Pulse portable drill

Abstract

The invention relates to machining tools, in particular to an impulse type portable drill. The impulse type portable drill comprises a support, and a spindle is rotatably connected to the support; the spindle is sleeved with a driving bevel gear, and a driving disc is arranged on the support; the driving disc is rotatably connected with the support through a rotating shaft, and driving teeth are arranged on the edge of the driving disc; and the driving teeth are meshed with the bevel gear. A clutch mechanism is arranged on the rotating shaft, and a reverse mechanism is arranged between the rotating shaft and the driving bevel gear; a segment of impulse protrusions is arranged on the end face, close to the driving bevel gear, of the support, and an impulse protruding block is arranged on the end face, close to the support, of the driving bevel gear. The impulse type portable drill has the beneficial effects that reverse tool retracting of the impulse frequency can be achieved, the hand cranking direction is not required to be changed, and the stable hand cranking speed is ensured.

Description

technical field [0001] The invention relates to a processing tool, in particular to a pulse type portable drill. Background technique [0002] In an existing type of manual drilling tool, by shaking the drive disc, the drive teeth on the drive disc are used to drive the main shaft to rotate, and then the drill bit is driven to rotate to realize drilling. Waste chips are generated during the drilling process, and the waste chips are easy to block the drill bit. It is necessary to reverse the drill bit to retract the tool to discharge the waste chips out of the hole, and then continue drilling. However, when this type of manual drilling tool needs to reverse the drill bit to retract the tool and remove chips, the drill bit can only be reversed by shaking the drive disc in reverse. That is to say, the drive disk needs to rotate clockwise several times to drill holes, then counterclockwise several times to retract the tool to remove chips, and then rotate clockwise to drill hol...

AI Technical Summary

Problems solved by technology

During the drilling process, it is necessary to change the direction of the drive disc repeatedly, and the driving force of the hand drill comes from the human arm muscles. Frequent changes in the direction of the hand will result in different directions of force applied to the arm muscles and joints, which will easily cause the hand drill to deflect.

Moreover, the frequent changes of hand-cranking movements make the muscles unable to form muscle memory, resulting in unstable hand-cranking speed and affecting the quality and efficiency of drilling.
