Detailed description of the invention
Such as Fig. 1, eccentric shaft 9 to be clamped has two different diameter shaft sections, two shaft parts of the most a diameter of D, d, and D ＞ d, the centre-to-centre spacing of this two shaft part be E, i.e. eccentric throw be E.Present clip for clamping this eccentric shaft 9 is mainly made up of substrate 1, riser 2, vee-block 3, rotating shaft 40, compressing unit the 5, first alignment pin 6 and the second alignment pin 7.
Riser 2 is vertically connected on substrate 1, it is consequently formed a mounting bracket, this mounting bracket is connected on the lathe of correspondence by substrate 1, such as on numerical control drilling machine, vee-block 3 is rotatablely connected with on riser 2, make vee-block 3 can rotate relative to riser 2 (the most whole mounting bracket), rotary centerline O is arranged on below the V-shaped groove centrage N of vee-block, and the vertical dimension away from this centrage N is 1/2E, such as Fig. 2, vee-block 3 is for positioning the center of the d diameter shaft part of eccentric shaft 9, i.e. the d diameter shaft part of eccentric shaft 9 is placed in the V-shaped groove of vee-block 3.Second alignment pin 7 is arranged on upper surface or the lower surface of vee-block 3, with to eccentric shaft 9 circumferential position position, make D, d two vertical join line B1B2 of diameter shaft part axis vertical with the centrage N of V-shaped groove.
Such as Fig. 3, in order to make rotating vee-block 3 position on riser 2, riser 2 is provided with at least one first hole, location, the distance of this location pitch-row rotary centerline O is R, on the end face that vee-block 3 is parallel with riser 2, it is provided with circumferential position simultaneously differs two second holes, location of 180 °, this hole, two second location is blind hole, and the distance away from rotary centerline O is also R, so when vee-block 3 rotates 180 degree around rotary centerline O, one of them second hole, location is formed through through hole with the first hole, location coaxial line on riser 2, first alignment pin 6 is plugged in this through hole, vee-block 3 is made to be positioned on riser 2.In order to prevent the abrasion that the grafting repeatedly of hole, location is formed of alignment pin 6, in first and second hole, location, it is respectively fixedly connected with first and second positioning sleeve 61,62.
Vee-block 3 is rotatablely connected with on riser 2 by gyro black assembly 4, and this gyro black assembly 4 includes rotating shaft the 40, first axle sleeve 41 and the second axle sleeve 42, and rotating shaft 40 is rotatably connected in the first axle sleeve 41；In order to realize being rotationally connected of vee-block 3, it is respectively equipped with shaft hole and rotation hole corresponding to described rotary centerline O position at riser 2 and vee-block 3, first axle sleeve 41 and the second axle sleeve 42 are respectively fixedly connected with in shaft hole and rotation hole, and vee-block 3 is sheathed on the first axle sleeve 41 by the second axle sleeve 42 and is rotatably connected on riser 2.
Such as Fig. 4, further, in order to make vee-block 3 along rotation hole centerline direction without movement, rotating shaft 40 is provided with the location shaft shoulder 43 and is threaded 44 at the one end of this rotating shaft, rotating shaft is through the first axle sleeve 41 being connected on riser 2, and axially position on riser 2 with the shaft shoulder 43, if the one end of threaded rotating shaft 40 spins with the screwed hole 35 in the rotation hole on vee-block 3, make vee-block 3 be connected on riser 2 with being axially defined.
Two compressing units 5 are arranged on the V-shaped groove opening of vee-block 3 along the V-shaped groove directional spreding of vee-block 3, each compressing unit 5, rotate with vee-block 3.In the present embodiment, the V-shaped groove directional spreding along vee-block 3 has two compressing units 5.Each compressing unit 5 includes pressing plate 51, depression bar 52, support rod 53 and nut, two support rods 53 are separately fixed at the both sides of the V-shaped groove opening of vee-block 3, support rod 53 center is provided with screwed hole, two support rods 53 are separately fixed at the side of the V-shaped groove opening of vee-block 3, the both sides of pressing plate 51 and center are respectively equipped with connecting hole and screw, pressing plate 51 is bearing in two support rods 53, two attachment screws 54 are each passed through the connecting hole of correspondence and are screwed in the screw at corresponding support rod 53 center, pressing plate 51 is made to be connected in support rod 53, depression bar 52 is screwed in the screw of pressing plate 51 center, on the d diameter shaft part of the eccentric shaft 9 clamped by the compression of its end.
In order to reduce using material and reducing machining face of vee-block 3, the V-shaped groove opening both sides of vee-block 3 are respectively set to boss 34, and in compressing unit 5, support rod 53 is connected on boss 34.
Present clip is plugged the first alignment pin 6 before eccentric shaft clamping, tie down screw 43, eccentric shaft is placed in V-arrangement from vee-block 3 upper end, and make the d diameter shaft part of eccentric shaft position in V-shaped groove, the D diameter shaft part of eccentric shaft is placed in the upper end of vee-block 3, eccentric rotation axis makes D diameter shaft part touch the second alignment pin 7, so that D diameter shaft part is circumferentially positioned, it is vertical with rotary centerline O that this positioning states makes the center of two shaft parts on eccentric shaft vertically connect B1B2.Then, screw depression bar 52, make eccentric shaft 9 by clamping in fixture, now process B1 and the B2 centre bore of eccentric shaft D diameter shaft part by numerical control drilling machine or CNC milling machine.After the centre bore of D diameter shaft part (end greatly) machines, unclamp lock-screw 43, pull out the first alignment pin 6, vee-block 3, compressing unit 5 and eccentric shaft 9 are rotated 180 degree, such as Fig. 5, now process B1 and the B2 centre bore of eccentric shaft d diameter shaft part.Thus, the processing of the most concentric centre bore of eccentric shaft only needs clamped one time to add last fixture upset just can to complete, be easy to operate, be greatly improved clamping efficiency, simultaneously because clamped one time positions, improve machining accuracy.
