[0002] Optical fiber communication refers to a way of transmitting information using light and optical fibers, which belongs to a type of wired communication. After light is modulated, it can carry information. Since the 1980s, optical fiber communication systems have had a revolutionary impact on the telecommunications industry and also played a very important role in the digital age. Optical fiber communication has advantages such as large transmission capacity and good confidentiality. The tee pipe body is one of the important components of optical fiber communication, which is convenient for signal transmission. During production, hardness detection is required to determine whether it is a qualified product.

At the same time, there is no good protection function. Once the part splashes after being pressed to a certain value, it will cause certain damage to the surrounding environment and pose a greater safety hazard. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 4 , the present invention provides a hardness detection device for the production of three-way pipe bodies, including a detection table 1 and a positioning mechanism connected to the detection table 1. The positioning mechanism includes two pressing plates 8, two push-pull plates 21, a fixed column 10, a connecting block one 14, a connecting block two 15, a spring two 20, and a spring three 22. The pressing plate 8 is movably connected to the detection table 1. The two ends of the push-pull plate 21 are connected to the connecting block one 14 and the corresponding pressing plate 8. The fixed column 10 is used to guide the connecting block one 14 and the connecting block two 15. The two ends of the spring two 20 are connected to the connecting block one 14 and the detection table 1. The two ends of the spring three 22 are connected to the connecting block one 14 and the connecting block two 15. The detection table 1 is connected with a detection mechanism, the detection mechanism is connected with a lifting mechanism for driving the detection mechanism to lift, and the lifting mechanism is used to drive the connecting block two 15 to move downward.

[0022] During processing, the workpiece is placed on the detection table 1 and located between the two pressing plates 8. Then, the cylinder 3 drives the connecting rod 4, the cross plate 5, the protective cover 6, and the detection head 16 to move downward. The pressing rod 7 exerts a downward pressure on the moving plate 12, synchronously driving the connecting block two 15 to move downward. Then, in cooperation with the use of the spring three 22, the connecting block one 14 is driven to move downward, and the spring two 20 is gradually stretched. The push-pull plate 21 exerts a pulling force on the corresponding pressing plate 8, driving the two pressing plates 8 to approach each other. When the cross plate 5 moves down to an appropriate position, the pressing plate 8 presses tightly on the workpiece, which can improve the stability of the workpiece and facilitate subsequent detection. At the same time, the protective cover 6 covers the workpiece to protect the detection area, thereby improving the safety of hardness detection.

[0023] The positioning mechanism further includes two sliding blocks 13 and two rectangular holes 9. The rectangular holes 9 are provided on the inspection table 1. The sliding blocks 13 are slidably connected to the corresponding rectangular holes 9, and the sliding blocks 13 are connected to the bottom of the pressing plate 8. The rectangular holes 9 play a good guiding role for the sliding blocks 13 and improve the stability of the movement of the pressing plate 8. During the positioning process of the workpiece, the second connecting block 15 exerts a downward pulling force on the third spring 22, driving the first connecting block 14 to move downward. The first connecting block 14 synchronously exerts a pulling force on the two push-pull plates 21, which can pull the corresponding sliding blocks 13 to move on the rectangular holes 9, synchronously driving the two pressing plates 8 to approach each other until the pressing plates 8 are pressed against both sides of the workpiece, improving the stability of the workpiece. At this time, the second spring 20 and the third spring 22 are both in a stretched state.

[0024] Both ends of the push-pull plate 21 are axially connected to the sliding block 13 and the first connecting block 14.

[0025] The fixed column 10 is fixed to the bottom of the inspection table 1. The first connecting block 14 and the second connecting block 15 are slidably connected to the fixed column 10, improving the stability of the lifting of the first connecting block 14 and the second connecting block 15.

