Description

Technical Field

[0001] This utility model relates to the field of milling technology, specifically a milling device for the eccentric shaft of an electric toothbrush. Background Technology

[0002] The eccentric shaft is an important component in a vibrating electric toothbrush, providing the vibration effect. The eccentric shaft of an electric toothbrush is manufactured using a milling machine.

[0003] In the prior art, patent announcement number CN222679620U discloses an eccentric shaft milling device for electric toothbrushes. The milling device includes a machine body, a control panel, a milling head, and an eccentric shaft material. The control panel is installed on the side surface of the machine body, and a sliding sleeve is slidably connected to the inner wall of the machine body. A first support seat is installed on the upper surface of the sliding sleeve, and a second support seat is connected to the upper surface of the first support seat. A fixed seat is installed on the upper surface of the second support seat, and a material fixing block is installed on the upper surface of the fixed seat. The eccentric shaft material is inserted into the inside of the material fixing block, and a milling head is provided inside the machine body.

[0004] The aforementioned device uses material fixing blocks to secure the eccentric shaft raw material. Before processing, workers must first correctly place and clamp the raw material into the material fixing blocks, a process requiring careful operation to ensure the stability and safety of the material. After processing, workers intervene again to remove the finished workpiece from the machine. Throughout the loading and unloading process, workers need to operate frequently, increasing their labor intensity, and the high level of manual intervention results in a relatively slow overall processing speed. Therefore, a milling device for electric toothbrush eccentric shafts is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a milling device for the eccentric shaft of an electric toothbrush to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an eccentric shaft milling device for electric toothbrushes, comprising an X-axis slide, a Y-axis slide mounted on the X-axis slide, a Z-axis slide fixedly mounted at the end of the X-axis slide, a milling assembly mounted on the Z-axis slide, and a feeding mechanism mounted on the Y-axis slide. The feeding mechanism includes a slide block slidably mounted on the X-axis slide, a material fixing block fixedly mounted on the slide block, a mounting frame fixedly mounted on one side of the material fixing block, an electric push rod fixedly mounted on the mounting frame, a pressure rod fixedly mounted at the output end of the electric push rod, and a unloading mechanism provided between the mounting frame and the pressure rod.

[0007] Preferably, a discharge chute is fixedly installed at the end of the Y-axis slide, a material box is fixedly installed on one side of the material fixing block, the material box stores eccentric shaft raw materials, and an arc-shaped support plate is fixedly installed below the material box.

[0008] Preferably, the material fixing block has a feed inlet on one side, and the material fixing block enters the interior of the material fixing block through the feed inlet. The milling assembly is movably mounted on the Y-axis slide via the Z-axis slide.

[0009] Preferably, the electric push rod is fixedly installed on one side of the material fixing block by a mounting bracket, the material fixing block is movably installed above the Y-axis slide by a slide block slider, and the pressure rod is movably installed on one side of the material fixing block by an electric push rod, with the pressure rod aligned with the feed port on the material fixing block.

[0010] Preferably, the unloading mechanism includes a positioning sleeve fixedly installed on the mounting frame and a strong magnet fixedly installed at the end of the pressure rod. The positioning sleeve is provided with a fixed support foot, and a protective cover is fixedly installed on the fixed support foot. A magnetizing coil is fixedly installed inside the protective cover, and the output end of the electric push rod passes through the magnetizing coil.

[0011] Preferably, the end of the pressure rod is provided with a mounting groove, and the strong magnet is mounted to the end of the pressure rod through the mounting groove.

[0012] Preferably, the protective cover is fixed to the positioning sleeve by a fixed support foot, and the magnetizing coil is installed inside the mounting frame through the protective cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, under the influence of gravity, the eccentric shaft material in the hopper descends into the arc-shaped support plate. Subsequently, an electric push rod can be activated, which drives the pressure rod to move forward, thereby pushing the eccentric shaft material into the material fixing block and fixing it. Once the eccentric shaft material is fixed, the material can be moved below the milling assembly using the X-axis and Y-axis slides to perform the milling operation.

[0015] 2. In this application, after the slide block resets, the electric push rod can retract. During the retraction of the electric push rod, the strong magnet attracts the processed eccentric shaft material, causing the material to detach from the material fixing block and move above the unloading chute. Subsequently, a current can be applied to the magnetizing coil to magnetize the eccentric shaft material. Due to the magnetization, the eccentric shaft material and the strong magnet generate a repulsive force, thereby separating the eccentric shaft material from the strong magnet. The separated eccentric shaft material will fall into the unloading chute, completing the automatic unloading process and thus improving processing efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an eccentric shaft milling processing device for electric toothbrushes, including an X-axis slide 1, a Y-axis slide 2 mounted on the X-axis slide 1, a Z-axis slide 4 fixedly mounted at the end of the X-axis slide 1, a milling assembly 3 mounted on the Z-axis slide 4, a feeding mechanism 5 mounted on the Y-axis slide 2, and a unloading mechanism 6 provided between the mounting frame 504 and the pressure rod 506. Through the cooperation of the feeding mechanism 5 and the unloading mechanism 6, automatic loading and unloading can be realized, thereby improving the processing speed.

