Description

Technical Field

[0001] This utility model belongs to the field of cutting tool processing technology, specifically relating to a drilling mechanism for nail holes. Background Technology

[0002] In existing precision drilling equipment, automated drilling operations using precision tools face multiple technical bottlenecks. Traditional drilling devices generally employ mechanical chuck-type positioning structures. Their complex linkage mechanisms not only increase the difficulty of equipment debugging but also easily lead to positioning accuracy deviations due to mechanical wear during high-frequency rotation, causing nail hole position shifts. Especially in multi-station continuous processing scenarios, the uniformity of tool clamping force is difficult to control, frequently resulting in inconsistent drilling depths caused by tool loosening. Consequently, the automation level of the unloading process in existing technologies has significant shortcomings: traditional unloading mechanisms mostly use fixed-stroke push-rod structures, unable to adaptively adjust according to tool size and drilling position, and are prone to tool damage due to uneven contact force during unloading. Utility Model Content

[0003] The purpose of this utility model is to provide a hole-punching mechanism for nailing rice, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rice-drilling mechanism, comprising:

[0005] The stabilizing base has a rotatable punching turntable at its upper end for placing and rotating the cutting tools in sequence to perform nail drilling. The upper end of the punching turntable has a cutting tool clamping plate for placing the cutting tools inside and positioning them, and clamping them in a pneumatic manner. A collection frame is provided on one side of the bottom of the punching turntable for adsorbing and collecting the waste material in the drilling process.

[0006] The upright has a pneumatic plate on one side of its upper end for impacting and punching nails and pressing them down for positioning. The lower end of the pneumatic plate has an impact punching plate with the same shape as the inner cavity of the cutter clamp for impacting and punching nails. On the other side of the stabilizing seat, a pneumatic suction plate is provided through the stabilizing upright for pneumatically adsorbing and unloading the cutter after impact punching.

[0007] Preferably, a servo motor is provided at the center of the end of the stabilizing seat, and the rotating shaft of the servo motor is fixedly connected to the middle of the lower surface of the drilling turntable. Suction devices and collection boxes connected to the output end of the suction devices are provided on both sides of the servo motor through pipes. The suction pipe connected to one end of the suction device extends into the inner cavity of the receiving frame to solve the problem of hole position offset during multi-station processing. The negative pressure linkage design of the suction device and the collection box avoids the interference of debris residue on the worktable to subsequent processes.

[0008] Preferably, the tool positioning cavity of the tool clamping plate is provided with three through holes that extend to the bottom of the drilling turntable and are perpendicular to the receiving frame, which facilitates the adsorption of waste materials. Cylinder A is provided on both sides of one end of the tool clamping plate, and a movable clamping plate is provided at one end of the cylinder A to cooperate with the tool clamping plate to clamp and position the drilling tool. The clamping force can be automatically adjusted according to the tool size to ensure that the clamping uniformity error is less than 5%, and to avoid tool loosening and drilling depth deviation caused by uneven clamping force.

[0009] Preferably, the bottom end of the movable clamping plate is provided with a guide groove at the position corresponding to the drilling turntable, and a movable block fixedly connected to the lower end face of the movable clamping plate slides in the guide groove through a guide rod. This effectively avoids the problem of tool tilting or jamming caused by installation errors in traditional rigid connection structures, and improves the reliability of the positioning mechanism.

[0010] Preferably, a rotating motor is provided in the cavity at the end of the stabilizing pole, and a rotating rod extending to one side is fixed on the rotating shaft of the rotating motor. A cylinder B is provided on the lower end face of the rotating rod, and one end of the cylinder B is fixed at the center position of the upper end face of the pneumatic suction plate, so as to avoid mechanical contact force damage to the surface of the tool during the unloading process, which is especially suitable for the automated unloading of high-precision coated tools.

[0011] Preferably, the adsorption cavity of the pneumatic suction plate is connected to an air suction hose, and the other end of the air suction hose is connected to the air suction port of the air suction pump fixed on the rotating rod. The bottom surface of the adsorption cavity of the pneumatic suction plate is uniformly perforated with air suction holes to ensure that the blade is subjected to uniform force during the unloading process.

