Description

Technical Field

[0001] This invention relates to the field of resistance strip processing technology, and in particular to a high-temperature alloy resistance strip drilling machine and its usage method. Background Technology

[0002] High-temperature alloy resistance strip is an electrical heating element that converts electrical energy into heat energy. It is usually made into a flat strip and is made of special high-temperature alloy material, which enables it to work stably for a long time in harsh environments with high temperature and high corrosion.

[0003] Existing technologies, such as the high-temperature alloy resistance strip drilling machine disclosed in CN116652233A, use a moving structure to lower the mounting frame, allowing the drill bit to move to the drilling position on the resistance strip. However, just as the drill bit is about to penetrate the resistance strip, the strip bends and deforms due to the axial force of the drill bit, causing the resistance strip to be "pushed" open by the drill bit. The portion of the resistor strip material that has been "bombed" open but not removed by the drill bit's cutting edge will remain at the exit edge of the hole, forming an exit burr, which affects the processing quality and subsequent performance of the resistor strip. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art where the resistance strip bends and deforms due to the axial force of the drill bit when the drill bit is about to penetrate the resistance strip, forming an exit burr. Therefore, this invention proposes a high-temperature alloy resistance strip drilling machine and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-temperature alloy resistance strip drilling machine includes a machine base, a sliding frame is provided on the machine base, an electric telescopic rod II is provided in the sliding frame, a rotating seat is fixedly installed at the bottom end of the electric telescopic rod II, an mounting platform is fixedly installed at the bottom end of the rotating seat, and a clamping component is provided at the bottom end of the mounting platform. The clamping component includes clamping plates, and the resistance strip is clamped by the opposite movement of the two clamping plates. The clamping plate is provided with a plurality of support rings arranged sequentially from the inside to the outside to support the resistor strip. The clamping plate is provided with a limiting component to limit the axial movement of the support rings. The limiting component includes multiple racks disposed on the support ring. The multiple racks move towards the center of the support ring and cover the support ring to limit its movement.

[0006] Preferably, a plurality of mounting posts are fixedly installed on the clamping plate, and a fixing platform is fixedly installed at the ends of the plurality of mounting posts. A driving component that drives the support ring to move axially is provided on the fixing platform. The driving component includes a rotary motor and a drive gear fixedly installed at the output end of the rotary motor. A threaded rod is fixedly installed at the bottom end of the drive gear. A threaded bushing is provided on the outer wall of the threaded rod, and the threaded rod and the threaded bushing are threadedly connected. The bottom end of the threaded bushing is fixedly connected to a support ring.

[0007] Preferably, a plurality of connecting rods are rotatably mounted on the clamping plate, and a rotating gear and a drive gear are respectively fixedly mounted at both ends of the plurality of connecting rods, wherein the rotating gear and the drive gear are meshed together.

[0008] Preferably, the clamping plate has multiple placement slots, the rotating gear is disposed in the placement slot, a limiting frame is fixedly installed in the placement slot, a rack is slidably disposed in the limiting frame, and the rack and the rotating gear are meshed together.

[0009] Preferably, the support ring is provided with a limiting seat and a sliding rod, and the sliding rod is slidably disposed in the limiting seat. The sliding rod slides to the top of the limiting seat and the limiting seat drives the support ring to move as the sliding rod continues to slide.

[0010] Preferably, two sliding rails are fixedly installed at the bottom of the mounting platform, and sliding blocks are slidably arranged on both sliding rails. A connecting frame is fixedly installed on both sliding blocks. A bidirectional lead screw is threaded inside the connecting frame. The distance between the two connecting frames is adjusted by rotating the bidirectional lead screw through the output end of the drive motor.

[0011] Preferably, a sliding seat is also fixedly installed at the bottom of the mounting platform, and a drilling machine is slidably disposed in the sliding seat.

[0012] Preferably, an electric telescopic rod is fixedly installed at the bottom end of the sliding frame, and an installation plate is fixedly installed at the bottom end of the electric telescopic rod. A rotating plate and a limiting plate are provided at the bottom end of the installation plate. The rotating plate is rotatably installed at the bottom end of the installation plate, and the limiting plate is fixedly installed at the bottom end of the installation plate.

[0013] Preferably, a rotating rod one is rotatably mounted on the bottom end of the mounting plate, and a rotating rod two is rotatably mounted on the rotating plate. The ends of the rotating rod one and the rotating rod two are rotatably connected. A servo motor is fixedly mounted on the upper end of the mounting plate, and the output end of the servo motor is fixedly connected to the other end of the rotating rod one.

