The functions of automobile inspection tools are mainly divided into three stages, and the characteristics of different stages are obviously different. Among them, the product verification stage is the most important link. The automobile inspection tool processing technology directly affects the completion of the overall automobile inspection tool. Therefore, when designing and manufacturing the automobile inspection tool, it is necessary to be familiar with the product and make high-quality and high-standard automobile inspection tools with the support of processing technology.
1. Product design stage. For the development of new models, especially new models, there are relatively few reference materials. At this time, the functional master model checking tool can help to quickly debug the work, especially when the early parts and equipment are unstable, it can be a reference. benchmark.
2. Product verification stage. At this stage, the functional master model inspection tool can also play a key role, especially in the first trial assembly stage of batch parts, many design confirmation work can be carried out on the master model inspection tool.
3. Trial production stage. The master model mold can link the digital prototype with the mass-produced model and various parts. In the trial production stage, the conflict between the body-in-white and the interior and exterior plastic parts is often unavoidable. The functional master model inspection tool can effectively determine the root of the problem, so as to guide the modification of unqualified parts, and point out the direction for product quality improvement.
4. After the standard operating procedure, the mass production stage. The main model inspection tool can also be used in the daily quality control of parts and problem analysis, especially when the quality of the product fluctuates, whether it is the quality fluctuation of the body, the deviation of the interior and exterior parts, or the gradual change of the two, which accumulates. Yes, all can be analyzed using the main model checker.
So what are the specific characteristics of automobile inspection tool processing technology? Based on years of industry experience, the editor of the automotive inspection tool manufacturer will work with you to further understand it.
Inspection of car inspection tool holes, many main holes and flanges in body stamping parts are independently inspected. In the design of the inspection tool, a boss with a thickness of about 1mm is usually added on the surface of the inspection surface. The base of the boss and the base of the workpiece hole are on the same axis, and the diameter is 5mm larger than the hole diameter, and the double-scribing method is used on the boss. Inspection of. When the accuracy requirements of the measured hole are relatively high, the method of positioning the hole is selected to be checked with a plug gauge and a bushing.
Regarding the design of the base plate assembly of the car inspection tool, the surface is stretched a certain distance along the direction of the reference plane on the inspection surface, so that the thickness of the lowest point is greater than 150mm, so as to ensure that the inspection device has sufficient strength, and at the same time, try to make the inspection surface as low as possible. That is, the upper surface (base surface) of the base plate assembly is at the integer position of the body coordinate system. The inspection floor assembly is generally composed of a base plate, a channel steel (if necessary, a steel beam is processed in the middle), a positioning block and a universal wheel. After the base plate is fixed by the inspection body, the other components can be selected according to the actual situation. Standard type.
In the process of mold manufacturing, trimming and punching processes have always been difficult points in the mold manufacturing process, especially for some large car molds with complex structures such as bevel cutting, oblique punching, and oblique turning. The determination of the trimming line is not simple if the traditional manufacturing method is used, and it needs to be repeatedly explored several times or even ten times, which brings a great workload to the fitter and processing equipment, and not only puts forward a higher level of skill for the fitter. requirements, and will seriously affect the debugging of the post-process mold. In fact, there are many trimming and punching dies that use alloy steel for their cutting edge materials in terms of cost. If the traditional trimming die manufacturing method is used, the cutting edge will inevitably be surfacing many times, because the material is repeatedly processed. In the process of surfacing welding, the inserts are easily cracked and the inserts are invalid, and they have to be reprocessed from scratch, so not only the cycle will be delayed, but also the manufacturing cost of the mold will be greatly increased.
If the laser cutting technology is used, for the developed car parts, after the drawing pattern is successfully tested, the laser cutting can be used to replace the trimming and punching processes, and the cutting is carried out along the trimming line of the car inspection tool. The obtained sample is directly used for the next flanging process to test the mold, and the final sample obtained is compared with the inspection tool. If there is a difference, the previous trimming line is trimmed and cut again by the computer until it is successful. The whole process saves two processes, completely changes the traditional single-line serial manufacturing method, greatly shortens the process flow and reduces the cost of mold manufacturing.
