Small modulus straight bevel gear CNC gear planer with cutter and adjustment device

Abstract

The invention relates to a cutter relieving and adjusting device of a numerically controlled small-modulus straight-tooth bevel gear shaper. The cutter relieving and adjusting device of the numerically controlled small-modulus straight-tooth bevel gear shaper is characterized by comprising carriage saddles and rams, wherein the carriage saddles are symmetrically mounted on a cradle drum wheel; the rams move on the carriage saddles in a reciprocating manner; each ram is provided with a cutter base support and a cutter base; clamping plates are symmetrically arranged on each carriage saddle fixedly; a brake band is arranged between each two clamping plates; a cutter relieving pull rod is clamped by each brake band; a roller, a hinge pin and a cutter relieving pull rod guide block are mounted at one end of each cutter relieving pull rod; each cutter relieving pull rod is connected with a cutter reliving connecting rod; the other end of each cutter relieving connecting rod is mounted on the corresponding cutter base; a shaft of each cutter base is assembled with holes of the corresponding cutter base support and the corresponding cutter relieving connecting rod; a gear shaping cutter is mounted on each cutter base; and an adjusting mechanism is further arranged on each cutter base support. The cutter relieving and adjusting device of the numerically controlled small-modulus straight-tooth bevel gear shaper has the advantages that large cutter relieving amount and large amount of feed can be obtained, accurate, reliable and stable cutter relieving movement is guaranteed, and machining efficiency and machining precision of a small-modulus straight-tooth bevel gear are improved; and cutter relieving movement is adjusted simply, and the cutter relieving and adjusting device is convenient to operate, and meets requirements of machining of the high-precision small-modulus straight-tooth bevel gear.

Description

technical field [0001] The invention belongs to the technical field of gear planer manufacturing, and in particular relates to a small modulus straight bevel gear numerical control gear planer tool setting and adjustment device. Background technique [0002] Small modulus straight bevel gears are widely used in aerospace, aviation, robot manufacturing and other fields. Small modulus straight bevel gears have a good market prospect and are in great demand as parts of small or micro mechanical transmission components. Since the smaller the gear modulus, the more difficult it is to process, it is difficult to meet the gear tooth shape, tooth direction error requirements and machining accuracy. [0003] The tool of the small modulus straight bevel gear planer completes the tool letting action while doing high-speed reciprocating stroke motion on the guide rail of the tool holder. The so-called movement of the knife is: during the planing work stroke, the planer is lifted and t...

AI Technical Summary

Problems solved by technology

This structure has the following disadvantages: 1. The above-mentioned tool letting mechanism is installed between the tool holder base and the ram, and the structure is relatively complicated, so it cannot be applied to a compact small-module straight-tooth bevel gear planer; 2. The above-mentioned tool letting mechanism The knife letting and returning actions of the mechanism are clamped by the splint mechanism to let the knife pull rod swing the clamping plate, and the knife letting action is not agile and reliable enough; 3. The above knife letting mechanism cannot adjust the knife letting amount due to its structural limitations, so it is in urgent need of development A tool setting and adjustment device for a CNC gear planer for processing small modulus straight bevel gears
