Description
Technical field
It the utility model is related to a kind of double rack retaining mechanism and large-scale heavy duty lotus motion platform system.
Background technology
Big machinery equipment is the development trend of current mechanized equipment, is played in some specific area big machineries equipment
Irreplaceable effect.Big machinery equipment load is big, complicated, production cycle length, can go out during design and use
The problem of being now difficult to prediction, this design equipped to big machinery propose higher requirement.Retaining mechanism is one kind large-scale
Relatively conventional mechanism in mechanized equipment, it is often required that in big machinery equipment can undertake bigger load and impact
Power, and can realize and be accurately positioned and lock.The locking method and advantage and disadvantage of retaining mechanism common at present are as follows：
Utilize the frictional force for locking module：It is simple in construction, it is easy to be analyzed, but for very big load, applying
When pressing longitudinal loading, its load will be provided by frictional force completely, and this will propose higher requirement to the normal pressure on contact surface, lead
Cause locking module volume excessive, it is excessively heavy, increase cost.
Bearing pin：Stress is clear and definite, is easy to analyze, and is divided into rectangle bearing pin and circular bearing pin, and wherein rectangle bearing pin is easy between elimination
Gap, circular bearing pin be not easy to eliminate gap, bearing pin is primarily subjected to shearing action, in the case where load is larger, bearing pin size compared with
Greatly, while between pin-and-hole enough distances are needed to carry out load, so mode is to have level adjustment, and gap is larger between level.
Leading screw：Effectively undertake larger radial direction and axial direction static load, dynamic load, be applied in combination can also bear it is larger
Moment of flexure, but equipped for big machinery, the diameter of leading screw can be dramatically increased, makes manufacture difficult or even can not manufacture, cost increase.
Common retaining mechanism can only apply to the plateform system of small-sized low-load in the market, and may not apply to big
The motion platform system of type heavy load.For large-scale heavy duty lotus motion platform, then higher requirement is proposed to retaining mechanism,
Ask locking property reliable and secure, retaining mechanism locking method common at present is difficult to meet that big machinery is equipped in big load
Locking and positioning requirements under operating mode.

The virtual number of teeth that movable teeth carries simultaneously calculates
Movable teeth tooth form is as shown in figure 14, and movable teeth stress is as shown in figure 15, and analysis calculates its bending resistance, tooth root section
Composite bending modulus is：
Tooth root section turn moment is：
In formula：
F is the maximum load that monodentate is born；B is the facewidth, B=800mm；B1 is that tooth root is thick, b1=110mm；H is the high h of tooth
=65mm.
Bending strength:
Solve：F=2615.6t
Because the maximum load of movable teeth is Fz；
[(moving beam is certainly for 10800 (Z-direction cylinder outputs) -330 (weighted platform deadweight) -200 (test specimen deadweight) -360 by Fz=
Weight) -320 (retaining mechanism gross weights)] * 1.2 (uneven load coefficient)/4 (retaining mechanism quantity)=2877 ≈ 2900t
Therefore need while the virtual number of teeth of carrying is：
N=FZ/F=2900/2615.6=1.11
Consider 2 times of safety coefficient, then the virtual number of teeth for needing to carry simultaneously is 2.22, meets to require.
Analytic activity tooth shear resistance
It is known：
τ is shear stress, MPa；Q is monodentate bearing load, t；A_j is tooth root area of section, mm2；SS is material yield
Intensity, SS=550MPa.
Calculate：Q=2677t
The virtual number of teeth for then needing to carry simultaneously is：
N=FZ/Q=2900/2677=1.08
Consider 2 times of safety coefficient, then the virtual number of teeth for needing to carry simultaneously is 2.16, meets to require.
