Master plate clamp of vertical type milling machine

Abstract

The invention belongs to the technical field of mechanical processing fixtures, and in particular relates to a master plate clamp of a vertical type milling machine. The master plate clamp comprises a base and a U-shaped sliding seat movably connected with the base, wherein a fixed plate connected with the U-shaped sliding seat is arranged on the top surface of the base; gears and sliding chutes are arranged on the inner side of the fixed plate; racks matched with the gear are arranged opposite to the bottom surface of the U-shaped sliding seat; bulges matched with the sliding chutes are arranged on the outer walls of vertical plates on two sides of the U-shaped sliding seat; a fastening bolt is also arranged on the vertical plate on one side; threaded holes detachably connected with a master plate are also formed in the top surfaces of the vertical plates on the two sides; limiting nails are arranged on the front side and the rear side of the sliding seat in the sliding direction. When a cutter works, the position of the sliding seat can be locked, so that the cutter and a workpiece cannot generate relative sliding; therefore, the processing precision is improved, and the cutter can be protected from damage.

Description

technical field [0001] The invention belongs to the technical field of machining fixtures, in particular to a template fixture for a vertical milling machine. Background technique [0002] Vertical milling machine has a wide range of applications in mechanical processing. It is used to process various required parts or workpieces. When processing certain curved grooves, it is often necessary to use a template to make the longitudinal direction of the milling machine table The feed is decomposed into the relative lateral motion between the processed workpiece and the tool to achieve the purpose of processing, so a special template and template fixture are needed to achieve it, and the existing template fixture is used when the tool is lowered. It is easy to produce relative sliding between the seats, and the centering of the tool is not accurate, resulting in a decrease in machining accuracy and easy damage to the tool due to shaking.
