Description

Technical Field

[0001] This invention relates to the field of saw blade grinding technology, and more particularly to saw blade clip changer clamps. Background Technology

[0002] With the rapid development of the semiconductor industry, saw blades are widely used in cutting and machining industrial applications, facilitating material preparation and product processing. However, after a period of use, saw blades are prone to deformation, burrs, regional breakage, and tooth wear, resulting in a sharp reduction in lifespan and increased production costs. Continuing to use defective saw blades can also lead to a decrease in product qualification rates, affecting subsequent processing and production.

[0003] In related technologies, the cutting performance of saw blades is basically restored by re-sharpening the saw teeth, meeting the requirements for continued use and thus extending the service life of the saw blades. Other related technologies involve cutting new cutting bits onto the original saw teeth of the saw blade to restore its cutting function. However, cutting cutting bits onto the saw blade requires the use of corresponding clamps to fix the saw blade. Because saw blades come in various sizes, existing clamps cannot accommodate saw blades of multiple sizes. Furthermore, because the wear and deformation caused by each type of saw blade are inconsistent, after the saw blade is fixed in the clamp, it may wobble left or right or arch forward or backward, and the saw blade may not be level, causing it to shake. After cutting cutting bits onto the saw blade, the cutting bits cut from different saw teeth on the same saw blade are inconsistent, resulting in unstable performance of the repaired saw blade and failing to meet the requirements for continued use.

[0004] There is still a lack of better technical solutions to the problems of poor universality of clamps for clamping saw blades of different sizes, saw blade wobbling, and inconsistent cutting bits in related technologies. Summary of the Invention

[0005] In view of this, it is necessary to provide a saw blade clipping fixture to at least solve the problems in the related art of saw blade clamps having poor universality for saw blades of different sizes, saw blade wobbling, and inconsistent cutting clips.

[0006] This invention provides a saw blade insert changer, including a tilting assembly, a swaying assembly, a saw blade locking assembly, a clamping assembly, and a pull saw blade assembly. The tilting assembly is mounted on a machine base, the swaying assembly is mounted on the tilting assembly, and the saw blade locking assembly is mounted on and connected to the swaying assembly. The clamping assembly and the pull saw blade assembly are located on the side of the saw blade locking assembly opposite to the locking assembly. The clamping assembly is positioned directly opposite the locking assembly, and the pull saw blade assembly is located beside the saw blade locking assembly. The saw blade locking assembly is used to adjust the position of the locking device so that the saw teeth of the saw blade locked by the locking device are placed in a preset cutting area, and to enable the saw blade assembly to hook the corresponding saw teeth and pull the saw blade to rotate a preset angle. The swaying component is used to drive the swaying component, the saw blade locking component and the saw blade to sway left and right, and to drive the saw blade locking component and the saw blade to sway back and forth in conjunction with the swaying component, so as to adjust the locked saw blade to a preset reference horizontal plane. The clamping assembly is used to clamp and fix the saw blade that has been leveled and / or rotated at a preset angle, so that the cutter can smoothly cut the saw teeth.

[0007] In one embodiment, the saw blade locking assembly includes a mounting base plate with a groove. A linear transmission unit is disposed within the groove. The locking device is fixed to a slider of the linear transmission unit and can move along a guide of the linear transmission unit following the slider to adjust the position of the locking device. The end of the mounting base plate opposite to the locking device also includes a support component and a limiting component. The support assembly includes a top support unit and a support head. The support head is fixed on the output shaft of the top support unit, and the top support unit is fixed on the mounting base plate. The top support unit drives the support head to move vertically to support the saw blade locked by the locking device. The limiting component includes a telescopic limiting post movably mounted on the mounting base plate. After the saw blade assembly hooks the saw teeth of the cutter and drives the saw blade to rotate at a preset angle, the telescopic limiting post is driven to extend to limit and fix the rotation of the saw blade.

[0008] In one embodiment, the linear drive unit includes a ball screw.

