Clamping and processing of large-sized workpieces

2022-09-02 10:07:00
Our factory encountered the problem of clamping when processing the saddle joint surface of the new product CA6250B saddle lathe 2m bed. Due to the equipment conditions of our factory, the processing of the saddle joint surface is only arranged on the BQ1012A gantry planer. The bed is shown in Figure 1. The bed weighs 1080kg and has a total length of 3.34m. The saddle joint surface is 0.69~1m away from the bed, that is, the surface to be machined is at the end of the bed. The minimum distance from the bottom of the bed to the support surface of the middle leg is 1.09m. , more than 1m width of the planer table. This heavy and long bed is extremely difficult to balance across the workbench and is difficult to clamp. To this end, I designed a special fixture for large-plate positioning support to solve the problem of machining clamping.

Mini Steel Tape Measure

1. Features of tape measure

Gift rulers are used for advertising and promotion. They are divided into Steel tape (steel tape) and leather tape (PVC plastic fiber tape). They are usually cute and compact. Tape measures are also called measuring tools. Eighty-five percent of the world's tape measures are exported from China.

2, the characteristics of the tape measure

(1) The tape measure is too deformed and will not fail

Why didn't it fail? The spring in the tape measure is very long, and its range from completely relaxed to fully tightened is very large. The entire stroke of the tape measure includes it, and there is a margin at both ends, so the tape measure will not fail.

(2) Pull one meter long and pull two meters long, there is no difference in tension

The spring of the tape measure is very thin, and the amount of deformation when it is tightened is also small, so the reaction force is very small, and the force change is not felt when the rule is pulled.
