For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Figure 1 , Figure 2 , Figure 3 and Figure 4 An angle grinder with a follow-up rapid dust removal and cooling device is shown, comprising a bottom operating table 1, on which a plurality of electrically-controlled flip fixed claws 2 are installed, an electrically-controlled adjustment guide rail 3 is installed on the bottom operating table 1 at the periphery of the electrically-controlled flip fixed claws, an arc-shaped electrically-controlled angle grinding head 4 is installed on the electrically-controlled adjustment guide rail 3, and a high-speed water-cooling and dust removal module 5 is installed on the outer side of the arc-shaped electrically-controlled angle grinding head 4.

[0028] In order to facilitate the turning adjustment, a plurality of strip-shaped turning grooves 6 for mounting the electrically controlled turning fixing claws 2 are provided on the upper surface of the bottom operating table 1 .

[0029] In order to adjust the angle and clamp the outside of the workpiece, the electrically controlled flipping and fixing claw 2 includes an arc-shaped clamping arm 21 movably installed inside the strip-shaped flipping groove 6 through a rotating shaft and an embedded flipping support rod 22 for controlling the flipping of the arc-shaped clamping arm 21 .

[0030] The embedded flip support rod 22 controls the arc-shaped clamping arm 21 to perform flipping adjustment by telescoping.

[0031] In order to cooperate with horizontal adjustment, the electrically controlled adjustment guide rail 3 includes an annular embedded guide rail 31 fixedly installed on the bottom operating table 1, an internal adjustment ring 32 movably installed inside the annular embedded guide rail 31, a transverse guide rail 33 fixedly installed on the upper surface of the internal adjustment ring 32, and a side-mounted adjustment gear 34 meshing with the outer tooth surface of the internal adjustment ring 32.

[0032] The side-mounted adjustment gear 34 controls the adjustment of the internal adjustment ring 32 inside the annular embedded guide rail 31 by rotation, and the arc guide rail 33 is composed of a transverse guide rail fixed on the upper surface of the internal adjustment ring 32, a transverse screw rod movably installed inside the transverse guide rail, and an internal thread translation block threadedly mounted on the transverse screw rod.

[0033] In order to facilitate adjustment, the arc-shaped electric-controlled angle grinding head 4 includes an arc-shaped guide rail 41 slidably mounted on the horizontal guide rail 33, an arc-shaped adjustment frame 42 slidably mounted inside the arc-shaped guide rail 41, an assembly frame 43 with a movable axis connected to the arc-shaped adjustment frame 42, a grinding head 44 movably mounted inside the assembly frame 43, an electric-controlled worm 45 for controlling the sliding adjustment of the arc-shaped adjustment frame 42, and a lateral support rod 46 for controlling the flipping of the assembly frame 43.

[0034] The arc guide rail 41 is fixed to the upper end of the internal thread translation block.

[0035] The arc-shaped adjustment frame 42 is slidably adjusted along the inner side of the arc-shaped guide rail 41 , and the lateral support rod 46 is telescopically adjusted to adjust the angle of the assembly frame 43 , thereby changing the angle of the grinding head 44 .

[0036] In order to cooperate with heat dissipation and dust removal, the high-speed water-cooling and dust removal module 5 includes a lateral isolation cover 51 fixed on the arc-shaped adjustment frame 42, an arc-shaped air guide cover 52 fixed on the side wall of the lateral isolation cover 51, a lateral functional cover 53 fixed on the outside of the arc-shaped air guide cover 52, a cooling water tank 54 installed on the lateral functional cover 53, a water-cooling module installed on the arc-shaped air guide cover 52, a high-speed fan 55 installed inside the lateral functional cover 53, and a detachable filter 56.

[0037] The lateral isolation covers 51 are arranged on both sides of the assembly frame 43 and the grinding head 44 .

[0038] A loading and unloading port is provided on the outer side of the lateral functional cover 53 to facilitate the loading and unloading of the detachable filter 56. The detachable filter 56 is used to filter the air drawn into the inside of the lateral functional cover 53 to avoid the impurities in the drawn air being introduced into the high-speed fan 55. At the same time, a collecting hopper is provided at the low end of the detachable filter 56 to facilitate the deposition of filtered dust at the bottom and to avoid separation and falling off when the detachable filter 56 is disassembled.

[0039] In order to facilitate assembly and not affect sliding adjustment, the arc-shaped air guide cover 52 and the lateral functional cover 53 are located at the periphery of the arc-shaped guide rail 41 .

[0040] In order to cooperate with water cooling, the water cooling module includes an arc-shaped heat-conducting copper sheet 7 fixed on the inner wall of the arc-shaped air guide cover 52, a serpentine-shaped external heat exchange copper tube 8 fixed on the outside of the arc-shaped heat-conducting copper sheet 7, and a circulating water pump 9 installed inside the cooling water tank 54.

[0041] The circulating water pump 9 is started to introduce the coolant inside the cooling water tank 54 into the external heat exchange copper tube 8. The heat inside the arc-shaped air guide cover 52 is dissipated externally through the external heat exchange copper tube 8 fixedly connected to the arc-shaped heat-conducting copper sheet 7, thereby increasing the heat inside the arc-shaped air guide cover 52, thereby blowing the cooled air toward the grinding head 44 again, thereby quickly reducing the temperature.

[0042] In order to improve the installation firmness, a mounting slot is opened on the lateral extrusion surface of the arc-shaped clamp arm 21, a rubber anti-skid pad 23 is inserted into the mounting slot, and a pressure sensor module 10 is fixed on the inner wall of the mounting slot on the connection surface of the rubber anti-skid pad 23.

[0043] The arc-shaped clamp arm 21 is pressed against the surface of the workpiece through the rubber anti-skid pad 23, and then the pressing force is monitored by the pressure sensor module 10 to determine the installation firmness and stability.

[0044] In order to change the angle of the arc-shaped adjustment frame 42 , an arc-shaped worm wheel 11 meshing with the electric-controlled worm 45 is provided on the arc-shaped connection surface of the arc-shaped adjustment frame 42 .

[0045] The electric-controlled worm 45 is rotated to drive the meshing arc worm wheel 11 to slide and adjust, thereby changing the angle of the arc adjustment frame 42 , so that the assembly frame 43 thereon and the grinding head 44 located inside the assembly frame 43 can be adjusted in height along the arc guide rail 41 .

[0046] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
