Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment 1：As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, a kind of hydraulically operated fixture floating compacting machine
The workpiece 2 of half built-in, including rotation binding clasp 3, institute are provided with structure, including workpiece locating piece 1, described workpiece locating piece 1
It is provided with to be provided with main pressing plate 4, described main pressing plate 4 in the rotation binding clasp 3 stated and mutually rolls the floating briquetting being connected with main pressing plate 4
5, described floating briquetting 5 is abutted against with the spring-loaded plunger 6 being located in main pressing plate 4；
Mutually activity is crimped described floating briquetting 5 with workpiece 2.
The top of described floating briquetting 5 provided with bulb 7 with the main phase rotational positioning of pressing plate 4, described floating briquetting 5
Top is provided with the chute 8 that is mutually slidably connected with spring-loaded plunger 6, and breach is crimped provided with workpiece in the bottom of described floating briquetting 5
9, the top of described workpiece crimping breach 9 is provided with the vertical bearing surface 10 abutted against with workpiece 2, described workpiece crimping breach
9 side is provided with the horizontal bearing surface 11 abutted against with workpiece 2.
Described horizontal bearing surface 11 and vertical bearing surface 10 are in arc-shaped respectively.
Binding clasp is rotated in Fig. 2, when not pressing to bottom, under the effect of spring-loaded plunger elastic force, floating briquetting is pasted with main pressing plate
Together.
Binding clasp is rotated in Fig. 3, during pushing, when floating briquetting is contacted with workpiece, floating briquetting is made by workpiece is counter
Firmly, start to rotate around fulcrum.
Binding clasp is rotated in Fig. 4, when reaching final compacted position, workpiece is with floating briquetting in level, vertical both direction
Contact, workpiece is simultaneously by, the clamping force under vertical direction, and the clamping force of horizontal direction to the right.In floating briquetting and workpiece
In the presence of horizontal contact face, the upward active force produced to floating briquetting, floating briquetting has around its fulcrum, counterclockwise rotation
The trend turned, so that, in the vertical contact position of workpiece and floating briquetting, produce the power of level to the right.
In Fig. 6,
Fx--- main pressing plate is made a concerted effort to floating briquetting horizontal direction；
Fy--- main pressing plate is made a concerted effort to floating briquetting vertical direction；
F'x--- workpiece is to floating briquetting horizontal direction active force；
F'y--- workpiece is to floating briquetting vertical direction active force；
Fk--- spring-loaded plunger is to floating briquetting vertical direction active force；
G1--- floating briquetting is conducted oneself with dignity.
In Fig. 7,
l'x——F'xThe arm of force；
l'y——F'yThe arm of force；
lk——FkThe arm of force；
lg1——G1The arm of force.
(2) Shi Ke get more than：
In above force analysis, not by the frictional force of main pressing plate and floating briquetting, it is considered to inside.Meanwhile, actual conditions
Under, G1、FkCompared to Fy、F'x、F'y, can be much smaller, it can be ignored, therefore calculation formula, it can be reduced to：
Wherein, FyIt is approximately equal to thrust when oil cylinder is pushed again.
In Fig. 8, when oil cylinder is not pushed, spring-loaded plunger produces torque Fklk>G1lg1, therefore floating briquetting can be depressed into and master
Pressing plate is sticked together.(consider the face of cylinder frictional force F of main pressing plate and floating briquettingfIf, Fklk>G1lg1+FfR)。
