Double-speed chain tool plate positioning device

Abstract

The invention discloses a double-speed chain tool plate positioning device. The device comprises a tool plate, lifting positioning mechanisms and a stop mechanism. According to the device, a tool plate running on a double-speed chain is blocked through the stop mechanism, the lifting positioning mechanisms at the two ends are pushed under the driving of pushing air cylinders, a bearing and a positioning pin are matched with a positioning block on the tool plate, the propelling action is stopped under the action of mechanical limiting, after the working procedure of the station is completed bythe tool plate, the lifting positioning module returns under the action of the air cylinders, the stop mechanism descends, the tool plate makes contact with a transmission part of the double-speed chain again, and then the tool plate moves to the next station. The repeated positioning precision of the device is high, and the risk of product badness caused by abrasion of the contact part of the tool plate or the double-speed chain can be reduced. The device is suitable for production of a fuel tank.

Description

technical field [0001] The invention relates to the technical field of double-speed chain tooling plate processing, in particular to a double-speed chain tooling plate positioning device. Background technique [0002] In the existing double-speed chain transmission system, it usually directly blocks the tooling running on it to achieve the stop function, or assists in the jacking with low matching accuracy. When this method is applied to the welding process of the fuel tank opening, there are The following deficiencies: [0003] 1. Insufficient repeat positioning accuracy, which leads to lack of consistency in the processing state, which in turn leads to poor welding of the fuel tank opening, and even causes a major quality risk of fuel tank leakage; [0004] 2. The lateral support force is insufficient, and there is a risk that the tooling plate will be deflected when the fuel tank is drilled or welded laterally. Contents of the invention [0005] Aiming at the problems...
