Utility model content

The purpose of this utility model is to overcome current hydraulic cylinder to there is the deficiency that stroke is fixed or the adjustment of stroke regulating structure complexity is difficult, it is provided that a kind of simple in construction and the convenient range-adjustable hydraulic cylinder of stroke adjustment.

Concrete technical scheme of the present utility model is:

A kind of range-adjustable hydraulic cylinder, including cylinder body, rod chamber cylinder cap and rodless cavity cylinder cap, rear end is provided with piston and the piston rod of rod chamber cylinder cap is stretched out in front end;Described range-adjustable hydraulic cylinder also includes: regulates axle, is provided with the adjusting nut of mesopore;Piston rod rear end is provided with the degree of depth screw more than adjusting nut thickness;Rodless cavity cylinder cap is provided with through hole;Adjustment axle includes: being arranged in screw and front end is provided with the leading portion of baffle ring, diameter is less than the back segment of leading portion diameter;Through hole back-end is stretched out in the rear end of back segment and through hole pivot joint and back segment;Mesopore is enclosed within outside leading portion, and adjusting nut is threadeded with screw;Axial slide rail it is provided with between adjusting nut and leading portion.When this range-adjustable hydraulic cylinder uses, rotating back segment, leading portion drives adjusting nut to rotate and axially-movable done by adjusting nut under screw coordinates through axial slide rail, by changing distance between adjusting nut and baffle ring opposite face thus changing the stroke of hydraulic cylinder;Back segment is connected with motor the stroke that can realize being automatically adjusted hydraulic cylinder on request.This range-adjustable hydraulic cylinder structure is simple and stroke adjustment convenient.

As preferably, described slide rail includes: the axial slide that mesopore gusset is provided with, the axial feather key that leading portion gusset is provided with.Rail structure is simple and reliable.

As preferably, described through hole gusset is provided with labyrinth sealing groove.Improve the sealing between through hole and back segment.

As preferably, the rear end of described back segment is provided with keyway.It is easy to be connected with driving device.

Compared with prior art, the beneficial effects of the utility model are: this range-adjustable hydraulic cylinder structure is simple and stroke adjustment convenient.Rail structure is simple and reliable.Through hole gusset is provided with labyrinth sealing groove, improves the sealing between through hole and back segment.The rear end of back segment is provided with keyway, it is simple to be connected with driving device.

Accompanying drawing explanation

Fig. 1 is a kind of structural representation of the present utility model.

In figure: cylinder body 1, rod chamber cylinder cap 2, rodless cavity cylinder cap 3, piston 4, piston rod 5, adjustment axle 6, mesopore 7, adjusting nut 8, screw 9, through hole 10, baffle ring 11, leading portion 12, back segment 13, axial slide 14, axial feather key 15, labyrinth sealing groove 16, keyway 17.

Detailed description of the invention

Below in conjunction with shown in accompanying drawing, this utility model is described further.

As shown in Figure 1: a kind of range-adjustable hydraulic cylinder, including cylinder body 1, rod chamber cylinder cap 2, rodless cavity cylinder cap 3, rear end is provided with piston 4 and the piston rod 5 of rod chamber cylinder cap is stretched out in front end, regulates axle 6, is provided with the adjusting nut 8 of mesopore 7;Piston rod 5 rear end is provided with the degree of depth screw 9 more than adjusting nut 8 thickness;Rodless cavity cylinder cap 3 is provided with through hole 10;Regulate axle 6 to include: being arranged in screw 9 and front end is provided with the leading portion 12 of baffle ring 11, diameter is less than the back segment 13 of leading portion 12 diameter;Through hole 10 rear end is stretched out in the rear end of back segment 13 and through hole 10 pivot joint and back segment 13;Mesopore 7 is enclosed within outside leading portion 12, and adjusting nut 8 is threadeded with screw 9;Axial slide rail it is provided with between adjusting nut 8 and leading portion 12.
