Abstract
The invention belongs to the field of machining tools, and particularly discloses a split type milling knife for machining different chamfer grooves. The split type milling knife comprises a knife handle, a forming knife disc and a fastener, wherein the end part of the knife handle is provided with an installing base, and the end surface of the installing base is fixedly provided with a coaxial connecting pillar; the diameter of the connecting pillar is less than that of the knife handle, the diameter of the installing base is greater than that of the knife handle, and the end surface of the installing base is also provided with at least one positioning pin; the shaft core part of the forming cutter disc has a through hole, the connecting pillar is inserted into the through hole, and the end surface of the forming knife disc further has at least one positioning hole matched with the positioning pin, the positioning pin is inserted into the positioning hole, the fastener is sleeved into the connecting pillar so that the forming knife disc is fastened on the side surface of the installing base, the end surface of the knife disc is provided with a trapezoid forming chamfer edge, and the two sides of the trapezoid forming chamfer edge are provided with end surface smooth edges. The split type milling knife provided by the invention has the advantages that the processes of forming a groove, chamfering the groove and leveling two sides of the groove are finished at one time, thus the work efficiency is improved.
Description
Technical field
The invention belongs to the machining field of tool, particularly a kind of Split type milling cutter be used to processing various chamfering grooves.
Background technology
Chamfer machining is applicable to mould, mould bases chamfer machining, bed piece processing, and iron and steel processing, the sheet metal chamfering, machinery equipment chamferings etc. are widely used in the industries such as iron and steel, steel construction, mould, metal processing, hardware manufacturing; Milling cutter has a variety of, general milling cutter is the integral type milling cutter, cutterhead and handle of a knife are integrated and process, need very thick material to process, production cost is higher, and when in the cutterhead use procedure, being damaged, can't change, can only be that handle of a knife replaces together, and use cost is very large like this, its manufacturing cost makes many enterprises hang back on the large basis more, common milling cutter processing type groove also needs later on to carry out chamfer machining with the chamfering utensil, and two procedures is numerous and diverse tediously long like this, wastes time and energy, simultaneously also to need other operation to carry out smooth because the end face of chamfering pit both sides has burr, also increased the use cost of enterprise.
Summary of the invention
The objective of the invention is the weak point that exists in the above-mentioned technology, propose a kind of can the time processing groove and can chamfering, the smooth smooth chamfering forming cutter of end face.
The invention provides following technical scheme:
The smooth chamfering forming cutter of end face, it comprises handle of a knife, moulding cutterhead and securing member, the handle of a knife end is provided with a mount pad, be fixed with coaxial joint pin on the mount pad end face, the diameter of joint pin is less than the diameter of handle of a knife, the diameter of mount pad is greater than the diameter of handle of a knife, also be provided with at least one alignment pin on the mount pad end face, moulding cutterhead axle center part is provided with a through hole, joint pin inserts in this through hole, also be provided with the locating hole that at least one cooperates with alignment pin on the end face of moulding cutterhead, alignment pin inserts in the locating hole, securing member is inserted in the joint pin moulding cutterhead is fastened on the mount pad side, and the cutterhead end face is provided with trapezoidal moulding chamfering blades, and trapezoidal moulding chamfering blades both sides are provided with the smooth sword of end face.
Also be provided with safety bolt on the described securing member, this safety bolt enters with joint pin from the securing member side and offsets, and safety bolt is connected with fastener threads.
Described joint pin end face is provided with location centering parts.
Advantage of the present invention is with making alignment pin and cooperating of locating hole moulding cutterhead location more accurate, simultaneously location centering parts can accurately catch workpiece to guarantee the yield rate of product, trapezoidal moulding chamfering blades and the smooth sword of end face once finish machined grooves, to the smooth operation of groove chamfering and groove both sides, increase work efficiency.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the smooth chamfering forming cutter of end face, it comprises handle of a knife 1, moulding cutterhead 2 and securing member 3, handle of a knife 1 end is provided with a mount pad 4, be fixed with coaxial joint pin 5 on mount pad 4 end faces, the diameter of joint pin 5 is less than the diameter of handle of a knife 1, the diameter of mount pad 4 is greater than the diameter of handle of a knife 1, also be provided with at least one alignment pin 6 on mount pad 4 end faces, moulding cutterhead 2 axle center parts are provided with a through hole, joint pin 4 inserts in this through hole, also be provided with the locating hole 7 that at least one cooperates with alignment pin 6 on the end face of moulding cutterhead 2, alignment pin inserts in the locating hole, and securing member 3 is inserted in the joint pin moulding cutterhead is fastened on the mount pad side, the cutterhead end face is provided with trapezoidal moulding chamfering blades 8, and trapezoidal moulding chamfering blades both sides are provided with the smooth sword 9 of end face.
Wherein, also be provided with safety bolt 10 on the securing member 3, this safety bolt 10 enters with joint pin 4 from securing member 3 sides and offsets, and safety bolt 10 is threaded with securing member 3.
Wherein, joint pin 4 end faces are provided with location centering parts 11.
