Problems solved by technology

Due to the lack of necessary flexible auxiliary support in the conventional honing process, the problem of clamping deformation can be eliminated in time. The cutting force applied by the processing tool to the inner wall of the thin-walled part is enough to cause deformation beyond the process requirements, and the deformation of the waist drum is extremely high. hard to repair

Embodiment Construction

[0029] In order to better illustrate the present invention, it will be described in detail below in conjunction with the accompanying drawings.

[0030] see figure 1 , an auxiliary clamping structure to prevent honing deformation of the inner hole of large-diameter thin-walled parts, said structure includes a bottom plate 2, a pressing assembly, an inflatable ring 10, and a placement cylinder 11; Put it on the outer circle of the product and put it into the placement tube 11. The inflation nozzle of the inflatable ring 10 is put into the waist-shaped hole of the placement tube 11, and the pressing assembly is fixedly connected on the placement tube 11. The pressing assembly includes an outer ring 4, an end cover 5, a support ring 6, and a pressure plate 9; the support ring 6 is installed in the end cover 5, and the end cover 5 with the support ring 6 is installed in the counterbore F Among them, the pressure plate 9 is mounted on the outer end surface A of the outer ring 4 an...

Abstract

The invention belongs to the technical field of mechanical manufacturing, and particularly relates to an auxiliary tool for preventing a large-diameter thin-wall part inner hole form deforming duringhoning. The tool comprises a bottom plate (2), a compressing assembly, an inflatable ring (10) and a placing barrel (11). According to the tool, a relatively comprehensive auxiliary supporting structure is used for preventing the large-diameter thin-wall part inner hole from deforming during honing, and a flexible supporting structure and a multi-axial full compressing structure are added; in theusing process, the compensation of the cutting force of a cutter by small allowance is realized through air pressure, and meanwhile, auxiliary supporting is exerted on other thin-wall parts, and the rigidity is increased; deforming during clamping of a thin-wall part caused by rigid auxiliary supporting is also avoided; and meanwhile, the clamping structure is simple, the clamping performance is reliable, the parts are easy to maintain and replace, the practicability of a clamp is improved, and the problems of stress deformation, lack of stress compensation and the like brought by a supportingscheme are overcome.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to an auxiliary tool for preventing honing deformation of the inner hole of a large-diameter thin-walled part. [0002] technical background [0003] In the honing process of the existing large-diameter and thin-walled oil tanks, the processing deformation has not been effectively controlled. In the past, in order to solve the problem of machining deformation, the method of rotating the parts was usually adopted, that is, the parts were clamped on the main shaft, and the boring tool was used to cut with a small allowance to gradually meet the requirements. This kind of processing method is not only extremely inefficient, but also in fine processing, especially in the processing of large-diameter fuel tank inner holes in the through-hole state, the processing error is far greater than the process requirements. Due to the lack of necessary flexible auxilia...
