Description

Technical Field

[0001] This utility model relates to the field of sanding machine technology, specifically to a mechanical swing structure for a sanding machine. Background Technology

[0002] A sander, also called a polishing machine, is an electric tool that uses sandpaper or abrasive wheels to sand and polish the surfaces of materials such as wood, metal, and plastic. It is widely used in sanding operations in various fields.

[0003] However, in actual use, professionals in related fields have found that after sanding the surface of materials such as wood, repetitive and regular sanding marks are formed on the surface, creating stripes that are difficult to remove and affecting the surface smoothness. At the same time, there is a lack of structure to absorb the generated debris during the sanding process, which leads to debris pollution of the environment and even damage to the structure of the device. Therefore, a mechanical oscillating structure for sanders is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a mechanical swing structure for a sander to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mechanical swing structure for a sander, comprising a housing, wherein a first opening is provided at the middle position of the upper surface of the housing, and a second opening is provided behind the first opening on the upper surface of the housing, wherein a sanding component is inserted inside the first opening.

[0006] The shell is equipped with a swing mechanism inside, a moving mechanism is provided behind the swing mechanism, a mounting rod is provided between the swing mechanism and the moving mechanism, and a dust suction mechanism is provided above the moving mechanism.

[0007] A motor housing is mounted on the rear surface of the outer casing, and the output end of the motor inside the motor housing passes through the outer casing and is connected to the moving mechanism.

[0008] Preferably, the swing mechanism includes a first connecting plate, a first saw tooth, and a first half gear. The first connecting plate is located inside the outer shell. Multiple first saw teeth are evenly spaced on the inner walls of the left and right ends of the first connecting plate. The first half gear is located in the middle of the inner part of the first connecting plate.

[0009] Preferably, connecting rods are connected to both the left and right ends of the first connecting plate, and connecting rings are connected to the other ends of the multiple connecting rods. Guide rods are inserted inside the multiple connecting rings, and the upper and lower ends of the guide rods are fixedly connected to the inner wall of the outer shell.

[0010] Preferably, the moving mechanism includes a second connecting plate, a second saw tooth, and a second half gear. The second connecting plate is located directly behind the first connecting plate. Multiple second saw teeth are evenly spaced on the inner walls of the upper and lower ends of the second connecting plate. A second half gear is located in the middle of the inner part of the second connecting plate.

[0011] Preferably, a support rod is connected to the lower surface of the second connecting plate, and the bottom end of the support rod is movably connected to the bottom inner wall of the outer casing, and a base plate is connected to the upper surface of the second connecting plate.

[0012] Preferably, the dust collection mechanism includes a collection box, a connecting pipe, and a mounting plate. The collection box is connected to the upper surface of the base plate, and the upper surface of the collection box is connected to both the left and right ends by connecting pipes, with a mounting plate provided on the top of the connecting pipes.

[0013] Preferably, the front and rear ends of the mounting rod are connected to the first half gear and the second half gear, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This sander uses a mechanical oscillating structure. The rotation of the first half gear allows the first connecting plate to move up and down repeatedly, thereby causing the sanding part to oscillate up and down continuously, avoiding the formation of repetitive and regular scratches on the wood.

[0016] 2. This sander uses a mechanical swing structure. Under the action of the mounting rod, the first half gear and the second half gear can rotate synchronously, so that the swing mechanism and the moving mechanism work synchronously. Thus, when the sanded part swings up and down, the dust collection mechanism moves left and right synchronously, effectively collecting debris from different positions on the outer surface.

[0025] Example 1

[0026] like Figures 1 to 5 As shown, this embodiment of a mechanical swing structure for a sander includes a housing 1. A first opening 2 is provided in the middle of the upper surface of the housing 1, and a second opening 3 is also provided in the upper surface of the housing 1 behind the first opening 2. A sanding part 4 is inserted inside the first opening 2. The diameter of the first opening 2 is larger than the diameter of the sanding part 4 to ensure that the sanding part 4 can swing up and down normally.

