Problems solved by technology

[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 The size of the piston ring groove changes greatly after the tool is changed, and it 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 ring groove cutter body is composed of different lengths, the surface quality cannot be controlled, and the installation position cannot be solidified, which makes it very inconvenient to replace the ring groove cutter. Its rigidity is also poor, and it is impossible to control and predict the processing quality after changing the tool; The tool handle does not clamp the upper side of the ring groove cutter, which has a certain impact on the rigidity of the ring groove cutter
At the same time, using the old structure of the tool box, the installation groove structure of the front ring groove cutter is relatively large, and the cooling water outlet hole of the turret can only cool the cutter body from a distance from the side. When processing the ring groove, the ring groove blade is in the piston ring groove , due to the structure of the knife box and the piston ring groove itself, the entry of cooling water is blocked, so that the cooling water cannot directly cool the piston ring groove and the knife tip, nor can it directly wash away the aluminum chips, and can only rely on reflection from the knife box The cooling water cools the tool tip and takes away the aluminum chips, which affects the effect of the cooling water, resulting in poor cooling of the piston ring groove and tool tip, which affects the service life of the ring groove cutter and the processing quality of the piston ring groove

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.
