[0028] A control unit 2 is provided on the machine base 1, and the control unit 2 specifically controls the operation of the entire power cord bending device. A clamping and swinging component is provided in the machine base 1, such as Figure 2 As shown, the machine base 1 includes a fixed base plate 11 , and each machine base 1 is provided with three groups of clamping and swinging assemblies, which are all arranged on the fixed base plate 11 .

[0029] Each clamping and swinging assembly includes a turntable 31 mounted on a fixed baseplate 11, a transmission assembly for controlling the rotation of the turntable 31 relative to the fixed baseplate 11, and a fixture assembly mounted on the turntable 31 for mounting a power cord. The transmission assembly includes a rotating shaft 321, a servo motor 322 for controlling the rotation of the rotating shaft 321 relative to the fixed baseplate 11, and a speed reducer 323. The rotating shaft 321 is connected to the turntable 31. The axis of the rotating shaft 321 extends in the front-to-back direction, while the fixed baseplate 11 extends horizontally.

[0030] Each clamp assembly consists of a base 331 mounted on the turntable and two adapter fixtures 332 detachably mounted relative to the base 331. The base 331 extends horizontally. A screw slide assembly 333 is also mounted on the turntable 31. The base 331 is connected to the turntable 31 via the screw slide assembly 333, allowing the base 331 to be moved vertically relative to the turntable 31.

[0031] A card hole 3311 is provided on the female base 331, and a card seat 3321 that cooperates with the card hole 3311 is provided on the adapter tooling 332. The card seat 3321 can be carded at multiple angles in the horizontal direction relative to the card hole 3311, that is, the card seat 3321 can be set in the card hole 3311 at multiple angles around the axis extending in the up and down directions. Specifically, in one embodiment, the cross-sections of the card hole 3311 and the card seat 3321 are both circular. In other embodiments, the cross-sections of the card hole 3311 and the card seat 3321 can also be square. By setting the card seat 3321 to be carded at multiple angles with the card hole 3311, the bending scenarios of the power cord are made more diverse.

[0032] The adapter tool 332 has a card interface 3328 , and the size of the card interface 3328 is adjustable so that it can adapt to multiple sub-sockets 334 or multiple power cords 5 , and then test multiple power cords 5 .

[0033] Specifically, in one embodiment, Figure 3As shown, the adapter tool 332 includes a base 3321 set at the bottom, an inverted U-shaped fixed frame 3322 fixed relative to the base 3321, a pressing piece 3323, an adjusting knob 3324, a first threaded rod 3325, a sliding rod 3326 and an upper base 3327 set between the adjusting knob 3324 and the fixed frame 3322, a card interface 3328 is formed between the pressing piece 3323 and the base 3321, the pressing piece 3323 can be moved up and down relative to the base 3321, thereby adjusting the height of the card interface 3328, and the two ends of the first threaded rod 3325 are respectively connected to the upper base 3327 and the pressing piece 3323 is rotatably connected, the top end of the first threaded rod 3325 is fixedly connected to the adjusting knob 3324, and the first threaded rod 3325 is arranged to rotate relative to the fixed frame 3322 and slide up and down. There are two sliding rods 3326, and the two ends of each sliding rod 3326 are respectively fixedly connected to the upper seat 3327 and the pressing piece 3323. An elastic member (not shown in the figure) can also be set between the upper seat 3327 and the fixed frame 3322. For example, an elastic member is sleeved on this area of ​​the sliding rod 3326. When the adjusting knob 3324 is turned, the upper seat 3327 moves downward relative to the fixed frame 3322, and the elastic member is compressed. This adapter tool 332 needs to be adapted to a detachable sub-base 334, which is used to insert the plug of the power cord 5. The sub-base 334 is provided with a plug interface 3341 for plugging the power cord 5 and a fixing hole that passes through the plug interface 3341. The fixing hole is screwed with a screw 3342 for fixing the plug of the power cord 5. Figure 5-7 As shown, there are three different sub-seats 334, Figure 5 The sub-base 334 is suitable for a 3-hole plug, and the plug interface 3341 is set on the front of the sub-base 334. Figure 6 The sub-base 334 is suitable for a 2-hole plug, and the plug interface 3341 is set on the bottom surface of the sub-base 334. Figure 7 The sub-base 334 is suitable for a 3-hole plug, and the plug interface 3341 is set on the front of the sub-base.

[0034] Specifically, in one embodiment, Figure 4 As shown, the adapter tool 332 includes a base 3321 disposed at the bottom, a side base 3331 fixed relative to the base 3321, a second threaded rod 3332 rotatably disposed relative to the side base 3331, and a first piece 3333 and a second piece 3334 that can be relatively moved closer and further apart in the left and right directions. The second threaded rod 3332 includes a forward thread (not shown) that cooperates with the first piece 3333 and a reverse thread (not shown) that cooperates with the second piece 3334. A card interface is formed between the first piece 3333 and the second piece 3334. By twisting the second threaded rod 3332, the width of the card interface 3328 in the left and right directions can be adjusted. This adapter tool 332 can directly connect to the power cord 5 without the need for a sub-base 334.

[0035] When using the power cord bending device of the present invention, the power cord is turned on through the control unit 2. The appropriate sub-holder 334 is selected according to the power cord 5 to be tested, and the power cord 5 is then inserted into the sub-holder 334. The power cord 5 is tightened with screws, and the sub-holder 334 is snapped into the card interface 3328 of the adapter tool 332. The card holder 3321 of the adapter tool 332 is snapped into the card hole 3311. Then, a counterweight 4 is set for the power cord 5. The current, voltage, and swing angle are set through the control unit 2, and the test is started. If the power cord 5 does not need to be adapted to the sub-holder 334, the power cord 5 is directly snapped into the card interface 3328 of the adapter tool 332.

[0036] The utility model provides a power cord bending device that allows 6 power cords to be bent at the same time by setting 3 groups of clamping and swinging components. The power cord can be connected to the test current and test voltage during the test. The test current is adjustable from 0 to 30A, the test voltage is adjustable from 0 to 300V AC, and the 50-60Hz is adjustable. By setting the rotating shaft, the turntable rotation angle is adjustable from 0 to 180 degrees, and the turntable rotation direction can also be adjusted. Specifically, the turntable can swing back and forth or 360 degrees, and the swing speed can be 0 to 120 circles / minute. Figure 2 As shown, a counterweight 4 can be provided on the power line to increase the load.
