Specific embodiment
The present invention will be further described with specific embodiment with reference to the accompanying drawing.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of clamping device clamping electrical body, it is suitable for clamping such as insulator one
The round electrical body of class smoother, the clamping jaw 2 of left and right two for specifically including base shaft 1, being oppositely disposed in base shaft front end, clamping jaw packet
It includes arc-shaped grip sleeve 21, slideably fit in the flexible core bar 22 in grip sleeve, the rear end of grip sleeve passes through
Shaft is hinged on the front end of base shaft.In order to position clamping jaw, torsional spring can be arranged in we in shaft, and one end of torsional spring pins retaining sleeve
Pipe, the other end pins base shaft, so that torsional spring be made grip sleeve can be driven to laterally rotate.Correspondingly, it would be desirable in retaining sleeve
Setting can limit the position limiting structure for the rotational angle that grip sleeve laterally rotates between pipe and base shaft, and position limiting structure includes setting
Spacer pin 11 in base shaft front end.In this way, when clamping jaw is laterally rotated with respect to base shaft, the outside of the grip sleeve of clamping jaw
By spacer pin blocking and limit.
It should be noted that the side that clamping jaw is arranged in base shaft is known as front side in the present embodiment, the side far from clamping jaw
Referred to as rear side.
Furthermore, it would be desirable to sliding slot 211 be set in the upside of grip sleeve, be then arranged on flexible core bar and stretch out sliding slot and can
Clamping structure is arranged between the front end of two flexible extended grip sleeves of core bar in the sliding pin 221 slided in sliding slot, so as to
When needing to clamp electrical body, two clamping jaws in left and right, which can connect, to be circularized.
In order to drive clamping jaw to act, we can be arranged in base shaft an actuating sleeve 3 and with actuating sleeve rotation connection
Connection unit 4, and a drive rod 5 is connected between the end that the sliding pin in the left side of connection unit and left side stretches out sliding slot,
A drive rod is connected between the end that sliding slot is stretched out on the right side of connection unit and the sliding pin on right side.In this way, when we make
When actuating sleeve is located at the position of readiness on rear side of base shaft together with connection unit, the front end of two clamping jaws in left and right is separated from each other and forms one
A opening, at this point, under the action of torsional spring, the spacer pin for the base shaft front end that reclines on the outside of the grip sleeve of two clamping jaws, to locate
In open configuration, the electrical body for needing to clamp can enter in the opening of two clamping jaws；When actuating sleeve together with connection unit forward
When being moved to the link position for being located at and on front side of base shaft and connecting the end of two flexible core bars, on the one hand drive rod makes telescopic core
Bar stretches out the front end of grip sleeve, so that two clamping jaws in left and right is turned to the inside and close to each other, at this time left and right two
The grip sleeve of clamping jaw is located in the same circular arc.The end of two flexible core bars is connected with each other by clamping structure, left and right two
A clamping jaw connects into circular ring shape, and two clamping jaws are in connection status at this time, and the electrical body clamped is needed then to be centered around
In two clamping jaws；When actuating sleeve is moved backward together with connection unit, since the front end of two flexible core bars at this time is connected with each other
It is arc-shaped together, therefore the rear side for being driven the flexible core bar of bar pulling can turn to the inside and close to each other, phase
Ying Di, flexible core bar drive grip sleeve to turn to the inside to clamp electrical body, at this point, flexible core bar then retracts grip sleeve
Interior, clamping jaw at this time is in clamp position.
It is understood that we can make to connect into circular arc by rationally designing the radius of grip sleeve, length equidimension
Two clamping jaws of shape have enough diameters, to ensure to need the electrical body clamped can be located in the circular arc that clamping jaw surrounds, and
Flexible core bar has enough strokes in grip sleeve, it is ensured that the clamping jaw in aid state can be formed enough electrical body
Chucking power.
When to ensure actuating sleeve Forward, left and right clamping jaw can reliably turn to the inside and surround arc-shaped, we can press from both sides
It holds and a wireline reel is set at rear end in casing, a positioning disc spring is set on wireline reel, position the inner end connection of disc spring
On wireline reel, the outer end for positioning disc spring is connected with the rear end of flexible core bar.
