Description
Technical field
The present invention relates to gear rolling machine tool technology fields, and in particular to a kind of horizontal gear rolling machine.
Background technique
Horizontal gear rolling machine is a kind of straight-tooth dedicated on various parts, helical teeth, oblique spline gear, oil groove, screw thread, snail
The processing of bar, straight grain, by the two gear rolling molds opposite to each other up and down being mounted on slide unit, by oil after synchronized gear synchronous
Linear relative movement is made in pressure or servo motor driving, and mold is grinding into the tooth form gradually cut, workpiece by the top support in front and back,
And work pieces process position can be easily adjusted by the top displacement function in front and back, the rotation of upper/lower die relative movement drives workpiece
Turn and gradually by workpiece extrusion molding, finally exited after shaped.
In the prior art, it in order to guarantee the synchronization of upper and lower gear rolling mold movement, needs to be arranged on upper and lower gear rolling device same
Rack gear is walked, synchromesh gear is set between synchronous rack gear up and down, to guarantee the synchronization of gear rolling up and down.
Summary of the invention
The technical problem to be solved by the present invention is to：Cancel synchromesh gear and synchronous rack structure, makes horizontal gear rolling machine knot
Structure is simpler, but does not reduce processing quality.
The technical solution adopted by the present invention is that：A kind of horizontal gear rolling machine, including lathe bed, preceding top and rear top, rack
Upper rail and lower guideway are inside respectively set one on the other, upper slide unit moves on upper rail, and lower slide unit moves on lower guideway, on
Spline tooth broaching board is installed on the dress blade insert of slide unit, spline tooth broaching board is installed on the dress blade insert of lower slide unit；It is fixedly connected on the inside of upper slide unit
Upper screw rod pair is fixedly connected with lower screw pair on the inside of lower slide unit, be further fixed on lathe bed motor, upper screw rod, lower motor and under
Screw rod, wherein upper screw rod pair covers on upper screw rod, and upper screw rod connects upper motor, and lower screw pair covers on lower screw rod, and lower screw rod connects
Connect lower motor；The upper screw rod and lower screw rod are hollow structure, and the hollow cavity both ends of upper screw rod and lower screw rod are connected to
Oil cooled system system, the upper motor and lower motor are connected to digital control system and are accurately controlled by system.
Further, the upper screw rod and lower screw rod move synchronously.
Further, oil cooled system system is oil cooling machine, and the temperature probe of oil cooling machine is set to upper leading screw and lower leading screw
On outer surface.
The beneficial effects of the invention are as follows：
（1）Structure is simple, and not with rack-and-pinion come synchronous, what is leaned on is the synchronous fortune of two screw rod of system drive for upper screw rod and lower screw rod
It is dynamic, required synchronous rack gear-synchronous gear structure in the horizontal gear rolling machine of tradition is eliminated, synchronous rack gear-synchromesh gear has been lacked
Between abrasion, make maintenance of equipment and safeguard it is more convenient.
（2）The rotation of screw rod is accurately controlled by motor, screw rod uses hollow structure, has refrigerating function, can be realized
Accurate control of the motor to gear rolling mold, machining accuracy are low unlike the horizontal gear rolling machine of tradition；In addition, due to not having to consider to synchronize
The abrasion of gear is processed more stable.
（3）The surface temperature of screw rod is monitored, and pass to by the present invention by being further improved by temperature probe
On the one hand oil cooling machine can accurately monitor screw rod temperature, on the other hand, adjust separately screw rod temperature up and down by controlling cooling oil
Degree is more nearly the two, then further increases equipment precision.
