Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automobile pillar traction tool used when repairing automobile body parts, particularly when pulling center pillars and windshield pillars with a chain.

[Prior Art and Problems] Repairs to body parts of automobiles that have been deformed due to collisions are usually carried out by clamping the repaired area with clamps, and then mooring and pulling a chain to the clamps. However, when trying to straighten a bent center pillar to its original state, for example, the cross section of the pillar is frame-shaped, so it is impossible to clamp it. ), the only way to avoid damaging the surface of the pillar was to wrap a chain around it and pull it. Therefore, it was difficult to correct the pillars and the work efficiency was low.

[Purpose and structure of the invention] The invention aims to efficiently perform the straightening work of automobile pillars. To achieve this purpose, the invention provides a pair of lock plates on both sides of the opening of the shaped frame. The present invention provides a pillar traction tool which is pivotally mounted and has chain mooring holes at opposing positions of each lock plate.

[Operation] Both lock plates are opened and a pillar is inserted into the frame, then both lock plates are closed and a chain is moored in the chain mooring hole. Then, by pulling this chain, the pillar is straightened in the pulling direction.

[Embodiment] Reference numeral 1 denotes a shaped frame body, 2, 2 denotes a pair of lock plates bent in a substantially L-shape, and each of the lock plates 2, 2 is arranged opposite to the frame body 1 with its bent side facing inward. They are pivotably mounted 3 on both edges of the opening, respectively. Chain mooring holes 4, 4 are provided at opposing positions on the opposing surfaces of the respective lock plates 2, 2, respectively.

As shown in FIG. 2, the pillar traction tool constructed in this way is constructed by opening both the lock plates 2, 2, inserting the pillar 5 into the frame 1 from the opening side, and then inserting the pillar 5 into the frame 1 from the opening side. Close. As shown in FIG. 3, a chain 6 is moored between both chain mooring holes 4, 4, and by pulling this chain 6, the pillar 5 is straightened in the direction of the tension.

Although not shown, if it is desired to correct a large diameter portion near the lower end of the pillar 5, a large pillar traction tool is used.

[Effect of the invention] Since the pillar can be straightened by a simple operation of inserting the pillar into the frame and pulling the chain passed through the chain mooring hole, the working efficiency of pillar straightening is greatly improved. Furthermore, since the pillar is not corrected by clamping it or wrapping a chain around it, there is no risk of scratching or denting the pillar.
