Pistol drill with distance measuring function

Abstract

The invention discloses a pistol drill with a distance measuring function. The pistol drill comprises a case, a trigger and a pistol drill motor, wherein the trigger is arranged on the case, the pistol drill motor is arranged in the case and is connected with a drilling bit, the trigger and the pistol drill motor are respectively and serially connected into an alternating current power supply loop of the pistol drill, an infrared distance measuring sensor is arranged on the case, meanwhile, a distance measuring control circuit is arranged in the case, the distance measuring control circuit comprises a singlechip microcomputer, a relay and an internal power supplying power supply, the singlechip microcomputer is connected with the infrared distance measuring sensor, the relay is connected with the singlechip microcomputer, and the internal power supplying power supply is used for providing electricity for the infrared distance measuring sensor, the singlechip microcomputer and the relay, a normally closed contact of the relay is also serially connected into the alternating current power supply loop of the pistol drill, and in addition, the alternating current power supply loop of the pistol drill can be switched off through receiving control signals corresponding to the preset distance measuring depth output by the singlechip microcomputer. The depth of drilling holes can be automatically calculated during the hole drilling, in addition, the hole drilling can be immediately stopped when the drilling holes reach the preset depth, the artificial intervention is not needed, the control precision on the depth of the drilling holes is high, the error is small, and the use is very convenient.

Description

technical field [0001] The invention belongs to the technical field of improving pistol drills, and in particular relates to a pistol drill with a distance measuring function. Background technique [0002] At present, the pistol drills on the market do not have the distance measuring function, and the depth of drilling basically needs to be controlled by the operator himself. For a type of drilling operation that requires high precision, if the operator is negligent or responds slowly, the drilling depth will often be exceeded, so there are disadvantages of delay and error, and it is difficult to achieve accuracy. [0003] Of course, there are a few brands of pistol drills with a mechanical rod-type device for limiting the drilling depth, but it is only a limitation, and it is impossible to accurately control the drilling depth, and there are still many inconveniences in actual use. Infrared ranging sensor is an existing ranging sensing device that has been maturely used in...

For a type of drilling operation that requires high precision, if the operator is negligent or responds slowly, the drilling depth is often exceeded, so there are disadvantages of delay and error, and it is difficult to achieve accuracy

[0003]Of course, there are a few brands of pistol drills with a mechanical rod-type device that limits the drilling depth, but it is only a limitation, and it cannot be accurate to the drilling depth Control, there are still many inconveniences in actual use

Infrared ranging sensor is an existing ranging sensing device that has been maturely used in many fields, but there is no report on its application in pistol drills
