Buffer type contact force active control multi-purpose operation equipment

Abstract

Buffer type contact force active control multi-purpose operation equipment comprises a linear driving mechanism, a buffering mechanism, a work head and a work head driving mechanism. The buffering mechanism comprises a buffering shell, a buffer and a force sensor. The buffering shell is in sliding connection with a linear feeding shell of the linear driving mechanism and is also in sliding connection with a spindle motor shell of the work head driving mechanism. Both the buffer and the force sensor are installed in the buffering shell. One end of the buffer is connected with one end of the force sensor, and the other end of the buffer is connected with the inner wall of one end of the buffering shell. The other end of the force sensor is connected with one end of the spindle motor shell. The work head is installed in the work head driving mechanism. By connecting the work head to a motion platform, impact can be reduced. By controlling contact force generated in the operation process through buffer type operation, machining quality is improved. Contact force control is achieved completely through buffer type operation, requirements for movement and precision of the connected motion platform are quite low, and then the overall manufacturing cost of the equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a buffer type contact force active control multipurpose operating equipment. Background technique [0002] With the development of automation equipment and robot technology, various coordinate machine tools, machining centers and articulated industrial robots have come out one after another, and gradually formed two types of general motion platforms, coordinate type and articulated type, and the connections at the ends of these two types of motion platforms are different. The job head can complete various job tasks. [0003] However, these two types of general-purpose motion platforms have the following disadvantages when performing secondary processing on already-formed work objects with large errors (such as pipe fittings, sheet metal surfaces, etc.): First, these two types of motion platforms use spatial coordinate data To drive the work head to work, it is nece...

[0003] However, these two types of general-purpose motion platforms have the following disadvantages when performing secondary processing on already-formed work objects with large errors (such as pipe fittings, sheet metal surfaces, etc.): First, these two types of motion platforms use spatial coordinate data To drive the work head to work, it is necessary to know the precise size and spatial position of the work object in advance; secondly, because the work head needs to achieve a precise spatial position, each degree of freedom of these two types of motion platforms is required to have high precision. It may also need to be equipped with reverse engineering equipment, so the cost is high
