Detailed Implementation

[0014] The present invention will now be further described with reference to the accompanying drawings.

[0015] like Figures 1 to 8 As shown, an insulation withstand voltage testing machine includes a testing instrument 8, a conveyor 1, a fixing device 4, a positioning device 2, a lifting device 5, and a plug-in device 6. The fixing device 4 is movably mounted on the conveyor 1 and is used to fix the compressor 9, ensuring its position remains unchanged during testing and facilitating the insertion of the test socket 67 into the wiring plug 92 of the compressor 9. The positioning device 2 is installed inside the conveyor 1 and is used to position the fixing device 4 so that the compressor 9 and the plug-in device 6 are positioned opposite each other. The lifting device 5 is installed inside the conveyor 1 and located at the positioning device 2, used to lift the fixing device 4 so that it is detached from the conveyor 1 and the compressor 9 plug is coaxially aligned with the plug-in device 6. The plug-in device 6 is located on one side of the conveyor 1 and is connected to the testing instrument 8 and opposite to the fixing device 4 lifted by the lifting device 5, used to electrically connect the testing instrument 8 and the compressor 9. The positioning device 2, lifting device 5, and plug-in device 6 are arranged in a one-to-one correspondence, and there are at least two of each; the specific number can be set according to actual testing requirements.

[0016] Multiple electrical safety tests can be performed simultaneously on a single conveyor 1, which greatly shortens the overall testing time and reduces the number of conveyors 1, thus reducing the floor space required.

[0017] The fixing device 4 includes a fixing base plate 41, positioning posts 42, and support posts 43. The fixing base plate 41 is a rectangular plate with four lifting positioning holes 411 arranged in an array. There are two positioning posts 42, which are installed on the fixing base plate 41 and are positioned opposite to the mounting holes 91 on both sides of the compressor 9. The positioning posts 42 are stepped posts and match the mounting holes 91 for insertion into the mounting holes 91 to position the compressor 9. The support posts 43 are fixed on the fixing base plate 41 and are positioned opposite to the bottom of the compressor 9. The support posts 43 are used to abut against the bottom of the compressor 9, and there are four of them to form a stable support. Together with the positioning posts 42, they can keep the position of the compressor 9 unchanged when the insertion device 6 is inserted into the compressor 9, and facilitate the installation and removal of the compressor 9.

[0018] In order to place the fixed base plate 41 on the conveyor 1, several sliding cams 44 are provided around the fixed base plate 41. The sliding cams 44 protrude from the perimeter of the fixed base plate 41 and slide against the conveyor 1. The sliding cams 44 can also reduce the contact area with the conveyor 1, thereby reducing the friction and making the movement of the fixed base plate 41 on the conveyor 1 smoother.

[0019] The positioning device 2 includes a positioning seat 22 and a blocking cylinder 21. The positioning seat 22 is mounted on the conveyor 1 and connected to the blocking cylinder 21. The blocking cylinder 21 is positioned opposite to the fixed base plate 41, so that the fixed base plate 41 stops moving on the conveyor 1 and is positioned opposite to the lifting device 5 below. The blocking cylinder 21 is a commercially available and mature product, and will not be described in detail here. The lifting device 5 includes a lifting base plate 51, lifting guide rods 52, lifting cylinders 53, lifting plates 54, and lifting pins 55. The lifting base plate 51 is fixed to the conveyor 1 and connected to the lifting cylinder 53. The lifting guide rods 52 are slidably inserted into the lifting base plate 51 via linear bearings, and the top of the lifting guide rods 52 is connected to the lifting plate 54. Four lifting guide rods 52 are arranged in an array to ensure the stability of the lifting. The bottom of the lifting plate 54 is connected to the piston rod of the lifting cylinder 53, and four lifting pins 55 are arranged in an array on the top of the lifting plate 54. Each lifting pin 55 corresponds one-to-one with a lifting positioning hole 411.