[0026] The detection mechanism includes a connecting rod 4, a protective cover 6, a plurality of guiding protrusions 17, a detection head 16, a first spring 18, and a connecting head 19. The lifting mechanism is used to drive the connecting rod 4 to lift and lower. The guiding protrusions 17 are connected to the outside of the connecting rod 4, and the guiding protrusions 17 and the connecting rod 4 penetrate through the top of the protective cover 6. The connecting head 19 is connected to the end of the connecting rod 4. The detection head 16 is connected to the connecting head 19. The first spring 18 is sleeved on the connecting rod 4, and both ends of the first spring 18 are connected to the protective cover 6 and the connecting head 19. When the workpiece is in the positioning state, the protective cover 6 presses on the top of the inspection table 1, covering the detection area. The detection head 16 moves downward relative to the protective cover 6 but does not contact the workpiece. The first spring 18 is in a stretched state. Then, the air cylinder 3 continues to drive the connecting rod 4 and the detection head 16 to move downward, and the first spring 18 is further stretched, so that the detection head 16 presses on the workpiece for hardness detection. At the same time, the second connecting block 15 also moves further downward, and the third spring 22 is further stretched, increasing the downward pulling force exerted on the first connecting block 14, so that the pressing plate 8 is further pressed against the workpiece, ensuring the stability of the workpiece. The protective cover 6 is made of a transparent material, which is convenient for observation during detection.

[0027] There are three guiding protrusions 17 in total, and the adjacent included angles are 120°. The guiding protrusions 17 are slidably connected to the protective cover 6. The guiding protrusions 17 make the lifting of the protective cover 6 stable and prevent the protective cover 6 from rotating.

[0028] The lifting mechanism includes a bracket 2, a cylinder 3, a cross plate 5, and two pressing rods 7. The bracket 2 is connected to the top of the inspection table 1. The cylinder 3 is connected to the bracket 2, and the power output end of the cylinder 3 is connected to the connecting rod 4. The cross plate 5 is connected to the output end of the cylinder 3. The pressing rods 7 are connected to both ends of the cross plate 5, and the pressing rods 7 are slidably connected to the inspection table 1. The bracket 2 provides good support for the cylinder 3. The cylinder 3 can drive the synchronous lifting of the cross plate 5 and the connecting rod 4. The cross plate 5 drives the two pressing rods 7 to lift. When the pressing rods 7 press on the corresponding moving plates 12, the downward movement of the connecting block two 15 can be driven.

[0029] Both sides of the connecting block two 15 are connected with moving plates 12, and the end of the pressing rod 7 matches the corresponding moving plate 12.

[0030] The bottom of the inspection table 1 is connected with a support side plate 11. A vertical groove is arranged inside the support side plate 11. The end of the moving plate 12 is slidably connected with the corresponding vertical groove, improving the stability of the lifting of the support side plate 11.

[0031] Working principle: Place the workpiece on the inspection table 1. The cylinder 3 drives the connecting rod 4, the cross plate 5, the protective cover 6, and the inspection head 16 to move downward. The cross plate 5 drives the two pressing rods 7 to move downward synchronously. The pressing rods 7 press on the moving plates 12, driving the moving plates 12 to move downward, realizing the downward movement of the connecting block two 15. With the use of the spring three 22, the connecting block one 14 is driven to move downward, and the spring two 20 is stretched. The connecting block one 14 exerts a pulling force on the two push-pull plates 21, and the two pressing plates 8 can be pulled to approach each other. When the cross plate 5 descends to an appropriate position, the pressing plates 8 are pressed tightly against both sides of the workpiece, realizing the locking of the workpiece, improving the stability and facilitating subsequent processing. At this time, the protective cover 6 presses on the inspection table 1 and covers the inspection area to protect the inspection area, thereby improving the safety of hardness detection. The spring one 18 is in a stretched state, and the inspection head 16 has not yet contacted the workpiece. The cylinder 3 continues to drive the downward movement of the cross plate 5, the connecting rod 4, and the inspection head 16, so that the inspection head 16 presses on the workpiece for hardness detection processing. The further downward movement of the cross plate 5 can drive the downward movement of the connecting block two 15, and the spring three 22 is further stretched, so that the downward pulling force exerted by the connecting block one 14 on the two push-pull plates 21 is further increased, that is, the two pressing plates 8 are further pressed tightly against the workpiece, strengthening the stability of the workpiece. After the detection is completed, the cylinder 3 drives the connecting rod 4, the cross plate 5, the protective cover 6, and the inspection head 16 to move upward. The protective cover 6 is separated from the inspection table 1. The stretched spring one 18 drives the protective cover 6 to return to its original position. The pressing rod 7 returns to its original position and is separated from the moving plate 12. The stretched spring two 20 drives the connecting block one 14 to move upward until it returns to its original position, exerting an upward pushing force on the two push-pull plates 21, and the two pressing plates 8 can be pushed back to their original positions to realize the unlocking of the workpiece.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
