The linkage mechanism comprehensive experiment apparatus is characterized in that the four hinge pins are all convenient to assemble and disassemble, the center of the disc and the position of a point to which the distance from the center of the disc is equal to pitch of the two hinge pins on one rod member are respectively provided with one through hole or gap matched with the hinge pin, the disc can be hinged to one slide block and another rod member after being overlapped with the rod member, the locking members are arranged on side surfaces of the chutes on the frame or the slide blocks for locking or releasing the slide blocks, thereby forbidding or allowing the slide blocks to slide freely along the chutes, therefore, the linkage mechanism comprehensive experiment apparatus of the utility model can realize a plurality of mechanism deformations, and can help students understand the evolution of the mechanism, eccentric circle mechanism kinematic diagram drawing, conditions for the mechanism to have a determined motion, etc.
Description
Technical field
The utility model relates to a kind of education experiment apparatus, particularly a kind of linkage assembly integrated demonstration experimental device, and it can be deformed into five-rod, four-bar mechanism, eccentric mechanism, slider-crank mechanism or elliptical mechanism etc.
Background technology
The application of linkage assembly is very extensive, and it often appears in numerous industrial and agricultural machineries and engineering machinery.Therefore, linkage assembly is one of most important mechanism of mechanical principle or Fundamentals of Machine Design learning.As there is the condition of crank in the ABC of planar linkage mechanism, the fundamental type of four-bar linkage and evolution mode etc. thereof becomes the heavy difficult point in teaching.
For this reason, there are some to develop some experimental provisions and assist learning aid.As ZL201220000685.6 and ZL201310501665.6, but the disclosed device of these patents, the length that can only change simply rod member is demonstrated the fundamental type of crank, be directly to overlap out various evolution results by complicated mode and formation, process, the drafting eccentric mechanism kinematic sketch etc. of student being understood to evolution help little.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, a kind of brief but remarkable integrated experimental device is provided, it not only can be for the demonstration of the fundamental type of four-bar linkage and evolution result thereof, more can help some evolutionary processes of classmate's intuitivism apprehension, and the method for expressing of eccentric wheel in kinematic sketch of mechanism, can also be used for owing the demonstration of drive system.
In order to achieve the above object, the utility model adopts following technical scheme:
Linkage assembly comprehensive experimental device of the present utility model, comprise frame, a disk, two slide blocks, three rod members, four hinge pins and some lock pieces, three rod member series connection are hinged, head and the tail two bar outer ends are each hinged with a slide block, two slide blocks are embedded in respectively in frame in orthogonal two chutes, it is characterized in that all convenient mounting or dismounting of four hinge pins, disc centre and with it distance equal two hinge pin pitch-row point places on a bar respectively through hole or a breach that can coordinate with hinge pin, this disk is hinged with a slide block and another rod member again after can be overlapping with this rod member, lock piece is arranged on the side or slide block of frame upper hopper chute, be used for locking or loosen slide block, thereby forbid or allow slide block to be free to slide along chute.
Three described rod member length can equate also can be unequal.
Described can have multiplely for controlling the whether movable lock piece of each slide block, can be screw or latch.
The beneficial effects of the utility model are:
1. simple in structure, cost is low.
2. distortion is many, powerful.Main distortion has:
A) plane six-bar linkage;
B) planar five-bar mechanism;
C) meet the four-bar mechanism that has crank condition;
D) do not meet the four-bar mechanism that has crank condition;
E) centric slider-crank mechanism;
F) offset slider-crank mechanism;
G) eccentric mechanism;
H) elliptical mechanism.
3. except can be used for the teaching of linkage assembly, also can be used for the teaching of kinematic sketch of mechanism, also can be used for mechanism and have the teaching demonstration of definite moving condition.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, linkage assembly comprehensive experimental device of the present utility model, comprise frame 1, a disk 7, two slide blocks 3 and I 4, three rod members 4, 9 and 11, four hinge pins 6, 10, 13 and 17, lock piece 5, 8, 12 and 15, three rod member series connection are hinged, head and the tail two bar outer ends are each hinged with a slide block, two slide blocks are embedded in respectively in frame in orthogonal two chutes 2 and 16, it is characterized in that all convenient mounting or dismounting of four hinge pins, disk 7 centers and with it distance equal two hinge pin pitch-row point places on bar 4 respectively through hole or a breach that can coordinate with hinge pin, disk 7 is hinged with slide block 3 and rod member 9 again after can be overlapping with rod member 4, lock piece is arranged on the side or slide block of frame upper hopper chute, be used for locking or loosen slide block, thereby forbid or allow slide block to be free to slide along chute.Concrete variant embodiment is as follows:
As Fig. 1, shown in 2, if all lockings not of lock piece 5 and 12 form six-bar mechanism;
If one of them locking, forms five-rod;
If two equal lockings, become four-bar mechanism, now meet the condition of crank of existing, as become crank and rocker mechanism taking bar 4 as former driving link, as taking bar 11 as position that driving link can be used for demonstrating dead point concept and appearance thereof;
If slide block 14 be moved to the left and by the equal locking of two slide blocks, as shown in Figure 3, be now double rocker mechanism;
Locking lock piece 5 in Fig. 5, unclamps 12, becomes offset slider-crank mechanism; Load onto disk 7 (Fig. 4) and be easy to imagine eccentric mechanism, be convenient to understand hinge dimensions and become the mechanism evolution principle causing greatly, and why eccentric wheel be expressed as the line segment of eccentric distance in kinematic sketch of mechanism, can also be used for explaining the now quickreturn characteristics of slide block;
In Fig. 6, slide block 3 is moved on to another location, locking 8, unclamps 12, becomes centric slider-crank mechanism, now the not anxious phenomenon of returning;
In Fig. 8, lock piece all unclamps, and becomes elliptical mechanism, becomes ellipsograph.
Above-mentioned embodiment is used for the utility model of explaining; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim; all the utility model is taked to be equal to replace or technical scheme that equivalent transformation obtains, all fall into protection domain of the present utility model.
