Technical Field

[0001] This utility model relates to the field of permanent magnet speed controllers, specifically to an installation device for assembling permanent magnets. Background Technology

[0002] Since the permanent magnets used in high-power permanent magnet speed controllers are strong magnets, it is difficult to guarantee that the permanent magnets will not be damaged after installation without tooling.

[0003] Meanwhile, during the installation of the permanent magnet, there is a large instantaneous impact force with the steel permanent magnet pressure plate. It is necessary to adjust the distance between the permanent magnet pressure plate and the disk with bolts to control the magnitude of the impact force and reduce impact damage. More importantly, if tooling is not used, the permanent magnet may attract the permanent magnet that has already been installed next to it during installation, which will lead to damage to the permanent magnet or even personal injury accidents.

[0004] The existing patent 201420763469.6 - Permanent magnet rotor for permanent magnet speed controller and permanent magnet speed controller only discloses the structure of the permanent magnet rotor and the structure of the permanent magnet speed controller, but it does not disclose how to install the permanent magnet on the permanent magnet disk.

[0029] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0030] An installation device for assembling permanent magnets includes a positioning structure; the positioning structure includes a magnet base 4 and a positioning mechanism; the magnet base 4 is provided with an assembly hole 5; the positioning mechanism includes a central positioning block 1 inserted into a permanent magnet disk 10; the magnet base 4 is rotatably connected to the central positioning block 1, and the magnet base 4 can rotate relative to the central positioning block 1; this utility model discloses an installation device for assembling permanent magnets; this utility model, through the cooperative use of the magnet base 4 and the positioning mechanism, can assist in the installation and assembly of permanent magnets on a permanent magnet disk 10.

[0031] In addition, the mounting hole 5 on the magnet base 4 of this utility model can be used to limit the permanent magnet when it is placed on the permanent magnet disk 10, so as to better ensure the accuracy of the placement of the permanent magnet on the permanent magnet disk 10.

[0032] In this invention, the positioning structure is mainly used for the installation and positioning of permanent magnets.

[0033] In this utility model, the corresponding central positioning block 1 is installed in the hole in the middle of the permanent disk 10, and the connecting positioning block 3 is then connected to the positioning pin 2 on the central positioning block 1. In this utility model, the positioning pin 2 can be connected in various ways. The positioning pin 2 can be fixedly connected to the central positioning block 1, and the subsequent connecting positioning block 3 can be sleeved on the central positioning block 1, so that the connecting positioning block 3 can rotate around the positioning pin 2.

[0034] Of course, in this utility model, the positioning pin 2 can be fixedly connected to the connecting positioning block 3, and then a corresponding central hole is set at the center position of the central positioning block 1 so that the positioning pin 2 can rotate in the central hole. In short, the positioning pin 2 is rotatably connected to at least one adjacent component, which provides a basis for the subsequent rotation of the magnet base 4.

[0035] In this utility model, the positioning structure is generally arranged on the partition 11.

[0036] The magnet base 4 is provided with an assembly hole 5; the positioning mechanism includes a center positioning block 1 inserted into the permanent magnet disk 10; the magnet base 4 is rotatably connected to the center positioning block 1, and the magnet base 4 can rotate relative to the center positioning block 1; this utility model discloses an installation device for assembling permanent magnets; this utility model, through the cooperative use of the magnet base 4 and the positioning mechanism, can assist in the installation and assembly of permanent magnets on the permanent magnet disk 10.

[0037] In addition, the mounting hole 5 on the magnet base 4 of this utility model can be used to limit the placement of the permanent magnet on the permanent disk 10, so as to better ensure the accuracy of the placement of the permanent magnet on the permanent disk 10.

[0038] In addition, the central positioning block 1 in this utility model is mainly used to limit the placement of the permanent magnet on the permanent disk 10, and at the same time to limit the position of the permanent magnet, so as to ensure that the permanent magnet is stably placed on the permanent disk 10.

