withstanding part, and are simple in structure, easy to make, can prolonged and repeatedly use, economical and practical.
