Abstract

The utility model relates to the technical field of machine tool accessories, in particular to a machine tool chuck. The machine tool chuck is provided with a chuck main body which is provided with a small bevel gear and a big bevel gear. A collet is arranged at the upper end of the big bevel gear. An Archimedes spiral line is arranged between the big bevel gear and the collet. The collet is meshed with the Archimedes spiral line through a bolt. The machine tool chuck is simple in structure; and a single-acting screw rod is independently arranged on the collet, accordingly regular rotary workpieces or regular non-rotary workpieces can be conveniently tightly clamped, the chuck is needless to be frequently replaced during work, and working efficiency is improved.

Description

Machine chuck
Technical field
The utility model relates to the machine tool accessories technical field, especially a kind of machine chuck.
Background technology
Chuck is the effect of playing clamping work pieces in the lathe work, because dividing of the well-regulated cylindrical of cylindrical of workpiece and irregular cylindrical, so, on general lathe, also just correspondingly be equipped with self-centering expansion chuck and single action expansion chuck, come respectively the clamping to regular cylindrical and irregular outer circular Curve, simultaneously, in the processing of the workpiece of some eccentric shaft classes and some other workpiece, also to use respectively different chucks, because these situation, so, need at work the requirement according to workpiece situation and technique, change chuck at lathe frequently, thereby reduce production efficiency.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, provide a kind of simple in structure, do not need at work frequent chuck, the machine chuck of increasing work efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of machine chuck, has chuck main body, bevel pinion and bevel gear wheel are installed on the described main body, the bevel gear wheel upper end is provided with chuck, be provided with spiral of Archimedes between bevel gear wheel and chuck, chuck forms meshing relation by bolt and spiral of Archimedes.
Further, described spiral of Archimedes upper end is connected with the single action screw mandrel, and single action screw mandrel head is equipped with the fixed chuck body, and the single action screw mandrel passes the chuck cavity and is connected with the fixed chuck body, and the single action screw mandrel links together by screw thread and chuck.
The beneficial effects of the utility model are: the utility model is simple in structure, and the single action screw mandrel is housed on chuck independently, so can clamp easily rotation class or the non-rotating class workpiece of rule, does not need at work frequent chuck, increases work efficiency.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. main bodys among the figure, 2. bevel pinion, 3. bevel gear wheel, 4. chuck, 5. single action screw mandrel, 6. fixed chuck body, 7. spiral of Archimedes, 8. bolt, 9. chuck cavity.
The specific embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
Machine chuck as shown in Figure 1, have chuck main body 1, bevel pinion 2 and bevel gear wheel 3 are installed on the main body 1, bevel gear wheel 3 upper ends are provided with chuck 4, be provided with spiral of Archimedes 7 between bevel gear wheel 3 and chuck 4, chuck 4 forms meshing relation by bolt 8 and spiral of Archimedes 7; Spiral of Archimedes 7 upper ends are connected with single action screw mandrel 5, and single action screw mandrel 5 heads are equipped with fixed chuck body 6, and single action screw mandrel 5 passes chuck cavity 9 and is connected with fixed chuck body 6, and single action screw mandrel 5 links together by screw thread and chuck 4.
This machine chuck is simple in structure, and single action screw mandrel 5 is housed on chuck 4 independently, so can clamp easily rotation class or the non-rotating class workpiece of rule, does not need at work frequent chuck, increases work efficiency.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection domain of the present utility model.
