Detailed description of the invention
Fig. 1 is a kind of internal spline gear-shaping clamp cross-sectional view.
Fig. 2 is the structural schematic diagram of drill holder 9.
Specific embodiment
Embodiment is as shown in Figure 1, a kind of internal spline gear-shaping clamp, for clamping workpiece 2；Including pedestal 1, pedestal 1 is equipped with
Circular groove, groove are equipped with coaxial sleeve cylinder base 3, positioning seat 5 are equipped in receiver 3, between positioning seat 5 and receiver 3
Equipped with 4 valve head number of petaloid collet in petaloid collet 4(Fig. 1 be odd number when cross-sectional view, certain 4 valve head number of petaloid collet
It can be even number)；It is the mutually matched conical surface between the top of petaloid collet 4 and 3 top of receiver, the conical surface is to 3 inside of receiver
Inclination；It is equipped with drill holder 9 between 4 top of petaloid collet and workpiece 2, drill holder 9 is elastic construction, and 9 structure of drill holder can be
Shown in Fig. 2,9 circumference of drill holder is axially equipped with a slot, slot opposite is equipped with arc groove, and drill holder 9 is along cutting
Seam and the arc groove line of centres axisymmetricly figure are marked with plastic cement in slot and arc groove；4 bottom of petaloid collet passes through spiral shell
Bolt or screw 13 are connect with pull-up pole socket 6, are wherein machined with through-hole on receiver 3 and positioning seat 5, are equipped with bushing 12 in through-hole,
Bolt or screw 13 pass through bushing 12 and do not occur actually to contact with it；It pulls up pole socket 6 to be arranged below receiver 3, pull-up
6 bottom end of pole socket is fixedly connected with lower pull rod 7 by connector sleeve 8, drives petaloid collet 4 to move downward clamping by pull-up pole socket 6
Drill holder 9, and then clamp workpiece；Dustproof cover 10 is equipped at the top of receiver 3；6 top of pull-up pole socket is also machined with leakage bits hole A11,
