Description

Technical Field

[0001] The present invention belongs to the technical field of cutting equipment. Specifically, it particularly relates to an automatic feeding track saw and its automatic feeding method. Background Art

[0002] A track saw is a common cutting tool, often used for cutting materials such as wood and metal. During the cutting process of existing track saws, usually, an operator needs to manually push the saw body along the track to achieve the feeding of cutting. For example, the patent with the publication number "CN221754893U" discloses a track saw that performs cutting by manual feeding. However, manual feeding has the following problems: 1. It is difficult for the operator to maintain consistent force and speed, which easily leads to an uneven cutting surface and affects the cutting quality. In some occasions with high requirements for cutting accuracy, manual feeding is difficult to meet the accuracy requirements; 2. Manual operation has a high labor intensity.

[0003] The patent with the publication number "CN215145237U" discloses a sawing device with direct gear drive for active walking, including a vehicle frame arranged on the track, a sawing mechanism and a moving mechanism arranged on the vehicle frame; the moving mechanism includes a moving reduction gear and an active wheel assembly; the active wheel assembly includes an active shaft and an active gear, the active shaft is rotatably connected to the vehicle frame; the active gear is connected to the moving reduction gear, the active gear is arranged on the active shaft and meshes with a rack arranged on the track to drive the vehicle frame to move on the track. This sawing device adopts a transmission method of active gear drive for walking, making the sawing device operate stably, accurately, and improving the transmission efficiency.

[0004] Although the above patents solve the problem of the automatic forward movement of the sawing device, they belong to large-scale equipment with a single working environment, cannot be carried and transported portably, and at the same time, do not have the function of switching between manual pushing and automatic feeding at any time and automatically limiting and adjusting the cutting depth. Currently, there is no track saw that can perform automatic feeding and automatically limit the cutting depth. Summary of the Invention

Through a cutting depth limiting mechanism, it realizes automatically limiting the rotation angle of the rotating saw body assembly, without the need for manual pressing down, thereby precisely controlling the cutting depth and ensuring the consistency of the cutting quality. At the same time, in cooperation with the automatic feeding mechanism, it does not require manual pushing and realizes automated sawing operations, greatly improving the work efficiency and sawing accuracy.

[0006] The described automatic feeding track saw includes a track saw body, which consists of a base and a rotating saw body assembly. One end of the rotating saw body assembly is rotatably connected to the base. An automatic feeding mechanism for driving the track saw body to move forward along the guide rail is provided on the base. At the other end of the base near the rotating saw body assembly, a cutting depth limiting mechanism for limiting the rotation angle of the rotating saw body assembly is fixedly connected. An obstacle avoidance component is provided on the base, which can sense an obstacle and control the automatic feeding mechanism to stop.

[0007] Preferably, the automatic feeding mechanism includes a first fixed seat. A feeding power mechanism is fixedly connected to the first fixed seat. The output end of the feeding power mechanism is fixedly connected with a feeding gear. A feeding rack meshing with the feeding gear is fixedly connected to the guide rail. The output end of the feeding power mechanism penetrates through the first fixed seat and is fixedly connected with a mounting disc. A limiting platform slidably matched with the end face of the feeding rack is fixedly connected to the mounting disc. The feeding gear is fixedly installed at the end of the mounting disc.

[0008] Preferably, the obstacle avoidance component includes a swinging seat and a second limit switch. An elastic component two is provided between the swinging seat and the second limit switch. A mounting plate is fixedly connected to the first fixed seat. The swinging seat is rotatably connected to the mounting plate.

[0009] Preferably, a first limit switch for sensing the guide rail is fixedly connected to the bottom of the first fixed seat. The first limit switch is connected to the feeding power mechanism. A damper is fixedly connected to the front end of the rotating saw body assembly. The moving end of the damper is matched with the first fixed seat.

[0010] Preferably, the obstacle avoidance component is a proximity switch.

[0011] Preferably, a feeding speed regulation button and a feeding switch are provided on the rotating saw body assembly. The feeding speed regulation button and the feeding switch are respectively connected to the automatic feeding mechanism.

[0012] Preferably, a sawing power mechanism and a sawing mechanism are fixedly connected to the rotating saw body assembly. The sawing mechanism includes a protective cover. A saw blade is provided inside the protective cover. The saw blade is fixedly connected to the output end of the sawing power mechanism. A dust suction pipe is communicated with the protective cover.

