Description
Technical Field
[0001] The utility model relates to the technical field of workpiece grinding equipment, in particular to an automatic feeding mechanism and a rotary disc grinder. Background Art
[0002] Magnets are primarily used in various fields such as sensors, instruments, electronics, electromechanics, medicine, education, automotive, aviation, and military technology. Depending on the metal composition of the magnet, its magnetic properties and, consequently, its applications, vary. Currently, magnets are manufactured using powder metallurgy. However, the surface roughness of powder metallurgy products often falls short of the required surface roughness, necessitating further surface grinding using a grinding machine. Magnets are generally manufactured using powder metallurgy, and after production, they are ground using a grinding machine to ensure that their thickness, length, or width meet design requirements.
[0003] As a type of grinding machine, a rotary disc grinder is provided with a rotating disc and a disc drive motor on the main frame. A plurality of workpiece positioning holes distributed along the circumference are opened on the rotating disc. A corresponding workpiece is installed in each workpiece positioning hole. The disc is driven by the disc drive motor to rotate. During the rotation process, the workpieces on the disc pass through the grinding channel in sequence, and the grinding channel is provided with an optional grinding wheel, so as to realize the grinding of the workpieces on the disc one by one.
[0004] In the prior art, workpieces are manually placed one by one on the disc. Before the disc rotates, a workpiece is placed in each positioning hole. The disc's drive motor then rotates the disc, forcing the workpiece through the grinding channel for grinding. After grinding, a dedicated push rod on the frame pushes the workpiece out. When a free positioning hole is reached and the disc rotates to the loading position, the disc's drive motor stops after a certain rotation angle. During this stop, the workpiece is manually placed into the corresponding positioning hole, allowing for individual workpiece loading. This manual loading method is not only time-consuming and labor-intensive, impacting work efficiency, but also poses safety risks. Summary of the Invention
[0005] In order to overcome at least one of the defects in the above-mentioned prior art, the utility model provides an automatic feeding mechanism and a turntable grinder. During the rotation of the turntable, the workpieces can be automatically transferred and assembled onto the turntable one by one. As the turntable rotates, the workpieces can be continuously ground, and the work efficiency is high.
[0006] The utility model provides an automatic feeding mechanism: it includes a mounting seat, a loading plate is provided on the mounting seat, the upper end of the loading plate is provided with a slide groove extending along its length direction, one end of the slide groove is provided with a discharge port, the loading plate is connected to a slide seat that can slide along its length direction, the slide seat is connected to a push plate, and the push plate is abutted against the back of the workpiece in the slide groove that is farthest from the discharge port, and the loading plate and / or the mounting seat are connected to a driving component for driving the push plate to move horizontally to drive the workpieces in the slide groove to pass through the discharge port one by one and enter the next workstation.

[0010] Furthermore, the drive assembly includes a first pulley, a second pulley, a pull rope, and a counterweight unit. The first pulley is connected to one end of the carrier plate near the discharge port, and the second pulley is connected to the other end of the carrier plate.

This structure is simple, does not require a power source, and is energy-efficient and environmentally friendly.
[0011] Preferably, the chute is a V-shaped chute, and the end of the push plate away from the slide extends into the chute. The V-shaped chute in the above structure can position the circular workpiece smoothly, and the friction resistance during the sliding of the workpiece is small.
[0012] As an improvement, the bottom of the carrier is connected to a linear guide extending along its length, and the lower end of the slide is connected to a slider that slides on the linear guide. In this improved structure, the carrier and slide are connected by the linear guide structure, which allows for smooth sliding without any jamming or noise.

[0023] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of the present application and are not intended to limit the scope of protection of the embodiments of the present application. Those skilled in the art may adjust them as needed to suit specific application scenarios.
[0024] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "fixed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.
[0025] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] See also Figures 1 to 5 As shown, an embodiment of the present application discloses an automatic feeding mechanism, which includes a mounting seat, on which a long strip of loading plate 1 is arranged, and the upper end of the loading plate 1 is provided with a slide 2 extending along its length direction, and one end of the slide 2 is provided with a discharge port, the loading plate 1 is connected to a slide 3 that can slide along its length direction, the slide 3 is connected to a push plate 4, and the push plate 4 is abutted against the back of the workpiece in the slide 2 that is farthest from the discharge port, and the loading plate 1 and / or the mounting seat are connected to a driving component for driving the push plate 4 to move horizontally to drive the workpieces in the slide 2 to pass through the discharge port one by one and enter the next workstation.
