Description

Technical Field

[0001] This utility model relates to a clamp, specifically a workpiece fixing clamp for welding with multi-angle adjustment, belonging to the field of machining technology. Background Technology

[0002] Machining encompasses a variety of manufacturing processes, such as welding, which uses heat or pressure to join metals. In welding, it is crucial to securely clamp the workpiece to ensure precise positioning of components, prevent misalignment caused by thermal deformation, avoid deviations in the welding position, guarantee the quality and strength of the weld, and minimize operational safety hazards.

[0003] A search revealed a Chinese patent with publication number CN215588482U that discloses a multi-angle adjustable fixture for machining, including a base. A side plate is fixedly connected to the upper end face of the base. A through hole is opened on one side surface of the side plate, and the through hole extends to the other side surface of the side plate. A fixed cylinder is rotatably connected to the inside of the through hole through a bearing.

[0004] While the above solution can adjust the angle, there is still room for optimization in practical applications. The current device requires loosening two locking bolts simultaneously to rotate the angle, and this operation only supports single-dimensional adjustment. At the same time, the fixed cylinder may sag due to gravity after the locking bolts are loosened, resulting in low flexibility and stability. To address these issues, we provide a multi-angle adjustable workpiece clamp for welding. Utility Model Content

[0025] This utility model provides a workpiece fixing fixture with multi-angle adjustment for welding.

[0026] Please see Figure 1 The device includes a device box 1, which integrates a power control box. The power control box is electrically connected to the municipal power supply via wires, thereby ensuring the normal power supply to the electrical equipment in this application.

[0027] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The device box 1 is equipped with an adjustment mechanism 2. The adjustment mechanism 2 includes a limit adjustment tube 201. The inner wall of the limit adjustment tube 201 is rotatably connected to a connecting rod 202. By driving the limit adjustment tube 201 to rotate, the connecting rod 202 can be driven to rotate synchronously.

[0028] The connecting rod 202 is fixedly connected to both ends of the linkage rod 203. The end of the linkage rod 203 away from the connecting rod 202 is slidably connected to the adjusting ring 204. The outer surface of the connecting rod 202 is fixedly connected to the support plate 205. By driving the adjusting ring 204 to move vertically and in combination with the synergistic effect of the linkage rod 203, the connecting rod 202 can be driven to rotate simultaneously within the limit adjustment tube 201.

[0029] An electric actuator 206 is fixedly connected to the inner wall of the device box 1. The telescopic end of the electric actuator 206 is fixedly connected to the adjusting ring 204. A drive motor 207 is fixedly connected to the inner wall of the device box 1. The output end of the drive motor 207 is fixedly connected to the limit adjustment tube 201. Control buttons for the electric actuator 206 and the drive motor 207 are integrated on the outer surface of the device box 1. The electric actuator 206 and the drive motor 207 can be opened and closed by the control buttons. A limit slide 208 is fixedly connected to the outer surface of the adjusting ring 204. The outer surface of the limit slide 208 is slidably connected to the device box 1. The limit slide 208 effectively limits the adjusting ring 204, making the adjusting ring 204 more stable during vertical movement.

[0030] Please refer to it again. Figure 1 and Figure 4 A clamping mechanism 3 is provided above the device box 1. The clamping mechanism 3 includes a support platform 301. The bottom surface of the support platform 301 is fixedly connected to the support plate 205. By driving the support plate 205 to make multi-dimensional adjustments, the support platform 301 can be driven to move synchronously.

[0031] The top surface of the support platform 301 is slidably connected to an active plate 302, and the bottom surface of the active plate 302 is fixedly connected to a limiting plate 303. The outer surface of the limiting plate 303 is slidably connected to the support platform 301. By driving the active plate 302 to move, the limiting plate 303 can be driven to move synchronously. The active plates 302 on both sides of the support platform 301 are installed in staggered layers in the inner wall of the support platform 301, which effectively avoids affecting the clamping of the workpiece.

[0032] The top surface of the active plate 302 is fixedly connected to a connecting shaft 304, and the outer surface of the connecting shaft 304 is rotatably connected to a clamping plate 305. Through the setting of the connecting shaft 304, the clamping plate 305 is effectively supported and limited, so that when adjusting the included angle between the two clamping plates 305, the two can only rotate around the connecting shaft 304 as the axis.

[0033] A fixed insert rod 306 is slidably connected to the inner wall of the clamping plate 305. A support spring 307 is sleeved on the outer surface of the fixed insert rod 306. The two ends of the support spring 307 are fixedly connected to the clamping plate 305 and the fixed insert rod 306 respectively. A baffle is fixedly installed on the outer surface of the fixed insert rod 306. By setting the baffle, the support spring 307 can be squeezed and deformed when the fixed insert rod 306 is pulled upward. Multiple fixed insertion holes are arrayed on the top surface of the limiting plate 303 with the connecting shaft 304 as the center. By setting the fixed insertion holes, the two clamping plates 305 can be limited.

[0034] An electric actuator 208 is fixedly connected to the outer surface of the support platform 301. The telescopic end of the electric actuator 208 is fixedly connected to the active plate 302. By activating the electric actuator 208, the active plate 302 can be effectively pushed to slide on the top surface of the support platform 301. The electric actuator 206, drive motor 207 and electric actuator 308 in this application are all common electrical devices in the prior art. This application will not elaborate on their models and internal structures. They can also be replaced by other power sources.

[0035] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0036] Working principle: First, the fixing rod 306 is inserted into the fixing hole on the top surface of the limiting plate 303, so that the two clamping plates 305 on the surface of the connecting shaft 304 are adjusted to the required angle. Then, the electric actuator 208 is activated to push the active plate 302. The movement of the active plate 302 drives the limiting plate 303 and the clamping plates 305 to move synchronously, effectively clamping and fixing the workpiece. Second, the synergistic action of the electric actuator 206 and the limiting slide bar 208 drives the adjusting ring 204 to move vertically within the device box 1. The vertical movement of the adjusting ring 204 pulls the linkage rod 203 to rotate around the connecting rod 202 as the axis. The rotation of the connecting rod 202 drives the support plate 20 5. Rotation: The rotation of the support plate 205 causes the workpiece on the top surface of the bearing platform 301 to rotate, effectively adjusting the tilt angle of the workpiece. By starting the drive motor 207, the limit adjustment tube 201 is driven to rotate, which in turn drives the connecting rod 202 to rotate. The rotation of the connecting rod 202 drives the support plate 205 to rotate, which in turn drives the workpiece on the top surface of the bearing platform 301 to rotate, effectively adjusting the direction of the workpiece. This allows the device to flexibly adjust the angle of the workpiece in multiple dimensions, significantly improving the welding efficiency of the workpiece while solving the problem of low stability in the angle adjustment process of existing devices, making the device more practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
