Description
Technical field
The utility model relates to the machine tool technology field, relates in particular to a kind of machine tool guideway carriage.
Background technology
At present, straight-line parts adopt the rolling coefficient little usually on the Digit Control Machine Tool, and translational speed is fast, and linear rolling track realizes, but on the machine tool of this large-scale, heavy load of digital control plane milling and boring machine, and not bery applicable.A lot of producers generally adopt many line slideways more than two to finish the purpose of bearing large load in order to solve the large difficult problem of load; But be difficult to like this guarantee on each bar line slideway, slide block is installed contact-making surface can both be in absolute plane value at grade, necessarily has because the unevenness that the processing accumulated error causes, will be so that each slide block discontinuity affects its service life and machine tool accuracy.
The utility model content
Technical problem to be solved in the utility model is: provide that a kind of bearing capacity is high, the absorbing performance is good, the machine tool guideway carriage of long service life.
For solving the problems of the technologies described above, the technical solution of the utility model is: the machine tool guideway carriage, comprise be used to the slide that connects moving-member on the described lathe, described slide have one uncovered on described lathe the hydraulic fluid chamber of fixed guide, be provided with one in the described hydraulic fluid chamber and be used for the slide block that offsets with described fixed guide, described slide block is fixedly installed on the described slide, a side that offsets with fixed guide on the described slide block is provided with the hydraulic pressure oil groove, described slide is provided with oil inlet passage and the oil discharge passage that is communicated with by described hydraulic pressure oil groove, described oil discharge passage is provided with the throttling pressure regulator valve, is provided be used to the potted component that seals described hydraulic fluid chamber between described slide block and the slide.
As a kind of improvement, described hydraulic pressure oil groove has several, and described several hydraulic pressure oil grooves are along the radially extension of described slide block and pool together.
After having adopted technique scheme, the beneficial effects of the utility model are: because a side that offsets with fixed guide on the slide block is provided with the hydraulic pressure oil groove, under the sealing function of potted component, form a cavity between hydraulic pressure oil groove and the fixed guide, when oil inlet passage oil-feed under an elevated pressures, when oil discharge passage is fuel-displaced under relatively low pressure, cavity between hydraulic pressure oil groove and the fixed guide just forms a band pumping cavity, produce the power that slide block and slide are upwards floated, reduced to a great extent the coefficient of friction between slide block and the fixed guide, and vibration absorption ability is significantly improved; Besides, lowered machining accuracy and assembly precision, slightly had not at ordinary times between the multi-slide in the presence of all, slide block can rely on the difference in height between the numerous slide blocks of power auto-compensation that hydraulic oil produces, evenly improve bearing capacity so that each slide block is stressed, greatly prolonged the service life of slide block.
Owing to being provided with several hydraulic pressure oil grooves on each slide block, so that the hydraulic oil power that slide block is subject to is more even, further having improved vibration absorption ability and bearing capacity.
