The external diameter of the cylinder chamber internal diameter of described insulating sleeve 7, the cylinder chamber internal diameter of described branch sleeve 9 and described diversion rod 5 is all consistent, or at least ensures to make the external diameter of described diversion rod 5 be less than the cylinder chamber internal diameter of less in described insulating sleeve 7 chamber internal diameters, branch sleeve 9 chamber internal diameters.
Heavy chamber can be also set in the lower end, cylinder chamber of described insulating sleeve 7.When described pressed slider 4 compresses wire clamp pressing plate, the lower end of described diversion rod 5 extends to described insulating sleeve 7 chamber lower ends and sinks in chamber.Described handle 8 upper end arranges column-shaped boss and is connected with described diversion rod 5 lower end.The external diameter of described handle 8 column-shaped boss is less than described insulating sleeve 7 chamber lower ends and sinks the internal diameter in chamber.Like this, diversion rod 5 is all in insulating sleeve 7 in the clamp state, ensure that safety in utilization.
When applying, clamping jaw is the notch formed between described upper frid lower surface and described pressed slider upper surface, so when moving to top on initial position and described diversion rod, need guarantee that the vertical interval between upper frid lower surface and pressed slider upper surface is less than the vertical thickness of wire clamp pressing plate, and now described holddown spring must be in compressive state.It, by the upright position of the relatively described lower frid of described branch sleeve, can set the thrust of described holddown spring, ensure clamping effect of the present invention.
Because in the gripper clamp notch portion that upper frid 1 is formed with pressed slider 4, the real position contacted with wire clamp pressing plate is right side slot-open-section, so the maximization in order to ensure clamping force vertical stress component, the upper end of described diversion rod 5 is made to be connected to the right-hand part center of the lower surface of described pressed slider 4.
As shown in Figure 4 and Figure 5, described upper frid 1 also comprises contact pressing plate 11 and multiple lead 12 (the two is metal material and makes).For realizing upper frid 1 and the assembly connection contacting pressing plate 11 and lead 12, uniformly on frid 1 on described through hole that multiple Vertical dimension extends being set and the lower end of each through hole is set to counterbore.Described lead 12 one_to_one corresponding is assemblied in the through hole on described upper frid 1, and the external diameter of lead 12 is consistent with through-hole diameter on upper frid 1.The upper and lower side of described lead 12 all extends through hole on described upper frid 1.Radial pin-and-hole is set in the upper end of described lead 12, in pin-and-hole, installs pin carry out support guide post 12 and make it be fixed on frid 1, unlikely vertical landing.Certainly can also arrange radial flange (can be annular flange or annular interrupted flange continuously) in the upper end of described lead 12, the upper surface of the upper frid 1 of lower surface contact of flange, comes support guide post 12 and upper frid 1.Described lead 12 is nested with spring respectively, the upper end of spring is placed in the counterbore of described upper frid 1 through hole lower end all the time.In the lower end of lead 12, external screw thread is set.
As shown in Figure 4 and Figure 5, involved contact pressing plate 11 form is different.
Contacting pressing plate 11 described in Fig. 4 is an entirety, its lower surface is concavo-convex alternate wavy, and formed wavy raised line and groove bearing of trend be view front and back to, the lower surface of raised line is plane, and the bottom surface of groove can be plane (as diagram).Preferably make the left and right of raised line be less than the left and right of groove to width to width, move when realizing pinching action like this on pressed slider 4, the raised line part only contacting pressing plate 11 lower surface contacts with wire clamp pressing plate upper surface.As for the upper surface of described contact pressing plate 11, it can be plane, also can as shown in Figure 4, in corresponding with its lower surface wavy.On corresponding described on described contact pressing plate 11, on frid 1, through hole arranges vertically extending projection, projection is arranged the lower end threaded engagement of tapped blind hole and described lead 12, and the lower end of described spring is placed on the outer wall of corresponding projection respectively.As shown in Figure 4, projection is arranged in the groove of contact pressing plate 11 upper surface, and the raised line upper surface of upper surface is plane.
In Fig. 5, described contact pressing plate 11 is Split type structure, and it is made up of multiple separate stripe board, the bearing of trend of each stripe board consistent and be view direction front and back to.The lower surface of each stripe board is plane, and upper surface is as described above the same, arranges projection equally and connects with corresponding lead 12 and spring.
