Embodiment 1

[0031] see figure 2 , image 3 , this embodiment provides a large modulus gear tooth surface polishing equipment, including a CNC gear milling machine tool, a pneumatic control mechanism 2 is installed on one side of the milling cutter shaft 3 of the CNC gear milling machine tool 1, and the pneumatic control mechanism 2 The control mechanism 2 includes a pneumatic tool 21 that can rotate at high speed. The end of the pneumatic tool 21 is provided with a pneumatic grinding head 22 that can be linked with the workpiece shaft and move along the involute of the tooth surface of the workpiece to polish the workpiece.

[0032] The pneumatic tool 21 described in this embodiment is connected to the CNC gear milling machine tool 1 through a fixed base 23 . The fixed base 23 is connected with the CNC gear milling machine tool 1 through a telescopic cylinder. When the equipment is performing whirlwind chamfering, the telescopic cylinder remains in the retracted state to avoid interfer...

Embodiment 2

[0039] This embodiment provides a polishing process of the large-module gear tooth surface polishing equipment described in the embodiment. When the workpiece is chamfered, the pneumatic grinding head 22 is started synchronously to perform the polishing process.

[0040]The polishing process of the pneumatic grinding head described in this embodiment includes: compounding the rotation of the spindle of the workpiece with the radial feed motion of the pneumatic grinding head 22, performing a uniform grinding motion at a constant linear speed along the involute direction of the tooth surface, and simultaneously Make uniform motion in the direction of tooth width to realize the polishing of the entire tooth surface of the gear.

[0041] The workpiece of the large-module gear tooth surface polishing equipment described in this embodiment is processed by a dry process.

[0042] The cost advantage of the present invention: the post-heat forming gear grinding process is moved forward...

Abstract

The invention provides polishing equipment for a tooth surface of a large-modulus gear and a polishing process. The polishing equipment for the tooth surface of the large-modulus gear comprises a numerical control gear edge milling machine tool, and is characterized in that a pneumatic control mechanism is mounted on one side of a milling cutter shaft of the numerical control gear edge milling machine tool, the pneumatic control mechanism comprises a pneumatic tool capable of rotating at a high speed, and the end part of the pneumatic tool is provided with a pneumatic grinding head which can be linked with a workpiece shaft and move along the involute of the tooth surface of a workpiece to polish the workpiece. According to the polishing equipment, transformation is directly carried out on a chamfering machine, and newly designed equipment is not needed; and the two working procedures are completed by the same equipment, so that the clamping frequency is reduced, and meanwhile, the occupied area of the equipment is further reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a large-module gear tooth surface polishing equipment and a polishing process. Background technique [0002] At present, large modulus tooth surface finishing is generally used for tooth surface finishing by fine rolling and profile grinding. [0003] 1. The cutting tool life of precision rolling is long, the processing time is long, and the tool cost is high; [0004] 2. The efficiency of the forming mill is low, the processing cycle is long, the equipment investment is large, and the unit cost is high. [0005] The gear hobbing process in the existing gear tooth surface finishing process includes gear milling plus hobbing, chamfering, thermal post-forming grinding, etc.; different processes require different equipment to achieve, such as milling and chamfering. figure 1 The edge milling machine tool shown in the figure can be realized, but the formin...
