Abstract
The utility model provides a novel drilling clamp. The novel drilling clamp comprises a chuck connected with an electric dividing head, wherein the chuck comprises a positioning disk and a claw; the chuck is a post-tensioning externally-braced chuck; the claw and an outer arc surface contacted with the inner diameter of a workpiece form radial positioning reference of the workpiece; the outer end of the claw is provided with an inclined surface forming an angle with the outer arc surface; and the inclined surface is matched with the outer end surface of a chuck body as axial positioning reference of the workpiece. Through the application of the post-tensioning chuck of the novel drilling clamp, a transition disk is used as positioning reference, and the claw is positioned by adopting a 20-degree conical surface as a center, so that axial positioning and radial positioning of the workpiece are realized at the same time during the drilling and clamping process.
Description
Technical field
The utility model relates to field of machining, refers to a kind of novel boring grab especially.
Background technology
When the uniform radial hole of processing annular work piece excircle is, adopt standard chuck clamping workpiece at present, be equipped with the processing of electric dividing head rotation calibration.Because in clamping process, when the chuck claw is opened outward, generally all can only radially position, and axially can not produce active force to workpiece, the workpiece datum level can not guarantee to fit with the claw datum level fully.For example certain circumferential apertures is after the Workpiece boring processing of 15.82mm, and the pitch-row datum level can occur than great fluctuation process, causes the bad generation of product.
The utility model content
The utility model proposes a kind of novel boring grab, realized in the boring clamping process workpiece spindle to time location radially.
The technical solution of the utility model is achieved in that a kind of novel boring grab, comprise the chuck that is connected with electric dividing head, described chuck comprises positioning disk and claw, described chuck is the outer Zhang Kapan of rear pull type, the extrados that described claw contacts with workpiece diameter constitutes the radial location benchmark of workpiece, the outer end of claw is provided with the inclined-plane at an angle to each other with its extrados, and described inclined-plane cooperates with the outer face of chuck body and is the axial location benchmark of workpiece.
As preferably, described chuck is connected with electric dividing head by transition disc.
As preferably, described chuck is the outer Zhang Kapan of three-jaw rear pull type.
As preferably, the angle between described inclined-plane and the horizontal plane is 10 °～30 °.
As preferably, the angle between described inclined-plane and the horizontal plane is 20 °.
Compared with prior art, advantage of the present utility model is: the utilization of rear pull type chuck, transition disc are as the location benchmark, and claw adopts 20 ° of conical surfaces as centralized positioning, realized in the boring clamping process workpiece spindle to time location radially, guarantee that chuck is to the crystallized ability of workpiece.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is the right view of Fig. 1;
Front view when Fig. 3 is chuck of the present utility model assembling workpiece.
Among the figure: 1, electric dividing head; 2, positioning disk; 3, claw; 4, workpiece; 5, inclined-plane.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment: referring to Fig. 1, Fig. 2 and Fig. 3, a kind of novel boring grab, comprise the chuck that is connected with electric dividing head 1, described chuck comprises positioning disk 2 and claw 3, described chuck is the outer Zhang Kapan of rear pull type, extrados that described claw 3 contacts with workpiece 4 internal diameters constitutes the radial location benchmark of workpiece 4, and the outer end of claw 3 is provided with the inclined-plane 5 at an angle to each other with its extrados, and described inclined-plane 5 cooperates with the outer face of chuck body and is the axial location benchmark of workpiece 4.
As preferably, described chuck is connected with electric dividing head 1 by transition disc.
As preferably, described chuck is the outer Zhang Kapan of three-jaw rear pull type.
As preferably, the angle between described inclined-plane 5 and the horizontal plane is 10 °～30 °.
As preferably, the angle between described inclined-plane 5 and the horizontal plane is 20 °.
The chuck that the utility model adopts is the outer Zhang Kapan of rear pull type, positioning disk 2 cooperates transition disc as the axial location benchmark, the chuck claw with 20 ° of inclined-planes 5 as the centering datum levels, outside claw 3, open in the process, because the axial thrust load on the back pull of chuck and 20 ° of inclined-planes 5, workpiece 4 is moved axially, be close to transition disc location datum level, guaranteed that circumferential apertures is apart from 15.82 unanimities.
Shortcomings such as it is inaccurate that the utility model has solved in the boring procedure clamping location, and workpiece 4 datum levels and fixture datum applying are bad have reduced the bad generation of pitch-row in the production process.
Key point of the present utility model and protection point are: the utilization of rear pull type chuck, and cooperate transition disc as the location benchmark, claw 3 adopts 20 ° of conical surfaces as centralized positioning, has realized in the boring clamping process axially location with radially time of workpiece 4.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
