The two groups of second pressure sensors 99 achieve a dynamic balancing pressure test effect on the rotor body 2 in the middle positioning state.

[0058] The working principle of a meat grinder rotor dynamic balance test device is as follows: first, the bolts 11 on the two sets of clamping seats 12 are screwed into the screw grooves 10 reserved at both ends of the rotor body 2, and then the clamping grooves 13 in the two sets of clamping seats 12 and the rotor body 2 are pre-connected to the clamping joints 14 on the two sets of first brackets 67, and the rotor body 2 is located on the inner side of the upper and lower test seats 79, and then the two first electric push rods 64 are controlled to open and drive the two sets of first driven bevel gears 63 to move inward to the meshing part of the driving bevel gear 62, and then the double-headed motor 61 is controlled to open and through the meshing The driving bevel gear 62 in place drives the two sets of first driven bevel gears 63 to rotate, and the two sets of first driven bevel gears 63 drive the two first threaded rods 65 to rotate accordingly. The two sets of first slide rail grooves 69 and the first slide rail blocks 610 play a sliding limit role on the two sets of first threaded sleeves 66. Then, the two first threaded rods 65 drive the two sets of first threaded sleeves 66 to move inward synchronously, and the two sets of first threaded sleeves 66 drive the clamping joints 14 on the two sets of first brackets 67 to clamp synchronously to the clamping grooves 13 in the two sets of clamping seats 12, so as to position the two ends of the rotor body 2.

[0059] After the two ends of the rotor body 2 have completed the positioning work, the double-headed motor 61 is first controlled to pause, and then the two first electric push rods 64 are controlled to close and the two groups of first driven bevel gears 63 are disengaged from the meshing part of the driving bevel gear 62 to the initial position, and then the first electric telescopic rod 71 is controlled to open and drive the driving circular gear 72 to move up to the meshing part of the four groups of driven circular gears 73, and then the double-headed motor 61 is controlled to be turned on again and the four groups of driven circular gears 73 are driven to rotate through the meshing driving circular gear 72, and the four groups of driven circular gears 73 drive the four forward and reverse screw rods 74. As the screw rods 74 rotate accordingly, the four forward and reverse screw rods 74 drive the four groups of screw rod sleeves 75 to move synchronously inward, and the four groups of screw rod sleeves 75 drive the four groups of light rods 77 on the support plates 76 to move synchronously toward the spiral tool holders on both sides of the rotor body 2, until the four groups of test seats 79 on the upper and lower sides cover the rotor body 2, and the spiral tool holders on both sides of the rotor body 2 are also inserted into the tool holder grooves 15, and the reset springs 78 provide elastic buffering and elastic reset cooperation for the light rods 77 on the four groups of test seats 79, so far, the pre-test preparation work of the rotor body 2 in the two-end positioning state is completed;

[0060] After the pre-test preparation work of the rotor body 2 in the two-end positioning state is completed, the double-headed motor 61 is controlled to pause again, and then the first electric telescopic rod 71 is controlled to close and drive the driving circular gear 72 to move down and disengage the meshing part of the four sets of driven circular gears 73 to the initial position, and then the two second electric telescopic rods 84 are controlled to open and drive the two sets of locking heads 85 to be clamped outward into the locking seats 86 on the two sets of main synchronous wheels 87, and then the double-headed motor 61 is controlled to be reopened and drive the rotating shaft 83 on the secondary bevel gear 82 to rotate through the main bevel gear 81. The rotating shaft 83 drives the two sets of main synchronous wheels 87 to rotate accordingly through the locking heads 85 and the locking seats 86 clamped in place at both ends. The two sets of main synchronous wheels 87 drive the two sets of tensioning wheels 88 and the clamping seats 12 on the two sets of belt grooves 89 to rotate through the two synchronous belts 810, and the two sets of clamping seats 12 drive the rotor body 2 in the two-end positioning state to rotate. The speed of the double-headed motor 61 can be controlled to realize the dynamic rotation of the rotor body 2 at different speeds. During the dynamic rotation of the rotor body 2 at different speeds, the first pressure sensors 68 on the two sets of first brackets 67 monitor the lateral offset pressure of the two end areas of the rotor body 2 in the two-end positioning state in real time, and the sway sensors 710 on the four sets of test seats 79 covering the test area of ​​the rotor body 2 monitor the radial offset pressure of the rotor body 2 in the two-end positioning state in real time. After completing the dynamic balancing pressure test and dynamic balancing sway test of the rotor body 2 in the two-end positioning state under different speed distribution conditions, the double-headed motor 61 is first controlled to pause, and then the two second electric telescopic rods 84 are controlled to close and drive the two sets of locking heads 85 to disengage from the locking seats 86 on the two sets of main synchronous wheels 87 inward to the initial position, and the dynamic rotation of the rotor body 2 is paused.

[0062] First, the double-headed motor 61 is controlled to pause, and then the two second electric push rods 93 are controlled to close and drive the two sets of second driven bevel gears 92 to disengage the meshing portion of the driving bevel gear 62 to the initial position, and then the double-headed motor 61 and the two second electric telescopic rods 84 are controlled to open again. Similarly, the two sets of tensioning wheels 88 and the clamping seats 12 on the two sets of belt grooves 89 are driven to rotate by the two synchronous belts 810 on the two sets of main synchronous wheels 87, and the two sets of clamping seats 12 drive the rotor body 2 in the middle positioning state to rotate, and the rotor body 2 is controlled to be distributed according to different speeds. Under the condition, the second pressure sensors 99 on the two sets of second brackets 96 are used to rotate the rotor body 2 in the middle positioning state. The lateral displacement pressure of the rotor body 2 in the middle positioning state is monitored in real time, and the radial displacement pressure of the rotor body 2 in the middle positioning state is monitored in real time by the shake sensors 710 on the four groups of test seats 79 covering the test area of ​​the rotor body 2. After completing the dynamic balance pressure test and the dynamic balance shake test of the rotor body 2 in the middle positioning state under different speed distribution conditions, the rotor body 2 is first controlled to stop, and the positioning seats 97 on the two groups of second brackets 96 are controlled to detach from the positioning groove 91 reserved in the middle of the rotor body 2 to the initial position. After the four groups of test seats 79 detach from the covering test area of ​​the rotor body 2, the rotor body 2 can be removed.
