Gear grinding machine

Abstract

The invention discloses a gear grinding machine comprising a machine body, a second rotating shaft box body, a sliding table and a cooling oil tank; the side wall of the machine body is provided withan X-axis guide rail; the second rotating shaft box body is slidably installed on the X-axis guide rail, and internally provided with a rotating shaft B; the tail end of the rotating shaft B is provided with a first rotating shaft box body which is internally provided with a workpiece spindle A, and the end of the workpiece spindle A is provided with a workpiece; the sliding table is movably installed on the machine body, and located above the second rotating shaft box body; the sliding table is provided with a third rotating shaft box body which is internally provided with a grinding wheel spindle C of which the lower end is provided with a grinding wheel; and the cooling oil tank is arranged below the first rotating shaft box body in the X-axis direction. Compared with a traditional structure, the gear grinding machine has the advantages that the three movable shafts are not stacked, and accordingly the removal and installation are simple and convenient; not only can the production efficiency be improved, but also the maintenance is convenient; the weight distribution is more reasonable, and the situation that the gear grinding machine is not top-heavy is avoided, so that the counterweight of the machine body can be further reduced; and the size of the machine is reduced.

Description

technical field

[0001] The invention belongs to the technical field of gear processing equipment, and in particular relates to a gear grinding machine. Background technique

[0002] In order to process the gear teeth of the spiral bevel gear, the gear grinding machine is equipped with a six-axis transmission mechanism, which specifically includes 3 rotating axes and 3 moving axes. The moving axes include the X, Y, and Z axes that realize the spatial movement adjustment of the grinding wheel and the workpiece. , the rotating shaft includes a workpiece rotating shaft, a grinding wheel rotating shaft and a pendulum shaft for adjusting the angle between the workpiece rotating shaft and the grinding wheel rotating shaft. In addition, the gear grinding machine also includes a grinding wheel dresser, so it is also called a seven-axis structure.

[0003] The gear grinding machines currently on the market mainly include a fuselage and a grinding wheel box and a workpiece box located...