[0027] In the above structure, in the initial state, the slide 3 is moved to the set position toward the side away from the discharge port, and then multiple workpieces are placed in the chute 2. The driving component drives the push plate 4 to push the multiple workpieces toward one end of the discharge port, so that the workpieces in the chute 2 can be separated from the discharge port one by one and enter the next workstation, realizing automatic loading of the workpieces. Compared with the existing technology of manually transferring the workpieces one by one to the corresponding next workstation, the work efficiency is greatly improved and labor costs are saved.
[0028] In this embodiment, specifically, the mounting base includes a first slider plate 5 and a second slider plate 6 that are arranged vertically and perpendicular to each other, wherein the second slider plate 6 is connected to the first sliding plate of the first slider plate 5, the carrier plate 1 is connected to the second sliding plate of the second slider plate 6, and the length direction of the carrier plate 1 is consistent with the sliding direction of the first sliding plate or the second sliding plate. In this structure, the first slider plate 5 and the second slider plate 6 being perpendicular to each other specifically means that the movement directions of the first sliding plate and the second sliding plate are mutually perpendicular. That is, the structure of the first slider plate 5 and the second slider plate 6 enables the carrier plate 1 to be moved and adjusted along its length and width directions, thereby ensuring that during actual use, the workpiece in the chute 2 can more accurately enter the next workstation, thereby improving the loading accuracy.
[0029] See attached Figure 3 The slider drag plate involved in the above structure is the existing technology, which includes a base and a sliding plate. The corresponding screw drive unit is pre-installed in the base, and a handwheel or motor is connected to one end of the base to drive the screw to rotate, thereby driving the sliding plate to slide horizontally along the corresponding direction.
[0030] In this embodiment, the sliding connection between the slide and the carrier plate 1 involves connecting a linear guide 11 extending along the length of the carrier plate 1 to the lower end of the slide 3. A slider 12 is connected to the lower end of the slide 3, and the slider 12 is slidably mounted on the linear guide 11 to ensure smooth sliding of the slide 3 on the carrier plate 1. Furthermore, in this structure, a support plate 19 is provided on top of the second sliding plate, and the carrier plate 1 is connected to the top of the support plate 19 to elevate the carrier plate 1, ensuring that there is space on the lower end surface of the carrier plate 1 for mounting the linear guide 11 and that the slide 3 does not interfere with the second sliding plate during sliding.
[0031] In addition, see the attached Figure 1The driving assembly involved in this embodiment includes a first pulley 7, a second pulley 8, a pull rope 9 and a counterweight unit 10, wherein the first pulley 7 is connected to the side wall of the carrier plate 1 near the discharge port, the second pulley 8 is connected to the side wall of the other end of the carrier plate 1, and the position of the slide 3 on the carrier plate 1 is located between the two pulleys, one end of the pull rope 9 passes around the second pulley 8 and the first pulley 7 in sequence and is then connected to the slide 3 in reverse, and the counterweight unit 10 is suspended at the other end of the pull rope 9. In this structure, under the action of the counterweight unit 10, the slide 3 always has a tendency to move toward one end of the discharge port, that is, when the workpiece closest to the discharge port in the chute 2 is detached from the discharge port, the slide 3 moves toward one end of the discharge port by a distance of the thickness of the workpiece, and so on. As the workpieces in the chute 2 are detached from the discharge port one by one, the slide 3 drives the push plate 4 to move slowly toward the discharge port until the slide 3 moves to the set static position; the entire process does not require power element driving, and only relies on the action of the counterweight unit 10 to drive the workpieces to automatically enter the next workstation one by one. The structure is simple, the operation is convenient, the loading is stable, and the cost is low; in addition, the counterweight unit 10 can be replaced and adjusted in real time according to the number and specifications of the workpieces to be conveyed, which is very convenient.
