牛头刨床的拔叉工艺设计_牛头刨床工作视频

早期的木匠经常刨削木头，以提高其表面质量，如图3-77所示。在现代机械制造中，人们设计出刨床完成工件的刨削工作。图3-78是工厂里经常使用的牛头刨床，其工作原理是电动机带动曲柄1旋转，通过滑块2和导杆3将旋转运动转化为左右摆动，再通过杆5推动刨刀滑块6进行刨削工作。由于牛头刨床采用平面连杆机构，故存在急回特性，有利于提高工效。

Abstract

Mechanical Manufacturing Engineering Course design is finished we learn all the basic courses university, technical basic courses and specialized courses after most of the. This is the course of the study prior to graduation each course an in-depth and comprehensive general review is a theory with practical training, so it in our four years of university life plays an important role.

The design of the shaper of the fork, including the parts diagram, rough and assembly drawings each one, the mechanical process the card and a card with the process. First, we should be familiar with parts and understand their role, which is located lathe speed change mechanism, the main effect from the shift. Then, according to the nature of parts and components map to determine the roughness of the end of the size and rough machining allowances. Fork process to finalize a road map to develop the workpiece clamping program, draw fixture assembly drawing.

This design is fork Shaper milling machining process and ends special fixture design. From the appearance of parts of the structure, it looks complicated and difficult process, so the choice is casting parts. Its main processing is the hole surface, surface and both ends of the side fork Crossings, notch, in the process because of surface precision machining precision holes easier than the guarantee. Therefore, the first plane used in the design principles of post-holes, and holes and the plane is divided into roughing and finishing processing stage to ensure accuracy. In this design, first to a base level of a surface processing, and then, then the corresponding holes in the base-level processing. In the following processes, are the holes for the locating datum, processing fork Crossings at both ends of surface (relative to the hole location accuracy) slot and the inclined plane, in the processing were used milling machine, drilling machine. And designed a special face milling fixture. As the size of the parts is not required clamping force is not. Therefore, the clamping means are manually clamped, clamping it simple, mechanism design is more convenient to meet the clamping requirements.

Personally, I hope that through the course design, understanding and awareness of general machinery parts production process, have learned to consolidate and deepen the technical knowledge of basic courses and specialized courses, theory with practice, from exercising their own analysis of the problem, ability to solve problems for future work lay a good foundation, and for follow-up courses of study in future.

Abstract

Mechanical Manufacturing Engineering Course design is finished Zai we learned the whole basis of the University of De classes, basic technical courses and most of the specialized courses after the. This is our school design during the course prior to the study of Yi Ci-depth comprehensive review of the total, Yeshi a theory with practical training, so it in our four years of university life plays an important role.

The design of the shaper of the fork, including the parts diagram, rough and assembly drawings each one, the mechanical process the card and a card with the process. First, we should be familiar with parts and understand their role, which is located lathe speed change mechanism, the main effect from the shift. Then, according to the nature of parts and components map to determine the roughness of the end of the size and rough machining allowances. Fork process to finalize a road map to develop the workpiece clamping program, draw fixture assembly drawing.

This design is fork Shaper milling machining process and ends special fixture design. From the appearance of parts of the structure, it looks complicated and difficult process, so the choice is casting parts. Its main processing is the hole surface, surface and both ends of the side fork Crossings, notch, in the process because of surface precision machining accuracy than the hole is hard to guarantee. Therefore, the first plane used in the design principles of post-holes, and holes and the plane is divided into roughing and finishing processing stage to ensure accuracy. In this design, first to a base level of a surface processing, and then, then the corresponding holes in the base-level processing. In the later processes, are the hole positioning base, processing fork Crossings at both ends of surface (hole position accuracy relative to height) slot and the inclined plane, in the whole processing, respectively Le milling machine, drilling machine. And designed a special face milling fixture. As the size of the parts is not required clamping force is not. Therefore, the clamping means are manually clamped, clamping it simple, mechanism design is more convenient to meet the clamping requirements.

Jiu me personally, I 希望 can make this a course design, Liao Jie and understanding of ordinary machines parts production process to consolidate and deepen already learned Technical Basic Courses and Professional's knowledge of theory with practice, from exercise Zijifenxi Wen Ti, ability to solve problems for future work lay a good foundation, and for follow-up courses of study in future.
