The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
As shown in Figure 1 to Figure 3, this geometric parameter changeable type camming movement displacement curve drawing instrument, comprises
Bracing or strutting arrangement, it comprises holder 1, is arranged in turn frame 2, sliding rail rack 3 and two whiteboard brackets 4 on holder 1;
Belt gear, comprise the motor 5 being arranged in frame 2, be arranged on motor 5 motor shafts middle parts before, latter two driving wheel 15 and four belts 17, two whiteboard brackets 4 upper, the lower end pair of driven 16 that all be arranged in parallel, every pair of driven pulley 16 is all arranged on the both sides, front and back of whiteboard bracket 4 by power transmission shaft, article two, belt 17 every be all enclosed within the upper of whiteboard bracket 4 front portions, on lower driven pulley 16, two other belt 17 every be all enclosed within the upper of a driving wheel 15 and two whiteboard bracket 4 rear portions, on lower driven pulley 16, be enclosed within the upper of whiteboard bracket 4 front portions, on two belts 17 on lower driven pulley 16, be fixed with blank 18, blank 18 is along with belt 17 moves up and down,
Cam drive, comprise by trip bolt 8 be arranged on motor 5 motor shaft ends removable cam 6, be arranged on the roller follower 9 of cam 6 outers, cam 6 has chute I 7 with the junction of motor shaft; And
Carriage, comprise the slide rail 12 being arranged on sliding rail rack 3, slide rail 12 is provided with chute II 11, in chute II 11, be provided with the slide block 10 that can move horizontally, slide block 10 left ends connect roller follower 9, slide block 10 right-hand members connect pencil 14 by pencil support 13, and slide block 10 can move horizontally along slide rail 12 by the motion of cam 6.
Pencil 14 contacts with blank 18 all the time.
Operation principle is: motor 5 is active force, drives removable cam 6 to rotate by motor 5 motor shaft runnings, and slide block 10 moves left and right along slide rail 12 under the drive of cam 6, thereby moves left and right on blank with the pencil 14 of movable slider 10 right-hand members; When motor 5 motor shaft running, can drive driving wheel 15 to rotate, drive driven pulley 16 to rotate by power transmission shaft, two belts 17 that drive is enclosed within on the upper and lower driven pulley 16 of whiteboard bracket 4 front portions move, thereby drive blank 18 to move up and down, in the time that cam 6 rotates one week, motor 5 stops, end-of-job.Now, pencil 14 can leave movement locus on blank 18, i.e. the moving displacement curve of cam 6 for this reason.
The drafting of whole moving displacement curve is all completed by pencil 14, and its movement locus staying on blank 18 is the moving displacement curve when front cam 6, and blank 18 is finished and can takes off, and the analysis of carrying out kinematic parameter is used.Whole process can allow student grasp more intuitively the kinetic characteristic of cam 6.
In addition, cam 6 is convenient for changing, and can realize the function of drawing multiple different cam profile moving displacement curve, mainly realizes by following two kinds of methods:
1, under same cam 6 profiles, by adjusting eccentric throw, realize the replacing of different cams 6,, in the time that needs are adjusted, unscrew trip bolt 8, along chute I 7 directions, translating cam 6, after selecting a suitable position, tightens trip bolt 8, realizes location;
2, chute I 7 is matching relationship with removable cam 6, need to change time, as long as removable cam 6 is taken out along motor shaft direction, changes the cam 6 of other profiles.
The above-mentioned specific embodiment is only concrete case of the present utility model, be not the restriction of the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But under every prerequisite that does not depart from the utility model know-why, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, all should fall into scope of patent protection of the present utility model.
