Fig. 5 is the centre hole that present clip clamping excentric shaft processes this axle d diameter shaft section (little end).
Embodiment
Such as Fig. 1, the excentric shaft 9 that clamp has two different diameter axle sections, and namely diameter is the diaxon section of D, d, and D > d, and the width between centers of this diaxon section is E, and namely eccentricity is E. Present clip for being clamped by this excentric shaft 9 forms primarily of substrate 1, vertical plate 2, V shape block 3, rotating shaft 4, compressing unit 5, first steady brace 6 and the 2nd steady brace 7.
Vertical plate 2 is vertically connected on substrate 1, thus form a mounting bracket, this mounting bracket is connected on corresponding lathe by substrate 1, such as, on numerical control drilling machine, V shape block 3 is rotating to be connected on vertical plate 2, V shape block 3 can be opposed plate 2(and whole mounting bracket mutually) rotate, rotary centerline O is arranged on below the V shape groove center line N of V shape block, and the vertical range apart from this medullary ray N is 1/2E, such as Fig. 2, V shape block 3 is for positioning the center of the d diameter shaft section of excentric shaft 9, and namely the d diameter shaft section of excentric shaft 9 is placed in the V shape groove of V shape block 3. On the upper surface that 2nd steady brace 7 is arranged on V shape block 3 or lower surface, with to excentric shaft 9 circumferential position position, make D, d two medullary ray N of vertical join line B1B2 and V shape groove of diameter shaft section axis vertical.
Such as Fig. 3, in order to make rotating V shape block 3 locate on vertical plate 2, vertical plate 2 is provided with at least one first pilot hole, this pilot hole is R apart from the distance of rotary centerline O, on the end face that V shape block 3 is parallel with vertical plate 2, it is provided with two the 2nd pilot holes that circumferential position differs 180 �� simultaneously, this two the 2nd pilot hole is blind hole, and the distance apart from rotary centerline O is also R, like this when V shape block 3 rotates 180 degree around rotary centerline O, the first pilot hole coaxial line on one of them the 2nd pilot hole and vertical plate 2 is formed through communicating pores, first steady brace 6 is plugged in this communicating pores, V shape block 3 is positioned on vertical plate 2. in order to prevent steady brace 6 to pilot hole repeatedly grafting formed abrasion, first and second pilot hole is fixedly connected with first and second locating sleeve 61,62 respectively.
V shape block 3 is connected on vertical plate 2 by gyro black assembly 4 is rotating, and this gyro black assembly 4 comprises rotating shaft 40, first axle sleeve 41 and the 2nd axle sleeve 42, and rotating shaft 40 is rotatably connected in the first axle sleeve 41; In order to realize being rotationally connected of V shape block 3, it is respectively equipped with shaft hole and rotation hole corresponding to described rotary centerline O position at vertical plate 2 and V shape block 3, first axle sleeve 41 and the 2nd axle sleeve 42 are fixedly connected in shaft hole and rotation hole respectively, and V shape block 3 is sheathed on the first axle sleeve 41 by the 2nd axle sleeve 42 and is rotatably connected on vertical plate 2.
Such as Fig. 4, further, in order to make V shape block 3 along rotation hole centerline direction without movement, rotating shaft 4 is provided with the location shaft shoulder 43 and arranges screw thread 44 at the one end of this rotating shaft, rotating shaft is through the first axle sleeve 41 being connected on vertical plate 2, and with the shaft shoulder 43 axial location on vertical plate 2, if the threaded hole 35 in the rotation hole on the one end of threaded rotating shaft 4 and V shape block 3 spins, V shape block 3 is axially connected on vertical plate 2 with being defined.
Two compressing units 5 are along the V shape groove directional spreding of V shape block 3, and each compressing unit 5 is arranged on the V shape channel opening end of V shape block 3, rotates with V shape block 3. in the present embodiment, V shape groove directional spreding along V shape block 3 has two compressing units 5. each compressing unit 5 comprises pressing plate 51, depression bar 52, supporting bar 53 and nut, two supporting bars 53 are separately fixed at the both sides of the V shape channel opening end of V shape block 3, supporting bar 53 center is provided with threaded hole, two supporting bars 53 are separately fixed at the side of the V shape channel opening end of V shape block 3, the both sides of pressing plate 51 and central position are respectively equipped with and connect hole and screw, pressing plate 51 is bearing on two supporting bars 53, two coupling screws 54 are each passed through in the screw that corresponding connection hole is screwed in corresponding supporting bar 53 center, pressing plate 51 is made to be connected on supporting bar 53, depression bar 52 is screwed in the screw of pressing plate 51 central position, in the d diameter shaft section of the excentric shaft 9 clamped by the compression of its end.
In order to reduce V shape block 3 with material and reduce machining face, the V shape channel opening end both sides of V shape block 3 are set to boss 34 respectively, and in compressing unit 5, supporting bar 53 is connected on boss 34.
Present clip is plugged the first steady brace 6 before excentric shaft clamping, tie down screw 43, excentric shaft is placed in V shape from V shape block 3 upper end, and the d diameter shaft section of excentric shaft is located in V shape groove, the D diameter shaft section of excentric shaft is placed in the upper end of V shape block 3, eccentric rotation axis makes D diameter shaft section touch the 2nd steady brace 7, so that D diameter shaft section circumference location, it is vertical with rotary centerline O that this positioning states makes the central vertical of diaxon section on excentric shaft connect B1B2. Then, screw depression bar 52, make excentric shaft 9 by clamping in fixture, now with B1 and the B2 centre hole of numerical control drilling machine or CNC milling machine processing excentric shaft D diameter shaft section. After the centre hole of D diameter shaft section (holding greatly) machines, unclamp locking screw 43, pull out the first steady brace 6, V shape block 3, compressing unit 5 and excentric shaft 9 are rotated 180 degree, such as Fig. 5, now process B1 and the B2 centre hole of excentric shaft d diameter shaft section. Thus, the processing of centre hole that the two of excentric shaft are not concentricity only needs clamped one time to add last fixture upset just can to complete, be easy to operate, greatly improve clamping efficiency, simultaneously owing to clamped one time is located, it is to increase working accuracy.
