Description

Technical Field

[0001] This application relates to the field of filing technology, and in particular to a filing and deburring tooling for dishwasher sheet metal parts. Background Technology

[0002] A dishwasher is an electrical appliance that uses electricity to pressurize water and spray it onto the surface of dishes, combining detergent and hot water to automatically wash, rinse, and dry the dishes. Sheet metal parts are the metal plates that make up the dishwasher's shell and frame. During the manufacturing process, these sheet metal parts are prone to developing burrs on their edges due to cutting or punching. To avoid these burrs affecting subsequent assembly accuracy and surface coating quality, they need to be removed by filing.

[0003] In existing technologies, burrs on the edges of sheet metal parts are often removed using a filing machine. However, during the burr removal process, the cutting action of the file causes debris to fly everywhere. This debris easily adheres to the end faces and edges of the sheet metal parts, affecting the cleanliness of the surface and hindering subsequent painting, assembly, and other processes. Furthermore, an additional debris cleaning process is required, leading to longer production cycles, increased processing costs, and reduced overall production efficiency.

[0004] Furthermore, since the file continuously advances along the edge of the sheet metal part, the debris easily adheres to the unpolished area of ​​the sheet metal edge. As a result, when the file advances to this area, it cuts off the debris attached to the surface along with the burrs. This not only increases the filing resistance and affects the filing stability, but also easily leaves irregular scratches on the edge of the workpiece or causes local overcutting, ultimately reducing the edge processing quality and dimensional consistency. Summary of the Invention

[0011] Preferably, a transmission ring is rotatably sleeved on the outer ring of the ring plate, and multiple through-hole rods are evenly distributed and fixedly connected along the circumference of the transmission ring. A guide post is fixedly connected to the adjusting rod, and each guide post slides through the through hole of a through-hole rod. A cylinder three is fixedly installed on the ring plate, and the piston end of the cylinder three is fixedly connected to the end of one side of the adjusting rod.

[0012] Preferably, the second radial traction structure includes a rotating plate fixedly connected to the end face plate. The rotating plate has multiple grooves evenly opened along the circumference. A traction rod is slidably arranged in each groove. The end of the traction rod away from the axis of the end face plate is fixedly connected to the edge of the end face pad. The end face pad is made of elastic material.

[0013] Preferably, a cylinder four is fixedly provided on the rotating plate, and a traction block is fixedly connected to the piston end of the cylinder four. Multiple connecting rods one are evenly distributed and rotatably provided on the traction block along the circumference, and the end of each connecting rod one away from the traction block is rotatably connected to a traction rod.

[0014] Preferably, the processing table is provided with a lead screw linear module, which has two movable ends that can move simultaneously toward or away from each other, and the two movable ends are respectively fixedly connected to two adjusting plates. A motor is fixedly provided on the adjusting plate, and the output end of the motor is fixedly connected to the rotating end of the rotating plate.

[0015] Preferably, the adjusting rod located at the rectangular notch of the edge pad is provided with a notch deformation component;

[0016] The notch deformation assembly includes a cylinder 1 fixedly connected to an adjusting rod. A transmission plate is fixedly connected to the piston end of the cylinder 1. Two connecting rods 2 are symmetrically rotated on the transmission plate. A tension rod is rotatably provided at the end of the connecting rod 2 away from the transmission plate. The tension rod is slidably mounted on the connecting block in the transverse direction. One end of each of the two tension rods is fixedly connected to the two edges of the rectangular notch of the edge pad.

[0017] Preferably, the processing table is equipped with an industrial vacuum cleaner, the air inlet of the industrial vacuum cleaner is connected to an adsorption tube, the adsorption tube's opening passes through an adjusting rod, a connecting block, and an edge pad and extends to the inside of a rectangular notch, one end of the tension rod is rotatably equipped with a brush roller extending to the inside of the rectangular notch, and a second motor for driving the brush roller to rotate is fixed on the tension rod.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The present invention discloses a deburring fixture for sheet metal parts of a dishwasher. Utilizing a notch-type arc-edge covering component and an end-face covering component, during the filing process, due to the coverage of the edge pad, the debris generated during filing is confined to a local area near the rectangular notch, preventing it from splashing onto the unfiled area of ​​the sheet metal part's edge. This effectively avoids the situation where the file cuts the debris attached to the unfiled area along with the burrs, thereby increasing filing resistance and affecting filing stability. At the same time, it also avoids leaving irregular scratches or causing local overcutting on the workpiece edge, ensuring edge processing quality and dimensional consistency.

