Machine and turntable clamp for four-axis processing center

Abstract

The invention relates to a machine and turntable clamp for a four-axis processing center. The clamp comprises a clamp bottom plate (8), a tail seat (2), a dividing head (9), an oil / gas path distributor component (1), L-shaped plates (4), a bridge plate (7) and clamp location clamping units, wherein the tail seat (2) and the dividing head (9) are fixedly arranged on the clamp bottom plate (8); the oil / gas path distributor component (1) is arranged on the outer side face of the tail seat (2); two L-shaped plates (4) are oppositely arranged and are respectively connected with the tail seat (2) and the dividing head (9) by a transition plate (3); two ends of the bridge plate (7) are respectively connected with the L-shaped plates (4); a plurality of clamp location units are provided and are uniformly spaced and fixed on the bridge plate (7) in sequence. The machine and turntable clamp has the advantages that a modular design and a ball lock location system are used for realizing fast changing the clamp when the type of a production line is changed; hydraulic clamping is used, so that a reliable clamping force is provided; an airtight detection technology and a fast assembling / disassembling limit block are used, so that an error proofing function is available.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a machine-added turntable fixture for a four-axis machining center. Background technique [0002] In the mechanical processing and manufacturing industry, especially in the processing of auto parts, there are often small batch production of multiple varieties. Changeover and debugging take up 40%-50% of the entire line changeover time. Because the existing multi-station fixture adopts the independent replacement design of a single fixture station, each station fixture needs to be adjusted separately for each changeover, so the changeover time usually takes 3-5 days, and the production efficiency is low. The rate is not high. Existing fixtures usually use compressed air as the power source for parts clamping. Compressed air usually uses an air compressor station as the power output source. The air pressure is greatly affected by the environment and the number of compressed air...

Because the existing multi-station fixture adopts the independent replacement design of a single fixture station, each station fixture needs to be adjusted separately for each changeover, so the changeover time usually takes 3-5 days, and the production efficiency is low. rate is not high

Existing fixtures usually use compressed air as the power source for parts clamping. Compressed air usually uses an air compressor station as the power output source. The air pressure is greatly affected by the environment and the number of compressed air terminals used. The input air pressure of the fixture is unstable, resulting in the clamping of the fixture. The force fluctuates, which leads to unstable processing quality of parts. At the same time, due to the recompressibility of air, high speed and high feed cannot be used in the processing process, and the processing efficiency of parts is not high.

General fixtures have no parts clamping and misplacement device and provide fast clamping limit blocks. During the processing process, there are potential threats of clamping errors or improper clamping, resulting in waste products due to incorrect or insufficient clamping of parts.