[0013] Preferably, the cutting depth limiting mechanism includes a second fixed seat. The second fixed seat is fixedly connected to the base. A steering gear is fixedly connected to the second fixed seat. The output end of the steering gear is fixedly connected with an elastic hook. A cutting depth limit switch for starting the steering gear is provided on the base. A cutting depth limit rack engaged with the elastic hook is fixedly connected to the rotating saw body assembly. A cutting depth limit contact rod that can be adjusted and matched with the cutting depth limit switch is provided on the rotating saw body assembly.

[0014] Preferably, a cutting depth adjuster corresponding to the cutting depth limit contact rod is provided on the base. The cutting depth adjuster includes an auxiliary support ruler, the bottom of the auxiliary support ruler is fixedly connected to the base, a cutting depth adjustment slider is slidably connected to the auxiliary support ruler, an auxiliary elastic sheet matched with the auxiliary support ruler is fixedly connected inside the cutting depth adjustment slider, tooth-shaped structures are respectively arranged on the auxiliary elastic sheet and the auxiliary support ruler, and a limit bolt for fixing the auxiliary elastic sheet is threadedly connected to the cutting depth adjustment slider; the cutting depth limit switch is installed on the top of the cutting depth adjustment slider.

[0015] The automatic feeding method uses the above-mentioned automatic feeding track saw and includes the following steps: S1. Place the plate to be cut at the bottom of the guide rail, adjust the cutting depth of the rotating saw body assembly according to the thickness of the plate, and synchronously adjust the heights of the cutting depth adjustment slider and the cutting depth limit contact rod according to the cutting depth, so that when the rotating saw body assembly is pressed down to a proper position, the cutting depth limit contact rod can contact the cutting depth limit switch; S2. Press down the rotating saw body assembly, the rotating saw body assembly rotates relative to the base, and the cutting depth limit rack descends accordingly. When the rotating saw body assembly is pressed down in place, the cutting depth limit contact rod contacts the cutting depth limit switch, and the cutting depth limit switch starts the servo motor. The servo motor drives the elastic hook to rotate, so that the elastic hook is stuck in the tooth groove of the corresponding cutting depth limit rack to complete the positioning of the rotating saw body assembly; S3. When automatic cutting is required, start the automatic feeding mechanism and the sawing power mechanism. The automatic feeding mechanism drives the track saw body to automatically advance along the guide rail. At the same time, the sawing power mechanism drives the saw blade to automatically cut the plate; S4. When manual cutting is required, turn off the automatic feeding mechanism and manually push the track saw body forward for cutting; S5. When an obstacle is encountered ahead, after the obstacle avoidance component senses the obstacle, it controls the sawing power mechanism and the automatic feeding mechanism to stop. At the same time, the servo motor starts, so that the elastic hook disengages from the cutting depth limit rack, and the rotating saw body assembly reversely rotates and resets.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. A cutting depth limit mechanism and an automatic feeding mechanism are added. In the prior art, the cutting depth is mainly limited by manual real-time pressing down, resulting in poor sawing accuracy. Through the cutting depth limit mechanism, the rotation angle of the rotating saw body assembly is automatically limited, and manual pressing down is not required, so as to accurately control the cutting depth, ensure the consistency of sawing quality. At the same time, in cooperation with the automatic feeding mechanism, manual pushing is not required, and automatic sawing operation is realized, greatly improving the working efficiency and sawing accuracy.

[0017] 2. The cutting depth limit mechanism accurately limits the rotation angle of the rotating saw body assembly. In cooperation with the cutting depth limit contact rod and the cutting depth limit switch, it can accurately adjust the cutting depth according to the thickness of the board, adapt to the cutting of boards with different thicknesses, and has a wide range of application scenarios. At the same time, it ensures the stability of cutting accuracy and quality.

[0018] 3. An obstacle avoidance component is added. During the automatic feeding and cutting process, the obstacle avoidance component can sense obstacles in a timely manner, control the cutting and feeding mechanisms to stop, and the servo motor also makes the rotating saw body assembly reverse and reset, preventing collision damage to the equipment and ensuring the safety of operators.

[0019] 4. The rotating saw body assembly is provided with a feeding speed adjustment button and a feeding switch, which can flexibly adjust the feeding speed as needed, start and stop the automatic feeding, and can also freely switch between automatic and manual cutting, meeting diverse cutting requirements and improving the operation convenience and efficiency.

