Abstract
The present invention relates to a cam mechanism with a variable lift range. A cam is one of the basic mechanisms with wide application in mechanical engineering. The lift range of the existing cam is unchanged. The present invention relates to a novel cam mechanism, and the lift range of the cam mechanism can be conveniently and continuously regulated. A telescopic flexible cam is composed of a bending plate, a support rod, a core axle, a front axle sleeve, etc., and two pins arranged on a pull rod are respectively inserted into two spiral grooves in opposite directions of the core axle and the front axle sleeve; thus, when the pull rod moves in the axial direction, a relative angle between the core axle and the front axle sleeve can be changed, and the lift range of the cam can be continuously regulated. The cam mechanism of the present invention can be used for various drive devices, control devices and operation devices which need to change the lift range of the cam.
Description
The present invention is that a kind of mechanical structure, cam that can change cam lift is to use one of very wide basic system in the mechanical engineering.Existing cam must design and make according to the characteristics of motion that can make driven member do expection.It is the hard parts of shape invariance.After cam is contained on the equipment.Its lift be changeless, in some transmission, control and manipulator.Sometimes because of variation and other reason of product or testpieces, need the lift of cam to make corresponding changes, then can only pull down original cam, change the cam of another kind of lift, so not only very trouble, but also be difficult for accomplishing, want to continuously change the lift of cam, extremely difficult especially.
The purpose of this invention is to provide a kind of when fast rotational, can be easily the novel mechanism of adjustment cam lift continuously, it is made up of some parts, the cam that profile can change is different from existing rigid cam and can be described as flexible cam.
The present invention forms a kind of flexible cam that can stretch by parts such as twisted plate, supporting rod, mandrel, front shaft sleeve, rear axle housing and pins, the lift of this cam depends on mandrel that connects each supporting rod and the relative angle between the front shaft sleeve that connects twisted plate, and change the relative angle of mandrel and front shaft sleeve, thereby the lift of adjustment cam continuously with moving axially of pull bar.
Fig. 1 of accompanying drawing is the cam mechanism plan view of variable lift, and Fig. 2 is the sectional view along the A-A line.
By accompanying drawing as seen: a hole of twisted plate (1) is connected with rear axle housing (4) by the same front shaft sleeve of pin (6) (3).All the other each holes are connected with each supporting rod (2) by pin (10), the other end of each supporting rod is connected by the same mandrel of pin (10) (7), the same front shaft sleeve of thrust-bearing (5) is loaded onto at the mandrel two ends, rear axle housing matches and forms the relative angle of the variable cam mechanism of lift, change mandrel and front shaft sleeve, just can change the lift of cam.
The spiral chute that a left hand direction is arranged on the mandrel nose circle cylinder, the spiral chute that a dextrorotation direction is arranged on the front shaft sleeve cylndrical surface, two pins (8) insert respectively in two spiral chutes, and be pressed into pull bar (9), the axial position of mobile pull bar, the relative angle of mandrel and front shaft sleeve is changed, thus the lift of continuous adjustment cam.
The same with existing cam, the two ends of this cam mechanism match with the bearing on the extraneous bearing, can load onto gear or belt pulley on front shaft sleeve or rear axle housing, rotate so that transmit extraneous moment of rotation.
If the other end of pull bar is connected by motor-operated axial moving mechanism with extraneous, just can be in the mode of pressing a button, the lift of continuous adjustment cam easily.
The present invention can be used on the various transmissions that need to change cam lifts, control, the apparatus operating.
Claims (1)
- A kind of by plate, bar, multiple parts such as axle are movably connected to form the flexible cam that can change lift mutually, lift with the mode adjustment cam that changes two groups of relative angles between the part, it is characterized in that a hole on the twisted plate (1) is connected with rear axle housing (4) by the same front shaft sleeve of pin (6) (3), all the other each holes are connected with each supporting rod (2) by pin (10), the other end of each supporting rod is connected by the same mandrel of pin (10) (7), the bar spiral chute is arranged on the mandrel cylndrical surface, the reverse acting spiral groove is arranged on the front shaft sleeve cylndrical surface, two pins (8) insert respectively in two spiral chutes, and are pressed into pull bar (9).
