Description
Technical field
The utility model relates to press-loading device, particularly relates to a kind of servo press.
Background technology
Along with assembling, the improving constantly of manufacturing fast development and living standard, the quality requirement of people to product improves constantly, thus has higher requirement to process and assemble product.For the assembling of a lot of key components and parts of bearing, screw, engine stretching wheel etc., not only require the assembly force controlling result, and requirement is controlled, so propose requirements at the higher level to assembly equipment to the power of assembling process and displacement.
In the past, press-fiting of press-loading device realized primarily of pneumatic cylinder or hydraulic cylinder, and the problem that this mode is brought is: pressure assembling force changes along with the change of air pressure and hydraulic pressures, but the accurate control of air pressure and hydraulic pressures is more difficult and cost is very high; In addition, the elasticity of Compressed Gas and the response lag of hydraulic system all cause press-fiting position and cannot accurately control.For solving the problem, the existing servo press that adopts press-fits at present.
Servo press is generally divided into associated mode and parallel-axis type.The gearratio of direct-coupled type servo press is more accurate, but physical dimension is not compact; Parallel-axis type servo press adopts toothed belt transmission to connect line shaft and transmission main shaft, compact dimensions, but transmission is inaccurate.Therefore, also need to further improve servo press.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of servo press simultaneously possessing transmission precision and compact dimensions advantage.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of servo press, comprise servomotor, planetary roller screw assembly, piston rod and pressure sensor, be connected by a reductor between described servomotor with described planetary roller screw component, the output shaft of described servomotor and the power shaft direct connection of described reductor, the power transmission shaft direct connection in the output shaft of described reductor and described planetary roller screw assembly.
Preferably, described reductor is parallel helical speed reduction gear, and its gear adopted is precise finiss helical gear.
Preferably, the gear pair engagement of described reductor adopts low back clearance mode.
Preferably, the output shaft of described reductor and power shaft are hollow shaft.
Preferably, the power transmission shaft in described planetary roller screw assembly is planetary roller screw axis.
Preferably, described reductor is also integrated with a set of auto-jet lubrication device, described auto-jet lubrication device comprises self-priming gear oil pump, and power is passed to described self-priming gear oil pump through an one-way driving mechanism by the output shaft of described reductor.

Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is the front view of a kind of servo press disclosed in the utility model embodiment;
Fig. 2 is the enlarged diagram at A place in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Servo press shown in Fig. 1 and 2 comprises servomotor 1, planetary roller screw assembly 2, piston rod 3 and pressure sensor 4, and pressure sensor 4 is arranged in planetary roller screw assembly 2.Planetary roller screw assembly 2 comprises planetary roller screw axis 2a(hereinafter referred to as main shaft) and planetary roller feed screw nut 2b(hereinafter referred to as nut), nut is connected with a lubrication assembly 2d; Main shaft is the primary drive axle of servo press, and convert rotational motion is the rectilinear motion of nut by accurate thread transmission by main shaft, and piston rod 3 is fixedly connected with nut, and piston rod 3 like this will be followed nut and be done rectilinear motion.The holder of main shaft is the angular contact ball bearing assembly 2c of one group of tandem general combo band pretension, bears axial pressure thus, and axial float is reduced to minimum degree.Bearing assembly is connected with pressure sensor 4, and the pressure of axis is directly fed back to pressure sensor 4, the precision that the axial push-pull power that this associated mode ensures detects.
A parallel helical speed reduction gear 5(is passed through hereinafter referred to as reductor between servomotor 1 with planetary roller screw component) connect, the output shaft of servomotor 1 and the power shaft 5a direct connection of reductor, the main shaft 2a direct connection in the output shaft 5b of reductor and planetary roller screw assembly 2.Output shaft and the power shaft of reductor are hollow shaft.Reductor adopts 2 grades of transmissions, power by motor output shaft and reductor power shaft direct connection, after 2 grades of transmissions, the output shaft of reductor by with main shaft direct connection, power and motion are finally passed to main shaft.Driven by servomotor reductor power shaft and output shaft rotation, drive main axis, and this moved through the reciprocating motion that planetary roller screw assembly 2 is converted into piston rod 3.The gear that reductor adopts is precise finiss helical gear, has noise low, the features such as stable drive.Simultaneously gear pair engagement adopts low back clearance mode, because of the error that back clearance produces during to reduce reductor commutation, improves the transmission accuracy of whole mechanical system, improves the bulk life time (particularly gear teeth life-span) of reductor.
Reductor is also integrated with a set of auto-jet lubrication device 6, auto-jet lubrication device comprises self-priming gear oil pump 6a, and the power source of lubricating arrangement is the output shaft of reductor, and power is passed to self-priming gear oil pump through an one-way driving mechanism 7 by output shaft.Adopting the object of one-way driving mechanism to ensure there is not the reversal that inlet port and jet occur because of the positive decommuntation of reductor in self-priming gear oil pump.Auto-jet lubrication device ensure that the lubrication of gear teeth transmission is abundant, improves the life-span of gear, also reduces the deceleration box temperature of reductor under heavy duty/high-speed case simultaneously, avoid because system heats up and produce adverse consequences.
Compared with prior art, the beneficial effects of the utility model are: the precision parallel Helical gear Transmission being replaced by particular design by the toothed belt transmission adopted by parallel-axis type, precision parallel Helical gear Transmission and servo press become one, transmission precision, servo press appearance and size is less, more aobvious structure compact, more applicable required precisions are high, simultaneously to the conditional occasion of installation dimension.
To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
