AI Technical Summary

Technical Problem

Existing CNC machining fixtures for aircraft jigs have a high slider height when clamping large jigs, which is inconvenient to operate and occupies a lot of space, resulting in low practicality of the device.

Method used

The design employs a combination of clamping plates, splicing rods, mounting blocks, double-threaded screws, a second worm gear, a second worm wheel, mounting plates, limit rods, and springs. The spring tension enables the limit rods to position the splicing rods, allowing for rapid adjustment of the clamping plate position. Combined with a first motor, a second motor, gears, a gear ring, and slide rails, the clamping plate's rotation and pitch angles can be adjusted, in conjunction with a CNC machining device.

Benefits of technology

It enables rapid adjustment of the clamping plate position and angle according to the size of the pallet, which facilitates the clamping and processing of large pallets, improves operating efficiency and the practicality of the device.

Abstract

The utility model relates to the technical field of clamping plate machining clamps, and discloses a clamping plate numerical control machining clamp for an airplane jig, which comprises a base, and a clamping device is arranged above the base. According to the clamping plate numerical control machining clamp for the aircraft jig, by arranging the clamping plate, the splicing rod, the mounting blocks, the double-thread screw, a second worm, a second worm gear, a mounting plate, a limiting rod and a spring, the splicing rod is positioned through the limiting rod by means of the tension of the spring, splicing of the splicing rod and the different mounting blocks can be conveniently and rapidly changed, and according to the aircraft jig clamping plates of different sizes, the machining efficiency is improved. The positions of the clamping plates are rapidly adjusted, and a second worm is rotated, so that the clamping plates on the two sides clamp the aircraft fixture clamping plate; by arranging the support, the second motor, the mounting frame, the gear, the gear ring and the sliding rail, the second motor is started, the gear drives the gear ring to rotate, the mounting plate and the aircraft fixture clamping plate can be conveniently controlled to rotate, and the aircraft fixture clamping plate can be conveniently machined in cooperation with a numerical control machining device.
