Description

Technical Field

[0001] The invention relates to the technical field of flat wire motor stator production, and in particular to a twist head tooth guard quick-change mechanism. Background Art

[0002] Flat wire motors are usually composed of stators, rotors, reducers, etc., and the stator of a flat wire motor is one of the core components of a flat wire motor. The stator is the stationary part of the motor, usually composed of a coil wound with copper wire, and is fixed in the motor housing. Its main function is to generate a magnetic field, drive the rotor to rotate, and complete the operation of the motor.

[0003] The main function of the flat wire motor stator is to generate a magnetic field, which can be a constant DC magnetic field or a variable AC magnetic field. When the current passing through the stator coil changes, the magnetic flux in the conductor will change, which will affect the shape of the magnetic field, and the shape of the magnetic field determines the direction and speed of rotation of the rotor. The magnetic field generated in the stator interacts with the magnetic field in the rotor, causing the rotor to rotate under the action of torque.

[0004] During the production and processing of flat wire motor stators, the existing twist head tooth guards are installed and disassembled by manual forklifts. The replacement time is about 30 minutes and requires 2 or more people to operate the replacement. The upper and lower tooth guards are heavy, about 60 to 80 kg, which is inconvenient to carry during replacement and poses a safety risk. At the same time, the installation of the tooth guards needs to be aligned, which requires a high level of technical skills from the installers. The positioning and concentricity of the tooth guards depend on the accuracy of the driving mechanism of the equipment, and the interchangeability is poor.

[0005] The new energy flat wire stators are updated faster and the cost control is getting lower and lower. Usually one production line can be compatible with multiple products at the same time. The changeover time requirements are getting shorter and shorter. The traditional manual disassembly and changeover can no longer meet the latest needs of customers. Summary of the invention

[0006] In order to solve the above technical problems, the present invention proposes a twist head mouthguard quick change mechanism, which is positioned by the upper and lower mouthguards, and the upper and lower mouthguards are changed as a whole when changing the type, and the upper and lower mouthguards can be changed together. The operation is simple and the adaptability is strong. The technical solution of the present invention is implemented as follows:

[0007] A twist-head mouthguard quick-change mechanism comprises an upper mouthguard, a lower mouthguard and an automatic transport mechanism; the upper surface of the lower mouthguard is provided with a first positioning member and a second positioning member;

[0046] The embodiments of the present invention will be described in more detail below by way of examples. It should be noted that the embodiments of the present invention are not limited to these examples.

[0047] In a specific embodiment, Figures 1 to 7 As shown, a twist-head mouthguard quick-change mechanism comprises an upper mouthguard 1, a lower mouthguard 2 and an automatic transport mechanism 3; the upper surface of the lower mouthguard 2 is provided with a first positioning member 4 and a second positioning member 5.

[0048] The lower surface of the upper mouthpiece 1 is provided with a first positioning hole matched with the first positioning member 4 and a second positioning hole matched with the second positioning member 5 .

[0049] A first driving rod 7 is arranged on the outer edge of the lower mouthpiece 1 .

[0050] A second driving rod 8 is arranged on the outer edge of the upper mouthpiece 2 .

[0051] The first driving rod 7 and the second driving rod 8 are both provided with through holes for the third positioning member 6 to be inserted into.

[0052] The automatic transport mechanism 3 is provided with a swing claw 9 for grabbing the lower mouthguard 2 and a first locking mechanism 10 for fixing the upper mouthguard 1 .

[0053] The lower surface of the lower mouthpiece 2 is provided with a groove 17 for the swing claw 9 to be inserted into.

[0054] In this embodiment, the first positioning member 4 and the second positioning member 5 have different shapes.

[0055] Specifically, the first positioning member 4 is a prismatic pin, and the second positioning member 5 is a cylindrical pin.

[0056] In this embodiment, a quick-change auxiliary component 11 is also provided.

[0057] The quick-change auxiliary assembly 11 includes at least one mouthguard placement plate 12 .

[0058] The mouthguard placement plate 12 is provided with a first receiving member 13 , a second receiving member 14 and a third receiving member 15 .

[0059] The lower surface of the lower mouthpiece 2 is provided with a third positioning hole matched with the first receiving member 13 and a fourth positioning hole matched with the second receiving member 14 .

[0060] The third receiving member 15 is used to be inserted into the round hole 18 of the first driving rod 7 and the second driving rod 8.

[0061] In this embodiment, the first receiving member 13 and the first positioning member 4 have the same structure.

[0062] The second receiving member 14 has the same structure as the second positioning member 5 .

