Description

Technical Field

[0001] This utility model relates to the field of motor magnetic block assembly technology, and in particular to a magnetic block assembly device. Background Technology

[0002] Currently, motor magnets are assembled piece by piece manually. This method requires a lot of manpower, resulting in high labor costs. At the same time, manual assembly is very inefficient, takes a long time, and cannot achieve the required precision, resulting in a large number of defective products and significant waste of resources. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a magnetic block assembly device to solve the technical problem of low magnetic block assembly efficiency in the prior art.

[0004] This utility model is achieved using the following technical solution:

[0005] A magnetic block assembly device includes a drive mechanism, a lifting mechanism, a worktable, and a support. The worktable is fixed on the support, and the lifting mechanism is partially connected to the power mechanism. The worktable is arranged around the lifting mechanism. The lifting mechanism includes a push ring, a mold core, and one or more push bars. The push ring is connected to the drive mechanism. The mold core has a cylindrical structure, and one or more grooves are provided on the outer periphery of the mold core. The bottom of the push bar is disposed on the push ring, and the upper end of the push bar is disposed in the groove of the mold core. The push bar reciprocates up and down within the groove as driven by the drive mechanism.

[0006] Preferably, the lifting mechanism further includes a push ring lock and a retaining sleeve. The push ring has a flange on its outer periphery, and the bottom of the push bar is located on the flange. The push ring lock is located on the outer periphery of the bottom of the push bar to lock the push bar onto the push ring. The retaining sleeve is located on the outer periphery of the mold core to bind the push bar in the groove.

[0007] Preferably, it further includes a guide post, which is disposed on the bracket; the upper end of the guide post is fixedly connected to the mold core, and the lower end of the guide post is provided with teeth, on which nuts are fitted.

[0008] Preferably, there are two nuts, which are respectively disposed on both sides of the bracket.

[0009] Preferably, the upper end of the model is provided with a cavity, and a shaft positioning component is fixed inside the cavity; the shaft positioning component has a first shaft hole at its center.

[0010] Preferably, the first shaft hole has a shaft replacement part at its center, and the shaft replacement part has a second shaft hole at its center.

[0011] Preferably, the upper end face of the shaft positioning component is provided with a groove, and a positioning block and a spring are provided in the groove. The spring is located between the groove wall of the shaft positioning component and the positioning block. The end face of the other end of the positioning block is a slope. When the slope faces downward and the spring is in its natural state, the slope of the positioning block extends above the slide groove of the mold core.

[0012] Preferably, the worktable has a central circular hole, which is fitted around the outer periphery of the mold core. The upper surface of the worktable is provided with one or more feed slots, which lead to the central circular hole. When multiple feed slots are provided, they are arranged radially.

[0013] Preferably, an angle adjustment plate is provided between the workbench and the support. The angle adjustment plate is fixed on the support and has several arc-shaped through holes. The workbench is fixed to the angle adjustment plate by bolts, with one end of the bolt fixed on the workbench and the other end of the bolt fitted into the arc-shaped through holes.

[0014] Preferably, it also includes a cylinder connecting plate, which is connected between the output shaft of the drive mechanism and the push ring.

[0015] Compared to existing technologies, the advantages of this invention are as follows: This invention incorporates a mold core. Driven by a drive mechanism, a pusher bar within the mold core and a feeding groove surrounding it pushes a magnetic block adsorbed on the mold core into the motor housing, achieving automated assembly of the magnetic block, improving assembly efficiency, precision, and yield. Furthermore, by incorporating a pusher ring lock and a retaining sleeve, the pusher bar is better secured to the pusher ring and mold core, and the lock also ensures a more stable installation. Additionally, a guide post is provided on the support frame. The lower end of the guide post has teeth, and the upper end is fixedly connected to the mold core. An adjusting nut can adjust the vertical position of the guide post, thereby adjusting the height of the mold core. This allows for the assembly of magnetic blocks of the same structure but different heights, enhancing the applicability of the device. Finally, the shaft positioning component has a first shaft hole at its center. After the shaft of the motor to be magnetized is inserted into the first shaft hole, the motor can be quickly fixed to the mold core for the next magnetization assembly step, improving assembly efficiency. Furthermore, the first shaft hole has a shaft replacement part at its center, and the shaft replacement part has a second shaft hole at its center. By replacing the shaft replacement parts with different specifications, second shaft holes of different specifications can be obtained, thereby matching magneto motors with shafts of different specifications to be fed, enhancing the applicability of the device. Furthermore, by setting an angle adjustment plate with an arc-shaped through hole, the worktable can be finely adjusted relative to the angle adjustment plate with the central circular hole as the axis, allowing the feed groove to quickly align with the mold core's slide groove, improving the actual operability of the device.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0031] like Figure 1 and Figure 2 As shown, the magnetic block assembly device of this application includes a worktable 1, a support 2, a drive mechanism 3, a lifting mechanism 4, and a guide post 5. The worktable 1, drive mechanism 3, and guide post 5 are mounted on the support 2. Multiple radially distributed feed slots 11 are provided on the upper surface of the worktable. The drive mechanism 3 is a cylinder, with a pair of cylinders symmetrically arranged on both sides of the guide post 5. The lower end of the guide post 5 has a toothed screw structure, with a pair of nuts fitted onto the screw, one on each side separated by the support. The bottom of the lifting mechanism 4 is fixed to the guide post 5. An angle adjustment plate 6 is fixed to the support 2, and the worktable 1 is fixed to the angle adjustment plate. The motor 7 for assembling the magnetic block is positioned in the middle of the worktable.

