Abstract
The utility model discloses a cutting bed feeding device for a timber rotary cutter, which comprises a driving system and is characterized in that a cutting feed lead screw rack of the driving system is arranged in a cavity of a movable guide rail; a lubricating oil is stored in the cavity; and a cutting lead screw and a lead screw nut arranged on the cutting feed lead screw are positioned in a lubricating oil body of the cavity. The cutting bed feed device of the timber rotary cutter has reasonable structural design, can keep the long-term lubricating performance of the lead screw nut, i.e. between a screw pair and the cutting feed lead screw, and can reduce the wear between the screw pair and the cutting feed lead screw to minimum extent, thereby greatly prolonging the service life of the screw pair and the cutting feed lead screw, ensuring the cutting feed precision during the rotary cutting operation and improving the quality of slices.
Description
Technical field
The utility model belongs to the timber rotating-cutting equipment, is specifically related to the cutter bed feed arrangement that a kind of cutting knife rotary-cut that is used for timber lathe drives.
Background technology
Timber lathe is the equipment that long journey timber is rotated serial section, it can be adjusted according to the thickness of section, roll by a plurality of pressure roller clamping timber, feed velocity by adjusting the feed bed from fast to slow and follow the Changing Pattern of the size of timber diameter then, the thickness of the timber tangent plane under the rotary-cut is remained unchanged from start to end, satisfy the requirement of section.
The cutting knife feed arrangement of existing timber lathe generally adopts the leading screw feeding, and the process of leading screw feeding is controlled easily, adjusts the precision height, but influenced by the load of moment of torsion and pressure during the leading screw feeding, and the suffered pressure of its flank of tooth is bigger.Existing cutter bed feed arrangement generally adopts at the load position and carries out drip lubrication, and the screw thread pair quick abrasion, the life-span that cooperate with leading screw are low, can't satisfy the instructions for use of cutting knife feeding.Be the long-term operating accuracy that guarantees leading screw, should carry out wearability control, guarantee the good lubrication performance between leading screw and the screw thread pair, reduce the rate of wear.
The utility model content
The utility model provides a kind of reasonable in design, can keep feed screw nut is the cutter bed feed arrangement of timber lathe of the long-term greasy property of screw thread pair and feed leading screw, it can drop to bottom line with the wearing and tearing of the two, prolong the service life of feed screw nut and feed leading screw greatly, and the feed precision when guaranteeing the rotary-cut operation, improve the section quality.
The technical scheme that the utility model adopted is as follows:
A kind of cutter bed feed arrangement of timber lathe, comprise a transmission system, the feed leading screw that it is characterized in that described transmission system is erected in the cavity of a knife rest moving guide rail, in the described cavity lubricating oil is set, the feed screw nut of this feed leading screw and setting thereof is arranged in the lubricated oil body of this cavity.
Concretely, the both ends of described knife rest moving guide rail are provided with bearing respectively, and described feed leading screw is located in the described cavity by this bearing bracket stand.
Described feed screw nut is the copper nut of thread set on the feed leading screw.
The top of described knife rest moving guide rail has the cell body of opening, and described feed leading screw axially is erected in the lubricated oil body in this cavity along this cavity.
Further comprise the feed arrangement transmission mechanism of driving in described feed leading screw, this feed transmission mechanism comprises a gear reduction unit and a drive motors, and this drive motors directly drives this gear reduction box.
Described gear reduction unit comprises a power output shaft, and described drive motors directly drives with gearratio=15.83 of this output shaft with drive motors and is connected.
The cutter bed feed arrangement of this timber lathe has effectively improved the transmission lubrication effect of the two by feed leading screw and the feed screw nut that is mated are carried out the oil immersed type design, and the two friction loss is reduced to minimum.The structural design of this kind mode is simple, by cavity at feed leading screw peripheral hardware knife-carrier moving guide rail, and by bearing with the feed lead screw shaft in being erected at this cavity, form the oil immersed type assembly structure, feed leading screw in the cavity is immersed in the lubricated oil body all the time, and the bearing between its two ends and the cavity is a sealed bearing.So, lubricating oil is filled in the cavity, and the opening by knife rest moving guide rail top can observe directly feed leading screw and the situation of feed screw nut in lubricating oil.
The drive unit of this feed leading screw more can adopt the gear reduction unit that is connected with transmission output shaft to finish, this gear reduction unit directly is connected with drive motors, can realize the best transmission effect of gearratio=15.83 of drive motors and this output shaft accurately, it cooperates turbine, worm geared mechanism to compare with the belt transmission of transmission, has more stable drive, characteristics that precision is high.
The beneficial effects of the utility model are, the cutter bed feed arrangement reasonable in design of this timber lathe, can keep feed screw nut is the long-term greasy property of screw thread pair and feed leading screw, it can drop to bottom line with the wearing and tearing of the two, prolong the service life of feed screw nut and feed leading screw greatly, and the feed precision when guaranteeing the rotary-cut operation, improve the section quality.
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
