Description

Technical Field

[0001] This utility model relates to the field of EMC test turntable technology, specifically to an adjustable linkage type EMC test turntable. Background Technology

[0002] The purpose of EMC testing is to detect the impact of electromagnetic radiation generated by electrical products on the human body, public power grids, and other normally functioning electrical products. A control system can control coordinate axes including translational and rotary axes. The basic translational axes are x, y, and z axes, and the basic rotary axes are a, b, and c axes. A linked axis refers to the number of coordinate axes that the CNC system can control to move simultaneously according to machining requirements. For example, a certain model of CNC machine tool has three coordinate axes (x, x, z), but the CNC system can only control movement in two coordinate directions (xy, yz, or xz) simultaneously. Therefore, the machine tool has 3 control axes (called three-axis control) and 2 linked axes.

[0003] Existing EMC test turntables can achieve free control of the x, y, and z axes. However, some special products require multi-directional testing. Existing turntables have limited functionality and lack clamping devices, while multi-axis linkage requires clamping and fixing devices.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The test turntable is provided with a servo motor one for driving the rotating shafts. The U-shaped connecting seat is provided with a servo motor two for driving the test platform to rotate. The test platform is provided with a fixing mechanism for clamping products.

[0008] Preferably, the fixing mechanism includes four sets of L-shaped clamps located on the top of the test platform. The bottom end of each L-shaped clamp is provided with a pin that is movably connected to the test platform. The end of each pin is provided with a connector, and the bottom end of the connector is movably connected to an inclined connecting rod.

[0009] Preferably, the bottom end of the connecting rod is movably connected to a connecting piece, the connecting piece having a triangular structure, and the bottom of the connecting piece is movably connected to a fixing block that is fixedly connected to the side of the test platform.

[0010] Preferably, one side of the connecting piece is movably connected to a connecting rod extending into the test platform, and the other end of the connecting rod is provided with a sliding shaft that is movably connected. The test platform is provided with a sliding hole that matches the sliding shaft.

[0011] Preferably, the test platform has a horizontally arranged frame, and both sides of the frame are movably connected to movable rods corresponding to the four sets of sliding shafts.

[0023] According to an embodiment of the present invention, an adjustable linkage EMC test turntable is provided.

[0024] Example 1:

[0025] like Figure 1-4 As shown, the adjustable linkage EMC test turntable according to an embodiment of the present utility model includes a test turntable 1 and a test platform 2. The bottom of the test turntable 1 is provided with a U-shaped connecting seat 3 that is movably connected. The two sides of the U-shaped connecting seat 3 are provided with rotating shafts 4 that are movably connected to the test turntable 1. The test turntable 1 is provided with a servo motor 5 that drives the rotating shafts 4. The U-shaped connecting seat 3 is provided with a servo motor 6 that drives the test platform 2 to rotate. The test platform 2 is provided with a fixing mechanism for clamping products.

[0026] Example 2:

[0027] like Figure 1-4As shown, the fixing mechanism includes four sets of L-shaped clamping rods 7 located on the top of the test platform 2. The bottom end of each L-shaped clamping rod 7 is provided with a pin 8 that is movably connected to the test platform 2. The end of each pin 8 is provided with a connector 9. The bottom end of each connector 9 is movably connected with an inclined connecting rod 10. The bottom end of each connecting rod 10 is movably connected with a connecting piece 11. The connecting piece 11 has a triangular structure, and the bottom of the connecting piece 11 is movably connected with a fixing block 12 that is fixedly connected to the side of the test platform 2. One side of the connecting piece 11 is movably connected with a connecting rod 13 that extends into the test platform 2. The other end of the connecting rod 13 is provided with a sliding shaft 14 that is movably connected. The test platform 2 has a sliding hole 15 that matches the sliding shaft 14.

[0028] Example 3:

[0029] like Figure 1-4 As shown, the test platform 2 is provided with a horizontally arranged frame 16.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In practical applications, when the device is started, the servo motor 5 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the test platform 2 to rotate through the U-shaped connecting seat 3. The test platform 2 has a fixing mechanism. When the product is placed on the test platform 2, the hydraulic cylinder 18 is started to drive the frame 16 to move upward. The frame 16 drives the connecting rod 13 to move in opposite directions in the sliding hole 15 with the sliding shaft 14 as the pivot point. This causes the connecting rod 13 to push the connecting piece 11 to rotate with the top of the fixing block 12 as the pivot point. This causes the top of the connecting piece 11 to push the connecting rod 10. The connecting rod 10 pushes the L-shaped clamping rod 7 to rotate in the same direction with the pin shaft 8 as the pivot point through the connecting piece 9. This causes the L-shaped clamping rod 7 to clamp and fix the product.

[0032] In summary, with the help of the above-mentioned technical solution of this utility model, through the setting of the fixing mechanism, the frame 16 drives the connecting rod 13 to move in opposite directions in the sliding hole 15 with the sliding shaft 14 as the axis, so that the connecting rod 13 pushes the connecting piece 11 to rotate with the top of the fixing block 12 as the axis, so that the top of the connecting piece 11 pushes the connecting rod 10, and the connecting rod 10 pushes the L-shaped clamping rod 7 to rotate in the same direction with the pin 8 as the axis through the connecting piece 9, thereby making the L-shaped clamping rod 7 clamp and fix the product. It can be adjusted according to the size of the specific product. The product and the clamping device itself are fixed by the extension and retraction of the hydraulic cylinder 18, saving the time of disassembling the fixing device.
