Problems solved by technology

[0003] The traditional clamping method makes the positioning accuracy of the clamped parts low, and the position of the rotating body needs to be changed frequently during the measurement or processing process. The process requires manual disassembly of the clamp and re-marking and positioning. This operation process makes the processing efficiency extremely high. Low
This processing method makes the processing accuracy low and the consistency is poor

Abstract

The invention discloses a coaxial assembly and measuring device for a rotary part, which comprises a machine base, two positioning and moving devices, a measuring device and a control system. The two positioning and moving devices are installed on the base platform, and the measuring device is installed on the base platform. The invention can position and clamp the thin-walled rotary parts, and carry out coaxial assembly, and can measure the radial runout of each section of the workpiece through the positioning and moving device and the measuring device, and the positioning accuracy of the workpiece is high, which can effectively Improve assembly measurement accuracy and efficiency. The invention adopts the structural form of the floating positioning head, and the upper edge of the positioning head and the positioning plate has rounded corners, which can simultaneously perform good contact positioning with the contour surface of the conical rotary body, and the positioning accuracy is high, and the workpiece is clamped by vacuum adsorption. , so that the force on the workpiece is uniform and controllable. The positioning and moving device can be lifted and rotated as a whole to realize the coaxial assembly of two workpieces and improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of positioning, clamping, assembly and measurement of rotary parts, in particular to a coaxial assembly of conical thin-walled rotary bodies and cylindrical thin-walled rotary bodies and radial runout measurement technology for multiple sections of workpieces . Background technique [0002] Nowadays, thin-walled rotary parts are widely used in the field of machinery manufacturing, especially the parts used in aerospace vehicles. Their material properties have high hardness, low elastic modulus, poor plasticity and toughness, and good heat resistance. The characteristics of the tapered and thin-walled shape make the part strong in the axial direction and easy to deform when clamped in the radial direction. It is a typical workpiece that is difficult to position, clamp and process. [0003] The traditional clamping method makes the positioning accuracy of the clamped parts low, and the position of the rotatin...
