Description
Technical Field
The utility model relates to the technical field of manufacturing tools, in particular to a forged tee turning preassembling clamp.
Background
The high-pressure forged tee joint and cross joint are mainly formed by die-pressing forging blanks of round steel or steel ingots and then machining and forming the high-pressure pipeline connecting fittings by a lathe. When a square forged three-way blank is used for cutting, a middle pipeline is usually turned on a lathe, and a four-jaw chuck is required for clamping. Because the surface quality of the forged blank is different, the shape precision is poor, the clamping surface is unstable, the circular boss is machined discontinuously, the impact force of a cutter and a workpiece is large, the requirement on the clamping force of the blank is high, the problems of cutter damage and workpiece scrapping caused by looseness of the blank in the machining process can occur, or in order to achieve machining safety, only the machining parameters can be reduced, and the machining efficiency is greatly reduced. Meanwhile, the four claws are used for clamping and forging the blank, and each part needs to be aligned, so that the machining efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the existing problems, the utility model provides a forged three-way turning preassembly clamp.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a forge tee bend turning pre-installation anchor clamps, includes framework and thimble, the inner chamber of framework is greater than the appearance of tee bend blank, the thimble sets up the middle part in four sides of framework, the middle part in four sides of framework is equipped with the screw thread through-hole, thimble and framework threaded connection, the one end of thimble is equipped with most advanced, and its other end is equipped with the adjustment tank, just most advanced is located inner chamber one side of framework, the thimble of every side all is equipped with threely at least, and is not located a straight line.
Specifically, the inner cavity of the frame body is matched with the appearance of the tee-joint blank body, a small gap is reserved between the frame body and the tee-joint blank body, all ejector pins are withdrawn before installation, then the tee-joint blank body is placed into the frame body, all ejector pins are sequentially locked, the influence of errors of the installation surface shape of the tee-joint blank body is eliminated, then the frame body and the tee-joint blank body are installed on a four-jaw chuck together, four clamping jaws of the four-jaw chuck are respectively clamped in the middle of four side faces of the frame body, the tip end of each ejector pin is pressed into the surface of the tee-joint blank body, the ejector pins and the frame body are rigidly connected with the four-jaw chuck through compression deformation of the frame body, a stable clamping state is kept, and machining efficiency requirements and safety are effectively guaranteed.
According to another embodiment of the present invention, further comprising that the middle of the four side surfaces of the frame body is provided with a thickened portion. Through setting up thickening portion, increase the adjustment range of thimble and the threaded connection department length of thimble and framework, guarantee clamping strength, can suitably reduce the thickness at other positions of framework simultaneously, when guaranteeing that the jack catch presss from both sides tightly, further strengthen the combination of thimble and tee bend body.
According to another embodiment of the present invention, it is further included that the adjustment groove is an inner hexagonal groove.
According to another embodiment of the present invention, the thimble is made of bearing steel, and the tip of the thimble is quenched. The durability of the thimble is improved by selecting high-strength materials and hardening the tip.
The utility model has the advantages that the position of the thimble can be adjusted to adapt to the tee-joint green body through the frame body and thimble structure, the influence of the shape error of the installation surface of the tee-joint green body is eliminated, the tee-joint green body, the thimble and the frame body are rigidly connected with the four-jaw chuck through the compression deformation of the frame body, the stable clamping state of the tee-joint green body is kept, the requirement and the safety of the processing efficiency are effectively ensured, meanwhile, a plurality of sets of preassembly fixtures can be configured, parts are preassembled when the equipment runs, the appearance of the frame body is regular and high in precision, the four-jaw chuck is convenient to clamp and avoid alignment, and the processing efficiency is improved.
