Description

Technical Field

[0001] This utility model belongs to the field of linear motor technology, specifically relating to a multi-segment stator splicing linear motor. Background Technology

[0002] A linear motor is a type of mechanical energy that directly converts electrical energy into linear motion by expanding a closed magnetic field into an open magnetic field, without the need for any other transmission devices. Specifically, a linear motor servo system is a power device that converts electrical energy into linear motion mechanical energy. It eliminates the intermediate conversion link of a rotary motor and effectively overcomes many shortcomings of traditional conversion mechanisms, such as large size, low precision, low efficiency, slow response, and high noise.

[0003] Existing linear motors are prone to defects such as poor stator straightness and complicated assembly positioning during assembly. This not only greatly reduces production efficiency, but also causes uneven force distribution during operation. In addition, the stator of most linear motors is made by gluing multiple magnets to the surface of a magnetic plate to form a magnetic field circuit. It is common for the magnets on the same magnetic plate to break, rendering the entire stator unusable, which affects the production efficiency of the motor. Utility Model Content

[0004] The purpose of this invention is to provide a multi-segment stator splicing linear motor that facilitates stator module replacement in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A multi-segment stator splicing linear motor includes a base and slide rails disposed on both sides of the upper surface of the base, wherein a mover is slidably disposed on the slide rails, and further includes:

[0007] Stator splicing plates, of which there are multiple stator splicing plates and which are movably mounted on the base, and the stator splicing plates are interconnected with each other;

[0008] Stator module, wherein the stator module is movably mounted on the stator splicing plate;

[0009] Bolts, wherein multiple bolts are movably mounted on the base, and the stator splicing plate is connected to the base by bolts;

[0010] An embedded plate, wherein multiple embedded plates are slidably mounted on the stator splicing plate, and the position of the stator module is fixed by the embedded plates;

[0011] The extrusion blocks are multiple and slidably disposed on the stator splicing plate. The extrusion blocks are pressed by bolts, thereby changing the position of the embedded plate.

[0012] As a further optimization of this utility model, a trapezoidal block is provided at one end of the stator splicing plate, and a trapezoidal groove is provided at the other end of the stator splicing plate, and the stator splicing plate matches the trapezoidal groove.

[0013] As a further optimization of this utility model, the multiple embedded plates are connected by a connecting plate, the connecting plate is provided with an inclined block, the connecting plate is disposed inside the stator splicing plate, and a spring is provided between the connecting plate and the stator splicing plate.

[0014] As a further optimization of this utility model, the extrusion block is provided with an inclined surface, which matches the inclined block.

[0015] As a further optimization of this utility model, the extrusion block is sleeved on the bolt.

[0016] As a further optimization of this utility model, the stator module has grooves on both sides, and the embedding plate can be embedded in the grooves.

[0017] As a further optimization of this utility model, the base is provided with end plates at both ends, and anti-collision posts are provided on the end plates.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. Unlike existing technologies, in actual use, multiple stator splicing plates are connected to each other by a trapezoidal block at one end and a trapezoidal slot at the other end. This splicing method makes the connection between the stator splicing plates tight and stable, effectively improving the straightness of the stator and solving the problem of poor stator straightness in existing linear motors. This ensures that the motor exerts force evenly during operation and improves the running stability of the motor.

[0020] 2. Unlike existing technologies, in actual use, the stator splicing plate is connected and fixed to the base by multiple bolts. When the bolts are installed, the bolts press against the pressing blocks fitted on them. The inclined surfaces on the pressing blocks push the inclined blocks on the connecting plate, causing the connecting plate to move and change the position of the embedded plate. This allows the stator module to be fixed, thus enabling the replacement and maintenance of individual stator modules. This avoids the situation where the entire stator becomes unusable due to the breakage of the magnets on the same magnetic plate, reducing the maintenance cost of the motor and improving the production efficiency of the motor.

[0027] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Example 1

[0029] like Figure 1 - Figure 5 As shown, a multi-segment stator splicing linear motor includes a base 1 and slide rails 9 set on both sides of the upper surface of the base 1. A mover 3 is slidably set on the slide rails 9. The slide rails 9 provide a precise motion track for the mover 3, ensuring that the mover 3 slides smoothly and linearly, and ensuring the straightness and accuracy of the motor operation. End plates 2 are set at both ends of the base 1, and anti-collision posts 21 are set on the end plates 2.