[0032] In addition, in the above structure, see the attached Figure 1 Preferably, the chute 2 is a V-shaped groove. The V-shaped structure facilitates the positioning of circular workpieces. The end of the push plate 4 away from the slide 3 extends into the chute 2 to ensure smooth pushing of the workpiece along the chute 2. Specifically, two positioning plates 18 are connected to the top surface of the carrier plate 1. The upper portions of the two positioning plates 18 on opposite sides are provided with inclined surfaces, so that a V-shaped chute 2 is formed between the two positioning plates 18. The two positioning plates 18 can be moved along the width direction of the carrier plate 1 to achieve width adjustment of the chute 2, which is suitable for workpieces of different specifications and improves versatility.
[0033] In addition, in this embodiment, the lower end of the portion of the push plate 4 located in the chute 2 is a circular structure, which facilitates the translation of the circular workpiece.
[0034] On the other hand, see the Figure 4 and 5This embodiment also discloses a turntable grinder, including a frame 13, on which a grinding channel, a feed turntable 14 and a turntable drive motor are provided. The turntable drive motor is used to drive the feed turntable 14 to move in a circular motion, and the feed turntable 14 is used to drive the workpieces to pass through the grinding channel one by one to achieve grinding processing of one end face or two end faces of the workpiece. Specifically, in this embodiment, a plurality of storage holes 15 distributed along its circumference and used to accommodate workpieces are provided on the feed turntable 14, and the aforementioned automatic feeding mechanism is also provided on the frame 13. When the turntable driving motor drives the feed turntable 14 to rotate circumferentially, the counterweight unit 10 drives the push plate 4 to move toward one end of the discharge port, so as to push the workpieces in the chute 2 into the corresponding storage holes 15 one by one; since the feed turntable 14 is rotating, when a storage hole 15 is loaded with a workpiece, the next empty storage hole 15 rotates to the position corresponding to the discharge port, and under the pushing action of the counterweight unit 10, the workpiece in the chute 2 closest to the discharge port continues to be pushed out. The workpieces are continuously moved and fitted into the corresponding storage holes 15, and so on. The workpieces in the chute 2 are continuously moved one by one and fitted into the storage holes 15 on the feed turntable 14, and as the feed turntable 14 rotates, the storage holes 15 containing the workpieces rotate through the grinding channel, and one end or both ends of the workpiece are ground by the grinding disc rotating in the grinding channel, and the ground workpiece continues to rotate with the feed turntable 14, and a push rod mechanism is provided at the corresponding position on the frame 13 for pushing the ground workpiece out of the storage hole 15. The whole process of workpiece feeding and grinding is automated and continuous, and the work efficiency is high.
[0035] More specifically, in order to ensure that the workpiece will not escape from the storage hole 15 before reaching the grinding channel during the rotation of the feed turntable 14, in this embodiment, support frames 16 are connected to the frame 13 and are located on both sides of the feed turntable 14. The two support frames 16 are connected with a baffle plate 17 with an arc structure and concentric with the feed turntable 14. One end of the baffle plate 17 extends to the entrance end of the grinding channel, and the other end extends to a position corresponding to the upper end surface of the slide 2; a positioning channel is formed between the two baffle plates 17, and the feed turntable 14 rotates and slides in the positioning channel. In this structure, the baffle plate 17 not only serves to limit the workpiece in the storage hole 15, but also, the baffle plate 17 close to one end of the loading plate 1 can prevent the workpiece in the chute 2 from moving upward during the rotation of the feed turntable 14. Specifically, the discharge port of the chute 2 corresponds to the center of the storage hole 15 on the feed turntable 14, that is, when the feed turntable 14 rotates to the position of any storage hole 15 and is aligned with the discharge port, the workpiece in the chute 2 can be smoothly moved to the storage hole 15, and Under the action of the counterweight unit 10, the remaining workpieces continue to move toward the discharge port end of the chute 2; in this structure, the discharge port end of the chute 2 slides with a side surface of the feed turntable 14, and when the workpiece closest to the discharge port end in the chute 2 enters the storage hole 15, the adjacent subsequent workpiece is just blocked by the baffle plate 17 to limit the position, so when the feed turntable 14 rotates, the subsequent workpiece will not be driven to move upward, ensuring that the workpieces are continuously and smoothly assembled one by one into the storage hole 15 of the feed turntable 14.
[0036] In the description of this application, the description with reference to the terms "this embodiment", "some embodiments", etc. means that the specific features, mechanisms, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, mechanisms, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples, unless they are mutually inconsistent.
[0037] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application.
