"T"-shaped through hole is answered to be provided with tapped through hole, the T-shaped screw leads to through the screw thread on the "T"-shaped through hole and cantilever arm on turbine head
Turbine head is fixed on cantilever arm by hole through locking nut, and the locking for producing T-shaped screw and locking nut is improved to original locking
2 times of nut lock clamp force, substantially increase the service behaviour and operating accuracy of lathe.
The present invention can be provided with left tightening piece, right tightening piece, positioning key, alignment pin and locking screw between cantilever arm and rotary disk
Bar, the boss of the cantilever arm is central axial to be at least interval with two grooves, the groove squarely, the rotary disk side
Respective slot center, which is provided with screwed hole, the groove, is provided with left tightening piece and right tightening piece, the left tightening piece and right tensioner
Located key positioning in the middle of block, the located pin in upper end is fixed together, and the right tightening piece lower sides are provided with tapped through hole, institute
Tie down screw is stated inconsistent through the tapped through hole and left tightening piece on the screwed hole and right tightening piece on rotary disk, so that a left side is risen
Tight block and right tightening piece contradict left tightening piece and the lateral surface of right tightening piece and the recess sidewall of cantilever arm with respect to spreading
And lock.
The present invention is due to using said structure, with rational in infrastructure, stable work in work, coupling mechanism force multiplication, operating accuracy
The advantages of height, convenient disassembly.

Embodiment：
The present invention is further described below in conjunction with the accompanying drawings：
As shown in accompanying drawing 1,2, a kind of locking device of radial milling machine, including turbine head 8, cantilever arm 2 and rotary disk 1, its
It is characterised by between turbine head 8 and cantilever arm 2 being provided with T-shaped screw 9 and locking nut 10, the both sides of the turbine head 8 difference circumference is equal
At least three "T"-shaped through holes are laid with, the "T"-shaped through hole is concentric by big footpath cylindrical hole 11 and path cylindrical hole 12
It is interconnected and forms, and the big footpath cylindrical hole 11 of "T"-shaped through hole and the axial line of path cylindrical hole 12 are by turbine head center
Outward radial is set, and the "T"-shaped through hole of the end both sides of cantilever arm 2 correspondence is provided with tapped through hole, and the T-shaped screw 9 passes through whirlpool
Turbine head 8 is fixed on cantilever arm 2 by the tapped through hole on "T"-shaped through hole and cantilever arm 2 in wheel head 8 through locking nut 10,
The locking for producing T-shaped screw 9 and locking nut 10 is improved to 2 times of former locking nut coupling mechanism force, substantially increases lathe
Service behaviour and operating accuracy.It is of the present invention that left tensioner can be provided between cantilever arm 2 and rotary disk 1 as shown in accompanying drawing 3,4,5
Block 3, right tightening piece 5, positioning key 4, alignment pin 7 and tie down screw 6, the lower end of cantilever arm 2 are provided with boss, boss both sides difference
Provided with the dovetail groove being engaged with dovetail mount, cantilever arm 2 is plugged through dovetail groove and the dovetail mount of the upper end of rotary disk 1, described to stretch
