A compact pneumatic tooling

Abstract

The invention discloses a compact pneumatic fixture, and belongs to the mechanical field. The fixture comprises a fixed bottom plate, a push cylinder fixed seat, a main push cylinder, a clamp retainer, a clamp clamping part, an auxiliary pressing cylinder, a workpiece location block, a main pressing cylinder, a front support block, a rear support block and a workpiece. Due to the mutual cooperation of the clamp clamping part, the front support block and the rear support block, the actual clamping range is expanded, and the actual machining requirements of most of parts can be met; the whole clamp realizes automatic clamping and automatic releasing under the action of the cylinders, so that the reliability of the clamp is improved, and in a working process, the efficiency of placing in theworkpiece and taking out the workpiece is increased; and the whole process is completely pneumatically controlled, so that missing clamping for the workpiece is avoided, and faults in the working process are reduced, and the clamp clamping part and the location block can be adjusted according to the specifications of the workpiece, so that the application range of the clamp is expanded.

Description

technical field [0001] The invention relates to a compact pneumatic tooling, which belongs to the field of machinery, and further belongs to the field of processing center equipment. Background technique [0002] With the continuous deepening of the industrialization process, the fixtures commonly used in CNC machine tools in my country currently include combined fixtures, group fixtures, automated fixtures, and CNC machine tool fixtures. Each fixture has its own characteristics. With the modern manufacturing industry's higher and higher requirements for machining accuracy and processing speed, the fixtures of CNC machine tools are also facing the requirements of upgrading. The focus of the processing industry. [0003] Most of the fixtures used on CNC milling machines or machining centers are general-purpose fixtures, which cannot meet the actual use requirements of large quantities or high precision, and the disassembly of workpieces takes a high proportion of working tim...

[0003] Most of the fixtures used on CNC milling machines or machining centers are general-purpose fixtures, which cannot meet the actual use requirements of large quantities or high precision, and the disassembly of workpieces takes a high proportion of working time

Some factories install multiple general-purpose fixtures within the limited stroke of the machine tool. This method solves the time ratio of disassembling the workpiece to a certain extent, but this method cannot solve the weakness in the tooling debugging stage. Basically, the entire debugging time It is repetitive work, and the interchangeability of universal fixtures and universal fixtures cannot be guaranteed, and the automatic clamping of tooling cannot be realized, and the automatic loosening of tooling cannot be realized. The debugging personnel are in great pain.

Some CNC machine tools use the way of exchanging worktables to realize the disassembly and assembly of workpieces outside the machine. Generally speaking, the cost is huge, and there are inevitable errors in the actual position of the parts after the exchange.
