Description

Technical Field

[0001] This invention relates to the technical field of motor processing, and more particularly to an assembly fixture. Background Technology

[0002] In the permanent magnets of an electric motor, there is a type of tile-shaped magnetic sheet called a motor magnetic tile. Its function is to act as a constant magnetomotive force source within the motor, thereby converting mechanical energy into electrical energy using the principle of electromagnetic induction. During the assembly and manufacturing of an electric motor, the magnetic tiles are typically assembled using specialized fixtures.

[0003] In the prior art, the assembly fixture includes a constraint post, a constraint body, and a limiting post. The constraint body is disposed inside the constraint post, and multiple constraint spaces for inserting magnets are formed on the inner wall of the constraint post. The limiting post is inserted into the constraint post to ensure that the top walls of the multiple magnets are flush. When assembling magnets, the fixture first inserts the limiting post into the constraint post, then inserts the multiple magnets into the constraint spaces in sequence, finally removes the limiting post from the constraint post and inserts the rotor into the constraint post, then presses down the constraint post and moves the rotor relative to the magnets to insert the magnets into the corresponding slots on the rotor, thus completing the installation of the magnets.

[0004] However, in the above process, when the rotor is inserted into the constraint column, it is necessary to ensure that the slots on the rotor correspond to the magnets. At this time, there is a certain gap between the magnets and the rotor and both are located inside the constraint column, making it difficult to determine the relative position between them. It takes a lot of time to complete the positioning, which results in a time-consuming and inefficient assembly process. Summary of the Invention

[0005] The purpose of this invention is to provide an assembly fixture that solves the problem in the prior art that the positioning of the magnetic tile and the rotor is difficult during the magnetic tile assembly process, resulting in long assembly time and low efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An assembly fixture for mounting motor magnets includes a positioning component, a pushing component, and a pushing member. The positioning component has a positioning groove for mounting the magnet and corresponding to an outer rotor assembly. The pushing component is slidably connected within the positioning component, and the positioning groove has a corresponding groove into which the pushing component at least partially extends, the portion of the pushing component extending into the positioning groove abutting against the magnet. The pushing member is connected to the pushing component and is used to push the pushing component to slide, thereby pushing the magnet away from the positioning groove and into the outer rotor assembly for fixation.

[0008] Optionally, the positioning component includes: a positioning cylinder, the pushing component being slidably connected inside the positioning cylinder; and at least two protruding ribs, spaced apart on the outer side wall of the positioning cylinder, with the positioning groove formed between two adjacent protruding ribs, and the sliding groove penetrating the bottom wall of the positioning groove.

[0009] Optionally, the cross-section of the rib is trapezoidal and its narrow side is fixedly connected to the outer wall of the positioning cylinder.

[0010] Optionally, a fixing hole is provided in the positioning groove, and a fixing part for fixing the magnetic tile is provided in the fixing hole.

[0011] Optionally, multiple ribs are provided, and the multiple ribs are arranged circumferentially around the positioning cylinder and distributed at intervals to form multiple positioning grooves.

[0012] Optionally, the positioning assembly further includes a connecting cylinder disposed on the bottom wall of the positioning cylinder, wherein the outer diameter of the connecting cylinder is smaller than the outer diameter of the positioning cylinder, so as to guide the positioning cylinder into the outer rotor assembly.

[0013] Optionally, the pushing component includes: a pushing disk slidably connected within the positioning component; and a push rod disposed on the pushing disk and extending radially outward along the pushing disk, the push rod corresponding to the sliding groove, the push rod passing through the sliding groove and extending into the positioning groove to abut against the magnetic tile.

[0014] Optionally, the pushing component includes a connecting rod, the first end of which is fixedly connected to the pushing assembly.

[0015] Optionally, the pusher further includes a handle fixed to the second end of the link away from the push assembly, the cross-sectional area of ​​the handle being larger than the cross-sectional area of ​​the link.

