Description

Technical Field

[0001] The utility model belongs to the technical field of alignment tooling, and relates to an alignment tooling, in particular to a laser alignment tooling suitable for an armrest cover plate. Background Art

[0002] The positioning and drawing of decorative lines on automotive interiors, exteriors, and body panels require high precision. Automotive cladding alignment is a crucial step in automotive interior manufacturing, ensuring accurate stitching and smooth lines on the cladding material. This directly impacts the appearance, comfort, and durability of the interior components. Traditional manual alignment methods often result in poor control of decorative line spacing, leading to poor precision when fitting multiple cladding components together, making it difficult to ensure the accuracy and consistency of decorative lines. This is particularly true when working with complex shapes and curved surfaces such as center console armrests, center button surfaces, and rear panels. Manual alignment often results in uneven decorative line spacing and poor fitting accuracy, severely impacting the product's appearance and overall quality. Therefore, a more precise method for cladding alignment is necessary. Utility Model Content

[0003] This utility model aims to overcome the aforementioned problem of poor control of decorative line spacing, which leads to poor precision when fitting multiple covering components. By providing a alignment tool, specifically a laser alignment tool suitable for armrest upper covers, this tool provides precise alignment and easy adjustment, controlling the decorative line tolerance to within ±0.5mm, significantly improving product appearance and quality control.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] The utility model provides a line-aligning tool, including a base plate, on which a laser line-aligning device, a positioning membrane for positioning a product, and a support block for placing the product are provided. The product includes a first plate and a second plate connected by a bending connection, and a face cover sleeved on the first plate and the second plate. A decorative line is provided on the face cover above the first plate. The positioning membrane and the support block are arranged on the base plate in front and behind. The clamping limit of the second plate is located between the positioning membrane and the support block. The first plate is arranged on the support block. The laser line-aligning device includes a laser generator, which points to the first plate and projects onto the position of the decorative line. When the laser generator coincides with the decorative line, the product line is correctly aligned.

[0006] Furthermore, two laser marking correction blocks are symmetrically arranged on the bottom plate, and scale lines are provided on the laser marking correction blocks so that when the scale lines coincide with the scale lines on both sides, the alignment position and posture of the laser generator are correct.

[0007] Furthermore, the positioning fetal membrane and the laser marking correction block are fixed to the base plate by bolts.

[0008] Furthermore, a positioning protrusion or a positioning groove is provided on the positioning surface of the positioning membrane and / or the support block, and the positioning protrusion or positioning groove is matched with the groove or protrusion on the product.

[0009] Furthermore, a support rod is vertically provided on the bottom plate, a cross rod is provided on the top of the support rod, a mounting block is provided between the cross rod and the laser generator and is orthogonally arranged through the mounting block.

[0010] Furthermore, the mounting block includes a mounting block body and mounting slots orthogonally defined on either side of the body. Bolts are provided between the two side walls of the mounting slot, and nuts are attached to the bolts. By tightening the bolts and nuts, the two side walls are brought together, thereby clamping the crossbar and laser generator. The laser generator is the core component of the tooling, responsible for emitting laser markings to achieve precise positioning of the decorative lines. Fastening it to the mounting block with bolts and nuts ensures that the laser generator will not be affected by vibration or movement during alignment, which could affect alignment accuracy. This fixing method also facilitates maintenance and replacement of the laser generator.

[0011] Furthermore, when it is necessary to adjust the angle of the laser generator so that the laser marking line hits a specific position, the bolts and nuts on one side of the cross bar are screwed to move the two side walls of the mounting groove away from each other, so that the mounting block can rotate around the cross bar to adjust the angle of the laser generator. When adjusted to the required angle, the bolts and nuts on one side of the cross bar are screwed in the opposite direction to move the two side walls of the mounting groove back to a close state, thereby tightly clamping the cross bar to prevent the mounting block from rotating around the cross bar during use, thereby preventing the laser marking line projected by the laser generator from having a position deviation.

[0012] Furthermore, the support rod includes an adjusting bolt, an inner rod and an outer rod slidably mounted on the outer wall of the inner rod. The inner rod is provided with a through hole, and the outer rod is provided with a threaded hole passing through the side wall. One end of the adjusting bolt passes through the threaded hole and is embedded in the through hole to fix the inner rod and the outer rod.

[0013] Furthermore, the inner rod is provided with a plurality of through holes along the length direction.

[0014] Furthermore, the laser generator is electrically connected to an external power supply.

[0015] Furthermore, the positioning mold and the laser marking correction block are fixed to the base plate by bolts.

[0016] Furthermore, the sides of the bottom plate are provided with carrying handles, which facilitate the movement and carrying of the tooling, and make it easier for the operator to lift and move the entire tooling when in use.

[0017] Furthermore, the carrying handle is fixed by bolts.

[0018] Furthermore, a fixer is provided on the base plate, which is the basic supporting structure of the entire tooling, and the fixer is used to firmly fix the base plate on the ground or other horizontal surface to ensure the stability of the alignment process.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1) The alignment tooling proposed in this utility model can provide extremely high positioning accuracy, uniform spacing of decorative lines, and high matching accuracy, making the appearance of the armrest cover more beautiful and the overall quality more outstanding, ensuring the spacing of decorative lines and the matching accuracy of covering parts, and achieving precise alignment;

[0021] 2) Through precise mechanical design and advanced electronic control technology, the present invention can control the error of the decorative line within ±0.5mm. This level of accuracy far exceeds the traditional manual line setting method, greatly improving the appearance requirements and quality control of the product. Compared with manual line setting, the present invention greatly reduces the error caused by human factors, can significantly shorten the line setting time, and improve production efficiency.

