Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
For processing the frock clamp of ring gear, as shown in Figure 1 and Figure 2, including the hollow base 1 fixed with numerically-controlled machine tool,
It is fixedly installed in the clamping fixture seat 11 of 1 upper surface of hollow base, clamping fixture seat 11 runs through vertically offers slip hole 12, in slip hole 12
Sliding is connected with sliding column 13, and sliding 13 top of column is integrally formed with collet 14, and 14 outside of collet is whole in a circular table shape, and roundlet
End and sliding column 13 are fixed, and big nose circle offers embedded hole 15, collet 14 equidistantly opened up along embedded hole 15 there are six isolate
Slot 16,11 upper surface bolt of clamping fixture seat are fixed with tightening ring 17, and the interior circular diameter of tightening ring 17 is greater than the straight of the small nose circle of collet 14
Diameter, and it is less than the diameter of big nose circle, the cylinder 18 slided for controlling sliding column 13 is provided in hollow base 1.
In the initial state, the piston rod of cylinder 18 stretches out in sleeve to the utility model, thus to sliding column 13 provide to
On support force, collet 14 is not affected by the active force of tightening ring 17 under this state, be in open configuration；When needing clamping ring gear
When, ring gear is directed in the embedded hole 15 of collet 14, and from top to bottom press ring gear, force it to be embedded in embedded hole 15, most
Sliding column 13 is pulled to move down by cylinder 18 afterwards, sliding column 13 drives collet 14 to move down during moving down, collet 14 during this
Extrados push against in the inner peripheral surface of tightening ring 17, to generate inside tightening force to collet 14 by tightening ring 17, in turn
It forces collet 14 that elastic deformation occurs and clamps ring gear；In conclusion pullling cunning by cylinder 18 after the placement for completing ring gear
It moves column 13 to move down, to realize the clamping of ring gear, clamps ring gear compared to scroll chuck in common technology means, be not necessarily to work
People turns spanner insertion square hole by spanner, reaches and clamps more convenient technical effect, meanwhile, in the clamp state, collet
14 effectively improve clamping stability compared to the point contact of three chucking chuck in the outer circumference surface that multiple arc surfaces are adjacent to ring gear.
Numerically-controlled machine tool inevitably results from vibration in work process, to avoid causing because of vibration sliding column 13 from occurring
Rotation, as shown in Figure 2 and Figure 3, clamping fixture seat 11 along the length direction of slip hole 12 open up it is limited turn sliding slot 19, slide the circle of column 13
Circumferential surface turns raised line 20 integrally formed with the limit for turning 19 movable fit of sliding slot with limit, so that turning raised line 20 by limit turns sliding slot 19 with limit
Between sliding cooperation, do not influence slide 13 longitudinal sliding motion ability of column under the premise of, effectively prevent sliding column 13 with itself axis
Line rotates for center of rotation.
Its outside diameter of the ring gear of different model may have differences, for the dress of the ring gear of adaptation different model
Folder, as shown in Figure 1, Figure 4, Figure 5,1 upper surface of hollow base is rounded, and angularly opens up centered on the center of circle that there are four T shapes
Slot 21, the interior sliding of T-slot 21 are connected with bolt 22, and 11 periphery bottom end of clamping fixture seat is integrally formed annulate lamella 23, and ring flat-plate 23 opens up
There is the notch 24 of the threaded portion insertion for bolt 22, bolt 22 has been threadedly engaged nut 25；When needing in clamping different model
When gear ring, by nut 25 by backing out on bolt 22, and slide bolt 22 disengages it from notch 24, separates cylinder 18 and sliding column
After 13 connection, clamping fixture seat 11 can be unloaded on hollow base 1；The clamping fixture seat 11 with corresponding collet 14 is taken, and
It is placed on 1 upper surface of hollow base, and connects cylinder 18 and sliding column 13, slide bolt 22 is embedded in it in notch 24,
Finally tighten the replacement that nut 25 completes clamping fixture seat 11；In conclusion there is the clamping fixture seat 11 of corresponding collet 14 by replacement, from
And the clamping of the ring gear of different model is adapted to, and then improve the adaptability of the utility model.
When replacing clamping fixture seat 11, therefore, to assure that the axis collinear of cylinder 18 and sliding column 13, for convenient for alignment cylinder 18
With sliding column 13, as shown in Figure 4, Figure 5,23 lower end surface of ring flat-plate offers positioning ring groove 29, and 1 upper surface of hollow base is integrally formed
There is the positioning ring 30 with 29 movable fit of positioning ring groove, to realize that clamping fixture seat 11 is installed by positioning ring groove 29 and positioning ring 30
The restriction of position, and then convenience is provided for alignment cylinder 18 and sliding column 13.
Cylinder 18 is realized in the following way with sliding column 13 and is detachably connected in the utility model, as shown in Figure 2 and Figure 3,
18 top of cylinder socket and screw bolt reinforcing has an inner screw sheath 26, sliding 13 lower end surface of column integrally formed with 26 screw thread of inner screw sheath
The threaded post 27 of cooperation rotates clockwise clamping fixture seat 11 and drives screw thread when needing to disconnect cylinder 18 and sliding the connection of column 13
Column 27 rotates synchronously, so that threaded post 27 is gradually screwed out into inner screw sheath 26, it is right when needing to connect cylinder 18 and threaded post 27
Quasi- threaded post 27 and inner screw sheath 26, and rotate counterclockwise, so that threaded post 27 is screwed in inner screw sheath 26, complete cylinder 18 with
Slide the connection of column 13；The detachable of column 13 and cylinder 18 is slid in conclusion realizing by threaded post 27 and inner screw sheath 26
Connection, structure is simple and operation is convenient.
