Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material detection, in particular to a nut material detection fixture. Background Art
[0002] Currently, there is no suitable fixture to clamp nuts when using a direct reading spectrometer to test their material quality. To this end, the present application designs a nut material testing fixture that is used to clamp nuts when testing their material quality and is used in conjunction with a direct reading spectrometer. Summary of the Invention
[0003] In order to make up for the deficiencies in the prior art, the utility model provides a nut material detection fixture.
[0004] A nut material detection fixture includes a fixture body, characterized in that:
[0005] The clamp body is a cylinder with an internal opening, and a hexagonal nut is placed in the internal opening. Four slideways are evenly opened on the circumference of the rear end of the clamp body, and the clamp slider a and the clamp slider b are slidably connected in the relative slideways. A thread is opened at the front end of the clamp body and a threaded sleeve is threadedly connected. When the threaded sleeve is twisted, the inner wall of the threaded sleeve contacts the clamp slider a and the clamp slider b. The positions of the clamp slider a and the clamp slider b that contact the threaded sleeve are set to inclined edges with the front lower and the back higher. When the threaded sleeve is twisted backward, the inner wall of the threaded sleeve squeezes the clamp slider a and the clamp slider b, so that the clamp slider a and the clamp slider b clamp the hexagonal nut.
[0006] Furthermore, in order to better implement the present invention, the rear end of the clamp body is fixedly connected to the clamp rear cover by a rear countersunk screw, so that the clamp slider a and the clamp slider b are limited in the slideway.
[0007] Furthermore, in order to better implement the present invention, the front end of the clamp body is fixedly connected to the clamp front cover via a front countersunk screw.
[0008] Furthermore, in order to better realize the present invention, the front cover of the clamp is provided with an opening that is the same as the internal hole of the clamp body, and a detachable sunshade is provided at the opening.
[0009] Furthermore, in order to better implement the present invention, spring wires are installed between the clamp slider a and the clamp slider b and the clamp body.
[0010] The beneficial effects of the utility model are:
[0011] The utility model provides a solution for nut material detection. In view of the characteristics of the nut having a narrow detection surface and being unable to be clamped, a clamp that can adapt to the special shape of the nut for clamping is designed through reasonable structural design, ensuring that there is no light or air leakage when the nut is tested for material quality with a direct-reading spectrometer, and providing accurate test results to customers.

[0017] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.
[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.
[0019] Figure 1-Figure 3 This is a specific embodiment of the present invention, a nut material testing fixture. Through a rational structural design, the fixture adapts to the unique shape of the nut for clamping. This ensures the closed space within the nut is maintained during material testing using a direct-reading spectrometer, helping customers obtain accurate test results. This embodiment can be used in conjunction with a direct-reading spectrometer to test difficult-to-detect nuts, particularly those with a narrow inspection surface that cannot cover the inspection aperture of a direct-reading spectrometer.
[0020] The fixture body 4 is connected to the threaded sleeve 6 with threads, the fixture slider a3 and the fixture slider b5 are installed in the slideway of the fixture body 4, the fixture back cover 2 is fixed to the fixture body 4 with a rear countersunk screw 1, the fixture front cover 7 and the fixture body 4 are fixed to the fixture body 4 with a front countersunk screw 9, and a spring wire is installed between the fixture slider and the fixture body 4. When the threaded sleeve 6 is twisted toward the fixture back cover 2, the fixture slider a3 and the fixture slider b5 are pressed inward to clamp the nut to be tested. The light shielding plate 8 is covered on the assembled nut detection fixture to ensure that the surface of the nut to be tested faces the direct-reading spectrometer, and no light or air leakage occurs during the detection process.
[0021] The method of using this embodiment is: put the hexagonal nut 10 to be inspected into the inspected hole, adjust the position, tighten the threaded sleeve 6 to drive the clamping slider to clamp the inspected nut, cover the top of the fixture with a light shielding plate 8, and place the inspected nut facing the detection needle of the direct reading spectrometer to ensure that there is no light leakage or air leakage during the detection process.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