Relative to the simple structure described upper frid 1 lower surface being set to plane shown in Fig. 1 to Fig. 3, the outstanding advantages that alternate contact plane structure (Fig. 4, for the alternate contact action of contact pressing plate 11 lower surface raised line is in wire clamp pressing plate, forms the alternate contact action of each stripe board lower surface difference of contact pressing plate 11 in wire clamp pressing plate in Fig. 5) in Fig. 4, Fig. 5 has is analyzed as follows:
Upper the stressed of frid 1 is analyzed, although upper frid 1 is through multiple bolt in diagram, be connected between side plate 3 by its front and back sides, but still can be regarded as cantilever beam structure to a certain extent, pressed slider 4 gives it with upwards active force by wire clamp pressing plate, and these upwards the cantilever action effect that formed upper frid 1 of active force right-to-left (in diagram) is inconsistent, cause the deflection of frid 1 right-to-left inconsistent successively, so upper frid 1 free end is easily bent upwards in Long-Time Service situation, accelerate the speed that its clamping reliability lost efficacy, conventional method increases upper frid 1 thickness, improve its bending resistance, but the weight of whole device can be increased.
Need to polish to the contact-making surface of wire clamp pressing plate in addition before this device of use, so the flatness guaranteeing the whole plane of polishing must be needed, because during clamping wire clamp pressing plate with upper frid 1 contact plane for firmly to contact, if flatness tolerance is larger, the irregular contact gap of easy generation, not only affect clamping effect, and the stress making the cantilever action of above-mentioned active force affect formation local excessive is concentrated, and more easily causes frid 1 to be out of shape.
After the contact pressing plate 11 increasing structure as shown in Figure 4, Figure 5 at upper frid 1 and lead 12, wire clamp pressing plate indirectly-acting is in upper frid 1.Be subject to upwards after active force at contact pressing plate 11, whole contact pressing plate 11 moves, lead 12 can along through hole upwards vertically movement on upper frid 1, upper frid 1 is compressed with the spring contacted between pressing plate 11, spring acts on upwards upper frid 1 and contact pressing plate 11 respectively, downward power, when the upper surface of pressing plate 11 to be contacted contacts the lower surface of upper frid 1, move on contact pressing plate 11 stops.Now, upper frid 1 with contact spring between pressing plate 11 and produce elastic acting force, ensure clamping effect, simultaneously due to the cushioning effect of spring, change the state that frid 1 is subject to right-to-left active force, active force is reduced upper frid 1 deformation effect, and namely spring absorbs the stress deformation of frid 1.Frid 1 service time in prolongation.Particularly when contacting pressing plate 11 shown in Fig. 4, can further by the distortion of contact pressing plate 11 self, overcome the deformation effect of active force to upper frid 1, even and if now the contact-making surface flatness of wire clamp pressing plate differs greatly, also stress raisers can not be there are at contact-making surface, because it is cancelled by the self-deformation contacting pressing plate 11, so clamping effect can be better.
For contacting pressing plate 11 and lead 12 structure shown in above-mentioned Fig. 4 with Fig. 5, it can be transplanted on pressed slider 4, increases the non-deformability of pressed slider 4, extends working time.But consider that being also subject to diversion rod 5 near pressed slider 4 free end acts on, think and realize the synchronous of upper frid 1 and pressed slider 4 useful life, pressed slider 4 upper end is only simple planar structure as shown in the FIG..
As shown in Figure 6 to 8, uniform on frid 1 on described multiple vertically extending tapped through hole is set, the post 13 that leads is equipped with in each tapped through hole, the upper end assembling insulation handwheel 14 of the described post 13 that leads, the lower surface of the described post 13 that leads is arranged file sword 131, indicator light 15 with shown post 13 conducting of leading is set in the center of described insulation handwheel 14, for the conducting relation of indicator light 15 with the post 13 that leads, it can be the relation of being rigidly connected, also can be just can make the two conducting after pressing indicator light 15 downwards, and make again the conducting relation of the two disconnect when secondary pressing indicator light 15.By this technical scheme, no longer need in use to polish to the contact-making surface of wire clamp pressing plate in advance, the substitute is and drive the post 13 that leads to rotate by rotating insulated handwheel 14, by the file sword 131 led on post 13 lower surface, the oxide skin on wire clamp pressing plate is removed, it is to be noted herein, when leading post 13 scale removal with the drive of insulation handwheel 14, after need guaranteeing to be rotated down certain all numbers, then reverse two weeks, oxide skin powder is discharged, and then be rotated down and proceed oxide skin Transformatin.Indicator light 15 is used for indicating the removing completeness situation of oxide skin, namely when indicator light 15 in certain time length can continuous illumination and just show when not glimmering oxide skin remove up to standard, so preferably make indicator light 15 take secondary to press the structure be connected with leading between post 13, namely first time pressing makes the two connect, second time pressing makes the two disconnect, to ensure the useful life of indicator light 15.
Except the technical characteristic described in specification, be the known technology of those skilled in the art.
