Description

Technical Field

[0001] This utility model relates to the field of processing fixture technology, and in particular to a side pressing fixture for water tank decorative parts. Background Technology

[0002] In the manufacturing of high-end kitchen and bathroom equipment, sheet metal sink decorative parts (such as thin stainless steel and titanium alloy sheets) require high-precision milling and drilling processes by CNC machining centers before edge pressing and assembly. There is a need to machine holes in the thickness direction of these sheet metal sink decorative parts. Conventional fixtures often use V-blocks or simple edge guards for positioning. For thin sheet parts with a thickness ≤1mm, their poor rigidity makes them prone to elastic deformation, resulting in a cumulative drilling position error exceeding ±0.5mm. This problem is even more pronounced when the decorative part has a curved surface. Another commonly used fixture uses a top pressure bar type, where the pressure arm applies pressure from above the workpiece, blocking the side drilling area. This forces the operator to frequently disassemble and assemble the fixture, increasing the processing time per piece by more than 40%. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a side pressing fixture for water tank decorative parts, which simultaneously limits and locks the parts from the side with the limiting structure to avoid obstructing the drilling area.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a side pressing fixture for a water tank decorative part, including a limiting seat, a locking groove extending through the length direction of the limiting seat, a limiting groove being formed based on the edge of the locking groove; and a pressing component being provided in the locking groove and closely attached to the limiting groove.

[0005] To ensure the lateral pressing function of the sink decorative parts is realized, the pressing assembly further includes a movable block and a pressing block that are fitted together. The edge of the movable block is in contact with the edge of the pressing block, and the side of the pressing block facing the movable block is inclined. The movable block is driven by a cylinder located below the limiting seat to reciprocate vertically.

[0006] To ensure the coordinated movement of the movable block and the pressing block constituting the pressing assembly, a fitting block is further provided on the side of the movable block facing the pressing block, and a fitting opening matching the shape of the fitting block is provided on the side of the pressing block facing the movable block.

[0007] To ensure the lateral pressing effect of the pressing assembly on the sink decoration, further, when the pressing assembly is in the pressing position, the distance from the side of the pressing block facing the limiting groove to the edge of the limiting groove is not greater than the thickness of the sink decoration.

[0008] To better achieve the pressing and fixing of the decorative parts of the sink and ensure the pressing effect from the side, a pre-pressing component is further provided on the side of the pressing block facing the limiting groove. The pre-pressing component includes an elastic structure and a pre-pressing block, with both ends of the elastic structure connected to the pressing block and the pre-pressing block respectively. An anti-slip structure is provided on the side of the pre-pressing block facing the limiting groove.

[0009] To prevent the pre-pressing component set in the relaxed state from obstructing the placement of the sink decoration into the limiting groove, further, when the pressing component is in the relaxed position, the distance from the side of the pressing block facing the limiting groove to the edge of the limiting groove is not greater than the sum of the widths of the sink decoration and the pre-pressing component.

[0010] To ensure the ease of inserting the decorative sink piece into the limiting groove and to ensure that the limiting groove has a certain length-direction limiting function, the limiting groove is further defined as being opened from one end of the locking groove to the other end, and the length of the limiting groove is less than the length of the locking groove.

[0011] To facilitate quick removal of the decorative sink parts after processing, a quick-release opening is further provided at the end edge of the limiting groove.

[0012] To facilitate the fixation of the entire pressing fixture, a support foot is provided below the limiting seat for support, and a fixing groove is provided on the support foot.

[0013] Compared with the prior art, the beneficial effects of this utility model include: by providing a locking groove in the limiting seat and opening a limiting groove based on the locking groove to provide initial positioning for the sink decoration, and then completing the locking and fixing of the sink decoration by the pressing component set in the locking groove.

