Abstract

The utility model belongs to the field of machining and cutting of woods, and in particular relates to a dismounting-type conical tooth tenon cutter. The dismounting-type conical tooth tenon cutter comprises a cutter bar and a plurality of conical tooth cutting blades, wherein the plurality of conical tooth cutting blades are sleeved on the cutter bar; each conical tooth cutting blade comprises a conical tooth cutting thin blade and a bore spine cutting thick blade; a cutter handle is arranged at one end of the cutter rod; a bearing is arranged between the cutter handle and the conical tooth cutting thin blades and is sleeved on the connection end of the cutter bar and the cutting handle; a threaded section is arranged at the other end of the cutter bar; an adjusting fixing nut is arranged on the threaded section. Relative to the existing integrated conical tooth tenon shank milling cutter, according to the utility model, the intensity of the cutting blades is improved, the accuracy of cutters is improved, the material cost is reduced, the machining cost is reduced, the blades can be dismounted and convenient to maintain and repair, the cutter has a simple structure, and the machined wood tenoning accuracy is high.

Description

A kind of reassembling type cone box pin joint cutter

Technical field

The utility model belongs to timber processing cutting field, relates in particular to a kind of reassembling type cone box pin joint cutter.

Background technology

Current common wood finger joint cone box pin joint shank milling cutter is generally all-in-one-piece, converted timber thickness can not regulate, and due to himself reasons in structure, often due to hoarding of wood chip, cause the problem of swaging clamp and Repeated Cutting, thereby easily there is the phenomenons such as burr in the timber that accelerates cutter passivation and process, this type of cutter in use for some time can be because wearing and tearing reduce its precision in addition, and service life is short, therefore can not meet current wood working industry requirement.

Utility model content

Defect and deficiency that the utility model exists in order to solve above-mentioned prior art, provide a kind of simple in structure, and blade is dismantled and assembled, and maintenance is convenient, and the timber tenon processing to close precision high, the dismountable cone box pin joint cutter that extend service life.

The technical solution of the utility model: a kind of reassembling type cone box pin joint cutter, comprise knife bar and be socketed in the some cone tooth cutting tips on knife bar, described cone tooth smear metal blade comprises that cone tooth cuts thin blade and bore spine cuts thick blade, described knife bar one end is provided with handle of a knife, described handle of a knife and cone tooth cut between thin blade and are provided with bearing, described bearing holder (housing, cover) is connected on knife bar and handle of a knife link, and the described knife bar other end is provided with thread segment, and described thread segment is provided with adjusting hold-down nut.

Preferably, the quantity that described cone tooth cuts thin blade is 4-5 sheet, and the quantity that described cone tooth cuts thick blade is 1, and every two cone teeth cut between thin blade and are provided with pad, and cone tooth cuts thin blade and bores tooth and cut and between thick blade, be also provided with pad.

It is that timber edge is repaired that cone tooth cuts thick blade major function.

Preferably, described cone tooth cut thin blade and cone tooth cut thick blade all have two cutting cutters tooth, the centre bore Central Symmetry of described cutting cutter tooth position phase blade, each cutting cutter tooth be provided with the cutting blade with point of a knife.

Preferably, described cutting blade is carbide alloy cutting blade, and it is welded on cutting cutter tooth.

The utility model closes shank milling cutter with respect to existing whole cone box pin joint, has improved blade strength, has improved tool precision, reduce material cost, reduced processing cost, simultaneously simple in structure, blade is dismantled and assembled, and maintenance is convenient, and the timber tenon processing to close precision high.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 bores the schematic diagram that tooth cuts thin blade in the utility model.

1. handle of a knifes in figure, 2. bearing, 3. bores tooth and cuts thin blade, and 4. pad, 5. bores tooth and cuts thick blade, 6. regulates hold-down nut, 7. cutting blade, 8. knife bar, 9. centre bore, 10. cutting cutter tooth.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail, but is not the restriction to the utility model protection domain.

As shown in Figure 1, a kind of reassembling type cone box pin joint cutter, comprise knife bar 8 and be socketed in 6 cone tooth cutting tips on knife bar 8, cone tooth smear metal blade comprises that 5 cone teeth cut

thin blade

3 and 1 bore spine cuts thick blade 5, knife bar 8 left ends are provided with handle of a knife 1, and handle of a knife 1 and cone tooth cut between thin blade 3 and be provided with bearing 2, and bearing 2 is socketed on knife bar 8 and handle of a knife 1 link, knife bar 8 right-hand members are provided with thread segment, and thread segment is provided with and regulates hold-down nut 6.Every two cone teeth cut between thin blade 3 and are provided with pad 4, and cone tooth cuts thin blade 3 and cone tooth and cuts between thick blade 5 and be also provided with pad 4.Cone tooth cuts thin blade 3 and cone tooth and cuts thick blade 5 and all have two cutting cutters tooth 10, centre bore 9 Central Symmetries of cutting cutter tooth 10 position phase blade, and each cutting cutter tooth 10 is provided with the cutting blade 7 with point of a knife.Cutting blade 7 is carbide alloy cutting blade, and it is welded on cutting cutter tooth 10.

The utility model can regulate hold-down nut to increase or reduce the quantity that cone tooth cuts thin blade by unclamping or tightening, thereby the timber of processing different-thickness reaches the multiplex function of a cutter.

Bearing 2 of the present utility model can be done guide effect, in use according to the form of master plate, processes the timber of various forms, also can effectively reduce the cutting force in cutter use simultaneously.

Cone tooth of the present utility model cuts thin blade all has an aperture with the centre that cone tooth cuts thick blade, can coordinate with knife bar by this hole, blade is carried out axial location, the end that passes through screw is again to clamping force, reach the combined effect that cutter uses, cutter compact overall structure, stable, need blade grind again or because of a slice blade damage wherein need to change or during reconditioning blade be all very simply.

During the utility model assembling, can distribute by both sides side set, much knives are used in combination tooth pitch and equate.

The utility model also can be assembled into helical form when assembling, can guarantee that cutter cuts smoothly, reduces the resistance in Tool in Cutting process, reduces tool wear, tool life.
