Description

Technical Field

[0001] The present invention belongs to the technical field of welding positioning devices, and in particular relates to a welding positioning device. Background Art

[0002] Usually, a welding positioning device is required during the welding process to ensure the position accuracy of the workpiece during the welding process and improve the quality and accuracy of the weld. The use of a welding positioning device can simplify the positioning and fixing process of the workpiece, reduce the difficulty and risk of operation, and thus improve production efficiency.

[0003] After searching, Chinese patent announcement number: CN220547819U discloses a welding positioning device, including a welding table, which realizes the support and lifting of the welding workpiece by setting a supporting component. Compared with the traditional structure, the device places the welding workpiece on the surface of the support plate, and can push the connecting rod to move through the extension and retraction of the output end of the cylinder, so that the connecting rod can push the support plate up, and then support the welding workpiece, which is convenient for constraining and adjusting the welding workpiece.

[0004] Considering that it is often necessary to weld two groups of parts at multiple angles during the welding process, the above-mentioned device fixes the clamping plate with bolts. When the angle needs to be adjusted, the staff uses tools to screw the bolts to adjust the angle of the clamping plate, which makes it cumbersome to adjust the angle of the welding clamping device, thereby reducing the efficiency of the welding positioning device when in use. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a welding positioning device, which, according to the multi-angle welding needs of two groups of parts, can achieve multi-angle fixation of the two groups of parts through the setting of a fixed vise and a rotating vise, thereby facilitating subsequent welding.

[0006] The purpose of this disclosure can be achieved through the following technical solutions:

[0007] A welding positioning device, comprising:

[0008] A welding table, wherein two bench clamps are arranged side by side on the welding table, one of which is fixedly connected to the welding table, and the other is rotatably connected to the welding table;

[0009] A handle, wherein the handle is fixedly connected to a rotatable bench vise, a cavity communicating with the outside is provided inside the handle, a connecting rod is arranged in the cavity, a middle portion of the connecting rod is rotatably connected to a side wall of the cavity, an end of the connecting rod away from the bench vise extends to the outside of the cavity, an end of the connecting rod close to the bench vise is rotatably connected to a positioning column, the positioning column vertically penetrates the handle and extends downward, a tension spring is sleeved on the positioning column, an upper end of the tension spring is fixedly connected to a top end of the positioning column, and a lower end of the tension spring is fixedly connected to a bottom wall of the cavity;

[0010] The welding table is provided with a plurality of positioning holes for inserting positioning columns.

[0011] The above technical solution, its principle and technical effect:

[0012] According to the angle required for welding between the two parts, the staff holds the handle and the connecting rod, and the inner end of the connecting rod 5 is tilted to drive the positioning column to move up, so that the positioning column is separated from the positioning hole. At this time, the tension spring is stretched, and the rotating vise is adjusted to the corresponding angle position. The handle and the connecting rod are released, and the positioning column is moved down and inserted into the positioning hole under the tension of the tension spring. At this time, the vise is fixed and cannot be rotated. After the two parts are placed on the corresponding vise and clamped, they can be welded by the welding machine.

[0013] Furthermore, a pin is rotatably connected to the middle portion of the connecting rod, and both ends of the pin are fixedly connected to the side walls of the cavity.

[0014] Furthermore, the connecting rod is a telescopic rod, and the telescopic part is located between the pin shaft and the positioning column.

[0015] Furthermore, a fastening bolt is vertically threadedly connected to the handle near the vise.

[0016] Furthermore, the lower end of the handle is fixedly connected to a limiting block, the welding platform is provided with an arc-shaped limiting groove, and the limiting block is slidably connected in the arc-shaped limiting groove.

[0017] Furthermore, the bench vise includes a base plate, and the two ends of the upper surface of the base plate are respectively fixedly connected with a fixed plate and a fixed clamping plate, a movable clamping plate is arranged between the fixed plate and the fixed clamping plate, a screw rod is threadedly connected on the fixed plate, and the end of the screw rod is rotatably connected to the movable clamping plate.

[0018] Furthermore, two ends of the fixed plate are slidably connected with movable columns, and the ends of the movable columns are fixedly connected to the movable clamping plate.

[0019] Furthermore, the handle is fixedly connected to a bottom plate of the rotating vise.

[0020] Furthermore, the bottom plate of the rotating vise is rotatably connected to the connecting column, and the connecting column is fixedly connected to the welding table.

[0021] Furthermore, the welding platform is provided with an arc-shaped edge on the circumferential side of the arc-shaped limiting groove.

[0022] In a preferred example, the present invention can be further configured as follows:

[0023] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0024] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0025] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0026] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0027] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0028] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0029] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0030] Beneficial effects of the present disclosure:

[0031] 1. In the utility model, the vise is released from the welding table by pressing the connecting rod hinged on the handle, and then the vise is driven to move in an arc along the connecting column by moving the handle. When the angle to be adjusted is reached, the pressing on the connecting rod is released, and the positioning column is inserted into the preset positioning hole to fix the vise. This further makes the process of adjusting the clamping more labor-saving.

[0032] 2. In the utility model, by penetrating the outer wall of the handle and threading the fastening bolt, the mobile bench vise cannot be fixed at more angles during the adjustment process because the positioning column can only be clamped in the preset positioning hole. By rotating the fastening bolt, the handle can be fixed at more angles through the fastening bolt, so that the device can be adjusted to more angles, further improving work efficiency.
