Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for magnetic ring processing, specifically to a magnetic ring dotting and mounting shaft tooling. Background Technology

[0002] The magnetic ring is a key component of the motor rotor assembly. The magnetic ring and the motor shaft work together to form the motor rotor assembly. When the motor is energized, the stator coils drive the motor shaft to rotate through the magnetic ring, thereby realizing power output.

[0003] After the magnetic ring is machined, the motor shaft needs to be assembled into the shaft hole of the magnetic ring to form the rotor assembly. When assembling the shaft, adhesive needs to be applied to the motor shaft first, and then the adhesive-coated motor shaft is inserted into the shaft hole of the magnetic ring. After the adhesive cures, the magnetic ring and the motor shaft can be fixed together.

[0004] Currently, there are two difficulties in the shaft mounting process:

[0005] 1. When inserting the motor shaft into the magnetic ring shaft hole, since the shaft hole is a through hole, and the required insertion depth of the motor shaft into the magnetic ring is different for different specifications of rotor assemblies, the insertion depth of the motor shaft is generally controlled by special positioning tools, which is inefficient and difficult to operate.

[0006] Second, the adhesive requires a certain amount of time to cure. The current operating procedure is as follows: first, a special positioning tool is used to control the insertion depth of the motor shaft. After the motor shaft is inserted, it is then moved to the corresponding transfer box to allow the adhesive to cure. This method requires material transfer after the magnetic ring is installed (i.e., the shaft is inserted at the first station and then moved to the second station to wait for the adhesive to cure), which is inconvenient and inefficient. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a magnetic ring dispensing shaft placement fixture. By adjusting the positioning mechanism, users can adjust the distance between the bottom surface of the magnetic ring placement cylinder and the bottom of the fixing hole (i.e., the distance between the bottom of the movable plate and the upper surface of the fixed base) according to actual depth requirements. This allows for flexible adjustment of the insertion depth of the motor shaft into the magnetic ring's inner hole, meeting the assembly needs of different specifications and requirements. It solves the problem that current methods typically rely on dedicated positioning tools to control the insertion depth of the motor shaft, resulting in low efficiency and high operational difficulty.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a magnetic ring dotting and mounting shaft fixture, comprising a fixed base, a movable plate on the fixed base, a plurality of fixed holes arranged in a matrix on the fixed base, a shaft hole at the bottom center of each fixed hole, magnetic ring placement cylinders arranged in a matrix on the movable plate corresponding to each fixed hole, a clearance hole matching the shaft hole at the bottom center of all magnetic ring placement cylinders, and an adjustment and positioning mechanism for adjusting the insertion depth of the motor shaft into the inner hole of the magnetic ring between the fixed base and the movable plate.

[0009] Preferably, the adjusting positioning mechanism includes a positioning rod disposed on a fixed base, sliding rods disposed at the four corners of the fixed base, a first through hole provided on the movable plate to match the positioning rod, a second through hole provided at the four corners of the movable plate to match the sliding rod, and a fixing mechanism disposed on one side of the second through hole.

[0010] Preferably, the fixing mechanism includes a fixing pin disposed on one side of the first through hole, a fixing block rotatably connected to the fixing pin, and a fixing groove matching the sliding rod body provided on the fixing block.

[0011] Preferably, the positioning rod has scale lines on its body.

[0012] Preferably, the inner wall of the fixing groove is provided with anti-slip texture.

[0013] Preferably, one end of the fixing block is rotatably connected to the fixing pin, and the other end of the fixing block extends with a handle.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model proposes a magnetic ring dotting assembly shaft placement fixture. By adjusting the positioning mechanism, the user can adjust the distance between the bottom surface of the magnetic ring placement cylinder and the bottom of the fixed hole (i.e., the distance between the bottom of the movable plate and the upper surface of the fixed base) according to actual depth requirements. This allows for flexible adjustment of the depth to which the motor shaft is inserted into the inner hole of the magnetic ring, thereby meeting assembly requirements of different specifications and specifications. This not only improves the versatility of the fixture but also greatly enhances its flexibility and efficiency in actual production applications.

[0015] Additional aspects and advantages of this invention will be set forth in the central part of the description which follows, and some will be obvious from the description or may be learned by practice of the invention. Attached Figure Description

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0023] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a magnetic ring dotting and mounting shaft fixture includes a fixed base 1, a movable plate 2 on the fixed base 1, a plurality of fixed holes 3 arranged in a matrix on the fixed base 1, a shaft hole 4 at the bottom center of each fixed hole 3, magnetic ring placement cylinders 5 arranged in a matrix on the movable plate 2 corresponding to each fixed hole 3, and clearance holes 7 at the bottom center of all magnetic ring placement cylinders 5 matching the shaft holes 4. An adjustment and positioning mechanism 6 is provided between the fixed base 1 and the movable plate 2 for adjusting the depth of the motor shaft inserted into the inner hole of the magnetic ring.

