Wherein: 1, base; 2, the first module; 20, the first groove; 3, the second module; 30, the second groove; 31, guide-track groove; 4, top-pushing mechanism; 40, push rod; 41, push rod bearing; 42, first connecting rod; 43, the first Connection Block; 44, the second Connection Block; 45, second connecting rod; 46, hand-held pole; 5, guide rail.
The specific embodiment
as depicted in figs. 1 and 2, the copying fixture that the present embodiment provides, it is specifically for fixing computer rotation shaft, its structure comprises horizontally disposed base 1, along the length direction of base 1, extend and be fixed on the first module 2 on base 1, with the first module 2, parallel and arrange and can move along base 1 width the second module 3 of setting, and drive the top-pushing mechanism 4 that the second module 3 moves horizontally along the width of base 1, the second module 3 can be spliced mutually with the first module 2, in the first module 2, from the end face with the second module 3 splicings, cave inward and form the first groove 20, the second module 3 caves inward and forms the second groove 30 from the end face with the first module 2 splicings, and the first groove 20 is spliced to form the die cavity identical with the rotating shaft profile with the second groove 30, rotating shaft can stably be arranged in die cavity.
in this example, above-mentioned top-pushing mechanism 4 comprises along width one end of base 1 and is connected to two push rods 40 on the second module 3, be fixedly installed on the push rod bearing 41 that supports respectively two push rods 40 on base 1, the first connecting rod 42 that rotates and be connected with two push rod 40 the other end respectively, the first Connection Block 43 that is rotationally connected with the end of two first connecting rods 42 respectively, with two the first Connection Blocks 43, be rotationally connected and be fixed on the second Connection Block 44 on base 1 respectively, and rotate respectively the hand-held pole 46 that two second connecting rods 45 being arranged on the first Connection Block 43 and both ends are connected with the second connecting rod 45 that is positioned at both sides, push rod 40 can being located on push rod bearing 41 along himself length direction activity.
Further, two push rods 40 are uniformly distributed along the length direction of the second module 3, and an end of push rod 40 is fixedly connected with the second module 3; The two ends of hand-held pole 46 are welded on respectively on two second connecting rods 45.
In addition, in this example, on base 1, be provided with two guide rails 5 that parallel setting that extend along its width, in the bottom of the second module 3, be respectively equipped with the guide-track groove 31 that matches with two guide rails 5 simultaneously.Conflicting on the first module 2 in one end of this guide rail 5, and is fixed on base 1.
The fixture that is exclusively used in computer rotation shaft of this enforcement, regulation moving hand-held pole 46, make second connecting rod 45 rotate around the first Connection Block 43, the first Connection Block 43 can rotate relative to the second Connection Block 44 simultaneously, under the first Connection Block 43 rotates, drive first connecting rod 42 and rotate, thereby promote the flexible of push rod 40.
It specifically is implemented as follows:
promote to regulate hand-held pole 46, make second connecting rod 45 clockwise rotate around the first Connection Block 43, namely the first Connection Block 43 clockwise rotates around the second Connection Block 44, by clockwise rotating of first connecting rod 42, promoting push rod 40 again moves forward on push rod bearing 41 along self length direction, thereby it is close to the first module 2 to promote the second module 3, rotating shaft is fixed in the die cavity of the first groove 20 and the second groove 30 formation, thereby realize the fixing of rotating shaft, first connecting rod 42 and the second connecting rod 45 of this moment turn to limit, form self-locking, prevent that push rod 40 is to after-contraction, thereby stable is fixed on rotating shaft in die cavity.In addition, in order further to coordinate the work of top-pushing mechanism 4, on base 1, be provided with two guide rails 5, in the bottom of the second module 3, be provided with corresponding guide-track groove 31, make push rod 40 when promotion the second module 3 is traversing along the width of base 1, more steady.
otherwise, pull and regulate hand-held pole 46, make second connecting rod 45 rotate counterclockwise around the first Connection Block 43, namely the first Connection Block 43 rotates counterclockwise around the second Connection Block 44, by rotating counterclockwise of first connecting rod 42, promoting push rod 40 again moves on push rod bearing 41 backward along self length direction, thereby pull the second module 3 to break away to the first module 2, realize the release of top-pushing mechanism 4, thereby rotating shaft is taken out in the die cavity that is fixed on the first groove 20 and the second groove 30 formation, simultaneously in order further to coordinate the work of top-pushing mechanism 4, on base 1, be provided with two guide rails 5, in the bottom of the second module 3, be provided with corresponding guide-track groove 31, make push rod 40 when pulling the second module 3 traversing along the width of base 1, more steady.
In sum, the present invention is according to the profile of rotating shaft, selects the first groove and the second groove shapes, makes the profile of die cavity that the first groove and the second groove be spliced into and rotating shaft identical, thereby stably be arranged on rotating shaft in die cavity, adopt simultaneously the top-pushing mechanism with auto-lock function, effectively reduced distortion and loosening phenomenon in the rotating shaft process, improve the accuracy of rotating shaft processing, in addition, of the present invention simple in structure, it is convenient to implement, and cost is low.
Above the present invention is described in detail; its purpose is to allow the personage who is familiar with this art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; the equivalence that all Spirit Essences according to the present invention are done changes or modifies, and all should be encompassed in protection scope of the present invention.
