Description

Technical Field

[0001] This invention relates to a drilling device, specifically a drilling device and drilling process for making holes along the circumference of a heating plate. Background Technology

[0002] A drilling device is a mechanical device used to create holes on or inside an object. Depending on the application, drilling devices can be used to drill holes in various materials such as metal, wood, concrete, and plastic. The working principle of a drilling device is usually to rotate the drill bit and apply a certain pressure to penetrate the object and form the required hole. A heating plate is a device commonly used for heating and heat exchange, usually in industrial, laboratory, and kitchen fields. It transfers heat to the object being heated through conduction or radiation. When processing a heating plate, a drilling device is needed to drill holes in it to meet the requirements for subsequent installation and use between the heating plate and other components.

[0003] Current drilling equipment typically places the heating plate on a rotary drilling machine when machining holes along the circumference of the heating plate. The rotation of the rotary table moves the heating plate to the drilling position for precise machining. In order to ensure that the heating plate remains firmly positioned during drilling and to prevent drilling accuracy problems caused by displacement, pneumatic devices such as cylinders are usually used to clamp and fix the heating plate. In this way, the cylinder can provide sufficient pressure to stabilize the heating plate in the required position, thereby ensuring the accuracy and efficiency of the drilling process.

[0004] However, when multiple heating plate placement stations are set up on the turntable, each heating plate usually needs to be equipped with an independent cylinder to ensure that the heating plate at each station can be stably fixed. Although this method can achieve independent clamping at each station, it also leads to a significant increase in equipment procurement costs. In addition, the parallel use of multiple cylinders will increase the complexity of the equipment and increase the probability of failure. Once any one of the cylinders fails, the entire drilling device may not be able to operate normally, thus forcing the equipment to be shut down for maintenance. This not only increases the risk of production downtime, but also has a significant impact on the efficient use of the overall equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a drilling device and drilling process for drilling holes along the circumference of a heating plate, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A drilling device for taking holes along the circumference of a heating plate includes a drilling worktable, two drilling machines symmetrically installed on the drilling worktable, and a loading and unloading robotic arm installed on the drilling worktable. A self-clamping feeding structure is installed on the drilling worktable, and a linkage mechanism is provided on one side of the self-clamping feeding structure. The bottom of the linkage mechanism is connected to the drilling worktable, and the top of the linkage mechanism is connected to one of the drilling machines.

[0008] The self-clamping feeding structure includes an installation mechanism connected to the drilling workbench, a feeding tray mechanism installed on the installation mechanism, a plurality of clamping mechanisms provided on the feeding tray mechanism, and an abutment mechanism provided on the drilling workbench and connected to the clamping mechanisms.

[0009] When the drilling machine moves up and down to drill, it drives the linkage mechanism to move. When the linkage mechanism moves, it drives the mounting mechanism and the feeding tray mechanism to rotate on the drilling worktable. When the feeding tray mechanism moves, the clamping mechanism on the feeding tray mechanism is rotatably connected to the abutting mechanism, thereby controlling the clamping or releasing action of the clamping mechanism.

[0010] A drilling device for taking holes along the circumference on a heating plate as described above: the mounting mechanism includes a bearing fixedly connected to the drilling worktable on the outer ring and a rotating shaft fixed to the inner ring of the bearing, the rotating shaft being rotatably connected to the drilling worktable through the bearing.

[0012] A gear ring is fixedly connected to the outer edge of the turntable, and multiple sliding grooves are arranged in a ring array on the turntable at each support base location.

[0013] A drilling device for taking holes along the circumference on a heating plate as described above: the linkage mechanism includes a gear meshing with the gear ring, a plug-in pin connected to the gear, and a linkage rod connected to the gear;

[0014] The top of the linkage rod is fixedly connected to a mounting plate, which is installed on one of the drilling machines. The outer wall of the linkage rod is provided with a spiral groove.

[0015] A ratchet is fixedly connected to the top of the plug post. The ratchet is connected to the gear. A semi-circular protrusion is fixedly connected to the inner wall of the ratchet. The semi-circular protrusion is slidably connected to the spiral groove.

[0016] A drilling device for taking holes along the circumference on a heating plate as described above: the clamping mechanism includes a sliding block slidably connected in the sliding groove, a collar connected to the sliding block, a guide post connected to the collar, and an adjustment component connected to the guide post;

[0017] A clamping plate is fixedly connected to one side of the top of the sliding block, and the bottom of the clamping plate slides against the surface of the turntable. A boss is symmetrically fixedly connected to the bottom of the sliding block, and a rolling roller is rotatably connected to the boss. The rolling roller abuts against the bottom surface of the turntable.

