Description

Technical Field

[0001] This invention belongs to the field of motor technology, specifically relating to an electric mechanism that can be used for multi-directional adjustment. Background Technology

[0002] With the rapid development of the economy and society, automation and intelligence are becoming increasingly dominant. Motors, as the power source for actuators in various automated and intelligent equipment, are essential components of various adjustment structures. In linear adjustment mechanisms, screws and nuts are commonly used, or linear motors are employed for direct drive. However, these methods typically only allow for movement adjustment in two directions. Using the same mechanism cannot achieve multiple directions. Furthermore, the complexity of screw and nut structures increases system size, and efficiency losses in the adjustment mechanism reduce adjustment efficiency, affecting accuracy and reliability. Precision rotary tables require multi-directional adjustment to meet accuracy requirements, but existing technologies cannot achieve this through a single structure. This impacts system performance in many fields, thus hindering the development of high-precision devices. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides an electric mechanism for multi-directional adjustment. This mechanism integrates a stator composed of multiple armatures and a mover with magnets. The stator, by controlling the energizing sequence and direction of the armatures, changes the polarity of the armature core. Different polarities generate thrust in different directions relative to the magnets mounted inside the mover, propelling the mover in different directions, thus achieving multi-directional movement adjustment. This adjustment method not only enables multi-directional adjustment but also features a simple structure, small size, high adjustment efficiency, high adjustment precision, and lower cost.

[0004] The present invention is achieved through the following technical solutions.

[0005] The present invention provides an electric mechanism that can be used for multi-directional adjustment, comprising a mover and a stator; wherein the mover is connected to the moving end of the system, and the stator is fixed to the fixed end of the system by bolts;

[0006] The moving part includes a magnet, an inner sleeve, a fixed shaft, a pin, an outer sleeve, and a connecting shaft. The magnet is an axially magnetized bipolar magnet with an N pole and an S pole, the N pole or S pole facing the stator end face, and the line connecting the N pole and S pole is coaxial with the stator axis. The inner sleeve is a cylindrical sleeve with an opening at one end. The magnet is placed inside the inner sleeve. One end of the fixed shaft extends into the inner sleeve and presses against the other side of the magnet. The pin passes laterally through the fixed shaft along the outside of the inner sleeve, connecting the fixed shaft and the inner sleeve as one unit. The outer sleeve is a cylindrical sleeve with an opening at one end and a hole at the other. The inner sleeve and the fixed shaft are located inside the outer sleeve. The closed end of the inner sleeve is installed corresponding to the open end of the outer sleeve, and the open end of the outer sleeve is installed corresponding to the fixed shaft. The connecting shaft enters the outer sleeve through the open end of the outer sleeve and is axially connected to the connecting shaft as one unit.

[0007] The stator includes iron cores, a base, a connecting bracket, coils, a terminal block assembly, insulating tubes, and insulating washers. There are six iron cores, each with an upper fan-shaped structure with inner and outer arcs and a lower cylindrical shape. The upper ends of the six iron cores together form a circle. The terminal block assembly includes an insulating frame and lead wires. The insulating frame is a disc structure with six symmetrically distributed holes corresponding to the iron cores. The lower ends of the six iron cores pass through the holes in the insulating frame and are fixed to the connecting bracket. Each iron core has an insulating tube fitted onto its lower cylindrical portion, and each insulating tube has a coil fitted onto it. The start and end points of each coil are led out via lead wires. The connecting bracket is fixedly mounted on the base.

[0008] In use, the lower end of the mover is installed by mating with the upper end of the iron core, and the insulating washer is placed between the mover and the iron core and is tightly attached to the upper end of the iron core.

[0009] Furthermore, a gap is provided between the lower end of the moving element and the insulating washer.

[0010] Furthermore, the adapter shaft is provided with an external thread, and the fixed shaft is provided with a corresponding internal thread. The adapter shaft and the fixed shaft are connected as one unit by the thread.

[0011] Furthermore, the stator also includes a fixing adhesive, which is disposed on the outside of the iron core to bond the six iron cores together as a whole.

[0012] Furthermore, the six iron cores are iron core I, iron core II, iron core III, iron core IV, iron core V, and iron core VI; the terminal block assembly also includes terminal block I, terminal block II, and terminal block III;

[0013] The iron cores I, II, III, IV, V, and VI are arranged clockwise on the insulating frame. Terminal block I connects the start and end of the coils on iron cores I and IV together, terminal block II connects the start and end of the coils on iron cores II and V together, and terminal block III connects the start and end of the coils on iron cores III and VI together. After the last six iron core coils are transferred through the terminal block assembly, six leads are output. Iron cores I and IV form the first group of coils after connection, iron cores II and V form the second group of coils after connection, and iron cores III and VI form the third group of coils after connection.

