Description

Technical Field

[0001] The utility model relates to the technical field of steering transmission shafts, in particular to a clamping device used for producing steering transmission shafts of harvesters. Background Art

[0002] The steering drive shaft is a key component in the machine. It is responsible for transmitting power from the engine or drive device to the steering system to ensure that the machine can flexibly turn and adapt to different environments. The design of the harvester steering shaft is crucial to improving the maneuverability of the harvester and reducing labor intensity. When the harvester steering drive shaft is produced, it is necessary to punch holes on the harvester steering shaft. In order to ensure that the harvester steering shaft is more stable during processing, a clamping device is generally used to clamp and fix it.

[0003] According to the utility model with authorization announcement number CN208514099U, a steering transmission shaft processing fixture is disclosed. Although the dynamic component of the device drives the second mounting seat to move along the slide groove close to the first mounting seat through a rope to adjust the distance between the two, so as to be suitable for clamping transmission shafts of different specifications; the stability of the second mounting seat during movement is increased by a guide rod. The utility model has a simple structure and can effectively adjust the distance between the first mounting seat and the second mounting seat to be suitable for clamping transmission shafts of different specifications. However, when the device is used, since different positions of the steering shaft need to be processed, workers are required to manually remove the steering shaft from the clamping device many times, flip it over and then fix it on the clamping device, which causes certain inconveniences. For this reason, we provide a clamping device for the production of harvester steering transmission shafts to solve the above problems. Utility Model Content
