[0025] Figure 1-Figure 4The utility model discloses a welding tool for a new energy motor, which comprises a first limit assembly 10 and a second limit assembly 20 .
[0026] In this embodiment:
[0027] The first limiting assembly 10 includes a pressing block 11 and a plurality of limiting posts 12. The plurality of limiting posts 12 are vertically mounted on the pressing block 11 and are located below the pressing block 11. The pressing block 11 includes a first pressing block 111 and a second pressing block 112. The second pressing block 112 is mounted below the first pressing block 111 and contacts the motor core 30. The first pressing block 111 is provided with a second mounting hole 1111. The extension direction of the second mounting hole 1111 is in the same straight line as the extension direction of the first mounting hole 2111 of the second limiting assembly 20. In this embodiment, the outer diameter of the first pressing block 111 is greater than the outer diameter of the second pressing block 112.
[0028] The height of the limit column 12 can be adjusted, and the height H of the limit column 12 is H1-H2-H3, where H1 is the actual height of the stamped product, H2 is the theoretical height of the product, and H3 is the shrinkage height of the welded product. When calculating the actual height H1 of the stamped product, the product overlap coefficient and the difference in the same plate of the product are considered, and weight control is used, weight = product volume * silicon steel density; product theoretical height H2 = single piece thickness * theoretical number of pieces; when calculating the shrinkage height H3 of the welded product, it is stipulated that the shrinkage of the product within 100mm height is 1.5 material thicknesses, and for products greater than 100mm in height, the shrinkage of the product increases by 0.1 material thickness for every 10mm increase in height, where the material thickness is 0.25 to 0.3mm. Therefore, this application improves the overlap coefficient of the stator buckle point welding product and reduces the motor loss, while reducing the product deformation, and the product height and flatness meet the standards, eliminating these three customer complaints and improving product quality.
[0029] The second limiting assembly 20 includes a pressure plate 21, a limiting block 22, and a plurality of guide columns 23. The pressure plate 21 is used to place the motor core 30. The pressure plate 21 is arranged below the pressure block 11. The pressure plate 21 includes a pad 211 and a fixed plate 212. The pad 211 is installed on the fixed plate 212. The pad 211 is provided with a plurality of first mounting holes 2111 for mounting the guide columns 23.
[0030] In this embodiment, the outer diameter of the pad 211 is smaller than that of the fixing plate 212, and the first mounting hole 2111 is arranged on the outer periphery of the pad 211 and has a groove structure, so that the guide column 23 can be snap-fitted and installed in the groove, which is more convenient to operate.
[0031] The limit block 22 is installed on the pressure plate 21. The limit block 22 is provided with a plurality of protrusions 221. The plurality of protrusions 221 are arranged on the outer periphery of the limit block 22 along the radial direction of the limit block 22. One end of each limit column 12 abuts against a protrusion 221. In this embodiment, the number of protrusions 221 is 2 to 4, and at least two protrusions 221 are in a diameter direction of the limit block 22. The outer diameter of the pressure plate 21 is larger than the outer diameter of the limit block 22, and the protrusions 221 extend from the outer periphery of the limit block 22 to the outer peripheral edge of the pressure plate 21. The second limit assembly 20 is integrally formed, with low manufacturing difficulty and low cost.
[0032] One end of the guide post 23 is passed through the first mounting hole 2111, and the other end is passed through the second mounting hole 1111, and mainly plays a guiding role to prevent the first limit assembly 10 from being pressed off during the downward pressing process. In this embodiment, the number of guide posts 23 is greater than the number of limit posts 12. A plurality of guide posts 23 and a plurality of limit posts 12 are arranged on the second limit assembly 20 in a staggered manner and in parallel with each other.
[0033] In the present application, a plurality of limit columns 12 are arranged under the pressing block 11, so that when the stacked motor core 30 is pressed down by the welding configuration block with a heavier weight, the limit columns 12 can withstand a certain pressure, so that the motor core 30 is subjected to a relatively uniform force, ensuring that the stacking coefficient of the welding product is qualified and meets the stator stacking coefficient requirements of the new energy vehicle industry, and the product deformation is small, thereby improving product quality and meeting customer needs; the present application has low manufacturing difficulty and low production cost.
[0034] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications and improvements can be made, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the utility model, and all of them belong to the protection scope of the utility model.