[0024] The mounting base 1 has mounting holes 3 arranged in a matrix. A shaft hole 4 is opened at the bottom center of each mounting hole 3 to provide a channel for the insertion of the motor shaft.

[0025] The movable plate 2 also has several magnetic ring placement cylinders 5 arranged in a matrix. The number and position of these magnetic ring placement cylinders 5 correspond one-to-one with the fixing holes 3 and can be embedded inside the fixing holes 3. Each magnetic ring placement cylinder 5 has a clearance hole 7 at the bottom center. The size and shape of these clearance holes 7 match the shaft hole 4 on the fixing seat 1, so that when the motor shaft passes through, it can be directly inserted into the bottom of the shaft hole 4.

[0026] The specific operating procedure is as follows:

[0027] 1. Place the movable plate 2 on the fixed base 1 so that all the magnetic ring placement cylinders 5 are inserted into the fixed holes 3 one by one.

[0028] 2. Place the magnetic ring inside the magnetic ring placement cylinder 5, with the end of the magnetic ring contacting the bottom of the magnetic ring placement cylinder 5, so that the magnetic ring is fixed inside the magnetic ring placement cylinder 5.

[0029] 3. Insert the motor shaft with the glue applied into the inner hole of the magnetic ring, pass through the clearance hole 7 and insert into the inside of the shaft hole 4. At this time, the top of the motor shaft is in contact with the bottom of the shaft hole 4.

[0030] 4. After insertion, temporarily store the workpiece in the tooling until the glue cures, then remove all rotor assemblies at once.

[0031] To further enhance the flexibility and adaptability of the tooling, an adjustment and positioning mechanism 6 is installed between the fixed base 1 and the movable plate 2. This allows the user to adjust the distance between the bottom surface of the magnetic ring placement cylinder 5 and the bottom of the fixed hole 3 (i.e., the distance between the bottom of the movable plate 2 and the upper surface of the fixed base 1) according to the actual depth required for the motor shaft to insert into the inner hole of the magnetic ring. This allows for flexible adjustment of the depth at which the motor shaft is inserted into the inner hole of the magnetic ring, thereby meeting the assembly requirements of different specifications and specifications. This not only improves the versatility of the tooling but also greatly enhances its flexibility and efficiency in actual production applications.

[0032] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the adjusting positioning mechanism 6 includes a positioning rod 61 set on the fixed base 1, sliding rods 62 set at the four corners of the fixed base 1, a first through hole 63 matching the positioning rod 61 set on the movable plate 2, a second through hole 64 matching the sliding rod 62 set at the four corners of the movable plate 2, and a fixing mechanism 65 set on one side of the second through hole 64.

[0033] Positioning rods 61 are mounted on the fixed base 1 to ensure stable guidance of the movable plate 2 during movement. To further enhance the stability and adjustment flexibility of the movable plate 2, sliding rods 62 are also provided at the four corners of the fixed base 1. These sliding rods 62 not only provide additional support for the movable plate 2 but also allow for a certain range of adjustment in the vertical direction. Correspondingly, second through holes 64 matching the sliding rods 62 are provided at the four corners of the movable plate 2, allowing the movable plate 2 to slide smoothly along the sliding rods 62, achieving fine-tuning of its height.

[0034] A fixing mechanism 65 is provided on one side of the second perforation 64. This allows the user to lock the movable plate 2 at the required height after adjusting its position, preventing accidental movement during operation and ensuring assembly accuracy and stability.

[0035] When it is necessary to adjust the depth of the motor shaft inserted into the inner hole of the magnetic ring, the movable plate 2 slides vertically on the sliding rod 62 on the fixed base 1 to adjust the distance between the bottom surface of the movable plate 2 and the upper surface of the fixed base 1. The required height is determined by the positioning rod 61. Finally, the fixing mechanism 65 is used to lock the movable plate 2 on the sliding rod 62 to complete the adjustment.

[0036] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the fixing mechanism 65 includes a fixing pin 651 disposed on one side of the second through hole 64, a fixing block 652 rotatably connected to the fixing pin 651, and a fixing groove 653 that matches the sliding rod 62 is provided on the fixing block 652.

