Novel sealing bolt for machine tool protective cover and assembly structure of sealing bolt

Abstract

The invention provides a novel sealing bolt for a machine tool protective cover and an assembly structure of the sealing bolt. The bolt comprises sheet metal A and sheet metal B, a through hole is formed in the center of the sheet metal B, a welding nut matched with the through hole is arranged on one side of the sheet metal B, the sheet metal A is arranged on the other side of the sheet metal B, and a kidney-shaped hole connected with the through hole is formed in the sheet metal A. The sealing bolt comprises a bolt rod and a bolt head, a gasket clamping groove is arranged at the large end of the bolt head, one end of the bolt rod is connected to the center of the gasket clamping groove, the other end of the bolt rod sequentially penetrates through the sheet metal A and the sheet metal B and is fixedly meshed with the welding nut, an elastic washer is sleeved with the gasket clamping groove, and the bolt rod on the outer side of the elastic washer is sleeved with a flat washer. According to the scheme, the problem that connection hole liquid on the machine tool protective cover leaks and permeates is effectively solved under the action of the bolt rod, the elastic washer and the flat washer, and meanwhile the problem that connection holes in the machine tool protective cover are not aligned is solved.

Description

technical field [0001] The invention relates to the field of mechanical fastening connectors and seals, in particular to a novel sealing bolt for a machine tool protective cover and an assembly structure thereof. Background technique [0002] In the field of sheet metal manufacturing, welding deformation has always been a common problem. For machine tool shields, welding deformation will cause the connection holes of the various components of the shield to be misaligned. In order to avoid this problem, the technology is usually designed. Changing the connecting round hole into a waist-shaped hole is convenient for the assembly personnel to adjust and adjust, thereby indirectly eliminating errors caused by other manufacturing such as welding deformation. The machine tool spindle rotates at high speed and splashes everywhere, so the processing area of ​​the machine tool is filled with impurities such as liquid, mist gas, and oil. This makes the sealing of the protective cover ...

[0002] In the field of sheet metal manufacturing, welding deformation has always been a common problem. For machine tool shields, welding deformation will cause the connection holes of the various components of the shield to be misaligned. In order to avoid this problem, the technology is usually designed. Changing the connecting round hole into a waist-shaped hole is convenient for the assembly personnel to adjust and adjust, thereby indirectly eliminating errors caused by other manufacturing such as welding deformation. The machine tool spindle rotates at high speed and splashes everywhere, so the processing area of ​​the machine tool is filled with impurities such as liquid, mist gas, and oil, which makes the sealing of the protective cover a rigid functional requirement, and the connection holes on the protective cover often cause liquid leakage
