Embodiment 1

[0034] This embodiment provides a piston boring and milling skirt bottom combined machine tool, such as figure 1 As shown, including protective cover 4, piston positioning tool 3, milling mechanism 11, boring mechanism, manipulator 1, piston positioning tooling 3, milling mechanism 11 and boring mechanism are arranged in protective cover 4, and manipulator 1 is located in protective cover 4 outside.

[0035] Further, the protective cover 4 has a movable door, and by opening the movable door, the manipulator 1 realizes loading and unloading of the piston. The protective cover 4 of this embodiment is made of sheet metal, which can protect the machine tool and prevent personnel from being injured during machining. A numerical control operation unit 6 is installed on the outer side of the protective cover 4, and the numerical control operation unit 6 is composed of a display screen and operation buttons, which can realize man-machine dialogue.

[0036] The manipulator 1 includes...

Embodiment 2

[0048] This embodiment provides a process for machining pistons with a piston boring and milling skirt bottom combined machine tool, including:

[0049]When the piston is clamped, the moving door is in the open state, and the manipulator 1 places the piston to be processed on the piston positioning tool 3. After the piston is clamped and positioned, the manipulator 1 is released and the moving door is closed.

[0050] The position of the piston positioning tool 3 with the piston 14 clamped is adjusted through the Y-axis moving mechanism 12, and the two boring mechanisms are radially aligned with the piston 14.

[0051] The boring mechanism is moved along the X axis by the worktable moving mechanism, the two boring mechanisms are started, and the pin holes on both sides of the piston 14 are processed at the same time; after the boring is completed, the worktable moving mechanism moves in the opposite direction to make the boring mechanism withdraw from the pin hole.

Abstract

The invention discloses a piston boring and skirt bottom milling combined machine tool and process, and belongs to the technical field of piston machining. According to the technical scheme, the piston boring and skirt bottom milling combined machine tool comprises a piston positioning tool, a face milling mechanism and boring mechanisms, and the face milling mechanism is arranged above the piston positioning tool and can move along a Z axis; the boring mechanisms are symmetrically installed on the two sides of the piston positioning tool, and workbench coordinate mechanisms capable of enabling the boring mechanisms to move along the X axis are installed at the bottoms of the two boring mechanisms so that pin holes in the two sides of a piston can be machined at the same time. According to the piston boring and skirt bottom milling combined machine tool and process, the piston is clamped at a time through the piston positioning tool, and the pin holes in the two sides are machined at the same time; and milling of a piston skirt bottom can be achieved, and the machining quality and the machining efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of piston processing, in particular to a piston boring and skirt bottom combined machine tool and process. Background technique [0002] The pin hole of the piston is a high-incidence area for piston failure, and the processing quality and reliability of the piston pin hole are related to the performance of the entire engine. Under the existing technical conditions, the processing method of the steel piston pin hole is usually: firstly process the steel piston skirt bottom with an ordinary milling machine, so as to obtain the processing datum surface, and then use manual feeding on an ordinary CNC boring machine, with Fixtures for boring. There are problems such as low efficiency and low processing precision. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a combined piston boring and milling skirt bottom machine tool and p...
