Description

Technical Field

[0001] The utility model relates to a motor assembly line, in particular to an elevator motor assembly line. Background Art

[0002] When assembling the elevator motor (traction machine), it is necessary to assemble the yoke, stator, bearing and other components. After assembly, wiring, torque test and noise test are performed. However, at present, the assembly is performed on different equipment. After assembly, the assembly is carried out to the corresponding work station by a manipulator or a lifting mechanism for assembly and testing. The assembly efficiency is low and the cost is high. Some current motor assembly lines, such as the permanent magnet motor assembly production line disclosed on November 23, 2018, with the publication number CN108880134A, cannot perform torque testing. In addition, when installing the yoke, stator and bearing of the elevator motor, the yoke is vertical to the ground as a whole. After assembling it, during wiring, torque test and noise test, the motor needs to be laid down as a whole (i.e. parallel to the ground) according to the process requirements. The disclosed motor assembly line is not suitable for the assembly of the elevator motor, and once the motor is laid down as a whole, the operating position is lowered as a whole. When manual operation is required, it is not conducive to the operation of the operator. Utility Model Content

[0035] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0036] See also Figure 1 As shown, this embodiment discloses an elevator motor assembly line, including an assembly line body 10A and a test line body 10B connected end to end, the assembly line body 10A is used to assemble the elevator motor, and the test line body 10B is used to perform wiring test on the elevator motor. In this embodiment, the assembly line body 10A and the test line body 10B are distributed in a straight line.

[0037] The assembly line 10A of the present embodiment is provided with a heating station 10-1, a bearing press-fitting station 10-2, a stator press-fitting station 10-3, and a plurality of manual assembly stations 10-4 in sequence. The heating station 10-1 is used to heat the yoke. After the bearing is heated externally, it is placed in the press of the bearing press-fitting station 10-2 to press-fit the bearing and the yoke. After moving to the stator press-fitting station 10-3, the stator is press-fitted by a press or manually, and then moved to a plurality of manual assembly stations 10-4 to install other components of the elevator motor respectively until the elevator motor is assembled. When the elevator motor product is assembled on the assembly line 10A, it is in a standing state.

[0038] The test line 10B of this embodiment is provided with a flip waiting station 10-5, a rotation wiring station 10-6, a rotation reset station 10-7, a torque test station 10-8, and a noise test station 10-9 in sequence. The manual assembly station 10-4 at the end and the flip waiting station 10-5 are flipped 90 degrees by a hoisting machine. The elevator motor product on the flip waiting station 10-5 is placed horizontally, and its length direction is consistent with the length direction of the test line 10B. The rotation wiring station 10-6 is used to rotate the elevator motor 90 degrees, and the two ends of the elevator motor placed horizontally (horizontally) face the two sides of the assembly line. The operator can connect the wires on the outside of the test line; after the connection, they enter the torque test station 10-8 and the noise test station 10-9 respectively, and perform torque and noise tests on them in turn.

[0039] like Figure 2 As shown, the test line 10B in this embodiment is higher than the assembly line 10A. Since the elevator motor on the test line 10B is placed horizontally, its height is reduced. The test line 10B is set higher than the assembly line 10A to facilitate the operation of the operators and reduce the fatigue of the operators.

[0040] The assembly line 10A and the test line 10B both include a product conveying speed chain 11 and a jig return speed chain 12 which are arranged in parallel up and down and are used to convey the jig plate 70; a jig lifting and reflow machine 20 for reflowing the jig is arranged between the assembly line 10A and the test line 10B and at the head end of the assembly line 10A and the end of the test line 10B; since the assembly line 10A and the test line 10B are at different heights, the jig plate 70 of the product conveying speed chain 11 of the assembly line 10A circulates independently, and the jig plate 70 of the jig return speed chain 12 also circulates independently, and the jig plates on the assembly line 10A and the test line 10B share the jig lifting and reflow machine 20 therebetween, thereby reducing the investment in the jig lifting and reflow machine 20 and reducing the equipment cost, and the upper and lower arrangements reduce the floor space occupied by the assembly line.

