Inner circle cutting power head with hydraulic adjusting device

Abstract

The invention relates to an inner circle cutting power head with a hydraulic adjusting device, belongs to the technical field of cutting power heads, and solves the technical problems that in a cutting process, a blade deforms due to friction, vibration and other factors, the cutting effect is influenced, and more belt pulley transmission structures exist. A solution is as follows: the inner circle cutting power head with the hydraulic adjusting device comprises a first hydraulic adjusting device, a driving motor, a second hydraulic adjusting device and a cutter head device which are sequentially arranged from left to right, and the first hydraulic adjusting device comprises a first cylinder barrel, a first piston, an adjusting sleeve and a pressure gauge; the second hydraulic adjusting device comprises a motor connecting flange, a bearing outer sleeve, a bearing check ring, a plurality of bearings, a second cylinder barrel and a second piston. The cutterhead device comprises a cutterhead flange, a fixed cutterhead, a movable cutterhead, an inner circle cutting blade and an annular pressing plate. It is convenient to observe, the working state of the inner circle cutting blade can be rapidly adjusted, the cutting efficiency and quality are not affected, and the structure is saved through the arrangement of the driving motor.

Description

technical field

[0001] The invention belongs to the technical field of cutting power heads, and in particular relates to an inner circle cutting power head with a hydraulic adjustment device. Background technique

[0002] The inner circle cutting blade is a kind of cutting tool. Its thickness is ultra-thin. Through rapid rotation, the inner circle can quickly cut the workpiece to be cut. It has the advantages of small kerf, small cutting flatness and high grinding efficiency. The inner circle cutting blade is bolted to the fixing device through a circle of connecting bolt holes around it. Since the inner circle cutting blade is very thin, only stretching and straightening can have a better cutting effect.

[0003] In the actual work process, there are two problems:

[0004] 1. The blade needs to be pre-tensioned after installation and before cutting. During cutting, the blade will be deformed due to friction, vibration, force, heat and other factors, which will greatly affe...