[0014] Furthermore, the insulating frame is provided with 6 cylindrical bosses to isolate the lead wire from the base, preventing the lead wire from breaking and coming into contact with the base, thus damaging the motor insulation.

[0015] Furthermore, the connecting bracket includes connecting bracket I, connecting bracket II, and connecting bracket III. Connecting bracket I is connected to iron core I and iron core IV to form a first magnetic circuit; connecting bracket II is connected to iron core II and iron core V to form a second magnetic circuit; and connecting bracket III is connected to iron core III and iron core VI to form a third magnetic circuit.

[0016] Furthermore, the iron core is made of a magnetically conductive material.

[0017] Furthermore, the base is made of non-magnetic material, with a groove for mounting the connecting bracket and a through hole for threading wires on one side, and a fixing hole on the other side.

[0018] This invention involves adding insulation to the iron core and then winding enameled wire of the appropriate diameter and number of turns to form an armature. Two wires are led out from the armature. The iron core and the connecting bracket need to be made of magnetically conductive material. The connecting bracket is connected to two diagonally opposite iron cores to form a branch. Two coils on a branch are connected together at one end through a terminal block assembly to form a new coil. The new coil has a lead-out wire on each of the two armatures. When DC current is applied to the coil, a magnetic field is generated on the iron core, with one end being the N pole and the other end being the S pole. This magnetic field interacts with the polarity of the magnet inside the mover. According to the principle that like poles attract and unlike poles repel, the stator magnetic field will exert a force on the mover, thereby pushing the mover to move. Adjusting the direction of current flow in the coil will change the polarity of the parameters on the iron core, thereby pushing the mover to move bidirectionally along the line connecting the two iron cores. The principle is similar for other iron cores. Therefore, when coils composed of different iron cores are energized, they can push the mover to move bidirectionally along the line connecting the corresponding iron cores. When four adjacent iron cores, i.e. two combined coils, are energized simultaneously, the polarity generated by the four iron cores will produce a combined force on the mover, pushing the mover to move along the center line of the two iron cores. Similarly, by adjusting the direction of the coil energization, the direction of the force will be changed, and the mover can achieve bidirectional movement.

[0019] The beneficial effects of this invention are as follows: By integrating a stator composed of multiple armatures and a mover with magnets, the stator composed of multiple armatures can change the polarity generated by the armature core by controlling and adjusting the energizing sequence and direction of the armatures. Different polarities generate thrust in different directions relative to the magnets assembled inside the mover, pushing the mover to move in different directions, thereby realizing multi-directional movement adjustment. This adjustment method can not only realize multi-directional adjustment, but also does not require mechanical structures such as lead screws and nuts. It has the characteristics of small size, high adjustment accuracy, and high reliability, and is very suitable for multi-directional adjustment of high-precision mechanisms.

Detailed Implementation

[0028] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0029] The stator consists of an iron core, a base, a connecting bracket, a coil, and a terminal block assembly. The number of iron cores is even, and the number of iron cores determines the number of adjustable directions. The base is used to fix the connecting bracket, iron core, coil, and terminal block assembly. The base is provided with mounting holes and wire outlet holes. An armature is formed by adding insulation to the iron core and winding enameled wire of the appropriate diameter and number of turns. The armature has two leads. The iron core and the connecting bracket need to be made of magnetically conductive material. The connecting bracket is connected to two iron cores at opposite corners to form a branch. The two coils on a branch are connected together at one end by a terminal block assembly to form a new coil. The new coil has a lead on each of the two armatures. When DC current is applied to the coil, a magnetic field is generated on the iron core, with one end being the N pole and the other end being the S pole. This magnetic field interacts with the polarity of the magnet inside the mover. According to the principle that like poles attract and unlike poles repel, the stator magnetic field will exert a force on the mover, thereby pushing the mover to move. Adjusting the direction of current flow on the coil will change the polarity of the parameters on the iron core, thereby pushing the mover to move bidirectionally along the line connecting the two iron cores. The principle is similar for other iron cores. Therefore, when coils composed of different iron cores are energized, they can push the mover to move bidirectionally along the line connecting the corresponding iron cores. When four adjacent iron cores, i.e. two combined coils, are energized simultaneously, the polarity generated by the four iron cores will produce a combined force on the mover, pushing the mover to move along the center line of the two iron cores. Similarly, by adjusting the direction of the coil energization, the direction of the force will be changed, and the mover can achieve bidirectional movement.

