Description

Technical Field

[0001] This utility model relates to the technical field of machining equipment, and in particular to a drilling device for machining parts. Background Technology

[0002] Currently, in the process of manufacturing parts such as gears, the drilling process is as follows: the worker loads the workpiece onto the fixture of the drilling device and fixes it, then manually operates the drill bit of the drilling device to drill the workpiece, and finally the worker unlocks the fixture and unloads the workpiece. This processing method has a low degree of automation, is cumbersome to operate, and has a high labor intensity for workers, making it difficult to apply to automated production lines for mass production. Utility Model Content

[0003] The purpose of this utility model is to provide a drilling device for parts processing, which has the advantages of simple structure, reasonable design, high degree of automation, reduced labor intensity of workers, and suitability for mass production on automated production lines.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a drilling device for parts processing, including a base, a feeding turntable, a drive mechanism, a clamping mechanism, a drilling mechanism and a control module;

[0005] An installation surface is formed on the base, and a positioning protrusion is formed on the installation surface. The positioning protrusion is a cylindrical structure.

[0006] The drilling mechanism is mounted on the base and above the mounting plane. The lower side of the drilling mechanism is equipped with a drill bit that can move up and down. The drill bit of the drilling mechanism can perform drilling operations by moving up and down and rotating itself.

[0007] The feeding turntable has a disc structure with a fitting hole at its center. The feeding turntable is rotatably fitted onto the positioning protrusion through the fitting hole. The rotation axis of the feeding turntable is set along the central axis of the positioning protrusion. Several material placement areas are set on the top surface of the feeding turntable, and these material placement areas are arranged around the rotation axis of the feeding turntable. One of the material placement areas is located directly below the drilling mechanism. The position of this material placement area is called the working station. The feeding turntable rotates so that the material placement areas enter the working station in sequence. The drive mechanism is mounted on the base and is used to drive the feeding turntable to rotate.

[0008] The clamping mechanism includes a first clamping component and a second clamping component. The first clamping component and the second clamping component are arranged separately along the radial direction of the feeding turntable. The first clamping component is installed on the mounting plane of the base and is located beside the feeding turntable. The second clamping component is installed on the positioning protrusion. The height of the first clamping component and the second clamping component is between the feeding turntable and the drilling mechanism. The first clamping component and the second clamping component are located on both sides of the working position. The first clamping component and the second clamping component are both provided with a retractable clamping end. The clamping ends of the first clamping component and the second clamping component work together to clamp and fix the workpiece in the working position through the retractable action.

[0009] The control module is electrically connected to the drive mechanism, the first clamping assembly, the second clamping assembly, and the drilling mechanism. The control module is used to control the operation of the drive mechanism, the clamping mechanism, and the drilling mechanism.

[0010] The working principle of this utility model is as follows:

[0011] This drilling device is used in conjunction with external feeding and external discharging robotic arms. The external feeding and discharging robotic arms are positioned near one of the material placement areas, excluding the designated workstation area. The location of the material placement area near the external feeding robotic arm is called the feeding station, and the location of the material placement area near the external discharging robotic arm is called the discharging station. During operation, the external feeding robotic arm transports the workpiece and places it on the material placement area at the feeding station. The feeding turntable rotates in a stepping motion, driving each material placement... The feeding area moves in a circular motion, allowing the workpiece originally at the feeding station to enter the working station. The clamping ends of the first clamping assembly work together through telescopic movements to clamp and fix the workpiece at the working station. The drill bit of the drilling mechanism moves up and down and rotates to perform drilling, thus drilling the workpiece. The feeding turntable continues to rotate in a stepping manner, driving each feeding area in a circular motion, transporting the workpiece from the working station to the unloading station. An external unloading robotic arm then unloads the workpiece from the unloading station. This design gives the drilling device a high degree of automation, reduces the labor intensity of workers, and makes it suitable for mass production on automated production lines. Furthermore, by separating the first clamping assembly and the second clamping assembly along the radial direction of the feeding turntable, a clearance space is formed between the first clamping assembly and the second clamping assembly when the clamping ends of the first clamping assembly and the second clamping assembly are in the contracted state. This allows the workpiece driven by the feeding turntable to enter or leave the working position through the clearance space without being blocked. This design makes the structure of this drilling device more compact, thereby reducing the space occupied and making it more conducive to the layout of automated production lines.

