Tool and method used for rapid self-inspection of installation size of forklift frame counterweight

Abstract

The invention relates to a tool and method used for rapid self-inspection of the installation size of a forklift frame counterweight. The tool includes a first fixed plate, first positioning pins positioned with left and right counterweight mounting holes of a frame respectively are arranged on the first fixed plate, a side plate surface of the first fixed plate is provided with a first positioning circular plate attached to a straight plate of the frame, the side plate surface is also provided with left and right positioning pins that abut against left and right counterweight suspension plate end faces of the frame and left and right pins attached to inner walls of left and right outer wall plates of the frame, the other side plate surface of the first fixed plate is provided with a second fixed plate parallel to the first fixed plate, a second positioning pin positioned with a positioning hole on a vertical plate of the frame is arranged on the second fixed plate, and a second positioning circular plate attached to the vertical plate of the frame is arranged on a plate surface of the second fixed plate. According to the abovementioned technical scheme, one-time overall detection is performed on the frame through simulation of the condition of attachment between a counterweight and each fitting surface of the frame, and correction is performed according to a result, and work efficiency is improved.

Description

technical field [0001] The invention relates to the field of forklifts, in particular to a quick self-inspection tool and a self-inspection method for the installation size of the forklift frame counterweight. Background technique [0002] When the frame of a forklift is paired with the counterweight, the counterweight matches the straight plate, vertical plate, counterweight hanging plate and the left and right outer wall plates on the frame. During the welding process of the frame, the above parts have welding deformation, and the relative size will change. There is a change, resulting in a gap or interference between the frame and the counterweight during installation, which cannot be installed. How to detect the relative dimensions of several key parts of the vehicle frame and the counterweight before the installation of the vehicle frame and the counterweight becomes the key. At present, the main detection method is to use the combination of steel tape and square for i...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: 1) The method of combining the steel tape and the square cannot intuitively reflect the deformation of the frame; 2) Two people are required to cooperate and multi-point inspection is required, and the inspection cannot be completed at one time, which is time-consuming and laborious; 3) Due to the The single-point inspection cannot reflect the relative size of multiple parts on the frame. It may appear that the relative positions of two parts are qualified, but after the frame and counterweight are installed, the counterweight is inclined to the frame, there is a gap, or it interferes with the counterweight. Re-calibration is required; 4) Since the inspection is carried out by combining a steel tape measure with a square square, there may be errors caused by human factors or the accuracy of the tape measure, and the detection is unreliable
