According to the utility model, by the arrangement of the change gears between the servo motor and the machine tool spindle for drive, the gear transfer under different torques from the servo motor to the spindle is implemented, the processing application range of the machine tool is widened, the stiffness of equipment is improved, the non-fault time of the equipment is prolonged and the processing energy consumption of a product is also reduced.
Description
Technical field
The utility model relates to vertical machine, particularly the spindle drive of vertical machine.
Background technology
The machine tool chief axis mechanism that uses in the prior art at present is generally: servomotor passes to main shaft to moment of torsion through synchronous band transmission, thereby drives main axis rotation.The moment of torsion that common this structure is transmitted is less, is not suitable for heavy cut processing, and the service life of band is also shorter relatively synchronously.
The utility model content
The utility model is in order to overcome defective in the above-mentioned prior art; Can realize the gear transmission of the different moments of torsion of servomotor to main shaft; Widened the processing scope of application of lathe, increased the rigidity of equipment, the failure free time that has effectively prolonged equipment has reduced the product power consumption of polymer processing simultaneously.
For realizing above-mentioned purpose, the utility model provides a kind of spindle drive of vertical machine, comprising: servomotor, and its output is provided with output gear; Machine tool chief axis, it is provided with a plurality of to the gear different rotating speeds requirement, that have the different numbers of teeth; Speed change intermediate gear; It is located between said servomotor output gear and the machine tool chief axis gear; The gear quantity of the quantity of speed change intermediate gear and said machine tool chief axis is suitable; Any speed change intermediate gear meshes with corresponding machine tool chief axis gear selectivity under the driving of speed change oil cylinder, realizes the torque drive of servomotor and machine tool chief axis.
Wherein, The speed change oil cylinder drives speed change intermediate gear and the engagement of machine tool chief axis gear selectivity through selector fork; The axial drive rod of speed change oil cylinder and the parallel axes of speed change intermediate gear, selector fork two ends respectively with speed change hydraulic oil cylinder driving bar and speed change intermediate gear the axle socket-connect.
Compared with prior art, the utlity model has following beneficial effect:
1, through the gear transmission of different moments of torsion between servomotor to the machine tool chief axis, realized that lathe more has wideer processing torque range, applicability strengthens;
2, increase the rigidity of equipment, avoided synchronous band to transmit the equipment insufficient rigidity that moment of torsion causes, helped the machining accuracy of support equipment;
3, prolong the accident-free duration of equipment, realized the long-time stable processing of product, reduced the appearance of substandard products;
4, transmission efficiency obtains increase to a certain degree, has reduced the energy consumption of product processing.
Description of drawings
Fig. 1 is the right parallax stereogram of the spindle drive of the utility model vertical machine;
Fig. 2 is the left parallax stereogram of the spindle drive of the utility model vertical machine.
In conjunction with the accompanying drawing following Reference numeral of mark above that:
The 1-main shaft, 11-main shaft low-speed gear, 12-main shaft high gear, 2-tool changing oil cylinder, 3-speed change oil cylinder, 31-shift fork, 32-high speed idler gear, 33-low speed idler gear, 34-drive rod, 4-servomotor, 41-output gear.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of the specific embodiment.
The spindle drive of the vertical machine of the utility model comprises servomotor 4 and machine tool chief axis 1 shown in Fig. 1-2, the top axial of machine tool chief axis is connected with tool changing oil cylinder 2, the switching of tool changing oil cylinder 2 driving main shaft cutters.The output of servomotor 4 is provided with an output gear 41; Machine tool chief axis 1 is provided with two to the main shaft low-speed gear 11 different rotating speeds requirement, that have the different numbers of teeth and main shaft high gear 12, and main shaft low-speed gear 11 is 2: 1 with the gear ratio of main shaft high gear 12; Between servomotor 4 and main shaft 1, two associated movement, corresponding different main gear only low speed idler gear 33 and high speed idler gears 32 are set, low speed idler gear 33 is 1: 2 with the gear ratio of high speed idler gear 32.The speed change intermediate gear mass motion also receives the driving of speed change oil cylinder 3; Main shaft high gear 12 and middle high gear 32 engagements when main shaft is in high rotating speed; Main shaft low-speed gear and middle low-speed gear break away from; Main shaft low-speed gear 11 meshes with middle low-speed gear 31 when main shaft is in the slow-speed of revolution in addition, and main shaft high gear and middle high gear break away from.
Further shown in Fig. 1-2; Speed change oil cylinder 3 drives idler gear through selector fork 31 and mainshaft gear is realized the selectivity engagement; The axial drive rod 34 of speed change oil cylinder 3 and the parallel axes of idler gear, selector fork 31 two ends respectively with spool the socket-connecting of speed change hydraulic oil cylinder driving bar and idler gear.When main shaft needed high rotating speed, speed change oil cylinder 3 drove selector forks and then makes main shaft high gear 12 and 32 engagements of high speed idler gear, and this moment, main shaft low-speed gear 11 broke away from low speed idler gear 33; When main shaft needed the slow-speed of revolution, speed change oil cylinder 3 drove selector fork and then makes main shaft low- speed gear 11 and 33 engagements of low speed idler gear, and this moment, main shaft high gear 12 broke away from high speed idler gear 32, thereby realized the spindle that different rotating speeds requires.
The utility model has realized that through the gear transmission of different moments of torsion between servomotor to the main shaft lathe has wideer processing torque range, and applicability strengthens; Increase the rigidity of equipment, avoided synchronous band to transmit the equipment insufficient rigidity that moment of torsion causes, helped the machining accuracy of support equipment; Prolong the accident-free duration of equipment, realized the long-time stable processing of product, reduced the appearance of substandard products; Transmission efficiency obtains increase to a certain degree, has reduced the energy consumption of product processing.
More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
