[0019] like Figure 1 to Figure 3 As shown, the utility model provides an inverter FCT test equipment, including a frame 1, an upper test mold 7 movably installed on the frame 1, a lower test mold 8 installed in the frame 1, a lifting frame 5 movably installed on the frame 1 through a lateral moving module 9 and an electric cylinder 10, a tray 6 placed on the lifting frame 5, and a test piece placed on the tray 6.

[0020] The transverse moving module 9 drives the lifting frame 5 to move forward and backward, and the electric cylinder 10 drives the lifting frame 5 to move up and down. When the tested piece needs to be placed, the tray 6 is sent out through the transverse moving module 9, and the staff places the tested piece on the tray 6, and then the tray 6 is retracted through the transverse moving module 9; further, a positioning piece is provided on the tray 6, and a through hole is provided on the tested piece at the position corresponding to the positioning piece.

[0021] The testing equipment in the prior art is generally suitable for small test pieces. When the test piece is too large, it is inconvenient for the staff to place the test piece in the test mold. Therefore, this device is designed; between tests, the tray 6 is transported out horizontally, and the staff only needs to align the test piece with the positioning piece and place it on the tray 6, which facilitates the staff's operation and ensures the accuracy of the test position of the test piece.

[0022] After the transverse moving module 9 retracts the tray 6, the electric cylinder 10 drives the lifting frame 5 to move downward. When the lifting frame 5 moves down to under the lower test mold 7, the tray 6 and the workpiece to be tested will be left on the lower test mold 8; further, a positioning hole will be provided on the tray 6, and a limit column will be provided at the position corresponding to the positioning hole of the lower test mold 8; because during the test process, the movement of the lower test mold 8 will cause inaccurate test results, the lower test mold 8 is fixedly installed on the frame 1 in this device.

[0023] Specifically, the lifting plate 12 is movably mounted on the frame 1 through the electric cylinder 11, and at the same time, the lifting plate 12 is symmetrically mounted with slide rails 13. The upper test mold 7 is movably mounted on the lifting plate 12 through the slide rails 13. When the upper test mold 7 needs to be replaced, the upper test mold 7 can be pulled out; at the same time, a sensor 14 is installed on the lifting plate 12, and the sensor 14 is used to detect whether the upper test mold 7 is placed in place to avoid affecting the subsequent detection quality.

[0024] Furthermore, a display screen 3 , an alarm light 2 and a button 4 are also installed on the frame 1 .

[0025] The display screen 3, the warning light 2, the button 4, the electric cylinder 2 11, the electric cylinder 1 10, the upper test mold 7, the lateral moving mold 9, the lower test mold 8 and the sensor 14 are communicatively coupled to the control panel.

[0026] The control panel contains a PLC controller, which can program the numerical control system. The PLC is used as the central control system, and the touch screen is used to realize the program input and operation control of the whole machine, so as to realize the full automation of the transportation process. The control system can be used as a system that connects various actuators to move according to the logical trajectory, and the actuators can be controlled by programming to run according to the required operation steps.

[0027] The working principle of the utility model is:

[0028] Press button 4, and the lateral moving module 9 will send out the lifting frame 5, and the workpiece to be tested will be manually placed in the tray 6 of the lifting frame 5, and the tray 6 will be retracted by the lateral moving module 9; then the lifting frame 5 will be driven down by the electric cylinder 10, and the tray 6 and the workpiece to be tested will be left on the lower test mold 8; then the upper test mold 7 will be driven down by the electric cylinder 2 11 to test the workpiece to be tested, and the test result will be fed back to the display screen 3, and if the result is unqualified, the alarm light 2 will light up; when the test is completed, the electric cylinder 10 cooperates with the lateral moving module 9 to send out the workpiece to be tested.

[0029] The device can ensure the accuracy of the test piece during testing, and is convenient for testing large test pieces, and is convenient for workers to place large test pieces, thereby improving work efficiency and test accuracy.

[0030] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
