Description HOBBING SPINDLE FOR PLANETARY GEARS Technical Field of the Invention
The present invention relates to a hobbing spindle for a planetary gear. Background of the Invention
At present, during machining a planetary gear, a planetary gear blank is sheathed on a spindle of a machine tool, then the gear not machined is locked by a nut at the tail of the spindle, and an operator operates a gear hobbing machine to perform gear hobbing. During the gear hobbing operation, the operators need to rotate the nut upward and downward by hands to axially fix the gear, so it is very time-consuming and the working intensity of the operators will be increased greatly. Moreover, only one gear can be clamped on the existing spindle, so that the gear machining efficiency is low.
Summary of the Invention
An objective of the present invention is to provide a hobbing spindle for a planetary gear, which can clamp a plurality of gears for machining and can greatly reduce the working intensity of operators and improve the gear machining efficiency.
To realize this purpose, the present invention employs the following technical solution. A hobbing spindle for a planetary gear is provided, including a spindle body, wherein a machine tool connection section, a workpiece mounting section and a limiting section are successively provided on the spindle body; the diameter of the machine tool connection section is less than that of the workpiece mounting section, and the diameter of the workpiece mounting section is less than that o the limiting section; workpieces are in transition fit onto the workpiece mounting section; a machine tool spring clamp 1 2016101624 14 Sep 2016 may be connected and fixed on the machine tool connection section; one end of the machine tool spring clamp close to the workpiece mounting section can be resisted against the workpiece mounting section and a workpiece on the workpiece mounting section; and, at least two workpieces can be sheathed on the workpiece mounting section, and the workpiece away from the machine tool connection section is resisted against the limiting section.
In the present invention, the axial fixing of a workpiece is realized by resisting the machine tool spring clamp and the limiting section of the spindle body against two sides of the workpiece, and thus an operator does not need to rotate the nut upward and downward by hands, so that the working intensity of the operators is greatly reduced. The operator may mount workpieces on the workpiece mounting section of the spindle body in advance, then accomplish the mounting of workpieces of a plurality of spindles, and mechanically insert the spindle body into the machine tool spring clamp of the machine tool, so that the hobbing operations on a plurality of machines may be realized by one person. Moreover, as a plurality of workpieces may be mounted on the spindle of the present invention, the gear machining efficiency may be improved.
The present invention may clamp a plurality of gears for machining, and can greatly reduce the working intensity of operators and improve the gear machining efficiency.

Detailed Description of the Invention
As shown in Fig. 1, a hobbing spindle for a planetary gear of the present invention includes a spindle body 1. A machine tool connection section 2, a 2 2016101624 14 Sep 2016 workpiece mounting section 3 and a limiting section 4 are successively provided on the spindle body 1. The diameter of the machine tool connection section 2 is less than that of the workpiece mounting section 3, and the diameter of the workpiece mounting section 3 is less than that of the limiting section 4.
As shown in Fig. 2, three workpieces 5 are in transition fit onto the workpiece mounting section 3, and a workpiece furthest away from the machine tool connection section 2 is resisted against the limiting section 4. A machine tool spring clamp 6 is connected and fixed on the machine tool connection section 2. One end of the machine tool spring clamp 6 close to the workpiece mounting section 3 is resisted against the workpiece mounting section 3 and the workpiece on the workpiece mounting section 3 furthest away from the limiting section.
As shown in Fig. 3, a positioning hole is provided on one side of the workpiece mounting section 3 of the spindle body 1 close to the machine tool connection section, a steel ball 7 is provided within the positioning hole, and a portion of the ball body of the steel ball 7 is protruded from the positioning hole and is resisted against the workpiece on the workpiece mounting section furthest away from the machine tool connection section 2.
As shown in Fig. 2 and Fig. 3, a cavity having an opening facing the limiting section 4 is provided within the spindle body 1. The cavity extends into the workpiece mounting section 3, and the positioning hole is communicated with the cavity. A conical body 8 having an angle of 30° is provided within the cavity. A cone head at the front end of the conical body 8 is resisted against the steel ball 1, and the conical body 8 moves forward and backward within the cavity so as to move the steel ball up and down within the positioning hole. A bolt 9 is provided at the real end of the conical body 8, and a spring 10 is provided between the bolt 9 and the conical body 8, so that the cone head in front of the bolt may be displaced by applying a force to the rear end of the bolt. A groove matched with the cone head of the conical body is provided at a 3 2016101624 14 Sep 2016 deepest position of the cavity, the bolt 9 is completely located within the cavity, and a conical groove is provided at the rear end of the bolt 9, so that the bolt drives the cone head to displace by applying a force to the bolt by the tip.
When in use, workpieces 5 are sheathed onto the workpiece mounting section 3 and resisted against the limiting section 4. Then, the spindle body 1 is inserted into the machine tool spring clamp 6 of the gear hobbing machine tool, and the workpices are axially fixed by the machine tool spring clamp 6 and the limiting section 4. The workpieces are in transition fit onto the workpiece mounting section, and a workpiece furthest away from the limiting section is resisted against the steel ball 7 of the spindle body, so that the steel ball 7 applies an elastic force to the workpiece so as to fix the workpiece in the circumferential direction.The gear hobbing machine tool is started for workpiece hobbing, after the workpieces are fixed. 4
