The design of tool lighting is generally carried out after the formulation of the mechanical processing process of parts as a function of the specific requirements of a certain process. During the formulation of the process, the possibility of implementing the luminaire must be fully taken into account. The quality of design of the tooling light must be measured by the question of whether it can stable the quality of treatment of the part, high production efficiency, low cost, practical elimination of fleas, operation Sure, an economy of labor and easy manufacturing and maintenance.
The quality of design of the tooling light must be measured by the question of whether it can stable the quality of treatment of the part, high production efficiency, low cost, practical elimination of fleas, operation Sure, an economy of labor and easy manufacturing and maintenance.
1. Basic principles of the design of the luminaire
1. Satisfy the stability and reliability of the positioning of the part during use;
2. Have enough loading or tightening force to ensure the process of processing the part on the tool lighting;
3. Cleans up the simple and easy operation during tightening;
4. Vulnerable parts should be quickly replaced.
5. Respond to the reliability of the repeated positioning of the luminaire during adjustment or replacement;
6. Avoid complex structure and costly cost as much as possible;
7. Choose standard parts as components as possible;
8. Form the systemization and normalization of internal products of the company.
2. Basic knowledge of the tools and the design of lighting
An excellent machine-tool luminaire must meet the following basic requirements:
1. Ensure the machining accuracy of the part. The key to ensuring the precision of the machining is to correctly select the positioning reference, the positioning method and the positioning components. The luminaire can meet the rooms for machining the room.
2. Improve production efficiency. The complexity of special lights must be consistent with the production capacity situation, and various fast and effective tightening mechanisms must be used as much as possible to ensure easy operation, shorten the auxiliary time and improve production efficiency.
3. Good process performance. The structure of special lights must be simple and reasonable, and be practical for manufacturing, assembly, adjustment, inspection, maintenance, etc.
4. Good performance. Tool lights must have sufficient resistance and rigidity, and must be easy to use, save work, safe and reliable. Under the premise that the objective conditions allow and economical and applicable, mechanized tightening devices such as pneumatic and hydraulic should be used as much as possible to reduce the intensity of the operator’s work. Working devices must also be practical for eliminating fleas. If necessary, the elimination structures of fleas can be configured to prevent fleas from destroying the positioning of the room and damaging the tool, and preventing the accumulation of shavings from causing a large amount of heat to cause the deformation of the process system.
5. Good economy. Special lights should use standard components and standard structures as much as possible, and endeavor to be simple in structure and easy to make to reduce the manufacturing cost of lighting. Consequently, during the design, the necessary technical and economic analysis of the luminaire plan must be carried out according to the control and the production capacity to improve the economic advantages of the lighting in production.
3. Presentation of the standardized design of tool lights
1. Basic methods and tool design stages
Original information to prepare the design of the tool lighting before design include the following content:
(1) Design notice, finished part drawing, blank drawing and process route and other technical information, understand the technical requirements for processing each process, positioning and tightening plan, content of the previous process, the situation of The ignition, the machine tools used in the treatment, tools, inspection and measurement tools, treatment allocation and use of the cut, etc.;
(2) Understand the production batch and the demand for lighting;
(3) Understand the main technical parameters, performance, specifications, the accuracy of the machine machine used and the connection dimensions of the structure of the lighting room, etc.;
(4) Inventory of standard lighting materials.
2. Problems in the design of tool lighting
The design of the luminaire has generally a single structure, which gives people the feeling that the structure is not very complicated. Unnecessary problems will inevitably occur:
(1) The white room margin to be treated. This makes the size empty too large and interferes. Therefore, you need to prepare an empty drawing before design. Leave enough space.
(2) The softness of withdrawal of the chips from the luminaire. During the design, due to the limited treatment space of the tooltip, the light is often designed with a relatively compact space. A bad flow of chip liquid, which will be given in the future. Therefore, the problems that arise during the processing process should be taken into account at the start of real practice.
(3) The overall opening of the luminaire. The ignorance of the opening makes it difficult for operators to install cards, long-lasting and a high intensity of labor, and a design taboo.
(4) Basic theoretical principles of the design of the luminaire. Each set of lights must undergo countless tightening and relaxation actions, it can therefore meet the requirements of the user at the beginning, but the addition should have its precision retention, so do not design something that is contrary to Principles. Even if you may have the chance to do it now, there will be no long -term sustainability. Good design must be tempered by time.
(5) Replacement of the positioning element. The positioning elements are seriously worn, therefore a quick and practical replacement must be taken into account. It is best not to design in larger parts.
The accumulation of experience in the design of the luminaire is very important.
