Description
Technical field
The utility model belongs to and relates to a kind of screw pump stator connecting head that screw pump stator connects that is used for.
Background technique
At present; The screw pump stator connecting head of existing technology comprises connecting sleeve that is rotatably connected on screw pump stator one end and the piece that is threaded that is connected the screw pump stator the other end, and connecting sleeve can be threaded with the piece that is threaded, but because the piece that is threaded all is to be welded on the screw pump stator; The piece that is threaded is that the loop configuration wall thickness is thinner; The high temperature that produces when then the welding piece easy deformation that is threaded makes the also distortion thereupon of screw thread on the piece outer peripheral surface of being threaded, thereby makes connecting sleeve to screw with the piece that is threaded; And then making that the assembly rate of the utility model is lower, assembly cost is higher.
The model utility content
The utility model provides a kind of piece that is not threaded on-deformable screw pump stator connecting head to above problem.
The utility model overcomes the above problems used technological scheme: a kind of screw pump stator connecting head with following structure is provided; It comprises the contiguous block of connecting sleeve that is rotationally connected with screw pump stator one end and the annular that is connected with the screw pump stator the other end; The inwall of described connecting sleeve and contiguous block outer circumferential face are equipped with screw thread; Described connecting sleeve can screw with contiguous block; The inwall of described contiguous block also is provided with screw thread, and the screw pump stator the other end also is provided with the outside thread that is connected with the inner thread of contiguous block.
After adopting above structure, compared with prior art, the utility model is because the inwall of contiguous block also is provided with screw thread; And the screw pump stator the other end also is provided with the outside thread that is connected with the inner thread of the piece that is threaded, and the piece that then is threaded directly is threaded with the screw pump stator the other end and gets final product, and need not to be welded to connect again; Occur so just do not have the situation of high temperature when connecting, the feasible piece that is threaded is not yielding, and the assembling speed that is threaded will be higher than the speed of welding yet; Manufacturing efficiency is higher, the consumption of also having saved welding wire and electric power simultaneously, and energy consumption is less; And then reduce production costs, so make that the efficiency of assembling of the utility model is higher, assembly cost is lower.
As improvement, described connecting sleeve is provided with first through hole, and described contiguous block is provided with second through hole; The described screw pump stator the other end is provided with counterbore; With after connecting sleeve and screw pump stator are connected, the axis of the axis of first through hole, second through hole and the axis of counterbore are all on same straight line, then when the two ends screw pump stator is connected at contiguous block; After contiguous block and connecting sleeve and screw pump stator all screw; Because the axis of the axis of first through hole, second through hole and the axis of counterbore all on same straight line, can insert locating stud and position in the hole that first through hole, second through hole and counterbore are formed, make screw thread place after the utility model assembling be difficult for occurring in actual use situation about getting loose; Stability in use is better, and working life is longer.
Description of drawings
Fig. 1 is the structural representation of the utility model screw pump stator connecting head.
Fig. 2 is the structure for amplifying schematic representation of A part among Fig. 1.
As shown in the figure: 1, screw pump stator, 2, connecting sleeve, 3, contiguous block, 4, first through hole, 5, counterbore, 6, second through hole.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model done further describing.
A kind of screw pump stator connecting head as depicted in figs. 1 and 2; It comprises the contiguous block 3 of connecting sleeve 2 that is rotationally connected with screw pump stator 1 one ends and the annular that is connected with screw pump stator 1 the other end; The inwall of described connecting sleeve 2 and contiguous block 3 outer circumferential faces are equipped with screw thread; Described connecting sleeve 2 can screw with contiguous block 3, and the inwall of described contiguous block 3 also is provided with screw thread, and screw pump stator 1 the other end also is provided with the outside thread that is connected with the inner thread of contiguous block 3.
Described connecting sleeve 2 is provided with first through hole 4; Described contiguous block 3 is provided with second through hole 6; Described screw pump stator 1 the other end is provided with counterbore 5; With after connecting sleeve 2 and screw pump stator 1 are connected, the axis of the axis of first through hole 4, second through hole 6 and the axis of counterbore 5 are all on same straight line at contiguous block 3.Generally to be connected rear stability better for connecting sleeve 2 and connecting sleeve 2 and screw pump stator 1; The one group of positioning hole that is combined as with one first through hole 4, second through hole 6 and counterbore 5; At least two group positioning holes all are set, four groups of positioning holes are set usually, and every group of positioning hole is along circumferentially evenly distributing.
During assembling; Earlier connecting sleeve 2 is inserted in screw pump stator 1 from the end that screw pump stator 1 needs to connect contiguous block 3; Because be provided with radial protrusion near screw pump stator 1 and the end that connecting sleeve 2 is connected, for the inwall of connecting sleeve 2 also is provided with the step that cooperates with this convexity to connecting sleeve 2 axial limitings; Subsequently contiguous block 3 is screwed on the outside thread of screw pump stator 1 and get final product.In the time of need two screw pump stators 1 being linked together; Contiguous block 3 on connecting sleeve on the screw pump stator 12 and another root screw pump stator 1 is screwed; This moment first through hole 4 the axis of axis and counterbore 5 of axis, second through hole 6 all on same straight line, and plug locating stud or rivet gets final product.
Above embodiment is merely the preferred embodiment of the utility model, and the utility model is not limited only to above embodiment and also allows other structural change, allly in the utility model rights to independence claimed range, changes, and all belongs to the utility model protection domain.
