Description

Mechanical cylinder

The utility model relates to a kind of Mechanical cylinder, belongs to the technical field of mechanical parts.

In the driving mechanism of machinery, the own unique advantage of hydraulic transmission, but its element such as oil hydraulic cylinder etc., still have many shortcomings, since the defective of machining accuracy, the cylinder body difficult sealing, Sealing is easily aging, often causes serious leakage of oil, and needs the various hydrovalves of adapted, oil pipe in the pressurized oil system, also make part many, structure complicated, installation, maintenance is time-consuming, part is fragile, cost is higher or the like, makes its use, and certain narrow limitation is arranged.

The purpose of this utility model is that a kind of Mechanical cylinder will be provided, and it can overcome above-mentioned shortcoming, designs simplification, and nothing is easy to leakage of oil, is easy to defectives such as damage and cost height.

The purpose of this utility model is to realize like this, in the inner cylinder tube of Mechanical cylinder screw is housed, cylinder head is contained in inner cylinder tube top, pin-and-hole is arranged at cylinder head top, can fix other parts with bearing pin, stuffing box gland is equipped with in the inner cylinder tube outside, and the silk cylinder is contained in the screw, and the screw mandrel lower end connects a coupling shaft with connecting pin, there is boss in the axle outside, bearing all is equipped with in the top and bottom of boss, respectively has a back-up ring to be located, and the outside, outer cylinder bottom is with overcoat, overcoat also has pin-and-hole, utilize pin can fix other parts, the screw mandrel lower end is connected with motor shaft, and the motor rotary screw rod rotates inner cylinder tube can be moved in outer cylinder.

Fig. 1 is the schematic representation of Mechanical cylinder.

Now in conjunction with the accompanying drawings the structure of Mechanical cylinder is described in detail.

By Fig. 1, cylinder head (1) is fixed on above the inner cylinder tube (2), screw (3) is contained in the inner cylinder tube (2), be connected with its lower end, pin-and-hole (19) is arranged at the top of cylinder head (1), available bearing pin is connected with other other parts of machinery, the stuffing box gland (13) of bellows form is equipped with in the outside of inner cylinder tube (2), screw mandrel (5) upper end is contained in the screw (3), the lower end is connected with coupling shaft (7) with connecting pin (6), there is boss (19) in the outside of coupling shaft (7), on the boss (19), following two ends are equipped with bearing (16) and (18) respectively, bearing (16) is located by back-up ring (15), this back-up ring (15) is contained in the outer cylinder (3), bearing (18) is located by back-up ring (9), back-up ring (9) is loaded between overcoat (8) and the motor (11), overcoat (8) is contained on the motor (11), the outside, bottom of outer cylinder (4) is with overcoat (8), the outside, outer cylinder (4) bottom, top in overcoat (8), has pin-and-hole (17), can utilize pin that fixed component is connected in pin-and-hole (17) during use, outer cylinder (4) inner chamber forms an outer cylinder body (14), inner cylinder tube (2) inner chamber is an inner cylinder body (12), screw mandrel (5) lower end is connected with the output shaft of motor (11), motor rotating band movable wire bar (5) rotates, so screw (3) drives inner cylinder tube (2) and moves, the clockwise and anticlockwise of motor (11) also makes the change of leading screw (5) gyratory directions, makes on the inner cylinder tube (2), move to and fro.

Compared with prior art, Mechanical cylinder has following advantages:

Simple in structure, be easy to make, reliable in action.

2. the effect of alternative cylinder device, no easy oil leakage, shortcoming such as fragile.

3. cost is low, suits practicality.
