Abstract
The utility model relates to an integral type piston rod. The integral type piston rod includes a piston rod body and is characterized in that the middle of the piston rod body is provided with a piston, and the piston and the piston rod body are integral and concentric. Two sides of the piston are respectively provided with a first section rod body and a second section rod body, and the first section rod body, the second section rod body and the piston are integral and are respectively concentric. The integral type piston rod guarantees the concentricity of the piston rod and the piston, moves freely after assembled and ventilated, and avoids blocking.
Description
Technical field
The utility model relates to a kind of for the piston rod on the cylinder, and especially a kind of one-piece piston bar belongs to the cylinder technical field.
Background technique
The liquid gas pressure cylinder is used very extensive in industrial automation arrangement, and wherein two rod cylinders need the concentricity of piston rod and piston higher for the having relatively high expectations of piston rod and piston.General piston rod and piston are split-type structural in the prior art, and piston rod and piston fit together after manufacturing is finished again, so often concentricity is relatively poor, reject rate is than higher, and underaction after the ventilation has stuck phenomenon.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of one-piece piston bar is provided, and has guaranteed the concentricity of piston rod and piston, and activity has been avoided stuck phenomenon freely after the assembling ventilation.
According to the technological scheme that the utility model provides, described one-piece piston bar comprises the piston rod body, it is characterized in that: the middle part at described piston rod body arranges piston, and piston and piston rod body are as a whole.
Described piston and piston rod body are concentric.
The both sides of described piston are respectively first section body of rod and second section body of rod, and first section body of rod and second section body of rod and piston are as a whole.
Described first section body of rod, second section body of rod and piston are respectively with one heart.
One-piece piston bar described in the utility model has guaranteed the concentricity of piston rod and piston, and activity has been avoided stuck phenomenon freely after the assembling ventilation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As shown in Figure 1: described one-piece piston bar comprises piston rod body 1, piston 2, first section body of rod 1a, second section body of rod 1b etc.
As shown in Figure 1, the utility model comprises piston rod body 1, and one-body molded at the middle part of piston rod body 1 have a piston 2; Described piston 2 and piston rod body 1 are concentric;
The both sides of described piston 2 are respectively first section body of rod 1a and second section body of rod 1b, first section body of rod 1a and second section body of rod 1b all adopt integral processing to make with piston 2, and first section body of rod 1a, second section body of rod 1b and piston 2 are respectively with one heart, thereby the concentricity of this one-piece piston bar is higher, in operation more nimbly and freely, be not prone to stuck phenomenon, be applicable to various slim cylinders.
