Digital cam signal device with variable angle

Abstract

The invention relates to an angle-changeable digital CAM signal device comprising an input display device, a digital control device and a photoelectric encoder (62). The input display device is connected with the digital control device which is connected with the photoelectric encoder (62), a pulse signal of the photoelectric encoder (62) is inputted into a high-speed pulse port of the digital control device, the digital control device digitizes the pulse signal of the photoelectric encoder (62) into an angle value, the input display device inputs a CAM signal angle value to the digital control device, the digitized angle value is compared with the inputted CAM signal angle value, and a CAM signal is generated inside the digital control device. The digital CAM signal device is intelligent, convenient, changeable in angle and quite convenient and intuitive to operate, cost is lowered and saved greatly, and use efficiency of a machine is prolonged.

Description

[technical field] [0001] The invention relates to the technical field of CAM cam angle signals, in particular to a digital CAM signal device with changeable angles. [Background technique] [0002] The CAM in the general sense is the mechanical cam commonly used in the machinery industry. In order to control various actions in the mechanical production process, it is necessary to convert the angle signal corresponding to the raised part of the CAM into an electrical signal. The traditional CAM signal device can be simply attributed to CAM+micro switch, or CAM+proximity sensor, see attached image 3 And attached Figure 4 ; CAM along the center of the circle or CAM signal relationship, please refer to the attached Figure 5 , that is, the raised portion of the CAM along the center of the circle is the ON signal in the CAM signal relationship diagram (or OFF signal on the contrary), and the two are consistent. [0003] Among them, the CAM+ micro switch is cheap, but because ...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the installation of physical mechanical cams, to increase the CAM signal, it is necessary to add mechanical cams and corresponding micro switches or proximity sensors, as well as on-site mechanical installation and electrical wiring;

[0005] (2) Once the CAM is manufactured, the width range of its signal cannot be adjusted; if you want to adjust the width, you must manufacture a new CAM;

[0006] (3) The initial position adjustment of the CAM signal must be adjusted manually. Generally, it takes several repeated attempts to adjust it.

[0010] (2) Since it is a special device or equipment, a special manual or instructions are required, and non-professional users must undergo special training before using it;

[0011] (3) Also because it is a special device or equipment, there will be some redundant functions for a specific machine, which is not convenient for the training and understanding of the users;

[0012] (4) Also because it is a special device or equipment, the cost of use is high;

[0013] (5) Because the CAM signal needs to be connected to the machine control system, the number of electrical connection points increases, which increases the failure rate of the equipment together with itself
