Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] Such as figure 1 As shown, a hydraulic shifting device for a numerically controlled machine tool includes a gear box 1, and lubricating oil is arranged in the box 1. The improvement lies in: the first gear shaft 2 and the second gear shaft 3 arranged in parallel in the upper and lower directions are arranged in the gear box body 1; The three gears 4 and the fourth gear 5, the double sliding gears include the first gear 6 meshing with the third gear 4 and the second gear 7 meshing with the fourth gear 5, and the hydraulic pressure is also integrated in the gear box 1. The oil cylinder 8, the piston 81 of the hydraulic oil cylinder 8 drives the double sliding gear to slide axially along the first gear shaft 2 through the connecting piece 9, so as to realize the meshing between the first gear 6 and the third gear 4 or the second gear 7 and the first gear Two states of...

Abstract

The invention relates to a hydraulic gear shifting device used for a numerically-controlled machine tool. The hydraulic gear shifting device used for the numerically-controlled machine tool comprises a gearbox casing; a first gear shaft and a second gear shaft which are arranged in parallel in the up-and-down direction are arranged inside the gearbox casing; the first gear shaft is provided with double linked sliding gears; the second gear shaft is provided with a third gear and a fourth gear; the double linked sliding gears comprise the first gear engaged with the third gear and the second gear engaged with the fourth gear; a hydraulic oil cylinder is further integrated in the gearbox casing; a piston of the hydraulic oil cylinder drives the double linked sliding gears through a connection part to slide in the axial direction of the first gear shaft so as to achieve the two states that the first gear is engaged with the third gear or the second gear is engaged with the fourth gear. By means of the technical scheme, the hydraulic oil cylinder is adopted as a power component, automatic gear shifting can be achieved under the condition of no stop, and meanwhile, as the gears which do not work are separated after gear shifting, the problem of gear noise is solved.

Description

technical field [0001] The invention relates to the field of numerical control machine tools, in particular to a hydraulic shifting device for numerical control machine tools. Background technique [0002] As the market continues to change, the requirements for the automation of CNC machining are getting higher and higher. High-efficiency, high-precision, and low-cost CNC machine tools have become the new favorites in the market. At present, the CNC lathe with mechanical frequency conversion structure mainly realizes the stepless speed change mode on the gear position through the switching of the gear position, which can increase the cutting torque of the machine tool. Generally, this kind of gear shift can be solved in two ways: one is to change the gear gear in the gear by manually switching the gear meshing mode by pulling the handle; the other is to switch gears by means of electromagnetic clutch bit. Both of the above two methods have their own shortcomings: the first...