Detailed Implementation

[0016] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0017] A lateral pressing fixture for sink decorative parts, such as Figure 1 As shown, the device includes a limiting seat 1, with a locking groove 2 extending through its length. A further limiting groove 3 is formed along the edge of the locking groove 2. The length of the limiting groove 3 is no greater than the length of the locking groove 2, and the width of the limiting groove 3 is no greater than the thickness of the sink decoration. This forms a limiting groove 3 that provides a barrier for positioning the sink decoration, ensuring that the sink decoration is positioned within the length of the locking groove 2. A quick-release opening 11 is provided at the end edge of the limiting groove 3. Then, a pressing assembly 4, positioned within the locking groove 2 and closely abutting the limiting groove 3, presses the sink decoration into the limiting groove 3 from the side, thus locking and fixing the sink decoration for subsequent processing. At least two sets of pressing assemblies 4 are used, based on the length distribution of the sink decoration, so that the two sets of pressing assemblies 4 can precisely lock and fix both ends of the sink decoration. If the number of pressing assemblies 4 is greater than two sets, they are evenly spaced based on the length of the sink decoration.

[0018] The following combination Figure 2 The pressing assembly 4 is described below. The pressing assembly 4 includes a movable block 6 and a pressing block 5 that are fitted together. When the decorative part of the sink is in the locking position, the edge of the movable block 6 is completely in contact with the edge of the pressing block 5. When the two move relative to each other, the edge of the movable block 6 can also be in contact with the edge of the pressing block 5. The movable block 6 is driven by a cylinder 12 located under the limiting seat 1 to reciprocate vertically. The stroke of the cylinder 12 is not greater than the height of the movable block 6, so as to ensure that there is always a contact part between the edges of the movable block 6 and the pressing block 5.

[0019] The following provides a detailed explanation of the edge fit between the aforementioned pressing block 5 and the movable block 6. The edges of the pressing block 5 and the movable block 6 always remain tightly fitted, and the edge line of the pressing block 5 facing the movable block 6 descends from top to bottom. In fact, the pressing block 5 is a right-angled trapezoidal structure, and the side of the pressing block 5 opposite to the movable block 6 forms the hypotenuse of the trapezoid. The side of the movable block 6 opposite to the pressing block 5 forms an inverted trapezoidal hypotenuse structure that matches the shape of the pressing block 5. Through the aforementioned structural design of the pressing block 5 and the movable block 6, when the position of the movable block 6 relative to the pressing block 5 changes, their edges remain in contact.

[0020] When the aforementioned movable block 6 is in the locking position, the upper plane of the movable block 6 is slightly higher than or exactly flush with the upper plane of the pressing block 5. At this time, the pressing block 5 moves towards the limiting groove 3 under the squeezing and pushing action of the movable block 6, thereby squeezing and locking the sink decoration in the limiting groove 3. When the movable block 6 gradually moves upward, the cross-sectional area of ​​the movable block 6 and the pressing block 5 on the same plane becomes smaller, and the lateral squeezing force given to the pressing block 5 by the inclined structure becomes smaller, thereby causing the pressing block 5 to be relaxed. The lateral squeezing force on the sink decoration also decreases synchronously until one side of it is no longer in close contact with the inner wall of the limiting groove 3 until there is no squeezing force at all. At this time, the movable block 6 is in the relaxing position, and the sink decoration can be manually removed.

[0021] It is worth noting that pressing blocks 5 can be provided on both sides of the aforementioned movable block 6. During the vertical reciprocating motion of the movable block 6, the pressing blocks 5 on both sides are driven by the movable block 6 to complete the pressing process of the water tank decorative parts located on the left and right sides of the movable block 6. This helps to lock and fix multiple water tank decorative parts at the same time and improve the processing efficiency of the water tank decorative parts.

[0022] In some embodiments, the pressing blocks 5 located on both sides of the movable block 6 are connected by an elastic structure. When the movable block 6 moves vertically upward to the relaxation position, the pressing blocks 5 on both sides of the movable block 6 will contract towards the center under the action of the elastic structure, thereby reducing the pressure exerted on the sink decoration until the pressure exerted on the sink decoration is zero. In this embodiment, the distance between adjacent pressing blocks 5 is adjusted by the elastic structure. When the movable block 6 re-enters the locking position, the inclined structure on its outer edge that cooperates with its two sides can effectively push the pressing blocks 5 on both sides outward, thereby realizing the pressing effect on the sink decoration in the limiting groove 3.

