Abstract
The utility model relates to the technical field of machine tool equipment, in particular to a hydraulic damping device for a machine tool. The hydraulic damping device comprises an oil tank and a damping oil cylinder, and the hydraulic damping device is characterized by further comprising a hydraulic pump connected with the oil tank. A precise oil filter is arranged between the hydraulic pump and the oil tank, a proportional overflow valve is connected with an output pipeline of the hydraulic pump, an output of the proportional overflow valve is connected with an electromagnetic directional valve through a pipeline, and an oil return circuit of the damping oil cylinder is connected with the oil tank through the electromagnetic directional valve. The hydraulic damping device adopts the proportional overflow valve to replace a common electromagnetic valve to supply oil for a return circuit of the damping oil cylinder, and adjustment of damping values of workpieces in different weights can be conveniently achieved by controlling the proportional overflow valve. The hydraulic damping device for the machine tool is simple in structure and convenient to use.
Description
Technical field
The utility model relates to the machine tool technical field, is specifically related to a kind of hydraulic damping device that is used for lathe.
Background technology
Go up when workpiece carried out helix or the processing of other curve interpolatings or workpiece carried out the calibration location at turning center (or rotary table) at present, owing to there is the influence of mechanical clearance, in rotation process or during mechanical commutation vibration can appear often, cause processing to interrupt, even can damage cutter, and workpiece surface quality is impacted.And some mechanical clearance can not be eliminated fully such as the drive gap of gear pair.Main shaft (or workbench) upright usually, horizontal turning center adopts the control of circle grating full cut-off ring, produces vibration in order to prevent to eliminate alliance ring error in starting and stopping or rotary course, and requiring increases damping to main shaft or workbench, reduces inertia.The damping that in the prior art workpiece of Different Weight is required is also different, and damping is too little, do not have corresponding effect, and damping is too big, except increasing friction, reduces outside the response speed, also can increase unnecessary power waste.
Summary of the invention
The purpose of this utility model is to avoid the single defective of prior art lathe damping function that a kind of hydraulic damping device that is used for lathe is provided, it adopts proportional pressure control valve to replace common magnetic valve and gives damping oil cylinder loop fuel feeding, thereby effectively solves the defective that exists in the prior art.
For achieving the above object, the technical scheme that the present invention takes is: described a kind of hydraulic damping device that is used for lathe, comprise oil sump and damping oil cylinder, be characterized in also comprising the hydraulic pump that links to each other with oil sump, be provided with precise oil filter between hydraulic pump and the oil sump, proportional pressure control valve links to each other with the output pipe of hydraulic pump, and the output of proportional pressure control valve connects solenoid directional control valve by pipeline, and the oil return line of damping oil cylinder links to each other with oil sump by solenoid directional control valve.
Described proportional pressure control valve is provided with Pressure gauge and pressure switch with the pipeline that links to each other of solenoid directional control valve.
The invention has the beneficial effects as follows: described a kind of hydraulic damping device that is used for lathe, it adopts proportional pressure control valve to replace common magnetic valve and gives damping oil cylinder loop fuel feeding, by the control of Comparative Examples overflow valve, can realize adjustment easily to Different Weight workpiece damping value; It is simple in structure, easy to use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural principle schematic diagram.
Among the figure: 1. oil sump, 2. precise oil filter, 3. hydraulic pump, 4. proportional pressure control valve, 5. Pressure gauge, 6. solenoid directional control valve, 7. damping oil cylinder, 8. pressure switch.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present invention and feature are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
As shown in Figure 1, described a kind of hydraulic damping device that is used for lathe, comprise oil sump 1 and damping oil cylinder 7, be characterized in also comprising the hydraulic pump 3 that links to each other with oil sump 1, be provided with precise oil filter 2 between hydraulic pump 3 and the oil sump 1, proportional pressure control valve 4 links to each other with the output pipe of hydraulic pump 3, and the output of proportional pressure control valve 4 connects solenoid directional control valve 6 by pipeline, and the oil return line of damping oil cylinder 7 links to each other with oil sump 1 by solenoid directional control valve 6.
Described proportional pressure control valve 4 is provided with Pressure gauge 5 and pressure switch 8 with the pipeline that links to each other of solenoid directional control valve 6.
Described a kind of hydraulic damping device that is used for lathe; it in use; according to the actual weight of workpiece, give the aanalogvoltage of proportional pressure control valve 4 corresponding sizes, proportional pressure control valve 4 is just exported the oil pressure of certain flow (pressure); pressure oil arrives damping oil cylinder 7 by solenoid directional control valve 6; the compression spring, the pressure of last spring affacts on main shaft or the chuck, forms certain damping; reduce the inertia of main shaft or chuck, make main shaft or chuck held stationary in starting and stopping or rotary course.When not needing damping, proportional pressure control valve 4 and solenoid directional control valve 6 are not worked, and damping oil cylinder 7 pushes back the pressure oil in the cylinder in the oil sump by solenoid directional control valve 6 by spring.
The above only is preferred embodiment of the present invention, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