[0009] In one embodiment, the sway assembly includes a base plate, a T-shaped hinge seat, a sway plate, and a rotary adjuster. The base plate is fixed to the machine base. A T-shaped hinge seat is provided on each side of the base plate along its length. The T-shaped hinge seat is embedded in a groove at a corresponding position on the sway plate and is movably connected to the sway plate via a hinge shaft. Two rotary adjusters are provided on one side of the base plate along its width and spaced apart. The rotary adjusters are in movable contact with the wedge bottom surface of the sway plate. Twisting one of the two rotary adjusters causes the corresponding rotary adjuster to touch the corresponding wedge bottom surface, and causes the sway plate to drive the sway assembly, the saw blade locking assembly, and the saw blade to sway left and right around the hinge shaft.

[0010] In one embodiment, the rotary adjuster includes a rotary nut and a top cap. One axial end of the rotary nut has a convex surface, and one axial end of the top cap has a wedge-shaped surface adapted to the convex surface. The rotary nut is installed in a first mounting hole formed in the base plate and extending horizontally, and the top cap is installed in a second mounting hole formed in the base plate and extending vertically, with the wedge-shaped surface in movable contact with the convex surface. When the rotary nut is turned, it moves along the first mounting hole. The convex surface rotates and pushes the wedge-shaped surface, causing the top cap to move vertically along the second mounting hole, so that the top cap touches the bottom surface of the corresponding wedge and causes the deflector plate to deflect.

[0011] In one embodiment, the rocker assembly includes a rocker shaft connector, a rocker connecting rod, a rocker top unit, a limiter, and adjustable buoyancy buffers. The rocker shaft connector is fixed to the middle of the rocker plate and pivotally connected to the rocker connecting rod. The rocker connecting rod is fixed to the mounting base plate. The rocker top unit is fixed to the side of the base plate away from the rotary tuner, and the rocker top unit also penetrates the rocker plate and movably abuts against the mounting base plate. The limiter is fixed to the side of the rocker plate near the rotary tuner and movably engages or disengages from a limiting groove at the bottom of the mounting base plate. Two adjustable buoyancy buffers are provided on the top of the side of the rocker plate near the rotary tuner, and the two adjustable buoyancy buffers are positioned on both sides of the width direction of the rocker plate. The tilting unit is used to tilt the mounting base plate, causing the tilting connecting rod to pivot relative to the tilting shaft connecting seat, so that the mounting base plate tilts back and forth. The limiter is used to limit the forward and backward tilting of the mounting base plate; The adjustable floating buffer is used to support the mounting base plate which is swaying back and forth, and provides elasticity to float and adjust the swaying amplitude of the mounting base plate.

[0012] In one embodiment, the tilting unit includes a drive cylinder, the piston shaft of which is connected to a top that tilts the mounting base plate; and / or, The adjustable buoyancy buffer includes an adjusting nut, a push block, and a buoyancy spring. One axial end of the adjusting nut has a wedge surface, and one axial end of the push block has a tongue surface adapted to the wedge surface. The adjusting nut is installed in a third mounting hole formed in the sway plate and extending horizontally, and the push block is installed in a fourth mounting hole formed in the sway plate and extending vertically, with the tongue surface in movable contact with the wedge surface. When the adjusting nut is turned, it moves along the third mounting hole, and the wedge surface rotates and pushes the tongue surface, causing the push block to move vertically along the fourth mounting hole to adjust the compression amplitude of the buoyancy spring.

[0013] In one embodiment, the clamping assembly includes a mounting base fixed to the mounting base on the side opposite to the locking device. The mounting base has at least one T-shaped support. The T-shaped support is movably connected to a crank connecting rod via a rotating shaft. The end of the crank connecting rod away from the T-shaped support is movably connected to a pressure rod via a connecting shaft. The pressure rod is also drivenly connected to a lifting unit mounted on the mounting base. A chuck is fixed to the end of the pressure rod away from the lifting unit. The lifting unit drives the pressure rod to rotate around the rotating shaft as a fulcrum, thereby causing the pressure head to clamp the corresponding saw blade.

