Description

Chuck
Technical field
This utility model belongs to field of mechanical technique, relates to a kind of chuck.
Background technology
Chuck is typically driven three parts to form by chuck body, movable jaw and claw, is the moving radially, Workpiece clamping and the machine tool accessories of location of the movable jaw that is distributed on chuck body of a kind of utilization.There are through hole in chuck body central authorities, in order to by workpiece, and there are cylinder or short taper profile structure in the back of chuck body, is connected with machine tool chief axis end directly or by ring flange.Chuck is typically mounted on lathe, cylindrical grinder and internal grinder use, it is possible to coordinate with various indexing means, for milling machine and drilling machine.
At present, in Machining of Shaft-type Parts field, lathe is to use process equipment the most frequently, add man-hour, axial workpiece is typically clamped by chuck and is positioned on lathe spindle, along with lathe spindle drives axial workpiece high speed rotating, add the cutter on upper tool post and axial workpiece is carried out cutting movement simultaneously.For longaxones parts, add and easily rock man-hour, affect machining accuracy;If the end of axial workpiece has step, and when size between the two differs bigger, it is impossible to chuck, it is clamped.
Summary of the invention
The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that a kind of reasonable in design, be suitable to axial workpiece location with clamping chuck.
The purpose of this utility model can be realized by following technical proposal:
This chuck, the first claw of being uniformly located on chuck body including chuck body, at least two and for driving the first claw along the first driving structure of chuck body radial motion, it is characterized in that, the second claw that at least two is uniformly arranged it is additionally provided with and for driving the second claw along the second driving structure of chuck body radial motion on described chuck body, the clamping radius of described second claw is more than the clamping radius of the first claw, and the axial length of described second claw is more than the axial length of the first claw.
In above-mentioned chuck, the first described driving structure includes its end face being located in chuck body and the first bevel gear wheel of the first claw engagement and is located at first bevel pinion engaged with the first bevel gear wheel of chuck body sidepiece.
In above-mentioned chuck, the second described driving structure includes its end face being located in chuck body and the second largest bevel gear of the second claw engagement and is located at second bevel pinion engaged with second largest bevel gear of chuck body sidepiece, described second largest bevel gear is positioned at the outside of above-mentioned first bevel gear wheel, and the second described bevel pinion and the first bevel pinion are positioned at the not homonymy of chuck body.
In above-mentioned chuck, the first described claw is 2-3;The second described claw is 2-3, and the first described claw and the second claw are spaced apart.
In above-mentioned chuck, the first described claw is 2.
In above-mentioned chuck, the second described claw is 2.
This chuck is mainly used in clamping end and has stepped axial workpiece, and the first claw is for clamping the path of axial workpiece, and the second claw is for clamping the big warp of axial workpiece.During clamping, axial workpiece is put between the first claw, regulate the first bevel pinion, make the first claw be clamped by the path of part, then regulate the second bevel pinion, make big through clamping by part of the second claw, reach the purpose of part stable holding.
Compared with prior art, this chuck has the advantage that by spaced first claw and the second claw, the axial workpiece can with ladder clamps, and part stability in the course of processing can be effectively ensured, thus improve the machining accuracy of part;The reasonable in design of this chuck, owing to the first bevel pinion and the second bevel pinion are positioned at the not homonymy of chuck body, easy to adjust, applied widely.
Accompanying drawing explanation
Fig. 1 is the top view of a kind of preferred embodiment that this utility model provides.
Fig. 2 is sectional view at A-A in Fig. 1 that this utility model provides.
In figure, 1, chuck body;2, the first claw;3, the second claw;4, the first bevel gear wheel;5, the first bevel pinion;6, second largest bevel gear;7, the second bevel pinion.
Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is further described, but this utility model is not limited to these embodiments.
Chuck as shown in Figure 1, the first claw 2 of being uniformly located on chuck body 1 including chuck body 1, at least two and for driving the first claw 2 along the first driving structure of chuck body 1 radial motion, as shown in Figure 1, the second claw 3 that at least two is uniformly arranged it is additionally provided with and for driving the second claw 3 along the second driving structure of chuck body 1 radial motion on chuck body 1, the clamping radius of the second claw 3 is more than the clamping radius of the first claw 2, and the axial length of the second claw 3 is more than the axial length of the first claw 2.
As in figure 2 it is shown, first drives structure include its end face being located in chuck body 1 and the first bevel gear wheel 4 of the first claw 2 engagement and be located at first bevel pinion 5 engaged with the first bevel gear wheel 4 of chuck body 1 sidepiece.
As shown in Figure 2, second drives structure include its end face being located in chuck body 1 and the second largest bevel gear 6 of the second claw 3 engagement and be located at second bevel pinion 7 engaged with second largest bevel gear 6 of chuck body 1 sidepiece, second largest bevel gear 6 is positioned at the outside of above-mentioned first bevel gear wheel 4, and the second bevel pinion 7 and the first bevel pinion 5 are positioned at the not homonymy of chuck body 1.
In use, can arrange the first claw 2 and quantity of the second claw 3 according to practical situation, in order to cost-effective, the first claw 2 can be set to 2-3, the second claw 3 is set to 2-3, the first claw 2 is spaced apart with the second claw 3.
