The spherical bearing tool has a large bearing size and high precision, and the finishing after heat treatment is also completed by the tooling. The machining of the spherical surface by the general profiling method is difficult to ensure. Therefore, the tooling uses a forming method to machine the spherical surface, and uses a small knife holder on the lathe to clamp the cutter.
It is composed of a base, a turntable, a small tool holder, a transmission gear, a rack, a transmission connection device and the like.
In order to make the structure compact, the turntable of the whole tooling can be inserted into the gap between the machine tool and the chuck guide rail, which is lower than the outer diameter of the chuck by 5mm. During operation, the spindle of the machine tool rotates the workpiece, the longitudinal movement of the slide box, the push rod clamped on the large slide drives the rack feed, and the rack meshes with the gear fixed on the turntable, so that the turntable rotates around the center of rotation. The car goes out of the way.
The turntable, base and swivel sleeve shall be made of cast iron to prevent burns on the rail surface and the slewing bearing surface during operation. The base taper surface and the guide rail surface should be matched with the turntable to ensure good contact and reduce the amount of scraping. The design uses the V-shaped guide surface of the bed and the V-shaped guide surface of the tailstock to position the tooling, and the flat guide surface is not in contact.
After the processing is completed, it is assembled on the bed to check whether the tooling rotation center coincides with the spindle rotation center line, and the error is within 15, so if the tolerance is corresponding to the side of the V-shaped guide. After scraping, it is researched with the base to ensure good contact with the mating surface. The contact point is more than 5 points per square centimeter, and the annular guide is also in contact when the taper surface is required to contact.

Suspended platform, as temporary suspended cradle platform, are widely applied in maintenance applications such as curtain fecade cleaning in high rise building, painting, glazing repairs, bill- board painting, cable installation and other outer working of high rise building up to 150 meters about 30 floors high. Our ZLP series suspended platform cradle, ZLP1000, ZLP800, ZLP630, ZLP500, ZLP400 and ZLP150, are good choices for fulfill above outside of wall work. Based on the different materials, the suspended platform could be divided into Aluminum Working Platform, steel Working Platform, galvanized Working Platform.
ZLP series temporarily installed suspended platform is an ideal access equipment for building facade construction, decoration, cleaning and maintenance. It can be also applied to other aerial working such as elevator installing, ship building, construction of dam, bridge, large chimney, etc.
This equipment is easy to operate, convenient to move and reliable in safety and much more efficient than traditional scaffolding.