[0023] In other implementations, such as Figure 2 and Figure 3As shown, a fitting block 7 is provided on the side of the movable block 6 facing the pressing block 5, and a fitting opening 10 matching the shape of the fitting block 7 is provided on the side of the pressing block 5 facing the movable block 6. The aforementioned fitting block 7 is arranged along the inclined section direction of the side of the movable block 6 facing the pressing block 5, and the fitting opening 10 is arranged along the inclined section direction of the side of the pressing block 5 facing the movable block 6. With the cooperation relationship between the fitting block 7 and the fitting section, during the vertical reciprocating movement of the movable block 6, the pressing blocks 5 located on both sides of the movable block 6 can change their spacing according to the different positions of the movable block 6, thereby synchronously driving the pressing block 5 to press the water tank decorative part while only moving the movable block 6.

[0024] like Figure 4 As shown, the aforementioned fitting block 7 includes an extension section 9 and a mating section 8. The mating section 8 has a square cross-section, and its width is greater than that of the extension section 9, to ensure that the fitting block 7 will not dislodge from the fitting opening 10 due to lateral movement. The cross-sectional shape of the mating section 8 can be any shape, as long as its maximum width is greater than that of the extension section 9.

[0025] It should be noted that when the pressing component 4 is in the pressing position, that is, when the aforementioned movable block 6 is in the locking position, the distance from the side of the pressing block 5 facing the limiting groove 3 to the edge of the limiting groove 3 is not greater than the thickness of the sink decoration, so as to ensure that the pressing block 5 can lock the sink decoration in the locking position.

[0026] In a further implementation, such as Figure 5 As shown, a pre-pressing component is provided on the side of the pressing block 5 facing the limiting groove 3. The pre-pressing component includes an elastic structure 15 and a pre-pressing block 16. The two ends of the elastic structure 15 are connected to the pressing block 5 and the pre-pressing block 16, respectively. The elastic structure 15 can be a spring. The pre-pressing component initially presses the sink decoration into the limiting groove 3. As the pressing block 5 moves towards the limiting groove 3 under the push of the movable block 6, and under the synchronous action of the sink decoration, the elastic structure 15 is compressed. The compressed elastic structure 15 can provide additional thrust to the pre-pressing block 16. When the pressing block 5 moves to the limit position, the elastic structure 15 is compressed to a certain extent and can be regarded as a fixed-length connector. At this time, under the dual pressure of the pressing block 5 and the elastic structure 15, the sink decoration can be better pressed into the limiting groove 3. To prevent the decorative sink parts from shifting laterally along the length of the limiting groove 3 during processing, an anti-slip structure, such as an anti-slip texture or a soft pad with a rough surface, is provided on the side of the pre-pressing block 16 facing the limiting groove 3. The pad can both prevent slipping and protect the surface of the decorative sink parts.

[0027] It is worth noting that when the pressing component 4 is in the relaxed position, that is, when the movable block 6 is at its uppermost position, the distance between the pressing blocks 5 on both sides of the movable block 6 is the smallest. At this time, the distance from the side of the pressing block 5 facing the limiting groove 3 to the edge of the limiting groove 3 should not be greater than the sum of the widths of the sink decoration and the pre-pressing component. This is to ensure that when the pressing component 4 is in the relaxed position, the pre-pressing block 16 will not exert force on the sink decoration, so as to ensure that the sink decoration can be directly placed into the limiting groove 3.

[0028] like Figure 1 As shown, a support foot 13 for support is provided below the aforementioned limiting seat 1, and a fixing groove 14 is provided on the support foot 13. The machining fixture can be locked and fixed in the CNC machining center through the fixing groove 14. The subsequent processing of the water tank decorative part can be started by partitioning and pressing it.

[0029] A locking groove 2 is provided in the limiting seat 1, and a limiting groove 3 is opened based on the locking groove 2 to provide initial positioning for the sink decoration. Then, the pressing component 4 set in the locking groove 2 completes the locking and fixing of the sink decoration. The pressing component 4 is composed of a movable block 6 and a pressing block 5. The linkage between the movable block 6 and the pressing block 5 is achieved through the trapezoidal structure cooperation, which converts the vertical movement of the movable block 6 into the lateral movement of the pressing block 5. The linkage between the movable block 6 and the pressing block 5 ensures the cyclical use of the fixture, which is conducive to the continuous processing and improves the processing efficiency of the sink decoration.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
