Description

Technical Field

[0001] The utility model relates to the technical field of assembly machines, in particular to a precisely positioned five-piece automatic assembly device for a pump core. Background Art

[0002] The pump core assembly machine can automatically complete the entire process of loading and unloading all components of the pump core through preset programs and precise actuators. It is one of the core equipment in the field of modern pump manufacturing. The five-piece set of the pump core includes the lower pump column, piston, lock cover, spring and upper pump column, among which the spring needs to be sleeved on the outside of the upper pump column.

[0003] In the prior art, when the pump core assembly machine is loading the spring, it is difficult for the spring to maintain a vertical posture due to the physical properties of the spring itself and the mutual extrusion and accumulation. Due to bending deformation, it is difficult to dock with the upper pump column, and it cannot be completely fitted onto the outside of the upper pump column, resulting in installation failure or even device blockage, reducing the assembly machine's alignment accuracy and product quality. Utility Model Content

[0004] The utility model discloses a precisely positioned five-piece automatic assembly device for a pump core, aiming to solve the technical problem that a spring is easily bent and deformed, making it difficult to connect with an upper pump column and even unable to be completely sleeved on the outside of the upper pump column.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a precisely positioned five-piece automatic assembly device for a pump core, comprising a fixed platform; an installation turntable, the installation turntable is movably connected to the upper end surface of the fixed platform; a fixed ring frame, the fixed ring frame is fixedly connected to the top of the fixed platform; a mounting frame, the mounting frame is fixedly connected to the fixed ring frame; a positioning operation module, the positioning operation module is arranged on the mounting frame, the positioning operation module comprises a fixed seat, a fixing hole is provided on the mounting frame, the fixing seat is fixedly connected to the fixing hole, the fixing seat is provided with two sliding slots, the two sliding slots are slidably connected to sliding rods, the outsides of the two sliding rods are slidably connected to flexible clamps, and the two flexible clamps are symmetrical to each other; a lifting auxiliary module, the lifting auxiliary module is arranged on the fixed platform and the installation turntable, the lifting auxiliary module The cam is connected to the upper end face of the fixing plate, and the fixing plate is connected to the fixing plate by a toothed connecting strip which is cooperatively connected with the fixing plate.

[0006] By providing a positioning operation module, after the spring falls between the two flexible clamping parts, the servo motor is started to rotate the transmission gear, and the mutual engagement of the transmission gear and the transmission gear ring drives the movable seat to rotate, forcing the sliding part to slide in the arc-shaped slot, driving the sliding rod and the flexible clamping part to move in opposite directions, and keeping the spring vertical during the flexible clamping process. The electric telescopic rod is started to push the flexible clamping part to drive the spring down, so that the spring is accurately placed on the outside of the upper pump column; the flexible clamping part is used to forcibly correct and maintain the vertical posture of the spring, and at the same time, the spring is accurately lowered to complete the socketing, which can avoid the spring in a bent state from being unable to be sleeved on the outside of the upper pump column, resulting in installation failure, thereby improving assembly accuracy and assembly quality.

[0007] In a preferred embodiment, the lifting auxiliary module also includes a lifting rod, multiple lifting rods all slide on the inner wall of the corresponding conical sliding sleeve, and the upper ends of the multiple lifting rods are fixedly connected to the limiting parts, the lower ends of the multiple lifting rods are fixedly connected to the sliding seat, the upper end surface of the fixed platform is fixedly connected to the sliding ring frame, the multiple sliding seats all slide above the sliding ring frame, the bottoms of the multiple conical sliding sleeves are fixedly connected to the return springs, the multiple return springs all surround the outside of the corresponding lifting rods, and the ends of the multiple return springs away from the conical sliding sleeves are fixedly connected to the upper end surface of the corresponding sliding seat, the fixed platform is fixedly connected to a drive motor, and the output end of the drive motor is fixedly connected to the bottom of the mounting turntable, the upper end surface of the mounting frame is provided with a spring feed rail, and the upper end surface of the fixed ring frame is provided with an upper pump column feed rail.

[0008] By providing a lifting auxiliary module, the upper pump column reaches the upper part of the corresponding mounting seat from the upper pump column feed rail and falls into the conical sleeve. Through the guiding effect of the conical surface of the inner wall of the conical sleeve, the upper pump column slides to the center of the conical sleeve during the falling process until it falls on the limit piece. The inner wall of the upper pump column is supported by the limit piece, which can avoid the situation that the upper pump column feeding is prone to tilting when the limit groove space is large. During the rotation of the installation turntable, since the sliding seat slides above the sliding ring frame, the sliding seat gradually overcomes the elastic effect of the return spring under the guiding action of the sliding ring frame to push the lifting rod and the limit piece to rise, thereby driving the upper pump column to rise; the guidance and limit piece support of the conical sleeve can ensure that the upper pump column falls accurately in the center, keeps it vertically fixed, and effectively prevents tilting. At the same time, the sliding ring frame is used to link the lifting rod to lift the upper pump column, creating space for spring assembly.

[0009] From the above, it can be seen that the utility model provides a precisely positioned five-piece automatic assembly device for a pump core, which uses a positioning operation module and a flexible clamping part to forcibly correct and maintain the vertical posture of the spring, while accurately lowering the spring to complete the connection. This can avoid the bent spring from being unable to be fitted onto the outside of the upper pump column, resulting in installation failure, and improve assembly accuracy and quality.
