[0011] Preferably, the method for using the fire extinguisher upper cover deburring device comprises the following steps:

[0012] S1: When grinding the upper cover of the fire extinguisher, the fire extinguisher is placed in the placement slot in the processing table, and the bottom of the fire extinguisher corresponds to the grinding disc in the placement slot. Driven by the screw slide, the carrier moves toward the placement slot. At this time, the clamping device is in a retracted state, and the clamping device penetrates from the top opening of the upper cover of the fire extinguisher to the inner wall of the fire extinguisher. At this time, the driving motor rotates, and the driving motor drives the screw to rotate. The two ends of the moving frame do not contact the carrier plate and the carrier, and then the resistance block moves toward the limit slot in the rotating cylinder under the restriction of the pressure spring. The resistance block and the limit slot on the rotating cylinder are in a card connection. When the screw rotates, the limiting groove on the rotating cylinder is limited by the resistance block, and the rotating cylinder cooperates with the screw to enable the rotating cylinder to move vertically downward. After the rotating cylinder moves vertically downward, the rotating cylinder will drive the outer sleeve to move downward. Due to the magnetic attraction between the bottom of the positioning sleeve and the magnetic attraction block, the positioning sleeve can be limited on the magnetic attraction block. Then, when the outer sleeve moves downward, the connecting frame arranged on the outer sleeve will drive the telescopic rod to expand outward. At this time, the clamping plate on the telescopic rod will contact the inner wall of the upper cover of the fire extinguisher, thereby limiting the fire extinguisher and enabling the polished end surface of the fire extinguisher to be fully polished.

[0013] S2: When the clamping plate expands to the maximum range, the moving frame will contact the surface of the carrying plate, and the moving frame will slide in the limiting frame. When the limiting frame slides, the V-shaped slide groove on the limiting frame will drive the clamping rod on the resistance block to move, thereby separating the resistance block from the limiting groove on the rotating cylinder. When the rotating cylinder is not restricted by the resistance block, the rotation of the screw rod will drive the rotating cylinder to rotate, and the rotation of the rotating cylinder will drive the outer sleeve to rotate. The rotation of the outer sleeve will drive the positioning sleeve to rotate synchronously through the provided clamping frame. At this time, the outer sleeve and the positioning sleeve rotate synchronously, thereby driving the clamped fire extinguisher cover to rotate in the placement groove;

[0014] S3: After the clamping device clamps the inner wall of the upper cover of the fire extinguisher, the outer sleeve rotates to drive the small gear ring set in the clamping position to rotate, and the rotation of the small gear ring drives the large gear ring to rotate slowly, and the large gear ring drives the limiting rod to drive the sliding plate to move through the arc groove. When the sliding plate moves, the hinged frame connected between the sliding plate and the sliding frame will deflect, and the deflection of the hinged frame will drive the rotating rod to rotate, and the rotating rod drives the rotating gear to move the moving tooth plate toward the outer wall of the fire extinguisher. Then, when the clamping device clamps and rotates the upper cover of the fire extinguisher, the grinding block close to the center of the circle of the upper cover of the fire extinguisher can be gradually moved toward the outer edge of the fire extinguisher through the movement of the sliding plate, and the moving tooth plate can be gradually moved downward under the drive of the rotating gear, so that the grinding block on the moving tooth plate moves toward the outer edge of the fire extinguisher and corresponds to the arc-shaped outer wall of the fire extinguisher;

[0015] S4: After the fire extinguisher is polished, the driving motor drives the screw rod to rotate in the opposite direction. When the screw rod rotates in the opposite direction, the movable frame will not continue to squeeze the outer wall of the bearing plate. Driven by the pressure spring, the resistance block and the limit groove on the rotating cylinder will be re-engaged. At this time, the rotation of the screw rod will drive the outer sleeve to move upward, thereby contracting the clamping plate in expansion, so that the upper cover of the fire extinguisher can be taken out of the placement groove. After the upper movable frame contacts the bearing frame, the resistance block and the limit groove on the rotating cylinder will be separated again. At this time, the rotating cylinder drives the outer sleeve to rotate, and the outer sleeve will cause the rotating disk to rotate and reset. Driven by the rotating disk, the polishing part will be reset.

[0016] S5: When the clamping device is unfolded outward, the outer sleeve moves downward, which will drive the clamping frame to move downward, and the bottom of the clamping frame will contact the top of the resistance tube. The resistance tube moves downward under the drive of the clamping frame. When the resistance tube moves downward, the wedge-shaped clamping block arranged on the inner wall of the resistance tube will squeeze the wedge-shaped frame, and the wedge-shaped frame will slide horizontally in the fixed seat. When the wedge-shaped frame slides horizontally, it will drive the wedge-shaped lifting frame to lift upward. The lifting frame moves upward, which drives the pallet to move upward. The four lifting rods arranged on the pallet will drive the grinding disc to move upward.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, when the outer sleeve moves downward, the connecting frame arranged on the outer sleeve will drive the telescopic rod to expand outward. At this time, the clamping plate on the telescopic rod will contact the inner wall of the upper cover of the fire extinguisher, thereby limiting the position of the fire extinguisher and enabling the polished end surface of the fire extinguisher to be fully polished.

