Embodiment Construction

[0016] The invention uses a dial indicator to accurately correct the inclination angle of the end milling head of the milling machine. This embodiment takes the processing of precision inclined planes or oblique holes as an example. First of all, do the preparatory work, set the deflection angle of the end milling head 3 as α according to the inclined surface or inclined hole of the workpiece to be processed, and then deflect the end milling head 3 of the milling machine corresponding to the set angle α, and set the actual deflection angle as α ', then fix the dial indicator 4 on the workbench 2 of the milling machine through the magnetic gauge base 5, and shake the feed mechanism of the milling machine workbench 2 so that the contact of the dial indicator 4 presses against the outer wall of the end milling head 3 , and take this point as the starting point A. After the preparation work is completed, shake the horizontal feed mechanism 1 of the worktable 2 to move the dial in...

Abstract

The invention discloses a method for accurately calibrating the inclination of a vertical milling head of a milling machine by using a dialgauge. In the method, after the vertical milling head deviates an angle according to an inclined plane or inclined hole of a workpiece to be machined, the dialgauge is fixed on a workbench, a horizontal distance and a vertical distance between two points on the outer wall of a part, which is arranged on the vertical milling head and coaxially extends with the vertical milling head, and has an outer surface parallel to the axis of the vertical milling head,are measured by the dialgauge, the data obtained through measurement is calculated, the deviation between the actual deflection angle and the set deflection angle of the vertical milling head is compared, and the vertical milling head is regulated to a right place according to the deviation. By the method, the inclination of the vertical milling head of the milling machine can be accurately calibrated, the production period of the product is shortened, the production cost is reduced, and the method has high promotion and application value.

Description

technical field [0001] The invention relates to a method for accurately correcting the inclination angle of the end milling head of a milling machine by using a dial indicator. Background technique [0002] When machining precision bevels or oblique holes on milling machines, special fixtures are generally required. Due to the high manufacturing cost and troublesome installation of special fixtures, this method is usually used in mass production. In single-piece or small-batch trial production, the use of special fixtures will increase the processing cost of the workpiece, and manufacturing fixtures also requires special time, resulting in extended processing cycles and delays in trial production tasks. Contents of the invention [0003] The task of the present invention is to provide a method for accurately correcting the inclination angle of the end milling head of a milling machine by using a dial indicator during single-piece or small batch production, so as to...
