Embodiment Construction

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Please refer to figure 1 , figure 1 Structural intent of the device for processing threaded holes on the peripheral surface of the cylinder head provided by the embodiment of the present invention.

[0025] In the indexing method for processing threaded holes on the circumferential surface of the head of the drying cylinder provided by the embodiment of the present invention, the drying cylinder 4 is mounted on the machine tool, the pulse encoder 2 is placed on the main shaft 1 of the machine tool, and the pulse encoder 2 The total number of pulses corresponds to the 360° rotation of the main shaft and is equally divided. One pulse corresponds to an evenly divided circumferential angle. During processing, the drying cylinder...

Abstract

The invention discloses a drying cylinder seal head circumference face threaded hole machining indexing method. A drying cylinder is arranged and clamped on a machine tool, a pulse encoder is placed on a spindle of the machine tool, and the pulse sum of the pulse encoder is evenly divided corresponding to 360-degree rotation of the spindle. One pulse corresponds to one evenly-divided circumferenceangle. During machining, the drying cylinder and the spindle synchronously rotate. A signal conversion device is used for converting pulse signals of the pulse encoder into angle signals. After a control device conducts indexing on a circumference face threaded hole in a drying cylinder seal head according to the angle signals, and the circumference face threaded hole in the drying cylinder sealhead is obtained through machining. Since the pulse encoder is adopted, the drying cylinder can be arranged and clamped on the machine tool, the pulse encoder is placed on the spindle of the machine tool, the pulse encoder is adopted for angle measurement, and therefore accurate indexing of machining of the circumference face threaded hole in the drying cylinder seal head can be achieved under thesituation that workpieces are large. The invention further discloses a drying cylinder seal head circumference face threaded hole machining device.

Description

technical field [0001] The invention relates to the technical field of threaded hole processing, in particular to an indexing method and a processing device for processing threaded holes on a peripheral surface of a head of a drying cylinder. Background technique [0002] The drying cylinder is a pressure vessel with a pressure of 0.8-1MPa. It is the most important part of the drying section of the tissue machine, and its function is to dry the paper. [0003] The diameter of the steel drying cylinder of the high-speed toilet paper machine is relatively large φ3000-φ4880mm, and the threaded holes (holes) on the side of the cylinder head are M42 (φ45 holes) threads evenly distributed around the circle. The center distance of the threaded holes is φ1150-φ2300mm, and the circumference is uniformly distributed 30 - 50 threaded holes (light holes). [0004] The shaft of the drying cylinder and the head of the drying cylinder are fixed with bolts. The threaded holes (holes) of th...
