Take a look at the "black technology" 55 on the device----Inspection of the "Universal Clamp"”

Inspection and maintenance work is inseparable from the "bench vise" used to fix and repair workpieces. Although the bench vise has strong applicability, it also has some disadvantages. For example, when repairing some heavy workpieces, they have to be hauled back from the site by trolley, which is time-consuming and labor-intensive. ； Some small workpieces with irregular shapes are not securely fixed and even need to be pressed hard with hands. However, the workpieces are still prone to "deviation" during operation, which not only affects the repair accuracy, but also easily injures the hands. Are there any lightweight and flexible tools that can solve the disadvantages of a bench vise? It’s better not to spend any money :lol

Case: Master Li Zengyi, the fitter squad leader of Daqing Petrochemical Maintenance Workshop (like! ) made a set of small and convenient fixing tools using scrap steel pipes, steel plates, bolts, etc. Use a small section of channel steel and a small piece of hexagonal steel plate, drill a hole in each of the channel steel and hexagonal steel plate, and use discarded screws to thread and tighten them to form the fixture.

Then, he made a complex fixed bracket, which included spacer sleeves, cross-shaped connectors, optical shaft clamps, locking bolts, etc. Each of these structures has its uses: By replacing sleeves of different lengths, the height and position of the clamp can be adjusted ； By adjusting the locking bolt, the clamp can be rotated at will... These are all made by hand using scrap materials he picked up and did not cost a penny.

“After the production of "Universal Clamp" was completed, Master Li began to "test his skills". He found an anti-static copper rod with burrs, and by rotating the handle, he clamped the copper rod tightly to the end face of the hexagonal steel plate and the bottom of the channel steel. Because of the uniform force, the copper rod was ground smooth and flat. In the past, everyone had to hold a copper rod in one hand and a file to sharpen it. Now, the "universal clamp" can not only firmly fix the workpiece, but also allow the workpiece to rotate 360 ​​degrees at will. When working, the fitters no longer have to assume the uncomfortable posture of "groveling" according to the angle of the workpiece. What's even more convenient is that because the workpiece is small, you can even take it directly to the site to carry out work, truly realizing "freedom of maintenance"!

Innovative intentions can create miracles in many places
