Description

Technical Field

[0001] The present application relates to the technical field of strength detection, and more specifically, to a strength detection mechanism for stainless steel fasteners. Background Art

[0002] Stainless steel fasteners are a specific professional noun concept that includes a wide range of products. Due to their beautiful appearance, durability, strong corrosion resistance and other characteristics, stainless steel fasteners are usually used for fastening on more valuable machine parts. With the progress of society, higher requirements have been put forward for stainless steel standard parts. At present, after the production of stainless steel fasteners is completed, it is necessary to carry out sampling strength detection work on them.

[0003] After retrieval, the publication number: CN220356845U discloses a strength detection device for stainless steel fasteners, including a support bottom plate, an upper pressing block, a pressure sensor and a workbench. The left and right sides of the upper end of the support bottom plate are fixedly provided with mounting frames. A pressure sensor is installed at the central position of the lower end inside the mounting frame, and an upper pressing block is installed at the lower end of the pressure sensor, etc. This application can solve the problem that in the prior art, due to the lack of fixed positioning of stainless steel metal fasteners, they are prone to displacement when pressed, resulting in a certain deviation in the detected compressive strength.

[0004] However, although the two clamping blocks and the electric telescopic rod can be used in this application to achieve the clamping effect on both sides of the fastener to be measured, during the overall strength detection process, it is easy to have an unstable clamping state of the fastener, resulting in the phenomenon that the fastener bounces outwards under pressure or the waste residue on it splashes outwards, thus generating potential safety hazards during the detection process.

[0005] In order to solve the above problems, the present application provides a strength detection mechanism for stainless steel fasteners. Utility Model Content

[0006] The strength detection mechanism for stainless steel fasteners provided by the present application adopts the following technical solutions:

[0036] The lifting structure includes a chute 10 opened at the side end of the fixed frame 7. A threaded rod 11 is vertically rotatably installed on the inner wall of the chute 10. The bottom of the threaded rod 11 is connected to a motor 12. The motor 12 is fixedly installed at the bottom of the fixed frame 7. A threaded slider 13 is screwed on the outer wall of the threaded rod 11. The threaded slider 13 is slidably sleeved on the inner wall of the chute 10.

[0037] Both the fixed frame 7 and the transparent frame 9 are in a "mouth"-shaped hollow frame structure. And the top of the fixed frame 7 is flush with the top of the workbench 5. And the transparent frame 9 is made of transparent plastic material. The limitation of the material of the transparent frame 9 facilitates the safety protection of the fasteners and at the same time enables the observation of the detection process.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 , the clamping assembly includes an L-shaped plate 14 fixedly installed on one side wall of the top end of the workbench 5. An electric telescopic rod 15 is fixedly installed on the inner side wall of the L-shaped plate 14 through a mounting member.

The connection and control function of the controller 22 can be realized by programming, which is prior art and will not be elaborated here. And the controller 22 can also play a role in feedback and display of the detection data of the pressure sensor 4.

[0041] The implementation principle of this embodiment is as follows: When in use, while placing the stainless steel fastener to be detected on the top of the workbench 5, control the two electric telescopic rods 15 to horizontally drive the two clamping blocks 16 respectively, so as to realize the clamping work of the fastener on the workbench 5;

[0042] After that, while controlling the two motors 12 to synchronously drive the two threaded rods 11 to rotate, indirectly make the two threaded sliders 13 move vertically upward on the inner walls of the two sliding grooves 10 respectively, and then drive the transparent frame 9 to lift upward on the outer wall of the fixed frame 7, so as to realize the observable enclosure effect on the clamped fastener. Then control the detection cylinder 6 to push the whole workbench 5, so that the fastener to be detected approaches and contacts the bottom of the upper pressing block 3, and with the cooperation of the pressure sensor 4, the strength detection work of the fastener can be realized. The detection data is directly fed back to the controller 22. Among them, in the enclosure state of the transparent frame 9, it can not only not affect the observation of the fastener strength detection process, but also prevent the phenomenon that the fastener bounces outwards or the waste residue on it splashes outwards due to the problem of insufficient clamping of the fastener, thereby preventing accidental injury to the staff. When the fastener detection is completed, the workbench 5 descends passively, and at the same time, the transparent frame 9 moves vertically downward and resets on the outer wall of the fixed frame 7;

[0043] Driven by the motor 19 on the adjusting screw rod 18, the horizontal position of the supporting plate 20 on the inner wall of the moving groove 17 can be indirectly adjusted, and at the same time, the horizontal position of the workbench 5 can be indirectly adjusted, so as to facilitate the detection of fasteners at different positions.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
