The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Fig. 1 is the top view of the utility model device, and in below describing, front end refers to the top direction among Fig. 1, and the left side refers to the left direction among the figure, and all the other directions by that analogy.
With reference to Fig. 1, the structure of the utility model fork governor motion is that fixing (welding) at base plate 1 has fixed head 2, is provided with locking slot in the fixed head 2; Base plate 1 and sliding seat 4 are flexibly connected by rotating shaft 11, are provided with lining 13 and rotating shaft 11 sockets in the shaft hole of sliding seat 4, can mutually rotate around rotating shaft 11 between sliding seat 4 and the base plate 1, and rotating shaft 11 two ends are provided with rotary shaft cover 14; Be fixed with Taper Pipe 12 at sliding seat 4 right side inwalls, corresponding locking slot has breach on the inner left wall of sliding seat 4;
Adjusting fork 16 passes forward sliding seat 4 rear walls and stretches into sliding seat 4 inner chambers, adjusting fork 16 stage casings in sliding seat 4 inner chambers are fixedly connected with lifting pressing plate 10 by steady pin 15, be set with swing pushing block 9 at adjusting fork 16 leading portion circumference, the front end of regulating fork 16 is sleeved in the 8-shaped groove that swings limit base 8;
Sliding seat 4 left side upper surfaces are provided with locking pressure plate 19, locking pressure plate 19 is fixed on sliding seat 4 sidewalls by four screws 17, be fixedly connected with on sliding seat 4 front side walls of locking pressure plate 19 belows and swing limit base 8, swing between limit base 8 and the locking pressure plate 19 and be provided with blockage;
Swinging pushing block 9 left sides stretches in the space between locking pressure plate 19 and the blockage;
Be provided with loose slot in the middle of the locking pressure plate 19, connecting screw rod 18 passes this loose slot and is fixedly connected with the stay 3 (right-hand member) of locking pressure plate 19 belows, the breach of the corresponding sliding seat 4 of the external end head of stay 3 (left end) and the locking slot position of fixed head 2; Locking pressure plate 19 fronts are equipped with reduction torsion spring 5 and locking torsion spring 7 along being provided with spring shaft 6 by spring shaft 6; One end of reduction torsion spring 5 wherein props up the inwall of sliding seat 4, and the other end is pushing tow connecting screw rod 18 left, gives 18 1 inside power of connecting screw rod (power of unclamping); One end of locking torsion spring 7 wherein props up the groove that swings pushing block 9 sides, and the other end to the right pushing tow connecting screw rod 18 is given 18 1 outside power of connecting screw rod (releasing the power that connecting screw rod 18 forms locking).
Stay 3 can stretch out from corresponding left end breach on the sliding seat 4 between locking pressure plate 19 and the sliding seat 4, and loose slot and stay 3 that connecting screw rod 18 passes in the middle of the locking pressure plate 19 are fixing, have limited stay 3 distance of stretch out and draw back to the left.Insert when stay 3 stretches out in the locking slot of fixed head 2, form the locking state between sliding seat 4 and the fixed head 2.Adopt this mode of braking to lock, played again simultaneously the effect of protection, the hand that can prevent the front-end operations personnel stretches into to cause in the mechanism and crushes.
When realizing lifting, Taper Pipe 12 is enclosed within the air pressure rod head, and lifting pressing plate 10 props up the air pressure rod end, and when fork 16 was regulated in rotation, lifting pressing plate 10 was pushed down the air pressure rod end and opened the air pressure rod switch, carries out lifting again.
After adjusting fork 16 passes base plate 1, sliding seat 4, swing pushing block 9 successively, head penetrates in the 8-shaped groove that swings limit base 8, when adjusting fork 16 is wanted to pull out, the side head of lifting pressing plate 10 has just propped up the inwall of sliding seat 4, limited and regulated pulling out of fork 16, this " fixed form " is because material is saved convenient fixing; Because regulating fork 16 can't pull out downwards, regulate fork 16 and be merely able between the 8-shaped groove that swings limit base 8, swing back and forth, make left side one end that swings pushing block 9, swinging between limit base 8, blockage and the locking pressure plate 19, the three has blocked swing pushing block 9, has limited its rotation.
The utility model fork governor motion operation principle is,
When oscillation adjustment fork 16, regulating fork 16 drive swing pushing blocks 9 moves to the left side along the 8-shaped grooves that swing in the limit base 8, driving swing pushing block 9 is moved to the left, when swinging pushing block 9 and propping up locking torsion spring 7 and move, the elastic force of locking torsion spring 7 is increased, and when the elastic force of locking torsion spring 7 during greater than the elastic force of reduction torsion spring 5, connecting screw rod 18 moves to left end along loose slot, connecting screw rod 18 drives stay 3 and moves together and insert in the locking slot of fixed head 2, and sliding seat 4 forms locking with fixed head 2;
Otherwise, such as the position among Fig. 1, when oscillation adjustment fork 16, regulating fork 16 drive swing pushing blocks 9 moves to the right along the 8-shaped grooves that swing in the limit base 8, when swinging pushing block 9 return, the external force of locking torsion spring 7 disappears, and the elastic force of reduction torsion spring 5 is greater than locking torsion spring 7, stay 3 is retracted into original position (loose slot right-hand member), and sliding seat 4 is in releasing orientation with fixed head 2.
