Description

Technical Field

[0001] This invention relates to the field of metal circular workpiece processing technology, and in particular to a dual-axis drilling device. Background Technology

[0002] Currently, dual-axis drilling equipment is commonly used for batch processing of round workpieces, but existing equipment has many shortcomings:

[0003] 1. Poor automated feeding capability: Traditional equipment often requires manual feeding, and the workpieces are often in a chaotic state after being conveyed by simple material channels. It lacks automatic flipping and temporary storage buffer structures and cannot automatically turn flat workpieces into an upright state. The feeding cycle time does not match the drilling cycle time, which can easily cause material blockage and machine shutdown. Manual placement also has positioning errors and safety hazards.

[0004] 2. Insufficient accuracy in drilling lifting and transmission: Most drilling rigs use cylinders for lifting, making it difficult to precisely control the drilling depth; screw jacks have redundant transmission structures, belt pulley drives are prone to vibration and slippage, resulting in poor drilling accuracy, rapid belt wear, and frequent maintenance.

[0005] 3. Unstable workpiece clamping and transfer: The workpiece is pushed from only one side, and round workpieces are prone to tipping and shifting when pushed; there is no front and rear bidirectional clamping fit, and the workpiece is easily rotated by cutting force during drilling, resulting in poor hole position accuracy and machining consistency.

[0006] 4. Finished products and waste cannot be automatically separated: The frame is only equipped with a simple chip chute, and finished workpieces and metal scraps fall together, requiring manual sorting; it lacks a dual-channel conveyor and material distribution structure, and scrap is prone to getting stuck, requiring frequent cleaning and reducing production efficiency.

[0007] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a biaxial drilling device that has greater industrial application value. Summary of the Invention

[0008] To address the aforementioned technical problems, the present invention aims to provide a biaxial drilling device.

[0009] The present invention discloses a dual-axis drilling device, comprising a frame, a vertical frame fixed to the surface of the frame, two sets of lifting drilling machines for drilling are mounted on the vertical frame, a clamping plate for holding workpiece is provided directly below the drill bit of the drilling machine, two sets of push plate feeders are provided on the front side of the frame, the push plate feeders roll the workpiece down to the rotating mechanism through the inclined guide plate, the rotating mechanism drives the workpiece to rotate and slide down to the temporary storage mechanism, a push cylinder is fixed on the temporary storage mechanism, and a clamping cylinder is installed in the vertical frame, the push cylinder cooperates with the clamping cylinder to clamp the workpiece and move it into the clamping plate.

[0010] This dual-axis drilling device is equipped with a frame, with an externally fixed support. Two drilling machines capable of autonomously lifting and lowering to complete drilling operations are mounted on the support. Each drilling machine is equipped with a drill bit, and a clamping plate is placed below it to support and fix the workpiece. Two sets of pusher feeders are located at the front of the frame. The pusher feeders are equipped with inclined guide plates. The workpiece is slid and transported to the rotating mechanism by its own weight based on the slope of the guide plates. The rotating mechanism can adjust the workpiece's orientation and slide it to the temporary storage mechanism for storage. The temporary storage mechanism is equipped with a pusher cylinder, and a clamping cylinder is installed inside the support. The pusher cylinder and the clamping cylinder work together to simultaneously clamp and position the workpiece from both sides, and then push the workpiece to move it into the clamping plate for fixation.

[0011] Furthermore, a drilling rig mounting base is mounted on the surface of the upright frame via a slide rail slider. A drill bit rotating shaft is mounted on the surface of the drilling rig mounting base, and a drill bit is mounted at the end of the drill bit rotating shaft. A drive motor for driving the drill bit rotating shaft is mounted on the horizontal plate of the drilling rig mounting base. The drill bit rotating shaft and the drive motor are connected by a belt and pulley transmission. An electric lead screw pair is mounted at the top of the upright frame. The screw of the electric lead screw pair engages with the threaded sleeve on the inner side of the drilling rig mounting base. The electric lead screw pair is used to drive the drilling rig mounting base to move up and down along the slide rail.