[0012] Preferably, a top plate is fixed to one side of the upper end of the upright, and a cylinder C is provided at the bottom of the top plate. One end of the cylinder C is fixed to the upper surface of the pneumatic plate. The lower surface of the impact drilling plate at the bottom of the pneumatic plate is provided with an impact drilling head corresponding to the through hole. During drilling, a closed processing space is formed, which effectively prevents debris from splashing and improves the stability of the drilling process.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are: the nail hole punching mechanism,

[0014] A servo motor drives the drilling turntable to achieve precise indexing and positioning. This, combined with a cylinder A-driven moving clamping plate and tool clamping plate, forms a pneumatic clamping system. This system automatically adjusts the clamping force according to the tool size, reducing clamping uniformity errors. The sliding fit between the guide groove and guide rod further ensures the linear motion accuracy of the clamping plate, fundamentally solving the problems of hole position misalignment and uneven clamping force caused by wear in traditional mechanical jaws, thus significantly improving the consistency of drilled holes.

[0015] By aligning three through holes vertically with the receiving frame, a direct channel for waste adsorption is constructed. Combined with the negative pressure linkage mechanism between the suction device and the collection box, efficient collection of metal shavings is achieved, completely solving the problem of shavings residue on the worktable caused by traditional gravity discharge or brush cleaning methods. This structure simultaneously adsorbs waste during the drilling process, preventing shavings from accumulating and interfering with subsequent processes, thus improving the cleanliness of the processing environment and the reliability of the equipment.

[0016] By integrating a rotating motor, cylinder B, and suction pump (with uniform suction hole layout) into a moving suction plate, a non-contact negative pressure adsorption unloading system is formed. Compared with the traditional fixed stroke push rod structure, it can adapt to the unloading position of different sized cutters, reduce unloading time, and avoid mechanical contact damage to the cutter surface, thereby further improving the unloading speed.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides a technical solution: a rice-drilling mechanism, comprising:

[0025] The stabilizing base 1 ensures the relative positional accuracy of each component during operation, reducing processing errors caused by vibration or displacement. Its robust material and reasonable design dimensions can withstand various forces generated during drilling, ensuring stable overall equipment operation. The upper end of the stabilizing base 1 is equipped with a drilling turntable 2 for sequentially placing and rotating the cutting tools for meter drilling, realizing the sequential positioning and rotation of the cutting tools, facilitating meter drilling operations at different workstations. Through regular rotation, the cutter placed in the cutter clamp 3 can be accurately delivered to the impact drilling and unloading stations. The upper end of the drilling turntable 2 is provided with a cutter clamp 3, which is used to fix the cutter after the cutter is placed inside and positioned by pneumatic means. The cutter clamp 3 is installed on the upper end of the drilling turntable 2 and rotates synchronously with the drilling turntable 2. Cylinders A13 are installed on both sides of one end of the cutter clamp 3. The piston rod of the cylinder A13 is connected to the moving clamp 14 to realize the clamping action of the cutter. The three through holes 12 in the cutter positioning cavity of the cutter clamp 3 extend vertically to the bottom of the drilling turntable 2 and correspond to the receiving frame 4, which facilitates the falling and adsorption of waste. A receiving frame 4 is provided on one side of the bottom of the drilling turntable 2 for adsorbing and collecting the waste in the drilling of the cutter.

[0026] The receiving box 4 is used to collect waste generated during the drilling process, effectively preventing waste from scattering everywhere, maintaining a clean working environment, and avoiding damage to other parts of the equipment or interference with subsequent processing steps. It works in conjunction with the suction device 10 to achieve efficient waste collection and improve the automation and continuity of the production process.

[0027] The upright post 5 provides the mounting and support foundation for the pneumatic plate 6, ensuring sufficient stability during impact drilling and clamping positioning operations. The height and strength design of the upright post 5 meets the working requirements of the pneumatic plate 6 under different working conditions, guaranteeing the accuracy and reliability of the impact drilling process. A pneumatic plate 6 is pneumatically mounted on one side of the upper end of the upright post 5 for impact drilling and clamping positioning of the nail. Driven by cylinder C24, it can achieve rapid and precise up-and-down movement, impact drilling the nail and clamping the positioning tool. The impact drilling plate 7 on its lower end face has the same shape as the inner cavity of the tool clamp 3, effectively ensuring the accuracy and consistency of drilling and preventing tool failure due to drilling position deviation. Furthermore, the impact drilling plate 7 on the lower end face of the pneumatic plate 6, with the same shape as the inner cavity of the tool clamp 3, allows for better positioning and coordination with the tool during impact drilling, ensuring the accuracy of the drilling position and the drilling quality. Its structural design can withstand large impact forces, ensuring that it is not easily damaged in frequent impact drilling operations and extending its service life. On the other side of the stabilizing seat 1, a pneumatic suction plate 8 is provided for air pressure adsorption unloading of the tool after impact drilling through the stabilizing upright 26. The tool after impact drilling is unloaded by air pressure adsorption.

