Description

Technical Field

[0001] The utility model relates to the technical field of anti-wear detection devices, in particular to an anti-wear detection device for electric hardware. Background Art

[0002] Wear testing devices are used to evaluate the ability of a material or component to resist wear under specific conditions. These devices typically simulate wear conditions found in actual working environments, such as friction, pressure, and temperature, to measure the wear rate, wear volume, or other relevant parameters of the material or component.

[0003] Common electrical hardware wear resistance testing devices generally clamp the electrical hardware and then use a grinding wheel to grind the surface of the electrical hardware to test the wear resistance of the electrical hardware. However, since the environment in which the electrical hardware is used is affected by wind and equipment operation, vibration or swing will occur. The grinding wheel can only test the wear resistance of the electrical hardware in a static manner and cannot simulate the dynamic wear resistance of the electrical hardware, resulting in inaccurate wear resistance testing of the electrical hardware. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides an anti-wear detection device for electrical hardware to solve the problem proposed in the above background technology that the anti-wear detection of electrical hardware can only be performed in a static manner through a grinding wheel, and the anti-wear performance of the electrical hardware in a dynamic state cannot be simulated, resulting in inaccurate anti-wear detection of the electrical hardware.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-wear detection device for electrical hardware, comprising:

[0006] An installation box, wherein a working box is installed on the upper surface of the bottom plate of the installation box;

[0007] A motor is provided on the lower surface of the top plate of the working box, wherein the rotor of the motor is coaxially mounted with a rotating rod, and eccentric wheels are evenly mounted on the surface of the rotating rod;

[0008] A lifting plate is arranged above the eccentric wheel, and lifting rods are evenly installed on the upper surface of the lifting plate. The top ends of the lifting rods pass through the top plate of the working box and are installed with mounting platforms;

[0009] The stepper motor is arranged on the lower surface of the top plate of the installation box. The rotor of the stepper motor is coaxially mounted with a screw rod. The surface of the screw rod is screwed with an adjusting rod. The bottom end of the adjusting rod is mounted with a driving machine. The rotor of the driving machine is coaxially mounted with a grinding wheel.

[0010] Preferably, sliders are installed on both sides of the adjusting rod, and slide rails are welded on both sides of the lower surface of the top plate of the installation box. The sliders are inserted into the inner cavity of the slide rails. The sliders cooperate with the slide rails to limit the adjusting rod so that the adjusting rod can move vertically.

[0011] Preferably, limit blocks are installed on both sides of the lifting plate, and limit grooves are provided on both sides of the inner walls of the working box. The limit blocks are inserted into the inner cavity of the limit grooves. The limit blocks and the limit grooves enable the lifting plate to be lifted and lowered stably.

[0012] Preferably, the outer circumference of the lifting rod is sleeved with a return spring, the bottom end of the return spring is installed on the upper surface of the lifting plate, and the top end of the return spring is connected to the top plate of the working box. The return spring is used to reset the lifting plate so that the lifting plate can perform reciprocating lifting and lowering motion.

[0013] Preferably, threaded rods are screwed onto both sides of the mounting platform, and positioning plates are mounted on the inner ends of the threaded rods via bearings. Rotating the threaded rods can drive the positioning plates to move, thereby clamping the electrical fittings.

[0014] Preferably, movable blocks are installed on both sides of the bottom of the positioning plate, and movable grooves are opened on the upper surface of the mounting platform at positions corresponding to the movable blocks. The movable blocks are embedded in the inner cavity of the movable grooves. The movable blocks and the movable grooves enable the positioning plate to clamp the electrical hardware more firmly.

[0015] Compared with the prior art, the present invention provides an anti-wear detection device for electrical hardware, which has the following beneficial effects:

[0016] The anti-wear detection device for electric hardware is equipped with a stepper motor that can drive the screw to rotate, thereby driving the adjusting rod to move up and down, and further driving the grinding wheel to contact the surface of the electric hardware. The starting motor can drive the rotating rod to rotate, thereby driving the eccentric wheel to rotate. When the eccentric wheel rotates, it can drive the lifting plate to move up and down, thereby driving the mounting table to move up and down, so that the electric hardware can continuously and dynamically contact the surface of the grinding wheel, can simulate the dynamic anti-wear performance of the electric hardware, and improve the accuracy of anti-wear detection of the electric hardware.
