Description
本發明為有關一種直進式刮齒刀，尤指一種直進式刮齒刀的修整方法。The invention relates to a straight-through type scraping knife, in particular to a dressing method of a straight-through type scraping knife.
齒輪為傳遞動力和運動的基礎元件，具有傳動效率高、使用壽命長、安全可靠等優點，已經成為許多機械產品不可缺少的傳動部件。Gears are the basic components for transmitting power and motion. They have the advantages of high transmission efficiency, long service life, safety and reliability, and have become an indispensable transmission component for many mechanical products.
齒輪的設計與製造水平將直接影響到機械產品的性能和質量，為了達到高品質的需求，齒輪一般精修齒面可分為磨齒及刮齒兩種方式為主，雖然磨齒具有較高的精確度，但由於磨削的過程相當耗時、且會產生許多油霧磨粒等，故較不符合環保與經濟效益，所以一般中高精度的齒輪修整大多使用刮齒的技術，而且刮齒刀的重複使用性高，修整工件齒輪時間遠較磨削少許多，比較符合經濟效益。The design and manufacturing level of the gear will directly affect the performance and quality of the mechanical products. In order to achieve high quality requirements, the gears can be divided into two types: grinding and scraping. Although the grinding teeth have higher The accuracy, but because the grinding process is quite time-consuming, and will produce a lot of oil mist abrasive particles, etc., it is less environmentally friendly and economical, so the general high-precision gear trimming mostly uses the technology of scraping, and the teeth are scraped. The reusability of the knife is high, and the time for dressing the workpiece gear is much less than that of grinding, which is more economical.
在美國發明專利第US4831788號中，揭示了一種磨削刮齒刀之齒側面的設備，其是以滾動生成法(rolling-generation method)磨削刮齒刀的齒側面，不過，由於上述設備在磨削的過程中，還需要額外進行磨床的附加以及安裝與拆卸刮齒刀的步驟，因此於日本專利第JP4524159號中，提出另一種刮齒刀的磨削方法，其提供一旋轉齒輪刮齒刀磨床，該旋轉齒輪刮齒刀磨床包含有一機器立柱、一於該機器立柱上直線移動的滾柱滑架、一可轉動的設置於該滾柱滑架上的工件主軸、一用於該工件主軸的旋轉運動及該滾柱滑架的直線運動的傳動裝置、一磨輪以及一旋轉和推進該磨輪的作動裝置，其特徵在於該磨輪利用一錐形的第二工作區域與被加工的該旋轉齒輪刮齒刀的齒頂切向接觸，以便以凹凸方式磨削該齒頂並獲得所要的頂圓直徑尺寸，以將被加工的旋轉齒輪刮齒刀的頂圓直徑縮小至適當的尺寸。In the U.S. Patent No. 4,831,788, an apparatus for grinding the flank of a squeegee is disclosed which is a flank of a squeegee by a rolling-generation method, however, In the process of grinding, an additional step of attaching the grinding machine and a step of attaching and detaching the squeegee are required. Therefore, in the Japanese Patent No. JP4524159, another method of grinding the squeegee is provided, which provides a rotating gear squeegee. a rotary cutter gear grinding machine comprising a machine column, a roller carriage linearly moving on the machine column, a rotatable workpiece spindle disposed on the roller carriage, and a workpiece for the workpiece a rotary motion of the main shaft and a linear motion of the roller carriage, a grinding wheel, and an actuating device for rotating and advancing the grinding wheel, characterized in that the grinding wheel utilizes a tapered second working area and the rotating machined The tooth tip of the gear scraper is tangentially contacted to grind the crown in a concave-convex manner and obtain the desired diameter of the top circle to the top circle of the rotary gear scraper to be processed A reduced diameter to a suitable size.
