Technical Field

[0001] The utility model relates to the field of metal product drilling, in particular to a drilling device used for metal product processing. Background Art

[0002] Metal products are extremely common in our daily lives. They are materials with metallic properties composed of metal elements or mainly composed of metal elements. Common metal products include stainless steel, aluminum alloy, copper alloy, etc.

[0003] In the process of processing metal product plates, in order to meet different designs and uses, drills are used to drill holes in metal product plates. In order to reduce the temperature of the drill, coolant is generally sprayed on it during the drilling process to cool it down. However, when facing deeper holes, the drill drills deeper, and the coolant cannot completely cool the position where the drill drills into the metal, causing the temperature of the drill to increase as it approaches the head surface, resulting in undesirable phenomena such as larger hole diameter, cracked hole wall, and sintered materials left at the bottom of the hole, affecting the accuracy and quality of drilling. Utility Model Content

[0004] The utility model aims to provide a drilling device for metal product processing, which effectively solves the problem that when the existing drill is drilling a deeper hole, the coolant cannot completely cool the drill bit's drilling position, causing the hole diameter to become larger, the hole wall to break, and sintered materials to remain at the bottom of the hole.

[0005] The technical solution of the utility model is as follows:

[0006] A drilling device for metal product processing, comprising a metal steel plate, a drill bit is arranged above the metal steel plate, a column hole is arranged inside the drill bit, a liquid infusion tube inserted into the column hole is arranged on the drill bit, a water pump box connected to an external power supply is arranged at the other end of the liquid infusion tube, the drill bit is divided into an upper drill body and a lower drill body, and the lower drill body is provided with liquid outlet holes of multiple heights;

[0009] Furthermore, an annular matching groove is provided inside the upper drill body, and an annular locking portion is provided on the top of the lower drill body. When the upper drill body and the lower drill body are locked, the annular locking portion is locked in the annular matching groove, and a rubber pad is provided on the top of the annular locking portion.

[0010] Furthermore, the number of layers of the liquid outlet holes is not less than two, and the liquid outlet holes in each layer are distributed in a circle around the outer wall of the drill bit.

[0011] Furthermore, penetrating positioning rods are provided on the four corners of the horizontal plate, and the positioning rods are movably arranged on the horizontal plate. A suction cup is provided at one end of the positioning rod close to the metal steel plate, and fixedly connected handrails are provided on both sides of the horizontal plate.

[0012] Furthermore, the placement component includes a frame plate and a positioning plate. The cross section of the frame plate is a hollow rectangle. The metal steel plate is placed on the top of the frame plate. The top of the frame plate is provided with slots around the edges.

[0013] Furthermore, the cross-section of the positioning plate is L-shaped, the positioning plate is movably arranged in the slot, the bottom of the frame plate is provided with a threaded part that passes through the frame plate and locks with the positioning plate, and when the metal steel plate is positioned, the vertical side wall of the positioning plate fits with the side wall of the positioning steel plate.

When the drill bit drills into a thicker metal steel plate, the coolant entering the metal steel plate during the drilling process can cool the drilled part, effectively avoiding the high surface temperature of the drill bit, resulting in the increase of the borehole diameter, the cracking of the hole wall, the retention of sintered materials at the bottom of the hole, and other undesirable phenomena, thereby improving the accuracy and quality of drilling holes in the metal steel plate.

[0016] 2. The utility model divides the drill bit into an upper drill body and a lower drill body, and the upper drill body and the lower drill body are locked by threads. After the drilling is completed, the upper drill body and the lower drill body can be separated, so that the metal chips inside the column hole can be cleaned out to prevent the liquid outlet from being blocked for a long time.

[0017] 3. The utility model provides a positioning rod on the horizontal plate, and a suction cup is provided at the bottom of the positioning rod. When drilling is required, the chassis is fixed on the metal steel plate. When drilling, the horizontal plate is lowered on the positioning rod, thereby realizing the drilling of the metal steel plate and improving the stability during drilling.

[0018] 4. The utility model sets a placement component, the metal steel plate is placed on the frame plate, the positioning plate is clamped in the slot, and the frame plate and the positioning plate are locked by screws, so as to fix the metal steel plate and ensure that the metal steel plate will not deviate when drilling.

The upper drill body 2-1 is provided with an annular matching groove 10, and the top of the lower drill body 2-2 is provided with an annular locking portion 11. When the upper drill body 2-1 and the lower drill body 2-2 are locked, the annular locking portion 11 is locked in the annular matching groove 10. The outer wall of the upper drill body 2-1 and the outer wall of the lower drill body 2-2 have the same diameter. Therefore, after the drilling is completed, the metal chips entering the column hole 3 can be cleaned out by separating the upper drill body 2-1 and the lower drill body 2-2. It is convenient and flexible to avoid the situation where the metal chips block the liquid outlet 6.

[0028] The lower drill body 2-2 is provided with multiple layers of liquid outlet holes 6, the number of layers of the liquid outlet holes 6 is not less than two layers, and the liquid outlet holes 6 of each layer are distributed in a circle around the outer wall of the drill bit 2. The provided liquid outlet holes 6 can be used to cool the drilled part when drilling a thicker metal steel plate 1, so as to avoid deformation of the hole caused by excessive temperature.

[0029] A transverse plate 7 is provided on the top of the drill bit 2, a motor 8 with an external power supply is provided on the top of the transverse plate 7, the output shaft of the motor 8 is connected to the drill bit 2, and a placement component is provided at the bottom of the metal steel plate 1, and the placement component fixes the metal steel plate 1 when drilling.

[0030] A vertical mounting plate 9 is provided on one side of the top of the infusion tube 4 close to the column hole 3 and on one side of the transverse plate 7 close to the water pump box 5. The water pump box 5 is fixedly connected to the mounting plate 9, and the coolant is automatically pumped through the water pump box 5.

[0031] A rubber pad 12 is provided on the top of the annular locking portion 11. The rubber pad 12 can increase the sealing performance of the internal connection between the upper drill body 2-1 and the lower drill body 2-2 to prevent the coolant from leaking out.

[0032] The four corners of the horizontal plate 7 are provided with penetrating positioning rods 13, which are movably arranged on the horizontal plate 7 so that the horizontal plate 7 can be vertically lifted and lowered on the positioning rods 13, so that the drill bit 2 can be perpendicular to the metal steel plate 1 to ensure the verticality of the hole.

[0033] A suction cup 14 is provided at one end of the positioning rod 13 close to the metal steel plate 1, so that the positioning rod 13 can be completely adsorbed on the metal steel plate 1, and fixed handrails 15 are provided on both sides of the cross plate 7 to better facilitate the drilling of the workers.

[0034] The placement component includes a frame plate 16 and a positioning plate 17. The cross-section of the frame plate 16 is a hollow rectangle.

[0038] The annular locking portion 11 on the lower drill body 2-2 is aligned with the annular matching groove 10 in the upper drill body 2-1, so that the annular locking portion 11 is locked into the annular matching groove 10 to realize the assembly of the drill bit 2. After the drill bit 2 is moved to a suitable position, the positioning rod 13 is placed vertically, and the suction cup 14 is adsorbed on the surface of the metal steel plate 1. The motor 8 is started to rotate the drill bit 2, and the cross plate 7 is lowered on the positioning rod 13 through the handrail 15.
