[0001] The utility model relates to the technical field of bottom plate welding, in particular to a bottom plate welding positioning device. Background Technique

[0002] The bottom plate is the bottom support plate of mechanical equipment and some structural components. Common processing methods in the bottom processing process include cutting, drilling, welding, etc. When welding the bottom plate, it is necessary to ensure the stability of the bottom plate to ensure the accuracy of subsequent bottom plate welding. Therefore, during the welding process of the bottom plate, a positioning device is required to clamp and position the bottom, and then weld it after it is stably placed.

[0003] In the traditional bottom plate welding positioning device, during the welding process of the bottom plate, generally, the positioning block is manually operated to move up and down to position the bottom plate. This positioning process has low efficiency and requires manual support. Therefore, we propose a bottom plate welding positioning device to improve the above problems. Content of the Utility Model

[0023] Embodiment 1: Please refer to Figures 1-4 , a bottom - plate welding positioning device, including a support base 1, a base 13 is fixed at the bottom end of the support base 1, a support rod 2 is fixed at one end of the top of the support base 1, a rotating circular plate 8 is hingedly installed at one end of the support rod 2, a cross - plate 5 is fixed at one end of the rotating circular plate 8, a placing plate 4 is fixed at the bottom end of one end of the cross - plate 5, a fixing plate 6 is fixed at the top end of one end of the cross - plate 5, telescopic cylinders 9 are installed inside the fixing plate 6, a pushing block 10 is fixed at the bottom end of the telescopic cylinder 9, limiting blocks 11 are fixed at the bottom ends of the pushing blocks 10, and friction particles 12 are fixed at the bottom ends of the limiting blocks 11. A number of friction particles 12 are provided, and the number of friction particles 12 are evenly distributed at the bottom end of the limiting block 11. The setting of the friction particles 12 makes the friction between the limiting block 11 and the bottom - plate stronger and the positioning effect better. A number of telescopic cylinders 9 are provided, and the number of telescopic cylinders 9 are evenly distributed at one end of the cross - plate 5. The evenly distributed telescopic cylinders 9 position the bottom - plate more stably;

[0024] Specifically, as Figure 1 and Figure 2As shown, the bottom end of the bottom plate is placed above the placement plate 4. The telescopic cylinder 9 is activated to push the push block 10 downward to fit above the bottom plate, and then the bottom plate can be positioned well.

[0025] Embodiment 2: One end of the support rod 2 is fixed with a fixed rod 7, and one end of the fixed rod 7 is fixed with an annular ring 3. A guide block 17 is movably arranged on the outer side wall of the annular ring 3, and one end of the guide block 17 is fixed to one end of the cross plate 5. One end of the rotating circular plate 8 is provided with a rotating shaft 14, one end of the rotating shaft 14 is provided with a mounting seat 15, and one end of the mounting seat 15 is provided with a servo motor 16. The cross section of the guide block 17 is larger than that of the annular ring 3, and a sliding structure is formed between the guide block 17 and the annular ring 3. When the rotating circular plate 8 drives the bottom plate positioned inside the cross plate 5 to rotate, the guide block 17 at one end of the cross plate 5 will rotate on the outer side wall of the annular ring 3 to guide the rotation of the cross plate 5 driving the bottom plate, so that the bottom plate rotates and adjusts smoothly;

[0026] Specifically, as Figure 1 and Figure 4 shown, turn the locking bolt 25 to unlock the adjusting rod 19, then pull the adjusting rod 19 to one side to adjust the distance between the vertical blocks 20 to a suitable spacing. After the bottom plate is positioned by the cross plate 5, hold the turning handle 22 and rotate the screw rod 24 to push the locking block 21 to fit on both sides of the bottom plate for clamping on the basis of its positioning.

[0027] Embodiment 3: Cross bars 18 are fixed on both sides of the cross plate 5. Adjusting rods 19 are movably arranged inside the cross bars 18.

Screw rods 24 are movably arranged inside the vertical blocks 20. Turning handles 22 are fixed on one sides of the screw rods 24. Connecting blocks 23 are fixed on the other sides of the screw rods 24, and locking blocks 21 are fixed on one sides of the connecting blocks 23. The cross section of the adjusting rod 19 is smaller than that of the cross bar 18, and a sliding structure is formed between the adjusting rod 19 and the cross bar 18. There are two groups of locking blocks 21, and the two groups of locking blocks 21 are symmetrically distributed about the central axis of the cross plate 5. The symmetrically distributed locking blocks 21 have a better locking effect on the bottom plate;

[0028] Specifically, as Figure 1 and Figure 2 shown, during use, activate the servo motor 16 to drive the rotating circular plate 8 to rotate. The rotating circular plate 8 drives the cross plate 5 to rotate, and the cross plate 5 drives the bottom plate positioned inside it to turn over, so as to facilitate welding processing on different surfaces of the bottom plate.

[0029] Working principle: When the utility model is in use, turn the locking bolt 25 to unlock the adjusting rod 19, then pull the adjusting rod 19 to one side to adjust the distance between the vertical blocks 20 to a suitable spacing. Fetch the bottom plate and place it between the placing plate 4 and the fixing plate 6, and place the bottom plate against the placing plate 4. Then start the telescopic cylinder 9 to push the limiting block 11 below the pushing block 10 to fit against the upper surface of the bottom plate for positioning. After positioning, hold the turning handle 22 and turn the screw rod 24 to push the locking block 21 to fit against both sides of the bottom plate for clamping on the basis of its positioning. Then welding can be carried out on the upper surface of the bottom plate. During the welding process, the servo motor 16 can also be started to drive the rotating circular plate 8 to rotate. The rotation of the rotating circular plate 8 drives the bottom plate positioned inside the cross plate 5 to rotate, turning the upper surface to the lower side and the lower surface to the upper side for the reverse side of the bottom plate, so as to carry out welding processing on different surfaces of the bottom plate.