[0012] Furthermore, in the aforementioned drilling device for parts processing, at least one locking groove is formed on the mounting plane; a group of locking holes is formed on the feeding turntable, with each group of locking holes corresponding to a material placement area. The group of locking holes includes at least one locking hole, and the number of locking holes matches the number of locking grooves. When a material placement area is driven into the working position by the feeding turntable, the openings of the locking holes in the group of locking holes corresponding to the material placement area are aligned with the openings of the locking grooves. A locking mechanism is also included, mounted on a base. The locking mechanism has at least one locking post, which can move up and down. Each locking post corresponds to a locking groove. The locking post, through its up-and-down movement, allows its lower end to pass through the corresponding locking hole and lock into the locking groove to lock the feeding turntable. The locking mechanism is electrically connected to the control module.

[0013] Furthermore, in the aforementioned drilling device for machining parts, a material placement boss is formed at the position of each material placement area of ​​the feeding turntable, and a material placement groove is formed at the center of the top surface of the material placement boss. The lower part of the side wall of the material placement groove is connected to the bottom of the groove through a pair of centering guide surfaces. The centering guide surfaces are annular curved surfaces that gradually move away from the central axis of the material placement groove from bottom to top. A clearance hole is formed at the center of the bottom of the material placement groove.

[0014] Furthermore, in the drilling device for machining parts as described above, the clamping ends of the first clamping assembly and the second clamping assembly are arc-shaped clamping plates facing the direction of the working station.

[0015] Furthermore, in the drilling device for parts processing described above, a first mounting ring groove and a second mounting ring groove are formed on the mounting plane. Both the first and second mounting ring grooves are annular structures surrounding the central axis of the positioning protrusion. A first annular protrusion and a second annular protrusion are formed on the bottom surface of the feeding turntable. Both the first and second annular protrusions are annular structures surrounding the axis of the feeding turntable. Several material placement areas are located between the first and second annular protrusions. The first annular protrusion is slidably embedded in the first mounting ring groove, and the second annular protrusion is slidably embedded in the second mounting ring groove, so that an installation gap is formed between the bottom surface of the feeding turntable and the mounting plane.

[0016] Furthermore, in the aforementioned drilling device for parts processing, the outer periphery of the feeding turntable has a toothed structure; the driving mechanism includes a driving motor and a driving gear, the driving motor is mounted on a base, the driving gear is coaxially fixed on the output shaft of the driving motor, the driving gear meshes with the toothed structure of the feeding turntable, and the driving motor is electrically connected to the control module.

[0017] Furthermore, in the drilling device for parts processing described above, a Hall sensor is provided on the positioning protrusion, and the Hall sensor is electrically connected to the control module; several magnets are provided on the top surface of the feeding turntable, with each magnet corresponding to a material placement area. When a material placement area is driven into the working position by the feeding turntable, the magnet corresponding to that material placement area is directly opposite the Hall sensor.

[0018] Further, as described above, in a drilling device for machining parts, a supporting boss is formed at the center of the top surface of the positioning protrusion; it also includes a flange and a mounting plate, a center hole is formed at the center of the flange, a positioning ring is formed on the bottom surface of the flange, the flange is fitted onto the supporting boss through the center hole, and the flange is fitted onto the positioning protrusion through the positioning ring, the flange and the positioning protrusion are connected and fixed, and the second clamping assembly is mounted and fixed on the flange; a first straight baffle, a second straight baffle and a third straight baffle are formed on the mounting plane, the first straight baffle is positioned in the second clamping... The pressure assembly is positioned opposite the working station and directly opposite it. One end of the first straight baffle is connected to one end of the second straight baffle, and the other end of the first straight baffle is connected to the third straight baffle. The second and third straight baffles are arranged parallel to each other and are located on both sides of the second clamping assembly. The top surfaces of the first, second, and third straight baffles and the top surface of the support boss are flush with each other. The mounting plate is positioned above the mounting plane and is fixed to the top surfaces of the first, second, and third straight baffles and the support boss. The drilling mechanism is mounted and fixed on the mounting plate.

[0019] Furthermore, in the aforementioned drilling device for parts processing, the drilling mechanism is further provided with a cooling nozzle, which is positioned towards the working station and sprays coolant onto the workpiece at the working station. An installation space is formed on the base, located below the installation plane, and a collection chamber is placed within the installation space.

