[0002] An existing patent (publication number: CN118670858A) discloses a frequency converter production testing device. It includes a mounting frame and support legs. A support rod is mounted on top of the mounting frame, a fixing rod is mounted on the upper part of the support rod, a cylinder is mounted at the bottom of the fixing rod, a push rod is mounted at the bottom of the cylinder, and a pressure detector is mounted at the bottom of the push rod. A first horizontal plate is mounted on the mounting frame, and second horizontal plates are mounted on both sides of the first horizontal plate. A first slider is mounted on the first horizontal plate, a first clamping plate is mounted on top of the first slider, and a first threaded rod is mounted on the first clamping plate. However, this device, with its "support rod on top of the mounting frame," relies on the pressure detector on the upper part of the mounting frame for production testing. The mounting frame is supported by the support legs. Since the mounting frame is of fixed height, it may not be possible to adjust its height according to the height of the inspector, making operation laborious and affecting the equipment's working efficiency. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a variable frequency drive (VFD) production and testing device. After the connecting plate at the bottom of the equipment column is installed at the bottom of the testing instrument, when the height of the worktable needs to be adjusted, a worm motor at the bottom of the lifting platform drives the worm gear to rotate. Simultaneously, the worm gear drives the worm wheel on the side of the camshaft to rotate, and the cam inside the camshaft rotates. This cam then drives the support roller frame at the bottom of the worktable to adjust its height. This allows the equipment to be adjusted according to the operator's actual needs, facilitating operation and increasing the adaptability of the equipment.

[0004] The objective of this utility model is achieved through the following technical solution: A frequency converter production and testing device includes a column, a connecting plate, a worm gear frame, a worm motor, a clamp frame, and a clamp seat. The lower part of the column is fixedly connected to the connecting plate, the upper part of the column is fixedly connected to a lifting platform, the side of the lifting platform is fixedly connected to a guide cylinder, the side of the worktable is fixedly connected to a guide rod, the guide cylinder is adapted to the guide rod, the guide cylinder is connected to the guide rod, the guide rod slides inside the guide cylinder, the lower part of the guide rod has a limit, the lower part of the lifting platform is fixedly connected to a camshaft frame, the side of the camshaft has a camshaft, the camshaft frame is adapted to the camshaft, the camshaft frame is connected to the camshaft, the camshaft rotates inside the camshaft frame, the side of the camshaft is fixedly connected to a worm gear, the side of the lifting platform has a drive cavity, the side of the drive cavity is fixedly connected to the worm gear frame, the worm gear frame is adapted to the worm, the worm gear frame is connected to the worm, the worm rotates inside the worm gear frame. Beneficial effects

[0005] 1. In the use of this utility model inverter production and testing device, after the connecting plate at the bottom of the equipment column is installed to the bottom of the testing instrument, if it is necessary to adjust the height of the worktable, the worm motor at the bottom of the lifting platform drives the worm to rotate, which in turn drives the worm wheel on the side of the camshaft to rotate, and at the same time drives the cam inside the camshaft to rotate, so that the cam drives the support roller frame at the bottom of the worktable to adjust the height. Thus, the equipment can adjust the height of the worktable according to the actual needs of the operator, making it convenient for the staff to operate and increasing the adaptability of the equipment.

[0006] 2. During the use of this inverter production and testing device, the worm gear motor at the bottom of the lifting platform drives the cam to rotate, which in turn drives the support roller frame at the bottom of the worktable to rise and fall. At the same time, the support roller at the bottom of the support roller frame rotates inside the cam groove on the side of the cam, reducing friction during lifting and increasing the service life of the equipment.

[0007] 3. During the use of this inverter production and testing device, the worm motor drives the internal worm gear to rotate, which in turn drives the worm wheel to rotate. Because the transmission principle of the worm and worm wheel has a self-locking function, the equipment can maintain the adjusted height even when the power is off, thereby enhancing the stability of the equipment.