[0012] The drill rig mounting base is slidably assembled on the outer wall of the support frame using a sliding rail slider. The drill bit rotating shaft is mounted on the drill rig mounting base, and the drill bit is mounted at the end of the rotating shaft to perform drilling and cutting operations. A drive motor is fixedly installed on the horizontal plate of the drill rig mounting base. The drive motor transmits power through a belt and pulley to drive the drill bit rotating shaft to rotate continuously. An electric lead screw pair is installed on the top of the support frame. The screw of the electric lead screw pair can mesh with the screw sleeve set on the inner side of the drill rig mounting base. The power output of the electric lead screw pair can drive the drill rig mounting base to slide up and down along the sliding rail to adjust the overall height of the drill bit.

[0013] Furthermore, the rotating mechanism includes a rotating support fixed to the surface of the frame, a rotating cylinder mounted on the surface of the rotating support, a right-angled material support plate mounted on the rotating rod of the rotating cylinder, and a recessed limiting groove provided on the surface of the material support plate for limiting the workpiece.

[0014] The rotating mechanism is securely mounted on the frame with a rotating support base. A rotating cylinder is mounted on top of the rotating support base to provide rotational power. A right-angled material support plate is fixed on the rotating rod of the rotating cylinder to support the workpiece. The material support plate has an inwardly recessed limiting groove, which can constrain and block the workpiece placed on the material support plate to prevent the workpiece from shifting or slipping during rotation and to ensure the stability of the workpiece position during posture transformation.

[0015] Furthermore, the temporary storage mechanism includes a guide sleeve located on one side of the limiting groove on the surface of the material support plate. The guide sleeve is wider at the top and narrower at the bottom. The opening at the lower end of the guide sleeve is located on the upper side of two parallel guide plates. After the material support plate is flipped, the flat workpiece is vertically guided from the guide sleeve between the guide plates. The guide plates are fixed on the flat plate at the upper end of the temporary storage bracket. A vertically upward cylinder mounting plate is provided at the tail end of the temporary storage bracket. The telescopic rod of the pushing cylinder passes through the through hole of the cylinder mounting plate and is fixed with a pushing block with a groove on its surface.

[0016] The temporary storage mechanism is equipped with a guide sleeve placed next to the limiting groove of the material support plate. The guide sleeve, with its shape that is wider at the top and narrower at the bottom, can smoothly receive the workpiece and straighten its placement. The opening at the lower end of the guide sleeve faces the top of two parallel guide plates. When the material support plate flips, it can adjust the originally flat workpiece to a vertical position and send it into the middle position between the two guide plates through the guide sleeve. The guide plates are fixed to the flat plate at the upper end of the temporary storage bracket to stably support the workpiece. A cylinder mounting plate is set vertically at the tail of the temporary storage bracket to play a supporting and fixing role. The telescopic rod of the push cylinder passes through the through hole reserved in the cylinder mounting plate. The end of the telescopic rod is fixed with a push block with a groove structure. The push block can conform to the outer wall of the workpiece to complete the pushing action.

[0017] Furthermore, the clamping cylinder is fixed inside the upright frame by a clamping bracket. A push rod guide sleeve is fixed on the surface of the upright frame, and the push rod guide sleeve is used for the push rod to pass through. The surface of the push rod has a groove.

[0018] The clamping cylinder is stably placed in the internal space of the frame with the help of the clamping bracket. The push rod guide sleeve is fixedly installed on the outer wall of the frame. The push rod guide sleeve allows the push rod to pass through and guides and constrains the movement trajectory of the push rod. The push rod with grooves on its surface can move synchronously with the clamping cylinder, and cooperate with the corresponding components to complete the workpiece clamping and positioning work.

[0019] Furthermore, the clamping plate is through-shaped, and the surface of the frame is provided with multiple through slots for the falling of waste chips. The inside of the frame is provided with a chip removal mechanism and a material conveying mechanism, which are arranged alternately. The ends of the chip removal mechanism and the material conveying mechanism extend to both sides of the frame. Waste chip carts and material carts are respectively provided below the chip removal mechanism and the material conveying mechanism.

