Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] as attached figure 1 As shown, a slow-closing and smooth-opening servomotor includes an oil chamber, a partition and a piston with a push rod in the oil chamber. The partition divides the oil chamber into an opening chamber and a closing chamber. The opening chamber and the The closed cavity is provided with an oil port, and the bottom of the open cavity is also provided with a damping oil hole. At the same time, the bottom of the open cavity is also provided with an oil circuit communicating with the open cavity. A check valve is provided on the oil circuit. The flow direction of the valve is from the outside of the open chamber to the inside. When the piston is pushed into the limit position of the opening chamber, the oil connection port on one side of the opening chamber is blocked and closed by the piston.

[0013] In the present invention, a damping hole...

Abstract

The invention discloses a servomotor capable of being slowly stopped and smoothly started. The servomotor capable of being slowly stopped and smoothly started comprises an oil cavity, a partition plate and a piston which is arranged in the oil cavity and provided with a push rod. The oil cavity is divided into a starting cavity and a stopping cavity by the partition plate. The starting cavity and the stopping cavity are respectively provided with an oil receiving port. A damping oil hole is further formed in the bottom of the starting cavity. The bottom of the starting cavity is further provided with an oil channel communicated with the starting cavity. A one-way valve is arranged on the oil channel. The flow direction of the one-way valve is from the outside of the starting cavity to the inside of the starting cavity. The servomotor capable of being slowly stopped and smoothly started is simple in structure and solves the problems that when an existing servomotor is stopped, the existing servomotor is prone to colliding with the bottom of an oil cylinder due to the inertia of a device, and parts are damaged.

Description

technical field [0001] The invention belongs to water conservancy and hydropower mechanical equipment, in particular to a servomotor. Background technique [0002] In the prior art, when the servomotor is closed, due to the inertia of the equipment, it is easy to collide with the bottom of the oil cylinder and damage the parts. On the one hand, this device solves the problem that the servomotor collides with the bottom of the oil cylinder due to inertia when it is closed, and on the other hand, it solves the problem that the servomotor can move smoothly when it is opened to ensure the working efficiency of the equipment. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a slow closing and smooth opening type servomotor, which can make the servomotor have the function of slow closing and smooth opening. [0004] Technical solution: In order to achieve the above purpose, the pr...