Detailed Implementation

[0032] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] like Figures 1 to 8 A drilling device for machining parts, as an example, includes a base 1, a feeding turntable 2, a drive mechanism 3, a clamping mechanism 4, a drilling mechanism 5, and a control module (the control module is not shown in the drawings).

[0034] A mounting surface 11 is formed on the base 1, and a positioning protrusion 12 is formed on the mounting surface 11. The positioning protrusion 12 is a cylindrical structure.

[0035] The drilling mechanism 5 is mounted on the base 1 and above the mounting plane 11. The lower side of the drilling mechanism 5 is provided with a drill bit 51 that can move up and down. The drill bit 51 of the drilling mechanism 5 can perform drilling operations by moving up and down and rotating itself.

[0036] The feeding turntable 2 has a disc structure. A fitting hole 21 is formed at the center of the feeding turntable 2. The feeding turntable 2 is rotatably fitted onto the positioning protrusion 12 through the fitting hole 21. The rotation axis of the feeding turntable 2 is set along the central axis of the positioning protrusion 12. Four material placement areas are set on the top surface of the feeding turntable 2. The four material placement areas are arranged around the rotation axis of the feeding turntable 2. One of the material placement areas is located directly below the drilling mechanism 5. The position of this material placement area is called the working station. The feeding turntable 2 rotates so that the four material placement areas enter the working station in sequence. The drive mechanism 3 is installed on the base 1. The drive mechanism 3 is used to drive the feeding turntable 2 to rotate.

[0037] The clamping mechanism 4 includes a first clamping component 41 and a second clamping component 42. The first clamping component 41 and the second clamping component 42 are arranged separately along the radial direction of the feeding turntable 2. The first clamping component 41 is installed on the mounting plane 11 of the base 1 and is located on the side of the feeding turntable 2. The second clamping component 42 is installed on the positioning protrusion 12. The height positions of the first clamping component 41 and the second clamping component 42 are both between the feeding turntable 2 and the drilling mechanism 5. The first clamping component 41 and the second clamping component 42 are located on both sides of the working position. The first clamping component 41 and the second clamping component 42 are both provided with a retractable clamping end. The clamping ends of the first clamping component 41 and the second clamping component 42 cooperate to clamp and fix the workpiece 30 in the working position through the retractable action.

[0038] The control module is electrically connected to the drive mechanism 3, the first clamping assembly 41, the second clamping assembly 42, and the drilling mechanism 5. The control module is used to control the operation of the drive mechanism 3, the clamping mechanism 4, and the drilling mechanism 5.

[0039] By designing the first clamping assembly 41 and the second clamping assembly 42 separately arranged along the radial direction of the feeding turntable 2, a clearance space is formed between the first clamping assembly 41 and the second clamping assembly 42 when the clamping ends of the first clamping assembly 41 and the second clamping assembly 42 are in the contracted state. This allows the workpiece 30 driven by the feeding turntable 2 to enter or leave the working position through the clearance space without being blocked. This design makes the structure of this drilling device more compact, thereby reducing the space occupied and making it more conducive to the layout of automated production lines.

[0040] like Figure 2 , Figure 5 and Figure 8As shown, two locking slots 15 are formed on the mounting plane 11; eight locking holes 23 are formed on the feeding turntable 2, with each pair of locking holes 23 forming a group corresponding to a material placement area. When a material placement area is driven into the working position by the feeding turntable 2, the openings of the two locking holes 23 corresponding to the material placement area are respectively aligned with the openings of the two locking slots 15. A locking mechanism is also included, which includes two locking cylinders 6. Both locking cylinders 6 are mounted on the base 1. Each locking cylinder 6 is provided with a locking pin 61 that can move up and down. One locking cylinder 6 corresponds to one locking slot 15. The locking pin 61 of the locking cylinder 6 moves up and down so that its lower end passes through the corresponding locking hole 23 and locks into the locking slot 15 to lock the feeding turntable 2. The locking mechanism is electrically connected to the control module. When in use, after the feeding turntable 2 rotates and transports the workpiece 30 to the working position, the locking mechanism locks the feeding turntable 2 to prevent it from rotating during the operation of the clamping mechanism 4 and the drilling mechanism 5, which would affect the processing effect and improve the processing accuracy.

