[0026] Example 1

[0027] To address the technical problems in the background section, the following is provided: an electric actuator energization testing device.

[0028] Combination Figures 1-6 As shown, the present invention provides an electric actuator power-on testing device, including an operating table 1. The front of the operating table 1 is provided with a docking interface 12. A backing plate 4 is slidably installed inside the docking interface 12, and racks 41 are fixedly installed on both sides of the backing plate 4. A support plate 5 is fixedly installed at the bottom of the backing plate 4. An installation chamber 11 is provided at the top of the operating table 1. A drive assembly 2 is assembled inside the installation chamber 11. The drive end of the drive assembly 2 is connected to the racks 41 for transmission. A test assembly 3 is fixedly installed on the front of the backing plate 4.

[0029] During this process, personnel can perform power-on testing on the actuator after production on the operating table 1. Through the cooperation of the drive component 2, the back plate 4, and the support plate 5, the drive component 2 drives the rack 41, which can then be lifted within the interface 12. The purpose of lifting is to ensure that the load-bearing point of the device is lowered to the lowest point, making it more convenient and labor-saving for personnel to move heavier actuators up and down, thus increasing the work progress. The test component 3 enables built-in power-on testing. Personnel only need to connect and insert the power cord of the actuator, and internal isolation is provided during testing. Compared with the traditional tape connection, this is more stable and faster, and also reduces consumables.

[0030] The drive assembly 2 includes a motor 21 and a drive component 22. The drive component 22 is installed inside the mounting chamber 11, and the drive end of the drive component 22 is connected to the rack 41. The motor 21 is fixedly installed on one side of the operating table 1, and the output end of the motor 21 is connected to the drive component 22. The test assembly 3 includes a test cover 31, a lower connecting component 32, and an upper connecting component 33. The test cover 31 is fixedly installed on the front of the back plate 4. The lower connecting component 32 is installed inside the test cover 31, and the upper connecting component 33 is mated to the top of the lower connecting component 32.

[0031] Example 2

[0032] like Figure 1 and Figure 6 As shown, based on the above embodiments, this embodiment further provides the following:

[0033] In this embodiment, the drive component 22 includes a worm gear 221, a first drive shaft 222, a worm 223, a first bevel gear 224, a second drive shaft 225, a second bevel gear 226, and a ring gear 227. The second drive shaft 225 is installed inside the mounting chamber 11. The output end of the motor 21 is connected to the second drive shaft 225. The mounting chamber 11 is provided with a mounting port 13 communicating with the interface 12. The first drive shaft 222 is installed inside the mounting port 13, and one end of the first drive shaft 222 extends outwards. Inside the installation chamber 11, a ring gear 227 is fixedly installed on the first drive shaft 222, and the ring gear 227 meshes with the rack 41. A worm gear 221 is installed at the end of the first drive shaft 222. A worm 223 is installed at the bottom of the installation chamber 11, and the worm 223 meshes with the worm gear 221. A first bevel gear 224 is installed at the top of the worm 223. A second bevel gear 226 is fixedly installed on the second drive shaft 225, and the second bevel gear 226 meshes with the first bevel gear 224.

[0034] During this period, the motor 21 is started, and the output end of the motor 21 can drive the second transmission shaft 225 to rotate, at which time the second transmission shaft 225 will enter the transmission state;

[0035] The second drive shaft 225 drives the second bevel gear 226 to rotate, and the second bevel gear 226 then drives the worm gear 223 to rotate synchronously through the first bevel gear 224.

[0036] The worm gear 223 will drive the meshing worm wheel 221 to rotate in a different direction, and then the ring gear 227 on the first transmission shaft 222 will drive the rack 41, causing the back plate 4 to lift and lower within the interface 12, ensuring that personnel can move the heavier actuator up and down.

[0037] In this embodiment, a baffle 311 is movably installed on the front of the test housing 31, and a power socket 312 is fixedly installed on the front inside the test housing 31.

[0038] During this period, the baffle 311 is movably connected to the test housing 31 via a movable shaft. When the wire is connected, the connecting part will protrude. At that time, the structure will push the baffle 311, causing the baffle 311 to open outward. When the internal test is performed, the baffle 311 will automatically reset.

[0039] During testing, an electrical connection with the power socket 312 is required to power on the electric actuator.

[0040] In this embodiment, the test component 3 also includes a plug 34. The plug 34 is fixedly installed on the back of both the upper connecting component 33 and the lower connecting component 32. The plug 34 is electrically connected to the upper connecting component 33 and the lower connecting component 32. The positive and negative terminals of the plug 34 are assembled and connected to the lower connecting component 32.

[0041] The lower connecting component 32 has positive and negative terminals, each corresponding to a connecting plug 34. During this process, the operator connects the positive and negative wires on the actuator to the corresponding positive and negative terminals, thus connecting the plug 34 to the power socket 312 and achieving electrical connection.

[0042] Example 3

[0043] like Figures 1-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0044] In this embodiment, the lower connecting component 32 includes a carrier plate 321, an upper contact 322, a lower interface 323, a support rod 324, a handle 325, and a connecting block 326. The carrier plate 321 is slidably installed inside the test cover 31. Two sets of lower interfaces 323 are embedded in the top of the carrier plate 321. Support rods 324 are fixedly installed on both sides of the front of the carrier plate 321. A guide 313 is provided on one side of the test cover 31. A connecting block 326 extending from the guide 313 is fixedly installed on one side of the carrier plate 321. A handle 325 is fixedly installed on the outer end of the connecting block 326. The upper contact 322 is fixedly installed on both sides of the bottom of the upper connecting component 33, and the upper contact 322 and the lower interface 323 are connected to each other.

[0045] During this process, the person first pulls the handle 325, and the handle 325 transmits the power through the connecting block 326 to the guide port 313;

[0046] At that time, the carrier plate 321 can be extended outward, and personnel can connect the actuator wires to the lower interface 323 according to the positive and negative poles. After the connection is completed, the upper connecting component 33 is used to reset and press and fix the wires in the lower interface 323, so that the test state can be entered.

[0047] When the carrier plate 321 extends outward, the support rod 324 will use its own structural advantages to push the baffle 311 open, so that the operation can be carried out.

[0048] In this embodiment, the upper connecting component 33 includes a connecting rod 331, a cap 332, a spring 333, a mounting plate 334, a support base 335, and a pressure plate 336. The support base 335 is fixedly installed on the rear side of the top of the carrier plate 321, and the mounting plate 334 is fixedly installed on the front side of the support base 335. The pressure plate 336 is slidably installed on the handle 325 below the mounting plate 334. The connecting rod 331, which penetrates the mounting plate 334, is connected to the top of the pressure plate 336. The spring 333 is fitted on the connecting rod 331, and the cap 332 is connected to the top of the connecting rod 331. The upper contact 322 is assembled on both sides of the bottom of the pressure plate 336.

[0049] Based on the above, before and after the actuator's wire end is connected to the lower interface 323, personnel need to pull the cap 332.

[0050] Before the actuator wire is connected to the lower interface 323, the cap 332 lifts the pressure plate 336 via the connecting rod 331. At this time, the spring 333 enters the compressed state. After the actuator wire is connected to the lower interface 323, the cap 332 can be released. The upper contact 322 at the bottom of the pressure plate 336 will then press and fix the wire in the lower interface 323 to ensure that it can be used for testing.
