Abstract
The utility model discloses a cutter bar sealing and mounting structure comprising a cutter bar frame, a cutter bar sleeve and a cutter bar, wherein a first frame gland and a second frame gland are respectively fixed at the left end and the right end of the cutter bar frame and both externally sleeved on the cutter bar; the cutter bar sleeve is positioned between the first frame gland and the second frame gland; a first washer and a second washer are respectively arranged at the left end and the right end of the cutter bar sleeve and externally sleeved on the cutter bar; a first oil seal is mounted between the first frame gland and the cutter bar; the right end of the first oil seal clings to the first washer; a second oil seal is mounted between the second frame gland and the cutter bar; and the left end of the second oil seal clings to the second washer. By adopting the cutter bar sealing and mounting structure, the sealing performance of cutter bar cutting fluid can be effectively improved, and the service life of the cutter bar is prolonged at the same time.
Description
Technical field
The utility model relates to the machine tool technology field, especially relates to a kind of knife bar sealing mounting structure.
Background technology
Knife bar is an important component part of machine tool; Existing machine tool knife bar mounting structure is to be enclosed within on the said knife bar outside the knife bar cover; Said knife bar support is enclosed within said knife bar outward and puts, and is fixed with the first support gland and the second support gland respectively at said knife bar support two ends, and the deficiency of this kind structure is: the firstth, and knife bar adopts the THK ball spline to pay (comprising splined shaft and supporting base); Procurement price is high, and the price of Φ 25-Φ 40 specifications is from 2500-3500 unit/cover; The secondth, this knife bar outer surface is provided with 3 pairs of keyways, is used to prevent the knife bar rotation, because a side has the backflow cutting fluid of certain pressure, must adopt sealing to flow to the right side to stop cutting fluid; But because of 3 pairs of keyways of knife bar exist, the sealing difficulty is so often cause cutting fluid to be leaked; The 3rd is the supporting employing and the supporting copper sheathing of knife bar of knife bar, in case wearing and tearing need integral replacing, it is higher to change difficulty of processing and cost.
The utility model content
The utility model technical problem to be solved is to provide a kind of supporting stable, the preceding knife bar sealing mounting structure of good sealing effect.
The technical scheme of the utility model is following: a kind of knife bar sealing mounting structure; Comprise knife bar support, knife bar cover and knife bar; Outer being enclosed within on the said knife bar of wherein said knife bar cover, said knife bar support is enclosed within said knife bar outward and puts, and is fixed with the first support gland and the second support gland respectively in said knife bar support right ends; This first support gland and the second support gland are all outer to be enclosed within on the said knife bar; And said knife bar overlaps between the said first support gland and the second support gland, and its main points are: the right ends at said knife bar cover is respectively equipped with first packing ring and second packing ring, and this first packing ring and second packing ring are enclosed within outward on the said knife bar; Between said first support gland and knife bar, first oil sealing is installed; The right-hand member of this first oil sealing is close on said first packing ring, between said second support gland and knife bar, second oil sealing is installed, and the left end of this second oil sealing is close on said second packing ring.Adopt above structure, first oil sealing and second oil sealing are installed, can effectively raise knife bar cutting fluid sealing property, change first oil sealing simultaneously and second oil sealing is convenient and swift;
Between the right ends portion of said knife bar cover and said knife bar, be separately installed with first axle sleeve and second axle sleeve, the right-hand member of the left end of this first axle sleeve and second axle sleeve is against respectively on the side of said first packing ring and second packing ring.Adopt above structure; Install first axle sleeve and second axle sleeve of DU alloy additional; Both improved the service life of knife bar, and change convenient, through in time more changing knife rod, knife bar cover; The axiality of the knife bar centre of location and machine tool chief axis is had a greater degree of improvement and keep, and then effectively guaranteed the crudy of workpiece.
Beneficial effect: the employing of the utility model can effectively improve the sealing property of knife bar cutting fluid, the service life of having improved knife bar simultaneously; The utlity model has simple in structure, be convenient for changing, characteristics such as cost is low, good stability.
