Detailed description of the invention
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
The mentality of designing of the invention is: any two circular holes chosen on small flange plate are benchmark circular hole, the large flange card using the ring flange quadrant that provides of the invention to plan thereunder is drawn alignment boost line, the reference axis consistency from top to bottom of quadrant that need determine on small flange plate face with selected two circular holes of the alignment boost line of drawing.
As shown in Figure 1, this ring flange quadrant is plan, and is symmetrical structure, comprises two cone seats, 1, two one-level rule, 2, two secondary rule 3 and penholder 4:
The upper end thereof of two one-levels rule 2, its lower end connects cone seat 1 by one-level pin 5, and one-level pin 5 is hinged with cone seat 1, and one-level pin 5 and one-level are advised 2 coaxial and be connected by bearing;
Secondary rule 3 are " L " shape and are arranged at the top of one-level rule 2 symmetrically, the underarm 31 of secondary rule 3 is connected to the middle part of one-level rule 2 by interpolar part 6, interpolar part 6 advises 2 perpendicular to one-level and the two is connected by bearing, and the end that interpolar part 6 and secondary advise 3 underarms 31 is hinged;
The two ends of penholder 4 connect by shoulder 7 end that secondary advises 3 upper arm 32, and the end of upper end and the penholder 4 of shoulder 7 is hinged, take on 7 and secondary advise 3 coaxial and its lower end and secondary advise 3 upper arm 32 ends and be connected by bearing.
Hinged or bearing connection between each parts, one-level rule 2 are realized and secondary rule 3 can relative to the determined vertical planes upset of two benchmark circular holes by the combination of multiple free degree, and penholder 4 is by the combination maintenance level of the free degree, thus can ensure that paintbrush is rule at the surface uniform of large flange dish.
When using this ring flange quadrant to plan, can directly cone seat 1 be inserted in two benchmark circular holes, as long as ensure that cone seat 1 just can move in the transfer of benchmark circular hole, but the normal correspondence of two bump joint pipes of different size is provided with the benchmark circular hole of different-diameter, in order to adapt to two bump joint pipes of different size, the invention provides embodiment as shown in Figure 2:
The below of cone seat 1 is provided with conehead 8 separably, the bottom of conehead 8 is set to the cone bar 81 matched with benchmark circular hole, its top is set to basal diameter and is greater than the diameter of benchmark circular hole and the round end 82 raised up, and the bottom surface of cone seat 1 is provided with the spacing blind hole 83 matched with round end 82.The benchmark circular hole of different-diameter is optional selects the conehead 8 using and match with it, and in the cone bar 81 rotating insertion benchmark circular hole of conehead 8, the spacing blind hole 83 of cone seat 1 is placed in the top of round end 82 and bores seat 1 and can be able to relatively rotate with round end 82.
Advise in 3 switching processes at penholder 4 and secondary, in order to meet the requirement of multiple degrees of freedom combination, two shoulders 7 can rotate around the jointed shaft of itself and penholder 4, identical in order to ensure the angle that two shoulders 7 rotate relative to penholder 4 further, the upper end of two shoulders 7 is set to circle, and its end face is provided with engaging tooth, the upper end of two shoulders 7 is meshed by engaging tooth.
As mentioned above, one-level pin 5 is hinged with cone seat 1, interpolar part 6 and secondary advise 3 hinged, take on 7 and penholder 4 hinged, as long as ensure that hinged both can rotate around jointed shaft and can not be scattered, the invention provides articulated structure as shown in Figure 3, comprise bearing pin 9 and check ring 10, the both ends of bearing pin 9 are provided with the annular slot 91 for check ring 10 buckle.Both hinged hinged ends are needed to be sheathed on bearing pin 9 periphery, two check rings 10 are stuck in the annular slot 91 at bearing pin 9 both ends, thus both hinged ends are clipped between two check rings 10, realize hinged and ensure that two hinged ends can not be deviate from from bearing pin 9.
In order to improve the line precision that this ring flange quadrant is plan further, need ensure that the central axis of two hinged parts is in the same plane, this be the invention provides to a kind of embodiment: the hinged end of two parts be hinged is set to mutually clamp shape, namely the hinged end of one of them parts is set to the pin-joint piece 11 that extends along its central axis, and the hinged end of another parts is set to the hinged intermediate plate of two panels 12 about its central axis symmetry and the space be provided with between the hinged intermediate plate 12 of two panels for clamping pin-joint piece 11.
Particularly, as also shown in e.g. figs. 4-7, the upper end of two one-level rule 2 is set to pin-joint piece 22 and hinged intermediate plate 12 respectively; The end of the underarm 31 of secondary rule 3 is set to hinged intermediate plate 12, and the end of the interpolar part 6 hinged with it is then set to pin-joint piece 11; The bottom of one-level pin 5 is set to hinged intermediate plate 12, and the upper end of corresponding cone seat 1 is then set to pin-joint piece 11.
The operation principle of the invention is: during use, first the conehead 8 of boring seat 1 or different size is put into two benchmark circular holes on small flange plate, and paintbrush is held in penholder 4, with on the other hand by being pressed on one-level pin 5, ensure that the center of rotation of cone seat 1 is vertical, another hand-held penholder 4, upset one-level rule 2, secondary rule 3 and penholder 4, the nib of paintbrush is made to touch the upper surface of large flange dish, and draw vestige at the upper surface ecto-entad of large flange dish, this vestige is the perpendicular bisector of two basic circle hole circle center line connectings, then by one-level rule 2, secondary rule 3 and penholder 4 turn to the opposite side of large flange dish round about, vestige is drawn at the opposite side of large flange dish by above-mentioned steps, this vestige is also the perpendicular bisector of two basic circle hole circle center line connectings, it is clear to be described by drawn by paintbrush two vestige, these two vestiges are alignment boost line, with two benchmark circular holes determine that a wherein reference axis of quadrant aligns, so far scratching process completes.
The position line at two drawn alignment boost lines alignment fuel outlet places can complete the precise positioning of the rigging position of circular hole on the position line at fuel outlet place and small flange plate.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
