Abstract
The utility model belongs to the field of the machining of valves of internal combustion engines and particularly relates to a hard-alloy clamping chuck of a numerical-control lathe. The hard-alloy clamping chuck comprises a clamping chuck sleeve and a clamping chuck, wherein the clamping chuck and the clamping chuck sleeve are in sleeved connection; the clamping chuck comprises hard alloy, and the hard alloy is arranged on clamping faces of the clamping chuck through in a welding and embedding manner. The hard-alloy clamping chuck of the numerical-control lathe, adopting the technical scheme of the utility model, has the advantages of high machining accuracy, high production efficiency, long service life and low manufacturing cost.
Description
Technical field
The utility model belongs to the field of machining of engine valve, is specifically related to a kind of numerically controlled lathe carbide alloy chuck.
Background technology
Collet is the machine tool accessories that utilizes the strain of jaw to make workpiece or cutter centering and clamp.Collet usually is equipped with in the hole of machine tool chief axis and uses.Have vertically the elongated slot of 3 or 4 deciles with the head of male cone (strobilus masculinus), the jaw that formation can centripetal contraction.Interior hole shape cuts shape according to clipped object and can be made into circle, square or hexagon.In the valve process, need accurately locate its bar section, guarantee the precision of its processing, so collet is also the preferably positioning fixture in the valve process.
In prior art, to valve outer rim and conical surface chuck, adopt spring steel to add the high frequency quenching, for the ease of changing, used the combination of outer chuck and interior chuck, there is following problem in this combination clamping device in to the valve process: 1, due to the assembling between the assembling between inside and outside chuck and outer chuck and tapered sleeve, itself there is the build-up tolerance accumulation, interior chuck is more easy to wear in addition, use the shorter time, when turning valve outer rim and the conical surface, the vibrations of valve stem and the amplitude of beating will become large, make machining accuracy reduce gradually along with the increase of the duration of processing, 2, because interior chuck is easy to wear, service life is shorter, and the replacing frequency of chuck increases, thereby causes production efficiency to reduce, and has also increased manufacturing cost simultaneously.
The utility model content
The technical problems to be solved in the utility model is to provide that a kind of machining accuracy is high, production efficiency is high, the numerically controlled lathe carbide alloy chuck of long service life and low cost of manufacture.
In order to solve the problems of the technologies described above, the utility model provides a kind of numerically controlled lathe carbide alloy chuck, includes chuck cover, chuck, described chuck and the socket of described chuck cover, wherein, described chuck comprises carbide alloy, and described carbide alloy welding-on is in the clamping face of described chuck.
Adopt the numerically controlled lathe carbide alloy chuck of technique scheme to there is following advantage: 1,, owing to adopting single chuck directly to coordinate with tapered sleeve, to reduce the repeatedly error of assembling, improved processing and the precision of product; 2, because chuck has carbide alloy at chuck easily-worn position welding-on, extended the service life of chuck, reduced the replacing frequency of chuck, thereby enhanced productivity and reduced manufacturing cost.
As preferred version, consider the convenient processing valve retainer below conical surface and dish angle, the end of described chuck is provided with fan-shaped projection.
The accompanying drawing explanation
Fig. 1 is the disassemblying structure schematic diagram of the utility model embodiment numerically controlled lathe carbide alloy chuck;
Fig. 2 is the structural representation of the clamp position of the utility model embodiment numerically controlled lathe carbide alloy chuck.
Wherein: chuck cover 1; Chuck 2; Fan-shaped protruding 21; Carbide alloy 22; Valve stem 3.
The specific embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
As depicted in figs. 1 and 2, the utility model provides a kind of numerically controlled lathe carbide alloy chuck, a kind of numerically controlled lathe carbide alloy chuck, include chuck cover 1, chuck 2, chuck 2 and 1 socket of chuck cover, wherein, chuck 2 comprises carbide alloy 22, the position that carbide alloy 22 welding-ons are easy to wear in chuck 2, in addition, consider the validity of clamping, chuck 2 easily-worn positions are that chuck 2 is for adding the clamping face of holding valve stem 3, consider the convenient processing valve retainer below conical surface and dish angle, the end of chuck 2 is provided with fan-shaped protruding 21.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
1. a numerically controlled lathe carbide alloy chuck, include chuck cover, chuck, described chuck and the socket of described chuck cover, and it is characterized in that: described chuck comprises carbide alloy, described carbide alloy welding-on is in the clamping face of described chuck.