[0037] Specifically, the fixing mechanism 65 ensures the stable locking of the movable plate 2 after it has been adjusted to the ideal position. The fixing mechanism 65 mainly consists of three parts: a fixing pin 651, a fixing block 652, and a fixing groove 653. The fixing mechanism 65 is located on one side of the second through hole 64 on the movable plate 2. This ensures that the fixing mechanism 65 can fully perform its fixing function while avoiding interference with other parts of the tooling, thus guaranteeing the compactness and coordination of the overall structure.

[0038] One end of the fixing pin 651 is connected to the movable plate 2, and the other end serves as the axis for the rotational connection of the fixing block 652. This allows the fixing block 652 to rotate freely within a certain range, making it convenient for users to adjust its position according to actual needs to adapt to different fixing requirements.

[0039] One end of the fixing block 652 is connected to the fixing pin 651 via a rotatable connection, while the other end has a fixing groove 653 that matches the sliding rod 62. This allows the fixing block 652 to rotate so that the fixing groove 653 moves away from or close to the sliding rod 62, thereby releasing or locking the sliding rod 62.

[0040] The inner wall of the fixing groove 653 is usually specially treated to increase the friction between it and the sliding rod 62, preventing the fixing block 652 from sliding or loosening during the fixing process. At the same time, the shape and size of the fixing groove 653 are also matched with the sliding rod 62, ensuring a tight fit and a stable connection between the two.

[0041] Combination Figure 1 , Figure 2 and Figure 4 As shown, the positioning rod 61 has scale lines on its body.

[0042] Specifically, these scale lines are clearly and evenly distributed on the surface of the positioning rod 61, providing users with an intuitive visual reference. When it is necessary to adjust the height of the movable plate 2, the user can precisely control the distance the movable plate 2 slides along the sliding rod 62 according to the indication of the scale lines, thereby achieving fine-tuning of the height.

[0043] The presence of scale lines not only greatly improves the accuracy of adjustment but also makes the adjustment process more intuitive and easier to operate. Users do not need to rely on additional measuring tools; they can quickly and accurately determine the required position of the movable plate 2 using only the scale lines, thereby greatly improving work efficiency.

[0044] The scale lines also serve a marking function. When using the tooling for assembly multiple times, users can mark specific scale line positions on the positioning rod 61 based on previous experience or process requirements, so that they can quickly find and adjust to that position in subsequent assembly, further improving the reusability and accuracy of the tooling.

[0045] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the inner wall of the fixing groove 653 is provided with anti-slip texture.

[0046] Specifically, in order to increase the friction between the fixed groove 653 and the sliding rod 62 and prevent the movable plate 2 from moving unexpectedly due to vibration or external force during assembly, the inner wall of the fixed groove 653 is provided with anti-slip texture.

[0047] These anti-slip patterns are distributed in a fine, dense, and uniform manner on the inner wall surface of the fixing groove 653, which not only increases the contact area but also effectively improves the friction by changing the physical morphology of the surface. When the fixing block 652 slides along the sliding rod 62 to the locked position, the anti-slip patterns will fit tightly against the sliding rod 62, forming a solid "defense line" to ensure that the movable plate 2 remains stable in the vertical direction.

[0048] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, one end of the fixing block 652 is rotatably connected to the fixing pin 651, and the other end of the fixing block 652 extends to a handle 654.

[0049] Specifically, one end of the fixing block 652 is rotatably connected to the fixing pin 651, allowing the fixing block 652 to rotate freely within a certain range, so that the fixing block 652 moves away from or clamps the sliding rod 62, thereby fixing or releasing the sliding rod 62.

[0050] A handle 654 extends from the other end of the fixing block 652. The design of this handle 654 fully considers the user's comfort and convenience during use. It not only provides the user with an easy-to-grip and operating point of force, but also ensures, through its reasonable size and shape, that the user can easily apply force when rotating and pushing the fixing block 652, and that it is not easy to slip off.

[0051] In actual operation, the user only needs to hold the handle 654 and gently rotate the fixing block 652 to disengage the fixing groove 653 from the sliding rod 62. Then, by pushing the movable plate 2 along the sliding rod 62 to the locked position, gently rotating the fixing block 652 will re-lock the fixing groove 653 onto the sliding rod 62, thus completing the fixation of the movable plate 2. The whole process is simple and quick, greatly saving the user's time and effort.

[0052] This invention represents a preferred embodiment of the present invention, but its scope of protection is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this invention, based on the technical solution and inventive concept of this invention, shall be covered within the scope of protection of this invention.
