Abstract
The utility model discloses an anti - formula master cylinder of adorning for hydraulic press, including the cylinder body, locate having pole chamber hydraulic fluid port and not having pole chamber hydraulic fluid port, piston rod and piston, its characterized in that on the cylinder body the cylinder body is equipped with the shoulder hole of little -endian after to in the past, and the rear end of cylinder body has connected firmly the cylinder bottom, and the front end of piston rod passes the shoulder hole and is located outside the cylinder body, circle and cylinder bottom excircle all are equipped with the sealing washer in the cylinder body front end, and the front end excircle and the rear end excircle of cylinder body equal. The utility model discloses both reduced size, the cost is reduced, the installation of being convenient for again, use, and eliminated the hidden danger of leaking.
Description
Technical field
The utility model relates to a kind of master cylinder for oil hydraulic press.
Background technique
At present, for the master cylinder of oil hydraulic press, as shown in Figure 1, comprise cylinder body 11, be located at rod chamber hydraulic fluid port 12 on cylinder body 11 and rodless cavity hydraulic fluid port 13, piston rod 14 and piston 15, cylinder body 11 back-end closure, cylinder body 11 is provided with descending shoulder hole from front to back, is installed with guide sleeve 17 by gland 16 at cylinder body 11 Inner Front End, and piston rod 14 front end is through guide sleeve 17; This oil cylinder is installed by upside up type, for realizing quick return, its speed ratio is comparatively large, and namely piston rod 14 diameter differs very little with cylinder body 11 back end inside diameter, and in the course of the work, piston rod 14 can apply axial force to guide sleeve 17, and this not only easily causes guide sleeve 17 to loosen, cause leakage, and for increasing guide sleeve 17 intensity, its radial dimension is larger, this must cause master cylinder front end size comparatively large, both increases cost, is not easy to again install, use.
Summary of the invention
The purpose of this utility model is for prior art above shortcomings, and provide a kind of anti-dress formula master cylinder for oil hydraulic press, it had both reduced size, has reduced cost, is convenient to again install, use, and eliminates the hidden danger of leakage.
For achieving the above object, anti-dress formula master cylinder for oil hydraulic press of the present utility model, comprise cylinder body, be located at rod chamber hydraulic fluid port on cylinder body and rodless cavity hydraulic fluid port, piston rod and piston, it is characterized in that described cylinder body is provided with ascending shoulder hole from front to back, the rear end of cylinder body is fixedly connected with cylinder bottom, and the front end of piston rod is positioned at outside cylinder body through shoulder hole; Be equipped with seal ring in cylinder body front end inner circle and cylinder bottom cylindrical, front end cylindrical and the rear end cylindrical of cylinder body are equal.
The utility model by arranging ascending shoulder hole from front to back in cylinder body, former cylinder body, guide sleeve, gland are integrated, its front end cylindrical and rear end cylindrical equal, not only structure is simple, size is little, both cost was reduced, be convenient to again install, use, and avoid the leakage hidden danger that former guide sleeve causes; This master cylinder is installed by the anti-mode that fills, and installs cylinder bottom after namely first installing piston rod;
As further improvement of the utility model, described cylinder bottom is provided with positioning step and passes through scyewed joint with cylinder body; Both connected conveniently, be convenient to again location;
In sum, the utility model had both reduced size, had reduced cost, was convenient to again install, use, and eliminated the hidden danger of leakage.
Accompanying drawing explanation
Fig. 1 is the plan view of existing main oil cylinder of oil press.
Fig. 2 is the plan view of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, this is used for the anti-dress formula master cylinder of oil hydraulic press, comprise cylinder body 1, be located at rod chamber hydraulic fluid port 2 on cylinder body 1 and rodless cavity hydraulic fluid port 3, piston rod 4 and piston 5, described cylinder body 1 is provided with ascending shoulder hole 6 from front to back, the rear end of cylinder body 1 is fixedly connected with cylinder bottom 7 by screw thread, cylinder bottom 7 is provided with cylinder body 1 positioning step matched, and the front end of piston rod 4 is positioned at outside cylinder body 1 through shoulder hole 6; In cylinder body 1 front end, inner circle is provided with seal ring 8, is equipped with seal ring 9 at cylinder bottom 7 cylindrical, and front end cylindrical and the rear end cylindrical of cylinder body 1 are equal.
The utility model by arranging ascending shoulder hole 6 from front to back in cylinder body 1, former cylinder body, guide sleeve, gland are integrated, its front end cylindrical and rear end cylindrical equal, not only structure is simple, size is little, both cost was reduced, be convenient to again install, use, and avoid the leakage hidden danger that former guide sleeve causes; This master cylinder is installed by the anti-mode that fills, and installs cylinder bottom 7 after namely first installing piston rod 4; Described cylinder bottom 7 connects convenient with cylinder body 1, be convenient to again location.
