Inspection of inspection hole of car inspection tools, inspection of many main holes and flanging needs of body stamping parts alone. In the planning of inspection tools, a convex platform with a thickness of about 1mm is added to the surface of inspection details. The base of the convex platform and the workpiece hole base are on the same axis, with a diameter of 5mm larger than the hole diameter. When the precision request of the hole under test is high, the method of locating hole is checked by plug gauge and bushing.

As for the planning of the car inspection tool bottom plate assembly, in the inspection details, the outer surface stretches a certain distance along the direction of the datum plane, making its lowest point greater than 150mm thickness, so as to ensure that the inspection details have satisfactory strength. Together, the inspection details of the bottom surface, i.e. the upper surface of the bottom plate assembly (the base surface), are in the integral position of the body coordinate system. The inspection detailed floor assembly is generally composed of base plate, channel steel (with i-steel in the middle if necessary), positioning block and universal wheel. When the base plate is fixed in inspection detail, other parts can choose the standard type according to the practical situation.

In the manufacturing process of molds, trimming and punching processes are always the difficulties in the manufacturing process of molds. If the judgement of repair sideline is chosen traditional manufacturing method good not simple, and need to explore a few times even more than ten times repeatedly, brought great workload to the pliers, processing equipment, not only to the pliers skill level put forward a higher request, and will seriously affect after the procedure mold debugging. And practice, there are a lot of trimming and piercing die cutting edge material thinking chose alloy steel from the capital, if choose the trimming die manufacture with traditional method, it inevitably repeatedly surfacing welding was carried out on the edge, because the data in the process of repeatedly surfacing, easy cracking and cause insert invalid, feed has to rework, so not only cycle will be lag, and mold manufacturing capital also add substantially.

If choose laser cutting skills, on the development of car parts, such as drawing a test after the success, can use the laser cutting instead of trimming, punching process, the car fixture for open, sideline repair the cut of the proceeds of the samples are directly used in the flanging process to carry on the test, the income of all samples are compared with fixture, if there's a difference, through computer to previous sideline repair can be cut again, until success. All processes save two processes, completely changing the traditional single-line serial manufacturing method, greatly shortening the process flow and reducing the cost of mold manufacturing.

What characteristics of car fixture processing skills is Shared here today, we can know, after the introduction of auto car inspection processing skills in modern mold manufacturing process has obvious advantages, can produce efficiency and quality control, progress is suitable for mass production of goods, such as car parts, instead of professional measurement tools, such as smooth plug gauge, thread plug gauge, diameter gauge, etc.