[0027] The interior of the outer casing 1 is equipped with a swing mechanism 5, which allows the abrasive part 4 to swing up and down, thereby avoiding the formation of repetitive and regular abrasion marks on the wood during sanding. A moving mechanism 10 is provided behind the swing mechanism 5, and a mounting rod 14 is provided between the swing mechanism 5 and the moving mechanism 10. A dust collection mechanism 12 is provided above the moving mechanism 10. The moving mechanism 10 can drive the dust collection mechanism 12 to move synchronously when the abrasive part 4 swings up and down, so as to collect the debris avoided by the outer casing 1. The top of the dust collection mechanism 12 penetrates the outer casing 1 through the second opening 3 to perform dust collection. The mounting rod 14 enables the swing mechanism 5 and the moving mechanism 10 to work synchronously.

[0028] A motor housing 13 is mounted on the rear surface of the outer casing 1, and the output end of the motor inside the motor housing 13 passes through the outer casing 1 and is connected to the moving mechanism 10. The motor inside the motor housing 13 controls the swing mechanism 5 and the moving mechanism 10 to work.

[0029] Furthermore, the swing mechanism 5 includes a first connecting plate 501, a first sawtooth 502, and a first half gear 503. The first connecting plate 501 is located inside the outer casing 1. Multiple first sawtooths 502 are evenly spaced on the inner walls of the left and right ends of the first connecting plate 501. A first half gear 503 is located in the middle of the inner part of the first connecting plate 501. The first half gear 503 is a gear with only half of the surface sawtooths. When it rotates, it will drive the first connecting plate 501 to move up and down reciprocally through the first sawtooth 502, thereby causing the abrasive part 4 to swing up and down.

[0030] Furthermore, connecting rods 6 are connected to both the left and right ends of the first connecting plate 501, and connecting rings 7 are connected to the other ends of the multiple connecting rods 6. Guide rods 8 are inserted inside the multiple connecting rings 7, and the upper and lower ends of the guide rods 8 are fixedly connected to the inner wall of the outer shell 1. The first connecting plate 501 can move up and down stably through the connecting rods 6, connecting rings 7 and guide rods 8. At the same time, magnets are set between the connecting rings 7 and guide rods 8, and it is ensured that the gravity of the structure such as the frosted part 4 is less than the magnetic force to prevent the first connecting plate 501 from automatically descending due to gravity.

[0031] Furthermore, the moving mechanism 10 includes a second connecting plate 1001, a second sawtooth 1002, and a second half gear 1003. The second connecting plate 1001 is located directly behind the first connecting plate 501. Multiple second sawtooths 1002 are evenly spaced on the inner walls of the upper and lower ends of the second connecting plate 1001. The second half gear 1003 is located in the middle of the interior of the second connecting plate 1001. The second half gear 1003 has the same structure as the first half gear 503. When it rotates, it will drive the second connecting plate 1001 to move back and forth left and right.

[0032] Furthermore, a support rod 9 is connected to the lower surface of the second connecting plate 1001, and the bottom end of the support rod 9 is movably connected to the bottom inner wall of the outer casing 1. A base plate 11 is connected to the upper surface of the second connecting plate 1001, and the second connecting plate 1001 is supported by the support rod 9.

[0033] Furthermore, the vacuuming mechanism 12 includes a collection box 1201, a connecting pipe 1202, and a mounting plate 1203. The collection box 1201 is connected to the upper surface of the base plate 11. The connecting pipes 1202 are connected to both the left and right ends of the upper surface of the collection box 1201, and the mounting plate 1203 is provided on the top of the connecting pipes 1202. The collection box 1201 is pre-installed with necessary parts for suction. The specific structure is analogous to a vacuum cleaner. By performing suction, the connecting pipe 1202 with its top bend sucks away the debris on the surface of the outer shell 1.

[0034] Furthermore, the front and rear ends of the mounting rod 14 are connected to the first half gear 503 and the second half gear 1003 respectively, so that the first half gear 503 and the second half gear 1003 can rotate synchronously through the mounting rod 14.

[0035] The usage method of this embodiment is as follows: start the motor to control the first half gear 503 and the second half gear 1003 to rotate synchronously. At this time, the first connecting plate 501 and the second connecting plate 1001 will move up and down and left and right respectively, thereby driving the abrasive part 4 to swing up and down, and at the same time causing the dust collection mechanism 12 to move left and right. The abrasive part 4 swings to perform stable sanding on the wood, and the dust collection mechanism 12 moves left and right to collect the debris distributed at different positions on the surface of the outer shell 1.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