[0039] In this utility model, the positioning structure mainly includes a magnet base 4, which is essentially a block structure with an assembly hole 5. In subsequent use, the permanent magnet to be installed is arranged in the magnet base 4 and falls into the corresponding slot of the permanent magnet disk 10 through the assembly hole 5, thereby realizing the assembly and installation of the permanent magnet on the permanent magnet disk 10.

[0040] The magnet base 4 can rotate, and this design allows multiple permanent magnets to be installed on the circumference of the permanent magnet disk 10 with just one magnet base 4.

[0041] In this utility model, the limiting function of the assembly hole 5 can ensure that the permanent magnet is placed accurately on the permanent magnet disk 10, which is especially important for permanent magnet assembly scenarios with high precision requirements.

[0042] In this utility model, the positioning mechanism includes a central positioning block 1. In actual arrangement, the central positioning block 1 is located at the central hole in the middle of the permanent magnet and is arranged on the partition 11.

[0043] In this utility model, the positioning pin 2 is connected to the central positioning block 1; the central positioning block 1 is mainly a cylindrical frustum structure, and its outer surface is mainly used for the placement and positioning of the permanent disk 10. In subsequent use, the permanent disk 10 is equivalent to being fitted onto the central positioning block 1, and the central positioning block 1 plays a good central positioning role for the permanent disk 10.

[0044] In addition, in this utility model, both the positioning pin 2 and the connecting positioning block 3 are arranged on the central positioning block 1. The horizontal projection of the central positioning block 1 is circular, and the center of the central positioning block 1 is connected to the positioning pin 2. There are various connection methods, which can be selected according to needs.

[0045] Furthermore, in this utility model, the magnet base 4 is connected to the central positioning block 1 through a rotating mechanism; the rotating mechanism includes a positioning pin 2 connected to the central positioning block 1; the magnet base 4 can rotate around the central axis of the positioning pin 2; the positioning pin 2 acts as a rotation fulcrum, which can conveniently limit the rotation trajectory and route of the magnet base 4.

[0046] In this utility model, the rotating mechanism mainly serves as a rotation center, which facilitates the limitation of the rotation trajectory and path of the magnet base 4; the rotating mechanism in this utility model includes a positioning pin 2; the positioning pin 2 is connected to the central positioning block 1, and in this utility model, the positioning pin 2 is actually inserted into the central positioning block 1.

[0047] Furthermore, in this utility model, the magnet base 4 is connected to the positioning pin 2 via a connecting mechanism; the connecting mechanism includes two spaced-apart connecting beams 7, the ends of which are connected to the positioning pin 2 via connecting positioning blocks 3; the magnet base 4 is connected to the positioning pin 2 via the connecting mechanism, and the magnet base 4 can rotate around the central axis of the positioning pin 2; the connecting mechanism plays a good bridging and connecting role, facilitating the connection between the magnet base 4 and the positioning pin 2, while also ensuring the spacing between them; it can be used in conjunction with the permanent magnet disk 10 to be installed.

[0048] In this invention, the positioning pin 2 is connected to the center of the central positioning block 1, and the connecting mechanism is connected to the positioning pin 2 via the connecting positioning block 3. The connecting mechanism includes two spaced-apart connecting beams 7, the ends of which are connected to the positioning pin 2 via the connecting positioning block 3. The two connecting beams 7 are spaced-apart and inserted into the magnet base 4. The two connecting beams 7 cooperate with each other to prevent the magnet base 4 from rotating relative to the connecting mechanism, thus providing a good limiting effect.

[0049] Meanwhile, in this utility model, the connecting positioning block 3 serves two purposes: firstly, to connect the two connecting beams 7, and secondly, to act as a rotating block. The connecting positioning block 3 is essentially connected to the positioning pin 2. The connecting positioning block 3 and the positioning pin 2 can rotate relative to each other or synchronously. Based on this design, the magnet seat 4 can be connected to the positioning pin 2, while also allowing the magnet seat 4 to rotate around the central axis of the positioning pin 2.

