Specific embodiment
Below in conjunction with attached drawing and technical solution, a specific embodiment of the invention is further illustrated.
The basic circle of disk cam 1 is using cam contour minimum radius as circle made by radius in cam, it is cam -train
One important parameter of system rule design.The profile rule of cam is equivalent on the basis of basic circle, corresponding in different corners
Under, basic circle outer profile radially carries out adaptable transformation relative to the centre of gyration.Point is driven by outer profile in the movement of disk cam 1
The driven members such as top, flat-top, roller, and then realize displacement law.
As shown in Figure 1, basic circle setting disk 2 is embedded in disk cam 1, basic circle setting disk 2 is matched with disk cam 1 for transition
Connection is closed, while carrying out gap control, controls gap within 0.05mm；Basic circle setting disk 2 on be provided with hook knob 4,
Lower hook knob 5, cam revolution mounting hole 6 and tuning drive gear 7；The center that cam turns round mounting hole 6 is the centre of gyration of cam；
The fixing end of tuning drive gear (7) is fixed on cam revolution mounting hole (6) edge in basic circle setting disk (2)；Upper hook knob 4
Head with lower hook knob 5 is taper stud, is symmetrically arranged above and below tuning drive gear 7, for locking
The basic circle for being completed setting sets disk 2, is integrated basic circle setting disk 2 and the locking of disk cam 1；Graduation indication disk 3 is sleeved on
Basic circle sets 2 outer profile of disk, is located on disk cam 1, and graduation indication disk 3 is 0~360 ° of indexing, and minimum division value is 1 °,
In, 0 ° corresponds to the smallest position of basic circle, and maximum base circle position is determined by cam rule；By the way that basic circle to be set to the quarter on disk 2
Degree pointer 7 rotates to the setting of basic circle needed for setting position is completed.
As shown in Fig. 2, the upper and lower ends of cam mounting disc 8 are equipped with hollow pipe column, centre is mounting disc；Cam mounting disc 8
Upper end hollow pipe column be sleeved on cam teaching equipment rotary motion output shaft docking end, pass through mounting disc holding screw 9
Transmission shaft in locking insertion upper end hollow pipe column；The outer circle of the hollow pipe column of 8 lower end of cam mounting disc is used for and cam revolution
The cooperation assembly of mounting hole 6, the hollow pipe column inner hole of lower end are threaded, and are turned round mounting hole 6 by being threadedly engaged cam, are synchronized
Disk cam 1 and the locking of cam mounting disc 8 are integrated by locking washer 10 and genlocing bolt 11, are realized and are rotated synchronously.
As shown in figure 3, upper locking taper pin 12 compresses upper lock return spring 13, the upper rotation of hook knob 4 is to drive locking
The translation of taper pin 12 is determined, so that basic circle setting disk 2 and the locking of disk cam 1 are integrated；When loosening, upper locking taper pin 12 is being locked
Determine to disengage under the effect of reset spring 13 with disk cam 1, the disk 2 of basic circle setting at this time unlocks with disk cam 1.Together
When, it is acted on as shown in figure 4, the lower locking taper pin 14 of the cooperation of lower hook knob 5 compresses lower lock return spring 15, realizes basic circle setting
The locking and disengaging of disk 2 and disk cam 1.
When basic circle is set, loosen upper hook knob 4 and lower hook knob 5 first, rotates freely basic circle setting disk 2；Root
According to the base radius of required setting, tuning drive gear 7 is rotated to the angle of a certain determination.For the foreign steamer of typical cam
Wide rule is established to obtain the corresponding relationship of rotation angle and base radius using analytic method, and then obtains the angle for needing to rotate；
Single parsing corresponding relationship can not then be established out for regular complicated cam, at this moment the angle and base by establishing out in advance
The table of comparisons of radius of circle determines rotation angle.When setting, table only need to be compareed, according to the size of required basic circle, finding is needed
Tuning drive gear 7 is rotated to setting position by the angle to be arranged.After being provided with, upper hook knob 4 and lower locking are revolved
Button 5 is tightened, and basic circle setting disk 2 and the locking of disk cam 1 are integrated.Mounting hole 6 is turned round by cam again and cooperates genlocing
Disk cam 1 and the locking of cam mounting disc 8 are integrated by gasket 10 and genlocing bolt 11, to realize synchronous rotation.
The present invention illustrates realized function by taking experimental teaching as an example, and the methods being previously mentioned are used in other fields,
Realize similar functions and the scope of the present invention.