Specific implementation mode

[0022] The present invention will be further described below with reference to the accompanying drawings: In the paragraphs of detailed description, the orientation nouns involved are only for the convenience of those skilled in the art to understand the technical solutions recorded in the present application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "set", "install", "connect", etc. should be understood in a broad sense. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] Embodiment 1: As Figures 1 to 17As shown, an automatic feeding track saw includes a track saw body 1, which is the core component of the sawing operation. During the sawing process, the entire track saw body 1 moves forward along the guide rail 2. The track saw body 1 includes a base 105 and a rotating saw body assembly. One end of the rotating saw body assembly is rotatably connected to the base 105, that is, the rotating saw body assembly can be flexibly rotated relative to the base 105. When cutting plates of different thicknesses, the sawing depth of the saw blade can be adjusted by adjusting the rotation angle of the rotating saw body assembly, thereby adapting to different sawing requirements.

[0024] like Figure 11 As shown, the base 105 is provided with an automatic feeding mechanism 4 for driving the track saw body 1 to move forward along the guide rail 2. Driving the automatic feeding mechanism 4 can make the track saw body 1 automatically move forward along the guide rail 2 without manual pushing, thereby realizing automated sawing operation, greatly improving work efficiency and sawing accuracy. The other end of the base 105 close to the rotating saw body assembly is fixedly connected with a cutting depth limiting mechanism 5 for limiting the rotation angle of the rotating saw body assembly. In the prior art, the sawing depth is mainly limited by manual real-time downward pressure, resulting in poor sawing accuracy, while the cutting depth limiting mechanism 5 can automatically limit the rotation angle of the rotating saw body assembly, thereby accurately controlling the sawing depth, ensuring the consistency of sawing quality, and providing conditions for automatic sawing. The base 105 is provided with an obstacle avoidance component for sensing an obstacle and controlling the automatic feeding mechanism 4 to stop. The obstacle avoidance component realizes automatic shutdown, avoids the saw blade from accidentally cutting an obstacle, causing damage to the saw blade and accidentally injuring the obstacle, and greatly improves the safety of automatic sawing.

[0025] like Figures 2 to 5 As shown, the automatic feeding mechanism 4 includes a fixed seat 411, which serves as the installation base of the entire automatic feeding mechanism 4 and provides stable support for other components. The base 105 is fixedly connected with a rotating support seat 7, which is rotatably connected to the rotating saw body assembly through an axis. During installation, the fixed seat 411 is fixedly connected to the rotating support seat 7, which makes the structure of the present invention more compact without hindering the structure and rotation of the rotating saw body assembly.

[0026] A feed power mechanism 402 is fixedly connected to a fixed seat 411, and a protective cover 401 is provided outside the feed power mechanism 402. The protective cover 401 is used to protect the feed power mechanism 402. The feed power mechanism 402 is preferably a DC reduction motor, and the DC reduction motor is connected to the adjustable transformer in the track saw body 1. The feed power mechanism 402 has a compact structure and a stable and strong power output. By adjusting the rotation speed and torque of the feed power mechanism 402, it can be precisely adjusted according to different sawing requirements to adapt to different working scenarios.

[0027] The output end of the feeding power mechanism 402 penetrates through the first fixed seat 411 and is fixedly connected with a mounting plate 403. A limiting platform 404 that is slidably matched with the end face of the feeding rack 3 is fixedly connected to the mounting plate 403, and a feeding gear 405 is fixedly connected to the end of the mounting plate 403. The limiting platform 404 plays a role in limiting and guiding, preventing the feeding gear 405 from shifting during transmission, and ensuring the stability and accuracy of transmission. A feeding rack 3 that meshes with the feeding gear 405 is fixedly connected to the guide rail 2. Through the transmission mode of gear and rack, the rotational motion of the feeding power mechanism 402 is converted into the linear motion of the track saw body 1, achieving precise feeding control, and having the advantages of high transmission efficiency and high precision.

