[0002] In the field of mechanical assembly and manufacturing, the combined bolt is widely used in various equipment and structures due to its compact structure and convenient installation. However, since the bolt head integrates a variety of complex gasket structures, while these gaskets increase functionality, they also greatly change the overall geometric shape and weight distribution of the bolt, making it difficult to directly apply traditional detection methods for bolt concentricity, resulting in generally low efficiency in detecting the concentricity of combined bolts at present. Therefore, it is necessary to solve the above technical problems. Summary of the Invention
[0003] The purpose of the embodiments of this application is to provide a concentricity detection device for a three-piece hexagon flange bolt to solve the technical problem of low efficiency in detecting the concentricity of three-piece hexagon flange bolts in the prior art.
[0004] To achieve the above purpose, the technical solution adopted in this application is: to provide a concentricity detection device for a three-piece hexagon flange bolt, used to detect the concentricity of a target three-piece hexagon flange bolt, where the three-piece hexagon flange bolt includes a hexagon flange, a screw rod, and a spring washer and a plain washer respectively sleeved on the screw rod. The concentricity detection device for the three-piece hexagon flange bolt includes:
[0005] A base with a control system disposed inside;
[0006] A top plate connected to the base through columns and spaced relative to the base;
[0007] A die holder connected to the columns and located between the base and the top plate, and a plurality of through holes adapted to the hexagon flange and arranged in a hexagon are formed on the die holder;
[0008] Detection components, a plurality of groups corresponding to the number of through holes are respectively provided on the base and the top plate. The detection components include a laser emitter capable of emitting laser towards the center of the through hole and a camera facing the die holder and used for taking images. The laser emitter and the camera are both communicatively connected to the control system and the laser emission direction of the laser emitter is coaxial with the through hole.
[0009] Optionally, the die holder includes a body and a movable block detachably connected to the body;
[0010] The body is connected to the columns, and all the through holes are provided on the movable block.
[0011] Optionally, a receiving cavity for receiving the movable block is formed on the body;
[0012] The accommodating cavity has an opening along the thickness direction of the body for the movable block to be separated from the accommodating cavity, and the body and the movable block are connected through friction damping.
[0013] Optionally, a guide cavity connected to the accommodating cavity is formed on the body;

[0016] The beneficial effect of the concentricity detection device for three-combination bolts with hexagonal flange provided by the present application is that: compared with the prior art, in the concentricity detection device for three-combination bolts with hexagonal flange provided by the present application, a plurality of detection components are respectively arranged on the base and the top plate, and a control system connected to the laser emitter and the camera is arranged inside the base. Since the laser emitted by the laser emitter is directed toward the center of the through hole and the direction of the laser is coaxial with the through hole, when the target three-combination bolt with hexagonal flange is installed into the through hole through its hexagonal flange, the laser emitters located on the top plate and the base can form focused light spots on the end faces of the hexagonal flange and the screw rod that are away from each other, respectively, and the camera facing the mold base can take the end face image of the hexagonal flange with the laser focus and the end face image of the screw rod with the laser focus and send them to the control system for analysis, and the control system can efficiently detect the concentricity of the target three-combination bolt with hexagonal flange by quickly analyzing the distance that the laser focus deviates from the center of the through hole, which is far superior to the prior art.

[0028] Please refer to togetherFigures 1 to 5 , a concentricity detection device for a hexagonal flange three-combination bolt provided in an embodiment of the present application will now be described. The concentricity detection device for the hexagonal flange three-combination bolt provided in this embodiment is used to detect the concentricity of a target hexagonal flange three-combination bolt, and the target hexagonal flange three-combination bolt includes a hexagonal flange 201, a screw rod 202, and a spring washer 203 and a flat washer 204 respectively sleeved on the screw rod 202. Specifically, the concentricity detection device for the hexagonal flange three-combination bolt includes a base 101, a top plate 102, a die holder 104, and a detection assembly. Among them:
[0029] A control system (not shown in the drawings) is provided inside the base 101; the top plate 102 is connected to the base 101 through a column 103 and is spaced relative to the base 101; the die holder 104 is connected to the column 103 and is located between the base 101 and the top plate 102. A plurality of through holes 105 adapted to the hexagonal flange 201 and arranged in a hexagonal shape are formed on the die holder 104; a plurality of groups corresponding to the number of the through holes 105 are respectively provided on the base 101 and the top plate 102 for the detection assembly. The detection assembly includes a laser emitter 106 capable of emitting laser towards the center of the through hole 105 and a camera 107 facing the die holder 104 and used for taking images. Both the laser emitter 106 and the camera 107 are communicatively connected to the control system, and the laser emission direction of the laser emitter 106 is coaxial with the through hole 105.
