Double-spindle automatic drilling and tapping machine

Abstract

The invention discloses a double-spindle automatic drilling and tapping machine. The double-spindle automatic drilling and tapping machine is characterized in that a drilling and tapping power head comprises two spindles, a first spindle is connected with a lower output end of a first speed changing box, a second spindle is connected with a lower output end of a second speed changing box, the first speed changing box and the second speed changing box are movably arranged up and down in a power head tank body, one side of the first speed changing box is fixedly connected with a first rack, the first rack is in meshing transmission with a first gear, one side of the second speed changing box is fixedly connected with a second gear, the second rack is in meshing transmission with the second gear, the first gear and the second gear idly sheathe a handle shaft, the handle shaft is rotatably arranged in the power head tank body, and a declutchable locking hand wheel and a gear-shifting hand wheel are respectively arranged at the two ends of the handle shaft. The double-spindle automatic drilling and tapping machine has the advantages that a double-spindle design is adopted, drilling and tapping processing is facilitated, the working efficiency is improved, an automatic drilling and tapping technology is originally designed, and a function of protecting a hole from being drilled through is realized.

Description

technical field [0001] The invention relates to an automatic drilling and tapping machine for drilling and tapping. Background technique [0002] Compared with desktop hole processing equipment, cantilever hole processing equipment has the advantages of large processing range and strong processing operation flexibility. The feature of the cantilever hole processing equipment is that the hole position can be arbitrarily selected within the range of 360°, which can be used for hole processing of large-area workpieces. The applicant applied for the patent No. 201310544662.0 on November 7, 2013 and the invention patent named "cantilever type small diameter hole drilling equipment". Heavy technology, but can not realize automatic drilling and tapping; In addition, in the prior art, all kinds of hole processing equipment are single-spindle design, drilling is equipped with a drill bit, and tapping is equipped with a tap, which is not convenient for drilling and tapping. Low wo...

The applicant applied for the patent No. 201310544662.0 on November 7, 2013 and the invention patent named "cantilever type small diameter hole drilling equipment". Heavy technology, but can not realize automatic drilling and tapping; In addition, in the prior art, all kinds of hole processing equipment are single-spindle design, drilling is equipped with a drill bit, and tapping is equipped with a tap, which is not convenient for drilling and tapping. Low work efficiency; in addition, like other drilling equipment, when drilling through holes, the drill bit will be very prone to breakage due to sudden changes in the force of the drill bit when drilling through the hole, resulting in poor drilling quality and low drilling efficiency.