[0028] In addition, the automatic feeding mechanism 4 can also be directly driven by a linear motor. In this embodiment, the obstacle avoidance assembly includes a swing seat 408 and a second limit switch 410. An elastic assembly II 409 is provided between the swing seat 408 and the second limit switch 410. The elastic assembly II 409 is preferably a metal elastic sheet. A mounting plate 406 is fixedly connected to the first fixed seat 411. The mounting plate 406 is used to mount the swing seat 408 and the first shield 401. The first shield 401 is fixedly connected to the mounting plate 406 through fasteners. The upper part of the swing seat 408 is rotatably connected to the mounting plate 406 through a pin shaft. One end of the swing seat 408 abuts against the elastic assembly II 409, and the other end of the swing seat 408 abuts against the end face of the first fixed seat 411, thereby limiting the swing seat 408 to only rotate towards the side of the elastic assembly II 409. During use, when there is an obstacle ahead, as the track saw body 1 advances, the swing seat 408 contacts the obstacle, and the obstacle will push the swing seat 408 to swing, compressing the elastic assembly II 409. The elastic assembly II 409 contacts the second limit switch 410, triggering the second limit switch 410, thereby controlling the feeding power mechanism 402 to stop, avoiding equipment damage.

[0029] To further improve the sawing safety, in this embodiment, the second limit switch 410 simultaneously controls the servo motor 504 in the sawing power mechanism 106 and the depth limit mechanism 5, causing the sawing power mechanism 106 to stop, and the saw blade no longer rotates. At the same time, the servo motor 504 reverses, causing the depth limit mechanism 5 to no longer limit the rotating saw body assembly.

[0030] In addition, the obstacle avoidance assembly can also use a proximity switch instead of the above solution. The proximity switch can detect the presence of an obstacle without contacting the obstacle. When the proximity switch detects an obstacle ahead, it will quickly send a signal to control the sawing power mechanism 106 and the automatic feeding mechanism 4 to stop, improving the timeliness and accuracy of obstacle avoidance.

[0031] Such as Figure 3As shown, a limit switch 407 for sensing the guide rail 2 is fixedly connected to the bottom of the fixed seat 411. The limit switch 407 is connected to the feed power mechanism 402. That is, during the sawing process, the limit switch 407 always senses the guide rail 2. When the track saw body 1 is lifted or the track saw body 1 moves to the end of the guide rail 2, that is, when the track saw body 1 is separated from the guide rail 2, the limit switch 407 will immediately detect it and transmit a signal to the feed power mechanism 402 to make it stop working, ensuring the safe operation of the equipment.

[0032] As Figure 2 shown, the rotating saw body assembly is provided with a feed speed control button 101 and a feed switch 102. The feed speed control button 101 and the feed switch 102 are respectively connected to the automatic feed mechanism 4. The operator can control the feed speed control button 101 according to the actual sawing situation to adjust the feed speed of the track saw body 1. By controlling the feed switch 102, the start and stop of the automatic feed mechanism 4 can be controlled, and automatic or manual sawing can be selectively performed, which is convenient and fast to operate.

[0033] As Figure 2 and Figure 9 shown, a sawing power mechanism 106 and a sawing mechanism 9 are fixedly connected to the rotating saw body assembly. The sawing power mechanism 106 usually adopts a high-speed motor and can drive the saw blade 901 to rotate at a high speed to achieve efficient sawing operations. The sawing mechanism 9 includes a protective cover 902. A saw blade 901 is arranged inside the protective cover 902. The saw blade 901 is fixedly connected to the output end of the sawing power mechanism 106. A dust suction pipe 903 is communicated with the protective cover 902. The protective cover 902 can not only protect the safety of the operator and prevent the saw blade from splashing and hurting people, but also reduce the diffusion of dust generated during the sawing process. A dust suction pipe 903 is communicated with the protective cover 902, and the dust suction pipe 903 can be connected to a dust suction device to timely suck away the dust generated during the sawing process and improve the working environment.

[0034] As Figures 6 to 8 shown, the cutting depth limiting mechanism 5 includes a fixed seat 502. The fixed seat 502 is fixedly connected to the base 105. The fixed seat 502 is the support foundation of the entire cutting depth limiting mechanism 5. A steering gear 504 is fixedly connected to the fixed seat 502. The output end of the steering gear 504 is fixedly connected to an elastic hook 503. The elastic hook 503 includes a central disk 5031. An arc-shaped elastic piece 5032 is fixedly connected to the central disk 5031. A hook 5033 is fixed at the end of the arc-shaped elastic piece 5032. The hook 5033 cooperates with the cutting depth limiting rack 6. This structure makes the elastic hook 503 have a certain elasticity and flexibility and can better cooperate with the cutting depth limiting rack 6.

