Between be provided with clamping structure.
Further, described drive mechanism includes servomotor and the decelerator being connected, decelerator
Output shaft be connected with drive dog.
Described base is provided with casing, and drive mechanism is located in casing.
Described clamping structure includes the convex chuck being located on driven chuck and is located at cylinder piston rod
The recessed chuck of end, convex chuck and recessed chuck are suitable.
It is equipped with open slot in described drive dog and driven chuck, open slot is provided with and can take
Go out and the tooth set suitable with torsion bar end splined section.
Described driven chuck is located in gripper shoe, and base is provided with track, and gripper shoe can be along track
Setting in orbit of movement.
It is connected by crawler belt between described servomotor and decelerator.
Described driven chuck is provided with the action bars of rotation convenient to operate.
Described tooth set external shape is square structure, and open slot is the side suitable with tooth set shape
Shape groove.
Described base is provided with fixed block, and fixed block is provided with screwed hole, and threaded rod passes screw thread
Hole is connected with gripper shoe.
The present invention compared with prior art, has the advantage that
Splined section by the fixing torque arm two ends of tooth set, it is to avoid during pretwist, splined section is subject to
Damage, the splined section at torque arm two ends can be protected；When torque arm is installed, driven chuck is permissible
360 degree of rotations are adjusted, and it is easy that torque arm installs positioning action, and pretwist operating efficiency is high.

Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention to the present invention
It is described in further detail.
As shown in Figure 1 to Figure 3, this is used for the equipment of torque arm pretwist, including base 1,
The drive dog 7 for positioning torque arm and driven chuck 14 relatively it is provided with on base 1, right
During torque arm 16 pretwist, drive dog 7 rotates, and driven chuck 14 maintains static；At base 1
Being provided with the drive mechanism for driving drive dog to rotate, base 1 is provided with oil cylinder 11,
The clamping fixing by frictional force it is provided with between piston rod end and the driven chuck 14 of oil cylinder 11
Structure.
Drive mechanism is fixed on base 1 one end, and drive mechanism includes servomotor 4 and decelerator
6, be connected by crawler belt 5 between servomotor 4 with decelerator 6, the output shaft of decelerator and
Drive dog 7 is connected.Base 1 is provided with casing 3, and drive mechanism is located in casing 3, right
Drive mechanism is protected, and drive dog is stretched out from casing.
Driven chuck 14 sets on the supporting plate, and base is provided with track 8, and gripper shoe can be along rail
What road moved sets in orbit.Specifically, track is T-type structure, be provided with below gripper shoe with
The T-shaped chute that track is suitable, on base, the other end is provided with fixed block 2, on fixed block 2
Being provided with screwed hole, threaded rod 9 one end is connected through screwed hole with gripper shoe, the threaded rod other end
It is provided with handwheel.Rotation hand wheel, drives driven chuck to move on base, adjust drive dog and
Distance between driven chuck, corresponding with torque arm length.
