It includes: scribing, chiseling, filing, sawing, drilling, reaming, tapping and tapping, straightening and bending, riveting, scraping, grinding and measuring, sketching parts and heat treatment.

Question 4: What is the fitter's main job? 1. Work tasks.

The tasks undertaken by mechanics and locksmiths in different enterprises and factories because of their specific conditions.

There are some differences, but in general, they will not go beyond the following aspects.

1. Overhaul refers to completely disassembling equipment, repairing benchmark parts, replacing and repairing the mill.

Damaged parts, scrape or grind all guide rail surfaces, completely eliminate defects and restore the original equipment.

Degree, performance and efficiency, close to or reach the factory standard.

2. During the intermediate repair, the equipment will be partially disassembled, and the worn parts will be repaired or replaced and corrected.

Some uncoordinated links between parts, adjust coordinates to restore and maintain equipment.

Accuracy, performance and efficiency until the next maintenance.

3. Minor repairs mean cleaning the equipment, some parts are disassembled and inspected, and replacement and maintenance are less.

Measure the worn parts, adjust and tighten the mechanism to ensure that the equipment can meet the production process requirements.

4. Secondary maintenance is mainly based on mechanical (electrical) maintenance workers, supplemented by operators.

Check and repair equipment parts, repair or replace severely worn parts and clean them up.

Cleaning and inspection, restore local accuracy to meet process requirements.

5. A repair is an overhaul of fine, large and thin equipment, which requires a certain amount of manpower.

Not to mention material and financial resources, it will take a long time to stop, and the equipment is also divided.

Repair, make it in good condition, meet the process requirements.

6. Regular precision inspection and precision adjustment refer to precision machine tools and bearings.

Key equipment in key processing procedures, especially high-precision equipment, should be overhauled in addition to planned maintenance.

It is also necessary to check its accuracy regularly at maintenance intervals. If out-of-tolerance or abnormality is found.

For example, mechanics and fitters will make adjustments, and the accuracy can only be adjusted when it is necessary to scrape or replace larger parts.

When, in the case of not affecting the processing quality, can be repaired in the latest plan.

Except ...

7. Organize the maintenance for the temporary damage of the faulty maintenance equipment.

8. Repair of accident repair equipment.

9. Equipment transformation is to solve two kinds of wear and tear of equipment (natural wear and no wear).

Formal wear), especially intangible wear (technical aging), advanced, mature and reliable.

Adopt new technologies, new materials and new processes to rationally and reliably use old equipment and machine tools.

Economic, practical and effective transformation to meet the needs of production development.

10. The installation and debugging of new equipment refers to the installation of updated or newly added equipment.

Assembly, debugging and acceptance until it is put into use.

Question 5: What are the characteristics of the fitter's scraping pin? Scraping is an ancient processing method and a heavy physical labor. It is simple to use and is not limited by the shape and position of the workpiece and the equipment conditions. Its characteristics are: small cutting amount, small cutting force, small production heat and small clamping deformation. It can obtain higher shape and position accuracy, dimensional accuracy, contact accuracy, transmission accuracy and surface smoothness, so it is still an important manual operation in machinery manufacturing and tool and measuring tool manufacturing or repair.

Question 6: What kind of job is a locksmith? "Clamp" means to clamp or restrict something, such as a vise. "Fitter" refers to the work of assembling various machine parts with various tools such as bench vice, file, scraper, flat shovel and hammer, mainly engaged in the assembly, adjustment and maintenance of various machines. Here, the fitter is called omnipotent.

All kinds of metal products were made by blacksmiths at that time (similar to today's forgers and forgers). With the continuous development of society and production technology, casting and forging processes have also developed, so there is a new division of labor in technology. In the 14 and 15 centuries, locksmith technology was separated from casting and forging technology and became a special type of work. At first, locksmiths could only make some simple metal products by hand, such as locks and rings, but later they became more and more complicated. Now they can make machine parts and assemble machines. Fitter is an important type of work in modern industry.

The locksmith's operation is mainly carried out on the vice with hand tools, so it is called locksmith. This kind of work is complex and meticulous, and the specific operations include: parts measurement, marking, chiseling, filing, sawing, drilling, reaming, tapping and tapping, straightening and bending, riveting, scraping, grinding, tin plating and welding, bearing alloy casting, simple heat treatment (quenching), sheet metal blanking (thin plate) and so on. The locksmith's operation is mostly done by hand, and sometimes by machine.

During the war, the infantry always said to the comrades in other arms: "Cannons can't get bayonets, but we infantry have to solve the battle." It can be said that locksmith is the most basic process in all processing technologies. It is an "infantry" in various crafts.
