Problems solved by technology

[0006] The purpose of the present invention is to provide an integrated kinematic pair structure driven by a slider and a telescopic shaft, which can effectively reduce the number of modules of a reconfigurable parallel machine tool, reduce manufacturing costs, and overcome the shortcomings of the original drive methods that cannot be used interchangeably. Through the integrated motion pair structure, two different driving modes can be realized

Embodiment Construction

[0020] The structure and working principle of the integrated kinematic pair driven by the slider and the telescopic shaft of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] figure 1 , figure 2 It is a structural schematic diagram of the present invention: it includes a sleeve 2, two slide blocks 6, two pin shafts 7, a hollow fixed length rod 1 and a linear drive unit. Sleeve 2 is provided with chute 4 along the upper and lower sides of its axial direction. Two sliders are respectively installed in the chute on both sides of the sleeve and can reciprocate along the chute. Make the notch 12 that fixed length bar 1 swings; The hollow fixed-length rod 1 has a groove 11 along its axial rear side and a through groove 10 at the right end, a round through hole 16 on the upper and lower sides of the through groove and a square countersink 15 outside the round through hole. The part of the pin shaft protruding from the ...

Abstract

The present invention relates to movement pair structure design based on motor drive and with integrated functions. The movement pair structure includes one sleeve, one hollow length-fixing rod, two slide blocks, two pinshafts and one linear drive unit comprising nut, screw, motor driving the screw and motor seat. The nut in the slot of the hollow length-fixing rod is fixed to the pinshaft, the screw has one end inserted into the hollow length-fixing rod to form screw pair with the nut and the other end connected to the motor shaft, and the motor is fixed to the sleeve via the seat. The movement pair structure makes it possible to reduce the number of modules in reconstructed parallel machine, lower manufacture cost and realize two different driving modes.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a motor-driven kinematic pair structure design with integrated functions but no redundancy. Background technique [0002] In the field of mechanical manufacturing, in the face of increasingly complex parts processing shapes and special processing requirements, the way that the tool or workpiece of traditional machine tools can only move along the fixed guide rail has great limitations. In order to overcome the common In recent years, a new type of machine tool called parallel machine tool has emerged, which uses a telescopic axis or slider that can be controlled in parallel to drive the fixed-length axis to replace the traditional machine tool. Fixed guide rail system; adopts frame structure, replacing traditional bulky components such as bed and column. [0003] The typical structure of the existing parallel machine tools at home and abroad mainly i...