For the ease of the back-and-forth motion of actuating sleeve, as shown in Figure 4, Figure 5, spiral can be arranged on actuating sleeve inner sidewall in we
Slot 31, correspondingly, radially the guide pin 12 in helicla flute is protruded into setting in base shaft, so that base shaft be made to be formed with actuating sleeve
It is threadedly coupled.In this way, when our rotate drivings set when, can moving axially back and forth along base shaft, and then drive with actuating sleeve turn
The connection unit of dynamic connection is moved forward and backward.
In addition, we can also connect a transition lantern ring 6 in the outside screw of actuating sleeve, setting one turns in connection unit
Dynamic cavity 41, the inner sidewall for rotating cavity is interior concave spherical surface, and the lateral wall of transition lantern ring is the evagination fitted in rotation cavity
Spherical surface connects so that transition lantern ring and connection unit be made to form ball.Prolong along the longitudinal direction in addition, need to be arranged at the center of connection unit
The insertion hole 42 for stretching and penetrating through rotation cavity, the centre of sphere for rotating cavity should be located on the axis in insertion hole, in this way, base shaft can run through
It is inserted into hole.
Transition lantern ring connected to it can be pushed to rotate together when our rotate drivings set, and along the axial direction of base shaft
It is moved forward and backward, then connection unit is pushed to be moved forward and backward, formed relatively rotate between transition lantern ring and connection unit at this time.
In order to facilitate the installation of transition lantern ring, as shown in figs. 4 and 6, it would be desirable to be arranged on the rear end face of connection unit
One fitting groove 43, fitting groove tool is there are two the length side wall 431 being parallel to each other and is connected between two length side walls
Width sidewall 432, so that the cross section of fitting groove be made to be rectangle.The center line of fitting groove should pass through the center of rotation cavity,
The distance between two length side walls should be greater than the height of transition lantern ring, and fitting groove extends internally until width sidewall and rotation are empty
The inner sidewall of chamber is tangent.That is, the depth of fitting groove should reach at the center of rotation cavity.Certainly, width sidewall can also
The cylindrical surface of indent is made, and the radius of width sidewall is identical as the rotation radius of cavity.
When assembly, transition lantern ring first can be rotated 90 degree by us, and the axis of the axis and connection unit that make transition lantern ring hangs down
Directly, at this point, can put transition lantern ring in fitting groove into.When transition lantern ring moves inwardly into center and rotates the center weight of cavity
When conjunction, the lateral surface of transition lantern ring be bonded with rotation cavity, transition lantern ring can be rotated 90 degree at this time, thus make transition lantern ring with
The axis of connection unit is overlapped, and transition lantern ring can be made to be reliably positioned in rotation cavity, can will then be placed with transition sleeve
The connection unit of ring is threaded on actuating sleeve.
In addition, also the straight trough axially extended can be arranged positioned at the front side of helicla flute on the inner sidewall of actuating sleeve in we
32, the rear end of straight trough is connected with the front end of helicla flute.In this way, when we need to move forward actuating sleeve, it can be first along axial direction
Straight line fast moves, and the guide pin in base shaft slides in straight trough at this time, to be conducive to improve working efficiency when clamping.
When equal guide pins reach the front end of helicla flute, then actuating sleeve is rotated, guide pin can enter in helicla flute at this time, to make
Actuating sleeve can slowly move forward.When screw-casing be moved to for when, by helicla flute self-locking effect, it can be achieved that clamping jaw aid shape
State it is reliable self-locking, avoid the voluntarily loosening of clamping jaw.
In order to ensure linear movement of the connection unit in base shaft, leading of axially extending can be also arranged in we in base shaft
To straight trough 13, while the anti-rotation pin being radially penetrated into guiding straight trough is set on the side wall that inserts in the hole of connection unit front end
421, it is relatively rotated to avoid between connection unit and base shaft.
