Air-pressure type quick-replacement clamp

Abstract

The invention discloses an air-pressure type quick-replacement clamp. The air-pressure type quick-replacement clamp consists of a special clamp (1) for clamping parts, a supporting plate (2), blind rivets (3) and a foundation plate (4), wherein the supporting plate (2) and the special clamp (1) are designed as a whole body; the special clamp (1) comprises a bottom plate and a press plate, which are included by a traditional clamp; the blind rivets (3) comprise positioning blind rivets (5), compensation blind rivets (6) and pure blind rivets (7); one or more positioning blind rivets (5) and one compensation blind rivet (6) are arranged under the bottom plate; MTS chucks (8) which numerically correspond to the blind rivets (3) are integrated on one customized bottom plate, so that the foundation plate (4) is formed; a central hole is formed in the foundation plate (4); each single MTS chuck (8) is positioned by a gapless prism which is provided with an internal ring positioning surface and an external ring positioning surface; a blind rivet hole is formed in each of the MTS chucks (8); and the foundation plate (4) is provided with air channels (9) of an air pressure device, holding frames (10), springs (14) and steel balls (11). Through the adoption of the air-pressure type quick-replacement clamp disclosed by the invention, five sides can be processed in one clamping process; different procedures of the same part or different parts can be processed on one machine tool; the air-pressure type quick-replacement clamp can be clamped on different equipment once for processing; and a part does not need to be demounted during processing, after the part with the clamp is moved onto inspection equipment and inspected, the inspected part can be directly returned onto processing equipment to continue to be processed.

Description

technical field [0001] The invention relates to the processing of shell parts and components in various products, in particular to a pneumatic quick-change fixture. Background technique [0002] Traditional fixtures and processing technology pay attention to single-machine precision and ignore transmission precision; design, process, processing, and inspection standards are not uniform; process conversion depends on fixture positioning, the workpiece leaves the fixture during the conversion, and a set of fixtures is configured for a part of a process; no flexibility, no "Interrupt processing". Take shell parts as an example. [0003] Traditional fixture structure and alignment method (see Figure 1): 1A, bottom plate, 2A, pressure plate 1, 3A, pressure plate 2, 4A, flat plate, 5A, screw, 6A, nut 1, 7A, spring 1, 8A, support 1, 9A, washer, 10A, nut 2, 11A, bolt 1, 12A, cylindrical pin, 13A, diamond pin, 14A, bolt 2, 15A, spring 2, 16A, support 2, 17A, processed parts; it is ...

AI Technical Summary

Problems solved by technology

If the parts need to be sent to the measuring room for inspection during the processing, the parts must be disassembled from the fixture, and the equipment can only be idle during the inspection time of the parts.
