Miller tool holder with function of conveniently replacing cutter

Abstract

The invention discloses a miller tool holder with a function of conveniently replacing a cutter. The miller tool holder comprises the cutter and a tool holder structure, wherein the cutter is connected with a fixing block arranged in an inner cavity of a tool holder body through a guide frame, under the action of a sliding structure, the cutter is clamped to a clamping structure, and finally, thecutter is fixedly locked through a locking nut. In this way, the cutter replacing speed is increased, manpower and material resources are reduced, and the machining efficiency is improved. The cuttercan be quickly positioned through the guide frame, and the positioning precision is improved; the cutter is subjected to secondary fixing through the locking nut, the situation that the cutter is loosened in use to cause damage to the cutter and the tool holder body is prevented, and the service life of the device is prolonged. Through a pull spring, the distance between an upper L-shaped fixing block and a lower L-shaped fixing block can be adjusted, and the requirements for cutters of different thicknesses can be met; under the action of a third spring, the distance between two fixing framescan be adjusted, the requirements for cutters of different widths can be met, the practicability of the device is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of milling machine devices, in particular to a milling machine tool holder for convenient tool replacement. Background technique [0002] The milling machine is a machine tool with a wide range of uses. It can process planes (horizontal planes, vertical planes), grooves, toothed parts, spiral surfaces and various curved surfaces on the milling machine. In addition, it can also be used to process the surface and inner hole of the rotating body and perform cutting work. When the milling machine is working, the workpiece is installed on the worktable or the accessories such as the indexing head. The main movement of the milling cutter is the rotation, supplemented by the feed movement of the worktable or the milling head, and the workpiece can obtain the required processing surface. Due to the multi-blade intermittent cutting, the productivity of the milling machine is high. Simply put, a milling machine is a...

Problems solved by technology

[0003] The traditional milling machine tool holder that is convenient for tool replacement needs to be unscrewed by a wrench to unscrew the bolts that fix the tool, and then replace it, which is time-consuming and laborious, affecting processing efficiency, and needs to be re-corrected and positioned after each tool change
