Description

Technical Field

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

[0002] The surface processing of elongated decorative strips requires extremely high positioning accuracy. In existing technologies, the fixing and alignment of these strips have significant defects. Publicly available patent CN108406412A uses a single-point pneumatic locking method, which easily causes an arc-shaped deformation in the middle of the elongated strip. This is especially problematic for thin-walled strips with a length-to-width ratio greater than 20:1; localized stress during locking can lead to surface instability or inconsistent cutting depths during subsequent processing. Furthermore, in existing production lines, the strips are typically manually pushed to the reference edge, which is not only inefficient but also prone to human error, resulting in differences in the slotted positions between strips and affecting product consistency and aesthetics.

Detailed Implementation

[0022] 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.

[0023] A machining fixture for grooving the surface of trim strips, such as Figure 1 As shown, the device includes a base 9, on which a locking module 1 is mounted. The locking module 1 has a groove that matches the shape of the trim strip, and an alignment module 6 is fixedly mounted on one side of the locking module 1. The trim strip is manually placed into the locking module 1, and then aligned at the edges by the alignment module 6. Finally, the locking module 1 locks the trim strip in place, allowing subsequent processing to proceed.

[0024] The following combination Figure 1 and Figure 2 The locking module 1 is described in detail below. Locking module 1 includes a locking seat 2 and a pressing component 3. The locking seat 2 is fixedly mounted on the base 9, and a groove is formed in the base 9. The shape and depth of the groove are determined according to the edge shape and thickness of the trim strip, allowing the trim strip to be accurately placed in a fixed position on the locking seat 2. The pressing component 3 penetrates through the base 9 and the locking seat 2. After the trim strip is placed in the groove on the locking seat 2, the pressing component 3 presses the trim strip onto the locking seat 2 to complete the locking.

[0025] The aforementioned pressing assembly 3 includes a pressing block 4 and a first cylinder 5. The pressing block 4 is located above the aforementioned locking seat 2. The base 9 has a hollow structure. The first cylinder 5 is fixedly installed in the base 9, and the cylinder extension rod of the first cylinder 5 passes through the aforementioned base 9 and locking seat 2. The pressing block 4 is fixedly installed at the end of the extension rod of the first cylinder 5. The pressing block 4 is driven by the first cylinder 5 to reciprocate along the movement direction of the first cylinder 5.

[0026] In some embodiments, an anti-slip structure, such as an anti-slip texture, is provided in the slot of the locking seat 2, and an anti-slip structure is also provided on the side of the pressure block 4 facing the locking seat 2, so that after the trim strip is aligned by the alignment module 6, it is locked by the locking module 1. The anti-slip structure prevents relative displacement between the trim strip and the locking module 1 during the processing of the trim strip, thereby affecting the processing effect of the trim strip.

[0027] It is worth noting that, such as Figure 1 As shown, the aforementioned locking module 1 consists of two sets, distributed along the length of the base 9, to meet the maximum length requirement of the trim strip. The locking module 1 is positioned at both ends of the trim strip. A groove of a certain length needs to be machined in the middle of the trim strip, therefore the distance between the two sets of locking modules 1 must be greater than the length of the aforementioned groove, and this distance should be less than the length of the trim strip to meet the requirements for machining the groove of the trim strip.

[0028] In some embodiments, a slot is also machined near the end of the trim strip. In this case, the pressing block 4 should be located in the middle area between the slot and the groove, so that the trim strip is pressed onto the top of the base 9 by pressing the two ends of the trim strip together.

[0029] The following combination Figure 1 and Figure 3 The alignment module 6 is described in detail below. The alignment module 6 includes a second cylinder 7 and a push plate 8. The push plate 8 is fixedly mounted at the end of the telescopic rod of the second cylinder 7, and faces the locking module 1. Driven by the second cylinder 7, the push plate 8 reciprocates along the length of the second cylinder 7. After the trim strip is manually placed on the locking seat 2, the alignment module 6 aligns one end of the trim strip with the side of the locking seat 2 adjacent to the alignment module 6. The trim strip is then fixed by the cooperation between the pressure block 4 and the locking seat, completing the subsequent processing of the trim strip. By applying the alignment module 6, the differences in the processing positions of the grooves and holes on the trim strip caused by different positions after manual placement can be effectively eliminated, ensuring the consistency of the processed trim strips.

[0030] The processing of the trim strip mainly targets the middle section, while locking it occurs at both ends. Due to the length of the trim strip, the middle section may move up and down during processing, affecting the final result. Therefore, to ensure the stability of the groove in the middle section, a support component can be provided. For example... Figure 4As shown, the supporting assembly includes a supporting plate 10 disposed between two sets of locking modules 1 and a linkage assembly for connecting the pressure block 4 and the supporting plate 10. The aforementioned linkage assembly includes a gear 13, a first rack 11, and a second rack 12. Both the first rack 11 and the second rack 12 mesh with the gear 13, and the first rack 11 and the second rack 12 are arranged opposite each other on both sides of the gear 13. The pressure block 4 is fixed on the first rack 11, and the supporting plate 10 is fixed on the second rack 12. When the pressure block 4 rises under the action of the cylinder, the first rack 11 rises synchronously under the drive of the pressure block 4, which drives the gear 13 to rotate counterclockwise. The second rack 12 sinks under the drive of the gear 13, and synchronously drives the supporting plate 10 to sink. To facilitate the downward movement of the support plate 10, a slot with a size similar to that of the support plate 10 is provided on the base, and the length of the support plate 10 is not less than the length of the groove processed in the middle section of the trim strip; when the pressure block 4 is pressed down by the cylinder, the support plate 10 will be driven to rise by the linkage component.

[0031] To reduce wear on the side of the trim facing the support plate 10 during processing, an elastic support layer 14 is provided on the side of the support plate 10 facing the trim to provide soft support and reduce rigid contact and friction between the trim and the support plate 10, thereby ensuring the aesthetic appearance of the trim surface.

[0032] In some embodiments, the base 9 includes multiple sets of alignment modules 6 and locking modules 1. The multiple sets of alignment modules 6 and locking modules 1 are arranged parallel to each other at equal intervals along the width direction of the base 9 to fix multiple decorative strips, avoid frequent placement and removal of decorative strips during the processing of decorative strips, and help improve the processing efficiency of decorative strips.

[0033] The locking module 1 is used to fix the trim strip, and the alignment module 6 is used to align the ends of the trim strip, ensuring the consistency of the trim strip processing. Multiple alignment modules 6 and locking modules 1 can be set on the base 9 along its width direction to cooperate with each other, providing conditions for fixing multiple trim strips at the same time and improving the efficiency of trim strip processing.

[0034] 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.