[0018] A connecting rod is provided between the sliding block and the collar. One end of the connecting rod is rotatably connected to the bottom end of the sliding block, and the other end is rotatably connected to a rotating seat fixedly connected to the outer wall of the collar.

[0019] A drilling device for taking holes along the circumference of a heating plate as described above: a central block is fixedly connected to the center of the collar, a gear column is provided at the bottom of the central block, and the top of the gear column is rotatably connected to the central block;

[0020] The collar is slidably sleeved with the guide post. The top of the guide post is fixedly connected to the turntable. The guide post has a lifting groove that is slidably connected to the center block. The guide post also has a notch. A screw is slidably connected in the lifting groove. The screw is threadedly connected to a threaded hole at the bottom of the gear post. An abutment rod is fixedly connected to the bottom of the screw. The abutment rod is slidably connected in the lifting groove. Both ends of the abutment rod extend out of the outer wall of the guide post.

[0021] The adjustment assembly includes an adjustment ring rotatably connected to the notched portion and an inner ring gear disposed on the inner wall of the adjustment ring, the inner ring gear meshing with the gear post.

[0022] A drilling device for taking holes along the circumference on a heating plate as described above: the abutting mechanism includes a first support ring fixedly connected to the drilling worktable and a second support ring fixedly connected to the outer ring of the first support ring on the drilling worktable;

[0023] The first and second support rings are provided with a first adjustment groove and a second adjustment groove on their opposite surfaces. The first and second support rings on both sides of the second adjustment groove are provided with a third adjustment groove. The height of the first adjustment groove is lower than that of the second adjustment groove. The third adjustment groove is inclined to connect the first adjustment groove and the second adjustment groove.

[0024] The spacing between the first support ring and the second support ring is the same as the diameter of the guide post.

[0025] A drilling device for taking holes along the circumference of a heating plate as described above: the two ends of the abutment rod are respectively slidably connected to the first adjustment groove, the second adjustment groove and the third adjustment groove opened on the first support ring and the second support ring.

[0026] The drilling process using a drilling apparatus described above for taking holes circumferentially on a heating plate includes the following steps:

[0027] Step 1: The heating plate is placed on the turntable by the loading and unloading robotic arm. The clamping plate located at the loading and unloading robotic arm is in an expanded state at this time.

[0028] Step 2: When the drilling machine is lowered to drill holes in the heating plates on the turntable and then raised, it can drive the gears to rotate, causing the turntable to rotate, so that the multiple heating plates placed on the turntable can supply power to the drilling station.

[0029] Step 3: When the abutment rod moves from the second adjustment groove to the first adjustment groove, it can drive the collar to descend on the guide post. At this time, the multiple connecting rods connected to the collar can move together to make the multiple clamping plates gather inward.

[0030] Step 4: The converging clamping plates can clamp and fix the heating plate placed on the turntable, so that the heating plate is stably placed on the turntable for drilling.

[0031] Step 5: The processed heating plate moves to the loading / unloading robotic arm under the rotation of the turntable. At this time, the clamping plate expands outward and loses its grip on the heating plate. The loading / unloading robotic arm can then remove the drilled heating plate and place an un-drilled heating plate in it for subsequent drilling operations.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] Through the rational design of the self-clamping feeding structure and its connection relationship, the heating plate can be automatically fed and clamped. The self-clamping feeding structure is connected to the linkage mechanism between the worktable and the drilling machine. During the lifting and lowering movement of the drilling machine, it can drive the feeding structure to perform corresponding actions, ensuring that the heating plate can be accurately moved to the designated drilling position one by one when the drilling machine is working.

[0034] When the lifting device of the drilling machine drills holes in the heating plate, the linkage mechanism, in close cooperation with the self-clamping feeding structure, enables the heating plate to move and position automatically. Through this mechanism, each heating plate can enter the drilling station at a precise time and be stably clamped and fixed during the drilling process, avoiding processing errors caused by loosening or displacement of the plate. The design of the linkage mechanism is also key to ensuring the efficient operation of the entire system. The linkage mechanism needs to be synchronized with the lifting action of the drilling machine to ensure that each heating plate can smoothly and stably enter the next drilling station during the lifting process of the drilling machine. The combination of the self-clamping feeding structure and the linkage mechanism enables the heating plate to automatically enter the next drilling station during the processing, which greatly improves production efficiency and enhances the automation level and reliability of the entire production line.

