[0022] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.
[0023] In the description of the present invention, it is necessary to understand that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0024] In the description of the present invention, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meaning of the terms can be understood according to the specific circumstances.
[0025] like Figures 1 to 3 As shown, the preferred embodiment of the present invention is: a diaphragm maximum deformation positioning tool for a diaphragm pump, a connecting rod B is installed in the middle of the diaphragm A, the connecting rod B includes a straight rod portion and a circular ring portion, the tool includes a base 40, and a diaphragm fixing mechanism 10, a connecting rod guiding mechanism 20 and a connecting rod tractor mechanism 30 installed at intervals on the base 40; the diaphragm fixing mechanism 10 includes two clamping plates for clamping the diaphragm, one of which is an L-shaped mounting plate 12, and the other is a pressing plate 11, and the mounting plate 12 and the pressing plate 11 are both provided with large circular through holes, and the pressing plate 11 is fixed to the mounting plate 12 by bolts after being fitted; the connecting rod guiding mechanism 20 includes a guide block 21, a column 22, a spring 23, and a height adjustment bolt 24, and the guide block 21 is installed on the column 22 At the upper end, a guide groove is provided at the upper end of the guide block 21, and a screw hole is provided at the lower end of the column 22. The height adjustment bolt 24 passes through the through hole of the base 40, is covered with a spring 23 and is screwed upward into the screw hole of the column 22; the connecting rod tractor mechanism 30 includes a support block 31, a drag block 32 and a lateral adjustment bolt 33. The upper part of the support block 31 is provided with a slide groove, a baffle and a scale 34. A light hole is opened on the baffle. The drag block 32 is a cylinder, and the side surface of the lower end is milled to form a limiting portion. The limiting portion is inserted into the slide groove of the support block 31. A screw hole with a height consistent with the light hole is opened on the drag block 32. The lateral adjustment bolt 33 passes through the light hole and is screwed into the screw hole of the drag block 32. A pointer 35 corresponding to the scale 34 is installed on the side of the drag block 32.

Since the connecting rod B is connected to the center of the diaphragm A, the movement of the connecting rod B can drive the diaphragm A to deform to one side until the maximum eccentricity of the diaphragm. Since the support block 31 is provided with a scale 34 and the drag block 32 is provided with a pointer 35, the pointer 35 is moved together when the drag block 32 moves, and the maximum deformation of the diaphragm of the diaphragm pump can be obtained by the movement of the pointer 35 on the scale 34.
