Description

Technical Field

[0001] This utility model belongs to the technical field of clamping devices, and in particular relates to a movable welding clamping device. Background Technology

[0002] A portable welding clamping device is an auxiliary tool specifically designed for welding operations. It typically features a movable base or wheeled structure, facilitating flexible movement between different welding stations. It is also equipped with an adjustable clamping mechanism that can stably clamp and position the workpiece according to its shape, size, and welding process requirements, ensuring the workpiece remains in place during welding, thus improving welding accuracy and quality. Furthermore, the device generally includes portable operating components, balancing ease of movement with clamping reliability. It is suitable for various welding scenarios and can improve the efficiency and flexibility of welding operations.

[0003] Existing welding clamping devices have simple clamping structures, making it difficult to adapt to different workpiece sizes, shapes, and process requirements. This results in unstable clamping, causing workpieces to shake and shift during welding, affecting welding accuracy. In addition, the clamping devices are usually fixed in a certain position, which is not flexible and makes it difficult to move them flexibly according to actual needs. Utility Model Content

[0004] The purpose of this utility model is to provide a movable welding clamping device. By setting a clamping part, it solves the problem that it is difficult to adapt to the size, shape and process requirements of different workpieces, resulting in unstable clamping, easy shaking and displacement of the workpiece during welding, which affects the welding accuracy. At the same time, the clamping device is usually fixed in a certain position, with poor flexibility and is not convenient to move flexibly according to actual needs.

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

[0006] This utility model relates to a movable welding clamping device, comprising a support plate, and further comprising: a support part mounted on the support plate for connecting the device; a clamping part disposed on the support part for clamping the workpiece to be welded; and a moving part mounted on the support part for moving the device. When the workpiece to be welded is placed on the clamping part, the clamping part clamps and fixes it to facilitate welding operations. Simultaneously, during the welding process, the moving part can drive the device to move, thereby making the welding process more convenient and efficient.

[0007] Furthermore, the support unit includes a speed regulator fixedly connected to the top of the support plate. A support frame is fixedly connected to the top plate of the support plate, and two bearings are provided on the support frame. Rotary rods are rotatably connected to the two bearings. The speed regulator can adjust the speed of the clamping unit, so that when clamping the welding workpiece, it can accurately control the clamping speed and force according to the workpiece material, size and process requirements, avoid damaging the workpiece, ensure fast and stable clamping under different working conditions, and improve welding accuracy and efficiency.

[0008] Furthermore, the clamping part includes a clamping assembly mounted on a support frame for clamping the workpiece to be welded; and a driving assembly mounted on the support frame for providing power to the clamping assembly; wherein, after the driving assembly is activated, the driving assembly can transmit power to the clamping assembly, thereby causing the clamping assembly to clamp and fix the workpiece to be welded, so as to facilitate the welding operation on the workpiece.

[0009] Furthermore, the movable part includes a movable component mounted on a support plate to enable the device to move; and a fixing component mounted on the movable component to limit the movement of the movable component; wherein, the fixing component allows for flexible adjustment of the leg angles of the movable component, thereby enabling adjustment of the device height.

[0010] Furthermore, the clamping assembly includes a worktable fixedly connected to the top of the support frame. The rotating rod passes through the worktable and is rotatably connected to it. An arc-shaped groove turntable is sleeved on the outer wall of the rotating rod. Several slide rails are fixedly connected to the worktable. Slider blocks are slidably connected to the outer surfaces of the slide rails. A lever is fixedly connected to the top of each slider. The tops of the levers extend into the arc-shaped groove turntable and are slidably connected to it. Clamping components are provided on the sliders. When the rotating rod drives the arc-shaped groove turntable to rotate, the arc-shaped groove turntable slides against the levers on the sliders. Therefore, during rotation, the arc-shaped groove turntable can drive the sliders and the clamping components on the sliders to converge towards the center through the levers, thereby clamping the welded workpiece.

[0011] Furthermore, the drive assembly includes a motor sleeve fixedly connected to the back of the support frame, on which a motor is mounted. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. Both the rotating shaft and the outer wall of the rotating rod are fitted with pulleys, and belts are wound around the outer walls of the two pulleys. When the motor is started, the motor drives the rotating shaft to rotate. At this time, the pulley on the rotating shaft is linked with the pulley on the outer wall of the rotating rod via the belt, thereby driving the rotating rod and the arc-shaped groove turntable on it to rotate synchronously with the rotating shaft.

