Pulse impulsion manual drilling tool

Abstract

The invention relates to a machining tool, in particular to a pulse impulsion manual drilling tool. The pulse impulsion manual drilling tool comprises a support, and the support is rotatably connected with a spindle. 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 rotary shaft. The axis of the driving disc is perpendicular to the axis of the spindle, driving teeth are arranged on the edge of the driving disc, and the driving teeth and the bevel gear mesh. The spindle is in sliding connection with the support in the axial direction, and a pulse protrusion is arranged on the end face, close to the driving bevel gear, of the support. A pulse protruding block is arranged on the end face, close to the support, of the driving bevel gear, and the pulse protruding block and the driving bevel gear are eccentrically arranged. A pre-tightening spring is arranged at the end, far away from a drill bit, of the driving bevel gear. The pulse impulsion manual drilling tool has the beneficial effects that reverse tool retreating of pulse frequency can be achieved, the hand-rocking direction or movement does not need to be changed, it is guaranteed that the hand-rocking speed is fundamentally stable, and drilling quality and benefits are improved.

Description

technical field [0001] The invention relates to a processing tool, in particular to a pulse impact manual 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...

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.
