Problems solved by technology

[0006] However, the tool table is equipped with multiple processing tools and is heavy, so the inertia is also large
Therefore, it cannot adapt to high-speed reciprocating movement

Embodiment Construction

[0023] Below, combine Figure 1 to Figure 3 The first embodiment of the present invention will be described.

[0024] figure 1 It is an explanatory diagram showing the outline of a vertical lathe equipped with the non-circular machining device of the present invention, figure 2 Is a top view of the main part, image 3 It is a cross-sectional view of the main part.

[0025] The overall vertical lathe represented by the symbol 1 has a workpiece head 20, and the workpiece head is figure 1 Move along the horizontal X axis and vertical Z axis on the plane.

[0026] The work head 20 has a work spindle 30, and the work spindle 30 is held by a chuck 32.

[0027] The vertical lathe 1 has a tool head 40, and the tool head 40 has a rotary tool table 42. The rotary tool table 42 rotates along the axis and can be equipped with 12 tools, for example.

[0028] In the case of a circular workpiece, the workpiece head 20 and the tool head 40 that move along the X axis and the Z axis simultaneou...

Abstract

A working device of a noncircular workpiece, such as a piston of an internal combustion engine, is improved. A workpiece (10) is held by a work spindle and rotated. A noncircular working device (100) has a noncircular working unit base (110) and is provided with a servo motor (104). A noncircular working unit (120) is positioned along a Y axis, and an arbitrary cutting tool (133) is selected from a cutting tool group (130). A servo motor (112) reciprocates the noncircular working unit (120) on an X 2 axis in synchronization with the rotation of the work spindle and performs noncircular working of the workpiece (10).

Description

Technical field [0001] The present invention relates to a processing device provided with a tool table suitable for processing non-circular workpieces such as pistons of internal combustion engines. Background technique [0002] Figure 7 Indicating a piston for an internal combustion engine, the piston 10 has a main body 12 made of cast aluminum, and a through hole 13 for inserting a piston pin is formed in the main body 12. Although the head of the piston body 12 is also made of cast aluminum material, the groove portion 14 for setting the piston ring is made of cast iron. That is, the piston 10 is made of different metal materials of cast aluminum and cast iron. [0003] When rotating the outer diameter portion of the piston 10, the workpiece, that is, the piston, is fixed on the workpiece spindle and rotated, and the outer diameter cutting is performed using the turning tool T1. [0004] Since the piston 10 has a non-circular (elliptical) outer diameter shape, non-circular c...
