Description

Technical Field

[0001] The utility model relates to the technical field of goods stacking and transportation, and particularly relates to a special pallet for stators that can be stacked. Background Art

[0002] In the process of handling stator workpieces, how to achieve neat stacking and transfer is a problem that needs to be overcome. Since stator workpieces are not regular geometric bodies, a special goods pallet that can achieve neat stacking needs to be designed.

[0003] The utility model patent with the application number 202322074607.1 authorized by the applicant before discloses a container unit stack, including a three-way pallet, a connecting pallet and a cavity pallet. The connecting pallet is arranged above the three-way pallet, and the cavity pallet is arranged above the connecting pallet. There is at least one cavity pallet, and the structures are the same and are stacked upward in sequence. An insertion channel for the forklift forks to insert is arranged below the three-way pallet, and cavity positions for accommodating goods are evenly distributed in an array on the cavity pallet. This utility model solves the problems of fixing and stacking stator workpieces by setting a pallet with cavities, but the main storage and fixing space lies in the connecting pallet. The following problems have occurred after the actual use of the existing connecting pallet:

[0004] 1. When stacking, the sides of the connecting pallets are completely attached to each other. Although it does not affect the manual separation and unloading by workers, the existing industrial robots cannot separate two connecting pallets through the manipulator, which affects the full automation transformation of logistics work;

[0005] 2. Due to the limitation of the injection molding process of the existing connecting pallet, only a large number of fine cavity structures can be set on one side of the pallet, and only one end of the stator can be limited, which affects the fixing effect;

[0006] 3. Since the existing connecting pallet is limited by a limiting structure with only a limiting groove formed by the gap between a mountain-shaped plastic boss and an inner support bar, the limiting strength is not high and the positioning is rather troublesome; therefore, there is room for further improvement. Summary of the Utility Model

[0007] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a special pallet for stators that can be stacked, which solves the above problems.

[0008] To achieve the above object, a special pallet for stackable stators is provided, including an upper disk body, a lower disk body and a stator main body. The upper disk body and the lower disk body are fixedly connected by a plurality of bolts. A plurality of lower concave cavities are arranged in an array on the upper surface of the upper disk body. Upper concave cavities are arranged at positions corresponding to the lower concave cavities on the lower surface of the lower disk body. An inner support frame is fixedly inlaid between the upper disk body and the lower disk body. Side grooves are opened at corresponding positions on the four sides below the upper disk body and the four sides above the lower disk body. Corner limit grooves are opened at the four corners of the upper disk body. Corner limit posts are arranged at positions corresponding to the four corner limit grooves below the lower disk body. Margin grooves are opened at the four corners above the lower disk body.

[0009] According to the special pallet for stackable stators, both the upper disk body and the lower disk body are integrally formed injection molded disk bodies.

[0010] According to the special pallet for stackable stators, when two pallets are stacked, one end above the stator main body is embedded in the upper concave cavity, and one end below the stator main body is embedded in the corresponding lower concave cavity.

[0011] According to the special pallet for stackable stators, a plurality of upper fixing bolt holes and upper hexagonal nut holes are respectively arranged on both sides of the upper disk body. Lower hexagonal nut holes are arranged at positions corresponding to the plurality of upper fixing bolt holes on the lower disk body. Lower fixing bolt holes are arranged at positions corresponding to the plurality of upper hexagonal nut holes on the lower disk body, so that the directions of the bolts for fixing both sides of the pallet are opposite, which can effectively prevent all the screws from loosening due to the vibration generated during the use of the pallet.

[0012] According to the special pallet for stackable stators, the shape of the corner limit groove is the same as that of the margin groove.

[0013] According to the special pallet for stackable stators, the shape of the corner limit post corresponds to the shape of the corner limit groove, and the length of the corner limit post corresponds to the sum of the heights of the corner limit groove and the margin groove.

[0014] The above solution has at least the following beneficial effects:

[0015] 1. By setting an upper disk body and a lower disk body respectively having upper and lower concave cavities, and cooperating with the fixing screws arranged in opposite directions on both sides, the present utility model forms a stable connection structure, which can form a limit pallet structure with both upper and lower concave cavities while avoiding the limitations of the injection molding process, improves the limiting ability for stators, and strengthens the practicability of the device.

[0016] 2. By setting side grooves on the four sides of the upper and lower disk bodies, the present utility model enables the overall four sides of the tray to have two pick-up slots for the robotic arm to extend into after the upper and lower disk bodies are combined, facilitating the pick-up by existing industrial robots, adapting to the full-automatic logistics transformation work, and enhancing the practicality of the device.

