Automatic drilling machine for locking dog

Abstract

An automatic drilling machine for a locking dog comprises a tapping and drilling device, wherein the tapping and drilling device comprises a machine base, a stand column is fixed at one end of the machine base, a spindle box is fixed at the top of the stand column, a spindle is fixed to the spindle box and driven by a motor and shifts vertically through adjustment of a feeding handle, and a drill bit is fixed to the spindle; a bed frame is fixed to a work table of the machine base, a platform is arranged at the top of the bed frame, a locking dog feeding device and a locking dog clamping device are fixed to the platform, a press rod is fixed to the spindle of the tapping and drilling device and matched with an ejector rod in position, and a flange matched with a sliding block is fixed to the surface of a rotating disc with a shank. The automatic drilling machine for the locking dog is reasonable and ingenious in structural design and worthy of application and popularization.

Description

technical field [0001] The invention relates to a processing machine, in particular to a bolt automatic drilling machine for bolt holes. Background technique [0002] The lock tongue is an important part of the mechanical door lock. The opening and closing of the door lock is controlled by the expansion and contraction of the lock tongue. However, the key step to control the expansion and contraction of the lock tongue is to drill holes on the side of the lock tongue, and then fix the upper pull rod. The pull rod is telescopic to control the expansion and contraction of the bolt, especially for the square bolt of the 556 ordinary exterior door lock, the bolt hole drilling is a key step in the door lock manufacturing process; the drilling of this square bolt on the market is still limited. Often stay at the original lock tongue and manually twist the clamp block to clamp the lock tongue through simple clamping, and then manually rotate the feed handle on the drilling machine....

[0002] The lock tongue is an important part of the mechanical door lock. The opening and closing of the door lock to the door is controlled by the expansion and contraction of the lock tongue. However, the key step to control the expansion and contraction of the lock tongue is to drill holes on the side of the lock tongue, and then fix the upper pull rod. The pull rod is telescopic to control the expansion and contraction of the bolt, especially for the square bolt of the 556 ordinary exterior door lock, the bolt hole drilling is a key step in the door lock manufacturing process; the drilling of this square bolt on the market is still limited. Often stay at the original lock tongue and manually twist the clamp block to clamp the lock tongue through simple clamping, and then manually rotate the feed handle on the drilling machine. After the hole is drilled, manually loosen the simple clamp and take out the drilled hole. The lock tongue, this way of drilling the lock tongue is not only low in production efficiency, but also difficult to guarantee the machining accuracy
