1, in existing teaching, mainly by trace-point method, draw the displacement curve of cam follower, the method complex operation, efficiency is low.
2, by software simulation, must have abundant cam model data just can draw out cam face, and the sense organ of software simulation is not strong.
By the analysis to current existing cam locus measuring method, conventional method function ratio is more single, loaded down with trivial details, complicated.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
For addressing the above problem, the deficiency of measuring by contrasting existing cam locus, the utility model provides a kind of difunctional formula cam locus plotter.This device has simple, easy to use, the steady feature such as safe, with low cost of compact conformation, technique.
The technical solution adopted in the utility model is:
A kind of difunctional formula cam locus plotter, this cam locus plotter comprises frame, table mechanism, table-driving mechanism, cam disk mechanism, cam disc driving group and transfer bar mechanism, described table mechanism comprises workbench and is arranged on the tooth bar on workbench, described table-driving mechanism comprises driven wheel, driving shaft and table drive motor, described driven wheel is installed on driving shaft, described driving shaft is by table drive motor driven rotary, and the tooth bar on described driven wheel and workbench meshes; Described cam disk mechanism comprises cam fixed head and simulation cam, described simulation cam is fixed on cam fixed head, described cam disc driving group comprises driving shaft and cam disc drive motors, and described cam fixed head is fixed on driving shaft, and described driving shaft is by cam disc drive motors driven rotary; Described transfer bar mechanism bottom contacts with simulation flank of cam, on described transfer bar mechanism, paintbrush is set.
Described workbench hangs in frame, and described transfer bar mechanism and cam disk mechanism are positioned at the workbench back side.
Described frame is divided into upper and lower two-layer, and the upper end of described transfer bar mechanism, lower end are all socketed with L-type support, and two L-type support lower ends are individually fixed in support upper strata and support lower floor.
Operation principle: realize the drafting of cam follower displacement curve and the drafting of cam face:
1,, by two motors, cam disc drive motors control cam follower moves up and down and table drive motor is controlled moving left and right of workbench, draws cam follower displacement curve.
2, use the pen of hand control push rod upper end, and travelling table, pen is moved by cam follower trajectory, and Electric Machine Control disk is with corresponding rotational speed, on disk, draws out corresponding cam profile.
The beneficial effects of the utility model: this device is mainly by frame, table mechanism, table-driving mechanism, cam disk mechanism, cam disc driving group and transfer bar mechanism, and this device is realized the drafting of cam follower displacement curve and the drafting of cam face.
