Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a magnet attaching fixture, particularly a magnet attaching fixture for a linear motor. Background Technology

[0002] A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without requiring any intermediate conversion mechanism.

[0003] Existing linear motors generally include a mover section and a stator section. The stator section includes a base plate and a row of magnets glued to the top of the base plate. The magnets are usually manually glued on using specific tooling. One such tooling structure is a single-row stator mounting fixture for linear motors disclosed in the Chinese Patent Database (application number: 202322637280.4). This fixture includes a base plate and a magnet-attaching clamp threaded to one side of the base plate. The clamp includes a vertical plate threaded to the base plate and a flat plate integrally formed with the upper surface of the vertical plate. The flat plate includes a long strip connected to the vertical plate and several oblique strips arranged on the long strip. The oblique strips extend to the other side of the base plate, forming several placement slots for placing stator magnets. The length of the oblique strips is less than the length of the magnets.

[0004] In the above mounting fixture, the length of the magnetic clamp needs to be similar to or the same as that of the base plate. When facing a longer base plate, the magnetic clamp also needs to be set to be longer, which not only takes up a lot of space, but can only be adapted to base plates of a certain length range, resulting in poor practicality. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a short linear motor magnet attaching fixture.

[0006] The objective of this utility model can be achieved through the following technical solution: A linear motor magnet attaching fixture, the linear motor including a base plate and a row of magnet assemblies arranged front and back on the base plate along the length direction of the base plate, the magnet assembly consisting of two magnetic blocks distributed along the width direction of the base plate, the magnet attaching fixture including a mounting plate horizontally arranged on the base plate, the mounting plate having multiple vertically penetrating guide grooves that match the magnet assemblies, and the multiple guide grooves being distributed along the length direction of the base plate, characterized in that the mounting plate consists of a base plate and a movable plate detachably fixed to the front end of the base plate, and both the base plate and the movable plate are horizontally arranged; a guide groove is formed between the front end of the movable plate and the base plate; the bottom of the base plate has a positioning groove that penetrates along the length direction of the base plate and matches the base plate, the multiple guide grooves on the base plate are aligned with and connected to the positioning groove, and the base plate is sleeved on the base plate through the positioning groove; the bottom of the movable plate is correspondingly provided with a limiting groove that matches the base plate, the front end and rear end of the limiting groove being closed and open respectively, the movable plate can be sleeved on the base plate through the limiting groove and the front end surface of the base plate abuts against the front end surface of the limiting groove.

[0007] In use, first place the entire mounting plate on the base plate so that the front end of the base plate presses against the front end of the limiting groove to limit the initial position of the mounting plate. Then, attach the magnets to the base plate through the guide groove. Next, separate the base plate and the movable plate, lift the base plate up and move it backward so that the front end of the base plate fits into the tail of the row of magnets that have already been attached, and then install the subsequent magnets.

[0008] The mounting plate uses a separable movable plate and a base plate. The movable plate and base plate work together to define the initial position of the magnet installation, and the subsequent magnet installation is carried out directly by moving the base plate. This can effectively shorten the length of the entire mounting plate, which not only occupies little space, but also allows the entire fixture to be adapted to base plates of different lengths by moving the base plate, making it extremely versatile.

[0009] In the above-mentioned linear motor magnet attaching fixture, both the left and right ends of the movable plate are detachably fixed to the base plate through a connector, and the aforementioned limiting groove is located between the two connectors.

[0010] In the aforementioned linear motor magnet-attaching fixture, the rear end of the movable plate presses against the front end of the base plate. The connecting component is a bolt, which is horizontally positioned. The base plate has two threaded holes for the bolt shanks to screw into, and the bolt heads press against the movable plate. The base plate and the movable plate are detachably connected by bolts, which not only facilitates assembly and disassembly but also ensures good connection stability, guaranteeing a smooth and precise magnet-attaching process.

