Description

Movable clamping positioner

Technical Field

The utility model relates to the technical field of automobile manufacturing, in particular to a movable clamping positioner.

Background

Skis are used very widely in the automotive industry, mainly for the transportation of body-in-white between and among various lines, such as the transportation of body-in-white from a main line to repair lines, or the transportation of body-in-white from a body shop to a paint shop, etc. Because skis in different wire bodies or different workshops are different, the changeover of the white body in different wire bodies can be related, and in order to ensure that the white body after the changeover still can accurately enter the locating pin of the skis in the next procedure, the accuracy of the stop position of the skis (namely the white body) on the changeover point rolling machine must be ensured.

In the prior art, a fixed clamping positioner is generally used, as shown in fig. 6: the fixed clamping positioner 7 is arranged on the roller machine, and after the sledge 8 advances to the position at the switching point, the clamping positioner 7 finely positions the position of the sledge 8 in a pneumatic clamping mode by using the positioning cross beam 81 of the sledge 8 so as to meet the precision requirement of the switching of the white car body. However, the existing fixed clamping positioner has the following problems:

The fixed clamping positioner is fixed in position, namely, one fixed clamping positioner can only meet one stop position of the sledge, and the stop positions of white bodywork (namely, sledge) of different vehicle types along the moving direction of the sledge at the transfer point are different, so that the fixed clamping positioner cannot meet flexible compatibility requirements of different stop positions of different vehicle types under normal conditions. At this time, only a plurality of stationary clamp positioners can be installed in order to meet the multiple stop position requirements of the transfer point ski. However, if more vehicle types (for example, more than 5 vehicle types) are encountered, the space of the on-site roller is limited, and the space is insufficient for installing too many fixed clamping locators, so that flexible compatible work cannot be realized.

Accordingly, there is a need to provide an improved solution to the above-mentioned deficiencies of the prior art.