[0028] The upper end of the stabilizing base 1 is rotatably connected to the punching turntable 2, enabling the punching turntable 2 to rotate smoothly in a circular motion above it. A servo motor 9 is installed at the center of the end of the stabilizing base 1, and the shaft of the servo motor 9 is fixedly connected to the middle of the lower surface of the punching turntable 2, providing a power source for the rotation of the punching turntable 2. On the other side of the stabilizing base 1, a lifting connection is established between the stabilizing upright 26 and the pneumatic suction plate 8, enabling the pneumatic suction plate 8 to perform precise lifting and lowering movements under the guidance of the stabilizing upright 26.

[0029] A servo motor 9 is located at the center of the end of the stabilizer 1, which can precisely control the rotation speed and angle of the drilling turntable 2, ensuring the positioning accuracy of the tool between different workstations. It features fast response, smooth operation, and high control precision. The rotation parameters of the drilling turntable 2 can be flexibly adjusted according to the processing requirements, improving processing efficiency and product quality. The shaft of the servo motor 9 is fixedly connected to the center of the lower surface of the drilling turntable 2. Suction devices 10 and a collection box 11 connected to the output end of the suction devices 10 via pipes are located on both sides of the servo motor 9. The suction devices 10 and the collection box 11 work together to efficiently collect and transport waste material in the receiving frame 4 through negative pressure adsorption. This allows for quick and thorough cleaning of waste material generated during the drilling process, maintaining a clean working environment, reducing manual cleaning workload, and improving the automation and continuity of the production process. The suction pipe connected to one end of the suction device 10 extends into the inner cavity of the receiving frame 4.

[0030] The tool clamping plate 3 has three through holes 12 in its tool positioning cavity, which extend to the bottom of the drilling turntable 2 and are perpendicular to the receiving frame 4, facilitating the adsorption of waste material. Cylinders A13 are installed on both sides of one end of the tool clamping plate 3, and a movable clamping plate 14, which cooperates with the tool clamping plate 3 to clamp and position the drilling tool, is located at one end of each cylinder A13. Cylinder A13 can quickly and accurately control the movement of the movable clamping plate 14, realizing the clamping and releasing action of the tool. The movable clamping plate 14, in cooperation with the tool clamping plate 3, can automatically adjust the clamping force according to the size and shape of the tool, ensuring the stability of the tool during the drilling process and preventing the tool from loosening due to insufficient clamping force or being damaged due to excessive clamping force.

[0031] Guide grooves 15 are provided at the bottom of the movable clamping plate 14 corresponding to the position of the drilling turntable 2. Within each guide groove 15, a movable block 16, fixedly connected to the lower end face of the movable clamping plate 14, slides through a guide rod. The cooperation of the guide grooves 15, guide rods, and movable blocks 16 provides precise guidance for the movement of the movable clamping plate 14, ensuring that it moves smoothly and linearly under the drive of the cylinder A13, avoiding wobbling or deviation, thereby improving the accuracy and stability of tool clamping. Simultaneously, this structure reduces friction during the movement of the movable clamping plate 14, extending the service life of the equipment.

[0032] A rotary motor 17 is installed in the cavity at the end of the stabilizing pole 26, and a rotating rod 18 extending to one side is fixed on the shaft of the rotary motor 17. A cylinder B19 is installed on the lower end face of the rotating rod 18, and one end of the cylinder B19 is fixed at the center position of the upper end face of the pneumatic suction plate 8. The rotary motor 17 can drive the rotating rod 18 to rotate, thereby enabling the cylinder B19 connected to the lower end face of the rotating rod 18 and the pneumatic suction plate 8 to rotate between different positions, realizing the adsorption and unloading operation of the tools at different workstations. The cylinder B19 is used to control the up and down movement of the pneumatic suction plate 8, so that it can accurately approach and move away from the tools, realizing an efficient unloading process.