[0014] In one embodiment, the saw blade assembly includes a material pulling drive unit fixedly disposed on the side of the mounting base plate. The telescopic shaft of the material pulling drive unit has a groove, and a puller head connected to the telescopic shaft via a central shaft is disposed within the groove. A damper is also disposed within the groove, with one end fixedly connected to the telescopic shaft and the other end movably contacting the puller head. The puller head can rotate about the central axis to retract into the groove or pop out from the groove; The damper is compressed when the auger is pushed back into the groove by the saw blade, so as to provide a spring force to eject the auger from the groove when the auger is not blocked by the saw blade. After the puller head pops out of the groove and hooks the corresponding saw tooth, the material pulling drive unit drives the telescopic shaft to drive the puller head to pull the saw blade to rotate a preset angle, and drives the telescopic shaft to drive the puller head retracted into the groove to the position where it hooks the corresponding saw tooth.

[0015] In one embodiment, the drawing material drive unit includes one of the following: a drive cylinder, a linear motor, and / or, the damper includes a compression spring.

[0016] Compared with the prior art, the saw blade clip changing fixture provided in this application adopts a configuration of a swaying assembly, a tilting assembly, a saw blade locking assembly, a clamping assembly, and a pull saw blade assembly. The swaying assembly is mounted on a machine base, the tilting assembly is mounted on the swaying assembly, the saw blade locking assembly is mounted on the tilting assembly, and the tilting assembly is connected to the saw blade locking assembly. The clamping assembly and the pull saw blade assembly are located on the side of the saw blade locking assembly away from the locking device. The clamping assembly is positioned directly opposite the locking device, and the pull saw blade assembly is located beside the saw blade locking assembly. The position of the locking device is adjusted by the saw blade locking assembly so that the saw teeth of the saw blade locked by the locking device are placed in a preset cutting area. The saw blade assembly is designed to hook onto the corresponding saw teeth and pull the saw blade to rotate a preset angle. The swaying assembly drives the tilting assembly, the saw blade locking assembly, and the saw blade to sway left and right. The tilting assembly, in turn, drives the saw blade locking assembly and the saw blade to tilt back and forth, adjusting the locked saw blade to a preset horizontal plane. The clamping assembly clamps and fixes the leveled and / or rotated saw blade at a preset angle, ensuring the cutter smoothly cuts the saw teeth. This solves the problems of poor adaptability of saw blade clamps to different sizes, saw blade wobbling, and inconsistent cutting patterns in related technologies. It achieves the beneficial effects of adapting to saw blade grinding of different sizes, stable and horizontal saw blade clamping without wobbling, and high consistency in the cutting patterns.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Please see Figures 1 to 10 This application provides a saw blade insert changer, including a sway assembly 100, a tilting assembly 200, a saw blade locking assembly 300, a clamping assembly 400, and a saw blade assembly 500. The sway assembly 100 is mounted on a machine base 600, the tilting assembly 200 is mounted on the sway assembly 100, and the saw blade locking assembly 300 is mounted on and connected to the tilting assembly 200. The clamping assembly 400 and the saw blade assembly 500 are located on the side of the saw blade locking assembly 300 away from the locking device 31. The clamping assembly 400 is positioned directly opposite the locking device 31, and the saw blade assembly 500 is located beside the saw blade locking assembly 300. The saw blade locking assembly 300 is used to adjust the position of the locking device 31 so that the saw teeth 003 of the saw blade 001 locked by the locking device 31 are placed in a preset cutting area, and to enable the saw blade assembly 500 to hook the corresponding saw teeth 003 and pull the saw blade to rotate a preset angle.

