TECHNICAL FIELD
[0001] The utility model belongs to the technical field of clamp, and relates to a slip for geothermal pump hot melting welding. BACKGROUND
[0002] The geothermal pump, also called the geothermal source pump, is a common structure in today's life, which generally comprises an external shell and a plurality of components installed in the shell. Since internal parts need to be installed separately, the shell cannot be directly injection molded in one piece, but needs to be made into two head and tail parts through a special mold. After the installation of the parts is completed, the head and the tail are welded in one piece by butt joint, so that a complete geothermal pump is obtained.
[0003] The butt welding quality is related to the product quality of the geothermal pump. In the prior art, a special support is generally used to assemble the head and the tail of the shell. Specifically, the support generally comprises a base and two slide rails fixed on the base in the transverse direction. An installation seat is connected between the two slide rails in the length direction. Two slips are fixed in the two installation seats. One of the installation seats is fixed between the two slide rails, and the other installation seat is slidingly connected between the two slide rails.
[0004] Further, the installation seat is divided into an upper installation seat and a lower installation seat which are locked by bolts. The slip is also divided into an upper slip and a lower slip. The upper slip is fixed in the upper installation seat, and the lower slip is fixed in the lower installation seat. Before processing, the upper installation seat together with the upper slip is detached from the lower installation seat. The head or tail of the shell is placed in the lower slip of the lower installation seat. Then the upper installation seat and the lower installation seat are locked by bolt connection, so that the upper slip and the lower slip clamp the head or tail of the shell. During processing (it should be noted that the head and tail of the shell are heated in advance), one of the installation seats remains positioned, and the other installation seat moves along the slide rail, so that the head and tail of the engine abut against each other. After cooling and solidification, they are connected in one piece.
[0005] In actual production process, the positioning of the head and tail of the shell in the circumferential and axial directions is very important. In the prior art, the positioning of the head and tail of the shell in the circumferential direction is realized by the inner wall of the slip, and the positioning in the axial direction is realized by the cooperation of the upper slip and the lower slip. However, due to the pressure factor acting between the two during butt welding, the head and tail of the shell are often pushed and displaced, which causes deviation of the welding work and seriously affects the processing qualification rate of the product.
