Description

Technical Field

[0001] This application belongs to the technical field of metal surface treatment equipment, and particularly relates to a magnetic grinding machine for metal surface treatment. Background Technology

[0002] In the field of metal processing, surface treatment is a crucial step in improving the quality and performance of metal products, and magnetic abrasive grinding machines occupy an important position among various surface treatment equipment due to their unique working principle and significant advantages. Their main principle is to use magnetic force to drive abrasive media, such as stainless steel needles, to perform high-frequency friction and grinding on the workpiece surface. Under the influence of the magnetic field, these abrasive media can flexibly conform to the complex shape of the workpiece, penetrating even the smallest gaps and pores, achieving comprehensive and thorough grinding treatment.

[0003] Currently, most mainstream magnetic grinders use an equidistant, symmetrical installation design for their tray magnets. The magnets are evenly distributed radially along the center of the tray, and the tray drives the magnets to rotate on a fixed axis below the material trough, thus moving the stainless steel needles. While this design simplifies the processing and assembly process, in actual operation, dead corners can easily form in the middle of the material trough, reducing the grinding effect of the magnetic grinder. Utility Model Content

[0004] The purpose of this application is to provide a magnetic grinding machine for metal surface treatment, which aims to solve the problem that existing magnetic grinding machines easily form dead corners in the middle of the material tank, reducing the grinding effect of the magnetic grinding machine.

[0005] This application embodiment is implemented as follows: a magnetic polishing machine for metal surface treatment includes: A frame is provided with a linear slide groove, a slider is slidably arranged on the linear slide groove, and the frame is provided with a material trough for holding workpieces and grinding media; A waist-shaped component is rotatably mounted on the frame. The pivot of the waist-shaped component is eccentrically set. The waist-shaped component is provided with a waist-shaped sliding groove and a waist-shaped tooth extending along the waist-shaped sliding groove. A swing wheel is rotatably mounted on the slider. The swing wheel is provided with a limiting member that extends to the waist-shaped groove and can slide along the waist-shaped groove. The outer circumferential surface of the swing wheel is provided with gear teeth that mesh with the waist-shaped toothed portion. A magnetic component is provided on the swing wheel and located below the material trough. The waist-shaped component drives the swing wheel to rotate and, through the cooperation of the waist-shaped slide and the limiting component, drives the swing wheel to swing back and forth.

[0006] In some preferred embodiments of this application, the magnetic component includes a sliding frame slidably disposed on the frame, a first gear fixedly disposed on the sliding frame, a rotating frame rotatably disposed on the sliding frame, the rotating shaft of the rotating frame being coaxially disposed with the axis of the first gear and coaxially fixedly connected to the swing wheel, a second gear rotatably disposed on the rotating frame, the second gear meshing with the first gear, a tray fixedly disposed on the second gear, and at least two magnets disposed on the tray.

[0007] In some preferred embodiments of this application, a third gear is rotatably mounted on the rotating frame. The third gear is symmetrically arranged with respect to the second gear and meshes with the first gear. Another tray is fixedly mounted on the third gear, and at least two magnets are mounted on the tray.

[0008] In some preferred embodiments of this application, the magnet includes a first set of magnets near the center of rotation of the tray and a second set of magnets away from the center of rotation of the tray.

[0009] In some preferred embodiments of this application, the first group of magnets includes two first magnets arranged symmetrically at the center, and the second group of magnets includes two second magnets arranged symmetrically at the center.

[0010] In some preferred embodiments of this application, the trough is a waist-shaped trough.

[0011] In some preferred embodiments of this application, the waist-shaped member is provided with a balancing hole, which is used to balance the eccentric mass of the waist-shaped member.

[0012] This application provides a magnetic polishing machine for metal surface treatment. When the waist-shaped part rotates, the meshing transmission between the waist-shaped teeth and the teeth of the swing wheel drives the swing wheel to rotate, which in turn drives the magnetic component to rotate, causing the polishing media in the trough to move and polish the workpiece. In addition, the waist-shaped part rotates eccentrically on the frame, and through the cooperation of the limiting part and the waist-shaped slide, it drives the swing wheel to swing back and forth. In this way, the magnetic component will not have a fixed dead point, improving the uniformity and polishing effect. Attached Figure Description

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0016] The specific implementation of this application will be described in detail below with reference to specific embodiments.

[0017] like Figures 1 to 4 As shown in the figure, this application provides a magnetic polishing machine for metal surface treatment, including: a frame 100, a waist-shaped component 200, a swing wheel 300, and a magnetic assembly 400.

[0018] like Figure 4 As shown, the frame 100 is provided with a linear slide groove 111, and a slider 112 is slidably disposed on the linear slide groove 111, such as... Figure 1 As shown, the frame 100 is provided with a material tank 130 for holding the workpiece and the grinding medium. In this embodiment, the workpiece and the grinding medium are placed together in the material tank 130. The grinding medium can be a stainless steel needle. The magnetic component 400 drives the stainless steel needle to move and impact the workpiece to perform surface treatment on the workpiece to remove burrs or oxide layers.

