Specific embodiment
In order to make the present invention realize technological means, creation characteristic, reach purpose and effect more clearly and be apparent to,
The present invention is further elaborated with reference to the accompanying drawings and detailed description:
As shown in Figure 1-3, the utility model proposes a kind of for processing the fixture of 9 internal tooth of transmission shaft fixed knot, including
Clamp bottom board 1, installation sleeve 2, rotating seat 3, clamp body 4 and positioning bolt 6.
The clamp bottom board 1 is equipped with annular groove, and the installation sleeve 2 includes that one end is fixed on clamp bottom board 1 and ring
The coaxial cylinder of shape sliding slot and both ends are connected to the worm screw 8 of cylinder interior and close annular groove edge, the rotation by bearing
Swivel base 3 includes two sections of cylinders connected vertically, and the rotating seat 3 is equipped with the through-hole for accommodating fixed knot 9, and the rotating seat 3 is located at
Inside installation sleeve 2 and upper cylindrical outer surface is connect with installation sleeve 2 by bearing, and 3 bottom end of rotating seat passes through annular
Sliding slot and clamp bottom board 1 and bearing are rotatablely connected；The rotating seat 3 is additionally provided with close to the outer surface of clamp bottom board 1 matches with worm screw 8
The worm gear of conjunction, so that the rotating seat 3 rotates in annular groove when rotary worm 8.
The clamp body 4 is bolted in 3 upper surface of rotating seat, centre be equipped with place fixed knot 9 and with rotating seat 3
Coaxial through-hole is additionally provided with the positioning screw hole connecting with positioning bolt 6,6 screw portion two parts rod segment structure of positioning bolt
At being the screw thread cooperated with the positioning screw hole by the part of close end, top is the polished rod cooperated with through-hole on fixed knot 9.
Wherein smooth bar part diameter is slightly larger than the major diameter of threaded rod, and smooth bar part length is less than the depth of 9 outer circle hole of fixed knot, and it is fixed to make
The position installation of bolt 6 is more simple.
The clamp bottom board 1 is equipped with support limit bolt 7 at 3 center of rotating seat, and 7 bar portion of support limit bolt is by two
Part is constituted, and is threaded rod close to end rod segment, and 7 end face of support limit bolt is equipped with and the smallest end of 9 radius of fixed knot
The Blind locating holes of (end portion i.e. after fixed knot installation) cooperation, another part rod segment of 7 bar portion of support limit bolt is half
Diameter is greater than the polished rod of the threaded rod, and clamp bottom board 1 is equipped with the through-hole cooperated with each position of support limit bolt 7, i.e., first has
One section of hole cooperated with polished rod is as dowel hole, then has the threaded hole of one section with shaft.Support limit bolt 7 and fixed
Position 6 place end of bolt supports jointly, mitigates the pressure at 6 place end of positioning bolt and prevents deformation, prevented also from 9 lower part of fixed knot
Shaft end shake, for longer fixed knot 9, effect is particularly evident and important, 7 polished rod portion of support limit bolt
Divide and cooperate precision higher with the hole on clamp bottom board 1, so that support limit bolt 7 is played the positioning of the limit to 9 end of fixed knot and make
With so that the concentricity as much as possible after raising fixed knot clamping, guarantees the precision of Gear Shaping.
In above scheme, the implementation process of the utility model is as follows: first passing through peripheral 5 fixing clamp of bolt specific 4, then puts
Entering fixed knot 9 makes its both ends be respectively aligned to the blind hole and positioning screw hole, and fixed by positioning bolt 6, finally tightens support
Caging bolt 7 is completed to be loaded.Using machined 9 outer circle hole of fixed knot and the part shaft shoulder realization be loaded, bar portion lateral surface not by
Power ensure that machining accuracy is not destroyed；It drives fixed knot 9 to rotate by turbine and worm 8, completes the overall processing of tooth；Solid
Surely support limit bolt 7 is added at the non-processing end of section 9, is that support is more stable, while positioning is more accurate.
Further, annular groove bottom section semicircular in shape, 3 bottom of rotating seat are and the annular groove
The semicircle of cooperation.Annular groove bottom section semicircular in shape, increases forced area, reduces pressure, alleviates rotating seat 3
Abrasion between annular groove.
