Description

Technical Field

[0001] This utility model relates to the field of motor slide technology, specifically a miniature rod-shaped motor slide. Background Technology

[0002] With the rapid development of technology, the demand for industrial automation is growing across various industries. Automated production lines require a large number of devices capable of precise linear motion to perform tasks such as material handling, parts assembly, and machining positioning. In fields such as electronics, optics, and biomedicine, equipment miniaturization has become an important development trend.

[0003] In the field of modern precision manufacturing and automation equipment, the traditional "motor + lead screw" transmission system is the mainstream solution for achieving linear motion and is widely used in various industrial production, scientific research instruments and automation equipment. This system outputs rotational power from the motor, which is transmitted to the lead screw through the coupling, converting rotational motion into linear motion, and then driving the slide to complete the positioning and movement functions. The device includes multiple independent components such as motor, coupling, and lead screw and nut pair. The complex structure not only increases the design, manufacturing and maintenance costs of the equipment, but also introduces more mechanical losses due to the existence of multiple connection links. During the transmission process, the elastic deformation of the coupling, the friction between the lead screw and nut and the wear of the bearings will all lead to a decrease in energy transfer efficiency, resulting in increased system energy consumption and decreased operational stability.

[0004] To address these issues, we designed a miniature rod-shaped motor slide. Utility Model Content

[0005] The purpose of this invention is to provide a miniature rod-shaped motor slide to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a miniature rod-shaped motor slide, including a motor slide body and a base and a slider disposed on the motor slide body. The motor slide body is provided with a rod-shaped motor body, a mover is installed on the rod-shaped motor body, a stator is also disposed inside the rod-shaped motor body, a guide rail is provided on the motor slide body, and the base is disposed on the guide rail.

[0007] Furthermore, the number of guide rails is four.

[0014] The beneficial effects of this utility model are as follows: After the rod-shaped motor body is energized, the Ampere force will drive the magnetic rod of the rod-shaped motor body to move, thereby moving the base to displacement and realizing linear displacement output.

[0021] 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.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a miniature rod-shaped motor slide, including a motor slide body 1, a base 2 and a slider disposed on the motor slide body 1. A rod-shaped motor body 3 is disposed on the motor slide body 1, and a mover is mounted on the rod-shaped motor body 3. A stator is also disposed inside the rod-shaped motor body 3. When the rod-shaped motor body 3 is energized, according to the law of electromagnetic induction, the current passing through the mover will generate a ring magnetic field around it. The stator on the magnetic rod, by virtue of its own magnetism, constructs a stable intrinsic magnetic field. A guide rail 5 is disposed on the motor slide body 1, and the base 2 is disposed on the guide rail 5. The base 2, which is closely connected to the magnetic rod, utilizes the motor slide body... The guide rail 5 on the motor slide body 1 slides together, causing the base 2 to move along the guide rail 5. The motor slide body 1 is provided with an outer shell 8, and a cavity 7 is opened inside the outer shell 8. The rod-shaped motor body 3 is placed in the cavity 7. The motor slide body 1 is connected to a vertical plate 4, and a groove 401 is opened on the vertical plate 4. The magnetic rod of the rod-shaped motor body 3 is placed in the groove 401. The diameter of the magnetic rod of the rod-shaped motor body 3 is four millimeters. By precisely adjusting the magnitude and direction of the input current, the magnitude and direction of the Ampere force can be precisely controlled, thereby achieving precise control of the movement speed and displacement of the motor slide body 1, which greatly improves the stability and reliability of the device operation.

[0023] In practice, when the rod-shaped motor body 3 is energized, the current generates a magnetic field around it. The rod-shaped motor body 3 has a stator inside, which has its own stable magnetic field. When the magnetic field generated by the energized rotor meets the magnetic field of the stator, the two magnetic fields interact. After the rod-shaped motor body 3 is energized, the Ampere force will drive the magnetic rod of the rod-shaped motor body 3 to move. Since the rod-shaped motor body 3 is set in the cavity 7, when the magnetic rod moves under the action of the Ampere force, it will drive the base 2 to move, thereby realizing linear displacement output. By adopting efficient electromagnetic design and permanent magnet drive, the magnitude and direction of the Ampere force can be precisely controlled, making the movement response of the motor slide body 1 rapid and the control precision high. This avoids complex mechanical transmission structures, reduces mechanical losses of the device, and improves the stability of the device operation.

