DETAILED DESCRIPTION
[0020] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.
[0021] A MGU motor wire breakage test mechanism includes a base 1 and an adjustable pressure block 2. The base 1 is provided with a fixed block 3. The adjustable pressure block 2 is used to compress the wire against the fixed block 3. The adjustable pressure block 2 includes a compression block 4 and a mounting block 5. The compression block 4 is detachably mounted on the mounting block 5 and protrudes from the outside of the mounting block 5. The fixed block 3 has curved surfaces at both ends. The fixed block 3 is detachably mounted on the base 1. The size, shape, and structure of the fixed block 3 are designed according to actual needs. In this embodiment, the fixed block 3 has a fixed structure with curved ends, which facilitates the winding of the wire around the fixed block 3. This embodiment simplifies the guide fixing method before the breakage test. The two ends of the wire are wrapped side by side around the corresponding fixed block 3 several times. This increases the contact area during the compression process, ensures balanced tension, and makes the test results more reliable. It also saves costs. Since the compression block 4 generally requires special processing, this structural design can significantly reduce the weight of the compression block 4.
[0022] The cross-section of the fixing block 3 is keyway-shaped, with both ends semicircular. The fixing block 3 is positioned with its flat surface facing upward and its curved side facing the compression block 4. This arrangement facilitates wire winding, and the curved surfaces at both ends ensure that the fixing block 3 does not interfere with the wire after it is led out of the compression surface, ensuring reliable compression and accurate testing.
[0023] In this embodiment, the base 1 comprises a base 6 and a mounting seat 7, forming an L-shaped overall structure. Specifically, the base 1 and mounting seat 7 are perpendicular plate-shaped structures. The fixed block 3 is mounted on the base 6, and the adjustable pressure block 2 is mounted on the mounting seat 7. The pressure surface of the pressure block 4 is arranged parallel to the side of the fixed block 3. In this embodiment, the bottom surface of the base 6 is a flat structure, and the side surface of the mounting seat 7 is also a flat structure.
[0024] In this embodiment, one side of the mounting block 5 is used to install the clamping block 4, and the other side is provided with a guide column 8 and a mounting column 9. A guide hole 10 is opened on the mounting seat 7 to cooperate with the guide column 8, and a connecting hole 11 is also provided to cooperate with the mounting column 9. The mounting column 9 and the connecting hole 11 are threaded; the mounting column 9 extends out of the outside of the mounting seat 7.
[0025] In order to ensure the stability of the pressing and the reliability of the process, there are two guide columns 8, which are located on both sides of the mounting column 9; a socket 12 is provided at the end of the mounting column 9, and an operating rod 13 is installed in the socket 12.
[0026] Specifically, the front side of the mounting block 5 is provided with a slot 14 having a dovetail cross-section, into which the compression block 4 is inserted. The compression block 4 includes a mounting portion 41 that fits into the slot 14 and a protruding portion 42. The width of the protruding portion is equal to the minimum width of the mounting portion 41. This structural design has the advantages of easy installation.
[0027] The tensile test mechanism is provided with two sets of bases 1 and fixed blocks 3 and adjustable pressure blocks 2 installed on the bases 1; the bases 1 are connected to the tension device through a connector, and the two sets of bases 1 are installed on the fixed blocks 3 and adjustable pressure blocks 2 on the base 1 to fix the two ends of the wire.
[0028] In this embodiment, a fixing threaded hole 15 is provided on the base 6, and a fixing threaded hole 2 16 is provided on the bottom of the fixing block 3. The fixing threaded hole 15 and the fixing threaded hole 2 16 are connected by fixing bolts. The number of the fixing hole 1 and the number of the fixing hole 2 are both two.
[0029] While working:
[0030] Install the two bases 1 on the tensioning equipment, then install the fixed block 3 and the adjustable pressure block 2 on the base 1. Adjust the distance between the pressure block 4 and the fixed block 3 before winding the wire. It is important to note that the wires need to be wound side by side during winding to increase the contact area between the wire and the pressure block 4. This ensures that the pressure block 4 can always compress the wire during tensioning, while preventing the phenomenon of a single wire being broken at the compression position due to uneven force, ensuring the safety of the test process. After the wire is wound, press the pressure block 4 against the wire; then gradually apply tension, and the tensile testing machine records the data in real time until the wire breaks; thus completing the test of the wire's breaking performance.
[0031] When it is necessary to match wires of different materials and structures, it is only necessary to replace the fixing block 3 and the pressing block 4 .
[0032] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