然而，當該刮齒刀經過多次的對齒輪之齒面進行刮齒後，其與該齒面接觸的切緣(cutting edge)將會逐漸被磨耗，而使得對齒輪所進行的精修齒形作業，其精度將會下降，因此必須對該刮齒刀進行修整，再者，習知為五軸的刮齒刀磨床，例如美國Gleason公司所生產型號為Gleason-Hurth SRS 410的磨床，其對該刮齒刀進行修整時，由於為乾式加工，不僅加工速度慢，且其為針對刮齒刀此種特別磨削需求所設計的磨床，額外增加廠商的設備成本，故仍有改善的空間。However, when the squeegee scrapes the tooth surface of the gear a plurality of times, the cutting edge that is in contact with the tooth surface will be gradually worn, and the finishing teeth of the gear are made. The accuracy of the work will be reduced, so the razor must be trimmed. Furthermore, it is a five-axis squeegee grinder, such as the Gleason-Hurth SRS 410 grinder produced by Gleason Corporation of the United States. When the doctor blade is trimmed, it is not only a slow processing speed, but also a grinding machine designed for the special grinding requirement of the scraper knife, which additionally increases the equipment cost of the manufacturer, so there is still room for improvement. .
本發明的主要目的，在於解決刮齒刀經過多次的對齒輪之齒面進行刮齒後，其與該齒面接觸的切緣將會逐漸被磨耗，而使得對齒輪所進行的精修齒形作業精度將會下降的問題，以及習知為五軸的刮齒刀磨床為乾式加工，不僅加工速度慢，且其為針對刮齒刀此種特別磨削需求所設計的磨床，額外增加廠商的設備成本的問題。The main object of the present invention is to solve the problem that after the tooth knives of the gear teeth are scraped by the squeegee after a plurality of times, the cutting edge which is in contact with the tooth surface will be gradually worn, and the finishing teeth of the gears are refined. The problem of the accuracy of the work will be reduced, and the five-axis scraper grinding machine is dry-processed, which not only has a slow processing speed, but also is a grinding machine designed for the special grinding demand of the scraping knife. The cost of equipment costs.

提供一直進式刮齒刀，該直進式刮齒刀包含複數個相間隔排列的螺旋齒；
定義該螺旋齒具有一待加工側；
將該直進式刮齒刀定位於該工件軸，且使該直進式刮齒刀的該待加工側與該輪磨工具相接觸；
轉動該輪磨工具，並令該直進式刮齒刀依一可變轉動量圍繞該第一軸向旋轉且同時依一第一可變移動量沿該第一軸向移動，而該輪磨工具依一第二可變移動量沿一分別與該第一軸向及該加工軸垂直的第二軸向移動，使該輪磨工具相對該直進式刮齒刀進行一螺旋運動以對該待加工側執行一修整作業；
其中，於該修整作業中，該可變轉動量與該第一可變移動量的比值為根據該直進式刮齒刀的一齒廓參數計算得到的一第一變數，該第二可變移動量與該第一可變移動量的比值為根據該直進式刮齒的該齒廓參數計算得到的一第二變數。A dressing method for a straight-through type knives is to use a gear forming wheel mill, the gear forming wheel mill comprising a tool holder and a workpiece holder moving along a first axial direction and opposite to the tool holder, the tool holder The machining shaft has a machining shaft that rotates the workpiece, and the workpiece holder has a workpiece shaft that rotates with the first axial axis. The trimming method comprises the following steps:
Providing a continuous-type squeegee cutter, the straight-through squeegee cutter comprising a plurality of helical teeth arranged at intervals;
Defining that the helical tooth has a side to be processed;
Positioning the straight-type razor blade on the workpiece shaft, and contacting the side to be machined of the straight-type razor blade with the wheel grinding tool;
Rotating the wheel grinding tool and rotating the straight-type squeegee about the first axial direction by a variable amount of rotation while moving along the first axial direction according to a first variable movement amount, and the wheel grinding tool Moving a second variable movement amount along a second axial direction perpendicular to the first axial direction and the machining axis, causing the wheel grinding tool to perform a helical motion with respect to the straight-feed type scraping knife to process the workpiece Perform a trimming operation on the side;
In the trimming operation, the ratio of the variable rotation amount to the first variable movement amount is a first variable calculated according to a tooth profile parameter of the straight-through type cutter, the second variable movement The ratio of the amount to the first variable amount of movement is a second variable calculated from the profile parameter of the straight-through scraping tooth.