[0019] In the present invention, the outer sleeve and the positioning sleeve rotate synchronously, thereby being able to drive the clamped upper cover of the fire extinguisher to rotate in the placement groove. The rotation of the upper cover of the fire extinguisher can cooperate with the subsequent grinding device and the grinding disc lifting device to grind the upper cover and the outer wall of the fire extinguisher, so that the upper cover of the fire extinguisher can grind the outer wall and the bottom at the same time, which improves the working efficiency of the fire extinguisher polishing.

[0020] In the present invention, the grinding block close to the center of the upper cover of the fire extinguisher can be gradually moved toward the outer edge of the fire extinguisher by the movement of the sliding plate, and the movable tooth plate can be gradually moved downward under the drive of the rotating gear, so that the grinding block on the movable tooth plate moves toward the outer edge of the fire extinguisher and corresponds to the arc-shaped outer wall of the fire extinguisher, thereby effectively and comprehensively grinding the outer wall of the upper cover of the fire extinguisher.

[0021] In the present invention, when the wedge-shaped frame slides horizontally, it will drive the wedge-shaped jacking frame to jack up upward, and the upward movement of the jacking frame will drive the tray to move upward, and the four jacking rods set on the tray will drive the grinding disc to move upward, and then when the clamping device drives the fire extinguisher cover to rotate, the grinding disc can effectively contact the bottom of the fire extinguisher cover, so that the bottom of the fire extinguisher cover can be optimally polished.

At this time, the driving motor 21 rotates, and the driving motor 21 drives the screw rod 22 to rotate. The two ends of the moving frame 31 do not contact the carrier disc 24 and the carrier frame 14, and then under the restriction of the pressure spring 35, the resistance block 33 moves toward the limit groove 27 in the rotating cylinder 26, and the resistance block 33 is in a clamping state with the limit groove 27 on the rotating cylinder 26. State, at this time, when the screw rod 22 rotates, since the limiting groove 27 on the rotating cylinder 26 is limited by the abutment block 33, the rotating cylinder 26 and the screw rod 22 are spirally matched to enable the rotating cylinder 26 to move vertically downward.

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown:

[0048] S1: When the upper cover of the fire extinguisher is polished, the fire extinguisher is placed in the placement groove 12 in the processing table 11, and the bottom of the fire extinguisher corresponds to the polishing disc 15 in the placement groove 12. Driven by the screw slide 13, the carrier frame 14 moves toward the placement groove 12. At this time, the clamping device 4 is in a retracted state, and the clamping device 4 penetrates from the top opening of the upper cover of the fire extinguisher to the inner wall of the fire extinguisher. At this time, the driving motor 21 rotates, and the driving motor 21 drives the screw 22 to rotate. The two ends of the moving frame 31 do not contact the carrier plate 24 and the carrier frame 14, and then under the restriction of the pressure spring 35, the resistance block 33 moves toward the limit groove 27 in the rotating cylinder 26, and the resistance block 33 and the limit groove 27 on the rotating cylinder 26 are in a stuck state. When the screw rod 22 rotates, the limiting groove 27 on the rotating cylinder 26 is limited by the abutment block 33, and the rotating cylinder 26 and the screw rod 22 are spirally matched to enable the rotating cylinder 26 to move vertically downward. After the rotating cylinder 26 moves vertically downward, the rotating cylinder 26 will drive the outer sleeve 42 to move downward. Due to the magnetic attraction between the bottom of the positioning sleeve 41 and the magnetic block 47, the positioning sleeve 41 can be limited on the magnetic block 47. Then, when the outer sleeve 42 moves downward, the connecting frame 44 arranged on the outer sleeve 42 will drive the telescopic rod 45 to expand outward. At this time, the clamping plate 46 on the telescopic rod 45 will contact the inner wall of the upper cover of the fire extinguisher, thereby limiting the fire extinguisher and enabling the polished end surface of the fire extinguisher to be fully polished.

