Description

Technical Field

[0001] This utility model relates to the field of motor installation, and in particular to a fixed installation structure for a rotary motor. Background Technology

[0002] Strip material is the raw material for manufacturing motor cores. The strip material is conveyed on the production mold of the core to realize the stamping and forming of each piece. In the current automatic stacking and riveting of cores, in order to improve the thickness difference of the core caused by the thickness difference of the stamping material, the blanking die is usually a rotating body. The blanking die is driven to rotate by a rotary motor. After each stamping, it rotates a certain angle, which ultimately effectively improves the uniformity of the core thickness.

[0003] A search revealed that Chinese patent CN201167271Y discloses a large-rotation mechanical protection device for an automatic riveting mold for motor cores. The device uses a servo motor to drive the rotating sleeve to rotate. The servo motor is mounted with a servo motor mounting plate, which is fixed to the lower mold. Synchronous pulleys are set on the output end of the servo motor and the rotating sleeve. The two synchronous pulleys are driven by a synchronous belt, so that the servo motor can drive the rotating sleeve to rotate.

[0004] However, since the servo motor is directly fixed on the lower mold, in actual use, when the mold needs to be repaired or the mold needs to be replaced to produce different product cores, the entire rotary motor needs to be removed, which is troublesome and inconvenient, and needs to be further improved.

[0009] Optionally, the side wall of the machine tool has a recessed platform, on which a fixing strip is fixedly installed. The fixing strip has mounting holes corresponding to the connecting holes, and the connecting screw passes through the connecting holes and is threaded into the mounting holes.

[0010] Optionally, a support bar is fixedly provided on the side wall of the machine tool, and a sliding groove is provided on the support bar along its length direction. The bottom end of the mounting frame has a sliding support end that is adapted to the sliding groove.

[0011] Optionally, a scraper is detachably connected to the bottom end of the sliding support end, and the bottom end of the scraper contacts the bottom wall of the sliding groove.

[0012] Optionally, one of the connecting holes is connected to and corresponding to the fixing hole, and the end of the connecting screw abuts against the end of the fixing bolt after being tightened.

[0013] Optionally, the mounting bracket is detachably connected to a support block, which is used to abut against the bottom of the adjustment plate to support it.

During installation, the support bar can provide auxiliary support for the entire mounting frame, which facilitates the subsequent operation of the fixing bolts. 3. The mounting bracket can be slidably adjusted along the support bar direction. Simultaneously, the height of the adjustment bracket on the mounting bracket can be adjusted vertically. This adjustment ensures the accuracy of the synchronous pulley position on the rotary motor, facilitating the transmission connection of the synchronous pulley. 4. The design of the tightening part facilitates the rotation of the fixing bolts. In actual use, a hex wrench can be used to drive the fixing bolts to achieve the connection and fixation. The support rod design provides auxiliary support for the fixing bolts and the entire mounting bracket, improving the overall structural stability. Furthermore, the support rod abutting against the tightening part acts as a circumferential limit, preventing the fixing bolts from rotating due to vibration during actual use, thus affecting the connection's stability and realizing the multi-purpose nature of the support rod.

[0020] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0021] A fixed mounting structure for a rotary motor, such as Figure 1 and Figure 2As shown, the system includes a machine base 2 for mounting the lower mold 1. A mounting bracket 4 for mounting the rotary motor 3 is installed on one side of the machine base 2. An adjusting plate 5 is vertically adjustable and fixedly mounted on the mounting bracket 4. The rotary motor 3 is vertically upward and fixed on the adjusting plate 5. A fixing bolt 6 is provided between the mounting bracket 4 and the machine base 2 to connect the two. The fixing bolts 6 are symmetrically arranged on both sides of the mounting bracket 4. In other embodiments, multiple fixing bolts 6 can be vertically spaced to further improve the connection strength. Both ends of the fixing bolts 6 have threaded ends. The machine base 2 and the mounting bracket 4 are provided with fixing holes 7 that are threaded to the threaded ends of the fixing bolts 6. At the same time, a support bar 8 is provided on the bottom side wall of the machine base 2 to provide vertical support for the mounting bracket 4. A synchronous wheel 9 for transmission is installed on the output end of the rotary motor 3. In actual use, a synchronous wheel 9 is also provided on the blanking die in the lower mold 1. Transmission is achieved by connecting the synchronous wheel 9 on the blanking die in the lower mold 1 with a synchronous belt.

[0022] like Figure 1 As shown, a tightening part 10 is integrally formed with the fixing bolt 6 in the middle. The tightening part 10 is in the shape of a regular hexagonal prism. In actual operation, the fixing bolt 6 can be rotated by the tightening part 10 to realize the disassembly or adjustment of the fixing bolt 6. The regular hexagonal prism shape of the tightening part 10 reduces slippage and also makes it easy to operate with a hex wrench.