[0035] Specifically, through the connection between the linkage mechanism and the drilling machine and the feeding plate mechanism, the feeding plate mechanism can be driven to rotate synchronously when the drilling machine is raised and lowered, so that the heating plates move to the drilling station one by one. Through the clamping mechanism set on the feeding plate mechanism and connected to the abutment mechanism, the heating plates can be firmly clamped, reducing the use of independent clamping drive sources and improving the linkage effect of the overall device.

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0051] Please see Figures 1-5 In this embodiment of the invention, a drilling device for taking holes along the circumference of a heating plate includes a drilling worktable 1, two drilling machines 2 symmetrically installed on the drilling worktable 1, and a loading and unloading robotic arm 3 installed on the drilling worktable 1. A self-clamping feeding structure is installed on the drilling worktable 1, and a linkage mechanism is provided on one side of the self-clamping feeding structure. The bottom of the linkage mechanism is connected to the drilling worktable 1, and the top of the linkage mechanism is connected to one of the drilling machines 2.

[0052] The self-clamping feeding structure includes an installation mechanism connected to the drilling workbench 1, a feeding tray mechanism installed on the installation mechanism, a plurality of clamping mechanisms provided on the feeding tray mechanism, and an abutment mechanism provided on the drilling workbench 1 and connected to the clamping mechanisms.

[0053] When the drilling machine 2 moves up and down to drill, it drives the linkage mechanism to move. When the linkage mechanism moves, it drives the mounting mechanism and the feeding tray mechanism to rotate on the drilling worktable 1. When the feeding tray mechanism moves, the clamping mechanism on the feeding tray mechanism is rotatably connected to the abutting mechanism, thereby controlling the clamping or releasing action of the clamping mechanism.

[0054] In this embodiment, the drilling machine 2 needs to be raised and lowered during drilling to drill the heating plate placed on the feeding tray mechanism. When the drilling machine 2 is raised, it drives the linkage mechanism to move, which in turn drives the feeding tray mechanism to rotate. The feeding tray mechanism is mounted on the mounting mechanism, which rotates on the drilling worktable 1. Therefore, the feeding tray mechanism can rotate on the drilling worktable 1. When the drilling machine 2 is raised to its position, the workstation on the feeding tray mechanism rotates exactly one workstation distance, allowing the previous workstation to move to the next workstation, thus realizing the drilling of multiple heating plates. The feeding trays are fed one by one in a cycle. When the feeding tray mechanism is in operation, the clamping mechanism and the abutment mechanism installed on the feeding tray mechanism are connected. When the feeding tray mechanism rotates, the clamping mechanism can perform clamping or unloading actions to clamp and fix or unload the heating tray to meet the drilling requirements. The loading and unloading robotic arm 3 set on the drilling worktable 1 can remove the drilled heating tray from the clamping mechanism, and then place the undrilled heating tray on the unloaded clamping mechanism for feeding and drilling, which meets the needs of automated production and improves the usage effect.

[0055] Please see Figure 5 As a further embodiment of the present invention, the mounting mechanism includes a bearing whose outer ring is fixedly connected to the drilling worktable 1 and a rotating shaft 4 fixed to the inner ring of the bearing. The rotating shaft 4 is rotatably connected to the drilling worktable 1 through the bearing.

[0056] In this embodiment, the outer ring of the bearing is fixedly connected to the cavity of the drilling workbench 1. The rotating shaft 4 can rotate and adjust on the drilling workbench 1 through the bearing to meet the rotation requirements of the feeding plate mechanism, so that multiple heating plates can move to the drilling station one by one for processing.

[0057] Please see Figure 3 As a further embodiment of the present invention, the feeding tray mechanism includes a turntable 5 centrally mounted at the top of the rotating shaft 4 and a plurality of support seats 7 arranged in a circular array at equal intervals on the turntable 5.

[0058] A gear ring 6 is fixedly connected to the outer edge of the turntable 5, and multiple sliding grooves 8 are arranged in a ring array on the turntable 5 at each of the support seats 7 locations.

