Description

Technical Field

[0001] This application relates to the technical field of laser welding, and in particular to a welding device for stainless steel gas traps. Background Technology

[0002] During the production process, holes need to be drilled in the kettle body, and fittings, flanges or connectors are welded into the holes for connection with external pipelines.

[0003] Currently, during the welding process, the connector is usually welded onto the workpiece manually. The worker places the connector at the opening and holds it in a supporting position, while using the other hand to hold the welding torch to weld the joint between the connector and the workpiece.

[0004] Regarding the aforementioned technologies, the inventors believe that manual welding involves intense arc light that can burn the skin. Even with a welding helmet, prolonged exposure to this light can still lead to decreased eyesight and harm the health of the workers. Utility Model Content

[0005] In order to automate the welding of air-tight containers and reduce the health hazards of manual welding to workers, this application provides a stainless steel air-tight container welding device.

[0006] The stainless steel gas trap welding equipment provided in this application adopts the following technical solution:

[0007] A stainless steel gas-tight kettle welding device includes a frame, a clamping assembly, and a welding assembly. The clamping assembly includes a drive cylinder, a clamping block, and a mounting base. The mounting base is connected to the frame and has a groove at its upper end. The groove wall is used to fit against the outer wall of the kettle body. The clamping block is slidably connected to the frame and slides vertically. The clamping block is used to clamp the upper end of a connecting piece. The drive cylinder is connected to the frame and drives the clamping block to slide. The welding assembly is slidably connected to the frame and is used to weld the connection between the kettle body and the connecting piece.

[0008] By adopting the above technical solution, the staff will embed the pot body into the groove and the connector into the opening of the pot body. The drive cylinder will drive the clamping block to move down and clamp the upper end of the connector, thereby fixing the connector and the pot body relatively. The welding assembly will weld the connection between the connector and the pot body. This way, the staff does not need to get close to the equipment during the welding process, reducing the impact of the welding arc light generated during welding on the health of the staff.

[0009] Preferably, the clamping assembly further includes a three-jaw chuck and a clamping drive motor. The three-jaw chuck is rotatably connected to the frame, and the rotation axis of the three-jaw chuck is vertical. The mounting base is connected to the upper end of the three-jaw chuck, and the clamping drive motor is connected to the frame. The clamping drive motor is used to drive the three-jaw chuck to rotate.

[0010] By adopting the above technical solution, a three-jaw chuck is set up, and the mounting base is connected to the upper end of the three-jaw chuck. This facilitates the replacement of mounting bases with different sizes and shapes of slots to adapt to different sizes and styles of kettle bodies, thereby improving the applicability of the equipment and reducing production costs. The clamping drive motor drives the three-jaw chuck to rotate, which in turn drives the mounting base to rotate, and then drives the kettle body and connecting parts to rotate, realizing circumferential welding at the connection between the kettle body and the connecting parts. This reduces the movement of the welding components and improves welding efficiency.

[0011] Preferably, the clamping assembly further includes a guide post and a sliding plate, the lower end of the guide post is connected to the frame, the sliding plate is slidably connected to the guide post, the sliding direction of the sliding plate is parallel to the length direction of the guide post, and the upper end of the abutment block is connected to the sliding plate.

[0012] By adopting the above technical solution, the sliding plate slides along the length of the guide post, making the sliding of the sliding plate more accurate, ensuring that the clamping block is pressed against the upper end of the connector, and improving the stability of the connection between the kettle body and the connector.

[0013] Preferably, the clamping block is rotatably connected to the sliding plate, and the rotation axis of the clamping block coincides with the rotation axis of the three-jaw chuck.

[0014] By adopting the above technical solution, the clamping block is rotatably connected to the sliding plate, so that when the three-jaw chuck drives the kettle body and the connecting parts to rotate, the clamping block and the connecting parts are relatively fixed, reducing the possibility of wear on the clamping block and connecting parts components and improving the service life of the equipment.

[0015] Preferably, the lower end of the abutment block is provided with a cone, the axis of the cone coincides with the rotation axis of the abutment block, and the outer wall of the cone is used to abut against the inner wall of the connector.

[0016] By adopting the above technical solution, the axis of the cone coincides with the rotation axis of the clamping block, the outer wall of the cone abuts against the upper end of the inner wall of the connector, and the outer wall of the cone guides the connector, so that the axis of the connector coincides with the axis of the cone, and the axis of the connector coincides with the rotation axis of the three-jaw chuck, which helps to weld the circumferential connection between the connector and the pot body and improves the assembly efficiency.

[0017] Preferably, the clamping assembly further includes a linear bearing, which is slidably connected to a guide post. The guide post is located inside the linear bearing, and the number of linear bearings is the same as the number of guide posts and corresponds one-to-one. The linear bearing is connected to a sliding plate.

[0018] By adopting the above technical solution, the linear bearing and the guide post move in a straight line with minimal frictional resistance, high precision, and fast movement, making the sliding plate slide more smoothly.

[0019] Preferably, there are two clamping components, which are distributed at intervals along the horizontal direction.

[0020] By adopting the above technical solution and setting two clamping components, the kettle body and connector can be assembled on the other clamping component while the welding component is welding the kettle body and connector on one clamping component, thereby improving work efficiency.

[0021] Preferably, it further includes a lateral drive assembly, a longitudinal drive assembly, and a vertical drive assembly. The lateral drive assembly is connected to the frame and is used to drive the welding assembly to slide along the X direction. The longitudinal drive assembly is connected to the frame and is used to drive the welding assembly to slide along the Y direction, where the X direction is perpendicular to the Y direction. The vertical drive assembly is connected to the frame and is used to drive the welding assembly to slide in the vertical direction.

[0022] By adopting the above technical solution, the welding assembly is driven to slide through the horizontal drive assembly, the vertical drive assembly, and the vertical drive assembly, thereby automatically realizing welding and improving the automation level of the equipment.

[0023] Preferably, it further includes an air extraction assembly, which includes an air pump and an air extraction pipe. The air pump is connected to the welding assembly, one end of the air extraction pipe is connected to the air inlet of the air pump, and the other end of the air extraction pipe faces the welding assembly and is close to the clamping assembly.

[0024] By adopting the above technical solution, the air pump will extract the waste gas generated during welding through the extraction pipe, reducing the harm to the health of workers and improving the safety of the equipment.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The worker inserts the kettle body into the groove and the connector into the opening of the kettle body. The drive cylinder drives the clamping block to move down and press against the upper end of the connector, so as to fix the connector and the kettle body relatively. The welding assembly welds the connection between the connector and the kettle body. During the welding process, the worker does not need to get close to the equipment, reducing the impact of the welding arc light generated during welding on the worker's health.

[0027] 2. The clamping block is rotatably connected to the sliding plate, so that when the three-jaw chuck drives the kettle body and the connecting part to rotate, the clamping block and the connecting part are relatively fixed, reducing the possibility of wear on the clamping block and connecting part components and improving the service life of the equipment. The axis of the cone coincides with the rotation axis of the clamping block, and the outer wall of the cone abuts against the upper end of the inner wall of the connecting part. The outer wall of the cone plays a guiding role for the connecting part, realizing that the axis of the connecting part coincides with the axis of the cone, and that the axis of the connecting part coincides with the rotation axis of the three-jaw chuck. This helps to weld the circumferential joint between the connecting part and the kettle body in the future and improves the assembly efficiency.

[0028] 3. The air pump operates to extract the waste gas generated during welding through the extraction pipe, reducing the harm to the health of workers and improving the safety of the equipment. Attached Figure Description
