A Tool Setting Device for Milling Keyway

Abstract

The invention discloses a tool setting device for milling a key groove. The tool setting device comprises a vertical plate fixed below a milling cutter of a milling machine; the end face of one side of the vertical plate is in swinging connection with a pendulum plate, a V-shaped groove is formed in the bottom of the pendulum plate, the top of the pendulum plate is in swinging connection with thevertical plate through a swinging shaft, and the axis of the swinging shaft is located on the straight line where the angle bisector of the V-shaped groove is located at; and a baseline structure is arranged on the vertical plate, a tool setting line structure corresponding to the baseline structure is arranged at the top of the pendulum plate, the baseline structure is located on the straight line where the angle bisector of the V-shaped groove is located at, and the tool setting line structure is located in a plane composed by the axis of the swinging shaft and the angle bisector of the V-shaped groove. The tool setting device for milling the key groove is simple in structure, convenient to operate in tool setting, and high in tool setting precision, and improves the production efficiency, and is also easy to use and popularize.

Description

technical field [0001] The invention relates to the technical field of milling tool setting, in particular to a tool setting device for milling key grooves. Background technique [0002] The key connection is to realize the circumferential fixation between the shaft and the parts on the shaft (such as gears, pulleys, etc.), and to transmit motion and torque. Due to its reliable operation and standardized keys, it has been widely used. The keyway is often processed by milling. Due to the high symmetry requirements of the keyway, tool setting is very important during milling. The existing technology has low precision of tool setting, cumbersome operation, low production efficiency, and cannot guarantee the symmetry requirement of the keyway. Especially for workpieces with arc-shaped processing surfaces, such as cylindrical workpieces, fan-shaped interface workpieces, etc. [0003] For example, the Chinese patent with the publication number CN202845904A and the Chinese patent...

Problems solved by technology

[0003] For example, the Chinese patent with the publication number CN202845904A and the Chinese patent with the publication number CN201109048Y respectively disclose a tool setting device for milling cutters. Therefore, it is necessary to adjust the tool setting device to the corresponding position accurately to ensure the complete fit between the workpiece and the tool setting device, and the tool setting can only be performed after the tool setting device is attached to the workpiece, so the operation of the tool setting The process is cumbersome and requires multiple up and down movements and rotations of the tool setting device, as well as horizontal adjustment of the workpiece by moving the workpiece clamping platform. Due to line of sight errors, the fit between the workpiece and the tool setting device can only be roughly guaranteed To a certain extent, the accuracy of tool setting is not easy to control, and the tool setting time is longer, which affects the production efficiency; moreover, the above tool setting device is directly connected with the fixture of the milling cutter. After the tool setting is completed, the milling cutter needs to be installed. Not only the operation It is cumbersome, and the reinstallation of the milling cutter will cause installation errors with the previous tool setting device, resulting in inaccurate tool setting and poor tool setting effect
