Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a downward-pressing deburring device. Background Technology

[0002] Silicone filter pads were developed to address the problems of traditional filter pads, such as poor drainage, easy bacterial growth, and inconvenient cleaning. Made of silicone, they possess excellent flexibility, high-temperature resistance, and corrosion resistance, effectively filtering out water. Figure 1 As shown, the unique structural design of the silicone filter pad workpiece 501 results in multiple arc-shaped holes in the middle. However, during the molding process, silicone is prone to overflowing into the arc-shaped holes, resulting in burrs 502, which adversely affects the appearance and filtration effect of the filter pad workpiece 501. The arc-shaped hole structure is complex, making manual trimming of the burrs 502 inconvenient. Moreover, the burrs 502 are relatively soft and cannot be directly removed like hard materials.

[0023] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0024] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0026] An embodiment of this utility model provides a downward-pressing deburring device, such as... Figure 1-6 As shown, it includes: a worktable 101, a fixed structure 102 disposed on the worktable 101, an upper pressing mechanism 201 disposed above the fixed structure 102, a lower pressing mechanism 202 disposed below the fixed structure 102, and a positioning structure 203 for guiding the upper pressing mechanism 201 and the lower pressing mechanism 202 to dock. The fixed structure 102 is used to place the workpiece 501 to be deburred 502.

[0027] The upper pressing mechanism 201 includes a first pressing plate structure 204, a detachable first stamping block 205 disposed on the first pressing plate structure 204, and a driving structure 206 for driving the first pressing plate structure 204 to move relative to the lower pressing mechanism 202. The lower pressing mechanism 202 includes a second pressing plate structure 207 and a second stamping block 208 disposed on the second pressing plate structure 207. The second stamping block 208 can pass through the fixed structure 102 and dock with the first stamping block 205. When the equipment is working, the driving structure 206 can first drive the first pressing plate structure 204 to move towards the fixed structure 102 to press the workpiece 501. The burr 502 of the workpiece 501 can be clamped by the first stamping block 205 and the second stamping block 208. Then, the driving structure 206 can drive the first stamping block 205 to press down so that the burr 502 is separated from the workpiece 501.

[0028] The detachable first stamping block 205 design increases the versatility of the equipment. When processing workpieces 501 with different materials, burr thicknesses, or shapes, the first stamping block 205 can be replaced. The upper pressing mechanism 201 and the lower pressing mechanism 202 can cooperate to clamp the workpiece 501 and remove the burrs 502. The fixed structure 102 is used to place the workpiece 501 to be deburred. During the stamping deburring process, the workpiece 501 is subjected to a large pressure. Since the silicone burrs 502 are too soft, the fixed structure 102 can prevent the workpiece 501 from shifting or deforming during the stamping process, providing a stable support platform for the workpiece 501. Specifically, when the workpiece 501 is placed on the fixed structure 102, the top of the second stamping block 208 abuts against the bottom of the burr 502, which facilitates clamping the soft burrs 502 after being pressed down and connected with the first stamping block 205. The driving structure 206 drives the first pressure plate structure 204 downward, causing the first stamping block 205 and the second stamping block 208 to press down, thus separating the burr 502 from the workpiece 501. In practice, the first stamping block 205 and the second stamping block 208 have the same shape as the arc-shaped hole of the workpiece 501. The fixing structure 102 has multiple through slots with the same shape as the arc-shaped hole of the workpiece 501. The first stamping block 205 and the second stamping block 208 can pass through these through slots to dock and slide up and down, ensuring the accuracy of burr removal. The positioning structure 203 is used to guide the lower pressing mechanism 202 to dock with the upper pressing mechanism 201, which makes the stamping process more precise and ensures that the first stamping block 205 and the second stamping block 208 can accurately dock in each working cycle, reducing the possibility of incomplete burr removal or damage to the workpiece 501 due to positional deviation.

[0029] In some embodiments, such as Figure 2-3 As shown, the fixing structure 102 includes a fixing plate 103 for placing the workpiece 501 and a height adjustment structure 104 for adjusting the height of the fixing plate 103. The fixing plate 103 has a plurality of through holes through which the first stamping block 205 and the second stamping block 208 can pass.

[0030] The height adjustment structure 104 can flexibly adjust the height of the fixing plate 103 according to the different thicknesses and structures of the workpiece 501, greatly improving the versatility and production efficiency of the equipment. This ensures that the workpiece 501 is precisely positioned in the optimal processing position of the upper pressing mechanism 201 and the lower pressing mechanism 202, guaranteeing consistent deburring results. In practice, the fixing plate 103 has multiple through slots with shapes consistent with the arc-shaped holes of the workpiece 501.

[0031] Furthermore, such as Figure 2-3As shown, the height adjustment structure 104 includes a first push plate 105 disposed below the worktable 101, a push structure 106 for pushing the first push plate 105 to move up and down, and a connecting rod 107 connecting the first push plate 105 and the fixed plate 103.

