Description

[Detailed Description of the Invention] The present invention relates to a two-wheeled vehicle frame welding jig trolley for welding the body frame of a two-wheeled vehicle.

In this type of cart, a plurality of clamp members for clamping the two-wheeled vehicle frame are arranged on the cart, and the cart is conveyed to the side of the welding machine after being clamped by the clamp members, and arc welding is performed by the welding machine. In this case, the two-wheeled vehicle frame is generally grounded at one point on itself or on the jig stand. According to the operation, each welding current drops, and when one operation is performed, the welding current increases.

The purpose of the present invention is to obtain a device free of such inconveniences, and the jig cart 1 on the rail 6 is
A plurality of clamp members 2 for clamping a two-wheeled vehicle frame are disposed in the apparatus, and the jig cart 1 can be freely conveyed to the side of the welding machine 3. A connecting terminal 7 is provided with each insulating layer 4 interposed between it and the trolley 1, and each ground wire 5 is led out to each of the clamp members 2, and the ground wire 5 is provided at the end of the jig trolley 1. It is characterized in that it is attached to and detached from the socket 8 on the outside of the rail 6 via the rail 6.

In the illustrated example, three clamp members 2 are provided on the front and rear sides of each left and right side, and correspondingly, three welding machines 3 are provided on each of the right and left sides on both outer sides.

Each ground wire 5 extends forward to the left in the drawing and connects to each tongue-shaped connection terminal 7 at the front end of the jig table 1, which connects to each terminal socket 8 prepared in advance in front of it. It can be freely inserted into the socket 8 and connected to each ground wire 9 in front of the socket 8.

To explain its operation, consider a case in which arc welding is performed by each welding machine 3 near each part b of a two-wheeled vehicle frame a, and each part b is connected to each clamp member 2 that clamps it. Each ground wire 5
They are connected to earth through the
In this way, good and reliable welding can be achieved at each location b.

In this way, according to the present invention, each clamp member 2 on the jig cart 1 is provided with each insulating layer 4 interposed between it and the cart 1, and each ground wire 5 is led out to each clamp member 2. Therefore, the two-wheeled vehicle frame a clamped to the clamp member 2 is grounded by each ground wire 5, which eliminates the above-mentioned disadvantages of the conventional method when only one point is grounded. Since the wire 5 is connected to and removed from the socket 8 on the outside of the rail 6 via the connection terminal 7 provided at the end of the jig cart 1, the ground wire can be automatically connected and removed when replacing the jig.
This has the effect that the ground wire connection work can be carried out smoothly.
