Description

Technical Field

[0001] The utility model relates to the technical field of torque converter pump wheel feeding and conveying, and specifically discloses a torque converter pump wheel feeding and conveying device. Background Art

[0002] The hydraulic torque converter is also called "hydraulic torque converter", "turbine torque converter" and "dynamic hydraulic torque converter". It is a kind of hydraulic transmission component. It consists of a pump wheel, a turbine and a guide wheel. The pump wheel is generally cast from aluminum metal, and many relatively flat blades are radially installed inside. The inner edge of the blade is equipped with a guide ring to allow the transmission oil to flow smoothly. It is made (or welded) into one piece with the torque converter housing and connected to the engine. A through hole is set in the middle of the pump wheel to facilitate the setting of the transmission shaft. At present, in the processing and production process of the torque converter, it is basically a single-process production. After the turning process is completed, the workpiece is manually transported to a mobile cart, and then the workpiece is transferred to the next process for subsequent processing using the mobile cart. The pump wheel process is cumbersome, requires multiple transfers, and has a long turnover distance.

[0003] In order to solve this problem, the patent with publication number CN115489997A discloses a torque converter housing processing production line, which relates to the field of torque converter production lines. It aims to solve the problems of slow production progress and high scrap rate caused by the low degree of automation in the current torque converter production. It includes an automated loading and unloading system, a robot transportation system, and an automated fixture system; the workpiece is positioned and clamped at three different workstations through the automated fixture system, and the setting of the transfer mechanism is conducive to the robot claw grasping the workpiece for processing on both sides.

[0004] In the above scheme, the torque converter housing can be transported using the material frame, but when an industrial robot is used to pick up and place the housing or pump wheel at the bottom of the material frame, interference is likely to occur, causing inconvenience in picking up and placing; in order to facilitate picking up and placing, a gap is left between the housing or pump wheel and the material frame, which may easily cause bumps and damage to the pump wheel during transportation.