[0041] In order to protect the product conveying speed chain 11 in this embodiment, a lifting device for lifting the jig plate 70 to a position higher than the product conveying speed chain 11 is provided between the bearing press-fitting station 10-2, the stator press-fitting station 10-3, the torque test station 10-8, and the noise test station 10-9.

The blocking member 30 is driven by the blocking member cylinder 31 to rise to a position higher than the product conveying speed chain 11. Setting each station to the same size is conducive to the installation of the position of the blocking member 30.

[0043] The lifting device of the rotary wiring station 10-6, the rotary reset station 10-7, the torque test station 10-8, and the noise test station 10-9 in this embodiment is a lifting and rotating device 40, such as Figure 4 As shown, the lifting and rotating device 40 includes a first lifting plate 41 arranged between a pair of product conveying speed chains 11, and a driven gear 42 and a driving gear 43 that mesh with each other are rotatably arranged on the first lifting plate 41.

The driven gear 42 is located below the fixture plate 70 on the corresponding product conveying speed chain 11. The driving gear 43 is driven to rotate by a gear motor 44. A lifting cylinder 45 is arranged at the bottom of the first lifting plate 41, and the lifting cylinder 45 is used to drive the first lifting plate 41 to rise above the product conveying speed chain 11. When the elevator motor is transported by the product conveying speed chain 11 to any of the rotating wiring station 10-6, the rotating reset station 10-7, the torque test station 10-8, and the noise test station 10-9, the lifting cylinder 45 drives the first lifting plate 41 to rise, driving the gear motor 44, the driving gear 43, and the driven gear 42 on the first lifting plate 41 to rise together, and the jig plate 70 on the product conveying speed chain 11 corresponding to the driven gear 42 is lifted up, and at this time, the jig plate 70 is separated from the product conveying speed chain 11; the gear motor 44 on the first lifting plate 41 drives the driving gear 43, and then drives the driven gear 42 to rotate, and finally drives the jig plate 70 corresponding to the product conveying speed chain 11 to rotate, and after pressing and testing, the lifting cylinder 45 is reset, and the jig plate 70 falls to the product conveying speed chain 11 again, and is transported to the next station by the product conveying speed chain 11. The size of the driving gear 43 in this embodiment is smaller than the size of the driven gear 42.

[0044] The lifting device of the bearing press-fitting station 10-2 is a side push lifting device 50, such as Figure 5As shown, the side-pushing and lifting device 50 includes an active rack 51, a driven rack 52, and a second lifting plate 53. The driven rack 52 is fixed at the bottom of the second lifting plate 53 and is located above the active rack 51. The facing end surfaces of the active rack 51 and the driven rack 52 are provided with isosceles trapezoidal tooth structures of the same shape, and the tooth structures can mesh with each other. One side of the driven rack 52 is connected and fixed to the translation cylinder 54. The translation cylinder 54 drives the driven rack 52 to move back and forth, thereby driving the active rack 51 and the second lifting plate 53 thereon to rise and fall. The second lifting plate 53 is located below the jig plate 70 on the corresponding product conveying speed chain 11. A matching second guide sleeve 55 and a second guide column 56 are provided between the second lifting plate 53 and the frame 13 of the product conveying speed chain 11.

[0045] The translation cylinder 54 drives the active rack 51 to move horizontally back by side push and pull. When the two tooth structures are not engaged, the second lifting plate 53 is lifted up, and the jig plate 70 corresponding to the second lifting plate 53 is separated from the product conveying speed chain 11; when the two tooth structures are engaged with each other, the second lifting plate 53 descends, and the jig plate 70 corresponding to the second lifting plate 53 falls back onto the product conveying speed chain 11. The tooth structure is designed in an isosceles trapezoidal shape, which is convenient for the translation cylinder 54 to push.
