when the hardness standard machine starts to operate, a standard hardness block is installed in a notch 514 on a second panel 512, a first linear motor 521 is started, a first secondary 523 drives a transition plate 610, a second linear motor 620 and a first panel 511 to horizontally move, the first panel 511 drives the second panel 512 to move into the hardness standard machine, when an induction plate 531 passes through a last proximity switch 532, the proximity switch 532 sends a position signal to a first primary 522, and the first primary 522 controls the first secondary 523 to stop moving, so that the standard hardness block is positioned at the lower end of a lower main shaft 375.

The rotating motor 421 drives the screw rod lifting member 422 to operate under the control of the computer program, and the screw rod lifting member 422 drives the connecting plate 410 to vertically move, so that the connecting plate 410 can just abut against the lower end face of the second panel 512.

First motor 311 drive worm gear lead screw lift operation, worm gear lead screw lift drives the vertical rebound of weighing sensor 323, weighing sensor 323 drives connecting block 322 vertical movement, connecting block 322 drives bearing block 321 vertical movement, bearing block 321 drives locating lever 333 vertical movement, locating lever 333 drives first bearing block 331 vertical movement, first bearing block 331 drives three first bearing bar 332 vertical movement, make first bearing bar 332 drive second bearing block 341 and three second bearing bar 342 vertical movement, second bearing block 341 drives third bearing bar 154 vertical movement, thereby drive the vertical removal of top weight 150.

When weight 150 moves vertically, weight 150 takes place relative displacement with the sliding block 162 in the chamber 151 that slides earlier, makes sliding block 162 move vertically downwards in the chamber 151 that slides, and when sliding block 162 supported tightly with the lower wall of the chamber 151 that slides, weight 150 drove sliding block 162 and sliding rod 161 vertical displacement simultaneously, makes sliding rod 161 drive the adjacent weight 150 vertical migration in below to can be continuous increase the quantity of weight 150 on the bearing block 321.

When the weight of the weight 150 meets the requirement, the weighing sensor 323 respectively sends signals to the first motor 311 and the second motor 211, the second motor 211 is started and keeps synchronous operation with the first motor 311, the second motor 211 drives the first gear commutator 131 to operate, the first gear commutator 131 drives the two second gear commutators 132 to operate, the second gear commutator 132 drives the worm gear reducer 212 to operate, the four worm gear reducers 212 respectively drive the four second lead screws 230 to simultaneously rotate, the second lead screw 230 drives the moving plate 220 to vertically move, the moving plate 220 drives the weight 150 which does not exert the gravity on the bearing block 321 to move upwards, the weight 150 which does not exert the force on the bearing block 321 keeps relatively static with the weight 150 which exerts the force adjacent to the upper part, and the distance between the two weights 150 is smaller than the height of the sliding cavity 151 in the weight 150 on the upper part, so that the force exerted on the bearing block 321 is unchanged.

When the bearing block 321 reaches a designated height, the first motor 311 drives the worm gear screw elevator to operate in a reverse direction, so that the descending speed of the connecting block 322 is greater than that of the bearing block 321, and meanwhile, the second motor 211 moves in a reverse synchronous manner, so that the moving plate 220 drives the weight 150 which does not exert gravity on the bearing block 321 to move downwards, and the force exerted on the bearing block 321 drives the lower main shaft 375 to move downwards.

The lower main shaft 375 contacts with the standard hardness block, the lower main shaft 375 stops moving and relatively displaces with the upper main shaft 360, the limiting block 371 moves upwards in the accommodating groove 361 and compresses the buffer spring 372, when the upper end face of the limiting block 371 contacts with the groove bottom of the accommodating groove 361, the elastic force of the buffer spring 372 can reduce the impact force generated by the upper main shaft 360 on the lower main shaft 375, meanwhile, the inertia force generated in the descending process of the upper main shaft 360 can be reduced, and the force received by the standard hardness block is close to the force received by the bearing block 321.

After the main shaft 375 leaves under the driving of the first motor 311, the second sub-stage 622 drives the first panel 511 to move horizontally, the first panel 511 drives the second panel 512 to move horizontally, and the second panel 512 drives the standard hardness block to move, so that different positions of the standard hardness block can be detected.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