[0014] A method for using a high-temperature alloy resistance band drilling machine includes the following operating steps: Step S1: Place the high-temperature alloy resistance strip to be processed on the machine platform, move the sliding frame to move the clamping plate above the area to be drilled on the resistance strip, turn on the electric telescopic rod two to push the mounting table down, so that the two clamping plates are lowered to both sides of the resistance strip, and then turn on the drive motor to drive the bidirectional lead screw to rotate, so that the two connecting frames drive the clamping plates to move towards each other until they are tightly attached to both sides of the resistance strip, thus completing the clamping and providing stable support. Step S2: Turn on the drilling machine and move it in the sliding seat at the set feed speed toward the resistance strip. Just as the drill bit is about to penetrate the resistance strip, the support ring below it provides reverse support for the resistance strip, preventing the resistance strip from bending and deforming due to the axial force of the drill bit. This allows the cutting edge of the drill bit to completely shear off the material in the hole instead of "blowing" it open, thus suppressing the generation of exit burrs. Step S3: Turn on the rotary motor to make the drive gear rotate. When the drive gear rotates, it drives the rotary gear to rotate, and through the connecting rod, it drives the rotary gear to rotate. The rotary gear drives the rack to move into the placement slot under the limit of the limit frame, so that the rack releases the limit on the support ring one by one. In step S4, when the drive gear rotates, it drives the threaded rod to rotate. When the threaded rod rotates, it drives the threaded bushing to move along the axial direction of the threaded rod. The threaded rod drives the support ring to move synchronously. The support ring drives the sliding rod to slide within the limit seat. In conjunction with the rack, the limit on the support ring is released one by one, so that multiple limit seats move upward one by one. This allows the support surface formed by the support ring to dynamically adapt to the constantly changing hole diameter during the drill bit's drilling process, always providing optimal close-range support for the drill bit's exit area, further ensuring the hole quality. Step S5: When the resistor strip itself is bent and its inner angle is too small to accommodate the drilling machine, the servo motor is turned on. The servo motor drives the first rotating rod to rotate, which in turn pushes the rotating plate to rotate outward through the second rotating rod, thereby increasing the inner angle of the bent part of the resistor strip and creating enough operating space for the drilling equipment.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention provides reverse support for the resistance band by setting multiple dynamically adjustable support rings in the clamping plate at the moment when the drill bit is about to penetrate the resistance band, preventing the resistance band from bending and deforming due to the force applied in the axial direction of the drill bit, ensuring that the cutting edge of the drill bit can complete the complete shearing of the material rather than tearing it, and suppressing the generation of exit burrs.

[0016] 2. The present invention enables the support ring to release the limiting position and move upward sequentially and in stages during the drilling process, so that the support surface can intelligently adapt to the constantly changing hole diameter during the drilling process, and always provide optimal close-range support for the drill bit exit area, thereby improving the hole processing quality.

[0019] 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.

[0020] Reference Figures 1-10A high-temperature alloy resistance strip drilling machine includes a machine base 1. The machine base 1 has a chip discharge hole 2 for timely discharge of the waste chips generated during drilling of the high-temperature alloy resistance strip, so as to avoid the accumulation of waste chips affecting the processing accuracy or damaging the equipment. Two parallel guide rails 3 are fixedly installed on the machine base 1. A sliding frame 4 is slidably arranged on the two guide rails 3. By driving the sliding frame 4 to slide along the guide rails 3, the horizontal position of the clamping and drilling module installed below it on the machine base can be adjusted as a whole, so that it is aligned with the area to be processed of the resistance strip. An electric telescopic rod 5 is fixedly installed at the bottom of the sliding frame 4. An installation plate 501 is fixedly installed at the bottom end of the electric telescopic rod 5. An articulated opening mechanism is provided at the bottom end of the installation plate 501, which consists of a rotating plate 505 and a limiting plate 506. The rotating plate 505 is mounted on the bottom of the mounting plate 501 via a hinge, while the limiting plate 506 is fixedly mounted on the bottom of the mounting plate 501 to limit the maximum rotation angle of the rotating plate 505 and prevent it from rotating excessively and damaging the resistor strip. The driving part of the spreading mechanism includes: a rotating rod 503 rotatably mounted on the bottom of the mounting plate 501, a rotating rod 504 rotatably mounted on the rotating plate 505, and a servo motor 502 fixedly mounted on the upper end of the mounting plate 501. The output end of the servo motor 502 is fixedly connected to the other end of the rotating rod 503. When the servo motor 502 starts, it drives the rotating rod 503 to rotate, which in turn pushes or pulls the rotating plate 505 through the rotating rod 504, causing it to rotate around the hinge point, thereby increasing or decreasing the angle between it and the limiting plate 506. To prevent the resistor strip from being bent and its inner gap from being too small to accommodate the drilling machine 8, the spreading mechanism expands its inner angle, creating space for drilling operations.