[0020] The insertion device 6 includes an insertion cylinder 65 and a test socket 67. The insertion cylinder 65 is fixed on one side of the conveyor 1 and connected to the test socket 67. The test socket 67 is matched with the wiring plug 92 of the compressor 9 and is used to insert into the wiring plug 92 so that the test instrument 8 and the compressor 9 can be electrically connected.

[0021] To facilitate adjustment of the position of the test socket 67 and accommodate compressors 9 of different specifications, the insertion device 6 also includes a three-axis moving device 61. The three-axis moving device 61 is mounted on a fixed base plate 41 on one side of the conveyor 1 and is connected to the insertion cylinder 65. The three-axis moving device 61 is composed of three linear modules, enabling linkage in the X, Y, and Z directions. An insertion base plate 68 is mounted on the three-axis moving device 61, and the insertion cylinder 65 is mounted on the insertion base plate 68. The insertion cylinder 65 is connected to an insertion seat 66, which is slidably mounted on the insertion base plate 68 via a linear guide pair and connected to the test socket 67. The insertion seat 66 is used to keep the axial position of the test socket 67 constant, improving the reliability and stability of the insertion.

[0022] To improve the accuracy of the lifting device 5 inserting into the fixed base plate 41, a booster device 3 is also included. The booster device 3 is installed on the conveyor 1 and is positioned opposite the positioning device 2, located on both sides of the fixed base plate 41. The booster device 3 is used to press the fixed device 4 onto the positioning device 2. The booster device 3 includes a booster cylinder 31 and a check assembly 32. The booster cylinder 31 is installed on the conveyor 1 via a booster seat. The check assembly 32 is mounted on the piston rod of the booster cylinder 31. The booster cylinder 31 is a sliding cylinder or a dual-shaft cylinder. The check assembly 32 is positioned opposite the positioning device 2. The check assembly 32 is an existing commercially available mature product and will not be described in detail here. The check assembly 32 facilitates the passage of the fixed base plate 41 while preventing the fixed base plate 41 from moving in the opposite direction, thus achieving a unidirectional conveying function.

[0023] During testing, the mounting hole 91 of the compressor 9 is aligned with the positioning post 42, and the mounting hole 91 is inserted into the positioning post 42. The bottom of the compressor 9 rests against the top of the support post 43 to fix the compressor 9. Then, the fixed base plate 41 is placed on the conveyor 1. The conveyor 1 drives the fixed base plate 41 and the compressor 9 to move towards the positioning device 2. The fixed base plate 41 slides over the top of the check assembly 32 and then moves to the blocking cylinder 21. The blocking cylinder 21 is in the extended state and blocks the fixed base plate 41. Then, the booster cylinder 31 is activated. The booster cylinder 31 drives the check assembly 32 to press the fixed base plate 41 tightly onto the blocking cylinder 21, achieving precise positioning of the fixed base plate 41. The lifting cylinder 53 is activated, which drives the lifting plate 54 and the lifting pin 55 to rise. The lifting pin 55 is inserted into the lifting positioning hole 411 and drives the fixed base plate 41 to rise to the set height so that the test socket 67 and the wiring plug 92 of the compressor 9 are coaxially aligned. Then the insertion cylinder 65 is activated, which drives the test socket 67 to be inserted into the wiring plug 92, completing the connection between the test instrument 8 and the compressor 9. Then the test instrument 8 starts the test.

[0024] After the test is completed, the blocking cylinder 21 retracts, the lifting cylinder 53 drives the fixed base plate 41 to descend, the fixed base plate 41 descends onto the conveyor 1, the lifting pin 55 separates from the lifting positioning hole 411, and the conveyor 1 drives the fixed base plate 41 to continue moving to the next test station. If four items need to be tested, the compressor 9 will lift and lower four times, and the tests of four different items will be completed on the same conveyor 1, which greatly shortens the overall test time, reduces the number of conveyors 1 and the floor space occupied, and realizes automated testing.

[0025] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
