汽车检具中L什么意思
Cars are very common in our lives, but the manufacture of cars is not simple. It takes many procedures to complete the production. Automobile inspection tool is one of them. Automobile inspection tool is a kind of testing tool specially manufactured according to specific requirements. Nowadays, automobile inspection tool processing has become an indispensable technology for modern automotive manufacturing. So what are the characteristics of automobile inspection technology?
The detection of vehicle inspection holes, body stamping parts for many important holes and flanges, etc. need to be tested separately. In the design of the inspection equipment, a convex platform with a thickness of about 1mm is usually added to the concrete surface of the inspection. The center of the convex platform is on the same axis as the center of the workpiece hole. The diameter is 5mm larger than the aperture, and the double line is used to detect the convex platform. When the accuracy of the test hole is relatively high, the positioning hole is used to detect it with Stoppers and Bushing.
For the design of the bottom plate assembly of the vehicle inspection equipment, the specific surface is stretched along a certain distance in the direction of the reference surface, so that the minimum point is greater than 150 mm thick, so as to ensure that the inspection is specific enough strength, while trying to check the specific bottom surface, That is, the upper surface(base surface) of the bottom plate assembly, in the integer position of the body coordinate system. The specific bottom plate assembly is generally composed of a substrate, a groove steel(when necessary in the middle of the processing of steel), a positioning block, and a universal wheel. When the substrate is inspected and fixed, other components can be selected according to the actual situation. Standard model.
In the process of mould making, the cutting and punching process has always been a difficult point in the mold manufacturing process, especially some large automobile molds with complex structure such as oblique cutting, oblique punching, and oblique turning. If the determination of the repair edge line is very difficult to use the traditional production method, and it is necessary to repeatedly explore several times or even more than ten times, it has brought a great workload to the locksmith and processing equipment, and not only put forward a high level of skill for the locksmith. requirement, And it will seriously affect the commissioning of the post-process mold. In fact, there are many cutting edge materials for trim and burrowing modes that use alloy steel for cost considerations. If traditional cutting edge molding methods are used, it is inevitable that the blade will be oversoldered several times because the material is in multiple times. In the process of surfacing, It is easy to crack and cause the veneer to be scrapped, and it has to be reprocessed. This will not only lag the cycle, but also the mold production cost will increase significantly.
If laser cutting technology is used, laser cutting can be used to replace the trim and punch process for the developed automotive parts and wait for the prototype to be successfully tested. The samples obtained from the cutting are directly used in the next flanging process for testing, and the final samples obtained are compared with the inspection tools. If there is any difference, the last trim line is trimmed and cut again through the computer until it is successful. The whole process saves two processes, completely changing the traditional single-line serial production method, greatly shortening the process flow and reducing the mold production cost.
We can tell from the above introduction that automobile inspection technology has obvious advantages in the process of making modern molds and can improve production efficiency and control quality. For mass-produced products, such as auto parts, to replace professional measurement tools such as smooth plug gauge, thread plug gauge, external diameter card gauge, etc..
