Drill jig clamp with two-way clamping system

Abstract

The invention relates to a drill jig clamp with a two-way clamping system. The drill is structurally characterized in that a positioning bush is arranged at one end of the upper surface of a bottom board, and a positioning bracket is arranged at the other end of the upper surface of the bottom board; two quickly-disassembled pressure plates are horizontally and symmetrically distributed on the inner end surface of the positioning bush and movably connected with the positioning bush by virtue of screws; the two-way clamping system is arranged on the inner end surface of the positioning bracket, a clamp block is arranged inside the positioning bracket and provided with a through hole, a limit pin is inserted in the through hole and extends out of the positioning bracket, a high-speed rotating guide sleeve is arranged on the upper surface of the positioning bracket, and the inner hole of the high-speed rotating guide sleeve is communicated with the inner cavity of the positioning bracket; and an adjusting and supporting wedge is arranged close to the interior and outer end surface of the positioning bracket, and movably connected with the bottom plate. The clamp is stable and reliable when being used for clamping parts of a certain special structure, is convenient to operate and can be used for shortening the labor period and improving the labor efficiency.

Description

technical field [0001] The invention relates to a drilling jig with a two-way clamping system, which is used in the jig of a machine tool for processing important parts of an important type of aircraft. Background technique [0002] In terms of machine tool fixtures, the variety of workpieces produced in various medium and small batches has accounted for about 85% of the total number of workpieces. Modern production requires that the product varieties manufactured by enterprises are frequently updated to meet market demand and competition. However, general enterprises are still accustomed to using a large number of traditional special fixtures. Generally, in factories with medium production capacity, there are thousands or even nearly ten thousand sets of special fixtures; About 50% to 80% of the special fixtures will be updated in 3 to 4 years, but the actual wear of the fixtures is only about 10% to 20%. Especially in recent years, the application of new processing techn...