[0021] An electric telescopic rod 6 is also fixedly installed inside the sliding frame 4. A rotating seat 601 is fixedly installed at the bottom end of the electric telescopic rod 6, and an installation platform 602 is fixedly installed at the bottom end of the rotating seat 601. By extending and retracting the electric telescopic rod 6, the entire installation platform 602 and the components below it can be moved vertically to adjust the drilling height or bring the clamping parts closer to the resistor strip. The rotating seat 601 allows the mounting table 602 to rotate within a certain angle. This function, combined with the horizontal movement of the sliding frame 4, enables the drilling machine 8 to be flexibly positioned on the other side of the resistance band or on the processing surface at different angles, effectively solving the problem that the drilling equipment cannot be positioned due to the resistance band being stretched open. The bottom of the rotating seat 601 is fixedly installed with the mounting platform 602. The rotating seat 601 drives the mounting platform 602 to rotate, and the sliding frame 4 slides to place the drilling machine 8 at the opening on the other side of the high-temperature alloy resistance strip to drill holes in the high-temperature alloy resistance strip. This prevents the high-temperature alloy resistance strip from being unable to be drilled because the distance at the bend of the high-temperature alloy resistance strip is insufficient to place the drilling machine 8 after the rotating plate 505 opens it. The mounting platform 602 is provided with a clamping component at its bottom end. The clamping component includes a clamping plate 9. The resistor strip is clamped by the opposite movement of the two clamping plates 9 and a supporting force is provided for the resistor strip. Multiple support rings 913 are arranged in sequence from the inside to the outside inside the clamping plate 9. The outermost support ring 913 is fixedly installed on the inner wall of the clamping plate 9 to prevent the entire set of support rings from falling off. These support rings 913 together form a continuous support plane in the initial state. The limiting component includes multiple racks 912 disposed on the support ring 913. The multiple racks 912 move toward the center of the support ring 913 and cover the support ring 913 to limit the axial movement of the support ring 913.

[0022] Multiple mounting posts 901 are fixedly installed on the clamping plate 9, and a fixing platform 902 is fixedly installed at the ends of the multiple mounting posts 901. A driving component that drives the support ring 913 to move axially is provided on the fixing platform 902. The driving component includes a rotary motor 903 and a drive gear 904 fixedly installed at the output end of the rotary motor 903. The rotary motor 903 is fixedly installed on the fixed platform 902. A threaded rod 906 is fixedly installed at the bottom end of the drive gear 904. A threaded bushing 907 is provided on the outer wall of the threaded rod 906, and the threaded rod 906 and the threaded bushing 907 are threadedly connected. The bottom end of the threaded bushing 907 is fixedly connected to the support ring 913.

[0023] Multiple connecting rods 908 are rotatably mounted on the clamping plate 9. Rotating gears 905 and 909 are fixedly mounted at both ends of the multiple connecting rods 908 respectively. The rotating gears 905 and the drive gears 904 are meshed and connected. The rotation of the rotating gears 905 is transmitted to the rotating gears 909 through the connecting rods 908, so that the rotating gears 909 rotate.

[0024] The clamping plate 9 has multiple placement slots 910, in which the rotating gear 909 is placed. Each placement slot 910 is fixedly installed with a limit frame 911. The rack 912 is slidably disposed in the limit frame 911 and meshes with the rotating gear 909. In the initial state, these racks 912 extend under the drive of the rotating gear 909 and cover the corresponding support ring 913, forming an axial limit to prevent it from moving when not in operation.

[0025] Each support ring 913 is fixedly installed with a limiting seat 914. Adjacent support rings are connected by a sliding rod 915. The sliding rod 915 can slide within the limiting seat 914, so that the movement of the innermost support ring 913 can be transmitted to the outer support rings in sequence, realizing their sequential action.

[0026] Two sliding rails 603 are fixedly installed at the bottom of the mounting platform 602. Sliding blocks 604 are slidably mounted on both sliding rails 603, and connecting frames 606 are fixedly mounted on both sliding blocks 604. This allows the sliding blocks 604 to move via the connecting frames 606. A bidirectional lead screw 607 is threaded inside the connecting frames 606. The bidirectional lead screw 607 is rotated by the output of the drive motor 608 to adjust the distance between the two connecting frames 606. The sliding blocks 604 move the fixed frame 605 fixedly installed at the bottom. The fixed frame 605 moves the clamping plates 9 fixedly connected at the bottom towards each other, so that the two clamping plates 9 clamp and support the high-temperature alloy resistance strip.

[0027] A sliding seat 7 is also fixedly installed at the bottom of the mounting platform 602. The drilling machine 8 is slidably set in the sliding seat 7. By controlling the feed of the drilling machine 8 in the sliding seat 7, the clamped resistance strip can be drilled. When the drill bit is about to penetrate the last 20% of the resistance strip thickness, the control system can instruct the drilling machine 8 to adopt a slower feed speed to further reduce impact and optimize the hole quality.

