[0027] The following is combined with Figure 1-6 , an embodiment of the utility model for an automatic feeding drilling device for an annealing furnace track is further described in detail.

[0028] An automatic feeding drilling device for annealing furnace rail 1, such as Figure 1 , 2As shown, it includes a traveling mechanism 2 that moves linearly along the annealing furnace track 1, a multi-axis linkage control mechanism 3 fixed on the traveling mechanism 2, and a drilling actuator 4 that is movably connected to the multi-axis linkage control mechanism 3. The traveling mechanism 2 includes a moving platform 21, a traveling pulley 22 and a driving wheel assembly 23. The moving platform 21 is a U-shaped structure wrapped around both sides of the annealing furnace track 1 along the width direction, and a magnetic suspension support structure 5 is arranged on one end of the mobile platform 21 that is bent; the traveling pulley 22 is transversely arranged between the moving platform 21 and the annealing furnace track 1, and one end of the traveling pulley 22 is rotatably connected to the moving platform 21, and the other end abuts against the annealing furnace track 1; the driving wheel assembly 23 is transmission-connected to the traveling pulley 22 to drive the traveling mechanism 2 to slide along both sides of the annealing furnace track 1, and drive the multi-axis linkage control mechanism 3 and the drilling actuator 4 to adjust the position of the drilling operation space.

[0029] Specifically, when the walking mechanism 2 is walking on the annealing furnace track, the multi-axis linkage control mechanism 3 simultaneously controls the drilling actuator 4 to perform drilling operations on the annealing furnace track 1, so that a conveying platform for installing a fixture or transporting materials can be equidistantly opened on the annealing furnace track 1; so that when the material is transported into the annealing furnace, the fixture or the conveying platform can move stably and smoothly along the annealing furnace track 1; and the traveling pulley is arranged on the inner side of the mobile platform 21, which is used to slide along the side of the annealing furnace track 1, so as to avoid affecting the drilling work, and at the same time, the walking pulley 22 is driven by the driving wheel assembly 23, which can ensure that the mobile platform 21 always moves and operates following the linear shape of the annealing furnace track 1, and the mobile platform 21 is arranged in a U-shaped structure to prevent the problem of offset during the sliding process.

[0030] Among them, in order to further facilitate the real-time monitoring, fault diagnosis and optimization control of the entire drilling process, a central control mechanism can be set up for control. The central control mechanism adopts the principle of single-chip microcomputer for control, and is based on advanced microprocessors and algorithms. By receiving data from the positioning sensor system and the multi-axis linkage control mechanism 3, real-time processing and analysis are performed, and control instructions are issued according to the processing results to control the operation of the entire device; at the same time, the central control mechanism has self-learning ability, and can optimize drilling parameters according to historical data to improve drilling efficiency and quality.

[0031] In this embodiment, if Figure 6As shown, the magnetic levitation support structure 5 includes a support frame 51 and an electromagnetic induction component 52. The support frame 51 is fixedly connected to the mobile platform 21, and a plurality of mounting holes 511 for mounting the electromagnetic induction component 52 are evenly opened on the support frame 51. The electromagnetic induction component 52 is embedded in the mounting hole 511, and the electromagnetic induction component 52 includes an electromagnetic coil 521, an electromagnet 522 and a barrier strip 523. The electromagnetic coil 521 is magnetically connected to the electromagnet 522, and the barrier strip 523 is spaced between the electromagnets 522.

[0032] Specifically, when the drilling actuator 4 performs the drilling operation, the mobile platform 21 slides along the annealing furnace track 1. At the same time, due to the effect of the magnetic suspension support structure 5, the friction between the mobile platform 21 and the annealing furnace track 1 can be reduced, thereby improving the moving efficiency. Among them, the support frame 51 of the magnetic suspension support structure 5 adopts the electromagnetic induction principle, and generates a magnetic field cutting effect by electromagnetic induction. Then, the magnetic force generated between the cut magnetic fields can overcome its own gravity and generate an upward supporting force, thereby generating a friction force between the mobile platform 21 and the annealing furnace track 1. A certain distance is generated, and the electromagnetic coil 521 generates an electromagnetic field after being energized, and then the electromagnet 522 and the electromagnetic coil 521 have opposite repulsive forces, and the barrier strip 523 can effectively prevent the electromagnets 522 from being attracted to each other. A card slot is provided at one end of the support frame 51 facing the annealing furnace track 1, and the electromagnet 522 is snapped into the card slot. The magnetic force generated by the electromagnet 522 repels the annealing furnace track 1, thereby lifting the mobile platform 21 to a certain height, thereby reducing the friction between the walking mechanism 2 and the annealing furnace track 1, and improving the walking speed of the walking mechanism 2.

[0033] In this embodiment, if Figure 5 As shown, a clamping assembly 6 for pressing against the annealing furnace rail 1 when the drilling actuator 4 is drilling is movably connected to the mobile platform 21, and the clamping assembly 6 is flippably arranged at the bottom of the mobile platform 21; the clamping assembly 6 includes a clamping plate 61, a clamping motor 62 and a hinge 63, the clamping motor 62 is fixed to the top of the mobile platform 21, and the output end of the clamping motor 62 passes through the mobile platform 21 and is transmission-connected to the hinge 63; the hinge 63 is hinged to the clamping plate 61, so that the clamping plate 61 can be flipped and folded 90 degrees.

[0034] Specifically, the clamping assembly 6 can fix the traveling mechanism 2 when the drilling actuator 4 is drilling, thereby preventing deviations from occurring during the drilling operation and affecting the drilling accuracy; and during fixed clamping, the hinge 63 is controlled to flip by the clamping motor 62, and at the same time, the clamping plate 61 folded at the bottom of the mobile platform 21 begins to flip and abuts against the annealing furnace track 1, thereby braking the traveling mechanism 2 at a preset position to prevent the drilling mechanism from being affected by vibrations during drilling and causing drilling deviations.