[0020] The clamping plate is designed as a continuous design to facilitate workpiece placement and waste chip drop. Multiple through slots are opened on the surface of the frame to allow waste chips generated during processing to fall downwards. The frame is equipped with both a chip removal mechanism and a material conveying mechanism. The chip removal mechanism and the material conveying mechanism are interspersed to achieve separate conveying. The ends of the chip removal mechanism and the material conveying mechanism extend outwards to both sides of the frame. A waste chip cart is placed below the chip removal mechanism to collect the falling metal waste chips. A material cart is provided below the material conveying mechanism to collect the finished workpieces after processing. This achieves separate collection of waste chips and workpieces, preventing them from mixing together.

[0021] Furthermore, a guide frame with a wider top and a narrower bottom is provided above the intersection of the chip removal mechanism and the material conveying mechanism. A swingable dividing plate is provided in the middle of the guide frame. The lower end of the dividing plate is rotatably mounted on the connecting rod on the lower opening side of the guide frame via a hinge. An opening and closing cylinder mounting bracket is fixed on the upper side of the guide frame. An opening and closing cylinder is fixed on the mounting bracket. The telescopic rod of the opening and closing cylinder passes through the mounting bracket and is fixed to a connecting block with an opening. A pull block with a guide groove is fixed on the surface of the dividing plate. The pull block is inserted into the opening of the connecting block, and a pin fixes the connecting block in the guide groove of the pull block.

[0022] The guide frame is positioned above the area where the chip removal mechanism and the material conveying mechanism intersect. The guide frame has a wider top and narrower bottom structure to collect falling materials. A swaying distribution plate is mounted in the middle of the guide frame to switch the material flow direction. The lower end of the distribution plate is hinged to a connecting rod on the side of the lower opening of the guide frame, ensuring flexible swaying. A cylinder mounting bracket is fixed to the upper part of the guide frame, supporting the cylinder. The telescopic rod of the cylinder passes through the mounting bracket and connects to a connecting block with an opening. A pull block with a guide groove is fixed to the outer wall of the distribution plate. The pull block is embedded in the opening of the connecting block, and a pin is used to limit the connection block's movement within the pull block's guide groove. When the cylinder extends or retracts, it pulls the connecting block, causing the pull block to deflect the distribution plate, thus switching the material's falling path and allowing the material to fall into either the chip removal mechanism or the material conveying mechanism.

[0023] By means of the above-described solution, the present invention has at least the following advantages: 1. This device is equipped with a pusher plate feeder, guide plate, rotating mechanism and temporary storage mechanism to complete automated feeding. The workpiece can be automatically conveyed, rotated and temporarily stored and buffered. There is no need for manual placement and correction of the workpiece, eliminating the positioning deviation and safety hazards caused by manual operation. The feeding cycle can be matched with the drilling processing cycle, effectively avoiding the problem of material blockage and machine stoppage, and greatly improving the degree of automation of feeding and production continuity.

[0024] 2. The electric screw pair drives the drilling rig mounting base to lift and lower, and the drive motor and belt pulley drive the drill bit to rotate. The lifting and lowering adjustment is smooth and precise, which can adapt to the processing needs of different workpieces. The transmission structure has low vibration and is not prone to loss of rotation. The drilling accuracy is higher, while reducing belt wear and reducing the frequency of daily equipment maintenance.

[0025] 3. By relying on the bidirectional cooperation of the pusher cylinder and the clamping cylinder to push and clamp the workpiece, the workpiece can be stably sent into the clamping plate. During the processing, the workpiece is not easy to tilt, deviate or rotate, ensuring that the workpiece is firmly clamped and improving the hole position accuracy and the consistency of the processing of the whole batch of workpieces.