[0023] In this embodiment, the position of the locking device 31 is adjusted according to the diameter of the saw blade 001 to be re-sharpened (see reference). Figure 3 and Figure 4As shown in the figure, that is, adjusting the center position of the saw blade 001, after the saw blade 001 is locked and fixed by the locking device 31, the saw teeth 003 of the saw blade 001 are placed directly below the corresponding tool (not shown in the figure). When the saw blade 001 is pulled to rotate, each rotation will place the next saw blade 003 directly below the corresponding tool. At the same time, the saw blade assembly 500 can hook the corresponding saw teeth 003, that is, the saw teeth 003 are in contact with the head 54 of the saw blade assembly 500. The saw blade assembly 500 drives the head 54 to move along a certain external tangent of the saw blade 003, thereby driving the saw blade 001 to rotate, so that the tool cuts the cutting bits 002 on the saw teeth 003 in sequence. By forming new cutting bits 002, the saw blade 001 restores its cutting performance.

[0024] The sway component 100 is used to drive the sway component 200, the saw blade locking component 300 and the saw blade to sway left and right. In conjunction with the sway component 200, the saw blade locking component 300 and the saw blade to sway back and forth, so as to adjust the locked saw blade to a preset reference horizontal plane.

[0025] In this embodiment, after the locking device 31 locks and fixes the saw blade 001, the swaying component 100 adjusts the swaying component 200 left and right to make the locked saw blade 001 horizontal in the left and right direction; then, the swaying component 200 adjusts the saw blade locking component 300 horizontally in the front and back direction to make the locked saw blade 001 also adjust to a preset horizontal state in the front and back direction, so that the saw blade 001 will not shake during the cutting process of the saw blade 001 cutting the cutting particles 002, and the cutting particles 002 are highly consistent.

[0026] The clamping assembly 400 is used to clamp and fix the saw blade 001 that is leveled and / or rotated at a preset angle, so that the cutter can smoothly cut the saw teeth 003.

[0027] In this embodiment, the saw blade 001 is leveled to a horizontal state or rotated by the saw blade assembly 500 at a certain angle, for example, rotating at least two saw teeth (see reference). Figures 1 to 2 After that, the clamping assembly 400 is activated, and by driving its pressure rod 46, it drives the chuck 48 to press and fix it on the top surface of the saw blade 001, thereby fixing the saw blade 001 in the vertical direction, so that the cutter can smoothly cut the saw teeth 003 of the saw blade 001.

[0028] In this embodiment, after completing one cutting bit, the pull head 54 of the saw blade assembly 500 hooks the corresponding saw tooth 003 (located at the front end of the cutting area in the circumferential direction). By moving the pull head 54 along the corresponding tangential direction, the saw blade 001 is rotated, and the saw tooth 003 that has completed the cutting bit is rotated to the next position, and the saw tooth 003 of the next cutting bit to be replaced is rotated into the cutting area.

[0029] In the aforementioned saw blade insert changer fixture, the position of the locking device 31 is adjusted by the saw blade locking assembly 300 so that the saw teeth 001 of the saw blade 001 locked by the locking device 31 are placed in a preset cutting area, and the saw blade assembly 500 can hook the corresponding saw teeth 003 and pull the saw blade 001 to rotate a preset angle. The swaying assembly 100 drives the swaying assembly 200, the saw blade locking assembly 300, and the saw blade 001 to sway left and right. The swaying assembly 200, in conjunction with the saw blade locking assembly 300, drives the saw blade 001 to move forward. The saw blade 001 is adjusted to a preset reference horizontal plane by tilting back and forth. The saw blade 001, which is leveled and / or rotated at a preset angle, is clamped and fixed by the clamping assembly 400, so that the cutter can smoothly cut the saw teeth 003. This solves the problems of poor universality of clamping saw blades for different sizes, saw blade wobbling, and inconsistent cutting of saw blades in related technologies. It achieves the beneficial effects of adapting to the grinding of saw blades of different sizes, clamping saw blades stably and horizontally without wobbling, and producing highly consistent cutting of saw blades.

