The drill bit of the thermal fusion drill is made of tungsten carbide cemented carbide, which, after heat treatment, can maintain wear resistance at high temperatures of 600℃ and high speeds of 1500-3000r / min. The dual-spindle structure of the thermal fusion drill enables simultaneous drilling and tapping. The thermal fusion drill is also equipped with a forced cooling system to prevent the drill bit from overheating. The thermal fusion drill is mainly used for chipless machining or thread strengthening, and can complete drilling, bushing forming, and tapping in a single clamping operation. The thermal fusion drill is mainly used in the fields of automobile manufacturing, aerospace, and medical devices.

[0003] In the processing of automotive front longitudinal beams, existing hot melt drilling machines require manual installation or deployment of protective facilities, which is cumbersome and time-consuming, making it difficult to quickly form effective high-heat protection and affecting operational efficiency. The automotive front longitudinal beam has a complex structure and often requires alignment for multi-directional drilling. After fixing the workpiece, existing hot melt drilling machines require the entire workpiece to be removed from the fixture and readjusted and re-clamped when the angle needs to be adjusted, interrupting the processing flow. Moreover, the disassembly and assembly process introduces positioning errors, resulting in a decrease in hole accuracy and affecting the processing quality of the product. Utility Model Content

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a hot melt drilling machine for processing automotive front longitudinal beams with protective function, including an operating table 1, a guide rail 2 connected to the top of the operating table 1, a protective mechanism 5, the protective mechanism 5 including multiple protective plates 507 disposed above the operating table 1, two adjacent protective plates 507 being configured to overlap each other, the protective plates 507 providing high temperature isolation during hot melt drilling, and an adjustment mechanism 6, the adjustment mechanism 6 including a movable seat 601 slidably connected to the guide rail 2, a rotating block 602 rotatably connected to the top of the movable seat 601, a guide rod 603 connected to one side of the outer wall of the rotating block 602, the rotation of the rotating block 602 being driven by the movement of the guide rod 603, so that the adjustment mechanism 6 can adjust the angle of the automotive front longitudinal beam by changing its own position.

[0017] The top of the control panel 1 is connected to a mounting plate 501. Two slide rails 502 are connected to one side of the outer wall of the mounting plate 501. A sliding rod 503 is slidably connected to the outer wall of the slide rail 502. A mounting bracket 506 is connected to the top of the sliding rod 503. The bottom outer wall of the mounting bracket 506 is connected to the top outer wall of the protective plate 507.

[0018] A movable plate 508 is slidably connected to one side of the outer wall of the sliding rod 503. Multiple travel grooves 504 are provided on the outer wall of the movable plate 508. A linkage rod 505 is connected to one side of the outer wall of the sliding rod 503. The outer wall of the linkage rod 505 is slidably connected to the inner wall of the travel groove 504.

[0019] A movable block 509 is connected to one side of the outer wall of the movable plate 508. Two limiting rods 510 are connected to the top of the operating table 1. One end of the limiting rod 510 penetrates the movable block 509. An electric push rod 511 is installed on the mounting plate 501 through the column. The telescopic part of the electric push rod 511 is connected to the outer wall of the movable block 509.

[0020] Specifically, the electric push rod 511 drives the moving block 509 to move via its telescopic end. When the electric push rod 511 pushes the moving block 509 downward along the direction of the limiting rod 510, the moving block 509 drives the moving plate 508 to descend synchronously. The central stroke groove 504 of the five stroke grooves 504 is vertical, and the stroke grooves 504 on both sides of the central stroke groove 504 are inclined relative to the central stroke groove 504. When the moving plate 508 moves downward, the linkage rod 505 slides from the bottom end of the stroke groove 504 to the top end of the stroke groove 504. The central sliding rod 503 of the five sliding rods 503 remains relatively fixed with the slide rail 502, and the sliding rods 503 on both sides of the central sliding rod 503 move away from the central sliding rod 503 along the track direction of the slide rail 502. In the initial state, the two adjacent protective plates 507 overlap and are stored together. When the sliding rods 503 on both sides of the central sliding rod 503 move away from the central sliding rod 503, they drive the corresponding protective plates 507 to move synchronously, causing the protective plates 507 to move away from each other, thus unfolding the protective mechanism 5 and expanding the protective range of the protective plates 507. Similarly, when the electric push rod 511 pulls the moving block 509 upward through the telescopic end, it can cause the protective mechanism 5 to retract and reduce the protective range of the protective plates 507.