[0011] In the aforementioned linear motor magnet mounting fixture, the threaded hole is located on the front end face of the substrate, and two through holes are correspondingly provided on the bottom wall of the movable plate. The bolt shank passes through the corresponding through hole and is screwed into the corresponding threaded hole. This design reduces the outward protrusion of the mounting plate, further reducing space occupation.

[0012] In the above-mentioned linear motor magnet attachment fixture, the bottom of the through hole is open to reduce the stress on the moving plate during through hole processing and ensure the strength of the moving plate.

[0013] As another option, in the above-mentioned linear motor magnet attachment fixture, the connecting part is a limiting rod horizontally formed on the rear end face of the movable plate, and the length of the limiting rod extends front and back. The substrate has two corresponding insertion holes that match the limiting rod, and the two limiting rods are respectively engaged in the two insertion holes.

[0014] In the aforementioned linear motor magnet mounting fixture, the front end of the base plate has a vertically penetrating strip-shaped notch one, and the rear end of the movable plate has a vertically penetrating strip-shaped notch two. The lengths of both strip-shaped notches one and two extend along the width direction of the base plate, and the guide groove is formed between strip-shaped notches one and two. This design facilitates design and manufacturing.

[0015] In the linear motor magnet mounting fixture described above, the width of the second strip notch is greater than the width of the first strip notch. By reducing the width of the first strip notch, the contact area between the substrate and the magnet is reduced, making it easier for the strip notch to fit onto the magnet in front, thus facilitating the use of the fixture.

[0016] Compared with existing technologies, this linear motor magnet attaching fixture has the following advantages: 1. The mounting plate uses a separable movable plate and a base plate. The movable plate and base plate work together to define the initial position of the magnet installation. Subsequent magnet installation is carried out directly by moving the base plate. This can effectively shorten the length of the entire mounting plate, which not only occupies little space, but also allows the entire fixture to be adapted to base plates of different lengths by moving the base plate, making it extremely versatile.

[0017] 2. By reducing the width of the first strip notch, the contact area between the substrate and the magnetic block is reduced, making it easier for the strip notch to fit into the front magnetic block and facilitating tooling use. Attached Figure Description

Detailed Implementation

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] Example 1: As Figure 3 As shown, in this linear motor magnet mounting fixture, the linear motor includes a base plate 1 and a row of magnet assemblies 2 arranged back-to-back on the base plate 1 along its length. Each magnet assembly 2 consists of two magnetic blocks 2a distributed along the width of the base plate 1. In the actual product, the magnetic blocks 2a are inclined, and the positions of the two magnetic blocks 2a in the same magnet assembly 2 are slightly offset to reduce cogging force and thrust fluctuation, thereby improving the smoothness and efficiency of motor operation.

[0025] like Figure 1 and Figure 2 As shown, this linear motor magnet mounting fixture includes a mounting plate 3 horizontally mounted on a base plate 1. The length of the mounting plate 3 extends along the length direction of the base plate 1, and the length of the mounting plate 3 is less than the length of the base plate 1. The mounting plate 3 has multiple vertically penetrating guide grooves 3a. The shape and size of the guide grooves 3a are matched with the magnet assembly 2. At this time, the length of the guide grooves 3a extends along the width direction of the base plate 1, and the multiple guide grooves 3a are spaced apart along the length direction of the base plate 1.

[0026] Specifically The mounting plate 3 consists of a base plate 3b and a movable plate 3c detachably fixed to the front end of the base plate 3b. Both the base plate 3b and the movable plate 3c are horizontally arranged and side-by-side. A guide groove 3a is formed between the movable plate 3c and the front end of the base plate 3b, as described above. The base plate 3b has multiple guide grooves. Figures 1 to 4 As shown, the bottom of the substrate 3b has a positioning groove 3b1 that extends through the base plate 1 along its length. The shape and size of the positioning groove 3b1 match the base plate 1, and the substrate 3b is fitted onto the base plate 1 through the positioning groove 3b1. Multiple guide grooves 3a on the substrate 3b are aligned with and connected to the positioning groove 3b1. The bottom of the movable plate 3c has a corresponding limiting groove 3c1 whose shape and size match the base plate 1. The front and rear ends of the limiting groove 3c1 are closed and open, respectively. The movable plate 3c can be fitted onto the base plate 1 through the limiting groove 3c1, and the front end of the base plate 1 presses against the front end of the limiting groove 3c1.

