Description

Technical Field

[0001] The invention belongs to the technical field of drilling machines, and in particular relates to drilling equipment for building materials. Background Art

[0002] Building materials include plates, which are usually made into flat rectangular building material plates of standard size. They are used as components of walls, ceilings or floors. They also refer to metal plates that are forged, rolled or cast. Building plates are divided into thin plates, medium plates, thick plates and extra-thick plates. A drilling machine is required for drilling holes during the production process to facilitate installation.

[0003] In a Chinese patent with publication number CN117001398A, a new type of drilling equipment for building materials is mentioned, which relates to the field of building material processing technology, including a processing table, wherein a processing groove is provided at the center axis of the top outer wall of the processing table. When it is necessary to drill holes in building boards, the staff can place the building boards inside the processing groove and push the building boards to move. When the building boards are moved to a suitable position, the electric telescopic rod can be started to drive the moving plate to move, and at the same time, the pressing vertical plate and the pressing deformation capsule can be driven to move. Under the effect of the movement, the pressing deformation capsule can press the building boards, thereby preventing the building boards from shifting during the drilling process, thereby affecting the processing effect of the building boards. When it is necessary to drill holes in building boards, the adjusting cylinder can be started to drive the adjusting block and the fixed block to move, and at the same time, the motor can be started to drive the rotating shaft to move. Under the effect of the rotating shaft rotation, the purpose of drilling holes in the building boards can be achieved.

[0004] When the above-mentioned equipment is in use, although it can drive the extrusion tube to rotate through the motor that originally drives the rotary head, thereby causing the drill bit to vibrate up and down to improve the drilling efficiency, and perform gas blowing to clean the waste chips stuck on the drill, this also causes the drill bit to be unstable when rotating. When faced with fine drilling depth, the vibration cannot be eliminated, and thus the processing accuracy will be limited. Summary of the invention

[0051] In this embodiment, the wind guide plate 45 is tilted downward by thirty degrees to guide the wind; the fan 49 is connected to one side of the bracket 44 through an axial rotation, and a pulley is also provided at the axis, so that the connecting belt 491 connects the two fans 49. In addition, the axis of one of the fans 49 has two pulleys, so that it can be connected to the connecting shaft 48 through the connecting belt 491.

[0052] In a further embodiment, the bottom end of the driving shaft 191 is fixedly connected to a drill bit 15, and the drill bit 15 is used for drilling holes.

[0053] In this embodiment, a controller is provided on one side of the drilling platform 1. The drilling platform 1, the gantry slide 11, the X-axis slide 12, the driving cylinder 14, the stepper motor 19 and the drill bit 15 are all drilling machines in the prior art. In addition, the stepper motor 19 can be rotated through programming so that when it rotates, the cylinder linkage gear 192 can engage with the transmission gear 1 36 and the transmission gear 2 46.

[0054] The working principle of the present invention is as follows:

[0055] When the control device outside the drilling platform 1 operates the driving cylinder 14, the Y-axis slider 13 is driven to move downward as a whole. At this time, the driving stepper motor 19 can drive the drill bit 15 to rotate through the driving shaft 191 to drill holes in the building board;

[0056] When the transmission slot 16 on one side of the Y-axis slider 13 moves to be level with the transmission gear 1 36, the transmission gear 1 36 will mesh with the linkage gear 192 inside the transmission slot 16. At this time, the stepper motor 19 operates again to rotate the linkage gear 192 through the drive shaft 191, thereby driving the transmission gear 1 36 and the transmission shaft 35 to rotate, and after being driven by the transmission belt 34, the connecting gear 33 in the docking slot 32 will rotate. Since the transmission slot 16 is level with the transmission gear 1 36, the Y-axis slider 13 is in the At the high position where the X-axis slider 12 can slide, and because the linkage cam 18 is located inside the special-shaped guide rail 22 and slides, and at this time the linkage cam 18 is located at the high position of the special-shaped guide rail 22, the I-shaped plate 21 is pulled close to the support frame 31 by the tension spring 28, and the docking gear 26 is meshed with the connecting gear 33, thereby rotating the reciprocating screw rod 23, so that the half frame block 24 moves up and down, and the cleaning brush 25 can clean the periphery of the drill bit 15 to remove the debris remaining on the surface of the drill bit 15;

[0057] When the Y-axis slider 13 moves downward to punch holes in the building board, the linkage convex shaft 18 also moves downward, so that the special-shaped guide rail 22 takes the I-shaped board 21 away from the support frame 31, and then the half frame block 24 moves away from both sides of the drill bit 15, so as not to affect the drilling process of the building board by the drill bit 15;

[0058] When the drill bit 15 drills through the board, the linkage gear 192 will mesh with the transmission gear 2 46, thereby causing the two fans 49 located on the inner side of the air guide box 41 to rotate through the transmission of the linkage shaft 47, the connecting shaft 48 and the connecting belt 491, thereby generating wind force, and the generated wind force will be guided by the wind guide plate 45 and blow obliquely toward the punched building board, so that not only the waste generated during the punching can be cleaned up, but also the position of the punching can be cleaned up.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
