Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

Referring to Fig. 1 and 2, the present embodiment is a kind of for processing the sensitive drilling machine of steel watchcase, the pedestal including rectangular plate-like 1, a middle side edge of pedestal 1 is fixed with vertical bracket 11, and workbench 12 is arranged on bracket 11, and workbench 12 offers Two parallel mounting grooves 13 are additionally provided with clamping fixture seat 2 on workbench 12, and the bottom of clamping fixture seat 2 is fixed with mounting blocks and (does not mark in figure Out), mounting blocks slide against in mounting groove 13.

The bottom of clamping fixture seat 2 is equipped with mounting plate 21, and mounting plate 21 opens up along the vertical direction (not to be marked there are two through-hole in figure Out), it is equipped in through-hole and pushes against bolt 211, the head for pushing against bolt 211 is located at through-hole upper surface, pushes against the bar portion of bolt 211 Side far from head is equipped with screw thread (not shown), and bar portion passes through through-hole and is threaded with abutting nut and (do not mark in figure Out).Clamping fixture seat 2 is fixed in mounting groove 13 by pushing against bolt 211.In addition, bracket 11 is equipped with drill bit along the vertical direction 14, workbench 12 is equipped with position line 15, and the underface by drill bit 14 of position line 15, clamping fixture seat 2 perpendicular to mounting groove 13 Bottom be accordingly equipped with index line 22.Staff can determine clamping fixture seat 2 and drill bit by position line 15 and index line 22 14 relative position, convenient for adjusting.

Referring to Fig. 3 to 5, clamping fixture seat 2 is equipped with indexing means, and indexing means includes slow-speed shaft 23, and slow-speed shaft 23 is horizontally disposed, And one end is located at the inside of clamping fixture seat 2, the axis hole that the side wall that the other end passes through clamping fixture seat 2 opens up and the outside for being located at clamping fixture seat 2. Slow-speed shaft 23 is equipped with two sections of shaft shoulders, and two sections of shaft shoulders of slow-speed shaft 23 are connected to clamping fixture seat 2 in the side wall of fixture 25 respectively Outer surface, and slow-speed shaft 23 is fixed in the axial direction on clamping fixture seat 2 enables and slow-speed shaft 23 and is only capable of around own axes Rotation.Slow-speed shaft 23 is located at the removable fixture 25 for being provided with internal expansion type in one end outside clamping fixture seat 2, and fixture 25 is located at drill bit 14 Underface.

The inside of clamping fixture seat 2 offers cavity, and cavity is horizontal column.Indexing means includes planetary gear train 3, planetary gear It is 3 in cavity, and planetary gear train 3 includes sun gear 33, planet carrier 32 and ring gear 31.Wherein, planet carrier 32 is located at End of the slow-speed shaft 23 far from fixture 25, and be wholely set with slow-speed shaft 23.

Planet carrier 32 includes three planet arms 321, and planet arm 321 radial is uniformly distributed simultaneously around the axis of slow-speed shaft 23 Extend outwardly, planetary gear train 3 further includes three planetary gears 34, and three planetary gears 34 are divided into the end of three planet arms 321 End.Planetary gear 34 and planet arm 321 are rotatablely connected, and engage connection with sun gear 33.Planetary gear 34 and sun gear 33 two plane sides alignment.

Ring gear 31 is the annulus with internal tooth, and outer circumference surface and the clamping fixture seat 2 of ring gear 31 are wholely set.Ring gear 31 It is coaxial with sun gear 33 and be arranged outside with three planetary gears 34, and connection is engaged with three planetary gears 34.It is interior The number of teeth of gear ring 31 is the integral multiple of 33 number of teeth of sun gear, in addition, ring gear 31 is aligned with two plane sides of planetary gear 34.

