Abstract
The utility model belongs to the technical field of the machine tool accessory technique and specifically relates to a locking type three -jaw chuck. It includes disk body, jack catch, little bevel gear and big bevel gear, and jack catch and little bevel gear are located the tip and the lateral part of disk body respectively, and big bevel gear is located the inside of disk body, and little bevel gear is connected with big bevel gear meshing, is equipped with clamp plate and awl seat on the jack catch, is equipped with bail and jump ring on the awl seat. Set up clamp plate and awl seat on the jack catch, increase area of contact to set up bail and jump ring on the awl seat, form nail income formula coupling mechanism. During the use, along with the propulsion of jack catch, the clamp plate impels with awl seat is synchronous, forces bail extrusion body, the body was pierce in the sharp -pointed top of bail under the pressure effect surface to pretension under the effect of jump ring, it is even as an organic whole with the body, improved greatly and connected closely degree, prevent effectively that the during operation is not hard up.
Description
Technical field
The utility model relates to machine tool accessories technical field, especially a kind of Anti-loose scroll chuck.
Background technology
Scroll chuck utilizes to be distributed on moving radially of three movable jaws on chuck body, the machine tool accessories of Workpiece clamping and location.Existing scroll chuck structure is simple, and jaw surface is smooth, is plane contact when contacting with body, connects compactness poor, easily loosens during work.
Utility model content
Poor in order to overcome existing scroll chuck connection compactness, the deficiency easily loosened during work, the utility model provides a kind of Anti-loose scroll chuck.
The utility model solves the technical scheme that its technical problem adopts: a kind of Anti-loose scroll chuck, comprise disk body, claw, bevel pinion and bevel gear wheel, claw and bevel pinion lay respectively at end and the sidepiece of disk body, bevel gear wheel is positioned at the inside of disk body, bevel pinion and bevel gear wheel are connected with a joggle, claw is provided with pressing plate and cone seat, and cone seat is provided with bail and jump ring.
According to another embodiment of the present utility model, comprising pressing plate is further circular arc, is connected to the front end of claw 2, and cone seat is evenly distributed on the inwall of pressing plate.
According to another embodiment of the present utility model, comprise bail further and be vertically inserted on cone seat, be slidably connected with cone seat.
According to another embodiment of the present utility model, comprise the afterbody that jump ring is enclosed within bail further, be stuck between cone seat and bail.
The beneficial effects of the utility model are, claw arranges pressing plate and cone seat, enlarge active surface, and arrange bail and jump ring on cone seat, formed and hammer into formula bindiny mechanism.During use, along with the propelling of claw, pressing plate and cone seat synchronously advance, force bail extrude body, the pointed tip of bail thrusts the surface of body under pressure, and under the effect of jump ring pretension, be connected as a single entity with body, substantially increase connection tight ness rating, effectively prevent from loosening during work.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. disk bodies, 2. claw, 3. bevel pinion, 4. bevel gear wheel in figure, 5. bore seat, 6. bail, 7. jump ring, 8. pressing plate.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of Anti-loose scroll chuck, comprise disk body 1, claw 2, bevel pinion 3 and bevel gear wheel 4, claw 2 and bevel pinion 3 lay respectively at end and the sidepiece of disk body 1, bevel gear wheel 4 is positioned at the inside of disk body 1, bevel pinion 3 and bevel gear wheel 4 are connected with a joggle, and claw 2 is provided with pressing plate 8 and cone seat 5, and cone seat 5 is provided with bail 6 and jump ring 7.Pressing plate 8, in circular arc, is connected to the front end of claw 2, and cone seat 5 is evenly distributed on the inwall of pressing plate 8.Bail 6 is vertically inserted on cone seat 5, is slidably connected with cone seat 5.Jump ring 7 is enclosed within the afterbody of bail 6, is stuck between cone seat 5 and bail 6.
Claw 2 arranges pressing plate 8 and cone seat 5, enlarge active surface, and bail 6 and jump ring 7 are set on cone seat 5, formed and hammer into formula bindiny mechanism.During use, along with the propelling of claw 2, pressing plate 8 and cone seat 5 synchronously advance, bail 6 is forced to extrude body, the pointed tip of bail 6 thrusts the surface of body under pressure, and under the effect of jump ring 7 pretension, be connected as a single entity with body, substantially increase connection tight ness rating, effectively prevent from loosening during work.
