Problems solved by technology

At present, the lubrication performance of the guide rail is artificially observed, and the lubricating oil is artificially added according to the lubricity of the guide rail, which will sometimes cause the lubrication characteristics of the guide rail to deteriorate due to the negligence of the operator, and the accuracy and stability will decrease.
Of course, in addition to linear guides, in many lubricating environments, the current addition of lubricating oil is mainly manual addition, and the operation method of manual addition often means that the lubrication environment is destroyed

Embodiment 1

[0017] as attached figure 1 As shown, a lubricating oil automatic filling device includes an oil storage chamber 1, a suction pump, the suction pump includes a pump body 2, the pump body is provided with an upper end cover 3 and a lower end cover 4, and the pump body is provided with a piston 5, The edge of the piston 5 is in sealing contact with the inner wall of the pump body 2 , the piston 5 is connected to the piston rod 6 , and the top of the piston rod 6 passes through the upper end cover 3 .

[0018] as attached figure 1 As shown, a suction hole 7 and a discharge hole 8 are respectively provided on the lower end cover 4 of the pump body.

[0019] as attached figure 1 As shown, the suction hole 7 is connected to the oil storage chamber 1 through a pipeline, and a first one-way valve 9 is provided on the connecting pipeline, and the discharge hole 8 is connected to the fuel injection pipe 10 through a pipeline, and in this connection A second one-way valve 11 is provid...

Embodiment 2

[0028] This embodiment is further improved on the basis of Embodiment 1.

[0029] In the lubricating oil filling device provided in Embodiment 1, when the piston rod 6 moves up and down with the movement of the slider, the oil injection pipe 10 continues to inject oil, and in some application environments, it is not required The continuous filling of lubricating oil requires that the lubricating oil form the effect of time-sharing filling, that is, although the piston rod 6 is in a state of continuous reciprocating motion, the oil injection pipe 10 does not spray oil continuously, but sprays oil in a controlled time-sharing manner. . In order to achieve the above effects, in this embodiment, as attached figure 2 As shown, on the basis of the lubricating oil filling device provided in Embodiment 1, a branch pipe 19 is provided on the pipeline connecting the discharge hole 8 and the oil injection pipe 10, and the branch pipe 19 connects the connected pipeline with the oil stor...

Embodiment 3

[0031] In this embodiment, the driving device at the top of the piston rod 6 provided in Embodiment 1 is further limited.

[0032] as attached image 3 As shown, in this embodiment, the driving device at the top of the piston rod 6 can be an electric driving device. In this embodiment, the electric driving device is driven by an electric push rod 22. After the electric push rod 22 is used for driving, The support spring 14 in Embodiment 1 can be removed, and the timing control of lubricating oil injection can also be realized by controlling the action interval of the electric push rod 22 .

[0033] Of course, in addition to the electric push rod provided in this embodiment, the electric drive device can also use a motor to drive the screw or other electric drive devices that can drive the piston to move up and down, which will not be described in detail here.

[0034] The use of an electric drive device can separate the drive device from moving parts such as sliding blocks, w...

Abstract

Especially, for solving the technical problems existing in a lubricating oil filling process in a current mechanical motion process, the invention provides an automatic lubricating oil filling device.The automatic lubricating oil filling device comprises an oil storage chamber and is characterized by also comprising a suction pump; the suction pump comprises a pump body; a piston is arranged inside the pump body and is connected with a piston rod; the top of the piston rod penetrates through an upper end cover; a lower end cover of the pump body is separately provided with a sucking hole anda discharging hole; the sucking hole is connected with the oil storage chamber through a pipeline, and the connecting pipeline is provided with a first one-way valve; the discharging hole is connectedwith an oil spraying pipe through the pipeline, and the connecting pipeline is provided with a second one-way valve; the first one-way valve and the second one-way valve are characterized in that each one-way valve is opened towards a side which is relatively low in pressure when the two sides of the corresponding valve body has a pressure difference; and the top of the piston rod is connected with a driving device. The automatic lubricating oil filling device is reasonable in structure, stable in oil supply and capable of guaranteeing the real-time lubrication needs of components.

Description

technical field [0001] In particular, the present invention relates to a device for automatically filling lubricating oil during lubricating operation during mechanical movement. Background technique [0002] In the process of mechanical movement, the frictional movement between parts needs to be lubricated with lubricating oil. Taking the action of the linear guide as an example, the function of the linear guide is to support and guide the moving parts, and to make a reciprocating linear motion in a given direction. Among them, the guide rail and the linear shaft are one of the core components of the equipment, and their function is to guide and support. In order to ensure that the machine has high machining accuracy, its guide rails and straight lines are required to have high guiding accuracy and good motion stability. In order to ensure the guiding accuracy and the stability of the movement, the guide rail is required to have good lubricity, and lubricating oil needs t...
