Abstract
The patent discloses a three -jaw chuck of area protection nail in the clamping device field is including the chuck body, movable jaw, the movable jaw have threely and the circumference equipartition on the chuck body, the movable jaw is close to the one end at chuck body center is equipped with a plurality of blind holes, the blind hole is followed the direction of radius of the chuck body arranges, still including fixing protection nail in the blind hole, the afterbody of protection nail in the stretching into the blind hole hemispherical head outer with being located the blind hole. Cushion between movable jaw and work piece through protection nail, make the movable jaw body direct with the work piece contact, provide the protection to the movable jaw, make movable jaw and work piece can not prolong the life of movable jaw to causing the damage each other.
Description
Technical field
The utility model relates to clamping device field, particularly a kind of scroll chuck with protection nail.
Background technology
At present, in industrial production, people use lathe to process various workpiece usually, process divides two kinds usually, one be cutter is fixed and workpiece around tool motion to complete processing, another kind be workpiece fixed cutting tool around workpiece motion s to complete processing.No matter be that any processing mode all needs to grip in cutter and workpiece, clamping device conventional on lathe is scroll chuck.
In prior art, scroll chuck is made up of chuck body, movable jaw and claw driving mechanism.On scroll chuck below three claw targeting parts, screw thread is had to be meshed with the flat thread at the dish-shaped bevel gear back side, when rotating cone pinion with spanner by four square holes, dish-shaped pinion rotation, the flat thread at the back side drives three claws close or exit to center simultaneously.There are the following problems for scroll chuck of the prior art: due to movable jaw entirety, to be made of metal its coefficient of friction low, to live to need to provide larger clamping force by workpiece firm grip, under larger clamping force effect, movable jaw is easy to cause damage to surface of the work.And in Long-Time Service, due to the contact of movable jaw front end and gripped object, the wearing and tearing to movable jaw front end can be caused, cause movable jaw cannot clamp workpiece securely, the movable jaw damaged cannot continue to use, and makes movable jaw minimizing in service life.
Utility model content
The utility model is intended to provide a kind of scroll chuck protecting movable jaw front end, to increase the service life of movable jaw.
For achieving the above object, basic technology scheme of the present utility model is as follows: the scroll chuck of band protection nail, comprises chuck body, movable jaw; Described movable jaw has three and circumference is distributed on chuck body; Described movable jaw is provided with some blind holes near the one end at described chuck body center, and described blind hole is arranged along the radial direction of described chuck body; Also comprise the protection nail be fixed in described blind hole, described protection nail comprises the afterbody stretched in blind hole and the hemispherical head be positioned at outside blind hole be made into integration with afterbody.
Principle and the advantage of this programme are: by arranging blind hole on movable jaw, protection nail is set in blind hole, drive protection nail by Workpiece clamping by movable jaw during scroll chuck work, cushioned by protection nail between movable jaw and workpiece, movable jaw body does not directly contact with workpiece, and protection nail provides protection for movable jaw, follows closely if the damage of Long-Time Service rear protecting nail only need change protection, movable jaw body can not produce wearing and tearing, makes the longer service life of movable jaw.
Preferred version one, based on the one of scheme improve, described protection is followed closely and is made up of rubber.The coefficient of friction of rubber is larger than metal, and the frictional force applying rubber during onesize clamping force is larger than metal, arranges like this and makes protection nail have excellent non-skid property, enable scroll chuck more firmly clamping work pieces.
Preferred version two, preferably the one of is improved, and the afterbody circumference of described protection nail extends and forms banking stop.Such setting makes protection nail firmly be fixed in blind hole, can not be taken advantage of a situation take out of and lose when dismantling workpiece.
Preferred version three, preferably the one of two is improved, and described movable jaw is stepped away from the side at described chuck body center.Such setting makes scroll chuck not only can the outer surface of holding workpiece, and can also clamp the inner surface of tubular member, the scope of application is more extensive.

Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the connection diagram that in the utility model embodiment, movable jaw is followed closely with protection;
Fig. 3 is the structural representation protecting nail in the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: chuck body 1, movable jaw 2, blind hole 3, protection nail 4, banking stop 5.
Embodiment is substantially as shown in accompanying drawing 1, Fig. 2: the scroll chuck of band protection nail 4, comprises chuck body 1, movable jaw 2; Described movable jaw 2 has three and circumference is distributed on chuck body 1.Described movable jaw 2 is provided with some blind holes 3 near the one end at described chuck body 1 center, and described blind hole 3 is arranged along the radial direction of described chuck body 1.Also comprise the protection nail 4 being fixed on the rubber in described blind hole 3 and making, described protection nail 4 comprises the afterbody stretched in blind hole 3 and the hemispherical head be positioned at outside blind hole 3 be made into integration with afterbody.Described movable jaw 2 is stepped away from the side at described chuck body 1 center.
As shown in Figure 3, the afterbody circumference of described protection nail 4 extends and forms banking stop 5.The diameter that the diameter of described banking stop 5 is greater than described blind hole 3 is less than the diameter of described protection nail 4 head.
In the present embodiment, by arranging blind hole 3 on movable jaw 2, protection nail 4 is set in blind hole 3, pass through movable jaw 2 during scroll chuck work by Workpiece clamping, cushion by protecting nail 4 between movable jaw 2 and workpiece, movable jaw 2 body does not directly contact with workpiece, protection nail 4 provides protection for movable jaw 2, if Long-Time Service rear protecting nail 4 damages only need change protection nail 4, movable jaw 2 body can not produce wearing and tearing, makes the longer service life of movable jaw 2.The coefficient of friction of rubber is larger than metal, and the frictional force applying rubber during onesize clamping force is larger than metal, and the protection nail 4 that rubber is made has excellent non-skid property, enables scroll chuck more firmly clamping work pieces.The afterbody circumference of protection nail 4 extends and forms banking stop 5, makes protection follow closely 4 can firmly be fixed in blind hole 3 by banking stop 5, can not be taken advantage of a situation take out of and lose when dismantling workpiece.Be set to stepped by described movable jaw 2 away from the side at described chuck body 1 center, make scroll chuck not only can the outer surface of holding workpiece, can also clamp the inner surface of tubular member, the scope of application be more extensive.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and/or characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
