Further, the number of springs is greater than one, is evenly distributed on the open end of rectangular channel.
The beneficial effects of the present invention are:
1. help nozzle body to move along the linear path for being roughly parallel to holder axis by location hole and rectangular channel, it will
Nozzle body is positioned and is guided to mounting hole, then tightens bolt, can fixed nozzle body；It is easy to operate, in nozzle body traveling process
And collision dynamics few with fixture collision frequency is small, while not damaging nozzle body can effective fixed nozzle body, and bolt is twisted
Clamp force is adjustable, guarantees fixed stability.
2. metal hardness at location hole is lower than the hardness of rectangular channel, flexible hinge structure is formed, so that rectangular channel can be with
It is rotated around location hole axle center, so that the openings of sizes of fine adjustment rectangular channel and mounting hole, is easily installed and fixed nozzle body.
3. the rectangular channel between location hole and mounting hole forms horn-like structure, suitable convenient for guidance nozzle body displacement
Benefit enters in mounting hole, and in processing, can prevent nozzle body from exiting out of mounting hole because of stress.
4. spring is arranged in the open end of rectangular channel, spring is in compressive state when fixture works, after the completion of bore hole,
Bolt is unclamped, spring bounces immediately, and the open end of rectangular channel is opened, convenient for the taking-up of nozzle body.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing.
Fig. 1 is the structural schematic diagram of nozzle body boring jig of the invention.
In figure, 1, chuck body；11, rectangular channel, 12, location hole, 13, mounting hole, 14, horn-like structure, 15, spring；
2, bolt；3, nozzle body.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, is clearly and completely retouched to the technical solution in embodiment
It states.Obviously, described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Bright embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of nozzle body boring jig, including chuck body 1 and bolt 2, the chuck body 1 are bulk
Structure, side set open rectangular channel 11, and 11 root of rectangular channel is equipped with location hole 12, and mounting hole 13 is equipped in the middle part of rectangular channel 11, fixed
Position hole 12 is connected to mounting hole 13 by rectangular channel 11, and the diameter of location hole 12 is greater than the diameter of mounting hole 13, rectangular channel 11
Open end is equipped with through-hole, and the through-hole and location hole 12 are spatially vertical, and screw thread is set in through-hole.Nozzle body 3 is placed in positioning
In hole 12, so that nozzle body 3 can be entered in mounting hole 13 by rectangular channel 11, while it is cantilever that the part of nozzle body 3, which is stretched out,
Structure, hole to be processed are located on the cantilever stretched out；After nozzle body 3 is placed in mounting hole 13, then bolt 2 is screwed into through-hole
In, the opening of rectangular channel 11 is compressed, nozzle body 3 can be fixed and be positioned.Location hole 12 guidance and help nozzle body 3 into
Enter rectangular channel 11, the guidance of rectangular channel 11 and help nozzle body 3 move along the linear path for being roughly parallel to holder axis, enter
Into mounting hole 13, in moving process, nozzle body 3 is few with fixture inner wall collision frequency and collision dynamics is small, not will cause damage
Wound.
In the present embodiment, the metal hardness at the location hole 12 is lower than the hardness of rectangular channel 11, forms flexible hinge link
Structure is easily installed nozzle body 3 so as to the openings of sizes of fine adjustment rectangular channel 11 and mounting hole 13.
In the present embodiment, the nozzle body boring jig is made of brass.Brass has good mechanical, physics and technique
Performance, moderate strength are suitable for forging.Nozzle body boring jig made of brass has stronger wear-resisting property and fatigue resistance,
And hardness is far below nozzle body 3, it is not easy to damage nozzle body 3.
In the present embodiment, 11 diameter of rectangular channel is become narrow gradually from location hole 12 to 13 direction of mounting hole, forms loudspeaker
Shape structure 14 moves to mounting hole 13 from location hole 12 convenient for nozzle body 3；The big opening end diameter of horn-like structure 14 is slightly larger than nozzle
3 outer diameter of body, to guide nozzle body 3 to be made smooth advances mounting hole 13, horn-like 14 osculum end of structure fastens rectangular channel in bolt 2
After 11, it is open and becomes smaller because of the closure of rectangular channel 11, when can prevent processing, nozzle body 3 is exited out of mounting hole 13.
In the present embodiment, the inside of mounting hole 13 is equipped with resilient cushion.The drilling axial force generated when drilling is perpendicular to nozzle
Body 3, impact when being dissipated by the deformation of elastoplasticity (or viscoelasticity) hysteresis of resilient cushion or absorbing bore hole, reduces nozzle body 3
Shaking in process, increases its stability, guarantees Boring preciseness, and secondly resilient cushion has elasticity, be located at nozzle body 3 with
Between fixture, there is certain decrement, it is ensured that nozzle body 3 is fitted closely with fixture, increases firm effect, to prevent
Nozzle body 3 is relative to 13 skew of mounting hole.
In the present embodiment, the open end of rectangular channel 11 is equipped with spring 15, and the spring 15 is parallel with through-hole.When bore hole is completed
Afterwards, bolt 2 is unclamped, spring 15 bounces immediately, the open end of rectangular channel 11 is strutted, convenient for taking out nozzle body 3.
In the present embodiment, the spring 15 is greater than one, is evenly distributed on the open end of rectangular channel 11, guarantees 15 bullet of spring
Hui Shi, dynamics is uniform, in case nozzle body 3 collides fixture inner wall.
