Detailed implementation manners

[0057] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0058] As Figure 1 shown, the integrated welding device for the left and right wall panels of a horizontal jack includes a base 101, a workbench 1, a turnover table, a slewing drive mechanism, a turnover drive mechanism, and a manipulator.

[0059] The workbench is rotatably positioned on a base (omitted in the figure) about a vertical axis. Three manipulators (welding manipulators) are arranged around the workbench. Four turnover platforms are evenly arranged on the workbench. The turnover platforms are rotatably positioned on the workbench. A rotary drive mechanism is used to drive the workbench to rotate unidirectionally ( Figure 8 in the counterclockwise direction) so that the turnover platforms sequentially pass by each manipulator for welding. A turnover drive mechanism is used to drive the turnover platforms to turn up and down so that the front and back sides of the left and right wall panels can be turned to the top surface of the workbench according to the welding requirements, thus cooperating with the welding of the manipulators.

[0060] The rotary drive mechanism includes a rotary motor 111 and a rotary speed reducer 112 that transmits the power of the rotary motor to drive the workbench to rotate. The turnover drive mechanism includes a turnover motor 113 and a turnover speed reducer 114 that transmits the power of the turnover motor to drive the turnover platform to rotate.

[0061] On the base 101, a shaft base 102 and three manipulator bases 103 are provided. The shaft base is fixed at the center of the base, and the manipulator bases are fixed around the shaft base. The workbench is rotatably positioned on the shaft base. The manipulators are fixed on the manipulator bases, and one manipulator is arranged on each base.

[0062] The workbench includes a rotating seat 104, a Y-shaped bracket 105, and a light-shielding frame. The rotating seat is rotatably positioned on the shaft base. The rotary drive mechanism is fixed on the rotating seat. Four Y-shaped brackets are respectively fixed on the side of the rotating seat, and the light-shielding frame is fixed on the top of the rotating seat.

[0063] The Y-shaped bracket includes a main arm 105.1 and two branches 105.2. The main arm 105.1 of the Y-shaped bracket is fixed to the rotating seat. The turnover platform is rotatably positioned on the branch 105.2 of the Y-shaped bracket. The turnover drive mechanism is provided on one of the branches of each Y-shaped bracket to drive the turnover platform to rotate. The adjacent two Y-shaped brackets are arranged at an angle of 90 degrees.

[0064] The light-shielding frame includes a central cover 106 and light-shielding plates 107. The central cover is fixed on the top of the rotating seat and surrounds the rotary drive mechanism on the rotating seat. Four light-shielding plates are fixed on the side of the central cover. The light-shielding plates are vertically arranged and are located above the horizontal plane of the turnover platforms. One light-shielding plate is arranged between every two turnover platforms. The adjacent two light-shielding plates are arranged at an angle of 90 degrees. The output shaft of the rotary speed reducer of the rotary drive mechanism is connected to the shaft base.

[0065] The flip table includes a flip frame 2, a bottom plate 3, and a positioning mechanism. The flip frame is rotatably positioned on the Y-shaped bracket through the rotating shafts 2.1 at both ends. The flip drive mechanism drives the flip frame to flip up and down so that one side of the left and right wall panels to be welded faces upward. The output shaft of the flip reducer of the flip drive mechanism is fixed to the rotating shaft of the flip frame. The rotation axes of two adjacent flip frames are perpendicular to each other, and the rotation axes of two symmetrically arranged (symmetrically arranged about the center of the workbench) are parallel to each other. A flip table is set between every two shading plates, which are used to shield the arc light when the robot is welding to protect the safety of workers.

[0066] The bottom plate is fixed to the turning frame, and two positioning mechanisms are arranged on the same bottom plate to fix a pair of wall panels and parts. Each positioning mechanism is used to fix one of the wall panels (left wall panel or right wall panel) and its corresponding parts (including the arm shaft hole reinforcement ring, the snap hole screw sleeve, the rear wheel frame, the front wheel shaft hole reinforcement ring, and the oil pump positioning plate).

