Vibration marking method for thin-wall part

Abstract

A vibration marking method for a thin-wall part comprises the following steps that a screw, the thin-wall part, a plug and a nut are connected; the supporting face of the screw is in contact with the plane A, the plane C is in contact with the plane B, the thin-wall part cannot rotate freely under the tightening torque of the nut, and the part is prevented from rotating along with rotation of the screw in the machining process. The outer circle of the plug is tightly matched with the inner hole of the thin-wall part, so that deformation of the outer circle of the part under high-frequency vibration of the vibration pen is avoided. Due to the fact that the outer circle of the plug is tightly matched with the inner hole of the thin-wall part, the problem that the outer circle of the part deforms under high-frequency vibration of a vibration pen is solved; the method is easy to operate, and the requirement for machining personnel is low; machining is stable and reliable, and the product machining quality is improved; and the used auxiliary tool is simple in structure, easy to process and manufacture and low in cost.

Description

Technical Field

[0001] The invention relates to a vibration marking method for thin-wall parts and belongs to the technical field of fasteners. Background Art

[0002] Unless there are special design requirements, thin-walled parts are generally not marked by vibration. During the vibration marking process, the outer circle of the marked part is easily deformed due to the high-frequency vibration of the vibration pen. Summary of the invention

[0003] The invention aims to solve the technical problem that the outer circle of the marked part is very likely to be deformed due to the high-frequency vibration of the vibration pen during the vibration marking process.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A vibration marking method for thin-walled parts comprises the following steps: Step 1: Install the thin-walled part into the screw, and the screw support surface contacts plane A; Step 2: Install a plug at the open end of the thin-walled part to make plane C and plane B contact. Under the tightening torque of the nut, the thin-walled part cannot rotate freely in the axial and longitudinal directions to prevent the part from rotating with the screw during processing; Step 3: Tightly fit the outer circle of the plug and the inner hole of the thin-walled part to avoid deformation of the outer circle of the thin-walled part under the high-frequency vibration of the vibration pen.

[0005] The beneficial effects of adopting the above technical solution are: The invention tightly fits the outer circle of the plug with the inner hole of the thin-walled part, thereby avoiding the problem of deformation of the outer circle of the part under the high-frequency vibration of the vibration pen; the invention is simple to operate and has low requirements on processing personnel; the processing is stable and reliable, and the product processing quality is improved; the auxiliary tooling used has a simple structure, is easy to process and manufacture, and has low cost.

[0009] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0010] A vibration marking method for thin-walled parts comprises the following steps: Step 1: Install the thin-walled part 2 into the screw 1, and the support surface of the screw 1 contacts the plane A5; Step 2: Install the plug 3 at the open end of the thin-walled part 2, so that the plane C7 and the plane B6 are in contact, and the thin-walled part 2 cannot rotate freely in the axial direction and longitudinal direction under the tightening torque of the nut 4, so as to avoid the part rotating with the screw during processing; Step 3: The outer circle of the plug 3 and the inner hole of the thin-walled part 2 are tightly matched, so that when vibrating the marking, the outer circle of the thin-walled part 2 can be prevented from being deformed under the high-frequency vibration of the vibration pen.

[0011] The invention is simple to operate and has high processing efficiency. During the processing, the auxiliary tooling fixes the thin-walled parts horizontally and vertically to avoid shaking of the products during the processing, thereby improving the processing quality of the products.