[0032] Please refer to Figure 3 The lifting mechanism 4 includes a mold core 41, multiple push bars 42, push rings 44, push ring locks 43, and a retaining sleeve 45. The guide post 5 has a cylindrical structure, with its upper end fitted into the lower end of the mold core 41. The lower end of the guide post 5 has a toothed structure forming a lead screw. A nut 9 is provided on the lead screw, spaced apart from the bracket 2. Adjusting the upper nut allows for vertical height adjustment of the guide post 5, thereby adjusting the height of the mold core 41. If the cylinder stroke allows, placing a few small shims on top of the mold core allows for the installation of magnetic blocks for motors with different height requirements but the same structure. Nuts located under the bracket limit the rising height of the guide post 5, preventing excessive movement and detachment from the bracket. To enhance assembly stability, a cylinder connecting plate 9 is installed between the drive mechanism 3 and the lifting mechanism 4. The cylinder connecting plate 9 surrounds the guide post 5 and connects the cylinder output shaft to the push ring 44. The cylinder connecting plate 9 is fixed to the output shaft of the cylinder. The push ring is arranged around the guide post 5 and above the cylinder connecting plate 9, and is fitted into the cylinder connecting plate 9. A sleeve 51 is arranged around the guide post 5, located below the cylinder connecting plate 9. The sleeve 51 is fixed to the cylinder connecting plate 9 by screws, which enhances the structural stability of the entire magnetic block assembly device. The retaining sleeve 45 is arranged around the mold core 41 and is a ring structure. The retaining sleeve 45 is fixed below the worktable 1 and binds the push bar 42 in the mold core.

[0033] Please refer to Figure 3 and Figure 4 The push ring 44 has a circular ring structure with a flange on its outer periphery. The lower end of the push bar 42 is set on the flange of the push ring. A push ring lock 43, also a circular ring structure, surrounds the push ring and has a latch. The bottom end of the push bar also has a latch. The latches of the push ring lock and the push bar engage, thus locking the push bar onto the push ring. During assembly, the push ring lock is fixed to the cylinder connecting plate 9 with screws and is positioned around the push ring. The mold core 41 has a cylindrical structure. The upper diameter of the mold core 41 is larger, and the lower diameter is smaller. The lower end of the mold core 41 tapers towards the axis, forming the usable stroke space of the push ring 44. The mold core 41 is made entirely or partially of steel and has the function of attracting magnetic blocks. (Reference) Figure 5 The outer periphery of the mold core 41 is provided with multiple sliding grooves 411; the upper end of the pusher is located in the sliding groove 411 of the mold core and is bound by the sleeve 45. The cylinder connecting plate 9 moves upward under the push of the cylinder, and the cylinder connecting plate 9 drives the push ring 44 to move upward. The pusher 42 moves upward under the drive of the push ring 44, pushing out the magnetic block adsorbed on the sliding groove 411 and then installing it into the motor 7.