[0050] Furthermore, the magnet base 4 described in this utility model is provided with a limiting unit; the limiting unit mainly adds limiting parts around the assembly hole 5, which facilitates the subsequent arrangement and placement of the permanent magnet in the assembly hole 5.

[0051] Specifically, the limiting unit in this utility model includes two limiting mechanisms 6 spaced apart on both sides of the assembly hole 5; the two limiting mechanisms 6 cooperate with each other to limit the position of the permanent magnet on both sides, thereby better ensuring the stability of the permanent magnet's position within the magnet base 4.

[0052] In this utility model, each of the limiting mechanisms 6 includes a limiting block 61 disposed on the side of the magnet base 4 near the partition plate 11; the limiting block 61 is connected to an adjustment mechanism; in this utility model, the adjustment mechanism is mainly used to adjust the position of the limiting block 61, so as to make the limiting block 61 contact or detach from the permanent magnet, thereby facilitating the subsequent fall of the permanent magnet from the magnet block into the corresponding slot on the permanent magnet disk 10.

[0053] Furthermore, the adjustment mechanism in this invention includes a through rod 62 connected to the limiting block 61. The through rod 62 passes through the magnet base 4, and a toggle block 63 is provided at the end of the through rod 62 away from the limiting block 61. In this invention, the through rod 62 acts as a connecting rod and a linkage rod, facilitating subsequent control of the position of the limiting block 61. In this invention, by toggling or rotating the toggle block 63, the toggle block 63 drives the through rod 62 to rotate, and the through rod 62 drives the limiting block 61 connected to it to rotate, thereby causing the limiting block 61 to disengage from directly below the assembly hole 5, thus facilitating the subsequent assembly of the permanent magnet.

[0054] In normal use, the two adjustment mechanisms rotate synchronously to facilitate the smooth landing of the permanent magnet onto the permanent magnet disk 10.

[0055] Furthermore, in this utility model, the magnet base 4 is provided with a mounting groove 64 for arranging the limiting block 61. The mounting groove 64 is arranged at the edge of the assembly hole 5 and is connected to the assembly hole 5. The setting of the mounting groove 64 plays a good role in avoiding obstruction, facilitating the arrangement of the limiting block 61 at the lower end of the magnet block. At the same time, it is required that the thickness of the limiting block 61 is less than the depth of the mounting groove 64. This setting can prevent the limiting block 61 from being exposed, thereby preventing the limiting block 61 from protruding on the magnet base 4 and preventing the presence of the limiting block 61 from affecting the subsequent rotation and operation of the magnet base 4. It also prevents the protruding limiting block 61 from interfering with the operation of the permanent magnet disk 10.

[0056] Furthermore, the positioning structure in this utility model also includes a support slider 8 disposed on the connecting mechanism; the connecting mechanism passes through the support slider 8; the support slider 8 plays a good supporting and elevating role, which can well ensure the stability of the lateral arrangement position of the magnet seat 4, and at the same time, the support slider 8 and the connecting positioning block 3 can simultaneously provide longitudinal support and elevate the two connecting beams 7, ensuring the stability of the lateral arrangement of the positioning structure.

[0057] Furthermore, in this utility model, the connecting beam 7, the supporting slider 8, and the connecting positioning block 3 are all connected by a detachable connection method.

[0058] Specifically, the end of the connecting beam 7 is inserted into the side of the connecting positioning block 3, and a fastening bolt is inserted into the upper end of the connecting positioning block 3. The fastening bolt passes through the connecting positioning block 3 and can press against the corresponding connecting beam 7, thereby realizing the installation and fixation between the connecting beam 7 and the connecting positioning block 3.

