Abstract
The utility model relates to the technical field of machine tools, in particular to a gearshift mechanism of a gear box, which comprises a body. The top of the body is equipped with a gearshift oil cylinder and a gearshift piston is arranged inside the gearshift oil cylinder. A gearshift pull rod is arranged inside the gearshift piston and the gearshift pull rod is connected with a gearshift shaft. Gearshift dialing pieces are not adopted by the rotary table gear box gearshift mechanism of the digital control gantry milling machine and the gearshift efficiency is improved. According to the gearshift mechanism of the utility model, the gearshift oil cylinder is directly assembled with the gearshift shaft without gearshift dialing pieces, thereby improving the gearshift efficiency. Meanwhile, the dead locking of the gear box is avoided. The gearshift mechanism is good in effect.
Description
Technical field
The utility model relates to the machine tool technology field, especially a kind of gear-box gearshift.
Background technique
In lathe work, need come gear-box is shifted gears according to actual conditions, be used for reaching the speed of suitable running, convenient processing, what but existing gearshift used is the gearshift plectrum, and so just cause shifting gears oil cylinder and slip shaft centre distance are long, are easy to generate stuck phenomenon.
Summary of the invention
In order to overcome existing gearshift stuck deficiency easily: the utility model provides a kind of gear-box gearshift.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of gear-box gearshift, comprise body, described body top is provided with the gearshift oil cylinder, and described gearshift oil cylinder inside is provided with range piston, described range piston inside is provided with the gearshift pull bar, and described gearshift pull bar connects the gearshift axle.
The beneficial effects of the utility model are: this CNC planer type milling machine turntable gear-box gearshift has been cancelled the gearshift plectrum, heighten gearshift efficient, gearshift oil cylinder and gearshift axle directly are assembled together, thereby realize to shift gears plectrum, heightened gearshift efficient, gear-box can be not stuck, and using effect is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Among the figure 1, the gearshift oil cylinder, 2, range piston, 3, the gearshift pull bar, 4, the gearshift axle, 5, body.
Embodiment
As Fig. 1 is structural representation of the present utility model, and a kind of gear-box gearshift comprises body 5, described body 5 tops are provided with gearshift oil cylinder 1, described gearshift oil cylinder 1 inside is provided with range piston 2, and described range piston 2 inside are provided with gearshift pull bar 3, and described gearshift pull bar 3 connects gearshift axle 4.
To shift gears pull bar 3 and gearshift axle 4 of this gear-box gearshift directly is assembled together, and such fit has been cancelled the gearshift plectrum.When being under the driving of range piston 2 at hydraulic oil of oil cylinder or during down different position, be assemblied in gear on the gearshift axle 4 also in different positions, thereby realized gear in the different positions gear engagement different with other, realized the function of shifting gears.Because gearshift pull bar 3 is to connect with range piston 2 by bearing, gearshift pull bar 3 can rotate at range piston 2 simultaneously, makes gearshift axle 3 when rotating, and range piston 2 does not change, in order to avoid destroy the sealing between piston and the oil cylinder.
Claims (1)