[0035] A second fixing base 502 is provided with a second protective cover 501 on the outside. The second fixing base 502, the steering gear 504, and the elastic hook 503 are all arranged inside the second protective cover 501. The second protective cover 501 is fixedly connected to the bottom. The second protective cover 501 is provided with slots matching the elastic hook 503 and the cutting depth limit rack 6. The second protective cover 501 is used to protect the cutting depth limiting mechanism 5 and the cutting depth limit rack 6.

[0036] A cutting depth limit switch 104 for starting the steering gear 504 is provided on the base 105. A cutting depth limit rack 6 that is fixedly connected to the rotating saw body assembly and is in snap-fit with the elastic hook 503 is provided. A cutting depth limit contact rod 103 that can be adjusted and matches the cutting depth limit switch 104 is provided on the rotating saw body assembly. As Figure 9 shown, an arc-shaped guide post 109 and a cutting depth scale 110 are fixed on the base 105. The cutting depth scale 110 is also an arc-shaped structure, and the upper end of the cutting depth scale 110 is fixedly connected to the arc-shaped guide post 109. A guide seat 108 is fixed on the rotating saw body assembly. The cutting depth scale 110 and the arc-shaped guide post 109 both penetrate through the guide seat 108 and are in sliding fit with the guide seat 108. An elastic component 111 is sleeved on the arc-shaped guide post 109. The elastic component 111 is a spring. The upper end of the elastic component 111 abuts against the bottom of the guide seat 108, and the lower end of the elastic component 111 abuts against the lower part of the arc-shaped guide post 109. The elastic component 111 enables the rotating saw body assembly to automatically form a certain angle with the base 105 without limitation and external force, so that the saw blade does not contact the board, forming Figure 8 the structure shown.

[0037] A cutting depth limit block 8 is slidably connected to the cutting depth scale 110. The cutting depth limit block 8 is used to preset the cutting depth. An adjusting bolt 801 that matches the cutting depth scale 110 is threadedly connected to the cutting depth limit block 8. By loosening the adjusting bolt 801, the position of the cutting depth limit block 8 can be adjusted, and then by tightening the adjusting bolt 801, the cutting depth limit block 8 is positioned to complete the presetting of the cutting depth. A cutting depth adjusting rod 1081 is threadedly connected to the guide seat 108. The cutting depth adjusting rod 1081 cooperates with the cutting depth limit block 8. By adjusting the length of the cutting depth adjusting rod 1081, the cutting depth can be further finely adjusted, which is convenient for fine processing such as grooving and ensures the accuracy of the cutting depth. During operation, when the rotating saw body assembly presses down, the cutting depth adjusting rod 1081 abuts against the cutting depth limit block 8 to determine the actual cutting depth.

[0038] The cutting depth limiting contact rod 103 is used in conjunction with the cutting depth adjusting rod 1081. After determining the actual cutting depth, the length of the cutting depth limiting contact rod 103 is adjusted synchronously so that when the cutting depth adjusting rod 1081 abuts against the cutting depth limiting block 8, the cutting depth limiting contact rod 103 can also contact the cutting depth limiting switch 104. During operation, the operator adjusts the heights of the cutting depth limiting block 8, the cutting depth adjusting rod 1081, and the cutting depth limiting contact rod 103 according to the thickness of the plate. When the rotating saw body assembly is pressed down to the appropriate position, the cutting depth limiting contact rod 103 contacts the cutting depth limiting switch 104, triggering the servo 504 to work, so that the elastic hook 503 is stuck in the tooth groove of the corresponding cutting depth limiting rack 6, completing the positioning of the rotating saw body assembly.

[0039] Embodiment 2: As Figures 15 to 17 shown, for an automatically feeding track saw, a damper 10 is fixedly connected to the front end of the rotating saw body assembly, that is, the end close to the rotating support seat 7. The damper 10 is a prior art and is commercially available. The moving end of the damper 10 is matched with the first fixed seat 411. During use, the moving end of the damper 10 contacts the first fixed seat 411. When pressing down the rotating saw body assembly, the moving end of the damper 10 extends and abuts against the first fixed seat 411, so that during sawing of the track saw, the damper 10 can absorb and consume the vibration energy during sawing, reduce the shaking of the saw body, reduce the noise generated by vibration, protect the internal components of the track saw, extend the service life of the equipment, and at the same time can also avoid the decrease in cutting accuracy caused by vibration.

