AI Technical Summary

Problems solved by technology

The existing cam teaching equipment, especially the experimental cams, are all parameterized. After the manufacturing is completed, the parameters are uniquely determined and cannot be changed in the system, which brings inconvenience to the modification of relevant parameters in the experimental teaching and the research of cam characteristics.

Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0024] The base circle of the disc cam 1 is a circle made in the cam with the minimum radius of the cam profile, and it is an important parameter for the regular design of the cam system. The contour law of the cam is equivalent to the transformation of the outer contour of the base circle relative to the radial direction of the center of rotation under different rotation angles on the basis of the base circle. During the movement of the disc cam 1, the outer contour drives the driven parts such as the pointed top, the flat top, and the roller, so as to realize the regularity of displacement.

[0025] Such as figure 1 As shown, the base circle setting disc 2 is embedded in the disc-shaped cam 1, and the base circle setting disc 2 and the disc-shaped cam 1 are in a transition fit connection, and the gap is ...

Abstract

The invention belongs to the technical field of theories of mechanical mechanisms. A base circle configurable disk cam train comprises a disk cam, a base circle setting disk, a dial indicator, an upper locking knob, a lower locking knob, a cam rotatable mounting hole, a scale pointer, a cam mounting disk, a mounting disk locking screw, a synchronous locking pad, a synchronous locking bolt, an upper locking taper pin, an upper locking reset spring, a lower locking taper pin and a lower locking reset spring. According to the base circle configurable disk cam train, a base circle is set through the base circle setting disk, the dial indicator and the scale pointer; the upper locking knob and the lower locking knob integrally lock the disk cam and the base circle setting disk; the cam rotatable mounting hole cooperates with the synchronous locking pad and the synchronous locking bolt to integrally lock the disk cam and the cam mounting disk. The base circle configurable disk cam train realizes precise setting of the base circle of the disk cam, is simple in structure, can adjust the parameters of the base circle at any time, has a locking function, and can ensure that the parameters set by the cam are unchanged during mounting and measurement.

Description

technical field [0001] The invention belongs to the technical field of mechanical principles and mechanisms, and relates to a cam mechanism, in particular to a disc-shaped cam device with a settable base circle. Background technique [0002] The cam has a simple and compact structure, through which a variety of complex movements can be realized, and it is widely used in mechanical equipment. Cam mechanism is a difficult point in the teaching of mechanical principles. Its content is abstract and difficult for students to learn, especially when it comes to the comprehensive application of relevant knowledge. Combined with experimental teaching, it can greatly facilitate students' learning of relevant knowledge. [0003] The law of the disc cam is determined by the edge profile of the outer contour, and the rotation of the cam pushes the linear or oscillating follower to generate a predetermined movement, and then realize the required law. The existing cam teaching equipment,...
