Below in conjunction with accompanying drawing, the utility model is described in detail.
Detailed description of the invention
As shown in Figure 1 and Figure 2, be respectively the front view after carbon slipper of the present utility model bonding clamping tool clamping carbon slipper and top view, the bonding clamping tool of this carbon slipper, for being clamped by the carbon bar on the bracket of carbon slipper and its, it comprises: for settling the base 1 of the bracket 2 of carbon slipper thereon; Be arranged at gripper shoe 7 above base 1 and in parallel; Be arranged on a pair connecting rod 6,12 for gripper shoe 7 and base 1 being linked together between gripper shoe 7 and base 1; Holding down assembly of the carbon bar 3 of carbon slipper is compressed via gripper shoe 7.
Concrete, as shown in Figure 1 and Figure 2, of the present utility model holding down assembly comprises: the screw rod 10 that its top is threaded with the middle part of gripper shoe 7; The hold-down head 4 for contacting with the upper surface of carbon bar 3 connected with the bottom of screw rod 10; Be arranged at the handle 9 being convenient to rotary screw 10 on screw rod 10 top; Preferably, handle 9 adopts wing nut.
Wherein, hold-down head 4 can adopt solid cylinder (not shown), and it can be fixedly connected with screw rod.When turning wing nut, screw rod 10 rotates and relative support plate 7 moves down or moves up, and makes hold-down head compress carbon bar downwards or upwards away from carbon bar, wherein, cylinder top can arrange taper platform.
Or hold-down head 4 of the present utility model can also adopt its center to arrange the cylinder (as shown in Figure 1) of shoulder hole.Accordingly, when hold-down head 4 center arranges shoulder hole (shoulder hole comprises aperture and is positioned at the macropore below aperture, the bigger small screw external diameter of hole diameter), the shoulder hole extending into hold-down head 4 bottom screw rod 10 is interior to be connected with hold-down head.Concrete, of the present utility model holding down assembly also comprises as lower member: be installed on screw rod 10 bottom and be placed in the attaching nut 11 in the shoulder hole of hold-down head 4, its appearance and size is greater than the diameter of the aperture of shoulder hole, is less than the diameter of the macropore of shoulder hole, is stuck in hold-down head 4 bottom of screw rod 10 to be connected with hold-down head by attaching nut 11; Be fixedly connected with (as welded) with screw rod 10 and be positioned at the stressed nut 5 above attaching nut 11, it coordinates with attaching nut 11, so that when turning screw rod 10, stressed nut 5 moves downward or upward along with screw rod 10, as, when moving down, stressed nut 5 is extruding hold-down head 4 downwards, makes hold-down head 4 compress carbon bar.
Wherein, gripper shoe 7 of the present utility model has the main body 71 of cuboid, offer the opening 74 extended along its width in the side of main body 71, offer the through hole 72 of the circle running through gripper shoe thickness at the opposite side of main body 71, screwed hole 73 is set at the center of main body 71.Wherein, a connecting rod 12 passes vertically through opening 74 place of main body 71, and another root connecting rod 6 passes vertically through through hole 72, and screw rod 10 is vertically fed through screwed hole 73.
Wherein, connecting rod 6 and connecting rod 12 are screw rod, and the bottom of screw rod is threaded with base 1.And preferred, the bracket 2 of carbon slipper is aluminium frame.
After the aluminium frame 2 of carbon slipper and carbon bar 3 surface are bondd by conducting resinl, adopt clamping tool of the present utility model both to be clamped, make both be close together, and then send into baking oven and carry out hot setting.
Clamping tool of the present utility model, the quick-clamping to carbon slipper and dismounting can be realized, wing nut on it is turning during gripper shoe pretension with hand, and then turn wing nut by torque spanner, realize the clamping to carbon slipper carbon bar and bracket of hold-down head and base, and, the torque magnitude controlling to apply wing nut by scale on torque spanner when fastening is to control the size of hold-down head to the clamping force of carbon slipper, thus the clamping force realizing putting on carbon slipper is even.
Clamping tool of the present utility model, its hold-down head faces carbon bar and contacts with carbon bar upper surface, and hold-down head is connected with screw rod 10, only need turn the clamping that screw rod just can realize carbon slipper, screw rod 10 is fed through the center of gripper shoe, namely, be middle reinforcing when turning screw rod 10, therefore, relative to existing technologies, its can ensure aluminium frame and carbon bar stressed evenly, namely to the clamping dynamics of carbon slipper evenly, the binding face of bracket and carbon bar can be made more even, thus both ensure that the connection electrical resistance of carbon slipper was even, in turn ensure that carbon bar more can not rupture when high-temperature baking, make the carbon slipper quality conformance produced good, percent defective is low, reduce production cost.And when dismantling clamping tool, can be completed fast by specific purpose tool, because base is connected by two screw rods with gripper shoe, when disassembled, slightly unscrew connecting rod 6 and connecting rod 12, gripper shoe can be made to rotate around the symmetry axis of connecting rod 6, make connecting rod 12 depart from gripper shoe from the opening part of gripper shoe, thus realize operating the rapid-assembling/disassembling of carbon slipper.
Although be explained in detail the utility model above; but the utility model is not limited thereto; those skilled in the art can modify according to principle of the present utility model; therefore, all various amendments carried out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
