Description

Technical Field

[0001] The present application relates to grinding technology, and particularly to a magnetic grinding machine. Background Art

[0002] The current magnetic grinding machine includes a grinding barrel, a support plate, a magnetic disk, a main motor tray, a main motor and a chassis. Among them, the main motor tray, the main motor and the chassis are fixedly connected, that is, the positions of the three are fixed. During operation, the main motor drives the magnetic disk to rotate, and the magnetic force generated by the magnetic steel on the magnetic disk drives the magnetic needles in the grinding barrel to move through the support plate to grind the workpiece.

[0003] Since the running track of the steel needles in the grinding barrel is circular and the central part of the grinding area of the grinding barrel is hollow, the area of the grinding area is reduced, which reduces the grinding efficiency. In addition, for workpieces with a large area, the hollow part in the grinding area cannot be ground, affecting the grinding quality of the workpiece. Summary of the Utility Model

[0004] In order to overcome the above defects, the present application provides a magnetic grinding machine in which the center of the grinding area of the grinding barrel does not present a hollow shape, thereby increasing the effective area of the grinding area of the grinding barrel and the grinding efficiency of the grinding barrel.

[0005] The technical solution adopted by the present application to solve its technical problems is:

[0006] A magnetic grinding machine includes a box body, a main motor, a tray, a magnetic disk and an annular drive mechanism installed in the box body. A support plate is fixedly installed on the box body, and a grinding barrel is placed on the support plate. The main motor is fixedly installed on the tray, the magnetic disk is placed on the tray, the main motor is connected to the magnetic disk, and the main motor can drive the magnetic disk to rotate relative to the tray. The annular drive mechanism is connected to the tray, and the annular drive mechanism can drive the tray and the magnetic disk to perform an annular movement.

[0007] Optionally, the annular drive mechanism includes a rotary motor, a fixed seat and a movable crank. The rotary motor is fixedly installed in the box body, the movable crank is rotatably installed on the fixed seat, the first end of the movable crank is fixedly connected to the rotary motor, and the second end of the movable crank is fixedly connected to the tray.

[0008] Optionally, the fixed seat is fixedly installed in the box body, the movable crank includes a first rotating shaft and a second rotating shaft arranged in parallel, the first rotating shaft is fixedly connected to the rotary motor, and the second rotating shaft is fixedly connected to the tray.

[0009] Optionally, a fixed seat is provided on each side of the main motor. Two movable cranks are provided on each fixed seat. The four movable cranks are fixedly connected to the four corner ends of the tray, and the rotating motor is connected to any one of the movable cranks.

[0010] Optionally, the structure of the grinding barrel includes a polyhedron structure.

[0011] Optionally, the structure of the grinding barrel includes a prism structure.

[0012] Optionally, the grinding barrel includes a bottom plate and a plurality of side plates connected to the bottom plate. The plurality of side plates are sequentially connected to form a closed annular structure. The side plates are vertically arranged on the bottom plate, and the number of the side plates is 4 - 12.

[0013] Optionally, one, two or more disks are placed on the tray, and each disk is connected to a main motor.

[0014] The beneficial effects of the present application are as follows: In the present application, while the disk rotates on its own under the action of the main motor, the annular drive mechanism also drives the disk to perform an annular motion. That is, the magnetic needle in the grinding barrel not only moves in the circumferential direction but also moves in the radial direction under the action of the magnetic steel. Therefore, the center of the grinding area of the grinding barrel will not present a hollow shape, that is, all grinding areas are effective areas, thereby increasing the effective area of the grinding area of the grinding barrel and the grinding efficiency of the grinding barrel. At the same time, the workpieces in the grinding barrel can be subjected to multi-directional grinding forces, improving the grinding quality of the workpieces. Description of the Drawings

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the embodiments of this application. Obviously, the described embodiments of this application are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the following drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the objects so used can be interchanged under appropriate circumstances, so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0026] For the sake of description, spatial relative terms such as "above...", "above...", "on the upper surface of...", "above" and the like can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation shown in the figure of the device.

[0027] Embodiment: As Figure 1-8As shown in the figure, a magnetic abrasive machine includes a box body 10, a main motor 20, a tray 30, a magnetic disk 40, and an annular drive mechanism 50 installed inside the box body 10. A support plate 11 is fixedly installed on the box body 10, and a grinding barrel 12 is placed on the support plate 11. Magnetic needles, workpieces, and grinding fluid are placed inside the grinding barrel 12. The support plate 11 covers the box body 10, enclosing the main motor 20, the tray 30, the magnetic disk 40, and the annular drive mechanism 50 inside the box body 10. The main motor 20 is fixedly installed on the tray 30, and the magnetic disk 40 is placed on the tray 30. The magnetic disk 40 has a magnet that generates magnetic force. The main motor 20 is connected to the magnetic disk 40, and the main motor 20 can drive the magnetic disk 40 to rotate relative to the tray 30. The annular drive mechanism 50 is connected to the tray 30, and the annular drive mechanism 50 can drive the tray 30 and the magnetic disk 40 to perform circular motion. The main motor 20 also runs synchronously, and the number of main motors 20 can be designed arbitrarily according to needs. The so-called circular motion means that the tray 30 performs a cyclic operation in the directions of forward - left - backward - right inside the box body 10, and the magnetic disk 40 runs synchronously with the tray 30. In this application, while the magnetic disk 40 rotates under the action of the main motor 20, the annular drive mechanism 50 also drives the magnetic disk 40 to perform circular motion. That is, the magnetic needles in the grinding barrel 12 not only perform circumferential motion but also perform radial motion under the action of the magnet. Therefore, the center of the grinding area of the grinding barrel does not present a hollow shape, that is, all grinding areas are effective areas, thereby increasing the effective area of the grinding area of the grinding barrel and the grinding efficiency of the grinding barrel; at the same time, the workpieces in the grinding barrel can be subjected to multi-directional grinding forces, improving the grinding quality of the workpieces.