[0041] like Figure 6 As shown, each material placement area of ​​the feeding turntable 2 has a material placement boss 22, and a material placement groove 221 is formed at the center of the top surface of the material placement boss 22. The lower part of the side wall of the material placement groove 221 is connected to the bottom of the groove by a pair of centering guide surfaces 222. The centering guide surfaces 222 are annular curved surfaces that gradually move away from the central axis of the material placement groove 221 from bottom to top. A clearance hole 223 is formed at the center of the bottom of the material placement groove 221. The clearance hole 223 is used to provide movement space for the drill bit 51 of the drilling mechanism 5. In this embodiment, the workpiece 30 being processed is a cylindrical structure with cylindrical bosses 301 formed on both the top and bottom surfaces. The cylindrical bosses 301 on the lower side of the workpiece 30 are placed in the material placement groove 221 to prevent the workpiece 30 from leaving the material placement area during the rotation of the feeding turntable 2. Since the opening of the material placement groove 221 is larger than the diameter of the cylindrical bosses 301, the accuracy requirements for feeding and discharging the workpiece 30 can be reduced, which is beneficial for the application of this drilling device in an automated production line. When the cylindrical bosses 301 of the workpiece 30 are offset from the material placement groove 221, the cylindrical bosses 301 slide toward the center of the material placement groove 221 under the action of the guide surface to achieve automatic centering adjustment of the workpiece 30.

[0042] like Figure 2 As shown, the first clamping assembly 41 and the second clamping assembly 42 are electrically driven, and the clamping ends of the first clamping assembly 41 and the second clamping assembly 42 are arc-shaped clamping plates 43 facing the direction of the working station. With this design, during the process of clamping the workpiece 30 at the working station, the first clamping assembly 41 and the second clamping assembly 42 can adjust the centering of the workpiece 30, further improving the machining accuracy of this drilling device.

[0043] like Figure 4 , Figure 7 and Figure 8 As shown, a first mounting ring groove 13 and a second mounting ring groove 14 are formed on the mounting plane 11. Both the first mounting ring groove 13 and the second mounting ring groove 14 are annular structures surrounding the central axis of the positioning protrusion 12. The first mounting ring groove 13 is located inside the second mounting ring groove 14. A first annular protrusion 24 and a second annular protrusion 25 are formed on the bottom surface of the feeding turntable 2. Both the first annular protrusion 24 and the second annular protrusion 25 are annular structures surrounding the axis of the feeding turntable 2. The four material placement areas are all located between the first annular protrusion 24 and the second annular protrusion 25. The first annular protrusion 24 is slidably embedded in the first mounting ring groove 13, and the second annular protrusion 25 is slidably embedded in the second mounting ring groove 14, so that an installation gap is formed between the bottom surface of the feeding turntable 2 and the mounting plane 11. This design achieves several advantages. First, the feeding turntable 2 is supported on the base 1, making it more stable. When the drilling mechanism 5 performs drilling, the feeding turntable 2 provides better support for the workpiece 30, thereby improving machining accuracy. Second, since all four material placement areas are located between the first annular protrusion 24 and the second annular protrusion 25, the force structure of the feeding turntable 2 is more reasonable and stable when the drilling mechanism 5 performs drilling, further improving machining accuracy. Third, the first annular protrusion 24 and the second annular protrusion 25 create an installation gap between the feeding turntable 2 and the mounting plane 11, reducing the contact area between the feeding turntable 2 and the mounting plane 11, making the rotation of the feeding turntable 2 smoother.

[0044] like Figure 2 and Figure 7As shown, the outer periphery of the feeding turntable 2 has a toothed structure 26; the driving mechanism 3 includes a driving motor 31 and a driving gear 32. The driving motor 31 is mounted on the base 1, and the driving gear 32 is coaxially fixed on the output shaft of the driving motor 31. The driving gear 32 meshes with the toothed structure 26 of the feeding turntable 2, and the driving motor 31 is electrically connected to the control module. A Hall sensor 7 is provided on the positioning protrusion 12, and the Hall sensor 7 is electrically connected to the control module; four magnets 8 are provided on the top surface of the feeding turntable 2, each magnet 8 corresponding to a material placement area. When a material placement area is driven into the working position by the feeding turntable 2, the magnet 8 corresponding to that material placement area is directly opposite the Hall sensor 7. When the feeding turntable 2 rotates to feed material, the control module controls the drive motor 31 to work, causing the drive gear 32 to rotate and drive the feeding turntable 2 to rotate. When a material placement area is driven into the working position by the feeding turntable 2, the magnet 8 corresponding to the material placement area is aligned with the Hall sensor 7 and triggers the Hall sensor 7. The Hall sensor 7 sends a trigger signal to the control module, and the control module controls the drive motor 31 to stop working. Through this design, the rotation feeding action of the feeding turntable 2 is more precise, thereby improving the processing accuracy of this drilling device.