[0035] In this embodiment, the multi-axis linkage control mechanism 3 includes an X-axis translation component 31, a Y-axis translation component 32 and a Z-axis lifting component 33. The X-axis translation component 31 and the Y-axis translation component 32 are vertically arranged, and the Z-axis lifting component 33 is axially connected to the Y-axis translation component 32. The X-axis translation component 31, the Y-axis translation component 32 and the Z-axis lifting component 33 are slidably connected to each other to form a closed-loop feedback system. The multi-axis linkage control mechanism 3 realizes real-time adjustment of the position of the drill bit 42 through the closed-loop feedback system.

[0036] In order to satisfy the requirement that the drilling actuator 4 has a larger operating space when drilling, the X-axis translation assembly 31, the Y-axis translation assembly 32 and the Z-axis lifting assembly 33 are used to control the movement of the drilling actuator 4 in the multi-axis space, wherein the X-axis translation assembly 31, the Y-axis translation assembly 32 and the Z-axis lifting assembly 33 are all driven by a screw drive, including but not limited to a bidirectional linear guide rail, a guide sleeve, a threaded screw and a servo motor, and a transverse frame is set at the bottom of the X-axis translation assembly 31 for fixing, and a linear slide is connected between the two X-axis translation assemblies 31 for connection, and the linear slide is slidably connected to the X The X-axis translation assembly 31 is on the Y-axis translation assembly 31, the Y-axis translation assembly 32 is arranged on the top and side wall of the linear slide, and the Z-axis lifting assembly 33 is slidably connected to the Y-axis translation assembly 32, so that when the drilling mechanism positions and punches the annealing furnace track 1, the servo motor and the precision transmission mechanism can realize the precise positioning and directional movement of the drill bit 42 in the multi-dimensional space; at the same time, the closed-loop feedback system composed of the X-axis translation assembly 31, the Y-axis translation assembly 32 and the Z-axis lifting assembly 33 can monitor the position and posture of the drill bit 42 in real time, so as to accurately control it according to the preset drilling path to ensure that the drill bit 42 moves according to the predetermined trajectory.

[0037] In this embodiment, if Figure 4 As shown, the drilling actuator 4 includes a machine base 41, a drill bit 42 detachably connected to the machine base 41, and a driving motor 43 for driving the drill bit 42 to rotate. One side of the machine base 41 is slidably connected to the Z-axis lifting assembly 33, one end of the drill bit 42 is inserted into the machine base 41, and the drill bit 42 and the driving motor 43 are connected through a pulley transmission; the drilling actuator 4 is also equipped with an intelligent tool replacement system, which automatically selects and replaces a suitable drill bit 42 according to the drilling task to meet different processing requirements.

[0038] Specifically, the machine base 41 can be lifted up and down along the Z-axis lifting assembly 33. When processing, the pulley is driven by the driving motor 43 to rotate, thereby driving the drill bit 42 to rotate and drill. At the same time, the drilling actuator 4 integrates high-performance drilling tools and intelligent power management systems, which can automatically adjust the speed and feed rate of the drilling tool according to the drilling parameters to adapt to different processing requirements. At the same time, the intelligent power management system can monitor the power consumption and torque changes during the drilling process in real time to ensure the stability of the drilling process, thereby achieving an efficient and stable drilling process.

[0039] It is worth noting that an intelligent tool replacement system is also provided on the drilling actuator 4, which is convenient for quickly and automatically selecting and replacing a suitable drill bit 42 when processing holes of different aperture sizes to adapt to different processing requirements. The intelligent tool replacement system is a common and well-known technology in the prior art, and its tool replacement principle will not be repeated here.

[0040] In order to improve the accuracy of the drilling position, the drilling actuator 4 is also equipped with a positioning sensor system, which adopts lidar sensing technology. The positioning sensor system adopts laser interferometry measurement technology, combined with image recognition algorithm, to achieve sub-micron positioning of the drilling position; the positioning sensor system captures the geometric information of the annealing furnace track 11 through a high-precision laser sensor, and uses advanced image processing technology to analyze the collected image data, so as to accurately calculate the drilling position.

[0041] The working principle of this utility model:

[0042] Before use, the operator sets drilling parameters, such as drilling position, drilling depth, drilling speed, etc., through the user interface of the central control mechanism, and then the central control mechanism generates control instructions according to the set parameters and sends them to the corresponding execution unit; after starting the device, the mobile platform 21 slides along the annealing furnace track 1 to the preset drilling position according to the instructions of the central control mechanism, and the clamping assembly 6 flips to fix and clamp the annealing furnace track 1, and at the same time, the positioning sensor system starts to work, and accurately measures and locates the drilling position through laser interferometry technology and image recognition algorithm; once the positioning is completed, the multi-axis linkage control mechanism controls the drill bit 42 to move to the specified position according to the instructions of the central processing unit; the drilling actuator 4 automatically adjusts the speed and feed rate of the drill bit 42 according to the drilling parameters, and starts the drilling process; after the drilling is completed, the drilling actuator 4 stops working, the multi-axis linkage control mechanism 3 moves the drill bit 42 back to the initial position, and the mobile platform 21 also returns to the starting point. The entire drilling process does not require manual intervention, and automatic operation is realized.

[0043] The utility model discloses an automatic feeding drilling device for the annealing furnace rail 1, which realizes efficient and accurate drilling of the annealing furnace rail 1 by integrating an advanced positioning system, a walking mechanism 2, a multi-axis linkage control mechanism 3, and a drilling actuator 4.
