The invention discloses a boring bar guide device. The boring bar guide device comprises milling shafts; each milling shaft is provided with a long guide key; and the ends of the milling shafts are provided with two guide end face keys which can increase the guide length. The boring bar guide device has a reasonable structure and greatly increases the guide length so as to ensure the linear movement accuracy of a boring bar.
Description
technical field [0001] The invention relates to a boring bar guide device for a boring machine. Background technique [0002] In the boring machine, the boring bar needs to make a linear feed motion in the Z axis along the milling axis. The milling axis generally transmits the linear feed motion through two long guide keys. The longer the long guide key, the straight line it can transmit The higher the motion accuracy, but due to its structural constraints, the length of the long guide key is limited to a certain extent. Contents of the invention [0003] The object of the present invention is to provide a boring bar guide device with reasonable structure and ensuring the linear motion precision of the boring bar. [0004] Technical solution of the present invention is: [0005] A boring bar guiding device includes a milling shaft on which long guiding keys are mounted, and is characterized in that two guiding end face keys for increasing the guiding length are arranged ...