[0059] In this embodiment, the gear ring 6 provided on the outer wall of the turntable 5 is used to connect with the linkage mechanism. The multiple support seats 7 provided on the turntable 5 are used to support the placement of the heating plates. The sliding groove 8 opened around the circumference of the support seat 7 on the turntable 5 satisfies the motion adjustment of the clamping mechanism and ensures the effect of feeding multiple heating plates one by one.

[0060] Please see Figure 12 , Figure 13 As a further embodiment of the present invention, the linkage mechanism includes a gear 33 meshing with the gear ring 6, a plug-in post 31 connected to the gear 33, and a linkage rod 29 connected to the gear 33.

[0061] The top of the linkage rod 29 is fixedly connected to the mounting plate 30, which is installed on one of the drilling machines 2. The outer wall of the linkage rod 29 is provided with a spiral groove.

[0062] A ratchet 32 ​​is fixedly connected to the top of the plug post 31. The ratchet 32 ​​is connected to the gear 33. A semi-circular protrusion 34 is fixedly connected to the inner wall of the ratchet 32. The semi-circular protrusion 34 is slidably connected to the spiral groove.

[0063] In this embodiment, the linkage 29 is mounted on one of the drilling machines 2 via the mounting plate 30. The ratchet 32 ​​on the insertion post 31 is unidirectionally connected to the gear 33. When the drilling machine 2 descends to drill the heating plate on the turntable 5, the ratchet 32 ​​and gear 33 are slipping, so the drilling machine 2 will not drive the gear 33 to rotate during descent. When the drilling machine 2 finishes drilling and rises, the spiral groove on the outer wall of the linkage 29 abuts against the semi-circular protrusion 34, causing the ratchet 32 ​​to rotate. At this time, the ratchet 32 ​​meshes with the gear 33, allowing the gear 33 to rotate. The gear 33 meshes with the gear ring 6, thus enabling the gear 33 to rotate. When the 3rd part rotates, the gear ring 6 can rotate. Through the length design of the linkage rod 29 and the coordination of the lifting height of the drilling machine 2, after the drilling machine 2 is raised to the position, the rotation range of the turntable 5 is just enough to make the previous station rotate to the next station. This allows the multiple heating plates placed on the turntable 5 to move to the drilling station one by one for drilling. A limit mechanism is set on the drilling worktable 1 at the part of the drilling machine 2 connected to the linkage rod 29. After the drilling machine 2 is raised to the position, the limit mechanism can limit the turntable 5 to prevent it from rotating due to inertia. The limit mechanism is an existing publicly available technical means and will not be described in detail here.

[0064] Please see Figures 6-9 As a further embodiment of the present invention, the clamping mechanism includes a sliding block 14 slidably connected in the sliding groove 8, a collar 18 connected to the sliding block 14, a guide post 22 connected to the collar 18, and an adjustment assembly connected to the guide post 22.

[0065] A clamping plate 15 is fixedly connected to one side of the top of the sliding block 14. The bottom of the clamping plate 15 slides against the surface of the turntable 5. A boss 16 is symmetrically fixedly connected to the bottom end of the sliding block 14. A rolling roller 17 is rotatably connected to the boss 16. The rolling roller 17 abuts against the bottom surface of the turntable 5.

[0066] A connecting rod 20 is provided between the sliding block 14 and the collar 18. One end of the connecting rod 20 is rotatably connected to the bottom end of the sliding block 14, and the other end is rotatably connected to a rotating seat fixedly connected to the outer wall of the collar 18.

[0067] A central block 19 is fixedly connected to the center of the collar 18, and a gear post 21 is provided at the bottom of the central block 19. The top end of the gear post 21 is rotatably connected to the central block 19.

[0068] The collar 18 is slidably sleeved with the guide post 22. The top of the guide post 22 is fixedly connected to the turntable 5. The guide post 22 has a lifting groove 23 that is slidably connected to the center block 19. The guide post 22 has a notch 24. A screw 25 is slidably connected in the lifting groove 23. The screw 25 is threadedly connected to the threaded hole at the bottom of the gear post 21. An abutment rod 26 is fixedly connected to the bottom of the screw 25. The abutment rod 26 is slidably connected in the lifting groove 23. Both ends of the abutment rod 26 extend out of the outer wall of the guide post 22.

[0069] Please see Figure 11 The adjustment assembly includes an adjustment ring 27 rotatably connected to the notch 24 and an inner ring gear 28 disposed on the inner wall of the adjustment ring 27, the inner ring gear 28 meshing with the gear post 21.