[0012] Furthermore, the movable component includes two fixed frames fixedly connected to the bottom of the support plate. Each of the two fixed frames has two support legs hinged to it. Several support legs are rotatably connected to casters at their ends away from the fixed frames. Several support legs are hinged to connecting rods, and several connecting rods are hinged to connecting plates at their ends away from the support legs. When the multiple support legs rotate relative to the two fixed frames, the connecting rods on the support legs will cooperate with the connecting plates, so that the connecting plates can drive the multiple support legs to move synchronously through the connecting rods, which facilitates the synchronous adjustment of the support legs.

[0013] Furthermore, the fixing assembly includes a screw fixedly connected to the bottom of the support plate. The screw passes through the connecting plate and is slidably connected to the connecting plate. A manual knob is threaded onto the outer wall of the screw, and a spring is wound around the outer wall of the screw. One end of the spring is fixedly connected to the support plate, and the other end of the spring is fixedly connected to the connecting plate. Rotating the manual knob on the outer wall of the screw allows the connecting plate to move under the push of the spring. When the multiple legs connected to the connecting plate sway, the spring, the connecting plate, and the screw cooperate to reduce swaying.

[0014] Furthermore, the clamping component includes several sliding grooves formed on the top of the workbench, with sliding rods fixedly connected to the top of each of the sliding blocks, and the sliding rods extending out of the sliding grooves and slidably connected to the sliding grooves, and clamps fixedly connected to the top of each of the sliding rods; wherein, when the arc-shaped groove turntable rotates, it contacts the actuating rods on the multiple sliding blocks, causing the sliding blocks to move, thereby causing the sliding rods and the clamps on them to converge towards the center, thus completing the fixation of the welded part.

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

[0016] 1. By setting up a clamping part, the workpiece to be welded can be placed on the worktable during use. Then, the motor is started, and the motor drives the rotating shaft to rotate. At this time, the pulley on the rotating shaft is linked with the pulley on the outer wall of the rotating rod through the belt, thereby driving the rotating rod and the arc-shaped groove turntable on it to rotate synchronously with the rotating shaft. When the arc-shaped groove turntable rotates, because the arc-shaped groove turntable slides against the actuating rods on multiple sliders, the arc-shaped groove turntable can drive multiple sliders to move through the actuating rods during the rotation process. This causes the slider and its clamps to converge towards the center, completing the fixation of the welded part. Through this setting, adaptive clamping of workpieces of different sizes can be achieved, effectively avoiding workpiece shaking and displacement caused by unstable clamping, and significantly improving the stability and welding accuracy of the welding process.

[0017] 2. By incorporating a movable section, the clamps on the device can be easily moved using multiple casters on the outriggers, significantly improving ease of use. To adjust the device height, simply turn the manual knob on the outer wall of the screw. Under the spring force, the connecting plate will move downwards. Since the connecting plate is hinged to multiple connecting rods, and the other end of the connecting rods is hinged to the rotatable outriggers of the fixed frame, the outriggers will drive the casters to adjust the height synchronously as the connecting plate moves, through the transmission of the connecting rods. In addition, the connecting plate can slide on the screw and be pushed by the spring. When the outriggers sway due to uneven ground or external impact, the springs can absorb the impact force through elastic deformation, effectively reducing the sway amplitude and ensuring stable operation of the device.

[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

[0027] 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.

[0028] Please see Figure 1-5 As shown, this utility model is a movable welding clamping device, including a support plate 111, and further including: a support part 1, which is mounted on the support plate 111 and serves to connect the device; a clamping part 2, which is disposed on the support part 1 and is used to clamp the workpiece to be welded; and a moving part 3, which is mounted on the support part 1 and is used to move the device; wherein, after the workpiece to be welded is placed on the clamping part 2, the clamping part 2 can clamp and fix it to facilitate the welding operation of the workpiece, and at the same time, during the welding process, the moving part 3 can drive the device to move, thereby making the welding process of the workpiece more convenient and efficient.

