Abstract
The utility model discloses an knife clamping and loosing device which comprises a knife rest. A hydraulic cylinder is fixedly installed in the knife rest. A piston rod of the hydraulic cylinder is connected with a movable rod used for an upper pipe clamp. Threads are arranged on the movable rod used for the upper pipe clamp. Two nuts are arranged on the threads in a sleeved mode. A reset clamping device is arranged on the movable rod used for the upper pipe clamp. One end, far from the piston rod, of the movable rod used for the upper pipe clamp extends out of the knife rest, and a wedge-shaped block is installed through screws. The inclined plane of the wedge-shaped block is matched with a knife holder. The other face of the wedge-shaped block contacts with a knife body. The knife holder is fixedly installed on the knife rest. The hydraulic cylinder supplies power to the elastic knife so that central control and operation are convenient. A cutter is clamped through the wedge-shaped block, and clamping is reliable. The two nuts are arranged on the movable rod used for the upper pipe clamp. By rotating of the nuts, the degree of tightness of a belleville spring can be adjusted and a clamping force is indirectly adjusted.
Description
Technical field
The utility model relates to a kind of machining set-up, relates in particular to a kind of degree of tightness knife system.
Background technology
The machine of cutting is a kind of of lathe, and it adopts hydraulic-driven, and security performance is reliable, and is easy to operate.Cutter is applicable to metal recovery processing factory, abandoned car is disassembled field, metallurgy and foundry industry, the shaped steel of various shapes and various metal material are carried out cold conditions cut off, suppress flange, and Powdered goods, plastics, fiberglass, insulating materials, rubber is compressing.
The cutter hub of cutter is usually longer, need to it be connected with tool rest by a plurality of fixtures, traditional cutter cutter hub is bolted on the tool rest, in the needs laid-up, need one by one bolt to be screwed out cutter hub is write, after maintenance is finished, to screw bolt cutter hub is clamped, because the more loading and unloading of clamping bolt are very inconvenient.
