Description

Technical Field

[0001] This utility model relates to the field of magnetic polishing technology, specifically a deburring device for sheet metal parts. Background Technology

[0002] A magnetic stirring polishing machine is a precision machining device that uses a magnetic field to drive magnetic abrasives. Through the friction and cutting action between the abrasives and the workpiece surface, it achieves functions such as polishing, deburring, and cleaning. Combining magnetic drive and stirring technology, it can handle parts with various complex structures, and is especially suitable for delicate areas that are difficult to reach with traditional polishing methods. The magnetic polishing machine accelerates the abrasives, using their impact to clean surface contaminants and achieve a smooth surface.

[0003] In existing technologies, when using a magnetic stirring polishing machine, the polishing parts, abrasive, and polishing fluid are directly placed inside the stirring tank. The abrasive rotates at high speed in a magnetic field environment, and the polishing parts rotate with the abrasive. This reduces the relative speed between the polishing parts and the abrasive, resulting in a decrease in the number of impacts of the abrasive on the polishing parts per unit time. This directly affects the polishing efficiency and prolongs the polishing time. Furthermore, the application of traditional magnetic stirring polishing machines is limited to performing the same polishing precision on the same batch at a time, and cannot perform differentiated polishing treatments. Utility Model Content

[0004] The purpose of this utility model is to provide a deburring device for sheet metal parts. First, the polishing parts are stored in a mesh frame, and then connected to a protective cover by a connector to prevent the polishing parts from rotating with the abrasive. This reduces the relative speed between the polishing parts and the abrasive. Even when the abrasive rotates at high speed, the speed of the abrasive relative to the polishing parts can be maintained. At the same time, the speed of the abrasive varies depending on the distance of its rotation from the center in the fixed cylinder, thereby performing differentiated polishing treatment on the polishing parts in different positions within the mesh frame, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deburring device for sheet metal parts, comprising:

[0027] 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.

[0028] This utility model provides, for example Figures 1-5The sheet metal deburring device shown includes:

[0029] Magnetic stirring polisher body 1;

[0030] The main body 1 of the magnetic stirring polisher includes a base 101 and a fixed cylinder 102 fixed to the top of the base 101;

[0031] The top of the fixed cylinder 102 is snapped with a protective cover 2. The bottom of the protective cover 2 is provided with multiple sets of rotatable mesh frames 3 for storing polished parts, and the mesh frames 3 are distributed in multiple rings from the inside to the outside.

[0032] The protective cover 2 is equipped with a drive component 4 that drives the inner and outer mesh frames 3 at different speeds. The mesh frame 3 and the drive component 4 are connected by a connector 5.

[0033] A gantry frame 6 is fixed to the top of the base 101, and a lifting assembly 7 for lifting the protective cover 2 is provided on the gantry frame 6.

[0034] By storing the polished parts in the mesh frame 3, not only can the stability of the polished parts' position be ensured, preventing them from colliding with each other and causing damage, but the fixed position of the polished parts can also prevent the polished parts from rotating with the abrasive cylinder, which would reduce the relative speed between the polished parts and the abrasive and reduce the polishing efficiency of the abrasive. At the same time, by utilizing the different speeds of the abrasive at different distances from the center within the fixed cylinder 102, different polishing treatments can be performed on polished parts at different positions, making it convenient to process different polished parts simultaneously and achieve polishing treatments with different polishing effects.

[0035] Among them, such as Figure 3 As shown:

[0036] The drive assembly 4 includes a drive motor 41 fixed at the center of the top of the protective cover 2. The output shaft of the drive motor 41 passes through the interior of the protective cover 2 and is fixed with two sets of drive gears 42 of different radii. The bottom of the protective cover 2 is rotatably connected to a drive shaft 43 via a bearing. The top of the drive shaft 43 passes through the interior of the protective cover 2 and is fixed with a driven gear 44 that meshes with the drive gear 42. The drive motor 41 drives the drive gear 42 to rotate, and then the drive gear 42 drives the driven gear 44 to rotate. The driven gear 44 uses the drive shaft 43 and the connecting piece 5 to drive the mesh frame 3 to rotate, adjusting the angle of the polishing part, so as to achieve friction polishing of the abrasive material from all directions and multiple angles.

[0037] Furthermore, such as Figure 4 As shown:

[0038] The connector 5 includes a connecting rod 51 and a sleeve 52. One end of the connecting rod 51 is fixed to the top of the mesh frame 3, and the other end of the connecting rod 51 extends into the inner cavity of the sleeve 52. The end of the sleeve 52 away from the connecting rod 51 is detachably connected to the drive shaft 43. By setting the structure of the connector 5, it is convenient to adjust the height of the mesh frame 3, avoid the mesh frame 3 from contacting the bottom of the fixed cylinder 102, and ensure the smooth flow of abrasive.

