Embodiment 1

[0033] Such as figure 1 The cylinder-piston mechanism shown includes a slider 1, a piston 2, a slideway 101 and a cylinder 201, the slider 1 and the slideway 101 are reciprocally slidable, and the cylinder 201 and the slideway 101 are fixed Connected, the piston 2 is set in the cylinder 201 and is in sliding and sealing fit with the cylinder 201, the piston 2 is connected with the slider 1 in single action, and the cylinder 201 is provided with a pressure fluid flow port 3 .

[0034] When the slider 1 moves upward, the slider 1 pushes the piston 2 to move upward to the top dead center position, and when the piston 2 crosses the top dead center, the high-pressure fluid in the cylinder of the cylinder-piston mechanism Push the piston 2 to move close to the bottom dead center of the slider 1 . Since the piston 2 and the slider 1 are single-acting connected, the slider 1 will not transmit any lateral force to the piston 2 (or only a small lateral force will be transmitted to th...

Embodiment 2

[0037] Such as figure 2 The difference between the cylinder-piston mechanism shown in Embodiment 1 is that the cylinder 201 and the slideway 101 are integrated instead.

[0038] Optionally, all the embodiments of the present invention in which the cylinder 201 and the slideway 101 are fixedly connected can refer to this embodiment to change the cylinder 201 and the slideway 101 into an integrated arrangement.

Embodiment 3

[0040] Such as image 3 In the shown cylinder-piston mechanism, on the basis of Embodiment 1, the slider 1 is set as a lateral force piston 21 , and the slideway 101 is set as a lateral force cylinder 102 .

[0041] Optionally, the side force cylinder 102 and the side force piston 21 may be in a sealing fit or a non-sealing fit.

[0042] In actual application, the slider 1 and the slideway 101 can also be selectively set to other structures, for example, the slideway 101 is set as an open guide rail structure, and the slider 1 is set to be compatible with the The slider structure matched with the guide rail structure.

Abstract

The invention discloses a cylinder-piston mechanism, comprising a sliding block, a piston, a slideway and a cylinder, wherein the sliding block and the slideway are in reciprocating sliding fit, and the cylinder and the slideway are fixedly connected or integrally arranged. The piston is arranged in the cylinder and is slidingly and sealingly matched with the cylinder. The piston is single-actingly connected with the slider, and a pressurized fluid flow port is arranged on the cylinder. The piston in the cylinder-piston mechanism of the present invention receives less lateral force and requires less lubrication between the piston and the cylinder, which can reduce or even avoid the influence of the lubricant on the working fluid in the cylinder.

Description

technical field [0001] The invention relates to the technical field of mechanical power, in particular to a cylinder-piston mechanism. Background technique [0002] When the traditional cylinder-piston mechanism works, when the piston slides in the cylinder, there is a large lateral force (force along the radial direction of the cylinder) between the piston and the cylinder, resulting in a large friction force between the piston and the cylinder. Therefore, it is necessary to use a lubricant to lubricate the contact surface between the piston and the cylinder, so it is inevitable that some lubricant will be mixed into the working fluid in the cylinder. Under the condition that the lubricant cannot be mixed with the working fluid, the existing cylinder-piston mechanism cannot meet the working requirements. Contents of the invention [0003] In order to solve the above problems, the technical scheme proposed by the present invention is as follows: [0004] A cylinder-pisto...