[0017] 3. The corner limit grooves provided at the four corners of the upper disk body of the present utility model, the surplus grooves and corner limit posts provided on the lower disk body, after the upper and lower disk bodies are combined, not only can be limited by the fitting of the limit posts and limit grooves with corresponding shapes, but also the settings in the corner areas facilitate the positioning during stacking, enhancing the practicality of the device.

[0027] Refer to Figures 1-4, an embodiment of the present utility model provides a stackable special pallet for a stator, which includes an upper disk body 1, a lower disk body 2 and a stator main body 3. Both the upper disk body 1 and the lower disk body 2 are integrally structured injection molded disk bodies. On both sides of the upper disk body 1, a plurality of upper fixing bolt holes 11 and upper hexagonal nut holes 12 are respectively provided. At positions corresponding to the plurality of upper fixing bolt holes 11 on the lower disk body 2, lower hexagonal nut holes 14 are provided. At positions corresponding to the plurality of upper hexagonal nut holes 12 on the lower disk body 2, lower fixing bolt holes 13 are provided. The upper disk body 1 and the lower disk body 2 are fixedly connected by a plurality of bolts. An inner support frame 6 is fixedly embedded between the upper disk body 1 and the lower disk body 2. By embedding the inner support frame 6 between the upper disk body 1 and the lower disk body 2, the situation of dislocation between the upper disk body 1 and the lower disk body 2 can be effectively prevented;

[0028] On the upper surface of the upper disk body 1, a plurality of lower concave cavities 4 are arranged in an array. At positions corresponding to the lower concave cavities 4 on the lower surface of the lower disk body 2, upper concave cavities 5 are provided. When two pallets are stacked, one end of the upper part of the stator main body 3 is embedded in the upper concave cavity 5, and one end of the lower part of the stator main body 3 is embedded in the corresponding lower concave cavity 4. By providing an upper disk body 1 and a lower disk body 2 with upper and lower concave cavities respectively, and cooperating with the fixing screws arranged in a positive and negative manner on both sides, a stable connection structure can be formed. Furthermore, under the condition of avoiding the limitations of the injection molding process, a limit pallet structure with upper and lower concave cavities can be formed, improving the limit ability for the stator;

[0029] At positions corresponding to the four sides of the lower part of the upper disk body 1 and the four sides of the upper part of the lower disk body 2, side grooves 7 are respectively opened. By arranging side grooves 7 on the four sides of the upper disk body 1 and the lower disk body 2, after the upper and lower disk bodies are combined, two pick-up slots for the robotic arm to extend into can be provided on the four sides of the whole pallet, facilitating the pick-up by the existing industrial robot and being used to adapt to the full-automatic logistics transformation work;

[0030] At the four corners of the upper disk body 1, corner limit grooves 8 are respectively opened. At positions corresponding to the four corner limit grooves 8 on the lower part of the lower disk body 2, corner limit posts 9 are provided. At the four corners of the upper part of the lower disk body 2, margin grooves 10 are respectively opened. The shape of the corner limit grooves 8 is the same as that of the margin grooves 10. The shape of the corner limit posts 9 corresponds to that of the corner limit grooves 8. The length of the corner limit posts 9 corresponds to the sum of the heights of the corner limit grooves 8 and the margin grooves 10. When the pallets are stacked, not only can the corner limit posts 9 and the corner limit grooves 8 with corresponding shapes be used for limiting by fitting, but also their arrangement in the corner area is convenient for positioning during stacking.

[0031] Working principle: The utility model forms a stable connection structure by arranging an upper disc body 1 and a lower disc body 2 each having upper and lower cavities, and cooperating with fixing screws arranged on both sides in a positive and negative manner. Furthermore, a limiting tray structure with upper and lower cavities can be formed while avoiding the limitations of the injection molding process, improving the limiting ability for the stator. By arranging side grooves 7 on the four sides of the upper disc body 1 and the lower disc body 2, after the upper and lower disc bodies are combined, two pick-up slots for the robotic arm to extend into are formed on the four sides of the overall tray, facilitating the pick-up by the existing industrial robots and adapting to the full-automatic logistics transformation work. When the trays are stacked, not only can the stacking be limited by the fitting of the corner limiting posts 9 and corner limiting grooves 8 with corresponding shapes, but the setting in the corner area also facilitates the positioning during stacking.
