AI Technical Summary
The existing oil-cooled gantry gear heads lack the structure to limit the oil outlet pipe, which leads to the problem of oil leakage when the body vibrates.
An oil-cooled gantry gear head is designed, and a limiting assembly is used to include two clamping plates with mirror distribution. The clamping plate is slidably installed on one side of the body and can be in contact with the surface of the oil outlet pipe. Through the cooperation of the bidirectional screw and the knob, the clamping limit of the oil outlet pipe is achieved.
It effectively prevents the oil outlet pipe from loosening when the body vibrates, avoiding oil leakage. At the same time, by installing a filter in the gas nozzle, impurities in the oil liquid are filtered out to prevent oil passage from being blocked.
