Description

Technical Field

[0001] The invention relates to the field of sawtooth welding, and in particular to a saw blade sawtooth welding device. Background Art

[0002] Saw blade is a general term for thin circular cutting tools used to cut solid materials. The saw blade is provided with evenly distributed teeth, which can be used to cut objects. A welding device is required when installing the saw teeth.

[0003] In the process of using the saw blade serration welding device, the existing saw blade serration welding device often has two disadvantages when in use. First, the existing saw blade serration welding device often adopts the method of welding from both sides when in use. However, due to the different thicknesses of the saw blades, the saw blade cannot be adjusted to be fixed in the center when fixing the saw blade, so that one side will contact the saw teeth first during welding, resulting in unstable welding. Second, the existing saw blade serration welding device often generates a lot of dust during welding when in use, causing harm to the human body. Summary of the Invention

A pair of matching clamps 23 that can clamp the saw blade 27 for concentric rotation are provided between the first limiting plate 20 and the second limiting plate 24, wherein one of the limiting plates is provided with a first servo or stepper motor that drives the clamp to rotate, and the other clamp is rotatably mounted on the other limiting plate; preferably, the first servo or stepper motor is mounted on the first limiting plate 20, and a pair of clamps are provided with a rotating shaft and a supporting sleeve 21 connected to the corresponding limiting plate, and a pressure bearing coaxial with the rotating shaft is provided between the corresponding clamp and the matching supporting sleeve; the rotating shaft of the clamp that matches the first servo or stepper motor passes through the corresponding supporting sleeve and is connected to the shaft of the first servo or stepper motor. The specific structure of the rotating shaft on a pair of clamps may be inconsistent, such as Figure 2-3 The rotating shafts of the pair of clamping plates employ different structures depending on the connection requirements. Between the pair of clamping plates 23, a guide shaft is located on each clamping plate, concentric with the rotating shaft and locating the axial hole of the saw blade 27. The combined length of the guide shafts on both clamping plates is less than the thickness of the saw blade. Guide heads are provided at the ends of the guide shafts. The two clamping plates can be circular.

[0025] The lower sides of the first limit plate 20 and the second limit plate 24 are both threadedly connected to the threaded rod 13, and the left and right ends of the threaded rod 13 are rotatably connected to the support column 6 through bearings 14. Evenly distributed positioning guide shafts 5 are provided on the left and right sides of the upper portion of the threaded rod 13. The positioning guide shafts 5 respectively pass through the first limit plate 20 and the second limit plate 24, and the ends of the positioning guide shafts 5 away from each other are fixedly connected to the support column 6. The positioning guide shafts 5 can limit the limit plates so that the first limit plate 20 and the second limit plate 24 can move on the threaded rod 13. The left periphery of the threaded rod 13 is fixedly connected to the first bevel gear 7, and the bottom of the first bevel gear 7 is meshed with the second bevel gear 8. The second bevel gear 8 is fixedly connected to the top of the motor 9, and the second bevel gear can be driven by the motor 9. The gear 8 rotates, thereby driving the first bevel gear 7 to rotate. Since the first bevel gear 7 is fixed to the threaded rod 13, the threaded rod 13 can rotate. A box 10 is provided in the middle of the bottom end of the device body 1. The left side wall of the box 10 is fixedly connected to evenly distributed fans 11. The fans 11 are all arranged on the left side of the filter 12. A dust collection bin 4 is arranged on the right side of the filter 12. A dust suction pipe 15 is provided on the right side of the top of the box 10. The end of the dust suction pipe 15 away from the box 10 passes through the fixed block 16 and is fixedly connected to the dust hood 17. By starting the fan 11, a negative pressure can be formed inside the box 10, so that when in use, the dust generated during welding can be concentrated through the dust suction pipe 15 and the dust hood 17. A welding mechanism 18 is provided on the rear side of the middle of the top of the workbench 25. The welding mechanism 18 can adopt the existing welding manipulator structure, and can include a welding manipulator and a mechanism that cooperates with the saw blade to perform sawtooth feeding and positioning. The saw blade 27 clamped by a pair of clamps can be driven by a first servo or stepper motor to rotate tooth by tooth according to a set rotation angle, and cooperate with the welding mechanism to weld the saw teeth.

[0026] A protective door 2 is slidably connected to the middle of the upper front end of the device body 1 through a slide 3. The protective door 2 is transparent, so that the working status inside the device body can be observed through the transparent protective door. Welding heads 22 are provided on both the left and right sides of the middle front end of the welding mechanism 18. The motor 9 is provided on the left side of the device body 1. The front end of the dust collection bin 4 passes through the box body 10 and the front of the device body 1 in sequence. The inhaled dust will fall into the dust collection bin 4 under the obstruction of the filter 12 and the action of gravity, making it convenient for people to use. The workbench 25 is provided in the middle of the device body 1. The filter 12 is fixedly connected to the left side of the middle inside the box body 10. The top of the fixed block 16 is fixedly connected to the right side of the middle bottom end of the workbench 25.

[0027] Working principle: When in use, it is best to center the first limit plate 20 and the second limit plate 24 through debugging, and symmetrically set them at the corresponding positions of the threaded rod 13, so that they can quickly and accurately cooperate with the welding mechanism 18. First, when in use, the motor 9 can drive the second bevel gear 8 to rotate, thereby driving the first bevel gear 7 to rotate. Since the first bevel gear 7 is fixed to the threaded rod 13, the threaded rod 13 can be rotated. The left and right sides of the threaded rod 13 have different thread rotation directions. The first limit plate 20 and the second limit plate 24 are respectively provided on the left and right sides of the threaded rod 13. The limit plate can be limited by the positioning guide shaft 5, so that the first limit plate 20 and the second limit plate 24 can move smoothly on the threaded rod 13. Since the first limit plate 20 and the second limit plate 24 are symmetrically distributed on the threaded rod 13, when the limit plate is moved by rotating the threaded rod 13 When the saw blade is clamped and fixed, the moving speed of the limit plate is consistent with the forward distance, so that the saw blade can be fixed in the center when it is clamped and fixed, thereby avoiding the situation that one side contacts the saw teeth first during welding, resulting in unstable welding, which is beneficial to production and processing. A box body 10 is provided inside the device body 1, and a fan 11 is provided inside the box body 10. By starting the fan 11, a negative pressure can be formed inside the box body 10, so that the dust generated during welding can be concentrated through the dust suction pipe 15 and the dust suction hood 17 when in use. The inhaled dust will fall into the dust collecting bin 4 under the obstruction of the filter screen 12 and the action of gravity, making it convenient for people to use.
