The flat milling head in gantry machining center right angle
Technical field
The utility model belongs to the stock-removing machine part field, and is especially relevant with the flat milling head in a kind of gantry machining center right angle.
Background technology
The flat milling head in right angle is to utilize machine tool chief axis power, is installed in the isolated plant that on the main shaft of lathe some narrow and small zones of workpiece is carried out Milling Process.The mainshaft mechanism of existing angle milling head directly is connected with bindiny mechanism, because bindiny mechanism's appearance and size is relatively big, makes the mainshaft mechanism of milling head can't stretch in the small space such as slot and processes, and has limited the range of work of lathe.
The utility model content
The purpose of this utility model is exactly to overcome the defective that can't adapt to the processing in the small space that existing angle milling head exists, and a kind of flat milling head in gantry machining center right angle that can adapt to small space processing is provided.For this reason, the utility model is by the following technical solutions:
The flat milling head in gantry machining center right angle, comprise bindiny mechanism and mainshaft mechanism, bindiny mechanism comprises connect box, the bevel gear of vertical power transmission shaft and hollow, bevel gear passes through bearing, bearing block is installed on the connect box interior walls, vertical power transmission shaft is plugged in the bevel gear hollow cavity and forms spline fitted that to carry out circumferencial direction spacing, make vertical power transmission shaft endwisely slip and can not relatively rotate at the bevel gear hollow cavity, mainshaft mechanism comprises the main shaft casing, the milling head main shaft, the milling head main shaft is horizontally installed in the main shaft casing by bearings, it is characterized in that: the flat milling head in described right angle also comprises transmission mechanism, transmission mechanism comprises the thin-and-long transmission case body, many lateral shafts and be arranged at spiral bevel gear in the transmission case body, spur gear, travelling gear, lateral shaft is fixedly installed in transmission case body, the transmission case body upper end is connected with described connect box, the transmission case body lower end is connected with described main shaft casing, transmission case body, the inner chamber of connect box and main shaft casing connects, lateral shaft near bindiny mechanism is first lateral shaft, spiral bevel gear is loaded on first lateral shaft by the first needle roller roller combination bearing radial-axial support set, spiral bevel gear and described bevel gear are meshing with each other, spur gear is set in first lateral shaft and interfixes with spiral bevel gear, travelling gear is loaded on lateral shaft by needle roller roller combination bearing radial-axial support set, travelling gear and spur gear engagement, engagement successively between a plurality of travelling gears, fixed cover is equipped with gear on the described milling head main shaft, this gear and travelling gear engagement.
When the utility model uses, bindiny mechanism mounts in lathe headstock by secondary blind rivet, vertical power transmission shaft is connected with machine tool chief axis by the main blind rivet that is mounted thereon, the machine tool chief axis rotation drives the power transmission shaft rotation, the power transmission shaft rotation drives the spur gear rotation by meshed bevel gears and spiral bevel gear transmission, the spur gear rotation drives the milling head main axis rotation by the travelling gear transmission of engagement successively, carries out machining thereby drive the cutter rotation that is installed on the milling head main shaft.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Described spiral bevel gear is provided with sleeve, and described spur gear fixed cover is loaded on this sleeve.
Use the utility model can reach following beneficial effect: by increasing long and narrow transmission mechanism, to make milling head can stretch into small space, adapt to processing in the small space.
