Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described further.
Refer to Fig. 1 to Fig. 4, the utility model relates to a kind of thimble clamping jig, comprise foundation 1, the height adjusting blocks 5 that can slide up and down along foundation 1 side, be located at fixing briquetting 2 above foundation 1, to be located at above height adjusting blocks 5 and be fixed on the movable holddown 3 of fixing briquetting 2 side, described fixing briquetting 2 is provided with spacing hole 22 towards the side of movable holddown 3, and described movable holddown 3 is provided with the guide pillar 32 that can be inserted in spacing hole 22.
Fixing briquetting 2 is screwed and is arranged on above foundation 1, fixing briquetting 2 is respectively equipped with a screwed hole 21, two spacing holes 22 and two springs 23 towards the Shang Cong center, side of movable holddown 3 to two ends, on described side, vertical direction is also provided with at least one " V " type groove or flat inverted draw cut 24, and " V " type groove or flat inverted draw cut 24 can the thimbles 7 of vertical display different-diameter size.On the side of movable holddown 3, corresponding screwed hole 21 is provided with a tapped through hole 31 and two guide pillars 32 with the position of spacing hole 22 and is located at the groove 33 of guide pillar 32 both sides for fixing spring 23, screwed hole 21 is coaxial with tapped through hole 31, guide pillar 32 is inserted in spacing hole 22 removable, the spacing hole 22 set up and guide pillar 32 with the use of, thimble 7 is only moved in parallel when locking, therefore the precision of thimble can not be affected, and movable holddown 3 can be automatically springed open when taking out thimble 7 by the spring 23 compressed, eliminating and manually moving operation.
The side of movable holddown 3 is provided with pressing plate handle 4, pressing plate handle 4 comprises the first screw rod 41 and is located at first screw rod 41 one end Chengs “ ∟ " rocking handle 42 of shape; the end of thread of the first screw rod 41 is inserted in screwed hole 21 through tapped through hole 31; movable holddown 3 can be moved to fixing briquetting 2 by hand rocking handle 42, realize the effect of fixed clamp thimble 7.Due to the spacing hole 22 simultaneously set up and guide pillar 32 with the use of, make clamping screw be reduced to one, and screw is fixedly connected with handle, eliminates manual wrench operation.One end radial direction of rocking handle 42 runs through the first screw rod 41 and can relative sliding, when after clamping thimble 7, due to deadweight reason, that rocking handle 42 is slided down to is minimum, pressing plate handle 4 is designed to slidably act on, avoid the hand position that rocking handle 42 occurs when locking because of different-diameter thimble different, the pressing plate handle 4 caused is higher than machined surface.
The side of foundation 1 is provided with the dovetail groove slide rail 11 of vertical direction, and the width of the horizontal cross-section of dovetail groove slide rail 11 broadens from inside to outside gradually, and described cross section defines antiparallelogram shape.Height adjusting blocks 5 is located at the side of foundation 1, and on the end face of height adjusting blocks 5, corresponding dovetail groove slide rail 11 offers dovetail groove 51, and dovetail groove slide rail 11 cooperation is arranged in dovetail groove 51, and height adjusting blocks 5 can vertically be slided by foundation 1 relatively.
The another side of height adjusting blocks 5 relative to dovetail groove 51 is provided with spacing handle 6, spacing handle 6 comprises and runs through height adjusting blocks 5 and the second screw rod 61 passed at dovetail groove 51 center and the rocking bar 62 being located at second screw rod 61 one end, height adjusting blocks 5 moves up and down defensive position and swaggers bar 62, second screw rod 61 is screwed in and compresses dovetail groove slide rail 11, realizing height adjusting blocks 5 with this is fixed on foundation 1, and height adjusting blocks 5 serves the effect of location, support pin.Rocking bar 62 also radial direction runs through second screw rod 61 one end and can relative sliding, avoids the bottom of spacing handle 6 lower than foundation 1, affects the use of height adjusting blocks 5.Come off from foundation 1 lower end to prevent height adjusting blocks 5, be designed with a limited screw 12 in dovetail groove slide rail 11 lower end, offer stopper slot 52, when height adjusting blocks 5 slides to bottom at dovetail groove 51 lower end correspondence position simultaneously, limited screw 12 slides in stopper slot 52, prevents from coming off.
Use procedure of the present utility model, first by height adjusting blocks 5 up-down adjustment, after determining desired height, screws spacing handle 6; The bottom of thimble props up height adjusting blocks 5 and in " V " the type groove being placed on fixing briquetting 2 or flat inverted draw cut 24, then hand press handle 4, makes movable holddown 3 press to fixing briquetting 2 and clamp thimble 7, carry out grinding to thimble 7; After grinding completes, unscrew press handle 4, spring 23 flicks movable holddown 3, can take out thimble 7.
With batch thimble need not re-adjustments height adjusting blocks 5 height, direct clamping thimble is processed; The thimble of different batches needs to readjust height adjusting blocks 5 and processes highly again.
Above specific embodiment is only in order to illustrate structure of the present utility model, and those of ordinary skill in the art can make various deformation and change under design of the present utility model, and these distortion and change include within protection domain of the present utility model.
