Embodiment Construction

[0015] Such as figure 1 Shown is a hardware architecture diagram of a preferred embodiment of the machine speed change motion control system of the present invention. The system includes: a computer 1 , an axis control card 2 , a machine 3 and a joystick system 4 . The rocker system 4 includes a handle control card 40 and a rocker 41 .

[0016] The computer 1 is connected with the handle control card 40 through its RS232 serial line or USB port, and is used to calculate the deflection of the rocker 41 connected to the handle control card 40, and set the movement speed and direction of the machine 3. Specifically, when the operator operates the rocker 41, the rocker 41 sends an analog signal to the handle control card 40; the handle control card 40 converts the analog signal into a digital signal and sends it to the computer 1; the computer 1 According to the digital signal, the moving speed and moving direction of the machine table 3 are set. Wherein, the rocker 41 includes...

Abstract

The invention relates to a method for controlling the variable motion of a machine stand. The method comprises the following steps: the corresponding parameters of variable motion of a machine stand are set; when a rocker is moved, the deflection degree A of the rocker is obtained; when A is higher than zero, the pulling direction of the rocker is set to be related with the direction of positive movement of a moving component; when A is less than zero, the pulling direction of the rocker is set to be related with the direction of negative movement of the moving component; the movement velocityof the moving component is calculated according to A; when the moving component is in the first deceleration range, the movement velocity of the moving component is set to be V1; a shaft control cardcontrols the moving component to move according to V1 and the set direction of movement; when the moving component is in the second deceleration range, the movement velocity of the moving component is set to be V2; the shaft control card controls the moving component to move according to V2 and the set direction of movement; and when the moving component reaches a spacing position, a stop instruction is sent to the shaft control card, and the shaft control card controls the moving component to stop moving. Besides, the invention also provides a system for controlling the variable motion of the machine stand.

Description

technical field [0001] The invention relates to a variable speed motion control system and method. Background technique [0002] Quality is one of the important factors for an enterprise to maintain its long-term development ability. How to ensure and improve product quality is an important part of enterprise activities. Before mass production of products, the manufacturing plant needs to measure the produced samples to check whether there are quality problems, such as whether the size and shape of the workpiece are within the tolerance range. At present, this measurement method is mostly done by human using measuring tools , manual operation has large errors, low efficiency and difficult to guarantee accuracy. [0003] With the development and application of computer technology, measurement technology is no longer limited to manual operations, and computers are widely introduced in workpiece inspection activities, which improves the accuracy of inspection. When measuring ...
