[0019] Next, the technical solutions of the present utility model will be described clearly and completely in conjunction with the attached Figures 1-3 Obviously, the described embodiments are some embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] An embodiment of the present application discloses a bolt fastener detection device. Referring to Figures 1-3 , it includes a bottom plate 1. A U-shaped frame 2 is fixedly connected to the top side of the bottom plate 1. A press body 3 is fixedly installed at the center of the top side of the U-shaped frame 2. A control panel body 4 is fixedly installed on the right side of the U-shaped frame 2. The control panel body 4 is linearly connected to the press body 3. A pressing cover 5 is placed on the top side of the bottom plate 1. A mold groove is opened at the center of the bottom side of the pressing cover 5. A limit die 6 is movably installed on the inner wall of the mold groove. Through holes are opened on the top sides of both the pressing cover 5 and the limit die 6. By setting the pressing cover 5 and the limit die 6, lift the pressing cover 5 upward, then place the threaded end of the bolt to be detected facing upward, and lower the pressing cover 5. At this time, the threaded end of the bolt will leak out from the through hole, and at the same time, the limit die 6 will fit against the outer surface of the knob end of the bolt, so as to limit the placed bolt to prevent it from shifting. Operate the control panel body 4 to input the counteracting strength value of the bolt itself to be qualified to control the press body 3 to start working. At this time, the press body 3 will perform extrusion detection on the placed bolt. When the input pressure value is reached, the press body 3 will stop working and reset. At this time, take out the placed bolt and observe whether it is deformed, so as to complete the detection work of the bolt. Compared with the application of multiple cylinders in the comparative document, in this case, the overall manufacturing cost of the equipment can be effectively reduced on the premise of achieving the same detection purpose, and the bolt can always be in the center position during the detection process, which is beneficial to popularization and use.

[0021] In this application, a ring groove is provided on the bottom side of the gland 5, and a magnetic ring 7 is fixedly installed on the inner wall of the ring groove. By setting the magnetic ring 7, the magnetic force generated by the magnetic ring 7 can be used to magnetically fix the placed limit die 6, and it is convenient to disassemble and replace limit dies 6 of different sizes, so as to be applicable to limiting bolts of different sizes. Compared with the comparative document, the applicable range can be further improved.

[0022] In this application, two vertical rods 8 are fixedly connected to the top side of the bottom plate 1, and the gland 5 is slidably sleeved with the two vertical rods 8. By setting the vertical rods 8, when the gland 5 moves up or down, the two vertical rods 8 cooperate with each other to make the gland 5 move in the vertical direction and avoid deviation.

[0023] In this application, two springs 9 are fixedly connected to the top side of the gland 5, and both of the two springs 9 are fixedly connected to the bottom side of the U-shaped frame 2. By setting the springs 9, after the gland 5 is lifted upward to complete the placement of the bolt, the restoring force generated by the contraction of the springs 9 can increase the reset speed of the gland 5 downward, thereby improving the convenience of use.

[0024] In this application, two handles 10 are fixedly connected to the front and rear sides of the gland 5, and the two handles 10 are symmetrically distributed. By setting the handles 10, the two handles 10 cooperate with each other to facilitate the worker to lift the gland 5 upward, thereby improving the convenience of operation.

[0025] The standard parts used in this utility model can all be purchased from the market. The special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machines, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0026] The implementation principle of a bolt fastener detection device according to an embodiment of the present application is as follows: When in use, the gland 5 is lifted upward, and then the threaded end of the bolt to be detected is placed with the opening facing upward. After the gland 5 is lowered, at this time, the threaded end of the bolt will leak out from the through hole, and at the same time, the limiting die 6 will fit against the outer surface of the knob end of the bolt, so as to limit the placed bolt and prevent it from shifting. The operator inputs the counter strength value of the bolt itself being qualified into the operation control panel body 4 to control the press body 3 to start working. At this time, the press body 3 will perform extrusion detection on the placed bolt. When the input pressure value is reached, the press body 3 stops working and resets. At this time, the placed bolt is taken out and observed for deformation, so as to complete the detection work of the bolt. Compared with the application of multiple cylinders in the comparative document, in this case, on the premise of achieving the same detection purpose, the overall manufacturing cost of the equipment can be effectively reduced, and the bolt can always be in the center position during the detection process, which is beneficial to popularization and use. By using the magnetic force generated by the magnetic ring 7, the placed limiting die 6 can be magnetically fixed, and it is convenient to disassemble and replace the limiting die 6 of different sizes, so as to be applicable to limiting bolts of different sizes. Compared with the comparative document, the applicable range can be further improved. When the gland 5 moves up or down, the two vertical rods 8 cooperate with each other to keep the gland 5 moving in the vertical direction and prevent it from shifting. When the gland 5 is lifted upward to complete the placement of the bolt, the resilience generated by the contraction of the spring 9 can increase the reset speed of the gland 5 downward, thereby improving the convenience of use. The two handles 10 cooperate with each other to facilitate the worker to lift the gland 5 upward, thereby improving the convenience of operation.
