Detailed Description

The machining clamp quick-change standardized structure comprises a standardized base 1, wherein different clamp main bodies 2 are arranged on the standardized base 1; the clamp is characterized in that clamping structures 3 for fixing the clamp main body 2 are arranged on two sides of the standardized base 1, the distance between the two clamping structures 3 is adjustable due to the arrangement of the two clamping structures 3, the height of the upper center and the lower center of the two clamping structures 3 is adjustable, and the left position and the right position of the two clamping structures 3 are adjustable.

Furthermore, the clamping structure 3 comprises two L-shaped fixing plates 4 correspondingly arranged, and a turntable 5 and a lifting table 6 for adjusting the positions of the L-shaped fixing plates 4 are arranged on the outer sides of the L-shaped fixing plates 4.

Furthermore, a fastening hole is formed in one surface, facing the clamp body 2, of the L-shaped fixing plate 4, and the fastening hole is arranged eccentrically.

1) designing a standardized base 1, wherein the standardized base 1 is designed according to different clamp bodies 2, an adjustable clamping structure 3 is arranged on the standardized base 1, and the clamping structure 3 can be adjusted in a plurality of directions according to the different clamp bodies 2;

2) the clamp main body 2 is designed to form a universal module and a special module, the universal module is fixed on the clamping structure 3, and the special module is connected to the universal module through a connecting piece;

further, before the step 1), classifying a plurality of different clamp main bodies 2, collecting the clamp main bodies 2 with similar structures, and designing a universal standardized base' 1 meeting the use requirements of the clamp main bodies 2 through collection.

Further, in the step 2), a plurality of processed products are classified, the processed products with similar structures are collected, a universal module which meets the requirements of the processed products and can be fixed on the clamping structure 3 is designed through collection, a special module which meets the requirements of the processed products and is used by the processed products is designed, and the special module is fixed on the universal module.

The invention will be further explained below for a better understanding of the invention: aiming at the processing clamp of the same type of processing equipment, the invention achieves the purposes of making the distance between the L plates, the height of the rotating center, the size of the fixed thread, the size and the distance between the positioning pins and the height from the center of the rotating table to the center of the main shaft of the processing equipment into the reference seat by standardized making of the types of the large bottom plate, the L plate, the spreader cone, the rotating table and the tail seat, and is arranged on the same type of processing equipment.

The clamp main body part is designed according to relevant standard sizes of the standardized base, so that machining clamps of different products can be quickly installed and fixed through the same positioning pin and fixed thread space, a coordinate system of the product is found, and debugging and production are carried out.
