Description

Technical Field

[0001] The utility model relates to the technical field of local spraying of bolts, in particular to a local spraying tooling for fastener bolts. Background Technique

[0002] As a spraying part with relatively high surface precision, bolts need to be locally sprayed during spraying.

[0003] In the existing method of local spraying of fastener bolts, generally, the parts of the bolts that do not need to be sprayed are wrapped with tin foil and then sprayed. After the spraying operation is completed, the tin foil is removed. In practice, the traditional manual spraying method is inefficient, and there are certain gaps easily generated in the packaging parts by manual operation. Moreover, the tin foil used as the packaging and sealing material is a disposable product, which is not environmentally friendly. Content of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems in the above background, and to propose a local spraying tooling for fastener bolts.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a local spraying tooling for fastener bolts, including a U-shaped frame. A plurality of through holes are evenly opened on the inner bottom surface of the U-shaped frame, and the size of the through holes is adapted to the outer diameter of the screw rod of the bolt. An auxiliary device is arranged on the side surface of the U-shaped frame. The auxiliary device includes a U-shaped plate, the U-shaped plate is fixedly installed on the side surface of the U-shaped frame, a threaded rod is rotatably connected between the inner walls at both ends of the U-shaped plate, and a runner is fixedly installed at one end port of the threaded rod. The setting of the runner plays the role of driving the threaded rod to rotate.

[0006] Preferably, vertical grooves are opened on the inner wall surface of the U-shaped plate, a moving plate is threadedly connected to the surface of the threaded rod, and a cover plate is fixedly installed on the side surface of the moving plate. The setting of the threaded rod plays the role of driving the moving plate to move inside the vertical groove.

[0007] Preferably, four positioning rods are fixedly installed on the bottom surface of the cover plate, and four positioning holes are opened on the surface of the U-shaped frame. The setting of the positioning rods and the positioning holes plays the role of making the fit between the cover plate and the U-shaped frame closer.

[0008] Preferably, a hanging device is arranged on the surface of the cover plate. The hanging device includes a storage groove, the storage groove is opened on the surface of the cover plate, a rotating rod is rotatably connected between the inner walls at both ends of the storage groove, a rotating plate is fixedly installed on the outer wall surface of the rotating rod, and a hanging ring is fixedly installed on the side surface of the rotating plate. The setting of the rotating rod and the rotating plate plays the role of making the hanging ring rotatable.

[0009] Preferably, a groove is formed on one side surface of the storage groove. A displacement plate is slidably connected inside the groove. A limiting rod is fixedly installed on the surface of the displacement plate. A plurality of limiting holes are annularly formed on the outer wall surface of the rotating rod. The arrangement of the limiting rod and the limiting holes has the effect of restricting the rotation of the rotating rod.

[0010] Preferably, a rectangular plate is fixedly installed on one inner wall surface of the storage groove. A spring is fixedly installed between the rectangular plate and the displacement plate. The arrangement of the spring has the effect of restricting the position of the displacement plate inside the groove.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] 1. In the present utility model, by providing an auxiliary device, when the device needs to be used, first pass the bolt through the inside of the through hole, so that the screw rod of the bolt is located below the through hole, and the screw head of the bolt is located on the inner bottom surface of the U-shaped frame. Then rotate the rotating wheel. The rotation of the rotating wheel drives the threaded rod to rotate. The rotation of the threaded rod drives the moving plate to move inside the vertical groove. The movement of the moving plate inside the vertical groove drives the cover plate to move. The movement of the cover plate also drives the positioning rod to move. When the position of the cover plate fits the top surface of the U-shaped frame, at this time, the positioning rod also inserts into the positioning hole. After the positioning rod and the positioning hole are inserted, stop rotating the rotating wheel. At this time, the screw rod of the bolt can be sprayed. During spraying, use the inner cavity formed between the cover plate and the U-shaped frame to cover the screw head of the screw rod, achieving the purpose of local spraying. Through the cooperation of the above structures, the efficiency is significantly improved compared with using tin foil packaging before, and it is more environmentally friendly.

[0013] 2. In the present utility model, by providing a hanging device, when it is necessary to conveniently spray the bolt, first slide the displacement plate, so that the displacement plate moves inside the groove. The movement of the displacement plate inside the groove will compress the spring, causing the spring to be compressed under force. At the same time, the movement of the displacement plate inside the groove also drives the limiting rod to move. The movement of the limiting rod causes it to move out of the inside of the limiting hole. The separation of the limiting rod and the limiting hole causes the rotating rod to lose its limit. At this time, the rotating rod can be rotated. The rotation of the rotating rod drives the rotating plate to rotate. The rotation of the rotating plate drives the hanging ring to rotate. When the hanging ring rotates to the vertical state, release the displacement plate. Use the resilience of the spring to make the limiting rod reinsert into the corresponding limiting hole to re-limit the rotation of the rotating rod. At the same time, the hanging ring in the vertical state can be directly hung on an external hook, and then spraying can be carried out. Through the cooperation of the above structures, the device can spray the bolt in a hanging manner, thereby improving the convenience of spraying. Description of the Drawings

[0020] In order to more clearly understand the above - mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a local spraying tooling for fastener bolts, including a U - shaped frame 1. A plurality of through - holes 2 are evenly formed in the inner bottom surface of the U - shaped frame 1, and the size of the through - holes 2 is adapted to the outer diameter of the screw rod of the bolt.

[0023] The following specifically describes the specific settings and functions of its auxiliary device 3 and hanging device 4.

[0024] In this embodiment: An auxiliary device 3 is provided on the side of the U - shaped frame 1. The auxiliary device 3 includes a U - shaped plate 31. The U - shaped plate 31 is fixedly installed on the side of the U - shaped frame 1, and a threaded rod 32 is rotatably connected between the inner walls at both ends of the U - shaped plate 31. One end port of the threaded rod 32 is fixedly installed with a rotating wheel 33.

