Hole drilling device having depth adjusting function

Abstract

The invention relates to the field of hole drilling devices and discloses a hole drilling device having the depth adjusting function. The hole drilling device having the depth adjusting function comprises a base. A supporting rod is fixedly installed on one side of the top of the base. A first bearing is fixedly arranged in the middle of the supporting rod in a sleeved manner. The front face, theback face and the side face of the first bearing are all fixedly connected with tow bars. The top of the supporting rod is movably connected with a rotating plate in a sleeved manner. One side of thetop of the rotating plate is fixedly provided with a first drive motor. The bottom end of an output shaft of the first drive motor is fixedly connected with a lead screw. According to the hole drilling device having the depth adjusting function, through downward movement of a following block, a following shaft is driven to move downwards, the following shaft is made to be located at the needed drilling depth according to scales on a fixing pipe, and through rotation of a nut, the following shaft is fixed by means of cooperation of a locating sleeve; during drilling, when a mark post makes contact with the following shaft, the hole drilling device reaches the needed drilling depth, and therefore the drilling depth is accurately controlled; and in this way, the quality of a machined device is improved, and the phenomenon that the hole drilling depth of the machined device do not meet a demand, so that waste is caused is avoided.

Description

technical field [0001] The invention relates to the field of drilling equipment, in particular to a drilling device with adjustable depth. Background technique [0002] Drilling device refers to the general term for equipment used to process holes on solid materials. Common drilling devices include electric drills, drilling machines, and drilling devices are widely used. In the construction industry, they are suitable for building beams, plates, columns, Wall reinforcement, decoration, wall installation, installation of brackets, railings, billboards, outdoor units of air conditioners, guide rails, satellite receiver elevators, steel structure workshops, etc. [0003] However, when the common drilling device drills the processing device, the drilling depth cannot be accurately controlled, so that the quality of the device is not high, and the common drilling device is difficult to take out the drill bit after the drilling is completed, so that the drilling The drilling effi...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a depth-adjustable drilling device, which has the advantages of being convenient to precisely control the drilling depth, facilitating the removal of the drill bit and preventing the splashing of iron filings, etc. When drilling, the drilling depth cannot be accurately controlled, so that the quality of the device is not high, and the common drilling device is difficult to remove the drill bit after the drilling is completed, so that the drilling efficiency of the drilling device is reduced, and the common When the advanced drilling device is drilling metal parts, because there are no protective measures, the iron filings generated during drilling often splash around, which not only affects the environmental sanitation, but also easily causes the operator to and product scratches