[0020] Furthermore, because the end faces of the sheet metal parts are covered by end face pads, debris is effectively prevented from splashing onto the end faces. Simultaneously, the filed areas on the edges of the sheet metal parts generate relative friction with the edges of the edge pads as the workpiece rotates. The edge pads intercept the debris, confining it to the rectangular notch, thus ensuring that the end faces and edges of the sheet metal parts maintain good cleanliness after processing. This facilitates subsequent painting, assembly, and other processes. At the same time, it eliminates the need for additional debris cleaning procedures, shortens the production cycle, and improves overall production efficiency.

[0021] 2. The present invention provides a tooling for filing and deburring sheet metal parts for dishwashers. Utilizing a notch deformation component, when a smaller file is used, two tension rods slide simultaneously in opposite directions. This minimizes the width of the rectangular notch without affecting the normal operation of the file, thereby reducing the gap between the file and the sidewall of the rectangular notch. This significantly reduces the area where debris can adhere in the unfiled area, resulting in a substantial reduction in the amount of debris adhering. Consequently, it reduces interference with the filing process caused by debris inclusion when the unfiled area moves to the file, ensuring that filing stability and edge processing quality are maintained even after replacing the file with a smaller one.

[0022] 3. The present invention provides a tooling for filing and deburring sheet metal parts for dishwashers. During the filing process, an industrial vacuum cleaner can be activated, and debris is sucked into the vacuum cleaner through an adsorption tube. Simultaneously, the bristles on the brush roller clean the inner wall of the rectangular notch, making it easier to adsorb debris adhering to the inner wall. This effectively cleans the debris from the inner wall of the rectangular notch, preventing blockage and ensuring the file can move normally, thus improving the filing effect.

[0023] In addition, the bristles on the brush roller can also reach both the unfiled and filed areas, effectively cleaning debris from both areas and further reducing the interference of debris on the filing process. Attached Figure Description

[0035] 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.

[0036] Example 1:

[0037] like Figures 1-5 As shown, a deburring tooling for a dishwasher sheet metal part includes a processing table 1 and a file machine 10. The processing table 1 is provided with a displacement structure for adjusting the position of the file machine 10. The processing table 1 is provided with a notch-type arc edge covering assembly and an end face covering assembly.

[0038] The notched arc edge covering assembly includes an annular edge pad 8 and a first radial traction structure for causing the edge pad 8 to contract radially. The edge pad 8 has a rectangular notch at the top center. Under the traction of the radial traction structure, the edge pad 8 fits tightly against the edge of the circular sheet metal part. The file 33 of the file machine 10 extends into the rectangular notch and fits against the edge of the sheet metal part.

[0039] The end face covering assembly includes two end face plates 17. A circular end face pad 9 is fixedly fitted on the outer edge of the end face plate 17. The end face plate 17 is provided with a second radial traction structure for causing the end face pad 9 to contract radially. The two end face plates 17 and the two end face pads 9 are respectively attached to the two end faces of the sheet metal part. The edge of the end face pad 9 moves to the edge of the sheet metal part under the traction of the second radial traction structure.

[0040] In this embodiment, as Figure 4 As shown, the displacement structure includes a stand 5 fixed on the processing table 1, a second lead screw linear module 16 is provided on the stand 5, a lifting plate 15 is fixedly provided at the moving end of the second lead screw linear module 16, a second cylinder 14 is fixedly provided on the lifting plate 15, and a file machine 10 is fixedly provided at the piston end of the second cylinder 14.

[0041] like Figure 7 As shown, the first radial traction structure includes a ring plate 4 fixedly mounted on the processing table 1. Multiple adjusting rods 12 are evenly distributed and slidably mounted on the ring plate 4 along the circumference. Each adjusting rod 12 is fixedly connected to a connecting block 13 at one end near the axis of the ring plate 4. The multiple connecting blocks 13 are fixedly connected to the edge pad 8, which is made of elastic material.

[0042] like Figure 7 and Figure 8 As shown, a transmission ring 23 is rotatably sleeved on the outer ring of the ring plate 4. Multiple through-hole rods 24 are evenly distributed and fixedly connected along the circumference of the transmission ring 23. A guide post 32 is fixedly connected to the adjusting rod 12. Each guide post 32 slides through the through hole of a through-hole rod 24. A cylinder 31 is fixedly installed on the ring plate 4. The piston end of the cylinder 32 is fixedly connected to the end of the adjusting rod 12 on one side.