[0030] like Figure 1 As shown, an electric mechanism for multi-directional adjustment consists of a mover 1 with magnets and a stator 2 integrating multiple armatures. The mover 1 comprises magnets 1.1, an inner sheath 1.2, a fixed shaft 1.3, a pin 1.4, an outer sheath 1.5, and a transition shaft 1.6. The stator 2 comprises an iron core 2.1, a base 2.2, a connecting bracket 2.3, a coil 2.4, a terminal block assembly 2.5, an insulating tube 2.6, an insulating washer 2.7, and fixing adhesive 2.8.

[0031] The mover 1 and the stator 2 are installed independently, wherein the mover 1 is connected to the moving end of the system, and the stator 2 is fixed to the fixed end of the system by bolts.

[0032] A gap with a value of δ is provided between the mover 1 and the stator 2. The size of this gap will affect the thrust. The specific size needs to be determined by comprehensive simulation based on the magnet grade and the number of coil turns.

[0033] The magnet 1.1 is an axially magnetized bipolar magnet with an N pole and a S pole; the material of the magnet 1.1 can be neodymium iron boron or rare earth cobalt permanent magnet.

[0034] The installation direction of the magnet 1.1 can be either N pole facing the stator 2 or S pole facing the stator 2. This invention will be described with the S pole facing the stator 2 as an example.

[0035] like Figure 2 As shown, the magnet 1.1 is fixed inside by the inner sleeve 1.2, the fixed shaft 1.3, and the pin 1.4, which eliminates the need for gluing or welding, resulting in higher reliability.

[0036] After the magnet 1.1 is fixed, it is threadedly connected to the fixed shaft 1.3 through the outer sheath 1.5 and the adapter shaft 1.6. The outer sheath 1.5 can prevent the pin 1.4 from falling off, further improving reliability. The adapter shaft 1.6 is connected to the moving end of the system, and the thrust generated by the mover is transmitted through the adapter shaft.

[0037] The stator 2 is a structure composed of multiple iron cores 2.1. The number of iron cores 2.1 is even. This embodiment takes a combination structure of 6 iron cores as an example to introduce the specific implementation of the present invention.

[0038] The stator 2 is composed of 6 iron cores 2.1, namely iron core I 2.1.1, iron core II 2.1.2, iron core III 2.1.3, iron core IV 2.1.4, iron core V 2.1.5, and iron core VI 2.1.6.

[0039] The iron cores I 2.1.1, II 2.1.2, III 2.1.3, IV 2.1.4, V 2.1.5, and VI 2.1.6 are arranged circumferentially.

[0040] The core 2.1 is made of a magnetically conductive material, which can be a conventional magnetically conductive material such as 2Cr13 or 45# steel, or a high-permeability soft magnetic alloy such as 1J22.

[0041] The iron core 2.1 is a combination structure of a cylinder and a sector. The cylindrical part is used to fix and wind the coil, and the sector part interacts with the mover. The size of the sector part affects the range of movement of the mover.

[0042] like Figure 3 As shown, the insulating washer 2.7 and the insulating sleeve 2.6 are placed on the iron core 2.1 to provide insulation. The coil 2.4 is made of enameled wire wound on the surface of the insulating sleeve 2.6. The coil has a start and a finish.

[0043] The enameled wire used in coil 2.4 can be either round or flat. The number of turns of coil 2.4 is determined based on comprehensive simulation according to performance requirements.

[0044] The winding direction of the coil 2.4 on the iron core I 2.1.1, iron core II 2.1.2, iron core III 2.1.3, iron core IV 2.1.4, iron core V 2.1.5, and iron core VI 2.1.6 must be consistent. It can be wound clockwise or counterclockwise. This invention will be described using clockwise winding as an example.

[0045] like Figure 4 As shown, the terminal block assembly 2.5 consists of terminal block I 2.5.1, terminal block II 2.5.2, terminal block III 2.5.3, insulating frame 2.5.4, and lead wire 2.5.5. Terminal block I 2.5.1, terminal block II 2.5.2, terminal block III 2.5.3, and insulating frame 2.5.4 can be integrally formed by injection molding. Terminal block I 2.5.1 connects the start and end of the coils on core I 2.1.1 and core IV 2.1.4 together, and terminal block II 2.5.2 connects core II... 2.1.2 The start and end of the coil on core V 2.1.5 are connected together. The terminal block Ⅲ 2.5.3 connects the start and end of the coil on core Ⅲ 2.1.3 and core VI 2.1.6 together. After the original coils of the last six cores are transferred through the terminal block assembly 2.5, six leads are output. Core I 2.1.1 and core IV 2.1.4 form a new group of coils, core II 2.1.2 and core V 2.1.5 form a second group of coils, and core III 2.1.3 and core VI 2.1.6 form a third group of coils.