Sun gear 33 has been wholely set high speed shaft 24, and high speed shaft 24 and slow-speed shaft 23 are coaxial.High speed shaft 24 is far from too One end of positive gear 33 passes through the side wall of clamping fixture seat 2, and end is located at the outside of clamping fixture seat 2 and has been wholely set runner 26.At a high speed Axis 24 also is provided with two sections of shaft shoulders, and two sections of shaft shoulders of high speed shaft 24 are connected to respectively inside and outside side wall of the clamping fixture seat 2 far from fixture 25 Surface, and high speed shaft 24 is fixed in the axial direction on clamping fixture seat 2, enable high speed shaft 24 and be only capable of around own axes from Turn.Referring to Fig. 6, the shaft shoulder section that high speed shaft 24 is located at outside clamping fixture seat 2 is fixed with pointer 28, and clamping fixture seat 2 is along the edge of the shaft shoulder It is provided within one week scale 27,28 face scale 27 of pointer.

At this point, can angle as needed carry out rotating wheel 26, by runner 26 rotation drive 33 turns of sun gear Dynamic, since ring gear 31 is fixed, planetary gear 34 drives slow-speed shaft 23 and fixture 25 to be rotated with planet carrier 32, due to The number of teeth of ring gear 31 be 33 number of teeth of sun gear integral multiple, i.e., the transmission ratio of the planetary gear train 3 be the multiple add one it is whole Number.At this point, the angle of runner 26 is adjusted in the circle number and scale 27 by runner 26, so that fixture 25 turns over the mistake of angle Difference is smaller, and fixes the setting of device so that angle will not be changed because of external force by adjusting the fixture 25 completed.

See back Fig. 2, for make fixture 25 complete angle adjusting after can be fixed, prevent because the external world influence due to turn Dynamic, clamping fixture seat 2 is equipped with fixed device.Since fixture 25 is not easy to be fixed in itself, fixed device includes and fixture 25 turntables rotated simultaneously with angular speed.Turntable is ring-type, between fixture 25 and the side wall of clamping fixture seat 2, turntable Inner ring sleeve is set on slow-speed shaft 23, and inner ring offers locating slot (not shown), is fixed on slow-speed shaft 23 and locating slot The locating piece (not shown) of cooperation, locating piece and locating slot are fitting to connection, so that turntable is fixed on slow-speed shaft 23.This When, since turntable is coaxial with slow-speed shaft 23 and fixed, and fixture 25 is coaxial with slow-speed shaft 23 and fixed, therefore can carry out to turntable Positioning achievees the purpose that indirectly to position fixture 25.

To consolidate the turntable after positioning without rotating easily, fixed device further includes hold assembly 4, clamping Component 4 is located at the underface of turntable, and hold assembly 4 includes two symmetrically arranged clamps 41, and clamp 41 includes 42 He of plier Interconnecting piece 43, plier 42 are fixedly connected in obtuse angle with interconnecting piece 43, and the corner and the clamping fixture seat 2 are rotatablely connected.Two institutes The end for stating clamp 41 is close, so that two clamps 41 are in a pair of of bracket shape.The fixed device further includes described for driving The elastic driving device of hold assembly 4.

Interconnecting piece 43 is rotatably connected to idler wheel 44 far from one end of plier 42, and driving device includes cylinder 45, and cylinder 45 wraps It includes piston rod (not marked in figure), the end of piston rod is fixed with the jacking block 46 of wedge shape, and the tip of jacking block 46 is located at two idler wheels Between 44.When cylinder 45 starts, piston rod stretches out, and jacking block 46 applies pressure to two clamps 41, so that the rolling of two clamps 41 44 separation of wheel has separation trend.Since the interconnecting piece 43 and clamping fixture seat 2 of interconnecting piece 43 and plier 42 are rotatablely connected, two Plier 42 moves toward one another or has the tendency that adjacent to each other, and is clamped turntable by two pliers 42.To further increase plier 42 To the clamping effect of turntable, non-slip mat (not marking in figure) is equipped with two opposite sides of plier 42.
