Problems solved by technology
Most of the existing pullers use a worm gear to drive the pulling rod up. The advantage is that it is easy to control the lifting height, and the pulling rod can automatically lock the position through the thread after it rises, and it will not slide down. However, the pulling rod rises and It is very inconvenient to use the handle for many turns when it is lowered and reset. At the same time, in order to keep the pull-out rod rising vertically, a bar-shaped plane needs to be processed on the pull-out rod for limit position, which increases the difficulty and cost of processing, and the pull When the pull rod is lifted, it still receives a rotating force, and in severe cases, the pull nail will be unscrewed

The invention discloses a welding gun puller which comprises a seat frame, a drawing bracket which is arranged on the seat frame; a drawing rod which is arranged on the drawing support in a lifting mode, wherein a connecting piece is arranged at the end, facing the bottom frame, of the drawing rod, and a welding head is arranged at the end of the connecting piece; a lifting device which is of a lever type structure, wherein the lifting device is arranged on the drawing support and connected with the drawing rod, and the lifting device acts to drive the drawing rod to ascend; a locking piece, wherein one end of the locking piece is hinged to the lifting device or the drawing support, a locking hole is formed in the locking piece, the drawing rod penetrates through the locking hole, the locking piece is obliquely arranged, an included angle is formed between the locking piece and the drawing rod, and the locking hole clamps the drawing rod; and a hooking and pulling device which is detachably arranged on the outer side of the connecting piece in a sleeving mode, and after the hooking and pulling device is detached, the hooking and pulling device is installed between the bottom frame and the locking piece, so that the locking piece is horizontally arranged. The device of the embodiment of the invention is simple in structure and convenient to use, can assist production well, lowers the labor intensity, and lowers the production cost.
Description
technical field [0001] The invention relates to the technical field of automobile sheet metal repair, in particular to a welding torch puller. Background technique [0002] When repairing the fuselage of a car that has been deformed by collision, it is generally necessary to use corresponding tools, and a puller is one of the commonly used tools for repairing the deformed fuselage of a car. The use process of the puller is as follows: When the puller nail is fixed on the concave part of the rice by spot welding, etc., use the puller to hook the puller nail, and pull it up through the lifting device on the puller Pull out the nail to drive the sunken position to lift and recover. Most of the existing pullers use a worm gear to drive the pulling rod up. The advantage is that it is easy to control the lifting height, and after the pulling rod rises, it can automatically lock the position through the thread and will not slide down. However, the pulling rod rises and It is very...