[0016] Optionally, the assembly fixture further includes a cover plate disposed on the positioning assembly, and the connecting rod passes through the cover plate and is slidably connected to the cover plate.

[0017] Optionally, the pusher further includes a limiting member, which is sleeved on the connecting rod and abuts against the top wall of the pusher assembly.

[0018] Optionally, the outer rotor assembly includes: an outer rotor housing, the inner wall of which is provided with an adhesive layer for bonding with the magnetic tile; and an outer rotor end cap disposed on the outer rotor housing, the outer rotor end cap being provided with a mounting groove for inserting the magnetic tile.

[0019] The beneficial effects of this invention are:

[0020] By using a positioning component, multiple magnetic tiles can be installed simultaneously in the positioning slots. The positioning component is then inserted into the already positioned outer rotor assembly, allowing the positioning slots to quickly align with the outer rotor assembly. A pushing component then moves the pushing assembly within a groove, pushing the magnetic tile out of the positioning slot and into the outer rotor assembly. Once the magnetic tile is fixed, the positioning component is removed from the outer rotor assembly, completing the installation of multiple magnetic tiles. This method quickly positions the magnetic tiles to the outer rotor assembly during installation, facilitating rapid insertion and effectively reducing assembly difficulty, saving time, and improving efficiency.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0032] This invention provides an assembly fixture for installing motor magnets.

[0033] Figure 1 This is a schematic diagram of the assembly fixture in some embodiments of the present invention. Figure 2 This is a schematic diagram of the positioning and pushing components in the assembly fixture in some embodiments of the present invention. (Refer to...) Figure 1 and Figure 2 As shown, the assembly fixture includes a positioning component 200, a pushing component 300, and a pushing component 400. The positioning component 200 has a positioning groove 201 for mounting the magnet 500 and corresponding to the outer rotor assembly 600.

[0034] The push component 300 is slidably connected within the positioning component 200. The positioning groove 201 is correspondingly provided with a sliding groove 202 into which at least part of the push component 300 extends. The portion of the push component 300 extending into the positioning groove 201 abuts against the magnetic tile 500. The pusher 400 is connected to the push component 300 and is used to push the push component 300 to slide, thereby pushing the magnetic tile 500 away from the positioning groove 201 and into the outer rotor assembly 600 for fixation.

[0035] Specifically, the positioning component 200 is generally elongated, with the aforementioned positioning groove 201 provided on its outer side wall. The positioning groove 201 extends vertically and is open at its lower end to facilitate the insertion and removal of the magnetic tile 500. One or more positioning grooves 201 can be provided. When multiple grooves are provided, they can be distributed at intervals along the circumference of the cover plate 100. The specific number of positioning grooves 201 can be designed according to the actual application scenario, and this invention does not limit this number.

[0036] The positioning component 200 is hollow to facilitate the installation of the pushing component 300, which can slide vertically to push the magnetic tile 500 through the slide groove 202. The pushing member 400 is slidably connected to the cover plate 100 and extends partially into the positioning component 200 to connect with the pushing component 300. The pushing member 400 can be elongated to facilitate the operator's gripping and pushing.

[0037] When assembling the magnetic tile 500, the magnetic tile 500 can be installed in the positioning groove 201 by setting the positioning component 200, and then the positioning component 200 is inserted into the already placed outer rotor component 600, so that the positioning groove 201 can quickly correspond to the outer rotor component 600.

[0038] The pusher 400 moves the pusher assembly 300, causing it to slide within the slide groove 202. This pushes the magnetic tile 500 out of the positioning groove 201 and into the outer rotor assembly 600. Once the magnetic tile 500 is fixed, the positioning assembly 200 is removed from the outer rotor assembly 600, completing the installation of the magnetic tile 500. Thus, during the installation of the magnetic tile 500, the outer rotor assembly 600 does not need to move. The positioning assembly 200 easily positions the magnetic tile 500 within the outer rotor assembly 600, facilitating quick insertion and effectively reducing assembly difficulty, saving assembly time, and improving assembly efficiency.