[0070] In this embodiment, the sliding block 14 is slidably connected within the sliding groove 8, the bottom of the clamping plate 15 slidably abuts against the surface of the turntable 5, and the rolling roller 17 rotatably mounted on the boss 16 slidably abuts against the bottom surface of the turntable 5. Through the design of the clamping plate 15 and the boss 16, the sliding block 14 can only move horizontally within the sliding groove 8, preventing any flipping or shaking. The bottom end of the sliding block 14 is rotatably connected to one end of the connecting rod 20, and the other end of the connecting rod 20 is rotatably connected to a rotating seat fixedly connected to the outer wall of the collar 18. When the collar 18 descends on the guide post 22, it can... This allows the connecting rod 20 to change from its original horizontal state to an inclined state. The greater the inclination angle of the connecting rod 20, the greater the moving distance of the sliding block 14 in the sliding groove 8, thereby making the folding area of ​​the clamping plate 15 of the annular array smaller. This enables the clamping and fixing of heating plates of different sizes. When the collar 18 rises from the guide post 22, the clamping plate 15 will expand and lose its clamping and fixing of the heating plate. Through this design, the linkage clamping and fixing of the heating plate is satisfied, reducing the need for a separate drive source for clamping and fixing the heating plate, thus reducing cost investment and failure rate.

[0071] By adjusting the rotation of the component, the clamping range of multiple clamping mechanisms can be adjusted. When the adjusting ring 27 is rotated, the inner ring gear 28 meshes with the gear post 21 and rotates. Since the top of the gear post 21 is rotatably connected to the collar 18, and the bottom of the gear post 21 is threadedly connected to the screw 25, and the abutment rod 26 at the bottom of the screw 25 is slidably connected in the lifting groove 23, the screw 25 can only slide vertically on the guide post 22 and cannot rotate due to the limiting effect of the abutment rod 26. Therefore, when the adjusting ring 27 is rotated, the clamping range of multiple clamping mechanisms can be adjusted. The gear column 21 on the mechanism rotates, which forces the screw 25, which is threaded to the bottom of the gear column 21, to rise and fall within the lifting groove 23. This controls the initial height between the contact rod 26 and the collar 18, expanding the clamping range of the clamping mechanism on the heating plate. This makes it suitable for clamping and fixing heating plates of different sizes, meeting usage requirements. Furthermore, the design of the clamping mechanism reduces the area of ​​the clamping plate obstructed when clamping and fixing the heating plate, preventing the drilling effect on the heating plate from being affected by obstruction during drilling.

[0072] Please see Figure 4 , Figure 10 As a further embodiment of the present invention, the abutting mechanism includes a first support ring 9 fixedly connected to the drilling workbench 1 and a second support ring 10 fixedly connected to the outer ring of the first support ring 9 on the drilling workbench 1.

[0073] A first adjustment groove 11 and a second adjustment groove 12 are provided on the opposite surfaces of the first support ring 9 and the second support ring 10. A third adjustment groove 13 is symmetrically provided on the first support ring 9 and the second support ring 10 on both sides of the second adjustment groove 12. The height of the first adjustment groove 11 is lower than that of the second adjustment groove 12. The third adjustment groove 13 is inclined to connect the first adjustment groove 11 and the second adjustment groove 12.

[0074] The distance between the first support ring 9 and the second support ring 10 is the same as the diameter of the guide post 22.

[0075] In this embodiment, the diameter of the guide post 22 is the same as the distance between the first support ring 9 and the second support ring 10. Therefore, the guide post 22 can slide within the distance between the first support ring 9 and the second support ring 10. The height of the first adjusting groove 11 is lower than the height of the second adjusting groove 12 on the first support ring 9 and the second support ring 10. The third adjusting groove 13 acts on both ends of the second adjusting groove 12, so that the second adjusting groove 12 and the first adjusting groove 11 can be transitionally connected to meet the requirements of continuous use. Through the design, the loosening and clamping effect of the clamping mechanism when the feeding plate mechanism rotates can be adjusted and controlled to meet the requirements of linkage use, reduce the cost of setting up a separate clamping and fixing drive source to fix the heating plate, and improve the use effect.

[0076] Please see Figure 5 As a further embodiment of the present invention, the two ends of the abutment rod 26 are respectively slidably connected to the first adjustment groove 11, the second adjustment groove 12 and the third adjustment groove 13 opened on the first support ring 9 and the second support ring 10.

