Structure for installing split-style diamond grinding disk

A diamond grinding disk, comprising:

• a plurality of grinding blocks (4), each of said plurality of grinding blocks (4) having a base part (41) and a protruding part (42) extending from said base part (41);
• and
• a base for receiving said plurality of grinding blocks (4), said base comprising a fixing plate (1) having a plurality of L-shaped grooves (8);
• a spring press plate (2) having a second center hole (21);
• a connection plate (3);
• a plurality of springs (6) having an upper end and a lower end opposite to said upper end;
• a plurality of first screws (7), each of said plurality of first screws (7) having a head;
• and a plurality of second screws (9);
• wherein:
• said spring press plate (2) is disposed on said fixing plate (1) through said first plurality of screws (7), and said head is disposed above said spring press plate (2);
• said plurality of springs (6) are sleeved each on one of said first plurality of screws (7), said upper end is fixed to said head, and said lower end is in contact with said spring press plate (2);
• said connection plate (3) is disposed in said second center hole (21), and is connected to said fixing plate (1) through said plurality of second screws (9);
• and
• said protruding parts (42) project through said plurality of L-shaped grooves (8) whereby coupling said plurality of grinding blocks (4) to said base.

A base of a diamond grinding disk for receiving a plurality of grinding blocks, each of the plurality of grinding blocks comprising a base part and a protruding part extending from the base part, the base comprising:

• a fixing plate (1) having a plurality of L-shaped grooves (8);
• a spring press plate (2) having a second center hole (21);
• a connection plate (3);
• a plurality of springs (6), each of said springs (6) having an upper end and a lower end opposite to said upper end;
• a plurality of first screws (7), each of said first screws (7) having a head;
• and
• a plurality of second screws (9);
• wherein:
• said spring press plate (2) is disposed on said fixing plate (1) through said first plurality of screws (7), and said head is disposed above said spring press plate (2);
• said plurality of springs (6) are sleeved each on one of said first plurality of screws (7), said upper end is fixed to said head, and said lower end is in contact with said spring press plate (2);
• and
• said connection plate (3) is disposed in said second center hole (21), and is connected to said fixing plate (1) through said plurality of second screws (9);
• when coupling the plurality of grinding blocks to the base, the protruding parts are inserted into said plurality of L-shaped grooves (8);
• and when uncoupling the plurality of grinding blocks from the base, the protruding parts are removed from said plurality of L-shaped grooves (8).
