Embodiment 1

[0035] The liquid crystal display circuit and the keyboard scanning circuit are directly connected with the I / O port of the single-chip microcomputer to display the force value, input the setting data, and realize a friendly man-machine interface. The analog-to-digital conversion chip is connected to the microcontroller through a two-wire I2C, namely the data line (SDA) and the clock line (SCL), to achieve high-precision acquisition. The functions of pulling force collection and pulling force display are realized by programming the single-chip microcomputer (C8051F350) and the system CPU (ATmega64) used for analog-to-digital conversion respectively.

[0036] The specific hardware circuit is:

[0037] a) Hardware circuit (ATmega64 module)

[0038] LCD liquid crystal display unit

[0039] Such as figure 2 As shown, the LCD liquid crystal display part of this system is realized through liquid crystal display controllers KS107 and KS108, KS107 is the row driver, and KS108 is t...

Abstract

The invention relates to a manual simple tensile machine, which comprises a mechanical part and a singlechip control system, wherein the mechanical part comprises a machine case, a foundation bracket,a turntable bracket, a clamp plate, a wire clamping device and a handle; and the upper part of the machine case is provided with the wire clamping device, the clamp plate and the turntable bracket, and the lower part of the machine case is provided with the foundation bracket. The manual simple tensile machine has the advantages that the mechanical part is designed flexibly and conveniently and is labor-saving to operate, the control precision is at the same level of that of foreign products in performance, the operation interface is Chinese localized to be suitable for domestic use habits, and the cost is low and has absolute advantage compared with the foreign products.

Description

【Technical field】 [0001] The invention relates to the technical field of tension machines, in particular to a simple manual tension machine. 【Background technique】 [0002] With the rapid development of digital technology, the close combination of mechanical technology and electronic technology has formed mechatronics technology. The combination of mechatronics and software has brought about great changes in the technical structure, product organization, function and composition, production mode and management system of the machinery industry, and has made products move towards intelligence, modularization, networking, miniaturization, and green and systematic development. The simple and easy tension machine of the present invention is exactly the typical representative of this technology. [0003] There is still a blank controller technology in China that can switch between the three control modes of displacement-test force-deformation without impact, and the accuracy of ...
