[0001] This utility model belongs to the field of machine tool mechanical technology, specifically a torque amplification device for a disc motor used in a press. Background Technology

[0002] Disc motors inherently possess high power density, enabling them to generate significant torque and power within a relatively small volume. When equipped with a torque amplification device, the output torque can be further amplified to meet specific application requirements.

[0003] A utility model patent with publication number CN220418998U discloses an electric torque loading amplification device, comprising a loading box, a torque output shaft, a first reducer, a torque sensor, and a torque motor. The torque output shaft is supported in the loading box by bearings, and its tail end is connected to the output shaft of the first reducer. The input shaft of the first reducer is connected to the torque sensor via a coupling, and the torque sensor is also connected to the output shaft of the torque motor via a coupling. The housing of the first reducer is mounted on the loading box, which is mounted on a base. The housing of the torque motor is mounted on a bracket, which is mounted on the base.

[0004] In the process of implementing this application, the following problems were found with this technology: In the above patent documents, when amplifying the motor torque, the motor is mounted on an external bracket and the motor has a certain height; usually, the base of this type of motor is fixed to the bracket with bolts, and after long-term use, the bolts may become tightly connected to the components due to rust and corrosion, or become difficult to disassemble due to over-tightening, making it inconvenient to remove the motor for subsequent repair or maintenance.

[0005] Therefore, a torque amplification device for a disc motor used in a press is proposed. Utility Model Content

[0006] The purpose of this utility model is to improve the ease of disassembly and assembly of the disc motor body after the torque amplification operation is completed, so as to facilitate maintenance and upkeep. This application provides a torque amplification device for a disc motor used in presses.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A disc motor torque amplification device for a press includes a base plate, a disc motor mechanism, a torque amplification mechanism, a press body, a positioning seat, and a connecting mechanism. The positioning seat is installed on the upper left surface of the base plate, the torque amplification mechanism is installed on the upper right surface of the base plate, the disc motor mechanism is disposed on the upper surface of the positioning seat, and the press body is disposed on the right side of the torque amplification mechanism and the base plate.

[0009] The disc motor mechanism includes a disc motor body, a motor output shaft is mounted on the right side of the disc motor body, and the end of the motor output shaft away from the disc motor body is connected to the torque amplification mechanism. A base is fixedly connected to the lower surface of the disc motor body, and an insert block is fixedly connected to the lower surface of the base. Positioning holes are provided on both sides of the insert block.

[0010] The upper surface of the positioning seat is provided with a slot, the inner surface of the slot is inserted into the outer surface of the positioning hole, the opposite inner sidewall of the slot is provided with a side hole, and the inner sidewall of the side hole is provided with a through hole.

[0011] The number of connecting mechanisms is two. Each connecting mechanism includes a spring, which is fixedly connected to the inner wall of the side hole near the through hole. A pin is fixedly connected to the end of the spring away from the through hole. The outer surface of the pin is slidably connected to the inner wall of the side hole. The end of the pin away from the spring is inserted into the positioning hole. A pull rod is fixedly connected to the middle of the side of the pin near the spring. The end of the pull rod away from the pin passes through the center of the spring and the through hole and extends to the outside, where a pulling block is fixedly connected.

[0012] Furthermore, the torque amplification mechanism includes a loading box and a reducer. The loading box is fixedly connected to the upper surface of the base plate, and the housing of the reducer is mounted on the loading box.

[0013] Furthermore, the torque output shaft is supported in the loading box by bearings, and the tail end of the torque output shaft is connected to the output shaft of the reducer. The input shaft of the reducer is connected to the torque sensor through a coupling, and the end of the torque sensor away from the reducer is connected to the output shaft of the motor through a coupling.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] In this invention, when the disc motor body needs to be disassembled for repair or maintenance, the pull block can be pulled to cause the pull rod to drive the insertion post to compress the spring, so that the insertion post is pulled into the side hole. Then, the motor output shaft and torque amplification mechanism can be separated. At this time, the disc motor body can be pulled upward to separate the insertion block from the slot, so that the disc motor body can be quickly removed for repair and maintenance. When the disc motor body needs to be reassembled on the positioning seat, the insertion block can be inserted into the slot and the positioning hole can be aligned with the side hole. Then, the pull block can be released so that the spring can drive the insertion post to be inserted into the positioning hole under the elastic reset action, realizing the quick connection between the disc motor mechanism and the positioning seat. Through the cooperation of the above structures, the disassembly and assembly of the disc motor body can be improved after the torque amplification work is completed, so as to facilitate maintenance and upkeep.

