A snap spring assembling tool comprises a feeding opening, a cone sleeve having an annular cover connected with the back end thereof, a core shaft passing through the annular cover and disposed in the cone sleeve, a notch on one end of the core shaft in the cone sleeve and an elastic unit disposed in the notch in the core shaft. The elastic unit comprises two moveable blocks, two springs, connecting boards and two bolts. The two moveable blocks are oppositely disposed and are respectively provided with slots, the positions of which are corresponding to each other, and a blind hole at two sides of the slot. The two ends of the spring are disposed in the blind holes corresponding to the two moveable blocks. Two bolts are respectively connected with the core shaft after passing through the connecting boards and a slot. One end outside of the cone sleeve is connected with a pressing handle. By using the invention, the manufacturing efficiency for a snap spring assembly is greatly promoted, the working intensity is obviously decreased and the defective products are efficiently decreased.
Description
technical field [0001] The invention belongs to hand tools specially suitable for assembling deformed parts, and relates to a clamp spring assembling tool. It is suitable as a special hand tool for installing the circlip into the circlip groove of the parts (such as the piston of the engine, etc.). Background technique [0002] During the production and assembly process of the engine, it is necessary to install the circlip into the circlip groove of the piston of the engine. In the prior art, the operator generally places the circlip on the groove first, and then installs it into the circlip groove with a changer . Because the circlip is thin and its diameter is relatively large, it is difficult for the operator to grasp the strength when assembling it manually, which is inconvenient to assemble, easily damages the circlip groove, and the assembly efficiency is very low. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvanta...
