Abstract
The utility model relates to a ram transmission mechanism for a vertical lathe, belonging to the field of vertical lathe machinery. The ram transmission mechanism comprises a rotary sliding seat; a ram capable of moving upwards and downwards is arranged on the rotary sliding seat; a screw nut is fixedly arranged on the rotary sliding seat; a screw matched with the screw nut is arranged corresponding to the screw nut; the screw is connected with the ram through a bearing seat; the bearing seat is fixed on the ram; and a bracket is arranged on the ram. The ram transmission mechanism is characterized in that a planetary gear reducer, corresponding to the screw, is fixedly arranged on the bracket; the output end of the planetary gear reducer is connected with the screw through a shaft coupler; and a servo motor is arranged corresponding to the planetary gear reducer. The ram transmission mechanism provided by the utility model has the advantages of simple structure, and convenience for operation and maintenance. Owing to the arrangement of the servo motor, the planetary gear reducer and the shaft coupler, the ram transmission mechanism has the characteristics of stability for running, high efficiency and capabilities of enlarging the rotating speed range and increasing the rotating torque.
Description
Technical field
The utility model relates to a kind of vertical lathe ram transmission mechanism that is used for, and belongs to the vertical lathe mechanical field.
Background technology
Vertical lathe is applicable to thick, the fine finishining of processing various ferrous metal, non-ferrous metal and part non-metal workpiece.On lathe, can carry out processing such as inside and outside circle cylinder, the inside and outside circle conical surface, end face and groove.When ram moved up and down, traditional transmission device adopted AC induction motor to drive gearbox usually, drives leading screw and on feed screw nut, rotates; Thereby accomplish moving up and down of ram; This kind type of drive complex structure and trouble point are many, and maintenance difficulty is big, make troubles to process.
The utility model content
The purpose of the utility model is to provide a kind of vertical lathe ram transmission mechanism that is used for, and is simple in structure, and operation and maintaining are convenient.
The described vertical lathe ram transmission mechanism that is used for of the utility model comprises rotary slide base, and the ram that moves up and down is installed on the rotary slide base; Be set with feed screw nut on the rotary slide base; Corresponding feed screw nut is provided with the leading screw that is complementary with it, and leading screw connects with ram through bearing block, and bearing block is fixed on the ram; Ram is provided with support; It is characterized in that: corresponding leading screw is installed with planetary reducer on support, and the planetary reducer output connects with leading screw through shaft coupling, and corresponding planetary reducer is provided with servomotor.
Servomotor can obtain motor from 0 to all rotating speeds the rated speed through pulse signal, can improve the rotating speed of motor scope; Through the output speed that planetary reducer can reduce motor is set; Improve torque; Planetary reducer compact conformation, volume and quality are little, gear range is big, efficient is high, running is steady, noise is low, and can reduce driving-chain, maintain easily and maintain; Adopt shaft coupling to connect leading screw and planetary reducer, its compact conformation, reliable operation and efficient are high.
Wherein, said shaft coupling adopts positive coupling.Adopt positive coupling, it is simple in structure, and is economical and practical.
Compared with prior art, the utlity model has following beneficial effect:
Through the utility model, it is simple in structure, and operation and maintaining are convenient.Owing to be provided with servomotor, planetary reducer and shaft coupling, enlarged the range of speeds, improved torque, and running is steadily, efficient is high.
Description of drawings

Among the figure: 1, servomotor 2, planetary reducer 3, support 4, positive coupling 5, bearing block 6, ram 7, slide 8, rotary slide base 9, feed screw nut 10, leading screw.
The specific embodiment
Below in conjunction with the embodiment accompanying drawing the utility model is further specified.
As shown in Figure 1, be used for vertical lathe ram transmission mechanism, comprise rotary slide base 8; The ram 6 that moves up and down is installed on the rotary slide base 8, is set with feed screw nut 9 on the rotary slide base 8, corresponding feed screw nut 9 is provided with the leading screw 10 that is complementary with it; Leading screw 10 connects with ram 6 through bearing block 5; Bearing block 5 is fixed on the ram 6, and ram 6 is provided with support 3, and corresponding leading screw 10 is installed with planetary reducer 2 on support 3; Planetary reducer 2 outputs connect with leading screw 10 through shaft coupling, and corresponding planetary reducer 2 is provided with servomotor 1.
In the present embodiment, said shaft coupling adopts positive coupling 4, can also adopt flexible coupling.
During use, earlier rotary slide base 8 is fixedly mounted on the slide 7.During work; Start servomotor 1, servomotor 1 drives planetary reducer 2 and rotates, planetary reducer 2 reductions of speed and improve torque after; Power is passed to leading screw 10 through positive coupling 4; Leading screw 10 rotates in feed screw nut 9, and leading screw is moved up and down, thereby accomplishes moving up and down of ram 6.
