Problems solved by technology
[0004] The horizontal reversing locking device applied to ground equipment is relatively mature, but there are few literature reports on its application to the horizontal reversing locking device of centrifuge specimens
And due to the special stress state under the centrifuge, such devices on the ground equipment cannot be copied to the centrifuge

Embodiment Construction
[0028] The present invention will be further described below in conjunction with accompanying drawing:
[0029] Such as figure 1 As shown, the horizontal reversing locking device for the centrifuge test piece of the present invention includes a rotating test stand 2 for installing the test piece (not shown in the figure), and the rotating arm 1 of the centrifuge is provided with a mounting hole ( figure 1 not shown), the rotating test bench 2 is installed in the mounting hole through a fixing device, figure 1 Two rotating test benches 2 are shown in , and the number and positions in practical applications are determined according to requirements. Such as figure 2 As shown, the top of the rotary test bench 2 is provided with a "T"-shaped groove 4 for installing the test piece; the lower section of the rotary test bench 2 is a conical surface 6 with a large upper part and a smaller lower part. This conical surface structure makes the rotary test bench 2 and The contact betwe...

The invention discloses a centrifugal machine test-piece horizontal reversing locking device. The centrifugal machine test-piece horizontal reversing locking device comprises a rotary test platform used for installing a test piece. An installment hole is formed in a rotary arm of a centrifugal machine; the rotary test platform is installed in the installment hole through a fixing device; the fixing device comprises a reversing pin and a locking module; a pin groove is formed in the position, close to the edge of the rotary test platform and the center of the rotary arm, on the rotary arm; the reversing pin is arranged in the pin groove and can move; a handle extending out of the rotary arm is arranged on the reversing pin; a pin hole matched with the reversing pin is formed in the edge of the rotary test platform; the rotary test platform and the rotary arm are locked and fixed through the locking module. The horizontal angle of the rotary test platform is fast positioned through the reversing pin, the reversing pin will stay in the pin hole all the time under the action of centrifugal force, and will not move, the rotary test platform and the rotary arm are fast locked and loosened through the locking module, and accordingly reversing and locking operation can be fast and conveniently conducted on the rotary test platform and a test piece.
Description
technical field [0001] The invention relates to a horizontal reversing locking device for a test piece of a centrifuge, in particular to a horizontal reversing locking device for a test piece of a centrifuge which can simply and quickly change the horizontal angle of the test piece. Background technique [0002] Routine test centrifuges and precision centrifuges are two important components of centrifuges. Routine test centrifuges are mainly used for ultra-gravity testing of components. This kind of testing usually requires high acceleration accuracy, and they are all in large batches. They have high requirements for the operability and ease of use of the centrifuge. Precision centrifuges are used for the calibration of linear accelerometers for inertial navigation and inertial guidance. The "Calibration Specifications for Precision Centrifuges for Linear Accelerometers" stipulates the accuracy requirements for the installation angle of linear accelerometers for precision ce...