[0039] Compared to inserting the magnetic tile 500 into the rotor by pressing down the constraint column, the present invention uses the pusher 400 to push the push assembly 300 to move and insert the magnetic tile 500 into the outer rotor assembly 600. This pushing process is more labor-saving and convenient, and can effectively reduce the workload of operators.

[0040] Figure 3 The image shown is a partial sectional view of an assembly fixture in some embodiments of the present invention. (Refer to...) Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the positioning component 200 includes a positioning cylinder 210 and at least two protruding ribs 220. The pushing component 300 is slidably connected inside the positioning cylinder 210. At least two protruding ribs 220 are spaced apart on the outer side wall of the positioning cylinder 210, and a positioning groove 201 is formed between two adjacent protruding ribs 220. A sliding groove 202 is provided through the bottom wall of the positioning groove 201.

[0041] Specifically, the positioning cylinder 210 is elongated, open at both ends and hollow inside. The lower side of the positioning cylinder 210 is used to insert into the outer rotor assembly 600. The outer wall of the pushing assembly 300 slides against the inner wall of the positioning cylinder 210.

[0042] The rib 220 extends along the axial direction of the positioning cylinder 210 and is fixed to the outer wall of the positioning cylinder 210 by welding or bonding. It can also be formed by integral molding. Alternatively, slots can be directly machined on the outer wall of the positioning cylinder 210 to form the rib 220 and the positioning groove 201. The specific design can be based on the actual processing difficulty, and this invention does not impose any specific limitations.

[0043] When assembling the magnetic tile 500, first insert each magnetic tile 500 into the corresponding positioning groove 201. Then, simply insert the positioning cylinder 210 into the outer rotor assembly 600 and make the positioning groove 201 correspond to the outer rotor assembly 600. The magnetic tile 500 can then be inserted into the outer rotor assembly 600 by moving the pushing assembly 300.

[0044] Figure 4 This is a horizontal sectional view of a positioning component in an assembly fixture in some embodiments of this application. (Refer to...) Figure 4 As shown, in some embodiments of the present invention, the cross-section of the rib 220 is trapezoidal and its narrow side is fixedly connected to the outer wall of the positioning cylinder 210. Specifically, the trapezoidal cam causes the two side walls of the positioning groove 201 to gradually approach each other, so that after the magnetic tile 500 is inserted into the positioning groove 201, the rib 220 can engage with the magnetic tile 500 to fix the magnetic tile 500 in the positioning groove 201, reducing the possibility of the magnetic tile 500 falling out.

[0045] Reference Figure 2 and Figure 3As shown, in some embodiments of the present invention, a fixing hole 230 is provided in the positioning groove, and a fixing part for fixing the magnetic tile 500 is provided in the fixing hole 230. Specifically, the fixing block 230 can be located on the bottom wall of the positioning groove 201, and the fixing part is embedded in the fixing hole 230. The fixing part can be a magnetic component or a magnetizable part to attract and fix the magnetic tile 500. It should be understood that the fixing part can also be made of an elastic material, such as a spring or an elastic pad. After the magnetic tile 500 is installed in the positioning groove 201, the spring or elastic pad can compress one side of the magnetic tile 500, so that the magnetic tile 500 abuts against the side of the protruding rib 220, thereby fixing the magnetic tile 500 in the positioning groove 201.

[0046] In some embodiments of the present invention, multiple ribs 200 are provided, and the multiple ribs 200 are arranged circumferentially around the positioning cylinder 210 and distributed at intervals to form multiple positioning grooves 201. Specifically, the opposite side surfaces between two adjacent ribs 220 serve as the two groove sidewalls of the positioning groove 201, and the bottom wall of the positioning cylinder 210 serves as the groove bottom wall of the positioning groove 201.

