Description
TECHNICAL FIELD
[0001] The utility model relates to a dismounting structure field, especially a dismounting structure and circular saw blade thereof. BACKGROUND
[0002] In the existing design of circular saw blade, the installation and dismounting of the circular saw blade usually rely on the tightening of the nut to realize the compression and fixation of the circular saw blade. Although this traditional fixation method is simple in structure, it has some significant defects in actual use.
[0003] During the cutting process, the contact between the circular saw blade and the work material will generate uneven cutting force, especially when cutting hard materials or encountering knots and inclusions, the cutting force will suddenly increase, causing instantaneous vibration of the circular saw blade. The repeated movement caused by the vibration will cause the surface of the thread to wear, which will further affect the fastening effect of the nut, resulting in unstable connection. The worn thread not only weakens the fixation force, but also can cause further loosening of the nut during use. When the nut is loose, the circular saw blade may deviate, resulting in a decrease in cutting accuracy, and even falling off. The falling-off circular saw blade under high-speed rotation will cause serious safety hazards to the operator and the surrounding environment, which may cause equipment damage, personal injury or workplace accidents.

DETAILED DESCRIPTION
[0037] The technical scheme in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings of the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0038] The utility model provides a kind of Figures 1-4The detachable structure and the circular saw blade thereof shown, comprising: a rack 1, which is a hollow shell structure; a motor 2, which is installed inside the rack 1; an assembling device 3, which is connected to one end of the motor 2, and the motor 2 drives the rotation of the assembling device 3, facilitating the assembly of the circular saw blade through the assembling device 3.
[0039] The assembling device 3 comprises: a connecting mechanism 31 connected with the output end of the motor 2; a pressing plate 32 connected with the connecting mechanism 31; a threaded pressing mechanism 33 threadedly connected to one end of the connecting mechanism 31, used for pressing the pressing plate 32; and a locking positioning mechanism 34 slidingly arranged outside the threaded pressing mechanism 33 and used for positioning the pressing plate 32. When the circular saw blade is assembled, the circular saw blade is first inserted outside the connecting mechanism 31, and then the pressing plate 32 is pressed on the circular saw blade. At this time, the first positioning column 314 simultaneously positions the circular saw blade and the pressing plate 32, so as to realize synchronous fixation. Then, when the locking positioning mechanism 34 is tightened outside the connecting mechanism 31, the locking positioning mechanism 34 is inserted through the threaded pressing mechanism 33 and the pressing plate 32, so as to be clamped between the pressing plate 32 and the threaded pressing mechanism 33 through the locking positioning mechanism 34, realizing the position limiting of the threaded pressing mechanism 33, preventing the loosening of the threaded pressing mechanism 33, making the pressing of the threaded pressing mechanism 33 more stable, preventing the circular saw blade from falling off, and making the use of the circular saw blade more secure.
[0040] The connecting mechanism 31 comprises: a connecting seat 311 drivingly connected with the output end of the motor 2; a threaded rod 312 fixedly connected with the connecting seat 311; a fixed seat 313 fixedly sleeved outside one end of the threaded rod 312; and a plurality of first positioning columns 314 fixedly installed on the fixed seat 313, and a plurality of first insertion holes matched with the first positioning columns 314 are formed on the pressing plate 32. The threaded rod 312 facilitates the insertion positioning of the circular saw blade and the pressing plate 32, the fixed seat 313 facilitates the limiting and bearing of the relative position between the circular saw blade and the threaded rod 312, preventing the excessive assembly of the circular saw blade relative to the threaded rod 312, the first positioning columns 314 are simultaneously clamped between the circular saw blade and the pressing plate 32, so as to limit the relative position between the circular saw blade and the pressing plate 32, making the pressing plate 32 and the circular saw blade only axially slide relative to the fixed seat 313, but not radially rotate, so as to make the position of the pressing plate 32 and the circular saw blade more stable.
[0041] The threaded pressing mechanism 33 comprises a nut seat 331, the nut seat 331 is externally threaded on the other end of the threaded rod 312; a connecting ring 332, the connecting ring 332 is fixedly connected to one end of the nut seat 331, the connecting ring 332 is used for pressing the pressing plate 32; a connecting disc 333, the connecting disc 333 is fixedly connected to the other end of the nut seat 331, by screwing the nut seat 331, the connecting ring 332 is facilitated to move relative to the pressing plate 32, so that the connecting ring 332 is pressed to the pressing plate 32, so that the circular saw blade can be pressed between the fixing seat 313 and the pressing plate 32, so as to realize the assembly of the circular saw blade, and the connecting disc 333 is used for limiting the end of the spring 343.
[0042] Specifically, the anti-loose positioning mechanism 34 comprises a sliding ring 341, the sliding ring 341 is externally sleeved on the nut seat 331; a plurality of second positioning columns 342 are fixedly installed on the sliding ring 341, the second positioning column 342 is slidably connected with the connecting ring 332, and a plurality of second penetrating holes are formed in the pressing plate 32 and matched with the second positioning column 342; a spring 343 is movably sleeved on the outside of the nut seat 331, and the spring 343 is used for elastically supporting the sliding ring 341. The anti-loose positioning mechanism 34 further comprises a rotating support rod 344, rectangular grooves are formed on both sides of the sliding ring 341, one end of the rotating support rod 344 is rotatably connected with the inner cavity of the rectangular groove, and a clamping groove is formed in the connecting ring 332 and matched with the rotating support rod 344, the clamping groove is used for clamping the rotating support rod 344 in the vertical state, and the spring 343 is compressed and deformed, so as to elastically support the sliding ring 341, so that the second positioning column 342 can be penetrated with the connecting ring 332 and the pressing plate 32 at the same time, and the second positioning column 342 is clamped between the connecting ring 332 and the pressing plate 32 at the same time, so as to limit the relative position between the connecting ring 332 and the pressing plate 32. Since the position of the pressing plate 32 is stably positioned by the first positioning column 314, the radial position of the connecting ring 332 is stable at this time, so as to prevent the nut seat 331 from being loosened. When the circular saw blade needs to be disassembled, the rotating support rod 344 is lifted up, so that the sliding ring 341 is extruded and deformed after the spring 343, the rotating support rod 344 is rotated to the vertical state with the sliding ring 341, and then the end of the rotating support rod 344 is clamped in the clamping groove. The spring 343 elastically supports the rotating support rod 344 and the clamping groove, so that the clamping between the rotating support rod 344 and the clamping groove is more stable, and the rotating support rod 344 is supported between the sliding ring 341 and the connecting ring 332. Thus, the sliding ring 341 drives the axial movement of the second positioning column 342 synchronously, so that the second positioning column 342 is separated from the penetration between the second penetrating hole. At this time, the second positioning column 342 no longer limits the relative position between the connecting ring 332 and the pressing plate 32, so that the nut seat 331 can be loosened and disassembled, so as to realize the disassembly of the circular saw blade.
[0043] As Figure 1 The embodiment provides a circular saw blade, which comprises the dismounting structure.
