[0010] Preferably, the two inner clamping members each include a push rod relative to the outer wall of the carrier frame, one end of the two push rods is connected to the inner clamping plate, and the other end of the two push rods away from the inner clamping plate is rotatably provided with a resistance wheel, which contacts the outer wall of the triangular push plate.

[0011] Preferably, the method for using the tooling for welding the chassis of a floor scrubber comprises the following steps: S1: When the left mounting beam and the right mounting beam are welded to the tooling bottom plate, the left mounting beam and the right mounting beam are respectively pressed against the inner walls on the left and right sides of the tooling bottom plate, and the driving disk is driven by the driving motor to rotate, and the rotating disk is driven by the belt to rotate, and the rotating disk rotates to rotate the spiral screw, and when the spiral screw rotates, the two moving blocks can be driven to move synchronously in opposite directions, and the clamping wheel on the moving block contacts the slide groove on the moving frame, and then when the moving block moves, the moving frame can be driven to deflect on the mounting frame by the moving block, and the other end of the moving frame away from the moving block will drive the external clamping device to move toward the outer wall of the tooling bottom plate, so that the two external clamping devices can clamp and limit the outer wall of the tooling bottom plate; S2: When the moving block drives the moving frame to move toward the outer wall of the tooling base plate, the two clamping frames on the moving frame will drive the clamping ring to make the clamping rod slide on the clamping tooling frame. At this time, the clamping rod will drive the outer clamping frame to move on the clamping tooling frame toward the outer wall of the tooling base plate. The outer clamping plate arranged on the outer clamping frame will abut against the outer wall of the clamping tooling frame. Driven by the pressure spring, the outer clamping plate is gradually subjected to force to clamp the outer wall of the clamping tooling frame. When the outer clamping frame moves toward the outer wall of the tooling base plate, the outer clamping plate conflicts with the outer wall of the tooling base plate. At this time, when the moving frame makes the clamping rod continue to move toward the direction of the tooling base plate through the clamping frame, the outer clamping plate will squeeze the pressure spring, thereby causing the outer clamping plate to slide on the outer clamping frame. At this time, the outer clamping plate will drive the moving toothed plate to move on the outer clamping frame, and the moving toothed plate will drive the rotating gear to rotate. The rotation of the rotating gear drives the rotating rod to rotate, and the rotating rod drives the first bevel gear to rotate to cause the second bevel gear to rotate. The second bevel gear is engaged with the clamping rod, and then the clamping rod can be rotated under the drive of the second bevel gear. The rotation of the clamping rod will drive the rotating toothed disk to rotate. The rotation of the rotating toothed disk will drive the sliding toothed plate to move on the mounting frame, and the calibration plate arranged at the bottom of the sliding toothed plate will press toward the bottom of the left mounting beam, and move along one end of the left mounting beam toward the other end, thereby causing the outer clamping device to clamp the outer wall of the tooling base plate; S4: After the outer clamping plate clamps the outer wall of the tooling bottom plate, the first bevel gear drives the second bevel gear to rotate. When the second bevel gear rotates the clamping rod, the clamping rod drives the one-way bearing to rotate. The rotation of the one-way bearing rotates the transmission disc. The rotation of the transmission disc drives the articulated frame to move, which pulls the pressing plate downward. The pressing plate drives the pressing rod to contact the top of the pushing frame. At this time, the pushing frame will move downward. When the pushing frame moves downward, it will synchronously drive the positioning column in the pushing frame to move downward. The rectangular stopper on the positioning column will pass through the rectangular groove on the bearing frame. When the rectangular stopper contacts the bottom surface of the bearing frame, the positioning column will slide in the pushing frame. The positioning rod will cause the positioning column to rotate under the restriction of the slot, and the rectangular stopper arranged at the bottom of the positioning column will be a gap between the rectangular slots, thereby limiting the pushing frame on the load-bearing frame and preventing the pushing frame from moving up and resetting under the action of the reset spring. Then, after the transmission disc rotates one circle, it drives the pressure rod to move up and reset. At this time, the pushing frame is under the load-bearing frame, and the triangular push plates arranged on both sides of the pushing frame will contact the resistance wheels, thereby causing the resistance wheels to be squeezed and drive the pushing rod to move so that the inner clamping plate clamps the left mounting beam and the right mounting beam. The inner walls of the left mounting beam and the right mounting beam are tightly attached to the inner wall of the tooling bottom plate, which is convenient for welding and fixing the calibrated left mounting beam and the right mounting beam. S5: After the left mounting beam and the right mounting beam are welded and fixed to the tooling base plate, the push frame can be pushed by the electric push rod. When the push frame moves, the rectangular block will contact the carrier frame again, and the positioning rod on the positioning column will rotate again under the restriction of the slot. The rectangular block corresponds to the rectangular slot, and the push frame can be moved up and reset under the drive of the reset spring, thereby releasing the clamping operation of the left mounting beam and the right mounting beam.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when the moving block moves, the moving frame can be deflected on the mounting frame under the drive of the moving block, and the other end of the moving frame away from the moving block will drive the external clamping device to move toward the outer wall of the tooling base plate, so that the two external clamping devices can clamp and limit the outer wall of the tooling base plate, and after the tooling base plate is welded and fixed to the left mounting beam and the right mounting beam, the tooling base plate can be moved as a whole to the bottom of the floor scrubber by clamping the mechanical wall of the peripheral device on the top of the tooling frame, so that the floor scrubber is conveniently connected and fixed to the tooling base plate.

