Abstract
The utility model relates to a hydraulic machine, in particular to an adjustable hydraulic cylinder belonging to the technical field of machining operation. The hydraulic cylinder comprises a cylinder body which is internally provided with a piston rod, and a guide sleeve is fixed between the cylinder body and the piston rod by a flange and a bolt. The adjustable hydraulic cylinder is characterized in that a plurality of base plates are arranged between the bottom of the cylinder body and a sliding block, grooves are arranged at the middle parts of the base plates, and square anti-rotation pins are arranged in the grooves. By adjusting the number of the base plates, the height and the stroke of the opening of the hydraulic machine can be adjusted, so that the problem that the hydraulic machine can not meet the variation and flexibility of processing parts can be solved; the base plates can be adjusted to be smaller, the processing is convenient and rapid, and the problem that large-size parts are inconvenient to process is solved; and the adjustable hydraulic cylinder has a compact and simple structure, and is convenient in promotion and application.
Description
Technical field
The utility model relates to a kind of hydraulic press, is specifically related to a kind of adjustable hydraulic cylinder, belongs to the Machining Technology field.
Background technique
At present, the open height of hydraulic press and hydraulic cylinder travel are definite values, in order to satisfy the needs of machining large-sized part, the open height of hydraulic press and hydraulic cylinder travel value are bigger, and during this hydraulic press processing reduced size part, can make a large amount of idle works, waste a large amount of energy, increase again and produce auxiliary time, reduce manufacturing efficiency.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, a kind of adjustable hydraulic cylinder is provided, the adjustment cushion block is housed, adjust the quantity of cushion block in cylinder base, can adjust the stroke of oil hydraulic cylinder, also solve the inconvenient problem of large scale oil hydraulic cylinder processing simultaneously.
The utility model is achieved by the following technical solution: a kind of adjustable hydraulic cylinder, this oil hydraulic cylinder includes cylinder body, piston rod is arranged in the cylinder body, by flange, bolt guide sleeve is arranged between cylinder body and the piston rod, it is characterized in that: some backing plates are arranged between described cylinder base and the slide block, the intermediate portion of backing plate has groove, and square stop pin is arranged in the groove.
Between cylinder body and slide block, described backing plate is one or several to described backing plate by opposite opened snap ring, screw.
The beneficial effects of the utility model are: adopt the adjustable hydraulic cylinder, can make a hydraulic press have multiple open height and stroke,, just can adjust the open height and the stroke of hydraulic press by adjusting the quantity of cushion block, solved hydraulic press and can not satisfy the processing accessories variation, the flexibility problem; It is less to adjust the cushion block size, easy to process quick, has solved the inconvenient problem of large-scale part processing; Compact structure, simple is convenient to promotion and implementation.
Description of drawings
With embodiment the utility model is further specified with reference to the accompanying drawings below:
Accompanying drawing is the utility model structural representation:
Among the figure: 1, piston rod, 2, the opposite opened snap ring, 3, cushion block, 4, square stop pin, 5, attachment screw, 6, flange, 7, guide sleeve, 8, cylinder body, 9, bolt, 10, slide block.
Embodiment
As shown in the figure: a kind of adjustable hydraulic cylinder, this oil hydraulic cylinder includes cylinder body 8, piston rod 1 is arranged in the cylinder body, be fixed with guide sleeve 7 by flange 6, bolt 9 between cylinder body and the piston rod, between described cylinder base and the slide block 10 some backing plates 3 are arranged, the intermediate portion of backing plate has groove, and square stop pin 4 is arranged in the groove.
Described backing plate 3 is fixed between cylinder body and the slide block by opposite opened snap ring 2, screw 5, and described backing plate is one or several.
Working procedure: when hydraulic press processing reduced size part, unclamp attachment screw 9, take off and split snap ring 2, this moment, piston rod and slide block broke away from, between piston rod 1 and slide block 10, add and adjust cushion block, adding the quantity of adjusting cushion block decides according to the concrete size of part, the size of part is more little, and the cushion block quantity of interpolation is many more, adds and adjusts after the cushion block 3, the heart groove square stop pin 4 of packing into therein, snap ring and screw are adjusted cushion block with piston rod and slide block is connected and fixed by splitting, and this moment, the hydraulic press opening reduced, and processing small size part is energy-efficient, and this operating process simple and fast, safe and reliable.
