Abstract

The invention discloses drilling equipment for machining a building metal pipe fitting, relates to the technical field of drilling, and aims to solve the problems that a worker can only control the drilling forward speed and cannot accurately control the drilling pressure of a drill bit on the pipe fitting when drilling the pipe fitting by using the drilling equipment due to the fact that the material of the building metal pipe fitting is different from the thickness of the pipe wall. Through sliding connection of a groove ring of a groove disc and a sliding disc, the sliding disc slides in an adjusting groove of a threaded cylinder in the process of rotating and adjusting the position, the compression degree of a spring is changed, different pressures are provided for the surface of the pipe in the drilling process, and in the process that workers drill the building pipe, the pipe is not prone to deformation in the drilling process. The drilling pressure adjustment can be performed according to the difference between the pipe fitting material and the pipe wall thickness, so that the pipe fitting can be drilled within a proper pressure range during drilling, and the pipe fitting deformation caused by overlarge drilling pressure force is avoided.

[0002] At present, there are various metal pipes in the construction field. In the field of metal pipe processing technology, drilling is a common processing method. A drilling machine refers to a mechanical device mainly used to process holes in solid materials. It can drill holes in various materials such as metal, wood, and plastic through rotating tools or drill bits. There are various types of drilling machines, including desktop drilling machines, vertical drilling machines, and radial drilling machines to meet different processing needs and scenarios. Desktop drilling machines are widely used in metal pipe drilling due to their flexibility, ease of use, and high production efficiency. Due to the different materials and wall thicknesses of building metal pipes, workers can only control the drilling speed when using drilling equipment to drill holes in the pipes, but cannot accurately control the drilling pressure of the drill bit on the pipes, causing the pipes to deform during the drilling process.

When encountering an excessively high drilling speed, the spring is compressed by pressure, so that the chuck and the drill bit move up and enter the inside of the chuck. When sliding to a certain extent, they are disengaged from the clamping strip and stop rotating to avoid damage to the pipe fittings.

[0005] Preferably, the fixing mechanism comprises a support plate, a perforated plate is installed on the outer side of the support plate, the opening of the perforated plate is slidably adapted to the outer side of the guide rod, a slide slot plate is fixedly installed on the top of the support plate, the number of the slide slot plates is two, and the slide slot plates are symmetrically installed along the center position of the axis of the support plate, the opposite surfaces of the slide slot plates are provided with slide slots, and a clamping mechanism is slidably installed at the slide slot of the slide slot plate, and the clamping mechanism comprises a support frame, a rod hole is opened on the top of the outer side of the support frame, a screw rod is rotatably installed at the rod hole of the support frame, a turntable is installed at one end of the screw rod, and a slide rack is threadedly connected to the outer side of the screw rod.

During the drilling process of the construction pipe fittings, the workers can adjust the drilling pressure according to the difference between the pipe fitting material and the pipe wall thickness, so that the pipe fittings can be drilled within a suitable pressure range during drilling, avoiding excessive drilling pressure and causing deformation of the pipe fittings.

[0008] Second, the cartridge is connected with the chuck through the clamping strip of the cartridge to transmit the rotational force during drilling. When encountering an excessively high drilling speed, the spring is compressed under pressure to move the chuck and the drill bit up and into the cartridge.

[0009] 3. The heat dissipation tube conducts the heat inside the drilling mechanism to the outside through the heat dissipation holes of the heat dissipation tube and the empty slots of the fixed frame, so as to avoid the temperature rise of the internal structure due to the friction of rotation and sliding, and the heat cannot be discharged, resulting in long-term operation of parts and damage, thereby improving the service life of the equipment.

[0010] Fourth, the rotating block can make the inner clamping plate fit and clamp the positions of the pipe fittings with different outer diameters by rotating the rotating block, so as to avoid the clamping claws being unable to clamp the special pipe fittings completely, thereby improving the clamping and fixing effect of the pipe fittings.

[0011] 5. The rubber plate is connected to the turnbuckle so that when the clamping claw clamps the pipe fitting, the rubber plate fits the surfaces of both sides of the pipe fitting, increasing the contact area with the surface of the pipe fitting, increasing the friction force, and avoiding the rotation of the pipe fitting during the drilling process, which causes the deviation of the drilling position.

[0019] When in use, the construction pipe fittings are manually placed into the drilling equipment, and the pipe fittings are clamped and fixed by the fixing mechanism 3. After the pipe fittings are fixed, the position of the pipe fittings is adjusted so that the drilling position is directly below the drilling mechanism 2. The electric control box 4 is manually operated and relevant parameters are input into the electric control box 4, so that the motor 6 drives the drilling mechanism 2 to rotate, and at the same time, the cylinder 7 pushes the fixing mechanism 3 upward, and under the restriction of the guide rod 5, it approaches the drilling mechanism 2, and the drilling position of the pipe fitting is drilled through the drilling mechanism 2.

When the outer diameter of the pipe fitting is large, the rubber pad 3263 contacts the surface of the pipe fitting. When the outer diameter of the pipe fitting is small, the anti-skid pad 3264 contacts the surface of the pipe fitting. The pipe fitting is fixed by applying pressure on both sides at the same time. During the fixing and clamping process, the rubber pad 3263 contacts the surface of the pipe fitting and fits better with the surface of the pipe fitting through the deformation characteristics of the rubber.

[0023] During the drilling process, the motor 6 drives the rotating shaft 201 to rotate, so that the rotating shaft 201 drives the heat dissipation tube 211 through the connecting plate 204, and the rotation of the heat dissipation tube 211 drives the threaded tube 208 and the chuck 209 to rotate.

[0024] Before drilling, the grooved plate 206 is rotated to drive the threaded ring 207 to rotate, and the position is changed on the outer surface of the threaded tube 208.
