Description

Technical Field

[0001] This utility model relates to the field of pipe fitting fixing and processing technology, specifically a fixing device for processing large-diameter pipe fittings. Background Technology

[0002] In modern industry, large-diameter pipe fittings occupy an important position in various pipeline systems due to their ability to transport large-flow media. At the same time, during the production and processing of large-diameter pipe fittings, it is necessary to limit and fix the large-diameter pipe fittings in order to carry out the size cutting or drilling of installation holes.

[0003] In existing technologies, when fixing and positioning large-diameter pipe fittings for subsequent cutting and drilling operations, the large-diameter pipe fittings present numerous challenges during processing due to their significant weight. Precise positioning is difficult, leading to displacement and vibration during processing, which affects processing accuracy and surface quality. Furthermore, it results in low clamping efficiency, increased processing auxiliary time, and reduced production efficiency. Therefore, we propose a fixing device for processing large-diameter pipe fittings. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for processing large-diameter pipe fittings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for processing large-diameter pipe fittings, comprising a base plate, two L-shaped plates fixedly connected to the top of the base plate, an installation groove provided on the top of the base plate, a motor fixedly connected inside the installation groove, a rotating rod fixedly connected to the output end of the motor, a worm gear fixedly connected to the outside of the rotating rod, two limiting rods fixedly connected to the adjacent side of the two L-shaped plates, two connecting blocks slidably connected to the outside of the two limiting rods, threaded rods threadedly connected inside the connecting blocks, a worm gear fixedly connected to the adjacent side of the two threaded rods, a clamping block fixedly connected to the top of the connecting blocks, a connecting block 2 fixedly connected to the top of the clamping block, an anti-detachment component provided on the outside of the L-shaped plates, a limiting component installed inside the base plate, and a support component slidably connected to the top of the base plate.

[0006] The base plate has multiple support columns fixedly connected to its bottom, and two columns fixedly connected to the top right side of the base plate. An arc-shaped placement plate is fixedly connected to the top of the two columns.

[0007] The anti-detachment component has a sliding connection of connecting post one inside, a sliding connection of connecting post two inside connecting post one, and a stop block fixedly connected to the outside of connecting post two.

[0008] The limiting assembly includes a motor 2 fixedly connected inside, a rotating rod 2 fixedly connected to the output end of the motor 2, a conical block fixedly connected to the top of the rotating rod 2, a connecting plate fixedly connected to the outside of the conical block, two rotating shafts 1 rotatably connected inside the connecting plate, a rotating plate fixedly connected to the outside of the rotating shafts 1, a rotating shaft 2 fixedly connected inside the rotating plate, an arc-shaped limiting block rotatably connected to the bottom of the rotating shafts 2, two sliders fixedly connected to the bottom of the arc-shaped limiting block, two fixed plates fixedly connected to the top of the base plate, and two sliding grooves opened inside the fixed plates.

[0009] The bottom plate has a sliding groove at the top, and two columns are fixedly connected to the top of the support component. An arc-shaped placement plate is fixedly connected to the top of the two columns.

[0010] The threaded rod is externally rotatably connected inside the L-shaped plate, and the worm gear and the worm are meshed together.

[0011] Among them, connecting post one is fixedly connected to the outside of connecting block two, and connecting post two is slidably connected to the inside of the anti-detachment component.

[0012] This utility model has at least the following beneficial effects:

[0013] In use, during the pipe fixing process, after adjusting the distance between the first and second arc-shaped placement plates according to the pipe length, the pipe is placed on top of both. The motor of the limiting component is then activated, driving the conical block to rotate. The rotating plate and the second rotating shaft pull the arc-shaped limiting block, achieving automatic clamping and limiting of both sides of the pipe, completing the initial fixing. Subsequently, the first motor drives the worm gear and threaded rod to rotate, causing the first connecting block to move along the limiting rod, further clamping the pipe with the clamping block. This dual fixing mechanism effectively prevents the pipe from shifting during processing, ensuring processing accuracy. Simultaneously, the support component can slide freely within the sliding groove. By adjusting the positions of the second column and the second arc-shaped placement plate, the distance between the two arc-shaped placement plates can be flexibly shortened or lengthened, easily adapting to large-diameter pipes of different lengths. This breaks through the limitations of traditional equipment on pipe size, reduces processing limitations caused by single equipment specifications, improves equipment versatility and processing efficiency, and ensures the stability of the processing process. It is suitable for the efficient and precise processing of various large-diameter pipes, providing reliable support for industrial production. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a fixing device for processing large-diameter pipe fittings, including a base plate 1, two L-shaped plates 2 fixedly connected to the top of the base plate 1, an installation groove 201 opened on the top of the base plate 1, a motor 202 fixedly connected inside the installation groove 201, a rotating rod 203 fixedly connected to the output end of the motor 202, a worm gear 204 fixedly connected to the outside of the rotating rod 203, and two limiting rods 205 fixedly connected to the adjacent side of the two L-shaped plates 2. The sliding connection consists of two connecting blocks 206. A threaded rod 207 is threaded inside connecting block 206. A worm gear 208 is fixedly connected to the adjacent side of the two threaded rods 207. A clamping block 209 is fixedly connected to the top of connecting block 206, and a connecting block 2010 is fixedly connected to the top of clamping block 209. An anti-detachment component 3 is provided on the outside of the L-shaped plate 2. A limit component 4 is installed inside the base plate 1, and a support component 5 is slidably connected to the top of the base plate 1. A motor 202 is installed inside the starting mounting slot 201. The motor 202 drives the rotating rod 203 to rotate, which in turn drives the worm wheel 204 to rotate. The worm wheel 204 meshes with the worm gear 208. When the worm wheel 204 rotates, it drives the worm gear 208 to rotate, which in turn drives the threaded rod 207 fixedly connected to it to rotate. Under the limiting action of the L-shaped plate 2, the connecting block 206 outside the threaded rod 207 moves towards the worm gear 208 under the guidance of the limiting rod 205. The connecting block 206 drives the clamping block 209 at the top to move towards the pipe fitting, clamping the pipe fitting. During the clamping process, the connecting block 2010 cooperates with the anti-detachment component 3 through the connecting post 301, the connecting post 302, and the stop block 303 to prevent the clamping block 209 from falling off under force, ensuring that the pipe fitting is firmly clamped, preventing displacement during processing, and ensuring processing accuracy.

[0022] Multiple support columns 101 are fixedly connected to the bottom of the base plate 1, and two upright columns 102 are fixedly connected to the top right side of the base plate 1. An arc-shaped placement plate 103 is fixedly connected to the top of the two upright columns 102. The multiple support columns 101 are fixedly connected to the bottom of the base plate 1 and are evenly distributed to ensure the stability of the device, transfer the weight of the base plate 1 and the components fixed on it to the ground, and prevent the device from shaking or shifting during use.

[0023] The anti-detachment component 3 has a connecting column 301 internally slidably connected to it, a connecting column 302 internally slidably connected to it, and a stop block 303 externally fixedly connected to the connecting column 302. The connecting column 301 is externally fixedly connected to the connecting block 2010, and the connecting column 302 is externally slidably connected to the inside of the anti-detachment component 3. The anti-detachment component 3 is set outside the L-shaped plate 2 and has a connecting column 301 internally slidably connected to it. It is used to prevent the clamping block 209 from falling off due to force during the clamping of the pipe fitting, thereby enhancing the safety and reliability of the clamping mechanism.