[0047] Reference Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the positioning assembly 200 further includes a connecting cylinder 240. The connecting cylinder 240 is disposed on the bottom wall of the positioning cylinder 210, and the outer diameter of the connecting cylinder 240 is smaller than the outer diameter of the positioning cylinder 210, so as to facilitate the insertion of the positioning cylinder 210 into the outer rotor assembly 600. Specifically, the connecting cylinder 240 is fixed to the bottom wall of the positioning cylinder 210, and the two can be integrally formed, welded, or fixed by bolts.

[0048] Reference Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the pushing component 300 includes a pushing disk 310 and a push rod 320. The pushing disk 310 is slidably connected within the positioning component 200. The push rod 320 corresponds to the sliding groove 202, passes through the sliding groove 202, and extends into the positioning groove 201 to abut against the magnetic tile 500.

[0049] Specifically, the peripheral wall of the pusher disk 310 slides against the inner wall of the positioning cylinder 210. Multiple push rods 320 can be provided, and their number can correspond to the number of positioning slots 201. The push rods 320 extend radially outward along the pusher disk 310 to pass through the slide groove 202 and extend into the positioning slot 201. The cross-section of the push rods 320 can be circular or square, and their lower side abuts against the top wall of the magnetic tile 500.

[0050] When the magnetic tile 500 is moved for installation, the pusher disk 310 slides in the positioning cylinder 210, thereby driving the push rod 320 to slide in the slide groove 202. When the push rod 320 slides, it pushes the magnetic tile 500 out of the positioning groove 201 and into the outer rotor assembly 600 to complete the installation of the magnetic tile 500.

[0051] Figure 5 This is a schematic diagram of the assembly fixture with a limiting element in some embodiments of the present invention. Figure 6 This is a partial sectional view showing that the assembly fixture in some embodiments of the present invention includes a limiting member. (Refer to...) Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the assembly fixture further includes a cover plate 100. The cover plate 100 is disposed on the positioning assembly 200. The pusher 400 includes a connecting rod 410 and a handle 420. The connecting rod 410 has a first end and a second end disposed opposite to each other, wherein the first end is fixedly connected to the pusher assembly 300, and the second end passes through the cover plate 100. The connecting rod 410 is slidably connected to the cover plate 100. The handle 420 is fixed to the second end of the connecting rod 410, and the cross-sectional area of ​​the handle 420 is larger than the cross-sectional area of ​​the connecting rod 410.

[0052] Specifically, the cover plate 100 is disc-shaped, and the positioning cylinder 210 of the positioning assembly 200 is set on the bottom wall of the cover plate 100. The two can be fixedly connected by fasteners such as bolts. The cover plate 100 abuts against the top of the protruding rib 220 to close the upper end of the positioning groove 201.

[0053] The connecting rod 410 is elongated, with its first end fixedly connected to the pusher plate 310, either by welding or by threaded connection. A through hole can be provided at the center of the cover plate 100, through which the connecting rod 410 passes, so that its first and second ends are located on opposite sides of the cover plate 100. The diameter of the through hole is larger than the diameter of the connecting rod 410 to facilitate sliding of the connecting rod 410.

[0054] The handle 420 is fixed to the second end of the connecting rod 410. The handle 420 has a large cross-sectional area so that the operator can move the connecting rod 410 by gripping the handle 420. During the movement, the connecting rod 410 can move the push plate 310. The handle 420 can also be equipped with friction pads or other structures to facilitate the operator to apply pressure by gripping the handle 420.

[0055] Reference Figure 5 As shown, in some embodiments of the present invention, the pusher 400 further includes a limiting member 430. The limiting member 430 is sleeved on the connecting rod 410 and located between the pusher assembly 300 and the cover plate 100.