[0026] 4. The chip removal mechanism and material conveying mechanism are arranged in an alternating manner inside the frame. Combined with components such as guide frames, swingable dividing plates, and opening and closing cylinders, the material is automatically diverted. Processing waste and finished workpieces fall into the waste car and material car respectively, eliminating the need for manual sorting. At the same time, waste can be discharged in time, avoiding metal fragments from getting stuck in various moving parts, reducing equipment cleaning downtime, and effectively improving overall processing efficiency.

Detailed Implementation

[0030] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0031] See Figures 1-3 After being output by the pusher plate feeder 5, the workpiece slides along the inclined guide plate 6 to the rotating mechanism 7 by its own weight. The rotating mechanism 7 drives the workpiece to change its orientation and slide it to the temporary storage mechanism 8 for temporary storage and buffering. The pusher cylinder 9 mounted on the temporary storage mechanism 8 extends to push the workpiece, forming a bidirectional clamping and positioning with the clamping cylinder 10 arranged inside the upright frame 2. Together, they accurately transfer the workpiece to the clamping plate 4 for clamping and positioning. Subsequently, the two sets of lifting drilling machines 3 mounted on the upright frame 2 descend to perform dual-station synchronous drilling on the workpiece inside the clamping plate 4. The entire process is integrated and automated by the frame 1, without the need for manual intervention in workpiece transfer and attitude correction. The dual-station synchronous operation improves processing capacity. After the workpiece is continuously and orderly transferred by multiple mechanisms, the positioning accuracy is stable. The bidirectional cylinder clamping can avoid workpiece offset and overturning problems. The temporary storage mechanism 8 buffers the process cycle and effectively prevents material blockage and equipment standby.

[0032] The pusher plate feeder 5 adopts a conventional structure, which can realize the cyclical pushing of workpieces upward.

[0033] The clamping plate 4 adopts a double clamping head structure, with the two clamping heads set perpendicularly to the pushing cylinder 9 and the clamping cylinder 10.

[0034] When the equipment performs drilling operations, the electric lead screw 15 at the top of the stand 2 drives the drilling rig mounting base 11 through a screw and a screw sleeve inside the mounting base 11, causing the mounting base 11 to move vertically linearly along the stand 2 via a slide rail slider. The drive motor 14 on the horizontal plate of the drilling rig mounting base 11 outputs torque, which is transmitted to the drill bit rotating shaft 12 via a belt and pulley drive pair. This drives the drill bit 13 mounted at the end of the drill bit rotating shaft 12 to rotate at high speed, and then moves down with the drilling rig mounting base 11 to complete the cutting and drilling. After the machining is completed, the electric lead screw 15 drives the drilling rig mounting base 11 in the reverse direction. The lifting of the base 11 enables the retraction of the drill bit 13. This transmission lifting structure relies on the electric lead screw pair 15 to achieve closed-loop precise control of the feed stroke. The belt and pulley drive has a buffering and shock absorption effect, which can reduce the vibration and impact generated by high-speed cutting and effectively ensure the rotational stability of the drill bit 13 and the drilling dimensional accuracy. The slide rail slider guide structure constrains the movement trajectory of the drill mounting base 11 and eliminates feed deviation. The overall transmission layout is integrated on the drill mounting base 11, which is compact and easy to maintain. Compared with the pneumatic lifting structure, it can achieve precise feed to any depth and reduce the scrap rate.

[0035] See Figure 4 The workpiece slides down to the material support plate 18 of the rotating mechanism 7 above the frame 1, where it is positioned and constrained by the recessed limiting groove. The rotating support base 16 provides a rigid mounting reference for the rotating cylinder 17. The rotating cylinder 17 outputs rotational torque to drive its own rotating rod to rotate the right-angled material support plate 18 at a fixed angle, thereby changing the workpiece's placement posture. After the posture adjustment is completed, the workpiece slides out along the material support plate 18 and flows to the next process. The rotating support base 16 can ensure that the rotating cylinder 17 is installed stably without shaking during operation. The limiting groove can limit the radial displacement of the workpiece, preventing the workpiece from shifting or falling off during the rotation. The rotating cylinder 17 can precisely control the rotation angle, realizing the automatic conversion of the workpiece from a flat posture to a vertical posture without the need for manual correction of the workpiece orientation. The overall structure has a high degree of integration, and the posture conversion process is stable and reliable, effectively matching the conveying rhythm of the preceding and following processes and improving the automation level of the entire process.

