Description

Technical Field

[0001] This utility model belongs to the field of welding joint technology, and in particular relates to a reinforcement device for welding joints of large 9Cr steel forgings. Background Technology

[0002] According to the published patent CN210615669U, a workbench and support legs fixed at the four corners of the bottom of the workbench are included. A rotating mechanism is rotatably provided at the center of the top of the workbench. Through the cooperation of a first screw, a second screw, a placement plate, a cover plate, and a movable arc plate, a steel-plastic composite pipe with a V-shaped groove in the middle is placed into the inner cavity of the placement plate. The steel-plastic composite pipe is fixedly installed on the placement plate with screws. One hand manually pushes the U-shaped frame to rotate while the other hand performs welding. This allows for continuous welding of the V-shaped ends and V-shaped grooves of two steel-plastic composite pipes, avoiding the need for manual welding on the other side of the workbench and improving the welding efficiency of the steel-plastic composite pipe. However, the following shortcomings still exist.

[0003] In the use of the above-mentioned equipment, some forgings may not be able to match the grooves on the surface of the placement plate due to their shape and size. Some forgings cannot be placed properly, which may cause the forgings to be displaced due to external forces during the subsequent welding process. Therefore, we propose a reinforcement device for welded joints of large 9Cr steel forgings. Summary of the Invention

[0004] The purpose of this utility model is to provide a reinforcement device for welded joints of large 9Cr steel forgings. By replacing the mechanism and clamping mechanism, it solves the problem that some forgings may not fit the groove on the surface of the placement plate due to their shape and size, and some forgings may not be properly placed, which may cause the forgings to be displaced by external force during the subsequent welding process.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a reinforcement device for welded joints of large 9Cr steel forgings, including a fixing plate, a support frame fixedly connected to the bottom outer wall of the fixing plate, and a replacement mechanism provided on the outer wall of the fixing plate.

[0007] The replacement mechanism includes a motor base, a motor fixedly connected to the outer wall of the motor base, a worm gear fixedly connected to the bottom output shaft of the motor via a coupling, a worm gear seat rotatably connected to the outer wall of the worm gear, the outer wall of the worm gear seat being fixedly connected to the bottom outer wall of a fixed plate, a transmission disc rotatably connected to the inner wall of the fixed plate, a plurality of transmission grooves being formed on the inner wall of the transmission disc, a plurality of fixing pins being slidably connected to the inner walls of the plurality of transmission grooves, a plurality of guide grooves being formed on the inner wall of the fixed plate, the inner walls of the plurality of guide grooves being slidably connected to the outer walls of the fixing pins, and a worm wheel fixedly connected to the bottom outer wall of the transmission disc, the outer wall of the worm wheel meshing with the outer wall of the worm gear.

[0008] Furthermore, the inner wall of the fixing plate is provided with an installation groove, the inner wall of the installation groove is slidably connected to a placement plate, the inner wall of the placement plate is provided with a plurality of fixing grooves, and the inner walls of the plurality of fixing grooves are slidably connected to the outer wall of the fixing pin.

[0009] Furthermore, the top outer wall of the fixing plate is provided with a clamping mechanism, the clamping mechanism including a base, the bottom outer wall of the base being fixedly connected to the top outer wall of the fixing plate.

[0010] Furthermore, an electric telescopic rod is fixedly connected to the top outer wall of the base, and a clamping seat is fixedly connected to the top outer wall of the electric telescopic rod.

[0011] Furthermore, a threaded rod is drivenly connected to the inner wall of the clamping seat, and a knob is fixedly connected to the top outer wall of the threaded rod.

[0012] Furthermore, the inner wall of the clamping seat is rotatably connected to several rotating rods, and the outer walls of the several rotating rods are fixedly connected to several clamps.

[0013] Furthermore, anti-slip pads are fixedly connected to the outer walls of several clamps, and several connecting rods are rotatably connected to the outer walls of the clamps.

[0014] Furthermore, a lifting plate is rotatably connected to the outer wall of several of the connecting rods, and the top outer wall of the lifting plate is rotatably connected to the bottom outer wall of the threaded rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting fixed pins, allows the motor to drive the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the transmission disc to rotate. The transmission disc causes several fixed pins to move away from each other. During this process, the fixed pins slide within the guide groove and the transmission groove, and eventually disengage from the fixed groove. The placement plate can then be lifted directly from the mounting groove. Subsequently, placement plates of different sizes and shapes can be reset and installed. This allows for quick and convenient replacement of placement plates for forgings of different shapes and sizes, ensuring that most forgings can be properly placed and preventing displacement of some forgings during welding due to mismatch between their shape and the placement plate.

[0017] 2. This utility model incorporates clamps. Rotating the knob counterclockwise causes the threaded rod to rotate, which in turn moves the threaded rod upwards. This upward movement of the threaded rod causes the lifting plate to move upwards, and the base causes several connecting rods to rotate. These connecting rods, in turn, cause the clamps to rotate. During rotation, the clamps engage anti-slip pads to adhere to the surface of the forging and clamp it securely. This provides a stable and comprehensive clamping of the forging located above, ensuring that the forging will not easily loosen due to external force during welding.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a reinforcement device for welded joints of large 9Cr steel forgings, including a fixing plate 1. A support frame 101 is fixedly connected to the bottom outer wall of the fixing plate 1. The support frame 101 mainly plays the role of fixing and limiting the fixing plate 1. The fixing plate 1 is fixed on the support frame 101. A replacement mechanism 2 is provided on the outer wall of the fixing plate 1.

