Detailed Description

Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be oriented 90 degrees or at other orientations and the spatially relative descriptors used herein interpreted accordingly.

The following detailed description of the utility model refers to the accompanying drawings and preferred embodiments. As shown in FIG. 1, a U-shaped plate positioning mechanism comprises

A fixing portion: a base mechanism;

and a vehicle body positioning part: a plate positioning mechanism;

positioning part: a turnover mechanism;

the fixing portion is mainly mounted on the substrate, ensuring the positional accuracy of the entire jig unit. The fixing part is connected with the vehicle body positioning part, so that the position accuracy of the clamp unit and the vehicle body is ensured. The plate positioning part is connected with the vehicle body positioning part, so that the precision between the plate positioning part and the vehicle body is ensured, and the position precision of the U-shaped plate is ensured.

Specifically, the fixed part: a base mechanism 101;

and a vehicle body positioning part: plate positioning mechanism part: the locking handle 201, the mounting piece 202, the limiting block 203, the positioning connecting plate (204), the limiting pin (205), the connecting piece (206) and the positioning surface (207);

positioning part: turnover mechanism part: a reversing cylinder 301 and a cylinder mounting plate 302;

the fixing portion base 101 is mounted on the base plate in a two-pin four-screw manner, and the position accuracy of the whole clamp is ensured.

The positioning part is connected with the fixing part, so that the position accuracy of the clamp unit and the vehicle body is ensured. The overturning cylinder 301 is an outsourcing standard product and comprises a cylinder body and a clamping arm, and the overturning cylinder 301 is connected with the base 101 in a two-pin four-screw mounting mode; the cylinder mounting plate 302 is connected and mounted with the overturning cylinder 301 through two pins and two screws.

And a vehicle body positioning part: plate positioning mechanism part and positioning part: the turnover mechanism is connected with the plate, so that the plate is ensured to be stable in state in the welding process. The mounting piece 202 is connected with the cylinder mounting plate 302 in a two-pin two-screw mode, and the locking handle 201 is connected with the mounting piece 202 in a six-screw mode; the limiting block 203 is connected with the mounting piece 202 in a two-screw mode; the handle 201 with the lock is connected with the positioning connecting plate (204) and the connecting piece (206) in a two-screw mode; the limiting pin (205) moves in the middle of the limiting block 203; the positioning surface (207) is connected with the positioning connecting plate (204) in a two-pin two-screw mode, and meanwhile the positioning precision of the positioning surface is guaranteed.

The method comprises the following steps of specifically operating, manually feeding a plate under the closed state of a cylinder, ensuring that the plate is unique in state by a plate positioning part, manually pushing a handle to the inside of a U-shaped plate, and providing positioning for the inside of the plate to ensure that the state of the plate is unchanged in the welding process, and finishing welding; the worker manually pushes the handle to the original position, and the turnover mechanism is opened.
