Abstract
The utility model relates to a main shaft variable speed gear of a vertical lathe and belongs to the field of lathe equipment. The main shaft variable speed gear of a vertical lathe comprises a variable frequency motor, a belt pulley transmission mechanism and a two-gear transmission case, wherein the output shaft of the variable frequency motor is connected with the input shaft of the two-gear transmission case through the belt pulley transmission mechanism, and the output shaft of the two-gear transmission case is connected with the main shaft through the belt pulley transmission mechanism. The main shaft variable speed gear of vertical lathe has a simple and compact structure and utilizes the variable frequency motor to change the output rotating speed of the motor by changing the frequency so as to fit for frequent change under different working conditions; and the two-gear transmission case greatly shortens a transmission chain, simplifies the transmission process, reduces the failure point and guarantees convenient repair and maintenance.
Description
Technical field
The utility model relates to a kind of main shaft speed change device of vertical lathe, belongs to field of machine tool equipment.
Background technology
Vertical lathe is applicable to that high-speed steel tool and hard alloy cutter process thick, the fine finishining of various ferrous metal, non-ferrous metal and part non-metal workpiece, on lathe, can carry out the processing of inside and outside circle cylinder, end face, the inside and outside circle conical surface and groove and cut-out etc.Traditional vertical lathe is driven by three-phase AC asynchronous motor (1470r/min) usually, gives gearbox through pulley transmission mechanism with transmission of power then, makes main shaft obtain 16 grades of rotating speeds through the multi-stage gear transmission in the gearbox, realizes the speed governing of main shaft.But this gear shift mode transmission is complicated, and the transmission parts are many, increased the trouble point of speed change gear greatly, brings very big inconvenience for maintenance and use.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: the main shaft speed change device that the vertical lathe of the quick and maintenance convenient of a kind of simple and compact for structure, speed governing is provided.
The utility model solves the technical scheme that its technical problem adopted: the main shaft speed change device of described vertical lathe; It is characterized in that: comprise variable-frequency motor, pulley transmission mechanism and two retaining gearboxes; The output shaft of variable-frequency motor is connected through the power shaft of pulley transmission mechanism with two retaining gearboxes, and the output shaft of two retaining gearboxes connects main shaft through gear drive.
Variable-frequency motor can adapt to the busy shift under the different working conditions through changing the output speed that frequency changes motor; Two retaining gearboxes have bottom gear, two gears of top gear; It is device conventional or that can realize; Have advantages such as compact conformation, volume mass is little, efficient is high, running is steady, shortened driving-chain greatly, simplified transmission process through two retaining gearboxes; Reduced the trouble point, maintenance convenient.
The beneficial effect that the utility model had is:
The main shaft speed change apparatus structure compact of vertical lathe adopts variable-frequency motor to change the output speed of motor through changing frequency, thereby adapts to the busy shift under the different working conditions; Shorten driving-chain greatly through two retaining gearboxes, simplified transmission process, reduced the trouble point, maintenance convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, variable-frequency motor; 2, belt pulley I; 3, belt; 4, belt pulley II; 5, the power shaft of two retaining gearboxes; 6, two retaining gearboxes; 7, the output shaft of two retaining gearboxes; 8, gear drive I; 9, power transmission shaft; 10, gear drive II; 11, main shaft.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1; The main shaft speed change device of vertical lathe; Comprise variable-frequency motor 1, pulley transmission mechanism and two retaining gearboxes 6; The output shaft of variable-frequency motor 1 is connected through the power shaft 5 of pulley transmission mechanism with two retaining gearboxes, and the output shaft 7 of two retaining gearboxes connects main shaft 11 through gear drive.
Two groups of gear drives are set in the present embodiment, and the output shaft 7 of two retaining gearboxes passes to power transmission shaft 9 with power through gear drive I8, and power transmission shaft 9 is given main shaft 11 through gear drive II10 with transmission of power again.
During work; Start variable-frequency motor 1; Through pulley transmission mechanism (comprising belt pulley I2, belt 3, belt pulley II4, as shown in Figure 1) transmission of power is kept off gearboxes 6 to two, realize speed changes through two retaining gearboxes 6; Give main shaft 11 through the output shaft 7 and the gear drive of two retaining gearboxes with transmission of power then, realize the speed change of main shaft 11.
