Abstract
The utility model discloses a hydraulic supporting type central frame of a machine tool, which comprises an upper bracket (3) and a lower bracket (1) which are in movable connection with each other; a lathe guide rail (11) is connected with the bottom of the lower bracket (1); a hydraulic bracket is arranged at the central top of the lower bracket (1); and supporting rods (4) which are used for fixing a workpiece to be machined are arranged on the upper bracket (3) and the lower bracket (1). According to the central frame, the hydraulic brackets are adopted for supporting the workpiece, no rigid direct contact exists between each hydraulic bracket and the workpiece, no abrasion exists on the surface of the workpiece, and the vibration of the workpiece can be inhibited and absorbed, the supporting accuracy is higher, the high-speed stable gapless rotation of the workpiece can be ensured, and the grinding speed and the grinding accuracy during machining can be improved, so that the hydraulic supporting type central frame can be suitable for being used for accuracy machining. The hydraulic supporting type central frame is compact in structure, reasonable in layout, convenient to use, economic and practical and suitable for being used for the accuracy machining on long shaft parts with relatively heavy weight.
Description
Technical field
The utility model relates to a kind of machine tool component, especially a kind of machine tool hydraulic formula supporting center frame.
Background technology
At present, during the machine tooling longaxones parts, the flexural deformation that produces under gravity or cutting force effect in order to reduce part to be processed adopts supporting center frame that part is carried out supplemental support usually.Existing supporting center frame is rigid support to the support of part, the support bar of supporting center frame directly contacts with part, can produce some problems when part is long, heavier: during workpiece rotating, centre frame can produce vibration when especially Work piece high-speed rotated, and affected machining accuracy; When workpiece is heavier, can produce larger friction to support bar, and destroy the surface quality of part.
The utility model content
The purpose of this utility model is: a kind of machine tool hydraulic formula supporting center frame is provided, and it is applicable to process the fluid pressure type centre frame of heavier longaxones parts, and can not destroy the surface quality of part, to overcome the deficiencies in the prior art.
The utility model is achieved in that machine tool hydraulic formula supporting center frame, the upper bracket and the lower carriage that comprise flexible connection, bottom at lower carriage connects lathe guide rail, top, center at lower carriage is provided with hydraulic support, is provided with for the fixing support bar of workpiece to be processed at upper bracket and lower carriage.
Described hydraulic support is comprised of bearing pin, roller, bow, piston rod and hydraulic cylinder; The bottom of piston rod is connected with hydraulic cylinder, and the top of piston rod is connected with the middle part of bow by bearing pin, and the two ends of bow connect roller by bearing pin.Workpiece rotating drives roller and rolls, and makes between workpiece and the hydraulic support and forms rolling friction, can reduce friction on the impact of workpiece surface quality.
Owing to having adopted above-mentioned technical scheme, compared with prior art, the utility model adopts hydraulic support to come supporting workpiece, do not exist the direct of rigidity to contact between hydraulic support and the workpiece, to not wearing and tearing of surface of the work, can suppress and absorb the vibration of workpiece, support accuracy is higher, guaranteed the steady gapless rotation of Work piece high-speed, greatly improved the grinding speed and the precision that add man-hour, be adapted at using in the Precision Machining.The utility model is simple in structure, easily implements, and high efficiency can reduce cost of labor, and result of use is good.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of hydraulic support of the present utility model.
The specific embodiment
Embodiment of the present utility model: the structure of machine tool hydraulic formula supporting center frame as shown in Figure 1, the upper bracket 3 and the lower carriage 1 that comprise flexible connection, bottom at lower carriage 1 is connected with lathe guide rail 11 by bolt 10, be provided with for the fixing support bar 4 of workpiece to be processed at upper bracket 3 and lower carriage 1, top, center at lower carriage 1 is provided with hydraulic support, and hydraulic support is comprised of bearing pin 2, roller 6, bow 7, piston rod 8 and hydraulic cylinder 9; The bottom of piston rod 8 is connected with hydraulic cylinder 9, and the top of piston rod 8 is connected with the middle part of bow 7 by bearing pin 2, and the two ends of bow 7 connect roller 6 by bearing pin 2.
Adding man-hour, hydraulic cylinder 9 control piston bars 8 carry out the feeding of vertical direction, make roller 6 contact workpiece 5 and support the workpiece 5 of rotation, the rotation that rotarily drives roller 6 of workpiece 5 has reduced the distortion that friction and workpiece to hydraulic support 12 produce because of gravity, cutting force.The utility model compact conformation, rationally distributed, easy to operate, economical and practical, the Precision Machining of the longaxones parts that especially suitable weight is larger.