[0039] Preferred, such as Figure 4 As shown:

[0040] The bottom of the drive shaft 43 is provided with a slot, and the top of the sleeve 52 is engaged in the slot. The lower ends of the outer walls of the drive shaft 43 and the sleeve 52 are threaded with limit bolts 8. The limit bolts 8 pass through the slot and the inner cavity of the sleeve 52 and abut against the connecting rod 51 and the sleeve 52 respectively. The sleeve 52 is connected to the drive shaft 43 through the slot. Then, the limit bolts 8 are used to lock the connecting rod 51, the sleeve 52 and the drive shaft 43 to maintain the stability of the mesh frame 3.

[0041] It is worth noting that, such as Figure 2 As shown:

[0042] The lifting assembly 7 includes a take-up shaft 71 rotatably connected to the upper inner side of the gantry frame 6 via bearings. Two sets of take-up drums 72 are fixed on the take-up shaft 71. A take-up motor 73 is fixed on the outer side of the gantry frame 6. The output shaft of the take-up motor 73 is fixedly connected to one end of the take-up shaft 71. A traction rope 74 is wound around the outer side of the take-up drum 72. One end of the traction rope 74 extends downward and is fixed with a hook 75. The take-up motor 73 drives the take-up shaft 71 to rotate. Then, the take-up shaft 71 uses the take-up drum 72 to wind up and unwind the two sets of traction ropes 74, which can adjust the height of the protective cover 2.

[0043] In a further preferred embodiment, such as Figure 2 and Figure 5 As shown:

[0044] The protective cover 2 has pins fixed at both ends of its top, and hanging rings 9 are movably provided on the pins. Hooks 75 are used in conjunction with hanging rings 9. By installing hanging rings 9 on the top of the protective cover 2, it is convenient to connect the protective cover 2 using hooks 75.

[0045] In addition, such as Figure 1 As shown:

[0046] A controller 10 is installed on the side wall of the gantry frame 6. The controller 10 is electrically connected to the magnetic stirring polishing machine body 1, the drive motor 41 and the winding motor 73 respectively. The controller 10 adopts a PLC controller 10, which facilitates the magnetic stirring polishing machine body 1 to operate automatically according to the set program, and is also used to control the drive motor 41 and the winding motor 73.

[0047] In this embodiment, as Figure 1 and Figure 5 As shown:

[0048] The top of the protective cover 2 is fixed with a lifting handle 11, and the lifting handle 11 and the hanging ring 9 are arranged in a cross-shaped symmetrical arrangement on the top of the protective cover 2. The lifting handle 11 makes it convenient to manually align the protective cover 2 and install the protective cover 2 on the top of the fixed cylinder 102.

[0049] In practical use, open the mesh frame 3, place the polishing part inside the mesh frame 3, then close the mesh frame 3. Simultaneously, align the top of the sleeve 52 with the drive shaft 43 and lock it using the limit bolt 8. Adjust the position of the connecting rod 51 within the sleeve 52 and lock it using the limit bolt 8. Then, introduce the abrasive and clean water into the fixed cylinder 102. Polishing liquid can also be poured into the fixed cylinder 102. Then, control the winding motor 73 via the controller 10. The winding motor 73 drives the winding shaft 71, which, in conjunction with the winding drum 72, releases the traction rope 74, thus protecting the... The cover 2 moves downwards and then covers the top of the fixed cylinder 102. Then, the controller 10 controls the magnetic stirring polishing machine body 1 to rotate and drive the abrasive to rotate. The abrasive moves centrifugally inside the fixed cylinder 102 and rubs and polishes the polishing parts inside the mesh frame 3 through high-speed movement. At the same time, the controller 10 starts the drive motor 41, which drives two sets of drive gears 42 to rotate. The drive gears 42 drive the driven gears 44 to rotate. The driven gears 44 drive the drive shaft 43 and the connecting piece 5 to rotate the mesh frame 3 and adjust the angle of the polishing parts.

[0050] The electromagnetic coil or permanent magnet inside the base 101 generates a magnetic field, which attracts magnetic abrasives (such as steel needles, steel balls, ceramic particles, etc.), forming an effect similar to an "abrasive brush".

[0051] When the magnetic field rotates or vibrates, the abrasive moves around the workpiece at high frequency under the action of the magnetic force, and removes burrs, oxide layers or stains from the surface of the workpiece through friction.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