[0063] In this embodiment, the upper mouthguard 1 is an I-shaped structure.

[0064] This embodiment further includes a second locking mechanism 16 .

[0065] The second locking mechanism 16 is arranged along the circumference of the installation station of the lower mouthpiece 2;

[0066] The second locking mechanism 16 is used to fix the lower mouthpiece 2 .

[0067] In this embodiment, since the structures of the first positioning member 4 and the second positioning member 5 are different, there will be no wrong insertion when the upper mouthguard 1 and the lower mouthguard 2 are combined. In order to further ensure the stability and accuracy of transportation, this embodiment uses the third positioning member 6 to be inserted into the first driving rod 7 and the second driving rod 8, and the three-point positioning is more accurate.

[0068] In this embodiment, the upper and lower mouthguards 1 and 2 are transported as a whole by the automatic transport mechanism 3, and the swing claw 9 is inserted into the groove 17 in the lower mouthguard 2 to grab the whole. In this way, when transporting and replacing, the upper and lower mouthguards 1 and 2 are transported as a whole, and there is no need for centering correction, so the installation accuracy is higher and the operation is simpler.

[0069] In this embodiment, the first locking mechanism 10 and the second locking mechanism 16 have the same structure.

[0070] In this embodiment, multiple mouthguard placement trays 12 can be provided, and users can select multiple different mouthguard placement trays 12 according to their needs, and the specifications of the mouthguards on each mouthguard placement tray 12 can also be selected according to their needs, so as to better meet the needs of quick replacement of mouthguards for a production line compatible with multiple specifications of products. Each mouthguard placement tray 12 corresponds to a transport line, and the corresponding transport line is started when replacement is required.

[0071] In order to ensure the accuracy and safety of the movement and installation of the mouthguard, the present embodiment locks the upper mouthguard 1 through multiple first locking mechanisms 10, and grasps the lower mouthguard 2 through multiple swing claws 9, to ensure that the upper mouthguard 1 or the lower mouthguard 2 will not shift or fall off during transportation or installation, thereby avoiding affecting the production line or causing accidents.

[0072] The specific use process of this embodiment is as follows:

[0073] Install:

[0074] First, the transport line delivers the upper and lower mouthguards 1 and 2 to be installed to the grabbing station.

[0075] The automatic transport mechanism 3 moves above the entire upper mouthpiece 1 and the lower mouthpiece 2 .

[0076] The automatic transport mechanism 3 falls, the swing claw 9 extends and is stuck in the groove 17 on the lower surface of the lower mouthguard 2. At the same time, the first locking mechanism 10 extends inward and is stuck in the waist of the upper mouthguard 1 of the I-shaped structure.

[0077] After the fixation is completed, the automatic transport mechanism 3 is lifted up to transport the upper mouthguard 1 and the lower mouthguard 2 as a whole to the installation station of the lower mouthguard 2. After being transported to the location, the second axial locking mechanism 16 of the installation station extends inward and is stuck in the center of the lower mouthguard 2 of the I-shaped structure.

[0078] After the lower mouthguard 2 is fixed, the swing claw 9 is released, the automatic transport mechanism 3 is lifted, the upper mouthguard 1 is separated from the lower mouthguard 2, and the upper mouthguard 1 is lifted to the upper mouthguard fixing station.

[0079] The upper mouthguard 1 and the lower mouthguard 2 are installed.

[0080] Disassembly:

[0081] The automatic transport mechanism 3 falls;

[0082] The first positioning hole and the second positioning hole on the lower surface of the upper mouthguard 1 are respectively engaged with the first positioning piece 4 and the second positioning piece 5 on the upper surface of the lower mouthguard 2. At the same time, the third positioning piece 6 on the first driving rod 7 extending from the upper mouthguard 1 falls into the through hole on the second driving rod 8 extending from the lower mouthguard 2.

[0083] The second locking mechanism 16 in the circumferential direction of the lower mouthpiece installation station retreats outwards, and the swing claw 9 on the lower surface of the automatic transport mechanism 3 extends out and is stuck in the groove 17 on the lower surface of the lower mouthpiece 2.

[0084] The automatic transport mechanism 3 is lifted up, and the upper mouthguard 1 and the lower mouthguard 2 are placed as a whole on the transport line.

[0085] Disassembly complete.

[0086] The process of replacing the mouthguard is similar to that of installing it, and will not be described in detail in this embodiment.

[0087] Through the above process, the present embodiment realizes the automated overall transportation and disassembly of the upper mouthguard 1 and the lower mouthguard 2, with a simple structure and precise positioning.

[0088] It should be pointed out that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
