Flange circumference branch hole scribing device for machining

Abstract

The invention discloses a flange circumference branch hole scribing device for machining, which comprises a base and a top seat; the base and the top seat are both horizontally arranged, the top seatis located right above the base, and the base and the top seat are fixed together through a plurality of support columns which are vertically arranged around the base and the top seat; and an operation table is fixed to the middle of the top face of the base. The flange circumference hole dividing and scribing device for the machining provided by the invention has the beneficial effects that a stud descends to drive a scribing pen of a scribing assembly to press the surface of a flange, and then a lifting plate is rotated to drive the scribing pen to circumferentially rotate to slide out of acircumferential line of a branch hole; then a vertical plate is used to compare markings of an indicating dial to enable the scribing pen to determine hole positions at equal intervals, and the centerposition of the hole positions is determined by staggering circumferential lines by sliding along an adjusting groove, so that a mode that processing personnel directly use tools such as an index ruler to measure and contrast the markings on the flange surface is replaced, and the scribing operation is accurate and the scribing efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical processing auxiliary components, in particular to a flange peripheral hole marking device for mechanical processing. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing method, it can be divided into cutting processing and pressure processing. Flange is a common part in mechanical processing. Flange is also called flange flange or flange. Flange is the connection between shaft and shaft. It is used for the connection between the pipe ends, and it is also useful for the flange on the inlet and outlet of the equipment, which is used for the connection between the two equipment. When the flange is processed, it needs to open holes evenly distributed along the circumference, so it needs The position of each hole is first determined by marking the line, but at present, the proc...

According to the difference in processing method, it can be divided into cutting processing and pressure processing. Flange is a common part in mechanical processing. Flange is also called flange flange or flange. Flange is the connection between shaft and shaft. It is used for the connection between the pipe ends, and it is also useful for the flange on the inlet and outlet of the equipment, which is used for the connection between the two equipment. When the flange is processed, it needs to open holes evenly distributed along the circumference, so it needs The position of each hole is first determined by marking the line, but at present, the processing personnel usually use tools such as a graduated ruler to directly measure and compare the marking on the flange surface when marking the line, and the accuracy of the operation is controlled.
