Abstract
The utility model discloses a closing device of a valve rotating device. The closing device comprises an upper die body, an upper die, a lower die and a lower die cushion, wherein the lower die is installed on the lower die cushion, and the upper die is installed on the upper die body; and a closing mouth with angularity is arranged on a lower center of the upper die, and an upper center of the lower die is provided with a rotating cap step positioning hole. Through the rotating cap step positioning hole in the upper center of the lower die, the traditional planar positioning of a rotating cap is improved to planar and excircle positioning of the rotating cap, so that the positioning precision of the rotating cap is improved; and in addition, the closing mouth with the angularity is arranged on the lower center of the upper die, so that the valve rotating mechanism can be assembled and closed in the descending process of the upper die, and the automation degree is high. After the closing device is adopted to assemble and close the valve rotating mechanism, the assembled and closed valve rotating mechanism is flexible to rotate without being seized.
Description
Technical field:
The utility model relates to a kind of valve rotating mechanism closing device, and this device can use with hydraulic pressure, oil pressure unit jointly, is used for high-quality, high efficiency valve rotating mechanism assembling closing in.
Background technology:
Valve rotating mechanism substitutes following of traditional valve spring, supports valve spring, and can drive the valve rotation by mandatory order; And then reach the cleaning valve-face carbon distribution; Valve is heated evenly, improves valve group lubricating condition, improve valve service life and pitting corrosion resistant performance; Therefore require the valve rotating mechanism assembling to close up evenly, rotate flexibly.Present employed valve rotating device closing in skilled labour intensity is big, and assembling is closed up inhomogeneous, rotates dumbly, can't satisfy main engine plants' requirement of client.
The utility model content:
The utility model technical problem to be solved is the deficiency that overcomes above-mentioned existing valve rotating mechanism assembling closing in technology, and a kind of novel valve rotating mechanism closing device that provides.
The utility model technical problem to be solved can realize through following technical scheme:
A kind of valve rotating mechanism closing device comprises upper die body, upper die and lower die, following die-cushion, and said counterdie is installed on the said die-cushion down, and said patrix is installed on the said upper die body; Lower central at said patrix is provided with the oral area that tightens up that has angle, is provided with rotating cap step locating hole in said counterdie central upper portion.
Owing to adopted technique scheme, the utility model can will have the rotating cap plane positioning now and be improved to by rotating cap plane and cylindrical location through the rotating cap step locating hole of counterdie central upper portion, improve the positioning accuracy of rotating cap; Be provided with the oral area that tightens up that has angle in the patrix lower central in addition, can be to valve rotating mechanism assembling closing in the descending process of patrix, automaticity is high.After adopting the utility model assembling being closed up to valve rotating mechanism, can realize the rotation hair fastener not flexibly after the valve rotating mechanism assembling has been closed up.
The valve rotating mechanism closing device of the utility model; Cooperation hydraulic press, employing hydraulic pressure drive to descend realizes that closing in and rising eject material automatically and reach the closing in target, and it is high to have closing in efficient; Fireballing advantage has solved the high problem of labour intensity that existing craft is closed up and brought on vice.The utility model is fit to be applied to hydraulic pressure, oil pressure unit, is well suited for main engine plants' requirement of client.
Description of drawings:
Fig. 1 is the structural representation of the utility model valve rotating mechanism closing device.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, a kind of valve rotating mechanism closing device shown in the figure comprises upper die body 1, patrix 2, counterdie 3, following die-cushion 4, and counterdie 3 is installed in down on the die-cushion 4, and patrix 2 is installed on the upper die body 1; The lower central of patrix 2 be provided with have an angle tighten up oral area 5, be provided with rotating cap step locating hole 6 in counterdie 3 central upper portion.
This valve rotating mechanism assembles closing device and can realize advancing material loading, automated exchanged cutter by hand, closes up automatically, returns automatically and be with the material of leaving behind by hand, thereby the pitch time that these semi-automatic functions can be controlled each step flexibly by program on the hydraulic press satisfies the production demand.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