[0022] 3) The utility model can adjust the alignment tooling according to the needs of different products to adapt to a variety of products such as central control armrests, central button surfaces and rear panels. BRIEF DESCRIPTION OF THE DRAWINGS

Unless otherwise specified, functional components or structures are conventional components or structures used in the art to achieve the corresponding functions.

[0032] Example:

[0033] A line-aligning tool comprises a base plate 7, on which is provided a laser line-aligning device, a positioning membrane 2 for positioning a hand-held upper cover plate, two laser-marking correction blocks 3 symmetrically arranged in parallel, and a support block 8 for placing the hand-held upper cover plate. The positioning membrane 2 and the laser-marking correction block 3 are fixed to the base plate 7 by bolts, and the positioning membrane 2 and the support block 8 are arranged on the base plate 7 one after the other, and the positioning surface of the positioning membrane 2 and / or the support block 8 are respectively provided with positioning protrusions or positioning grooves, which are adapted to the grooves or protrusions on the hand-held upper cover plate. The laser marking correction block 3 is provided with scale lines, so that when the laser marking line coincides with the scale lines on both sides, the positioning position of the laser generator 1 is correct; the hand-held upper cover plate includes a first plate and a second plate connected by a bend and a face cover mounted on the first plate and the second plate, a decorative line is provided on the face cover and above the first plate, and a positioning membrane 2 and a support block 8 are respectively provided on the front and rear of the bottom plate 7. The clamping limit of the second plate is located between the positioning membrane 2 and the support block 8, and the first plate is arranged on the support block 8. The laser positioning device includes a laser generator 1, which points to the first plate and projects the laser marking line onto the decorative line position. When the laser marking line coincides with the decorative line, the positioning of the hand-held upper cover plate is correct.

[0034] The base plate 7 is the basic support structure of the entire tooling. A support rod 5 is vertically mounted on the base plate 7. A crossbar 6 is mounted at the top of the support rod 5. A mounting block 9 is provided between the crossbar 6 and the laser generator 1 and is arranged orthogonally through the mounting block 9. The mounting block 9 includes a mounting block body and mounting slots orthogonally provided on both sides of the mounting block body. Bolts are provided between the two side walls of the mounting slot, and nuts are provided on the bolts. By screwing the bolts and nuts to bring the two side walls closer together, the crossbar 6 and the laser generator 1 are clamped. The support rod 5 includes an adjusting bolt 55, an inner rod 51, and an outer rod 52 that is slidably mounted on the outer wall of the inner rod 51. The inner rod 51 is provided with multiple through holes 53 along its length. The outer rod 52 is provided with a threaded hole 54 that passes through the side wall. One end of the adjusting bolt 55 passes through the threaded hole 54 and is embedded in the through hole 53 to fix the inner rod 51 and the outer rod 52. The laser generator 1 is the core component of the tooling, electrically connected to an external power source, and is responsible for emitting laser markings to achieve precise positioning of the decorative lines. It is fixed to the mounting block 9 by bolts and nuts, ensuring that the laser generator 1 will not be affected by vibration or movement during the alignment process, which may affect the alignment accuracy. At the same time, this fixing method also facilitates the maintenance and replacement of the laser generator. The base plate 7 is also provided with a carrying handle 4 and a fixture 12. The carrying handle 4 is relatively arranged on the side of the base plate 7 and is fixed to the base plate 7 by bolts. The carrying handle 4 facilitates the movement and carrying of the tooling, making it easy for the operator to easily lift and move the entire tooling during use. The fixture 12 is used to firmly fix the base plate 7 to the ground or other horizontal surface to ensure the stability of the alignment process.

[0035] The specific implementation process is as follows:

[0036] Place the alignment tool on the workstation, power on, and use the scale lines on the laser line correction block 3 to correct the laser line emitted by the laser generator 1. The specific correction process is as follows: the laser line hits the scale lines on the laser line correction block 3 on both sides, and the position and angular direction of the laser generator 1 light source are adjusted. When the laser line coincides with the corresponding scale lines on both sides, the alignment position of the laser generator 1 is correct. When it is necessary to adjust the light source position of the laser generator 1 so that the laser line hits a specific position, tighten the bolts and nuts on one side of the crossbar 6 to move the two side walls of the mounting groove away from each other. This allows the mounting block 9 to rotate around the crossbar 6, thereby adjusting the light source position of the laser generator 1. When the desired angular direction is reached, tighten the bolts and nuts on the mounting block 9 to adjust the angular direction of the light source so that the two side walls of the mounting groove return to a close state. Tighten the nuts and bolts on the block 9 to prevent the laser generator on the mounting block 9 from sliding during use, thereby preventing positional deviation of the laser line projected by the laser generator 1. When the positioning position of the laser generator 1 is correct, the correction is completed. Then the armrest upper cover 10 is placed on the support block 8 and the positioning membrane 2. The decorative line on the armrest upper cover 10 is calibrated by the laser generator 1. The laser generator 1 emits a laser marking line and projects it onto the armrest upper cover 10 to form a reference line. The operator adjusts the position of the decorative line according to the laser marking reference line to ensure that the straightness and position accuracy of the decorative line meet the set standards. After the decorative line positioning and calibration are completed, the armrest upper cover 10 is removed from the support block 8 and the positioning membrane 2.

[0037] The alignment tooling in the above embodiment can be adjusted accordingly according to the requirements of different products, such as a central control armrest, a central button panel, a rear panel and other products, so as to obtain a alignment tooling with wide applicability.
