DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0031] Combination Figure 1-Figure 7 The present invention discloses an automated gantry deep hole processing machine tool for hardware production, comprising a base 11, a support column 12 is vertically connected to the top surface of the base 11, a positioning member 13 is connected to the top of the support column 12, a drilling work platform 14 is connected to the front surface of the support column 12, and a clamping member 15 is installed on one side surface of the drilling work platform 14, and the clamping member 15 is used to fix the workpiece;

[0032] In the deep hole processing of hardware, one-way drilling requires a longer drill bit, which makes it difficult to control the force of the drill bit and difficult to remove chips in deep hole processing, which is not conducive to the formation of holes. In order to solve this problem, the workpiece is first clamped and fixed by the clamping member 15. After clamping and fixing, the stability is more excellent. In order to solve the difficulty of deep hole drilling, the chip removal unit 2, the drilling unit 3 and the adaptive unit 4 are provided to solve this problem. The specific operation is as follows:

[0033] A chip removal unit 2 is provided at the center of the drilling work platform 14. The chip removal unit 2 includes a chip removal port 21. The chip removal port 21 is provided at the center of the drilling work platform 14. The interior of the drilling work platform 14 is configured to be hollow. A ventilation duct 22 is embedded in the front of the drilling work platform 14. The bottom end of the ventilation duct 22 is connected to a suction fan. The suction fan and the ventilation duct 22 are used to extract air into the interior of the drilling work platform 14.

[0034] During drilling, the debris is collected through the chip discharge port 21, wherein the suction force generated by the suction fan is transmitted to the drilling work platform 14 through the ventilation duct 22, thereby the internal stroke of the drilling work platform 14 is in a state of negative pressure, and the debris generated at this time will fall through the chip discharge port 21 to the inside of the drilling work platform 14 for storage, so that the debris has a storage space and the debris can be collected. The timely collection of debris can effectively avoid its accumulation in the processing area, prevent the debris from interfering with the drilling operation, and ensure the smoothness of the processing process. Moreover, the drilling work platform 14 is specially provided for the debris. This storage space gives the debris a clear place to go and no longer scatters randomly. This not only keeps the working environment clean and tidy, reduces the safety hazards caused by the scattering of debris, but also facilitates the subsequent centralized processing of the debris, greatly improving the cleanliness, safety and work efficiency of the entire drilling process.

[0035] The support column 12 is also connected to a spindle motor 16, and a drilling unit 3 is provided at the output end of the spindle motor 16. The drilling unit 3 includes a main drill bit 31. The output end of the drilling work platform 14 is provided with a main drill bit 31, and the main drill bit 31 is arranged at the upper end of the drilling work platform 14 perpendicular to the drilling work platform 14. A track frame 33 is fixedly connected to the support column 12, and a movable frame 32 is embedded in the track frame 33. A transmission gear 34 is meshed on one side of the movable frame 32, and the transmission gear 34 is connected to the track frame 33. The movable frame 32 is provided with two groups, and the movable frames 32 are both connected with a collar member 36, one of which is sleeved on the auxiliary drill bit 35. The auxiliary drill bit 35 is provided with a collar member 36. 5 and the outer surface of the main drill bit 31 are sleeved with a collar member 36, the collar member 36 and the auxiliary drill bit 35 are rotatably connected, another group of collar members 36 are sleeved on the main drill bit 31, the main drill bit 31 and the collar member 36 correspond to each other, the main drill bit 31 is driven by the spindle motor 16, the spindle motor 16 drives the adaptive unit 4 to drive the auxiliary drill bit 35 to rotate, the main drill bit 31 and the auxiliary drill bit 35 are embedded with extension rods 38, the extension rods 38 are provided with two groups, the first group is connected to the main drill bit 31, and the top of the extension rods 38 is provided with a rotating sleeve 37, the second group is connected to the auxiliary drill bit 35, and the bottom end of the extension rod 38 embedded in the auxiliary drill bit 35 is connected with the rotating sleeve 37;

[0036] The output end of the spindle motor 16 is connected to the first group of rotating sleeves 37, and the spindle motor 16 drives the rotating sleeve 37 to rotate. The outer surface of the rotating sleeve 37 is connected to a first transmission belt 44, and the other end of the first transmission belt 44 is connected to an upper roller 42. The top of the base 11 is connected to an adaptive unit 4, and the adaptive unit 4 includes a transmission rod 41. The outer surface of the transmission rod 41 is connected to an upper roller 42. The upper roller 42 and the first group of rotating sleeves 37 are connected through the first transmission belt 44. The outer surface of the transmission rod 41 is also connected to The lower roller 43 has a second transmission belt 45 sleeved on its outer surface. The second transmission belt 45 is sleeved on the second set of rotating sleeves 37 at a side away from the lower roller 43. The spindle motor 16 drives the first set of rotating sleeves 37 to rotate and drive the first transmission belt 44, thereby driving the upper roller 42, the transmission rod 41 and the lower roller 43 to rotate. The lower roller 43 rotates and drives the second transmission belt 45 to drive the second set of rotating sleeves 37 to rotate. The first set of rotating sleeves 37 rotates and drives the main drill bit 31 to rotate. The second set of rotating sleeves 37 rotates and drives the auxiliary drill bit 35 to rotate.

