Problems solved by technology
The downward force for the drilling head is realized by pulling the drilling control handle, and the rack and pinion transmission structure is used in the middle. The fatal shortcoming of the above structure is that it cannot provide small Stable downward force, the handle does not feel light and forceful when pulling the handle. As a result, the downward force of the drilling head is uncontrollable during drilling. Excessive force can easily cause small-diameter drills to break, so it is not suitable for drilling. Drilling holes with a diameter of 0.5-3mm
Also have, the small-diameter hole drilling and tapping equipment of prior art, its drilling, tapping operation can not realize quick conversion

The invention discloses a control handle part of small-diameter hole boring threading equipment. The control handle part comprises a boring control handle, a fixation plate, a grooved pulley, a slide block and a clutch disc, wherein the fixation plate is fixedly installed on the side surface of a machine head cover; the grooved pulley is rotationally arranged in a grooved pulley hole arranged on the fixation plate; the grooved pulley is connected with the boring control handle through a handle shaft; the fixation plate is provided with a vertical chute; the vertical chute is arranged along the direction of the tangent of the grooved pulley hole; the slide block slides up and down in the vertical chute; the side surface of the slide block is provided with an insertion part; the bottom of the slide block is connected with the upper end of a steel wire; the lower end of the steel wire is connected with the grooved pulley in a winding manner; the clutch disc is rotationally arranged at the top of a boring threading power head installation seat; and the side surface of the clutch disc is provided with a clutch groove. The greatest attraction of the invention is the innovative design of a brand new control handle structure which is suitable for boring and threading of a small hole with a diameter of 0.5-3 mm. Besides, the control handle part provided by the invention can realize rapid conversion between boring operation and threading operation.
Description
technical field [0001] The invention relates to a small-diameter hole drilling and tapping device for drilling and tapping small holes with a diameter of 0.5-3mm, in particular to a control handle part of the small-diameter hole drilling and tapping device. Background technique [0002] For small-diameter hole drilling and tapping equipment for drilling and tapping small holes with a diameter of 0.5-3mm, the key point in drilling is to ensure that the drilling power head has a small and stable downward pressure and return force. , so that the small diameter drill bit will not break easily. The downward force for the drilling head is realized by pulling the drilling control handle, and the rack and pinion transmission structure is used in the middle. The fatal shortcoming of the above structure is that it cannot provide small Stable downward force, the handle does not feel light and forceful when pulling the handle. As a result, the downward force of the drill...
