[0025] In the above structure, the lubricating oil is stored in the oiling box 3. Before lubricating the linear guide 1, the oil outlet 303 is sealed by the sealing component 7, and the oil plug 6 is opened to add the lubricating oil into the oil storage tank 302 in the oiling box 3. When lubricating the linear guide 1, the sealing component 7 is opened to connect the oil outlet 303 with the oil storage tank 302, and the lubricating oil is discharged from the oil outlet 303 through the oiling component 5. The displacement of the lubricating oil can be controlled by the oiling component 5, and the slider base 2 is started to drive the oiling box 3 to slide on the linear guide 1 to achieve lubrication of the linear guide 1.

[0026] The specific structures of the refueling assembly 5 and the sealing assembly 7 are as follows:

[0027] Combined with Figure 2 The refueling assembly 5 includes a mounting groove 304 provided at the lower end of the oil storage tank 302, a motor 8 is installed in the mounting groove 304, and the upper output end of the motor 8 is connected to a threaded rod 9 passing through the bottom wall of the mounting groove 304, and the upper end of the threaded rod 9 is installed with a support frame 10 connected to the mounting groove 304, so that the threaded rod 9 can rotate stably, and a piston 11 is slidably connected in the oil storage tank 302 through which the threaded rod 9 passes and is threadedly connected.

[0028] Through the above structure, when the refueling assembly 5 is in use, the motor 8 is started to drive the threaded rod 9 to rotate. Since the oil storage tank 302 and the piston 11 are rectangular, the piston 11 threadedly connected to the threaded rod 9 moves longitudinally in the oil storage tank 302, which is convenient for discharging the lubricating oil in the oil storage tank 302; the motor 8 is connected to an external control system, and the control system controls the rotation speed, rotation time and other conditions of the motor 8, thereby controlling the downward movement speed and downward movement amount of the piston 11, and then controlling the discharge speed and discharge amount of the lubricating oil to prevent waste of the lubricating oil.

[0030] Combined with Figure 1-2 A cover plate 14 is installed at the upper end of the oil storage tank 302, and a cover plate 2 15 is installed at the front end of the installation tank 304, so as to facilitate maintenance of the oil storage tank 302 and the motor 8 in the installation tank 304.

[0031] Combined with Figure 1-2 The sealing assembly 7 includes a rectangular tube 16 slidably connected to the lower end of the oil storage tank 302, the threaded rod 9 passes through the inner hole of the rectangular tube 16, and a plurality of sealing plug covers 17 cooperating with the oil outlet hole 303 are fixed on one side of the rectangular tube 16.

The threaded rod 18 passes through the side wall of the oil storage tank 302 and is threadedly connected thereto, and a knob 19 is fixed to the end of the threaded rod 18.

[0032] With the above structure, when the sealing assembly 7 is used, the threaded rod 18 is rotated by turning the knob 19, so that the threaded rod 18 drives the rectangular tube 16 and the sealing plug cover 17 to move horizontally, and the sealing plug cover 17 starts the plugging and sealing function of the oil outlet 303.

[0033] The specific usage is as follows:

[0034] The initial state of the oil outlet 303 is that it is blocked and sealed by the sealing plug cover 17. The oil plug 6 is opened to add lubricating oil into the oil storage tank 302 in the oil filling box 3. When the linear guide 1 needs to be lubricated, the sealing component 7 is used to rotate the knob 19 to rotate the threaded rod 18, so that the threaded rod 18 drives the rectangular cylinder 16 and the sealing plug cover 17 to move horizontally, so that the oil outlet 303 is opened; the oil filling component 5 is used to start the motor 8 to drive the threaded rod 9 to rotate. Since the oil storage tank 302 and the piston 11 are rectangular, the threaded connection with the threaded rod 9 is The connected piston 11 moves longitudinally in the oil storage tank 302, so as to discharge the lubricating oil in the oil storage tank 302 through the oil outlet hole 303; the motor 8 is connected to the external control system, and the rotation speed, rotation time and other conditions of the motor 8 are controlled by the control system, thereby controlling the downward movement of the piston 11, and then controlling the discharge speed and discharge amount of the lubricating oil; at this time, starting the slider base 2 drives the oil box 3 to slide on the linear guide 1, so as to realize the lubrication of the linear guide 1; after the lubrication is completed, the sealing plug cover 17 is blocked and sealed by the sealing component 7.

[0035] The lubricating oil is stored in the oiling box 3, and when needed, the linear guide rail 1 can be lubricated by simply starting the oiling assembly 5, which is convenient to use; the amount of lubricating oil added is controlled by controlling the oiling assembly 5 to prevent waste of lubricating oil.

[0036] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
