Problems solved by technology

[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

Abstract

A buffering type contact-force active-control multipurpose operation mechanism comprises a linear driving mechanism, a buffering mechanism and a working head. The buffering mechanism comprises an upper mounting seat, two sliding rods, a sliding rail tail seat, a sliding rail head seat, a force sensor and a buffer. The upper mounting seat is fixedly arranged on a sliding table of the linear driving mechanism. The two sliding rods both penetrate through the upper mounting seat, one ends of the two sliding rods are fixedly arranged on the sliding rail tail seat, and the other ends of the two sliding rods are fixedly arranged on the sliding rail head seat. One end of the buffer is connected with the sliding rail head seat, and the other end of the buffer is connected with the force sensor which is arranged on the upper mounting seat or the sliding table of the linear driving mechanism. The working head is arranged on the sliding rail head seat. According to the buffering type contact-force active-control multipurpose operation mechanism, the working head is transferred to a moving platform so that the impact action can be reduced; the contact force in the operation process is controlled through the buffering type operation, and accordingly the machining quality is improved; due to the fact that the contact force is controlled completely through the buffering type operation, the requirements for movement and accuracy of the transferred platform are lower, and the overall manufacturing cost of equipment is lowered.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a cushioning contact force active control multipurpose operating mechanism. 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 neces...