[0025] In this embodiment, the setting of the rotating wheel 33 has the effect of driving the threaded rod 32 to rotate.

[0026] Specifically, vertical grooves 34 are formed on the inner wall surface of the U-shaped plate 31. A moving plate 35 is threadedly connected to the surface of the threaded rod 32, and a cover plate 36 is fixedly installed on the side surface of the moving plate 35.

[0027] In this embodiment, the setting of the threaded rod 32 has the effect of driving the moving plate 35 to move inside the vertical groove 34.

[0028] Specifically, four positioning rods 37 are fixedly installed on the bottom surface of the cover plate 36, and four positioning holes 38 are formed on the surface of the U-shaped frame 1. The settings of the positioning rods 37 and the positioning holes 38 have the effect of making the fit between the cover plate 36 and the U-shaped frame 1 more tight.

[0029] In this embodiment, a hanging device 4 is provided on the surface of the cover plate 36. The hanging device 4 includes a storage groove 401 formed on the surface of the cover plate 36. A rotating rod 402 is rotatably connected between the inner wall surfaces at both ends of the storage groove 401. A rotating plate 403 is fixedly installed on the outer wall surface of the rotating rod 402, and a hanging ring 404 is fixedly installed on the side surface of the rotating plate 403. When it is necessary to conveniently spray the bolt, first slide the displacement plate 406, so that the displacement plate 406 moves inside the groove 405. The movement of the displacement plate 406 inside the groove 405 will squeeze the spring 410, causing the spring 410 to be compressed under force. At the same time, the movement of the displacement plate 406 inside the groove 405 also drives the limit rod 407 to move. The movement of the limit rod 407 causes it to move out of the inside of the limit hole 408. The separation of the limit rod 407 and the limit hole 408 causes the rotating rod 402 to lose its limit. At this time, the rotating rod 402 can be rotated. The rotation of the rotating rod 402 drives the rotating plate 403 to rotate, and the rotation of the rotating plate 403 drives the hanging ring 404 to rotate. When the hanging ring 404 rotates to a vertical state, release the displacement plate 406, and use the resilience of the spring 410 to make the limit rod 407 re-insert into the corresponding limit hole 408 to re-limit the rotation of the rotating rod 402. At the same time, the hanging ring 404 in the vertical state can be directly hung on an external hook, and then spraying can be carried out. Through the cooperation of the above structures, the device can spray the bolt in a hanging manner, thereby improving the convenience of spraying.

[0030] Specifically, a groove 405 is formed on one side surface of the storage groove 401. A displacement plate 406 is slidably connected inside the groove 405. A limit rod 407 is fixedly installed on the surface of the displacement plate 406, and a plurality of limit holes 408 are annularly formed on the outer wall surface of the rotating rod 402.

[0031] In this embodiment, the settings of the limit rod 407 and the limit hole 408 have the effect of restricting the rotation of the rotating rod 402.

[0032] Specifically, a rectangular plate 409 is fixedly installed on the inner wall surface of one side of the storage groove 401, and a spring 410 is fixedly installed between the rectangular plate 409 and the displacement plate 406.

[0033] In this embodiment, the spring 410 functions to limit the position of the displacement plate 406 inside the groove 405.

[0034] Working principle: By setting the auxiliary device 3, when the device needs to be used, first pass the bolt through the inside of the through hole 2, so that the screw rod of the bolt is located below the through hole 2, and the screw head of the bolt is located on the inner bottom surface of the U-shaped frame 1. Then rotate the rotating wheel 33. The rotation of the rotating wheel 33 drives the threaded rod 32 to rotate. The rotation of the threaded rod 32 drives the moving plate 35 to move inside the vertical groove 34. The movement of the moving plate 35 inside the vertical groove 34 drives the cover plate 36 to move. The movement of the cover plate 36 also drives the positioning rod 37 to move. When the position of the cover plate 36 fits the top surface of the U-shaped frame 1, at this time, the positioning rod 37 also inserts into the positioning hole 38. After the positioning rod 37 and the positioning hole 38 are inserted, stop rotating the rotating wheel 33. At this time, the screw rod of the bolt can be sprayed. During spraying, the inner cavity formed between the cover plate 36 and the U-shaped frame 1 is used to cover the screw head of the screw rod, achieving the purpose of local spraying. Through the cooperation of the above structures, the efficiency is significantly improved compared with using tin foil packaging before, and it is more environmentally friendly. When it is necessary to facilitate the spraying of the bolt, first slide the displacement plate 406, so that the displacement plate 406 moves inside the groove 405. The movement of the displacement plate 406 inside the groove 405 will compress the spring 410, causing the spring 410 to be compressed under force. At the same time, the movement of the displacement plate 406 inside the groove 405 also drives the limiting rod 407 to move. The movement of the limiting rod 407 causes it to move out of the inside of the limiting hole 408. The separation of the limiting rod 407 and the limiting hole 408 causes the rotating rod 402 to lose its limit. At this time, the rotating rod 402 can be rotated. The rotation of the rotating rod 402 drives the rotating plate 403 to rotate. The rotation of the rotating plate 403 drives the hanging ring 404 to rotate. When the hanging ring 404 rotates to a vertical state, release the displacement plate 406. Use the resilience of the spring 410 to make the limiting rod 407 reinsert into the corresponding limiting hole 408 to re-limit the rotation of the rotating rod 402. At the same time, the hanging ring 404 in the vertical state can be directly hung on an external hook, and then spraying can be carried out. Through the cooperation of the above structures, the device can spray the bolt in a suspended manner, thereby improving the convenience of spraying.
