CJ4 high-efficiency work fixture is really easy to use

At the beginning of April, we participated in the CJ4 high-efficiency fixture training class organized by the editorial department of Mechanical Workers. Purchased 4 sets of CJ4 high-efficiency work fixtures, after two months of actual use, proved to be really easy to use. For example: drill a hole of φ12mm on the 1Cr18Ni9Ti stainless steel, the depth is 20mm. In the past, only 150 holes can be drilled per shift.

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.

(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.