[0013] In the present invention, when the moving block drives the moving frame to move toward the outer wall of the tooling base plate, the two clamping frames on the moving frame will drive the clamping ring to make the clamping rod slide on the clamping frame. At this time, the clamping rod will drive the outer clamping frame to move on the clamping frame toward the outer wall of the tooling base plate, and the outer clamping plate arranged on the outer clamping frame will abut against the outer wall of the clamping frame. Driven by the pressure spring, the outer clamping plate is gradually subjected to force to clamp the outer wall of the clamping frame, thereby realizing the limiting operation of the clamping frame, which is convenient for the subsequent installation of the left mounting beam and the right mounting beam on the clamping frame, and stable welding can be achieved.

[0014] In the present invention, when the external clamping device clamps the outer wall of the tooling base plate, the two auxiliary calibration devices can press the bottom of the left mounting beam and the right mounting beam respectively, so that the top of the left mounting beam and the right mounting beam are arranged parallel to the side wall of the tooling base plate, thereby avoiding position deviation when the left mounting beam and the right mounting beam are welded to the tooling base plate.

[0015] In the present invention, after the left mounting beam and the right mounting beam are welded and fixed to the tooling bottom plate, the pushing frame can be pushed by the electric push rod. When the pushing frame moves, the rectangular stopper will contact the supporting frame again, and the positioning rod on the positioning column will rotate again under the restriction of the card slot. The rectangular stopper corresponds to the rectangular slot, so that the pushing frame can be moved up and reset under the drive of the reset spring, thereby releasing the clamping operation of the left mounting beam and the right mounting beam, so that the operator can observe the welding condition of the left mounting beam and the right mounting beam and make adjustments thereto.

[0016] In the present invention, the unlocking is controlled by the outer clamping device and the inner clamping device respectively, so that the operator can directly move the tooling bottom plate after observing the welding conditions of the left mounting beam and the right mounting beam, which makes it more convenient for the operator to install the scrubber later.

When the left mounting beam 11 and the right mounting beam 12 are attached to the tooling bottom plate 1 After being welded and fixed, the push frame 62 can be pushed by the electric push rod 63. When the push frame 62 moves, the rectangular stopper 69 will contact the carrier frame 61 again, and the positioning rod 68 on the positioning column 67 will rotate again under the restriction of the card slot 66. The rectangular stopper 69 corresponds to the rectangular slot 610, so that the push frame 62 can be moved up and reset under the drive of the reset spring 64, thereby releasing the clamping operation of the left mounting beam 11 and the right mounting beam 12, so that the operator can observe the welding conditions of the left mounting beam 11 and the right mounting beam 12, and adjust them accordingly; At this time, the outer clamping device 3 is still in the state of clamping the tooling base plate 1, so the tooling base plate 1 after welding can be moved to the installation position of the floor scrubber under the drive of the robot arm, so as to facilitate the movement of the tooling base plate 1. The outer clamping device 3 and the inner clamping device 6 are respectively controlled to unlock, so that the operator can observe the welding conditions of the left mounting beam 11 and the right mounting beam 12, and then directly move the tooling base plate 1, which is more convenient for the operator to install the floor scrubber later.