[0043] like Figure 5 As shown, the second radial traction structure includes a rotating plate 25 fixedly connected to the end face plate 17. Multiple grooves are evenly opened along the circumference of the rotating plate 25. A traction rod 18 is slidably provided in each groove. The end of the traction rod 18 away from the axis of the end face plate 17 is fixedly connected to the edge of the end face pad 9. The end face pad 9 is made of elastic material.

[0044] like Figure 6 As shown, a cylinder 22 is fixedly mounted on the rotating plate 25. A traction block 26 is fixedly connected to the piston end of the cylinder 22. Multiple connecting rods 19 are evenly distributed and rotated along the circumference of the traction block 26. The end of each connecting rod 19 away from the traction block 26 is rotatably connected to a traction rod 18.

[0045] like Figure 2 As shown, the processing table 1 is provided with a lead screw linear module 7. The lead screw linear module 7 is provided with two moving ends that can move simultaneously towards or away from each other. The two moving ends are respectively fixedly connected to two adjusting plates 6. A motor 20 is fixedly provided on the adjusting plate 6. The output end of the motor 20 is fixedly connected to the rotating end of the rotating plate 25.

[0046] Specifically, this embodiment is applied to removing burrs from the edges of circular sheet metal parts. First, the sheet metal part is placed between two end face plates, with the axis of the sheet metal part coinciding with the axis of the end face plates. Then, the two adjusting plates 6 are driven to slide simultaneously and move closer to each other by the lead screw linear module 7, so that the two end face plates 17 are respectively in contact with the two sides of the sheet metal part, thus clamping the sheet metal part by the end face plates 17.

[0047] Subsequently, cylinder 22 drives the traction block 26 to move laterally, and under the transmission of multiple connecting rods 19, multiple traction rods 18 simultaneously slide in the grooves of the end face plate 17. This allows the end face pad 9 to be stretched through the traction rods 18, causing the edge of the end face pad 9 to move to the edge of the sheet metal part. At this time, the two end face pads 9 cover both sides of the sheet metal part respectively.

[0048] Next, cylinder 21 drives one of the adjusting rods 12 to slide on the ring plate 4. With the transmission cooperation of the through-hole rod 24 and guide post 32, the transmission ring 23 rotates. Multiple adjusting rods 12 then slide synchronously under the cooperation of the through-hole rod 24 and guide post 32, thereby controlling the distance between the adjusting rods 12 and the axis of the ring plate 4. This adjusts the size of the edge pad 8, ensuring that the edge pad 8 fits tightly against the edge of the sheet metal part under the action of elasticity. At this point, the sheet metal part is covered by the edge pad 8 and end face pad 9, exposing only the area at the rectangular notch of the edge pad 8. Then, based on the height of the rectangular notch, the lifting plate 15 is raised and lowered using the lead screw linear module 16, thereby adjusting the height of the file machine 10. This aligns the file 33 with the rectangular notch. Since the size of the rectangular notch is larger than the width of the file 33, cylinder 2 14 can drive the file machine 10 to move laterally, allowing the file 33 to smoothly extend into the rectangular notch and contact the edge of the sheet metal part. At this time, there is a certain gap between the file 33 and the side wall of the rectangular notch, providing working space for the file 33.

[0049] Subsequently, the rotating plate 25 is rotated by the motor 20, which in turn causes the sheet metal parts to rotate.

[0050] When the sheet metal part rotates, the file 33 moves relative to the sheet metal part, and the file 33 files along the edge of the sheet metal part. During the filing process, due to the coverage of the edge pad 8, the debris generated by filing is confined to a local area near the rectangular notch, and cannot splash to the unfiled area of ​​the sheet metal edge. This effectively avoids the situation where the file 33 cuts along with burrs attached to the unfiled area 34, which would increase filing resistance and affect filing stability. At the same time, it also avoids leaving irregular scratches or causing local overcutting on the edge of the workpiece, ensuring the edge processing quality and dimensional consistency. In addition, even if there is a gap between the file 33 and the side wall of the rectangular notch, this gap is only to allow the file 33 to move smoothly, and the area where debris can adhere is negligible, so the negative impact on filing is also negligible.

