Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to a fixing fixture for a welding platform. Background Technology

[0002] Welding fixtures are used to ensure the size of the weldment, improve assembly accuracy and efficiency, and prevent welding deformation. They mainly use positioning and clamping devices to ensure the stability of the position and posture of the weldment during the welding process.

[0003] Currently, the design of fixed clamps is often designed for welded parts of specific shapes or sizes, such as round or square. However, for welded parts of different specifications or shapes, different clamps may need to be replaced. This design limits the versatility and flexibility of the clamps, making it particularly inconvenient when the welded parts need to be adjusted at multiple angles. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the existing fixing fixture is not convenient for positioning and adjusting weldments of different specifications, and to propose a fixing fixture for a welding platform.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fixing fixture for a welding platform includes a platform body and a mounting shell detachably connected to the platform body. It further includes: at least two sets of guide wheels rotatably connected to the mounting shell; a first clamping plate fixedly connected to the mounting shell, symmetrically arranged along the axis of the guide wheels; a second clamping plate slidably connected to the mounting shell and cooperating with the first clamping plate; a driving component on the mounting shell for driving the second clamping plate closer to the first clamping plate; both the first and second clamping plates have forming grooves for placing weldments; and a liftable pressure plate, with a pressure roller rotatably connected to one end of the pressure plate extending above the guide wheels.

[0007] To achieve position adjustment of the second clamping plate, preferably, the driving component includes: a slide rod slidably connected within the mounting housing, wherein one end of the slide rod extends through the mounting housing to the outside and is fixedly connected to a push plate, and the other end of the slide rod is fixedly connected to a limit rod; a spring sleeved on the limit rod, wherein a positioning plate is fixedly connected to the bottom of the second clamping plate, the positioning plate is slidably connected to the limit rod, and both ends of the spring are fixedly connected to the positioning plate and the mounting housing, respectively.

[0008] To further enable angle adjustment of the weldment, positioning seats are arranged equidistantly in a circle within the forming groove, and ball bearings are provided at the ends of the positioning seats.

[0009] To improve the stability of the welding workpiece clamping, preferably, the top of both the first clamping plate and the second clamping plate are fixedly connected with extension plates, and anti-slip pads are fixedly installed on the opposite sides of the two sets of extension plates.

[0010] In order to drive the guide wheel to rotate, preferably, a motor is fixedly installed in the inner cavity of the mounting housing, and the motor is connected to the guide wheel through a synchronous belt.

[0011] To achieve the lifting and lowering of the pressure roller, preferably, a cylinder is fixedly installed on the mounting shell, and a pressure plate is fixedly connected to the output end of the cylinder. A guide rod is fixedly connected to the mounting shell, and the guide rod passes through the pressure plate.

[0012] Compared with the prior art, the present invention provides a fixing fixture for a welding platform, which has the following advantages:

[0013] 1. The fixing fixture of the welding platform is equipped with a driving component. Pushing the push plate moves the two second clamping plates backward, which opens the fixture. Then, the workpiece is placed between the first clamping plate and the second clamping plate for positioning, thereby improving the efficiency of workpiece assembly and disassembly.

[0014] 2. The fixing fixture of the welding platform is equipped with a motor. The output of the motor drives one of the synchronous pulleys to rotate, which in turn drives the guide pulley to rotate. This allows for angle adjustment of the circular workpiece, thereby improving welding efficiency.

[0015] 3. The fixing fixture of the welding platform, by setting up a cylinder and a pressure roller to cooperate, makes the pressure roller in the pressure roller contact the circular workpiece, which can limit its position and thus improve the stability of its rotational welding.

[0016] The parts not covered in this device are the same as or can be implemented using existing technology. This utility model, through the setting of guide wheels, makes it convenient for workers to adjust the angle of the weldment, thereby improving the welding efficiency of the weldment. Furthermore, by utilizing the design of the forming groove and extension plate, it is possible to position weldments of different shapes, thereby improving the versatility and flexibility of the fixing fixture.

[0025] Example:

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A fixing fixture for a welding platform includes a platform body 1 and a mounting shell 2 detachably connected to the platform body 1. It also includes: at least two sets of guide wheels 6 rotatably connected to the mounting shell 2; a first clamping plate 3 fixedly connected to the mounting shell 2, symmetrically arranged along the axis of the guide wheels 6; a second clamping plate 401 slidably connected to the mounting shell 2 to cooperate with the first clamping plate 3; a driving member 4 on the mounting shell 2 for driving the second clamping plate 401 closer to the first clamping plate 3; forming grooves on opposite sides of the first clamping plate 3 and the second clamping plate 401 for placing weldments; and a liftable pressure plate, with a pressure roller 10 rotatably connected to one end of the pressure plate extending above the guide wheels 6.

