A space spiral motion device

Abstract

The invention discloses a spatial helical motion device including a base table and a control case and also including a linear displacement module. One side of the linear displace module is provided with a first power control line. Linear reciprocating motion of the device is realized through a program set for the control case. A rotary mechanism disposed above the linear displacement module moveslinearly in a reciprocating manner along with the linear displacement module. The rotary mechanism is provided with a second power control line. The rotation motion of the device is realized through the program set for the control case. The motion direction of the linear displacement module is parallel to the axial direction of the rotary mechanism. When the rotary mechanism moves linearly in a reciprocating manner along with the linear displacement module, the rotary mechanism enables the rotation motion of the device at the same time. The simultaneous motion of the linear displacement moduleand the rotary mechanism enables the spatial helical motion. According to the invention, helical motion of fixed parameters and variable parameters can be realized. The flexibility is high, the drivestructure is simple and collected data accuracy is high. Therefore, requirements for the helical motion device of different motion parameters are met.

Description

technical field [0001] The invention relates to the technical field of screw motion devices, in particular to a space screw motion device. Background technique [0002] In the field of machinery manufacturing and testing, it is often necessary to use a kinematic device that combines rotational motion and linear motion at the same time. For example, in thread processing, thread parameter detection, and other tasks, kinematic devices that combine rotational motion and linear motion are used. , at present, the mechanism devices that realize compound motion are all realized by mechanical transmission. Most of the intermediate transmission parts (such as belts, gears, lead screws, etc.) are used between the motor and the actuator. It will bring a certain amount of transmission error, not only has the defects of complex structure, high cost, and high failure rate, but at the same time, the motion parameters of this compound motion device are generally fixed, and only one or a few ...
