[0030] Reference Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment of this utility model, an automatically oiling linear slide rail device is disclosed, comprising:

[0031] The slide body 1 is connected to multiple sliders. The interior of the slide body 1 is provided with an oil storage chamber, a first oil passage 14 and an air passage. The oil storage chamber is provided with a push piston 9, which divides the oil storage chamber into a first cavity 111 and a second cavity 112. The first oil passage 14, the first cavity 111 and the oil hole of the slider are connected. The second cavity 112 is connected to the air passage. The slide body 1 is also provided with an oil inlet 141 connected to the first oil passage 14 and an air inlet connected to the air passage.

[0032] The linear slide rail device with automatic oil injection described in this embodiment overcomes the problem of limited oil injection operation space by setting a first oil passage 14 connecting the oil hole of the slide block and an oil storage chamber in the slide body 1. The lubricating oil in the oil storage chamber can be injected into the oil hole of the slide block through the first oil passage 14 to lubricate the circulating steel balls. The lubricating oil is injected into the first cavity 111 through the oil injection port 141 and stored. When it is necessary to lubricate the circulating steel balls of the slide block, the piston 9 can be moved by periodically pressurizing the air inlet to squeeze the lubricating oil into the slide block. This realizes quantitative and periodic automatic oil injection, eliminating the need for frequent manual oil injection and improving the problem of low oil injection efficiency.

[0033] Reference Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment of this utility model, connecting blocks 3 are connected to both sides of the slide body 1. The connecting block 3 is provided with a built-in second oil channel 31, an oil outlet hole and an oil inlet hole 33 communicating with the second oil channel 31. The two sides of the connecting block 3 respectively abut against the two sliders. The connecting block 3 abuts against the oil outlet holes on both sides of the sliders. The oil outlet holes are connected to the oil holes. The oil inlet hole 33 is connected to the first oil channel 14. The connecting block 3 serves as an oil transfer station to realize the diversion of oil from a single oil channel to multiple sliders.

[0034] Reference Figure 2 As shown, in one embodiment of the present invention, two sliders and a connecting block 3 are connected to each side of the slide body 1. The connecting block 3 is disposed between the two sliders. The two sliders located on the same side are marked as the first slider 2a and the second slider 2b. The two oil outlet holes located on both sides of the connecting block 3 are marked as the first oil outlet 34 and the second oil outlet 32. The first oil outlet 34 is connected to the oil hole 211 of the first slider, and the second oil outlet 32 ​​is connected to the oil hole 2b1 of the second slider 2b.

[0035] Reference Figure 3 As shown, in one embodiment of this utility model, the oil storage cavity is configured as a cylindrical cavity extending along the sliding direction of the slider body 1. The sum of the volumes of the first cavity 111 and the second cavity 112 is fixed, but as the piston 9 moves, the volumes of the first cavity 111 and the second cavity 112 change dynamically. When the first cavity 111 is filled with lubricating oil, the volume of the first cavity 111 is equal to the volume of the oil storage cavity. When the second cavity 112 is filled with pressurized gas, the volume of the second cavity 112 is equal to the volume of the oil storage cavity. The two ends of the cylindrical cavity are respectively connected to the first oil passage 14 and the air passage. Therefore, the pressurized gas in the air passage can enter the first cavity 111 through one end of the oil storage cavity, and the lubricating oil in the oil passage can enter the second cavity 112 through the other end of the oil storage cavity.

[0036] Reference Figure 3 As shown, in one embodiment of the present invention, the oil storage chamber includes two sets symmetrically arranged on both sides of the first oil passage 14. Each set of oil storage chambers is composed of multiple oil storage chambers. The oil storage chambers located on both sides of the first oil passage 14 are symmetrically arranged. The air passage located in the slide body 1 includes a first air passage 13a and a second air passage 13b. The first air passage 13a is connected to the first set of oil storage chambers, and the second air passage 13b is connected to the second set of oil storage chambers.

[0037] Reference Figure 3 As shown, in one embodiment of the present invention, each group of oil storage chambers consists of four oil storage chambers, and the four oil storage chambers are distributed along the length direction of the first oil passage 14.

[0038] Reference Figure 3 As shown, in one embodiment of the present invention, the first air passage 13a extends through to one side of the slide body 1 and forms a first air inlet 131, which is used to inject pressurized gas into the first air passage 13a; the second air passage 13b extends through to one side of the slide body 1 and forms a second air inlet 132, which is used to inject pressurized gas into the second air passage 13b.

