[0021] The following will describe in detail the preferred embodiments of the present utility model in conjunction with the accompanying drawings.

[0022] As Figures 1 - 4 shown, a cross-roller guide for a slide cylinder includes a movable slide 1, which is movably arranged above a fixed slide 2. A support protrusion 3 is fixed on the top surface of the fixed slide 2, and a PLC controller is fixed on the right side of the fixed slide 2. First V-shaped guides 4 are respectively detachably arranged on the left and right outer walls of the support protrusion 3. Second V-shaped guides 5 are respectively fixed on the left and right inner walls of the movable slide 1. Roller retainers 6 are respectively arranged between the two first V-shaped guides 4 and the two second V-shaped guides 5. An oil storage cavity 7 is arranged inside the movable slide 1. An oil inlet 8 is opened on the bottom surface of the oil storage cavity 7, and an oil inlet pipe 9 is fixed inside the oil inlet 8. Installation grooves 10 are respectively opened on the left and right inner walls of the oil storage cavity 7. Oil injection holes 11 are respectively opened on the outer sides of the inner walls of the two installation grooves 10. Miniature oil pumps 12 are respectively fixed inside the two installation grooves 10. The miniature oil pumps 12 are electrically connected to the PLC controller. Connecting pipes 13 are respectively fixed on the input ends of the two miniature oil pumps 12. Delivery pipes 14 are respectively fixed on the output ends of the two miniature oil pumps 12. The two delivery pipes 14 are respectively fixed in the two oil injection holes 11. Nozzles 15 are respectively fixed on the bottom ends of the two delivery pipes 14.

[0023] In use, the staff first installs the fixed slide 2 in the working area, then installs the first V-shaped guides 4 on both sides of the support protrusion 3 respectively, injects lubricating oil into the oil storage cavity 7 through the oil inlet 8 and the oil inlet pipe 9, then installs the second V-shaped guides 5 on both sides of the inner wall of the movable slide 1, places the movable slide 1 on the top of the fixed slide 2, and then inserts the roller retainers 6 between the first V-shaped guides 4 and the second V-shaped guides 5 to complete the assembly. Secondly, the device starts to work. During the working process, the movable slide 1 moves continuously following the limiting object. As the device starts, the PLC controller automatically activates the miniature oil pumps 12 according to the preset time interval. The miniature oil pumps 12 suck the lubricating oil from the oil storage cavity 7 through the connecting pipes 13, and then deliver the lubricating oil to the nozzles 15 through the delivery pipes 14, realizing precise and uniform lubrication operation, ensuring continuous lubrication of the roller retainers 6 during the working process, effectively extending the service life of the device, and improving the operation efficiency.

[0024] As Figure 2 and Figure 3 shown, a connection hole 16 is opened on the top surface of the oil storage cavity 7, and a liquid level sensor 17 is fixed inside the connection hole 16. The liquid level sensor 17 is electrically connected to the PLC controller.

[0025] In use, as the equipment is used, the amount of lubricating oil in the oil storage chamber 7 gradually decreases. The liquid level sensor 17 can accurately monitor this change, ensuring accurate control of the amount of lubricating oil and avoiding equipment failures caused by lack of oil.

[0026] As Figures 1 - 4 shown, an alarm 18 is fixed to the front side of the fixed slide table 2. The alarm 18 is electrically connected to the PLC controller, and a sealing plug 19 is provided inside the oil inlet pipe 9.

[0027] In use, when the PLC controller receives the low oil level signal sent by the liquid level sensor 17, it will immediately activate the alarm 18 on the front side of the fixed slide table 2. The alarm 18 will emit obvious sound and light signals to attract the attention of the staff, reminding them to immediately take measures to replenish the lubricating oil, ensuring that the staff can know the insufficient lubricating oil situation in the first time. The sealing plug 19 provided inside the oil inlet pipe 9 is tightly screwed after the lubricating oil is injected, effectively preventing the leakage of the lubricating oil and the entry of external impurities, not only ensuring the cleanliness inside the oil storage chamber 7, but also avoiding the waste of the lubricating oil.

Bolts 23 are respectively threadedly connected inside the two threaded holes 22. The threaded ends of the two bolts 23 are respectively threadedly connected to the inside of the two threaded grooves 20. Positioning grooves 24 are respectively formed on the left side and the right side of the support protrusion 3. Positioning blocks 25 are respectively fixed to the inner sides of the two first V-shaped guide rails 4. The two positioning grooves 24 respectively position the two positioning blocks 25.

[0029] In use, by matching the threaded holes 22 on the fixing plate 21 with the threaded grooves 20 on the support protrusion 3 and using the bolts 23 for fastening connection, the staff can fix the first V-shaped guide rail 4 on the support protrusion 3, which not only simplifies the installation process, but also improves the stability and reliability of the first V-shaped guide rail 4. The positioning grooves 24 on the support protrusion 3 are matched with the positioning blocks 25 on the inner side of the first V-shaped guide rail 4 to achieve the precise positioning of the first V-shaped guide rail 4, which not only simplifies the installation process of the first V-shaped guide rail 4, but also improves the alignment accuracy between the first V-shaped guide rail 4 and the support protrusion 3, ensuring the overall stability and operation effect of the equipment.
