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 illustrating the utility model, but can not be used for limiting scope of the present utility model.
Fig. 1 is the structural representation of the controlled chasing bar of the degree of depth of the utility model embodiment.
As shown in Figure 1, the controlled chasing bar of a kind of degree of depth of the present utility model, comprising: whirligig 1, thread tapping body 2, workbench 3 and stopping means 4.
Whirligig 1, its link arranging by lower end 11 is connected with thread tapping body 2, for driving thread tapping body 2 rotation limits, limit to move down, preferably, link 11 with thread tapping body 2 for being threaded.Whirligig 1 two ends are provided with slide block 12, and this slide block 12 is with support slide rail 7 for being slidably connected, and in the utility model, the distance that whirligig 1 moves down by slide block 12 is a steady state value.
Thread tapping body 2, be positioned at workbench 3 directly over, for the workpiece being positioned on workbench 3 is carried out to tapping.
Workbench 3, by stage clip 5 with support that polished rod 6 is movable to be connected, for carrying the workpiece of wanted tapping.When whirligig 1 drives thread tapping body 2 to move down the workpiece on workbench 3 is carried out to tapping, workbench 3 can slowly move down, until reach stopping means 4, because the distance that whirligig 1 moves down is constant, the distance that can move down by workbench 3 decides the tapping depth of workpiece.
Stopping means 4, be positioned at workbench 3 under, for limiting the distance that moves down of workbench 3, limit the degree of depth of work-piece tapping.
Fig. 2 is the structural representation of the stopping means of the utility model embodiment; Fig. 3 is the structural representation of the expansion link of the utility model embodiment.
As shown in Figures 2 and 3, stopping means 4 comprises pedestal 41, expansion link 42 and adjusting rod 43.By adjusting rod 43, insert and be arranged in the locating hole 421 on expansion link 42, expansion link 42 is locked on pedestal 41.On expansion link 42, be furnished with several locating holes 421, adjusting rod 43 inserts different locating holes 421, can realize the length that expansion link 42 stretches out, and then has changed the distance that the restriction workbench 3 of stopping means 4 moves down.
In embodiment of the present utility model, the edge of expansion link 42 is provided with scale 422, and the extension elongation that makes to adjust expansion link 42 is more accurate.
The course of work: after workpiece being positioned on workbench 3, in regulation limiting device 4, expansion link 42 is apart from the distance (the whirligig 1 fixing difference in height that moves down stroke and workbench deducts the depth value that workpiece is wanted tapping again) of workbench 3 bottoms, then by adjusting rod 43, expansion link 42 is locked, finally opening whirligig 1 can the required tapping depth of tapping workpiece.
As mentioned above, the controlled chasing bar of a kind of degree of depth of the present utility model has additional stopping means, can limit the distance that workbench moves down, to realize the control to the work-piece tapping degree of depth; In addition, on stopping means, be provided with rule, can accurately set the tapping depth value of workpiece.The controlled chasing bar of the degree of depth of the present utility model has advantages of that tapping depth is controlled and tapping depth control accuracy is high.
Below be only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