[0039] Reference Figure 1 As shown, in one embodiment of this utility model, the first inflation port 131 is provided with a three-way connector 4, and the second inflation port 132 is provided with a straight connector 5. One straight end of the three-way connector 4 is connected to the input end of the straight connector 5 through an air pipe. After the external pressurized gas enters one straight end of the three-way connector 4, it flows to the first air passage 13a and the straight connector 5 respectively.

[0040] In one embodiment of this utility model, a pressurizing component (not shown) is also included on the slide body 1, and a solenoid valve (not shown) for controlling the opening and closing of the air passage of the pressurizing component. The pressurizing component is capable of generating pressurized gas, and the solenoid valve is controlled by an external PLC control program. The output end of the pressurizing component is connected to a straight end of the three-way connector 4 through an air pipe. Since the pressurizing component is set on the slide body 1, the pressurized gas can directly enter the three-way connector 4 through the air pipe without the need for frequent machine shutdowns to disassemble and connect the air pipe.

[0041] Reference Figure 3 As shown, in one embodiment of the present invention, the oil storage cavity extends to one side of the slide body 1 and forms an outlet 18, which facilitates the installation and maintenance of the push piston 9.

[0042] Reference Figure 3 As shown, in one embodiment of the present invention, the first oil passage 14 extends through to one side of the slide body 1 and forms an oil inlet 141. Lubricating oil enters the oil passage through the oil inlet 141. Furthermore, the oil inlet 141 is provided with a connector 6 that can be connected to an oil pipe.

[0043] Reference Figure 3 As shown, in one embodiment of the present invention, the slide body 1 is further provided with a first connecting hole 15 and a second connecting hole 15. The first oil passage 14 is connected to the oil inlet 33 of the first connecting block 3 through the first connecting hole 15, and is connected to the oil inlet 33 of the second connecting block 3 through the second connecting hole 16.

[0044] Reference Figure 3As shown, in one embodiment of the present invention, the slide body 1 is further provided with four connecting holes 17. Each connecting hole 17 is used to connect the first oil passage 14 and two oil storage chambers symmetrically arranged on both sides of the first oil passage 14. The lubricating oil in the oil passage enters the oil storage chambers on both sides through the connecting hole 17. Similarly, the lubricating oil in the oil storage chambers on both sides can enter the oil passage through the connecting hole 17. The two oil storage chambers connected by the connecting hole 17 are marked as the first oil storage chamber 11 and the second oil storage chamber 12.

[0045] Reference Figure 1 As shown, in one embodiment of this utility model, a first slide rail 7 and a second slide rail 8 are also included. The first slider 2a and the second slider 2b located on one side of the slide body 1 are both slidably connected to the first slide rail 7, and the two sliders located on the other side of the slide body 1 are both slidably connected to the second slide rail 8.

[0046] Reference Figure 2 As shown, in one embodiment of this utility model, the outlet 18 is provided with an internal thread, and the outlet 18 is threadedly connected to a sealing member 10. The sealing member 10 is used to seal the outlet 18 to ensure stable air pressure in the air passage; the sealing member 10 can also limit the movement of the pushing piston 9.

[0047] In one embodiment of this utility model, the sealing member 10 is provided as a stop screw, one end of which can press against the push piston 9.

[0048] Reference Figure 7 As shown, in one embodiment of this utility model, each connecting block 3 is also provided with a threaded hole 35 communicating with the second oil passage 31. When the oil storage chamber is filled with oil, the threaded hole 35 can be screwed into the bolt 36 to temporarily block the second oil passage 31, so as to prevent the lubricating oil from directly entering the first slider 2a and the second slider 2b from the second oil passage 31. After the oil storage chamber is filled with oil, the bolt 36 can be removed to restore unobstructed flow.

[0049] The working principle of the automatically oiling linear slide rail device described in this utility model is as follows:

[0050] A predetermined amount of lubricating oil is injected into the first cavity 111 through interface 6. The PLC control program periodically controls the solenoid valve to open the air passage of the pressurizing component. When the slider needs lubrication, the solenoid valve opens the air passage of the pressurizing component, and the pressurized gas of the pressurizing component is filled into the three-way connector 4 through the air pipe. The pressurized gas enters the first air passage 13a and the second air passage 13b from the three-way connector 4 respectively, and pushes the pistons 9 in the two sets of oil storage chambers to move. The lubricating oil in the first cavity 111 is squeezed into the first oil passage 14 by the pistons 9 and enters the second oil passage 31 from the oil inlet 33. Finally, the lubricating oil enters the oil holes of the sliders on both sides from the first oil outlet 34 and the second oil outlet 32 ​​respectively to lubricate the circulating steel balls, realizing automatic lubricating oil injection.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
