It can be understood that the specific embodiments described herein are only used to explain the related utility model, and not to limit the utility model. In addition, it should be noted that only parts related to the utility model are shown in the drawings for ease of description.

[0042] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and embodiments.

[0043] As Figures 1-3 shown, the utility model provides an electrical device for metal drilling, comprising:

[0044] The bottom plate 1 is used for mounting various components and providing support;

[0045] The conveying device is installed at one end of the bottom plate 1 and is used for conveying the metal to the drilling position;

[0046] The limiting plate 3 is fixedly installed on the bottom plate 1;

[0047] The clamping and pushing mechanism is installed on the bottom plate 1, and the clamping and pushing mechanism is used for moving towards or away from the limiting plate 3 to clamp or release the metal in cooperation with the limiting plate 3;

[0048] The proximity sensor is installed above the bottom plate 1 and can detect the position of the metal, and is used for sensing that the metal reaches the drilling position;

[0049] The drilling structure is installed on the bottom plate 1 and is used for drilling the clamped metal;

[0050] The infrared sensor is installed on the bottom plate 1 and is used for sensing the existence of the metal after the drilling is completed;

[0051] The releasing device is installed on the bottom plate 1 and is used for pushing the metal after the drilling is completed according to the sensing signal of the infrared sensor, and releasing the metal after the drilling is completed.

[0052] The core basis of the device is the bottom plate 1, which is processed by a solid metal material, and provides a stable installation basis and a flat reference plane for the whole device. A conveying device is installed at one end of the bottom plate 1, which is specifically powered by a first servo motor 14 and driven by an output shaft of the first servo motor 14 to continuously operate a first conveying belt 15, so as to automatically convey the metal placed on the belt surface to the predetermined drilling processing position in the middle of the device.

[0053] A limit plate 3 is fixedly installed at the end of the first conveying belt 15 as a mechanical reference. A clamping and pushing mechanism is matched with the limit plate 3, which is arranged at the end of the conveying device, and the core functional component of the mechanism is an electro-hydraulic device 10 and a clamping plate 11 driven by the electro-hydraulic device 10. When the workpiece is sent to the end of the first conveying belt 15, the mechanism drives the clamping plate 11 to make a linear motion, and tightly presses the workpiece on the limit plate 3, so that the workpiece is firmly clamped.

[0054] In order to automatically detect the arrival of the workpiece, a proximity sensor is installed above the end of the first conveying belt 15. When the metal enters the sensing range of the proximity sensor, the proximity sensor can immediately generate a detection signal. The drilling structure is fixed above the bottom plate 1 through a support rod 4 through a support rod mounting plate 2, and the core includes a linear motor 5, a main shaft 7 driven by the linear motor 5, and a drill 8 installed at the front end of the main shaft 7. The linear motor 5 is responsible for providing precise downward feeding motion, and the main shaft 7 drives the drill 8 to rotate at high speed to perform drilling on the clamped workpiece.

[0055] Near the drilling station, an infrared sensor is installed to detect whether the workpiece stays in the original position after the drilling is completed. The core of the release device is a pneumatic cylinder 13, which is installed in a position such that the output end of the pneumatic cylinder 13 can act on the workpiece. When the infrared sensor detects the workpiece and sends a signal, the pneumatic cylinder 13 immediately acts to push the finished workpiece away from the clamping station, thereby completing the automatic unloading.

[0056] The whole working process is driven by sensor signals: the proximity sensor detects the feeding completion, and triggers the clamping and drilling; the infrared sensor detects the machining completion, and triggers the unloading. The execution mechanisms are electrically connected and sequentially controlled by a central controller, so that the whole process automation from automatic feeding, accurate positioning, firm clamping, automatic drilling to final automatic unloading is realized, and the technical problems of low efficiency and poor precision consistency in traditional manual operation are effectively solved.

[0057] As a further explanation of the utility model, the clamping and pushing mechanism comprises a first mounting plate 9, an electro-hydraulic device 10 and a clamping plate 11, the electro-hydraulic device 10 is fixedly installed on the first mounting plate 9, the first mounting plate 9 is installed on the bottom plate 1, the output end of the electro-hydraulic device 10 is connected with the clamping plate 11, and the electro-hydraulic device 10 is used for driving the clamping plate 11 to perform clamping or releasing actions, and the clamping plate 11 is matched with the limit plate 3 to clamp or release the metal.