[0040] When the rotating saw body assembly completes pressing down for cutting and lifting and resetting, the damper 10 can limit its rotating speed, making its movement smoother and more controllable. It avoids the out-of-control operation caused by the rapid rotation and reset of the rotating saw body assembly, prevents violent shaking caused by inertia, improves the operation safety, and ensures the smoothness of the cutting process and the cutting quality. In addition, the damper 10 cooperates with the cutting depth limiting mechanism 5. After the rotating saw body assembly is pressed down in place, the damper 10 can provide a certain resistance to keep the saw body in a stable position, enhance the accuracy of positioning, prevent the saw body from displacing due to factors such as force during the cutting process, and ensure the consistency of the cutting depth and the cutting accuracy.

[0041] As Figure 16 and Figure 17As shown in the figure, a cutting depth adjuster 11 corresponding to the cutting depth limit contact rod 103 is provided on the base 105. The cutting depth adjuster 11 cooperates with the cutting depth limit contact rod 103 to more quickly adjust the cutting depth of the saw blade. Specifically, the cutting depth adjuster 11 includes an auxiliary support ruler 1107. The auxiliary support ruler 1107 serves as the framework of the cutting depth adjuster 11, and the bottom of the auxiliary support ruler 1107 is fixedly connected to the base 105 to form a rigid support foundation. A cutting depth adjustment slider 1101 is slidably connected to the auxiliary support ruler 1107. A chute 1103 matching the auxiliary support ruler 1107 is opened in the cutting depth adjustment slider 1101. That is, the auxiliary support ruler 1107 provides an accurate sliding track for the cutting depth adjustment slider 1101, restricting it to move only along the height direction of the auxiliary support ruler 1107 to avoid lateral deviation from interfering with the control of the cutting depth.

[0042] An auxiliary elastic sheet 1106 matching the auxiliary support ruler 1107 is fixedly connected inside the cutting depth adjustment slider 1101. Matching tooth-shaped structures are respectively provided on the auxiliary elastic sheet 1106 and the auxiliary support ruler 1107, and a reliable positioning and locking system is formed through the matching tooth-shaped structures. When the cutting depth adjustment slider 1101 moves to the target position, the auxiliary elastic sheet 1106 is embedded in the tooth groove of the auxiliary support ruler 1107 under the action of its own elastic force to generate mechanical engagement and temporarily fix the cutting depth adjustment slider 1101. A threaded hole 1102 is opened in the cutting depth adjustment slider 1101, and a limit bolt 1104 for fixing the auxiliary elastic sheet 1106 is threadedly connected in the threaded hole 1102. An elastic component three 1105 is sleeved between the limit bolt 1104 and the cutting depth adjustment slider 1101, and the elastic component three 1105 is preferably a spring. The operator tightens the limit bolt 1104 to apply an additional tightening force. At this time, the elastic component three 1105 is in a compressed state, making the engagement between the auxiliary elastic sheet 1106 and the tooth-shaped structure of the auxiliary support ruler 1107 tighter, improving the positioning reliability, preventing it from displacing due to external forces such as vibration and impact during the operation of the track saw, and ensuring the stability of the cutting depth, especially suitable for long-term and high-load cutting operation scenarios.

[0043] An installation groove 1108 is opened at the top of the cutting depth adjustment slider 1101. The cutting depth limit switch 104 is installed in the installation groove 1108 at the top of the cutting depth adjustment slider 1101. When the rotating saw body assembly presses down, the cutting depth limit contact rod 103 contacts the cutting depth limit switch 104 to realize the starting control of the cutting depth limit mechanism 5. The rest is the same as in the first embodiment.

[0044] Embodiment 3: As Figures 9 to 14 shown, for the automatic feeding method described above, an automatic feeding type track saw in Embodiment 2 is adopted, including the following steps: S1. Preparation. Place the sheet to be cut at the bottom of the guide rail 2, ensure the accurate position of the sheet to avoid movement during sawing. The operator adjusts the cutting depth of the rotating saw body assembly according to the thickness of the sheet to ensure that the sawing depth meets the requirements.