[0067] The bottom plate is provided with a first operating hole 3.1 and a second operating hole 3.2. The first operating hole is close to the front end of the left and right wall panels, and is used to facilitate the operation of the robot when welding the front wheel axle hole reinforcement ring. The second operating hole is close to the rear end of the left and right wall panels, and is used to facilitate the operation of the robot when welding the oil pump positioning plate.

[0068] The positioning mechanism includes a first positioning component, a second positioning component, a third positioning component, a fourth positioning component, a fifth positioning component, and a sixth positioning component.

[0069] The first positioning assembly is used to fix the left wall panel or the right wall panel. In the first positioning assembly, the first base column 11 is fixed on the front side of the base plate, the first push rod 12 can be axially movably positioned in the first base column, the top end of the first push rod extends to the top of the first base column, the first push arm 13 is arranged above the first base column and is rotatably positioned at the top end of the first push rod, the upper part of the first push rod is provided with a groove for cooperating with the rotation of the first push arm, the first cylinder 14 is fixed on the reverse side of the base plate and the piston rod of the first cylinder passes through the base plate and is connected to the first push rod, the top head 15 is arranged on the front side of the base plate, the top head cylinder 16 is fixed on the reverse side of the base plate and the piston rod of the top head cylinder passes through the base plate and is connected to the top head.

[0070] The first positioning assembly includes three jacks, each of which is driven by a jack cylinder. The jack cylinder drives the jack to rise to support the reverse side of the left and right wall panels. The first pressing rod passes through the positioning holes 96 of the left and right wall panels and extends to the top of the left and right wall panels. The first pressing arm is moved to a horizontal position. The first cylinder drives the first pressing rod to descend and presses the front side of the left and right wall panels through the first pressing arm. Figure 17As shown in Figure b), the left and right wallboards are fixed by applying force from both sides through the cooperation of the top head and the first pressing arm. Moving the first pressing arm to the vertical position enables the first pressing arm and the first pressing rod to pass upward through the positioning holes of the left and right wallboards ( Figure 17 as shown in Figure a).

[0071] The second positioning component is used to fix the arm-lifting shaft hole reinforcing ring. In the second positioning component, the second bottom column 21 is fixed on the front surface of the bottom plate. The top surface of the second bottom column is provided with a convex platform for positioning the arm-lifting shaft hole reinforcing ring. The second pressing rod 22 is axially movably positioned in the second bottom column. The top end of the second pressing rod extends above the second bottom column. The second pressing arm 23 is arranged above the second bottom column and is rotatably positioned at the top end of the second pressing rod. A groove for cooperating with the rotation of the second pressing arm is provided in the upper part of the second pressing rod. The second air cylinder 24 is fixed on the reverse side of the bottom plate, and the piston rod of the second air cylinder passes through the bottom plate and then connects to the second pressing rod. The arm-lifting shaft hole reinforcing ring is placed on the front surfaces of the left and right wallboards and the convex platform of the second bottom column. Moving the second pressing arm to the horizontal position, the second air cylinder drives the second pressing arm to descend, so that the left and right wallboards and the arm-lifting shaft hole reinforcing ring are pressed tightly on the second bottom column for welding cooperation ( Figure 18 as shown in Figure b). Moving the second pressing arm to the vertical position enables the second pressing arm and the second pressing rod to pass upward through the arm-lifting shaft holes of the left and right wallboards and the arm-lifting shaft hole reinforcing ring ( Figure 18 as shown in Figure a).