[0077] In this embodiment, the two ends of the abutment rod 26 are slidably connected to the first adjustment groove 11, the second adjustment groove 12, and the third adjustment groove 13 respectively opened on the first support ring 9 and the second support ring 10. When the turntable 5 rotates, the abutment rod 26 will slide and abut within the first adjustment groove 11, the second adjustment groove 12, and the third adjustment groove 13. When the abutment rod 26 slides and the first adjustment groove 11 slides to the third adjustment groove 13, it will slide along the path of the third adjustment groove 13. At this time, the abutment rod 26 will rise. When the abutment rod 26 moves to the second adjustment groove 12, the abutment rod 26 rises to its maximum height. When the abutment rod 26 rises, it will cause the screw 25 to rise, thereby causing the collar 18 to be lifted. At this time, the force of the inner ring gear 28 on the connecting rod 20 causes the connecting rod 20 to expand the sliding block 14 outward. When the rotating plate 15 is rotated, the clamping plate 15 of the circular array will loosen or release the clamping of the heating plate, so that the loading and unloading robot arm 3 can remove the drilled heating plate from the turntable 5 and then place the un-drilled heating plate in the current position. When the turntable 5 rotates, the abutment rod 26 can slide from the second adjustment groove 12 to the third adjustment groove 13. When the abutment rod 26 moves to the part of the first adjustment groove 11, the abutment rod 26 drops to the bottom, forcing the screw 25 to drop on the guide post 22, so that the collar 18 acts on the connecting rod 20, causing the sliding block 14 of the circular array around the collar 18 to retract inward. The clamping plate 15 clamps and fixes the heating plate, which can improve the drilling accuracy of the heating plate when drilling, and prevent the heating plate from loosening during drilling due to the heating plate not being fixed firmly, thus affecting the drilling quality.

[0078] The drilling process using a drilling apparatus described above for taking holes circumferentially on a heating plate includes the following steps:

[0079] Step 1: The heating plate is placed on the turntable 5 by the loading and unloading robotic arm 3. The clamping plate 15 located at the loading and unloading robotic arm 3 is in an expanded state at this time.

[0080] Step 2: When the drilling machine 2 is lowered to drill the heating plate on the turntable 5 and then raised, it can drive the gear 33 to rotate, causing the turntable 5 to rotate, so that the multiple heating plates placed on the turntable 5 can supply the drilling station.

[0081] Step 3: When the abutment rod 26 moves from the second adjustment groove 12 to the first adjustment groove 11, it can drive the collar 18 to descend on the guide post 22. At this time, the multiple connecting rods 20 connected to the collar 18 can move together to make the multiple clamping plates 15 gather inward.

[0082] Step 4: The converging clamping plate 15 can clamp and fix the heating plate placed on the turntable 5, so that the heating plate is stably placed on the turntable 5 for drilling.

[0083] Step 5: The processed heating plate moves to the loading / unloading robotic arm 3 under the rotation of the turntable 5. At this time, the clamping plate 15 expands outward and loses its grip on the heating plate. The loading / unloading robotic arm 3 can remove the drilled heating plate and put in an un-drilled heating plate for subsequent drilling operations.

[0084] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.

2. The drilling process using the drilling device for circumferential drilling on a heating plate as described in claim 1, characterized in that, Includes the following steps: Step 1: The heating plate is placed on the turntable by the loading and unloading robotic arm. The clamping plate located at the loading and unloading robotic arm is in an expanded state at this time. Step 2: When the drilling machine is lowered to drill holes in the heating plates on the turntable and then raised, it can drive the gears to rotate, causing the turntable to rotate, so that the multiple heating plates placed on the turntable can supply power to the drilling station. Step 3: When the abutment rod moves from the second adjustment groove to the first adjustment groove, it can drive the collar to descend on the guide post. At this time, the multiple connecting rods connected to the collar can move together to make the multiple clamping plates gather inward. Step 4: The converging clamping plates can clamp and fix the heating plate placed on the turntable, so that the heating plate is stably placed on the turntable for drilling. Step 5: The processed heating plate moves to the loading / unloading robotic arm under the rotation of the turntable. At this time, the clamping plate expands outward and loses its grip on the heating plate. The loading / unloading robotic arm can then remove the drilled heating plate and place an un-drilled heating plate in it for subsequent drilling operations.
