Automatic pipe grasping device

Abstract

The invention relates to a pipe grasping device, in particular to an automatic tube grasping device used for grasping a vertically hung U-shaped pipe. The automatic pipe grasping device comprises a bracket and a plurality of clamping jaws; each clamping jaw comprises a top clamp seat, a transmission element and a pair of clamping boards; the clamp seats of the clamping jaws are arranged on the bracket in parallel; the transmission elements are connected with the clamping boards; the transmission elements are arranged on the clamp seats; the transmission elements can drive the clamping boards to rotate around the axial lines of the transmission elements; the clamping boards are controlled to be on and off through clamping jaw driving devices; the transmission elements are connected with directional control devices; and the directional control devices control the transmission elements to rotate. The automatic pipe grasping device provided by the invention can be used for realizing that multiple vertically-hung long U-shaped copper pipes are simultaneously grasped, the grasping way is simple and efficient, the device is light and convenient, the structure is compact, the occupied space is small, and the copper pipes cannot be distorted, thus, the condition for automatically feeding pipes efficiently is realized, and the guarantee for breaking through efficient and automatic pipe sleeving technique is provided.

Description

technical field [0001] The invention relates to a pipe grasping device, in particular to an automatic pipe grasping device for grasping vertically suspended U-shaped pipes. Background technique [0002] In the heat exchanger production process, the tube threading process is undoubtedly a very important step. Taking the heat exchanger of the air conditioner as an example, there are generally hundreds of extremely thin aluminum fins and several Ten thin-walled copper tubes. At present, the pipe threading process is completed manually in the industry. This method has low efficiency, high labor cost, and high labor intensity; therefore, it is of great significance to realize the automation of pipe threading. In the finned heat exchanger, the thickness of the U-shaped copper tube used is 0.25~0.3mm, which is poor in rigidity and easily deformed. Therefore, to break through the efficient automatic tube insertion technology, the realization of automatic tube loading is particularl...
