Description
Technical field
The utility model relates to frock clamp field, particularly a kind of chuck.
Background technology
Chuck lathe is used for the mechanical device of clamping work pieces.Utilize and be distributed on moving radially of movable jaw on chuck body, the machine tool accessories of Workpiece clamping and location.Chuck is generally made up of chuck body, movable jaw and claw driving mechanism 3 part.Chuck body diameter is minimum is 65 millimeters, maximumly reaches 1500 millimeters, and there are through hole in central authorities, so that by workpiece or bar; There is cylindrical or short taper profile structure at back, directly or be connected by ring flange and machine tool chief axis end.Chuck is usually arranged on lathe, cylindrical grinder and internal grinder and uses, and also can coordinate with various indexing means, for milling machine and drilling machine.
Utility model content
It is simply exquisite that technical problem to be solved in the utility model is to provide a kind of structure, uses easy to operate, and disk body diameter is 1500 millimeters, is applicable to the chuck stepping up various workpiece, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of chuck, by disk body, claw, shaggy tooth, bevel gear wheel, bevel pinion, wrench insertion hole, helicla flute and pawl groove composition, disk body is designed to discoid, card is designed with three pawl grooves of trisection, claw is embedded in pawl groove, the inside of disk body is provided with bevel gear wheel, the surface design of bevel gear wheel has helicla flute, the bottom design of claw has shaggy tooth, shaggy tooth is engaged in spiral fluted groove, the side of disk body is provided with wrench insertion hole, wrench insertion hole is provided with bevel pinion, bevel gear wheel is engaged mutually with bevel pinion.
Preferably, described claw is provided with rubber sheet gasket.
Preferably, described spiral fluted cross section is circular.
Preferably, described shaggy tooth, is made up of tooth, movable axis and ballpoint, and ballpoint is arranged on the tip position of tooth by movable axis, and ballpoint is embedded in helicla flute.
Preferably, described spiral fluted inwall scribbles polytetrafluoroethylene (PTFE).
The beneficial effect of above technical scheme is adopted to be: claw is provided with rubber sheet gasket, such design exerts a force larger when chuck adds clamping of workpieces, can play the function that buffer protection workpiece is injury-free; Spiral fluted cross section is circular, shaggy tooth is made up of tooth, movable axis and ballpoint, ballpoint is arranged on the tip position of tooth by movable axis, ballpoint is embedded in helicla flute, these two is supporting invention design, ballpoint is installed at the tip of shaggy tooth and is embedded in supporting volume round screw thread groove, such design can reduce the friction that shaggy tooth produces in sliding process in helicla flute greatly, claw is moved more laborsaving; Scribble polytetrafluoroethylene (PTFE) in helicla flute, such design reduces spiral fluted friction, such that shaggy tooth is more easy to slide in helicla flute, reduces the damage of sliding and bringing apparatus.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of shaggy tooth shown in Fig. 1.
Wherein, 1---disk body, 2---claw, 3---shaggy tooth, 4---bevel gear wheel, 5---bevel pinion, 6---wrench insertion hole, 7---helicla flute, 8---pawl groove, 9---tooth, 10---movable axis, 11---ballpoint.
Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 and Fig. 2 shows the detailed description of the invention of a kind of chuck of the utility model: a kind of chuck, by disk body 1, claw 2, shaggy tooth 3, bevel gear wheel 4, bevel pinion 5, wrench insertion hole 6, helicla flute 7 and pawl groove 8 form, disk body 1 is designed to discoid, card is designed with three pawl grooves 8 of trisection, claw 2 is embedded in pawl groove, claw 2 is provided with rubber sheet gasket, such design exerts a force larger when chuck adds clamping of workpieces, the function that buffer protection workpiece is injury-free can be played, the inside of disk body 1 is provided with bevel gear wheel 4, the surface design of bevel gear wheel 4 has helicla flute 7, the cross section of helicla flute 7 is circular, shaggy tooth 3 is by tooth 9, movable axis 10 and ballpoint 11 form, ballpoint 11 is arranged on the tip position of tooth 9 by movable axis, ballpoint 11 is embedded in helicla flute 7, these two is supporting invention design, ballpoint 11 is installed at the tip of shaggy tooth 3 and is embedded in supporting volume round screw thread groove 7, such design can reduce the friction that shaggy tooth 3 produces in sliding process in helicla flute 7 greatly, claw 2 is moved more laborsaving, polytetrafluoroethylene (PTFE) is scribbled in helicla flute 7, such design reduces the friction of helicla flute 7, make the more easy slip in helicla flute 7 of shaggy tooth 3, reduce the damage of sliding and apparatus being brought, the bottom design of claw 2 has shaggy tooth 3, shaggy tooth 3 is engaged in the groove of helicla flute 7, the side of disk body 1 is provided with wrench insertion hole 7, wrench insertion hole 7 is provided with bevel pinion 5, bevel gear wheel 4 is engaged mutually with bevel pinion 5.
Shaggy tooth 3 shown in composition graphs 2, be made up of tooth 9, movable axis 10 and ballpoint 11, ballpoint 11 is arranged on the tip position of tooth 9 by movable axis, ballpoint 11 is embedded in helicla flute 7, for the supporting invention design of helicla flute 7, ballpoint 11 is installed at the tip of shaggy tooth 3 and is embedded in supporting volume round screw thread groove 7, such design can reduce the friction that shaggy tooth 3 produces in sliding process in helicla flute 7 greatly, claw 2 is moved more laborsaving.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
