Abstract

The invention discloses a rapid cylinder which belongs to the cylinder technology field. The rapid cylinder comprises a cylinder body; the front end of the cylinder body is provided with a front end cover; the rear end of the cylinder body is provided with a rear end cover; a guide sleeve is arranged between the front end cover and the cylinder body; the rear end cover is fixed at the rear end of the cylinder body through a locking block; an inner piston and an external piston are arranged inside the cylinder body; the inner piston and the external piston are used in a matching mode; the inner piston is connected with an inner piston rod; and the external piston is connected with an external piston rod. The rapid cylinder has the advantages of achieving the purpose of rapid extension and retraction, improving the working efficiency and being stable and reliable in operation, easy to maintain and suitable for popularization and application in production operation due to the facts that the inner piston which serves as an internal cylinder internally pushes the external piston rod, the internal cylinder pushes the external piston rod, and two strands of force are acted on the same piston rod.

Description

A kind of quick oil cylinder
Technical field
The invention belongs to the oil cylinder technical field, be specifically related to a kind of quick oil cylinder.
Background technique
At present, the oil hydraulic press that most of enterprises produce has all solved the big low problem of in light weight, energy consumption in addition of work tonnage preferably, but mostly unsatisfactory aspect raising the efficiency under the reliable prerequisite of safety action.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the object of the present invention is to provide a kind of quick oil cylinder, satisfying under the reliable prerequisite of producing, improve the working efficiency of oil cylinder, and then enhance productivity.
Technological scheme: a kind of quick oil cylinder, comprise cylinder body, described cylinder body front end is provided with front cover, and described rear end of the cylinder block is provided with rear end cover, is provided with guide sleeve between described front cover and the cylinder body, and described rear end cover is fixed on the rear end of cylinder body by lock dog; Be provided with the inner carrier and the outer piston that are used in the described cylinder body, described inner carrier links to each other with inner piston rod, and described outer piston links to each other with the outer piston bar.
Described lock dog is fixed on the rear end cover by locking nut.
Described rear end cover is provided with the fixedly gland of rear end cover, and described gland is provided with and cooperates the briquetting that compresses.
Described briquetting is fixed on the gland by locking nut.
The afterbody of described cylinder body also is provided with the oil circuit conversion block.
Beneficial effect: compared with prior art, quick oil cylinder of the present invention, promote in inside as inner oil cylinder by inner carrier, inner oil cylinder external piston bar promotes, two bursts of powers act on the purpose that same piston rod reaches quick-expansion, and when having improved working efficiency, this quick oil cylinder operation is solid and reliable, be easy to maintenance and maintenance, suit in producing running, to apply.
Description of drawings
Fig. 1 is the structural representation of quick oil cylinder.
Embodiment
The present invention is described further below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, this quick oil cylinder comprises cylinder body 11, and cylinder body 11 front ends are provided with front cover 13, and cylinder body 11 rear ends are provided with rear end cover 5, is provided with guide sleeve 12 between front cover 13 and the cylinder body 11, and rear end cover 5 is fixed on the rear end of cylinder body 11 by lock dog 6; Be provided with the inner carrier 7 and the outer piston 8 that are used in the cylinder body 11, inner carrier 7 links to each other with inner piston rod 9, and outer piston 8 links to each other with outer piston bar 10.Wherein, lock dog 6 is fixed on the rear end cover 5 by locking nut 2; Rear end cover 5 is provided with the fixedly gland 4 of rear end cover 5; Gland 4 is provided with and cooperates the briquetting 3 that compresses; Briquetting 3 is fixed on the gland 4 by locking nut 2; The afterbody of cylinder body 11 also is provided with oil circuit conversion block 1.
Working procedure: promote in inside as inner oil cylinder by inner carrier 7, inner oil cylinder external piston bar 9 promotes, and two bursts of powers act on the purpose that same piston rod reaches quick-expansion, have improved working efficiency.
This quick oil cylinder, promote in inside as inner oil cylinder by inner carrier, inner oil cylinder external piston bar promotes, two bursts of powers act on the purpose that same piston rod reaches quick-expansion, when having improved working efficiency, this quick oil cylinder operation is solid and reliable, is easy to maintenance and maintenance, suits to apply in producing running.