[0046] Terminal blocks I 2.5.1, II 2.5.2, and III 2.5.3 are made of copper and are used to connect two coils.

[0047] The insulating frame 2.5.4 has six holes through which the iron core 2.1 passes and connects to the connecting bracket 2.3. The insulating frame 2.5.4 also has six cylindrical bosses to isolate the lead wire 2.5.5 from the base 2.2, preventing damage to the lead wire from contacting the base and damaging the motor insulation. Each cylindrical boss has a through hole through which the mounting wire passes.

[0048] There are a total of 6 lead wires 2.5.5. Two lead wires are drawn from each group of coils and connected to the three groups of coils after combination to energize the coils. The two lead wires of the combined coil of iron core I 2.1.1 and iron core IV 2.1.4 are defined as A1 and A2. The two lead wires of the combined coil of iron core II 2.1.2 and iron core V 2.1.5 are defined as B1 and B2. The two lead wires of the combined coil of iron core III 2.1.3 and iron core VI 2.1.6 are defined as C1 and C2.

[0049] The connecting bracket 2.3 is composed of connecting bracket I 2.3.1, connecting bracket II 2.3.2, and connecting bracket III 2.3.3. Connecting bracket I 2.3.1 is connected to iron core I 2.1.1 and iron core IV 2.1.4 to form a first magnetic circuit; connecting bracket II 2.3.2 is connected to iron core II 2.1.2 and iron core V 2.1.5 to form a second magnetic circuit; and connecting bracket III 2.3.3 is connected to iron core III 2.1.3 and iron core VI 2.1.6 to form a third magnetic circuit.

[0050] The connecting brackets I 2.3.1, II 2.3.2, and III 2.3.3 are made of magnetically conductive material, which may or may not be the same as the material of the iron core 2.1.

[0051] The base 2.2 is used to fix the connecting bracket I 2.3.1, connecting bracket II 2.3.2, and connecting bracket III 2.3.3, and also for wire output and fixing the entire stator.

[0052] The base 2.2 is made of non-magnetic material. One side of the base has a groove for mounting the connecting bracket and a through hole for threading wires, and the other side has a fixing hole.

[0053] like Figure 5-7 As shown, when the combined coil of core I 2.1.1 and core IV 2.1.4 is powered on, with A1 connected to the positive terminal and A2 connected to the negative terminal, the N pole generated on the fan-shaped bottom surface of core I 2.1.1 and the S pole generated on the fan-shaped bottom surface of core IV 2.1.4 interact with the magnetic field generated by the magnet 1.1 of the mover 1, generating a thrust F7 along the line connecting the center lines of core I 2.1.1 and core IV 2.1.4. When the power is reversed, with A1 connected to the negative terminal and A2 connected to the positive terminal, the S pole generated on the fan-shaped bottom surface of core I 2.1.1 and the N pole generated on the fan-shaped bottom surface of core IV 2.1.4 will generate a thrust F1 along the line connecting the center lines of core I 2.1.1 and core IV 2.1.4.

When the power is reversed, with A1 connected to the negative terminal and A2 connected to the positive terminal, the S pole generated on the fan-shaped bottom surface of core II 2.1.2 and the N pole generated on the fan-shaped bottom surface of core V 2.1.5 will generate a thrust F11 along the line connecting the centerlines of core II 2.1.2 and core V 2.1.5.

When the power is reversed, with A1 connected to the negative terminal and A2 connected to the positive terminal, the S pole generated on the fan-shaped bottom surface of core III2.1.3 and the N pole generated on the fan-shaped bottom surface of core VI2.1.6 will generate a thrust F9 along the line connecting the centerlines of cores III2.1.3 and VI2.1.6.

[0056] When the combined coils of core I 2.1.1 and core IV 2.1.4, and core II 2.1.2 and core V 2.1.5 are simultaneously powered on, with A1 and B1 connected to the positive terminals and A2 and B2 connected to the negative terminals, the N pole generated on the fan-shaped bottom surface of core I 2.1.1 and core II 2.1.2, and the S pole generated on the fan-shaped bottom surface of core IV 2.1.4 and core V 2.1.5, form a magnetic field that is similar to the magnetic field generated by the magnet 1.1 of the mover 1.

When the current is reversed, with A1 and B1 connected to the negative terminal and A2 and B2 connected to the positive terminal, the S pole generated on the fan-shaped bottom surface of core I 2.1.1 and core II 2.1.2, and the N pole generated on the fan-shaped bottom surface of core IV 2.1.4 and core V 2.1.5 will generate a thrust F12 along the centerline of core I 2.1.1 and core IV 2.1.4.
