AI Technical Summary
Traditional gantry milling machine fixtures are difficult to adjust the clamping angle when machining irregularly shaped parts for mining machinery, resulting in uneven clamping and affecting machining quality and accuracy.
A milling machine fixture for mining machinery manufacturing was designed, comprising a worktable, a limiting groove, a fixture structure, a top-mounted fixture mechanism, and a connecting structure. Through components such as inclined surfaces, limiting guide rails, top clamping blocks, and adjusting bolts, the clamping position and angle can be flexibly adjusted to prevent slippage and enhance the positioning effect.
It improves the ease of clamping and processing quality of irregularly shaped parts in mining machinery, reduces processing vibration, improves surface quality and dimensional accuracy, and extends the service life of the drive mechanism.