Further, as shown in Figure 1, clamping structure of the invention includes that the flexible core bar front end in left side is arranged in outward
It is bent into L-shaped hook 222, the flexible core bar front end that is arranged in right side is bent into L-shaped hook, the drive rod in left side inwardly
Front end setting rectangle regulating tank 51, slideably detent is in regulating tank for the sliding pin on the flexible core bar in left side, right side
The front end of drive rod be rotatablely connected with corresponding sliding pin, the front end of the drive rod on right side is rotated with corresponding sliding pin to be connected
It connects.In addition, the driving pole length in left side is greater than the driving pole length on right side, to keep the left side clamping jaw in open configuration outside
The angle that side is opened is less than the angle that right side clamping jaw is opened outward.Certainly, corresponding locking need to be also arranged in we in base shaft
There is a lockup state and a unlocked state can limit when lockable mechanism is in lockup state for mechanism, the lockable mechanism
Grip sleeve turns to the inside, so that it is guaranteed that clamping jaw can be positioned on connection status.When lockable mechanism is in the unlocked state, clamping
Casing can be freely rotated inwardly, to make clamping jaw that can be converted to aid state from connection status.
Specifically, as shown in Figure 1, Figure 7 shows, lockable mechanism includes being movably disposed in base shaft to be located at the clamping of left and right two
Two bars 14 on the inside of casing, when clamping jaw is in connection status, recline the upper of left side bar on the inside of the grip sleeve in left side
It holds, the upper end for the right side bar that reclines on the inside of the grip sleeve on right side.It is arranged one in addition, being located on rear side of bar on the downside of base shaft
The middle part of fulcrum bearing 15 with rotation axis, a poke rod 16 is rotatably connected in the rotation axis of fulcrum bearing.The front end of poke rod
Two compression bars 17 are connected, two compression bars and poke rod connect into Y shape, and the front end of two compression bars is cut with scissors with the lower end of two bars respectively
It connects, torsional spring is set in rotation axis, which drives poke rod rotation, to make bar move up by compression bar, to stop to press from both sides
It holds casing to turn to the inside, lockable mechanism is in lockup state at this time.When we press the rear end of poke rod, pressure can be passed through
Bar moves down bar, and grip sleeve can turn to the inside, and lockable mechanism is in the unlocked state at this time.
When clamping jaw is in open configuration, the sliding pin in left side is located at the rear end of regulating tank, since the drive rod in left side is long
Degree is greater than the driving pole length on right side, and therefore, the angle that left side clamping jaw is opened outward is less than what right side clamping jaw was opened outward
Angle.In particular, we can by the torsional spring on clamping jaw at left and right sides of reasonable design and position the preload elastic force of disc spring with
And the parameters such as coefficient of elasticity, when so that needing to clamp electrical body, actuating sleeve can be first moved forward, actuating sleeve is then rotated further by, from
And pushing drive rod to move forward by connection unit, left side drive rod makes the grip sleeve in the clamping jaw in left side inwardly at this time
Rotation, and then keep opposite due to the positioning biggish preload elastic force of disc spring between left side grip sleeve and the flexible core bar of inside
It is fixed.At the same time, right side drive rod makes the flexible core bar on right side first stretch out grip sleeve, and the grip sleeve on right side is then due to turning round
The biggish preload elastic force of spring is remain stationary.When we continue to move forward actuating sleeve, the grip sleeve in left side turns to the inside in place,
And be locked up mechanism and be locked at connection status, then its internal flexible core bar overcomes the elastic force of positioning disc spring and forward extends out,
The hook of telescopic core boom end moves in place in advance.At the same time, the flexible core bar inside the grip sleeve on right side forward extends out
In place, then, grip sleeve overcomes the elastic force of torsional spring together with internal flexible core bar and turns to the inside in place, and is locked up machine
Structure is locked at connection status.The hook of right side telescopic core boom end convex is overlapped on the hook of left side clamping jaw, to realize a left side
Connection between the flexible core bar in the right side.Then actuating sleeve is rotated backward, thus drive drive rod to move backward by connection unit, it is right
The drive rod of side forms a pulling force to telescopic core bar, to make the hook of the flexible core bar in left and right, tightly hooking is together.This
Outside, which forms a torque to the telescopic core bar on right side, and flexible core bar turns to the inside by center of rotation of hook, after
And the grip sleeve on right side is driven to turn to the inside, the rear side for the core bar that stretches at this time retracts in grip sleeve.And left side is flexible
Sliding pin on core bar first slides in regulating tank on drive rod, and therefore, drive rod does not work to the clamping jaw in left side, that is,
