Problems solved by technology

However, in the production process, many disk and shaft parts need to be processed by surface adjustment, and the concentricity after processing cannot be guaranteed, and the existing CNC lathe can only process one surface at a time, so it cannot meet high-demand parts. or to lower the standard use
This processing restriction has greatly restricted the development of CNC machine tools and has become a technical problem to be solved urgently.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing.

[0013] as attached Figure 1-2 As shown, a double-end double-piston spindle for a machine tool of the present invention is composed of a spindle main body 1, a bearing, a gland 2, a spindle 3, a belt 4, an oil cylinder 5 and a fixture 6, and the spindle 3 is rotatably connected to the In the main shaft body 1, the belt 4 is connected to the main shaft to drive the main shaft 3 and the clamped workpiece 7 to rotate. The outside of the bearing is fixed by the gland 2. At the end, the jig 6 is driven by the oil cylinder 5, wherein the gland 2, the bearing, the oil cylinder 5 and the jig 6 are all arranged in pairs and arranged substantially symmetrically along the longitudinal centerline of the main shaft body 1. The clamp 6 may be a chuck or collet.

[0014] The invention relates to a double-end surface double-piston main shaft for a machine tool, which can complete the pro...

Abstract

The invention discloses a double-end-face double-piston spindle for a machine tool. The spindle comprises a spindle main body, bearings, glands, a spindle, a belt, oil cylinders and fixtures, wherein the spindle is rotationally connected to the interior of the spindle main body through the bearings; the belt is connected with the spindle to drive the spindle and a clamped workpiece to rotate; the outer sides of the bearings are fixed by the glands; the fixtures for clamping the workpiece are arranged at two ends in a spindle hole; the fixtures are driven by the oil cylinders; the glands, the bearings, the oil cylinders and the fixtures are arranged in pairs and basically and symmetrically arranged along the longitudinal center line of the spindle main body. The spindle fixtures for the machine tool can be simply and effectively configured in the structure to allow the two end faces of the workpiece to be processed at the same time by clamping for one time, so as to meet the concentric and coaxial requirements.

Description

technical field [0001] The invention relates to a double-end surface double-piston spindle for machine tools, in particular to a rotatable spindle clamp that is applied to numerical control to realize simultaneous processing from both end surfaces of a workpiece in one clamping, and belongs to the technical field of mechanical processing machinery manufacturing. Background technique [0002] With the rapid development of CNC machine tools, various machine tool manufacturers have launched their own CNC machine tool products. At present, CNC machine tool processing technology has become the main production method for some high-efficiency and high-precision machining. However, in the production process, many disk and shaft parts need to be processed by surface adjustment, and the concentricity after processing cannot be guaranteed, and the existing CNC lathe can only process one surface at a time, so it cannot meet high-demand parts. Or lower the standard use. This kind of pro...
