A tool box fixture for machining piston ring grooves

Abstract

The invention discloses a knife box clamp for machining piston ring grooves. The knife box clamp for machining piston ring grooves comprises a knife box body (1), a side face knife clip (3), a ring groove knife (9) and a ring groove knife clamp. The knife box body (1) is provided with an installing groove (25). The ring groove knife (9) and the ring groove knife clamp are installed in the installing groove (25). The side face knife clip (3) is installed on the side, with the installing groove (25), of the knife box body (1) through side face knife clip installing screws (10). The ring groove knife clamp comprises a knife cushion block A (5), a knife cushion block B (6), side face pressing screws (16), an elastic expanding block (31) and elastic expanding screws (27). The bottom of the installing groove (25) is further provided with an elastic expanding screw installing block (2) through threads. The elastic expanding block (31) is arranged outside the elastic expanding screw installing block (2). The knife box clamp for machining piston ring grooves has the advantages that the knife box clamp can be used for clamping the ring groove knife for machining, and is high in rigidity, convenient to use, good in cooling and the like.

Description

technical field [0001] The invention relates to a machining fixture, in particular to a tool box fixture for machining piston ring grooves. Background technique [0002] The structure of the fine ring groove cutter box under the existing technical conditions is relatively simple, the size of the handle is small, and the overall rigidity is not ideal; there is no axial positioning device for the ring groove cutter during installation, so the installation position cannot be fixed when the ring groove cutter is replaced, and the In the process, the size of the piston ring groove changes greatly after the tool is changed, which is easy to cause process waste. Moreover, the knife box uses screws to press the ring groove knife from the side of the ring groove knife. Since the screw cannot be directly pressed on the ring groove knife, it is necessary to add side pads of different thicknesses on both sides of the ring groove knife. The side pads are usually made of some waste The r...
