Description
Technical field
The utility model is related to a kind of machining tool, specially a kind of cutter of processing butterfly type valve angle slot.
Technical background
It is the framework partial schematic diagram of the newly developed double flange high-performance dish valve bodies of Fisher Co., Ltd of the U.S. as shown in Figure 1,
The butterfly type valve both ends increase left flange 102, the right flange 103 for connecting, and end face length is also increased than old-fashioned butterfly type valve
Very much.Angle slot 101 is the critical seal position of butterfly type valve, more demanding in processing to slot bottom surface and side：Rough surface
Degree be Ra1.6, surface profile 0.05mm, at present butterfly type valve have the angle of 3 kinds of models.It is original to be for machining angle slot
25*25 square peripheral groove knives are restructured, and since hole end surface is deeper in the novel butterfly type valve, cutter length is limited, such fixed cutting tool
Position it is less, it is also necessary to pad angle skewback and operate that the slightly improper angle for resulting in angle slot is suddenly big or suddenly small, and slot bottom generation connects
Tool marks, surface roughness and profile tolerance are not satisfied by drawing requirement, after being required for multiple trial cut when processing every time, carry out CMM
It detects to determine whether angle and size meet drawing requirement, causes processing efficiency extremely low.
Utility model content
The purpose of this utility model is that：It provides a kind of with easy for installation, angle is accurate, realizes standardized processing
The cutter of butterfly type valve angle slot solves the problems, such as that slot bottom connects tool marks, surface roughness and dimensional accuracy, high in machining efficiency.
To achieve the goals above, the utility model provides the following technical solutions：
A kind of cutter of processing butterfly type valve angle slot, which is characterized in that including knife bar, blade, pressing plate, screw, card slot, institute
It states card slot to be arranged on knife bar, the knife bar front end is provided with the insert groove with angle of inclination, and the blade is mounted on blade
In slot；Be provided with screw fixed hole on the knife bar, be provided with pressing plate mounting hole among the pressing plate, the screw fixed hole with
It is fixed by screw between pressing plate mounting hole；The pressing plate both ends are respectively arranged with downward snap fit tabs, fixed lobe, the card
It closes protrusion to be fastened in card slot, the fixed lobe presses on blade.
Preferably, the knife bar is cylinder, and the included angle A ° between the blade and knife bar is 18 ° or 21 °.
Preferably, the blade model NG3M320LK KC5025, the shape of the insert groove and the shape phase of blade
It coincide.
The beneficial effects of the utility model are：
Utility model device, a kind of cutter of processing butterfly type valve angle slot, including：Knife bar, blade, pressing plate and spiral shell
Nail, wherein blade are mounted on the insert groove of knife bar, are compressed by screw and pressing plate；Handle of a knife use cylindrical type, have it is easy for installation,
Angle accurate profile；By the way that the insert groove with angle of inclination will be processed as on slot knife rod head, and blade is installed, makes product
An angle correspond to one angle slot cutter, such cutter is achieved that standardization, directly can with machining, overcome with
A corresponding corresponding angle block gauge is carried out multiple trial cut to past different angle shared one and CMM frequently detects the shortcomings that processing, thorough
Bottom solves the problems, such as that slot bottom connects tool marks, surface roughness and dimensional accuracy, to improve processing efficiency.

Specific implementation mode
In conjunction with attached drawing 1,2,3,4, specific embodiment of the present utility model is explained as follows：
A kind of cutter of processing butterfly type valve angle slot, including knife bar 1, blade 2, pressing plate 3, screw 4, card slot 5, knife bar 1 be
Cylinder, the included angle A ° between blade 2 and knife bar 1 are 18 ° or 21 °；Card slot 5 is arranged on knife bar 1, and 1 front end of knife bar is provided with band
It is standard insert, model NG3M320LK KC5025, shape and the blade 2 of insert groove to have the insert groove at angle of inclination, blade 2
Shape match, blade 2 can be mounted on insert groove in.
It is provided with screw fixed hole on knife bar 1, pressing plate mounting hole 31, screw fixed hole and pressing plate are provided among pressing plate 3
It is fixed by screw 4 between mounting hole 31, and then pressing plate 3 is made to be fixed on knife bar 1；3 both ends of pressing plate are respectively arranged with downward card
Protrusion 32, fixed lobe 33 are closed, snap fit tabs 32 can be fastened in the card slot 5 of knife bar 1, and fixed lobe 33 presses on blade 2,
To make blade 2 be fixed in insert groove.
Utility model is exemplarily described in above-mentioned combination attached drawing, it is clear that the utility model implements not by upper
The limitation of mode is stated, if this insubstantial improvement of the methodology and technical solution progress of the utility model is used, or