[0030] According to the above structure provided in this embodiment, in the concentricity detection device for the hexagonal flange three-combination bolt provided in this embodiment, several groups of detection components are respectively arranged on the base 101 and the top plate 102. A control system communicatively connected to the laser emitter 106 and the camera 107 is arranged inside the base 101. After the detection device is manufactured, first, the laser emitters 106 on the base 101 and the top plate 102 are calibrated so that the laser emitted by the laser emitter 106 is directed towards the center of the through hole 105 and the laser direction is coaxial with the through hole 105. Since the laser emitted by the laser emitter 106 is directed towards the center of the through hole 105 and the laser direction is coaxial with the through hole 105, when the target hexagonal flange three-combination bolt is inserted into the through hole 105 through its hexagonal flange 201, specifically, when installing, the hexagonal flange 201 is inserted into the through hole 105 and the screw rod 202 is directed towards the top plate 102. At this time, since the hexagonal outer wall of the hexagonal flange 201 cooperates with the through hole 105 and the conical arc surface of the flange cooperates with the orifice of the through hole 105 to complete self-positioning, then the laser emitter 106 is turned on. In this way, the laser emitters 106 on the top plate 102 and the base 101 can respectively form focused light spots on the end faces where the hexagonal flange 201 and the screw rod 202 are away from each other. The camera 107 facing the mold base 104 can capture the end face image of the hexagonal flange 201 with the laser focus and the end face image of the screw rod 202 with the laser focus and send them to the control system for analysis. The control system can efficiently detect the concentricity of the target hexagonal flange three-combination bolt by quickly analyzing the distance between the laser focus and the center of the through hole 105, which is far better than the prior art. In addition, since there are multiple through holes 105 provided on the mold base 104, it can be used for the concentricity detection of multiple target hexagonal flange three-combination bolts at one time, which is beneficial to further improving the concentricity detection efficiency of the concentricity detection device for the hexagonal flange three-combination bolt in this embodiment.
[0031] In another embodiment of the present application, please refer to Figures 1 to 5 , the mold base 104 includes a main body 108 and a movable block 109 detachably connected to the main body 108; the main body 108 is connected to the column 103, and all the through holes 105 are arranged on the movable block 109. According to the above structure provided in this embodiment, different sizes of through holes 105 can be replaced by connecting different movable blocks 109 to the main body 108, which is beneficial to significantly improving the application range of the concentricity detection device for the hexagonal flange three-combination bolt in this embodiment.
[0032] In another embodiment of the present application, please refer to Figures 1 to 5A receiving chamber 110 for receiving a movable block 109 is formed on the body 108; the receiving chamber 110 has an opening along the thickness direction of the body 108 for the movable block 109 to be separated from the receiving chamber 110, and the body 108 and the movable block 109 are connected by friction damping. Specifically, the inner wall of the receiving chamber 110 has a set slope, so that the large opening end of the receiving chamber 110 faces the top plate 102, and the preferred slope is 0.5-1.5 degrees, and further preferably 1 degree; similarly, the surface of the movable block 109 that cooperates with the receiving chamber 110 is also set to the same slope, so that when the movable block 109 is placed in the receiving chamber 110 from above, the friction damping increases as it goes down, and finally it is stably supported. Conversely, when it needs to be disassembled, it can be easily taken out by pushing the movable block 109 upward. According to the above structure provided in this embodiment, the main body 108 can effectively improve the connection efficiency between the movable block 109 and the main body 108 by providing the accommodating cavity 110 adapted to the movable block 109. In addition, the movable block 109 and the accommodating cavity 110, which are adapted to each other in shape, can also better ensure that the position of the through hole 105 corresponds to the detection component, which is conducive to further improving the concentricity detection efficiency of the hexagonal flange three-combination bolt concentricity detection device in this embodiment.
[0033] In another embodiment of the present application, please refer to Figures 1 to 5 A guide cavity 111 connected to the accommodating cavity 110 is formed on the body 108, and the guide cavity 111 extends along the thickness of the body 108 and is provided for the edge of the movable block 109 to extend into. According to the above structure provided in this embodiment, the guide cavity 111 is provided on the body 108, which can significantly reduce the difficulty of installing the movable block 109 into the accommodating cavity 110, which is conducive to further improving the concentricity detection efficiency of the hexagonal flange three-combination bolt concentricity detection device in this embodiment.
[0034] In another embodiment of the present application, please refer to Figures 1 to 5 The detection component also includes a display screen 112 that is communicatively connected to the control system, and the display screen 112 is disposed on a side of the top plate 102 away from the base 101. According to the above structure provided in this embodiment, the display screen 112 can display the concentricity detection results of different hexagonal flange three-combination bolts at positions corresponding to each through hole 105, which is conducive to the operator to quickly obtain the concentricity detection results and further improve the concentricity detection efficiency of the hexagonal flange three-combination bolt concentricity detection device in this embodiment.
[0035] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
