Description

Technical Field

[0001] The utility model relates to the technical field related to numerical control drilling machines, and in particular to a numerical control drilling machine with a protective function. Background Art

[0002] CNC drilling machines are mainly used for drilling, reaming, boring, tapping and other processing. They are digitally controlled hole processing machines mainly for drilling. CNC drilling machines can be divided into CNC vertical drilling machines, drilling centers, printed circuit board CNC drilling machines, CNC deep hole drilling machines and other large CNC drilling machines according to their layout type and functional characteristics. When working, the operator transmits the written drilling program to the control system of the CNC drilling machine, and the control system of the CNC drilling machine will drill the parts according to the program. Traditional CNC drilling machines lack detection components. When foreign objects appear in the construction area, it is easy to collide with the machine. During the operation of the CNC drilling machine, there is manual operation of the workpiece. CNC machine tools without detection components have hidden dangers in personnel construction safety. Therefore, when performing CNC drilling, in order to ensure the safety of construction personnel and prevent equipment damage, a CNC drilling machine with protective function is particularly needed.

[0003] Because most of the existing safety protection devices usually simply protect the drill bit from damage when protecting the machine tool. Although this method can play a certain protective role, there are still some problems and shortcomings in actual use. For example, when the machine tool presses the workpiece when the working state is lowered, the construction worker is still in the working area. At this time, the protective drill bit alone cannot completely solve the safety hazard problem of the construction worker at work. Utility Model Content

When in use, when the machine is started, first place the workpiece to be processed in the processing area and then connect the power of the electric box 211. At this time, the infrared sensor 207 will continue to focus the infrared light and convert it into an electrical signal. When the drilling machine device 1 starts to move downward, the pressing plate 206 moves to the surface of the workpiece and squeezes it. The spring 203 fixedly connected to the surface of one side of the pressing plate 206 shrinks and deforms, and the telescopic structure composed of the second connecting rod 205 and the first connecting rod 204 is at The drilling machine device 1 is in a retracted state until the drill bit can process the surface of the workpiece. The drilling machine device 1 stops moving downward and starts processing. When the infrared sensor 207 detects foreign matter during the downward movement of the drilling machine device 1, it will send a corresponding electrical signal to the controller 208. At this time, the electrical signal will be received by the sensor 209, and then the sensor 209 will convert the electrical signal into a processable digital signal, and then transmit it to the controller 208. Finally, the controller 208 controls the motor to stop urgently through the mainboard 210, immediately cuts off the power supply of the electrical box 211, and stops the operation of the equipment, thereby avoiding equipment damage and personal injury.

[0023] Furthermore, the dust removal mechanism 3 includes a fixed block 301, a dust suction pipe 302, a dust removal box 303, a groove 304, a dust removal plate 305 and a fan 306. The fixed block 301 is fixedly connected to one side surface of the drilling machine device 1, the dust suction pipe 302 is fixedly connected to one side surface of the fixed block 301, the dust removal box 303 is fixedly connected to one end surface of the dust suction pipe 302, the fan 306 is connected to the outer wall of the dust removal box 303, the inner wall of the dust removal box 303 is provided with a groove 304, and the dust removal plate 305 is tightly fitted to one side surface of the groove 304.

When the drilling machine device 1 starts working, the fan 306 is powered on and is in working state. Under the rotation of the fan 306, the gas in the dust removal box 303 and the dust collection tube 302 forms an airflow and moves toward the exhaust holes opened on the surface of the dust removal box 303. The dust collection tube 302 drives the metal dust generated during the surface processing of the workpiece to move into the dust collection box 303.

[0024] Furthermore, the inner wall size of the first connecting rod 204 matches the outer wall size of the second connecting rod 205, and the first connecting rod 204 and the second connecting rod 205 form a telescopic structure. Through the setting of the first connecting rod 204, it can be used in conjunction with the second connecting rod 205 to make the pressing plate 206 telescopic.

[0025] Furthermore, the inner wall size of the spring 203 matches the outer wall size of the first connecting rod 204. The spring 203 is provided in six groups. Through the setting of the first connecting rod 204, the spring 203 will only deform in the up and down directions when subjected to force, thereby avoiding excessive deformation of the spring 203.

Through the arrangement of the second connecting rod 205, it is used in conjunction with the first connecting rod 204, and the second connecting rod 205 is retracted to the inside of the first connecting rod 204 to realize the extension and retraction of the pressing plate 206.

[0028] Furthermore, the dust suction tube 302 is made of a rubber hose with good elasticity. The outer wall size of the dust suction tube 302 matches the surface size of one side of the fixed block 301. Through the setting of the dust suction tube 302, when the drilling machine device 1 is displaced, the dust suction tube 302 can still clean metal dust due to its good elasticity, ensuring stable dust removal.

[0030] Working principle: During use, when the machine is started, first place the workpiece to be processed in the processing area and then connect the power supply of the electrical box 211. At this time, the infrared sensor 207 will continue to focus the infrared light and convert it into an electrical signal. When the drilling machine device 1 starts to move downward, the pressing plate 206 moves to the surface of the workpiece and squeezes it. The spring 203 fixedly connected to the surface of the pressing plate 206 shrinks and deforms. The telescopic structure composed of the second connecting rod 205 and the first connecting rod 204 is in a contracted state until the drill bit can process the surface of the workpiece. The drilling machine device 1 stops moving downward and starts processing. When the infrared sensor 207 detects foreign matter during the downward movement of the drilling machine device 1, it will send a corresponding electrical signal to the controller 208. At this time, the electrical signal will be detected by the sensor 209 receives it, and then the sensor 209 converts the electrical signal into a processable digital signal, and then transmits it to the controller 208. Finally, the controller 208 controls the motor to stop urgently through the mainboard 210, immediately cuts off the power supply of the electric box 211, and stops the operation of the equipment, thereby avoiding equipment damage and personal injury. When the drilling machine device 1 starts to work, the fan 306 is powered on and is in working state. Under the rotation of the fan 306, the gas in the dust removal box 303 and the dust suction pipe 302 forms an airflow and moves toward the exhaust hole opened on the surface of the dust removal box 303. The dust suction pipe 302 drives the metal dust generated during the surface processing of the workpiece to move into the dust suction box 303. The metal dust is blocked on the surface of the dust removal plate 305 when passing through it, thereby achieving the dust removal effect of the workpiece during the processing.