[0034] Please refer to Figures 5 to 8 The mold core 41 has a cavity at its upper end, and a shaft positioning component 412 is fixed inside the cavity. The shaft positioning component 412 has a flange at its upper end, with the flange portion engaging with the upper end of the mold core and the remaining portion engaging with the mold core. The shaft positioning component 412 has a first shaft hole at its center, which can be used to fix the shaft 72 of the motor to be assembled. In a preferred embodiment, a shaft replacement component 413 is provided at the center of the first shaft hole. The shaft replacement component 413 has a cylindrical structure, with a flange at its upper end. The lower end of the shaft replacement component 413 is inserted into the first shaft hole of the shaft positioning component 412, and the flange of the shaft replacement component 413 is engaged with the upper surface of the shaft positioning component 412. The shaft replacement component 413 has a second shaft hole at its center, which is used to fix the shaft 72 of the motor to be assembled. By replacing the shaft replacement component 413 with different sizes of second shaft holes, motors with different shaft 72 specifications can be matched, improving the applicability of this device and increasing its economic value. Please refer to [reference needed]. Figure 7 and Figure 8 The upper end face of the shaft positioning component 412 is provided with a groove 414, and a positioning block 415 and a spring 416 are provided in the groove 414. The spring 416 is disposed between the wall of the groove 414 and the positioning block 415. The end face of the other end of the positioning block 415 is a slope. When the slope faces downward and the spring 416 is in its natural state, the slope of the positioning block extends into the slide groove 411 of the mold core 41. The positioning block 415 is configured to be aligned with the position of one of the slide grooves.

[0035] The positioning block 415 is designed to work with the motor, and its working principle is as follows:

[0036] Please refer to Figure 9 This is a partially exploded view of the motor 7 with the magnetic blocks to be assembled. The motor 7 includes a housing 73, a magnetic retaining ring 71 for assembling the magnetic blocks, and a shaft 72. The magnetic retaining ring 71 has several slots for assembling the magnetic blocks. (Reference) Figure 7-9 When installing the motor 7 with magnetization, the motor shaft 71 is inserted into the second shaft hole of the shaft replacement part 413 and fixed. Due to its fixed position relative to the shaft 72, the magnetic retaining ring 71 is automatically positioned above the mold core. Slightly rotating the motor 7 causes the positioning block 415 to engage with one of the slots of the magnetic retaining ring 71. In the initial design, the width of the positioning block 415 and the width of the slot are set to be the same, ensuring a seamless connection after engagement. The positioning block 415 is pre-aligned with the position of the sliding groove. Rotating the motor 7, when the slot of the magnetic retaining ring 71 aligns with the positioning block 415, the slot of the magnetic retaining ring 71 also aligns with the position of the sliding groove. Thus, the positioning block allows for quick adjustment of the motor to the assembly position, improving the assembly efficiency of the magnetic blocks. (Reference) Figure 8 and Figure 12 When the push bar 42 pushes the magnetic block 10 upward, the magnetic block hits the inclined surface of the positioning block 415. The positioning block 415 contracts inward under force, compressing the spring 416, and retracts into the groove 414. The magnetic block continues to be installed upward in the slot of the magnetic ring 71. After the magnetic block is installed, the push bar moves downward driven by the push ring, and the positioning block 415 extends into the slot of the magnetic ring 71 under the action of the spring, keeping the magnetic ring 71 in the assembly position, preparing for the next motor to be equipped with a magnetic block. As a preferred embodiment, a fixing plate 417 is added to the upper end face of the shaft positioning member 412. The fixing plate 417 limits the positioning block 415 in the groove 414. At the same time, by changing the fixing plate 417 of different thicknesses, the height between the motor and the mold core can be adjusted. This allows for the installation of magnetic blocks for motors with the same structure but different magnetic block height requirements, improving the applicability of the magnetic block assembly device and increasing its economic value. To make the motor position more stable, a movable clamp or baffle can be added above the motor to fix its position and prevent the magnetic block from pushing the motor out of its original mounting position when assembling the magnetic block.

[0037] Please refer to Figure 10 The worktable 1 has a central circular hole that fits around the outer periphery of the mold core 41. Multiple feed slots 11 are provided on the upper surface of the worktable, arranged radially. Each feed slot 11 leads to the central circular hole and aligns with the sliding groove 411 of the mold core. Magnetic blocks that are attracted together are placed in the feed slots. The innermost magnetic block is attracted to the wall of the sliding groove 411. When the innermost magnetic block is pushed up by a pusher bar, the adjacent magnetic blocks continue to be attracted to the sliding groove. (Reference) Figure 1 and Figure 8 As a preferred option, a magnetic limiting plate 46 is also provided above the worktable around the mold core. The magnetic limiting plate 46 is fixed on the worktable to limit the magnetic block in the feed groove, so as to prevent the innermost magnetic block from moving and causing the adjacent magnetic blocks to move.

[0038] Please refer to Figure 1 , Figure 2 as well as Figure 11 An angle adjustment plate 6 is also provided between the workbench 1 and the support 2. The angle adjustment plate 6 is fixed on the support 2. An arc-shaped through hole 61 is provided on each of the four corners of the angle adjustment plate 6. The workbench 1 is provided with bolts. The bolts pass through the workbench and are assembled in the arc-shaped through holes to fix the workbench 1 on the angle adjustment plate.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
