The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Figure 1 shows that the structural representation of thread cutter among the utility model embodiment.As shown in Figure 1, thread cutter comprises pedestal 1, the fixture 6 that slidably is arranged on the strip slip backstay 2 of stating on the pedestal 1 and is used for location strip slip backstay 2 among the utility model embodiment.
In conjunction with shown in Figure 1, when carrying out the shearing of tap line 4, at first slide strip slip backstay 2 to pedestal 1 on the distance of its right end face satisfy Len req, can measure by tape measure isometry instrument, also can measure by the yardstick groove that arranges take pedestal 1 its right end face as starting point at pedestal 1, the direction of arrow among the figure is the movable direction of strip slip backstay 2; Then by the fixing strip slip backstay 2 of fixture, realize the location; Then the end face of tap line 4 one ends is navigated on the strip slip backstay 2, pasting its right end face of pedestal 1 with cutting nippers and cutting off tap line 4, obtain the tap line 4 of Len req.
Thread cutter provided by the utility model comprises pedestal, the fixture that slidably is arranged on the strip slip backstay on the pedestal and is used for location strip slip backstay, locate the length of tap line by the slip of strip slip backstay on pedestal, realization is to the shearing of different length tap line, so that the sheared length of tap line is accurate, and the length of slip backstay location can realize the shearing of many same size specification tap lines, improved the efficient that tap line is sheared, in can carrying out, the processing of small lot.
Wherein, realize that the mode that strip slip backstay 2 slidably is arranged on the pedestal 1 has a variety of, select strip slip backstay 2 to be set on the pedestal 1 in the present embodiment, and in the side-walls over against pedestal 1 screwed hole 7 is set, the chute 8 that on the sidewall of pedestal 1, mates along the 2 glide direction settings of strip slip backstay and screwed hole 7 simultaneously.The screw 6 that cooperates with screwed hole 7, is realized the strip backstay 2 that slides slidably is arranged on the pedestal 1 by screwed hole 7 turn-knobs to chute 8.Simultaneously chute 8 is arranged on the sidewall of pedestal 1, can reduces the base area of pedestal 1, thereby reduce the occupation of land space of thread cutter.
On the other hand, can also locate strip slip backstay 2 by screw 6, and fixture can be selected screw 6.When needs slip strip slip backstay 2, unclamp screw 6; When needs location strip slip backstay 2, tighten screw 6, realize the location.
Behind the location that strip slip backstay 2 is realized tap line 4, for guaranteeing the precision of tap line 4 sheared lengths, preferably over against the bottom surface of strip slip backstay 2 several grooves 3 are set at pedestal 1, as shown in Figure 1, in the present embodiment be four, wherein, the direction of groove 3 is parallel to the glide direction of strip slip backstay 2, the aperture of groove 3 is slightly larger than the diameter of tap line 4, so that tap line 4 can not be distorted, thereby guarantees the accuracy rate of tap line 4 length.Be to increase versatility and the flexibility of thread cutter, the aperture of each groove 3 can be different, are respectively from top to bottom 2.0cm, 1.5cm, 1.2cm, 1.0cm such as the aperture of four grooves 3, realize the shearing to different-diameter specification tap line 4.
For preventing that tap line 4 arches upward because of stressed in the shear history, can the line pressing rod 5 parallel with strip slip backstay be set at pedestal 1 in the present embodiment, wherein, line pressing rod 5 slidably is arranged on the pedestal 1, tap line 4 sheared lengths are not simultaneously, adjust at any time the position of line pressing rod 5, the general centre position of selecting to be positioned at tap line 4 can better must compress tap line 4 and not arch upward.Preferred line pressing rod 5 the same with strip slip backstay 2 structures and with the annexation of pedestal 1 too, do not need to arrange separately the connector of line pressing rod 5 and pedestal 1, also simplified the structure of thread cutter in the time of raising device assembly versatility.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
