Abstract

The invention discloses a splice welding locating device for a front frame of a loading machine. The splice welding locating device for the front frame of the loading machine comprises a pedestal, and the pedestal is provided with a left outer locating frame, a left inner locating frame, a right inner locating frame and a right outer locating frame. The splice welding locating device for the front frame of the loading machine uses locating shaft and locating surface locating principles, the position precision is guaranteed when splice welding a workpiece, each size is guaranteed through locating, and the measuring tool use is reduced; by means of a pneumatic system, the labor intensity is reduced, the locating is reliable, and the product quality and production efficiency are improved; by means of a measurement reference surface on a fixture, a worker can more conveniently and precisely measure each size of the workpiece. The splice welding locating device for the front frame of the loading machine avoids the displacement and size deviation in the welding process and enables the efficiency to be improved, the cost to be lowered, the quality to be guaranteed and the resource to be saved, and the structure is simple.

Description

technical field [0001] The invention belongs to the field of workpiece welding, and in particular relates to a positioning device for tailor welding of the front frame of a loader. Background technique [0002] The front frame is an important part with complex structure on the loader. The shape of the front frame is a box-like structure, and there are many welding components, and there are many angles and positions of each positioning surface. [0003] The traditional method is to mark and position on the tailor welding platform, and use measuring tools such as steel tape measure, square ruler, height ruler and steel ruler to combine the components that make up the front frame according to the size requirements, and measure the verticality, symmetry, and so on of the workpiece. Surface and hole position and other dimensions, after the measurement meets the requirements, the parts are spot welded into a front frame assembly. [0004] Marking the line on the tailor welding p...
