Greetings to all lovers of homemade products and those who just looked at the site in search of interesting ideas that you can take note of. Today I present to your attention a variant of the hydraulic jack modernization. The whole point is that the author replaced the lever that drives the chassis of the jack with a pedal. Someone might say that such a revision does not make sense, but it depends on which side you look at. It all depends on where and how the jack is used, the author uses his own for a homemade press, and here this revision is just convenient. In any case, I personally liked the idea, and I decided to describe it as a poet, but decide for yourself. If she hooked someone, please, sit down more comfortably, read, watch (as usual, at the bottom of the video) and take note.
* hydraulic jack,
* sheet metal 6-8 mm and 30 mm thick,
* hydraulic hose,
* bolts and nuts,
* some parts from the jack,
* will hurt (or something that can replace it),
* car oil,
* welding machine,
* drilling machine,
* thread tap,
* cutting disc machine,
* gas torch,
* magnetic squares for welding,
* marking tool.
First, the author takes the jack and disassembles it completely , to the very foundation. See the sequence from the photo.
Then the author cuts off the base with a grinder. Next, he drills holes with a drill, as shown in the photo. In one, he cuts a thread and screw a fitting into it.
After the author assembles the jack in the reverse order.
At this stage, the author starts making the pedal base. It will be in two parts. While collecting the first one. To do this, he cuts out the necessary parts from sheet metal 6 mm thick (maybe a little thicker, it's so difficult to determine). All of them are shown in the photo.
Now let's proceed to the second part. Its author was made of solid sheet steel, if I am not mistaken, the thickness is about 30 mm. First, the author gave the blank the same shape as the lower part, but this part is smaller.
Then the author puts the markup on it as shown in the photo. Drills holes according to marks and cuts a thread in them with a tap. The author welds a nut over two holes on the plane.
Then the smaller part is removed, the larger one is burned from the inside by the burner , in order to keep the nutria dry (it is necessary to dry the remaining coolant after drilling).
After drying, the author again assembles both parts of the base, but already through the gasket, I don't know for sure what it is, it might hurt or something similar, just oil will be poured into the lower part, that's why a gasket is needed so that there is no leakage.
The author screws two such pins with holes into the holes on the smaller part, this side of the smaller part will adhere to the larger one.
Then, oil is poured into a large part, as I wrote above, and everything is assembled through a gasket on the bolts. The author throws a small ball into one of the holes, to be honest, I'm not good at hydraulics and I don't know what it is for, maybe someone will tell you in the comments)))
Next, the author screwed the piston from the jack into the nut. Then I picked up just such a detail, as shown in the photo. On a grinder, I corrected its end. Then I welded a small elongated nut to it, into which I then screwed a threaded rod.
< img class = "aligncenter" alt = "Jack with a pedal drive instead of a lever" src = "https://usamodelkina.ru/uploads/posts/2021-08/1629745881_68.jpg"/> After the author drilled a hole in the nut and installed such a detail in it, somewhat similar to a tube with a cut along the entire length .
Then the author carved a roller out of the round timber, drilled a blind hole in it on one side, cut a thread in it and screwed into it a previously prepared part. Looking ahead, I will say that this part is necessary to relieve pressure. He screws it into the upper part of the base.
Now you need to mount the pedal itself directly. < br>To do this, the author cuts off a small square from the metal strip. Then disassembles the lever installation mechanism. He only needed two plates from him. All this must be installed on top of the base. First, the author connects the parts and drills a hole in the square. Then, using a square, he welds the square into place. It fixes the plates on it through the cotter pin. He takes a ready-made pedal. How it was made, I think it makes no sense to describe, here everything is clear. Attaches the pedal to the base through plates and a spring, as shown in the photo.
Now it remains to secure the hydraulic hose. First, the author screws it to the base. Process in the photo. Then he pumps the pedal, the oil enters the hose, then everything works, and the hose can be connected to the jack, which the author does. That's the whole upgrade.
At the final stage, the author checks the equipment, first in idle mode, then on the press. Everything works fine.
About the relevance of this idea you can write in the comments, the opinion is very interesting. And on this I say goodbye to you, good luck to everyone and see you again at Samodelkin's !!!!
