As shown in fig. 14, the present invention adopts a crank link mechanism as a transmission mechanism of motor transmission, and the design calculation method and process are as follows:
force F transmitted from the eccentric to the connecting rod 1 Force F 'in vertical direction with slider' 1 The following relationships exist:
F′ 1 ＝F 1 cos(β) (1)
eccentric wheel to connecting rod connection point A, force F in radial direction 3 And F 1 The following relationships exist:
F 3 ＝F 1 cos (. alpha. +. beta.) (2) brings (1) into (2) and gives:
force F of the eccentric in the tangential direction 2 The product with the radius is the torque:
M＝F 2 ·r (4)
according to the force analysis in the figure, the following results are obtained:
F 2 ＝F 1 sin(α+β) (5)
bringing (1) and (5) into (4) to obtain:
the length of the connecting rod in a common crank-connecting rod mechanism is generally much larger than the radius of the eccentric wheel. I.e., L > r, then the angle beta can be considered zero degrees in this case. The above equation can be written as:
M＝F′ 1 ·r·sin(α) (7)
the device with simplified kinematic characteristics of the central crank-link mechanism is shown in fig. 15:
according to the Pythagorean theorem of the plane geometric circle part, the following can be derived:
bringing (8) into (7) then gives:
point o is the central point of the eccentric wheel, point a is the connecting point of the connecting rod and the eccentric wheel, point B is the end position of the connecting rod (the motion track of the extrusion head is the same as point B, so only the kinematic track of point B is analyzed), point AD is the auxiliary line, and AD is perpendicular to oB, r is the radius of the eccentric wheel, L is the length of the connecting rod, and s is the amplitude of point D.
Assuming that at a certain moment, the eccentric wheel rotates to the position shown in the figure, the angle between the connecting line of the point A and the point B and the vertical line is alpha, and the angle between the connecting line of the point B and the point C and the vertical line is beta. The formula is as follows:
S＝R+L-Rcosα-Lcosβ＝R(1-cosα)+L(1-cosβ) (10)
simultaneously:
Rsinα＝Lsinβ (11)
defining:
then there is the following trigonometric function:
bringing 13 to 10 results in:
since in a crank mechanism the speed is varied periodically. Wherein the instantaneous velocity is the differential of the displacement with respect to time, and the instantaneous acceleration is the differential of the instantaneous velocity with respect to time, then the velocity and acceleration are respectively:
through the stress analysis condition of the crank-link mechanism, the stress conditions of the extrusion rod and the transmission rod and the change conditions of speed and acceleration can be deduced, and the specific analysis is as shown in the following figure 16:
the calculation process is as follows:
and the speed and acceleration change conditions of the extrusion rod and the transmission rod are obtained through the speed and acceleration change of the crank-link mechanism:
finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, while the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the invention as defined by the appended claims.
