Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to the effort-saving mechanism of a kind of automobile welding and assembling clamp shown in Fig. 1-3, comprise: a linking arm 5, switching member 6, connecting plate 2, handle 1, it is characterized in that: one end of described linking arm is fixedly connected on below cylinder assembly 7 left parts, described linking arm 5 other ends are flexibly connected with the left side of connecting plate 2 bottoms; The right side of described connecting plate 2 bottoms is connected with the threaded one end of handle 1; The left side of described switching member 6 is fixedly connected on the right side of cylinder assembly 7, and this switching member 6 coordinates with described connecting plate 2 upper ends.
Further, the other end of described linking arm is provided with a through hole 51, the left side of described connecting plate 2 bottoms is provided with shaft hole 22, one rotating shafts 4 through the through hole 51 on described linking arm 5 and the shaft hole 22 of connecting plate 2 bottoms, realizes the hinged of described linking arm 5 and connecting plate 2.
Further, the upper end of described connecting plate 2 is provided with one " U " shape bayonet socket 21, the right lower quadrant of described switching member is provided with the anti-rotating shaft 3 of a via hole 61, and coordinates with the via hole 61 on described switching member 6, and " U " shape bayonet socket 21 and the described anti-rotating shaft 3 of described connecting plate 2 upper ends adopt matched in clearance.
Further, the axial line that described handle 1 other end is greater than described anti-rotating shaft 3 to the distance L 1 of the axial line of rotating shaft 4 is to the distance L 2 between the axial line of rotating shaft 4.
Further, described linking arm 5 is " Z " shape.
Shown in Figure 3: handle 1 is applied to downward pressure, through transmission mechanism, act on anti-rotating shaft 3, realize the motion of horizontal direction with dynamic air cylinder guide rod 9, stretch out thereby realize alignment pin 8, returning by air-channel system control cylinder of alignment pin 8 realizes auto-returned.Because adopting, this mechanism manually puts in place, pneumatic returning, and motion is reliable, and this mechanism is without dead point.The masterpiece that this winding machine applies vertical direction, for horizontal direction, has solved the problem of some privileged site operating difficulties.
Shown in Figure 4: changeover mechanism 6 and alignment pin 8 horizontal sliding mechanisms such as composition such as accessory structure such as grade.
Suppose to promote the required lowest pull F=100N of cylinder, ignore the minute angle existing in this mechanism poor, this mechanism is regarded as to the motion of complete level,: at anti-rotating shaft 3 places, rotating around it of connecting plate, ignores the micro-displacement of anti-rotating shaft at vertical direction, simultaneously, ignore friction: the power F3=F that acts on horizontal sliding mechanism;
At rotating shaft 4 places, the power F2 that handle is applied and connecting plate 2 form one group of trimming moment M,
Have: M=320* F2=160 F3
So, F2=0.5F=50N
1.
Shown in Figure 5: suppose not adopt this mechanism, change employing level into and pull the pattern of cylinder, level pulls the required tensile force f 1 of cylinder can be through calculating as follows:
Suppose to promote the required lowest pull F=100N of cylinder,
: F1=F=100N 2.