[0049] S2: After the clamping plate 46 expands to the maximum range, the movable frame 31 will contact the surface of the carrier plate 24, and the movable frame 31 will slide in the limiting frame 25. When the limiting frame 25 slides, the V-shaped slide groove 32 on the limiting frame 25 will drive the clamping rod 36 on the abutment block 33 to move, thereby separating the abutment block 33 from the limiting groove 27 on the rotating cylinder 26. When the rotating cylinder 26 is not restricted by the abutment block 33, the rotation of the screw rod 22 will drive the rotating cylinder 26 to rotate, and the rotation of the rotating cylinder 26 will drive the outer sleeve 42 to rotate. The rotation of the outer sleeve 42 will drive the positioning sleeve 41 to rotate synchronously through the provided clamping frame 48. At this time, the outer sleeve 42 and the positioning sleeve 41 rotate synchronously, thereby being able to drive the clamped fire extinguisher cover to rotate in the placement groove 12;

[0050] S3: After the clamping device 4 clamps the inner wall of the upper cover of the fire extinguisher, the outer sleeve 42 rotates to drive the small gear ring 53 that is connected to the clamp to rotate, and the rotation of the small gear ring 53 drives the large gear ring 52 to rotate slowly, and the large gear ring 52 drives the sliding plate 61 to move through the arc groove 54. When the sliding plate 61 moves, the hinged frame 68 connected between the sliding plate 61 and the sliding frame 67 will deflect, and the deflection of the hinged frame 68 will drive the rotating rod 63 to rotate, and the rotating rod 63 drives The rotating gear 64 will move the movable tooth plate 65 toward the outer wall of the fire extinguisher, and then when the clamping device 4 clamps and rotates the upper cover of the fire extinguisher, the grinding block 66 close to the center of the upper cover of the fire extinguisher can be gradually moved toward the outer edge of the fire extinguisher through the movement of the sliding plate 61, and the movable tooth plate 65 can be gradually moved downward under the drive of the rotating gear 64, so that the grinding block 66 on the movable tooth plate 65 moves toward the outer edge of the fire extinguisher and corresponds to the arc-shaped outer wall of the fire extinguisher;

[0051] S4: After the fire extinguisher is polished, the driving motor 21 drives the screw rod 22 to rotate in the opposite direction. When the screw rod 22 rotates in the opposite direction, the movable frame 31 will not continue to squeeze the outer wall of the carrier plate 24. Driven by the pressure spring 35, the abutment block 33 and the limiting groove 27 on the rotating cylinder 26 will be re-engaged. At this time, the rotation of the screw rod 22 will drive the outer sleeve 42 to move upward, thereby contracting the clamping plate 46 in the expansion state, so that the upper cover of the fire extinguisher can be taken out of the placement groove 12. After the upper movable frame 31 contacts the carrier frame 14, the abutment block 33 will be separated from the limiting groove 27 on the rotating cylinder 26 again. At this time, the rotating cylinder 26 drives the outer sleeve 42 to rotate, and the outer sleeve 42 will cause the rotating disk 51 to rotate and reset. Driven by the rotating disk 51, the polishing member 6 will be driven to reset.

[0052] S5: When the clamping device 4 is unfolded outward, the outer sleeve 42 moves downward, which will drive the clamping frame 48 to move downward, and the bottom of the clamping frame 48 will contact the top of the contact cylinder 72. The contact cylinder 72 moves downward under the drive of the clamping frame 48. When the contact cylinder 72 moves downward, the wedge-shaped block 73 arranged on the inner wall of the contact cylinder 72 will squeeze the wedge-shaped frame 76, and the wedge-shaped frame 76 will slide horizontally in the fixed seat 71. When the wedge-shaped frame 76 slides horizontally, it will drive the wedge-shaped lifting frame 74 to lift upward. The lifting frame 74 moves upward and drives the tray 77 to move upward. The four lifting rods 78 arranged on the tray 77 will drive the grinding disc 15 to move upward.

