Abstract
The utility model relates to a rotary metal ceramic seal groove shaping turning tool, which belongs to a tool used in machining. A blade groove (5) is arranged on either side of one end of the tool body (1) according to the size of the blade, a bolt hole is formed at the bottom of the blade groove (5) in a distance from the center, and a screw compresses a blade (2) with a cutting edge in the blade groove (5) on the tool body (1); when one edge of the blade (2) is abraded, a new edge can be replaced only by rotating the blade (2). The rotary metal ceramic seal groove shaping turning tool has the advantages that good surface quality of work pieces can be obtained, the production efficiency is improved, and the use cost of the tool is reduced.
Description
[technical field]
The utility model relates to a kind of cutter that uses in the machining, used a kind of indexable cermet shaped profile turning cutter when especially relating to Vehicle Processing bearing ring seal groove.
[background technology]
The bearing ring seal groove is complex-shaped, size is little, required precision is high, and the parameter that relates to has angle, chamfering R, groove depth, groove width of seal groove etc.In order to process qualified bearing ring workpiece, satisfy bearing ring seal groove quality requirement, the existing method of forming processing of adopting more.
At present, the cutter of domestic processing seal groove, a kind of is welded type ordinary rigid alloy seal groove moulding cutter, another kind is the machine folder two-edged carbide alloy seal groove moulding cutter that can replace.
Existing welded type ordinary rigid alloy seal groove moulding cutter as shown in Figure 1, be after being welded to blade (2) on the cutter hub (1), by the moulding of high-speed wire linear patterning method, though manufacturing expense is low, yet have the following disadvantages: it is in close relations that cutter is installed the skills involved in the labour of adjusting with the workman, be the qualification rate that workman's technical merit has determined product, influenced productivity ratio to a certain extent; The processing method of cutter and material behavior make cutter in use occur tipping and built-up edge phenomenon easily.
The seal groove moulding cutter that can replace of existing machine folder two-edged carbide alloy as shown in Figure 2, blade (2) is provided with pressing plate (3), by screw (4) blade (2) is fixed on the cutter hub (1), and cutter life is slightly high, the tool changing adjustment technology is simple, can reduce the generation of defective work; But this cutter will be made its manufacturing cost height by the cutting tool factory of specialty; Therefore, the cutting tool factory just agree produce when this cutter had only production lot enough big, and domesticly only had one, two tame overseas-funded enterprises to possess production capacity.
Two kinds of cutters all can not satisfy the requirement that obtains better product quality and continuous lifting productivity ratio with lower cost simultaneously in sum.
[summary of the invention]
In order to overcome the deficiency in the background technology, the utility model discloses a kind of indexable cermet seal groove shaped profile turning cutter, by establishing an insert groove according to blade size at the cutter hub front end, make cutter have positive rake angle, can increase the cutting edge sharpness, reduce cutting force, reduce cutting temperature; And at the bottom of its insert groove, establish a screw, and by special-shaped screw blade being clamped on the cutter hub, the purpose that only the blade transposition can easily need have been realized when having realized changing blade has improved production efficiency, has reduced the cutter use cost.
In order to realize the foregoing invention purpose, the utility model by the following technical solutions:
A kind of indexable cermet seal groove shaped profile turning cutter, cutter hub one end either side is provided with insert groove according to blade size, depart from the center at the bottom of the insert groove and be provided with screw, screw with blade pressing in cutter hub upper slitter film trap; Each limit of described blade is a linear pattern, and each angle of blade is provided with cutting edge; Described blade center hole is a taper hole, and screw has departure at the bottom of blade center hole and the insert groove.
Described indexable cermet seal groove shaped profile turning cutter, described insert groove has inclined angle.
After adopting technique scheme, the beneficial effect that the utlity model has is:
Indexable cermet seal groove shaped profile turning cutter described in the utility model owing to select cermet material for use, makes blade not only have good toughness, and plasticity_resistant deformation and wearability are also very superior; Because insert groove is set by blade size and inclined angle is arranged, and makes cutter that positive rake angle be arranged, and has increased the cutting edge sharpness, has reduced cutting force, has reduced cutting temperature; Center line by screw at the bottom of the insert groove and blade taper hole has a departure, and blade and cutter hub are compressed.This lathe tool can make workpiece obtain good surface quality, reduces tipping and built-up edge phenomenon greatly; Specifically enhance productivity, reduce the advantage of cutter use cost.

Among the figure: 1, cutter hub; 2, blade; 3, pressing plate; 4, screw; 5, insert groove; 6, taper hole.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is further specified.
At the cutter structure in Fig. 1, Fig. 2 of the indexable cermet seal groove shaped profile turning cutter shown in Fig. 3, cutter hub 1 one end either sides are provided with insert groove 5 according to blade size, depart from the center and be provided with screw at 5 ends of insert groove, and screw is pressed in blade 2 in the cutter hub 1 upper slitter film trap 5; Described blade 2 each limit are linear pattern, and blade 2 each angle are for being provided with cutting edge; Described blade 2 centre bores are taper hole 6, and blade 2 centre bores and 5 end of insert groove screw have departure e; Described insert groove 5 has inclined angle.
Selecting no nickel cermet material for use is blade 2 materials, and this material not only has good toughness, and plasticity_resistant deformation and wearability are also very superior; Because blade 2 is close to the insert groove 5 of cutter hub 1, in order to make cutter obtain positive rake angle, reaching increases the cutting edge sharpness, reduce cutting force, reduce cutting temperature and obtain the purpose of good crudy, when cutter hub 1 front end one side is operated on film trap 5 according to blade size, should make insert groove 5 have inclined angle; Should set the width of Tool in Cutting sword according to institute's machining bearing seal groove size, select SCMW120408 square blade 2 for use, and processing cutting edge with the high-speed wire linear patterning method at its four angles, purpose is fully used the material of blade 2, has reduced the cost of cutter.
When indexable as shown in Figure 4 cermet seal groove shaped profile turning cutter uses, when screw 4 is tightened, screw 4 cone caps are given pressure in taper hole 6 left sides on the blade 2 and since on the cutter hub 1 on the center line of screw and the blade 2 taper hole 6 eccentric amount e is arranged, the stressed F that is divided into of blade
1, F
2, F
1Effect make blade 2 and cutter hub 1ab, ac face level compress F
2Effect blade 2 and insert groove bottom surface are compressed, so but this moment the cutter operate as normal.The replacing of blade 2 is in proper order: be rotated counterclockwise screw 4 blade 2 is unclamped, blade 2 half-twists are promptly changed a cutting edge, screw 4 is screwed in cutter hub 1 screw again, compress blade 2.
The utility model improves 2.2 times than welding fabrication cutter cutting speed under the feed same case, the life-span is improved 3 times, has improved production efficiency greatly when guaranteeing crudy, and cutter is produced preparatory period weak point, with low cost; Can generally promote in Production of bearing enterprise.
