Lock hole drilling machine for indoor waterproof strengthened mould-pressed wooden door

Abstract

The invention relates to the technical field of door plate machining equipment, and discloses a lock hole drilling machine for an indoor waterproof strengthened mould-pressed wooden door. The lock hole drilling machine comprises a fixed frame, a drill floor pressing plate is arranged at the top of the outer surface of the fixed frame, supporting legs are arranged on the left side of the fixed frame, pressure springs are arranged at the tops of the outer surfaces of the supporting legs, the pressure springs are movably mounted at the positions, on the lower parts of the supporting legs, of theouter surfaces of the supporting legs in a sleeving mode, and vertical hole drill floors are fixedly mounted on the two sides outside the supporting legs correspondingly. According to the lock hole drilling machine for the indoor waterproof strengthened mould-pressed wooden door, through arrangement of a pre-hole drilling tool and internal structures thereof, a pre-hole drilling rod can be completely retracted into a reaming drilling tool under the blocking effect of a limiting clamping plate while rotating with the reaming drilling tool, the depth of a pre-hole can be effectively controlled when a lock cylinder hole is machined by a lock hole drilling tool, and thus the lock hole drilling tool can not only machine the lock cylinder hole but also machine a mounting hole of a lock.

Description

technical field [0001] The invention relates to the technical field of door panel processing equipment, in particular to a keyhole drilling machine for indoor waterproof reinforced molded wooden doors. Background technique [0002] Reinforced molded wooden door is a new type of low-carbon, environmentally friendly, beautiful and practical door panel with high quality and not easy to deform. It is mainly coated with adhesive between particleboard, moisture-proof board, medium fiberboard or hard fiberboard, etc. The door panel structure is produced by a high-tonnage molding press under high pressure conditions through one-time molding or two-time molding technology. [0003] As a safety mechanism installed at the entrance and exit of a building, the door panel is not just a simple plate-shaped structure, but a lock hole needs to be opened in the interior of one side to facilitate the subsequent installation of the door lock, but as a one-piece molded The reinforced wooden doo...

Problems solved by technology

[0006] The invention provides a keyhole drilling machine for indoor waterproof reinforced molded wooden doors, which can automatically adjust the position and height of the side milling cutter according to the thickness of the door panel, and can simultaneously complete the pre-hole and reaming of the lock core hole, reducing The configuration of the driving device and the advantages of low operation difficulty solve the problem that the existing keyhole drilling machine needs to constantly adjust the position and height of the side milling cutter according to the thickness of the door panel when facing different types of door panels, so that it will be replaced every time. For one type of door panel, it is necessary to adjust the position of the side milling cutter once, which leads to the low working efficiency of the keyhole drilling machine, and the increase of the cumulative error after multiple adjustments, resulting in the stability of the accuracy of the keyhole on the door panel The performance is poor, and because of the different functions of the lockhole, the required hole diameters are also different, and the existing lockhole drilling machine uses two sets of driving devices to drive different caliber drill bit, first pre-drill a small hole, and then use a larger drill bit for reaming to realize the processing of the lock cylinder hole with a larger inner diameter, but this processing method only needs to be used in the processing of the lock cylinder hole. Configure at least two sets of driving devices, thereby virtually increasing the preparation cost of the keyhole drilling machine and increasing the difficulty of operation of the keyhole drilling machine
