Multi-station drilling machine

Abstract

The invention discloses a multi-station drilling machine. The multi-station drilling machine includes a machine frame, a rotary table, a rotary table driving mechanism, four workpiece positioning mechanisms uniformly distributed and arranged on the front part, the rear part, the left part and the right part of the rotary table and drilling mechanisms separately arranged on both sides of each groupof workpiece positioning mechanisms. The drilling mechanisms include drilling frames horizontally and slidably arranged on both sides of the workpiece positioning mechanisms symmetrically, a plurality of drilling sliding blocks separately and slidably arranged on the drilling frames on each side in the horizontal direction, drilling heads rotatably arranged on the drilling sliding blocks, drilling motors driving the drilling heads to rotate, displacement mechanisms driving the drilling frames to slide and driving cylinders driving the drilling sliding blocks to slide. The displacement mechanisms include first lead screws and second lead screws rotatably arranged on the machine frame and motors driving the rotation of the first lead screws. First screw sleeves matched with the lead screwsare fixed to the drilling frames on one side, and second screw sleeves matched with the second lead screws are fixed to the drilling frames on the other side. Transmission gears are fixedly arranged on the end parts of the lead screws, and second transmission gears meshing with the transmission gears are fixedly arranged on the end parts of the second lead screws.

Description

technical field [0001] The invention relates to the field of automatic drilling, in particular to a multi-station drilling machine. Background technique [0002] At present, when drilling workpieces, especially for workpieces that need to be drilled in a variety of sizes, quantities, and positions, it is necessary to continuously replace different types of drill bits and adjust the position and number of drill bits, resulting in low processing efficiency. Contents of the invention [0003] The object of the present invention is to overcome the defects existing in the prior art, and provide a multi-station drilling machine with high degree of automation, high efficiency and greatly reduced production cost. [0004] In order to achieve the above technical effects, the technical solution of the present invention is: a multi-station drilling machine, including a frame, a turntable arranged on the frame for vertical rotation, and a The turntable driving mechanism that drives t...