The calculating of upper wedge inclined-plane degree
The effect of upper wedge in retaining mechanism：It is pushed into during loading, eliminates gap between movable teeth and holding frame, resistance activity
The rotation of tooth, the structure of upper wedge are as shown in Figure 9.Upper wedge bevel angle depends on confficient of static friction.The force diagram of upper wedge
As shown in figure 16, the calculation formula of inclined-plane degree is as follows：
F1cosθ+F2sinθ-F3=0
F1sinθ-F4-F2Cos θ=0
F2=fF1
F4=fF3
Obtain
Retaining mechanism holding frame serves not only as retaining mechanism and moving beam connector, and the positioning base of retaining mechanism
It is accurate.Due to moving beam overall processing, want to ensure that the precision of retaining mechanism locating surface is more difficult.Therefore in retaining mechanism holding frame
Adjusting pad is set between the horizontal location face and perpendicular positioning face of moving beam, reconditioning and match grinding by adjusting pad, ensured
The final precision of movable rack.
Reference plane of the vertical plane that definition retaining mechanism holding frame outer surface is connected with moving beam as processing and measurement.
Disappear gap inclined-plane and lower positioning plane on being set between movable teeth and holding frame, when movable rack fully retracted state as initial
Positioning states.
The design of nylon slide block
Primary election nylon slide block appearance and size is 400x280x35 (mm), takes 2 times of safety coefficients, [σ]=100/2=50Mpa,
Then maximum load capacity is：
F=[σ] × S=50 × 400 × 280=560t
Maximum compressibility is：
Δ h=h × [ε]
[ε]=[σ]/E
In formula：Δ h is maximum compressibility, mm；[ε] is strain；E is MC nylon elastic modulus, 3.6GPa；Calculate：Δh
=0.48mm.
Then, unilateral maximum pre compressed magnitude is 0.24mm, just be can guarantee that between movable teeth and nylon slide block device, while complete
Full compression, do not crack on one side, occur without gap.Then maximum precompression is：
F=[σ] * S
Calculate：F=276.5t
Upper voussoir driving cylinder pulling force
The effect of upper voussoir is that locking is realized in the space being inserted between movable teeth and holding frame, is needing moving beam
When, upper voussoir driving cylinder needs enough pulling force and pulls out upper voussoir, and the maximum clamping force of upper voussoir is calculated as follows：
In formula：1. maximum axle pressure；2. weighted platform weight；3. test specimen weight；4. moving beam weight；5. retaining mechanism weight
Amount；6. rise cylinder pulling force；7. load nonuniformity coefficient.
As shown in figure 11, each holding claw front end, in working condition, is held Driven by Hydraulic Cylinder tightly and held tightly tiltedly equipped with wedge is held tightly
Wedge, eliminate the gap for holding that wedge and fixing tooth back inclined-plane are reserved tightly, it is therefore an objective to increase coupling stiffness, transmit test piece torque.It is flat
When cohesion device wedge and column stationary rack back inclined-plane retain certain interval, when crossbeam to be moved moves up and down, rise lead
To effect.
Large-scale heavy duty lotus motion platform system number of assembling steps is as follows：Upper wedge driving cylinder and movable teeth driving cylinder are fixed in guarantor
Hold inframe portion → guide rail is installed → and go up wedge and driving cylinder in wedge and lower liner plate installation → movable teeth installation → connection；Movable teeth
Be fixed in the mounted part of driving cylinder → on moving beam by pull bar → holding claw is fixed in locking machine by pull bar
On structure → hold driving cylinder tightly and be fixed in up and down on holding claw.
The operation principle of motion platform system is as follows：Step 1, lift cylinder driving moving beam rise or fall, using swash
Optar judges that movable teeth reaches the position of engagement；Step 2, movable teeth driving cylinder driving movable teeth and fixing tooth are at a fully engaged good
It is good；Step 3, locking is realized in the space that the upper upper voussoir of voussoir driving cylinder driving is inserted between movable teeth and holding frame.
Each technical characteristic of above-mentioned disclosure is not limited to disclosed and further feature combination, and those skilled in the art are also
Other combinations between each technical characteristic can be carried out according to the purpose of utility model, are defined by the purpose for realizing the utility model.
