Detailed Description of the Embodiment
[0015] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings.
[0016] As Figure 1 and Figure 2 shown, the high-voltage withstand test device for an electric push rod provided by the embodiment of the present application has a structure including a frame 1, and further includes at least one fixture 2 provided on the frame 1, at least one sliding carrier mechanism 3 arranged along the X direction on the frame 1 corresponding to the fixture 2 one by one, and a withstand voltage tester 4 fixedly arranged on the frame 1. An imitation groove for carrying the motor end of the electric push rod is provided on the fixture 2. The sliding carrier mechanism 3 includes a carrier 31, a fixing block 32 fixedly arranged on the frame 1 corresponding to the side of the fixture 2, two guide posts 33 with both ends connected to the fixture 2 and the fixing block 32 respectively, and two linear bearings 34 sleeved on the two guide posts 33 respectively. Both sides of the carrier 31 are fixedly connected to the two linear bearings 34 respectively.
[0017] In actual use, place the motor end of the electric push rod on the profiling groove, place the push rod end of the electric push rod on the carrier 31, ground the ground wire of the withstand voltage tester 4, make the test wire of the withstand voltage tester 4 contact the outer shell of the electric push rod, and supply power to the electric push rod through an external power supply. After the electric push rod is powered on, the push rod of the electric push rod extends towards the fixed block 32, pushing the carrier 31 to move towards the fixed block 32, so that the carrier 31 drives the linear bearing 34 to slide synchronously along the guide post 33.
[0018] In the above design, the sliding carrier mechanism 3 carriers the push rod of the electric push rod, which can effectively ensure that the electric push rod undergoes a withstand voltage test in a working state, ensure that the withstand voltage test more conforms to the actual use conditions of the electric push rod, and can ensure the smoothness during the movement of the push rod.
[0019] Specifically: as Figure 2 shown, the carrier 31 includes a first plate 311 fixedly connected to two linear bearings 34 on both sides respectively, a first vertical plate 312 arranged on the side of the first plate 311 close to the fixture 2, and a second vertical plate 313 arranged on the side of the first plate 311 close to the fixed block 32. The first vertical plate 312 is provided with a carrier groove for carrying the push rod of the electric push rod, and the side of the second vertical plate 313 opposite to the fixture 2 is used to abut against the push rod end of the driving push rod.
[0020] In actual use, the push rod is carried on the carrier groove. After the electric push rod is powered on, the push rod extends and abuts against the second vertical plate 313. During the continuous extension of the push rod, a thrust is applied to the second vertical plate 313, so that the entire carrier 31 moves towards the fixed block 32.
[0021] In the above design, the structural design and specific implementation method of the carrier 31 facilitate the stable carrying of the push rod.
[0022] Specifically: as Figure 1 shown, the sliding carrier mechanism 3 further includes a sheet metal cover 35 fixedly connected to the fixture 2 and the fixed block 32 at both ends. The sheet metal cover 35 includes a top plate, a first side plate arranged on one side of the top plate, and a second side plate arranged on the other side of the top plate. The top plate, the first side plate, and the second side plate are integrally formed, and the top plate, the first side plate, and the second side plate form a receiving groove for receiving the linear bearing 34.
[0023] In actual use, the linear bearing 34 is shielded by the sheet metal cover 35 to prevent the linear bearing 34 from being externally interfered during the sliding process.
[0024] In the above design, the structural design and specific implementation method of the sheet metal cover 35 can effectively protect the linear bearing 34.
[0025] Specifically, an anti-static rubber sheet is provided on the upper end surface of the frame 1.
[0026] In the above design, the design of the anti-static rubber sheet can ensure that the frame 1 is effectively anti-static.
[0027] Specifically: as Figure 2 shown, the fixing block 32 includes a bottom plate 321 fixedly connected to the upper end surface of the frame 1 and a vertical plate 322 provided on one side of the bottom plate 321, and the guide post 33 is fixedly connected to the vertical plate 322.
[0028] During actual use, the vertical plate 322 and the guide post 33 are fixedly connected to realize the fixation of the guide post 33.
[0029] In the above design, the structural design and implementation manner of the fixing block 32 can effectively realize the fixation of the guide post 33.