[0072] The third positioning component is used to fix the press-button hole threaded sleeve. In the third positioning component, the third bottom column 31 is fixed on the front surface of the bottom plate. The top surface of the third bottom column is provided with a convex platform for positioning the press-button hole threaded sleeve. The third pressing rod 32 is axially movably positioned in the third bottom column. The top end of the third pressing rod extends above the third bottom column. The third pressing arm 33 is arranged above the third bottom column and is rotatably positioned at the top end of the third pressing rod. A groove for cooperating with the rotation of the third pressing arm is provided in the upper part of the third pressing rod. The third air cylinder 34 is fixed on the reverse side of the bottom plate, and the piston rod of the third air cylinder passes through the bottom plate and then connects to the third pressing rod. The press-button hole threaded sleeve is placed on the front surfaces of the left and right wallboards and the convex platform of the third bottom column. Moving the third pressing arm to the horizontal position, the third air cylinder drives the third pressing arm to descend, so that the left and right wallboards and the press-button hole threaded sleeve are pressed tightly on the third bottom column for welding cooperation ( Figure 18 as shown in Figure b). Moving the third pressing arm to the vertical position enables the third pressing arm and the third pressing rod to pass upward through the press-button holes of the left and right wallboards and the press-button hole threaded sleeve ( Figure 18 as shown in Figure a).

[0073] The fourth positioning component is used to fix the front wheel axle hole reinforcing ring. In the fourth positioning component, the fourth bottom column 41 and the fourth quick press head are fixed on the front surface of the bottom plate. The cantilever 3.3 extends into the first operation hole. The fourth bottom column is fixed at the front end of the cantilever. A boss for positioning the front wheel axle hole reinforcing ring is provided on the top surface of the fourth bottom column. The fourth quick press head 42 is arranged above the fourth bottom column. The fourth quick press head is fixed on the edge of the first operation hole through the fourth bracket 43. When the fourth quick press head presses down, the press head of the fourth quick press head presses on the front wheel axle hole reinforcing ring placed on the fourth bottom column and the left and right wall panels. The front wheel axle hole reinforcing ring is placed on the fourth bottom column, and the left and right wall panels are then placed on the front wheel axle hole reinforcing ring. Press the fourth quick press head to make the left and right wall panels fit tightly with the front wheel axle hole reinforcing ring for welding. The fourth quick press head is a prior art. The fourth quick press head is a push-pull type quick fixture.

[0074] The fifth positioning component is used to fix the rear wheel frame. In the fifth positioning component, the top plate 51 and the top plate cylinder 52 are arranged on the front surface of the bottom plate. The top plate cylinder is fixed on the edge of the second operation hole through the top plate bracket 53. The top plate cylinder is used to drive the top plate to move horizontally to position the rear wheel frame. When installing the left and right wall panels, the top plate cylinder retracts to leave a certain operation space. When positioning the rear wheel frame, the top plate cylinder extends. Place the rear wheel frame on the left and right wall panels. The rear wheel frame abuts against the top plate. The maximum distance at which the top plate cylinder extends is set as the welding position of the rear wheel frame. The length and width of the top plate fit the shape of the rear wheel frame. A magnet is also embedded in the top plate to attract the rear wheel frame, so that the top plate and the rear wheel frame fit tightly to ensure that the rear wheel frame does not move and achieve precise positioning.

[0075] The sixth positioning component is used to fix the oil pump positioning plate. The sixth positioning component includes a sixth quick press head 61 and a tooling plate 97. The sixth quick press head is arranged on the reverse side of the bottom plate and is fixed on the edge of the second operation hole through the sixth bracket 62. Figure 23 , Figure 24 , Figure 25 As shown, during use, insert the positioning post 98 of the tooling plate 97 into the oil pump installation hole 99 of the wall panel. Then place the oil pump positioning plate on the left and right wall panels. The oil pump positioning plate needs to be positioned close to the inverted L surface 100 of the tooling plate. Finally, press the sixth quick press head to tightly press and fix the oil pump positioning plate on the surface of the left and right wall panels. The sixth quick press head is a prior art. The sixth quick press head is a vertical type quick fixture.

[0076] An air switch 7 is also provided on the bottom plate. The air switch is arranged on the front surface of the bottom plate. The top head cylinder, the first cylinder, the second cylinder, the third cylinder, and the top plate cylinder are all connected to the air switch, and the air switch is then connected to an external air source.