[0045] like Figure 2 , Figure 4 and Figure 8As shown, a supporting boss 121 is formed at the center of the top surface of the positioning protrusion 12; a flange 9 and a mounting plate 10 are also present. A center hole is formed at the center of the flange 9, and a positioning protrusion 91 is formed on the bottom surface of the flange 9. The flange 9 is fitted onto the supporting boss 121 through the center hole, and onto the positioning protrusion 12 through the positioning protrusion 91. The flange 9 is connected and fixed to the top surface of the positioning protrusion 12 by bolts. The second clamping assembly 42 and the Hall sensor 7 are mounted and fixed on the flange 9. A first straight baffle 161, a second straight baffle 162, and a third straight baffle 163 are formed on the mounting plane 11. The first straight baffle 161 is located on the side of the second clamping assembly 42 that faces away from the working position and is directly opposite the working position. One end of the first straight baffle 161 is connected to one end of the second straight baffle 162, and the other end of the first straight baffle 161 is connected to the third straight baffle 163. Baffle 162 and third straight baffle 163 are arranged in parallel and located on both sides of the second clamping assembly 42. Corner members 165 are installed and fixed between the first straight baffle 161 and the second straight baffle 162, and between the first straight baffle 161 and the third straight baffle 163. A mounting surface is formed on the corner member 165. The mounting surface of the corner member 165, the top surface of the first straight baffle 161, the top surface of the second straight baffle 162, the top surface of the third straight baffle 163, and the top of the support boss 121 are all included in this arrangement. The surfaces are flush with each other; the mounting plate 10 is located above the mounting plane 11, and is placed on the top surfaces of the first straight baffle 161, the second straight baffle 162, the third straight baffle 163, the support boss 121, and the two corner pieces 165. The mounting plate 10 is connected and fixed to the top surface of the support boss 121 and the mounting surfaces of the two corner pieces 165 by bolts. The drilling mechanism 5 and the locking mechanism are both installed and fixed on the mounting plate 10. By installing the second clamping assembly 42 and the Hall sensor 7 on the flange 9, it is not necessary to disassemble the second clamping assembly 42 and the Hall sensor 7 when the feeding turntable 2 needs to be maintained or replaced, making the operation more convenient. By placing the mounting plate 10 on the top surfaces of the first straight baffle 161, the second straight baffle 162, the third straight baffle 163, the support boss 121, and the two corner members 165, the structure of the mounting plate 10 can be made more stable. This avoids the drilling mechanism 5 and the locking mechanism being placed on a structure that is suspended on one side, making the drilling mechanism 5 and the locking mechanism more stable during operation and achieving better working results.