[0028] As Figure 2-4As shown in the figure, the ring drive mechanism 50 includes a rotary motor 51, a fixed seat 52 and a movable crank 53. The rotary motor 51 is fixedly installed in the box body 10. The movable crank 53 is rotatably installed on the fixed seat 52. The first end of the movable crank 53 is fixedly connected to the rotary motor 51, and the second end of the movable crank 53 is fixedly connected to the tray 30. When the rotary motor 51 rotates, it drives the movable crank 53 to rotate. The movable crank 53 drives the tray 30 to perform a circular motion in the front, back, left and right directions with the rotation axis of the rotary motor 51 as the center. The magnetic disk 40 located on the tray 30 runs synchronously. The magnetic steel on the magnetic disk 40 drives the steel needles in the grinding barrel 12 to move in the radial direction, thus breaking the tradition that the steel needles only move in the circumferential direction. On the one hand, the steel needles can generate multi-directional grinding forces on the workpiece, improving the grinding effect and efficiency of the workpiece. On the other hand, it makes the grinding area of the grinding barrel not generate hollow areas that cannot be ground, increasing the effective area of the grinding area of the grinding barrel, and is suitable for grinding large-volume workpieces. As long as the workpiece can be placed in the grinding barrel, it can be ground, and there will be no situation where some areas of the workpiece are not ground.

[0029] As Figure 3-5 shown in the figure, the fixed seat 52 is fixedly installed in the box body 10. The movable crank 53 includes a first rotating shaft 54 and a second rotating shaft 55 arranged in parallel. The first rotating shaft 54 is fixedly connected to the rotary motor 51, and the second rotating shaft 55 is fixedly connected to the tray 30. By using the two parallelly arranged first rotating shaft 54 and second rotating shaft 55, the tray 30 can be made to move along a circular trajectory centered on the first rotating shaft 54, expanding the movement range of the tray 30 and the magnetic disk 40, and further improving the grinding effect of the steel needles.

[0030] As Figure 3-5 shown in the figure, on both sides of the main motor 20, there is one fixed seat 52 respectively. Each fixed seat 52 is provided with two movable cranks 53. The four movable cranks 53 are fixedly connected to the four corner ends of the tray 30. The rotary motor 51 is connected to any one of the movable cranks 53. Optionally, the tray 30 has a square structure and the magnetic disk 40 has a disc-shaped structure. Using the movable cranks 53 at the four corner ends to support the tray 30 and the magnetic disk 40 can improve the stability of the tray 30 and the magnetic disk 40 during operation.

[0031] As Figure 6-8 shown in the figure, the structure of the grinding barrel 12 includes a polyhedron structure. Designing the grinding barrel 12 as a polyhedron structure instead of the traditional cylindrical structure, with a certain included angle formed on the side wall of the grinding barrel 12, can effectively reduce the rolling of the workpiece and further improve the grinding ability of the grinding machine.

[0032] Optionally, the structure of the grinding barrel 12 includes a prismatic structure. That is, the upper bottom surface and the lower bottom surface of the grinding barrel 12 are arranged in parallel.

[0033] As Figure 6-8 shown, the grinding barrel 12 includes a bottom plate 13 and a plurality of side plates 14 connected to the bottom plate 13. The plurality of side plates 14 are sequentially connected to form a closed annular structure. The side plates 14 are vertically arranged on the bottom plate 13, and the number of the side plates 14 is 4 - 12. The upper end of the grinding barrel 12 is in an open state, the inside is in a hollow state, and the lower end is closed by the bottom plate 13. The upper surface of the bottom plate 13 is the grinding area. The plurality of side plates 14 enclose a prism. In an embodiment, the grinding barrel 12 is provided with 8 side plates 14 of the same size and structure. An angle greater than 90° is formed between two adjacent side plates 14 to prevent the workpiece from rolling on the bottom plate 13. Of course, the number of side plates 14 of the grinding barrel 12 can also be 5, 6, 7, etc. to meet the actual grinding requirements.

[0034] One, two or more of the magnetic disks 40 are placed on the tray 30, and each magnetic disk 40 is connected to the main motor 20. That is, the number of the magnetic disks 40 and the main motor 20 can be arbitrarily set according to the size of the grinding barrel 12 to improve the grinding efficiency.

[0035] The operation process of this application includes the following steps: As Figure 1 shown, the grinding barrel 12 is placed at a preset position on the support plate 11, magnetic needles, workpieces, grinding fluid, etc. are put into the grinding barrel 12. At the same time, the main motor 20 and the rotary motor 51 are turned on. The main motor 20 drives the magnetic disk 40 to rotate, and the rotary motor 51 drives the magnetic disk 40 to perform a circular motion around the rotation axis of the rotary motor 51. That is, the magnetic needles in the grinding barrel 12 move in the circumferential direction and also move in the radial direction under the action of the magnetic steel to complete the grinding work of the workpiece.

[0036] It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of this application patent shall be subject to the appended claims.