[0036] See Figure 5 and Figure 6After the material support plate 18 completes its flipping action, the workpiece, lying flat, falls smoothly into the guide sleeve 19 beside the limiting groove. The guide sleeve 19, with its tapered guide structure (wider at the top and narrower at the bottom), straightens the workpiece's posture. The workpiece then falls vertically through the lower opening of the guide sleeve 19 between two parallel guide plates 20 for temporary storage. The guide plates 20 are rigidly fixed by the flat plate at the upper end of the temporary storage bracket 21. The cylinder mounting plate 22, vertically arranged at the tail of the temporary storage bracket 21, provides a mounting carrier for the pushing cylinder 9. The telescopic rod of the pushing cylinder 9 passes through the through hole of the cylinder mounting plate 22 and drives the pusher with a grooved end. The material block 23 makes a linear feed motion, and the pusher block 23 pushes the workpiece to the next station for transfer by adhering to the side wall of the workpiece. The entire temporary storage mechanism 8 relies on the guide sleeve 19 and the guide plate 20 to complete the workpiece posture correction and process buffering and material storage, which can resolve the difference in the cycle time between feeding and drilling and avoid material blockage. The groove structure of the pusher block 23 can realize the workpiece adhering and limiting, and there is no slippage or offset during the pushing process. The temporary storage bracket 21 and the cylinder mounting plate 22 are integrated and have strong rigidity, which ensures that the pushing cylinder 9 pushes smoothly, greatly reducing the need for manual assistance in shaping and transfer, and improving the automated continuous operation capability of the equipment.

[0037] See Figure 7After the material support plate 18 completes its flipping action, the workpiece, lying flat, falls into the guide sleeve 19 beside the limiting groove. The guide sleeve 19, with its tapered guide structure (wider at the top and narrower at the bottom), straightens the workpiece's posture. The workpiece then falls vertically through the lower opening of the guide sleeve 19 between two parallel guide plates 20 for temporary storage. The guide plates 20 are rigidly fixed by the flat plate at the upper end of the temporary storage bracket 21. The workpiece first falls onto the temporary storage bracket 21 to await transfer. The cylinder mounting plate 22, vertically arranged at the tail of the temporary storage bracket 21, provides a mounting carrier for the pushing cylinder 9. The telescopic rod of the pushing cylinder 9 extends through... The cylinder 9 passes through the through hole in the mounting plate 22 and drives the pusher block 23 with a grooved end to make a linear feed motion. At the same time, the clamping cylinder 10 is rigidly assembled with the clamping bracket 24 and arranged inside the stand 2. The pusher cylinder 9 first drives the push rod 26 to move axially forward along the push rod guide sleeve 25 fixed to the outer wall of the stand 2, so that the push rod 26 with a grooved surface fits against one side wall of the workpiece. Then, the clamping cylinder 10 drives the pusher block 23 to fit against the other side wall of the workpiece. The two work together to complete the bidirectional clamping and positioning of the workpiece. The pusher cylinder 9 and the clamping cylinder 10 move synchronously to move the firmly clamped workpiece to the clamping position. The internal clamping of the holding plate 4 is completed. After it is in place, the pusher cylinder 9 and the clamping cylinder 10 drive the push rod 26 and the pusher block 23 to retract and reset, respectively, thus completing the automated feeding process for a single workpiece. The entire temporary storage mechanism 8 relies on the guide sleeve 19 and the guide plate 20 to complete the workpiece posture correction and process buffering and material storage, which can resolve the difference in feeding and drilling cycle time and avoid material blockage. The groove structure of the pusher block 23 and the push rod 26 can realize the workpiece fitting and limit, and there is no slippage or offset during the pushing and clamping process. The integrated assembly structure of the temporary storage bracket 21 and the cylinder mounting plate 22 has strong rigidity and ensures the pusher cylinder 9. The clamping cylinder 10 pushes and clamps smoothly. The push rod guide sleeve 25 effectively eliminates the feed offset and radial runout of the push rod 26. The groove on the outer wall of the push rod 26 can form a fitting and limiting structure with the outer wall of the workpiece, increasing the contact friction and preventing the workpiece from rotating circumferentially during drilling and cutting. The two-way cooperative clamping mode improves the workpiece clamping stability and reduces hole machining deviation. The overall structure is integrated around the frame 2, occupying a compact space. The separate design of the guide and clamping components facilitates later disassembly and maintenance, greatly reducing the need for manual auxiliary shaping and transfer, and improving the automated continuous operation capability of the equipment.

