Description

Technical Field

[0001] This utility model relates to the field of processing fixture technology, and in particular to a processing fixture for slotting decorative pieces. Background Technology

[0002] There is a decorative piece 1, whose structure is as follows: Figure 1 As shown, its overall structure includes a straight segment 11 and a curved segment 12, and the straight segment 11 and the curved segment 12 are smoothly connected. A first groove 13 is processed along the length direction of the straight segment 11 and penetrates its thickness direction. The first groove 13 is evenly distributed along the width direction of the straight segment 11 and the length of the first groove 13 is less than the length of the decorative piece 1. A second groove 14 is opened on one side of the straight segment 11 near the back of the curved segment 12. The second groove 14 is also based on the length direction of the straight segment 11, and the depth of the second groove 14 is less than the thickness of the straight segment 11 and the length of the second groove 14 is much less than the length of the first groove 13.

[0003] Because the end of the first groove 13 is close to the end of the straight section 11, it is impossible to complete the simultaneous processing of the first groove 13 and the second groove 14 by the same clamping action of the decorative piece 1. Therefore, the processing of the first groove 13 and the second groove 14 needs to be completed in two steps. If the decorative piece 1 cannot be completely fixed, vibration and displacement will occur during its processing, which will affect the processing, its consistency and aesthetics. If it is tightened too much, it will affect the processing of the first groove 13 and the second groove 14. Therefore, the processing needs to be completed in two steps again, which reduces the processing efficiency of the decorative piece 1. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a processing fixture for slotting decorative pieces, which takes into account the processing of two different grooves on the decorative pieces, ensuring the consistency and aesthetics of the decorative pieces while also taking into account processing efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a processing fixture for slotting decorative pieces, including a base and a positioning groove opened along the length or width direction of the base, wherein the length of the positioning groove is not less than the length of the decorative piece, and at least one set of locking components is provided based on at least one end of the positioning groove.

[0006] To ensure the locking effect of the decorative piece in the positioning groove, the locking assembly further includes a cylinder and a locking block. A fixing hole penetrating the thickness direction is provided on the base. The telescopic rod of the cylinder passes through the fixing hole from below the base, and the locking block is fixedly installed at the end of the telescopic rod.

[0007] To accommodate the overall structure of the decorative piece having straight and curved sections, the locking block further includes a connecting section and a locking section disposed at at least one end of the connecting section.

[0008] To press the decorative piece into the positioning groove, the shape of the pressing block facing the decorative piece is aligned with the back of the decorative piece. At this time, the inner side of the curved section of the decorative piece faces the positioning groove. Furthermore, the top of the connecting section is flush with the top of the locking section, and the thickness of the connecting section is greater than the thickness of the locking section. An arc-shaped section matching the shape of the decorative piece is provided at one end of the locking section near the connecting section.

[0009] To press the decorative piece into the positioning groove, the shape of the pressing block facing the decorative piece is aligned with the front of the decorative piece. At this time, the outer side of the curved section of the decorative piece faces the positioning groove. The pressing block is used to press and fix one end of the curved section of the decorative piece. Furthermore, the top of the connecting section and the locking section are flush, and the thickness of the locking section is greater than the thickness of the connecting section. An arc-shaped section matching the shape of the decorative piece is provided near the end of the locking section adjacent to the connecting section.

[0010] To press the decorative piece into the positioning groove, a pressure block is used to press and fix one end of the straight section of the decorative piece. Furthermore, the connecting section and the locking section have the same thickness, and the length of the locking block is greater than the distance from the fixing hole to the positioning groove.

[0011] To conform to the shape of the decorative piece to be pressed and fixed, the positioning groove further includes a horizontal section and a limiting section, with the limiting section connected to one end of the horizontal section.

[0012] To ensure the processing conditions of the first and second grooves on the decorative piece, the distance between adjacent locking components is further less than either the width or the length of the decorative piece.

[0013] To facilitate fixing the entire machining fixture in the CNC machining center to complete the machining process of the decorative piece, a fixing foot is further provided under the base, and several assembly holes are provided through the thickness direction of the fixing foot.

[0014] Compared with the prior art, the beneficial effects of this utility model include: 1) The decorative piece is initially positioned by the positioning groove set on the base, and then the decorative piece is further locked in the positioning groove by the locking component set at at least one end of the positioning groove. 2) By adjusting the distance between adjacent or opposite locking components, the processing requirements of the first and second grooves on the decorative piece are met, thereby obtaining a decorative piece with uniform specifications and aesthetic appeal.

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.