[0025] The use method and advantages of the present invention: The use method of the tooling for welding the chassis of a floor scrubber, the working process is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown: S1: When the left mounting beam 11 and the right mounting beam 12 are welded to the tooling base plate 1, the left mounting beam 11 and the right mounting beam 12 are respectively pressed against the inner walls on the left and right sides of the tooling base plate 1, and the driving disc 24 is rotated under the drive of the driving motor 21, and the rotating disc 23 is driven to rotate by the belt 25. The rotation of the rotating disc 23 causes the spiral screw 22 to rotate. When the spiral screw 22 rotates, it can respectively drive the two moving blocks 26 to move synchronously in the opposite direction, and the clamping wheel 28 on the moving block 26 contacts the slide groove 210 on the moving frame 29. Then, when the moving block 26 moves, the moving frame 29 can be deflected on the mounting frame 14 under the drive of the moving block 26, and the other end of the moving frame 29 away from the moving block 26 will drive the outer clamping device 3 to move toward the outer wall of the tooling base plate 1, so that the two outer clamping devices 3 can clamp and limit the outer wall of the tooling base plate 1; S2: When the moving block 26 drives the moving frame 29 to move toward the outer wall of the tooling base plate 1, the two clamping frames 33 on the moving frame 29 will drive the clamping ring 32 to make the clamping rod 31 slide on the clamping tooling frame 13. At this time, the clamping rod 31 will drive the outer clamping frame 34 to move on the clamping tooling frame 13 toward the outer wall of the tooling base plate 1. The outer clamping plate 35 arranged on the outer clamping frame 34 will abut against the outer wall of the clamping tooling frame 13. Driven by the pressure spring 37, the outer clamping plate 35 is gradually subjected to force to clamp the outer wall of the clamping tooling frame 13. S3: When the outer clamping frame 34 moves toward the outer wall of the tooling base plate 1, the outer clamping plate 35 contacts the outer wall of the tooling base plate 1. At this time, when the moving frame 29 makes the clamping rod 31 continue to move toward the tooling base plate 1 through the clamping frame 33, the outer clamping plate 35 will squeeze the pressure spring 37, thereby making the outer clamping plate 35 slide on the outer clamping frame 34. At this time, the outer clamping plate 35 will drive the moving tooth plate 43 to move on the outer clamping frame 34, and the moving tooth plate 43 will drive the rotating gear 42 to rotate. The rotation of the rotating gear 42 drives the rotating rod 41 to rotate, and the rotating rod 4 1 drives the first bevel gear 44 to rotate so as to rotate the second bevel gear 45, and the second bevel gear 45 is engaged with the clamping rod 31, so that the clamping rod 31 can be rotated under the drive of the second bevel gear 45, and the rotation of the clamping rod 31 will drive the rotating toothed disc 46 to rotate, and the rotation of the rotating toothed disc 46 will drive the sliding toothed plate 47 to move on the mounting frame 14, and the calibration plate 48 provided at the bottom of the sliding toothed plate 47 will press toward the bottom of the left mounting beam 11, and move along one end of the left mounting beam 11 toward the other end, so that the outer clamping device 3 clamps the outer wall of the tooling bottom plate 1; S4: After the outer clamping plate 35 clamps the outer wall of the tooling base plate 1, the first bevel gear 44 drives the second bevel gear 45 to rotate. When the second bevel gear 45 rotates the clamping rod 31, the clamping rod 31 drives the one-way bearing 52 to rotate. The rotation of the one-way bearing 52 causes the transmission disc 51 to rotate. The rotation of the transmission disc 51 drives the articulated frame 54 to move, which pulls the pressing plate 53 downward. The pressing plate 53 drives the pressing rod 55 to contact the top of the pushing frame 62. At this time, the pushing frame 62 will move downward. When the pushing frame 62 moves downward, it will synchronously drive the positioning column 67 in the pushing frame 62 to move downward. The rectangular stopper 69 on the positioning column 67 will pass through the rectangular groove 610 on the supporting frame 61. When the rectangular stopper 69 contacts the bottom surface of the supporting frame 61, the positioning column 67 will slide in the pushing frame 62. The positioning rod 68 will make the positioning column 67 rotate under the restriction of the slot 66, and the rectangular stopper 69 arranged at the bottom of the positioning column 67 will be a gap between the rectangular slots 610, thereby limiting the push frame 62 on the carrier frame 61 and preventing the push frame 62 from moving up and resetting under the action of the reset spring 64. Then, after the transmission disc 51 rotates one circle, it drives the pressure rod 55 to move up and reset. At this time, the push frame 62 is under the carrier frame 61, and the triangular push plates 611 arranged on both sides of the push frame 62 will contact the contact wheel 73, so that the contact wheel 73 is squeezed and drives the push rod 71 to move so that the inner clamping plate 72 clamps the left mounting beam 11 and the right mounting beam 12. The inner walls of the left mounting beam 11 and the right mounting beam 12 are tightly attached to the inner wall of the tooling bottom plate 1, which is convenient for welding and fixing the calibrated left mounting beam 11 and the right mounting beam 12. S5: After the left mounting beam 11 and the right mounting beam 12 are welded and fixed to the tooling base plate 1, the pushing frame 62 can be pushed by the electric push rod 63. When the pushing frame 62 moves, the rectangular stopper 69 will contact the supporting frame 61 again, and the positioning rod 68 on the positioning column 67 will rotate again under the restriction of the card slot 66. The rectangular stopper 69 corresponds to the rectangular slot 610, so that the pushing frame 62 can move up and reset under the drive of the reset spring 64, thereby releasing the clamping operation of the left mounting beam 11 and the right mounting beam 12.
