[0020] By installing a rubber base plate, the rubber's excellent shock absorption properties can effectively absorb the vibrations generated by the base during operation. Through its own elasticity, it buffers the impact, and the contact between the rubber feet and the ground increases the friction. At the same time, it can ensure that the base will not easily shift under high frequency or high vibration conditions, thus maintaining the stable operation of the equipment and reducing the noise generated by vibration. In addition, under the influence of the rubber base plate, the bottom of the horizontal steel plate can fit more closely to the installation ground, ensuring good contact and avoiding large gaps that could lead to unstable installation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides, for example Figure 1-4 The high-speed linear motor module with ultra-high thrust shown includes a base 1 and a steel strip 8 mounted on the upper end of the base 1.
[0028] The upper outer wall of the base 1 is fixedly connected to sliders 10 near the front and rear sides respectively;
[0029] A motor assembly 5 is provided between the upper outer walls of the two sliders 10;
[0030] Each of the two sliders 10 has multiple side plates 9 evenly spaced on one side. Multiple transition steel plates 7 are fixedly connected at equal intervals to the lower outer wall of the base 1. Horizontal steel plates 6 are fixedly connected to the lower outer walls of the multiple transition steel plates 7. Multiple fastening screws 26 are provided on the upper outer walls of the multiple horizontal steel plates 6. The base 1 is fixed to the adjustable horizontal steel plates 6, and the platform is locked to the ground by the fastening screws 26, ensuring that the equipment will not shift during high-frequency vibration. The sliders 10 slide on the guide rails, ensuring smooth operation and precise positioning of the motion platform. The guide rails provide the necessary support and guiding capacity, and in parallel provide a thrust exceeding 20,000 Newtons to meet the needs of high-speed motion. The motor cooperates with the sliders 10 through the stator to achieve contactless motion, reducing friction and improving acceleration and dynamic response.
[0031] Each of the multiple fastening screws 26 has a fixing cap 23 on its upper side to restrict the position of the fastening screws 26. Each of the multiple horizontal steel plates 6 has a rubber base plate 21 fixedly connected to its lower outer wall. After the fastening screws 26 are fixed, the fixing cap 23 is screwed onto the fastening screws 26. The fixing cap 23 abuts against and restricts the position of the fastening screws 26 through its interior, preventing the fastening screws 26 from loosening and coming out under the influence of vibration.
[0032] like Figure 4 As shown, multiple threaded grooves 24 are equally spaced on the inner surface of the upper outer wall of multiple horizontal steel plates 6, and threaded rings 25 that engage with the threaded grooves 24 are fixedly connected to the lower outer wall of multiple fixed covers 23 to restrict the position of the fixed covers 23 themselves.
[0033] When the fixing cover 23 is fixed, it is fixed to the upper side of the fastening screw 26 by the engagement between the threaded ring 25 and the threaded groove 24, thereby tightening the fastening screw 26.
[0034] like Figure 4 As shown, the upper inner walls of multiple fixing covers 23 are provided with rubber layers 22, and the multiple rubber layers 22 and fixing covers 23 are fixedly connected by adhesive. Multiple rubber base plates 21 are provided with multiple openings 27 at equal intervals inside for fastening screws 26 to pass through.
[0035] The rubber layer 22 fills the inner wall of the fixing cover 23, while reducing the intrusion of external moisture and dust, and preventing the fastening screws 26 from rusting and getting stuck. The opening 27 allows the fastening screws 26 to pass through, preventing the fastening screws 26 from damaging the rubber base plate 21.
[0036] like Figure 1 , Figure 2 and Figure 3 As shown, end plates 2 are fixedly connected to the outer walls of both the left and right ends of the base 1. Impact blocks 4 are fixedly connected to the opposite sides of the two end plates 2. Buffer heads 12 are fixedly connected to one end of the opposite side of the two impact blocks 4. Impact heads 13 are provided on both the front and rear sides of the two buffer heads 12. A limiting rod 20 that penetrates the inside of the impact block 4 is fixedly connected to one end of the multiple impact heads 13. Limiting grooves 19 are opened inside the two impact blocks 4 to limit the movement distance of the limiting rod 20.
[0037] When the system is running at high speed or subjected to external impact, the impact head 13 will first come into contact with the external object or moving platform, resulting in an impact. At this time, the impact block 4 plays the role of damping the impact, absorbing some of the energy through the elasticity of its material and structural design.
[0038] like Figure 2 and Figure 3As shown, springs 18 are fixedly connected between multiple limiting rods 20 and limiting grooves 19. Pressure blocks 3 are fixedly connected to the upper outer walls of the two end plates 2, and pull blocks 17 are fixedly connected to the lower outer walls of the two pressure blocks 3 to limit the position of the steel strip 8.
[0039] The limiting rod 20 is fixedly connected to the limiting groove 19 by the spring 18. The spring 18 plays a key role in buffering and restoring. When an impact or other force is applied to the limiting rod 20, the spring 18 will be compressed to help absorb the impact force and quickly return to its original position after the force is released. The pressure block 3 and the pull block 17 are fixed to the upper outer wall of each end plate 2 to limit the vertical position of the steel strip 8.
[0040] like Figure 1 and Figure 2 As shown, a photosensitive sheet 14 is fixedly connected to the lower outer wall of the motor unit 5, multiple reading heads 15 are provided on the upper outer wall of the base 1, multiple photoelectric sensors 16 are equidistantly arranged on the front outer wall of the slider 10, magnetic scales 11 are provided on the upper outer walls of both sliders 10, and a stator is provided inside the upper outer wall of the base 1.
[0041] When the motor unit 5 is powered on, the magnetic field generated by the stator interacts with the coil inside the motor unit 5, driving the slider 10 to move on the guide rail. The photosensitive plate 14 detects the position change in real time and combines with the reading head 15 to provide position data to the control system. The photoelectric sensor 16 on the slider 10 assists in detecting the displacement of the slider 10. By emitting and receiving light beams, it determines whether the slider 10 has reached the set stroke. The magnetic scale 11 provides higher precision displacement feedback, enabling the entire system to be precisely controlled, especially under high acceleration and rapid change working conditions.
[0042] The implementation principle of this embodiment is as follows: The base 1 is fixed on an adjustable horizontal steel plate 6, and the platform is locked to the ground by fastening screws 26 to ensure that the equipment will not shift during high-frequency vibration. The slider 10 slides on the guide rail to ensure smooth operation and precise positioning of the motion platform. The guide rail provides the necessary support and guiding capacity, and provides a thrust of more than 20,000 Newtons in parallel to meet the needs of high-speed motion. The motor cooperates with the slider 10 through the stator to achieve contactless motion, reduce friction, and improve acceleration and dynamic response. After the fastening screws 26 are fixed, the fixing cover 23 is screwed onto the fastening screws 26. The inside of the fixing cover 23 abuts against and restricts the position of the fastening screws 26 to prevent the fastening screws 26 from loosening and coming off under the influence of vibration.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
