Caterpillar CP is in a state of being separated is free from the slide portion 123 of the transfer member 120.

As such, when the caterpillar CP is in a prone state on the processing plate 110 of the base 100, the transfer member 120 is supplied with power to drive the feed feeder 125, and the caterpillar CP contacted thereto is transferred. The feeder 125 moves at a predetermined interval, and stops again when the fueling position A is reached to repeatedly perform the operation of fixing the upper surface of the bush B and the side of the link link L of the caterpillar CP. do.

According to the above configuration, the caterpillar is moved along the slide portion of the base, and when reaching the lubrication position serves to stop the state to match the hole of the pin of the connecting link, the lubrication member is in close contact with the caterpillar in the stopped state By lubricating and inserting the plug alternately, this lubrication operation is repeated to complete the lubrication work on the assembled caterpillar pin.

The nozzle hole 351 is in a state coinciding with the center position of the hole H of the pin P assembled in the caterpillar CP. If the standard of the caterpillar CP is different, the hole H center position of the pin P is different. The position of the nozzle hole 351 should also change as much as the changed size. In this case, the front and rear adjustment shaft 371, the left and right adjustment shaft 373, and the vertical adjustment shaft 375 of the feed adjusting member 370 are adjusted. By the tub tail structure of the lower feed control member 370 and the lead screw structure, the position of the lubrication member 300 is adjusted on the processing plate 110 in the horizontal direction, the front and rear directions, and the up and down direction so that the pins of the caterpillar CP ( It can be adjusted to position P).

According to the present invention, when the assembled caterpillar is transported to the fueling position, the operation of inserting the plug to stop the oiling operation and oil from leaking is automatically performed, and the operation of transferring the next pin to the oiling position of the nozzle after oiling is performed. Because it is made repeatedly, the working environment of the work site can be kept clean, the state of oiling is also made clean in the caterpillar, and the amount of oil injection and the insertion state of the plug are made uniform throughout the product. It is easier to manage.

As described above, the present invention moves the assembled caterpillar at a predetermined interval while injecting oil into the hole of the bushing fixing pin and inserting a stopper in order to prevent leakage. It is possible to supply the product efficiently, and the lubricant is not leaked around the lubrication position when the lubricant is injected, and the surroundings of the workplace are kept clean.At the same time, the insertion of the plug inserts the driving force of the cylinder. By facilitating standard management, there is an advantage of improving productivity as well as quality.
