Description
Technical Field
[0001] The utility model relates to the field of hardware processing, in particular to a drilling and tapping machine for hardware processing. Background Technique
[0002] Hardware parts often need drilling or tapping processing. When hardware workpieces are processed and produced, through holes are generally reserved to facilitate the fixed installation of hardware workpieces and other products through nuts and bolts. However, sometimes there are problems that it is inconvenient to install nuts and bolts during the installation of hardware parts. Therefore, sometimes it is necessary to perform drilling and tapping on the hardware parts, drill matching holes and grooves at the corresponding positions of the products, and complete the fixed installation of the hardware parts and the products through the screw self-locking of the bolts. When the existing drilling and tapping machine for hardware processing processes hardware parts, different fixtures need to be replaced to fix hardware parts with different shapes, which is not only troublesome but also has low work efficiency. Moreover, when drilling and tapping hardware parts, the drill bit is prone to overheating, affecting the drilling and tapping efficiency. At the same time, metal chips, cuttings and other particles will be generated during drilling and tapping. These particles splash everywhere and are easy to fall on the staff or even into the eyes, causing harm to the personnel.
[0003] Therefore, it is necessary to provide a new drilling and tapping machine for hardware processing to solve the above technical problems. Content of the Utility Model

The lower left side of the support rod is rotatably connected with a rotating column. At the lower part inside the rotating column, a tapping drill bit is fixedly connected. Several cooling holes are arranged in the middle of the rotating column, and the other ends of the cooling holes are arranged above the tapping drill bit. At the left side of the top of the support rod, a water storage box is fixedly connected. In the middle of the bottom of the water storage box, a main spray head water pipe is fixedly connected.

The coolant inside the water storage box flows into the main spray head water pipe and is sprayed out to cool the processing surface of the tapping drill bit. On the left side of the top of the base, baffles are connected through torsion springs on three sides. Under the action of the torsion springs, the baffles can block metal chips, cuttings and other particles generated during drilling and tapping, preventing these particles from splashing everywhere and falling on the staff or even into the eyes, causing harm to the personnel. On both sides of the left side of the base, chutes are arranged. Inside the chutes, second cylinders are slidably connected. At the top of the second cylinders, clamping plates are fixedly connected.

The main pulley is connected to a secondary pulley through a transmission belt. A rotating column is fixedly connected to the middle below the secondary pulley. Starting the first motor drives the main pulley to rotate, driving the secondary pulley to rotate, facilitating the rotation of the rotating column.
[0009] Preferably, a second motor is fixedly connected to the middle of the left side inside the base. A rotating shaft is fixedly connected to the driving part of the second motor. A support plate is fixedly connected to the top of the rotating shaft. First cylinders are fixedly connected to both sides of the top of the support plate. The first cylinders are rotatably connected to a fixing plate. The other end of the fixing plate is rotatably connected to a second cylinder. Starting the second motor drives the rotating shaft to rotate counterclockwise, driving the support plate to rotate counterclockwise, causing the fixing plate to drive the second cylinders to approach each other, facilitating the contact between the movable column and the hardware.
[0010] Preferably, an operation panel is fixedly connected to the left side in front of the base, facilitating the opening and closing of the internal driving device.

[0027] In an embodiment of the present utility model, please refer to Figure 1 and Figure 3 , a secondary spray head water pipe 7 is arranged on the left side of the middle of the main spray head water pipe 6. The spray head of the secondary spray head water pipe 7 is flush with the cooling hole 10.
