Description

Technical Field

[0001] The present invention belongs to the technical field of cutting equipment, and more particularly, to an automatic feeding track saw and an automatic feeding method thereof. 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, it is usually necessary for an operator to manually push the saw body along the track to achieve the feeding of cutting. For example, a 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] A patent with the publication number "CN215145237U" discloses a sawing device with gear direct drive for active walking, including a vehicle frame arranged on a 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 gear active 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 are large-scale equipment with a single working environment, unable to be carried and transported portably. At the same time, they 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

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an automatic feeding track saw and an automatic feeding method thereof. Through a cutting depth limiting mechanism, it realizes the automatic limitation of the rotation angle of the rotating saw body assembly, without the need for manual pressing, thereby accurately 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.

[0008] Preferably, 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.

[0009] 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.

[0010] 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.

[0011] Preferably, the obstacle avoidance component is a proximity switch.

[0012] 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.

[0013] 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.

[0014] Preferably, the cutting depth limiting mechanism includes a second fixed seat. The second fixed seat is fixedly connected to the base. A steering engine is fixedly connected to the second fixed seat. The output end of the steering engine is fixedly connected with an elastic hook. A cutting depth limit switch for starting the steering engine 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 capable of being adjusted and matched with the cutting depth limit switch is provided on the rotating saw body assembly.

[0015] The described automatic feeding method uses the above 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 height of the cutting depth limit contact rod according to the cutting depth, so that when the rotating saw body assembly is pressed down to the appropriate 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 drops 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, completing 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 move forward automatically 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 rotates in reverse to reset.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The cutting depth limit mechanism and the 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 there is no need for manual pressing down, 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, there is no need for manual pushing, realizing automatic sawing operation, greatly improving work 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, the sawing depth is accurately adjusted according to the thickness of the plate, adapting to the cutting of plates with different thicknesses, and having a wide range of application scenarios. At the same time, the stability of cutting accuracy and quality is ensured.

[0018] 3. The obstacle avoidance component is added. During the automatic feeding and sawing process, the obstacle avoidance component can sense obstacles in time, control the sawing and feeding mechanisms to stop, and the servo motor also makes the rotating saw body assembly rotate in reverse to reset, preventing collision and 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.

[0022] The present invention will be further described below with reference to the accompanying drawings: In the paragraphs of the detailed description, the orientation nouns involved are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, terms such as "set", "installed", "connected", 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 specific situations.

[0023] As Figures 1 to 14 As shown, an automatic feed track saw includes a track saw body 1. The track saw body 1 is the core component for sawing operations. During the sawing process, the entire track saw body 1 will move 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 rotate flexibly 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, so as to adapt to different sawing requirements.

[0024] As Figure 11 As shown, an automatic feed mechanism 4 for driving the track saw body 1 to move forward along the guide rail 2 is provided on the base 105. Driving the automatic feed mechanism 4 can make the track saw body 1 automatically move forward along the guide rail 2 without manual pushing, realizing an 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 depth cutting limit 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 pressing down, resulting in poor sawing accuracy. However, the depth cutting limit mechanism 5 realizes automatic limitation of the rotation angle of the rotating saw body assembly, thereby accurately controlling the sawing depth, ensuring the consistency of sawing quality, and at the same time providing conditions for automatic sawing. An obstacle avoidance component for sensing an obstacle and controlling the automatic feed mechanism 4 to stop is provided on the base 105. The obstacle avoidance component realizes automatic shutdown, avoiding the saw blade from accidentally cutting an obstacle, resulting in damage to the saw blade and accidental injury to the obstacle, greatly improving the safety of automatic sawing.

[0025] As Figures 2 to 5As 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 feed power mechanism 402 passes through the fixed seat 411 and is fixedly connected to the mounting plate 403, to which is fixedly connected a limit table 404 that slides with the end face of the feed rack 3, and to which is fixedly connected a feed gear 405. The limit table 404 plays a role of limiting and guiding, preventing the feed gear 405 from deviating during the transmission process, thereby ensuring the stability and accuracy of the transmission. The guide rail 2 is fixedly connected to a feed rack 3 that meshes with the feed gear 405. Through the transmission method of the gear rack, the rotational motion of the feed power mechanism 402 is converted into the linear motion of the track saw body 1, thereby achieving precise feed 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 409 is provided between the swing seat 408 and the second limit switch 410. The elastic assembly 409 is preferably a metal shrapnel. 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 rotationally connected to the mounting plate 406 through a pin shaft. One end of the swing seat 408 abuts against the elastic assembly 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 rotate only towards the side of the elastic assembly 409. During use, when there is an obstacle in front, as the track saw body 1 advances, the swing seat 408 contacts the obstacle. The obstacle will push the swing seat 408 to swing, compressing the elastic assembly 409. The elastic assembly 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 sawing power mechanism 106 and the servo motor 504 in the cutting 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 rotates in reverse, causing the cutting 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 in front, 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] As Figure 3 shown, a first limit switch 407 for sensing the guide rail 2 is fixedly connected to the bottom of the first fixed seat 411. The first limit switch 407 is connected to the feeding power mechanism 402. That is, during sawing, the first 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 first limit switch 407 will immediately detect it and transmit a signal to the feeding power mechanism 402 to make it stop working, ensuring the safe operation of the equipment.

[0032] As Figure 2As shown, the rotating saw body assembly is provided with a feed speed control button 101 and a feed switch 102, and 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, with convenient and fast operation.

[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, which 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, and 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 flying 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 suck away the dust generated during the sawing process in time and improve the working environment.

