Abstract

The invention discloses a fast clamping system. The fast clamping system comprises a pedestal with a hanger, clamp fixing bases and clamps, wherein the clamp fixing bases and the clamps are movably fixed to the hanger. The clamp fixing bases are provided with mounting grooves matched with the corresponding clamps. Each clamp comprises a fastening screw rod with the two ends being provided with threads and dovetail clamping blocks located at the two ends of the fastening screw rod. The dovetail clamping blocks comprise positioning parts which are matched with the mounting grooves in the clamp fixing bases for positioning and clamping parts with dovetail structures. The positioning parts of the dovetail clamping blocks are screwed at the two ends of the corresponding fastening screw rods separately. By adoption of the fast clamping system, the multi-operation, multi-position and multi-part machining requirements can be met, and clamping rigidity is good; moreover, clamping force is evenly distributed, predeformation of parts is reduced and machining precision is improved; and the adaptability is high, the parts and the surfaces of the fixing bases can be tightly attached easily through the clamping blocks, and there is no need for workers to inspect the fitness of the bottom faces of the parts.

Description

technical field [0001] The invention relates to the technical field of fixtures for machining centers in machining and manufacturing, in particular to a quick clamping system. Background technique [0002] After long-term development of mechanical processing technology, many auxiliary technologies have been derived. The fixture used in the processing process is an important factor determining the processing efficiency. It is an auxiliary tool that develops very rapidly. The rapid mold change technology of the fixture is the development of the current fixture. direction. [0003] The current development trend of fixtures mainly has the following characteristics: 1. Standardization. This type of design usually has compatible standard interfaces, standard sizes and even standard fixture forces, etc. Usually, there are many types of optional specifications to adapt to different working conditions; 2. Modularity, the modular design can be combined by the user with the basic comp...
