Description

Technical Field

[0001] This utility model relates to an auxiliary clamp for sewing car seat covers. Background Technology

[0002] Car seat covers are coverings that encase the foam padding on car seats, protecting the seat cushions and enhancing the overall aesthetics of the car's interior. Car seat covers are typically made by sewing together fabric, leather, or synthetic material pieces. Different fabrics have different properties, giving car seat covers characteristics such as softness and durability. Currently, during the sewing process, the edges of the seat back pockets, other edges of the cover pieces, and the seams are all manually controlled. Because manual sewing is uncontrollable, it can lead to inconsistent seam widths, misaligned seams, and wrinkled or twisted threads. This results in wrinkles, dents, and looseness on the seats after the cover is applied. Furthermore, manual sewing is inefficient, leading to a high defect rate and reduced seat production efficiency. Utility Model Content

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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.

[0019] like Figure 1 As shown, this utility model discloses an auxiliary clamp for sewing automotive seat covers, applicable to industrial sewing machines, aiming to improve sewing efficiency and yield. The clamp includes a fixed base plate 1 for mounting to the industrial sewing machine table. A support rail 2 is horizontally arranged above the fixed base plate 1, and a sliding bracket 21 is slidably connected to the support rail 2. One end of the sliding bracket 21 is provided with a seam allowance positioning block 23 extending downwards for positioning the seam allowance. In use, the clamp is fixed to the industrial sewing machine table via the fixed base plate and located to the right of the presser foot. By moving the sliding bracket along the support rail, the required seam allowance width can be adjusted. Then, the cut piece is fed into the sewing area for sewing. The seam allowance of the cut piece is tightly pressed against the seam allowance positioning block during sewing. This prevents the seam from being skewed left or right, or the seam allowance from being uneven in width, thus solving appearance problems such as wrinkles and dents after seat covers are installed, and improving the overall aesthetics of the seat. This fixture can help sewing workers reduce folding errors, improve sewing efficiency, reduce defect rate, improve the aesthetics of the seat, and increase seat production efficiency while also reducing labor costs.

[0020] In this embodiment, the seam allowance positioning block 23 is stepped, the upper vertical section of the seam allowance positioning block 23 is fixedly connected to one end face of the sliding bracket 21, and the lower vertical section of the seam allowance positioning block 23 is designed to fit tightly against the seam allowance.

[0021] In this embodiment, a rotating bracket 3 is rotatably connected to the middle of the fixed base plate 1, and the support guide rail 2 is installed on the upper end of the rotating bracket 3. The rotating bracket is used to rotate the entire clamp parallel to the sewing presser foot when the seam allowance needs to be turned at a corner or when auxiliary clamps are not used, making the sewing operation convenient and eliminating the need for repeated installation.

[0022] Specifically, the rotating bracket 3 includes a cylindrical rotating part 30 and a support part 31 disposed on the top of the rotating part 30. The rotating part 30 is rotatably connected to the circular hole in the middle of the fixed base plate 1. One end of the support guide rail 2 is provided with a downwardly extending connecting protrusion 27. The connecting protrusion 27 extends into the support part 31 and is locked and fixed to the support part 31 by fixing bolts 24, thereby fixing the rotating bracket and the support guide rail together.

[0023] In this embodiment, the support guide rail 2 is provided with a horizontal groove 26 that runs through the horizontal direction, and the cross-section of the horizontal groove 26 is rectangular; the sliding bracket 21 is rectangular in shape and slides through the horizontal groove 26. The position of the seam allowance positioning block can be adjusted by extending the horizontal groove and moving the sliding bracket.

[0024] In this embodiment, the top of the sliding bracket 21 is provided with a display scale 22 extending along its length.

[0025] In this embodiment, a pair of limiting screws 20 are screwed onto the end of the support guide rail 2 away from the seam allowance positioning block 23. The pair of limiting screws 20 extend into the horizontal slide groove 26 and are used to lock the sliding bracket 21. After the position of the sliding bracket is adjusted, the sliding bracket is locked by the pair of limiting screws.

[0026] In this embodiment, the sliding bracket 21 has a vertically penetrating weight-reducing through hole 25, which is elongated and extends along the length of the sliding bracket.

[0027] In this embodiment, the fixed base plate 1 is provided with a fixing hole 10. The fixed base plate 1 is locked to the industrial sewing machine table by fasteners (such as screws) that pass through the fixing hole 10, so that the clamp is firmly fixed and not easy to deviate or tilt. The clamp is very convenient to install and disassemble.

[0028] The specific operation is as follows: Install the clamp onto the industrial sewing machine table for sewing car seat covers, then adjust the required seam allowance width by sliding the bracket, fix the limit screw after adjustment, and then feed the cut piece into the sewing area for sewing. The seam allowance of the cut piece is tightly attached to the seam allowance positioning block for sewing operations.

[0029] This clamp can be installed on any industrial sewing machine table for sewing car seat covers. The fixed base plate is secured with screws, ensuring that the cover pieces and seam allowance positioning blocks will not be skewed during sewing operations. The seam allowances will not be uneven in width, and the seams will not be skewed or twisted. The addition of a rotating function (the support rail can rotate) makes sewing operations convenient and intermittent, eliminating the need for repeated installation. The clamp is also very easy to install and remove, solving the problems of uncontrollable manual sewing operations and the drawbacks of uneven seam allowances and skewed seams. It achieves the goals of reliable and stable performance, simple and easy operation, improved production efficiency, and reduced labor costs.

[0030] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral molding process).

[0031] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0032] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.
