Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a tool for detecting the strength of a water pump connecting rod of a water jet loom. Background Art

[0002] The water jet loom uses water as the weft insertion medium. The water jet generates frictional traction on the weft yarn, driving the weft yarn into the shed and interweaving with the warp yarn to form a fabric. The weft insertion system of the water jet loom includes a plunger pump with a one-way valve installed at the inlet and outlet ends, an inlet pipe connected to the inlet channel of the plunger pump, an outlet pipe connected to the outlet channel of the plunger pump, and a nozzle connected to the outlet pipe. The plunger pump relies on the reciprocating motion of the plunger in the cylinder body to change the volume of the sealed working chamber to achieve liquid suction and liquid pressure; it has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment. CN208933591U discloses a double-spring weft insertion water pump for a water jet loom. The water pump is connected to a power connecting rod through a connecting plate and a joint. The movement of the power connecting rod acts on the water pump, so that the water pump sprays water. In actual use, the joint is connected to the water pump through a connecting rod. The connection between the joint and the connecting rod can withstand a large tensile force to ensure the normal operation of the water pump. Therefore, the connecting rod structure composed of the joint and the connecting rod needs to be tested for its tensile strength before leaving the factory. The utility model provides a water jet loom water pump connecting rod strength testing tool for testing the strength of the connecting rod. Utility Model Content

[0014] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0015] according to Figure 1-4 As shown, a water jet loom water pump connecting rod strength detection tool includes a base, the base includes two symmetrically arranged splicing seats 1, the splicing seat 1 includes a head 11 and a tail 12, the head 11 is provided with a placement groove 111, the placement grooves 111 of the two splicing seats 1 enclose a circular structure for placing a joint 7, the placement groove 111 is connected to a square groove 112 allowing a connecting rod 8 to pass through, and the tail 12 of the splicing seat 1 is provided with a pulling protrusion 121.
