Abstract
The utility model relates to a fixture for the local annealing of a support plate self-locking nut. The fixture comprises a container for containing water, wherein a support frame is arranged in the container; a support panel for placing an annealing part of the support plate self-locking nut upwards is arranged on the top of the support frame; a cooling cavity in which a part below the annealing part of the support plate self-locking nut enters and which is filled by water when used is formed on the support panel; a water supply channel which is communicated with the cooling cavity and water-containing space of the container is formed on the support panel; and a limit structure which is in limit fit with the part below the annealing part of the support plate self-locking nut in the horizontal direction is arranged on the support panel. When the fixture is used, the water is filled into the fixture, so that a part of the support plate self-locking nut except for a flaring part is immersed in the water; and the flaring part is heated by flame, other parts of the support plate self-locking nut are immersed in the water, and the temperature does not exceed 100 DEG C, so the strength is not reduced, and the problem of deficiency of matching fixtures during the local annealing of the self-locking nut is solved.
Description
Technical field
The utility model relates to the supporting plate self-lock nut spot anneling and uses frock.
Background technology
In the prior art, supporting plate self-lock nut comprises expansion mouth, supporting plate and the threaded hole section that is wholely set, in the supporting plate self-lock nut triturating; Relate to the local enlarging of supporting plate self-lock nut, be about to external diameter and expand, and can not crack to 1.1 times of green diameter; But nut length is very short, needs the annealed position that 3-4mm is only arranged, and is the hollow thin-wall structure; When carrying out spot anneling, must strictly control annealed length and temperature again, accurately control heated perimeter; Not need to guarantee the annealed position temperature can not be too high; Technology difficulty is big, therefore can in the annealed process, not need annealed partly to cool off supporting plate self-lock nut, but lacks the frock that the supporting plate self-lock nut spot anneling is used in the prior art.
Summary of the invention
The purpose of the utility model is to provide and can uses frock with water-cooled supporting plate self-lock nut spot anneling to unannealed position, lacks the problem of supporting frock when solving supporting plate self-lock nut spot anneling in the prior art.
In order to address the above problem; The supporting plate self-lock nut spot anneling of the utility model is used frock; This frock comprises the container that is used to be filled with water; Be provided with bracing frame in this container, the support frame as described above top is provided with the support panel that the annealing portion that is used to supply supporting plate self-lock nut is placed up, offers on the said support panel to be used to supply get into and the water filled in use cooling chamber of part below the supporting plate self-lock nut annealing portion; Said support panel is provided with the water channel of the water space that is communicated with cooling chamber and container, and said support panel is provided with the part position limiting structure that cooperates of upper limit in the horizontal direction below the annealing portion that is used for supporting plate self-lock nut.
Support frame as described above comprises two supporting legs; Be equipped with back up pad on each said supporting leg; Be provided with the slit that is used to supply said supporting plate self-lock nut thread segment insertion between said two back up pads, the top in said slit is said cooling chamber, and the bottom in said slit is described water channel; Described position limiting structure is the limited step of being located on said two support panels, the described support panel of the common formation of said two back up pads.
The tool structure of the utility model is simple, supporting plate self-lock nut is installed is very easy to, and when the supporting plate self-lock nut annealing portion is annealed, in frock, adds water; Make the part of supporting plate self-lock nut except that expansion mouth all immerse in the water; To the expansion mouth flame heating, other positions of supporting plate self-lock nut are because under water then, and temperature can be above 100 ℃; Therefore intensity can not descend, and lacks the problem of supporting frock when having solved the self-locking out spot anneling.
Description of drawings
Fig. 1 is a supporting plate self-lock nut diagrammatic cross-section vertically among the utility model embodiment;
Fig. 2 is the left view of supporting plate self-lock nut among the utility model embodiment;
Fig. 3 is the user mode figure of frock among the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done detailed description:
The supporting plate self-lock nut spot anneling is used frock embodiment; Shown in Fig. 1 ~ 3; Supporting plate self-lock nut 8 by annealing processing comprises expansion mouth 1, supporting plate 2 and the internal thread hole section 3 that is wholely set, and this frock comprises the container 6 that is used to be filled with water, and support frame as described above comprises two supporting legs 4,4 '; Be equipped with back up pad 5,5 ' on each supporting leg 4,4 '; Two back up pads 5, be provided with the slit 9 that the thread segment 3 that is used to supply said supporting plate self-lock nut 8 inserts between 5 ', the top in said slit 9 is said cooling chamber, and the bottom in said slit 9 is the water channel of the water space of said connection cooling chamber and container; Each back up pad equal 5,5 ' is provided with the position limiting structure of the supporting plate 2 that is used to support said plate nut 8; This structure is a limited step 10,10 ', this limited step step 10,10 ' also be used for the supporting plate 2 of supporting plate self-lock nut 8 in the horizontal direction upper limit cooperate, two back up pads 5,5 ' constitute described support panel jointly.
During use, in frock, add entry, then; With 2 of the supporting plates of supporting plate self-lock nut 8 back up pad 5,5 ' step 10,10 ' go up and expansion mouth 1 up, the water surface in the adjustment container 6, make supporting plate self-lock nut 8 supporting plate 2 and internal thread segment 3 all immerses in the water and expansion mouth 1 is in more than the water surface; Heat with 7 pairs of expansion mouths 1 of flame then; After arriving preset temperature, stop heating and use water cooling, realize spot anneling.
The tool structure of the utility model is simple; The installation supporting plate self-lock nut is very easy to, and during annealing because other positions of supporting plate self-lock nut are because under water, and temperature can be above 100 ℃; Therefore intensity can not descend, and lacks the problem of supporting frock when having solved the supporting plate self-lock nut spot anneling.
Different with the foregoing description in other embodiments is; Described bracing frame can design one or more supporting leg as required; Different with the foregoing description in other embodiments is; Support panel can also be made up of a back up pad; Perforate on this back up pad, fluting or crack the back up pad upper and lower surfaces is communicated with and is communicated with water container, can make the threaded hole section of supporting plate self-lock nut insert the hole on the back up pad or stitch in and the plate supporting frame of supporting plate self-lock nut be located at said support plate upper surface and get final product; Different with the foregoing description in other embodiments is can also be provided with on the described support panel in the horizontal direction to the spacing in the horizontal direction stopper slot of the part below the annealing portion of supporting plate self-lock nut, limited block, stop screw or the like.
