Abstract

The utility model discloses a chamfering cutter for an intersecting line orifice. An installation basal plane of a blade is arranged on the upper surface of a cutter body, a blade which is an arc blade made of an elastic steel plate is installed on the installation basal plane, and the bending direction of the arc of the blade is consistent with the turning direction of the cutter. Chamfering processing can be performed on a closed angle at intersection angle position of an intersecting line through elasticity of the blade and a cutting edge of the blade. By installing the blade on the cutter body, an inner blade and an outer blade can be simultaneously installed to perform chamfering processing on an inner angle and an outer angle of the intersecting line orifice simultaneously, so that the problem of chamfering of an intersecting line intersected angle formed by intersected holes in the part processing can be effectively solved, processing of the closed angle at the positions of the intersected holes of air conditioner valve body can be achieved, and working efficiency is improved. The chamfering cutter for the intersecting line orifice is suitable for power heads on an automatic production line and a combined machine tool which have multiple stations and clamps.

Description

A kind of intersection aperture chamfering tool

Technical field

The utility model relates to a kind of gang tool that on the building-block machine unit head, uses, and is specifically related to a kind of a kind of intersection aperture chamfering tool that can carry out chamfering to the sharp-pointed angle of cut that the intersection of formation is located in crossing aperture.

Background technology

At present, the chamfering that the mechanical processing industry part intersects the intersection wedge angle that processing back, hole forms is a difficult problem: at first, its interior angle or exterior angle not in one plane, but on an arc surface; Secondly, the distance along circular arc between the interior exterior angle is different, and for the thinnest, vertical direction is just thick more in the center line horizontal direction at interior exterior angle, and the method that therefore is difficult to employing machining is carried out chamfering.In manufacturings such as air-conditioning valve bodies, the chamfering of phase perforation wedge angle has plenty of and adopts the hand grinding method, has plenty of the employing sand-blast, employing etch that also has and blast removal method, but all exist efficient low, part is had defectives such as damage, cleaning be not thorough.If wedge angle cleaning is unclean, tend to cause the sharp corner material fragmentation to drop in the work, cause that spool stops up, entire machine can't operate as normal etc. serious consequence.

The utility model content

Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of a kind of intersection aperture chamfering tool that the sharp-pointed angle of cut that intersects the intersection that forms between the hole is carried out chamfering.

Technical scheme: for realizing above-mentioned purpose; A kind of intersection aperture chamfering tool of the utility model; The upper surface of said cutter hub is provided with the installation base surface of blade, and blade is installed on installation base surface, and said blade is the cambered blade that spring steel plate is processed; The arc-shaped bend direction of said blade is consistent with the gyratory directions of cutter, relies on the elasticity of blade and cuts with the cutting edge of the blade wedge angle to intersection angle of cut place.

As preferably, cutter and outer cutter in said blade comprises, the middle part of cutter hub is provided with screw; Cutter simultaneously is fastened on installation base surface through pressing plate and screw with cooperating of screw with outer cutter in said.Specifically, on installation base surface, being equipped with cutter with outside cutter, pressing plate is placed on the blade, again screw is passed pressing plate and packs in the screw and carry out fastening.

In said cutter and outer cutter be employing have certain rigidity slim, have elasticity, blade that the steel plate that hardens is made; The curved shape of spring steel plate of cutter and outer cutter in said, and can be along with the continuous variation of place, exterior angle distance in the workpiece intersection aperture, simultaneously change in the curvature of cutter and outer cutter steel plate bending, in circumference range, obtain onesize chamfering with assurance interior angle and exterior angle.

Beneficial effect: the utility model relates to a kind of intersection aperture chamfering tool; Through blade is installed on cutter hub, cutter and outer cutter in preferably installing simultaneously carry out chamfer machining simultaneously to the interior angle and the exterior angle in intersection aperture; Effectively solve a chamfering difficult problem that intersects the intersection angle of cut that forms between the hole in the part processing; Thoroughly solve the processing of place, crossing hole wedge angles such as air-conditioning valve body, improved operating efficiency, the building-block machine and the unit head on the transfer matic that are particularly suitable for multistation, multiple clip use.

Description of drawings

Fig. 2 is the sketch map of the utility model institute processing work.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done explanation further.

As depicted in figs. 1 and 2; A kind of intersection aperture chamfering tool of the utility model comprises cutter hub 6, and the upper surface of cutter hub 6 is provided with the installation base surface 4 of blade; On installation base surface 4, blade is installed; Blade is the cambered blade that spring steel plate is processed, and the arc-shaped bend direction of blade is consistent with the gyratory directions of cutter, relies on the elasticity of blade and with the cutting edge of blade the wedge angle at intersection angle of cut place is carried out chamfer machining.

In the present embodiment, the blade of blade for adopting the steel plate that hardens to be made with certain rigidity, cutter 2 and outer cutter 5 in blade comprises, the middle part of cutter hub 6 is provided with screw 8; Interior cutter 2 is fastened on the installation base surface 4 of cutter hub 6 through screw 3 and pressing plate 1 with outer cutter 5 simultaneously.Interior cutter 2 and outer cutter 5 be employing have certain rigidity slim, have elasticity, blade that the steel plate that hardens is made.The curved shape of spring steel plate of interior cutter 2 and outer cutter 5, and can be along with the continuous variation of intersection angle of cut place, exterior angle distances in the workpiece 9, change the curvature of interior cutter 2 and outer cutter 5 steel plate bendings simultaneously, to obtain onesize chamfering.The direction of the arc-shaped bend of interior cutter 2 and outer cutter 5, consistent with the gyratory directions of cutter, promptly the chamfering at intersection angle of cut place be the dependence blade elasticity, cut with the cutting edge of blade.

The intersection aperture chamfering tool of the utility model in use; The handle of a knife 7 of this chamfering tool is packed in the front hole of intersection chamfering dynamic head main spindle; By the chamfering unit head rotation, advances to the top of arriving at the intersection angle of cut of chamfering tool is provided, radially convergence is until the angle of cut place that touches intersection, to accomplish the interior angle 11 of workpiece 9 and the processing at exterior angle 10.The intersection aperture chamfering tool of the utility model also can only be installed an interior cutter 2 (or outer cutter 5), and the interior angle 11 (or exterior angle 10) of workpiece is carried out chamfer machining separately.

The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