[0038] See Figure 8After the workpiece is drilled inside the clamping plate 4, it is released from clamping constraints and falls directly down through the through-type clamping plate 4 onto the surface of the material conveying mechanism 28 arranged inside the frame 1. The metal cutting waste generated during the machining process passes through the clamping plate 4 and falls down through multiple slots opened on the surface of the frame 1. The chip removal mechanism 27 and the material conveying mechanism 28 are arranged alternately inside the frame 1, and the ends of the two types of mechanisms extend outward to both sides of the frame 1. The falling waste falls into the chip removal mechanism 27 and is conveyed by it to the outside of the frame 1, and finally falls into the waste chip cart 29 below the chip removal mechanism 27 for collection. The finished workpiece is then collected along with the material. The conveying mechanism 28 transports materials to the other side of the frame 1. The material cart 30 that falls below the material conveying mechanism 28 is collected in a unified manner. The through-type clamping plate 4, combined with the through slot of the frame 1, enables the immediate falling of processing waste, avoiding the accumulation of debris inside the clamping plate 4 and affecting the positioning accuracy of the workpiece. The chip removal mechanism 27 and the material conveying mechanism 28 are arranged alternately and independently to achieve dual-channel separation and conveying of finished workpieces and metal waste. There is no need for manual sorting to distinguish between workpieces and waste. The separate storage structure of the waste cart 29 and the material cart 30 facilitates centralized transfer and cleaning, effectively reducing the frequency of equipment downtime for cleaning and improving the continuous automated processing time and production efficiency of the whole machine.

[0039] The chip removal mechanism 27 is a traditional belt conveyor mechanism, which can realize the recycling and discharge of waste chips.

[0040] The material conveying mechanism 28 is a traditional chain plate conveying mechanism, with vertical plates set on the corresponding chain plates to enable the arrangement of workpieces.

[0041] See Figure 9 and Figure 10During the drilling operation, the opening and closing cylinder 34, carried by the cylinder mounting bracket 33, retracts. The telescopic rod of the cylinder 34 passes through the cylinder mounting bracket 33, causing the connecting block 35 with an opening to move. The connecting block 35 forms a movable linkage structure with the guide groove of the pull block 36 by means of a pin. Pulling the pull block 36 with the guide groove drives the material distribution plate 32 to swing and flip around the connecting rod at the lower opening side of the guide frame 31 with the hinge as the fulcrum. The upper end of the material distribution plate 32 is attached to the upper part of the guide frame 31, completely opening the lower opening of the guide frame 31. The metal chips generated during processing flow downward through the guide frame 31, which is wider at the top and narrower at the bottom, to the chip removal mechanism 27 for centralized chip removal. After the drilling process is completed, the opening and closing cylinder 34 extends and pushes the connecting block 35 forward. Through the transmission of the pull block 36, the material distribution plate 32 swings in the opposite direction and blocks the lower opening of the guide frame 31. Then the clamping plate 4 is released. After processing, the workpiece falls to the surface of the distribution plate 32 and slides along the guide of the distribution plate 32 to the material conveying mechanism 28. The guide frame 31 can gather the falling material to prevent splashing. The distribution plate 32 uses the opening and closing cylinder 34 to realize the adaptive switching of the flow channel under working conditions, accurately distinguishing the falling path of waste and finished workpiece, and preventing workpieces and waste from mixing. The connecting block 35 and the pulling block 36 are connected by guide groove pins to compensate for the swing stroke deviation of the distribution plate 32. The hinge structure ensures that the flipping action of the distribution plate 32 is smooth and without jamming. The opening and closing cylinder mounting bracket 33 provides a stable installation reference for the opening and closing cylinder 34. The entire diversion structure is integrated above the intersection area of ​​the chip removal mechanism 27 and the material conveying mechanism 28, eliminating the need for manual sorting and separation of workpieces and waste, reducing equipment downtime for cleaning, and continuously ensuring the automated operation of the production line.

