Tap fixture for tapping of milling machine

Abstract

The invention relates to a tap fixture for tapping of a milling machine, which belongs to the field of mechanical processing equipment. The tap fixture for tapping of the milling machine is characterized by including a connecting head (23), a positioning pin (24), a sliding sleeve (25), and a chuck (26); the connecting head (23) is assembled and connected with a milling machine head (6); the chuck(26) is assembled and connected with a tap shank (27); and the connecting head (23) and the chuck (26) are assembled and connected through the sliding sleeve (25). The tap fixture for tapping of themilling machine is designed reasonably; after the fixture is connected to the machine head, the concentricity can be ensured, and the slide way can freely move axially; therefore, the feed rate is controllable, and the thread accuracy is ensured; and the selection and design of the diameter of each part realize the function of transmitting torque and protect the tap from breaking.

Description

technical field [0001] The invention relates to a tap clamp for milling machine tapping, which belongs to the field of mechanical processing equipment. Background technique [0002] During the processing of threaded holes on the end surface of large workpieces such as rolls, the angle between the threaded hole and the end surface of large workpieces is required. Due to these relatively high processing requirements and the inability to place the workpiece vertically, it is difficult to use a drilling machine for tapping. Even if it can be used, the accuracy cannot be achieved. skills requirement. It is easier to level the workpiece when using a milling machine for tapping, and it is relatively simple to align the milling machine head and the drilling surface. However, the setting of the feed amount of the milling machine during tapping is complicated and the operation is difficult, especially in the process of processing large workpieces. Tap breakage occurs, increasing proc...
