Description

Technical Field

[0001] This utility model belongs to the field of metal oxy-acetylene welding technology, and particularly relates to a multi-angle welding workbench for oxy-acetylene welding. Background Technology

[0002] Oxy-acetylene welding is a gas welding method that uses the heat generated by the combustion of acetylene and oxygen to weld. The core of oxy-acetylene welding is to achieve a direct connection between materials to form a weld. This process requires the application of heat. When welding metal parts, they usually need to be placed on a welding workbench for welding operations, so a welding workbench is required.

[0003] Currently, existing oxy-acetylene welding workbenches have the following shortcomings: 1. During welding, to ensure the required weld angle and quality, the welding angle needs to be adjusted by rotating the metal parts. For some long tubular weldments, the welding height needs to be adjusted and effective clamping is required for welding. Existing workbenches cannot allow free rotation of the metal parts during welding or adjust the height of long tubular weldments; 2. Due to their light weight, metal parts with welding angle requirements need to be secured regardless of their size during welding. However, existing workbenches cannot secure such parts, making welding difficult. Therefore, a new type of multi-angle oxy-acetylene welding workbench needs to be designed to allow free rotation of the metal parts during welding, adjust the height of long tubular weldments, and secure lightweight metal parts with welding angle requirements. Utility Model Content

[0004] To address the aforementioned shortcomings, this utility model provides an oxy-acetylene welding multi-angle welding workbench, which can effectively solve the problems of metal parts not being able to rotate freely during welding, the inability to adjust the height of long tubular welding parts, and the inability to secure lightweight parts with welding angle requirements, making the welding of such parts difficult.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An oxy-acetylene welding multi-angle welding workbench, the multi-angle welding workbench comprising a vise 1, a small cover plate 2, and a rotary table 3.

[0007] The rotating table 3 includes a bearing 3-1, a limiting bolt 3-2, an upper platform 3-3, and a connecting column 3-4. The connecting column 3-4 is a hollow column for long tubular welded parts to pass through. The column body of the connecting column 3-4 has multiple limiting holes along its length, which cooperate with the limiting bolt 3-2 to fix the height of the long tubular welded parts. Both ends of the connecting column 3-4 are fixedly connected to an annular platform, the size of which is the same as the inner hole of the connecting column 3-4. The upper platform 3-3 has a coaxial circular groove in the middle for inserting and fixing the small cover plate 2. The inner ring of the bearing 3-1 is fixed to the lower side of the upper platform 3-3 on the upper part of the connecting column 3-4, and the outer ring is fixed to the table, so that the rotating table 3 can rotate freely.

[0008] The small cover plate 2 is a circular cover plate, the diameter of which matches the inner diameter of the circular groove on the table surface 3-3 of the rotary table 3. In use, the small cover plate 2 is inserted into the circular groove so that it can rotate synchronously with the rotary table 3. Two guide rails 2-1 are symmetrically arranged on one side of the small cover plate 2 for sliding engagement with the vise 1. The other side is a smooth platform for welding lightweight metal parts with welding angle requirements. Two grooves 2-2 are made opposite to each other at the edge of this side. When the side with guide rails 2-1 is inserted into the circular groove upwards, the grooves 2-2 are used to cooperate with tools to remove the small cover plate 2.

[0009] The vise 1 includes a support frame 1-1, a vise guide rail 1-2, a lead screw 1-5, jaws 1-3, and a clamping handle 1-4. The support frame 1-1 includes a lower base and an upper U-shaped frame. The U-shaped frame opens downwards, with one end hinged to the base to form an opening and closing mechanism. The other end is hinged to the clamping handle 1-4, which hooks onto the base on the same side, locking the U-shaped frame and base in a closed state. A threaded through hole is formed at the center of the top of the U-shaped frame for the lead screw 1-5 to pass through. The upper jaw of the jaws 1-3 is fixed inside the base, and the lower jaw is set inside the U-shaped frame. The two ends of the upper jaw engage with the inner sides of the two arms of the U-shaped frame, allowing the upper jaw to move up and down. The bottom end of the screw 1-5 engages with the top end of the upper jaw. By turning the screw 1-5, the position of the upper jaw is adjusted to clamp the welded part. There are two bench vise guide rails 1-2, which are symmetrically fixed at the bottom of the base of the support frame 1-1 and slide with the two guide rails 2-1 on the small cover plate 2. They are used to adjust the welded part to the optimal welding position.

[0010] The beneficial effects of this utility model are: it enables the workbench to rotate freely 360°, adjusts the height of long tubular metal parts, and adjusts the welding angle of lightweight parts that require welding angles; in addition, the small cover plate is connected to the vise via a guide rail, which increases the portability of the vise.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below.

[0018] This embodiment provides a multi-angle welding workbench for oxy-acetylene welding. The multi-angle welding workbench includes a vise 1, a small cover plate 2, and a rotary table 3. Figure 1 As shown.

