Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but does not impose any limitation on the present invention.

[0030] like Figure 1-6 As shown, a vertical milling machine for precisely machining gears includes a base, a bed with guide rails, a lift table, a longitudinal workbench 17, a transverse workbench, a power system, a speed change mechanism, and an electrical control system; it also includes a power output head 4 , the power output head 4 simultaneously outputs power to the gear hob 1 for milling gears and the mandrel 24 that drives the workpiece 21 to rotate, so as to realize accurate transmission between the workpiece and the gear hob 1 .

[0031] The power output head 4 includes a hob cutter bar 22, a hob bar pull rod 5, an end mill spindle, an active helical gear 2, and an output helical gear 3. On the main shaft, the active helical gear 2 and the gear hob 1 are installed on the hob cutter...

Abstract

The invention provides a vertical milling machine for precisely processing a gear, belonging to the technical field of machining a machine tool. The vertical milling machine for precisely processing the gear comprises a base, a machine body with a guide rail, a lifting platform, a longitudinal work platform, a horizontal work platform, a power system, a speed shifting mechanism, an electric appliance control system and a power output head, wherein the power output head outputs the power to a gear hobber used for milling the gear and a central spindle used for driving a workpiece, the transmission ratio relationship between a main shaft of the milling machine and a processed gear is provided with a strict internal relation transmission chain, so that the accurate transmission between the workpiece and the gear hobber can be realized. The processing of a straight toothed spur gear, an involute spline and a chain wheel can be realized, and after a differential mechanism, the processing of a helical-spur gear can be realized, and a pinion cutter which is small in diameter and has low requirement on the precision of a worm wheel can be processed. The vertical milling machine of the invention solves the difficulty that the precise level can not be achieved by using a disc milling cutter form copying method for the milling machine to process the spur gear, has the advantages of low cost and convenient and rapid assembly and disassembly, and can be used for various common vertical milling machines.

Description

technical field [0001] The invention relates to a machining machine tool, in particular to a vertical milling machine capable of precisely machining gears. Background technique [0002] Common vertical milling machines commonly used at present generally include a base, a bed with guide rails, a lifting table, a longitudinal table, a horizontal table, power and electrical control systems, lubrication and cooling fluid circulation systems, etc. This vertical milling machine has a general It has the characteristics of strong resistance and wide application range. [0003] But when processing gears with this vertical milling machine, the gears can only be processed by the profiling method, and the processing of the tooth grooves of the gears can be realized with a disk-shaped finger-forming milling cutter. However, since the transmission ratio relationship between the spindle of the milling machine and the gear to be processed does not have a strict internal connection transmis...