[0051] Furthermore, since the end faces of the sheet metal parts are covered by the end face pads 9, debris is effectively prevented from splashing onto the end faces. Simultaneously, the filed areas on the edges of the sheet metal parts will experience relative friction with the edges of the edge pads 8 as the workpiece rotates. The edge pads 8 intercept the debris, confining it to the rectangular notch, thus ensuring that the end faces and edges of the sheet metal parts maintain good cleanliness after processing. This facilitates subsequent painting, assembly, and other processes. At the same time, it eliminates the need for additional debris cleaning procedures, shortens the production cycle, and improves overall production efficiency.

[0052] Example 2:

[0053] In this embodiment, as Figure 7 , Figure 9 , Figure 10 As shown, the adjusting rod 12 located at the rectangular notch of the edge pad 8 is equipped with a notch deformation component;

[0054] The notch deformation assembly includes a cylinder 11 fixedly connected to the adjusting rod 12. The piston end of the cylinder 11 is fixedly connected to a transmission plate 30. Two connecting rods 29 are symmetrically rotated on the transmission plate 30. A tension rod 31 is rotatably provided at the end of the connecting rod 29 away from the transmission plate 30. The tension rod 31 is slidably disposed on the connecting block 13 in the transverse direction. One end of the two tension rods 31 is fixedly connected to the two sides of the rectangular notch of the edge pad 8.

[0055] Specifically, in the above embodiments, although the area of ​​debris adhesion between the file 33 and the sidewall of the rectangular notch is negligible, in actual processing, it is sometimes necessary to replace the file 33 with a smaller size according to the filing requirements. As the size of the file 33 decreases, the area of ​​the sheet metal edge covered by the file 33 decreases accordingly, and the distance between the file 33 and the sidewall of the rectangular notch increases accordingly. This results in a corresponding increase in the amount of debris that can adhere to the unfiled area 34 during the filing process, which in turn causes the debris to interfere more severely with the filing work when the unfiled area 34 moves to the file 33.

[0056] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0057] When replacing the file 33 with a smaller size file, the cylinder 11 can drive the transmission plate 30 to move vertically, and the connecting rod 29 can drive the two tension rods 31 to slide simultaneously in opposite directions. Without affecting the normal operation of the file 33, the width of the rectangular notch is minimized to the greatest extent, thereby reducing the gap between the file 33 and the side wall of the rectangular notch. This significantly reduces the area on which debris can adhere in the unfiled area 34, thus significantly reducing the amount of debris. This reduces the interference of debris on the filing process when the unfiled area 34 moves to the file 33, ensuring that filing stability and edge processing quality can still be maintained after replacing the file 33 with a smaller size file.

[0058] Example 3:

[0059] like Figure 1 , Figure 3 , Figure 9 As shown, an industrial vacuum cleaner 2 is provided on the processing table 1. The air inlet of the industrial vacuum cleaner 2 is connected to an adsorption pipe 3. The opening of the adsorption pipe 3 passes through the adjusting rod 12, the connecting block 13, the edge pad 8 and extends to the inside of the rectangular notch. One end of the tension rod 31 is rotatably provided with a brush roller 27 extending to the inside of the rectangular notch. A motor 28 for driving the brush roller 27 to rotate is fixed on the tension rod 31.

[0060] Specifically, in the above embodiment, although the debris attached to the filed area 35 is intercepted by the edge pad 8, the debris will also accumulate in the rectangular notch and adhere to its inner wall. When the debris accumulates to a certain amount, it will cause the notch to be blocked, thereby interfering with the normal movement of the file 33, resulting in increased filing resistance and affecting the filing effect.

[0061] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0062] When the position of the tension rod 31 changes, the brush roller 27 also moves accordingly, ensuring that the bristles on its surface are in close contact with the inner wall of the rectangular notch. During the filing process, the industrial vacuum cleaner 2 can be activated to generate negative pressure suction at the opening of the suction tube 3, drawing debris into the industrial vacuum cleaner 2 through the suction tube 3. Simultaneously, the motor 28 drives the brush roller 27 to rotate, using the bristles on the brush roller 27 to clean the inner wall of the rectangular notch, making it easier to adsorb the debris adhering to the inner wall. This effectively cleans the debris from the inner wall of the rectangular notch, preventing the rectangular notch from becoming clogged and ensuring that the file 33 can move normally, thus improving the filing effect.

[0063] In addition, the bristles on the brush roller 27 can also contact the unfiled area 34 and the filed area 35, which also plays a role in cleaning the debris in the two areas, further reducing the interference of debris on the filing process.
