Abstract

The invention discloses a drilling machine including a machine seat (4), a working table (6), a main shaft (13) and a drilling bit (15). The drilling machine is characterized in that the working table(6) is arranged on the middle of the top face of the machine seat (4), the back end face of the working table (6) is connected with a workpiece fixture (12); sliding rails (7) are arranged on the left and right sides of the working table (6) in a symmetrical mode, and grooves (16) are formed in the sliding rails; transmission screw rods (9) are arranged in the grooves (16), the transmission screwrods (9) abuts against a guiding seat (8) fixedly connected with a main shaft box (11) by screws and is connected with the sliding rail (7) in a movable mode, and is arranged above the transmission screw rods (9); and the main shaft (13) internally penetrates from the main shaft box (11).

Description

technical field [0001] The invention relates to hole processing equipment, in particular to a vertical double-head drilling machine tool suitable for processing holes for parts such as automobile connecting shafts and valves. Background technique [0002] At present, many mechanical parts such as connecting shafts and valves need to be processed with holes. The processing machine generally uses a single drill bit. During processing, the parts need to be rotated to drill the other side. The operation is cumbersome and time-consuming, and the accuracy cannot be guaranteed after rotation. It is also impossible to process in large quantities, so there is still room for improvement in hole processing. . Contents of the invention [0003] In order to solve the problems of low processing efficiency, poor machine tool stability, low precision, and inapplicability to mass production in the prior art, the purpose of the present invention is to provide a machine tool with high proce...
