The adjusting screw penetrates the upper and lower supporting plates and is matched with holes of the upper and lower supporting plates. The adjusting screw comprises a polished rod section, a limit table and a threaded section from the bottom to the top successively. A circle of snap groove is formed in the lower section of the polished rod section, and the snap spring is arranged at the snap groove. The distance between the snap spring and the limit table is equal to the difference of the lower supporting plate thickness and the counter bore depth. The lock nut is arranged between the upper and lower supporting plates and is matched with the threaded section of the adjusting screw. The limit table is hexagonal, and the washer is disposed between the upper supporting plate and the lock nut. An anti-rotation boss is arranged on each of the upper and lower supporting plates. By means of the mechanism, snapping deformation and machining shaking of U-shaped lug parts can be achieved; the mechanism is simple in structure, convenient to operate, capable of improving the machining efficiency effectively and provided with certain practical application values.
Description
Technical field
The utility model belongs to jig technology, relates to a kind of fork ear part supporting mechanism.
Background technology
Having aboard some part terminations is U-shaped fork ear, and turnning and milling processing easily produces distortion when clamping, or easily produces and tremble when milling profile, affects Product Precision, even causes scrapping.Be pressure plate on fork ear what adopted in the past, this method exists hold down gag impact processing cutter track, and need to alternately compress multiple clamping and just can complete processing, the bad guarantee of machining accuracy, working (machining) efficiency is low.
Utility model content
Technical problem to be solved in the utility model is: a kind of fork ear part supporting mechanism is provided, and simple in structure, easy to operate, effectively improve working (machining) efficiency and machining accuracy.
The technical solution of the utility model is: a kind of fork ear part supporting mechanism, is characterized by: described supporting mechanism comprises jump ring, adjusting screw(rod), upper backup pad, lower supporting plate, locking nut, packing ring: upper backup pad has a screwed hole; Lower supporting plate has a through hole, and the outer part of through hole is counterbore; Adjusting screw(rod) passes upper and lower support plate and matches with the hole of upper and lower support plate; Described adjusting screw(rod) is followed successively by polished rod section, limiting stand, thread segment from below to up; Wherein polished rod pars infrasegmentalis has a circle draw-in groove, and jump ring is housed on draw-in groove; The distance of jump ring and limiting stand equals the poor of lower supporting plate thickness and the counterbore degree of depth; Polished rod section is less than lower supporting plate thickness; Adjusting screw(rod) total length is less than the prong width of fork ear part; Locking nut, between upper and lower support plate, coordinates with the thread segment of adjusting screw(rod); Limiting stand profile is outer-hexagonal; Packing ring is between upper backup pad and locking nut; Described upper backup pad has an anti-rotation boss; Described lower supporting plate has an anti-rotation boss.
The beneficial effects of the utility model are: a kind of fork of the utility model ear part supporting mechanism, and can realize U-shaped fork ear part and prevent that clamping deformation and processing from trembling, simple in structure, easy to operate, effectively improve working (machining) efficiency, there is certain actual application value.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further details.
Referring to Fig. 1, a kind of fork ear part supporting mechanism, comprises jump ring 1, adjusting screw(rod) 2, upper backup pad 3, lower supporting plate 4, locking nut 5, packing ring 6: upper backup pad 3 has a screwed hole; Lower supporting plate 4 has a through hole, and the outer part of through hole is counterbore; Adjusting screw(rod) 2 passes upper and lower support plate 3,4 and matches with the hole of upper and lower support plate 4.Referring to Fig. 2, described adjusting screw(rod) 2 is followed successively by polished rod section 8, limiting stand 9, thread segment 10 from below to up.Wherein a circle draw-in groove is arranged at polished rod section 8 bottoms, and jump ring 1 is housed on draw-in groove; Jump ring 1 equals the poor of lower supporting plate 4 thickness and the counterbore degree of depth with the distance of limiting stand 9; Polished rod section 8 is less than lower supporting plate 4 thickness; Adjusting screw(rod) 2 total lengths are less than approximately 2～3mm of prong width; Locking nut 5, between upper and lower support plate 4, coordinates with the thread segment 10 of adjusting screw(rod) 2; Limiting stand 9 profiles are outer-hexagonal; Packing ring 6 is between upper backup pad 3 and locking nut 5, and described upper backup pad 3 has an anti-rotation boss 11, the high 3～5mm of boss; Described lower supporting plate 4 has an anti-rotation boss 11, the high 3～5mm of boss; Described anti-rotation boss 11, for rotating adjusting screw(rod) 2 processes, prevents that upper and lower support plate from rotating, and can hang on U-shaped fork ear 7 in addition in the time that supporting mechanism erects to use, and bears supporting mechanism weight.
A kind of fork of the utility model ear part supporting mechanism, in use, first adjusting screw(rod) 2 polished rod sections are coordinated to assembling with 4 strokes of lower supporting plates, and form an assembly by jump ring 1 axial locking, locking nut 5 is screwed into the thread segment 10 of adjusting screw(rod) 2, then puts packing ring 6; Again upper backup pad 3 screwed holes are screwed into the thread segment 10 of adjusting screw(rod), form a complete assemblies, this assembly is put into the U-shaped fork ear of workpiece 7 places, with spanner rotation adjusting screw(rod) 2 limiting stands 9, thereby upper backup pad 3 is moved axially, when moving to while better reclining U-shaped fork ear, rotational lock nut 5, now tool structure and workpiece form a good assembly of rigidity, can clamping processing.
When process finishing, first rotational lock nut 5 slow astern set a distances, then rotate adjusting screw(rod) 2, make to move back in upper backup pad 3, take off whole supporting mechanism, complete a workpiece processing.
A kind of fork of the utility model ear part supporting mechanism, can realize U-shaped fork ear part and prevent that clamping deformation and processing from trembling, simple in structure, easy to operate, effectively improves working (machining) efficiency, has certain actual application value.
