[0009] The tightening member is arranged through the positioning hook and is threadedly connected to the cushion block, and is used for pulling the positioning hook to move toward the cushion block.

[0010] In a possible implementation, an end plate is fixedly mounted on one end of the positioning hook away from the cushion block, and an end portion of the tightening member is provided with an abutting portion for abutting against the end plate.

[0011] In a possible implementation, both ends of the first extrusion plate are equipped with first limiting members for hanging on the end surface of the block, and the position of the first limiting member on the first extrusion plate has the freedom to be adjusted in the direction of approaching or moving away from the block.

[0012] In a possible implementation, first pull rods are fixedly mounted on both ends of the first extrusion plate. The first pull rods pass through the first limiting member, and a first adjusting member is threadedly connected to the first pull rods for abutting against the first limiting member.

[0013] In a possible implementation, the first limiting member includes a side plate adapted to the outer diameter of the block and a limiting plate bent on the side plate, and the first pull rod is disposed through the limiting plate.

[0014] In a possible implementation, the first extrusion plate and the cushion block are both provided with guide protrusions that slide in cooperation with the positioning grooves on the outer side surfaces of the blocks.

[0015] In a possible implementation, the positioning hook includes two outer plates that are spaced apart and arranged in parallel, and both outer plates are provided with positioning protrusions for being hung on the end surface of the block.

This simple structure and the simultaneous, simultaneous winding of multiple tiles effectively improve tile winding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Please also refer to Figures 1 to 3 Now, the fixing fixture for winding a plurality of block stators provided by the present invention will be described. The fixing fixture for winding a plurality of block stators comprises a first extrusion plate 1, a second extrusion plate 2, a spacer 3, a positioning hook 4 and a tightening member 5. One side of the first extrusion plate 1 is provided with an arc-shaped surface that matches the outer diameter of the block 6; one side of the second extrusion plate 2 is provided with an arc-shaped surface that matches the inner diameter of the block 6; there is at least one spacer 3, and two opposite sides of the spacer 3 are respectively provided with arc-shaped surfaces that match the outer diameter and inner diameter of the block 6; both ends of the spacer 3 are provided with positioning hooks 4, and the positioning hooks 4 are provided with hook bodies for hanging on the ends of two adjacent blocks 6 respectively; the tightening member 5 is provided through the positioning hook 4 and is threadedly connected to the spacer 3, and is used to pull the positioning hook 4 to move in the direction close to the spacer 3.

[0025] Compared to the prior art, the fixture for winding multiple stators provided in this embodiment comprises a first extrusion plate 1 and a second extrusion plate 2, with at least one spacer 3 installed between them. The first extrusion plate 1, on the side closest to the spacer 3, has a curved surface that matches the outer diameter of the segment 6, while the second extrusion plate 2, on the side closest to the segment 6, has a curved surface that matches the outer and inner diameters of the segment 6. Furthermore, curved surfaces are provided on opposite sides of the spacer 3, respectively, matching the outer and inner diameters of the segment 6. During the winding process, multiple segments 6 can be clamped between the first extrusion plate 1 and the second extrusion plate 2. Adjacent segments 6 are connected by the spacer 3, and the relative positions of the two segments 6 are controlled by positioning hooks 4. Thus, multiple segments 6 can be squeezed between the first extrusion plate 1 and the second extrusion plate 2. Finally, the first and second extrusion plates 2 are mounted on the rotating device of the winding machine, thereby driving the simultaneous rotation of multiple segments 6 to complete the winding operation. The structure is simple, and the synchronous winding of multiple blocks 6 effectively improves the winding efficiency of the blocks 6.

[0026] Specifically, in this embodiment, when the cushion block 3 is installed between two puzzle blocks 6, it can be hung on the ends of two adjacent puzzle blocks 6 through the hook bodies on both sides of the positioning hook 4. Positioning hooks 4 are provided at both ends of the cushion block 3. The relative position of the positioning hook 4 and the cushion block 3 can be adjusted by the tightening member 5, thereby realizing the relative positioning of the two puzzle blocks 6.

[0027] Preferably, in this embodiment, a rotating shaft can be detachably installed on the outer side of the first extrusion plate 1 and the second extrusion plate 2, and the rotating shaft is used to drive the first extrusion plate 1 and the second extrusion plate 2 to rotate, and an anti-rotation protrusion is protruding from the outer surface of the first extrusion plate 1 and the second extrusion plate 2, and a slot corresponding to the anti-rotation protrusion is provided at the end of the rotating shaft.

[0028] In some embodiments, the positioning hook 4 can be used as follows Figure 1 、 Figure 2 See also Figure 1 、 Figure 2 The end of the positioning hook 4 away from the cushion block 3 is fixedly mounted with an end plate 41, and the end of the jacking member 5 is provided with an abutment portion 51 for abutting against the end plate 41. The end surface of the positioning hook 4 is fixedly mounted with the end plate 41, and the jacking member 5 is a bolt. The jacking member 5 is provided through the end plate 41 and is threadedly connected to the cushion block 3, so that the bolt head on the jacking member 5 can abut against the end plate 41. When adjusting the jacking member 5, the bolt head of the jacking member 5 is located outside the end plate 41. This makes it convenient for the operator to adjust the jacking member 5.