[0024] See Figure 2 as well as Figure 3As shown, there are four guide rails 5, and the base 2 has a circular hole 201. The symmetrical layout greatly enhances the stability and balance of the base 2 during movement. The base 2, which is closely connected to the magnetic rod, has a good sliding fit between its bottom and the guide rails 5. When the magnetic rod moves linearly under the action of Ampere force, the base 2 can slide smoothly along the symmetrically distributed guide rails 5. The guide rails 5 not only restrict the direction of movement of the base 2 and reduce swaying and offset during movement, but also effectively disperse the pressure on the base 2, further reducing mechanical losses, so that the entire motor slide body 1 can achieve high-precision linear displacement output.

[0025] In practice, the number of guide rails 5 is four, which further improves the stability of the device during operation. At the same time, the electromagnetic drive can respond quickly, and the low inertia design can achieve high-speed start and stop, making it suitable for high-frequency reciprocating motion.

[0026] See Figure 3 Bolts 6 are provided on the motor slide body 1, and guide rail 5 is set on the motor slide body 1 by bolts 6, which improves the positioning accuracy of guide rail 5, provides reliable guidance for the smooth sliding of base 2, reduces the use of complex parts, and reduces mechanical wear.

[0027] See Figure 2 The motor slide body 1 has mounting holes 101, which enhances the structural strength and spatial separation capability of the motor slide body 1. The motor slide body 1 is small in size and can be placed in narrow spaces, thus improving the practicality of the device.

[0028] It should be noted that the motor slide body 1 breaks through the traditional transmission mode and can directly achieve linear displacement output without relying on complex transmission mechanisms such as gears and lead screws. Thanks to its low inertia design, the motor slide body 1 can achieve high-speed start and stop, easily handle high-frequency reciprocating motion scenarios, and the diameter of the magnetic rod can be as small as four millimeters. It has unique advantages in space-sensitive fields such as miniaturized equipment and portable instruments, and provides more possibilities for the integrated design and space optimization of the equipment. By abandoning the complex transmission mode of the traditional motor and lead screw combination, the structure of the motor slide body 1 is greatly simplified and the operating noise is significantly reduced. By adopting a high-efficiency electromagnetic design combined with permanent magnet drive technology, the motor slide body 1 can quickly respond to control signals. After being powered on, the magnetic field generated by the mover and the magnetic field of the stator interact rapidly to generate Ampere force to drive the magnetic rod to move, realizing rapid start and precise control of the motion. The motion process of the motor slide body 1 adopts a non-contact design, avoiding direct friction and contact between mechanical parts and improving the service life of the device.

[0029] It should be noted that the motor slide body 1 is equipped with a grating and a control system. The grating is usually composed of two parts: a grating ruler and a grating reading head. When the rod-shaped motor body drives the motor slide body 1 to move, a relative displacement occurs between the grating ruler and the reading head. The displacement information fed back by the grating is transmitted to the control system of the motor slide body 1 in real time. The control system compares the actual displacement with the preset displacement. If there is a deviation, it will immediately adjust the speed, direction and other parameters of the motor slide body 1 so that the slide moves according to the predetermined trajectory and accuracy requirements, thereby improving the accuracy of the device operation.

[0030] Working principle: When the rod-shaped motor body 3 is energized, the current generates a magnetic field around it. The rod-shaped motor body 3 contains a stator, which has its own stable magnetic field. When the magnetic field generated by the energized rotor meets the stator's magnetic field, the two magnetic fields interact. After the rod-shaped motor body 3 is energized, the Ampere force drives the magnetic rod of the rod-shaped motor body 3 to move. Since the rod-shaped motor body 3 is located within the cavity 7, when the magnetic rod moves under the action of the Ampere force, it drives the base 2 to move, thereby achieving linear displacement output. Through the adoption of efficient electromagnetic design and permanent magnet drive, it can achieve precise... The precise control of the magnitude and direction of the Ampere force ensures rapid motion response and high control accuracy of the motor slide body 1, avoiding complex mechanical transmission structures, reducing mechanical losses, and improving the stability of the device operation. Furthermore, the four guide rails 5 further enhance the stability of the device operation. Simultaneously, the electromagnetic drive enables rapid response, and the low inertia design allows for high-speed start-stop, making it suitable for high-frequency reciprocating motion. The rod-shaped motor body 3 is small in size, and the overall size of the motor slide body 1 is relatively small, allowing it to be placed in narrow spaces. It offers high positioning accuracy, quiet operation, and improves the practicality of the device.