[0046] like Figure 4 , Figure 5 and Figure 8As shown, the drilling mechanism 5 is also equipped with a cooling nozzle 52, which is oriented towards the working position and is used to spray coolant onto the workpiece 30 at the working position. An installation space 17 is formed on the base 1, located below the installation plane 11, and a collection chamber 20 is placed in the installation space 17. An arc-shaped baffle 164 is formed on the installation plane 11, located outside the feeding turntable 2, with the center of the arc of the baffle 164 on the central axis of the positioning protrusion 12. One end of the arc-shaped baffle 164 is connected to the other end of the second straight baffle 162, and the other end of the arc-shaped baffle 164 is connected to the other end of the third straight baffle 163, so that the arc-shaped baffle 164, the first straight baffle 161, the second straight baffle 162 and the third straight baffle 163 are combined to form a liquid-blocking enclosure 16; a first liquid-blocking protrusion 131 is formed on the mounting plane 11 along the inner ring edge of the groove of the first mounting ring groove 13, and a second liquid-blocking protrusion 132 is formed along the outer ring edge of the groove of the first mounting ring groove 13, and along the inner ring edge of the groove of the second mounting ring groove 14. A third liquid-blocking protrusion 141 is formed on the edge of the ring, and a fourth liquid-blocking protrusion 142 is formed along the outer edge of the groove of the second mounting ring 14. A first drain port 111, a second drain port 112, and a waste discharge port 113 communicating with the mounting space 17 are formed on the mounting plane 11. The first drain port 111 is located inside the first liquid-blocking protrusion 131, the second drain port 112 is located between the fourth liquid-blocking protrusion 142 and the liquid-blocking enclosure 16, and the waste discharge port 113 is located between the second liquid-blocking protrusion 132 and the third liquid-blocking protrusion 141. The waste discharge port 113 is connected to the liquid-blocking enclosure 17. The clearance hole 223 in the material placement area of ​​the working station is directly opposite; a third drain port 133 communicating with the installation space 17 is formed on the bottom of the first mounting ring groove 13, a fourth drain port 143 communicating with the installation space 17 is formed on the bottom of the second mounting ring groove 14, and a fifth drain port 151 is formed on the bottom of each locking groove 15; the lower openings of the first drain port 111, the second drain port 112, the third drain port 133, the fourth drain port 143, the fifth drain port 151 and the waste discharge port 113 are all directly opposite the opening of the collection bin 20.By forming the liquid-blocking baffle 16 structure, the coolant overflows from the mounting plane 11 during operation and does not affect the surrounding environment. Since the bottom of the first mounting ring groove 13 and the bottom of the second mounting ring groove 14 are in close contact with the first annular protrusion 24 and the second annular protrusion 25 respectively, the coolant entering the first mounting ring groove 13 and the second mounting ring groove 14 is difficult to discharge quickly. By forming the first liquid-blocking protrusion 131, the second liquid-blocking protrusion 132, the third liquid-blocking protrusion 141 and the fourth liquid-blocking protrusion 142, the amount of coolant entering the first mounting ring groove 13 and the second mounting ring groove 14 can be reduced, and the discharge of coolant can be accelerated. The waste discharge port 113 is used to discharge the coolant that enters the second liquid-blocking protrusion 132 and the third liquid-blocking protrusion 141 from the clearance hole 223 of the feeding turntable 2. The waste generated when the drilling mechanism 5 is working passes through the clearance hole 223 and the waste discharge port 113 in the working position and enters the collection bin 20 for collection and storage.

[0047] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, an observation port 1611 is formed on the first straight baffle 161. This design allows workers to easily observe the working conditions at their workstations.

[0048] The working principle of this embodiment is as follows:

[0049] This drilling device is used in conjunction with an external feeding robotic arm and an external discharging robotic arm. The external feeding robotic arm and the external discharging robotic arm are respectively set near one of the material placement areas other than the material placement area in the working position. The position of the material placement area near the external feeding robotic arm is called the feeding position, and the position of the material placement area near the external discharging robotic arm is called the discharging position.

[0050] During operation, the control module controls the drive motor 31 to work, and the feeding turntable 2 rotates, causing each material placement area to move in a circular motion. When the next material placement area enters the working position, the Hall sensor 7 is triggered, the control module controls the drive motor 31 to stop working, and the control module controls the locking mechanism to work. The lower ends of the locking pins 61 of the two locking cylinders 6 pass through the locking holes 23 and lock into the corresponding locking slots 15 to lock the feeding turntable 2. At this time, the external feeding robot arm transports the workpiece 30 and places it on the material placement area at the feeding position, and the external discharging robot arm transports the workpiece 30 at the discharging position. The control module controls the clamping mechanism 4 to work. The first clamping assembly 41 and its respective clamping ends work together through telescopic movements to clamp and fix the workpiece 30 in the working position. The control module controls the drilling mechanism 5 to work, with the drill bit 51 of the drilling mechanism 5 moving up and down and rotating to perform drilling. At the same time, the cooling nozzle 52 of the drilling mechanism 5 sprays coolant towards the workpiece 30 to achieve drilling. The control module controls the drilling mechanism 5 to stop working and controls the drilling mechanism 5, clamping mechanism 4, and locking mechanism to reset, thereby releasing the lock on the feeding turntable 2 and the workpiece 30. The control module controls the drive motor 31 to work, and the rotation of the feeding turntable 2 drives each material placement area to perform circular motion to repeat the above process. Through this design, the drilling device has a high degree of automation, reduces the labor intensity of workers, and is suitable for mass production on automated production lines.
