[0002] Elbows are common components in washing machine water supply pipes, typically connected and assembled onto the pipe with nuts. However, current elbow assembly methods are mostly manual, which is labor-intensive and inefficient. A search reveals that Chinese utility model patent CN202322633805.7 discloses an automatic FR elbow assembly machine, comprising a shell feeding device, a pin feeding device, a core feeding device, a plug feeding device, a cap feeding device, a prong feeding device, a pin assembly device A, a pin assembly device B, a shell semi-finished product flow channel device, a turntable mounting device, a prong assembly device, an electrical testing device, a welding frame, and a protective cover. The welding frame has a pin assembly device A located near the shell feeding device, with the pin feeding device above it and the plug feeding device immediately to its left. The FR elbow automatic assembly machine described in this utility model has a high degree of automation, high production efficiency, and high production capacity. Tasks that traditionally required ten operators can now be completed by one operator. It is simple to operate, easy to adjust, has stable machine performance, and a high yield rate, reaching over 98%.

[0003] While the existing automatic elbow assembly machines can meet basic usage requirements, they lack flexibility and accuracy in accurately placing elbows into nuts by mimicking the elbow's arc curve. Therefore, further improvements to the existing technology are necessary. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cam mechanism for an elbow assembly machine, which, in view of the above-mentioned defects of the prior art, drives the clamp mounting plate to rotate by setting a rotary servo motor and a rotary shaft, and drives the clamps by a clamp cylinder, thereby clamping the elbow and placing it into the nut. It can accurately place the elbow into the nut by mimicking the arc curve of the elbow, and can achieve high-precision position control and high flexibility.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A cam mechanism for an elbow assembly machine includes a fixed base, on which a transverse cylinder and a lifting mechanism mounting plate driven by the transverse cylinder are mounted. The lifting mechanism mounting plate is equipped with a lifting servo motor and a rotating mechanism mounting plate driven by the lifting servo motor. The rotating mechanism mounting plate is equipped with a rotating servo motor and a rotating shaft driven by the rotating servo motor. A gripper mounting plate is mounted on the rotating shaft, and the gripper mounting plate is equipped with a plurality of gripper cylinders and grippers driven by the gripper cylinders.

[0007] Preferably, the gripper mounting plate is provided with a positioning shaft, which is located in the middle of the gripper.

[0008] Preferably, the rotary servo motor is connected to the rotary shaft via a rotary synchronous belt, and the rotary mechanism mounting plate is provided with a plurality of rotary limit posts.

[0009] Preferably, the lifting mechanism mounting plate is provided with a lifting linear guide rail, and a plurality of lifting sliders are slidably mounted on the lifting linear guide rail. The output end of the lifting servo motor is driven by a lifting synchronous belt, and the rotating mechanism mounting plate is connected to the lifting sliders and the lifting synchronous belt respectively.

[0010] Preferably, the lifting mechanism mounting plate is provided with a plurality of lifting limit blocks, which are located on the side of the rotating mechanism mounting plate.

[0011] Preferably, the fixed base is provided with a transverse linear guide rail, and a plurality of transverse sliders are slidably mounted on the transverse linear guide rail. The lifting mechanism mounting plate is mounted on the transverse sliders, and the output end of the transverse cylinder is connected to the lifting mechanism mounting plate through a floating joint.

[0012] The cam mechanism for an elbow assembly machine provided by this utility model, using the above technical solution, has the following beneficial effects: A horizontal cylinder and a lifting mechanism mounting plate connected to the horizontal cylinder are provided on the fixed seat of the cam mechanism. A lifting servo motor and a rotating mechanism mounting plate connected to the lifting servo motor are provided on the lifting mechanism mounting plate. A rotating servo motor and a rotating shaft connected to the rotating servo motor are provided on the rotating shaft.

Detailed Implementation

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0022] like Figure 1-5 As shown, the cam mechanism of the elbow assembly machine includes a fixed base 1, on which a transverse cylinder 2 and a lifting mechanism mounting plate 3 connected to the transverse cylinder 2 are mounted. The lifting mechanism mounting plate 3 is equipped with a lifting servo motor 4 and a rotating mechanism mounting plate 5 connected to the lifting servo motor 4. The rotating mechanism mounting plate 5 is equipped with a rotating servo motor 6 and a rotating shaft 7 connected to the rotating servo motor 6. A gripper mounting plate 8 is mounted on the rotating shaft 7, and several gripper cylinders 9 and grippers 10 connected to the gripper cylinders 9 are mounted on the gripper mounting plate 8. It is understood that the transverse cylinder 2 and the gripper cylinders 9 can be general-purpose cylinders, and the lifting servo motor 4 and the rotating servo motor 6 can be general-purpose servo motors. This cam mechanism, as part of the elbow assembly machine, is mainly used to grip the elbows on the elbow feeding mechanism and place them into the nuts located on the turntable of the elbow assembly machine.

[0023] Specifically, the gripper mounting plate 8 is provided with a positioning shaft 11, which is located in the middle of the gripper 10; the rotary servo motor 6 is connected to the rotary shaft 7 via a rotary synchronous belt 12; the rotary mechanism mounting plate 5 is provided with several rotary limit posts 13; the lifting mechanism mounting plate 5 is provided with a lifting linear guide rail 14, on which several lifting sliders 15 are slidably mounted; the output end of the lifting servo motor 4 is connected to a lifting synchronous belt 16; the rotary mechanism mounting plate 5 is connected to the lifting... The slider 15 and the lifting synchronous belt 16 are connected; the lifting mechanism mounting plate 3 is provided with a number of lifting limit blocks 17, which are located on the side of the rotating mechanism mounting plate 5; the fixed base 1 is provided with a transverse linear guide rail 18, and a number of transverse sliders 19 are slidably installed on the transverse linear guide rail 18. The lifting mechanism mounting plate 5 is installed on the transverse sliders 19. The output end of the transverse cylinder 2 is connected to the lifting mechanism mounting plate 5 through a floating joint 20. The fixed base 1 is provided with a number of transverse limit blocks 21. Understandably, during operation, the transverse cylinder 2 pushes the lifting mechanism mounting plate 3, causing it to move laterally along the transverse linear guide rail 18. The lifting servo motor 4 drives the lifting synchronous belt 16 to move, which in turn drives the rotating mechanism mounting plate 5 to move up and down along the lifting linear guide rail 14. The rotating servo motor 6 drives the rotating shaft 7 to rotate, which in turn drives the gripper mounting plate 8 to rotate. The gripper cylinder 9 drives the gripper 10 to grip the elbow. The movement trajectory of the gripper 10 is as follows: the gripper 10 first descends and grips the elbow on the elbow loading mechanism, then rises a certain distance, then moves forward laterally to above the nut placed on the turntable, while rotating to a certain angle, then descends again until the elbow is inserted into the nut, and finally the gripper 10 is released so that the elbow is placed into the nut, and then it moves back, thus repeating the cycle.

[0024] Understandably, this utility model has a reasonable design and unique structure. By setting a rotary servo motor 6 and a rotary shaft 7 to drive the gripper mounting plate 8 to rotate, the rotation path is an arc curve. The gripper cylinder 10 drives the gripper 10, thereby gripping the elbow and placing it into the nut. It achieves the goal of accurately placing the elbow into the nut by mimicking the arc curve of the elbow. It can achieve high-precision position control, high flexibility, and can improve working accuracy and increase elbow assembly capacity.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