[0030] It also includes:

[0031] Stator splicing plate 4, there are multiple stator splicing plates 4 and they are movably mounted on the base 1, and the stator splicing plates 4 are connected to each other;

[0032] Stator module 5 is movably mounted on stator splicing plate 4;

[0033] Bolts 8, multiple bolts 8 are movably mounted on the base 1, and the stator splicing plate 4 is connected to the base 1 by bolts 8;

[0034] Embedded plate 6, multiple embedded plates 6 are slidably set on stator splicing plate 4, and the position of stator module 5 is fixed by embedded plate 6;

[0035] The extrusion block 7, which consists of multiple blocks and is slidably mounted on the stator splicing plate 4, is pressed by the bolt 8, thereby changing the position of the extrusion block 7 on the embedded plate 6.

[0036] One end of the stator splicing plate 4 is provided with a trapezoidal block 41, and the other end of the stator splicing plate 4 is provided with a trapezoidal groove 42. The stator splicing plate 4 and the trapezoidal groove 42 are matched and can be flexibly spliced ​​and combined. The stator length and shape can be adjusted according to different needs, thereby enhancing the versatility and adaptability of the motor.

[0037] Multiple embedded plates 6 are connected by connecting plates 61. The connecting plates 61 are provided with inclined blocks 62. The connecting plates 61 are set inside the stator splicing plate 4. A spring 63 is provided between the connecting plates 61 and the stator splicing plate 4. The embedded plates 6 facilitate the overall adjustment of the fixing effect on the stator module 5.

[0038] The pressing block 7 has an inclined surface that matches the inclined block 62. When the bolt 8 is pressed, it can push the inclined block 62 through the inclined surface, thereby driving the connecting plate 61 and the embedded plate 6 to move.

[0039] The pressing block 7 is fitted onto the bolt 8. Rotating the bolt 8 presses the pressing block 7, thereby adjusting the position of the embedded plate 6 and thus adjusting the fixed state of the stator module 5.

[0040] The stator module 5 has grooves 51 on both sides, and the embedded plate 6 can be embedded in the grooves 51 to facilitate installation, adjustment and replacement, and improve maintenance efficiency.

[0041] It should be noted that the working principle of this multi-segment stator splicing linear motor is as follows: The motor mainly consists of a base 1, slide rails 9, a mover 3, stator splicing plates 4, stator modules 5, bolts 8, embedded plates 6, and pressing blocks 7. The base 1 serves as the basic support structure, with end plates 2 at both ends. The anti-collision posts 21 on the end plates 2 can prevent collisions when the mover 3 moves to the ends. Slide rails 9 are provided on both sides of the upper surface of the base 1, allowing the mover 3 to slide on the slide rails 9. Multiple stator splicing plates 4 are movably mounted on the base 1. They are connected to each other through trapezoidal blocks 41 at one end and trapezoidal grooves 42 at the other end, thus achieving splicing and assembly. The stator splicing plates 4 are connected and fixed to the base 1 by multiple bolts 8, facilitating installation and disassembly. The stator modules 5 are movably mounted on the stator splicing plates 4, and grooves 5 are provided on both sides of the stator modules 5. 1. The embedded plate 6 can be embedded in the groove 51 to fix the position of the stator module 5. Multiple embedded plates 6 are connected by a connecting plate 61. The connecting plate 61 is set in the stator splicing plate 4, and a spring 63 is set between the connecting plate 61 and the stator splicing plate 4. The pressing block 7 is sleeved on the bolt 8, and the pressing block 7 has an inclined surface that matches the inclined block 62 on the connecting plate 61. When the bolt 8 is rotated, the bolt 8 will press the pressing block 7. After the pressing block 7 is subjected to force, its inclined surface will push the inclined block 62, thereby driving the connecting plate 61 to move and change the position of the embedded plate 6, thereby realizing the adjustment of the fixed state of the stator module 5. At the same time, it can realize the replacement and maintenance of a single stator module 5. During the entire operation of the motor, the stator module 5 generates a magnetic field, and the mover 3 moves linearly along the slide rail 9 under the action of the magnetic field to achieve the working purpose of the motor.

[0042] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