[0030] For attachment of saw blades of different sizes, please refer to [reference]. Figures 1 to 6 In some embodiments, the saw blade locking assembly 300 further includes a mounting base plate 32. The mounting base plate 32 has a groove 321, within which a linear transmission unit 33 is disposed. The locking device 31 is fixed on the slider 331 of the linear transmission unit 33 and can move along the guide 332 of the linear transmission unit 33 following the slider 331 to adjust the position of the locking device 31. A support assembly 34 and a limiting assembly 35 are also provided at the end of the mounting base plate 32 opposite to the locking device 31. In this embodiment, the linear transmission unit 33 includes, but is not limited to, a ball screw, the ball nut of the ball screw corresponds to the slider 331, and the screw rod of the ball screw corresponds to the guide 332; in this embodiment, by adjusting the position of the ball nut on the screw rod, the position of the locking device 31 is driven, that is, the locking center of the saw blade 001 is adjusted.

[0031] The support assembly 34 includes a top support unit 341 and a support head 342. The support head 342 is fixed on the output shaft of the top support unit 341, and the top support unit 341 is fixed on the mounting base plate 32. The top support unit 341 drives the support head 342 to move vertically to support the saw blade 001 locked by the locking device 31.

[0032] In this embodiment, the top support unit 341 includes, but is not limited to, a drive cylinder. The top support unit 341 drives the support head to support the bottom end face of the saw blade 001, thereby providing support force on the outer edge of the saw blade 001. With the central support of the locking device 31, the saw blade 001 is stably supported. When the cutter cuts the saw teeth 003 (located on the edge of the saw blade 001), the pressure of the cutter on the outer edge of the saw blade 001 is borne by the support component 34, and the saw blade 001 will not shake, ensuring the consistency of the cutting bits.

[0033] The limiting component 35 includes a telescopic limiting post 351 movably mounted on the mounting base plate 32. After the saw blade assembly 500 hooks the saw teeth 003 of the cut blade and drives the saw blade 001 to rotate at a preset angle, the telescopic limiting post 351 is driven to extend to limit and fix the rotation of the saw blade 001.

[0034] In this embodiment, the saw blade 001 is limited by the limiting component 35 to prevent the saw blade 001 from rotating circumferentially due to the squeezing and pushing of the saw blade 001 during the cutting process of the cutting tool, thereby forming a new cutting tool 002 at the preset position of the saw tooth 003. It can be understood that if the limiting component 35 is not set, when the cutting tool acts on the saw tooth 003, the squeezing and pushing force will cause the saw blade 001 to generate a force that rotates in the circumferential direction, thereby driving the saw blade 001 to rotate a small angle. At this time, the cutting tool 002 cut by the cutting tool will deviate from the original position. Thus, the cutting performance of the refurbished cutting tool 002 does not meet the repair requirements.

[0035] To achieve at least left and right deflection leveling of the sway assembly 200, refer to Figure 1 In some embodiments, the yaw assembly 100 includes a base plate 11, a T-shaped hinge seat 12, a yaw plate 13, and a tuner 14. The base plate 11 is fixed on the machine base 600. A T-shaped hinge seat 12 is provided on both sides of the base plate 11 along its length. The T-shaped hinge seat 12 is embedded in the corresponding slot 131 of the yaw plate 13 and is movably connected to the yaw plate 13 via a hinge shaft 15. Two tuners 14 are installed on one side of the base plate 11 along its width, and are spaced apart. The tuners 14 are in movable contact with the wedge-shaped bottom surface 132 of the yaw plate 13. Twist one of the two rotary knobs 14 so that the corresponding rotary knob 14 touches the bottom surface 132 of the corresponding wedge, and causes the sway plate 13 to drive the sway assembly 200, the saw blade locking assembly 300 and the saw blade to sway left and right around the hinge axis 15.

[0036] In this embodiment, the deflector plate 13 is deflected to the left or right by one of the two rotary knobs 14.

