The utility model content
The purpose of this utility model provides a kind of arc control device slip fingertip erecting tools, the slip fingertip can conveniently be installed and can not cause damage to the slip fingertip, can effectively boost productivity again.
For achieving the above object, the utility model adopts following technical scheme: arc control device slip fingertip erecting tools, this instrument comprises pull bar and pedestal, pull bar passes and rotates thrust and is assemblied on the pedestal, one end of pull bar has thread segment, spiral is equipped with addendum cone on the thread segment of pull bar, and the conical surface one side of addendum cone is towards pedestal; Be set with the close up device on the described pull bar between addendum cone and pedestal, close up device one end is assemblied on the pedestal, the conical surface corresponding matching of the other end and addendum cone.
The tubular construction that described close up device is surrounded by fingertip and bind round in the spring of fingertip outer peripheral face and form.
Described close up device is integral ring-shaped structure, upwards is interval with axial spring in an end week of close up device and refers to.
Described fingertip one end is provided with the flanging of L type, radially is installed with slide bar away from flared ends, and slide bar passes pedestal and is slidingly matched with pedestal.
Described addendum cone is a round platform, and each coincide and is extended with a cylinder on the both ends of the surface of round platform.
Be installed with axially stop block on the described pull bar, axially stop block is positioned at the side of pedestal away from addendum cone.
Be provided with thrust bearing between described axially stop block and the pedestal, two end faces of thrust bearing respectively with the corresponding cooperation of pedestal and axially stop block.
Described axially stop block is positive stop lug boss or position-limitting pin.
The screw rod pulling addendum cone that the arc control device slip fingertip erecting tools of such scheme adopts thrust to be installed on the pedestal carries out rectilinear motion, and addendum cone its conical surface when rectilinear motion acts on the close up end of close up device, makes the close up device carry out the outer action of rising.When rising outside the close up device, its close up end drives slip fingertip to be installed and rises synchronously, can install easily when fingertip to be slided increases to suitable installation dimension.Use this instrument that the slip fingertip is installed, need not knock the slip fingertip, the slip fingertip can be in place as long as touch the slip fingertip, installation process can not cause damage to the slip fingertip, the installation effectiveness height has satisfied the requirement of assembly technology and product quality.
In addition, the close up device that relates in the utility model can be branch body structure or overall structure.One end of its fingertip is equipped with slide bar when for the branch body structure, slide bar is used for guaranteeing the radial motion of fingertip along addendum cone, near hoop on the side face of slide bar end spring is arranged at fingertip, reverse rotation pull bar after finishing the installation task, addendum cone moves to the direction away from pedestal, and this moment is the inwardly playback respectively of each fingertip under the effect of spring.Be positioned at pedestal on the pull bar and be provided with axially stop block outward, the thrust bearing that both ends of the surface cooperate with axially stop block and pedestal respectively is installed between axially stop block and the pedestal, make when rotating rod more laborsaving away from the end face of addendum cone.

Embodiment
The embodiment 1 of Fig. 1, Fig. 2, the utility model arc control device slip fingertip erecting tools shown in Figure 3, comprise pedestal 3, be axially installed with pull bar 4 along pedestal 3, pull bar 4 ends of thread deviate from the thrust bearing installation room 13 on the pedestal 3, in the thrust bearing installation room 13 on the pedestal 3 thrust bearing 7 is installed, two end faces of thrust bearing 7 contact with pedestal 3 with pull bar positive stop lug boss 6 respectively.Pull bar 4 ends of thread are equipped with addendum cone 1, and addendum cone 1 small end face is towards pull bar handle 5.Six fingertips 12 are formed close up device 10 by spring 2,8 hoops together, and fingertip one end is provided with the flanging of L type, is provided with screwed hole 17 away from flared ends, and screwed hole 17 both sides are provided with spring mounting groove 18,19.Close up device 10 is installed between pedestal 3 and the addendum cone 1 along pedestal 3 axis, and the close up end 11 of close up device 10 is sleeved on addendum cone 1.Slide bar 9 links together by slide bar spacing hole on the pedestal 3 14 and close up device 10 screw fixed.
The embodiment 2 of the utility model arc control device slip fingertip erecting tools shown in Figure 4, the figure of itself and embodiment one is that with part its close up device 10 is overall structure, upwards is interval with six springs vertically in an end week of this close up device 10 and refers to.
Adopt the arc control device slip fingertip erecting tools of such scheme, earlier the slip fingertip is sleeved on the end that arc control device slip fingertip erecting tools is equipped with addendum cone during use, and the close up end that guarantees the close up device is positioned at slip fingertip inside, turn pull bar handle, addendum cone is moved to the pull bar handle end along the pull bar direction, this moment, the close up end of close up device under the conical surface effect of addendum cone radially rose outside slowly, the slip fingertip equally radially rises outside slowly under the effect of close up end, wait to reach the pull bar handle that stops the rotation behind the installation requirement, and the slip fingertip pushed away be contained on the contact base, and guarantee that the slip fingertip cooperates fully with contact base and put in place.Reverse rotation pull bar handle then, make addendum cone along the pull bar direction to moving away from the pull bar handle end, the close up end of close up device is inwardly motion radially, takes out arc control device slip fingertip erecting tools after reaching punctured position, finishes the once mounting task.Use the arc control device slip fingertip erecting tools of such scheme, the slip fingertip is installed, the installation effectiveness height can not cause damage to the slip fingertip, has satisfied the requirement of assembly technology and product quality.
