Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1 to 3, the utility model discloses a precision torque angle testing mechanism, including base plate 1, locate fixed clamping component 2 and the rotary clamping component 3 above base plate 1, fixed clamping component 2 includes the first centering anchor clamps 21 that the level set up and a pair of fixed clamping jaw 22 by the drive of first centering anchor clamps 21, rotary clamping component 3 includes that the axis is located the torque sensor 31 in the symmetry plane of first centering anchor clamps 21, control torque sensor 31 around vertical axis rotatory servo motor 32 and the level is fixed in the second centering anchor clamps 33 above torque sensor 31, second centering anchor clamps 33 drive a pair of symmetry plane through the rotary clamping jaw 34 of torque sensor 31's axis. During operation, travel switch 4's one end is by the centre gripping between two fixed clamping jaw 22, and the other end is by the centre gripping between two rotatory clamping jaw 34, then servo motor 32 drive second centering anchor clamps 21 rotatory and twist reverse travel switch 4, can obtain angle information through servo motor 32, can obtain torque information through torque sensor 31, just so can judge travel switch 4 and whether reach the precision standard.
As shown in fig. 1, the first centering jig 21 is adjustably fixed above the substrate 1 by the elevating mechanism 11. Since the travel switch 4 itself has a certain height, the height of the fixed jaw 22 needs to be finely adjusted in order for the torsion to occur in a plane perpendicular to the axis of the torque sensor 31 for more accurate torque verticality. In practical applications, the lifting mechanism 11 is not limited to the cross-bar lifting mechanism shown in the drawings, and other ways may be adopted to achieve the purpose.
As shown in fig. 2, the fixing jaw 22 has an elongated hole 221 provided parallel to the symmetry plane of the first centering jig 21, and the fixing jaw 22 is fixed to the first centering jig 21 by a screw passing through the elongated hole 221. The fixing clamping jaw 22 can adapt to the lengths of different travel switches 4, so that the travel switches 4 can be firmly fixed during testing and are prevented from loosening.
As shown in fig. 1 and 2, the torque sensor 31 is externally provided with a protective sleeve 35. The protective sleeve 35 can provide support for the first centering jig 21 and protect around the torque sensor 31 to prevent gravity from affecting the accuracy of the torque sensor 31.
As shown in fig. 2 and 3, the inside of the rotating jaw 34 is provided with a pad 341. The washer 341 allows the rotating jaw 34 to be in sufficient contact when gripping the travel switch 4 to prevent pulling off or damaging the travel switch 4 surface.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
