Abstract

The utility model discloses a thin cylinder, which relates to an improved structure of a cylinder and comprises a dustproof ring, a front cover, a piston rod component (consisting of a piston rod, a piston, a sealing ring, a magnetic ring and an abrasion-resistant ring), a cylinder barrel and a rear cover. The front cover and the rear cover are connected to the front end and the rear end of the cylinder barrel by screws, grooves are respectively arranged on one surface, which is opposite to the cylinder barrel, of the front cover and on one surface, which is opposite to the cylinder barrel, of the rear cover, sealing rings and anti-collision cushions are arranged in the grooves, the thin end of the front of the piston component is positioned in a hole on the front cover, two grooves are disposed on the circumference of the thick end of the rear of the piston component, the sealing ring is mounted in the groove of the piston component in the direction of the front cover, the magnetic ring is mounted at the inner bottom of the groove positioned on the rear of the piston component, the abrasion-resistant ring is mounted on the outside of the magnetic ring, the magnetic ring is narrower than the abrasion-resistant ring, and the dustproof ring is sleeved in the inner hole of the front cover, prevents dust from entering the cylinder and prevents gas leakage inside a cylinder barrel. The thin cylinder solves problems that existing like products are huge in structure, large in occupied space and waste materials.

Description

Slim cylinder

Technical field

The utility model relates to the improvement structure of air cylinder structure.

Background technique

There is following shortcoming in existing cylinder: structure is huge, and it is big to take up room, waste material, and above-mentioned shortcoming causes the cylinder restricted application.

The model utility content

The utility model provides a kind of slim cylinder, the utility model structure the structure that exists of existing like product huge, it is big to take up room, the problem of waste material.

For addressing the above problem, the utility model adopts following technological scheme: be made of dust ring 2, protecgulum 3, piston assembly 7, seal ring 8, magnet ring 9, wear ring 10, cylinder barrel 11 and bonnet 14; Protecgulum 3 and bonnet 14 are connected cylinder barrel 11 front end and back end by screw; The one side that protecgulum 3 and bonnet 14 and cylinder barrel 11 are relative is fluted, is provided with seal ring and bumper in this groove; Piston assembly 7 anterior thin ends are arranged in the hole on the protecgulum 3; Piston assembly 7 rear portion butt end excircles have two grooves, in the groove of protecgulum 3 directions seal ring 8 are installed, and the groove inner bottom part that is positioned at the rear portion is equipped with magnet ring 9, and magnet ring 9 outsides are equipped with wear ring 10, and magnet ring 9 is narrower than wear ring 10; Dust ring 2 is set in piston assembly 7 front portions between the endoporus of piston assembly 7 and protecgulum 3.

Advantage of the present utility model has: 1. compact type short stroke air cylinder structure compactness, it is little to take up room, make conventional cylinder do not influence under the situation that cylinder exerts oneself with common cylinder mutually this, can save more than 50% the space; 2. save material more than 50%, also reduced the energy simultaneously; 3. the inner impact of adopting the polyurethane bumper to reduce cylinder; Prolong cylinder working life; 4. multiple mounting type can be arranged, be used for fixing fixation workpiece etc. in anchor clamps and the carrying.

Embodiment

As shown in Figure 1, a kind of slim cylinder is made of dust ring 2, protecgulum 3, piston assembly 7, seal ring 8, magnet ring 9, wear ring 10, cylinder barrel 11 and bonnet 14; Protecgulum 3 and bonnet 14 are connected cylinder barrel 11 front end and back end by screw; The one side that protecgulum 3 and bonnet 14 and cylinder barrel 11 are relative is fluted, is provided with seal ring and bumper in this groove; Piston assembly 7 anterior thin ends are arranged in the hole on the protecgulum 3; Piston assembly 7 rear portion butt end excircles have two grooves, in the groove of protecgulum 3 directions seal ring 8 are installed, and the groove inner bottom part that is positioned at the rear portion is equipped with magnet ring 9, and magnet ring 9 outsides are equipped with wear ring 10, and magnet ring 9 is narrower than wear ring 10; Dust ring 2 is set in piston assembly 7 front portions between the endoporus of piston assembly 7 and protecgulum 3.

Working procedure:

The slim cylinder of ADVU is by piston rod protecgulum piston cylinder and bonnet series connection, and the centre has multiple Sealing to seal.It is reciprocating that protecgulum and bonnet take turns air intake-exhaust.The structure emphasis:

1, front and rear covers and cylinder barrel lump together the shell that constitutes product by set screws, and there is seal ring front and rear covers and cylinder barrel contact position; Piston assembly, seal ring, magnet ring, wear ring constitute piston main body, but piston main body to-and-fro motion in cylinder barrel; Front and rear covers and piston connect the main body contact position and all are lined with bumper.

2, bonnet is square, and respectively there is a screw hole at four angles, and screw passes from the hole; The groove of a circle is arranged on bonnet and the face that cylinder barrel contacts, and notch is provided with a step, and the O RunddichtringO is installed at the notch edge, and bumper is installed on the step.

3, protecgulum is square, and respectively there is a screw hole at four angles, and screw passes from the hole, and the groove of a circle is arranged on protecgulum and the face that cylinder barrel contacts, and notch is provided with a step, and the O RunddichtringO is installed at the notch edge, and bumper is installed on the step; The protecgulum center is provided with a hole, and the bar of piston set bar stretches out from the hole.

4, cylinder barrel external square, internal diameter is identical with groove internal diameter on the front and rear covers, and the two ends corner location respectively has a screw, and the screw that passes from four jiaos of holes of front and rear covers screws in the screw.

5, piston assembly is divided in two parts, and the front portion is cylindrical thinner piston rod, stretches out from the center hole of protecgulum bottom land.The rear portion is thicker, and diameter and internal diameter of cylinder are suitable, and posterior face has two grooves, and the groove that is positioned at the protecgulum direction is installed seal ring, and the groove that is positioned at the bonnet direction is the groove of a stepped shape, and magnet ring is installed in the bottom, and wear ring is installed on top, and wear ring is slightly wideer than magnet ring.

6, dust ring is installed in the hole at protecgulum center, is enclosed within on the piston assembly front piston rod.

It should be noted that at last: obviously, the foregoing description only is for the utility model example clearly is described, and is not the qualification to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation of being amplified out thus or change still are among the protection domain of the present utility model.
