Abstract
The utility model discloses a three-jaw chuck. The three-jaw chuck comprises a chuck body, three clamping jaw bases, a wire coiling body, a small bevel gear and a chuck flange, wherein the three clamping jaw bases are located on the front face of the chuck body, and the wire coiling body, the small bevel gear and the chuck flange are located on the back face of the chuck body. The chuck flange is located in the center of the chuck body, the wire coiling body is located at the position, close to the outer side of the circumference, of the back face of the chuck body, the circumferential threads on the front face of the wire coiling body are matched with the threads of the bottom face of the clamping jaw bases, a large bevel gear on the back face of the wire coiling body is matched with the small bevel gear, and the thread pitch of the circumferential threads on the front face of the wire coiling body is 10mm. The three-jaw chuck carries out clamping conveniently, is large in clamping force and high in efficiency, and saves labor and time.
Description
Technical field
The utility model relates to a kind of lathe hold assembly, particularly a kind of chuck.
Background technology
Existing lathe three-claw chuck generally comprises the parts such as chuck body, parcel body, chuck flange, small conical gear, master jaw, and the parcel body all is positioned at the position of the chuck back side near chuck hub, is positioned at the chuck flange inner.During holding workpiece,, by rotating small conical gear, drive the parcel body and rotate, thereby drive master jaw, move radially, workpiece is clamped and unclamps.The chuck of this structure is due to the parcel body near the center of circle, and moment is little, and when with spanner, rotating small conical gear, relatively effort, firm not to piece-holder, easily occurs loosening phenomenon in process, affects the crudy of product; Moreover existing diameter of chuck is generally below 500mm, and the chuck manufacturing cost that surpasses 800mm or 1000mm for diameter is quite expensive, is not easy clamping work pieces during clamping.Secondly, the thread pitch of the parcel body on market generally is 6mm or 7mm, and pitch is little, and chucking power is little, uses in the spanner rotation process and relatively requires great effort, and clamps efficiency low.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of scroll chuck, can be laborsaving to reach, clamping purpose firmly.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of scroll chuck, comprise chuck body, be positioned at three master jaws in described chuck body front, and the parcel body, small conical gear and the chuck flange that are positioned at the described chuck body back side, described chuck flange is positioned at the center of described chuck body, described parcel body is positioned at the position of the described chuck body back side near periphery, the circumferential thread in described parcel body front and the screw thread of described master jaw bottom surface match, large conical gear and the described small conical gear at the described parcel body back side match, and the pitch of the circumferential thread in described parcel body front is 10mm.
Preferably, be provided with pressing plate bottom described parcel body.
Preferably, described three master jaws are uniformly distributed on described chuck body.
Preferably, described small conical gear has three, and is spaced apart with described master jaw.
Preferably, described master jaw is provided with claw.
Preferably, the back side of described chuck body is distributed with reinforcement.
Pass through technique scheme, the parcel body of the scroll chuck that the utility model provides is positioned at the position of the chuck body back side near periphery, moment is large, the pitch of the circumferential thread in parcel body front is large, and chucking power is large, when rotating small conical gear, more laborsaving, be easy to a piece-holder firm, saved significantly the time of Workpiece clamping, improved and clamped efficiency.
Description of drawings
, in order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described.
Fig. 1 is the generalized section of the disclosed a kind of scroll chuck of the utility model embodiment;
Fig. 2 is the top view of the disclosed scroll chuck of the utility model embodiment;
Fig. 3 is the upward view of the disclosed scroll chuck of the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The utility model provides a kind of scroll chuck, structural representation as shown in Figure 1, and this scroll chuck clamping is firm, and efficiency is high, and is laborsaving.
Scroll chuck as shown in Figure 1, comprise chuck body 1, be positioned at three master jaws 2 (as shown in Figure 2) in chuck body 1 front, and the parcel body 3, small conical gear 4 and the chuck flange 5 that are positioned at chuck body 1 back side, chuck flange 5 is positioned at the center of chuck body 1, parcel body 3 is positioned at the position of chuck body 1 back side near periphery, the screw thread of the circumferential thread in parcel body 3 fronts and master jaw 2 bottom surfaces matches, large conical gear and the small conical gear 4 at parcel body 3 back sides match, and the pitch of the circumferential thread in described parcel body front is 10mm.
Three master jaws 2 of the present embodiment are uniformly distributed on chuck body 1, and master jaw 2 is provided with claw 7, are used for workpiece is clamped, and as shown in fig. 1, claw 7 also can oppositely be placed, and according to the size of different workpiece, selects; Small conical gear 4 has three, spaced apart with master jaw 2, as shown in Figure 3, during holding workpiece, spanner is inserted in the centre bore of small conical gear 4, rotate each small conical gear 4 and can make parcel body 3 rotate, and then drive the movement of master jaw 2, three small conical gears 4 are set can play balanced action, avoided the stressed of part.
The parcel body of the scroll chuck that the utility model provides is positioned at the position of the chuck body back side near periphery, moment is large, be fit to diameter and surpass 8O0mm or the above chuck of 10O0mm, and the thread pitch of parcel body is larger, and chucking power is large, when rotating small conical gear, more laborsaving, be easy to a piece-holder firm, saved significantly the time of Workpiece clamping, improved and clamped efficiency.
, to the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