[0023] like Figure 2 and Figure 3As shown, the feeding mechanism 5 includes a slide block 501 slidably mounted on the X-axis slide 1. A material fixing block 502 is fixedly mounted on the slide block 501. A mounting frame 504 is fixedly mounted on one side of the material fixing block 502. An electric push rod 505 is fixedly mounted on the mounting frame 504. A pressure rod 506 is fixedly mounted at the output end of the electric push rod 505. A discharge chute 7 is fixedly mounted at the end of the Y-axis slide 2. A material box 503 is fixedly mounted on one side of the material fixing block 502. The material box 503 stores eccentric shaft raw material 8. An arc support plate 507 is fixedly mounted below the material box 503. A feed port is opened on one side of the material fixing block 502. The material fixing block 502 enters the interior of the material fixing block 502 through the feed port. The milling assembly 3 is movably mounted above the Y-axis slide 2 via the Z-axis slide 4.

[0024] Specifically, under the influence of gravity, the eccentric shaft material 8 in the hopper 503 will naturally fall into the arc-shaped support plate 507. Once the eccentric shaft material 8 has completely fallen into the arc-shaped support plate 507, the electric push rod 505 can be activated. Once activated, the electric push rod 505 will drive the pressure rod 506 forward. This forward movement will push the eccentric shaft material 8 into the material fixing block 502 and secure it there. Once the eccentric shaft material 8 is securely fixed, it can be moved below the milling assembly 3 through the coordinated work of the X-axis slide 1 and the Y-axis slide 2. Below the milling assembly 3, the eccentric shaft material 8 will undergo precise milling to complete its processing.

[0025] like Figure 2 and Figure 4 As shown, the unloading mechanism 6 includes a positioning sleeve 602 fixedly installed on the mounting frame 504 and a strong magnet 605 fixedly installed on the end of the pressure rod 506. The positioning sleeve 602 is provided with a fixed support foot 603, and a protective cover 601 is fixedly installed on the fixed support foot 603. A magnetizing coil 604 is fixedly installed inside the protective cover 601, and the output end of the electric push rod 505 passes through the magnetizing coil 604. The end of the pressure rod 506 is provided with a mounting groove, and the strong magnet 605 is installed on the end of the pressure rod 506 through the mounting groove.

[0026] Specifically, after the slide block 501 completes its reset action, it can effectively retract the electric push rod 505. During the retraction process, the magnetic force of the strong magnet 605 acts on the eccentric shaft material 8, causing it to detach from its original position fixed on the material fixing block 502 and move above the unloading chute 7. Then, the magnetizing coil 604 can be energized to magnetize the eccentric shaft material 8. Once magnetized, the eccentric shaft material 8 will generate magnetic repulsion with the strong magnet 605, thus separating it from the magnet. After separation, the eccentric shaft material 8 will fall into the unloading chute 7 due to gravity, completing the automatic unloading process. This series of actions not only improves processing efficiency but also optimizes the automation level of the entire processing flow.

[0027] Working principle: When in use, first place the eccentric shaft material 8 in the material box 503. Under the action of gravity, the eccentric shaft material 8 in the material box 503 will fall into the arc support plate 507. After the eccentric shaft material 8 falls into the arc support plate 507, the electric push rod 505 can be started. After starting the electric push rod 505, it will drive the pressure rod 506 to move forward, thereby pushing the eccentric shaft material 8 into the material fixing block 502 and fixing it. After the eccentric shaft material 8 is fixed, the X-axis slide table 1 and Y-axis slide table 2 can be used to move the eccentric shaft material 8 to the bottom of the milling assembly 3 for milling operation. After the milling operation is completed, the slide block 501 can be controlled to reset. After the slide block 501 is reset, the electric push rod 505 can be retracted. During the retraction of the electric push rod 505, the strong magnet 605 will attract the machined eccentric shaft material 8, causing the machined eccentric shaft material 8 to detach from the material fixing block 502 and move to the top of the unloading chute 7. After the eccentric shaft material 8 moves to the top of the unloading chute 7, the magnetizing coil 604 can be energized to magnetize the eccentric shaft material 8, which will repel the strong magnet 605, thus separating the eccentric shaft material 8 from the strong magnet 605. After the eccentric shaft material 8 is separated from the strong magnet 605, it will fall into the unloading chute 7, realizing automatic unloading and improving the processing speed.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
