Description

Manipulator clamping jaw component and pressure quenching transfer tool

Technical Field

The disclosure relates to the field of engineering machinery, in particular to a manipulator clamping jaw component and a pressure quenching transfer tool.

Background

The pressure quenching is a process of secondarily heating the workpiece in a rotary hearth furnace and then transferring the high-temperature workpiece to pressure quenching equipment for limited quenching in a manual or mechanical transfer mode. For mechanically transferred gear ring parts, the transfer is relatively simple due to the light weight of the gear ring parts; however, for gear parts, the self weight of the gear is not only considered, but also the tooth top part of the gear is required to be prevented from being crushed in the transferring process. The transportation link of pressure quenching in-process generally divide into artifical transportation or supplementary manipulator transportation, along with the increase of the production line automation degree of pressure quenching, adopts reheat rotary hearth furnace, transport mechanism, pressure quenching lathe, cleaning equipment, cryogenic tempering and air cooling device's doubling to handle usually, consequently, supplementary manipulator transports becomes the tendency of making a big trend. Transport the frock and be responsible for shifting the work piece of high temperature attitude to the pressure equipment of quenching fast, reasonable transportation frock needs to possess following several requirements: (1) the grabbing is firm, safe and reliable during high-speed transportation, and the risk of falling parts is avoided; (2) the mechanical arm has certain protection measures, and the outer wall of the gear ring and the top of the gear tooth are not damaged by pressure after the mechanical arm is transferred; (3) the manipulator commonality is strong.

The pressure quenching products are mainly divided into two categories of gear rings, gears and the like, and the pressure quenching products are mainly characterized in that workpieces are heavy in weight and large in diameter size span, and meanwhile, the metallographic structure of the products is strict, so that the transfer process period is required to be short, namely the transfer speed is high. In the field production, the problems of part falling and tooth top crushing often occur when the original equipment manufacturer carries out the transfer of gear parts, the product quality is seriously influenced, and the huge waste of workshops is caused. Through in-depth analysis, the existing clamping jaw is mainly in line contact with a workpiece, even in point contact under extreme conditions during transferring and shaking, and the contact area between the clamping jaw and the workpiece is relatively small, so that the friction force is not enough to offset the self weight of the workpiece in the transferring process, and the workpiece is easy to drop and grab; meanwhile, because the contact area is small, and the sharp corner part of the clamping jaw of the mechanical arm is in contact with the tooth top part, under the action of instant clamping force, the tooth top can be crushed, and finally the product is scrapped.
