Abstract
The invention discloses a worktable gearbox for a vertical lathe. A gear transmission mechanism of a gearbox comprises a belt pulley, an output gear and a sliding gear pulled by a shifting fork, two coaxial oil cylinders are arranged in the gearbox and use the same piston rod, and the shifting fork is mounted on the piston rod between the two oil cylinders. By the aid of the technical scheme, the number of meshing gears is decreased, the structure of a box body is simplified, manufacture and assembly are simpler, noise of the box body is lowered, stepless speed regulation for rotation of a worktable of the vertical lathe is realized, machining efficiency is improved, high cutting torque can be obtained at an intermediate speed by means of three-gear speed variation, and the efficiency of a motor is made full use of. Compared with a product of the prior art, the worktable gearbox can function in energy conservation as the performance of a 55Kw three-gear frequency conversion box body is equivalent to that of a 75Kw high-low-gear frequency conversion box body.
Description
Technical field
The invention belongs to the technical field of Metal Cutting Machine Tool, relate to the transmission system of lathe, more particularly, the present invention relates to a kind of workbench gearbox of vertical lathe.
Background technology
The rotating speed of standard type double column vertical lathes of the prior art is step speed change, and the casing inside engaged gear is many, and the noise of casing is bigger, and processing needs speed change, and the platform that must stop work could be shifted, delayed production efficiency.
Summary of the invention
Problem to be solved by this invention provides a kind of workbench gearbox of vertical lathe, its objective is the infinitely variable speeds that realizes workbench.
To achieve these goals, the technical scheme taked of the present invention is:
The workbench gearbox of vertical lathe provided by the present invention; The gear drive of described gearbox comprises belt pulley, output gear and shifting slide gear; Described shifting slide gear is stirred through shift fork; Establish two coaxial oil cylinders in the described gearbox, these two oil cylinders adopt same piston rod, and described shift fork is installed on two piston rods between the oil cylinder.
The drive motors of described gearbox is the ac variable frequency speed regulation motor.
Described shifting slide gear is that three gears connect as a whole triple gear.
The present invention adopts technique scheme, has not only reduced the number of meshing gear, has simplified the structure of casing, makes the manufacturing assembling more simple, has reduced the noise of casing; Realize vertical lathe workbench rotation stepless speed regulation, improved the efficient and the product precision of processing; Use three retaining speed changes, can make when intermediate speed, can obtain the bigger cutting moment of torque; Fully play the power of motor; Compare with the product with prior art, the 55Kw frequency conversion cabinet characteristic of third gear frequency conversion is equal to the high and low shift frequency conversion casing of 75Kw, so also play energy-conservation effect.
Description of drawings
The mark of facing down among expressed content of each width of cloth accompanying drawing of this specification and the figure briefly explains:
Fig. 1 is the expansion sketch map of gearbox designs of the present invention;
Fig. 2 is the structural representation in jack shaft of the present invention cross section.
Be labeled as among the figure:
1, belt pulley, 2, piston rod, 3, piston, 4, oil cylinder, 5, oil cylinder, 6, shift fork, 7, shifting slide gear, 9, output gear.
The specific embodiment
Contrast accompanying drawing below, through the description to embodiment, specific embodiments of the invention is done further detailed explanation, to help those skilled in the art inventive concept of the present invention, technical scheme is had more complete, accurate and deep understanding.
Like Fig. 1, the expressed structure of the present invention of Fig. 2, be a kind of workbench gearbox of vertical lathe, the gear drive of described gearbox comprises belt pulley 1, output gear 9 and shifting slide gear 7, described shifting slide gear 7 is stirred through shift fork 6.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize the infinite variable speed goal of the invention of workbench, the technical scheme that the present invention takes is:
As shown in Figure 1; The workbench gearbox of vertical lathe provided by the present invention; Establish two coaxial oil cylinders 4, oil cylinder 5 in the described gearbox, these two oil cylinders 4, oil cylinder 5 adopt same piston rod 2, and described shift fork 6 is installed on the piston rod 2 between two oil cylinders 4, the oil cylinder 5.
Adopt technique scheme, not only reduced the number of meshing gear, simplified the structure of casing, make the manufacturing assembling more simple, reduced the noise of casing.
The drive motors of described gearbox is the ac variable frequency speed regulation motor.Utilize the ac variable frequency speed regulation motor in the certain speed scope, to realize stepless speed regulation, and speed governing is convenient, has improved the efficient and the product precision of processing.
Described shifting slide gear 7 is that three gears connect as a whole triple gear.Realize that through triple gear third gear expands speed change, strengthen speed adjustable range, and when intermediate speed, can obtain the bigger cutting moment of torque, fully play the power of motor.
Operation principle of the present invention:
Referring to Fig. 1:
When oil cylinder 5 entering pressure oils, piston rod 2 drives shift forks 6 together with piston 3 and moves on to the third gear position, and the shifting slide gear 7 that also drives on the II axle simultaneously moves to third gear position and corresponding gears engaged;
When oil cylinder 4 gets into pressure oils, oil cylinder 5 not oil-feeds, then piston rod 2 drives shift forks 6 together with piston 3 and moves on to the I gear and put, and also drives shifting slide gear 7 on the II axle simultaneously and moves to the I gear and put and corresponding gears engaged;
When oil cylinder 4 and oil cylinder 5 get into pressure oil simultaneously; At this moment the diameter of piston rod 2 two ends diameters and piston 3 is different; Consequent pressure differential; Make piston rod 2 and piston 3 drive shift forks 6 and be in the II gear and put, also drive shifting slide gear 7 on the II axle simultaneously and move to the II gear and put and corresponding gears engaged;
More than be three gears, in three gears, the frequency of adjustment variable-frequency motor just can obtain different rotating speed output.
Use the effect of three class gear shift frequency conversion casing:
1, not only reduces the number of meshing gear, simplified the structure of casing, made the manufacturing assembling more simple, reduced the noise of casing.
2, realize vertical lathe workbench rotation stepless speed regulation, improved the efficient of processing.
3, in addition according to the characteristic of variable-frequency motor, the relation of moment of torsion, rotating speed, frequency is used three retaining speed changes; Can make when intermediate speed; Can obtain the bigger cutting moment of torque, fully play the power of motor, compare with product of the same type; The 55kw frequency conversion cabinet characteristic of our third gear frequency conversion is equal to the high and low shift frequency conversion casing of 75kw, so also play energy-conservation effect.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