[0037] In this embodiment, the T-shaped hinge seat 12 and the concave connecting seat (not labeled in the drawing) located in the inlay groove 131 are movably connected by the hinge shaft 15. Therefore, when the tuner 14 touches the corresponding wedge bottom surface 132, the deflector plate 13 will deflect left and right with the T-shaped hinge seat 12 as the support axis and the hinge shaft 15 as the fulcrum (deflection direction referenced). Figure 6 (As indicated by arrow A in the image).

[0038] In some embodiments, the rotary tuner 14 includes a rotary nut 141 and a top cap 142. One axial end of the rotary nut 141 has a convex surface 1411, and one axial end of the top cap 142 has a wedge-shaped tongue 1421 adapted to the convex surface 1411. The rotary nut 141 is installed in a first horizontally extending mounting hole 111 formed in the base plate 11, and the top cap 142 is installed in a second vertically extending mounting hole 112 formed in the base plate 11, such that the wedge-shaped tongue 1421 is in movable contact with the convex surface 1411. Tighten the adjusting nut 141 to move along the first mounting hole 111. The inclined convex surface 1411 rotates and pushes the wedge tongue surface 1421 to drive the top cap 142 to move vertically along the second mounting hole 112, so that the top cap 142 touches the corresponding inclined wedge bottom surface 132 and causes the deflector plate 13 to deflect.

[0039] Understandably, when the adjusting nut 141 is turned, it moves inward along the axial direction of the first mounting hole 111. As a result, the inclined convex surface 1411 rotates while moving inward, so that the inclined convex surface 1411 maintains contact with the wedge tongue surface 1421 while also pushing the wedge tongue surface 1421. However, since the top cap 142 is located in the second mounting hole 112, the force of the adjusting nut 141 pushing the top cap 142 to move tilted is decomposed into the thrust of the top cap 142 moving vertically, so that the top cap 142 touches the corresponding inclined wedge bottom surface 132 and causes the deflector plate 13 to deflect.

[0040] In some alternative embodiments, a yaw pin (not labeled) is connected to the yaw plate 13 near the tuner 14 by screws (not labeled in the figure), and a yaw scale line (not labeled in the figure) indicating the yaw angle of the yaw pin is provided on the base plate 11 near the tuner 14.

[0041] To achieve forward and backward tilting of the saw blade locking assembly 300, refer to Figures 1 to 6In some embodiments, the rocker assembly 200 includes a rocker shaft connecting seat 21, a rocker connecting rod 22, a rocker top unit 23, a limiter 24, and adjustable float buffers 25. The rocker shaft connecting seat 21 is fixed to the middle of the rocker plate 13 and pivotally connected to the rocker connecting rod 22. The rocker connecting rod 22 is fixed to the mounting base plate 32. The rocker top unit 23 is fixed to the side of the base plate 11 away from the rotary tuner 14, and the rocker top unit 23 also penetrates the rocker plate 13 and moves to abut against the mounting base plate 32. The limiter 24 is fixed to the side of the rocker plate 13 near the rotary tuner 14 and moves into or out of the limit groove 322 at the bottom of the mounting base plate 32. Two adjustable float buffers 25 are provided on the top of the side of the rocker plate 13 near the rotary tuner 32. The two adjustable float buffers 25 are located on both sides of the width direction of the rocker plate 13. In this embodiment, the rocker link 22 and the rocker shaft connecting seat 21 are movably connected via corresponding rotating shafts (not labeled in the attached drawings). Therefore, when the rocker unit 23 lifts one end (front-to-back direction) of the mounting base plate 32, the mounting base plate 32 will deflect with the rocker link 22 as the support shaft and the rocker shaft connecting seat 21 as the fulcrum (deflection direction referenced). Figure 6 (As shown by arrow B in the diagram), during the deflection process, this rotation axis serves as the center of rotation.

[0042] The tilting unit 23 is used to tilt the mounting base plate 32 and drive the tilting connecting rod 22 to pivot relative to the tilting shaft connecting seat 21, so that the mounting base plate 32 tilts back and forth.

[0043] In this embodiment, the tilting unit 23 includes a drive cylinder 231, and the piston shaft of the drive cylinder 231 is connected to the top head 232 of the tilting mounting base plate 32.

