Description of drawings
Fig. 1 is the overall structure front view of transition seat of the present invention, Fig. 2 is the I-I cutaway view of Fig. 1, Fig. 3 is the stereogram of transition seat of the present invention, Fig. 4 utilizes transition seat of the present invention as the schematic diagram of processing combustion machine compressor exhaust casing inner casing space inclined hole auxiliary part, in figure: the direction of being pointed to B by A is defined as X-direction, the direction of being pointed to C by B is defined as Y direction, and the direction of being pointed to E by B is defined as Z-direction.
The specific embodiment
the specific embodiment one: in conjunction with Fig. 1～Fig. 3 explanation, the transition seat that the processing combustion machine compressor exhaust casing inner casing space inclined hole of present embodiment is used, described transition seat is provided with the inner chamber 1 of perforation vertically, be used for connecting the actuating unit that is connected with large right-angle milling head, the profile of described transition seat is comprised of Rotary-table 2 and cylinder 3, one is made in the major diameter end face of Rotary-table 2 and a side end face of cylinder 3, the opposite side end face of cylinder 3 is provided with annular projection 4, be used for being connected the location with the recessed seam of large right-angle milling head, Rotary-table 2 and the coaxial setting of cylinder 3, the external diameter of the major diameter end face of Rotary-table 2 is less than the external diameter of cylinder 3, be laid with eight circular grooves 5 on the excircle sidewall of cylinder 3, be used for alleviating transition seat weight, be convenient to install and adjust, part on cylinder 3 between adjacent two circular grooves 5 is engaging lug 6, be processed with a connecting hole 7 on each engaging lug 6, being used for screw corresponding to large right-angle milling head is connected, be processed with two radial direction through hole 8 on the lateral wall of Rotary-table 2, two radial direction through hole 8 are used for observing actuating unit and little right-angle milling head connection when transition seat is connected with little right-angle milling head, two radial direction through hole 8 are symmetrical arranged with respect to the axis of Rotary-table 2, be processed with vertically six screwed holes 9 on the minor diameter end face of Rotary-table 2, six uniform being arranged on same circumference of screwed hole 9, six screwed holes 9 are for the connection of transition seat with the corresponding screw of little right-angle milling head, α in an acute angle between the center line of wherein two the residing center lines of screwed hole 9 in six screwed holes 9 and adjacent connecting hole 7, described sharp angle α=2.734 °.
The specific embodiment two: in conjunction with Fig. 2 explanation, the total height h1=132mm of the transition seat of present embodiment, the height h2=20mm of cylinder 3.Other is identical with the specific embodiment one.
Transition seat using method: before processing, first large right-angle milling head is connected with main shaft, after actuating unit is connected to large right-angle milling head, after being located by seam with large right-angle milling head, transition seat is connected with screw, little right-angle milling head is connected with the minor diameter end face of the Rotary-table of transition seat, and after angle is finely tuned, tighten screw, can process.Its Main Function is the orientation that changes the medium and small right-angle milling head of processing, the protection actuating unit.
because this cutter in processing is in a locus, it is in X-axis, Y-axis, the projection relation of Z axis is fixing according to oneself warp of drawing processing request, be set in and have a cube in the space, alphabetical A is used respectively on cubical eight summits, B, C, D, E, F, G, H represents (see figure 4), its length of side meets three axial projection's relations, the physical location of cutter is on this cubical space diagonal AF, become the β angle between the frame line AB of this diagonal AF and cube lower plane, β=113.616 ° (drawing is given), and become the γ angle between the space diagonal plane at this diagonal AF place and one of them vertical plane of this cube, γ=60 °.according to the corresponding relation of each length of side in cube, setting this cubical height is 1, the length that can calculate the diagonal AG of rear end face is 2, be located at take this cube right flank length of side GF as a right-angle side, rear end face diagonal AG is another right-angle side, space diagonal AF is in the right angled triangle of hypotenuse, little internal acute angle delta is 23.616 °, can get as calculated, diagonal AF length in this space is 2.1828, take the high FC of this cube front end face as a right-angle side, bottom surface diagonal AC is another right-angle side, space diagonal AF is in the right angled triangle of hypotenuse, the space diagonal AF length and cubical high corresponding relation of utilizing oneself to obtain, can this to the angle theta between space diagonal AF and cubical height, θ=62.734 °.Because of with transition seat that right-angle milling head is connected on the screwed hole of six corresponding connections is arranged, six screwed holes are uniform on same pitch circle, between each hole, the angular interval value is 60 °, therefore after transition seat upper screwed hole journal offset angle α, α=2.734 ° (i.e. α in an acute angle between the center line of wherein two the residing center lines of screwed hole 9 in six screwed holes 9 and adjacent connecting hole 7), little right-angle milling head and the angle theta that can realize after corresponding screwed hole connects between institute's mounting cutter and cubical height.As without this transition seat, can't complete the processing that diagram requires.The passage when inclined hole that processes is the air-flow displacement directly has influence on the flow of air-flow as excessive or mistake young pathbreaker, and then affects the operating efficiency of unit, thereby can't meet design requirement.
