Detailed Description
The utility model is further described with reference to the following figures and detailed description. As shown in fig. 1-4, the clamping mechanism of the motor dynamometer comprises a clamping back plate 1, two clamping connection blocks 2 and two clamping compression rods 3, and a motor 7 is positioned between the two clamping compression rods 3 and the two clamping connection blocks 2. Two strip-shaped back plate mounting holes 11 are formed in the clamping back plate 1, and the mounting screws 4 penetrate through the back plate mounting holes 11 and are fixed with the clamping connecting blocks 2. The mounting screw 4 is screwed down to fix the clamping connecting block 2 and the clamping back plate 1; when the position of the clamping connection block 2 needs to be adjusted, the mounting screw 4 is unscrewed, at the moment, the mounting screw 4 and the clamping connection block 2 can move along the elongated back plate mounting hole 11, and the mounting screw 4 is screwed again after the adjustment is finished. The mounting screws 4 are matched with the strip-shaped back plate mounting holes 11 to adjust the distance between the two clamping connection blocks 2, so that the clamping device can be suitable for motors with different sizes.
In the above technical scheme: a pressure bar groove 21 is formed on the clamping connecting block 2, and strip-shaped pressure bar mounting holes 22 are formed in the groove walls on the two sides of the pressure bar groove 21. The clamping pressure rod 3 is positioned in the pressure rod groove 21, one end of the clamping pressure rod 3 is provided with a pin hole 32, one end of the clamping pressure rod 3 is provided with an arc-shaped sliding guide surface 31, and the sliding guide surface 31 is close to the pin hole 32.
