Special tool for supporting left and right handrails of vehicle middle plate

Abstract

The invention discloses a special tool for supporting left and right handrails of a vehicle middle plate. The special tool comprises a supporting mechanism and a pressing mechanism. The supporting mechanism comprises a bridge passing plate, two first air cylinders and two second air cylinders are symmetrically arranged on the bottom side of the bridge passing plate, push rods of the two second aircylinders penetrate through the upper surface of the bridge passing plate, first supporting blocks and second supporting blocks are arranged on the push rods of the two second air cylinders, first adapter rods are arranged on the push rods of the two first air cylinders, spring pins are arranged on the two first adapter rods, and the left ends of the two spring pins abut against the right ends ofthe first supporting blocks and the right ends of the second supporting blocks respectively. The pressing mechanism comprises a third air cylinder, a second adapter rod is arranged on a push rod of the third air cylinder, and a pressing block is arranged on the side face of the second adapter rod. According to the special tool for supporting the left and right handrails of the vehicle middle plate, the relative position precision of holes is guaranteed, the accumulated tolerance of workpieces is better controlled, the size precision is improved, the defects of the workpieces are reduced, andthe working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of advanced processing and manufacturing, in particular to a special tool for supporting the left and right armrests of the middle panel of a vehicle. Background technique [0002] The left and right armrest support is an important component of the vehicle. It has high requirements for some shape and position tolerances. When the existing technology is processed: it is processed in multiple processes. Multi-process processing can improve efficiency from an objective point of view, and the special tooling for the left and right armrest supports is An indispensable part, the special tooling for left and right armrest support also has the following disadvantages: 1. The relative position accuracy of the holes cannot be guaranteed, and the cumulative tolerance of the workpiece is not easy to control, resulting in defective workpieces; 2. Low work efficiency.
