Inspection method for taper ring plug gauge

Specification of taper plug gauge: 3mm-300mm

To inspect the inner cone hole, first there should be a taper plug gauge, which is a standard outer circle taper gauge. Apply 2-4 lines of red lead or blue oil evenly on the plug gauge, then insert the plug gauge into the inner cone hole and rotate it 60-120 degrees. Take out the taper plug gauge to see the wiping marks on the surface paint to judge the quality of the inner cone. The more contact area there is, the better the taper. Otherwise, it is not good. Generally, use a standard gauge to inspect the taper contact, which should be at least 75%, Moreover, close to the large end, the coloring method can only be used for inspection of precision machined surfaces.

The taper gauge is used to check the conical angle and diameter of various industrial machinery parts, tools, etc. to ensure interchangeability as a conical part. The taper gauge is mainly used on the spindle and center hole of lathes and cylindrical grinders, the spindle hole of drilling machines, drills, reamer handles, and sleeves; The spindle hole of the 7/24 conical milling machine is used; Jacobs taper is used on drill chucks, and taper gauges can be used to measure the diameter of a cone by drawing lines at the reference position, cutting lines at the reference position, and cutting lines at the boundary. Although this method is not applicable, Morse taper gauges, 7/24 taper gauges, and Brown sharp taper gauges are generally measured by drawing lines at the reference position.

The taper ring gauge is mainly used to inspect the external taper and contact rate of products, and is a specialized comprehensive inspection tool. Due to the simple design and detection of the colored taper ring gauge, it is widely used in workpiece measurement.

The taper gauge standard and function are manufactured according to the JB/T9981-99 standard, used to inspect the geometric precision of various machines and beds. It is made of high-quality carbon tool steel and undergoes multiple heat treatments during processing. The working surface is precisely ground. It is mainly used to inspect the accuracy of industrial cones and various CNC machine tools and precision instruments for checking the taper of spindles and holes. The taper gauge is a key tool in the machining process of machine tool spindles. With the performance and accuracy of machine tools The further improvement of speed has put forward more stringent requirements for the manufacturing of taper gauges, and at the same time, higher dimensional and positional tolerance accuracy requirements have been put forward for the grinding of taper gauges.

Cone gauge inspection: Generally, a standard gauge is used to inspect the cone contact, which should be at least 75% and close to the large end. Various taper smooth plug ring gauges (maximum angle greater than or equal to 30 degrees). The usage method first requires a plug gauge, which is a standard outer cone. Apply 2-4 lines of red lead or blue oil evenly on the plug gauge, then insert the plug gauge into the inner cone hole, rotate it 60-120 degrees to remove the plug gauge, and check the wiping marks on the surface of the plug gauge to determine the quality of the inner cone. The more contact area, the better the taper, otherwise it is not good.