[0021] It should be noted that the electric actuator 511 described above is a new type of linear actuator composed of an electric motor, a actuator, and a control device. It is an electric drive device that converts the rotational motion of the electric motor into the linear reciprocating motion of the actuator. This part is well-known technology in the field and will not be described in detail here.

[0022] A clamp 604 is connected to one side of the outer wall of the rotating block 602. A guide plate 605 is connected to the top of the operating table 1. A guide groove 606 is opened on the outer wall of the guide plate 605. One end of the guide rod 603 passes through the guide groove 606. A slide table 3 is slidably connected to the top of the side wall of the operating table 1. A robotic arm 4 is connected to one side of the slide table 3.

[0023] The top of the control panel 1 is connected to two mounting bases 608, and a lead screw 609 is rotatably connected between the two mounting bases 608. A connecting base 607 is provided on the outside of the lead screw 609. One side of the outer wall of the connecting base 607 is connected to one side of the outer wall of the movable base 601. A motor 610 is installed on one side of the outer wall of the mounting base 608, and the output end of the motor 610 is connected to one end of the lead screw 609.

[0024] Specifically, the external thread on the outer wall of the lead screw 609 meshes with the internal thread on the inner wall of the connecting seat 607, allowing the connecting seat 607 to move along the body of the lead screw 609 when the lead screw 609 rotates. In the initial state, the clamp 604 is perpendicular to the horizontal plane, and the guide rod 603 is located at the higher end of the moving groove. The motor 610 drives the lead screw 609 to rotate through its output end, and the connecting seat 607 moves along the body of the lead screw 609. The connecting seat 607 drives the moving seat 601 to move along the track direction of the guide rail 2. The moving seat 601 drives the rotating block 602 to move synchronously, and the guide rod 603 follows the moving block 509 and moves synchronously along the direction of the guide groove 606. When the guide rod 603 moves along the inclined section of the guide groove 606, the guide rod 603 drives the rotating block 602 to rotate through the plate. The rotating block 602 drives the clamp 604 to rotate, so that the angle between the clamp 604 and the horizontal plane gradually decreases. When the guide rod 603 moves to the groove body of the guide groove 606 at the lower position and parallel to the horizontal plane, the clamp 604 rotates to be horizontal with the horizontal plane. The slide table 3 moves synchronously with the moving seat 601 under the control of the external system. The end of the mechanical arm 4 connected to the side wall of the slide table 3 is connected to a hot melt drill bit. During the movement, the hot melt drill bit drills holes at different angles on the front longitudinal beam of the car held by the clamp 604.

[0025] It should be noted that the selection of motor 610 and control unit in the above description should be selected as needed. This part is well-known technology in the field and will not be elaborated here.

[0026] It should be noted that the hot melt drill bit mentioned above is a chipless machining drill made of tungsten carbide cemented carbide. It is mainly used for drilling and bushing forming of thin metal plates or pipes. It can replace traditional welding or riveting processes and is widely used in industries such as automobiles, aerospace, and stainless steel furniture. This part is well-known technology in the relevant field and will not be elaborated here.

[0027] Working principle: During use, the operator selects a suitable hot melt drill bit and installs it on one end of the robotic arm 4. Then, the operator clamps the front longitudinal beam of the car to be processed using the clamp 604. The operator starts the electric push rod 511 to unfold the protective mechanism 5. After the protective mechanism 5 is fully unfolded, the operator closes the electric push rod 511 and starts the motor 610 and the external control system. The adjusting mechanism 6 clamps the front longitudinal beam of the car and moves along the track direction of the guide rail 2. The slide 3 moves synchronously with the adjusting mechanism 6. The robotic arm 4 controls the position of the hot melt drill bit and drills a hole in the front longitudinal beam of the car. After drilling is completed, the operator reverses the electric push rod 511 to retract the protective mechanism 5. Then, the operator takes out the processed front longitudinal beam of the car.
