Abstract
The utility model discloses a kind of positioning tools of screw-rolling machine, including support plate (1), the support plate (1) is just upper to prevent being fixedly connected with sleeve (101), sleeve (101) edge is aligned with support plate (1) edge, and the aperture lower surface in the middle part of sleeve (101) and support plate (1) upper plane are tangent.To solve the problems, such as that the prior art is low to the length machining accuracy of the conical surface, abnormal shape or step noodles part.
Description
Technical field
The utility model relates to field of machining more particularly to a kind of positioning tools of screw-rolling machine.
Background technique
In the prior art the processing of the conical surface, abnormal shape or step surface is needed to control the length f far from idler wheel end to machined surface,
Processing part is used close to the end face of idler wheel one end and is fixed on the supporting plate by the method that the prior art uses end face positioning
Limited block comes locating element horizontal position, uses the upright position for the support plate locating element being located at below processing part.For
The method of part horizontal position positioning can be found in Fig. 1, the former tooling limited block 102 ' of 1 ' upper right quarter of Central Plains tooling supporting block with
Former tooling supporting block 1 ' is fixedly connected, and part is pushed against former tooling limited block close to the end face of former tooling limited block 102 ' when processing
102 ', control can be obtained according to part length L and distance d to the distance d at 3 step of idler wheel by adjusting former tooling limited block 102 '
Length f=L-D.But this processing method has a problem that, due to being thermally expanded, the effect of idler wheel extruding force, above-mentioned distance
D can become larger in process, and part control size f required precision is higher, and the above method is unable to satisfy machining accuracy at all
It is required that.
Summary of the invention
Technical problem to be solved by the utility model is: a kind of positioning tool of screw-rolling machine is provided, to solve the prior art
The problem low to the length machining accuracy of the conical surface, abnormal shape or step noodles part.
The technical solution of the utility model is: a kind of positioning tool of screw-rolling machine, including support plate, the support plate just on
Anti- to be fixedly connected with sleeve, sleeve edges are aligned with support plate edge, the aperture lower surface in the middle part of sleeve and support plate upper plane
It is tangent.
Further, the positioning tool of the screw-rolling machine further includes pedestal, and pedestal is equipped with sliding slot, support plate lower width
Match with sliding slot, track length is greater than support plate length, and support plate lower slide is mounted in sliding slot.
Further, the pedestal further includes that at least 1 pair of locking hole and fastening bolt, locking hole is arranged in base side
Portion is directed toward track length vertical direction, and the internal screw thread that setting matches with fastening bolt screw thread in locking hole, fastening bolt can
Enter sliding slot by locking hole.
Further, upper surface parallel with sliding slot on the pedestal is equipped with graduated scale.
The beneficial effects of the utility model are:
Compared with prior art, the utility model by using sleeve part far from idler wheel limit, cancel limited block,
Avoid the influence of thermal expansion and idler wheel extruding force to part control size.The utility model structure is simple, easy to use, especially suitable
Share the processing in screw-rolling machine to the conical surface, abnormal shape or step surface.
Detailed description of the invention
Fig. 1 is used the structural schematic diagram of tooling by the utility model background technique；
Fig. 2 is the utility model side view；
Fig. 3 is the utility model top view；
Fig. 4 is the cross-sectional view of the horizontal cross-section in the middle part of the utility model；
In figure: 1 support plate, 1 ' former tooling supporting block, 101 sleeves, 102 ' former tooling limited blocks, 103 ' former tooling supports
Bar, 2 parts, 3 idler wheels, 4 pedestals, 401 installation bolts, 402 fastening bolts, 403 locking holes, 404 sliding slots, 5 graduated scales.
Specific embodiment
With reference to the accompanying drawing and utility model is described further in specific embodiment:
Referring to figs. 1 to Fig. 4, a kind of positioning tool of screw-rolling machine, including support plate 1,1 support plate 1 of support plate just on
Anti- welded sleeve 101,101 edge of sleeve are aligned with 1 edge of support plate, on the aperture lower surface and support plate 1 at 101 middle part of sleeve
Facial planes is tangent.Improved tooling has cancelled former tooling limited block 102 ' and former tooling support rod 103 ', directly uses sleeve 101
It is mobile to carry out limit feature, since idler wheel always has the tendency that dragging part toward idler wheel direction in rolled thread machining process, with this
Want sleeve 101 can limit feature it is not mobile toward 3 direction of idler wheel, it is ensured that part control length f is constant, so as to avoid heat
Expansion and idler wheel 3 squeeze the influence to part control length machining accuracy.
Further, the positioning tool of the screw-rolling machine further includes pedestal 4, and pedestal 4 is equipped with sliding slot 404, under support plate 1
Portion's width matches with sliding slot 404, and 404 length of sliding slot is greater than 1 length of support plate, and 1 lower slide of support plate is mounted on sliding slot 404
It is interior.By the way that by support plate 1, movement can be adjusted for different parts control length in sliding slot 4, so that tooling is more
Flexibly, it does not need to do a set of tooling for each part.
Further, the pedestal 4 further includes that at least 1 pair of locking hole 403 and fastening bolt 402, the setting of locking hole 403 exist
404 length vertical direction of sliding slot is directed toward in the middle part of 4 side of pedestal, setting matches with 402 screw thread of fastening bolt in locking hole 403
Internal screw thread, fastening bolt 402 can enter sliding slot 404 by locking hole 403.Support plate 1 can be limited by fastening bolt 402
404 is mobile in sliding slot, so that the movement of support plate 1 be avoided to impact part processing precision.
Further, upper surface parallel with sliding slot 404 on the pedestal 4 is equipped with graduated scale 5.It can be intuitive by graduated scale
See and adjust part control length.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the protection scope of the utility model.