[0028] An electric telescopic rod 5 is fixedly installed at the bottom of the sliding frame 4. An installation plate 501 is fixedly installed at the bottom of the electric telescopic rod 5. A rotating plate 505 and a limiting plate 506 are provided at the bottom of the installation plate 501. The rotating plate 505 is rotatably installed at the bottom of the installation plate 501. The limiting plate 506 is fixedly installed at the bottom of the installation plate 501. The rotation of the rotating plate 505 is limited by the limiting plate 506 to prevent the rotating plate 505 from rotating too much and damaging the structure of the high-temperature alloy resistance strip.

[0029] A rotating rod 503 is rotatably mounted on the bottom of the mounting plate 501, and a rotating rod 504 is rotatably mounted on the rotating plate 505. The ends of the rotating rod 503 and the rotating rod 504 are rotatably connected. A servo motor 502 is fixedly mounted on the upper end of the mounting plate 501, and the output end of the servo motor 502 is fixedly connected to the other end of the rotating rod 503.

[0030] The movements of electric telescopic rod 1 (5), electric telescopic rod 2 (6), servo motor 502, rotary motor 903, drive motor 608, and drilling machine 8 can all be coordinated and controlled by the central controller to realize automated processing, ensure precise timing of actions, and improve processing efficiency and consistency.

[0031] It should be noted that the specific models and specifications of the electric telescopic pole 1, electric telescopic pole 2, rotating seat, drilling machine and sliding seat need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated.

[0032] The functional principle of this invention can be explained through the following operational methods: Place the high-temperature alloy resistance strip to be processed on the machine base 1, move the sliding frame 4 to move the clamping plate 9 above the area to be drilled on the resistance strip, activate the electric telescopic rod 6 to push the mounting table 602 down, so that the two clamping plates 9 are lowered to both sides of the resistance strip, then activate the drive motor 608 to drive the bidirectional lead screw 607 to rotate, so that the two connecting frames 606 drive the clamping plates 9 to move towards each other until they are tightly fitted to both sides of the resistance strip, thus completing the clamping and providing stable support. Turn on the drill 8 and move it in the sliding seat 7 at a set feed speed toward the resistance band. At the moment when the drill bit is about to penetrate the resistance band, the support ring 913 below it provides reverse support for the resistance band, preventing the resistance band from bending and deforming due to the axial force of the drill bit. This allows the cutting edge of the drill bit to completely shear off the material in the hole instead of "blowing" it open, thus suppressing the generation of exit burrs. Turn on the rotary motor 903 to make the drive gear 904 rotate. When the drive gear 904 rotates, it drives the rotary gear 905 to rotate, and drives the rotary gear 909 to rotate through the connecting rod 908. The rotary gear 909 drives the rack 912 to move into the placement slot 910 under the limit of the limit frame 911, so that the rack 912 releases the limit on the support ring 913 one by one. When the drive gear 904 rotates, it drives the threaded rod 906 to rotate. When the threaded rod 906 rotates, it drives the threaded bushing 907 to move along the axial direction of the threaded rod 906. The threaded rod 906 drives the support ring 913 to move synchronously. The support ring 913 drives the sliding rod 915 to slide within the limiting seat 914. In conjunction with the rack 912, the limiting seats 914 are released one by one, so that the multiple limiting seats 914 move upward one by one. This allows the support surface formed by the support ring 913 to dynamically adapt to the constantly changing hole diameter during the drill bit's drilling process, always providing optimal close-range support for the drill bit's exit area, and further ensuring the hole quality. When the resistor strip itself is bent and its inner angle is too small to accommodate the drilling machine 8, the servo motor 502 is turned on. The servo motor 502 drives the rotating rod 1 503 to rotate, which in turn pushes the rotating plate 505 to rotate outward through the rotating rod 2 504, thereby increasing the inner angle of the bent part of the resistor strip and creating enough operating space for the drilling equipment.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

Step S4, when the drive gear (904) rotates, the threaded rod (906) is driven to rotate, the threaded rod (906) drives the threaded shaft sleeve (907) to move axially along the threaded rod (906), the threaded rod (906) drives the support ring (913) to move synchronously, the support ring (913) drives the sliding rod (915) to slide in the limiting seat (914), and cooperate with the rack (912) to release the limiting of the support ring (913) one by one, make a plurality of limiting seats (914) move up one by one, so that the support surface formed by the support ring (913) can dynamically adapt to the changing hole diameter in the drilling process of the drill bit, and always provide the best close-range support for the drill bit outlet area, further guarantee the hole quality; Step S5, when encountering a resistance band itself in a bent shape, and the inner angle is too small to accommodate the drilling machine (8), the servo motor (502) is started, the servo motor (502) drives the rotating rod one (503) to rotate, and then the rotating rod two (504) pushes the rotating plate (505) to rotate outward, thereby increasing the inner angle of the resistance band bending part, and creating enough operation space for the drilling equipment.