[0027] Specifically, the guide wheel 6 allows workers to easily adjust the angle of the weldment, thereby improving the welding efficiency. Furthermore, the design of the forming groove and extension plate enables the positioning of weldments of different shapes, thus improving the versatility and flexibility of the fixing fixture.

[0028] The driving component 4 includes: a slide rod 404 slidably connected inside the mounting shell 2, wherein one end of the slide rod 404 extends through the mounting shell 2 to the outside and is fixedly connected to a push plate 405, and the other end of the slide rod 404 is fixedly connected to a limit rod 406; and a spring 402 sleeved on the limit rod 406, wherein a positioning plate 403 is fixedly connected to the bottom of the second clamping plate 401, the top and bottom of the positioning plate 403 are in contact with the inner wall of the mounting shell 2, the positioning plate 403 is slidably connected to the limit rod 406, and the two ends of the spring 402 are fixedly connected to the positioning plate 403 and the mounting shell 2 respectively.

[0029] Specifically, by setting the driving component 4, the push plate 405 is pushed to move the two second clamping plates 401 backward, thereby opening the clamp. Then, the weldment is placed between the first clamping plate 3 and the second clamping plate 401 to position it, thereby improving the efficiency of weldment assembly and disassembly.

[0030] The molding groove has a number of positioning seats arranged in a circular and equidistant manner, and the ends of the positioning seats are equipped with ball bearings 5.

[0031] Specifically, by setting up a positioning seat and ball bearing 5 to cooperate, the angle of the weldment can be adjusted, thereby improving the welding efficiency of the weldment.

[0032] The top of the first clamping plate 3 and the second clamping plate 401 are both fixedly connected to extension plates, and anti-slip pads 7 are fixedly installed on the opposite sides of the two sets of extension plates. The anti-slip pads 7 are made of rubber.

[0033] Specifically, the rubber anti-slip pad 7 can play an anti-slip role when clamping and positioning sheet metal weldments, thereby improving the stability of clamping sheet metal weldments.

[0034] The motor 8 is fixedly installed in the inner cavity of the mounting housing 2. A synchronous pulley is fixedly installed on one side of both the motor 8 and the guide wheel 6. The two synchronous pulleys are connected by belt drive.

[0035] Specifically, by setting up a motor 8, the output end of the motor 8 drives one of the synchronous pulleys to rotate, which in turn drives the guide wheel 6 to rotate, thereby enabling the angle of the circular weldment to be adjusted, thus improving welding efficiency.

[0036] A cylinder 9 is fixedly mounted on the mounting housing 2, and a pressure plate is fixedly connected to the output end of the cylinder 9. A guide rod is fixedly connected to the mounting housing 2, and the guide rod passes through the pressure plate and is slidably connected to the inner wall of the pressure plate.

[0037] Specifically, by setting up cylinder 9 and pressure plate to cooperate, the height of pressure roller 10 can be adjusted, thereby improving the flexibility of pressure roller 10.

[0038] Working principle: In use, the operator pushes the push plate 405. As the push plate 405 moves, it moves the two sliding rods 404. When the two sliding rods 404 move backward, they move the two positioning plates 403 backward. As the positioning plates 403 move backward, they compress the two springs 402, causing the two second clamping plates 401 to move backward. After the two second clamping plates 401 move to the designated position, the operator places the workpiece between the second clamping plates 401 and the first clamping plate 3. The anti-slip pad 7 can clamp square workpieces, and the forming groove can clamp round workpieces. After the workpiece is placed, the operator releases the push plate 405. At this time, the reaction force of the springs 402 causes the positioning plates 403 to move backward. The position plate 403 moves to reset the second clamping plate 401, thus positioning the workpiece. Subsequently, the operator uses an external control switch to start the cylinder 9. The output end of the cylinder 9 drives the pressure roller 10 to move downward. After the pressure roller 10 contacts the workpiece, welding can begin. During the welding process, the operator uses an external control switch to start the motor 8. The output end of the motor 8 drives one of the synchronous pulleys to rotate. When the synchronous pulley rotates, it drives the belt to drive the transmission. When the belt drives the transmission, it drives the other synchronous pulley to rotate. When the other synchronous pulley rotates, it drives the guide wheel 6 to rotate. When the guide wheel 6 rotates, it can adjust the angle of the circular workpiece at a uniform speed, thereby improving the welding efficiency.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