[0042] The working principle of this invention is as follows: The entire machine is equipped with a PLC controller and an air pump as a unified control unit for the pneumatic and actuation mechanisms. Two processing units synchronously execute a dual-workpiece automated processing flow. The PLC outputs signals according to a preset timing sequence to control the air pump, providing air power to each cylinder. The workpiece is continuously output from the pusher plate feeder 5 and continuously circulated along the inclined guide plate 6 by its own weight to the rotating mechanism 7. The PLC trigger signal drives the rotating cylinder 17 to actuate. The rotating mechanism 7 drives the material support plate 18 to flip, adjusting the horizontally lying workpiece to a vertical position. After being straightened by the guide sleeve 19, it falls onto the temporary storage bracket 21 of the temporary storage mechanism 8 for buffering and positioning. The PLC then synchronously issues action commands, and the pushing cylinder 9 and the clamping cylinder 10 start simultaneously. The pushing cylinder 9 drives the pushing block 23 to abut against one side wall of the workpiece, while the clamping cylinder 10 drives the push rod 26 to feed along the push rod guide sleeve 25 to fit against the other side wall of the workpiece. The two clamp the workpiece in both directions and push it into the clamping plate 4 simultaneously to achieve precise clamping. After the workpiece positioning detection sensor sends a feedback signal to the PLC, the PLC controls the pushing cylinder 9 and the clamping cylinder 10 to simultaneously depressurize and reset. The electric lead screw pair 15 at the top of the upright frame 2 receives the feed signal from the PLC and drives the drilling rig mounting base 11 to feed downward along the slide rail slider. The drive motor 14 then... The belt pulley drive drives the drill bit 13 at the end of the drill bit rotating shaft 12 to rotate at high speed to complete the drilling operation. During the drilling process, the PLC controls the opening and closing cylinder 34 to retract, pulling the material distribution plate 32 to flip and open the lower opening of the guide frame 31. The metal scrap generated during processing passes through the through-type clamping plate 4 and the through groove on the surface of the frame 1 and falls into the guide frame 31, which is directly guided to the chip removal mechanism 27 and transported to the waste chip cart 29 for centralized collection. After the drilling process is completed, the electric lead screw 15 drives the drill mounting base 11 to lift and retract the tool. The PLC switches the output state of the opening and closing cylinder 34 to extend it, pushing the material distribution plate 32 to swing in the opposite direction to block the guide frame 31. With the lower opening, the clamping plate 4 releases its clamping constraint on the finished workpiece, which falls downward onto the surface of the distribution plate 32 and is guided along the plate surface into the material conveying mechanism 28. The material conveying mechanism 28 then transports the workpiece to the material cart 30 to complete the finished product collection. After all actions are completed, the PLC automatically issues loading instructions in a cyclical manner. The two processing units operate independently and synchronously. Relying on the unified timing scheduling of the PLC and the centralized air supply of the air pump, the entire process is achieved through unmanned, synchronous, automated, and continuous production of dual workstations. The actions of each process are interlocked, effectively avoiding faults such as material blockage, workpiece slippage, and processing misalignment, and greatly improving the stability and production efficiency of batch processing.