[0018] A processing fixture for slotting decorative pieces includes a base 2 and a positioning groove 3 formed along the length or width of the base 2. The length of the positioning groove 3 is not less than the length of the decorative piece 1 so that the decorative piece 1 can be completely placed in the positioning groove 3, and the positioning groove 3 provides support for the decorative piece 1 to prevent the decorative piece 1 from deforming during its processing. At least one set of locking components is provided at at least one end of the aforementioned positioning groove 3 to complete the overall or partial pressing of the decorative piece 1.

[0019] The aforementioned locking assembly includes a cylinder and a locking block. A fixing hole extending through the thickness direction is provided on the base 2. The telescopic rod of the cylinder passes through the fixing hole from below the base 2, and the locking block is fixedly installed at the end of the telescopic rod. The locking block includes a connecting section and a locking section disposed at at least one end of the connecting section. The connecting section connects the locking block and the telescopic rod of the cylinder into one unit, and the locking section presses the decorative piece 1 into the positioning groove 3.

[0020] The aforementioned positioning groove 3 includes a horizontal section 31 and a limiting section 32. The horizontal section 31 corresponds to the straight section 11 of the decorative piece 1, while the limiting section 32 needs to be determined according to whether the decorative piece 1 is placed facing forward or backward.

[0021] A fixing foot 5 is provided under the base 2, and a number of mounting holes 51 are provided through the thickness direction of the fixing foot 5. The entire machining fixture can be locked and fixed in the CNC machining center through the mounting holes 51 to assist in the machining process of the decorative piece 1.

[0022] The structure and function of the machining fixture will be described in detail below with reference to the embodiments.

[0023] Example 1 A machining fixture for slotting decorative pieces, such as Figure 2 As shown, it includes a base 2 and a positioning groove 3 opened along the length of the base 2. There are two positioning grooves 3, which are symmetrically distributed on the base 2. The telescopic rod of the first cylinder 41 extends out from the area between the two positioning grooves 3 and connects with the first locking block 42.

[0024] The number of positioning grooves 3 can be exactly the length of the decorative piece 1 or multiple times the length of the decorative piece 1, and a gap area is reserved on the basis of multiple times the length of the decorative piece 1, so that multiple decorative pieces 1 can be placed in a single limiting groove while avoiding contact between the decorative pieces 1.

[0025] like Figure 3As shown, in this embodiment, the second groove 14 of the decorative piece 1 is processed, so the front of the decorative piece 1 faces the positioning groove 3, that is, the end of the curved section 12 of the decorative piece 1 faces the positioning groove 3. The horizontal section 31 of the positioning groove 3 is away from the connection between the telescopic rod of the first cylinder 41 and the first locking block 42, while the limiting section 32 is close to the connection between the telescopic rod of the first cylinder 41 and the first locking block 42. The limiting section 32 is a downwardly extending conical groove, and the end of the curved section 12 of the decorative piece 1 abuts against the tip of the conical groove.

[0026] The first locking block 42 presses the decorative piece 1 into the positioning groove 3 from above. The side of the first locking block 42 facing the decorative piece 1 is in contact with the surface of the decorative piece 1. Specifically, the first locking block 42 includes a connecting section and locking sections at both ends of the connecting section. The top of the connecting section is flush with the top of the locking section and the thickness of the connecting section is greater than the thickness of the locking section. An arc-shaped section matching the curved section 12 of the decorative piece 1 is provided at one end of the locking section near the connecting section, which is used to completely press and fix the decorative piece 1 into the positioning groove 3.

[0027] It is worth noting that for a single decorative piece 1, two sets of first locking components 4 are required to press and fix it, specifically, pressing and fixing is performed at both ends along the length of the decorative piece 1. In this embodiment, to facilitate the processing of the second groove 14, the distance between adjacent first locking blocks 42 is not less than the length of the second groove 14, in order to ensure the processing conditions of the second groove 14.

[0028] Example 2 A machining fixture for slotting decorative pieces, such as Figure 4 As shown, it includes a base 2 and a positioning groove 3 that extends through the width of the base 2. There are two positioning grooves 3, which are symmetrically distributed on the base 2. The telescopic rod of the second cylinder 51, which forms the second locking assembly 5, also extends out from the area between the two positioning grooves 3 and connects with the locking block.

[0029] like Figure 5 As shown, in this embodiment, the first groove 13 of the decorative piece 1 is processed, so the back of the decorative piece 1 faces the positioning groove 3, that is, the outer side of the curved section 12 of the decorative piece 1 faces the positioning groove 3. The horizontal section 31 of the positioning groove 3 is far away from the connection between the telescopic rod of the second cylinder 51 and the locking block, while the limiting section 32 is close to the connection between the telescopic rod of the second cylinder 51 and the second locking block 52. The limiting section 32 is an arc-shaped section that fits against the outer edge of the curved section 12 of the decorative piece 1.