[0045] The cutting depth adjustment method is as follows: 1.1. Loosen the adjustment bolt 801. According to the cutting depth requirement, slide the cutting depth limit block 8 along the cutting depth scale 110 to the corresponding position, align the upper end of the cutting depth limit block 8 with the corresponding cutting depth scale line, and tighten the adjustment bolt 801 to fix the cutting depth limit block 8 at this position to achieve the preset of the cutting depth. 1.2. Rotate the cutting depth adjustment rod 1081 to finely adjust the preset cutting depth to ensure its accuracy. When pressing down the rotating saw body assembly, the cutting depth adjustment rod 1081 abuts against the upper end of the cutting depth limit block 8. 1.3. Adjust the cutting depth regulator 11. Loosen the limit bolt 1104 on the cutting depth adjustment slider 1101. At this time, the auxiliary elastic piece 1106 is released from the tight locking state with the tooth-shaped structure of the auxiliary support scale 1107. The operator can manually push the cutting depth adjustment slider 1101 to slide it along the auxiliary support scale 1107. During the sliding process, the auxiliary elastic piece 1106 jumps between the tooth grooves of the auxiliary support scale 1107 under its own elastic force, providing clear adjustment feedback to help the operator determine the position of the slider. After the slider moves near the preset cutting depth, tighten the limit bolt 1104 to further fasten the auxiliary elastic piece 1106 to make it tightly engage with the tooth-shaped structure of the auxiliary support scale 1107, and complete the position fixation of the cutting depth adjustment slider 1101. 1.4. Rotate the cutting depth limit contact rod 103 to finely adjust the cutting depth limited by the cutting depth regulator 11 so that when the cutting depth adjustment rod 1081 abuts against the upper end of the cutting depth limit block 8, the cutting depth limit contact rod 103 can contact the cutting depth limit switch 104. The cutting depth limit contact rod 103 is used to trigger the cutting depth limit switch 104 on the one hand and play a role of shock absorption and limit on the other hand to prevent the rotating saw body assembly from vibrating or shaking during sawing, which affects the cutting quality.

[0046] S2. Automatic positioning of the rotating saw body assembly. Press down the rotating saw body assembly, and the rotating saw body assembly rotates relative to the base 105. As the rotating saw body assembly rotates, the cutting depth limit rack 6 descends accordingly. When the rotating saw body assembly is pressed down in place, the cutting depth limit contact rod 103 contacts the cutting depth limit switch 104, and the cutting depth limit switch 104 immediately activates the servo motor 504. The servo motor 504 drives the elastic hook 503 to rotate. Due to the certain elasticity and flexibility of the elastic hook 503, the hook 5033 on the elastic hook 503 can smoothly engage with the tooth groove of the corresponding cutting depth limit rack 6, completing the automatic positioning of the rotating saw body assembly. After the rotating saw body assembly is positioned, the accuracy and stability of the cutting depth are ensured, and the cutting quality is improved.

[0047] S3. Automatic cutting. In this embodiment, a handle 107 is provided on the rotating saw body assembly, and a sawing switch is provided on the handle 107. When automatic cutting is required, the operator activates the feeding switch 102, and the feeding switch 102 controls the automatic feeding mechanism 4 to start. At the same time, the operator activates the sawing power mechanism 106 through the sawing switch. The feeding power mechanism 402 in the automatic feeding mechanism 4 drives the feeding gear 405 to rotate. The feeding gear 405 meshes with the feeding rack 3, driving the track saw body 1 to automatically advance along the guide rail 2. At the same time, the sawing power mechanism 106 drives the saw blade 901 to rotate at high speed to automatically cut the board. During the cutting process, the operator can adjust the feeding speed of the track saw body 1 according to the actual situation through the feeding speed adjustment button 101 to ensure the cutting effect.

[0048] S4. Manual cutting. When encountering some special situations, such as fine-tuning the cutting accuracy or when manual cutting is required due to a malfunction of the equipment's automatic feeding, the operator can turn off the automatic feeding mechanism 4 and cut by manually pushing the track saw body 1 forward. Manual cutting can rely on the operator's operation experience and skills to better handle some complex cutting requirements.

[0049] S5. Obstacle avoidance processing. When an obstacle is encountered ahead, the obstacle avoidance component will immediately come into play. Whether the swing seat 408 triggers the limit switch two 410 or an obstacle is detected by the proximity switch, the sawing power mechanism 106 and the automatic feeding mechanism 4 will be quickly controlled to stop, preventing the equipment from colliding with the obstacle and being damaged. At the same time, the servo motor 504 is activated to drive the elastic hook 503 to rotate, disengaging it from the cutting depth limit rack 6. At this time, the damper 10 plays a buffering role, causing the rotating saw body assembly to slowly reverse and reset, avoiding inertial vibration and preparing for the next cutting. The obstacle avoidance processing mechanism improves the safety and reliability of the equipment and reduces the damage rate of the equipment.

[0050] Finally, although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
