Embodiment
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
Refer to shown in Fig. 1 to Fig. 3, graphic for the utility model one preferred embodiment, the utility model is a kind of ball screw of cooling type nut, comprises: a screw rod 1, it is strip structure, the outer edge surface of this screw rod 1 is provided with spiral helicine sliding channel 11; One nut 2, it has the first end face 23 and the second end face 24, this nut 2 is provided with the perforation 21 wearing for this screw rod 1, the inner edge surface of this perforation 21 is provided with the rolling groove 211 of this sliding channel 11 relatively, this nut 2 is provided with multiple cooling channels 22, and this first end face 23 and the second end face 24 are run through with this perforation 21 in this cooling channel 22; Multiple roll pieces 7, it is located between this sliding channel 11 and rolling groove 211; At least one return piece 6, be arranged at this nut 2, the return piece 6 that the present embodiment is lifted is two, and industry is called end plug type return piece, also can use the return piece of the alleged outer circulation type of industry or inner circulation type, therefore therefore why part no longer describes its structure in detail for located by prior art; Two end cap A, it is arranged at respectively this first end face 23 and the second end face 24, this end cap A suggestion is used screw to be fixed in this first end face 23 and the second end face 24, this end cap A is made up of a circuiting end caps 3 and shunting cover plate 4 respectively, this circuiting end caps 3 has through hole 31 and the convergence hole 34 wearing for this screw rod 1, be provided with the circular groove 32 of ring-type in the outside of this through hole 31, this circular groove 32 is communicated with this convergence hole 34, and this convergence hole 34 is in order to allow cooling liquid enter this circular groove 32 or to be exported by this circular groove 32; This shunting cover plate 4 confluxes 90 for loop configuration is covered on this circular groove 32 to form a cooling liquid, this shunting cover plate 4 is provided with multiple protuberances 42, this protuberance 42 is inserted in this cooling channel 22, this protuberance 42 be provided with one end and this cooling liquid conflux 90 be communicated with, tap hole 421 that the other end is communicated with this cooling channel 22; This end cap A is respectively equipped with a ring-like seal groove 35 in conflux 90 inner side and outside of this cooling liquid; The cooling liquid that multiple Sealings 5 are arranged at respectively two this end cap A conflux 90 inner side and outside, be arranged in sealing groove 35 in the present embodiment seal, but can also by double-material jet formation mode directly by the seal 6 respectively ejection formation in this cooling liquid conflux 90 inner side and outside, and the seal 5 is between the end face and the first end face 23 and the second end face 24 of this end cap A, in order to seal the gap between this end cap A and this first end face 23 and the second end face 24, to avoid cooling liquid excessive.
