The precision turning gear ring clamping mechanism has a large washer mounted on the Morse spindle, a spherical roller bearing mounted on the Morse spindle in front of the large washer, a nut mounted on the Morse spindle in front of the spherical roller bearing, a gland mounted on the outer side of the spherical roller bearing, and the gland fixed to the large washer by screws. The precision turning gear ring clamping mechanism of the utility model adopts the floating clamping of the spherical roller bearing, and automatically clamps the workpiece by the tailstock of the machine tool, which is convenient and fast to replace the workpiece, with high processing accuracy and efficiency.
Description
Technical Field
The utility model relates to the technical field of gear machining.
Background
The gear ring is a key part of the automobile rim part. The gear ring is a thin-wall part, and the workpiece is clamped by adopting an end face compacting mode, so that the workpiece is easy to deform during finish turning, and the problems of low machining precision, low production efficiency and the like are caused.
Disclosure of utility model
In order to solve the problem of clamping of a finish turning gear ring, the utility model provides a finish turning gear ring pressing mechanism.
The technical scheme adopted by the utility model for achieving the purpose is that a large washer 3 is sleeved on a Morse mandrel 5 of the finish turning gear ring pressing mechanism, a self-aligning roller bearing 6 is sleeved on the Morse mandrel 5 and positioned at the front side of the large washer 3, a nut 8 is arranged on the Morse mandrel 5 and positioned at the front side of the self-aligning roller bearing 6, a gland 2 is arranged at the outer side of the self-aligning roller bearing 6, and the gland 2 is fixed on the large washer 3 through a screw 4.
A small washer 7 is mounted on the morse axis 5 between the nut 8 and the self-aligning roller bearing 6.
The edge of the gland 2 is provided with a boss 9 which is contacted with the end face of the workpiece 1.
The finish turning gear ring pressing mechanism adopts the self-aligning roller bearing to float and clamp, and utilizes the tailstock of the machine tool to automatically clamp the workpiece, so that the workpiece is convenient and quick to replace, and the machining precision and efficiency are high.

Detailed Description
As shown in figure 1, the finish turning gear ring compressing mechanism of the utility model is characterized in that a large washer 3 is sleeved on a Morse mandrel 5, a self-aligning roller bearing 6 is sleeved on the Morse mandrel 5 and positioned at the front side of the large washer 3, a nut 8 is arranged on the Morse mandrel 5 and positioned at the front side of the self-aligning roller bearing 6, a small washer 7 is arranged between the nut 8 and the self-aligning roller bearing 6, a gland 2 is arranged at the outer side of the self-aligning roller bearing 6, the gland 2 is fixed on the large washer 3 through a screw 4, and a boss 9 which is contacted with the end face of a workpiece 1 is arranged at the edge of the gland 2.
When in use, the large washer 3 is sleeved on the Morse mandrel 5, the self-aligning roller bearing 6 is arranged on the Morse mandrel 5, the small washer 7 is sleeved, the hexagonal nut 8 is screwed down, the gland 2 is sleeved on the outer ring of the self-aligning roller bearing 6, and the gland is fixed on the large washer 3 through the hexagon socket head cap screw. After the pressing mechanism is assembled, the cone shaft of the Morse spindle 5 is inserted into the Morse cone hole of the lathe tailstock.
When the pressing mechanism works, the pressing mechanism is arranged on the lathe tailstock, the workpiece 1 is arranged, the machine tool is started to move the lathe tailstock, the boss 9 at the edge of the pressing cover 2 presses the workpiece 1, the excircle of the workpiece is finely turned, after the workpiece is machined, the machine tool tailstock is moved again, the workpiece 1 is taken down, and the next workpiece can be machined by installing another workpiece.
