For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that
A kind of combined type leading screw, comprises the several osculums having and spaced several sections of outside threads on the body of rod of cavity and the outer wall of the body of rod and body of rod outer wall are communicated with cavity; The described body of rod comprises the left body of rod of coupling mutually and the right body of rod; The through left body of rod of described cavity and the right body of rod; Described left body of rod right-hand member is provided with shrinkage pool, and has the positioning pin hole of through shrinkage pool along the radial direction of the left body of rod, is provided with screw in positioning pin hole upper end; The connection shaft part that described right body of rod left end is provided with stretches in shrinkage pool, is fixed, and be provided with plug screw by locating stud in screw.
Further, described plug screw is the locking plug screw with full external thread structure.
Further, the length of described plug screw is less than the degree of depth of screw.
Further, the outside thread on the described body of rod is all equidistantly arranged.
Further, between every two sections of described outside threads, be all at least provided with four osculums, and osculum uniform setting centered by body of rod axis.
Further, the described body of rod two free end is equipped with the location shaft shoulder.
The advantage that the utility model has and good effect are: the outside thread equi-spaced apart of this leading screw is arranged, and outside thread can accept by the inner cooling liquid cooling action flow through of the body of rod, efficiently radiates heat, ensure that leading screw normally works, long service life, and the body of rod is left and right two-part fabricated structure, be easy to processing and transport, cost of production is low.

Embodiment
It should be noted that, in not afoul situation, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
A kind of combined type leading screw, as depicted in figs. 1 and 2, comprises the several osculums 4 having and spaced several sections of outside threads 3 on the body of rod 2 of cavity 1 and the outer wall of the body of rod 2 and the body of rod 2 outer wall are communicated with cavity 1; The described body of rod 2 comprises the left body of rod 5 and the right body of rod 6 of coupling mutually; The through left body of rod 5 of described cavity 1 and the right body of rod 6; As shown in Figure 3, the described left body of rod 5 right-hand member is provided with shrinkage pool 7, and has the positioning pin hole 8 of through shrinkage pool 7 along the radial direction of the left body of rod 5, is provided with screw 9 in positioning pin hole 8 upper end; The connection shaft part 13 that the described right body of rod 6 left end is provided with stretches in shrinkage pool 7, is fixed, and be provided with plug screw 11 by locating stud 10 in screw 9.
It should be noted that, positioning pin hole 8 is blind hole, and one end of its opening is screw 9, effectively prevent the locating stud 10 connecting the left body of rod 5 and the right body of rod 6 and comes off.
Wherein, described plug screw 11 is for having the locking plug screw of full external thread structure.After the connection shaft part 13 of the right body of rod 6 stretches into shrinkage pool 7, then located by locating stud 10, in order to avoid locating stud comes off, the top of locating stud is fixed a plug screw 11.
Wherein, the length of described plug screw 11 is less than the degree of depth of screw 9.This leading screw after having assembled, should ensure not conflict with locating stud 10 top in plug screw 11 bottom, and like this, plug screw 11 is not by the active force of locating stud 10, and permanent use can not get loose, and ensures that locating stud 10 can not come off from positioning pin hole 8.In addition, when installing plug screw 11, the screw thread of plug screw 11 can be smeared screw thread glue locking.
Wherein, the outside thread 3 on the described body of rod 2 is all equidistantly arranged.
Wherein, between every two sections of described outside threads 3, be all at least provided with four osculums 4, and osculum 4 uniform setting centered by the body of rod 2 axis, the cooling liquid flowed out in osculum 4 is evenly trickled down on each outside thread 3, good cooling results.
Wherein, the described body of rod 2 liang of free ends are equipped with the location shaft shoulder 12, ensure firm being arranged on bearing in leading screw two ends.
The leading screw that the utility model provides, its outside thread 3 equi-spaced apart is arranged, and outside thread 3 can accept the cooling liquid cooling action flow through by the body of rod 2 inside, efficiently radiates heat, ensures that leading screw normally works, long service life, and the body of rod 2 is left and right two-part fabricated structure, by connecting the firm connection of shaft part 13, be easy to processing and transport, cost of production is low.
