Description

TECHNICAL FIELD

[0001] The utility model belongs to a stator punching sheet processing frock, especially a kind of stacking frock for stator punching sheet welding. BACKGROUND

[0002] When the stator of motor is produced, the stator punching sheet is formed by punching one by one, then the stator punching sheet is stacked on the mold core, and after stacking to a certain height and quantity, it is welded on the corresponding welding machine, and the whole stack of stator punching sheet is pressed and welded to form the stator of motor. In actual workshop production, after the stacking and welding of the stator punching sheet with large volume, the whole stator needs to be taken out, but after the stator is pressed and welded, the whole stator is tightly attached to the outer wall of the mold core, so it is difficult to take out the whole stator directly upward. In order to take out the stator, the whole stator is gradually rotated upward on the mold core, and then slowly taken out, but during the rotating process, the efficiency of taking out the whole stator is affected, and at the same time, the welding points may be damaged, so that the gap between the stator punching sheets appears when taking out, thereby affecting the quality of the whole stator. SUMMARY

[0004] According to one aspect of the utility model, a kind of stacking frock for stator punching sheet welding is provided, including base, mold core, push plate and key, mold core is located on base, push plate is set in the outside of mold core, the outer periphery of mold core is equipped with slot, slot is multiple, and is evenly distributed on the outer periphery of mold core, slot is vertically arranged, key is inserted into slot, the outside of key is equipped with inclined guide rod, inclined guide rod is inclined to set, the outside end surface of inclined guide rod is higher than the outer periphery of mold core.

[0005] The utility model has the beneficial effects that: by being equipped with slot on the outside of mold core, when the stator punching sheet is placed, the key is inserted into the slot, because the inclined guide rod is arranged on the key, when the stator punching sheet is placed, the corresponding slot on the stator punching sheet is aligned with the inclined guide rod, the stator punching sheet is guided and stacked by the inclined guide rod, so that the stator punching sheet is formed into staggered stacking;When the stator punching sheet is welded, the whole stator is pushed out upward by push plate, the stator acts on the inclined guide rod, the stator and the whole key are vertically upward from the slot to realize unloading, the stator is unloaded conveniently, the unloading efficiency is improved, the whole stator is taken out vertically as a whole, and the welding quality of the stator is guaranteed.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Reference Figures 1-4 A stacking fixture for welding stator laminations includes a base 1, a die core 2, a pusher plate 3, and key 4. The die core 2 is mounted on the base 1, and the pusher plate 3 is sleeved on the outside of the die core 2. Multiple slots 21 are evenly distributed around the outer periphery of the die core 2, and the slots 21 are vertically arranged. The key 4 is inserted into the slot 21. An inclined guide rod 41 is provided on the outside of the key 4, and the inclined guide rod 41 is inclined with its outer end face higher than the outer periphery of the die core 2. The inclined guide rod 41 and the key 4 are integrally formed. There can be two, three, or four slots 21, all evenly distributed around the outer periphery of the die core 2, with each key 4 corresponding to a slot 21.

[0021] In actual production, a cylinder is installed on the outside of the tooling. The piston rod of the cylinder acts on the pusher plate 3, and the pusher plate 3 moves up and down by the lifting and lowering of the piston rod. When the cylinder pushes the pusher plate 3 upward, the pusher plate 3 can push out the stator sleeved on the mold core 2.

[0022] When stator laminations (such as...) Figure 5 (As shown) When stacking welding is required, the pusher plate 3 descends to its lowest position, inserting the key 4 into the slot 21. Subsequently, stator laminations are fitted one by one onto the mold core 2, with the corresponding slots on the inner side of the stator laminations aligned with the inclined guide rod 41. Due to the inclined setting of the inclined guide rod 41, the stator laminations gradually achieve misalignment during stacking, meeting the stacking requirements of the stator. After the stator laminations are stacked, a pressure block can be pressed down on top of the entire stack of stator laminations to press them tightly and prevent excessive gaps between the stator laminations. Subsequently, the stator laminations can be welded by welding equipment to form the stator. After welding, the pusher plate 3 moves upward, pushing the stator upward. As the stator moves upward, due to the inclined setting of the inclined guide rod 41, the key 4 can be moved upward synchronously, and the key 4 and the stator are pushed out by the pusher plate 3 together. Because of the key 4 and the inclined guide rod 41, it is convenient for the pusher plate 3 to push the stator upward directly without having to rotate the stator for unloading.

[0023] The stator punching sheet welding stacking tool also comprises a reverse sleeve 5, the reverse sleeve 5 is sleeved outside the mold core 2, the reverse sleeve 5 is located above the base 1, and the outer diameter of the reverse sleeve 5 is greater than the inner diameter of the pushing plate 3.

[0024] The stator punching sheet welding stacking tool also comprises a high pad 6, the high pad 6 is sleeved outside the mold core 2, the high pad 6 is located above the reverse sleeve 5, the bottom end of the high pad 6 is in abutment with the reverse sleeve 5, and the pushing plate 3 is located above the high pad 6. In actual use, the height of the high pad 6 can be adjusted according to the size requirement of the stator, when the height of the stator is relatively small, the high pad 6 with a relatively high height can be selected, so that the position of the pushing plate 3 is correspondingly adjusted, thereby the number of stator punching sheets sleeved on the mold core 2 can be reduced, and different use requirements can be met.

[0025] The outer diameter of the pushing plate 3 is greater than the outer diameter of the high pad 6 and the outer diameter of the reverse sleeve 5. Therefore, the external cylinder can act on the pushing plate 3.

[0026] The outer side surface of the plug key 4 is flush with the outer peripheral surface of the mold core 2.

[0027] The pushing plate 3 comprises a limiting portion 31 and a pushing portion 32, the limiting portion 31 is located above the pushing portion 32, and the outer diameter of the pushing portion 32 is greater than the outer diameter of the limiting portion 31. The pushing portion 32 is welded and fixed below the limiting portion 31, and the inner side wall of the pushing portion 32 does not contact the mold core 2; the inner diameter of the pushing portion 32 is greater than the inner diameter of the limiting portion 31, so that the contact area of the pushing plate 3 and the mold core 2 is reduced.

[0028] The inner wall of the limiting portion 31 is provided with a groove 311, the groove 311 corresponds to the inclined guide rod 41, and the inclined guide rod 41 is located in the groove 311. The outer diameter of the limiting portion 31 is consistent with the outer diameter of the stator punching sheet, and the limiting portion 31 can support the stator punching sheet.

[0029] The outer wall of the limiting portion 31 is provided with a plurality of notches 312. The plurality of notches 312 facilitate the external welding equipment to weld the stator punching sheet at the notches 312, and the number of the notches 312 can be adjusted according to the specific welding requirement.

[0030] A plurality of fixing holes 11 are arranged on the base 1, and the plurality of fixing holes 11 are uniformly distributed on the base 1. The fixing holes 11 facilitate the external bolts to be fixed through the fixing holes 11, so that the entire base is fixed and limited, the overall installation and fixation are facilitated, and the stator punching sheet is prevented from moving during welding.

[0031] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the inventive concept, a number of modifications and improvements can be made, and these all belong to the protection scope of the present application.
