Technical Field

[0001] The utility model relates to the technical field of lock rods, in particular to an anti-slip welding fixture for container lock rods. Background Art

[0002] The locking rod comprises a locking rod tube, a plurality of locking rod fixing seats are sleeved on the middle part of the locking rod tube, locking heads are arranged at both ends of the locking rod tube, and a handle is also arranged on the locking rod tube.

[0003] During the welding production process of the lock rod, the two ends of the lock rod are often clamped by a clamp for welding. The clamping directions of the clamps at both ends are often consistent, which makes the product prone to skewing during the welding process, resulting in poor product welding consistency and low product welding yield, which in turn affects the production progress. As a result, after the lock rod is assembled in the later stage, the door may rotate jammed and not smoothly when opened. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide an anti-slip welding fixture for a container lock rod.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A container lock rod anti-skid welding fixture comprises a welding platform, wherein slide plates are symmetrically arranged on the top of the welding platform, and at least one slide plate is slidably connected to the welding platform through a second driving mechanism, and clamping plates are symmetrically arranged on the facing surfaces of the two slide plates, and the clamping directions of the clamping plates on the two slide plates are perpendicular to each other. After the lock rod is clamped by two groups of slide plates with perpendicular clamping directions, the two slide plates are driven by the second driving mechanism to respectively contact the two ends of the lock rod.

[0007] Preferably, the clamping plate is configured as a long strip, and the length of the clamping plate is not less than three fifths of the length of the skateboard.

[0010] Preferably, the driving member is a driving motor or a driving turntable.

A threaded rod is provided at the output end of the driving motor, a threaded block is threaded on the threaded rod, a connecting rod slidably connected to the welding table is fixed on the top of the threaded block, and the connecting rod is fixedly connected to the slide plate.

[0012] Preferably, when only one of the slide plates is slidably connected to the welding table, the threaded rod is configured as a one-way threaded rod, and a threaded block is threadedly arranged on the threaded rod.

[0013] Preferably, when the slide plates are all slidably connected to the welding table, the threaded rod is configured as a bidirectional threaded rod, and threaded blocks are symmetrically arranged on the threaded rod.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model first clamps the locking rod by two sets of slide plates with perpendicular clamping directions to ensure that the two ends of the locking rod are concentric and at the same horizontal height, and then drives the two slide plates to respectively contact the two ends of the locking rod by the second driving mechanism to ensure that the three axes of the locking rod are limited during the welding process, thereby preventing the locking rod from sliding during the welding process;

[0023] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0024] like Figure 1 As shown in the figure, as a container lock rod anti-slip welding fixture of the utility model, it includes a welding platform 1, a driving motor 51 is arranged on one side of the welding platform 1, and a threaded rod 52 is arranged on the output end of the driving motor 51. The threaded rod 52 can be a bidirectional threaded rod or a unidirectional threaded rod. Figure 2 As shown, when the threaded rod 52 is a bidirectional threaded rod, the threaded rod 52 is symmetrically threaded with thread blocks 53, and the two thread blocks 53 are respectively located on different threads, such as Figure 3 As shown, when the threaded rod 52 is a one-way threaded rod, a threaded block 53 is threadedly arranged on the threaded rod 52, and a connecting rod 54 is fixed on the top of the threaded block 53. The connecting rod 54 passes through the welding platform 1 and is slidably connected to the welding platform 1. The end of the connecting rod 54 is fixedly connected to the slide plate 2, and the two slide plates 2 are symmetrically arranged on the top of the welding platform 1.

[0025] The driving motor 51 drives the threaded rod 52 to rotate, thereby driving the threaded block 53 to move on the threaded rod 52. The movement of the threaded block 53 drives the slide plate 2 to move, thereby changing the distance between the two slide plates 2. Then, the driving mechanism 2 5 composed of the driving motor 51, the threaded rod 52, the threaded block 53 and the connecting rod 54 is used to clamp the two ends of the locking rod and limit the locking rod on the X-axis. The unidirectional threaded rod 52 can reduce the driving power, which is beneficial to prolonging the service life of the driving motor 51. The bidirectional threaded rod 52 can make the two threaded blocks 53 move relative to each other, thereby ensuring that the clamped locking rod is always located in the middle of the welding table 1, which is beneficial to supporting the welding table 1.

[0026] like Figure 1 As shown, the two skateboards 2 are symmetrically provided with clamping plates 3 on the facing surfaces, and the clamping directions of the clamping plates 3 on the two skateboards 2 are perpendicular to each other. The locking rod is limited on the Y-axis and the Z-axis by two sets of clamping plates 3 with perpendicular clamping directions, thereby cooperating with the skateboard 2 to limit the locking rod on three axes, thereby preventing the locking rod from sliding during welding.

[0027] The side of the slide plate 2 is provided with a driving member 41, such as Figure 4As shown, a bidirectional screw rod 42 is provided at the output end of the driving member 41, and the bidirectional screw rod 42 passes through the slide plate 2 and is located inside the slide plate 2. Moving blocks 43 are symmetrically provided on the bidirectional screw rod 42, and the moving blocks 43 are fixedly connected to the clamp plate 3. The bidirectional screw rod 42 is driven to rotate by the driving member 41, thereby driving the two moving blocks 43 to move in opposite directions on the bidirectional screw rod 42. The distance between the clamp plates 3 is adjusted by the driving mechanism 1 4 composed of the driving member 41, the bidirectional screw rod 42 and the moving blocks 43, and then the distance between the clamp plate 3 and the slide plate 2 is adjusted by the driving mechanism 1 4 and the driving mechanism 2 5, so that the product is suitable for locking rods of different sizes by adjusting the distance, thereby increasing the application range of the product. The driving member 41 is a driving motor or a driving turntable. Mechanization is achieved by the driving motor, and the cost is reduced by the driving turntable. The appropriate driving method is selected according to the actual situation.

[0028] like Figure 1 As shown, the clamping plate 3 can be configured as a long strip, and the length thereof is not less than three fifths of the length of the slide plate 2. Figure 4 As shown, the splint 3 can also be set to be an outwardly concave arc shape, and the curvature is the same as the curvature of the locking rod. The long strip-shaped splint 3 is suitable for locking rods with flat ends, and the arc-shaped splint 3 is suitable for locking rods with arc-shaped ends, thereby improving the clamping and limiting effect through surface contact. At the same time, splints 3 of various shapes are suitable for more scenarios, increasing the scope of application.

[0029] When in use, the locking rod is placed between the four clamps 3, and the distance between the clamps 3 is adjusted by the driving mechanism 1 4 so that the locking rod is in a horizontal state and the two ends are concentric, and then the distance between the slides 2 is adjusted by the driving mechanism 2 5 so that both ends of the locking rod are in contact with the slides 2, ensuring that the three axes of the locking rod are limited during the welding process, thereby improving stability and preventing the locking rod from sliding during the welding process.

[0030] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
