Abstract

The invention discloses a clamping fixture which comprises a bottom plate, a pair of rotation shaft positioning and mounting plates, a pair of bearings, a rotation shaft, a workpiece clamping and limiting plate, a first toggle clamp mounting plate, a first toggle clamp, a pair of second toggle clamp mounting plates, a pair of second toggle clamps and at least one limiting block. The clamping fixture can effectively simplify working processes and is simple in structure and low in cost. The clamping fixture can process two holes at a certain angle on a general drilling machine and a general tapping machine only through one time of clamping. The invention further discloses a method for drilling and tapping by using the clamping fixture.

Description

technical field [0001] The invention relates to a clamping fixture, in particular to a clamping fixture for drilling / tapping and a use method thereof. Background technique [0002] Due to the complex structure of zinc alloy die-casting workpieces, some features are processed by machining after die-casting, such as drilling, tapping, reaming, and end face milling. To match it, drilling machines, tapping machines, milling machines, and fixtures matching the workpiece are required, and even some features require special equipment to complete the processing. [0003] For example, on a typical car lock bracket, there are two deep threaded holes set at a certain angle to match the bolts. Since the holes have an angle of 58 degrees, they cannot be directly die-cast, so the bottom must be processed by drilling. hole, and then tapped on the bottom hole to form the final threaded hole. Since the general-purpose drilling machine is generally only suitable for drilling in one directio...
