Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a main shaft hanging tool. Background Art

[0002] The spindle refers to the shaft that receives power from the engine or electric frame and transmits it to other parts. It has been widely used in the field of CNC machine tools in recent years. The spindle is usually composed of a spindle body and a nose end. A screw hole is provided at the nose end for disassembling and installing various workpieces. The spindle needs to be hoisted in some processing processes. Usually, the commonly used hoisting method in the workshop is to fix the spindle body with a lifting ring, and then use a hook to hoist the lifting ring, so as to achieve the purpose of hoisting the spindle. However, the above scheme has certain defects. Since the lifting ring cannot directly fix the nose end, the lifting ring located on the spindle body is lower than the screw hole at the nose end. When the lifting ring is used for hoisting, it will interfere with the disassembly and installation of the workpiece at the screw hole. How to invent a spindle hanging tooling, use a balanced hanger, make the position of the hook higher than the spindle, and avoid interference events during disassembly and installation has become a problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0003] In order to remedy the above deficiencies, the present invention provides a main shaft hanging tool, which aims to improve the problem that the position of the hook is lower than the main shaft, which is prone to interference during disassembly and installation.

[0004] The present invention is achieved in that:

[0005] A main shaft lifting tool is used for lifting a main shaft body and comprises a lifting mechanism.

[0006] The lifting mechanism includes a lifting ear, a lifting ring and a fixing bolt. The lifting ear is slidably connected to the lifting ring. The lifting ear is provided with a lifting hole. The lifting spindle body is provided with a spindle and a nose end. A screw hole is provided on the top of the nose end. The lifting hole is positioned higher than the screw hole. The lifting ring is provided with a slide groove, a first mounting hole and a second mounting hole. The second mounting hole vertically penetrates the lifting ring. The lifting ring is fixedly connected to the spindle through the second mounting hole. The fixing bolt thread penetrates the lifting ear, and the fixing bolt is slidably connected to the slide groove.

[0007] In an embodiment of the present invention, a plurality of groups of the first mounting holes are provided, and the plurality of groups of the first mounting holes are arranged in a circular array along the inner wall of the slide groove.

[0008] In one embodiment of the present invention, the slide groove is provided with balls, and the balls are arranged in a circular array along the bottom and top of the slide groove.

[0009] In an embodiment of the present invention, the lifting hole is provided with a first rubber pad, and the first rubber pad is fixedly installed on the lifting hole.

[0010] In an embodiment of the present invention, a plurality of groups of the second mounting holes are provided, and the plurality of groups of the second mounting holes are arranged along the annular array of the suspension rings.

[0011] In one embodiment of the present invention, the lifting ear is configured to be in an arc shape, and the curvature is consistent with the curvature of the outer ring of the lifting ring.

[0012] In an embodiment of the present invention, the lifting ring is provided with a second rubber pad, and the second rubber pad is fixedly installed on the bottom of the lifting ring.

[0013] The beneficial effects of the present invention are as follows: the present invention obtains a spindle lifting tooling through the above-mentioned design. When in use, the lifting ring is installed on the top of the spindle, and the two lifting rings are symmetrically arranged around the nose end. The fixing bolt is unscrewed from the first mounting hole, and the rotating lifting ear drives the fixing bolt to rotate in the slide groove to the processing station, and the fixing bolt is tightened into the first mounting hole. The position of the lifting ear is fixed, and the hook is installed to the lifting hole. The lifting of the spindle is completed, and a balanced lifting device is formed by using the two lifting ears. The position of the hook is higher than the spindle, which effectively avoids interference events during disassembly and installation. At the same time, the lifting station can be replaced without dismantling the lifting to meet the processing of workpieces at more stations. BRIEF DESCRIPTION OF THE DRAWINGS