The tail end of shaft 34 is connected to the output shaft of reducer 32. The input shaft of reducer 32 is connected to torque sensor 33 via a coupling. The end of torque sensor 33 away from reducer 32 is connected to motor output shaft 22 via a coupling. The end of torque output shaft 34 away from loading box 31 is connected to the main drive shaft of press body 4. Specifically, when using this device, disc motor body 21 is first connected to an external power source. When disc motor body 21 applies torque 1:1 to the input shaft of torque sensor 33 via motor output shaft 22, the output shaft of torque sensor 33 applies torque 1:1 to the input shaft of reducer 32. The output shaft of reducer 32 amplifies the torque by a multiple of the reduction ratio and applies it to the tail end of torque output shaft 34. The head of torque output shaft 34 applies torque 1:1 to the main drive shaft of press body 4, thereby amplifying the torque of the main drive shaft of press body 4.

[0025] Reference Figures 1-3The input end of the disc motor body 21 is electrically connected to an external power supply. A base 23 is fixedly connected to the lower surface of the disc motor body 21, and a plug 24 is fixedly connected to the lower surface of the base 23. Positioning holes 25 are provided on both sides of the plug 24. A slot 51 is provided on the upper surface of the positioning seat 5. The inner surface of the slot 51 is inserted into the outer surface of the positioning hole 25. A side hole 52 is provided on the opposite inner side wall of the slot 51, and a through hole 53 is provided on the inner side wall of the side hole 52. There are two connecting mechanisms 6, each including a spring 61. A spring 61 is fixedly connected to the inner wall of the side hole 52 near the through hole 53. A post 62 is fixedly connected to the end of the spring 61 away from the through hole 53. The outer surface of the post 62 is slidably connected to the inner wall of the side hole 52. The end of the post 62 away from the spring 61 is inserted into the positioning hole 25. A pull rod 63 is fixedly connected to the middle of the side of the post 62 near the spring 61. The end of the pull rod 63 away from the post 62 extends through the center of the spring 61 and the through hole 53 to the outside and is fixedly connected to a pulling block 64. The length of the post 62 is greater than the depth of the positioning hole 25. Specifically, in... During long-term use, to ensure stable operation and extend the service life of the motor, necessary maintenance of the disc motor body 21 is essential. When disassembling or maintaining the disc motor body 21, the pull block 64 can be pulled to cause the pull rod 63 to drive the insert 62 to compress the spring 61, thereby pulling the insert 62 into the side hole 52. Then, the motor output shaft 22 can be separated from the torque amplification mechanism 3. At this time, pulling the disc motor body 21 upwards will separate the insert 24 from the slot 51, allowing the disc motor body 21 to be quickly disassembled. Quickly remove for maintenance; when it is necessary to reassemble the disc motor body 21 onto the positioning seat 5, the insert block 24 can be inserted into the slot 51 and the positioning hole 25 can be aligned with the side hole 52. Then the pull block 64 can be released so that the spring 61 can drive the insert post 62 to be inserted into the positioning hole 25 under the elastic reset action, realizing the quick connection between the disc motor mechanism 2 and the positioning seat 5. Through the cooperation of the above structure, the disassembly and assembly of the disc motor body 21 can be improved after the torque amplification work is completed, so as to carry out maintenance.

[0026] The implementation principle of an embodiment of the disc motor torque amplification device for a press in this application is as follows:

[0027] When using this device, first connect the disc motor body 21 to an external power source. After the disc motor body 21 applies torque 1:1 to the input shaft of the torque sensor 33 through the motor output shaft 22, the output shaft of the torque sensor 33 will apply torque 1:1 to the input shaft of the reducer 32. The output shaft of the reducer 32 will amplify the torque by a multiple of the reduction ratio and apply it to the tail of the torque output shaft 34. The head of the torque output shaft 34 will apply torque 1:1 to the main drive shaft of the press body 4, thereby realizing the torque amplification of the main drive shaft of the press body 4.

[0028] During long-term use, to ensure stable operation and extend the service life of the motor, necessary maintenance of the disc motor body 21 is essential. When disassembling or maintaining the disc motor body 21, the pull block 64 can be pulled to cause the pull rod 63 to drive the insert 62 to compress the spring 61, thereby pulling the insert 62 into the side hole 52. Then, the motor output shaft 22 can be separated from the torque amplification mechanism 3. At this time, pulling the disc motor body 21 upwards will separate the insert 24 from the slot 51, allowing the disc motor body 21 to be quickly disassembled. Quickly remove for maintenance; when it is necessary to reassemble the disc motor body 21 onto the positioning seat 5, the insert block 24 can be inserted into the slot 51 and the positioning hole 25 can be aligned with the side hole 52. Then the pull block 64 can be released so that the spring 61 can drive the insert post 62 to be inserted into the positioning hole 25 under the elastic reset action, realizing the quick connection between the disc motor mechanism 2 and the positioning seat 5. Through the cooperation of the above structure, the disassembly and assembly of the disc motor body 21 can be improved after the torque amplification work is completed, so as to carry out maintenance.
