Angle-changeable air cylinder side hole machining fixing tool

Abstract

The invention discloses an angle-changeable air cylinder side hole machining fixing tool. The angle-changeable air cylinder side hole machining fixing tool comprises a base and a station installed onthe base. The station comprises a mounting seat which is transversely connected to the interior of a main body supporting block in an inserting mode. A cavity with an opening in the front side is formed in the mounting base. An oil cylinder piston capable of sliding is arranged in the cavity. Two overlapped vertical frames are rotationally mounted on the oil cylinder piston and comprise two long edges and two short edges perpendicular to the long edges. The long edges are connected with a piston oil cylinder. The two short edges extend to the outside of the mounting base, extend in opposite directions, are used for pressing a workpiece, and penetrate through an opening groove. The angle-changeable air cylinder side hole machining fixing tool is moderate in clamping force and firm in fixingand does not damage the workpiece easily. Positioning plates can be replaced on the same tool to be compatible with a plurality of products with different models. Feeding and discharging can be conveniently carried out. The labor is saved. The productivity of an enterprise is improved.

Description

technical field [0001] The invention belongs to the technical field of fixed tooling, and in particular relates to a fixed tooling for machining a side hole of a cylinder at an angle. Background technique [0002] In the compressor cylinder plus production and processing industry, the machine tool is a workpiece clamping tool and a tool power head, so only one part can be clamped and processed at a time. After the processing is completed, the next workpiece can be processed after disassembly, and so on. , slow efficiency, unable to adapt to automated production. [0003] When doing side hole processing, ordinary fixed tooling is manually clamped, and most of the manual clamping is fixed by tightening the bolts and pressing blocks. During the fixing process, the operator’s grasp of the force cannot be completely unified, and the force of tightening the bolts is large.

Problems solved by technology

[0002] In the compressor cylinder plus production and processing industry, the machine tool is a workpiece clamping tool and a tool power head, so only one part can be clamped and processed at a time. After the processing is completed, the next workpiece can be processed after disassembly, and so on. , slow efficiency, unable to adapt to automated production

[0003] When doing side hole processing, ordinary fixed tooling is manually clamped, and most of the manual clamping is fixed by tightening the bolts and pressing blocks. During the fixing process, the operator’s grasp of the force cannot be completely unified, and the force of tightening the bolts is large. Indentation will be left when the bolt is tightened, and the fixation will be unstable when the bolt is tightened, and the workpiece will easily deviate, causing serious consequences; and the manual clamping speed is slow and the productivity is low. When ordinary tooling is clamped, it often has a single position and involves Poor positioning accuracy and poor adjustability for angular changes, especially in mass production, it is difficult to control the size tolerance and shape tolerance of the side hole. Therefore, a clamping tool that can solve the above problems is urgently needed