[0029] The clamping part 2 includes a clamping assembly 21, which is mounted on the support frame 113 for clamping the welding workpiece; and a driving assembly 22, which is mounted on the support frame 113 for providing power to the clamping assembly 21. When the driving assembly 22 is activated, it transmits power to the clamping assembly 21, thereby clamping and fixing the welding workpiece thereon to facilitate welding operations. The clamping assembly 21 includes a worktable 211 fixedly connected to the top of the support frame 113, with a rotating rod 115 passing through the worktable 211. The rotating rod 115 is rotatably connected to the worktable 211. An arc-shaped groove turntable 212 is fitted onto the outer wall of the rotating rod 115. Several slide rails 213 are fixedly connected to the worktable 211. Sliding sliders 214 are slidably connected to the outer surfaces of each slide rail 213. A lever 215 is fixedly connected to the top of each sliding slider 214. The tops of the levers 215 extend into the arc-shaped groove turntable 212 and are slidably connected to it. Clamping elements are provided on the sliding sliders 214. When the rotating rod 115 drives the arc-shaped groove turntable 212 to rotate, the arc-shaped groove turntable 212 and the multiple sliding sliders 214... The actuating levers 215 on 14 slide against each other, so during rotation, the arc-shaped groove turntable 212 can drive multiple sliders 214 and clamping parts on the sliders to converge towards the center through the actuating levers 215, thereby clamping the welding workpiece. The drive assembly 22 includes a motor sleeve 221 fixedly connected to the back of the support frame 113. A motor 222 is fitted on the motor sleeve 221. The output shaft of the motor 222 is fixedly connected to a rotating shaft 223 through a coupling. Pulleys 224 are fitted on the outer walls of both the rotating shaft 223 and the rotating rod 115. A belt 225 is wound around the outer walls of the two pulleys 224. After the motor 222 is started, the motor drives the rotating shaft 223 to rotate. At this time, the pulley 224 on the rotating shaft is linked with the pulley 224 on the outer wall of the rotating rod 115 through the belt 225, thereby driving the rotating rod 115 and the arc-shaped groove turntable 212 on it to rotate synchronously with the rotating shaft 223. The clamping component includes several sliding grooves 216 opened on the top of the worktable 211. The top of several sliders 214 is fixedly connected with a sliding rod 217. Several sliding rods 217 extend to the outside of the sliding grooves 216 and are slidably connected to the sliding grooves 216. The top of several sliding rods 217 is fixedly connected with a clamp 218.When the arc-shaped groove turntable 212 rotates, it contacts the actuating rods 215 on multiple sliders 214, causing the sliders 214 to move. This causes the slider 217 and its clamps 218 to converge towards the center, thus fixing the welded parts. By providing the clamping part 2, the workpiece to be welded can be placed on the worktable 211 during use. Then, the motor 222 is started, and the motor drives the rotating shaft 223 to rotate. At this time, the pulley 224 on the rotating shaft is linked with the pulley 224 on the outer wall of the rotating rod 115 through the belt 225, thereby driving the rotating rod 115 and the arc-shaped groove turntable on it. Rotating synchronously with the rotating shaft 223, the arc-shaped groove turntable 212 rotates. Because the arc-shaped groove turntable 212 slides against the actuating rods 215 on the multiple sliders 214, the turntable 212 can move the multiple sliders 214 via the actuating rods 215 during rotation. This causes the sliding rod 217 and its clamp 218 to converge towards the center, thus fixing the welded part. This design allows for adaptive clamping of workpieces of different sizes, effectively avoiding workpiece wobbling and displacement caused by unstable clamping, and significantly improving the stability and accuracy of the welding process.