[0037] The spindle motor 16 serves as a power source, and transmits power to the main drill bit 31 and the auxiliary drill bit 35 by rotating the sleeve 37, the collar member 36, the transmission belt and other components. This multi-stage transmission design ensures the stability and reliability of power transmission, so that the drill bit can maintain a stable working state during high-speed rotation and feeding, reducing processing errors caused by unstable power. In addition, stable power transmission helps to reduce the vibration and impact of the tool during operation, reduce tool wear, and extend the service life of the tool, thereby reducing processing costs.

[0038] A rack is provided on one side where the movable frame 32 and the transmission gear 34 mesh. Two groups of transmission gears 34 are provided. The two groups of transmission gears 34 mesh with each other. Each group of transmission gears 34 meshes with one group of movable frames 32. A power source for rotating the transmission gear 34 is installed on the track frame 33. The output end of the power source for rotating the transmission gear 34 is connected to the transmission gear 34. The power source for rotating the transmission gear 34 drives the transmission gear 34 to rotate.

[0039] The main drill bit 31 and the auxiliary drill bit 35 correspond to the center position of the chip removal opening 21 , and the top surface and the bottom surface of the workpiece are drilled by the main drill bit 31 and the auxiliary drill bit 35 respectively.

[0040] The transmission rod 41, the upper roller 42, the lower roller 43, the first transmission belt 44, the second transmission belt 45 and other components in the adaptive unit 4 cooperate with the main drill bit 31 and the auxiliary drill bit 35. During the drilling process, the position and working state of the drill bit can be automatically adjusted according to the different thicknesses and processing requirements of the workpiece. For example, when the thickness of the workpiece changes, the main drill bit 31 and the auxiliary drill bit 35 can be flexibly moved closer or farther from each other through the coordinated action of the transmission components to ensure the quality and efficiency of drilling.

[0041] This adaptive adjustment capability enables the machine tool to adapt to the processing needs of different types of hardware. Whether it is long-axis hardware or special connectors, the machine tool can guarantee processing accuracy and efficiency, thereby improving the versatility and adaptability of the machine tool.

[0042] When drilling, when the spindle motor 16 starts to rotate, the main drill bit 31 is driven to rotate, and the auxiliary drill bit 35 is also driven to rotate, and the workpiece is drilled by the rotation of the main drill bit 31 and the rotation of the auxiliary drill bit 35;

[0043] When the spindle motor 16 drives the first set of rotating sleeves 37 to rotate, the main drill bit 31 is driven to rotate. The rotation of the first set of rotating sleeves 37 drives the rotation of the first transmission belt 44. The rotation of the first transmission belt 44 drives the upper roller 42, the lower roller 43 and the transmission rod 41 to rotate synchronously. After the lower roller 43 rotates, it drives the second transmission belt 45 to rotate. At this time, it drives the second set of rotating sleeves 37 to rotate. Through the rotation of the main drill bit 31 and the rotation of the collar member 36, the workpiece is drilled. When advancing, the rotation of the motor first drives the transmission The movable gear 34 rotates. When the transmission gear 34 rotates, the movable frame 32 slides inside the track frame 33. The movable frame 32 moves to drive the collar member 36 and thus drives the main drill bit 31 and the auxiliary drill bit 35. When the main drill bit 31 and the auxiliary drill bit 35 are getting closer, the top surface and the bottom surface of the workpiece are drilled respectively. The main drill bit 31 and the auxiliary drill bit 35 are pushed forward by controlling the rotation speed of the transmission gear 34. In order to adapt to the push of the main drill bit 31 and the auxiliary drill bit 35, a rotating sleeve 37 and an extension rod 38 are provided to adapt to this movement.

[0044] When the auxiliary drill bit 35 and the main drill bit 31 are close to each other, the extension rod 38 will be drawn out from the inside of the auxiliary drill bit 35 and the main drill bit 31, so that the auxiliary drill bit 35 and the main drill bit 31 can be driven to rotate by rotating the sleeve 37 and the main drill bit 31 and the auxiliary drill bit 35 can be brought close to each other.

[0045] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0046] 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 the scope of the present invention is defined by the appended claims and their equivalents.
