Embodiment 1

[0041] Embodiment 1: The underframe 1 of the processing fixture is fixedly connected to the four-axis bridge plate,

[0042] a. Adjust a pair of positioning pins 9 on a pair of limiting platforms 7 so that the distance they pass through reaches the specified standard;

[0043] B, the positioning sleeve 8 is taken out, and the workpiece is placed, and the vertical hole of the workpiece is inserted into the positioning column 6. At this time, the workpiece falls on the placement platform 71 of one of the four support columns 5 and a pair of limiting platforms 7. At this time A pair of positioning pins 9 on a pair of limiting tables 7 initially limit the workpiece;

[0044] C. The positioning sleeve 8 is inserted into the positioning column 6, and the outer circle of the positioning column is used as the center to adjust the position of the vertical hole so that it is centered, and the centering is adjusted;

[0045] D. After step C is completed, start the pneumatic gripper 3 an...

Abstract

The invention relates to a machining clamp for an aluminum alloy control arm. The machining clamp comprises an underframe (1), a rotary table (2), a pneumatic clamping jaw (3) for locking the rotary table (2), four rotary clamping air cylinders (4), four supporting columns (5), a positioning column (6) and a pair of limiting tables (7). The rotary table (2) is installed on the underframe (1) through a rotary shaft. The pneumatic clamping jaw (3) is detachably installed on the underframe (1), and the rotary table (2) is locked through movement of the pneumatic clamping jaw (3). Pressing blocksare arranged on the rotary clamping air cylinders (4), the four rotary clamping air cylinders (4) and the four supporting columns (5) are all fixedly installed on the rotary table (2), and the pressing blocks of the four rotary clamping air cylinders (4) correspond to the four supporting columns (5) in position. The machining clamp for an aluminum alloy control arm has the advantages that: the tool is light and fast to rotate, and one time rotation does not exceed 15 seconds; the machining size is stable, fully meet the drawing precision requirement, and customers are satisfactory; 16 minutesare needed for machining one workpiece, the production efficiency is high, and the project target is achieved.

Description

technical field [0001] The invention relates to the field of fixture equipment, in particular to a processing fixture for an aluminum alloy control arm. Background technique [0002] At present, the aluminum alloy control arm is an important part of high-end new energy vehicles. The control arm of Weilai Automobile is the same product as the control arm developed and produced by our company for FAW Car. , the precision requirement is high, if the conventional four-axis machining center is used for sub-process processing, the three-time clamping cannot meet the precision requirement, and a relatively large five-axis machining center is required to complete the machining. Contents of the invention [0003] The object of the present invention is to provide a processing fixture for an aluminum alloy control arm to address the above-mentioned shortcomings. [0004] The invention includes a bottom frame, a turntable, a pneumatic gripper for locking the turntable, four rotary cl...