[0058] The electric hydraulic device 10 is fixedly installed on the first mounting plate 9 through bolts, and the piston rod output end of the electric hydraulic device 10 is rigidly connected with the back center position of the clamping plate 11 through a flange. When the proximity sensor detects that the workpiece reaches the machining position, the control system sends an instruction to the electric hydraulic device 10, so that the piston rod of the electric hydraulic device 10 protrudes forward, drives the clamping plate 11 to move along the linear rail to the limiting plate 3, and tightly presses the workpiece between the clamping plate 11 and the limiting plate 3, so as to form a stable clamping state. After the drilling process is completed, the control system again instructs the piston rod of the electric hydraulic device 10 to retract, drives the clamping plate 11 to retreat, and thus the clamping of the workpiece is released, and preparation is made for subsequent unloading action. The mechanism provides a huge clamping force through hydraulic driving, ensures the absolute stability of the workpiece in the drilling process, effectively prevents the workpiece from being displaced or vibrated, and thus the drilling precision is ensured.

[0059] Referring to Figure 1 , as a further explanation of the utility model, the proximity sensor is fixedly installed on the first mounting plate 9.

[0060] The proximity sensor adopts an inductive proximity switch, is fixedly installed on the upper edge of the first mounting plate 9 through a dedicated sensor support, and the sensing probe thereof faces the first conveying belt 15. Specifically, the sensor support is fastened on the pre-processed mounting hole position of the first mounting plate 9 through two M4 inner hexagonal screws. The cable thereof is protected through a bellows and is connected into the control cabinet of the device and is connected with the digital quantity input module of the programmable logic controller PLC. When the first conveying belt 15 delivers the metal to the drilling position and enters the effective sensing area of the proximity sensor, the sensor can rapidly detect the existence of the metal object and immediately outputs a PNP normally open 24VDC signal to the PLC. After the PLC receives the input signal, the action instruction is sent to the electric hydraulic device 10 according to the preset program logic, so that the clamping process is automatically started. The installation mode ensures the timeliness and accuracy of detection, and is a key sensing link for realizing the full-automatic assembly line operation.

[0061] Referring to Figure 1 and Figure 2 , as a further explanation of the utility model, the releasing device comprises a second mounting plate 12 and a pneumatic cylinder 13, the pneumatic cylinder 13 is fixedly installed on the second mounting plate 12, and the output end of the pneumatic cylinder 13 corresponds to the side of the clamped workpiece, wherein the movement direction of the output end of the electric hydraulic device 10 is perpendicular to the movement direction of the output end of the pneumatic cylinder 13.

[0062] The second mounting plate 12 is made of steel plate and is fixed perpendicularly to the upper surface of the base plate 1 by M10 inner hexagonal screws, and the installation position thereof is accurately adjusted so that the front face thereof is parallel to the side of the workpiece that is clamped. The pneumatic cylinder 13 is a standard double-acting thin pneumatic cylinder of SC series, and the cylinder body is fastened to the central position of the second mounting plate 12 by a matched L-shaped mounting seat and M8 bolts. The output end of the piston rod of the pneumatic cylinder 13 is provided with a push plate made of polyurethane and is connected by screwing, the installation height of the push plate is accurately set so that the center line thereof is consistent with the height center of the workpiece when the workpiece is clamped, and when the piston rod is fully extended, the push plate can fully contact the side surface of the workpiece and push the workpiece away from the clamping position. The pneumatic cylinder 13 is connected to the electromagnetic valve group and the air source processing unit through a polyurethane air pipe, and the electromagnetic valve is controlled by the output point of the PLC. When the infrared sensor detects the workpiece after drilling, the PLC controls the corresponding electromagnetic valve to reverse, drives the piston rod of the pneumatic cylinder 13 to rapidly extend, and applies a smooth pushing force to the workpiece through the push plate to accurately push the workpiece into the second conveying belt 17, and the automatic unloading is completed. The structure realizes rapid and smooth pushing action by pneumatic driving, and the stability and accuracy of the working position of the pneumatic cylinder 13 are ensured by the independent installation of the second mounting plate 12.

