Description

Technical Field

[0001] This utility model belongs to the field of metal workpiece assembly tooling technology, specifically relating to an intermittent magnesium rod feeding mechanism. Background Technology

[0002] The magnesium anode rod, also known as the anode rod, is primarily composed of magnesium. Inside the water heater's inner tank, it, along with the tank itself (which is mainly composed of iron), comes into contact with water, forming a galvanic cell due to chemical principles. Since the water inside the tank is not pure and contains various impurities and is somewhat corrosive, scale will form when the water temperature exceeds 40℃. Without the magnesium anode rod, the inner tank would corrode. To facilitate the connection between the magnesium anode rod and the water heater, a nut is often fitted to the end of the magnesium anode rod during manufacturing. Because water often flows through the magnesium anode rod during use, the fit between the nut and the rod must be seamless and tight; otherwise, leaks may occur during operation.

[0003] Patent application number 2015102789064, entitled "A Novel Assembly Device for Connecting Nuts and Magnesium Rods," discloses an assembly device for magnesium rods and nuts, using a chain to transport the magnesium rods for feeding. In practical use, the chain feeding efficiency is low, and the conveyor belt feeding speed is limited. Excessive speed can easily cause the magnesium rods to detach from the chain, making it difficult to meet the demands of high-efficiency production. Furthermore, the magnesium rods are prone to vibration and misalignment during conveyor belt transport, affecting assembly accuracy. Utility Model Content

[0022] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0023] See Figures 1-4 This embodiment provides an intermittent magnesium rod feeding mechanism, including a platform 1, an outer fixing plate 2, an inner feeding plate 3, a first crank drive mechanism, a second crank drive mechanism, and a drive motor 51.

[0024] The outer fixing plate 2 is symmetrically fixed on the platform 1. Several angular toothed grooves are opened on the upper edge of the outer fixing plate 2. The first crank drive mechanism includes a first rotating shaft 41, a first synchronous pulley 42, a second synchronous pulley 43, and a first crank 44. The first rotating shaft 41 is rotatably mounted on the platform 1 through a bearing seat. One end of the first crank 44 is connected to the first rotating shaft 41, and the other end of the first crank 44 is connected to the inner feeding plate 3. The first synchronous pulley 42 and the second synchronous pulley 43 are mounted on the first rotating shaft 41.

[0025] The second crank drive mechanism includes a second rotating shaft 61, a third synchronous pulley 62, and a second crank 63. The second rotating shaft 61 is rotatably mounted on the platform 1 via a bearing seat. One end of the second crank 63 is connected to the second rotating shaft 61, and the other end of the second crank 63 is connected to the inner feed plate 3. The third synchronous pulley 63 is mounted on the second rotating shaft 61.

[0026] The drive motor 51 is mounted on the platform 1. The output shaft of the drive motor 51 is equipped with the fourth synchronous pulley 52. ​​The fourth synchronous pulley 52 is connected to the first synchronous pulley 42 by synchronous belt drive. The second synchronous pulley 43 is connected to the third synchronous pulley 62 by synchronous belt drive.

[0027] The inner feeding plate 3 is symmetrically arranged on the left and right sides, and several trapezoidal grooves are opened on the inner feeding plate 3.

[0028] like Figure 3 As shown, two elongated holes 11 are provided on the platform 1, through which the inner feeding plate 3 can move up and down.

[0029] like Figure 2 As shown, the pressure roller 7 is mounted on the platform 1 via a bracket. The position of the pressure roller 7 can be adjusted up and down to adjust the tension of the timing belt.

[0030] like Figure 4 As shown, an arc-shaped hole 21 is provided on the outer fixing plate 2 to provide space for crank rotation.

[0031] Explanation of the feeding principle of the feeding mechanism: (e.g.) Figure 1 As shown, magnesium rod 9 is placed into the toothed groove of the outer fixed plate 2 from the upper position. The drive motor 51 drives the first crank drive mechanism and the second crank drive mechanism to rotate via the synchronous belt and synchronous pulley, which in turn drives the inner loading plate 3 to rotate. During the rotation, magnesium rod 9 enters the trapezoidal toothed groove of the inner loading plate 3. As the inner loading plate 3 rotates, it lifts magnesium rod 9 and moves it out of the toothed groove of the outer fixed plate 2. As the inner loading plate 3 continues to rotate, it moves forward and downward. During this process, magnesium rod 9 located in the trapezoidal toothed groove is transferred to the next toothed groove of the outer fixed plate. Thus, the transportation of magnesium rod from one toothed groove to another on the outer fixed plate is completed. The inner loading plate 3 moves in this cyclical manner, which can realize the intermittent forward movement of magnesium rods. The toothed groove of the outer fixed plate can be filled with magnesium rods, which are transported forward one after another.

[0032] The angular grooves on the outer fixing plate 2 can accurately position the magnesium rod, preparing it for subsequent assembly.
