Novel screw mandrel die set
Technical field
The utility model relates to a kind of novel screw mandrel die set.
Background technique
Because the module assembling of screw mandrel requires very high for assembly technology, especially the parallelism of two guide rails and screw mandrel is difficult to ensure especially, method general at present beats the straightness accuracy of screw mandrel and guide rail, although the method precision is high but efficiency of assembling is low, output is little, and what thus use is few; Another kind method uses hand propulsion slide block, guide rail and screw mandrel are regulated automatically, be as the criterion with the smooth degree of feel, although the method assembling speed is fast, precision is low, screw mandrel and guide rail cannot be made to reach real parallel, make the steel ball of screw mandrel inside monolateral stressed, in load with after a period of time, worn steel ball can be made serious, produce gap, precision and noise all can obviously produce.
Summary of the invention
The utility model, in order to overcome above-mentioned deficiency, provides a kind of low to assembly technology requirement, and the novel screw mandrel die set that efficiency of assembling is high.
The technical solution of the utility model is as follows:
A kind of novel screw mandrel die set, comprise aluminium base, one end of described aluminium base is provided with supporting base, and the other end is provided with fixed base, and aluminium base is also provided with cover plate, ball screw is provided with in aluminium base, one end of described ball screw is connected with motor through fixed base, is also respectively equipped with guide rail, is provided with bearing in described supporting base in the both sides of ball screw, be provided with polished rod in bearing, the other end of ball screw is connected with polished rod by the first coupling; Described ball screw and two guide rails are parallel to each other.
Ball screw one end through fixed base is connected with motor by the second coupling.
Described ball screw is also provided with a worktable, and worktable passes from the both sides of cover plate, and worktable is positioned on two guide rails simultaneously, moves along guide rail.
The beneficial effects of the utility model are:
The utility model inserts one section of optical axis in the bearing of supporting base, connect with the first coupling between optical axis and screw mandrel, the effect of this first coupling absorbs in supporting base adjustment process and the decentraction of screw mandrel, assembly technology like this for supporting base requires greatly to reduce, and can also improve efficiency of assembling simultaneously.
In employing this kind of design, one end processing of screw mandrel can be removed, save processing cost, and according to the change of stroke, be free to cut away and divide screw mandrel and aluminium base, facilitate the change of stroke, in practical set, improve packaging efficiency and the smooth degree of product, also there is the advantage reducing noise.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is stereogram of the present utility model;
Fig. 2 is the utility model internal structure schematic diagram;
Fig. 3 is the enlarged view of local A in Fig. 2.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Novel screw mandrel die set as Figure 1-3, comprise aluminium base 1, one end of described aluminium base 1 is provided with supporting base 3, the other end is provided with fixed base 4, aluminium base 1 is also provided with cover plate 2, ball screw 5 is provided with in aluminium base 1, one end of described ball screw 5 is through fixed base 4, and be connected with motor by the second coupling, guide rail 6 is also respectively equipped with in the both sides of ball screw 5, bearing is provided with in described supporting base 3, polished rod 7 is provided with in bearing, the other end of ball screw 5 is connected with polished rod 7 by the first coupling 8, the effect of this first coupling absorbs in supporting base adjustment process and the decentraction of screw mandrel, assembly technology like this for supporting base requires greatly to reduce, efficiency of assembling can also be improved simultaneously.Described ball screw 5 and two guide rails 6 are parallel to each other, and ball screw 5 is also provided with a worktable 9, and worktable 9 passes from the both sides of cover plate 2, and the bottom of worktable 9 is positioned on the guide rail 6 of both sides simultaneously, and worktable can move along guide rail 6.
Above-mentioned is enlightenment according to the utility model, and by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
