Abstract
The utility model relates to a universal clamping jaw base. The clamping jaw base is provided with an insertion end for being plugged with a chuck. The end face of one end of the clamping jaw base, which is opposite to the insertion end, is provided with a dovetail slot for being plugged with a clamping jaw. The clamping jaw base is also provided with a screw mounting hole that is communicated with the end face of the insertion end and the bottom face of the dovetail slot and that is provided with a thread section. A stop screw for tightly jacking the clamping jaw is screwed in the screw mounting hole. As the clamping jaw base disclosed by the utility model is provided with the stop screw for tightly jacking the jaw, after the frequent direction change of the clamping jaw on the clamping jaw base causes abrasion of the dovetail slot, effective fastening can be achieved simply by screwing the stop screw to tightly jack the clamping jaw on the clamping jaw base, and the problem that the clamping claw cannot be effectively fixed by the screw after the clamping jaw base is abraded in the prior art is solved.
Description
Technical field
The utility model relates to a kind of anchor clamps, is specifically related to a kind of claw pedestal.
Background technology
The replaceable claw of engine lathe use at present comprises claw pedestal and claw, and the claw pedestal generally has the insertion end that is used for the chuck grafting; The end face of a relative end with insertion end is provided with the dovetail groove of grafting claw on this claw pedestal; Claw is plugged in the dovetail groove on the claw pedestal, and passes claw through screw claw is screwed onto on the claw pedestal, when the needs claw commutates; Need screw be got loose, again with the slip away dovetail groove of claw pedestal of claw.The replaceable claw of this structure, after the frequent switching-over of claw, dovetail groove can wear and tear gradually, causes passing the screw of claw, effective stationary jaw, thus cause claw to become flexible.
Summary of the invention
The purpose of the utility model is to provide a kind of general claw pedestal, to solve in the prior art after the dovetail groove of claw pedestal weares and teares the effectively problem of stationary jaw of screw.
In order to address the above problem; A kind of general claw pedestal of the utility model; This claw pedestal has the insertion end that is used for the chuck grafting; The end face of a relative end with said insertion end is provided with the dovetail groove of the claw that is used to peg graft on this claw pedestal, also is provided with the screw mounting hole of the section of being threaded that is communicated with insertion end end face and dovetail groove bottom surface on this claw pedestal, is installed with the backing-up screw that is used to hold out against claw in this screw mounting hole.
Said screw mounting hole comprises that also one holds the counterbore section of said backing-up screw caudal peduncle.
On said claw pedestal, also be provided with and be used to prevent that claw from deviating from the locking mechanism of this claw pedestal.
Described locking mechanism comprises spring and the trip that cooperates with this spring roof pressure; The below, bottom that is positioned at said dovetail groove on this claw pedestal is provided with the chamber that holds spring and trip; Said spring is arranged at the bottom of chamber and the dop of said trip is ejected the bottom land of dovetail groove, and said trip is provided with the operating grip that the trip head is pushed away said dovetail groove bottom to the insertion end direction.
Said dovetail groove is the dovetail groove of single interface, when the interface of this dovetail groove is located at this claw pedestal and is positioned on the adaptive chuck towards an end of chuck hub.
The utility model is provided for holding out against the backing-up screw of claw on the claw pedestal; When claw after frequent switching-over causes the dovetail groove wearing and tearing on the claw pedestal; Only need screw backing-up screw and claw is held out against on the claw pedestal, can realize effectively fixingly, solve in the prior art after the claw pedestal weares and teares the effectively problem of stationary jaw of screw.

The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done detailed description:
A kind of embodiment of general claw pedestal; Shown in Fig. 1 ~ 6, this claw pedestal 1 has the insertion end that is used for the chuck grafting, and this insertion end has the insertion groove 9 that is used for the chuck grafting; And be provided with on the end face of this end be used for chuck on the rectangular thread 7 of planar rectangular threaded engagement; This threaded engagement can make claw pedestal 1, and the chuck radial direction moves in the chuck upper edge, and the end face of a relative end with insertion end is provided with the dovetail groove 6 of the claw 2 that is used to peg graft on this claw pedestal 1, for stationary jaw 2 better; Prevent that claw 2 from outwards moving in claw pedestal 1 when chuck rotates; This dovetail groove 6 is made as the dovetail groove of single interface, and towards an end of chuck hub, this claw pedestal 1 was provided with the screw mounting hole 5 of the section of being threaded that is communicated with insertion end end face and dovetail groove 6 bottom surfaces when the interface of this dovetail groove 6 was located at this claw pedestal 1 and is positioned on the adaptive chuck; Be installed with the backing-up screw 12 that is used to hold out against claw 2 in this screw mounting hole 5; Said screw mounting hole 5 comprises that also one holds the counterbore section of said backing-up screw 12 caudal peduncles, on claw pedestal 1, also is provided with to be used to prevent that claw 2 from deviating from the locking mechanism of this claw pedestal 1, and this locking mechanism is positioned at the interface place of dovetail groove 6; Comprise spring 4 and the trip 3 that cooperates with these spring 4 roof pressures; The bottom below that is positioned at dovetail groove 6 on this claw pedestal 1 is provided with the chamber 11 that holds spring 4 and trip 3, and spring 4 is arranged at the bottom of chamber 11 and the dop of said trip 3 is ejected the bottom land of dovetail groove 6, is used for and the spacing cooperation of claw 2 upper limit position grooves; The trip head is the inclined-plane towards the one side of interface direction; Face towards the dovetail groove other end is a facade, is wholely set on the trip 3 the trip head is pushed away the operating grip 8 of said dovetail groove 6 bottoms to the insertion end direction, and operating grip is provided with the annular knurl 10 of conveniently stirring operating grip.
The utility model embodiment inserts the interface of claw by the dovetail groove of claw pedestal in use, and the trip in the retaining mechanism is under the roof pressure of spring; Its dop inserts in the claw; Screw backing-up screw then, make backing-up screw hold out against claw to the direction of dovetail groove and get final product, unscrew backing-up screw during switching-over from claw pedestal insertion end; The operating grip that promotes trip pushes away the dovetail groove bottom surface of claw pedestal with the dop of trip, extracts claw out and gets final product.
The utility model is provided for holding out against the backing-up screw of claw on the claw pedestal; When claw after frequent switching-over causes the dovetail groove wearing and tearing on the claw pedestal; Only need screw backing-up screw and claw is held out against on the claw pedestal, can realize effectively fixingly, solve in the prior art after the claw pedestal weares and teares the effectively problem of stationary jaw of screw.
