Summary of the invention
Purpose of the present invention is the shortcoming that overcomes prior art, provides a kind of simple and reasonable, can regulate the guide pin bushing in gap simultaneously.
For solving the problems of the technologies described above, concrete technological scheme of the present invention is as follows:
A kind of adjustable clearance guide pin bushing is characterized in that: comprise a fixed block, described fixed block integral body is sleeve-shaped, is divided into stretched part and flange part; Described stretched partly has the groove that connects tube wall; Described groove is being circumference uniform distribution at described fixed block; Have the adjustment hole that communicates with described groove on the described fixed block end face;
Also comprise movable guide bush, described movable guide bush integral body is sector structure, is divided into flange part and stretched part, and described stretched part external arc surface has the wedge-shaped impression with described fixed block groove Corresponding matching; Described movable guide bush flange part end face has the U-shaped groove that is complementary with described fixed block adjustment hole;
Described movable guide bush embeds in the described fixed block; The groove of described fixed block is corresponding with the position of the wedge-shaped impression of described movable guide bush; And described U-shaped groove is corresponding with described adjustment hole position;
Also comprise the wedge shape regulating block, the cavity shape that the shape of described wedge shape regulating block and described fixed block groove and movable guide bush wedge-shaped impression consist of is similar; Described wedge shape regulating block embeds in fixed block groove and the movable guide bush wedge-shaped impression; Described wedge shape regulating block end face has tapped hole; Described tapped hole and the corresponding coupling of described fixed block adjustment hole;
Also comprise adjusting screw, described adjusting screw is passed U-shaped groove, fixed block adjustment hole and the regulating block tapped hole of described movable guide bush, and the three is connected.
Further, to be the groove number of circumference uniform distribution be 3 ~ 6 to described fixed block; Described movable guide bush is consistent with described groove number with the regulating block number.
Further, also comprise the guide pin bushing empiecement, described guide pin bushing empiecement is circular arc, is nested in the described movable guide bush bore circular arc groove, and adopts sunk screw and described movable guide bush fastening; Also be provided with annular oil storage tank on the described guide pin bushing empiecement endoporus.
The invention has the advantages that: the present invention is simple and reasonable, gap that can the manual tune guide pin bushing, thus improve the guiding accuracy of guide pin bushing, have stronger practicability.