[0030] The second locking block 52 presses the decorative piece 1 into the positioning groove 3 from above. The side of the second locking block 52 facing the decorative piece 1 is in contact with the surface of the decorative piece 1. Specifically, the second locking block 52 includes a connecting section and locking sections at both ends of the connecting section. The top of the connecting section and the locking section are flush, and the thickness of the locking section is greater than the thickness of the connecting section. An arc-shaped section matching the shape of the decorative piece 1 is provided at one end of the locking section near the connecting section.

[0031] The aforementioned locking block only presses one end of the curved section 12 of the decorative piece 1 into the positioning groove 3, and another third locking component 6 is used to press and fix the other end of the decorative piece 1 in the width direction.

[0032] The aforementioned third locking assembly 6 includes a third cylinder 61 and a third locking block 62. The third cylinder 61 is a rotary cylinder. The third locking block 62 also includes a connecting section and a locking section. The locking section is located at one end of the connecting section. The connecting section and the locking section have the same thickness. The length of the third locking block 62 must be greater than the distance from the fixing hole 51 through which the third cylinder 61 passes to the positioning groove 3 on the base 2, so as to ensure that the third locking assembly 6 can press and fix one end of the straight section 11 of the decorative piece 1.

[0033] The decorative piece 1 is pressed and fixed on both sides in the width direction using the aforementioned second locking assembly 5 and third locking assembly 6. To ensure the stability of the decorative piece 1 during processing, at least two sets of second locking assemblies 5 or third locking assemblies 6 are applied to one side of the decorative piece 1 in the width direction, and the distance between adjacent second locking assemblies 5 or third locking assemblies 6 is less than the length of the decorative piece 1. It is worth noting that when both the second locking assembly 5 and the third locking assembly 6 are in the locking position, the distance between the end of the second locking block 52 and the end of the third locking block 62 is greater than the width of the first groove 13 on the decorative plate, so as to ensure the processing conditions for processing the first groove 13 on the decorative piece 1.

[0034] The front and back sides of the decorative piece 1 are fixed in different directions using the processing fixtures set in the aforementioned embodiments 1 and 2, thereby providing processing conditions for the first groove 13 and the second groove 1, and cooperating with the CNC machining center to complete the processing process of the first groove 13 and the second groove 1.

[0035] Example 3 A machining fixture for slotting decorative pieces, differing from the machining fixture proposed in Embodiment 2 in the setting of the positioning groove 3, such as... Figure 6 As shown, the positioning groove 3 includes a horizontal section 31 and a limiting section 32, wherein the limiting section 32 is a downwardly extending conical groove, and the end of the curved section 12 of the decorative piece 1 is located at the tip of the conical groove, that is, the inner side of the curved section 12 of the decorative piece 1 is set towards the positioning groove 3.

[0036] It is worth noting that the positioning groove 3 structure set in this embodiment is the same as the positioning groove 3 structure set in embodiment 1. Therefore, in order to fit the setting of the positioning groove 3, the locking component used in this embodiment should be a fourth locking component 7 composed of a second cylinder 51 and a first locking block 42. The length of the first locking block 42 is shortened. The second cylinder 51 drives the first locking block 42 to move up and down to complete the pressing of one end of the decorative piece 1 in the width direction, and the third locking component 6 completes the pressing of the other end of the decorative piece 1 in the width direction.

[0037] While the distance between the first locking block 42 and the third locking block 62 is greater than the width of the first groove 13 on the decorative piece 1, the distance between adjacent fourth locking components 7 located inside the decorative piece 1 must be greater than the length of the second groove 14 and less than the length of the decorative piece 1, in order to ensure the processing conditions of the first groove 13 and the second groove 14. By applying a processing fixture for slotting decorative pieces in this embodiment, the processing of the first groove 13 and the second groove 14 can be completed directly without step-by-step processing, greatly improving the processing efficiency of the decorative piece 1.

[0038] In summary, the decorative piece 1 is initially positioned by the positioning groove 3 set on the base 2. Then, the decorative piece 1 is further locked in the positioning groove 3 by the locking component 4 set at at least one end of the positioning groove 3. The distance between adjacent or opposite locking components 4 meets the processing requirements of the first groove 13 and the second groove 14 on the decorative piece 1, thereby obtaining a decorative piece 1 with uniform specifications and aesthetics.

[0039] 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.