[0059] Similarly, the connecting beam 7 is set through the supporting slider 8, and a fastening bolt is provided on the upper end face of the supporting slider 8. The fastening bolt is connected to the supporting slider 8, and at the same time, the fastening bolt on the supporting slider 8 can also press against the corresponding connecting beam 7, thereby realizing the connection and fixation between the connecting beam 7 and the supporting slider 8.

[0060] Meanwhile, the connection between the magnet base 4 and the connecting beam 7 can also be similar to that between the support slider 8 and the connecting beam 7. Based on this design, the position of the support slider 8 or the magnet block can be changed as needed, thereby enabling the assembly and positioning of permanent magnets on permanent disks 10 of different diameters.

[0061] Example:

[0062] This utility model discloses an installation device for assembling permanent magnets; it is mainly used for the auxiliary installation of permanent magnets of high-power, high-speed permanent magnet speed controllers on permanent magnet disks 10.

[0063] Specifically, it includes the following structure:

[0064] The components include a center positioning block 1, a positioning pin 2, a connecting positioning block 3, two connecting beams 7, a support slider 8, a magnet seat 4, an assembly hole 5, a limit block 61, a connecting rod 62, and a toggle block 63.

[0065] The present invention has a partition 11 arranged on the side of the permanent magnet disk 10 to be installed. A permanent magnet pressure plate 9 is provided on the side of the partition 11 away from the permanent magnet disk 10. In the present invention, the permanent magnet pressure plate 9 is arranged on the side of the partition 11 away from the positioning structure. The permanent magnet pressure plate 9 is a steel part and can be attracted and attracted by a permanent magnet.

[0066] In actual implementation, the distance between the permanent magnet disk 10 and the permanent magnet pressure plate 9 is adjusted by adjusting the bolts to control the impact force generated during the installation of the permanent magnet and avoid damage to the permanent magnet.

[0067] In this utility model, the distance between the permanent magnet pressure plate 9 and the permanent magnet disk 10 is adjusted according to the magnetic field strength of the permanent magnet.

[0068] The installation device for assembling permanent magnets disclosed in this utility model is made entirely of stainless steel or aluminum, and does not have an adsorption effect with the permanent magnet.

[0069] This invention allows for convenient and reliable installation of permanent magnets, improving safety and reliability.

[0070] In actual implementation: the center positioning block 1 is installed into the center hole of the permanent magnet disk 10, the connecting positioning block 3 is then inserted into the center positioning block 1 through the positioning pin 2, and the two connecting beams 7 fixed on the connecting positioning block 3 are connected. The connecting beams 7 can rotate around the center positioning block 1360 degrees, and the magnet base 4 can slide freely on the connecting beams 7. In this way, the permanent magnet can be installed at any position on the permanent magnet disk 10.

[0071] In actual assembly, different permanent disks 10 may have different central hole diameters. In this case, only the center positioning block 1 needs to be replaced with a matching size, and other parts do not need to be replaced. It has very high versatility.

[0072] In addition to having mounting holes 5 of the same size as the permanent magnet, the magnet base 4 is extended on one side. This allows it to cover the permanent magnet that has already been installed next to it when installing the permanent magnet, thus preventing the two adjacent permanent magnets from attracting each other and causing damage or personal injury.

[0073] During installation, the permanent magnet is placed into the assembly hole 5 of the magnet base 4. At this time, the lower limiting block 61 will support the permanent magnet to prevent it from falling. Rotate the positioning block and move the support slider 8 to align the permanent magnet with the hole on the permanent magnet disk 10. Move the upper toggle block 63 to open the lower limiting block 61. Under the action of gravity and the attraction of the lower permanent magnet pressure plate 9, the permanent magnet falls into the hole of the permanent magnet disk 10, completing the assembly of a magnet.

[0074] Repeat the above steps until all magnets are installed on disk 10 as required by the drawings.

[0075] Obviously, the specific implementation of this utility model is not limited to the above-mentioned methods. Any non-substantial improvements made using the inventive concept and technical solution of this utility model are within the protection scope of this utility model.
