Abstract

Serial and tandem apparatus for manufacturing hypoid gears, including a tandem mechanism, a revolving mechanism, a workpiece spindle, a tool spindle, plural driving motors and workbenches. Each of the workbenches is provided with slide rails or slide channels connected in series. The tool holder and the workpiece holder are mounted by a tandem fitting for reducing accumulated errors of the entire apparatus and ensuring higher precision as compared to a serial fitting. The tandem fitting may also provide two revolving degrees of freedom and a translational degree of freedom along an arbor of the tandem fitting thereby providing more revolving degrees of freedom and increasing the number of freedom for manufacturing the hypoid gears. In other words, given apparatus for manufacturing hypoid gears of the same size, the apparatus of this invention can serve to manufacture hypoid gears each of a larger diameter.

Description of the invention (1) [Technical field to which the invention belongs The present invention relates to a machine tool for manufacturing a halberd gear [prior art] Scarf 4 :: making =; useful tooth shape due to the maturity of CNC machine technology over the years Trimming to create low-yin: Erbu: The authors have successively published a lot of information about the benefits of trimming techniques. Many of these low-noise tooth shapes cannot be transmitted on traditional halberd gear manufacturing machines. Due to the fact that the manufacturing machine cannot be further broken and the machine steals itself, the cumulative error is large. The multi-axis halberd gear system & machine as U.S. Patent Publication No. 4 9 8 1 4 0 2 has a total machine of six degrees of freedom, including three rotary axes (knife

With axis, workpiece axis and machine tooth root angle axis) and three translation axes (X, Y, Z ^, the spatial relationship between the tool axis and the workpiece axis are determined by the machine tooth root angle axis and three straight translation axes (X, γ, Z) To describe, the machine simulates the tool on the cradle: ί: There is a considerable limit on the tilt ', and the tool tilt-generally compensates for the difference in the pressure angle of the second gear pressure of the tool, and has a phase δ when reducing the type of pressure angle of the tool blade. WIf〇 (World Intellectual Property Rights Organization) Patent Bulletin No. W0 02 / Qiu + 1 ^ 3 Ring Bevel Gear Manufacturing Method and Manufacturing Machine, its overall machine Γ ^ 1, degrees of freedom, including three rotary axes (Tool axis, workpiece axis and tooth ^) and two translation axes (X, γ, z), the gap between the tool axis and the workpiece axis, off = from the root angle axis and three right-angle translation axes (X, γ, z) ) Describing 1233847 --- "-5. Description of the invention The patent of the connecting rod mechanism is the same as the tooth cutting disk and the five-axis processing device). In other words, it seems that his halberd gear is connected in a comprehensive manner in connection with each work. Inside the hair heart lonely hidden the invention "The machine has more (2) Rotate the 'three books in real Japan and Japan', and the entire three rounds will refer to a kind of gear that shrinks to a maximum of one manufacturing machine platform. The aforementioned connection will create gear capacity. The masters are mostly manufactured to the smallest, including the parallel moon dagger, and to a lesser extent, the utility model has the same characteristics as the rotating shaft of the patented machine.

A or work notification bulletin package (B needs to be more complicated and poor, § There are many workpiece tables, due to the limitation of freedom and the previous one. There is a limitation of No. 62—1 6 24 1 7 No. n—2628 1 No. 6 for the bevel gear contains five translation axes (X, γ, Z, V, ϋ, W, C three axes), the freedom of the machine's freedom, but its freedom of rotation It has not been increased, and continuity in series will affect accuracy. Traditional uranium gear manufacturing machines all use series convolution to affect accuracy, and the degree of freedom of rotation is not limited. The degree of freedom is related to the fact that there are many types of mechanisms, so that the technology is fundamental, and the gear system is based on the ability of the machine to string and merge the teeth, and to promote the various defects derived from it. The research spirit eventually developed the machine. ”For a more traditional halberd gear manufacturing, and the cumulative error of the machine itself to make a larger halberd gear. The design of the combined halberd gear manufacturing machine, especially the wheel manufacturing machine design, makes the machine in production and Accumulation of the machine itself The difference of the gear accuracy can be manufactured.

Using the characteristics of the parallel mechanism, two degrees of freedom of rotation of the tool holder and translational degrees of freedom along the tool rotation axis are provided. The base (or tool holder) is set up on a vertical XY-direction platform, and uses the turning mechanism to achieve the freedom of adjusting the tooth root angle of the machine. There is one degree of freedom of rotation along the tool rotation axis and the workpiece rotation axis. The overall machine contains eight degrees of freedom ( Five degrees of freedom of rotation and three degrees of freedom of translation), the overall degree of freedom of rotation is more than all traditional halberd gear manufacturing machines, but because of the use of a hybrid series and parallel machine architecture, the overall machine error accumulation is small, and the accuracy is not It will decrease, and because there are more degrees of freedom of rotation, the freedom of manufacturing of the gear can be greatly increased. The secondary object of the present invention is to provide a serial and parallel halberd gear manufacturing machine, which is compatible with the main halberd gear machines in the past, including the face milling manufacturing method and the face rolling manufacturing method. In addition, it can use computer numerical control to perform various first- and second-order tooth shape corrections, such as worm angle correction, pressure angle correction, tooth print skew correction, and tooth print width correction.
