[0003] Traditional technology relies on mounting the stator support on the bed shoulder, which has problems such as high dependence on the machining accuracy of the bed, poor flexibility in support adjustment, and the influence of magnetic attraction.

[0004] A search revealed a Chinese patent with authorization announcement number CN221328797U, which discloses a linear motor for high-precision machine tools, including a stator mounting base, two mover mounting bases located on both sides of the stator mounting base, and a connecting base connecting the two mover mounting bases; the connecting base and the two mover mounting bases form a receiving cavity.

[0005] The linear motor for high-precision machine tools mentioned in the above patent has the following shortcomings: Although the device solves the problem that the normal magnetic attraction force of the linear motor affects the accuracy and motion control performance of the high-precision machine tool;

[0006] However, the stator support on this device is positioned using the reference surface of the bed guide rail, which also presents the same problem. Consequently, it cannot effectively address the cumulative installation error caused by ultra-long stroke machine tools. Therefore, an ultra-large linear motor adjustable stator support structure is needed to solve this problem. Utility Model Content

[0009] By adopting the above technical solution, through the modular integration of the inverted T-shaped back plate and the dynamic adjustment with special adjusting bolts and fixing bolts, high-precision stator installation, gap adaptive compensation and magnetic attraction force cancellation can be achieved. The width of the bottom lateral extension flange facilitates the installation and fixation of the external bracket, while suppressing bending deformation caused by magnetic attraction force.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application utilizes a T-shaped backplate and other components, with modular integration of the inverted T-shaped backplate and dynamic adjustment via specially designed adjusting bolts and fixing bolts. This enables high-precision stator installation, adaptive gap compensation, and magnetic force cancellation.

[0035] Reference Figure 1-3 An adjustable stator support structure for an ultra-large linear motor includes a bed 1, a T-shaped back plate 2 for mounting to an external support on the bed 1, corresponding stators 3 on both sides of the T-shaped back plate 2, and corresponding movers 4 on the side of the two stators 3 that are far apart from each other. The T-shaped back plate 2 is screwed with corresponding adjusting bolts 5 and fixing bolts 6 respectively. The T-shaped back plate 2 is a split inverted T-shaped arrangement.

[0036] In use, the stator 3 can be installed with high precision, adaptive gap compensation, and magnetic force cancellation through modular integration of the inverted T-shaped back plate 2 and dynamic adjustment with special adjusting bolts 5 and fixing bolts 6. The width of the bottom lateral extension flange facilitates the installation and fixation of the external bracket, while suppressing bending deformation caused by magnetic force. Furthermore, multiple stator 3 sections can be installed symmetrically on both sides, and multiple stator 3 back plates can be infinitely extended along the longitudinal direction of the bed 1 through modular splicing mode. The tooling can be quickly positioned by pre-reserved holes in the bed 1. For deviation parts, the precision can be directly adjusted by special bolts, improving installation efficiency, resisting magnetic force deformation, and modular infinite expansion capability. Compared with the existing technology, the stator bracket of this application can reduce the processing cost and maintenance cost of the bed 1, and improve tolerance compatibility and environmental adaptability.

[0037] The special bolt described in this application is a prior art product in this field, therefore its specific structure and installation method are not described in detail.

[0038] Example 2

[0039] Reference Figure 3-4An adjustable stator support structure for an ultra-large linear motor includes T-slots 10 symmetrically opened on both sides of a T-shaped back plate 2. A corresponding T-block 11 is slidably installed in each of the two T-slots 10. The two T-blocks 11 are fixedly installed with the corresponding stator 3. Two positioning slots 8 are symmetrically opened on one side of the T-shaped back plate 2. A corresponding positioning block 9 is slidably installed in each of the two positioning slots 8. The same positioning plate 7 is fixedly installed on one side of each of the two positioning blocks 9. The positioning plate 7 is located on one side of the T-block 11 and covers it.

[0040] Among them, two mounting seats 12 are symmetrically fixedly installed on the positioning plate 7, and corresponding mounting bolts 13 are screwed onto each of the two mounting seats 12. Two assembly slots 14 for assembly are symmetrically opened on one side of the stator 3. Corresponding assembly blocks 15 are slidably installed in each of the two assembly slots 14, and the two assembly blocks 15 are fixedly installed with the adjacent stator 3.

[0041] In use, the T-shaped back plate 2 is provided with T-shaped grooves 10 and T-shaped blocks 11 to facilitate the support, positioning and installation of the stator 3. The positioning grooves 8 and positioning blocks 9 facilitate the positioning and installation of the positioning plate 7. Furthermore, the positioning plate 7 can block and limit the T-shaped grooves 10 and T-shaped blocks 11, thus completing the positioning and installation of the stator 3.

[0042] Reference Figure 5-6 The stator 3 and the two assembly blocks 15 are all provided with the same insertion hole 20. The top of the stator 3 is provided with a mounting hole 16, which is larger than the insertion hole 20. A mounting post 17 is provided in the insertion hole 20. A thread 19 is provided on the mounting post 17. A nut 18 is screwed onto the thread 19. The nut 18 is located in the mounting hole 16. The width of the nut 18 is smaller than the width of the mounting hole 16. By making the width of the nut 18 smaller than the width of the mounting hole 16, it is easier to disassemble and assemble the nut 18 with external tools, thereby improving the convenience and flexibility of use.

[0043] In use, the assembly slot 14 and assembly block 15 facilitate the assembly and splicing of adjacent stators 3. By installing the mounting post 17 in the mounting hole 16 and rotating the nut 18, the mounting post 17 can be positioned and installed, thus facilitating the assembly and fixing of adjacent stators 3.

[0044] The implementation principle of the adjustable stator support structure for an ultra-large linear motor in this application embodiment is as follows: When in use, the inverted T-shaped back plate 2 is modularly integrated and dynamically adjusted with the special adjusting bolts 5 and fixing bolts 6, thereby achieving high-precision installation of the stator 3, adaptive gap compensation and magnetic attraction cancellation. The width of the bottom lateral extension flange facilitates the installation and fixation of the external support, while suppressing the bending deformation caused by magnetic attraction.

[0045] Furthermore, by installing multiple stator 3 sections symmetrically on both sides, and by allowing multiple stator 3 backplates to be infinitely extended along the longitudinal direction of the bed 1 through modular splicing, and by reserving holes in the bed 1 for convenient and quick positioning of tooling, the deviation parts can be directly adjusted for precision by special bolts, thus improving installation efficiency, resisting magnetic attraction deformation and modular infinite expansion capability. Compared with the existing technology, the stator bracket of this application can reduce the processing cost and maintenance cost of the bed 1, and improve tolerance compatibility and environmental adaptability.

[0046] The T-shaped back plate 2 has T-shaped grooves 10 and T-shaped blocks 11, which facilitates the support, positioning and installation of the stator 3. The positioning grooves 8 and positioning blocks 9 facilitate the positioning and installation of the positioning plate 7. The positioning plate 7 can block and limit the T-shaped grooves 10 and T-shaped blocks 11, thus completing the positioning and installation of the stator 3. The assembly grooves 14 and assembly blocks 15 facilitate the assembly and splicing of adjacent stators 3. By installing the mounting post 17 in the mounting hole 16 and rotating the nut 18, the mounting post 17 can be positioned and installed, thus facilitating the assembly and fixing of adjacent stators 3.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