[0029] In some embodiments, the first extruded plate 1 may be formed as follows: Figure 3 The structure shown. Figure 3 Both ends of the first extrusion plate 1 are equipped with first stoppers 7 for mounting on the end faces of the tiles 6. The position of the first stoppers 7 on the first extrusion plate 1 can be adjusted in a direction toward or away from the tiles 6. First stoppers 7 are mounted on both ends of the first extrusion plate 1. The ends of the first stoppers 7 distal to the first extrusion plate 1 are provided with hooks for mounting on the ends of the tiles 6, thereby limiting the relative position between the first extrusion plate 1 and the tiles 6. During installation, the tiles 6 can be first mounted on the extrusion plate, and then the relative positions of the two first stoppers 7 can be adjusted so that the tiles 6 are clamped between the two first stoppers 7, thereby limiting the position of the first tile 6. After the spacer 3 is mounted on the first tile 6, the positioning hooks 4 are used to position the adjacent tiles 6. Multiple spacers 3 and tiles 6 are sequentially connected, and finally, the second extrusion plate 2 is mounted on the outermost tile 6, thereby achieving installation of the multiple tiles 6. The simple structure facilitates positioning of the multiple tiles 6.

[0030] Specifically, in this embodiment, second stoppers are installed at both ends of the second extruded plate 2. The second stoppers are used to be mounted on the end faces of the blocks 6 to position the second extruded plate 2 during installation. Furthermore, the connection structure between the second stoppers and the second extruded plate 2 is the same as the connection structure between the first stoppers 7 and the first extruded plate 1.

[0031] Specifically, in this embodiment, a limiting protrusion for hanging on the end surface of the block 6 is provided on the end of the second limiting member away from the second extrusion plate 2 and extending outward.

[0032] In some embodiments, the first limiting member 7 may be: Figure 3 The structure shown. Figure 3 A first pull rod 8 is fixedly mounted on both ends of the first extrusion plate 1. The first pull rod 8 passes through the first stopper 7 and is threadedly connected to a first adjustment member 81 for abutting against the first stopper 7. A first pull rod 8 is fixedly mounted on both ends of the first extrusion plate 1. A first adjustment member 81 is threadedly connected to the first pull rod 8. The first adjustment member 81 is a nut. The first pull rod 8 passes through the first stopper 7 and, through the first adjustment member 81, pulls the first stopper 7 toward the first extrusion plate 1, thereby causing the end of the first stopper 7 to be mounted on the end face of the block 6. This results in a simple structure and easy operation.

[0033] Specifically, in this embodiment, a limiting protrusion for hanging on the end surface of the block 6 is provided on the end of the first limiting member 7 away from the first extrusion plate 1 and extending outward.

[0034] In some embodiments, the first limiting member 7 may be: Figure 3 The structure shown. Figure 3 The first limiting member 7 includes a side plate 71 adapted to the outer diameter of the block 6 and a limiting plate 72 bent on the side plate 71. The first pull rod 8 is disposed through the limiting plate 72. The side plate 71 is an arc-shaped plate adapted to the outer diameter of the block 6. The limiting plate 72 is bent at the end of the side plate 71 near the first extrusion plate 1. The first pull rod 8 is disposed through the limiting plate 72. When the end of the first limiting plate 72 is mounted on the end face of the block 6, the first adjusting member 81 abuts against the side of the limiting plate 72, thereby limiting the block 6 between the two first limiting plates 72. The relative position of the first extrusion plate 1 and the block 6 can be adjusted by adjusting the position of the first adjusting members 81 at both ends of the first extrusion plate 1.

[0035] In some embodiments, the first extrusion plate 1 and the pad 3 can be made as follows: Figure 2 The structure shown. Figure 2, the first extrusion plate 1 and the cushion block 3 are both provided with guide protrusions 9 that slide in conjunction with the positioning grooves on the outer side of the puzzle 6. This embodiment is applicable to puzzles 6 having positioning grooves recessed on the outer side for mounting on the motor housing. The length direction of the positioning grooves is arranged along the length direction of the puzzle 6. The guide protrusions 9 slide in conjunction with the positioning grooves on the outer side of the puzzle 6, and when the puzzle 6 is connected to the first extrusion plate 1 or the cushion block 3, the guide protrusions 9 can slide into the positioning grooves, and the relative position between the puzzle 6 and the first extrusion plate 1 and the cushion block 3 is further positioned by the cooperation between the positioning grooves and the guide protrusions 9. At the same time, the stability of the puzzle 6 during the winding process is improved.

[0036] In some embodiments, the positioning hook 4 can be used as follows Figure 2 See the structure shown. Figure 2 The positioning hook 4 includes two outer plates 42 that are spaced apart and arranged in parallel. Both outer plates 42 are provided with positioning protrusions 421 for hanging on the end faces of the blocks 6. The positioning hook 4 is composed of two outer plates 42 that are spaced apart and arranged in parallel. The distance between the outer side faces of the two outer plates 42 is less than the thickness of the cushion block 3, thereby preventing two adjacent blocks 6 from being unable to effectively contact the cushion block 3. The two outer plates 42 are connected by a connecting plate, and the tightening member 5 is provided through the connecting plate. A positioning hook 4 is provided on the end of the outer plate 42 away from the cushion block 3, which protrudes outward. The positioning hook 4 is used to be limited to the end of the block 6 to limit the relative position of the block 6.

[0037] In some embodiments, the positioning hook 4 can be used as follows Figure 2 See the structure shown. Figure 2 A support plate is fixedly mounted between the two outer panels 42 to reinforce the panels 42. The two support plates are fixedly mounted between the two outer panels 42, with their lengths aligned with the lengths of the positioning hooks 4 and spaced parallel to each other. A tensioning member 5 is positioned between the two support plates. The presence of the support plates enhances the relative stability between the two outer panels 42, ensuring that the positioning hooks 4 at the ends of the outer panels 42 effectively abut against the ends of the segments 6. This ensures the stability of the segments 6 during the winding process.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