[0023] In this way, the rotary motor 3 is first fixedly mounted on the mounting bracket 4 with the help of the adjusting plate 5. Then, the mounting bracket 4 is supported by the support bar 8 at the bottom, and then connected and fixed to the machine base 2 with the fixing bolts 6, thus achieving a good fixation of the mounting bracket 4. At this time, it is connected and fixed to the machine base 2 used to install the lower mold 1 with the mounting bracket 4. In this way, when the lower mold 1 needs to be disassembled for mold repair or replacement, there is no need to disassemble the rotary motor 3. Only the timing belt needs to be removed, which is simple and convenient and effectively improves the convenience of mold repair or replacement. Furthermore, the disassembly can be achieved by rotating the fixing bolt 6 to disengage the threaded end from the fixing hole 7, making the disassembly and assembly operation convenient and quick.

[0024] like Figure 1 and Figure 2As shown, the adjusting plate 5 has a groove 11 with its length direction facing downwards. A connecting screw 12 passes through the groove 11. At the same time, a connecting hole 13 is provided on the mounting bracket 4 corresponding to the groove 11 for connecting with the connecting screw 12. The connecting screw 12 passes through the groove 11 and is threaded into the connecting hole 13. The head 14 of the connecting screw 12 is wider than the width of the groove 11. In this way, the head 14 can press and fix the adjusting plate 5 during the tightening of the connecting screw 12, thus achieving the pressing and fixing of the adjusting plate 5. In actual use, when it is necessary to adjust the height of the adjusting plate 5 vertically, simply loosen the connecting screw 12, move the adjusting plate 5 up and down, and then tighten the connecting screw 12. The operation is simple and convenient.

[0025] like Figure 1 As shown, in this embodiment, one of the connecting holes 13 on the mounting bracket 4 is connected to and corresponding to the fixing hole 7. After the connecting screw 12 is tightened, its end abuts against the end of the fixing bolt 6. In this way, the connecting screw 12 can play an axial limiting role for the fixing bolt 6, thereby avoiding the situation where the fixing bolt 6 rotates due to vibration and moves axially, resulting in loosening. This further improves the connection firmness of the fixing bolt 6 and realizes the multi-purpose of the connecting screw 12.

[0026] like Figure 1 As shown, a recessed platform 15 is provided on one side wall of the machine base 2. A fixing strip 16 is fixedly installed on the platform 15. The fixing strip 16 has mounting holes 17 corresponding to the connecting holes 13. In actual use, the connecting screw 12 passes through the mounting bracket 4 and is threaded into the mounting holes 17 of the fixing strip 16. In this way, the connecting screw 12 not only achieves the pressing and fixing of the adjusting plate 5, but also helps to fix the mounting bracket 4 on the machine base 2, further improving the installation firmness and stability of the mounting bracket 4, and can be achieved without additional fasteners.

[0027] like Figure 1 As shown, a groove 18 is provided at the top of the support bar 8, and the bottom end of the mounting bracket 4 has a sliding support end 19 that is adapted to the groove 18. The initial positioning can be achieved by the insertion and cooperation of the sliding support end 19 and the groove 18. During actual installation, the mounting bracket 4 will not fall or tilt after being placed on the support bar 8, which facilitates the subsequent installation of the fixing bolts 6. The sliding connection between the mounting bracket 4 and the support bar 8 allows the mounting bracket 4 to be horizontally slidably adjusted on the machine base 2 in actual use, ensuring that the fixing bolts 6 can be properly connected to the fixing holes 7 on the machine base 2.

[0028] like Figure 1As shown, a scraper 20 is detachably connected to the bottom end of the sliding support end 19. The scraper 20 can be connected to the sliding support end 19 by screws. The scraper 20 abuts against the bottom wall of the slide groove 18. The slide groove 18 is provided through both ends in the length direction. When some particulate impurities fall into the slide groove 18, the mounting bracket 4 can push the particulate impurities down with the help of the scraper 20 during the sliding adjustment, thereby simultaneously removing the impurities in the slide groove 18.

[0029] like Figure 1 As shown, a support block 21 is detachably connected to the bottom of the mounting bracket 4. Multiple reserved holes of different heights are reserved on the mounting bracket 4. The support block 21 is fixed by connecting screws to the reserved holes. The support block 21 is used to abut against the bottom wall of the adjustment plate 5 to support it. The support block 21 supports the weight of the adjustment plate 5, thereby reducing the force at the connection of the connecting screw 12 and ensuring the stability of the installation of the adjustment plate 5.

[0030] like Figure 1 As shown, a support rod 22 is vertically installed on the top wall of the recessed platform 15. The support rod 22 is located directly below the screwing part 10. The bottom end of the support rod 22 is threaded to the surface of the recessed platform 15, and the top end of the support rod 22 is used to abut against the plane of the screwing part 10. The support rod 22 abuts against the screwing part 10 to limit the rotation of the screwing part 10. After the fixing bolt 6 is connected and fixed, the support rod 22 is rotated to move it upward and the top end abuts against the screwing part 10. In this way, the support rod 22 can limit the rotation of the fixing bolt 6, effectively preventing the fixing bolt 6 from rotating due to vibration. At the same time, the support rod 22 can also provide auxiliary support for the fixing bolt 6 and the entire mounting bracket 4, further improving the reliability of the support. The middle part of the support rod 22 is also provided with an integrated operating part 23. The operating part 23 is a regular hexagonal prism, which makes it easy to drive the rotation of the support rod 22 with a hexagonal wrench.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
