[0026] The present invention is further described in detail below with reference to the embodiments:
[0027] like Figure 1-5 As shown, the utility model provides a combined servo motor stator core structure, including a positioning ring 1 and a plurality of stator core modules 2 clamped on the inner ring side of the positioning ring 1, the surfaces of the plurality of stator core modules 2 are respectively provided with stepped grooves 8, and the plurality of stepped grooves 8 are respectively provided with tightening mechanisms 6, and the plurality of stator core modules are each provided with a one-way locking mechanism 7 clamped with the tightening mechanism 6; the tightening mechanism 6 includes a tightening gear 64 rotatably connected to the stepped groove 8, a limiting gear 63 connected to one end of the tightening gear 64, a knob 61 connected to the limiting gear 63 and arranged on the outside of the stepped groove 8, a tightening spring plate 65 connected to the stator core module 2, and a tooth segment 66 arranged on one end side of the tightening spring plate 65, and every two adjacent stator core modules 2 are connected through the tightening gear 64 and the tightening spring plate 65; the one-way locking mechanism 7 includes a clamping block 74 clamped between the teeth of the limiting gear 63, and a reset component is provided on one side of the clamping block 74.
[0028] Furthermore, if Figure 3 、 Figure 4 As shown, one side of the multiple stator core modules 2 is respectively provided with an insertion hole 9 connected to the corresponding step groove 8, and the tightening spring plate 65 is engaged with the tightening gear 64 after passing through the insertion hole 9, and the surfaces of the multiple stator core modules 2 are respectively provided with a locking groove 10 connected to the corresponding step groove 8, the reset assembly is arranged in the locking groove 10, and the clamping block 74 is arranged at the connection between the locking groove 10 and the step groove 8.
[0029] Specifically, through the insertion hole 9, the tightening spring plate 65 can be conveniently inserted into the interior of the stepped groove 8. By providing the locking groove 10 that is the same as the stepped groove 8, the block 74 provided at the connection between the locking groove 10 and the stepped groove 8 can be conveniently used to lock the limit gear 63. The tightening spring plate 65 is an elastic plate. When the tightening gear 64 rotates in the opposite direction to loosen the tightening spring plate 65, the tightening spring plate 65 can be loosened in the stepped groove 8. After the tightening spring plate 65 is loosened, the stator core module 2 can be pulled out, which is conducive to the disassembly of the stator core module 2 after being pulled out.
[0030] like Figure 5 As shown, the reset assembly includes a tension spring 73 connected to the inner wall of the locking groove 10, a slider 72 connected to one end of the tension spring 73, and a pull plate 71 connected to the surface of the slider 72. One end of the pull plate 71 extends to the outside of the locking groove 10, and the clamping block 74 is fixedly connected to the slider 72. The outer edges of multiple stator core modules 2 are fixedly connected with T-shaped clamping blocks 4. The inner ring surface of the positioning ring 1 is provided with multiple T-shaped clamping grooves 5 along the circumferential direction. The T-shaped clamping grooves 5 are adapted to the T-shaped clamping blocks 4, and each stator core module 2 is clamped to the positioning ring 1 through the cooperation of the T-shaped clamping blocks 4 and the T-shaped clamping grooves 5. The outer edge side of each stator core module 2 is connected to two T-shaped clamping blocks 4, and each stator core module 2 is clamped to every two adjacent T-shaped clamping grooves 5 on the positioning ring 1 through two T-shaped clamping blocks 4.
[0031] Specifically, by pulling the slider 72 to squeeze the tension spring 73 through the pull plate 71, the block 74 connected to the slider 72 can be conveniently released from the lock of the limit gear 63. Through the one-to-one correspondence and interference fit of multiple T-shaped blocks 4 and multiple T-shaped slots 5, multiple stator core modules 2 can be conveniently inserted from one side into the interior of the positioning ring 1 to form a complete body, thereby improving stability.
[0032] Furthermore, if Figure 2 As shown, two winding poles 3 are fixedly connected to the inner edge of each stator core module 2 .
[0033] like Figure 4 As shown, one side of the limit gear 63 is fixedly connected to a rotating column 62, and the knob 61 is connected to one end of the rotating column 62. The rotating column 62 is driven to rotate by rotating the knob 61, thereby conveniently realizing the rotation of the limit gear 63.
[0034] The following is a detailed description of the working principle of the combined servo motor stator core structure.
[0035] like Figure 1-5As shown, after multiple stator core modules 2 are placed in a circle, the heads and tails of two adjacent stator core modules 2 are inserted into the inner side of the insertion hole 9 through the tightening spring plate 65. At this time, the tightening spring plate 65 can be fitted with the tightening gear 64 through the cooperation of the tooth segment 66 and the tooth groove opened on the outside of the tightening gear 64. During this period, the block 74 is disengaged from the teeth of the limit gear 63 by pulling the pull plate 71, thereby rotating the knob 61. When the knob 61 is rotated, it will drive the limit gear 63 and the tightening gear 64 to rotate, so that the tightening spring plate 65 is wound around the outside of the tightening gear 64, and then the knob 61 is continued to be rotated until Until the two stator core modules 2 are tightened to form a whole, and after the stator core modules 2 are merged, the pull plate 71 is loosened, so that the pull plate 71 is subjected to the force of the tension spring 73, so that the clamping block 74 limits the rotation of the limit gear 63, and then the tightening mechanism 6 on each two stator core modules 2 is operated one by one according to the above operation method, so that multiple stator core modules 2 can be tightened to form a circular body. At this time, multiple T-shaped clamping blocks 4 and multiple T-shaped slots 5 are matched one by one and interference fit, so that multiple stator core modules 2 can be conveniently inserted from one side into the interior of the positioning ring 1 to form a complete body, thereby improving stability.
[0036] When the stator core needs to be partially disassembled and replaced, the whole composed of multiple stator core modules 2 is pushed out from the positioning ring 1, and then the pull plate 71 on each stator core module 2 is pushed in turn, so that the pull plate 71 drives the block 74 away from the limit gear 63, and then the knob 61 is rotated in turn, prompting the knob 61 to drive the tightening gear 64 to rotate in the opposite direction, so that the tightening spring plate 65 on each tightening gear 64 is loosened in the stepped groove 8 respectively. Therefore, when the multiple stator core modules 2 are manually pushed outward, the tightening spring plate 65 can move outward through the insertion hole 9, so that the multiple stator core modules 2 can be separated by a distance. After separation, the damaged stator core module 2 is pushed so that the tightening spring plate 65 is completely out of the stepped groove 8, and the single damaged stator core module 2 can be disassembled for replacement.
[0037] It should be noted that when multiple stator core modules 2 are combined, the tightening spring plate 65 on each stator core module 2 must first be placed in the stepped groove 8 of the adjacent stator core module 2, so that when the multiple stator core modules 2 form a circular ring, there is a gap between every two stator core modules 2. Therefore, after the multiple tightening mechanisms 6 are rotated in sequence to tightly wrap the tightening spring plates 65, the multiple stator core modules 2 can be moved inward to form a stator core. Conversely, after the multiple tightening mechanisms 6 are rotated in sequence to loosen the tightening spring plates 65 in the stepped groove 8, the multiple stator core modules 2 can move outward to separate them.
[0038] It should be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on specific circumstances.
[0039] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