[0019] like Figure 2 As shown, the rotating table 3 includes a bearing 3-1, a limiting bolt 3-2, an upper platform 3-3, and a connecting column 3-4. The connecting column 3-4 is a hollow column for long tubular welded parts to pass through. The column body of the connecting column 3-4 has six limiting holes along its length, which cooperate with the limiting bolt 3-2 to fix the height of the long tubular welded parts. Both ends of the connecting column 3-4 are fixedly connected to an annular platform, the inner diameter of which is the same as the inner diameter of the connecting column 3-4. A coaxial circular groove is formed in the middle of the upper platform 3-3 for inserting and fixing a small cover plate 2. The inner ring of the bearing 3-1 is fixed to the lower side of the upper platform 3-3 on the upper part of the connecting column 3-4, and the outer ring is fixed to the table, allowing the rotating table 3 to rotate freely. Figure 3 As shown.

[0020] like Figure 5As shown, the small cover plate 2 is a circular cover plate, the diameter of which matches the inner diameter of the circular groove on the table surface 3-3 of the rotary table 3. In use, the small cover plate 2 is inserted into the circular groove so that it can rotate synchronously with the rotary table 3. Two guide rails 2-1 are symmetrically arranged on one side of the small cover plate 2 for sliding engagement with the vise 1. The other side is a smooth platform for use when welding heavy metal parts with welding angle requirements. Two grooves 2-2 are made opposite to each other at the edge of this side. When the side with guide rails 2-1 is inserted into the circular groove upwards, the grooves 2-2 are used to cooperate with tools to remove the small cover plate 2.

[0021] like Figure 4 As shown, the vise 1 includes a support frame 1-1, a vise guide rail 1-2, a lead screw 1-5, jaws 1-3, and a clamping handle 1-4. The support frame 1-1 includes a lower base and an upper U-shaped frame. The U-shaped frame opens downwards, with one end hinged to the base to form an opening and closing mechanism. The other end is hinged to the clamping handle 1-4, which hooks onto the base on the same side, locking the U-shaped frame and base in a closed state. A threaded through hole is formed at the center of the top of the U-shaped frame for the lead screw 1-5 to pass through. The screw thread fits the upper jaw of the jaw 1-3, which is fixed inside the base and set inside the U-shaped frame. The two ends of the upper jaw fit with the inner sides of the two arms of the U-shaped frame, allowing the upper jaw to move up and down. The bottom end of the screw 1-5 rotates with the top end of the upper jaw. Turning the screw 1-5 adjusts the position of the upper jaw to clamp the welded parts. There are two bench vise guide rails 1-2, which are symmetrically fixed at the bottom of the support frame 1-1 base and slide with the two guide rails 2-1 on the small cover plate 2 to adjust the welded parts to the optimal welding position.

[0022] The above-mentioned method for using the oxy-acetylene welding multi-angle welding workbench includes three application scenarios: metal parts that need to rotate freely, long tubular welding parts, and lightweight metal parts. The steps for each scenario are as follows:

[0023] The welding method for metal parts that need to be freely rotated includes:

[0024] Step 1: Fix the outer ring of bearing 3-1 of the oxy-acetylene welding multi-angle welding workbench to the table, so that the lower surface of the rotary table 3 is a certain distance off the ground, so that the workbench can rotate freely 360°; put the side of the small cover plate 2 with the guide rail 2-1 facing up, and fit the vise guide rail 1-2 into the guide rail 2-1 of the small cover plate 2, and then snap the small cover plate 2 into the circular groove of the upper surface 3-3 of the rotary table 3 to complete the fixation.

[0025] Step 2: Fix the metal part to be welded at jaws 1-3 of vise 1, and adjust the angle of the metal part to achieve the optimal welding angle; adjust the position of vise 1 on the table surface 3-3 of rotary table 3 through guide rail 2-1 so that the position of the metal part is the optimal welding position. During the welding process, the welding angle can be adjusted by controlling the lower table surface of rotary table 3.

[0026] The methods of use when welding long tubular components include:

[0027] Step 1: Fix the outer ring of bearing 3-1 of the oxy-acetylene welding multi-angle welding workbench to the table, so that the lower surface of the rotating table 3 is a certain distance from the ground, so that the workbench can rotate freely 360°; do not install the small cover plate 2, so that the inner hole of the upper surface 3-3 of the rotating table 3 and the inner hole of the connecting column 3-4 are exposed.

[0028] Step 2: Insert the long tubular welding part to be welded into the inner hole of the rotary table 3. After adjusting the height to the required height, fix it through the limiting hole on the connecting column 3-4 and the limiting bolt 3-2. During the welding process, the welding angle can be adjusted by adjusting the lower surface of the rotary table 3.

[0029] The methods for welding lightweight metal parts include:

[0030] Step 1: Fix the outer ring of bearing 3-1 of the oxy-acetylene welding multi-angle welding workbench to the table, so that the lower surface of the workbench is a certain distance from the ground, so that the workbench can rotate freely 360°; insert the smooth platform side of the small cover plate 2 with groove 2-2 facing up into the circular groove of the upper surface 3-3 of the rotary table 3.

[0031] Step 2: Place the lightweight metal part to be welded on the small cover plate 2, adjust the lightweight metal part to achieve the best welding angle, and adjust the welding angle by adjusting the lower surface of the rotary table 3 during the welding process.