[0044] Limiter 24 is used to limit the front and rear swaying range of the mounting base plate 32.

[0045] An adjustable floating buffer 25 is used to support the mounting base 32 which is tilted back and forth, and provides elasticity to float and adjust the tilting amplitude of the mounting base 32.

[0046] In this embodiment, the adjustable float buffer 25 includes an adjusting nut 251, a push block 252, and a float spring 253. One axial end of the adjusting nut 251 has a wedge surface 254, and one axial end of the push block 252 has a tongue surface 255 adapted to the wedge surface 254. The adjusting nut 251 is installed in a third mounting hole 133 formed in the sway plate 13 and extending horizontally. The push block 252 is installed in a fourth mounting hole 134 formed in the sway plate 13 and extending vertically, with the tongue surface 255 in movable contact with the wedge surface 254. Tighten the adjusting nut 251 to move along the third mounting hole 134, the wedge 254 rotates and pushes the tongue 255 to move the transmission push block 252 vertically along the fourth mounting hole 134 to adjust the compression amplitude of the floating spring 253.

[0047] It is understood that in this embodiment, when the adjusting nut 251 is tightened, the adjusting nut 251 will move inward along the axial direction of the third mounting hole 133. The wedge 254 rotates while moving inward, so that the wedge 254 maintains contact with the push tongue 255 and pushes the push tongue 255. However, since the push block 252 is located in the fourth mounting hole 134, the force of the adjusting nut 251 pushing the push block 252 to move tilted is decomposed into the pushing force of the push block 252 moving vertically, so that the push block 252 lifts the mounting base plate 32 and adjusts the compression amplitude of the floating spring 253.

[0048] To achieve the pressing and securing of saw blade 001, refer to Figures 1 to 4 In some embodiments, the clamping assembly 400 includes a mounting base 41 fixed to the side of the mounting base 32 away from the locking device 31. The mounting base 41 is provided with at least one T-shaped support 42. The T-shaped support 42 is movably connected to a crank connecting rod 44 via a rotating shaft 43. The end of the crank connecting rod 44 away from the T-shaped support 42 is movably connected to a pressure rod 46 via a connecting shaft 45. The pressure rod 46 is also drivenly connected to a lifting unit 47 mounted on the mounting base 41. A clamp 48 is fixed to the end of the pressure rod 46 away from the lifting unit 47. The lifting unit 47 drives the pressure rod 46 to rotate around the rotating shaft 43 as a fulcrum, so as to drive the pressure head 48 to clamp the corresponding saw blade.

[0049] To achieve the rotation of saw blade 001, refer to Figures 1 to 4 as well as Figures 9 to 10 In some embodiments, the saw blade assembly 500 includes a material pulling drive unit 51 fixedly mounted on the side of the mounting base plate 32. The telescopic shaft 52 of the material pulling drive unit 51 has a groove 521. A puller head 54, connected to the telescopic shaft 52 via a central shaft 53, is disposed within the groove 521. A damper is also disposed within the groove 521, with one end fixedly connected to the telescopic shaft 52 and the other end movably contacting the puller head 54. The pull head 54 can rotate about the central axis 53 to retract into the groove 521 or pop out from the groove 521.

[0050] A damper is used to compress the head 54 when it is pushed back into the groove 521 by the saw blade, so as to provide a spring force to eject the head 54 from the groove 521 when the head 54 is not blocked by the saw blade.

[0051] In this embodiment, the damper includes, but is not limited to, a compression spring. After the puller head 54 pops out of the groove 521 and hooks the corresponding saw tooth, the material pulling drive unit 51 drives the telescopic shaft 52 to drive the puller head 54 to pull the saw blade to rotate a preset angle, and the telescopic shaft 52 drives the puller head 54, which retracts into the groove 521, to retract to the position where it hooks the corresponding saw tooth.

[0052] In this embodiment, the drawing material drive unit 51 includes one of the following: a drive cylinder and a linear motor.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
