Eccentric wheel combination 635 in wall, the panel assembly 6311 that beats include beaing plate 6312, are fixed on and described beat plate 6312 or so
Both sides brace 6314 and be fixed on it is described beat the top of plate 6312 push away fitting 6313, the left and right sides brace 6314 leaves
The side of plate 6312 of beaing is fixedly connected with the guide block 6322 of the left and right sides respectively, and the eccentric wheel combination 635 is located at
In the described 3rd recessed access slot 631 for pushing away the left side of fitting 6313, it is described push away the left side top of fitting 6313 be installed with to institute
The bending section 6315 that eccentric wheel combination 635 compresses sliding cooperation is stated, work is beaten so as to realize to automatically control, reduces worker's work
Amount, improve the operating efficiency of keyboard strength test.
During original state, the press block 623 of the left and right sides at utmost leaves the second recessed access slot 62 of the side of projection 621
It is interior, now, push away connecing block 634 and compressed power by the first spring element 6344, make to push away connecing block 634 and at utmost put in the second recessed access slot
In 62, meanwhile, by pushing away the top position for connecing block 634 and driving trolley shoe 63 to be located in the first recessed access slot 61, now, the left and right sides
The outer ledge of first slope face 6341 at respectively with compressing sliding match somebody with somebody at the inside edge of the second slope 6231 of the left and right sides
Conjunction state, meanwhile, the plexor member 6331 in trolley shoe 63 is fully located in the first recessed access slot 61.
When needing to flatten and beat work, test machine 6 is moved to by the road surface for needing to beat by base 5 first
Top position, then the screw rod 624 of the left and right sides is driven to rotate simultaneously by the first engine 622, by the screw rod of the left and right sides
624 drive the press block 623 of the left and right sides to relatively move respectively, now, the second slope on left and right sides press block 623
6231 compress with pushing away the first slope face 6341 connect on the left and right sides of block 634 be slidably matched respectively, and then, by supporting for the left and right sides
The relative movement of briquetting 623 drive push away connect that block 634 overcomes the first spring element 6344 compress power slide downward, meanwhile, connect block by pushing away
634 drive trolley shoes 63 gradually gradually slide along the bottom direction in the first recessed access slot 61, until the left and right sides of trolley shoe 63
Plexor member 6331 is skidded off outside the bottom surface of test machine 6, and now, the first engine 622 of control stops operating, then by controlling base 5
Move left and right, meanwhile, control eccentric combination 635 rotates counterclockwise, by eccentric wheel combine 635 compress with bending section 6315 it is sliding
Coordinate, because guide block 6322 by the elasticity of the second spring element 6323 is compressed power, 635 combines with bending by eccentric wheel so as to realize
Portion 6315, which compresses to be slidably matched, drives that beats that panel assembly 6311 overcomes the second spring element 6323 to compress power upward sliding, works as bias
When wheel combination 635 completely disengages bending section 6315, so as to realize by the elasticity by guide block 6322 by the second spring element 6323
Power is compressed, and then the realization of the slide downward of panel assembly 6311 is beaten by the drive of guide block 6322 and beats work automatically, at that time eccentric group
When conjunction 635 persistently rotates counterclockwise, and then realize that beaing the continuous of panel assembly 6311 back and forth beats work.
The beneficial effects of the invention are as follows：
1. accordingly set first slope face at left and right sides of block by pushing away to connect, push away connecing the second relative recessed access slot inner roof wall of block top and consolidate
