Commonly used tips in mechanical processing, worth collecting-roboticist

Usually in the industry, the mechanical processing process specification is one of the process documents for processing processes and operating methods. It is a process document written in a prescribed form under specific production conditions, which is used to guide production after approval. Today we have summarized some tips for everyone to refer to.

In mechanical processing, remove the jaws of the vise and machine two M4 threaded holes. Two 1.5mm thick steel plates 2 should be flush with the jaws. Use aluminum countersunk rivets to rivet on a 0.8mm thick hard brass plate 3 and fasten it to the jaws with M4 countersunk screws 1, forming a durable soft jaws. This can also protect the parts from being pinched and has interchangeability. It is not convenient to use magnets to absorb small parts (expensive parts) in mechanical processing. An iron plate 2 can be sucked under magnet 1, which not only attracts many small pieces, but also automatically tilts them into the collection box when the iron plate is pulled open. Not enough to impress, but very practical. During the transmission of the belt pulley in mechanical processing, the belt pulley often slips between the wheel shaft. Use a 15~18mm drill bit to scratch a series of grooves on the wheel shaft, which can form adsorption force to prevent slipping. The boss will reward you for turning waste into treasure. 04 In machining, when the Hex key has a short handle and cannot exert force, a pipe with an inner diameter slightly larger than the wrench can be milled from a section of groove, and the wrench can be inserted into the groove as a long handle.

In addition, in the mechanical processing of Shenzhen, there are many workpieces that are not produced in one go. However, when the workpieces are produced, they are just a rough model. If they become real products after leaving the factory, some mechanical equipment needs to be used for mechanical processing according to different product requirements, in order to ultimately become a valuable product.
Four Principles
1 Benchmark First
When using mechanical equipment to process products, it is necessary to determine a reference plane, so that there can be a positioning reference during subsequent processing. After determining the reference plane, the reference plane must be processed first. 2. Dividing processing stages
When machining products, different degrees of processing are required according to different product requirements, and the degree of processing needs to be divided. If the accuracy requirements are not high, then a simple rough machining stage is sufficient. The progress requirements of the product are becoming increasingly strict, and the subsequent stages of semi precision processing and precision processing will need to be carried out. 3. Face before hole
When machining, for workpieces such as supports, the brake requires both planar and mechanical hole processing. In order to reduce the accuracy error of the processed holes, machining the plane first and then the holes is beneficial for reducing the error. 4. Finishing
This processing principle roughly refers to some polishing and polishing processes, which are usually carried out after the entire product structure is completed.
