Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete description, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on embodiments of the invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
A kind of turbine case cap-blocking press-loading centering device described in the present embodiment, as shown in Fig. 1~Fig. 6, including gland 1, pressure head 6, depression bar 2, pressed sleeve seat 7, described pressed sleeve seat 7 is directly connected with press.
Described pressed sleeve seat 7 is connected with gland 1 by the first quick-changing mechanism, described first quick-changing mechanism includes a latch 8 with handle or bracelet 9 and is arranged on pressed sleeve seat 7 and gland 1 slot 11 matched with described latch 8, and described pressed sleeve seat 7 is connected with gland 1 by described latch 8 and slot 11.Preferably, the part of described gland 1 is abutted by a flange face 17 in extending into described pressed sleeve seat 7.So, described pressed sleeve seat 7 can be fastenedly connected with gland 1 by the first quick-changing mechanism and flange face 17, and the requirement of precision can be met well.
Described gland 1 the latter half is axially a hollow structure 20, is provided with the second quick-changing mechanism in described hollow structure 20, and being provided with one between described second quick-changing mechanism and hollow structure can be along described hollow structure inwall pressure head 6 in axial sliding.Described second quick-changing mechanism includes a regulation screw 4, the screw 13 that described regulation screw 4 is arranged by described hollow structure 20 top is connected with described gland 1, described regulation screw 4 run through one be arranged at hollow structure in the axle center of axial spring 5, one end of described spring 5 is against the top of described hollow structure, and the other end is against on the end face of described pressure head 6;The top of described pressure head 6 extend between the inwall of described hollow structure 20 and described regulation screw 4.Described pressure head 6 includes a counterbore 14, and the maximum gauge of the bottom of described regulation screw 4 is less than the internal diameter of described counterbore 14.Described pressure head 6 can slide axially in described hollow structure, and described pressure head 6 coordinates for wide arc gap with gland 1.Described pressure head 6 uses spring steel material, the most easy to wear, and is not easy fracture.
In this preferred embodiment, described gland 1 the latter half is evenly equipped with four symmetrical two-by-two elongated slots 12 along marginal area circumference, is equipped with a depression bar 2 in each elongated slot 12, and described depression bar 2 uses a kind of material in spring steel, rustless steel to make.Described depression bar 2 coordinates with gland 1 small-gap suture, and during original state, described pressure head 6 end highlights below depression bar 2 end.Described depression bar 2 is fastened in described gland 1 by the 3rd quick-changing mechanism, the screw hole 15 matched with described and tight screw 3 that described 3rd quick-changing mechanism includes and tightly screw 3 and described gland 1 lower end side are arranged, described and tight screw 3 makes elongated slot 12 inwall that described gland 1 is close to by depression bar 2;Being arranged with locking nut 10 on the described and thread spindle of tight screw 4, the outer wall of described gland 1 is close in the inner side of described locking nut 10;Preferably, the lower end of described depression bar 2 is provided with the flange face 16 abutted with described gland 1 end face, so can ensure that below many depression bar flanges are highly consistent, thus ensure that multiple impression depth concordance.
During application the present embodiment, the work process of native system is as follows:
When carrying out pressing blanking cover operation, workpiece is positioned on workbench, now pressure head 6 end highlights below depression bar 2 end, pressure head 6 is directed at the discarded hole of turbine case, then starts press, along with press is the most down pressed, pressure head 6 arrives to turbine case, and up walks under the resistance of turbine case, compression spring 5 simultaneously, under the counteracting force of spring, pressure head carries out pre-pressing to blanking cover.Along with pressing under the continuation of press, pressure head 6 is by dead gland 1, now the end of depression bar 2 highlights the end of pressure head 6, prominent size can be regulated by regulation screw 4 according to actual needs, at present pressing together by after death pressure head 6 and depression bar 2, until blanking cover is pressed into ideal position, depression bar 2 can extrude pit on exhaust apertures edge simultaneously, after a turbine case presses blanking cover operation to complete, press tenth skill.
Controlling press to withdraw, now pressure head 6 stretches downwards under the counteracting force of spring 5, and progressively protrudes from described depression bar end, and after spring is fully relaxed, pressure head returns to original state, is ready for punching press next time.
When different parts are press-fited by needs, hold the handle on latch 8 or bracelet 9, extract latch 8, unload gland 1 main body, change gland 1 main body of another frock, insert latch 8, complete the quick-replaceable of frock gland 1.
When pressure head 6 occurs that breakage needs to change, unscrew described regulation screw 4, take off the pressure head 6 of breakage, replace with new pressure head 6 regulation screw 4 of again screwing on, it is achieved the quick-replaceable of pressure head 6.
When depression bar 2 abrasion needs to change, unclamp locking nut 10 and the tightest screw 3, pull up depression bar 2, change new depression bar 2, tighten and tight screw 3, locking nut 10, it is achieved the quick-replaceable of depression bar 2.
When needing turbine case is carried out multi-angle, many quantity is when press-fiting, and can arrange many depression bars 2 according to actual needs, to meet multi-angle and the demand of many impressions quantity.
The present invention is not limited to aforementioned embodiments, and those skilled in the art are under the enlightenment of the technology of the present invention marrow, it is also possible to make other changes, but as long as its function realized is same or similar with the present invention, all should belong to protection scope of the present invention.