[0033] A suction hose 20 is connected through the suction cavity of the pneumatic suction plate 8, and the other end of the suction hose 20 is connected to the suction port of the suction pump 21 fixed on the rotating rod 18. Suction holes 22 are evenly distributed through the bottom surface of the suction cavity of the pneumatic suction plate 8. The suction pump 21 provides a stable negative pressure to the suction cavity of the pneumatic suction plate 8 through the suction hose 20. The suction holes 22 evenly distributed through the bottom surface of the suction cavity convert the negative pressure into a suction force on the tool, achieving efficient suction of the tool. This structural design ensures that the suction force is evenly distributed on the tool surface, avoiding tool detachment or damage due to uneven suction force, and improving the reliability of the unloading process.

[0034] A top plate 23 is fixed to one side of the upper end of the upright 5. A cylinder C24 is located at the bottom of the top plate 23, providing a mounting base for the cylinder C24 and ensuring its stability during operation. The cylinder C24 precisely controls the up-and-down movement of the pneumatic plate 6, enabling it to accurately impact and drill the tool and perform downward clamping positioning operations, ensuring the accuracy and stability of the drilling process. One end of the cylinder C24 is fixed to the upper surface of the pneumatic plate 6. The lower surface of the impact drilling plate 7 at the bottom of the pneumatic plate 6 is equipped with an impact drilling head 25 corresponding to the through hole 12, directly acting on the tool for impact drilling. Its design shape and size correspond to the through hole 12, ensuring the accuracy of the drilling position and the drilling quality. The impact drilling head 25 is made of high-strength material and can withstand significant impact forces.

[0035] Specifically, during use, the tool is placed in the tool clamping plate 3, and cylinder A13 is activated. Cylinder A13 pushes the moving clamping plate 14 towards the tool, achieving clamping and positioning of the tool. Because the guide groove 15 at the bottom of the moving clamping plate 14 slides with the guide rod, it ensures that the moving clamping plate 14 can move precisely in a straight line, avoiding tool tilting or jamming and ensuring accurate positioning. Simultaneously, the three through holes 12 in the tool positioning cavity of the tool clamping plate 3 correspond perpendicularly to the receiving frame 4, laying the foundation for subsequent waste material adsorption. The servo motor 9 at the center of the end of the stabilizing seat 1 is activated, and its shaft drives the drilling turntable 2 to rotate, sequentially rotating the tool clamping plate 3 containing the tool to the designated drilling position. At this time, the upper side of the upright 5 is driven by cylinder C24 to move the pneumatic plate 6 downwards. The impact drilling plate 7, with the same shape as the inner cavity of the tool clamping plate 3, moves downwards accordingly. The impact drilling head 25 on the lower surface of the impact drilling plate 7 corresponds to the through hole 12, performing impact drilling on the tool. During the drilling process, the pneumatic plate 6 also serves to press and position the cutting tool, ensuring the stability of the drilling operation.

[0036] Waste generated during the drilling process falls vertically into the collection frame 4 through the through hole 12 of the cutter clamp 3. The suction device 10 is activated, generating negative pressure. The suction pipe transports the waste in the collection frame 4 to the collection box 11 through the pipeline, achieving the adsorption and collection of the waste generated during the drilling process, maintaining the cleanliness of the working area, and preventing the waste from interfering with subsequent processes. After drilling is completed, the rotating motor 17 in the concave cavity at the end of the stabilizing rod 26 rotates, driving the rotating rod 18 to rotate, causing the pneumatic suction plate 8 connected to the cylinder B19 on the lower end face of the rotating rod 18 to rotate above the cutter. Then, the cylinder B19 is activated, pushing the pneumatic suction plate 8 down to approach the cutter. The suction pump 21 is turned on, and the suction hose 20 creates negative pressure in the suction cavity of the pneumatic suction plate 8. The suction holes 22 evenly distributed on the bottom surface of the suction cavity adsorb the cutter. Next, cylinder B19 drives the pneumatic suction plate 8 to rise, and the rotating motor 17 rotates again, rotating the pneumatic suction plate 8 with the blade attached to it to the unloading position to complete the unloading action. The entire unloading process is carried out through non-contact air pressure adsorption, avoiding damage to the blade surface.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
