A quantitative oil supply device when producing gears in hobbing mode

Abstract

The invention discloses a quantitative oil supply device used when gears are produced in a hobbing manner. The quantitative oil supply device comprises a filling box. A transmission cavity is formed in the filling box, a putting cavity with a downward opening is formed in the inner wall of the lower end of the transmission cavity, and a spraying device for putting lubricant is arranged in the putting cavity. A suction nozzle structure capable of sliding along a hob edge is firstly arranged along a hob feeding path, a hob is subjected to attle removal, smooth cutting between the hob and a cutting part is guaranteed, the situation that burrs or pits exist is reduced, meanwhile, a mechanism capable of sliding left and right in a reciprocating manner cooperates with a lifting valve structure,the putting quantity is precisely controlled at the same movement distance and the same sliding time, and the problem that the lubricant is left in pipelines, so that the putting quantity precision isaffected does not exist.

Description

Technical field [0001] The present invention relates to the field of gear processing technology, in particular to a dosing device during oil production mode gear hobbing employed. Background technique [0002] The cutting process of the gear, hobbing as one of the most widely used process. Hobbing generating method using the principle of the method is to machine gears, thus, the need to protect the lubricating oil fed to the intermittent mode, each time re-engagement are required to form a film [0003] However, turning now supply structure comprising an oil pump and only the portion of the pipeline, to achieve intermittent oil supply pump via a control, however, due to the remaining within the conduit and not in time to prevent the oil flow, and also need to beware of the mechanical cutting the residue remaining on the hob, so that the cogging is generated surface pits or burrs. An apparatus capable of solving the above problems is illustrated by the present invention. Inventiv...

Problems solved by technology

[0003] However, the oil supply structure of the current lathe part only includes the oil pump and the oil pipeline. The intermittent oil supply work is realized by controlling the oil pump. However, the oil flow cannot be prevented in time due to the residue in the pipeline, and it is also necessary to beware of mechanical cutting. The slag remains on the hob, causing pits or burrs on the alveolar surface
