[0041] The embodiment of the present application discloses a welding auxiliary device for a box door lock. Figure 1 、 2The door lock includes a lock rod 6, a lock head 7 and a lock seat 5. The lock head 7 is connected to both ends of the lock rod 6 through a connecting rod, and the lock seat 5 is for the lock head 7 to rotate and fit into the lock seat to achieve fixation.

[0042] Reference Figure 2 、 3 The welding auxiliary device includes a carrier 1, two sets of locking assemblies 2, a movable seat 4, and a guide assembly 3. The movable seat 4 is movably mounted on the carrier 1. The locking assemblies 2 are located at both ends of the locking rod 6 and are used to secure the locking rod 6, the locking head 7, and the locking seat 5. One set of locking assemblies 2 is fixedly mounted on the movable seat 4, while the other set of locking assemblies 2 is fixed to the carrier 1. The guide assembly 3 cooperates with the movable seat 4 to enable the locking assemblies 2 on the movable seat 4 to move along the axis of the locking rod 6, thereby accommodating welding of locking rods 6 of different lengths.

[0043] Reference Figure 2 、 3 The locking assembly 2 includes a clamping seat 21 and two clamps 22 arranged in sequence. The clamping seat 21 is fixed to the carrier 1 or the movable seat 4 by bolts, and the lock seat 5 is fixed to the clamping seat 21 by bolts. The two clamps 22 are used to fix the locking rod 6 and the lock head 7 respectively, so that the locking rod 6 and the lock head 7 can be plugged in and matched coaxially, which is convenient for welding.

[0044] Specifically, the clamp 22 includes a fixed seat 221 and a movable clamping arm 222. The fixed seat 221 is fixed to the carrier 1 or the movable seat 4 by bolts. A mounting opening 2211 is provided on the fixed seat 221. The mounting opening 2211 is in an arc-shaped structure. The movable clamping arm 222 is fixed to the movable seat 4. The movable clamping arm 222 can be an existing elbow clamp, or a clamp or the like that can press the lock against the mounting opening 2211. In this embodiment, the elbow clamp is used as an example for explanation. When in use, the connecting rod of the lock head 7 is placed into the mounting opening 2211 of one of the clamps 22, and the lock head 7 is limited in position with the lock seat 5. Then, the connecting rod of the lock head 7 is fixed to the mounting opening 2211 by the movable clamping arm 222. Then, after the lock rod 6 is plugged into the connecting rod of the lock head 7, it is also locked and fixed by the movable clamping arm 222, and then the two are welded.

[0045] Reference Figure 4 、 5 The guide assembly 3 includes a guide rod 31 and a guide seat 32. The guide rod 31 is parallel to the installed locking rod 6, and the guide seat 32 is slidably connected to the guide rod 31. One end of the guide seat 32 is fixedly connected to the movable seat 4, allowing the guide seat 32 to move along the length of the guide rod 31. In this embodiment, there are two guide rods 31, which are symmetrically arranged. Each guide rod 31 is slidably connected to two guide seats 32 fixedly connected to the movable seat 4, which improves the stability of the movable seat 4 during sliding.

A fixing bolt 311 is threadedly connected to the end of the guide rod 31. A gasket 312 is mounted on the fixing bolt 311. The gasket 312 is circular and has a diameter larger than the diameter of the mounting hole 331. The fixing bolts 311 and gasket 312 secure the two ends of the guide rod 31.

[0047] Reference Figure 3 To secure the movable seat 4 in the desired position, a positioning member 41 is provided on the movable seat 4. Specifically, the positioning member 41 comprises a positioning bolt that is threadedly connected to the movable seat 4. After adjusting the position of the movable seat 4, the positioning bolt can be rotated to tighten it against the carrier 1, preventing the movable seat 4 from moving during the welding process.

[0048] The number of positioning bolts can be selected according to actual conditions. In this embodiment, four are used as an example. In other embodiments, the positioning member 41 can also be fixed by an eccentric pressure wheel, a spring latch, etc., or even by installing the positioning bolts on the guide seat 32 to fix the guide seat 32 to prevent the movable seat 4 from slipping.

[0049] Reference Figure 2 、 3 A measuring ruler 11 extending in the sliding direction of the movable seat 4 is fixed to the carrier 1 via a pin, and a scale marker 8 is fixed to the movable seat 4 to point to the scale lines of the measuring ruler 11. This improvement allows the operator to more accurately adjust and control the position of the movable seat 4 and accurately understand the overall length of the unlocking tool, thereby improving the accuracy and quality of welding.

[0050] Specifically, refer to Figure 5 The scale identification block 8 includes a connecting block 81 and an indicator block 82 fixedly connected to the connecting block 81. The connecting block 81 is detachably connected to the movable seat 4 by bolts and is also positioned on the movable seat 4 by a pin. This structural design makes the installation and removal of the scale identification block 8 quick and easy, and facilitates maintenance and replacement.