[0030] The movable part 3 includes a movable component 31, which is mounted on the support plate 111 to enable the device to move; and a fixed component 32, which is mounted on the movable component 31 to limit the movement of the movable component 31. The fixed component 32 allows for flexible adjustment of the leg angles of the movable component 31, thereby adjusting the height of the device. The movable component 31 includes two fixed frames 311 fixedly connected to the bottom of the support plate 111. Each fixed frame 311 has two legs 312 hinged to it. A caster wheel 313 is rotatably connected to one end of each leg 312 away from the fixed frame 311. A connecting rod 3 is hinged to each leg 312. 14. Several connecting rods 314 are hinged to a connecting plate 315 at the end away from the support leg 312; wherein, when the multiple support legs 312 rotate relative to the two fixed frames 311, the connecting rods 314 on the support leg 312 will cooperate with the connecting plate 315, so that the connecting plate 315 can drive the multiple support legs 312 to move synchronously through the connecting transmission of the connecting rods 314, which facilitates the synchronous adjustment of the support legs. The fixing component 32 includes a screw 321 fixedly connected to the bottom of the support plate 111. The screw 321 passes through the connecting plate 315 and is slidably connected to the connecting plate 315. A manual knob 322 is threaded on the outer wall of the screw 321, and a spring 32 is wound on the outer wall of the screw 321. 3. One end of the spring 323 is fixedly connected to the support plate 111, and the other end of the spring 323 is fixedly connected to the connecting plate 315. Rotating the manual knob 322 on the outer wall of the screw 321 allows the connecting plate 315 to move under the push of the spring 323. When the multiple support legs 312 connected to the connecting plate 315 sway, the spring 323, the connecting plate 315, and the screw 321 cooperate to reduce swaying. By providing the moving part 3, when it is necessary to move the clamps on the device, they can be easily pushed by the multiple universal wheels 313 on the support legs 312, achieving flexible movement and effectively improving ease of use. If it is necessary to adjust the height of the device, simply rotate the manual knob 322 on the outer wall of the screw 321. The rotary knob 322, under the elastic force of the spring 323, will cause the connecting plate 315 to move downward. Since the connecting plate 315 is hinged to multiple connecting rods 314, and the other end of the connecting rods 314 is hinged to the rotatable support leg 312 of the fixed frame 311, as the connecting plate 315 moves, the support leg 312 will drive the caster wheel 313 to complete the height adjustment synchronously through the transmission of the connecting rods 314. In addition, the connecting plate 315 can slide on the screw 321 and be pushed by the spring 323. When the support leg 312 shakes due to uneven ground or external impact, the spring 323 can absorb the impact force through elastic deformation, effectively reducing the shaking amplitude, thereby ensuring the smooth operation of the device.

[0031] One specific application of this embodiment is a motor speed controller: a device used to adjust the speed of a motor. It can change the running speed of the motor according to different needs to meet the working requirements of various equipment. For example, the HW-A-1020 and HW-A-1040 DC motor speed controllers are based on the pulse width modulation (PWM) principle. By changing the duty cycle of the output square wave, the average current power on the load changes from 0 to 100%, thereby changing the motor speed. Models: SPC1000E60W, SPC1000E90W, etc. It can be combined with a speed-regulating motor to achieve a wide range of stepless speed regulation and has rich functions such as slow acceleration and slow deceleration.

[0032] In use, the workpiece to be welded can be placed on the worktable 211. Then, the speed controller 112 controls the motor 222 to drive the rotating shaft 223 to rotate. At this time, the pulley 224 on the rotating shaft is linked with the pulley 224 on the outer wall of the rotating rod 115 through the belt 225, thereby driving the rotating rod 115 and the arc-shaped groove turntable 212 on it to rotate synchronously with the rotating shaft 223. When the arc-shaped groove turntable 212 rotates, since the arc-shaped groove turntable 212 slides against the actuating rods 215 on the multiple sliders 214, the arc-shaped groove turntable 212 can drive the multiple sliders 214 to move through the actuating rods 215 during the rotation. This causes the sliding rod 217 and its clamp 218 to converge towards the center, completing the fixation of the welded part. Through this setting, adaptive clamping of workpieces of different sizes can be achieved, effectively avoiding workpiece shaking and displacement caused by unstable clamping, and significantly improving the stability and welding accuracy of the welding process. When the clamps on the device need to be moved, they can be easily pushed by the multiple casters 313 on the support leg 312, achieving flexible movement and effectively improving ease of use. If the height of the device needs to be adjusted, simply turn the manual knob 322 on the outer wall of the screw 321. Under the elastic force of the spring 323, the connecting plate 315 will move downward. Since the connecting plate 315 is hinged to multiple connecting rods 314, and the other end of the connecting rods 314 is hinged to the rotatable support leg 312 of the fixed frame 311, as the connecting plate 315 moves, the support leg 312 will drive the casters 313 to complete the height adjustment synchronously through the transmission of the connecting rods 314. In addition, the connecting plate 315 can slide on the screw 321 and be pushed by the spring 323. When the support leg 312 shakes due to uneven ground or external impact, the spring 323 can absorb the impact force through elastic deformation, effectively reducing the shaking amplitude, thereby ensuring the smooth operation of the device.
