Abstract
The utility model discloses a three-jaw chuck structure which comprises a chuck body and clamping jaws. The clamping jaws are arranged on the chuck body. The three-jaw chuck is characterized in that the clamping jaws are further provided with compression parts. Each compression part comprises a pressing plate, an adjusting bolt and a compression bolt. The pressing plates and the clamping jaws are connected through the compression bolts and the adjusting bolts. The three jaw chuck has the advantages of being capable of reducing cost of processing of tools on outer walls of an inner guide barrel and an outer guide barrel and consumption of expenditure of time, enabling quality of products to be more stable, overcoming the shortcomings that when an external embracing tool is adopted to clamp the outer diameter of the guide barrels, micro-defects are generated on surfaces of the workpieces so that quality and service life of the guide barrels are influenced.
Description
Technical field
The utility model relates to a kind of scroll chuck of mechanical field, is specifically related to a kind of scroll chuck for processing refluence cylinder.
Background technology
Process at present particularly outer wall of guide shell, the industry adopts special-purpose frock usually, but from 18 to 24 cun each producers and size be disunity all, external diameter from 471 to 608 each sizes have, therefore when the inside and outside guide shell outer wall of processing, can produce a large amount of frock expense and expenditure of time, product quality is also unstable, when some adopts hem type frock clamping guide shell external diameter, the circumferential pressure that produces, easily produce some microdefects at surface of the work, affect product quality and the service life of guide shell.
Summary of the invention
Consider the problems referred to above of prior art, according to an aspect of the present utility model, a kind of scroll chuck structure is disclosed, comprise disk body of chuck and at least two claws, described claw is arranged on the disk body of chuck, also be provided with compacting part on the described claw, described compacting part comprises pressing plate, adjusts bolt and hold-down bolt, and described pressing plate and claw interfix by hold-down bolt and adjustment bolt.
As preferably, described claw is to the top of pressing plate, and keeps the gap between claw and the pressing plate.
As preferably, described disk body of chuck is circular hollow structure.
As preferably, described claw comprises three, and described three claw structures are identical, and described three claws evenly are arranged on the disk body of chuck by 120 degree angles.
The purpose of this utility model is intended to design a kind of scroll chuck structure more handy, simple in structure.Compared with prior art, one of the beneficial effects of the utility model are: can reduce the inside and outside guide shell outer wall frock expense of processing and expenditure of time, fixedly more stable when guide shell simultaneously, guarantee the crudy of product, cause producing some microdefects at surface of the work in the time of can overcoming employing hem type frock clamping guide shell external diameter, affect the product quality of guide shell and the deficiency in service life.
Description of drawings
Fig. 1 shows according to the structural representation that is the scroll chuck of an embodiment of the present utility model;
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples, but embodiments of the present invention are not limited to this.
Fig. 1 shows according to being the scroll chuck structure structural representation of an embodiment of the present utility model.A kind of scroll chuck structure as shown in Figure 1, comprise disk body of chuck 1 and claw 2, claw 2 tops are provided with compacting part, compacting part is comprised of pressing plate 5, adjustment bolt 3 and hold-down bolt 4, in practical operation, elder generation is according to the size of the cylinder cylindrical that flows backwards on the drawing, regulate pressing plate 5 levels by adjusting bolt 3, tightening hold-down bolt 4 hangs guide shell after plane, limit and chuck plane be adjacent to, adjust again claw 2 and make the slight contact of the claw 2 cylinder cylindricals that flow backwards, then according to drawing requirement with guide shell outer wall completion of processing.The embodiment that the utility model is more preferably be described claw 2 to the top of pressing plate 5, and keep the gap between claw 2 and the pressing plate 5.
" embodiment " who speaks of in this manual, " another embodiment ", " embodiment ", " preferred embodiment " etc., the specific features, structure or the characteristics that refer in conjunction with this embodiment description are included among at least one embodiment of the application's generality description.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in specification.Furthermore, when describing a specific features, structure or characteristics in conjunction with arbitrary embodiment, what advocate is to realize that in conjunction with other embodiment this feature, structure or characteristics also drop in the scope of the present utility model.