[0029] The replacement mechanism 2 includes a motor base 201, with a motor 202 fixedly connected to its outer wall. A worm gear 203 is fixedly connected to the bottom output shaft of the motor 202 via a coupling. The motor 202 primarily provides kinetic energy to the worm gear 203. When the motor 202 starts, it drives the worm gear 203 to rotate simultaneously. A worm gear seat 204 is rotatably connected to the outer wall of the worm gear 203. The outer wall of the worm gear seat 204 is fixedly connected to the bottom outer wall of the fixing plate 1. A transmission disc 205 is rotatably connected to the inner wall of the fixing plate 1. Several transmission grooves 206 are formed on the inner wall of the transmission disc 205. The fixing plate 1 primarily limits the rotation of the transmission disc 205, ensuring that the transmission disc 205 can only rotate within the fixing plate 1. The transmission disc 205 rotates in a fixed position. Several fixed pins 207 are slidably connected to the inner walls of several transmission grooves 206. Several guide grooves 208 are provided on the inner wall of the fixed plate 1. The inner walls of the guide grooves 208 are slidably connected to the outer walls of the fixed pins 207. The guide grooves 208 mainly play a sliding limiting role for the fixed pins 207. The fixed pins 207 can only slide at a fixed angle within the guide grooves 208. A worm wheel 209 is fixedly connected to the bottom outer wall of the transmission disc 205. The outer wall of the worm wheel 209 meshes with the outer wall of the worm 203. The transmission disc 205 mainly plays a fixing limiting role for the worm wheel 209. When the worm wheel 209 rotates, it will drive the transmission disc 205 to rotate together.

[0030] The inner wall of the fixed plate 1 is provided with an installation groove 210. The inner wall of the installation groove 210 is slidably connected to a placement plate 211. The inner wall of the placement plate 211 is provided with several fixing grooves 212. The inner walls of the fixing grooves 212 are slidably connected to the outer wall of the fixing pin 207. The top outer wall of the fixed plate 1 is provided with a clamping mechanism 3. The clamping mechanism 3 includes a base 301. The bottom outer wall of the base 301 is fixedly connected to the top outer wall of the fixed plate 1. The top outer wall of the base 301 is fixedly connected to an electric telescopic rod 302. The top outer wall of the electric telescopic rod 302 is fixedly connected to a clamping seat 303. The installation groove 210 mainly serves to slide and limit the placement plate 211. The placement plate 211 can slide and move at a fixed angle within the installation groove 210.

[0031] A threaded rod 304 is drivenly connected to the inner wall of the clamping seat 303. A knob 305 is fixedly connected to the top outer wall of the threaded rod 304. Several rotating rods 306 are rotatably connected to the inner wall of the clamping seat 303. The clamping seat 303 mainly serves to limit the rotation of the rotating rods 306, allowing them to rotate only in fixed positions within the clamping seat 303. Several clamps 307 are fixedly connected to the outer walls of each of the rotating rods 306, and anti-slip devices are fixedly connected to the outer walls of each of the clamps 307. The pad 308 is made of rubber. When the anti-slip pad 308 comes into contact with the forging, it can generate sufficient friction to prevent displacement. The outer wall of the clamp 307 is rotatably connected to several connecting rods 309. The outer wall of the several connecting rods 309 is rotatably connected to the lifting plate 310. The top outer wall of the lifting plate 310 is rotatably connected to the bottom outer wall of the threaded rod 304. The lifting plate 310 mainly plays the role of limiting the rotation of the threaded rod 304. The threaded rod 304 can rotate in a fixed position on the lifting plate 310.

[0032] One specific application of this embodiment is:

[0033] When the operator needs to use the equipment, simply place the forging in the groove of the placement plate 211, and then place another forging between the clamps 307 on both sides of the lifting plate 310. Then, turn the knob 305 counterclockwise. The knob 305 will drive the threaded rod 304 to rotate, causing it to move upwards. This movement of the threaded rod 304 will cause the lifting plate 310 to move upwards, and the base 301 will drive several connecting rods 309 to rotate. Each connecting rod 309 will then drive the clamps 307 to rotate, and each clamp 307 will then drive the anti-slip pads 308 to adhere to the surface of the forging and clamp it securely. Then, activate the electric telescopic rod 302 to retract. The electric telescopic rod 302 will drive the clamping seat 303 to move downwards, which in turn will drive several rotating rods 306 to move downwards. Each rotating rod 306 will then drive several clamps 307 to move downwards, and each clamp 307 will then drive the anti-slip pads 308 to adhere to the surface of the forging and clamp it securely. The sliding pads 308 are displaced, and several anti-slip pads 308 will cause the fixed forging to descend and move downwards, and fit against the forging located in the placement plate 211. Finally, the two forgings can be directly welded. The groove of the placement plate 211 will fit against the surface of the lower forging to prevent it from shifting during the welding process. Before welding, the placement plate 211 can be replaced according to the different shapes of the forgings. Simply start the motor 202, and the motor 202 will drive the worm 203 to rotate. The worm 203 will drive the worm wheel 209 to rotate. The worm wheel 209 will drive the transmission disk 205 to rotate. The transmission disk 205 will drive several fixing pins 207 to move away from each other. During this period, several fixing pins 207 will slide in the guide groove 208 and the transmission groove 206. Several fixing pins 207 will disengage from the fixing groove 212. Then, the placement plate 211 can be lifted upwards from the mounting groove 210. Then, the placement plates 211 of different sizes and shapes can be reset and installed.