[0063] Referring to Figure 3 , as a further explanation of the utility model, the infrared sensor is fixedly installed on the second mounting plate 12.

[0064] The infrared sensor adopts a diffuse reflection type photoelectric sensor and is fixedly installed on the upper portion of the second mounting plate 12 through a universal adjusting support. Specifically, the base of the universal adjusting support is fastened to the threaded holes pre-processed on the top side of the second mounting plate 12 through two M5 screws, and the sensor body is clamped in the locking clamp block at the end of the support. By loosening the locking nut, the pitch angle and horizontal direction of the sensor can be flexibly adjusted, so that the infrared beam emitting and receiving windows of the sensor are accurately aligned with the center area of the upper surface of the clamped workpiece, the optimal sensing distance is adjusted to 50-100 mm, and after the adjustment is completed, all locking devices are tightened to prevent loosening. The cable of the infrared sensor is connected to the control cabinet after being protected by a metal hose and is connected to another digital quantity input point of the PLC. When the drilling process is completed and the clamping and pushing mechanism is loosened, if the workpiece still stays in the original position, the modulated infrared light emitted by the infrared sensor is reflected by the surface of the workpiece and is detected by the receiver, and the sensor immediately outputs a high-level detection signal to the PLC. The PLC judges that the workpiece processing is completed and still in place, and after a short time (such as 0.5 seconds) according to the program logic, the electromagnetic valve of the pneumatic cylinder 13 is triggered to act, and the unloading process is started.

[0065] Referring to Figure 1 and Figure 2, as a further explanation of the utility model, the conveying device includes first servo motor 14, first conveyor belt 15, first roller 18 and first fixed plate 19;

[0066] The first servo motor 14 is fixedly installed on the bottom plate 1, and the output shaft thereof is drivingly connected with the first conveyor belt 15; the first conveyor belt 15 is internally provided with the first roller 18, and the two ends of the first roller 18 are fixed to the bottom plate 1 through the first fixed plate 19.

The first conveyor belt 15 is a rubber conveyor belt wrapped by double-layer canvas, and is uniformly provided with a plurality of first rollers 18 inside, the surfaces of the first rollers 18 are chrome-plated, and the two ends thereof are supported through deep groove ball bearings.

The mounting structure ensures that all the first rollers 18 are parallel to each other and the shaft lines thereof are on the same horizontal plane, provides uniform and stable support for the first conveyor belt 15, and effectively prevents the downward deformation of the middle part of the conveyor belt due to the weight of the workpiece. The first servo motor 14 receives pulse control signals from the PLC, can accurately control the start-stop, running speed and accurate positioning of the first conveyor belt 15, and thus accurately convey the metal to the drilling machining position at a preset speed.

[0068] Referring to Figure 2 and Figure 3 , as a further explanation of the utility model, the output device is installed on the bottom plate 1 and located at the side of the releasing device, and is used for receiving and conveying the pushed-off workpiece.

[0069] The output device includes a second servo motor 16, a second conveyor belt 17, a second roller 22 and a second fixed plate 20; the second servo motor 16 is fixedly installed, and the output shaft thereof is drivingly connected with the second conveyor belt 17; the second conveyor belt 17 is internally provided with the second roller 22, and the two ends of the second roller 22 are fixed to the bottom plate 1 through the second fixed plate 20.

The second conveying belt 17 adopts a non-slip pattern rubber belt, and a plurality of second rollers 22 with chrome-plated surfaces are arranged in parallel inside the second conveying belt 17, and the second rollers 22 are supported to rotate through deep groove ball bearings at both ends.

The second servo motor 16 receives the pulse control signal sent by the PLC, and can accurately control the running speed and direction of the second conveying belt 17. When the pneumatic cylinder 13 pushes the workpiece with completed drilling holes onto the second conveying belt 17, the second conveying belt 17 is immediately started to stably convey the workpiece to the next work station or the collection area, thereby realizing seamless connection of the automatic production line.
