Numerical control bevel gear tooth top chamfering machine

Abstract

The invention provides a numerical control bevel gear tooth top chamfering machine, and belongs to the technical field of machining equipment. According to the machine, the problems that an existing chamfering machine is low in precision, complex in structure, high in manufacturing cost and not easy to popularize are solved. The numerical control bevel gear tooth top chamfering machine comprises a base, a box body and a worktable, wherein the box body and the worktable are arranged on the base, a transverse guide rail is fixedly connected to the base, the worktable is slidably connected to the transverse guide rail, the worktable moves in the X-axis direction, a supporting plate is fixedly connected to the worktable, a gearbox is arranged on the supporting plate, a rotary table is arranged above the gearbox, a vertical guide rail is fixedly connected to the box body, a machine head is slidably connected to the vertical guide rail, the machine head moves vertically in the Z-axis direction, a transmission motor is arranged at the top of the machine head, a ball head milling cutter is arranged on the bottom surface of the machine head, and the ball head milling cutter is driven to operate through the transmission motor. Through the improvement of the structure and the linkage track of a traditional chamfering machine, the machine has the advantages of being higher in chamfering precision, simple in structure and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and relates to a chamfering machine, in particular to a numerically controlled bevel gear tooth top chamfering machine.

Problems solved by technology

[0002] With the development of production technology and the improvement of use requirements, gears are developing in the direction of high precision, high strength, high load, low noise, light weight and long life. Chamfering gear teeth is the key to controlling gear noise and improving Meshing accuracy is a very important technological measure to reduce meshing impact, prevent stress concentration, and eliminate interference to prolong the service life of gears. It has attracted widespread attention and attention from the gear manufacturing industry at home and abroad. It is determined that there is no uniform standard, only the chamfering standards and related regulations specified by each company. At present, most domestic companies use the manual chamfering method. The staff uses an angle grinder to grind the gear tooth tops. Chamfering, but artificial chamfering requires high technical level of workers and takes a long time for production, which reduces the production efficiency of the enterprise. Some enterprises have developed tooth top chamfering machines for mechanized processing

[0003] For example, the application number is 200510122359.7, which discloses a CNC spiral bevel gear addendum chamfering machine. The invention adopts the double-axis cross-linked grinding head mechanism and the linear motion of the two CNC axes installed on the column and installed in the work. The three-axis linkage of the rotating numerical control axis on the table completes the chamfering of the tooth top of the spiral bevel gear. Since the operation mode of the worktable is troublesome positioning of the flip movement, the worktable is in an inclined state when chamfering the bevel gear. The edge precision is low, and its grinding head mechanism structure is complex and the manufacturing cost is high. It is easy to be limited by the change of the pressure angle in the tooth length direction, so it is not easy to popularize