[0027] like Figure 3 and Figure 4 As shown, in use, first, the entire mounting plate 3 is placed on the base plate 1 so that the front end of the base plate 1 presses against the front end of the limiting groove 3c1 to limit the initial position of the mounting plate 3. Then, the magnet is attached to the base plate 1 through the guide groove 3a. Next, the base plate 3b and the movable plate 3c are separated, the base plate 3b is lifted and moved backward so that the front end of the base plate 3b is inserted into the tail of the row of magnets 2a that have been attached. Then, the subsequent magnets 2a are installed.

[0028] The mounting plate 3 uses a separable movable plate 3c and a base plate 3b. The movable plate 3c and the base plate 3b work together to define the initial position of the magnet installation. The subsequent installation of the magnet block 2a can be carried out directly by moving the base plate 3b. This can effectively shorten the length of the entire mounting plate 3, which not only occupies less space, but also allows the entire fixture to be adapted to base plates 1 of different lengths by moving the base plate 3b, making it extremely versatile.

[0029] In this embodiment, like Figure 2 As shown, both ends of the movable plate 3c are detachably fixed to the base plate 3b via a connector, and the aforementioned limiting groove 3c1 is located between the two connectors. Specifically, the rear end of the movable plate 3c presses against the front end of the base plate 3b; the connector is a bolt 4, which is horizontally positioned. The base plate 3b has two threaded holes for the shanks of the two bolts 4 to be screwed into, and the heads of the bolts 4 press against the movable plate 3c. The base plate 3b and the movable plate 3c are detachably fixed by the bolts 4, which not only facilitates disassembly and assembly but also ensures good connection stability, guaranteeing a smooth and accurate process for attaching the magnetic block 2a. Further, the threaded holes are located on the front end face of the base plate 3b, and two corresponding through holes 3c2 are provided on the bottom wall of the movable plate 3c. The shanks of the bolts 4 pass through the corresponding through holes 3c2 and are screwed into the corresponding threaded holes. This design reduces the outward protrusion of the mounting plate 3, further reducing space occupation. Preferably, the through holes 3c2 are open on the lower side to reduce the stress on the movable plate 3c during the machining of the through holes 3c2, ensuring the strength of the movable plate 3c.

[0030] The guide groove 3a is formed as follows: the front end of the substrate 3b has a vertically penetrating strip-shaped notch 3b2, and the rear end of the movable plate 3c has a vertically penetrating strip-shaped notch 3c3. The lengths of both strip-shaped notches 3b2 and 3c3 extend along the width direction of the base plate 1, and the guide groove 3a is formed between the strip-shaped notches 3b2 and 3c3. This design facilitates design and manufacturing. Preferably, the width of the strip-shaped notch 3c3 is greater than the width of the strip-shaped notch 3b2. By reducing the width of the strip-shaped notch 3b2, the contact area between the substrate 3b and the magnetic block 2a is reduced, making it easier for the strip-shaped notch 3b2 to fit into the front magnetic block 2a and facilitating tooling use.

[0031] Example 2: The structure and principle of Example 2 are basically the same as those of Example 1. The difference is that the connecting part is a limiting rod formed horizontally on the rear end face of the movable plate 3c, and the length of the limiting rod extends front and back. The substrate 3b has two corresponding insertion holes that match the limiting rod, and the two limiting rods are respectively engaged in the two insertion holes.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