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

[0035] A second protective cover 501 is arranged outside the second fixed seat 502. The second fixed seat 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. Slots matching the elastic hook 503 and the cutting depth limiting rack 6 are opened on the second protective cover 501. The second protective cover 501 is used to protect the cutting depth limiting mechanism 5 and the cutting depth limiting rack 6.

[0036] A cutting depth limiting switch 104 for starting the steering gear 504 is arranged on the base 105. A cutting depth limiting rack 6 that is clamped and matched with the elastic hook 503 is fixedly connected to the rotating saw body assembly. A cutting depth limiting contact rod 103 that can be adjusted and matches the cutting depth limiting switch 104 is arranged on the rotating saw body assembly. As Figure 9As shown in the figure, an arc-shaped guide post 109 and a cutting depth ruler 110 are fixed on the base 105. The cutting depth ruler 110 is also an arc-shaped structure, and the upper end of the cutting depth ruler 110 is fixedly connected to the arc-shaped guide post 109. A guide seat 108 is fixed on the rotating saw body assembly. Both the cutting depth ruler 110 and the arc-shaped guide post 109 pass through the guide seat 108 and are slidably matched 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 limit and external force, so that the saw blade does not contact the plate, forming Figure 8 the structure shown in the figure.

[0037] A cutting depth limit block 8 is slidably connected to the cutting depth ruler 110. The cutting depth limit block 8 is used to preset the cutting depth. An adjusting bolt 801 that cooperates with the cutting depth ruler 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 the cutting depth limit block 8 can be positioned by tightening the adjusting bolt 801, completing 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 limit contact rod 103 is used in cooperation with the cutting depth adjusting rod 1081. After determining the actual cutting depth, the length of the cutting depth limit contact rod 103 is synchronously adjusted so that when the cutting depth adjusting rod 1081 abuts against the cutting depth limit block 8, the cutting depth limit contact rod 103 can also contact the cutting depth limit switch 104. During operation, the operator adjusts the heights of the cutting depth limit block 8, the cutting depth adjusting rod 1081, and the cutting depth limit contact rod 103 according to the thickness of the plate. When the rotating saw body assembly presses down to a suitable position, the cutting depth limit contact rod 103 contacts the cutting depth limit 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 limit rack 6, completing the positioning of the rotating saw body assembly.

[0039] As Figures 9 to 14 shown, the automatic feeding method uses the above-mentioned automatic feeding track saw, including the following steps: S1. Preparation work. Place the plate to be cut at the bottom of the guide rail 2 to ensure the accurate position of the plate and avoid movement during the sawing process. The operator adjusts the cutting depth of the rotating saw body assembly according to the thickness of the plate to ensure that the sawing depth meets the requirements.

[0040] The cutting depth adjustment method is as follows: 1.1. Loosen the adjusting bolt 801, and slide the cutting depth limit block 8 along the cutting depth ruler 110 to the corresponding position according to the cutting depth requirement, so that the upper end of the cutting depth limit block 8 is aligned with the corresponding cutting depth scale line, and tighten the adjusting bolt 801 to fix the cutting depth limit block 8 at this position to achieve the preset cutting depth; 1.2. The cutting depth adjustment rod 1081 can be rotated to fine-tune the preset cutting depth to ensure its accuracy. When the saw body assembly is pressed down and rotated, the cutting depth adjustment rod 1081 abuts against the upper end of the cutting depth limit block 8; 1.3 Rotate the cutting depth limit touch rod 103, and synchronously adjust the height of the cutting depth limit touch rod 103, 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 touch rod 103 can contact the cutting depth limit switch 104; the cutting depth limit touch rod 103 is used to trigger the cutting depth limit switch 104 on the one hand, and on the other hand, it plays the role of shock absorbing and limiting, so as to avoid vibration or shaking of the rotating saw body assembly during the sawing process, which affects the cutting quality.

[0041] 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 drops accordingly. When the rotating saw body assembly is pressed down to the right position, the cutting depth limit contact rod 103 contacts the cutting depth limit switch 104, and the cutting depth limit switch 104 immediately starts the steering gear 504, which drives the elastic hook 503 to rotate. Since the elastic hook 503 has a certain elasticity and flexibility, the hook 5033 on the elastic hook 503 can be smoothly stuck in 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 sawing depth are ensured, and the sawing quality is improved.

[0042] 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 starts the feed switch 102, and the feed switch 102 controls the automatic feed mechanism 4 to start. At the same time, the operator starts the sawing power mechanism 106 through the sawing switch, and the feed power mechanism 402 in the automatic feed mechanism 4 drives the feed gear 405 to rotate, and the feed gear 405 is engaged with the feed rack 3, driving the track saw body 1 to automatically move forward along the guide rail 2. At the same time, the sawing power mechanism 106 drives the saw blade 901 to rotate at a high speed to automatically cut the plate. During the cutting process, the operator can adjust the feed speed of the track saw body 1 according to the actual situation through the feed speed control button 101 to ensure the cutting effect.

[0043] S4. Manual cutting. When encountering some special situations, such as fine-tuning the cutting accuracy or manual cutting is required when the automatic feeding of the equipment fails, the operator can turn off the automatic feeding mechanism 4 and cut by manually pushing the rail saw body 1 forward. Manual cutting can rely on the operator's operation experience and skills to better meet some complex cutting requirements.

[0044] 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 II 410 or the obstacle is detected by the proximity switch, the sawing power mechanism 106 and the automatic feeding mechanism 4 will be quickly controlled to stop, avoiding the equipment from colliding with the obstacle and being damaged. At the same time, the servo motor 504 starts, driving the elastic hook 503 to rotate, so that it disengages from the cutting depth limit rack 6, and the saw body assembly rotates in reverse to reset, 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.

[0045] Finally, although this specification is described according to the embodiments, not each embodiment only contains 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.
