Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and more specifically, to a clamping mechanism for a copper wire tensile testing machine for new energy vehicles. Background Technology

[0002] In the new energy vehicle industry, copper wire is an important conductive material, and its quality directly affects the electrical performance of the vehicle. Tensile properties are one of the key indicators for measuring the quality of copper wire, so precise testing equipment is needed to detect it. However, existing copper wire tensile testing machines have many shortcomings when dealing with copper wires of different sizes used in new energy vehicles.

[0003] Traditional clamping devices are prone to damaging copper wires or failing to clamp them securely, causing the copper wires to slip during testing and making it impossible to obtain accurate test data. For thicker copper wires used in high-power motors, the clamping force may be insufficient, which also affects the accuracy of the test.

[0004] Therefore, we have made improvements to this and proposed a clamping mechanism for a copper wire tensile testing machine for new energy vehicles. Utility Model Content

[0005] The purpose of this invention is to address the issue that traditional clamping devices are prone to damaging copper wires or failing to clamp them securely, causing the copper wires to slip during testing and making it impossible to obtain accurate test data. Furthermore, for thicker copper wires used in high-power motors, the clamping force may be insufficient, which also affects the accuracy of the test.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A clamping mechanism for a copper wire tensile testing machine for new energy vehicles is proposed to improve the above-mentioned problems.

[0007] The application is as follows: It includes: a base plate with legs installed at the bottom; a placement plate fixedly installed on the top of the base plate; a stretching assembly for stretching copper wires is fixedly installed on the left side of the placement plate, a support frame is fixedly installed on the top of the stretching assembly, a housing is fixedly installed on the top of the support frame, and a clamping assembly for clamping and fixing copper wires is fixedly installed on one side of the housing.

[0008] To achieve the above technical solution, the clamping component design enables the clamping mechanism of the new energy vehicle copper wire tensile testing machine to adapt to copper wires of various sizes used in new energy vehicles. Whether it is ultra-micro copper wire or thick copper wire used in high-power motors, it can achieve stable clamping and effective tensile testing, thus broadening the application range of the testing machine. Using a tensile testing machine that can clamp copper wires of different sizes makes the equipment more versatile and adaptable to copper wires of different specifications, avoiding the need to replace testing equipment or make complex adjustments.

[0009] As a preferred embodiment of the clamping mechanism for the copper wire tensile testing machine for new energy vehicles provided by this utility model, the tensile assembly includes a first motor, which is fixedly installed on the left side of the placement plate. A bidirectional lead screw is fixedly installed at the output end of the first motor. Fixing blocks are threadedly connected to both sides of the surface of the bidirectional lead screw. A fixing plate is fixedly installed on the top of the fixing block. The top of the fixing plate is fixedly connected to the bottom of the support frame.

[0010] To achieve the above technical solution, when it is necessary to stretch the copper wire, both ends of the copper wire are placed inside the two housings, and the copper wire is clamped and fixed by the clamping assembly. By starting the first motor, the first motor drives the bidirectional lead screw to rotate. When the bidirectional lead screw rotates, it drives the two fixed blocks to move relative to or in opposite directions. When the two fixed blocks move in opposite directions, the copper wire clamped and fixed inside the housing is subjected to a stretch test.

[0011] In a preferred embodiment of the clamping mechanism for the copper wire tensile testing machine for new energy vehicles provided by this utility model, a limiting plate is sleeved on the surface of the first motor, and the side of the limiting plate near the placement plate is fixedly connected to the placement plate.

[0012] To achieve the above technical solution, the design of the limiting plate is used. One end of the limiting plate is fixedly connected to the first motor, and the other end is fixedly connected to the placement plate, making the first motor more stable during use.

[0013] In a preferred embodiment of the clamping mechanism for the copper wire tensile testing machine for new energy vehicles provided by this utility model, sliding blocks are fixedly installed on the front and rear sides of the bottom of the fixed plate, and sliding rods are slidably connected to the inner cavity of the sliding blocks. Both sides of the sliding rods are fixedly installed in the inner cavity of the placement plate.

[0014] To achieve the above technical solution, the design of sliding blocks and sliding rods allows the fixed plate to be limited during movement, preventing the fixed plate from shifting position during movement.

[0015] As a preferred embodiment of the clamping mechanism for the copper wire tensile testing machine for new energy vehicles provided by this utility model, the clamping assembly includes a second motor, which is fixedly installed on one side of the housing. A rotating gear is fixedly installed at the output end of the second motor. A gear ring meshes with one side of the rotating gear. A rotating ring is fixedly installed in the inner cavity of the gear ring. A first bevel gear is fixedly installed on one side of the rotating ring. A support ring is movably connected to one side of the first bevel gear. The support ring is fixedly connected to the housing on the side near the housing. Four second bevel gears mesh with the surface of the first bevel gear. A threaded rod is fixedly installed in the inner cavity of the second bevel gear. A threaded sleeve is threadedly connected to the surface of the threaded rod. Connecting plates are fixedly installed on both sides of the threaded sleeve. The connecting plates are slidably connected to the inner cavity of the support ring. An arc-shaped clamp is fixedly installed on one side of the connecting plate. The arc-shaped clamp is made of a soft material.

[0016] To achieve the above technical solution, when it is necessary to clamp and fix the copper wire, the copper wire is placed inside the housing, and the second motor is started. When the second motor is in use, it drives the rotating gear to rotate, which in turn drives the gear ring to rotate. The gear ring rotates through the rotating ring to drive the first bevel gear to rotate, which in turn drives the four second bevel gears to rotate. The second bevel gears rotate to drive the threaded rod to rotate, which in turn drives the threaded sleeve to move. The movement of the threaded sleeve drives the arc-shaped clamp to move through the connecting plate. The relative movement of the four arc-shaped clamps clamps and fixes the copper wire inside the housing, and can fix copper wires of different sizes.

[0017] In a preferred embodiment of the clamping mechanism for the copper wire tensile testing machine for new energy vehicles provided by this utility model, a stabilizing plate is sleeved on the surface of the second motor, and the side of the stabilizing plate near the outer shell is fixedly connected to the outer shell.

[0018] To achieve the above technical solution, the design of the stabilizing plate is used. One end of the stabilizing plate is fixedly connected to the second motor, and the other end is fixedly connected to the outer casing, making the second motor more stable during use.

[0019] In a preferred embodiment of the clamping mechanism for the copper wire tensile testing machine for new energy vehicles provided by this utility model, positioning blocks are fixedly installed on opposite sides of the two connecting plates, and positioning rods are slidably connected to the inner cavity of the positioning blocks. The side of the positioning rods near the support ring is fixedly connected to the support ring.

[0020] As a preferred embodiment of the clamping mechanism for the copper wire tensile testing machine for new energy vehicles provided by this utility model, two positioning plates are fixedly installed on the front and rear sides of the placement plate, and the side of the positioning plate closest to the bottom plate is fixedly connected to the bottom plate.

Using a tensile testing machine that can clamp copper wires of different sizes makes the equipment more versatile and adaptable to different specifications of copper wire, avoiding the need to replace testing equipment or make complex adjustments.
