DETAILED DESCRIPTION

[0023] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0024] The term "multiple" as used herein refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0025] Figure 1 It is a schematic diagram of the overall structure of the new energy stator scissor external clamp provided in the embodiment of the present application. Figure 2 It is a schematic diagram of the installation of an elastic connector, which includes a rotating shaft 10, a connecting tube 20, an outer clamp sleeve 30 and a plurality of scissor clamp assemblies 40. The rotating shaft 10 can be connected to an external mechanical arm or a cylinder and other structures to control the transportation of the entire clamp. The connecting tube 20 is specifically designed as a cylindrical structure with one end open and the other end closed, and the closed end face is connected to the rotating shaft 10. The outer clamp sleeve 30 is sleeved on the bottom of the connecting tube 20 with an opening, and the inner diameter of the outer clamp sleeve 30 is not less than the outer diameter of the connecting tube 20, in order to realize the telescopic movement of the outer clamp sleeve 30.

[0026] See also Figure 2 , an elastic connector 50 is arranged in the connecting tube 20, one end of the elastic connector 50 is arranged inside the connecting tube 20, and the other end is fixed on the outer clamping sleeve 30. In particular, the outer clamping sleeve 30 is also arranged as a cylindrical structure with one end open and the other end closed, and the end with the opening is sleeved on the outside of the connecting tube 20, and the elastic connector 50 is fixedly connected to the closed end of the outer clamping sleeve 30. The scissor clamp assembly 40 is similar to a scissor structure, and its two scissor handles 41 are respectively installed on the outer tube wall of the connecting tube 20 and the outer clamping sleeve 30. When the outer clamping sleeve 30 is pressed upward by an external force to move the outer clamping sleeve 30 toward the connecting tube 20, the hinged scissor handles 41 will open or close, thereby grabbing the stator product. The pressure-applying component can be a cylinder piston or a motor shaft rod, etc., which applies pressure to the outer clamping sleeve 30 upward.

[0027] Figure 3 It is a partial exploded view of the new energy stator scissors outer clamp. A fixing sleeve 21 is fixedly installed on the outer wall of the connecting tube 20, and a plurality of mounting ears 22 hinged to the scissors handle 41 are arranged on the fixing sleeve 21 and the outer clamp sleeve 30. The structure of the mounting ears 22 is specifically related to the structure of the scissors handle 41. For example, when the hinged end of the scissors handle 41 is connected by a groove and a rotating shaft, the mounting ears 22 are arranged in pairs; when the hinged end of the scissors handle 41 is designed with an opening and a rotating shaft, the mounting ears 22 are arranged individually. In some embodiments, three groups of scissors clamp assemblies 40 are evenly arranged on the outer clamp sleeve 30 and the connecting tube 20, and the mounting ears are adjacent to each other by 120 degrees.

[0028] The elastic connector 50 includes a spring 51, a spring inner sleeve 52 and a mounting bolt 53. The spring inner sleeve 52 is clamped on the spring 51 and is specifically designed as a barrel cap shape. The straight barrel part is inserted into the center of the spring 51. The diameter of the brim structure is larger than the diameter of the spring 51 to ensure that it can be stuck between the surrounding spring wires. The mounting bolt 53 is threadedly connected to the spring inner sleeve 52, and then the mounting bolt 53 is fixedly installed to the outer clamping sleeve 30 to achieve the function of tension spring or compression spring. The spring 51 can be fixed on the closed end face at one end close to the connecting tube 20, or it can be not fixed. When not fixed, it is necessary to ensure that the outer clamping sleeve 30 will not completely slip off and cause the spring to detach from the inner cavity. The bottom end surface of the outer clamping sleeve 30 is provided with a mounting hole 31, and the mounting bolt 53 is passed through the mounting hole 31 and is arranged on the outer clamping sleeve 30, and is threadedly connected with the spring inner sleeve 52. Specifically, a nut can be set inside the outer clamping sleeve 30 to further fix it.

[0029] Figure 4 yes Figure 1 In the enlarged view of the center A, the scissors handle 41 is divided into a first scissors handle 42 and a second scissors handle 43. The first scissors handle 42 is rotatably connected to the handle body of the second scissors handle 43, for example, connected by a pin or a shaft at the center of the handle. The scissors handle can be a connecting rod of any structure or shape, for example Figure 4 The connecting rod is slotted, so that the second scissors handle 43 passes through the slot of the first scissors handle 42 and is connected by a pin. The connecting end of the handle is slotted, and the mounting ear 22 is set to the center of the slot, and then a pin is inserted to connect. The two ends of the first scissors handle 42 are rotatably connected to the outer clamp arm 44 and the fixed sleeve 21 respectively; the two ends of the second scissors handle 43 are rotatably connected to the outer clamp arm 44 and the outer clamp sliding sleeve 30 respectively. A linear slide hole 46 is provided on the outer clamp arm 44, and a slider 47 is provided in the linear slide hole 46. The first scissors handle 42 and the slider 47 are rotatably connected by a pin shaft. When the scissors handle is opened and closed, the clamp arm can be opened and closed by the linear slide hole 46 and the slider 47 provided on the outer clamp arm 44.

[0030] Considering the problem of unstable grasping of a circular stator, in this embodiment, an arc-shaped stator support block 45 is installed at the end of the outer clamping arm 44. The arc is consistent with the arc of the stator product, and a plurality of grooves 451 are provided in the stator support block 45 to improve the grasping force.

[0031] Figure 5It is a schematic diagram of the structure of the rotating shaft and the connecting cylinder in another embodiment. A bearing 11 is sleeved on the rotating shaft 10, and a bearing sleeve 12 is sleeved on the outside of the bearing 11 and the rotating shaft 10. The rotating shaft 10 itself can be connected to a motor or a rotating part to realize the rotation of the clamp itself. In the case where the rotating shaft 10 is long or heavy, a bearing can also be installed at the end of the connecting cylinder 20, and the bearing sleeve 12 is sleeved on the outside of the bearing. This part can realize the rotation of the clamp by rotating the rotating shaft when the bearing sleeve 12 is gripped externally. For the bottom of the outer clamp sleeve 30, it can be supported by a cylinder to achieve up and down extension. The use of the middle connecting bearing can make the force of the clamp act vertically on the product, avoiding displacement of the inner diameter iron core of the product, resulting in defective products and scrap.

[0032] In summary, the use of the connecting tube and the outer clamp sleeve can realize the telescopic opening and closing of the end of the scissor clamp assembly, and the setting of elastic parts in the inner cavity of the connecting tube and the outer clamp sleeve can realize the reset of the clamp. The scissor-type structure controls the support block vertically up and down to hold the outer diameter of the product, and the vertical clamping makes the product more concentric. The design of the rotating shaft can realize the rotation of the clamp as a whole. After setting the bearing and the bearing sleeve, it can be achieved that the force of the clamp can act vertically on the product to avoid displacement of the inner diameter core of the product, resulting in defective and scrapped.