[0056] Specifically, to accommodate magnetic tiles 500 of various sizes, the length of the positioning groove 201 can be designed according to the longest magnetic tile 500. However, when assembling magnetic tiles 500 of other lengths, the magnetic tile 500 may wobble within the positioning groove 201 because the length of the positioning groove 201 is greater than the length of the magnetic tile 500. By setting a limiting member 430 on the connecting rod 410, the cross-section of the limiting member 430 can be circular or square, or other shapes, such as multiple spaced uprights, as long as the top wall of the limiting member 430 abuts against the bottom wall of the cover plate 100 and the bottom wall of the limiting member 430 abuts against the top wall of the push plate 310. This limits the height of the push plate 310, thus limiting the height of the push rod 320 in the positioning groove 201.

[0057] When installing the magnetic tile 500, a suitable height limiting member 430 is selected and fitted onto the connecting rod according to the difference between the length of the magnetic tile 500 and the length of the positioning groove 201, so as to limit the push rod 320 at a specified height in the positioning groove 201. After the magnetic tile 500 is inserted into the positioning groove 201, its top wall will abut against the push rod 320, and its lower side will be attracted and fixed by the fixing part, thus successfully fixing the magnetic tile 500 in the positioning groove 201 and reducing the possibility of the magnetic tile 500 shaking.

[0058] Figure 7 This is a schematic diagram of the outer rotor assembly in the assembly fixture in some embodiments of the present invention. (Refer to...) Figure 7 As shown, in some embodiments of the present invention, the outer rotor assembly 600 includes an outer rotor housing 610 and an outer rotor end cap 620. The inner wall of the outer rotor housing 610 is provided with an adhesive layer for bonding with the magnetic tile 500. The outer rotor end cap 620 is disposed on the outer rotor housing 610, and the outer rotor end cap 620 is provided with a mounting groove 623 for inserting the magnetic tile 500.

[0059] Specifically, the outer rotor housing 610 is annular, with an inner diameter larger than the maximum outer diameter of the positioning component 200 to facilitate the insertion of the positioning component 200. The top wall of the outer rotor housing 610 extends inward to form a retaining edge, so as to facilitate the application of the adhesive layer to the inner sidewall of the outer rotor housing 610. The adhesive layer can be a quick-drying adhesive, and the specific type can be designed according to the actual application scenario. This invention does not limit the type.

[0060] The outer rotor end cover 620 is fixed to the bottom wall of the outer rotor housing 610. It includes an end cover frame 621 and a mounting sleeve 622. The end cover frame 621 is annular and fixed to the lower end face of the outer rotor housing 610. The mounting sleeve 622 is fixed to the top wall of the end cover frame 621 and extends into the outer rotor housing 610. The outer side wall of the mounting sleeve 622 abuts against the inner side wall of the outer rotor housing 610. The top wall of the mounting sleeve 622 is provided with a plurality of mounting grooves 623 corresponding to the positioning grooves 201. Both sides of the mounting grooves 623 are chamfered to facilitate the insertion of the magnetic tile 500.

[0061] When installing the magnet 500, first apply an adhesive layer to the inner wall of the outer rotor housing 610. Then, insert the positioning cylinder 210 with the magnet 500 installed into the outer rotor housing 610, ensuring that the connecting cylinder 240 abuts against the top wall of the mounting sleeve 622, with the positioning groove 201 corresponding to the mounting groove 623. Because the mounting groove 623 has a chamfer, the operator can easily insert the magnet 500 into the mounting groove 623 after pressing down the handle 420 and pushing it out of the positioning groove 201 via the push rod 320. After the magnet 500 is completely detached from the positioning groove 201, its side will adhere to the adhesive layer inside the outer rotor housing 610. Once the adhesive layer has hardened, the positioning cylinder 210 can be pulled out of the outer rotor housing 610, completing the assembly of the magnet 500.

[0062] During the assembly process, the outer rotor assembly 600 does not need to be moved, so the positioning groove 201 can be easily aligned with the mounting groove 623. The operator can easily push the magnetic tile 500 into the mounting groove 623 for fixed installation through the handle 420, thereby effectively simplifying the installation process of the magnetic tile 500, saving the time spent assembling the magnetic tile 500 and improving the assembly efficiency.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
