Detailed implementation manners

[0028] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0029] Such as Figures 5-11A specific embodiment of a tooling for assembling elevator door hanging plates of multiple specifications according to the present invention is shown, including a tooling bottom plate 1. At both corners of the tooling bottom plate 1 near one of its long sides, roller placement seats 2 are provided. At both corners of the tooling bottom plate 1 near the other long side, hanger wheel placement seats 3 are provided. There are at least two roller placement grooves 21 for placing rollers 9 of different specifications in the roller placement seats 2, and there are at least two hanger wheel placement grooves 31 for placing hanger wheels 10 of different specifications in the hanger wheel placement seats 3. At least two hanging plate positioning pins 4 with different diameters are provided on the tooling bottom plate 1, and the diameter of the hanging plate positioning pins 4 is adapted to the hanger wheel mounting holes on the hanging plate body 8; A plurality of support blocks for supporting the hanging plate body 8 are also provided on the tooling bottom plate 1.

[0030] See Figure 6 , the tooling bottom plate 1 also has positioning holes for positioning and installing on the production line body, and a bushing 5 for the tooling positioning pin is provided in the positioning holes.

[0031] In this embodiment, a plurality of support blocks are provided. In order to avoid the "protruding" parts on the elevator door hanging plate, the support blocks are separated from each other, and a space for accommodating the "protruding" parts is formed between them. There are 13 support blocks in this embodiment, specifically: a first support block 61 and a second support block 62 are provided between the two roller placement seats 2. A third support block 63 and a fourth support block 64 are provided between the two hanger wheel placement seats 3. In the middle of the tooling bottom plate 1, a fifth support block 65, a sixth support block 66, a seventh support block 67, an eighth support block 68, a ninth support block 69, a tenth support block 610, an eleventh support block 611 and a twelfth support block 612 are arranged to form a square. At the long side edge of the tooling bottom plate 1 with the hanger wheel placement seat 3, a thirteenth support block 613 is provided.

[0032] Since the elevator door hanging plate needs to be flipped to the back to install the pulley 11 after the rollers 9 and hanger wheels 10 are installed, the sixth support block 66 and the twelfth support block 612 have folding edge placement grooves 7 for placing the folding edge 81 of the hanging plate body 8, so that better positioning of the elevator door hanging plate can be achieved.

[0033] In this embodiment, each roller placement seat 2 has two roller placement grooves 21, and each hanger wheel placement seat 3 has two hanger wheel placement grooves 31. Of course, in order to meet the assembly requirements of elevator door hanging plates of more specifications, more roller placement grooves 21 with different inner diameters can be provided in each roller placement seat 2, and more hanger wheel placement grooves 31 with different inner diameters can be provided in each hanger wheel placement seat 3.

[0034] Since the diameters of the mounting shafts of the product change gears 10 of different specifications are different, in this embodiment, two types of diameter hanger plate positioning pins 4 are provided. The hanger plate positioning pin 4 includes a first hanger plate positioning pin 41 provided at the long side edge and a second hanger plate positioning pin 42 provided between the roller placement seat 2 and the change gear placement seat 3 on the same side. The first hanger plate positioning pin 41 and the second hanger plate positioning pin 42 are staggered from each other to avoid interference when placing the hanger plate body 8.

[0035] The following combines the attached Figures 7-11 to give the assembly process of an elevator door hanger plate of one of the specifications:

[0036] See Figure 7 , first, the manipulator places the change gear mounting hole on the hanger plate body 8 on a suitable hanger plate positioning pin 4. In this embodiment, the hanger plate body 8 is placed on the first hanger plate positioning pin 41.

[0037] See Figure 8 , second, place the first change gear 10 in one of the change gear placement grooves 31 on the first change gear placement seat 32. Since both the change gear placement groove 31 and the first hanger plate positioning pin 41 have accurate position coordinates, the servo manipulator grabs the hanger plate body 8 and accurately moves it to the change gear placement groove 31. The mounting shaft of the first change gear 10 is inserted into the change gear mounting hole of the hanger plate body 8, and the hanger plate body 8 and the first change gear 10 are connected by a swaging head. The third support block 63, the fourth support block 64, and the thirteenth support block 613 effectively support the hanger plate body 8.

[0038] See Figure 9 , then, place the second change gear 10 in one of the change gear placement grooves 31 on the second change gear placement seat 33. The servo manipulator grabs the hanger plate body 8 and places it on the second change gear placement seat 33. The mounting shaft of the second change gear 10 is inserted into the change gear mounting hole of the hanger plate body 8, and the hanger plate body 8 and the second change gear 10 are connected by a swaging head. The third support block 63, the fifth support block 65, the sixth support block 66, and the twelfth support block 612 effectively support the hanger plate body 8.

[0039] See Figure 10 , then, place the first roller 9 in one of the roller placement grooves 21 on the first roller placement seat 22. The manipulator places the hanger plate body 8 on the first roller 9. The mounting shaft of the first roller 9 passes through the roller mounting hole 82 on the hanger plate body 8, and a gasket and a nut are placed and tightened to connect the roller 9 and the hanger plate body 8.

[0040] See Figure 11, finally, place the second roller 9 in one of the roller placement grooves 21 of the second roller placement seat 23. The manipulator places the hanging plate body 8 on the second roller 9, so that the mounting shaft of the second roller 9 passes through the roller mounting hole 82 on the hanging plate body, place the gasket and tighten the nut to connect the roller 9 and the hanging plate body 8.

[0041] It should be understood that the specific embodiments described above are only used to explain the present invention and are not used to limit the present invention. Obvious changes or variations derived from the spirit of the present invention are still within the protection scope of the present invention.