[0024] The limiting component 4 has a motor 401 fixedly connected inside, a rotating rod 402 fixedly connected to the output end of the motor 401, a conical block 403 fixedly connected to the top of the rotating rod 402, a connecting plate 404 fixedly connected to the outside of the conical block 403, two rotating shafts 405 rotatably connected inside the connecting plate 404, a rotating plate 406 fixedly connected to the outside of the rotating shafts 405, a rotating shaft 407 fixedly connected inside the rotating plate 406, an arc-shaped limiting block 408 rotatably connected to the bottom of the rotating shafts 407, two sliders 409 fixedly connected to the bottom of the arc-shaped limiting block 408, and two fixing plates 4010 fixedly connected to the top of the base plate 1. The fixing plates 4010 have two grooves 4011 inside. When the conical block 403 rotates, it pushes the rotating plate 406 on the connecting plate 404 to rotate around the rotating shafts 405. The rotating plate 406 pulls the arc-shaped limiting block 408 through the rotating shafts 407. The slider 409 at the bottom of the arc-shaped limiting block 408 slides in the groove 4011 of the fixing plate 4010. The two arc-shaped limiting blocks 408 move to both sides of the pipe fitting to clamp and limit the outer sides of the pipe fitting, thus completing the initial fixation of the pipe fitting and ensuring that the pipe fitting is in the correct position before the subsequent clamping operation.

[0025] The top of the base plate 1 is provided with a sliding groove 501. The top of the support component 5 is fixedly connected to two columns 502, and the top of the two columns 502 is fixedly connected to an arc-shaped placement plate 503. According to the length of the pipe fitting, the sliding support component 5 moves in the sliding groove 501, causing the columns 502 and the arc-shaped placement plate 503 to slide or move away from the arc-shaped placement plate 103 on the top of the base plate 1, adjusting the distance between the arc-shaped placement plate 503 and the arc-shaped placement plate 103 to adapt to the length of the pipe fitting.

[0026] The threaded rod 207 is externally rotatably connected to the inside of the L-shaped plate 2, and the worm gear 204 is externally meshed with the worm 208. The threaded rod 207 is threadedly connected to the inside of the connecting block 206, with one end fixedly connected to the worm 208 and rotatably connected to the inside of the L-shaped plate 2. Driven by the worm 208, it rotates, and through threaded transmission, the connecting block 206 moves along the limiting rod 205, thereby adjusting the position of the clamping block 209 and clamping or releasing the pipe fitting.

[0027] The working principle of this utility model is as follows: When processing large-diameter pipe fittings, it is only necessary to first adjust the distance between the arc-shaped placement plate 2 503 and the arc-shaped placement plate 1 103 according to the length of the pipe fitting. Then, place one side of the pipe fitting on the top of the arc-shaped placement plate 1 103 and the other side of the pipe fitting on the top of the arc-shaped placement plate 2 503. At this time, the limiting component 4 is activated, so that the motor 2 401 inside the limiting component 4 drives the conical block 403 to rotate through the rotating rod 2 402. When the conical block 403 rotates, the rotating plate 406 drives the rotating shaft 2 407 to pull the arc-shaped limiting block 408. This allows the two arc-shaped limiting blocks 408 to slide inside the fixing plate 4010 for limiting while clamping and limiting the outer sides of the pipe fitting for initial fixation.

[0028] After the limiting component 4 has limited the pipe fitting, the motor 202 inside the mounting slot 201 needs to be started. The motor 202 will drive the rotating rod 203 to rotate, and the worm gear 204 will drive the worm 208 to rotate. The worm 208 will then drive the threaded rod 207 to rotate. As the threaded rod 207 rotates, it will be limited by the L-shaped plate 2. The connecting block 206 outside the threaded rod 207 will move towards the worm 208 while being limited by the limiting rod 205. This will cause the clamping block 209 at the top to clamp and fix the pipe fitting, preventing the pipe fitting from shifting during processing.

[0029] Example 2

[0030] Please see Figure 1 and Figure 4 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that when placing pipes of different lengths, the support component 5 only needs to be slid inside the sliding groove 501. Then, the support component 5, together with the second column 502 and the second arc-shaped placement plate 503, slides from the top of the base plate 1 toward the first arc-shaped placement plate 103, thereby shortening the length between the second arc-shaped placement plate 503 and the first arc-shaped placement plate 103, so that pipes of different lengths can be placed.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