[0019] like Figure 4 As shown, the waist-shaped component 200 is rotatably mounted on the frame 100. The axis of rotation of the waist-shaped component 200 is eccentrically positioned. The waist-shaped component 200 is provided with a waist-shaped groove 210 and a waist-shaped toothed portion 220 extending along the waist-shaped groove 210. It should be noted that the waist shape described in this application is a closed shape formed by two parallel and equal-length straight segments and two semi-circular arc segments of equal radius smoothly transitioning and connecting. In some embodiments, the axis of rotation of the waist-shaped component 200 is located at the center of one of the semi-circular arcs, and the waist-shaped toothed portion 220 is located inside the waist-shaped groove 210. A drive motor 120 is provided on the frame 100, and the output shaft of the drive motor 120 is coaxially fixedly connected to the axis of rotation of the waist-shaped component 200.

[0020] like Figure 1 and Figure 4 As shown, the swing wheel 300 is rotatably mounted on the slider 112. The swing wheel 300 is provided with a limiting member, which extends to the waist-shaped slide groove 210 and can slide along the waist-shaped slide groove 210. The outer peripheral surface of the swing wheel 300 is provided with gear teeth that mesh with the waist-shaped toothed portion 220. like Figure 1 and Figure 2 As shown, the magnetic component 400 is disposed on the swing wheel 300 and located below the material trough 130. The waist-shaped component 200 drives the swing wheel 300 to rotate and drives the swing wheel 300 to swing back and forth through the cooperation of the waist-shaped slide groove 210 and the limiting component.

[0021] In this embodiment, when the waist-shaped component 200 rotates, the meshing transmission between the waist-shaped teeth 220 and the teeth of the swing wheel 300 drives the swing wheel 300 to rotate, which in turn drives the magnetic component 400 to rotate, causing the grinding media in the material tank 130 to move and grind the workpiece. In addition, the waist-shaped component 200 rotates eccentrically on the frame 100, and through the cooperation of the limiting component and the waist-shaped slide 210, it drives the swing wheel 300 to swing back and forth. In this way, the magnetic component 400 will not have a fixed dead point, improving the uniformity and grinding effect of grinding.

[0022] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the magnetic component 400 includes a sliding frame 410, which is slidably mounted on the frame 100. A first gear 411 is fixedly mounted on the sliding frame 410. A rotating frame 420 is rotatably mounted on the sliding frame 410. The rotating shaft of the rotating frame 420 is coaxially arranged with the axis of the first gear 411 and coaxially fixedly connected to the swing wheel 300. A second gear 430 is rotatably mounted on the rotating frame 420. The second gear 430 meshes with the first gear 411. A tray 450 is fixedly mounted on the second gear 430. At least two magnets are disposed on the tray 450.

[0023] In this embodiment, the swing wheel 300 drives the rotating frame 420 to rotate, and the rotating frame 420 drives the second gear 430 to revolve around the first gear 411. Since the second gear 430 and the first gear 411 mesh, the second gear 430 rotates on its own axis while revolving around the first gear. In this way, the tray 450 and the magnet can rotate on their own axis and revolve around the first gear, thereby further improving the uniformity and efficiency of grinding.

[0024] like Figure 4As shown, in some embodiments of this application, a third gear 440 is rotatably mounted on the rotating frame 420. The third gear 440 is axially symmetrically arranged with the second gear 430, and meshes with the first gear 411. Another tray 450 is fixedly mounted on the third gear 440, and at least two magnets are mounted on the tray 450. In this embodiment, the axially symmetrical arrangement of the third gear 440 and the second gear 430 enables the rotating frame 420 to be subjected to force balance.

[0025] like Figure 4 As shown, in some embodiments of this application, the magnet includes a first set of magnets near the rotation center of the tray 450 and a second set of magnets away from the rotation center of the tray 450. This ensures that the magnets cover a larger area during movement, guaranteeing uniform grinding.

[0026] In some embodiments of this application, such as Figure 4 As shown, the first set of magnets includes two first magnets 461, which are arranged symmetrically at the center, and the second set of magnets includes two second magnets 462, which are also arranged symmetrically at the center. This ensures that the force is evenly distributed when the tray 450 rotates.

[0027] In some embodiments of this application, the material trough 130 is a waist-shaped material trough. This allows it to accommodate some workpieces with longer lengths, and the reciprocating oscillation of the magnetic component 400 ensures that all parts of the waist-shaped material trough receive magnetic force.

[0028] In some embodiments of this application, the waist-shaped member 200 is provided with a balancing hole 230, which is used to balance the eccentric mass of the waist-shaped member 200. In this embodiment, the balancing hole 230 reduces the mass of the eccentric part, reduces the centrifugal force when the waist-shaped member 200 rotates, and reduces the vibration of the magnetic grinder.

[0029] This application provides a magnetic polishing machine for metal surface treatment. When the waist-shaped component 200 rotates, the meshing transmission between the waist-shaped teeth 220 and the teeth of the swing wheel 300 drives the swing wheel 300 to rotate, which in turn drives the magnetic component 400 to rotate, causing the polishing media in the material tank 130 to move and polish the workpiece. In addition, the waist-shaped component 200 rotates eccentrically on the frame 100. Through the cooperation of the limiting component and the waist-shaped slide 210, the swing wheel 300 is driven to oscillate back and forth. In this way, the magnetic component 400 will not have a fixed dead point, improving the uniformity and polishing effect.

[0030] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