[0032] The first push plate 105 is moved up and down by a drive structure 106 driven by a motor and cylinder. The motion is then transmitted to the fixed plate 103 by a connecting rod 107, thereby achieving precise height adjustment of the fixed plate 103. The structure is simple and compact, reducing production costs and maintenance difficulties. In practice, the drive structure 106 passes through the first push plate 105 and is fixed below the worktable 101. The bottom of the first push plate 105 is pushed by a push rod to adjust the height of the fixed plate 103.

[0033] Furthermore, such as Figure 2 , 4 As shown, the second pressure plate structure 207 includes a first pressure plate 209 slidably connected to the connecting rod 107 and disposed below the fixed plate 103, and a first spring structure 210 connecting the first pressure plate 209 and the worktable 101. The second stamping block 208 is disposed on the first pressure plate 209.

[0034] The first pressure plate 209 is slidably connected to the connecting rod 107 to ensure the accuracy of the up-and-down movement of the fixed plate 103. In conjunction with the first spring structure 210 set at the bottom of the first pressure plate 209, it buffers the impact force when the first stamping block 205 presses down, making the stamping process smoother and reducing damage to the workpiece 501. At the same time, the elastic restoring force of the spring allows the first pressure plate 209 to quickly return to its original position. The structure is simple, easy to maintain and cost-effective.

[0035] In some embodiments, such as Figure 2-5 As shown, the first pressure plate structure 204 includes a second pressure plate 211 connected to the drive structure 206, a third pressure plate 212 disposed below the second pressure plate 211 and slidably connected to the first stamping block 205, and a second spring structure 213 connecting the second pressure plate 211 and the third pressure plate 212. The first stamping block 205 is disposed at the bottom of the second pressure plate 211, and the first stamping block 205 can pass downward through the third pressure plate 212 and dock with the second stamping block 208.

[0036] The initial state of the equipment is as follows Figure 3 As shown, after startup, the drive structure 206 pushes the second pressure plate 211 and the third pressure plate 212 downwards together until... Figure 4 At the position shown, the third pressure plate 212 abuts against the fixed plate 103, clamping the workpiece 501. Meanwhile, the first stamping block 205 engages with the second stamping block 208 passing through the fixed plate 103, clamping the burr 502. Subsequently, the drive structure 206 continues to push the second pressure plate 211 downwards until... Figure 5At the position shown, the second spring structure 213 is compressed, the first stamping block 205 is inserted downward into the fixing plate 103, and the second stamping block 208 is also pressed down synchronously, but the workpiece 501 remains on the fixing plate 103, realizing the separation of the burr 502 and the workpiece 501. The stamping process is stable, reducing damage to the workpiece 501 and achieving a good deburring effect for the burr 502.

[0037] Furthermore, such as Figure 6 As shown, the fixing plate 103 is provided with a placement groove 108 that matches the bottom shape of the workpiece 501, and the third pressure plate 212 includes a plurality of clamping blocks 214 that match the top shape of the workpiece 501. The clamping blocks 214 are used to clamp the workpiece 501 placed in the placement groove 108.

[0038] The placement groove 108 matches the shape of the workpiece 501, which can accurately position the workpiece 501 and ensure its stable position during processing. The clamping block 214 can effectively clamp the workpiece 501 to prevent it from shifting during stamping.

[0039] Furthermore, such as Figure 3-5 As shown, the positioning structure 203 includes a guide post 215 disposed on the fixed plate 103 and a guide sleeve 216 disposed on the second pressure plate 211. As the second pressure plate 211 moves down, the guide post 215 can be inserted into the guide post 216.

[0040] As the second pressure plate 211 moves down, the guide post 215 can be inserted into the guide sleeve 216 to achieve precise positioning, ensuring that the upper pressing mechanism 201 and the lower pressing mechanism 202 are accurately connected during the stamping process, reducing processing errors caused by position deviation.

[0041] Furthermore, such as Figure 6 As shown, the positioning structure 203 also includes a conical positioning block 217 disposed below the third pressure plate 212. The tip of the conical positioning block 217 points downwards, and the fixing plate 103 has a positioning groove 218 that cooperates with the conical positioning block 217. The conical positioning block 217 can be inserted into the positioning groove 218.

[0042] With the tip of the conical positioning block 217 pointing downwards, the conical positioning block 217 can be guided into the positioning groove 218 during the downward movement of the third pressure plate 212. This conical mating structure can automatically correct positional deviations and ensure precise alignment for each stamping.

[0043] In some embodiments, such as Figure 2-5 As shown, a downward-pressing deburring device also includes an air blowing device disposed between the fixed structure 102 and the second pressure plate structure 207, and an air blowing pipe 301 disposed on one side of the second stamping block 208. The air blowing device can blow out high-speed gas through the air blowing pipe 301.

[0044] Air pumps, cylinders, and other air blowing devices 301 can blow high-speed gas through air blowing pipes 301 to a designated location, which facilitates the cleaning of cut-off burrs 502, prevents burrs 502 from remaining inside the equipment, and reduces the impact of burrs 502 on subsequent processing or equipment operation.

[0045] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
