Description

Technical Field

[0001] The utility model relates to the technical field of piston rod production equipment, in particular to an oiling device for piston rod production. Background Art

[0002] The piston rod is the rod body that telescopes and moves in the hydraulic cylinder or pneumatic cylinder. After the piston rod is processed, it will be oiled. After oiling, a layer of oil film will be covered on the piston rod. The oiling has the effect of preventing rust, avoiding oxidation of the piston rod, and keeping the piston rod in a good condition.

[0003] Small and shorter piston rods are directly immersed in the oil pool for the oiling process. However, it is difficult for longer piston rods to match such a long oil pool. Most of the time, a nozzle is used to spray oil, and then personnel manually assist in expanding the coating range. It is difficult for personnel to ensure the uniformity of coating. In order to cover the coating range, more oil is needed to adapt to manual coating, and the amount of oil used is large. Summary of the invention

[0004] The disclosed embodiment relates to an oiling device for piston rod production, wherein an oil spraying rack sprays oil on the piston rod, and an oil-distributing scraper rotates circumferentially with the oiling ring rack to evenly apply oil to the surface of the piston rod. The coating thickness is more consistent and even, reducing the amount of oil used, ensuring the evenness of the oil on the surface of the piston rod, and eliminating the need for personnel to assist in the coating.

[0012] The utility model provides an oiling device for piston rod production, which has the following beneficial effects:

[0013] The oil spray rack sprays oil on the piston rod, and the oil scraper rotates in a circular direction with the oiling ring rack to evenly apply oil on the surface of the piston rod, thereby reducing the amount of oil used, ensuring the uniformity of oil on the surface of the piston rod and eliminating the need for personnel to assist in applying the oil.

[0029] In the disclosed embodiment, the side screw 102 and the telescopic block 103 are threadedly connected. When the side screw 102 rotates, the telescopic block 103 moves axially along the thread of the side screw 102, and the oil scraper 104 moves and adjusts its position along with the telescopic block 103. The oil scraper 104 moves outward to adapt to a piston rod with a larger diameter, and moves toward the center to adapt to a piston rod with a smaller diameter.

[0030] In the disclosed embodiment, the displacement screw 202 is screwed to the lower part of the fuel injection rack 2, the oil tank 205 is fixed to the lower part of the main frame 3, the upper lifting rack 201 is vertically slidably connected to the main frame 3, and the two fuel injection racks 2 are horizontally moved toward each other to adjust the spacing through the rotation of the displacement screw 202 to adapt to piston rods of different diameters.

[0031] In the embodiment of the present disclosure, the upper lifting frame 201 and the side lifting frame 302 are both threadedly connected with the lifting screw 301. The upper lifting frame 201 and the side lifting frame 302 move axially along the thread of the lifting screw 301.

The oil scraper 104 moves outward to adapt to a piston rod with a larger diameter. The oil scraper 104 is adjusted according to piston rods of different diameters to maintain fit, thereby improving compatibility with piston rods of different diameters. The two spray racks 2 move horizontally oppositely to adjust the spacing through the rotation of the displacement screw 202, and adjust and match according to piston rods of different diameters. The spray rack 2 adjusts its height along with the upper lifting rack 201, and the lifting and adjusting height is always in the middle position of the piston rod for spraying oil, so as to avoid the situation where the spray rack 2 is higher or lower than the piston rod, causing the oil sprayed by the spray rack 2 to spray to the upper and lower outsides of the piston rod, and to avoid the situation where the oil is not sprayed to the piston rod and caused waste. The side lifting bracket 302 and the inner support roller 303 adjust their heights so that the piston rod transported at the top of the inner support roller 303 is always aligned with the center of the oiling ring rack 1.