8. A method for using a fire extinguisher cover deburring device, using the fire extinguisher cover deburring device as claimed in any one of claims 1 to 7, characterized in that: The method comprises the following steps: S1: When the upper cover of the fire extinguisher is polished, the fire extinguisher is placed in the placement groove (12) in the processing table (11), the bottom of the fire extinguisher corresponds to the polishing disc (15) in the placement groove (12), and the support frame (14) is moved toward the placement groove (12) under the drive of the screw slide (13). At this time, the clamping device (4) is in a retracted state, and the clamping device (4) penetrates from the top opening of the upper cover of the fire extinguisher to the inner wall of the fire extinguisher. At this time, the driving motor (21) rotates, and the driving motor (21) drives the screw (22) to rotate. The two ends of the moving frame (31) do not contact the supporting disc (24) and the supporting frame (14), and then the contact block (33) moves toward the limiting groove (27) in the rotating cylinder (26) under the restriction of the pressure spring (35). The contact block (33) is in contact with the limiting groove (27) on the rotating cylinder (26). In the clamping state, when the screw rod (22) rotates, the limiting groove (27) on the rotating cylinder (26) is limited by the abutment block (33), and the rotating cylinder (26) and the screw rod (22) are screwed together to enable the rotating cylinder (26) to move vertically downward. After the rotating cylinder (26) moves vertically downward, the rotating cylinder (26) drives the outer sleeve (42) to move downward. Due to the magnetic attraction between the bottom of the positioning sleeve (41) and the magnetic attraction block (47), the positioning sleeve (41) can be limited on the magnetic attraction block (47). When the outer sleeve (42) moves downward, the connecting frame (44) arranged on the outer sleeve (42) drives the telescopic rod (45) to expand outward. At this time, the clamping plate (46) on the telescopic rod (45) contacts the inner wall of the upper cover of the fire extinguisher, thereby limiting the position of the fire extinguisher, so that the polished end surface of the fire extinguisher can be fully polished. S2: When the clamping plate (46) is expanded to the maximum range, the movable frame (31) will contact the surface of the carrier plate (24), and the movable frame (31) will slide in the limiting frame (25). When the limiting frame (25) slides, the V-shaped slide groove (32) on the limiting frame (25) will drive the clamping rod (36) on the resistance block (33) to move, thereby separating the resistance block (33) from the limiting groove (27) on the rotating cylinder (26). When the rotating cylinder ( 26) When there is no restriction of the abutment block (33), the rotation of the screw rod (22) will drive the rotating cylinder (26) to rotate, and the rotation of the rotating cylinder (26) will drive the outer sleeve (42) to rotate, and the rotation of the outer sleeve (42) will drive the positioning sleeve (41) to rotate synchronously through the provided clamping frame (48). At this time, the outer sleeve (42) and the positioning sleeve (41) rotate synchronously, thereby driving the clamped fire extinguisher cover to rotate in the placement groove (12); S3: After the clamping device (4) clamps the inner wall of the upper cover of the fire extinguisher, the outer sleeve (42) rotates to drive the small gear ring (53) that is connected to the outer sleeve to rotate. The rotation of the small gear ring (53) drives the large gear ring (52) to rotate slowly. The large gear ring (52) drives the sliding plate (61) to move through the arc groove (54). When the sliding plate (61) moves, the hinge frame (68) connected between the sliding plate (61) and the sliding frame (67) will deflect. The deflection of the hinge frame (68) will drive the rotating rod (63) to rotate. The rod (63) drives the rotating gear (64) to move the movable tooth plate (65) toward the outer wall of the fire extinguisher. When the clamping device (4) clamps and rotates the upper cover of the fire extinguisher, the sliding plate (61) moves so that the grinding block (66) close to the center of the upper cover of the fire extinguisher gradually moves toward the outer edge of the fire extinguisher. The movable tooth plate (65) is driven by the rotating gear (64) to gradually move downward, so that the grinding block (66) on the movable tooth plate (65) moves toward the outer edge of the fire extinguisher and corresponds to the arc-shaped outer wall of the fire extinguisher. S4: After the fire extinguisher is polished, the driving motor (21) drives the screw rod (22) to rotate in the opposite direction. When the screw rod (22) rotates in the opposite direction, the movable frame (31) will not continue to squeeze the outer wall of the bearing plate (24). Driven by the pressure spring (35), the abutment block (33) and the limiting groove (27) on the rotating cylinder (26) will be re-engaged. At this time, the rotation of the screw rod (22) will drive the outer sleeve (42) to move upward, thereby causing the clamping plate (46) in expansion to contract, so that the upper cover of the fire extinguisher can be taken out of the placement groove (12). After the upper movable frame (31) contacts the bearing frame (14), the abutment block (33) and the limiting groove (27) on the rotating cylinder (26) will be separated again. At this time, the rotating cylinder (26) drives the outer sleeve (42) to rotate, and the outer sleeve (42) causes the rotating disk (51) to rotate and reset. Driven by the rotating disk (51), the polishing member (6) is driven to reset. S5: When the clamping device (4) is unfolded outward, the outer sleeve (42) moves downward, which drives the clamping frame (48) to move downward. The bottom of the clamping frame (48) contacts the top of the abutment tube (72). The abutment tube (72) moves downward under the drive of the clamping frame (48). When the abutment tube (72) moves downward, the wedge-shaped clamping block (73) arranged on the inner wall of the abutment tube (72) presses the wedge-shaped frame (76). The wedge-shaped frame (76) slides horizontally in the fixing seat (71). When the wedge-shaped frame (76) slides horizontally, it drives the lifting frame (74) arranged in a wedge shape to lift upward. The lifting frame (74) moves upward, which drives the tray (77) to move upward. The four lifting rods (78) arranged on the tray (77) drive the grinding disc (15) to move upward.
