Description

Technical Field

[0001] This invention relates to the field of conical motor technology, and more particularly to a truss device for slotting silicon steel sheets in a conical motor. Background Technology

[0002] A conical rotor motor is a three-phase asynchronous motor with a conical stator and a conical rotor shaft, featuring a self-braking mechanism. In other words, both the stator's internal cavity and the rotor's external shape are conical. This type of motor has self-braking capability in the event of power failure and is commonly used in lifting equipment such as electric hoists and winches. my country is the world's largest production base for conical rotor motors, producing over 6 million units annually. Common power models include 0.4 / 0.5kW, 0.8 / 1.5kW, 2.2kW, 3.0 / 4.5kW, 7.5kW, and 13 / 18.5kW. Because the stator has a conical internal cavity and the rotor has a conical external shape, the silicon steel sheets in both the stator and rotor are stacked in a conical shape. The slots on the silicon steel sheets are also stacked in a conical shape, and the radial position of the slots on each silicon steel sheet is different. Taking a 0.4kW conical rotor motor as an example, both the stator and rotor are composed of 170 stacked silicon steel sheets, each with a thickness of 0.5mm. The stator's silicon steel sheets are all 120mm in diameter, with 24 slots evenly distributed around the circumference. The largest slot has an outer diameter of 104.5mm and an inner diameter of 76.5mm, while the smallest slot has an outer diameter of 95mm and an inner diameter of 67mm. The rotor's silicon steel sheets have 22 slots evenly distributed around the circumference. The diameter of the silicon steel sheet is the same as the radial diameter of the slot. The largest slot has an outer diameter of 76.5mm and an inner diameter of 56.1mm, while the smallest slot has an outer diameter of 67mm and a small diameter of 46.6mm.

[0003] Currently, the slotting process for silicon steel sheets is done manually, one by one, by removing them from the blank rack and placing them onto a CNC slotting machine. The CNC slotting machine operates at high speed, and after creating the stator and rotor slots, the sheets are manually removed and placed separately onto the stator and rotor racks. Taking a 0.4kW conical motor as an example, a worker needs to quickly and continuously pick up and place the silicon steel sheets 170 times, resulting in extremely high labor intensity. Furthermore, the high force of the CNC slotting machine easily injures the worker's fingers, and the loud noise can also damage their hearing. The working environment is extremely poor, and the processing efficiency is very low. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantages of high labor intensity, danger, poor working environment and low processing efficiency in the grooving process of silicon steel sheets.

This significantly reduces labor time and intensity, prevents injury to workers' fingers from the punching machine, minimizes hearing damage from punching noise, greatly improves the working environment, and increases production efficiency.

Then, the lifting cylinder in the lifting cylinder assembly descends, and simultaneously, the blank lamination loading chuck assembly 308 on the right side completes the adsorption of the blank laminations in process S2. S4: After the blank lamination loading chuck assembly 308 and the stator and rotor lamination unloading magnetic chuck assembly 301 have each completed the adsorption of the blank laminations and the slotted laminations of the stator and rotor,... Both sets of slide cylinders rise, then the first guide rail rodless cylinder 309 moves to the far left, the slide cylinder on the blank blank loading suction cup assembly 308 descends to place the blank blank into the blank suction lifting cylinder assembly 306 to complete the slotting, and the slide cylinder on the stator and rotor blank unloading magnetic suction cup assembly 301 descends to place the slotted blanks into the rotor blank unloading assembly 404; S5, after the blank blanks and the slotted blanks of the stator and rotor are placed, the slide cylinders of the stator and rotor blank unloading magnetic suction cup assembly 301 and the blank blank loading suction cup assembly 308 rise, and then the first guide rail rodless cylinder 309 moves to the far left. Figure 4 As shown, the rightmost step repeats the S3 process, while the second guide rail rodless cylinder 402 moves to... Figure 6 As shown on the far left, the stator and rotor laminations in the rotor lamination unloading assembly 404 are separated by the descending cylinder of the stator-rotor separation magnetic chuck assembly 412. The rotor laminations fall to the bottom via the rotor unloading guide post 405, simultaneously attracting the stator laminations to the electromagnet in the stator-rotor separation magnetic chuck assembly 412. After the cylinder of the stator-rotor separation magnetic chuck assembly 412 rises, the first guide rail rodless cylinder 309 moves to the far right, the cylinder of the stator-rotor separation magnetic chuck assembly 412 descends, the electromagnet is de-energized, and the stator laminations slide along the 404... The stator lamination blanking guide post 410 falls into the stator lamination blanking assembly 409; S6, the first guide rail rodless cylinder 309 and the second guide rail rodless cylinder 402 need to move left and right simultaneously to complete the S3 process, S4 process and S5 process, and repeat in sequence to complete the grooving of all laminations. After all laminations have been grooved, the workstation stops, and the stator laminations in the stator lamination blanking assembly 409 and the rotor laminations in the rotor lamination blanking assembly 404 are manually removed. Then, the blank laminations are placed in the blank lamination lifting rack 202.

[0036] This process is repeated, with the material being loaded and unloaded in a cyclical manner; the stator and rotor lamination unloading magnetic chuck assembly 301, the blank lamination loading chuck assembly 308, and the vertical plate 312 move synchronously towards... Figure 3When the movement is shown to the right, the two horizontal plates 603 move closer to each other, and the multiple bristles 604 on the two horizontal plates 603 do not contact the bottom and top of the punching die 501. Meanwhile, the stator and rotor lamination unloading magnetic chuck assembly 301, the blank lamination loading chuck assembly 308, and the vertical plate 312 move synchronously towards the right. Figure 3 When the device moves to the left as shown, the servo motor 605 rotates in the forward direction, driving the two toothed plates 607 to move up and down via the gear 606. This causes the two sliding plates 602 to move the two horizontal plates 603 away from each other, making the multiple bristles 604 flush with the bottom and top of the punching die 501. Subsequently, the stator and rotor blank unloading magnetic chuck assembly 301, the blank blank loading chuck assembly 308, and the vertical plate 312 move synchronously. Figure 3 When the left side moves as shown, multiple brush bristles 604 can clean the bottom and top of the grooving mold 501, removing impurities from its surface and preventing the presence of impurities from affecting the subsequent grooving quality of the silicon steel sheet.

Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
